FOS addiction reward 25481016 In the current study, effects of acute and subchronic stress on the alteration of p ERK, p CREB and c fos levels in the hypothalamus and hippocampus of saline or morphine treated animals during morphine induced conditioned place preference (CPP) procedure were investigated. FOS addiction reward 25481016 In all of groups, the CPP procedure was done, afterward the alternation of p ERK/ERK ratio, p CREB/CREB ratio and c fos level in the hypothalamus and hippocampus were estimated by Western blot analysis. FOS drug opioid 25481016 The results indicated that in saline or morphine treated animals, p ERK/ERK ratio, p CREB/CREB ratio and c fos level increased after application of acute and subchronic stress (except for p ERK/ERK ratio in morphine control group). FOS drug opioid 25481016 Our findings revealed that in saline or morphine treated animals, acute and subcronic stress increased the p ERK/ERK ratio, p CREB/CREB ratio and c fos level in the hypothalamus and hippocampus and this enhancement in morphine treated animals, was more considerable than that in saline treated animals. FOS drug cocaine 25451087 Region specific effects of isoflurane anesthesia on Fos immunoreactivity in response to intravenous cocaine challenge in rats with a history of repeated cocaine administration. FOS drug cocaine 25451087 administration of cocaine increases Fos immunoreactivity in rats under isoflurane anesthesia. FOS drug cocaine 25451087 Given that Fos expression is a marker of neural activation, the results suggested that isoflurane is appropriate for imaging cocaine effects under anesthesia. FOS drug cocaine 25451087 We found that challenge injections of cocaine following a regimen of repeated cocaine exposure resulted in Fos expression in the prefrontal cortex and striatum roughly equivalent to that found in rats who had received the cocaine challenge after a history of vehicle injections. FOS drug cocaine 25451087 Additionally, isoflurane anesthesia resulted in a heterogeneous attenuation of cocaine induced Fos expression, with the most robust effect in the orbital cortex but no effect in the nucleus accumbens core (NAcC). FOS drug cocaine 25451087 These results indicate that cocaine induced Fos is preserved in the NAcC under isoflurane, suggesting that isoflurane can be used in imaging studies involving cocaine effects in this region. FOS drug amphetamine 25446574 At the end of behavioral experiments, in order to evaluate the effect of LV siRNA on D1aR expression, rats were challenged with amphetamine and the brains were processed for immunohistochemical detection of c Fos and D1aR.

FOS drug nicotine 25430056 Both cFos and phosphorylated cJun (p cJun) were immediately increased in the nucleus, together with an increase of calmodulin kinase (CaMK) IV but not CaMKII expression after nicotine exposure. FOS drug nicotine 25430056 A nonselective inhibitor of CaMKs, KN 93, and a calcium chelating regent, BAPTA AM, completely suppressed the expression of cFos and p cJun in the nucleus as well as the nicotine induced IP3 R 1 upregulation. FOS drug nicotine 25430056 These results indicate that nAChR activation by nicotine upregulates IP3 R 1 via increase of activator protein 1, which is a cFos and cJun dimmer, in the nucleus, with activation of Ca(2+) signaling transduction processes. FOS drug opioid 25425322 Lastly, food and opioid cues engaged similar amygdalo striatal thalamic circuitry to a much greater extent in STs than GTs, as indicated by Fos expression. FOS drug opioid 25424867 Retrieval of morphine associated context induces cFos in dentate gyrus neurons. FOS addiction reward 25424867 This associative learning has a cellular correlate, as there are more cFos+ neurons in the hippocampal dentate gyrus (DG) after psychostimulant conditioned place preference (CPP) versus saline controls. FOS addiction reward 25424867 To explore this, we employed an unbiased, counterbalanced, and shortened CPP design that led to place preference and more DG cFos+ cells. FOS drug opioid 25424867 Morphine paired mice sequestered to CS+ had ∼30% more DG cFos+ cells than saline paired mice. FOS drug opioid 25424867 Furthermore, Bregma analysis revealed morphine paired mice had more cFos+ cells in CS+ compared to CS controls. FOS drug opioid 25424867 Notably, there was no significant difference in DG cFos+ cell number after handling alone or after receiving morphine in home cage.

FOS drug cocaine 25290264 Under cocaine, the attenuated DA and 5 HT activation in αCaMKII(T286A) mice was followed by impaired c Fos activation in the NAcc. FOS drug opioid 25290009 Although morphine was previously reported to produce an instant induction of c fos in the striatum, our recent studies have demonstrated that the expression of numerous immediate early genes (IEGs) is significantly elevated at delayed time points (several hours) after morphine administration. FOS drug opioid 25290009 To better dissect the time course of opioid produced IEG induction, we used in situ hybridization to examine the expression of the IEGs c fos, zif268 and arc in the mouse forebrain at several time points after acute morphine injection.

FOS addiction withdrawal 25229718 Using immunohistochemistry and whole cell patch clamp electrophysiology, we also found that CIE increased FOS IR and enhanced neuronal excitability in the ventral BNST (vBNST) 24 h into withdrawal in a 5HT2c R dependent manner. FOS drug nicotine 25223294 Mouse brains were examined by immunohistochemistry for c Fos protein after intraperitoneal injection of either nicotine hydrogen tartrate salt (NIC; 30 and 40 μg/kg) or nicotine pyrrolidine methiodide (NIC PM; 20 and 30 μg/kg). FOS drug alcohol 25149913 In the present study, alcohol induced adaptations in (1) anxiety like behavior, (2) patterns of c Fos activation and (3) subcellular distribution of corticotropin releasing factor receptor in locus coeruleus (LC) neurons was investigated in male and female Sprague Dawley rats that were chronically exposed to ethanol using a liquid diet. FOS drug alcohol 25149913 Ethanol induced sex differences were observed with increased c Fos expression in LC neurons of female ethanol treated subjects compared to controls or male subjects. FOS drug amphetamine 25145867 Combining quantitative analyses of cfos expression with neuronal subtype specific markers at single cell resolution, we show that acute d amphetamine administration leads to both increased neuronal activation and the recruitment of neurons in the medial (Dm) and the lateral (Dl) domains of the adult zebrafish pallium, which contain homologous structures to the mammalian amygdala and hippocampus, respectively. FOS drug alcohol 25126745 Herein, we examined whether the decrease in IFN γ is resulted from altered expression of miRNA155 and transcription factors NFAT, Tbx21, Jun and Fos in T cells following ethanol and burn injury. FOS drug alcohol 25126745 We observed a significant decrease in miRNA155, NFAT, Tbx21, Jun and Fos expression as well as IFN γ release in T cells cultured with anti CD3 following ethanol and burn injury compared with shams. FOS drug opioid 25086310 To test whether these substances act similarly on the same neuronal populations in specific brain areas mediating these behaviors, we administered the substances short term, using the same methods and within the same experiment, and measured their effects, in areas of the hypothalamus (HYPO), amygdala (AMYG), and nucleus accumbens (NAc), on mRNA levels of the opioid peptide, enkephalin (ENK), using in situ hybridization and on c Fos immunoreactivity (ir) to indicate neuronal activity, using immunofluorescence histochemistry. FOS drug alcohol 25086310 Fat, ethanol, and nicotine, but not sucrose, increased the single and double labeling of ENK and c Fos ir in precisely the same brain areas, the middle parvocellular but not lateral area of the paraventricular nucleus, central but not basolateral nucleus of the AMYG, and core but not shell of the NAc. FOS drug nicotine 25086310 Fat, ethanol, and nicotine, but not sucrose, increased the single and double labeling of ENK and c Fos ir in precisely the same brain areas, the middle parvocellular but not lateral area of the paraventricular nucleus, central but not basolateral nucleus of the AMYG, and core but not shell of the NAc. FOS drug cocaine 25050821 Cocaine self administration and extinction alter medullary noradrenergic and limbic forebrain cFos responses to acute, noncontingent cocaine injections in adult rats. FOS drug cocaine 25050821 The present study examined the ability of acute cocaine to induce the immediate early gene product, cFos, in NA neurons and stress related neural circuits in rats that were cocaine naïve, or had a history of cocaine self administration with or without extinction. FOS drug cocaine 25050821 Extinction attenuated cocaine induced cFos activation in NA neurons of the caudal ventrolateral medulla (A1/C1 cell groups), and attenuated cFos within the paraventricular nucleus of the hypothalamus, the apex of the central neuroendocrine stress axis. FOS drug cocaine 25050821 Cocaine consistently increased cFos in the bed nucleus of the stria terminalis, regardless of history.

FOS addiction withdrawal 25042794 c Fos expression decreased in the dentate gyrus of the hippocampus (DG) and the bed nucleus of the stria terminalis (BST), and increased in the habenular (Hb), accumbens shell (AcbSh) nuclei during NIC withdrawal. FOS addiction withdrawal 25042794 BAC re established the modified c Fos expression only in the DG, BST and AcbSh during NIC withdrawal. FOS addiction withdrawal 25042794 The results suggest a relationship between BAC's preventive effect of the expression of NIC withdrawal signs, and its ability to restore the changes in c Fos and BDNF expression, observed in specific brain areas of NIC withdrawn mice. FOS drug opioid 25025380 Compared to oxycodone self administering control rats immunized with the carrier alone, rats vaccinated with the OXY KLH immunogen showed increased levels of adenylate cyclase 5 (Adcy5) and decreased levels of early growth response protein 2 (Egr2) and the early immediate gene c Fos in the striatum.

FOS drug cocaine 24813699 Very recently, we have shown that conditioned preference for an odour associated with cocaine was directly correlated with cFOS expression in cells at the dorsal region of the granule cell layer of the cerebellar vermis. FOS drug cocaine 24813699 The main goal of the current investigation was to further extend the description of cFOS IR patterns in cerebellar circuitry after training mice in a cocaine odour Pavlovian conditioning procedure, including now the major inputs (the inferior olive and pontine nuclei) and one of the output nuclei (the medial deep nucleus) of the cerebellum. FOS drug cocaine 24813699 The results showed that the cerebellar hallmark of preference towards an odour cue associated to cocaine is an increase in cFOS expression in the dorsal part of the granule cell layer. FOS drug cocaine 24813699 cFOS IR levels expressed in the granule cell layer of mice that did not show cocaine conditioned preference did not differ from the basal levels. FOS drug cocaine 24813699 Remarkably, mice subjected to a random cocaine odour pairing procedure (the unpaired group) exhibited higher cFOS IR in the inferior olive, the pontine nuclei and in the deep medial nucleus.

FOS drug cocaine 21886557 Recently, methanolic extracts from licorice was reported to decrease cocaine induced dopamine release and c Fos expression in the nucleus accumbens. FOS drug cocaine 21886557 In addition, LQ inhibited CREB phosphorylation and c Fos expression in the striatum and the nucleus accumbens induced by acute cocaine. FOS drug cocaine 21886552 We generated and analyzed genetically engineered mouse models and found that the D1 receptor and c Fos expressed in D1 receptor bearing neurons mediate the locomotor sensitization and reinforcing effects of cocaine.

FOS addiction sensitization 21886552 We generated and analyzed genetically engineered mouse models and found that the D1 receptor and c Fos expressed in D1 receptor bearing neurons mediate the locomotor sensitization and reinforcing effects of cocaine. FOS drug cocaine 21886552 Notably, a lack of Fos expression in D1 receptor bearing neurons in mice results in no change in the induction but a significantly delayed extinction of cocaine induced conditioned place preference. FOS drug cocaine 21886552 These findings suggest that D1 receptor mediated and c Fos regulated changes in cell signaling and gene expression may play key roles in the extinction process, and they provide a foundation for further exploring mechanisms underlying extinction of cue elicited cocaine seeking.

FOS drug cocaine 21880920 In addition, several lines of evidence suggest that adaptive changes occurred in both the ventral and dorsal striatum in the absence of VGLUT2: DA receptor binding was increased, and basal mRNA levels of the DA induced early genes Nur77 and c fos were elevated as after cocaine induction. FOS drug nicotine 21831361 c Fos expression was analyzed in several brain areas related to nicotine dependence by immunofluorescence techniques. FOS addiction dependence 21831361 c Fos expression was analyzed in several brain areas related to nicotine dependence by immunofluorescence techniques. FOS drug nicotine 21831361 Nicotine withdrawal increased the percentage of hypocretin cells expressing c Fos in the perifornical, dorsomedial, and lateral hypothalamus. FOS addiction withdrawal 21831361 Nicotine withdrawal increased the percentage of hypocretin cells expressing c Fos in the perifornical, dorsomedial, and lateral hypothalamus. FOS addiction withdrawal 21831361 In addition, the increased c Fos expression in the PVN during withdrawal was dependent on hypocretin transmission through Hcrtr 1 activation. FOS drug opioid 21791964 Many studies have suggested that the behavioral and reinforcing effects of morphine are induced by hyperactivation of the mesolimbic dopaminergic system, which results in increases in locomotor activity, c Fos expression in the nucleus accumbens (NAc), and tyrosine hydroxylase (TH) in the ventral tegmental area (VTA).

FOS addiction sensitization 21791964 In order to investigate the effect of wild ginseng (WG) on treating morphine addiction, we examined the behavioral sensitization of locomotor activity and c Fos and TH expression in the rat brain using immunohistochemistry. FOS drug opioid 21791964 Intraperitioneal injection of WG (100 and 200 mg/kg), 30 min before administration of a daily injection of morphine (40 mg/kg, s.c.), significantly inhibited morphine induced increases in c Fos expression in NAc and TH expression in VTA as well as in locomotor activity, as compared with Panax ginseng. FOS drug opioid 21782156 Thus, c Fos, FosB/ΔFosB and P CREB immunoreactive profiles were quantified in the rat CPu after either acute or continuous (6 day) administration of morphine and/or PD168,077. FOS drug opioid 21782156 Interestingly, at some time points, combined treatment with morphine and PD168,077 substantially increased c Fos, FosB/ΔFosB and P CREB expression. FOS drug alcohol 21762292 Moreover, increased ethanol consumption was associated with lowered blood corticosterone levels, indicating a blunted HPA signaling, which was reversed by intra PVN injection of picrotoxin, as indicated by the increased Fos immunostaining positive cells in the PVN and the increased blood corticosterone levels.

FOS drug amphetamine 21570990 Here we investigate whether mPFC neurons innervating the VTA exhibit altered Fos or BDNF expression during long term sensitization to amphetamine. FOS addiction sensitization 21570990 Here we investigate whether mPFC neurons innervating the VTA exhibit altered Fos or BDNF expression during long term sensitization to amphetamine. FOS drug amphetamine 21570990 Amphetamine challenge increased Fos and BDNF expression in the mPFC regardless of prior drug experience, and further augmented mPFC BDNF expression in sensitized rats. FOS drug amphetamine 21570990 Similarly, more Fos FG and Fos BDNF double labeling was observed in the mPFC of sensitized rats compared to drug naïve rats after amphetamine challenge. FOS drug amphetamine 21570990 Repeated amphetamine treatment also increased VTA BDNF, while both acute and repeated amphetamine treatment increased Fos and Fos BDNF co labeling, an effect enhanced in sensitized rats. FOS drug opioid 21524693 Morphine conditioned cue alters c Fos protein expression in the brain of crayfish. FOS drug opioid 21524693 In the third experiment, we found that the c Fos profile of morphine treated crayfish in an unconditioned environment did not show a significant increase from the basal level comparable to saline treated crayfish. FOS drug opioid 21524693 These results indicate that chronic morphine treatment alone is not sufficient to induce changes in the expression of c Fos; instead, morphine environment pairing in a specific context contributes to the expression of alterations in c Fos regulation. FOS addiction addiction 21524693 The enhancement of c Fos expression in the brain of crayfish seems to reflect the sensory or anticipatory facets of conditioning that suggests that potential and even unanticipated hypotheses in drug addiction can emerge from studies of addiction in crayfish. FOS drug nicotine 21501256 To determine whether there are different subgroups of 5 HT cells activated during nicotine administration and withdrawal, we mapped the appearance of Fos, a marker of neuronal activation, in 5 HT cells of the dorsal raphe nucleus (DR) and median raphe nucleus (MR).

FOS drug alcohol 21477621 In animals subjected to the acute severe stress of naltrexone induced morphine withdrawal, treatment with the NK(1) antagonist, L733,060, produced reductions in Fos LI in the spinal dorsal horn, whereas those treated with the NK(3) antagonist, SSR146,977, 0.3mg/kg, had reduced Fos LI in the dorsal horn, adrenal medulla, nucleus accumbens, ventral tegmental area and periaqueductal grey.

FOS drug nicotine 21412223 Neurochemical analyses of c fos mRNA expression, and of monoamine transmitter and transporter levels, showed that forebrain limbic systems are continuing to develop during early adolescence, and that this maturation is critically altered by brief nicotine exposure. FOS drug nicotine 21412223 Nicotine selectively increased c fos mRNA expression in the nucleus accumbens shell and basolateral amygdala in adolescent, but not adult animals, and altered serotonin markers in these regions as well as the prefrontal cortex.

FOS drug amphetamine 21326191 This effect was not related to differences in the ability to attribute predictive value to a conditioned stimulus (as measured by conditioned approach behavior), but was potentially linked to the development of behavioral supersensitivity to amphetamine and to augmented amphetamine induced immediate early gene expression (c fos and Nur77) in dorsal striatopallidal and striatonigral cells. FOS drug alcohol 21300146 When another group of adolescent binge drinking rats was administered alcohol in adulthood, the number of colocalized c fos ir and PNMT ir cells/brain stem section in the C3 area was significantly decreased, compared to controls.

FOS drug opioid 21216264 Morphine did not significantly enhance, but suppressed Fos expression in certain brain regions of drug naïve WLP and WHP rats. FOS drug opioid 21216264 Fos expression revealed considerable differences in the responses of WLP and WHP rats to morphine challenge, particularly after methadone pretreatment. FOS addiction relapse 21209913 Expression of the protein product of the neuronal activity marker c fos was assessed in a number of brain regions of mice that exhibited reinstatement (R mice) versus those which did not (NR mice). FOS addiction relapse 21209913 Reinstatement generally conferred greater Fos expression in cortical and limbic structures previously implicated in drug seeking behaviour, though a number of regions not typically associated with drug seeking were also activated. FOS addiction sensitization 21184750 The interaction of AF and VCS on Fos expression in the MPOA suggests that POEF may enhance vaginal cervical sensory input at parturition to facilitate sensitization of the MPOA, and presumably facilitate maternal behavior onset. FOS drug nicotine 21125398 Furthermore, nicotine increased c Fos expression in the CeA, but not the medial or basolateral amygdaloid nucleus. FOS drug cocaine 21123561 Neuronal activation, as assessed by Fos expression, was greatly reduced in the dorsal and ventral bed nucleus of the stria terminalis (BNST), lateral septum, and nucleus accumbens shell in mice lacking CREB (CREBαΔ mice) after a 6 min swim stress but not after cocaine exposure (20 mg/kg). FOS drug opioid 21068718 Microinjection of recombinant TNFα into the vlPAG followed by intraperitoneal naloxone resulted in morphine withdrawal like behavioral signs, and upregulation of pERK1/2, expression of Fos, and phosphorylation of cAMP response element binding (pCREB) protein.

FOS addiction relapse 20973776 Immediate reinstatement increased Fos expression in the nucleus accumbens (NAc), infra limbic (IL), pre limbic (PrL), orbitofrontal (OFC) and piriform cortices, the lateral and dorsomedial hypothalamus, central amygdala and basolateral amygdala (BLA), and the bed nucleus of the stria terminalis. FOS addiction relapse 20973776 Following delayed reinstatement, Fos expression was further elevated in cortical structures. FOS addiction relapse 20973776 Concurrent with preventing reinstatement, SB 334867 decreased Fos in NAc core, PrL and OFC following immediate reinstatement. FOS addiction relapse 20973776 Following protracted abstinence, SB 334867 treatment decreased reinstatement induced Fos in the PrL, OFC and piriform cortices. FOS addiction relapse 20973776 The effects of SB 334867 on both behaviour and Fos expression suggest that the orexin system is implicated in cue induced reinstatement, although some loci may shift following protracted abstinence.

FOS drug amphetamine 20950675 METH injection significantly increased Fos expression in several brain regions including nucleus accumbens (NA), caudate putamen (CPU), ventral tegmental area (VTA), substantia nigra (SN) and locus coeruleus (LC). FOS drug amphetamine 20950675 Interestingly, BV (1mg/ml) injection into ST36 further increased METH induced Fos expression in NA (core and shell), SN and LC. FOS drug amphetamine 20950675 When we performed sciatic denervation or combination treatment of BV and lidocaine (BV diluted in 5% lidocaine solution), the enhancement of Fos elevation by BV was completely blocked in the NA, SN and LC in METH injected mice, indicating that BV induced peripheral nerve stimulation played an important role in the BV effect. FOS drug amphetamine 20950675 Taken together, these findings suggest that BV acupuncture into ST36 may modulate METH induced hyperactivity, hyperthermia and Fos expression through activation of the peripheral nerve and the central α₂ adrenergic activation. FOS addiction aversion 20937363 The role of the central nucleus of the IC (CIC) on fear and anxiety has been suggested on the basis that rats are able to engage in tasks to decrease the aversiveness of CIC stimulation, increased Fos immunolabeling during diverse aversive states and increased CIC auditory evoked potentials (AEP) induced by conditioned fear stimuli.

FOS addiction withdrawal 20807311 Next, we examined c Fos expression (marker of neuronal activation) in BF wake promoting neurons during ethanol withdrawal. FOS drug amphetamine 20731630 Strikingly, oxytocin significantly reduced methamphetamine induced Fos expression in two regions of the basal ganglia: the subthalamic nucleus and the nucleus accumbens core. FOS addiction reward 20716371 Administration of the GABAA receptor antagonist picrotoxin into rat supramammillary nucleus induces c Fos in reward related brain structures. FOS drug cocaine 20704593 Our results show that SSRIs potentiate methylphenidate induced expression of the transcription factor genes zif268 and c fos in the striatum, rendering these molecular changes more cocaine like. FOS drug amphetamine 20680358 Repeated administration of methamphetamine blocked cholecystokinin octapeptide injection induced c fos mRNA expression without change in capsaicin induced junD mRNA expression in rat cerebellum. FOS drug amphetamine 20680358 First, injections of CCK 8 were found to induce c fos mRNA expression in a vague patchy pattern that is different from single methamphetamine induced Zebrin band like c fos mRNA expression, suggesting that the CCK 8 activating mossy fibers induce gene expression differently from the dopamine containing mossy fibers in the ventral tegmental area. FOS drug amphetamine 20680358 Repeated administration of methamphetamine suppressed the CCK 8 induced c fos mRNA expression in the rat cerebellum. FOS drug amphetamine 20680358 Third, capsaicin injections (physical stress) into a hind limb of the rat increased junD mRNA expression with no effect on c fos mRNA expression, and repeated methamphetamine injections had no effect on the capsaicin induced expression of junD mRNA. FOS drug amphetamine 20680358 Fourth, either single injection of methamphetamine or CCK 8 to mice increased c fos mRNA expression in the locus coeruleus, and so noradrenalin, but not dopamine, might interact with CCK 8 activating system. FOS drug amphetamine 20680358 Thus, we conclude that repeated methamphetamine administration though dopamine selectively inhibits the c fos mRNA expression after CCK 8 injection in the cerebellum.

FOS drug cocaine 20633205 We found that cFos, FosB, and ΔFosB exhibit regionally and temporally distinct expression patterns, with greater accumulation of ΔFosB protein in the nucleus accumbens (NAc) shell and core after chronic cocaine administration, whereas ΔFosB increases in the caudate putamen (CPu) remained similar with either acute or chronic administration. FOS drug cocaine 20633205 Interestingly, tolerance to cocaine induced cFos induction was dependent on volitional control of cocaine intake in ventral but not dorsal striatal regions, whereas regulation of FosB and ΔFosB was similar in cocaine self administering and yoked animals.

FOS drug cocaine 19794406 Fos after single and repeated self administration of cocaine and saline in the rat: emphasis on the Basal forebrain and recalibration of expression. FOS drug cocaine 19794406 We evaluated a large sample of brain structures, particularly ones comprising basal forebrain macrosystems, and determined in which the immediate early gene product, Fos, is expressed following a single and repeated self administrations of cocaine. FOS drug cocaine 19794406 The caudate putamen and accumbens, comprising the basal ganglia input structures, and the hypothalamic supraoptic and paraventricular nuclei, lateral and medial habenula, mesopontine rostromedial tegmental nucleus and anterior cingulate cortex exhibited Fos expression enhanced by acute self administration of cocaine (SAC), but desensitized after repeated administrations. FOS drug cocaine 19794406 Fos expression was mainly enhanced by acutely self administered cocaine in basal ganglia output and intrinsic structures and the intermediate nucleus of lateral septum, medial division of the central amygdaloid nucleus and zona incerta, but, in contrast, was sensitized in these structures after repeated administrations. FOS drug cocaine 19794406 Acute and repeated SAC left Fos expression unaffected or marginally enhanced in most extended amygdala structures, of which nearly all, however, exhibited robustly increased Fos expression after repeated saline self administration, occasionally to levels exceeding those elicited by cocaine. FOS drug cocaine 19794406 Thus, self administered cocaine mainly elicits Fos expression, which persists or increases with repeated administrations in some structures, but declines in others. FOS drug cocaine 19794406 Similar spatiotemporal patterns of cocaine or saline elicited Fos expression characterize functionally related clusters of structures, such as, eg, basal ganglia input structures, basal ganglia output structures, extended amygdala and structures in the brainstem to which forebrain macrosystems project.

FOS addiction withdrawal 19116947 These data indicate that region specific changes in PD and c fos expression occur after withdrawal, while SERT mRNA expression is suppressed, similar to what has been reported in MDD. FOS addiction withdrawal 19116947 Alterations in PD, c fos, and SERT expression could contribute to the depression like syndrome associated with psychostimulant withdrawal. FOS drug amphetamine 19084559 Expression of c fos mRNA in the basal ganglia associated with contingent tolerance to amphetamine induced hypophagia. FOS drug amphetamine 19084559 Following an acute injection of amphetamine, both of these groups had higher levels of c fos mRNA than saline treated controls throughout the striatum, in the nucleus accumbens core, the ventral pallidum and layers V VI of the motor cortex. FOS drug amphetamine 19084559 In contrast, tolerant rats, which had learned to suppress stereotypy, had higher levels of c fos mRNA than both amphetamine and saline treated controls in the entopeduncular nucleus, globus pallidus, subthalamic nucleus, pedunculopontine nucleus, nucleus accumbens shell, olfactory tubercle, somatosensory cortex, and layers II IV of motor cortex.

FOS addiction sensitization 19020866 Persistence of one trial cocaine induced behavioral sensitization in young rats: regional differences in Fos immunoreactivity. FOS addiction sensitization 19020866 The purpose of this study was to determine whether: (1) the context dependent and context independent sensitization of young rats can be dissociated based on the persistence of the sensitized response and (2) the expression of behavioral sensitization is associated with region specific increases in Fos immunoreactivity (Fos IR). FOS drug cocaine 19020866 When assessed after three abstinence days (i.e., on PD 22), acute treatment with cocaine increased Fos IR in various brain regions, but sensitized responding was associated with elevated Fos expression in only the caudate putamen (CP) and prefrontal cortex (PFC). FOS addiction sensitization 19020866 Fos data indicate that the CP and PFC may be involved in the mediation of short term behavioral sensitization on PD 22. FOS addiction reward 18996447 Surprisingly, Fos immunoreactivity was not observed with either GHB or baclofen in reward relevant regions such as the nucleus accumbens, striatum and ventral tegmental area. FOS drug cocaine 18991842 c Fos is an intracellular regulator of cocaine induced long term changes. FOS drug cocaine 18991842 Using a genetically modified mouse in which Fos is primarily mutated in D1 receptor bearing neurons in the brain, we examined a potential role of the immediate early gene Fos, which is rapidly induced by cocaine via D1 receptors, in mediating cocaine induced persistent neurobiological changes. FOS drug cocaine 18991842 We found that the composition of AP 1 transcription complexes and expression levels of AP 1 complexes, and several transcription factors, neurotransmitter receptors as well as intracellular signaling molecules following repeated cocaine administration are altered in Fos deficient brains. FOS drug cocaine 18991842 We found that the composition of AP 1 transcription complexes and expression levels of AP 1 complexes, and several transcription factors, neurotransmitter receptors as well as intracellular signaling molecules following repeated cocaine administration are altered in Fos deficient brains. FOS drug cocaine 18991842 These findings suggest that c Fos expressed in D1 receptor bearing neurons mediates cocaine induced persistent changes. FOS drug psychedelics 18973603 Acute and sensitized response to 3,4 methylenedioxymethamphetamine in rats: different behavioral profiles reflected in different patterns of Fos expression. FOS drug psychedelics 18973603 Acute MDMA exposure produced a dose dependent increase in locomotion in the peripheral zone of the open field that was related to an increase in Fos expression in the ventromedial shell of the nucleus accumbens, ventral pallidum, several hypothalamic nuclei and rhomboid thalamic nucleus. FOS drug cocaine 18938216 To understand intracellular mechanisms contributing to cocaine induced neuroadaptations, we previously examined the role of the immediate early gene Fos using a mouse in which Fos is disrupted primarily in D1 receptor expressing neurons in the brain. FOS drug amphetamine 18834549 Amphetamine and pseudoephedrine cross tolerance measured by c Fos protein expression in brains of chronically treated rats. FOS drug amphetamine 18834549 (ii) In animals chronically treated with amphetamine or pseudoephedrine the acute c Fos response to pseudoephedrine and amphetamine was reduced respectively as compared to naïve animals indicating cross tolerance for the two drugs. FOS drug opioid 18831893 In the VTA, morphine and footshock had an interactive effect on the increase in Fos expression. FOS drug opioid 18831893 Inhibition of the CeA decreased Fos expression in the BNSTv regardless of drug experience, whereas in the VTA this effect only occurred in morphine treated rats. FOS drug opioid 18823165 A morphine paired environment alters c Fos expression in the forebrain of rats displaying conditioned place preference or aversion. FOS addiction aversion 18823165 A morphine paired environment alters c Fos expression in the forebrain of rats displaying conditioned place preference or aversion. FOS addiction reward 18823165 Compared with the control group, the CPP and CPA groups showed a significant increase of c Fos expression in the dorsomedial striatum, central medial nucleus of the thalamus, and the basolateral amygdala. FOS drug cocaine 18822274 Effects of dopamine and NMDA receptors on cocaine induced Fos expression in the striatum of Fischer rats. FOS drug cocaine 18822274 In this study, we show that a single cocaine administration (30 mg/kg) time dependently increases ERK phosphorylation, c Fos and FosB protein expression, and MKP 1 phosphorylation (p MKP 1), in the caudate putamen (CPu) and nucleus accumbens (NAc) of Fischer rats. FOS drug cocaine 18822274 In the CPu, 1 h after cocaine injection, the increase in c Fos and FosB protein expressions is totally abolished by pre administration of DA D1 receptor antagonist, SCH23390. FOS drug cocaine 18822274 In the NAc, SCH23390 also inhibits cocaine induced c Fos protein expression. FOS drug cocaine 18822274 The pre treatment of NMDA receptor antagonist, MK801, partially reduces cocaine activated c Fos protein expression in the CPu. FOS drug alcohol 18815268 Using c Fos expression as a high resolution marker of neuronal activation, congenic mice demonstrated significantly less neuronal activity associated with ethanol withdrawal than background strain mice in the substantia nigra pars reticulata (SNr), subthalamic nucleus (STN), rostromedial lateral globus pallidus, and ventral pallidum.

FOS addiction addiction 18789904 Induction of immediate early genes (IEG), such as c Fos or Egr 1, is used to identify brain areas that become activated in response to various stimuli, including addictive drugs. FOS drug opioid 18772347 Spinal administration of an EphB receptor blocking reagent EphB2 Fc prevents and/or suppresses behavioral responses to morphine withdrawal and associated induction of c Fos and depletion of calcitonin gene related peptide.

FOS addiction relapse 18755245 Effects of pharmacological stressors on c fos and CRF mRNA in mouse brain: relationship to alcohol seeking. FOS drug alcohol 18755245 The purpose of the present experiment is to determine if these differential effects of yohimbine and FG 7142 on regional c fos and CRF mRNA expression generalize to another animal commonly used in alcohol research, the C57 BL/6J mouse. FOS addiction relapse 18755245 The selective induction of c fos in the NACs, BLA and CeA of mice and rats by yohimbine offers further support for the idea that activation of these structures participates in reinstatement induced by such stressors. FOS addiction reward 18722478 In the limbic system, Fos positive neurons were examined following retrieval of the MA CPP memory. FOS addiction reward 18722478 Moreover, enhanced Fos expressions were found in the medial prefrontal cortex and the core of the nucleus accumbens after reactivation of the MA CPP memory. FOS drug alcohol 18692030 Ethanol induced alterations of c Fos immunoreactivity in specific limbic brain regions following ethanol discrimination training. FOS drug alcohol 18692030 To accomplish this goal, immunohistochemistry was used to assess the effects of ethanol (2 g/kg) on c Fos immunoreactivity (Fos IR). FOS drug alcohol 18692030 Comparisons in ethanol induced Fos IR were made between a group of rats that was trained to discriminate the stimulus properties of ethanol (2 g/kg, IG) from water (IG) and a drug/behavior matched control group that did not receive differential reinforcement for lever selection, which precluded acquisition of discriminative stimulus control by ethanol.

FOS drug alcohol 18692030 In some brain regions discrimination training had no effect on ethanol induced Fos IR changes (caudate putamen, bed nucleus of the stria terminalis, and CA1 region of the hippocampus). FOS drug alcohol 18692030 In contrast, discrimination training altered the pattern of ethanol induced Fos IR in the nucleus accumbens (core), medial septum, and the hippocampus (dentate and CA3). FOS drug alcohol 18692030 These results indicate that having behavior under the stimulus control of ethanol can change ethanol induced Fos IR in some brain regions. FOS drug cocaine 18655797 We found that Fos expression in LH orexin neurons varied in proportion to preference for morphine, cocaine or food. FOS drug opioid 18655797 We found that Fos expression in LH orexin neurons varied in proportion to preference for morphine, cocaine or food. FOS drug opioid 18655797 Recent studies showed that LH orexin neurons that project to ventral tegmental area (VTA) have greater Fos induction in association with elevated morphine preference during protracted withdrawal than non VTA projecting orexin neurons, indicating that the VTA is an important site of action for orexin's role in reward processing.

FOS addiction withdrawal 18655205 injection of the sigma 1 receptor agonists PRE 084 (PRE) or carbetapentane (CAR) significantly decreased tail flick latency (TFL) and increased the frequency of paw withdrawal responses to mechanical stimulation (von Frey filament, 0.6 g) as well as the amount of Fos expression in the spinal cord dorsal horn induced by noxious paw pinch stimulation. FOS drug cocaine 18651175 Finally, increased Fos activation in the extended amygdala and NTS is associated with the enhanced preference for drugs and decreased preference for natural rewards observed during protracted abstinence from opiates and cocaine, indicating that these areas are involved in the altered reward processing associated with addiction.

FOS drug psychedelics 18633827 Analysis of neural activation across 39 brain regions using Fos immunohistochemistry showed the following results: (1) VEHICLE SOCIAL and VEHICLE ALONE groups did not differ in Fos expression, indicating that a social context per se did not affect Fos expression, (2) MDMA treated groups showed significantly increased Fos expression relative to VEHICLE treated groups in 30 brain regions, (3) the MDMA SOCIAL group showed augmented Fos expression relative to the MDMA ALONE group in six brain regions including the caudate putamen (medial), medial preoptic area, paraventricular thalamic nucleus, central amygdala, ventromedial hypothalamic nucleus, and the medial amygdala (posterodorsal), and (4) the MDMA SOCIAL group (but not the MDMA ALONE group) showed augmented Fos expression relative to the VEHICLE groups in the nucleus accumbens, ventral tegmental area and periaqueductal grey. FOS drug amphetamine 18632938 Delta FosB mediates epigenetic desensitization of the c fos gene after chronic amphetamine exposure. FOS drug amphetamine 18632938 We show that accumulation of DeltaFosB in striatum after chronic amphetamine treatment desensitizes c fos mRNA induction to a subsequent drug dose. FOS drug amphetamine 18632938 Accordingly, local knock out of HDAC1 in striatum abolishes amphetamine induced desensitization of the c fos gene. FOS drug amphetamine 18632938 In concert, chronic amphetamine increases histone H3 methylation on the c fos promoter, a chromatin modification also known to repress gene activity, as well as expression levels of the H3 histone methyltransferase, KMT1A (lysine methyltransferase 1A, formerly SUV39H1).

FOS addiction relapse 18539009 This study investigated the effects of the AMPA/Kainate receptor antagonist, NBQX, on cue elicited cocaine seeking behavior and concomitant changes in Fos protein expression. FOS drug cocaine 18539009 NBQX markedly attenuated cue elicited cocaine seeking behavior relative to vehicle pretreatment in the No Extinction group and also decreased cue elicited Fos protein expression in a region specific manner in the anterior cingulate and orbitofrontal cortices, basolateral amygdala, nucleus accumbens core, and dorsal caudate putamen, suggesting involvement of AMPA glutamate systems in specific subregions of the neuronal circuitry activated by cocaine cues.

FOS drug cocaine 18495107 Inhibition of dopamine release by isoliquiritigenin resulted in attenuation of the expression of c Fos, an immediately early gene induced by cocaine. FOS drug cannabinoid 18493584 In addition, peripheral and central cannabinoid administration similarly induced c Fos activation in brain sites suggesting mediation via motivational dopaminergic circuitry. FOS drug cocaine 18488248 Using an animal model of relapse to cocaine seeking, the present study investigated the expression patterns of three different activity related genes (c fos, zif/268, and arc) in cortical and striatal brain regions implicated in compulsive drug seeking in order to determine the neuroadaptations that occur during context induced relapse following brief or prolonged abstinence from cocaine self administration.

FOS drug cocaine 18488248 Re exposure to the environment previously associated with cocaine self administration following 22 h or 15 days of abstinence produced a significant increase in zif/268 and arc, but not c fos mRNA, in the caudate putamen and nucleus accumbens. FOS drug opioid 18485622 Morphine and methadone pre exposures differently modify brain regional Fos protein expression and locomotor activity responses to morphine challenge in the rat. FOS drug opioid 18485622 We compared the effects of repeated daily and every other day pre exposure of rats to s.c. morphine and methadone on locomotor activity and CNS neuronal activation (as assessed by Fos immunohistochemistry) responses to s.c. morphine challenge given 2 weeks after the completion of the pretreatment. FOS drug opioid 18485622 Dorsomedial striatum and basolateral amygdaloid nucleus showed robust morphine induced Fos protein induction that was unaffected by the pretreatments tested. FOS drug opioid 18485622 Centrolateral striatum, shell and core of the nucleus accumbens, paraventricular thalamic nucleus and some layers of motor and somatosensory cortices showed but negligible Fos protein induction in drug naive rats; this response was markedly enhanced by morphine pretreatment only, which effect might be related to the emergence of opiate addiction.

FOS drug opioid 18466961 Fos expression was also increased after 1 and 14 days of abstinence, but at 14 days this increase was response independent (i.e., it occurred in both the rats with a history of heroin self administration and in the yoked controls). FOS drug cocaine 18463628 Finally, basal levels of Delta Fos B, a transcription factor known to be increased by sustained activation of striatal neurons, are higher in the striatum of EE compared to SE mice and repeated administration of cocaine increases Delta Fos B levels in SE mice but decreases them in EE mice. FOS addiction withdrawal 18423425 Withdrawal was accompanied by an increase in c Fos expression in the Acb shell (AcbSh), which was reduced by SB 334867 but had no effect on the VTA or the LC. FOS drug opioid 18423425 Morphine withdrawal increased c Fos expression in the dorsomedial (DMH) and perifornical (PFA) regions but not in the lateral region of the LH (LLH). FOS addiction withdrawal 18423425 Morphine withdrawal increased c Fos expression in the dorsomedial (DMH) and perifornical (PFA) regions but not in the lateral region of the LH (LLH). FOS drug alcohol 18412612 induced expression of the marker genes c fos and egr 1 in brain regions associated with both rewarding and stressful ethanol actions. FOS drug alcohol 18412612 Under non dependent conditions, ethanol induced c fos expression was generally not affected by MEK inhibition, with the exception of the medial amygdala (MeA). FOS drug alcohol 18412612 In contrast, following a history of dependence, a markedly suppressed c fos response to acute ethanol was found in the medial pre frontal/orbitofrontal cortex (OFC), nucleus accumbens shell (AcbSh) and paraventricular nucleus (PVN). FOS addiction dependence 18412612 In contrast, following a history of dependence, a markedly suppressed c fos response to acute ethanol was found in the medial pre frontal/orbitofrontal cortex (OFC), nucleus accumbens shell (AcbSh) and paraventricular nucleus (PVN). FOS drug cocaine 18396266 The rate of intravenous cocaine administration alters c fos mRNA expression and the temporal dynamics of dopamine, but not glutamate, overflow in the striatum. FOS drug cocaine 18396266 In contrast, although peak levels of dopamine were unaffected by infusion rate, dopamine levels increased more rapidly when cocaine was administered over 5 versus 100 s. Moreover, c fos mRNA expression in the region of the striatum sampled was greater when cocaine was administered rapidly than when given slowly. FOS drug cocaine 18355967 Following a single injection of cocaine, locomotion increased similarly in both the A FOS expressing and littermate controls.

FOS drug cocaine 18355967 A FOS expression did not change gene expression in the basal state or 4 h following cocaine treatment relative to controls. FOS drug cocaine 18355967 However, 24 h after an acute cocaine treatment, 84 genes were identified that were differentially expressed between the A FOS and control mice. FOS drug opioid 18349210 Suppression of noxious induced c fos expression in the rat lumbar spinal cord by isoflurane alone or combined with fentanyl. FOS drug opioid 18349210 Since the anesthetic mechanisms differ between inhaled anesthetics and opioids, we evaluated the differential effects of isoflurane and fentanyl on c fos expression at the lumbar level as a measure of nociceptive information transfer during general anesthesia. FOS drug opioid 18349210 The main suppressive effects on lumbar c fos expression of isoflurane were observed in the superficial lamina II (P = 0.02), whereas fentanyl showed the strongest effects in lamina V (P = 0.05). FOS drug opioid 18349210 This study demonstrates that the NIWR model combined with spinal Fos immunoreactivity is a suitable and useful model for evaluating the differential effects of inhaled anesthetics and opioids on nociceptive information transfer during general anesthesia.

FOS addiction sensitization 18347780 The increase in c fos positive nuclei and shift in the distribution of optical density observed in the nucleus accumbens core suggests recruitment of a new population of neurons during expression of sensitization. FOS drug nicotine 18337407 Significantly, although chronic nicotine SA did not affect total c Fos expression induced by mFSS in pcPVN CRF(+) neurons, the majority of the new CRF(+)/AVP(+) population was activated by this heterotypic stressor. FOS drug cocaine 18311559 Rats self administered cocaine or received yoked saline for 2 h/day for 10 days followed by 22 h or 2 weeks of abstinence when they were re exposed to the self administration chamber with or without levers available to press for 1 h. Brains were harvested and sections through the prefrontal cortex were processed for in situ hybridization using radioactive oligonucleotide probes encoding c fos, zif/268, arc, and bdnf.

FOS drug cocaine 18310906 It has been shown that repeated injections of cocaine produce an increase in locomotor activity, the expression of the immediate early gene, c fos, and the release of dopamine (DA) in the nucleus accumbens (NAc), which is one of the main dopaminergic terminal areas.

FOS drug opioid 18184800 In contrast to PENK, no association was detected between PDYN genotype (68 bp repeat element containing one to four copies of AP 1 binding sites in the promoter region) and heroin abuse, although there was a clear functional association with striatal PDYN mRNA expression: an increased number of inducible repeats (three and four) correlated with higher PDYN levels than adult or fetal subjects with noninducible (one and two) alleles. FOS drug amphetamine 18184321 To test whether the behavioral phenotype is also accompanied by similar neuroplastic adaptations, the present study evaluated changes in Fos and FosB/DeltaFosB transcription factors induced in the brain of C57BL/6J mice behaviorally sensitized by repeated amphetamine or repeated restraint stress.

FOS drug opioid 17015856 Opioid modulation of Fos protein expression and olfactory circuitry plays a pivotal role in what neonates remember. FOS drug opioid 17015856 Experiment 1 assessed post training opioid modulation of Fos protein expression within olfactory circuitry (olfactory bulb, piriform cortex, amygdala). FOS drug opioid 17015856 Post training opioid receptor antagonism (odor aversion) prevented the learning induced changes in the anterior piriform cortex and also induced significant changes in Fos protein expression in the central nucleus of the amygdala.

FOS addiction withdrawal 16935424 Naloxone challenge to morphine treated animals precipitated an intense withdrawal syndrome that depleted CGRP immunoreactivity and increased Fos expression in the dorsal horn. FOS addiction withdrawal 16935424 The Fos response primarily occurred in neurons that expressed CGRP receptor component protein (RCP) suggesting CGRP activity contributes to neuronal activation during precipitated withdrawal.

FOS drug cocaine 16930414 In the present study, we found cocaine induced Fos expression in nucleus accumbens, but not caudate putamen, was enhanced 1 and 6 months after repeated drug administration in locomotor activity chambers. FOS drug cocaine 16930414 In contrast, cocaine induced Fos expression was absent altogether in nucleus accumbens and unaltered in caudate putamen 1 month after repeated cocaine administration in the home cage. FOS drug cocaine 16930414 Bilateral infusions of the GABA agonists baclofen and muscimol (1 microg/side) into nucleus accumbens of sensitized rats blocked cocaine induced Fos expression and locomotor activity.

FOS drug alcohol 16750178 Lack of evidence of a role for the neurosteroid allopregnanolone in ethanol induced reward and c fos expression in DBA/2 mice. FOS addiction reward 16750178 Lack of evidence of a role for the neurosteroid allopregnanolone in ethanol induced reward and c fos expression in DBA/2 mice. FOS drug alcohol 16750178 induced conditioned place preference and c fos expression in DBA/2 mice; a strain known to be particularly sensitive to ethanol. FOS drug alcohol 16750178 Ethanol administration induced a clear conditioned place preference and widespread c fos expression, with elements of the extended amygdala, Edinger Westphal nucleus and paraventricular nucleus being especially sensitive. FOS drug alcohol 16750178 However, despite an approximately 99% decrease in whole brain allopregnanolone content, finasteride pretreatment had remarkably little effect on either ethanol induced conditioned place preference or ethanol induced c fos expression. FOS drug alcohol 16750178 Thus, aside from a general stimulatory effect on c fos expression in the ventral tegmental area, and generally mild depression of locomotor activity, no other effects of finasteride or interaction with ethanol effects were identifiable. FOS drug amphetamine 16713106 Habituation to the test cage influences amphetamine induced locomotion and Fos expression and increases FosB/DeltaFosB like immunoreactivity in mice. FOS drug amphetamine 16713106 The present experiments tested the effects of repeated exposure to a test cage (1 h daily for four consecutive days) on amphetamine induced locomotion and Fos expression as well as on FosB/DeltaFosB like immunoreactivity in mice of the C57BL/6J and DBA/2J inbred strains that differ for the response to amphetamine, stress and novelty. FOS drug amphetamine 16713106 Moreover, previous habituation to the test cage reduced the locomotor response to a low dose of amphetamine only in DBA mice while it reduced amphetamine induced Fos expression in medial prefrontal cortex, dorsal caudate and the accumbens shell of mice of the C57 strain. FOS drug amphetamine 16713106 Moreover, they suggest that the procedure of daily familiarization influences the pattern of brain Fos expression induced by amphetamine.

FOS drug nicotine 16631212 In mice neither 2 nor 7 week oral nicotine treatment induced expression of long lived DeltaFosB isoforms although during the treatment in the NAcc FosB/DeltaFosB expression was increased as was c Fos in the CPu. FOS drug nicotine 16631212 In rats given nicotine subcutaneously once daily for 5days FosB/DeltaFosB expression was elevated in the NAcc still after 24 h withdrawal suggesting accumulation of DeltaFosB but in the CPu neither FosB/DeltaFosB nor c Fos expression was altered. FOS addiction withdrawal 16631212 In rats given nicotine subcutaneously once daily for 5days FosB/DeltaFosB expression was elevated in the NAcc still after 24 h withdrawal suggesting accumulation of DeltaFosB but in the CPu neither FosB/DeltaFosB nor c Fos expression was altered. FOS drug nicotine 16631212 However, in mice given nicotine via drinking fluid although striatal fosB and c fos were activated by nicotine even after 7 week treatment no evidence of accumulation of long lived DeltaFosB was found suggesting perhaps a species difference or more likely a role for the manner of administration. FOS drug cocaine 16580740 Several reports show cocaine induced c fos expression particularly in the intermediate zone after 14, but not 2, drug free days following repeated cocaine administration, suggesting that this region may be involved in sensitization and particularly in the later phase of expression, versus the earlier phase of sensitization.

FOS drug cocaine 16395306 Rats trained on a running wheel under the influence of cocaine for 4 days subsequently displayed greater c fos induction by cocaine than untrained controls. FOS drug cocaine 16395306 Wheel training was performed after injection of cocaine (25 mg/kg) or vehicle, and c fos induction by a cocaine challenge was measured 24 h later. FOS drug cocaine 16395306 Rats that trained under cocaine (but not vehicle) showed a greater c fos response in the striatum compared to locked wheel controls. FOS addiction withdrawal 16385558 Attenuated expression of withdrawal behaviors correlated with decreased c Fos expression and intracellular signal transduction elements [protein kinase A regulatory subunit II (PKA) and phosphorylated cAMP response element binding protein (pCREB)] in brainstem noradrenergic nuclei. FOS drug alcohol 16385558 In conclusion, our previously reported decreases in c Fos and PKA expression in the NTS following pretreatment with low doses of naltrexone may be partially explained by a greater inhibition of NTS neurons resulting from increased muOR expression in this region.

FOS drug cocaine 16339038 In MSK1 knock out (KO) mice CREB and H3 phosphorylation in response to cocaine (10 mg/kg) were blocked, and induction of c Fos and dynorphin was prevented, whereas the induction of Egr 1 (early growth response 1)/zif268/Krox24 was unaltered. FOS addiction sensitization 16339038 Our results show that MSK1 is a major striatal kinase, downstream from ERK, responsible for the phosphorylation of CREB and H3 and is required specifically for the induction of c Fos and dynorphin as well as for locomotor sensitization.

FOS drug cannabinoid 15812570 Concurrent in situ hybridization analysis of regional c fos and ngfi b expression highlighted areas of the prefrontal cortex and striatum that were recruited in response to both THC administration and task performance. FOS drug cannabinoid 15787710 SR141716 (2 mg/kg) itself had no effect on Fos but pretreatment with SR141716 significantly potentiated restraint induced Fos expression in cingulate, LS and Acb. FOS drug cannabinoid 15787710 Administration of SR141716 prior to the fifth restraint episode resulted in greater potentiation of restraint induced Fos induction than the first; significant increases occurred within all regions of PFC examined, LS and Acb.

FOS drug opioid 15138436 When given in a novel test environment, however, morphine dramatically increased the number of c fos+ striatonigral cells in a dose dependent fashion, and this effect was maintained following repeated treatment. FOS drug opioid 15138436 Unexpectedly, morphine treatment in a novel environment produced a dose dependent reduction in the number of c fos+ striatopallidal cells and c fos+ cells in cingulate cortex, relative to exposure to novelty alone effects that were reversed by repeated morphine treatment.

FOS drug alcohol 14574439 Different pattern of brain c Fos expression following re exposure to ethanol or sucrose self administration environment. FOS drug alcohol 14574439 c Fos protein expression was used as a marker of neuronal activation.Re exposure to ethanol self administration environment after 30 day but not after 24 h abstinence increased the number of Fos positive nuclei in the thalamic paraventricular nucleus, granular insular cortex and medial prefrontal cortex. FOS drug alcohol 14574439 In general, no differences were found in c Fos protein expression between the rats allowed to self administer alcohol and the subjects exposed only to alcohol related stimuli. FOS drug alcohol 14574230 Recently, we found that nuclear RACK1 mediates acute ethanol induction of immediate early gene c fos expression. FOS drug alcohol 14574230 Therefore, we sought to determine the effects of chronic exposure of cells to ethanol on the cellular compartmentalization of RACK1 and on c fos messenger RNA (mRNA) and protein expression. FOS drug alcohol 14574230 Chronic exposure to ethanol did not result in an increase in mRNA or protein levels of c fos. FOS drug alcohol 14574230 Furthermore, acute ethanol exposure did not increase c fos protein levels in cells that were first treated chronically with ethanol. FOS drug alcohol 14574230 However, transduction of exogenous RACK1 expressed as a Tat fusion protein was able to rescue c fos mRNA expression after chronic ethanol exposure. FOS drug alcohol 14574230 Our data suggest that RACK1 nuclear compartmentalization and ethanol induced c fos expression are transient and are desensitized to ethanol during prolonged exposure to high concentrations. FOS drug alcohol 14574230 Our data further suggest that the altered compartmentalization of RACK1 leads to differences in c fos expression upon acute or chronic exposure to ethanol. FOS drug alcohol 14574230 In summary, RACK1 is an important molecular mediator of the acute and chronic actions of ethanol on the expression of c fos.

FOS drug cocaine 14559159 This increase in both c fos and preprodynorphin mRNA levels is attenuated by the noncompetitive NMDA antagonist MK 801 (0.25 mg/kg), suggesting a preferential role for NMDA receptor co activation in cellular events leading to cocaine induced behaviors.

FOS drug opioid 12956728 Naloxone treatment in naive rats induced a slight increase in c Fos immunoreactivity in the central amygdaloid nucleus, the lateral bed nucleus of the stria terminalis and the interstitial nucleus of the posterior limb of the anterior commissure. FOS drug opioid 12956728 In morphine dependent rats, naloxone injection significantly increased the number of c Fos positive neurons in these structures as well as in the majority of the other central extended amygdala components. FOS drug opioid 12956728 Corticotropin releasing factor and methionine enkephakin immunoreactive neurons displayed c Fos immunoreactivity in naive rats after naloxone injection, whereas only enkephalinergic neurons were found to be c Fos positive in morphine dependent rats after naloxone injection.

FOS drug amphetamine 12890524 Environmental context and drug history modulate amphetamine induced c fos mRNA expression in the basal ganglia, central extended amygdala, and associated limbic forebrain. FOS drug amphetamine 12890524 When given in a novel test environment amphetamine produces greater levels of c fos and arc mRNA expression in many brain regions relative to when it is given in the home cage. FOS drug amphetamine 12890524 The purpose of the current study was to determine if environment and drug history interact to influence amphetamine induced c fos mRNA expression. FOS drug amphetamine 12890524 In most brain regions amphetamine given in the Novel environment produced greater c fos mRNA expression than when given it was given at Home, and drug history had no effect on amphetamine induced c fos mRNA expression. FOS drug amphetamine 12890524 However, within the subthalamic nucleus, substantia nigra reticulata, and central nucleus of the amygdala prior experience with amphetamine in the Novel but not Home environment enhanced the effect of an amphetamine challenge injection on c fos mRNA expression. FOS drug amphetamine 12890524 In contrast, there was a decrease in c fos mRNA expression in amphetamine pretreated animals, regardless of environmental context, in the ventral portion of the far caudal striatum. FOS drug amphetamine 12890524 Reexposure to an environment previously paired with amphetamine produced a conditioned increase in c fos mRNA expression in portions of the caudate putamen, the subthalamic nucleus, the nucleus accumbens shell and a conditioned decrease in c fos mRNA expression in the central nucleus of the amygdala.

FOS addiction withdrawal 12814374 Morphine withdrawal precipitated by specific mu, delta or kappa opioid receptor antagonists: a c Fos protein study in the rat central nervous system. FOS drug opioid 12814374 We have recently shown concurrent changes in behavioural responses and c Fos protein expression in the central nervous system in both naive and morphine dependent rats after systemic administration of the opioid antagonist naloxone. FOS drug opioid 12814374 However, because naloxone acts on the three major types of opioid receptors, the present study aimed at determining, in the same animals, both changes in behaviour and c Fos like immunoreactivity after intravenous injection of selective opioid antagonists, such as mu (beta funaltrexamine, 10 mg/kg), delta (naltrindole, 4 mg/kg) or kappa (nor binaltorphimine, 5 mg/kg) opioid receptor antagonists, in naive or morphine dependent rats.

FOS drug cocaine 12786985 In addition, given that STN activity is thought to be influenced by preproenkephalin mRNA containing (ENK+) neurons in the caudate putamen, we also examined whether repeated cocaine treatment alters c fos expression in ENK+ cells. FOS drug cocaine 12786985 We report that: (i) cocaine pretreatment enhances the ability of a cocaine challenge to induce c fos mRNA expression in the STN, and this effect is most robust at challenge doses where behavioural sensitization is observed; (ii) the ability of cocaine to induce c fos in the STN is independent of the ability of cocaine to engage ENK+ cells.

FOS drug cannabinoid 12657697 In vivo THC induced the expression of immediate early genes products (c Fos protein, Zif268, and BDNF mRNAs), and this induction was prevented by an inhibitor of MEK. FOS drug cocaine 12653981 Acute induction of c fos (by 25 mg/kg of cocaine), and the c fos response and dynorphin expression after repeated cocaine treatment (25 mg/kg, 4 days) were assessed as examples for short term and longer term molecular changes, respectively.

FOS drug amphetamine 12641732 The purpose of the present experiment therefore was to determine if the effect of context on amphetamine induced c fos expression is also dose dependent. FOS drug amphetamine 12641732 It was found that: (i) No dose of amphetamine tested (1 10 mg/kg) induced c fos in many ENK+ cells when given at home. FOS drug amphetamine 12641732 (ii) When given in a novel environment low to moderate doses of amphetamine (1 5 mg/kg) induced c fos in substantial numbers of ENK+ cells, but the highest dose examined (10 mg/kg) did not. FOS drug amphetamine 12641732 (iii) Environmental novelty enhanced the ability of low to moderate doses of amphetamine to induce c fos in the STN, but the highest dose of amphetamine induced robust c fos mRNA expression in the STN regardless of context. FOS addiction sensitization 12641732 The results do not support the idea that engaging ENK+ cells, at least as indicated by c fos mRNA expression, is critical to produce robust behavioral sensitization, but do suggest a possible role for the STN.

FOS addiction withdrawal 12499582 Naloxone precipitated morphine withdrawal elicits increases in c fos mRNA expression in restricted regions of the infant rat brain. FOS drug opioid 12499582 We examined the effects of naloxone (2 mg/kg) on c fos mRNA levels in brains of infant and adult rats following repeated treatment with morphine (20 mg/kg, once daily for 5 days). FOS drug opioid 12499582 One hour after a single administration of naloxone (naloxone challenge), an increase in c fos mRNA was observed in the olfactory bulb, hypothalamus and medulla oblongata of infant rats, and in the olfactory bulb and hypothalamus, but not in the medulla oblongata of adult rats. FOS drug opioid 12499582 The c fos mRNA levels returned to control levels 6 h after the naloxone challenge. FOS drug opioid 12499582 When MK 801, a non competitive N methyl D aspartate (NMDA) receptor antagonist, was co administered along with morphine, it inhibited the naloxone induced increases in c fos mRNA levels in infant rats following repeated morphine administration.

FOS drug amphetamine 12492441 In order to distinguish between these possibilities, we studied amphetamine induced c fos immunoreactivity in subregions of rat striatum (patch and matrix compartments of caudate putamen and nucleus accumbens core and shell) in drug naive rats, as well as during long term expression of amphetamine sensitization. FOS addiction sensitization 12492441 In order to distinguish between these possibilities, we studied amphetamine induced c fos immunoreactivity in subregions of rat striatum (patch and matrix compartments of caudate putamen and nucleus accumbens core and shell) in drug naive rats, as well as during long term expression of amphetamine sensitization. FOS drug amphetamine 12492441 We found that, in sensitized animals, amphetamine (1.0 mg/kg) evoked an increase in the ratio of c fos immunopositive cells in striatal patch and matrix compartments, suggesting a preferential involvement of striatal patches in the sensitized response to amphetamine. FOS drug amphetamine 12492441 In drug naive rats, amphetamine (0.5 5.0 mg/kg) dose dependently increased c fos expression in all striatal subregions. FOS drug amphetamine 12492441 Remarkably, the highest dose of amphetamine also evoked an increase in patch : matrix ratio of c fos immunoreactivity. FOS drug amphetamine 12492441 In nucleus accumbens core and shell of amphetamine and saline pretreated animals, amphetamine (1.0 mg/kg) evoked comparable increases in c fos expression. FOS drug amphetamine 12492441 In addition, they suggest that the shift in amphetamine induced c fos expression from striatal matrix to patches in sensitized animals is the consequence of a change in the sensitivity to amphetamine, rather than a long term circuitry reorganization that is exclusive to the sensitized state.

FOS drug alcohol 12482856 Additionally, overexpression of SOD also blunted ethanol induced activation of redox sensitive transcription factors NFkappaB and AP 1 and production of cytokines. FOS drug alcohol 12482856 However, only inhibition of AP 1 with dominant negative TAK1 but not NFkappaB by dominant negative IkappaBalpha significantly blunted ethanol induced increases in CD14, suggesting that AP 1 is important for CD14 transcriptional regulation.

FOS addiction sensitization 12429408 Locomotor sensitization to cocaine is associated with increased Fos expression in the accumbens, but not in the caudate. FOS drug cocaine 12429408 Although Fos immunohistochemistry and c fos in situ hybridization have frequently been used to assess changes in cocaine induced neural activity following prior cocaine exposure, these techniques have rarely been used to examine neural activity in the accumbens of behaviorally sensitized animals. FOS drug cocaine 12429408 In the present experiment, we compared the ability of increasing doses of cocaine to induce Fos in the accumbens and caudate of rats following a treatment procedure (7 once daily injections of 15 mg/kg of cocaine or the saline vehicle) shown to produce robust and persistent (1 week) locomotor sensitization.

FOS addiction withdrawal 12358736 In a second study, the effects of administration of adrenoceptor antagonists on withdrawal induced Fos expression in the PVN were studied. FOS drug opioid 12358736 Pre treatment with alpha1 or alpha2 adrenoceptor antagonists, prazosin (1 mg/kg intraperitoneally) and yohimbine (1 mg/kg intraperitoneally), respectively, 20 min before naloxone administration to morphine dependent rats markedly reduced Fos expression in the PVN.

FOS drug opioid 12225868 In search for the underlying neuronal mechanisms we investigated the influence of stress on morphine induced c fos expression in the brain, and, vice versa, the influence of morphine application on the brain's c fos response to stress. FOS drug opioid 12225868 The stress induced c fos induction was markedly decreased by a moderate (10 mg/kg) dose of morphine. FOS drug opioid 12225868 On the other hand, morphine alone (50 mg/kg) caused only a weak c fos expression in nai;ve animals despite of the rather high dose. FOS drug opioid 12225868 If, however, this morphine dose was applied in the presence of a stressful stimulus, a pronounced c fos expression in the dorsal striatum resulted. FOS drug opioid 12225868 This c fos signal was comparable with the signal seen in morphine sensitized animals.

FOS drug alcohol 12130710 Herein, we characterize the pharmacological and signal transduction mechanisms related to alcohol induced c Fos expression in Edinger Westphal neurons. FOS drug alcohol 12130710 Using immunohistochemistry, we show that pretreatment with gamma aminobutyric acid (GABA) ergic antagonists (4 mg/kg bicuculline and 45 mg/kg pentylenetetrazole) attenuates induction of c Fos expression by alcohol (2.4 g/kg, intraperitoneal). FOS drug alcohol 12130710 In addition, 10 mg/kg 2 (2,3 dihydro 2 methoxy 1,4 benzodioxin 2 yl)4,5 dihydro 1H imidazole (RX 821002), an alpha(2A/D) adrenoceptor antagonist, and 20 mg/kg haloperidol, a dopamine antagonist, also block alcohol induced c Fos expression in Edinger Westphal neurons.

FOS drug opioid 12130710 No effects were seen in alcohol induced c Fos after the pretreatment of 20 mg/kg propranolol (beta adrenoceptor antagonist), 10 mg/kg 2 (2 (4 (2 methoxyphenyl)piperazin 1 yl) ethy) 4,4 dimethyl 1,3 (2H,4H) isoquinolindione dihydrochloride (ARC 239) (alpha(2B/C) adrenoceptor antagonist), or 30 mg/kg naltrexone (opioid antagonist). FOS drug benzodiazepine 12130710 Although positive modulators for the GABA(A) receptor (20 mg/kg 3alpha hydroxy 5alpha pregnan 20 one and 10 30 mg/kg chlordiazepoxide) and opioid receptor (10 mg/kg morphine) produced significant elevations, agonists for alpha(2) adrenoceptors (clonidine) and dopamine receptors (apomorphine) had no effect on Edinger Westphal c Fos expression. FOS drug opioid 12130710 Although positive modulators for the GABA(A) receptor (20 mg/kg 3alpha hydroxy 5alpha pregnan 20 one and 10 30 mg/kg chlordiazepoxide) and opioid receptor (10 mg/kg morphine) produced significant elevations, agonists for alpha(2) adrenoceptors (clonidine) and dopamine receptors (apomorphine) had no effect on Edinger Westphal c Fos expression. FOS drug alcohol 12130710 These findings suggest that alcohol induced c Fos expression in Edinger Westphal results from direct interactions with GABA(A) receptors, which are modified by alpha(2A/D) adrenoceptors and dopamine receptors. FOS drug alcohol 12130710 Also using immunohistochemistry to identify potential intracellular mechanisms associated with alcohol induced c Fos expression in Edinger Westphal, we show time dependent increases in serine 727 phospho signal transducer and activator of transcription 3 (Stat3) but no changes in phospho cAMP response element binding protein and phospho Elk1. FOS drug alcohol 12130710 Finally, blockade of ERK 1/2 phosphorylation with the mitogen activated protein kinase (MEK) 1/2 inhibitor SL327 blocked alcohol induced c Fos expression, suggesting that alcohol induces c Fos in Edinger Westphal neurons through activation of the MEK1/2 ERK1/2 Stat3 pathway. FOS drug alcohol 12130678 We found that nuclear RACK1 is mediating the induction of the immediate early gene c fos expression induced by ethanol. FOS drug alcohol 12130678 First, transduction of full length RACK1 (Tat RACK1) resulted in the induction of c fos expression and enhancement of ethanol activities. FOS drug alcohol 12130678 Third, we identified a dominant negative fragment of RACK1 that inhibited the nuclear compartmentalization of endogenous RACK1 and inhibited ethanol induction of c fos mRNA and protein expression.

FOS drug opioid 10792459 Morphine also induced a higher rate of c fos transcription in the shell of the nucleus accumbens in mutant mice. FOS drug opioid 10792459 These particular behavioural responses to morphine may be associated with the action of the drug on DA release and c fos expression in the shell of the nucleus accumbens of DAT / mice. FOS addiction reward 10780500 The long term adaptive molecular changes in the target neurons of the terminal fields of the mesocorticolimbic DA system, including transcriptional regulation mediated by c fos family gene products on other genes, suggest that the mesolimbic DA projection to the nucleus accumbens is mainly involved in the stimulus reward learning process.

FOS drug opioid 10501478 Whereas dizocilpine maleate partially blocked the morphine induced c Fos expression in the caudate putamen of males, it completely blocked this response in females. FOS drug opioid 10501478 In the caudate putamen, morphine induced c Fos expression was significantly reduced by NPC 17742 (30 min before morphine) in males and completely blocked in females.

FOS drug nicotine 10479714 Acute nicotine increased Fos immunostaining (IS) in the caudate putamen (CPU), the core of nucleus accumbens (NAcc), the cingulate cortex (Cg), and the central nucleus of amygdala (ACe) significantly. FOS drug nicotine 10479714 During nicotine infusion the nicotine induced responses were attenuated in CPU and NAcc, whereas in ACe and Cg Fos immunostaining was increased as in saline infused rats.

FOS addiction relapse 10415707 Cocaine seeking behavior and Fos expression in the amygdala produced by cocaine or a cocaine self administration environment. FOS drug opioid 10415375 Previous studies from this laboratory have demonstrated that acute, systemic administration of morphine results in an induction of the immediate early gene (IEG) proteins, c Fos and Jun B, in the dorsomedial portion of the rat caudate putamen (CPu). FOS drug opioid 10415375 These studies have also shown that morphine can induce c Fos in the central medial nucleus of the thalamus (CM). FOS drug opioid 10415375 As compared to an acute dose of morphine in a naive animal, the induction of c Fos was increased in the dorsolateral CPu following challenge injection at 7 days, but not at 14 days.

FOS drug amphetamine 9889345 Differential decreases in c fos and aldolase C mRNA expression in the rat cerebellum after repeated administration of methamphetamine. FOS drug amphetamine 9889345 The effects of repeated methamphetamine administration on c fos mRNA and aldolase C (Zebrin) mRNA expression in the rat cerebellum were investigated. FOS drug amphetamine 9889345 A single dose of methamphetamine induced c fos mRNA expression in granule and Purkinje cells of both anterior and posterior lobes. FOS drug amphetamine 9889345 Repeated methamphetamine injections reduced methamphetamine induced c fos mRNA signals in the anterior hemisphere and in part of the posterior vermis (lobule VII) and posterior hemisphere. FOS drug amphetamine 9889345 Aldolase C mRNA signals in Purkinje cells decreased only in lobules where methamphetamine induced c fos signals were not reduced (lobules VI and IX). FOS drug amphetamine 9889345 Therefore, differential decreases in c fos mRNA and aldolase C mRNA expression after repeated methamphetamine administration depend upon the localization of Purkinje cells in the cerebellum. FOS drug amphetamine 9889345 Since c fos mRNA and aldolase C mRNA expressions are markers of excitability and the metabolic state of Purkinje cells, respectively, hypofunction of inhibitory Purkinje cells could be induced if methamphetamine is repeatedly injected.

FOS drug alcohol 9835277 Repeated alcohol administration differentially affects c Fos and FosB protein immunoreactivity in DBA/2J mice. FOS drug alcohol 9835277 To identify alcohol responsive brain areas, we have immunohistochemically analyzed expression of c Fos, FosB, and other Fos related antigens in the brain of inbred DBA/2J mice after a single or repeated injection of alcohol (4 g/kg). FOS drug alcohol 9835277 We observed increased expression of c Fos after alcohol administration in the central nucleus of amygdala, paraventricular nuclei of hypothalamus and thalamus, and several other brain areas. FOS drug alcohol 9835277 Repeated administration of alcohol had the tendency to reduce alcohol induced c Fos expression in these areas. FOS drug alcohol 9835277 In contrast to c Fos, FosB expression was found to be elevated significantly higher after repeated than after acute treatment with alcohol in several brain areas, including the shell of nucleus accumbens. FOS drug alcohol 9835277 In contrast to previous c Fos studies, our studies confirm that alcohol administration indeed activates the reward circuits, including the basal ganglia, and suggest that FosB could serve as a more sensitive marker for this activation.

FOS drug cocaine 9813326 Administration of cocaine immediately following social defeat significantly reduced the number of Fos LI nuclei in the DR, PAG and LC. FOS drug cocaine 9813326 Cocaine induced Fos expression returned in the PAG and DR, but not in the LC, 1 week after social stress. FOS drug cocaine 9813326 In conclusion, the present results suggest that the presence of brainstem Fos be related to the ability to express stress induced behavioral sensitization to cocaine. FOS addiction sensitization 9813326 In conclusion, the present results suggest that the presence of brainstem Fos be related to the ability to express stress induced behavioral sensitization to cocaine. FOS drug cocaine 9813294 In contrast to what has been described for c fos and egr 1 immediate early genes, we found that hVH 5 mRNA expression in the NAc and hippocampus was as significant after repeated cocaine injections for 10 days as after a single injection.

FOS drug opioid 9795131 However, rats that were repeatedly pretreated with morphine displayed a marked c fos induction in a few brain areas in response to morphine application. FOS addiction withdrawal 9795131 The c fos signal was transient and not due to a residual withdrawal. FOS drug opioid 9795131 Naloxone precipitated withdrawal led to a more intense c fos expression which also encompassed a greater range of brain areas. FOS addiction withdrawal 9795131 Naloxone precipitated withdrawal led to a more intense c fos expression which also encompassed a greater range of brain areas. FOS drug opioid 9795131 A low morphine dose suppressed the c fos expression nearly completely and was not sufficient to elicit the morphine like expression pattern of c fos. FOS drug opioid 9795131 These areas responded to morphine with an elevated c fos expression only when morphine was repeatedly given previously. FOS addiction sensitization 9795122 In addition to the behavioral sensitization, Amp pretreated rats showed a reduction in the ability of the acute Amp challenge to induce c fos mRNA in the medial prefrontal cortex and neurotensin/neuromedin N (NT/N) mRNA in the nucleus accumbens shell. FOS addiction sensitization 9795122 At doses that blocked the initiation of behavioral sensitization to Amp, clozapine fully and haloperidol partially restored the capacity of acute Amp to induce c fos and NT/N gene expression. FOS addiction relapse 9789813 Post mortem brain maps of c fos related antigens expression showed specific activation in prefrontal cortex, anterior cingulate and nucleus accumbens for both drugs, but of the anterior cingulate cortex only during relapse, suggesting that a subset of the neural network involved in drug self administration is activated during relapse. FOS drug alcohol 9768540 In contrast, studies on alcohol mediated changes in expression of this gene confirm selective hippocampal suppression of basal and experience induced expression of c fos after acute and repeated administration of alcohol. FOS drug alcohol 9768540 This hippocampal suppression is in marked contrast with alcohol mediated induction of c fos expression in other brain areas.

FOS drug alcohol 9756331 Rats in the 'craving' condition showed significantly higher c fos counts than either the 'beer' or 'control' rats in a variety of corticolimbic and brainstem structures, indicating that activation of these regions occurs when a desirable alcoholic beverage is expected but not received.

FOS drug opioid 26735118 The present study has shown that of the large number of neurones showing Fos like immunoreactivity following a single injection of morphine or U50,488H, few were tyrosine hydroxylase positive (dopaminergic) but a larger number were substance Plike immunoreactive. FOS drug cannabinoid 9748483 A comparison of delta 9 THC and anandamide induced c fos expression in the rat forebrain. FOS drug cannabinoid 9748483 delta 9 THC and anandamide caused equally high levels of c fos expression in the paraventricular nucleus of the hypothalamus and the lateral septum. FOS drug cannabinoid 9748483 Both drugs also increased c fos expression in the central nucleus of the amygdala although the effect was greater with delta 9 THC.

FOS drug opioid 9683006 When given acutely, drugs that stimulate kappa opioid receptors (e.g., U 50,488) enhance the locomotor activity of preweanling rats and induce regional increases in Fos immunoreactivity (IR). FOS drug opioid 9683006 The purpose of the present study was two fold: first, to determine whether repeated treatment with a kappa opioid agonist would sensitize the locomotor activity of preweanling rats and, second, to determine whether changes in Fos IR correspond with the occurrence of locomotor sensitization. FOS addiction sensitization 9683006 The purpose of the present study was two fold: first, to determine whether repeated treatment with a kappa opioid agonist would sensitize the locomotor activity of preweanling rats and, second, to determine whether changes in Fos IR correspond with the occurrence of locomotor sensitization. FOS addiction sensitization 9683006 Chronic treatment with U 50,488 depressed Fos expression in a number of brain regions (relative to acutely treated rats); however, these changes in Fos IR did not necessarily coincide with the occurrence of behavioral sensitization. FOS addiction sensitization 9683006 Repeated treatment with U 50,488 did not produce locomotor sensitization in adult rats, so Fos IR was not assessed in this age group.

FOS drug nicotine 9661252 Inducibility of c Fos protein in visuo motor system and limbic structures after acute and repeated administration of nicotine in the rat. FOS drug nicotine 9661252 To identify neuroanatomical substrates affected by nicotine, we have studied its effects after acute and repeated administration through the c Fos protein inducibility in various brain structures. FOS drug nicotine 9661252 Ninety minutes after acute nicotine (0.35 mg/kg, s.c.) the number of c Fos like immunoreactive nuclei was consistently increased in visuo motor structures such as the superior colliculus, the medial terminal nucleus of accessory optic tract, and the nucleus of the optic tract.

FOS addiction sensitization 9655895 Accompanying behavioral sensitization were two postsynaptic neuroadaptive responses: reduction in the ability of Amp to induce c fos gene expression in the infralimbic/ventral prelimbic cortex and NT/N mRNA in the accumbal shell. FOS drug opioid 9592116 We previously reported that withdrawal from morphine induces the expression of Fos, a marker of neuronal activity, in spinal cord neurons, particularly in laminae I and II of the superficial dorsal horn, and that the magnitude of Fos expression is increased in rats with a midthoracic spinal transection. FOS addiction withdrawal 9592116 We previously reported that withdrawal from morphine induces the expression of Fos, a marker of neuronal activity, in spinal cord neurons, particularly in laminae I and II of the superficial dorsal horn, and that the magnitude of Fos expression is increased in rats with a midthoracic spinal transection. FOS addiction withdrawal 9592116 We suggested that loss of withdrawal associated increases in descending inhibitory controls that arise in the brainstem underlie the increased Fos expression after spinal transection.

FOS drug alcohol 9581657 Because the extent that specific regions of brain are critical to the generation of this emotional state is unknown, Fos like immunoreactivity (Fos LI) was used to associate specific regions of the rat brain with the anxiety component of the ethanol withdrawal syndrome exacerbated by an air puff challenge in rats. FOS addiction withdrawal 9581657 Because the extent that specific regions of brain are critical to the generation of this emotional state is unknown, Fos like immunoreactivity (Fos LI) was used to associate specific regions of the rat brain with the anxiety component of the ethanol withdrawal syndrome exacerbated by an air puff challenge in rats. FOS addiction withdrawal 9581657 During withdrawal from either treatment protocol, Fos LI was induced most prominently in forebrain areas, although the midbrain and hindbrain were also represented. FOS addiction withdrawal 9581657 Fos LI expression differed mostly in intensity between the two treatment and withdrawal protocols, with the gastric protocol producing the greatest Fos LI induction in most brain regions. FOS addiction withdrawal 9581657 Furthermore, a comparison of the effects of the air puff challenge versus withdrawal on Fos LI indicated that the behavioral state induced in these two situations share functional neuroanatomical features. FOS addiction withdrawal 9581657 Some regions such as the accumbens core, medial septum, subregions of the amygdala, hippocampus, substantia nigra, and cerebellum exhibited little Fos LI during withdrawal and also did not exhibit strong increases after the addition of the air puff challenge. FOS drug alcohol 9581657 However, other regions such as the cerebral cortex (medial prefrontal, frontal, cingulate and ventrolateral orbital, claustrum, and tenia tecta), hypothalamus, and locus ceoruleus exhibited Fos LI at levels higher than that seen after either the ethanol withdrawal or puff challenge alone.

FOS drug opioid 9334431 To characterize how systemic morphine induces Fos protein in dorsomedial striatum and nucleus accumbens (NAc), we examined the role of receptors in striatum, substantia nigra (SN), and ventral tegmental area (VTA). FOS drug opioid 9334431 Morphine injected into medial SN or into VTA of awake rats induced Fos in neurons in ipsilateral dorsomedial striatum and NAc.

FOS drug cocaine 9294222 FosB mutant mice: loss of chronic cocaine induction of Fos related proteins and heightened sensitivity to cocaine's psychomotor and rewarding effects. FOS drug cocaine 9294222 We previously have shown that long lasting Fos related proteins of 35 37 kDa are induced in the striatum by chronic cocaine administration. FOS drug cocaine 9294222 The striatum of these mice completely lacked basal levels of the 35 to 37 kDa Fos related proteins as well as their induction by chronic cocaine administration. FOS drug cocaine 9294222 These results establish the long lasting Fos related proteins as products of the fosB gene (specifically DeltaFosB isoforms) and suggest that transcriptional regulation by fosB gene products plays a critical role in cocaine induced behavioral responses. FOS drug cocaine 9294222 This finding demonstrates that a Fos family member protein plays a functional role in behavioral responses to drugs of abuse and implicates fosB gene products as important determinants of cocaine abuse.

FOS addiction withdrawal 9284361 Selective withdrawal of morphine from peripheral opioid receptors by naloxone methiodide did not induce Fos like immunoreactivity in the lumbar spinal cord greater than that recorded in nonwithdrawing rats. FOS drug opioid 9284361 However, intrathecal injection of naloxone methiodide increased Fos like immunoreactivity in laminae I/II and the ventral horn to a greater extent than did subcutaneous injection of naloxone. FOS addiction withdrawal 9284361 We hypothesize that the increased Fos expression after systemic withdrawal in spinally transected rats results from a loss of descending inhibitory control that is activated during withdrawal. FOS addiction withdrawal 9284361 The increase in withdrawal induced Fos like immunoreactivity after rhizotomy may be secondary to loss of inhibitory controls exerted by large diameter primary afferents or to deafferentation induced reorganization in the dorsal horn.

FOS drug opioid 8883853 U50,488H administration resulted in higher numbers of Fos LI stained neurons compared to morphine in most regions other than the nucleus accumbens and interpeduncular nucleus. FOS drug opioid 8883853 Morphine and DAMGO produced significantly higher numbers of Fos LI neurons in the nucleus accumbens shell region than U50,488H, which may reflect the more powerful reinforcing/rewarding effects of mu receptor agonists.

FOS drug opioid 8843097 The specific mu receptor opioid agonist, Tyr, D Ala2, Gly, N Me Phe4, Gly ol5 (DAMGO), was found to increase AP 1 and NF kappa B activity in primary cultures of neurons from rat cerebral cortex. FOS drug opioid 8843097 Acute (2 h, 4 h) and long term (72 h) treatment with DAMGO time dependently increased the DNA binding activity of both AP 1 and NF kappa B and the stimulation could be abolished or inhibited by concurrent incubation with naloxone. FOS drug opioid 8843097 However, acute naloxone precipitated withdrawal did not significantly change AP 1 or NF kappa B activity. FOS addiction withdrawal 8843097 However, acute naloxone precipitated withdrawal did not significantly change AP 1 or NF kappa B activity.

FOS drug nicotine 8593811 The results showed that the magnitude of cFos expression was dependent on the dose of nicotine in all regions studied (P < 0.0006); however, at the two lowest doses, only the NTS and CRH containing region of the PVN expressed cFos, whereas the LC and the rest of the PVN were activated only by higher doses. FOS drug nicotine 8593811 Nicotine also elicited a dose dependent increase in cFos expression in the TH+ neurons of the NTS, with C2 more sensitive than A2. FOS drug nicotine 8593811 Fourth ventricular mecamylamine completely blocked nicotine induced cFos expression throughout the NTS, as well as the PVN.

FOS drug amphetamine 8552240 Repeated amphetamine administration induces a prolonged augmentation of phosphorylated cyclase response element binding protein and Fos related antigen immunoreactivity in rat striatum. FOS drug amphetamine 8552240 Semi quantitative immunocytochemistry was used to investigate the levels of cyclase response element binding protein, phosphorylated cyclase response element binding protein, Fos and Fos related antigen immunoreactivity in the striatum of rats after acute or repeated amphetamine administration. FOS drug amphetamine 8552240 Fos immunoreactivity was significantly induced in the dorsal striatum following acute and repeated amphetamine. FOS drug amphetamine 8552240 Fos immunoreactivity in the core of the nucleus accumbens was significantly increased following repeated amphetamine only. FOS drug amphetamine 8552240 Acute amphetamine induced, and repeated amphetamine further augmented, Fos related antigen immunoreactivity in the dorsal striatum, while not affecting Fos related antigen immunoreactivity in the nucleus accumbens. FOS drug amphetamine 8552240 These data demonstrate that repeated amphetamine administration results in a prolonged induction of phosphorylated cyclase response element binding protein and Fos related antigen immunoreactivity in the dorsal striatum, indicating that alterations in striatal gene expression associated with the development of behavioral sensitization may be mediated, in part, by these transcription factors.

FOS drug cocaine 8974658 Systemic administration of relatively high doses of amphetamine or cocaine induces expression of c fos in the rat striatum and nucleus accumbens. FOS drug amphetamine 8974658 Therefore, it was determined if low doses of amphetamine capable of eliciting reward and sensitization increase levels of c Fos protein in the nucleus accumbens. FOS addiction reward 8974658 Therefore, it was determined if low doses of amphetamine capable of eliciting reward and sensitization increase levels of c Fos protein in the nucleus accumbens. FOS addiction sensitization 8974658 Therefore, it was determined if low doses of amphetamine capable of eliciting reward and sensitization increase levels of c Fos protein in the nucleus accumbens. FOS drug amphetamine 8974658 Amphetamine, 1 mg/kg, stimulated locomotor activity and increased the number of nucleus accumbens cells immunohistochemically positive for c Fos protein to approximately 800 cells per section from a control of approximately 100 cells per section. FOS drug amphetamine 8974658 Since glutamate antagonists modify various responses to amphetamine, it was then determined whether activation of glutamate receptors is involved in the induction of c Fos protein by low doses of amphetamine. FOS drug amphetamine 8974658 When given before amphetamine, both locomotor activity and extent of c fos induction were greater than from amphetamine alone. FOS drug amphetamine 8974658 When given before amphetamine, locomotor activity was completely attenuated, and the extent of c fos induction was greater than from amphetamine alone. FOS drug amphetamine 8974658 We conclude that low doses of amphetamine do increase abundance of c Fos protein in the nucleus accumbens. FOS addiction withdrawal 7476883 Phosphorylation of cyclic AMP response element binding protein and induction of c fos gene expression on withdrawal from chronic treatment with carbachol in NG108 15 cells. FOS addiction withdrawal 7476883 To determine whether this withdrawal induced increase in cAMP modifies gene expression, we studied phosphorylation of the cAMP response element binding protein (CREB) and expression of the c fos gene, known to contain a cAMP response element, in NG108 15 cells after abrupt withdrawal from chronic treatment with carbachol. FOS addiction withdrawal 7476883 In cells treated with carbachol for 48 hr, induction of withdrawal with the muscarinic antagonist atropine led to a small increase in intracellular cAMP concentration but an 11.6 fold increase in the phosphorylation of CREB and a 3.4 fold increase in accumulation of c fos mRNA. FOS addiction withdrawal 7476883 The adenylyl cyclase inhibitor 2',5' dideoxyadenosine, which attenuated the chronic carbachol induced increase in cAMP concentration, prevented the increased phosphorylation of CREB and the enhanced accumulation of c fos mRNA during atropine induced withdrawal. FOS addiction withdrawal 7476883 These results indicate that expression of the c fos gene is induced by the small increments in cAMP concentration that can occur in cells on withdrawal from chronic treatment with drugs such as muscarinic agonists.

FOS drug opioid 8539319 The ability of kappa opioid agonists to modulate dopamine mediated behavior and Fos immunoreactivity was assessed in adult rats. FOS addiction reward 8539319 One hour after CPP testing, rats were killed and Fos immunoreactivity was assessed. FOS drug cocaine 8539319 Rats conditioned with cocaine, but not U 50,488, showed increased Fos activity in the anterior cingulate cortex, piriform cortex, lateral septal area, and olfactory tubercles. FOS drug cocaine 8539319 When considered together, these results suggest that U 50,488 was effective at blocking the unconditioned and conditioned effects of cocaine, as well as cocaine induced neuronal activity (as measured by Fos induction). FOS drug alcohol 7579706 The fall in DG production caused by ethanol and propranolol was accompanied by inhibition of GnRH induced c fos expression, whereas agonist induced luteinizing hormone release was not affected. FOS drug alcohol 7579706 In contrast to their inhibitory actions on GnRH induced early gene expression, neither ethanol nor propranolol affected ET 1 induced c fos expression, or GnRH and ET 1 induced inositol trisphosphate/Ca2+ signaling. FOS addiction sensitization 7637573 The c fos response to D1 receptor activation in adults requires a previous sensitization of dopaminergic receptors by chronic treatment with reserpine or by lesion of the nigro striatal pathway. FOS drug opioid 7637573 The distribution of this transient c fos response corresponded to the early striosomal compartment since it matched with the regions of intense mu opioid and dopamine D1 receptor binding, as assessed by autoradiography performed on adjacent sections.

FOS drug alcohol 7648269 Following intraperitoneal injection of ethanol (16% w/v), Fos immunoreactivity was induced in several rat brain areas including the bed nucleus of the stria terminalis, paraventricular hypothalamic nucleus, the central nucleus of amygdala, Edinger Westphal nucleus, locus coeruleus nucleus and parabrachial nucleus. FOS drug alcohol 7648269 Fos immunoreactivity in the supraoptic nucleus appeared only when a higher concentration of ethanol was injected. FOS drug alcohol 7648269 Repeated administration of ethanol twice daily for 17 or 24 days resulted in a desensitization of Fos immunoreactivity in these nuclei. FOS drug alcohol 7648269 These data suggest that induction of Fos immunoreactivity can be used to determine the sites at which ethanol acts on the brain, and may provide important information about the mechanisms underlying the tolerance and physical dependence of alcohol usage.

FOS drug cocaine 7609608 These data indicate that (1) c fos, zif/268 and preprodynorphin mRNAs are differentially regulated in dorsal striatum, (2) behavioral tolerance results from chronic binges with 10 and 20 mg/kg cocaine and (3) the preprodynorphin genomic response exhibits tolerance to chronic high dose, but not low dose, cocaine binges.

FOS drug amphetamine 7606439 Administration of LiCl induced dense c Fos like immunoreactivity (c FLI) in the nucleus of the solitary tract (NTS) while amphetamine induced only light staining in this area. FOS addiction aversion 7606439 This suggests that the pattern of c Fos expression to a taste CS after conditioning is characteristic of aversion conditioning, in general, and appears not to represent a matching of the conditioned response to specific unconditioned effects of the drug. FOS drug amphetamine 7784961 This study illustrates how a 2 week, twice daily 7.5 mg/kg d amphetamine or saline regimen alters rat brain regional expression of transcription factor genes, including c fos, fos B, jun B, c jun, and zif 268, and seeks potential correlations between those changes and alterations in neurotransmitter levels and behavioral novelty responses.

FOS addiction addiction 1422856 To search for evidence of altered neuronal gene expression in response to exposure to the highly addictive drug nicotine, rat brains were examined by immunocytochemistry for the fos protein after the systemic administration of nicotine. FOS drug nicotine 1422856 The drug was administered as an IV infusion over 1 h At a dose of 2 mg/kg, the most dramatic nicotine induced fos nuclear immunostaining was seen in central visual pathways, including the superficial superior colliculus and the medial terminal nu. FOS drug nicotine 1422856 Notably, many regions with high levels of nicotine binding sites, including the medial habenula, thalamus, substantia nigra, and ventral tegmental area, failed to express the c fos gene with this schedule of nicotine administration. FOS drug nicotine 1422856 A minimal increase in fos immunostaining was seen after a nicotine dose of 0.5 mg/kg, with a much greater response after 1 or 2 mg/kg. FOS drug nicotine 1422856 c fos expression was substantially attenuated in the superficial gray layer of superior colliculus, medial terminal nucleus of the accessory optic tract, and the interpeduncular nucleus by pretreatment with the centrally acting nicotine antagonist mecamylamine, 5 mg/kg IP, but not with the peripherally acting antagonist hexamethonium, 4 mg/kg IP.

FOS drug cocaine 1403102 To understand better the neurobiology of cocaine induced environment specific conditioning, Fos expression was examined in the forebrain of rats exposed to an environment in which they had previously received cocaine. FOS drug cocaine 1403102 Consistent with its stimulant actions, cocaine produced an increase in locomotion that was accompanied by an increase in Fos expression within specific limbic regions (cingulate cortex, claustrum, piriform cortex, lateral septal nucleus, paraventricular nucleus of the thalamus, lateral habenula, and amygdala) as well as the basal ganglia (dorsomedial striatum and nucleus accumbens).

FOS drug cocaine 1631058 As would be expected from the RNA data and immunohistochemistry, acute cocaine administration increased AP 1 binding activity in the NAc, an effect that reverted completely to control levels within 8 12 hr. FOS drug cocaine 1631058 In contrast, AP 1 binding activity in the NAc of animals treated chronically with cocaine remained elevated at acute levels 18 hr after the last chronic injection, a time at which c fos and c jun mRNA levels and Fos like immunoreactivity had returned to control values.

BDNF drug alcohol 32063838 Deficiencies in BDNF levels increased ethanol self administration in rats. BDNF drug alcohol 32063838 Further, BDNF triggers important anti inflammatory effects in the brain, and this could be one of the mechanisms by which BDNF reduces chronic alcohol intake. BDNF drug alcohol 32063838 We hypothesize that ethanol exposure during adolescence decreases the expression of α MSH and hence MC4R signaling in the hippocampus, leading to a lower BDNF activity that causes dramatic changes in the brain (e.g., neuroinflammation and decreased neurogenesis) that predispose to maintain alcohol abuse until adulthood. BDNF drug alcohol 32063838 The activation of MC4R either by α MSH or by synthetic agonist peptides can induce the expression of BDNF, which would trigger several processes that lead to lower alcohol consumption.

BDNF drug nicotine 30815604 The genotypic proportion of the polymorphism responsible for BDNF Val66Met was determined in 148 participants including 88 current smokers, 21 former smokers, and 39 never smokers, and Fisher's exact test was used to investigate the relationship between this polymorphism and smoking cessation and initiation as well as the association between the genotypes of current smokers with a heavy smoking index (HSI) and the age of smoking initiation. BDNF drug nicotine 30815604 Moreover, the 5 HTTLPR polymorphism was associated with the age of smoking initiation in current smokers carrying the BDNF Met allele, in both the whole study sample (P = 0.041) and the male subgroup (P = 0.041). BDNF drug nicotine 30815604 On the other hand, no association was observed between the BDNF Val66Met polymorphism, either alone or in combination with the 5 HTTLPR polymorphism, and the age of smoking cessation. BDNF drug nicotine 30815604 Finally, no independent effects of the BDNF Val66Met genotype on the age of smoking initiation were detected. BDNF drug nicotine 30815604 This pilot study provides preliminary findings regarding the influence of BDNF Val66Met on smoking phenotypes and the interacting effect of 5 HTTLPR on the association between BDNF Val66Met and smoking phenotypes in Japanese participants.

BDNF drug cocaine 30738029 For biochemical determinations, MDPV (1.5 mg/kg) or cocaine (15 mg/kg) were administered acutely or repeatedly, and BDNF, D3R and G9a transcription levels as well as pro and mature BDNF protein levels were determined. BDNF drug cocaine 30738029 Interestingly, such decline was involved in the development of locomotor sensitization, thus the pretreatment with 7,8 dihydroxyflavone (10 mg/kg), a TrkB agonist, blocked the development of sensitization to MDPV but not to cocaine, for which no changes in the BDNF TrkB signaling pathway were observed at early withdrawal.

BDNF drug nicotine 30659208 We aimed to explore the relationships between smoking, cognitive performance and BDNF in a normal Chinese Han population. BDNF drug nicotine 30659208 We recruited 628 male healthy subjects, inducing 322 smokers and 306 nonsmokers, and genotyped them the BDNF Val66Met polymorphism. BDNF drug nicotine 30659208 Of these, we assessed 114 smokers and 98 nonsmokers on the repeatable battery for the assessment of neuropsychological status (RBANS), and 103 smokers and 89 nonsmokers on serum BDNF levels. BDNF drug nicotine 30659208 BDNF levels among the smokers who were Val allele carriers were correlated with the degree of cognitive impairments, especially attention, as well as with the carbon monoxide concentrations. BDNF drug nicotine 30659208 The association between higher BDNF levels and cognitive impairment, mainly attention in smokers appears to be dependent on the BDNF Val66Met polymorphism. BDNF drug nicotine 30616127 Current smokers had significantly higher mean BDNF concentrations than never smokers. BDNF drug nicotine 30616127 In this study, higher BMI and smoking were associated with higher concentrations of serum BDNF, while nutrients that have been linked to depression were not associated with BDNF concentrations among Japanese workers.

BDNF drug alcohol 30056122 The neurotrophin Brain Derived Neurotrophic Factor (BDNF) has been implicated in a number of neuropsychiatric disorders, including alcohol use disorder. BDNF drug alcohol 30056122 Studies have shown that BDNF activity in cortical regions, such as the medial prefrontal cortex (mPFC) mediates various ethanol related behaviors. BDNF drug alcohol 30056122 We previously reported a significant down regulation in Bdnf mRNA in mPFC following chronic ethanol exposure compared to control mice. BDNF drug alcohol 30056122 The present study was conducted to extend these findings by examining whether chronic ethanol treatment reduces BDNF protein expression in mPFC and whether reversing this deficit via direct injection of BDNF or viral mediated overexpression of BDNF in mPFC alters voluntary ethanol consumption in dependent and nondependent mice. BDNF drug alcohol 30056122 Results indicated that CIE treatment significantly increased ethanol intake and this was accompanied by a significant decrease in BDNF protein in mPFC that lasted at least 72 h after CIE exposure. BDNF drug alcohol 30056122 In a separate study, once dependence related increased drinking was established, bilateral infusion of BDNF (0, 0.25, 0.50 μg) into mPFC significantly decreased ethanol intake in a dose related manner in dependent mice but did not affect moderate drinking in nondependent mice.

BDNF drug cocaine 29859319 Cocaine mediated activation of microglia and microglial MeCP2 and BDNF production. BDNF drug cocaine 29859319 Methyl CpG binding protein 2 (MeCP2) binds to the promoter region of BDNF to negatively regulate its expression and cocaine can recruit MeCP2 to alter the expression of genes such as BDNF that are involved in synaptic plasticity. BDNF drug cocaine 29859319 For several decades, BDNF has been implicated in mediating synaptic plasticity associated with cocaine abuse, and most studies report that neurons are the primary source for BDNF production in the brain. BDNF drug cocaine 29859319 The current study assessed the effects of intravenous cocaine self administration on microglial activation, and MeCP2 and BDNF expression in reward regions of the brain in vivo, as well as determined specific effects of cocaine exposure on MeCP2 and BDNF expression in human primary neurons and microglia. BDNF addiction reward 29859319 The current study assessed the effects of intravenous cocaine self administration on microglial activation, and MeCP2 and BDNF expression in reward regions of the brain in vivo, as well as determined specific effects of cocaine exposure on MeCP2 and BDNF expression in human primary neurons and microglia. BDNF drug cocaine 29859319 The results from this study highlight a distinct molecular pathway in microglia through which cocaine increases BDNF, including the phosphorylation of MeCP2 its subsequent translocation from the nucleus to the cytosol, which frees the BDNF promoter and permits its transcriptional activation. BDNF drug cocaine 29859319 Results from these studies show for the first time that cocaine self administration increases microglial activation, and that microglial MeCP2 is a sensitive target of cocaine resulting in increased release of BDNF from microglia, and possibly contributing to cocaine induced synaptic plasticity.

BDNF drug cocaine 29380665 Objectives: Long term abstinence following cocaine exposure up regulates brain derived neurotrophic factor (BDNF) expression in the mesocorticolimbic pathway. BDNF drug cocaine 29380665 Given the increased vulnerability to drug abuse typical of adolescence, we hypothesized that changes in BDNF expression may become manifest early after the end of cocaine treatment in the adolescent brain.Methods: Rats received cocaine injections from postnatal day 28 (PND28) to PND42 and the mesocorticolimbic expression of BDNF was measured by real time PCR and Western blotting at PND43.Results: In the ventral tegmental area, BDNF tropomyosin receptor kinase B (TrΚB) expression and phosphorylation are enhanced while the intracellular signaling is unaltered. BDNF drug cocaine 29380665 To evaluate the role of glutamate on BDNF independent changes, we investigated the expression of the transporter GLT 1 and the activation of the NMDA receptor subunit GluN2B, which were both increased in the PL cortex while reduced in the IL cortex.Conclusions: Our results show that adolescent cocaine exposure modulates BDNF system early after treatment in the mesocorticolimbic pathway, identifying a complex but specific set of changes that could provide clues for treatment.

BDNF drug amphetamine 27287203 We also determined whether PN and/or METH exposure altered protein levels of BDNF (brain derived neurotrophic factor) in the nucleus accumbens, the dorsal striatum, and the prefrontal cortex of adult offspring. BDNF addiction sensitization 27287203 BDNF was of interest because of its role in the development and maintenance of the mesocorticolimbic pathway and its ability to modulate neural processes that contribute to drug abuse, such as sensitization of the dopamine system. BDNF drug amphetamine 27287203 PN and METH exposure produced changes in BDNF protein levels in all three regions, and complex interactions were observed between these two factors. BDNF drug nicotine 27287203 The PN induced alterations in mesocorticolimbic BDNF protein lend further support for the hypothesis that maternal smoking during pregnancy produces alterations in neuronal plasticity that contribute to drug abuse vulnerability.

BDNF addiction intoxication 27154426 While stress alone increased intake during the 12 h binge session, socially defeated rats that received VTA BDNF overexpression exhibited even greater cocaine intake compared to the GFP stressed group. BDNF addiction intoxication 27154426 However, VTA BDNF overexpression alone did not alter binge intake. BDNF drug cocaine 27154426 BDNF expression in the VTA was also positively correlated with total cocaine intake during binge session. BDNF addiction intoxication 27154426 BDNF expression in the VTA was also positively correlated with total cocaine intake during binge session.

BDNF addiction reward 23189980 Specifically, we showed that moderate levels (10%) of ethanol consumption increase BDNF expression within the DLS, and that direct infusion of BDNF into the DLS decreases operant self administration of a 10% ethanol solution. BDNF drug alcohol 23189980 Thus, here, we set out to identify which of these intracellular pathway(s) plays a role in the regulation of ethanol consumption by BDNF. BDNF drug alcohol 23189980 We found that inhibition of the MAPK, but not PLC γ or PI3K, activity blocks the BDNF mediated reduction of ethanol consumption. BDNF drug alcohol 23189980 As activation of the MAPK pathway leads to the initiation of transcription and/or translation events, we tested whether the BDNF mediated reduction of ethanol self administration requires de novo protein synthesis.

BDNF drug cocaine 20810894 Next, the effect of cocaine self administration on specific BDNF exons was assessed; results revealed selectively increased BDNF exon IV containing transcripts in the mPFC. BDNF drug cocaine 20810894 Moreover, there were significant cocaine induced increases in acetylated histone H3 (AcH3) and phospho cAMP response element binding protein (pCREB) association with BDNF promoter IV. BDNF drug cocaine 20810894 In contrast, there was decreased methyl CpG binding protein 2 (MeCP2) association with BDNF promoter IV in the mPFC of rats that previously self administered cocaine. BDNF drug cocaine 20810894 Together, these results indicate that cocaine induced increases in BDNF promoter IV transcript in the mPFC are driven by increased binding of AcH3 and pCREB as well as decreased MeCP2 binding at this BDNF promoter. BDNF drug cocaine 20810894 Collectively, these results indicate that cocaine self administration remodels chromatin in the mPFC, resulting in increased expression of BDNF, which appears to represent a compensatory neuroadaptation that reduces the reinforcing efficacy of cocaine.

BDNF drug alcohol 19864562 We further observed that, in mice, voluntary ethanol intake increases BDNF expression in the dorsal striatum (DS). BDNF drug alcohol 19864562 Here, we determined whether BDNF within the DS regulates ethanol self administration in Long Evans rats trained to self administer a 10% ethanol solution. BDNF drug alcohol 19864562 We observed a greater increase in BDNF expression after ethanol self administration in the dorsolateral striatum (DLS) than in the dorsomedial striatum (DMS). BDNF drug alcohol 19864562 We further found that downregulation of endogenous BDNF using viral mediated siRNA in the DLS, but not in the DMS, significantly increased ethanol self administration. BDNF drug alcohol 19864562 Infusion of exogenous BDNF (0.25 microg/microl/side into the DMS; 0.25 and 0.75 microg/microl/side into the DLS) attenuated responding for ethanol when infused 3 h before the beginning of the self administration session. BDNF drug alcohol 19864562 Although the decrease in ethanol intake was similar in the DLS and DMS, BDNF infused in the DLS, but not in the DMS, induced an early termination of the drinking episode. BDNF drug alcohol 19864562 Furthermore, the action of BDNF in the DLS was specific for ethanol, as infusion of the neurotrophic factor in the DMS, but not DLS, resulted in a reduction of sucrose intake.

BDNF drug alcohol 19453942 Escalating ethanol intake is associated with altered corticostriatal BDNF expression. BDNF drug alcohol 19453942 Previously, we identified brain derived neurotrophic factor (BDNF) in the dorsal striatum as the central mediator of a homeostatic mechanism which is activated by acute alcohol (ethanol) exposure and functions to decrease the sensitivity of rodents to ethanol related behaviors. BDNF drug alcohol 19453942 Previously, we identified brain derived neurotrophic factor (BDNF) in the dorsal striatum as the central mediator of a homeostatic mechanism which is activated by acute alcohol (ethanol) exposure and functions to decrease the sensitivity of rodents to ethanol related behaviors. BDNF drug alcohol 19453942 We hypothesized that extensive exposure to ethanol would result in dysregulation of this BDNF mediated protective mechanism, accompanied by heightened ethanol intake. BDNF drug alcohol 19453942 In this study, we demonstrate that while a single bout of ethanol intake increases BDNF mRNA expression in the dorsal striatum, this effect is no longer observed after 6 weeks of daily ethanol access. BDNF drug alcohol 19453942 Additionally, 6 weeks of ethanol consumption decreases BDNF in the cortex, a main source of BDNF for the striatum. BDNF drug alcohol 19453942 Importantly, these ethanol induced changes in BDNF levels are not ameliorated by 2 weeks' abstinence. BDNF drug alcohol 19453942 Together, these data suggest that the BDNF pathway, which is activated following a single bout of ethanol drinking, breaks down by the end of 6 weeks of access and does not recover its protective function after a 2 week deprivation period. BDNF addiction addiction 19453942 These results suggest that the persistence of altered BDNF signaling may contribute to the inflexibility of addictive behaviors.

BDNF drug cocaine 12099907 Cocaine conditioned mice had increased levels of D3R mRNA and binding in the nucleus accumbens (NAc), and transcripts of brain derived neurotrophic factor (BDNF), a factor controlling D3R expression, in the ventral tegmental area (VTA). BDNF drug cocaine 12099907 Cocaine had no effects on D3R or BDNF genes when administered in home cages. BDNF drug cocaine 12099907 These results demonstrate a modulation of reactivity to cocaine cues by the D3R, the expression of which is elevated in the NAc by the repeated association of drug effects with a particular context, through a BDNF dependent mechanism. BDNF drug opioid 12019333 Here we report that noradrenergic locus ceruleus (LC) neurons of mice with a conditional deletion of BDNF in postnatal brain respond to chronic morphine treatment with a paradoxical downregulation of cAMP mediated excitation and lack of dynamic regulation of TH expression.

BDNF drug alcohol 11532337 Early postnatal ethanol exposure selectively decreases BDNF and truncated TrkB T2 receptor mRNA expression in the rat cerebellum. BDNF drug alcohol 11532337 We believe that the specific ethanol vulnerability, and the timing of this vulnerability result from alterations in the BDNF NT3 interplay. BDNF drug alcohol 11532337 No significant alterations to the expression of TrkC mRNA were found indicating that ethanol exposure appears to act selectively on the BDNF communication system.

TNF drug alcohol 29656414 Symptom severity, alcohol use, cytokine (plasma tumor necrosis factor α and C reactive protein [CRP], transforming growth factor β1 [TGF β1], interleukin 8 [IL 8], IL 10), and plasma BDNF levels were regularly assessed. TNF drug cannabinoid 29607409 The THC+CBD strain was also associated with less desire to smoke, lower levels of subjective drug effects, and lower levels of circulating cytokines (TNF α, IL 6, and IL 1β) immediately after use. TNF drug alcohol 29445009 In vivo and in vitro binge alcohol exposure significantly inhibited the TLR4 MyD88 cytokines TNF α and IL 6, as well as the TLR4 TRIF cytokines/chemokines IFN β, IP 10, and RANTES, in human monocytes, but not TLR3 TRIF induced cytokines/chemokines, as detected by quantitative PCR and ELISA.

TNF addiction relapse 29367619 Independent risk factors for S3 US steatosis in IBD patients at the multivariate logistic regression analysis were: more than 1 IBD relapse per year during disease history (OR 17.3, 95% CI 3.6 84), surgery for IBD (OR 15.1, 95% CI 3.1 73.7) and more extensive intestinal involvement (OR 19.4, 95% CI 3.4 110.9); the ongoing anti Tumor Necrosis Factor alpha (antiTNFα) therapy was the only independent factor which protect toward the presence of altered liver enzymes (OR 0.15, 95% CI 0 0.8, p = 0.02). TNF drug opioid 29135586 In this study, we tried to investigate behavioral hyperalgesia, the expression of proinflammatory cytokines, such as interleukin 1β (IL 1β), interleukin 6 (IL 6), and tumor necrosis factor α (TNF α), and the activation of microglia in the spinal cord and dorsal root ganglion (DRG) in a rat model of surgical plantar incision with or without perioperative fentanyl. TNF drug opioid 29135586 In this study, we tried to investigate behavioral hyperalgesia, the expression of proinflammatory cytokines, such as interleukin 1β (IL 1β), interleukin 6 (IL 6), and tumor necrosis factor α (TNF α), and the activation of microglia in the spinal cord and dorsal root ganglion (DRG) in a rat model of surgical plantar incision with or without perioperative fentanyl. TNF drug opioid 29135586 The fentanyl or surgical incision upregulated the expression of IL 1β, IL 6, and TNF α in the spinal cord and bilateral DRG for more than 7 days and increase of ionized calcium binding adapter molecule 1 in the spinal cord. TNF drug opioid 29135586 The combination of fentanyl and incision resulted in higher increase of IL 1β, IL 6, and TNF α in the spinal cord and bilateral DRG. TNF drug opioid 29135586 The surgical plantar incision with or without perioperative fentanyl induced significant mechanical and thermal hyperalgesia, an increased expression of IL 1β, IL 6, TNF α in the spinal cord and DRG, and activation of microglia in the spinal cord. TNF drug alcohol 29113896 Neuroinflammation produced by heavy alcohol intake is due to loops of interactions between Toll like 4 and TNF receptors, peroxisome proliferator activated receptors and the central melanocortin system: A novel hypothesis and new therapeutic avenues. TNF drug alcohol 28965650 Concomitant with a delayed increase of plasma TNF α in ethanol treated mice, plasma PTX3 was also suppressed in the early phase of sepsis. TNF drug alcohol 28965650 Although TNF α level in ethanol treated mice exceeded that in saline treated mice 16 h after CLP, PTX3 levels were still suppressed in the former group. TNF drug alcohol 28965650 Furthermore, JNK phosphorylation in ethanol treated human umbilical vein endothelial cells was suppressed even in the presence of exogenous TNF α, resulting in inhibition of PTX3 mRNA and protein expression. TNF drug alcohol 28965650 Our results suggest that ethanol suppresses de novo PTX3 synthesis via two mechanisms i.e., suppression of TNF α production and inhibition of JNK phosphorylation. TNF drug alcohol 28951767 Baicalin attenuated ethanol induced proinflammatory molecules such as TNF α, IL 1β, MIP 2, and MCP 1 and reversed redox sensitive transcription factor NF κB activation. TNF addiction intoxication 28882574 This study was designed to investigate the roles of KCs inhibitor (GdCl3) and TNF α antagonist (etanercept) on binge drinking induced liver steatosis and to explore the underlying mechanisms. TNF addiction intoxication 28882574 Taken together, KCs inhibitor and TNF α antagonist could partially attenuate binge drinking induced liver steatosis, which might be attributed to the suppression of mobilization of white adipose tissues. TNF addiction intoxication 28882574 These results suggest that KCs activation may promote binge drinking induced fatty liver by TNF α mediated activation of lipolysis in white adipose tissues. TNF drug cocaine 28813640 Cocaine self administration increased the expression of mRNA for the proinflammatory cytokine interleukin 1ß, but not tumor necrosis factor alpha, in the VTA.

TNF drug opioid 28750172 We examined the consequences of chronic morphine consumption by parents before mating on hippocampus TNF α and S100B levels in the parents and their offspring. TNF drug opioid 28750172 Hippocampus TNF α levels were significantly increased due to chronic morphine use in both male and female parents compared to those of control parents (P < 0.01). TNF drug opioid 28750172 Moreover, both male and female offspring of morphine exposed parents showed a significant increase in hippocampus TNF α levels compared to those of control offspring (P < 0.01). TNF drug nicotine 28691127 It is worthy to note that nicotine toxicity induced significant increments in serum inflammatory markers: tumor necrosis factor α and vascular cell adhesion protein 1. TNF drug alcohol 28669319 Our aim is to describe changes in serum concentration for the pro inflammatory factors TNF α, IFN γ, IL 1β, IL 8, IL 6, IL 10, IL 12 and MCP 1, for the satiety factor leptin and for factors associated with neuronal changes, neuron specific enolase (NSE) and glial activation S100 beta protein (S100 β), and explore their association with abstinence in alcohol dependent subjects after withdrawal.

TNF drug alcohol 28669319 The levels of TNF α, IL 1β, IL 8, IL 6, IL 12, MCP 1, and leptin decreased after withdrawal and remained low until M6, regardless of alcohol consumption. TNF addiction withdrawal 28669319 The levels of TNF α, IL 1β, IL 8, IL 6, IL 12, MCP 1, and leptin decreased after withdrawal and remained low until M6, regardless of alcohol consumption. TNF addiction withdrawal 28654797 Changes in brain gene expression levels of induced nitric oxide synthase (iNOS), astroglia marker, glial fibrillary acidic protein (GFAP), ionized calcium binding protein (Iba1) a microglia activation marker, a pro inflammatory mediator and tumor necrosis alpha (TNF α) were measured after withdrawal by real time polymerase chain reaction (RT PCR). TNF drug opioid 28654797 Administration of naloxone was associated with the increased expression of TNF α, GFAP, Iba1 and iNOS in the brain samples of morphine dependent mice, while the nine days treatment with both 5 and 10mg/kg simvastatin reduced such changes. TNF drug amphetamine 28621212 RAW264.7 macrophages tended to switch to the M1 phenotype, releasing more nitric oxide and proinflammatory cytokines, including tumor necrosis factor α (TNFα), interleukin (IL) 12, and IL 1β, while decreasing the release of anti inflammatory cytokine IL 10 after treatment with Meth. TNF drug amphetamine 28621212 Meth could also upregulate the protein expression of IL 1β and TNF α and downregulate the expression of Arg 1 and KLF4. TNF drug amphetamine 28552341 Meth/gp120 activated caspase 3 and increased caspase 3/7 activity in microglia and inhibition of caspase 3 by its specific inhibitor significantly decreased microglial production of TNF α and iNOS and attenuated microglia associated neurotoxic activity. TNF drug alcohol 28430931 In this study we investigated a possible association between alterations in the methylation of the BDNF IV/NGF I gene promoter and the cytokines tumor necrosis factor α (TNF α) and interleukin 6 (IL 6) in 55 male alcohol dependent patients. TNF drug alcohol 28430931 In this study we investigated a possible association between alterations in the methylation of the BDNF IV/NGF I gene promoter and the cytokines tumor necrosis factor α (TNF α) and interleukin 6 (IL 6) in 55 male alcohol dependent patients. TNF addiction withdrawal 28430931 Mean methylation of the promoter of the BDNF gene was significantly associated with the TNF α serum levels and the CIWA score during withdrawal (P < 0.001). TNF drug alcohol 28408342 These data were supported by functional evidence since chronic alcohol consumption produced no changes in the expression of TNF α or COX 2. TNF drug alcohol 28386694 Although the exercise bout increased LPS stimulated production of TNF α (%change from PRE: 5 h POST 109%; 24 h POST 49%; 48 h POST 40%) and decreased LPS stimulated production of IL 8 (5 h POST 40%; 24 h POST 50%; 48 h POST: 43%) and IL 10 (5 h POST: 37%; 24 h POST 32%; 48 h POST 31%), consuming alcohol after exercise did not affect this response. TNF drug alcohol 28350851 Expression of liver mRNA tumor necrosis factor alpha (Tnfα), C X C motif chemokine ligand 1 (Cxcl1) and circulating protein monocyte chemoattractant protein 1 (MCP 1) were also reduced in antibiotic treated alcohol fed mice. TNF drug alcohol 28319836 These manifest as increased interleukin (IL) 6 and IκBα, and suppressed IL 1β and tumor necrosis factor alpha during acute ethanol intoxication. TNF addiction intoxication 28319836 These manifest as increased interleukin (IL) 6 and IκBα, and suppressed IL 1β and tumor necrosis factor alpha during acute ethanol intoxication. TNF drug alcohol 28257601 Overexpression of miR181b 3p decreased importin α5 expression and normalized lipopolysaccharide stimulated tumor necrosis factor α expression in Kupffer cells from ethanol fed rats. TNF drug amphetamine 28237710 Rats trained to self administer METH also presented a neuroinflammatory profile characterized by microglial activation, astrogliosis and increased pro inflammatory mediators, namely tumor necrosis factor alpha, interleukine 1 beta, and matrix metalloproteinase 9. TNF drug nicotine 28197102 We found that right cervical vagotomy inhibited the cholinergic anti inflammatory pathway, aggravated myocardial lesions, up regulated the expression of TNF α, IL 1β, and IL 6, and worsened the impaired left ventricular function in murine viral myocarditis, and these changes were reversed by co treatment with nicotine by activating the cholinergic anti inflammatory pathway. TNF drug alcohol 28147432 Measures of tumor necrosis factor alpha (TNFα), interleukin 6 (IL 6), interleukin 1 receptor antagonist (IL 1ra), alcohol craving, and anxiety were assessed at baseline, immediately following imagery exposure and at discreet beer cue presentation in the ATT.

TNF drug alcohol 28095363 Also, alcohol administration augmented lipid peroxidation, mitochondrial oxidized glutathione (GSSG), interleukin 1 beta (IL 1β), tumor necrosis factor alpha (TNF α) and Bax levels in isolated hippocampal tissues. TNF drug alcohol 28087985 Hepatic toll like receptor mRNA expression and tumor necrosis factor alpha protein expression was induced by ethanol; however, the response was significantly dampened in mice co treated with tributyrin. TNF addiction withdrawal 28062186 We attempted to verify withdrawal regulation of induced nitric oxide synthase (iNOS), astroglia marker, glial fibrillary acidic protein (GFAP), ionized calcium binding protein (Iba1), a microglia activation marker, a pro inflammatory mediator, tumor necrosis alpha (TNF α) and immune receptor, toll like receptor 4 (TLR 4) genes by real time polymerase chain reaction (RT PCR). TNF drug opioid 28062186 Brain expression levels of TNF α, GFAP, Iba1 and iNOS increased in morphine withdrawn animals which were attenuated by nine days treatment with atorvastatin. TNF drug alcohol 27834881 SDS significantly inhibited protein secretion and mRNA expression of of interleukin (IL) 1β and tumor necrosis factor (TNF) α. Additionally C57BL/6 mice were orally administrated SDS for continuous 5 days, followed by three gavages of ethanol every 30 min. TNF drug alcohol 27834881 SDS significantly inhibited protein secretion and mRNA expression of of interleukin (IL) 1β and tumor necrosis factor (TNF) α. Additionally C57BL/6 mice were orally administrated SDS for continuous 5 days, followed by three gavages of ethanol every 30 min. TNF drug alcohol 27256567 Alcohol withdrawal partially restored the distribution of monocyte subsets and the frequency of IL 6 producing monocytes and increased the frequency of TNF producing cells in response to LPS and PGN stimulation to levels compared with those in HC.

TNF drug alcohol 27527870 Ethanol caused pancreatic inflammation which was indicated by the induction of TNF alpha, IL 1beta, IL 6, MCP 1 and CCR2, and the increase of CD68 positive macrophages in the pancreas. TNF drug opioid 27461080 Toll like Receptor 4 Mediates Morphine Induced Neuroinflammation and Tolerance via Soluble Tumor Necrosis Factor Signaling. TNF drug opioid 27461080 Tumor necrosis factor (TNF), a product of TLR4 signaling, promotes inflammation and facilitates glutamatergic signaling, key components of opioid tolerance. TNF drug opioid 27461080 Tumor necrosis factor (TNF), a product of TLR4 signaling, promotes inflammation and facilitates glutamatergic signaling, key components of opioid tolerance. TNF drug opioid 27461080 Therefore, we hypothesize that TLR4 mediated opioid tolerance requires TNF signaling. TNF drug opioid 27461080 By expression of a dominant negative TNF peptide via lentiviral vector injection in rat PAG to sequester soluble TNF (solTNF), we demonstrate that solTNF mediates morphine tolerance induced by TLR4 signaling, stimulates neuroinflammation (increased IL 1β and TLR4 mRNA), and disrupts glutamate reuptake (decreased GLT 1 and GLAST mRNA). TNF addiction intoxication 27455577 It was established in experiments on noninbred albino rats that the acute intoxication with methanol (1.0 LD50) decreased cellular and humoral immune responses, Th2 lymphocyte activity (to a greater extent as compared to the function of Th1 cells), reduced the blood concentration of immunoregulatory (IFN g, IL 2, IL 4) and proinflammatory (TNF, IL 1b, IL 6) cytokines on the average by 36.5% (p < 0.05), and did not affect the content of anti inflammatory cytokines (IL 10, IL 13). TNF drug alcohol 27455577 Methanol antidote 4 methylpyrazole (non competitive inhibitor of alcohol dehydrogenase) administered upon acute intoxication with methanol at a dose of 1.0 DL50 partially reduces the intoxication induced suppression of humoral and cellular immune response, activity of T helper cells, and production of IL 4 and restores blood levels of TNF, IL 1b, IFN γ, IL 4, IL 2, IL 6 to the control values.

TNF drug alcohol 27273552 We therefore hypothesized that double deletion of both IL 1RI and TNF 1 receptors (TNF 1R) may reveal the role of these pathways in regulation of alcohol intake. TNF drug alcohol 27273552 The combined deletion of TNF 1R and IL 1RI did not influence alcohol reward, but did prevent increased alcohol consumption resulting from exposure to repeated bouts of social defeat stress.

TNF addiction dependence 21886572 Recently, we have demonstrated that tumor necrosis factor α (TNF α) increases dopamine uptake and inhibits methamphetamine induced dependence. TNF drug amphetamine 21886572 Interestingly, treatment with shati AS also inhibited expression of TNF α. Transfection of the vector containing shati cDNA into PC12 cells, dramatically induced the expression of shati and TNF α mRNA, accelerated dopamine uptake, and inhibited the methamphetamine induced decrease in dopamine uptake. TNF drug amphetamine 21886572 These results suggest that the functional roles of shati in methamphetamine induced behavioral changes are mediated through the induction of TNF α expression which inhibits the methamphetamine induced increase of dopamine overflow and decrease in dopamine uptake.

TNF addiction withdrawal 11368420 At 6 hr on the following morning, TNF alpha values were near zero, but following connection of tubing and withdrawal of the initial blood sample, there was a 100 fold increase 1 hr later, followed by a decline over the next 3 hr. TNF drug alcohol 11062014 In Kupffer cells from mice treated with ethanol 1 h earlier, LPS induced TNFalpha production, and IRAK expression and activity and NFkappaB were decreased 50 60% of control. TNF drug alcohol 11062014 In contrast, in Kupffer cells from mice treated with ethanol 21 h earlier, LPS induced TNFalpha production, expression and activity of IRAK were increased 1.5 fold over controls, while NFkappaB was elevated 3 fold. TNF drug opioid 10936512 In this study, it was shown that injection of an equianalgesic dose of buprenorphine (related to morphine) into the ventral caudal PAG did not alter splenic NK cell, T cell, and macrophage functions, whereas morphine significantly (p<0.001) suppressed splenic NK cell cytotoxic activity (14 50% reduction), splenic and thymic T cell proliferation to concanavalin A (Con A, 43 76% reduction), antiTCR (T cell receptor) (85% reduction) and IL 2 (36 48% reduction), and macrophage functions including nitric oxide (36 41% reduction) and TNF alpha production (26%), and phagocytosis of Candida albicans (39%). TNF drug opioid 10921509 Morphine stimulates mesangial cell TNF alpha and nitrite production. TNF drug opioid 10921509 The effect of morphine was studied on the generation of TNF alpha with or without LPS (lipopolysaccharide) by cultured mouse mesangial cells. TNF drug alcohol 10921509 To evaluate the role of opiate receptors, we studied the effect of naloxone and naltrexone on mesangial cell TNF alpha and nitrite production. TNF drug opioid 10921509 To evaluate the role of opiate receptors, we studied the effect of naloxone and naltrexone on mesangial cell TNF alpha and nitrite production. TNF drug opioid 10921509 To determine the role of TNF alpha on mesangial cell nitrite production, we examined the effect of anti TNF alpha antibody on morphine induced nitrite production. TNF drug opioid 10921509 Morphine alone did not enhance the generation of TNF alpha by mesangial cells, however, an enhanced (P < 0.001) TNF alpha production was observed when mesangial cells were first treated with morphine for 18 h and then activated further with LPS. TNF drug opioid 10921509 Maximum release of TNF alpha was seen at a concentration of 10( 12) M of morphine. TNF drug opioid 10921509 Anti TNF alpha antibody attenuated morphine induced nitrite generation. TNF drug opioid 10921509 We conclude that morphine stimulates the generation of TNF infinity by LPS activated mesangial cells. TNF addiction sensitization 26368638 In addition, analysis of mediator expression and release over the sensitization phase has revealed that PM exposure can enhance production of Th2 cytokines such as interleukin 5 (IL 5) and the proinflammatory cytokine tumor necrosis factor alpha (TNF α).

TNF addiction intoxication 10576587 In this paper we compile and discuss the current knowledge on the pathophysiological role of TNF during intoxication with all mentioned toxins and toxicants. TNF addiction intoxication 10576587 The development of pharmaceuticals that selectively interfere with the detrimental pathways induced by TNF during intoxication with bacteria, viruses, drugs, or other chemicals requires detailed knowledge of the signaling pathways originating from the two TNF receptors (TNFR1 and TNFR2). TNF drug opioid 10469523 Morphine significantly (p <.01) inhibited TNF alpha production by LPS activated macrophages (28 +/ 8% inhibition compared with PAG injected saline rats). TNF drug alcohol 10455517 The generation of cytokine induced neutrophil chemoattractant (CINC) by hepatocytes and Kupffer cells of LPS treated rats, as well as TNF alpha secretion by Kupffer cells and alveolar macrophages of acutely ethanol intoxicated rats are also gender dependent. TNF drug alcohol 10417056 During chronic alcohol intoxication, increased levels of serum endotoxin, TNF, IL 1, and transaminase were observed and hepatic superoxide anion release was present.

TNF drug alcohol 10358198 Alcohol (ethanol) inhibits IL 8 and TNF: role of the p38 pathway. TNF drug alcohol 10358198 We examined the effects of LPS and ethanol on p38 activation and the corresponding IL 8 and TNF alpha production in human mononuclear cells. TNF addiction intoxication 10358198 Inhibition of IL 8 and TNF alpha production by acute EtOH intoxication may inhibit inflammatory focused neutrophil migration and activation and may be a mechanism explaining the increased risk of trauma and burn related infections. TNF drug alcohol 10347108 Kupffer cells were isolated 0 to 24 hours after one intragastric dose of ethanol daily, and intracellular Ca2+ ([Ca2+]i) was measured using fura 2, while tumor necrosis factor alpha (TNF alpha) was measured by enzyme linked immunosorbent assay. TNF drug alcohol 10347108 Kupffer cells were isolated 0 to 24 hours after one intragastric dose of ethanol daily, and intracellular Ca2+ ([Ca2+]i) was measured using fura 2, while tumor necrosis factor alpha (TNF alpha) was measured by enzyme linked immunosorbent assay. TNF drug alcohol 10347108 In addition, TNF alpha production by Kupffer cells was increased fourfold in cells isolated from rats treated with ethanol 24 hours earlier. TNF drug alcohol 10347108 Sterilization of the gut with antibiotics blocked all effects of ethanol on [Ca2+]i and TNF alpha release completely.

TNF addiction intoxication 9835289 In previous studies we found acute alcohol intoxication to suppress the tumor necrosis factor alpha (TNF alpha) response to in vivo challenges with bacteria or lipopolysaccharide. TNF drug alcohol 9835289 These results support the postulate that alcohol induced inhibition of TNF alpha directly contributes to the adverse effects of alcohol on PMN function by suppressing the normal autocrine amplification pathway responsible for G CSF production. TNF drug alcohol 9834283 Selective glutathione depletion of mitochondria by ethanol sensitizes hepatocytes to tumor necrosis factor. TNF drug alcohol 9834283 The purpose of this study was to determine the effect of ethanol on the sensitization of hepatocytes to TNF alpha. TNF addiction sensitization 9834283 The purpose of this study was to determine the effect of ethanol on the sensitization of hepatocytes to TNF alpha. TNF drug alcohol 9834283 Cultured hepatocytes from ethanol fed (ethanol hepatocytes) or pair fed (control hepatocytes) rats were exposed to TNF alpha, and the extent of oxidative stress, gene expression, and viability were evaluated. TNF drug alcohol 9834283 Ethanol hepatocytes, which develop a selective deficiency of mitochondrial glutathione (mGSH), showed marked susceptibility to TNF alpha. TNF drug alcohol 9834283 Nuclear factor kappaB activation by TNF alpha was significantly greater in ethanol hepatocytes than in control hepatocytes, an effect paralleled by the expression of cytokine induced neutrophil chemoattractant. TNF addiction sensitization 9834283 Similar sensitization of normal hepatocytes to TNF alpha was obtained by depleting the mitochondrial pool of GSH with 3 hydroxyl 4 pentenoate. TNF drug alcohol 9834283 Restoration of mGSH by S adenosyl L methionine or by GSH ethyl ester prevented the increased susceptibility of ethanol hepatocytes to TNF alpha. TNF drug alcohol 9834283 Its depletion caused by alcohol consumption amplifies the power of TNF alpha to generate reactive oxygen species, compromising mitochondrial and cellular functions that culminate in cell death. TNF drug alcohol 9756533 The goals of this study were to determine if suppression of neutrophil accumulation and TNF alpha production in the peritoneal cavity occurs in mice exposed to a chemical stressor [ethanol (EtOH)], to evaluate the role of EtOH induced increases in endogenous glucocorticoids in any such suppression, and to determine if decreased tumor necrosis factor alpha (TNF alpha) production is responsible for decreases in neutrophil accumulation in EtOH treated mice.

TNF drug alcohol 9679050 Two hours after ethanol administration, the LPS induced increase in [Ca2+]i and TNF alpha release by Kupffer cells was diminished by 50%, and these parameters were reciprocally enhanced twofold at 24 hours. TNF drug alcohol 9679050 Sterilization of the gut with antibiotics blocked all effects of ethanol on [Ca2+]i and TNF alpha release completely. TNF drug amphetamine 9657097 F4614 is known to lack hypotensive effects of human TNF alpha without losing its anti tumor effect in mice transplanted with Meth A sarcoma. TNF drug alcohol 9497367 Accordingly, pretreatment with MG132 reduced JNK dependent apoptosis caused by heat shock or ethanol, but it was unable to block JNK independent apoptosis induced by TNFalpha. TNF drug alcohol 9514301 One potential mechanism of ethanol induced immunosuppression is through its ability to suppress alveolar macrophage production of tumor necrosis factor (TNF alpha). TNF drug alcohol 9514301 One potential mechanism of ethanol induced immunosuppression is through its ability to suppress alveolar macrophage production of tumor necrosis factor (TNF alpha).

TNF drug alcohol 9347083 Alterations in tumor necrosis factor alpha, interferon gamma, and interleukin 6 production by natural killer cell enriched peripheral blood mononuclear cells in chronic alcoholism: relationship with liver disease and ethanol intake. TNF drug alcohol 9347083 Accordingly, an increased concentration of this cytokine was detected in the supernatants of cirrhotic patients and active EtOH intake, particularly after IFN alpha stimulation (p < 0.05); whereas, in patients with at least 1 year of alcohol withdrawal, TNF alpha levels remained within normal range. TNF addiction withdrawal 9347083 Accordingly, an increased concentration of this cytokine was detected in the supernatants of cirrhotic patients and active EtOH intake, particularly after IFN alpha stimulation (p < 0.05); whereas, in patients with at least 1 year of alcohol withdrawal, TNF alpha levels remained within normal range. TNF drug alcohol 9347081 In this study, we assessed the effect of alcohol ingestion on the expression of tumor necrosis factor alpha (TNF alpha), and the chemokines macrophage inflammatory protein 2 (MIP 2) and macrophage inflammatory protein 1 alpha (MIP 1 alpha) from murine alveolar macrophages (AMs) cultured ex vivo. TNF drug alcohol 9347081 In this study, we assessed the effect of alcohol ingestion on the expression of tumor necrosis factor alpha (TNF alpha), and the chemokines macrophage inflammatory protein 2 (MIP 2) and macrophage inflammatory protein 1 alpha (MIP 1 alpha) from murine alveolar macrophages (AMs) cultured ex vivo. TNF drug alcohol 9347081 Two week ethanol feeding resulted in substantial impairment in the lipopolysaccharide (LPS) induced expression of TNF alpha, MIP 2, and MIP 1 alpha mRNA, and protein from LPS stimulated AMs, compared with cytokine production from AMs obtained from CD 1 mice receiving an isocaloric control diet. TNF drug alcohol 8947315 This study tests two hypotheses: (1) prior exposure to LPS induces cross tolerance for the hepatic effects of subsequent short term alcohol intoxication; and (2) short term alcohol intoxication renders the liver resistant to the effects of acute endotoxemia, resulting in reduced production of superoxide and tumor necrosis factor. TNF addiction intoxication 8947315 This study tests two hypotheses: (1) prior exposure to LPS induces cross tolerance for the hepatic effects of subsequent short term alcohol intoxication; and (2) short term alcohol intoxication renders the liver resistant to the effects of acute endotoxemia, resulting in reduced production of superoxide and tumor necrosis factor. TNF drug alcohol 8947315 Acute ethanol intoxication for 5 hr significantly reduced LPS induced serum tumor necrosis factor activity and free radical release by the perfused liver. TNF addiction intoxication 8947315 Acute ethanol intoxication for 5 hr significantly reduced LPS induced serum tumor necrosis factor activity and free radical release by the perfused liver. TNF drug alcohol 8730220 Interleukin 6 tumor necrosis factor alpha clearance and metabolism in vivo and by the isolated, perfused liver in the rat: effect of acute alcohol administration. TNF drug alcohol 8730220 Plasma clearance and organ distribution of intravenously injected human recombinant [125I]interleukin (IL) 6 and [125I]tumor necrosis factor (TNF) alpha were studied in male rats, 2 hr after intravenous alcohol (ethanol) administration (single dose, 2.2 g.kg 1 body weight). TNF drug alcohol 8730220 Plasma clearance and organ distribution of intravenously injected human recombinant [125I]interleukin (IL) 6 and [125I]tumor necrosis factor (TNF) alpha were studied in male rats, 2 hr after intravenous alcohol (ethanol) administration (single dose, 2.2 g.kg 1 body weight). TNF drug alcohol 8730220 Acute ethanol administration significantly increased plasma clearance rate for both cytokines (36% and 72%, for IL 6 and TNF alpha, respectively), decreased the t1/2 alpha (30% and 11%, for IL 6 and TNF alpha, respectively), abolished the slow (beta) phase component for TNF alpha, and increased t1/2 beta for IL 6 (31%). TNF drug alcohol 8730220 Although alcohol did not affect organ distribution of TNF alpha, it increased the IL 6 content in the liver, kidney, and blood. TNF drug alcohol 8730220 Ethanol addition to the perfusate (35 mM, final concentration) significantly increased TNF alpha uptake (24%), without affecting IL 6 uptake or the degradation rate of either cytokine. TNF drug alcohol 8730220 Data presented in this study demonstrate that: (1) acute alcohol consumption can alter the kinetic behavior of IL 6 and TNF alpha in the bloodstream, mainly by accelerating their clearance which, in turn, may counteract the outcome of cytokine secretion and delivery to the blood; and (2) short exposure of liver to ethanol levels commonly seen in humans after binge drinking may alter its capacity to take up cytokines.

TNF drug alcohol 1662988 Ethanol affects release of TNF and GM CSF and membrane expression of TNF receptors by human macrophages. TNF drug alcohol 1662988 More recently, ethanol was shown to impair the capacity of pulmonary macrophages to produce superoxide anion and tumor necrosis factor (TNF). TNF drug alcohol 1662988 More recently, ethanol was shown to impair the capacity of pulmonary macrophages to produce superoxide anion and tumor necrosis factor (TNF). TNF drug alcohol 1662988 Furthermore, exposure to ethanol compromises macrophage's ability to respond to stimulation with TNF and granulocyte macrophage colony stimulating factor (GM CSF), and kill an intracellular pathogen, Mycobacterium avium. TNF drug alcohol 1662988 Based on these previous findings, we examined whether exposure to ethanol affects superoxide anion production, synthesis of cytokines, and expression of membrane receptors to TNF on human monocyte derived macrophages. TNF drug alcohol 1662988 When macrophages were then treated with lipopolysaccharide (LPS) in the presence of ethanol, high concentrations of TNF and GM CSF were produced, but subsequent stimulation with LPS (second stimulus) was associated with significant impairment on synthesis and release of both TNF and GM CSF. TNF drug alcohol 1662988 In addition, although ethanol had no effect on TNF binding to resting macrophages and to macrophages infected with M. avium, ethanol significantly reduced the expression of TNF receptors on interferon gamma stimulated macrophages. TNF drug alcohol 2668425 The effects of acute and chronic alcoholism on tumor necrosis factor and the inflammatory response. TNF drug alcohol 2668425 Because the macrophage secretory protein, tumor necrosis factor (TNF), plays a central role in the inflammatory cascade, the effect of acute and chronic alcoholism on lipopolysaccharide (LPS) induced TNF activity was studied. TNF drug alcohol 2668425 Because the macrophage secretory protein, tumor necrosis factor (TNF), plays a central role in the inflammatory cascade, the effect of acute and chronic alcoholism on lipopolysaccharide (LPS) induced TNF activity was studied. TNF drug alcohol 2668425 Intravenous LPS caused a substantial increase in serum TNF at 90 min in both normal and chronic alcoholic rats. TNF drug alcohol 2668425 In marked contrast, peak serum TNF levels were significantly suppressed in normal and chronic alcoholic rats given an acute injection of ethanol. TNF drug alcohol 2668425 Similar levels of TNF were found in chronic alcoholic rats after intratracheal LPS. TNF drug alcohol 2668425 However, acute ethanol intoxication significantly inhibited LPS induced TNF in bronchoalveolar lavage fluid. TNF addiction intoxication 2668425 However, acute ethanol intoxication significantly inhibited LPS induced TNF in bronchoalveolar lavage fluid. TNF drug alcohol 2668425 Alcohol induced inhibition of TNF is a potential mechanism of the antiinflammatory effects of ethanol. TNF addiction dependence 2783463 Sequence dependence of administration of human recombinant tumor necrosis factor and interleukin 2 in murine tumor therapy. TNF drug alcohol 2648095 Alcohol suppresses lipopolysaccharide induced tumor necrosis factor activity in serum and lung. TNF drug alcohol 2648095 Acute ethanol intoxication markedly suppressed both serum and lung tumor necrosis factor elicited in response to lipopolysaccharide. TNF addiction intoxication 2648095 Acute ethanol intoxication markedly suppressed both serum and lung tumor necrosis factor elicited in response to lipopolysaccharide. TNF drug alcohol 2648095 Thus, the anti inflammatory effects of ethanol may be secondary to suppression of macrophage derived tumor necrosis factor.

HTR1A drug cocaine 29217539 Although this effect is partially inhibited by a 5 HT2C receptor antagonist (SB242084), lorcaserin also has effects at 5 HT2A and 5 HT1A receptors, and the relative contribution of these receptors to its anti cocaine effects has not been investigated. HTR1A drug cocaine 29217539 Antagonism of 5 HT2C (but not 5 HT1A or 5 HT2A) receptors blocked the effects of lorcaserin on cocaine and MDPV self administration. HTR1A drug psychedelics 28890736 This 25B NBOMe induced rhabdomyolysis was inhibited by the 5 HT2A receptor antagonists ritanserin and aripirazole, but not by the 5 HT1A + 5 HT1B receptor antagonist propranolol and the 5 HT3 receptor antagonist granisetron, indicating 5 HT2A dependent rhabdomyolysis. HTR1A drug cannabinoid 28268256 Studies show that cannabidiol, the main non psychotomimetic phytocannabinoid found in Cannabis sativa, reduces anxiety via 5 HT1A and (indirect) cannabinoid receptor activation in paradigms assessing innate responses to threat. HTR1A addiction reward 27866999 The 5 HT1A/1B receptor agonist eltoprazine increases both catecholamine release in the prefrontal cortex and dopamine release in the nucleus accumbens and decreases motivation for reward and "waiting" impulsivity, but increases "stopping" impulsivity. HTR1A addiction relapse 27515792 We observed decreased drug seeking behavior on ED1 following 10 mg/kg S propranolol (β adrenergic and 5 HT1A/1B receptor antagonist), R propranolol (5 HT1A/1B receptor antagonist), or racemic propranolol in both male and female rats. HTR1A addiction relapse 27515792 Based on these results, we investigated the effects of blocking 5 HT and β adrenoceptor transmission in DH on drug seeking during ED1 by infusing a cocktail of WAY100635 plus GR127935 (5 HT1A/1B receptor antagonists), betaxolol plus ICI 118 551 (β1 and β2 antagonists), or S propranolol alone.

HTR1A drug alcohol 27375424 In slices from naïve animals, application of a 5 HT1A receptor antagonist blocked the effect of 5 HT on the fEPSPs recorded in presence of picrotoxin, suggesting that third trimester ethanol exposure acts by inhibiting the function of these receptors. HTR1A drug cannabinoid 27289270 Cannabidiol, a therapeutic with potential serotonin (5 hydroxytryptamine; 5 HT) 5 HT1A receptor agonist activity, is the second most prevalent cannabinoid in Cannabis after Δ(9) THC.

HTR1A drug cannabinoid 27289270 In addition to showing that cannabidiol and a 5 HT1A receptor agonist have overlapping behavioral effects, the current results suggest that 5 HT1A agonism enhances the CB1 receptor mediated effects of Δ(9) THC. HTR1A drug alcohol 27273539 Additionally, this effect was blocked by the 5 HT1A/1B receptor antagonist methiothepin, suggesting that altered serotonergic activity in the BLA may contribute to the efficacy of pindolol to reduce ethanol intake following long term exposure.

HTR1A drug nicotine 11412838 Effects of 5 HT1A and 5 HT2 receptor agonists on the behavioral and neurochemical consequences of repeated nicotine treatment. HTR1A drug nicotine 11412838 This study investigated the effects of repeated daily (15 days) treatment with nicotine, alone or in combination with the 5 HT1A/7 receptor agonist (+/ ) 8 hydroxy 2 (di n propylamino)tetralin (8 OH DPAT) or the 5 HT2 receptor agonist (+/ ) 2,5 dimethoxy 4 iodoamphetamine (DOI) on locomotor sensitization, mesolimbic dopamine neurochemistry and on behavioral inhibition in the rat.

HTR1A drug nicotine 11374339 The social interaction test of anxiety was used to investigate the effects of a range of doses of ( ) nicotine (2.5 4000 ng) following DRN infusion, and whether co administration of the specific 5 HT1A receptor antagonist WAY 100635 could antagonise the anxiolytic action of nicotine. HTR1A drug nicotine 11374339 The present findings therefore suggest that the DRN plays an important role in mediating the acute effects of nicotine on anxiety, as measured in the social interaction test, and that the anxiolytic effect is mediated by activation of somatodendritic 5 HT1A autoreceptors. HTR1A drug alcohol 11198050 Results showed that the 5 HT releaser d fenfluramine, the selective serotonin reuptake inhibitor fluoxetine, the 5 HT1A receptor agonist 8 hydroxy 2[di n propylamino]tetralin, the partial 5 HT1A receptor agonist buspirone, and the 5 HT1B/5 HT2C receptor agonist 1 (3 trifluoromethylphenyl)piperazine, but not the 5 HT2A/5 HT2C receptor agonist 1 (2,5 dimethoxy 4 iodophenylaminopropane) 2, selectively reduced responding on a lever leading to presentation of an ethanol paired conditioned stimulus.

HTR1A drug psychedelics 11022403 (+/ )Pindolol attenuated the suppressant effect of the 5 HT autoreceptor agonist lysergic acid diethylamide (LSD) on the firing activity of 5 HT neurons, suggesting that (+/ )pindolol antagonized somatodendritic 5 HT1A autoreceptors in the dorsal raphe nucleus. HTR1A drug psychedelics 11022403 However, following a 2 day washout period, the suppressant effect of LSD was still attenuated, indicating rather a desensitization of 5 HT1A autoreceptors had occurred. HTR1A addiction relapse 11022403 Although pindolol is capable of antagonizing the 5 HT1A autoreceptor upon the initiation of a 5 HT reuptake blocker treatment, it also induces a desensitization of this 5 HT1A autoreceptor, which could explain why patients do not relapse upon its discontinuation when they continue taking a 5 HT reuptake blocker.

HTR1A drug alcohol 10924015 By means of in vitro quantitative autoradiography, we used [3H]citalopram, [3H]8 OH DPAT, and [3H]GR65630 to label 5 HTT, 5 HT1A receptors, and 5 HT3 receptors in the brain of alcohol naïve FH rats, Wistar Kyoto (WKY) rats, and FH rats given free access to 5% ethanol and/or after 24 to 48 hr withdrawal. HTR1A addiction withdrawal 10924015 By means of in vitro quantitative autoradiography, we used [3H]citalopram, [3H]8 OH DPAT, and [3H]GR65630 to label 5 HTT, 5 HT1A receptors, and 5 HT3 receptors in the brain of alcohol naïve FH rats, Wistar Kyoto (WKY) rats, and FH rats given free access to 5% ethanol and/or after 24 to 48 hr withdrawal. HTR1A drug alcohol 10924015 In alcohol naïve rats, FH rats displayed significantly higher (p < 0.05) densities of [3H]citalopram binding in the nucleus accumbens (+30%), lateral septum (+37%), ventral pallidum (+21%), and ventral tegmental area (+24%), as well as an increased binding of [3H]8 OH DPAT to 5 HT1A receptors in the frontal and parietal cortex (+33%), occipital and temporal cortex (+25%), and hippocampal CA3 region (+31%), compared with WKY rats, whereas both strains exhibited comparable [3H]GR65630 binding to 5 HT3 receptors. HTR1A drug alcohol 10924015 The elevated 5 HT transporters and 5 HT1A receptors in the mesocorticolimbic areas in FH rats may reflect a potential innate altered transmission at serotonergic synapses, which possibly may affect the high intake of alcohol in FH rats. HTR1A drug alcohol 10924015 The region specific alterations of 5 HT1A receptors in FH rat brain after ethanol challenges suggest that 5 HT1A receptors are sensitive to ethanol challenges, whereas 5 HTT are apparently insensitive. HTR1A drug amphetamine 10780831 The suppressant actions of RU 24969 on amphetamine self administration and CR responding involve stimulation of 5 HT1B receptors, since they were reversed by the 5 HT1B/1D antagonist GR 127935 (3 mg/kg), but not by the 5 HT1A antagonist WAY 100635 (1 mg/kg).

HTR1A addiction aversion 10475723 The 5 HT1A receptor agonist flesinoxan increases aversion in a model of panic like anxiety in rats. HTR1A addiction aversion 10475723 Data suggest that selective activation of 5 HT1A receptors (pre and/or post synaptic in brain and/or periphery) following systemic administration of 5 HT1A receptor full agonists exacerbates aversion in animals or patients with panic anxiety; activation of these receptor subtypes may probably mediate the panicogenic action reported under certain circumstances with non selective 5 HT mimetics.

HTR1A drug alcohol 9394117 These complex findings suggest that biochemical properties other than 5 HT2A receptor antagonism (e.g., 5 HT1A receptor agonism) may be involved in the effects of amperozide and FG 5974 on alcohol intake and other consummatory behaviors.

HTR1A drug benzodiazepine 9128832 In vitro binding and quantitative autoradiographic experiments with [3H]8 hydroxy 2 (di n propylamino)tetralin ([3H]8 OH DPAT) showed that the characteristics of 5 HT1A receptor binding sites in the hippocampus and the dorsal raphe nucleus were not significantly altered by the administration of diazepam under the treatment protocols A, B and C.

HTR1A drug benzodiazepine 8905669 Behavioral effects of acute diazepam administration were compared with those of the 5 HT1A anxiolytic buspirone and those of ethanol in C57BL/6J mice. HTR1A addiction reward 8728552 Whatever the experimental parameters and stage of the learning, an acute administration of drugs able to reduce 5 HT neuronal activity (benzodiazepines; 5 HT1A receptor partial agonists: buspirone and MDL 73005EF) or enhance 5 HT transmission (5 HT reuptake inhibitors: indalpine and zimelidine; 5 HT1A receptor full agonist: 8 OH DPAT) failed significantly to alter choice strategy (decreased or increased preference for the large but delayed reward, respectively), as they did in other situations such as a T maze procedure. HTR1A drug alcohol 8801594 The present series of experiments was conducted to investigate whether the previously reported ethanol intake reducing effects of the 5 HT1A receptor agonist ipsapirone could be based on possible stimulus similarities between both compounds. HTR1A drug benzodiazepine 8786542 These data indicate that learning is sensitive to disruption by drugs with 5 HT1A agonist properties, and that atypical anxiolytics with 5 HT1A agonist properties are no less disruptive to "cognitive" processes than typical anxiolytics such as the benzodiazepine alprazolam. HTR1A addiction reward 8587903 Drugs with different intrinsic activity at 5 HT1A receptors and antagonists at 5 HT2A/2C and 5 HT3 receptors were studied for their ability to increase the rates of punished operant responding in rats. HTR1A drug benzodiazepine 8587903 Like chlordiazepoxide (5 and 10 mg/kg) and diazepam (1.25 and 2.5 mg/kg), 0.125 mg/kg 8 hydroxy 2 (di n propylamino)tetralin (8 OH DPAT), a 5 HT1A receptor agonist, and 5 and 10 mg/kg ipsapirone, a partial agonist at these receptors, increased the rates of punished responding, whereas (S) WAY 100135, a 5 HT1A receptor antagonist, had no effect at doses from 1 to 10 mg/kg. HTR1A addiction reward 8587903 The results show that agents acting as full or partial agonists at 5 HT1A receptors and blockers of postsynaptic 5 HT2C receptors have anxiolytic like effects in a model of punished operant responding, whereas antagonists at 5 HT1A and 5 HT3 receptors have no such effect. HTR1A drug benzodiazepine 8666006 The effect of ipsapirone, a partial agonist at 5 HT1A receptors, and of diazepam on punished operant responding was studied in rats injected intracerebroventricularly with 150 microg 5,7 dihydroxytryptamine to deplete brain serotonin or pretreated with (S) WAY 100135 (N tert butyl) 3 4 (2 methoxyphenyl)piperazin 1 yl 2 phenylpropanamide dihydrochloride), an antagonist at 5 HT1A receptors. HTR1A addiction reward 8666006 The effect of ipsapirone, a partial agonist at 5 HT1A receptors, and of diazepam on punished operant responding was studied in rats injected intracerebroventricularly with 150 microg 5,7 dihydroxytryptamine to deplete brain serotonin or pretreated with (S) WAY 100135 (N tert butyl) 3 4 (2 methoxyphenyl)piperazin 1 yl 2 phenylpropanamide dihydrochloride), an antagonist at 5 HT1A receptors. HTR1A addiction addiction 8666006 The results suggest that ipsapirone releases behaviour that is suppressed by punishment by stimulating presynaptic 5 HT1A receptors. HTR1A drug benzodiazepine 8539344 The benzodiazepine receptor agonists chlordiazepoxide, diazepam and alprazolam, the 5 HT1A receptor agonists flesinoxan and ipsapirone and the 5 HT uptake inhibitor clomipramine selectively (no effect on crossings) reduced SAP. HTR1A drug benzodiazepine 8539344 In conclusion, SAP and intention movements were reduced selectively by anxiolytic agents from different classes, including benzodiazepine receptor agonists, 5 HT1A receptor agonists and a 5 HT uptake inhibitor, whereas an alpha 2 adrenoceptor agonist and a MAO inhibitor reduced SAP non selectively. HTR1A drug benzodiazepine 8539340 Drugs with anxiolytic effects that act on the benzodiazepine GABAA receptor complex and on 5 HT1A receptors systematically and potently alter specific vocalizations in rodents and primates in a pharmacologically reversible manner; the specificity of these effects on vocalizations is evident due to the effectiveness of low doses that do not compromise other physiological and behavioral processes. HTR1A addiction withdrawal 8521905 The expression of central 5 HT1A and 5 HT1B receptors was studied in several brain areas of rats subjected to a 2 week period of chronic alcoholization, followed by 18 h withdrawal. HTR1A drug alcohol 8521905 Quantitative autoradiography indicated that the ethanol treatment provoked an increase (approximately +30%) in the labeling by [3H]8 hydroxy 2 (di n propylamino)tetralin ([3H]8 OH DPAT) and [3H]N [2 [4 (2 methoxyphenyl) 1 piperazinyl]ethyl] N (2 pyridinyl) cyclohexane carboxamide ([3H]WAY 100635) of 5 HT1A autoreceptors in the dorsal raphe nucleus, accompanied by a concomitant decrease in the labeling of postsynaptic 5 HT1A receptors in the hippocampus (approximately 20%), anterior (approximately 30%) and posterior (approximately 32%) cortices. HTR1A drug alcohol 8521905 These data suggest that altered sensitivity of chronically alcoholized rats to 5 HT1A and 5 HT1B receptor ligands may result from alcohol induced changes in the transcription of the genes encoding these receptors. HTR1A drug alcohol 8521904 Modification of behavioral effects of 8 hydroxy 2 (di n propylamino)tetralin following chronic ethanol consumption in the rat: evidence for the involvement of 5 HT1A receptors in ethanol dependence. HTR1A addiction dependence 8521904 Modification of behavioral effects of 8 hydroxy 2 (di n propylamino)tetralin following chronic ethanol consumption in the rat: evidence for the involvement of 5 HT1A receptors in ethanol dependence. HTR1A drug alcohol 8521904 Taken together, these results indicate that chronic ethanol exposure differentially alters sensitivity to several pharmacological effects of the 5 HT1A receptor ligand 8 OH DPAT. HTR1A drug alcohol 8521904 They further support the involvement of 5 HT (5 hydroxytryptamine, serotonin) systems in alcohol abuse and therapeutic interventions using 5 HT1A ligands. HTR1A drug psychedelics 8539318 Simultaneous administration of alpha 2 adrenergic agents with LSD shifted the dose response curve to the left only when the adrenergic agent also possessed at least moderate affinity for the 5 HT1A receptor. HTR1A drug psychedelics 8539318 While previous studies have suggested that the nature of the LSD cue may be essentially expressed by 5 HT2 receptor activation, the present data show that this cue can be modulated by effects of LSD at 5 HT1A and at other monoamine neurotransmitter receptors. HTR1A drug cocaine 7566671 Repeated cocaine administration reduces 5 HT1A mediated prolactin secretion in rats. HTR1A drug cocaine 7566671 The prolactin and behavioral responses elicited by the 5 HT1A agonist 8 OH DPAT (8 hydroxy 2 [di n propylamino]tetralin) were examined in male rats previously exposed to chronic cocaine (15 mg/kg, i.p., b.i.d., 7 days) or saline. HTR1A drug cocaine 7566671 Our data agree with the findings of others and suggest that 5 HT1A receptors mediating neuroendocrine secretion become subsensitive after repeated cocaine administration. HTR1A drug amphetamine 7796132 A significant increase of [3H]SCH 23390 binding to D1 DA receptors was observed in the substantia nigra pars reticulata 1 day but not 15 days after the cessation of AMPH treatment, whereas [3H]8 OH DPAT binding to 5 HT1A sites was found to be significantly enhanced in the dorsal raphe nucleus at both time points. HTR1A addiction aversion 7796851 Pindolol and ( ) propranolol, non selective antagonists of beta adrenoceptors and 5 HT1 receptors, 1 (2 methoxyphenyl) 4 [4 (2 phethalimido) butyl] piperazine hydrobromide (NAN 190), a 5 HT1A receptor antagonist, 3 tropanyl 3,5 dichlorobenzoate (MDL72222) and metoclopramide, 5 HT3 receptor antagonists, significantly inhibited the calcitonin induced anti aversive effects. HTR1A drug opioid 7796851 These results suggest that beta adrenoceptor, 5 HT1A, 5 HT3, GABAA and GABAB receptors, but not alpha adrenoceptor, opioid nor 5 HT2A receptors, are involved in the inhibitory effect of calcitonin on intrathecally injected N methyl D aspartate induced aversive behavior in mice. HTR1A addiction aversion 7796851 These results suggest that beta adrenoceptor, 5 HT1A, 5 HT3, GABAA and GABAB receptors, but not alpha adrenoceptor, opioid nor 5 HT2A receptors, are involved in the inhibitory effect of calcitonin on intrathecally injected N methyl D aspartate induced aversive behavior in mice. HTR1A drug cocaine 8594482 These studies demonstrate that prenatal cocaine produces differential changes in neuroendocrine responses following challenge with a 5 HT releaser versus a 5 HT1A agonist and suggest differential functional alterations in both pre and postsynaptic components of 5 HT pathways. HTR1A drug cocaine 8594482 Gender differences in prenatal cocaine effects on postsynaptic receptor function were more clearly shown in study II, which demonstrated that at the same postnatal age, 5 HT1A mediated neuroendocrine responses were significantly potentiated in male but not female cocaine exposed progeny. HTR1A drug benzodiazepine 7753959 VA21B7 was compared with standard 5 HT3 receptor antagonists such as ondansetron, tropisetron and granisetron, with the 5 HT1A agent buspirone and with diazepam. HTR1A drug benzodiazepine 7724700 The triazolobenzodiazepine alprazolam, the 5 HT uptake inhibitors fluvoxamine and clomipramine, the mixed 5 HT/NA uptake inhibitor imipramine, the full 5 HT1A receptor agonists 8 OH DPAT and flesinoxan, the partial 5 HT1A receptor agonists buspirone, ipsapirone and BMY 7378, the alpha 2 adrenoceptor agonist clonidine and the alpha 2 adrenoceptor antagonist yohimbine reduced conditioned USV. HTR1A drug alcohol 7945982 On the other hand, treatment of intact rats with the 5 HT1A receptor agonist ipsapirone (2.5 mg/kg), a drug that also decreases ethanol drinking in two bottle intake tests, did increase the duration of aversive groomings, whereas measures of ingestion remained unaffected. HTR1A addiction aversion 7945982 On the other hand, treatment of intact rats with the 5 HT1A receptor agonist ipsapirone (2.5 mg/kg), a drug that also decreases ethanol drinking in two bottle intake tests, did increase the duration of aversive groomings, whereas measures of ingestion remained unaffected. HTR1A drug cocaine 7956751 These results suggest selective alteration of presynaptic 5 HT1A or postsynaptic 5 HT2A/2C function in cocaine addicts. HTR1A drug alcohol 7919948 This SIH can be antagonized by benzodiazepines, alcohol and 5 HT1A receptor agonists, but not by specific 5 HT reuptake inhibitors (SSRIs) or 5 HT3 receptor antagonists. HTR1A drug cocaine 7813744 Additionally, repeated cocaine exposure produces subsensitive 5 HT1A mediated hormone responses, and supersensitive 5 HT2 mediated responses. HTR1A addiction withdrawal 7913228 Effects of 5 HT1A receptor ligands on a safety signal withdrawal procedure of conflict in the rat. HTR1A addiction addiction 7913228 The present study evaluated in the rat the ability of various 5 HT1A receptor agonists to exert an "anxiolytic like" release of the suppression of lever pressing for food induced by the withdrawal of a conditioned signal for safety without presentation of a conditioned signal for punishment. HTR1A addiction withdrawal 7913228 The present study evaluated in the rat the ability of various 5 HT1A receptor agonists to exert an "anxiolytic like" release of the suppression of lever pressing for food induced by the withdrawal of a conditioned signal for safety without presentation of a conditioned signal for punishment. HTR1A addiction reward 8050464 Using a two lever operant drug discrimination procedure, rats were trained to discriminate the 5 HT1A receptor agonist, flesinoxan (0.5 mg/kg i.p. HTR1A drug benzodiazepine 8057528 Effects of SUN 8399, a potent and selective 5 HT1A agonist, on conflict behavior and ambulatory activity in mice: comparison with those of buspirone, tandospirone and diazepam. HTR1A drug benzodiazepine 8057528 administration of SUN 8399, a selective 5 HT1A agonist, on the operant behavior under a MULT VI 1.5 min/FR 5 punishment schedule of food reinforcement and on the ambulatory activity were evaluated in mice, and the characteristics were compared with those of other 5 HT1A agonists, buspirone and tandospirone, and the benzodiazepine diazepam. HTR1A addiction addiction 8057528 administration of SUN 8399, a selective 5 HT1A agonist, on the operant behavior under a MULT VI 1.5 min/FR 5 punishment schedule of food reinforcement and on the ambulatory activity were evaluated in mice, and the characteristics were compared with those of other 5 HT1A agonists, buspirone and tandospirone, and the benzodiazepine diazepam. HTR1A addiction reward 8057528 administration of SUN 8399, a selective 5 HT1A agonist, on the operant behavior under a MULT VI 1.5 min/FR 5 punishment schedule of food reinforcement and on the ambulatory activity were evaluated in mice, and the characteristics were compared with those of other 5 HT1A agonists, buspirone and tandospirone, and the benzodiazepine diazepam. HTR1A drug amphetamine 8057528 However, SUN 8399 possesses different behavioral characteristics from those of the other two 5 HT1A agonists in terms of interactions with methamphetamine and scopolamine. HTR1A drug alcohol 8204202 5 HT1A receptor agonists reduce ethanol induced locomotor activity in mice. HTR1A drug alcohol 8204202 Previous studies have suggested that 5 HT1A receptor agonists may reduce ethanol preference in rats. HTR1A drug alcohol 8204202 In the present study on mice, the 5 HT1A receptor agonists (8 OH DPAT), ipsapirone, and buspirone all antagonized the locomotor activity (LMA) stimulatory effect of ethanol (2.5 g/kg). HTR1A drug alcohol 8204202 The present results provide further support for the notion that the LMA increasing effect of ethanol may be homologous to its reinforcing properties and that 5 HT1A receptor agonists may counteract these properties as well.

HTR1A addiction reward 7846206 In general, the arylpiperazine, 5 HT1A compounds increased reinforcement rate, decreased response rate and disrupted the profile of the IRT distribution. HTR1A drug benzodiazepine 7846206 The effects of the four arylpiperazine 5 HT1A compounds on the IRT distribution profile were different from the AD profile of 5 HTP and the benzodiazepine anxiolytic profile of diazepam. HTR1A drug benzodiazepine 7846191 Three experiments evaluated the association between USV and "distress" by comparing the effects of diazepam as a prototypic benzodiazepine agonist and the putative anxiolytic gepirone with affinity for 5 hydroxytryptamine (5 HT1A) receptors in naive and diazepam withdrawn subjects. HTR1A addiction dependence 22298627 Assessment of the dependence potential of the potent high efficacy 5 HT1A agonist S 14506 in rats. HTR1A drug alcohol 8032152 For example, buspirone, a 5 HT1A receptor partial agonist, reduced anxiety and alcohol craving, but not AC; a 5 HT partial agonist, m CPP, increased craving in abstinent alcoholics; modest reductions in AC were observed with a 5 HT3 antagonist, ondansetron (0.5 mg/day, but not 4 mg/day). HTR1A addiction relapse 8032152 For example, buspirone, a 5 HT1A receptor partial agonist, reduced anxiety and alcohol craving, but not AC; a 5 HT partial agonist, m CPP, increased craving in abstinent alcoholics; modest reductions in AC were observed with a 5 HT3 antagonist, ondansetron (0.5 mg/day, but not 4 mg/day).

HTR1A drug benzodiazepine 8201242 Using measurements of rodent behaviour in the mouse light and dark test box and rat social interaction, anxiolytic agents such as diazepam and putative anxiolytic agents such as the 5 HT1A and 5 HT3 receptor ligands 8 OH DPAT and low doses of tropisetron release behaviour suppressed by the aversive situation.

HTR1A drug benzodiazepine 7902543 Co administration of buspirone (5 HT1A agonist) or ondansetron (5 HT3 antagonist), but not mianserin (5 HT1C antagonist) or ketanserin (5 HT2 antagonist) with diazepam potentiated the hypersensitivity to FG 7142 following chronic treatment with diazepam. HTR1A drug benzodiazepine 7902543 These results suggest that co administration of buspirone or ondansetron with diazepam may potentiate the development of physical dependence on diazepam; 5 HT1A and 5 HT3 receptors may be partially involved in the development of physical dependence on diazepam.

HTR1A drug cocaine 8405113 Repeated cocaine administration does not affect 5 HT receptor subtypes (5 HT1A, 5 HT2) in several rat brain regions. HTR1A drug cocaine 8405113 In order to examine whether cocaine induced behavioral sensitization is modulated by changes in serotonin receptor subtypes, we measured the binding of [3H]8 hydroxy 2 (di n propylamino)tetralin ([3H]8 OH DPAT) to 5 HT1A receptors and of [3H] ketanserin to 5 HT2 receptors in various brain regions of cocaine treated and saline treated (control) rats. HTR1A addiction sensitization 8405113 In order to examine whether cocaine induced behavioral sensitization is modulated by changes in serotonin receptor subtypes, we measured the binding of [3H]8 hydroxy 2 (di n propylamino)tetralin ([3H]8 OH DPAT) to 5 HT1A receptors and of [3H] ketanserin to 5 HT2 receptors in various brain regions of cocaine treated and saline treated (control) rats. HTR1A drug cocaine 8405113 These results suggest that the enhanced functional sensitivity of 5 HT1A or 5 HT2 receptor subtypes seen with cocaine may be associated with alterations in processes distal to receptors rather than changes in the number or the affinity of the receptors. HTR1A drug cocaine 8332619 The results of Experiment 1 indicated that rats receiving cocaine via osmotic minipumps exhibited marked 5 HT1A receptor subsensitivity. HTR1A drug cocaine 8332619 In contrast, rats receiving daily cocaine injections sometimes demonstrated evidence of 5 HT1A supersensitivity and sometimes demonstrated evidence of 5 HT1A normosensitivity. HTR1A drug cocaine 8332619 Overall, the results indicate that, at least in the present behavioral paradigm, the effects of chronic cocaine administration are mediated by changes in 5 HT1A receptor sensitivity but not by changes in 5 HT1B receptor sensitivity.

HTR1A drug benzodiazepine 7689737 The modulation of 5HT binding sites and 5HT1A receptors by the administration of clonazepam for various periods of time were studied in the hippocampus and the raphe area by experiments with radioligands. HTR1A drug alcohol 8507391 Systemic administration of the 5 HT1A agonist ipsapirone (1.25 5.0 mg/kg) caused a dose dependent decrease in ethanol preference and intake, while the 5 HT2 antagonist ritanserin (1.25 5.0 mg/kg) and the 5 HT3 antagonists ondansetron (0.01 1.0 mg/kg) and granisetron (0.5 1.0 mg/kg) failed to alter ethanol consumption. HTR1A drug alcohol 8507391 These findings support the hypothesis that the 5 HT system is involved in the regulation of ethanol intake, with special emphasis on the involvement of the 5 HT1A receptor subtype, and may indicate that central reward mediating mechanisms are influenced.

HTR1A addiction withdrawal 7685916 Further, our data suggests that a compound's effectiveness for the treatment of social withdrawal is at least in part due to its relative affinity for binding to dopamine D1 and serotonin 5 HT1A receptors. HTR1A drug alcohol 8517886 The 5 HT1A agent buspirone reduced alcohol intake and alcohol preference in the group of medium alcohol preferring rats at doses between 0.0025 and 0.63 mg/kg. HTR1A drug cocaine 8446658 In contrast, rats receiving continuous cocaine tended to exhibit behavior consistent with 5 HT1A receptor subsensitivity. HTR1A drug cocaine 8446658 Changes in 5 HT1A receptor sensitivity may contribute to some of the anxiety and depressive symptoms exhibited by human cocaine abusers. HTR1A addiction aversion 7871000 Cross familiarisation conditioned taste aversion procedure as a method to reveal stimulus resemblance between drugs: studies on the 5 HT1A agonist 8 OHDPAT. HTR1A addiction aversion 7871000 In the present study a cross familiarisation conditioned taste aversion (CTA) paradigm was utilized to reveal stimulus resemblance between the selective 5 HT1A agonist 8 OHDPAT and a variety of serotonergic and non serotonergic drugs. HTR1A drug cocaine 7870907 Rats were trained to self administer cocaine (0.5 mg/kg/infusion) and were then pretreated with the 5 HT1A agonist 8 OH DPAT (0.125, 0.25 or 0.5 mg/kg, SC). HTR1A drug cocaine 7870907 This effect may be due to the effects at the 5 HT1A receptor, since 8 OH DPAT produced a similar effect on cocaine self administration. HTR1A drug alcohol 7748345 The anxiogenic behaviour observed 12 h after ethanol withdrawal was inhibited by the 5 HT1A partial agonist, buspirone (200 micrograms/kg s.c.), indicating that the increased 5 HT release might underlie the anxiogenic response. HTR1A addiction withdrawal 7748345 The anxiogenic behaviour observed 12 h after ethanol withdrawal was inhibited by the 5 HT1A partial agonist, buspirone (200 micrograms/kg s.c.), indicating that the increased 5 HT release might underlie the anxiogenic response. HTR1A drug alcohol 7748340 This is indicated by (a) lower contents of DA and 5 HT; (b) fewer 5 HT immunostained fibers; (c) lower densities of 5 HT1B, 5 HT2 and D2 receptors; and (d) higher densities of 5 HT1A receptors in the CNS of P rats compared to the alcohol nonpreferring NP line of rats. HTR1A drug alcohol 7748304 For example, buspirone, a 5 HT1A receptor partial agonist, reduced anxiety and alcohol craving, but not AC; a 5 HT partial agonist, m CPP, increased alcohol craving in abstinent alcoholics; modest reductions in AC were observed with a 5 HT3 antagonist, ondansetron (0.5 mg/day, but not 4 mg/day).

HTR1A drug psychedelics 1361990 Low doses of the 5 hydroxytryptamine1A (5 HT1A) antagonist NAN 190, the 5 HT2 antagonist pirenperone, and the dopamine antagonist haloperidol were able to somewhat attenuate the MDMA stimulus; however, none of these agents decreased MDMA appropriate responding to less than 46%. HTR1A drug alcohol 1335222 The effect of short term (15 days) and long term (60 days) ethanol treatment and withdrawal on agonist stimulated phosphoinositide (Pl) hydrolysis, serotonin receptor subtypes (5HT1A and 5HT2), and alpha 1 adrenergic receptors were studied in rat cerebral cortex.

HTR1A drug alcohol 1335222 We also observed that long term ethanol treatment had no significant effect on Bmax and KD of 5HT2, 5HT1A, and alpha 1 adrenergic receptors, as well as NE and A23187 stimulated [3H] IP1 formation, but significantly decreased the 5HT stimulated [3H] IP1 formation in rat cerebral cortex.

HTR1A drug benzodiazepine 1356807 It is concluded that the reduction in aversive responding caused by pharmacological manipulation at the benzodiazepine, 5 HT receptor subtypes 5 HT1A, 5 HT1C/5 HT2 and 5 HT3 (but not at the cholecystokin CCKA or angiotensin receptors or inhibition of angiotensin converting enzyme) can be inhibited by R(+) and S( ) zacopride.

HTR1A drug cocaine 1385662 Furthermore, several brain areas that contain either cell bodies (DR) or terminals for 5 HT (medial and sulcal prefrontal cortex, frontal cortex) showed cocaine induced elevations in [3H]imipramine labeled 5 HT uptake sites, while [3H] 8 OHDPAT labeled 5 HT1A receptors were decreased only in the central medial amygdala. HTR1A drug cocaine 1584831 In a recent study, we reported that the (+/ ) 1 (2,5 dimethoxy 4 iodophenyl) 2 aminopropane HCl (DOI) induced HTR was dose dependently reduced by cocaine via indirect stimulation of serotonergic 5 HT1A and adrenergic alpha 2 receptors.

HTR1A drug alcohol 1353126 Voluntary intake of alcohol is attenuated by ipsapirone in mice and role of 5 HT1A receptor. HTR1A drug alcohol 1353126 The aim of this study is to examine the effect of ipsapirone, which is a specific 5 HT1A agonist with a pyrimidinylpiperazine structure, on alcohol consumption in mice (C57BL/6J) by a voluntary alcohol intake paradigm.

HTR1A addiction reward 1351303 Treatment with the 5 HT1A agonist flesinoxan (0.1 3.0 mg/kg) also dose dependently decreased response rates while at the same time increasing reinforcement rates. HTR1A drug opioid 1839965 After 15 min of exposure to the presence of an experienced predatory cat, mice displayed a naloxone (1.0 mg/kg) sensitive opioid mediated analgesic response, while after a brief 30 s exposure to the cat mice displayed a lower amplitude, relatively brief, non opioid analgesia that was insensitive to naloxone and blocked by the serotonin 1A (5 HT1A) agonist, 8 hydroxy 2 (di n propylamino)tetralin.

HTR1A drug benzodiazepine 1661879 Such hyperactivity was significantly blocked after 10 days of repeated administration of diazepam (DZP), tandospirone (SM 3997; SM), a 5 HT1A anxiolytic, and nitrendipene (Nit), a Ca antagonist. HTR1A drug opioid 1672380 High efficacy 5 HT1A agonists attenuate morphine induced antinociception in mice in a competitive like manner. HTR1A drug opioid 1672380 The selective 5 HT1A agonist, (+ ) 8 hydroxy diprolaminotetralin HBr (8 OH DPAT), dose dependently antagonized morphine induced antinociception (MIA) without affecting the latency to respond when applied alone.

HTR1A drug alcohol 1726986 Neurochemical data indicate that high alcohol seeking behavior (when compared with data from rats with low alcohol seeking characteristics) is associated with (a) lower contents of 5 HT in certain limbic regions, e.g., n. accumbens (Acb), frontal cortex, (b) a lower content of DA in the Acb, and (c) higher densities of 5 HT1A receptors in certain limbic regions, e.g., cerebral cortex. HTR1A addiction relapse 1726986 Neurochemical data indicate that high alcohol seeking behavior (when compared with data from rats with low alcohol seeking characteristics) is associated with (a) lower contents of 5 HT in certain limbic regions, e.g., n. accumbens (Acb), frontal cortex, (b) a lower content of DA in the Acb, and (c) higher densities of 5 HT1A receptors in certain limbic regions, e.g., cerebral cortex.

HTR1A drug opioid 2144490 The effects of morphine tolerance dependence and abstinence on 5 HT1A receptors in brain regions and spinal cord of the rat were determined. HTR1A addiction dependence 2144490 The effects of morphine tolerance dependence and abstinence on 5 HT1A receptors in brain regions and spinal cord of the rat were determined. HTR1A drug opioid 2144490 In morphine and placebo tolerant dependent rats the binding of [3H]DPAT to 5 HT1A receptors in brain regions and spinal cord did not differ. HTR1A drug opioid 2144490 Since DPAT is believed to have a major action on the presynaptic 5 HT neurons, it is concluded that in morphine abstinent rats 5 HT1A receptors are down regulated in hypothalamus, but in morphine tolerant dependent rats they are unaffected. HTR1A drug alcohol 2184832 Neurochemical data indicate that high alcohol seeking behavior (when compared with data from rats with low alcohol seeking characteristics) is associated with: a) lower (10 20%; p less than 0.05) contents of 5 HT in certain limbic regions (e.g., nucleus accumbens, frontal cortex, hypothalamus and hippocampus); b) a lower (10 15%; p less than 0.05) content of DA in the nucleus accumbens; c) higher (20 35%; p less than 0.05) densities of 5 HT1A binding sites in some limbic regions (e.g., medial nucleus accumbens, medial prefrontal cortex and ventral hippocampus); and d) a greater (20 50%) density of GABA axon terminals in the nucleus accumbens.

HTR1A drug benzodiazepine 1975107 The benzodiazepine diazepam (5 mg/kg) also failed to reduce immobility time, suggesting that anxiolytic properties of 5 HT1A agonists did not mediate this behavioral effect. HTR1A drug benzodiazepine 2574684 The effects of several 5 HT1A agonists and excitatory amino acid antagonists were compared to the standard benzodiazepines, diazepam and chlordiazepoxide (CDP) in two assays predictive of anxiolytic activity, the social interaction and elevated plus maze procedures. HTR1A addiction reward 2746512 It is likely that the hypoactivity and PRL responses of m CPP are mediated by 5 HT1B receptors, and the cardiodepressive effects by 5 HT1A receptors.

CREB1 addiction dependence 22580231 cAMP response element binding protein(CREB) and the cAMP cascade play a pivotal role in the opiate dependence. CREB1 drug opioid 22580231 In cells treated with chronic morphine, the expression of CREB, adenylyl cyclase (AC) and protein kinase A (PKA) were increased, while in cells infected with LV CREB3, treated with chronic morphine treatment failed to increase the expressions of CREB and AC. CREB1 drug opioid 22580231 Consistently, in the rat model for chronic morphine treatment, morphine increased the expression of CREB, AC and PKA in LC neurons. CREB1 drug opioid 22580231 In conclusion, the lentiviral vectors expressing CREB shRNA inhibited the increase of CREB and AC expression induced by chronic morphine treatment both in vivo and in vitro.

CREB1 drug nicotine 22330674 The present experiments examined the effects of exposure to variable stress on nicotine induced locomotor activation, cAMP response element binding protein (CREB) and extracellular signal regulated kinase (ERK) activity and nicotine intravenous self administration in rats. CREB1 drug nicotine 22330674 Repeated variable stress caused a sensitized motor response to a single challenge of nicotine and decreased CREB in the nucleus accumbens. CREB1 drug nicotine 22301350 We examined the hypothesis that adolescent animals who exhibit higher novel stimulus reactivity, exhibit greater locomotor activity in response to nicotine than adolescents who exhibit lower novel stimulus reactivity, and that this difference is associated with alterations in CREB expression and activity in the ventral striatum (vStr) and prefrontal cortex (PFC). CREB1 drug nicotine 22301350 Further, HLA adolescents exhibited lower CREB activity in the vStr than LLA adolescents and this difference was attenuated by repeated exposure to high, but not low doses of nicotine.

CREB1 addiction intoxication 22269225 We examined the effects of ethanol on the phosphorylation of CREB in hepatocytes, and in vivo in rat liver after chronic ethanol binge. CREB1 drug alcohol 22269225 Treatment of hepatocytes with ethanol caused increased phosphorylation of p38 MAPK (mitogen activated protein kinase), MSK 1 (mitogen and stress activated kinase) and CREB in the nuclear compartment without activation of ERK1/2 (extracellular regulated kinase); whereas angiotensin II induced activation of CREB was accompanied by activation of ERK1/2.

CREB1 drug nicotine 22086359 CREB phosphorylation at Ser133 is enhanced by drugs of abuse, including nicotine. CREB1 addiction addiction 22086359 Dynorphin (Dyn) contributes to the addictive process and its precursor gene prodynorphin (PD) is regulated by CREB. CREB1 drug nicotine 22086359 These studies investigated PD transcription in mice acutely treated with nicotine, determined the role of CREB, and characterized the receptors involved. CREB1 drug nicotine 22086359 Acute nicotine increased adenylyl cyclase activity, cAMP, and pCREB Ser133 levels in striatum and enhanced CREB binding to CRE elements (DynCREs) of the PD promoter, preferentially DynCRE3. CREB1 drug nicotine 22086359 Our findings suggest that nicotine regulates PD expression in striatum at the transcriptional level and CREB is involved.

CREB1 drug cocaine 22072694 Here, we used viral mediated gene transfer to produce short and long term regulation of CREB activity in NAc shell of rats engaging in volitional cocaine self administration. CREB1 drug cocaine 22072694 Increasing CREB expression in NAc shell markedly enhanced cocaine reinforcement of self administration behavior, as indicated by leftward (long term) and upward (short term) shifts in fixed ratio dose response curves. CREB1 addiction reward 22072694 Increasing CREB expression in NAc shell markedly enhanced cocaine reinforcement of self administration behavior, as indicated by leftward (long term) and upward (short term) shifts in fixed ratio dose response curves. CREB1 drug cocaine 22072694 CREB also increased the effort exerted by rats to obtain cocaine on more demanding progressive ratio schedules, an effect highly correlated with viral induced modulation of BDNF protein in the NAc shell. CREB1 drug cocaine 22072694 CREB enhanced cocaine reinforcement when expressed either throughout acquisition of self administration or when expression was limited to postacquisition tests, indicating a direct effect of CREB independent of reinforcement related learning.

CREB1 addiction withdrawal 22072694 Together, these findings indicate that CREB activity in NAc shell increases the motivation for cocaine during active self administration or after withdrawal from cocaine. CREB1 drug cocaine 22043863 Cocaine induced changes in BDNF mRNA were associated with increased acetylation of histone 3 and binding of CREB binding protein to exon I containing promoters in the VTA. CREB1 drug cocaine 21886557 These changes are considered as consequences of cocaine induced molecular adaptation such as CREB and c Fos. CREB1 drug cocaine 21886557 In addition, LQ inhibited CREB phosphorylation and c Fos expression in the striatum and the nucleus accumbens induced by acute cocaine. CREB1 drug cocaine 21867882 This resilience was mediated, in part, through repression of BDNF TrkB CREB signaling, which was induced after repeated cocaine or stress. CREB1 drug cocaine 21812869 Chronic cocaine self administration modulates ERK1/2 and CREB responses to dopamine receptor agonists in striatal slices. CREB1 drug cocaine 21812869 We hypothesized that chronic cocaine self administration could influence dopamine D1 and D2 receptor activation of extracellular signal regulated protein kinase 1 and 2 (ERK1/2) and cyclic adenosine monophosphate response element binding protein (CREB) phosphorylation. CREB1 drug cocaine 21812869 Cocaine self administration also reduced D1R agonist induced CREB phosphorylation in striatal slices, suggesting a downregulation of D1R signaling. CREB1 drug cocaine 21812869 In contrast, surprisingly, cocaine self administration strongly potentiated D2R agonist induced CREB phosphorylation selectively in the NAc portion of the slices. CREB1 drug cocaine 21812869 Our finding that selected cellular D2R responses to CREB were strengthened by cocaine self administration could be relevant to understand how dopaminergic receptors participate in cocaine induced behaviors. CREB1 drug opioid 21782156 Thus, c Fos, FosB/ΔFosB and P CREB immunoreactive profiles were quantified in the rat CPu after either acute or continuous (6 day) administration of morphine and/or PD168,077. CREB1 drug opioid 21782156 Interestingly, at some time points, combined treatment with morphine and PD168,077 substantially increased c Fos, FosB/ΔFosB and P CREB expression.

CREB1 drug cocaine 21632938 Our data are consistent with a cellular cascade whereby cocaine induced activation of CREB promotes CREB dependent transcription of NR2B and synaptic incorporation of NR2B containing NMDARs, which generates new silent synapses within the NAc. CREB1 drug cocaine 21632938 We propose that cocaine induced activation of CREB and generation of new silent synapses may serve as key cellular events mediating cocaine induced locomotor sensitization.

CREB1 drug nicotine 21420997 In the nicotine treated groups, the levels of phosphorylated CREB and ERK2 in the PFC were increased in HIV 1Tg rats, but decreased in F344 animals. CREB1 drug nicotine 21420997 Moreover, repeated nicotine administration reduced phosphorylated ERK2 in the VTA of HIV 1Tg rats and in the NAc of F344 rats, but had no effect on phosphorylated CREB, indicating a region specific change of intracellular signaling. CREB1 drug nicotine 21420997 These results demonstrate that HIV 1 viral proteins produce differences in basal and nicotine induced alterations in CREB and ERK signaling that may contribute to the alteration in psychomotor sensitization. CREB1 addiction sensitization 21420997 These results demonstrate that HIV 1 viral proteins produce differences in basal and nicotine induced alterations in CREB and ERK signaling that may contribute to the alteration in psychomotor sensitization. CREB1 drug nicotine 21420997 Thus, HIV 1 positive smokers are possibly more vulnerable to alterations in CREB and ERK signaling and this has implications for motivated behavior, including tobacco smoking, in HIV 1 positive individuals who self administer nicotine. CREB1 addiction aversion 21414930 Here we show in rats that stress (footshock) activates the transcription factor cAMP response element binding protein (CREB) within the nucleus accumbens shell (NAS), a brain area involved in encoding reward and aversion. CREB1 addiction reward 21414930 Here we show in rats that stress (footshock) activates the transcription factor cAMP response element binding protein (CREB) within the nucleus accumbens shell (NAS), a brain area involved in encoding reward and aversion. CREB1 addiction reward 21414930 Elevated CREB produced increases in intracranial self stimulation thresholds, a depressive like sign reflecting anhedonia (decreased sensitivity to reward), whereas disruption of CREB function by expression of a dominant negative CREB had the opposite effect. CREB1 drug opioid 21414930 To mimic downstream effects of CREB activation on expression of the opioid peptide dynorphin, we microinjected the κ opioid receptor (KOR) agonist U50,488 directly into the NAS.

CREB1 addiction reward 21295078 The results indicated a significant increase in level of phosphorylated CREB (P<0.01) in VTA, and PFC (P<0.05), during LH stimulation induced CPP, while its level decreased in hippocampus (P<0.05). CREB1 addiction reward 21295078 Our findings suggest that studying the intracellular signals and their changes, such as phosphorylated CREB, can elucidate a functional relationship between LH and other brain structures involved in reward processing in rats. CREB1 drug cocaine 21248106 Vehicle infused rats with a cocaine SA history showed significant decreases in ERK and cyclic AMP response element binding protein (CREB), but not Akt, phosphorylation after the final cocaine SA session that were reversed by intra dmPFC BDNF. CREB1 drug cocaine 21248106 Additionally, BDNF's ability to normalize cocaine mediated decreases in ERK and CREB phosphorylation was blocked by U0126, demonstrating that ERK/MAPK activation mediated the behavioral effects.

CREB1 drug cocaine 21138621 Our findings demonstrate that the amygdala transcriptome was altered by CREB deficiency more than by previous cocaine experience, with an over representation of genes involved in the immune response. CREB1 drug cocaine 21138621 However, a subset of genes involved in stress and immune response demonstrated a drug×genotype interaction, indicating that cocaine produces different long term alterations in gene expression depending on the presence or absence of CREB.

CREB1 drug nicotine 21070506 We recently showed that the expression and phosphorylation of cyclic adenosine monophosphate response element (CRE) binding protein (CREB) in human buffy coat were associated with smoking behavior. CREB1 drug nicotine 21070506 Because ERK1/2 is known to effect phosphorylation of CREB, the aim of the present study was to further elucidate whether cigarette smoking leads to alterations in terms of ERK1/2 in human buffy coat as well. CREB1 drug opioid 21068718 Microinjection of HSV vector expressing sTNFR into the PAG also significantly reduced the phosphorylation of both ERK1/2 and CREB, and reduced Fos immunoreactivity in neurons of the PAG following naloxone precipitated withdrawal.

CREB1 drug amphetamine 21057772 Extracellular signal regulated kinase (ERK), cAMP response element binding protein (CREB), and protein kinase B (PKB or Akt) in the striatum are differentially activated by acute and repeated amphetamine (AMPH) administration. CREB1 drug amphetamine 21057772 The role of the D1 and D2 class of dopamine receptors in the differential phosphorylation of striatal ERK, CREB, Thr308 Akt and Ser473 Akt and the expression of behavioral sensitization induced by AMPH challenge in AMPH pretreated rats were determined. CREB1 addiction sensitization 21057772 The role of the D1 and D2 class of dopamine receptors in the differential phosphorylation of striatal ERK, CREB, Thr308 Akt and Ser473 Akt and the expression of behavioral sensitization induced by AMPH challenge in AMPH pretreated rats were determined. CREB1 drug amphetamine 21057772 SCH23390, but not eticlopride, significantly decreased ERK, CREB, and Thr308 Akt phosphorylation in the striatum 15 min, and ERK and CREB phosphorylation 2 h, after AMPH challenge in AMPH sensitized rats. CREB1 drug opioid 20837544 This increased excitability was mediated by direct activation of opioid receptors and up regulation of the cAMP pathway and accompanied by increased cAMP response element binding protein (CREB) activity. CREB1 drug opioid 20837544 Overexpression of a dominant negative CREB mutant blocked the increase in LC excitability induced by morphine or cAMP pathway activation. CREB1 drug opioid 20837544 Furthermore, the ability of morphine or CREB overexpression to up regulate LC firing was blocked by knockout of the CREB target adenylyl cyclase 8. CREB1 drug opioid 20837544 Together, these findings provide direct evidence that prolonged exposure to morphine induces homeostatic plasticity intrinsic to LC neurons, involving up regulation of the cAMP CREB signaling pathway, which then enhances LC neuronal excitability. CREB1 drug opioid 20731628 The levels of phosphorylated DARPP32 (Thr34) and phosphorylated CREB (Ser133) were increased in the ACG of rats that had maintained the morphine induced place preference, whereas the increases of these levels induced by morphine were blocked by pre treatment of a selective dopamine D1 receptor antagonist SCH23390. CREB1 drug opioid 20731628 The activation of DARPP32 and CREB through dopamine D1 receptors in the ACG could be implicated in the maintenance of μ opioid induced place preference.

CREB1 addiction withdrawal 20367754 We found that the enhanced expression of tyrosine hydroxylase normally observed during withdrawal was attenuated in CREB/CREM mutants. CREB1 drug opioid 20367754 We conclude by a specific genetic approach that the withdrawal associated hyperexcitability of noradrenergic neurons depends on CREB/CREM activity in these neurons, but does not mediate several behavioral signs of morphine withdrawal.

In contrast, the score of the State and Trait Anxiety Inventory, total CREB and mRNA CREB were not significantly different. CREB1 drug nicotine 20047710 Multiple regression analysis revealed a significant relation between the number of cigarettes smoked daily (R2=0.143, p=0.023), the Fagerström Test for Nicotine Dependence score (R2=0.145, p=0.022) and the expression of CREB.

CREB1 drug opioid 19897079 Our results indicate that heroin significantly upregulated both D1R and DARPP 32 gene expression, and that DARPP 32 silencing in the NHA cells resulted in the significant modulation of the activity of downstream effector molecules such as PP 1, ERK, and CREB which are known to play an important role in opiate abuse induced changes in long term neural plasticity.

CREB1 addiction reward 19429161 Present findings demonstrate: (1) the hippocampus is vulnerable to the direct chemical effect of anandamide and R(+) methanandamide in isolation of synaptic influences from the midbrain reward neurons, and (2) the effect of R(+) methanandamide is cumulative as evidenced by the sustained elevation of CREB activities in response to a chronic dosage that is too low and thus fails to exert any acute effect.

CREB1 drug nicotine 19077117 In contrast to control mice, transgenic mice with low level beta2* nAChR expression in the VTA showed no increase in overall levels of cyclic AMP response element binding protein (CREB) but did show an increase in CREB phosphorylation in response to exposure to a nicotine paired chamber. CREB1 drug nicotine 19077117 Thus, CREB activation in the absence of regulation of total CREB levels during place preference testing was not sufficient to support nicotine place preference in beta2 trangenic mice. CREB1 drug opioid 19071107 Furthermore, oxycodone (2.5 mg/kg) induced the increased phosphorylation of CREB and ERK in nucleus accumbens and hippocampus, but not in prefrontal cortex. CREB1 drug opioid 19071107 All these results suggest that l THP can inhibit oxycodone induced psychological dependence by affecting phosphorylation of CREB and ERK in nucleus accumbens and hippocampus of rats.

CREB1 addiction reward 18945553 To evaluate signaling events that correlate with this behavior, brain tissue of these rats were dissected for immunoblot assays of extracellular signal regulated kinase (ERK) and a transcriptional regulator, cAMP response element binding protein (CREB) after the CPP test.

CREB1 drug amphetamine 18848971 Conversely, repeated treatment with BA or VPA produced amphetamine like effects: enhanced cAMP responsive element binding protein (CREB) phosphorylation at Ser(133) position and increased DeltaFosB protein levels in the striatum. CREB1 drug amphetamine 18848971 Furthermore, co administration of BA or VPA with amphetamine produced additive effects on histone H4 acetylation as well as CREB phosphorylation in the striatum. CREB1 drug amphetamine 18848971 Finally, the additive effect of VPA/BA and amphetamine on histone H4 acetylation, phosphorylated CREB, and DeltaFosB was associated with potentiated amphetamine induced locomotor activity. CREB1 addiction sensitization 18848971 Thus, HDACi may interact additively with psychostimulants at both histone acetylation and CREB phosphorylation through the CREB:HDAC protein complex in the striatum to modulate DeltaFosB protein levels and psychomotor behavioral sensitization. CREB1 drug opioid 18771713 Therefore, we studied the effects of short term (24 h) and long term (7 day) morphine treatment on the expression of hypothalamic PC1/3 and PC2 and levels of phosphorylated cyclic AMP response element binding protein (P CREB). CREB1 drug opioid 18771713 While short term morphine exposure down regulated, long term morphine exposure up regulated P CREB, PC1/3 and PC2 protein levels in the rat hypothalamus as determined by Western blot analysis.

CREB1 drug cocaine 18554320 Enhanced CREB and DARPP 32 phosphorylation in the nucleus accumbens and CREB, ERK, and GluR1 phosphorylation in the dorsal hippocampus is associated with cocaine conditioned place preference behavior. CREB1 drug cocaine 18554320 To better understand the mechanism of cocaine conditioned place preference we have used western blot analysis to examine changes in phosphorylation of cAMP response element binding protein (CREB), dopamine and cyclic AMP regulated phosphoprotein 32 (DARPP 32), extracellular signal regulated kinase (ERK) and GluR1, key molecular substrates altered by cocaine, in the nucleus accumbens (NAc) and dorsal hippocampus (DHC) of C57BL/6 mice. CREB1 drug cocaine 18554320 Our studies revealed that re exposing mice to an environment in which they were previously given cocaine resulted in increased levels of Ser133 phospho CREB and Thr34 phospho DARPP 32 with a corresponding decrease in Thr75 phospho DARPP 32 in the NAc. CREB1 addiction reward 18554320 These data suggest that the formation of contextual drug reward associations involves recruitment of the DHC NAc circuit with activation of the DARPP 32/CREB pathway in the NAc and the ERK/CREB pathway in the DHC. CREB1 drug alcohol 18385331 We found that the anxiolytic effects produced by acute alcohol were associated with a decrease in histone deacetylase (HDAC) activity and increases in acetylation of histones (H3 and H4), levels of CREB (cAMP responsive element binding) binding protein (CBP), and neuropeptide Y (NPY) expression in the amygdaloid brain regions of rats. CREB1 drug alcohol 18322102 Here, we report that the anxiolytic effects of acute ethanol were associated with increased brain derived neurotrophic factor (BDNF) and tyrosine kinase B (trkB) expression, increased phosphorylation of extracellular signal regulated kinases 1/2 (Erk1/2), Elk 1, and cAMP responsive element binding protein (CREB), increased Arc expression, and increased dendritic spine density (DSD) in both the central amygdala (CeA) and medial amygdala (MeA) but not in the basolateral amygdala (BLA) of rats. CREB1 drug alcohol 18322102 Conversely, the anxiogenic effects of withdrawal after long term ethanol exposure were associated with decreased BDNF and trkB expression, decreased phosphorylation of Erk1/2, Elk 1, and CREB, decreased Arc expression, and decreased DSD in both the CeA and MeA but not in the BLA of rats.

CREB1 addiction addiction 18261852 The development of addiction related phenotypes is known to be modulated by regulation of glutamate receptors, as well as activation of transcription factors including cAMP response element binding protein (CREB), in the NAc. CREB1 drug nicotine 18261852 We investigated the effects of nicotine pre exposure on nicotine preference and levels of GluR1/2 and CREB in the mesolimbic system in male mice C57BL/6J and BALB/c inbred mice. CREB1 drug nicotine 18261852 In addition, alterations in CREB and GluR1 levels are not sufficient to explain preference for nicotine in a 2 bottle choice paradigm. CREB1 drug cocaine 18055458 Furthermore, mimicking the effect of CREB by pharmacological enhancement of NMDAR function in the NAc in vivo suppressed novelty and cocaine elicited locomotor activity. CREB1 drug amphetamine 18000809 No significant genotype difference in the effects of d amphetamine on MAPK phosphorylation events within the ventral striatum, phosphorylation at Ser(897) of the NR1 subunit of the NMDA receptor or Ca(2+) and cyclic AMP response element binding protein (CREB) at Ser(133) in the frontal cortex was detected. CREB1 drug opioid 17957220 In addition, morphine induced ERK1/2 phosphorylation was increased in the VTA of both wild type and GKO mice, but only the GKO mice showed increases in ERK1/2 and CREB phosphorylation in the amygdala or nucleus accumbens. CREB1 drug cocaine 17897358 NMDA induced activation of the NMDA receptor R1 subunit (NR1), Ca(2+)/calmodulin dependent protein kinase II and the cAMP response element binding protein (CREB), and cocaine induced CREB activation in the CPu are also oppositely regulated by dopamine D(1) and D(3) receptors. CREB1 drug cocaine 17897358 Finally, the blockade of NMDA receptor reduces cocaine induced ERK activation, and inhibits phosphorylation of NR1, Ca(2+)/calmodulin dependent protein kinase II, and CREB, while inhibiting ERK activation attenuates cocaine induced CREB phosphorylation in the CPu.

CREB1 addiction withdrawal 17324065 CREB dependent gene transcription, which may underlie long lasting drug induced changes in behavior and the subjective effects of cocaine, varies depending on the stage of drug exposure or withdrawal and the cell population involved. CREB1 drug cocaine 17324065 Using immunohistochemistry, the authors analyzed changes in CREB phosphorylation in the NAc after 5 days of cocaine, a short or long drug free period, and a subsequent challenge injection. CREB1 drug cocaine 17324065 Repeated cocaine resulted in CREB phosphorylation in all analyzed subregions of the NAc excluding the most ventrolateral region of the shell 2 weeks after cessation of repeated cocaine, but rats challenged after 2 drug free days yielded a more localized activation of CREB in the 3 most dorsomedial zones of the shell. CREB1 drug cocaine 17324065 The temporal and anatomical determinants of cocaine induced CREB activity may indicate functional differences among NAc shell subregions and suggest the involvement of CREB in early and late cocaine effects.

CREB1 addiction withdrawal 16951039 pCREB (activated CREB) was elevated in the frontal cortex at 3 days withdrawal, but not at 14 days. CREB1 drug opioid 16914643 Furthermore, the significant increase in phosphorylated cAMP response element binding protein (CREB) staining in ventral tegmental area induced by long term morphine treatment was not evident in DKO mice, suggesting that CREB activation by morphine requires cAMP generated by AC1 and AC8.

CREB1 drug opioid 16775132 Surprisingly, SKF 82958 increased P GluR1, but not P CREB, in the NAc, and naloxone reduced SKF 82958 mediated P GluR1 induction specifically in morphine dependent rats. CREB1 addiction aversion 16775132 Together, these results confirm that aversive treatments can increase CREB function in the NAc. CREB1 addiction dependence 16775132 Furthermore, they suggest a dependence associated shift in the molecular mechanisms that regulate the consequences of D1 receptor stimulation, favoring activation of GluR1 rather than CREB. CREB1 drug cocaine 16710312 Chronic cocaine induces the accumulation of the transcription factor deltaFosB and upregulates cAMP response element binding protein (CREB) and dopamine and cAMP regulated phosphoprotein of 32 kDa (DARPP 32). CREB1 drug opioid 16641242 The transcription factor cAMP response element binding protein (CREB) is implicated in mediating the actions of chronic morphine in the locus ceruleus (LC), but direct evidence to support such a role is limited.

CREB1 drug cocaine 16046859 Augmented constitutive CREB expression in the nucleus accumbens and striatum may contribute to the altered behavioral response to cocaine of adult mice exposed to cocaine in utero. CREB1 drug cocaine 16046859 Tissue samples of the nucleus accumbens (NAc) and striatum (Str) of all four prenatal treatment groups were examined to determine whether alterations in the transcription factor CREB or glutamate receptor subunit, GluR1, induced by prenatal cocaine treatment may have contributed to the altered behavioral responses. CREB1 drug cocaine 16046859 Such alterations in constitutive CREB levels may contribute to some of the behavioral differences reported in adult mice exposed to cocaine in utero.

CREB1 drug opioid 15680959 The behavioral differences in response to morphine seen in CREB(alphaDelta) mutant mice are not due to changes in mu opioid receptor (MOR) mRNA expression, as the CREB deletion has no effect on baseline MOR mRNA in three of the brain regions involved in mediating these behaviors: the ventral tegmental area (VTA), nucleus accumbens (NAc), and hypothalamus. CREB1 drug opioid 15680959 These data demonstrate that at low doses, deficits in morphine induced changes in CREB deficient mice are limited to reward and thermoregulation.

CREB1 drug alcohol 15163695 It was also found that CREB deficient (+/ ) mice displayed more anxiety like behaviors and that acute ethanol exposure produced anxiolytic effects and significantly increased protein levels of p CREB and NPY in the central and medial but not in the basolateral amygdala of wild type mice, but these effects are attenuated in CREB deficient mice compared with wild type mice. CREB1 drug alcohol 15163695 These results provide the first direct evidence that a haplodeficiency of the CREB gene is associated with increased alcohol drinking behaviors. CREB1 drug alcohol 15163695 Furthermore, alcohol drinking and anxiety like behaviors in CREB haplodeficient mice may possibly be related to decreased expression of NPY and BDNF in the brains of these mice.

CREB1 drug alcohol 12967770 Anxiety and alcohol abuse disorders: a common role for CREB and its target, the neuropeptide Y gene. CREB1 drug alcohol 12967770 Here, I propose that cAMP response element binding protein (CREB) has a role in anxiety and alcohol drinking behaviors. CREB1 drug alcohol 12967770 The CREB gene transcription factor regulates the expression of the gene encoding neuropeptide Y (NPY), and decreased concentrations of NPY are implicated in anxiety and alcohol drinking behaviors. CREB1 drug alcohol 12967770 Therefore, decreased function of CREB in the central nucleus of the amygdala might regulate anxiety and alcohol intake via decreased expression of NPY, and might provide a common link between anxiety and alcohol abuse disorders. CREB1 drug alcohol 12967770 I also suggest that, via CREB, NPY might interact with other CREB target genes, such as the gene encoding brain derived neurotrophic factor, and that this CREB mediated interaction might be important in the regulation of anxiety and alcohol drinking behaviors.

CREB1 drug cocaine 12716423 The present results indicate that selective alterations of CREB and certain ionotropic glutamate receptor (iGluR) subtypes appear to be associated with chronic cocaine use in humans in a region specific manner.

CREB1 drug alcohol 12715102 In contrast, chronic intake of ethanol solution obviously decreased the expression of p CREB protein compared to the control rats. CREB1 drug alcohol 12715102 The results suggest that an acute ethanol administration led to an increase in the phosphorylation of CREB in the nucleus accumbens, but chronic ethanol administration produced a decrement, which is possibly one of the molecular mechanisms of alcohol dependence.

CREB1 drug alcohol 9581644 This study examined influences of ethanol exposure on phosphorylation of cAMP response element binding protein (CREB) and CRE binding activity in the striatum of rats. CREB1 addiction intoxication 9581644 The phosphorylated form of CREB increased 180% during acute intoxication, compared to sham conditions. CREB1 drug alcohol 9581644 After chronic ethanol exposure, induction of CREB phosphorylation by an acute ethanol challenge was markedly attenuated (50%) compared with acute ethanol exposure in the pair fed condition.

CREB1 drug opioid 8558448 Regulation of CREB expression: in vivo evidence for a functional role in morphine action in the nucleus accumbens. CREB1 drug opioid 8558448 Chronic, but not acute, morphine administration was found to decrease levels of CREB immunoreactivity in the NAc, an effect not seen in other brain regions studied. CREB1 drug opioid 8558448 It was found that the antisense oligonucleotide induced reduction in CREB levels mimicked the effect of morphine on certain, but not all, cAMP pathway proteins in this brain region, whereas a large number of other signal transduction proteins tested were unaffected by this treatment. CREB1 drug opioid 8558448 Our results support a role for CREB in autoregulation of the cAMP pathway in the nervous system, as well as in mediating some of the effects of morphine on this signaling pathway in the NAc. CREB1 addiction withdrawal 7476883 To determine whether this withdrawal induced increase in cAMP modifies gene expression, we studied phosphorylation of the cAMP response element binding protein (CREB) and expression of the c fos gene, known to contain a cAMP response element, in NG108 15 cells after abrupt withdrawal from chronic treatment with carbachol. CREB1 addiction withdrawal 7476883 In cells treated with carbachol for 48 hr, induction of withdrawal with the muscarinic antagonist atropine led to a small increase in intracellular cAMP concentration but an 11.6 fold increase in the phosphorylation of CREB and a 3.4 fold increase in accumulation of c fos mRNA. CREB1 addiction withdrawal 7476883 The adenylyl cyclase inhibitor 2',5' dideoxyadenosine, which attenuated the chronic carbachol induced increase in cAMP concentration, prevented the increased phosphorylation of CREB and the enhanced accumulation of c fos mRNA during atropine induced withdrawal.

CREB1 drug amphetamine 8083758 Here we report that amphetamine induces phosphorylation of transcription factor cAMP response element binding protein (CREB) in rat striatum in vivo and that dopamine D1 receptor stimulation induces phosphorylation of CREB within specific complexes bound to cAMP regulatory elements. CREB1 drug amphetamine 8083758 In addition, we show by antisense injection that CREB is necessary for c fos induction by amphetamine in vivo. CREB1 drug amphetamine 8083758 Since CREB has been implicated in the activation of a number of immediate early genes as well as several neuropeptide genes, CREB phosphorylation may be an important early nuclear event mediating long term consequences of amphetamine administration.

CREB1 drug opioid 1531356 Regulation of cyclic AMP response element binding protein (CREB) phosphorylation by acute and chronic morphine in the rat locus coeruleus. CREB1 drug opioid 1531356 To understand better the mechanism by which opiates produce these intracellular adaptations, we studied morphine regulation of the state of phosphorylation of cyclic AMP response element binding protein (CREB), a transcription factor that mediates some of the effects of the cyclic AMP system on gene expression. CREB1 drug opioid 1531356 We show here, by use of a back phosphorylation and immunoprecipitation procedure, that acute morphine decreases the state of phosphorylation of CREB, an effect that becomes completely attenuated after chronic morphine administration. CREB1 addiction withdrawal 1531356 In contrast, acute precipitation of opiate withdrawal, via administration of an opiate receptor antagonist, increases the phosphorylation state of CREB. CREB1 addiction addiction 1531356 Such regulation of CREB phosphorylation could be part of the molecular pathway by which opiates produce changes in gene expression that lead to addiction.

DRD2 addiction reward 21968930 These animals presented prominent changes in the nucleus accumbens (NAcc), a key component of the mesolimbic reward circuitry; specifically, cell numbers and dopamine (DA) levels were significantly reduced, whereas DA receptor 2 (Drd2) mRNA expression levels were markedly upregulated in the NAcc. DRD2 drug opioid 21968930 Interestingly, repeated morphine exposure significantly downregulated Drd2 expression in iuGC exposed animals, in parallel with increased DNA methylation of the Drd2 gene. DRD2 drug opioid 21968930 Administration of a therapeutic dose of L dopa reverted the hypodopaminergic state in the NAcc of iuGC animals, normalized Drd2 expression and prevented morphine induced hypermethylation of the Drd2 promoter. DRD2 addiction reward 21955259 Additionally, striatal dopamine D2 receptor (DRD2) availability has been implicated in reward function. DRD2 drug cannabinoid 21955259 This study shows that chronic treatment of rats with rimonabant (1.0 and 3.0 mg/kg/day) dose dependently increased DRD2 availability in the dorsal striatum (14 and 23%) compared with vehicle.

DRD2 addiction dependence 16751215 Numerous studies of the relationship between the TaqIA DRD2 A1 allele and alcohol dependence have been performed and many of these have shown an association whereas others have not (Noble, 2003). DRD2 drug alcohol 16751215 In case control studies it has been estimated that to detect the role of genes with small effect size of approximately 2, which is in the range of the DRD2 A1 allele alcoholism relationship, case control sets of 300 400 subjects are necessary (Noble, 2003). DRD2 drug alcohol 16751215 In the present study, in which the TaqI A1/A2 DRD2 polymorphism was in Hardy Weinberg equilibrium in the patient group and the two control groups, we found that the TaqI DRD2 A1/A2 genotype frequency differed significantly between the alcohol dependent group and both the total and screened control groups. DRD2 drug alcohol 16751215 Furthermore, the TaqI DRD2 A1 allele frequency was significantly overrepresented in the alcohol dependent subjects as compared with both the total and screened control groups. DRD2 drug alcohol 16751215 Consequently, the findings in this study lend further support to the notion of an association between the DRD2 A1 allele and alcohol dependence, although the effect size of the DRD2 A1 allele is small.

DRD2 drug nicotine 16402081 We have previously demonstrated that a functional dopamine D2 receptor promoter variant (DRD2 141 Ins/Del) predicts response to nicotine replacement therapy (NRT). DRD2 drug nicotine 16402081 The results indicate a statistically significant interaction effect of DRD2 141 and FREQ genotypes on abstinence at the end of the NRT treatment phase; 62% of the smokers with at least one copy of the DRD2 141 Del allele and two copies of the FREQ rs1054879 A allele were abstinent from smoking, compared to 29 38% abstinence rates for other smokers in the trial.

DRD2 drug nicotine 16123753 At the end of the treatment phase, a statistically significant (p=0.01) interaction between the DRD2 141C Ins/Del genotype and treatment indicated a more favorable response to bupropion among smokers homozygous for the Ins C allele compared to those carrying a Del C allele. DRD2 drug nicotine 16123753 These results suggest that bupropion may be the preferred pharmacologic treatment for smokers homozygous for the DRD2 141 Ins C allele, while NRT may be more beneficial for those who carry the Del C allele. DRD2 drug nicotine 15955630 The TaqIB polymorphism for the Dopamine D2 Receptor gene (DRD2) has been previously associated with smoking status, although with some contradictory results. DRD2 drug nicotine 15955630 We investigated whether genetic variants of MAO B intron 13 and DRD2 TaqIB polymorphism could be associated with smoking status among control subjects. DRD2 drug nicotine 15955630 Similarly, no association with smoking status was observed for the TaqIB polymorphism of DRD2 itself. DRD2 drug nicotine 15955630 However, among men, there was an interaction between MAO B intron 13 polymorphism and the DRD2 TaqIB polymorphisms, in which subjects carrying MAO B allele A and genotype B12 of DRD2 were 2.50 times (95% CI=1.05 5.95) more likely to be ever smokers than the pool of men carrying all other genotype combinations. DRD2 drug nicotine 15955630 These results demonstrate that particular combinations of genotypes for MAO B and DRD2 genes are associated with significantly higher risk for smoking behavior in men, but not in women.

DRD2 drug alcohol 12376935 We compared the TaqI A polymorphisms of the DRD2 gene in 120 French Caucasian alcohol dependent inpatients (62 males and 58 females) and 107 healthy ethnically matched controls (66 males and 41 females). DRD2 drug alcohol 12376935 We thus replicated the allelic association of the A1 allele of the DRD2 gene with alcohol dependence, but showed a male limited effect of this "vulnerability allele."

DRD2 addiction dependence 11918988 The A(1) allele of the D(2) dopamine receptor (DRD2) gene has been associated with alcohol dependence. DRD2 drug alcohol 11918988 The present study examines the association between DRD2 A(1)(+) (A(1)/A(1) and A(1)/A(2) genotypes) and A(1) (A(2)/A(2) genotype) allele status and key drinking parameters in alcohol dependent patients. DRD2 drug alcohol 11918988 In sum, alcohol dependent patients with the DRD2 A(1) allele compared to patients without this allele are characterized by greater severity of their disorder across a range of problem drinking indices. DRD2 addiction reward 11901357 The D2 and D4 dopamine receptors (DRD2 and DRD4) play major roles in the central effects of psychostimulants and in the reward system. DRD2 addiction dependence 11901357 Previous studies, although not all, have demonstrated associations between the DRD2 TaqI and the DRD4 exon III variable number tandem repeat (VNTR) polymorphisms and substance dependence. DRD2 addiction dependence 11901357 No significant difference was demonstrated for genotype or allele frequency when comparing MAP dependent and control cases for the DRD2 TaqI and the DRD4 gene exon III VNTR polymorphisms, suggesting that these two polymorphisms do not play major roles in MAP dependence for our sample of Chinese males.

DRD2 addiction dependence 11900611 Polymorphisms at the DRD2 locus in early onset alcohol dependence in the Indian population. DRD2 drug alcohol 11900611 Severe forms of the alcoholism phenotype have been associated with an increased frequency of the Taq A1 allele at the DRD2 locus. DRD2 drug alcohol 11807408 The results suggest that both the DRD2 promoter region and the DAT gene do not play a significant role in conferring vulnerability to alcoholism.

DRD2 drug alcohol 11553683 Here we used an adenoviral vector to deliver the dopamine D2 receptor (DRD2) gene into the nucleus accumbens of rats, previously trained to self administer alcohol, and to assess if DRD2 levels regulated alcohol preference and intake. DRD2 drug alcohol 11553683 We show that increases in DRD2 (52%) were associated with marked reductions in alcohol preference (43%), and alcohol intake (64%) of ethanol preferring rats, which recovered as the DRD2, returned to baseline levels. DRD2 drug alcohol 11553683 In addition, this DRD2 overexpression similarly produced significant reductions in ethanol non preferring rats, in both alcohol preference (16%) and alcohol intake (75%). DRD2 drug alcohol 11553683 This is the first evidence that overexpression of DRD2 reduces alcohol intake and suggests that high levels of DRD2 may be protective against alcohol abuse. DRD2 drug alcohol 11347517 More than 80% of alcoholics smoke cigarettes in the U.S.A. Other genetic methods such as linkage analysis, allele sharing methods, association studies and analysis of inbred, transgenic and gene knockout rodents, have partially agreed in showing that the 5HT 1B serotonin receptor and the DRD1, DRD2 and DRD4 dopamine receptors, as well as the dopamine transporter DAT, play an important role in behaviors related to alcoholism and substance abuse. DRD2 drug alcohol 11256581 The TaqIA D2 dopamine receptor (DRD2) minor (A1) allele was first associated with severe alcoholism a decade ago. DRD2 drug alcohol 11256581 However, a meta analysis of a large number of Caucasian alcoholics (both more severe and less severe) and controls (both assessed and unassessed for substance use disorders) revealed a significantly higher frequency (p < 10( 6)) and prevalence (p < 10( 8)) of the DRD2 A1 allele in the alcoholics. DRD2 drug alcohol 11256581 Further analysis showed that the more severe alcoholics had a 3 fold higher prevalence of the DRD2 A1 allele than the assessed controls (p < 10( 10)), whereas no difference was found between the less severe alcoholics and the unassessed controls. DRD2 drug alcohol 11256581 DRD2 exonic or promoter mutations have not yet been associated with alcoholism, although two intronic variants at the TaqIB and intron 6 sites, which are in linkage disequilibrium with the TaqIA site, were associated with this disorder.

DRD2 drug alcohol 11236830 Dopamine D2 receptor gene (DRD2) is associated with alcoholism with conduct disorder. DRD2 drug alcohol 11236830 This study examined whether there is evidence for an association between alcoholism with conduct disorder and alleles of the TaqI A and TaqI B polymorphisms, both individually and as haplotypes, at the dopamine D2 receptor gene (DRD2). DRD2 drug alcohol 11236830 Significant associations were observed between TaqI A and TaqI B at the DRD2 locus, tested individually and as haplotypes, and alcoholism with conduct disorder. DRD2 drug alcohol 11236830 Our results suggested that DRD2 might be associated with conduct disorder or a predisposition to both conduct disorder and alcoholism. DRD2 drug alcohol 11236830 However, this needs to be further investigated by examining the differences among conduct disorder with alcoholism, conduct disorder only, and controls for the TaqI A and B system at DRD2.

DRD2 drug alcohol 11054774 Using the transmission disequilibrium test, the present study examined linkage disequilibrium of alcohol and drug (opioid and/or cocaine) dependence with three DRD2 polymorphic systems: (a) TaqI A, (b) TaqI D, and (c) the functional 141CIns/Del promoter systems.

DRD2 addiction dependence 11054774 Together, these studies suggest that the conflicting findings from case control studies of the association between alleles of DRD2 and substance dependence may be attributable to population stratification in some samples. DRD2 drug alcohol 11054765 The frequency of the TaqI A(1) allele of the D(2) dopamine receptor (DRD2) gene was 19.0% in these patients compared with 4.6% in controls free of past and current alcohol and other drug abuse and free of family history of alcohol and other drug abuse (p = 0.009). DRD2 drug opioid 11054765 The results indicate that DRD2 variants are predictors of heroin use and subsequent methadone treatment outcome and suggest a pharmacogenetic approach to the treatment of opioid dependence.

DRD2 drug alcohol 11022024 Alcoholics with the dopamine receptor DRD2 A1 allele have lower platelet monoamine oxidase B activity than those with the A2 allele: a preliminary study. DRD2 drug alcohol 11022024 Low platelet monoamine oxidase B (MAO B) activity and the presence of the Taq1 A1 allele of the dopamine D2 receptor (DRD2) gene have independently been proposed as 'biological/genetic' markers for alcoholism. DRD2 drug alcohol 11022024 In the present study, the relationship between these two markers was investigated in a group of socially stable Caucasian middle aged men with a mean (+/ SD) daily ethanol consumption of 85 +/ 57 g. The platelet MAO B activity was significantly lower in individuals with the DRD2 A1 allele (n = 8), compared to those without it (n = 29). DRD2 drug alcohol 11022024 The finding suggests that alcoholics who are carriers of the DRD2 A1 allele may have lower platelet MAO B activity. DRD2 drug nicotine 20575861 The dopamine D2 receptor (DRD2) gene a genetic risk factor in heavy smoking? DRD2 drug nicotine 20575861 However, our results indicate an association between the DRD2 Fokl 1 allele and the onset and intensity of smoking. DRD2 drug alcohol 10898904 Allele and genotype frequencies of the TaqI A polymorphism of dopamine D2 receptor (DRD2) gene were compared in 115 alcohol dependent Brazilian males and 114 ethnically matched controls. DRD2 drug alcohol 10898904 Regression analyses were performed to test for an interactive effect between the DRD2 TaqI A1 allele and measures of stress and harm avoidance on severity of alcoholism and number of antisocial personality symptoms. DRD2 drug alcohol 10898904 A slightly positive association of DRD2 TaqI A1 genotypes with alcoholism was observed, by standard and molecular heterosis approaches. DRD2 addiction dependence 10898904 The DRD2 TaqI A1 allele showed significant interaction with stress and harm avoidance in predicting the severity of physiologic dependence, and with harm avoidance for the number of antisocial personality symptoms.

DRD2 drug alcohol 10881203 Since 1990, association studies have amassed strong evidence implicating the D(2) dopamine receptor (DRD2) gene in alcoholism. DRD2 drug alcohol 10881203 Specifically, the TaqI A minor (A1) allele of the DRD2 gene has been associated with alcoholism.

DRD2 drug nicotine 10710227 Family based study of the association of the dopamine D2 receptor gene (DRD2) with habitual smoking. DRD2 drug nicotine 10710227 A recent study showed an association between the dopamine D2 receptor gene (DRD2) and smoking. DRD2 drug nicotine 10710227 The purpose of this study was to determine if the familial transmission of smoking is linked to variation at the DRD2 locus in a genetically informative sample. DRD2 drug nicotine 10710227 There was no significant difference in the frequency between DRD2 alleles transmitted and not transmitted to habitual smokers. DRD2 drug alcohol 10710227 There also was no evidence for unequal transmission of DRD2 alleles for the phenotypes "ever smoker" or comorbid alcohol dependence and habitual smoking. DRD2 drug nicotine 10710227 There also was no evidence for unequal transmission of DRD2 alleles for the phenotypes "ever smoker" or comorbid alcohol dependence and habitual smoking. DRD2 addiction dependence 10710227 There also was no evidence for unequal transmission of DRD2 alleles for the phenotypes "ever smoker" or comorbid alcohol dependence and habitual smoking. DRD2 drug nicotine 10710227 This study does not support linkage of the DRD2 with smoking. DRD2 drug nicotine 10597409 This paper explores the relationship between the DRD2 gene polymorphism, P300, and smoking. DRD2 drug nicotine 10597409 Both smoking and DRD2 have significant reducing effects on P300 amplitude. DRD2 drug nicotine 10597409 The effect of smoking is apparent only in the presence of the A1 allele of the DRD2 locus. DRD2 drug nicotine 10597409 Both concordance for smoking and DRD2 genotype are significant predictors of sib pair similarity in P300 amplitude. DRD2 drug nicotine 10597409 Neurocognitive variation (P300) may moderate the association between DRD2 and smoking. DRD2 drug nicotine 10597409 Alternatively, DRD2 genotype may modulate the long term impact of nicotine on neurocognitive functioning.

DRD2 drug alcohol 10327432 Possible association between polymorphisms at the D2 dopamine receptor gene (DRD2) and alcohol dependence has been controversial since first proposed in 1990. DRD2 addiction dependence 10327432 Possible association between polymorphisms at the D2 dopamine receptor gene (DRD2) and alcohol dependence has been controversial since first proposed in 1990. DRD2 drug alcohol 10327432 To test the hypothesis of an association rigorously, we studied four DRD2 polymorphic systems in 160 EA alcohol dependent subjects and 136 screened EA control subjects. DRD2 drug alcohol 10327432 Thus, we replicated previous findings of no association between DRD2 alleles and alcohol dependence. DRD2 addiction dependence 10327432 Thus, we replicated previous findings of no association between DRD2 alleles and alcohol dependence.

DRD2 drug alcohol 10235293 No association between DRD2 locus and alcoholism after controlling the ADH and ALDH genotypes in Chinese Han population. DRD2 drug alcohol 10235293 Recent studies on the genetics of alcoholism have examined the association between alcoholism and the dopamine D2 receptor locus (DRD2); our study of Chinese Han gave negative results (Lu et al., 1996). DRD2 drug alcohol 10235293 Therefore, association studies of alcoholism in Chinese Han might be more sensitive if controlled for the genotypes of ADH2,ADH3, and ALDH2, when other loci, such as DRD2, are examined. DRD2 drug alcohol 10235293 This study employs such controls to evaluate the evidence for an association between alcoholism and TaqI A and TaqI B genotypes and haplotypes at DRD2 in the Chinese Han population. DRD2 drug alcohol 10235293 Significant linkage disequilibrium was observed between the TaqI A and TaqI B sites at the DRD2 locus, as previously seen in smaller samples, but no significant association was observed between these genetic variants at the DRD2 locus and alcoholism in Chinese Han. DRD2 drug alcohol 10235293 Several different stratifications by ADH and ALDH2 genotypes were examined; no genotypes or haplotypes at DRD2 differ between alcoholics and nonalcoholics except for a small number of nominally significant p values which do not constitute significant results given the many tests done, some of which are not independent of one another due to linkage disequilibrium. DRD2 drug alcohol 10235293 After stratification by the relevant genotypes of ADH2, ADH3, and ALDH2 no significant association exists between the genetic variants at the DRD2 locus and alcoholism in the Chinese Han population.

DRD2 addiction reward 10220438 Neurotransmission mediated by DRD2 is known to have a key role in the control of movement and also has been implicated in reward and reinforcement mechanisms and psychiatric disorders. DRD2 drug alcohol 20575787 The dopaminergic system has been implicated in alcoholism, but most of the past investigations concentrated on the dopamine D2 receptor (DRD2), with conflicting results.

DRD2 drug cocaine 10023512 In an attempt to replicate the reported association between DRD2 alleles, substance dependence, and severity of substance dependence, we studied allele frequencies for three polymorphic DRD2 systems (TaqI "A," "B," and "D") in 96 EA and 77 African American (AA) cocaine dependent subjects, and 87 EA and 45 AA control subjects.

DRD2 drug nicotine 10022750 Furthermore, neither measure of dependence was affected by possession of the A1 allele; the only difference between DRD2*A1 bearing and DRD2*A2 homozygous individuals in terms of smoking motives was found in the scores for indulgence; the former having a moderately reduced score (by 17%, p < 0.05). DRD2 addiction dependence 10022750 Furthermore, neither measure of dependence was affected by possession of the A1 allele; the only difference between DRD2*A1 bearing and DRD2*A2 homozygous individuals in terms of smoking motives was found in the scores for indulgence; the former having a moderately reduced score (by 17%, p < 0.05). DRD2 drug nicotine 10022750 This may be caused by the locus being unrelated to impulsive/addictive/compulsive behaviour, the polymorphism being in linkage disequilibrium with another distinct locus or, alternatively, smoking may represent a behaviour that is not directly comparable to impulsive/addictive/compulsive behaviours previously associated with the DRD2*A1 allele.

DRD2 drug nicotine 9925041 As a means of investigating the risk of smoking associated with genetic polymorphisms in the dopamine transporter (SLC6A3) and the D2 dopamine receptor (DRD2) genes, a case control study of 289 smokers and 233 nonsmoking controls and a case series analysis of smokers were conducted. DRD2 drug nicotine 9925041 A significant effect for SLC6A3 and a significant gene gene interaction were found in a logistic regression model, indicating that individuals with SLC6A3 9 genotypes were significantly less likely to be smokers, especially if they also had DRD2 A2 genotypes.

DRD2 drug alcohol 9650635 Genotyping of Ser311Cys, the DRD2 intron 2 STR, and the Taq1A marker in 459 subjects, including 373 sib pairs and 15 Cys311/Cys311 homozygous individuals, revealed no association to alcoholism, substance use disorders, or schizophrenia. DRD2 drug alcohol 9650635 The implication is that a DRD2 variant that dramatically impairs receptor function was not sufficient to significantly alter alcoholism vulnerability in a relatively large and also genetically and environmentally homogeneous sample. DRD2 drug alcohol 9603615 The relationship of various dimensions of temperament, measured by the Tridimensional Personality Questionnaire (TPQ), to polymorphisms of the D2 dopamine receptor (DRD2) and D4 dopamine receptor (DRD4) genes was determined in 119 healthy Caucasian boys who had not yet begun to consume alcohol and other drugs of abuse. DRD2 addiction relapse 9603615 Total Novelty Seeking score of the TPQ was significantly higher in boys having, in common, all three minor (A1, B1, and Intron 6 1) alleles of the DRD2 compared to boys without any of these alleles. DRD2 addiction relapse 9603615 However, the greatest difference in Novelty Seeking score was found when boys having all three minor DRD2 alleles and the DRD4 7R allele were contrasted to those without any of these alleles. DRD2 addiction dependence 9603615 Whereas subjects having all three minor DRD2 alleles had a significantly higher Reward Dependence 2 (Persistence) score than subjects without any of these alleles, no significant difference in this personality score was found between subjects with and without the DRD4 7R allele. DRD2 addiction reward 9603615 Whereas subjects having all three minor DRD2 alleles had a significantly higher Reward Dependence 2 (Persistence) score than subjects without any of these alleles, no significant difference in this personality score was found between subjects with and without the DRD4 7R allele. DRD2 addiction relapse 9603615 In conclusion, DRD2 and DRD4 polymorphisms individually associate with Novelty Seeking behavior. DRD2 drug alcohol 9581660 A family based analysis of the association of the dopamine D2 receptor (DRD2) with alcoholism. DRD2 drug alcohol 9581660 The possible association of the DRD2 locus, and in particular the Taql A1 allele, with alcoholism remains controversial, in part because of differences in allele frequencies among populations. DRD2 drug alcohol 9581660 To avoid problems associated with differences in allele frequencies in different populations, we tested whether the DRD2 locus is associated with alcohol dependence in a large family based sample. DRD2 addiction dependence 9581660 To avoid problems associated with differences in allele frequencies in different populations, we tested whether the DRD2 locus is associated with alcohol dependence in a large family based sample. DRD2 drug alcohol 9581660 Neither the transmission/disequilibrium test nor the Affected Family Based Controls test provide any evidence of linkage or association between the DRD2 locus and alcohol dependence. DRD2 addiction dependence 9581660 Neither the transmission/disequilibrium test nor the Affected Family Based Controls test provide any evidence of linkage or association between the DRD2 locus and alcohol dependence. DRD2 drug alcohol 9295055 Influence of the dopamine D2 receptor (DRD2) genotype on neuroadaptive effects of alcohol and the clinical outcome of alcoholism. DRD2 drug alcohol 9295055 The present study was performed to test the hypotheses that allelic variants at the human dopamine D2 receptor gene locus (DRD2) confer susceptibility to alcoholism or are associated with clinical subtypes of alcoholism. DRD2 drug alcohol 9295055 No significant association of the DRD2 genotype or allele frequencies with alcoholism was found in an association study including 283 alcoholics and 146 non alcoholic controls. DRD2 drug alcohol 9295055 Regression analysis revealed the DRD2 E8 genotype as the only significant factor determining withdrawal severity in female alcoholics. DRD2 addiction withdrawal 9295055 Regression analysis revealed the DRD2 E8 genotype as the only significant factor determining withdrawal severity in female alcoholics. DRD2 drug alcohol 9295055 The findings suggest an influence of the DRD2 genotype on the neuropharmacological effects of chronic alcohol exposure and the clinical course of alcoholism. DRD2 drug alcohol 9259374 Linkage and association of a functional DRD2 variant [Ser311Cys] and DRD2 markers to alcoholism, substance abuse and schizophrenia in Southwestern American Indians. DRD2 drug alcohol 9259374 Furthermore, sib pair analysis incorporating information across all three sib pair categories: concordant affected, discordant and concordant unaffected revealed no effect of DRD2 genotype or haplotype on alcoholism or substance use disorder. DRD2 drug alcohol 9129720 We examined the allelic association between the dopamine D2 receptor (DRD2) gene and alcoholism in 100 biologically unrelated Japanese alcoholics and 93 unrelated controls. DRD2 drug alcohol 9129720 The results indicate that the DRD2 gene is associated with susceptibility to early onset alcoholism, and that each additional A1 allele shifts onset of alcoholism to an earlier age. DRD2 drug alcohol 9129716 Molecular genetic studies have found an association of the D2 dopamine receptor (DRD2) A1 allele with alcoholism and drug abuse. DRD2 drug alcohol 9129710 Previous studies examining the putative association between DRD2 TaqI A1 and alcoholism have produced conflicting results. DRD2 drug alcohol 9129710 To address these issues, we compared the allelic frequency of two polymorphisms of DRD2, TaqI A and NcoI, among severe alcoholics and their ethnically matched nonalcoholic controls within four major aboriginal groups and Han (Chinese) in Taiwan. DRD2 drug alcohol 9129710 Severity in medical complications of alcohol dependence with withdrawal symptoms was not associated with higher prevalence of DRD2 TaqI A1 or NcoI N1 alleles. DRD2 addiction dependence 9129710 Severity in medical complications of alcohol dependence with withdrawal symptoms was not associated with higher prevalence of DRD2 TaqI A1 or NcoI N1 alleles. DRD2 addiction withdrawal 9129710 Severity in medical complications of alcohol dependence with withdrawal symptoms was not associated with higher prevalence of DRD2 TaqI A1 or NcoI N1 alleles. DRD2 drug alcohol 9129710 The absence of an association between DRD2 and alcoholism among the three aboriginal groups suggests either a higher rate of phenocopies among aboriginal alcoholics or genetic heterogeneity in the susceptibility to alcoholism. DRD2 drug alcohol 9034534 The dopaminergic system has been implicated in alcoholism but studies at the dopamine D2 receptor gene (DRD2), one of the five dopamine receptors, have not given a consistent picture of an association with alcoholism. DRD2 drug nicotine 9154217 In the TS group and smokers there was a significant additive effect of the DRD1 and DRD2 genes. DRD2 addiction addiction 9154217 These results support a role for genetic variants of the DRD1 gene in some addictive behaviors, and an interaction of genetic variants at the DRD1 and DRD2 genes. DRD2 addiction addiction 8873216 These preliminary data suggest that the presence of the DRD2 A1 allele confirms increased risk not only for obesity, but also for other related addictive behaviours (previously referred to as the Reward Deficiency Syndrome) and that a BMI over 25 by itself (without characterization of macroselection or comorbid substance use disorders) is not a sufficient criterion for association with the DRD2 A1 allele.

DRD2 drug alcohol 8807661 The Taq A1 variant of the human DRD2 gene has been associated with drug addiction, some forms of severe alcoholism, and other impulsive, addictive behaviours. DRD2 addiction addiction 8807661 The Taq A1 variant of the human DRD2 gene has been associated with drug addiction, some forms of severe alcoholism, and other impulsive, addictive behaviours. DRD2 addiction addiction 8807661 These results suggest that genetic variants at the DRD2 gene play a role in pathological gambling, and support the concept that variants of this gene are a risk factor for impulsive and addictive behaviours. DRD2 drug nicotine 8845863 The dopamine D2 receptor (DRD2) gene: a genetic risk factor in smoking. DRD2 drug alcohol 8845863 Of a group of 312 non Hispanic Caucasians who smoked at least one pack per day, had unsuccessfully attempted to stop smoking, and were free of alcohol or other drug dependence, 48.7% carried the A1 allele of the DRD2 gene. DRD2 drug nicotine 8845863 Of a group of 312 non Hispanic Caucasians who smoked at least one pack per day, had unsuccessfully attempted to stop smoking, and were free of alcohol or other drug dependence, 48.7% carried the A1 allele of the DRD2 gene. DRD2 addiction dependence 8845863 Of a group of 312 non Hispanic Caucasians who smoked at least one pack per day, had unsuccessfully attempted to stop smoking, and were free of alcohol or other drug dependence, 48.7% carried the A1 allele of the DRD2 gene. DRD2 drug nicotine 8845863 These results suggest the DRD2 gene is one of a multifactorial set of risk factors associated with smoking. DRD2 drug alcohol 12893451 In animal genetic models of alcoholism, reduced dopamine levels and D2 dopamine receptor (DRD2) numbers have been found in the brains of alcohol preferring animals. DRD2 drug alcohol 12893451 Moreover, quantitative trait loci studies in animals suggest the DRD2 gene and the region proximate to this locus is a chromosomal "hot spot" for alcohol related behaviors. DRD2 drug alcohol 12893451 Molecular genetic studies in humans have identified an association of the Al allele of the DRD2 gene with alcoholism. DRD2 drug alcohol 12893451 Further, treatment of alcoholics with a dopamine receptor agonist showed more salutary effects on alcoholics who carry than those who do not carry the DRD2 A1 allele. DRD2 addiction reward 12893451 The emerging evidence suggests that the DRD2 is a reinforcement or reward gene. DRD2 drug alcohol 8907305 The human dopamine 2 receptor gene (DRD2) is an important candidate gene for drug addiction and alcoholism. DRD2 addiction addiction 8907305 The human dopamine 2 receptor gene (DRD2) is an important candidate gene for drug addiction and alcoholism. DRD2 addiction addiction 8907305 So far, no mutations within the coding region of DRD2 have been found to be associated with addiction disorders. DRD2 drug alcohol 8907305 The allele specific PCR allowed the reliable testing of 95 healthy control individuals and 270 alcoholics for analyzing a possible genetic association of this newly characterized polymorphic DRD2 marker with alcoholism in an ethnically and clinically homogenous group of patients. DRD2 drug alcohol 8825889 Numerous studies on the involvement of dopamine receptors in the genetics of alcoholism focused on associations between a polymorphism of the D2 dopamine receptor (DRD2) gene and alcohol dependence. DRD2 addiction dependence 8825889 Numerous studies on the involvement of dopamine receptors in the genetics of alcoholism focused on associations between a polymorphism of the D2 dopamine receptor (DRD2) gene and alcohol dependence. DRD2 drug alcohol 8825889 No difference in the DRD3 gene polymorphism emerged between controls and alcoholic patients, regardless of their origin, inclusion criteria, or presence or absence of the DRD2 TaqI A1 allele. DRD2 drug alcohol 7485259 To address the controversy surrounding DRD2 and alcoholism, we performed linkage and association studies utilizing alcoholic men from high density families largely uncontaminated by other psychopathology and female alcoholics for whom secondary drug dependence (averaging 10 years later onset) was a prominent feature.

DRD2 drug alcohol 7550364 While other neurotransmitters have also been implicated, to date the only molecular genetic defect which has been found to associate with alcoholism, drug dependency, obesity, smoking, pathological gambling, attention deficit hyperactivity disorder (ADHD), Tourette syndrome, as well as other related compulsive behaviours, are the variants of the dopamine D2 receptor gene (DRD2).

DRD2 addiction addiction 7550364 In this review of the available data on the subject, we report a number of independent meta analyses that confirm an association of DRD2 polymorphisms and impulsive additive compulsive behaviour (IACB), which we have termed "Reward Deficiency Syndrome". DRD2 addiction reward 7550364 In this review of the available data on the subject, we report a number of independent meta analyses that confirm an association of DRD2 polymorphisms and impulsive additive compulsive behaviour (IACB), which we have termed "Reward Deficiency Syndrome". DRD2 drug alcohol 7550364 While we agree that Meta analyses of all exant studies support an association of variants of DRD2 and IACB, correct negative findings with alcoholism may be due to differences in assessing controls and inclusion/exclusion criteria for selection of diseased probands. DRD2 drug alcohol 7585063 An important role of the mesolimbic dopamine system has been suggested in the reinforcing effects of alcohol and recent molecular genetic studies are implicating the gene for the D2 dopamine receptor (DRD2) in alcoholism. DRD2 addiction reward 7585063 An important role of the mesolimbic dopamine system has been suggested in the reinforcing effects of alcohol and recent molecular genetic studies are implicating the gene for the D2 dopamine receptor (DRD2) in alcoholism. DRD2 drug alcohol 7585063 In a double blind study, bromocriptine, a DRD2 agonist, or placebo was administered to alcoholics with either the A1 (A1/A1 and A1/A2 genotypes) or only the A2 (A2/A2 genotype) allele of the DRD2 gene. DRD2 drug alcohol 8555738 The suggested association between the TaqI A1 allele of the dopamine D2 receptor (DRD2) gene with alcoholism was studied comparing the genotypes of 38 controls and 38 ethnic matched alcoholics, drawn from the Mexican population. DRD2 drug alcohol 7704037 In the present investigation, 155 Caucasian male and female diagnosed neuropsychiatrically ill patients with and without comorbid drug and alcohol abuse/dependence were genotyped for the presence or absence of the A1 allele of the D2 dopamine receptor gene (DRD2). DRD2 addiction dependence 7704037 In the present investigation, 155 Caucasian male and female diagnosed neuropsychiatrically ill patients with and without comorbid drug and alcohol abuse/dependence were genotyped for the presence or absence of the A1 allele of the D2 dopamine receptor gene (DRD2). DRD2 drug alcohol 7695792 The prevalence of TaqI A alleles of the D2 dopamine receptor (DRD2) gene was examined in two subgroups of medically ill nonalcoholics (more prevalent and less prevalent substance users, MPSU and LPSU, respectively) and in two subgroups of medically ill alcoholics (more severe and less severe alcoholics, MSA and LSA, respectively). DRD2 drug alcohol 7695792 In conclusion, the severity of alcohol dependence in alcoholics and of substance use behaviors in controls are important variables in DRD2 allelic association. DRD2 addiction dependence 7695792 In conclusion, the severity of alcohol dependence in alcoholics and of substance use behaviors in controls are important variables in DRD2 allelic association. DRD2 drug alcohol 7695792 The present report and converging lines of evidence suggest that the DRD2 locus could represent a prominent gene risk factor for susceptibility to severe alcoholism. DRD2 drug alcohol 8072432 There is now growing evidence that the less prevalent allele (A1) of the D2 dopamine receptor (DRD2) gene is strongly associated with severe alcoholism. DRD2 addiction addiction 8033754 To examine the possible role of genetic variants of the dopamine D2 (DRD2) gene in susceptibility to drug abuse we determined the prevalence of the TaqI A1 variant of the DRD2 gene in 200 white patients hospitalized in the Addiction Treatment Unit of a Veterans Administration Hospital. DRD2 drug alcohol 8974314 The A1 (minor) allele of the D2 dopamine receptor (DRD2) gene has been shown to be associated with alcoholism, particularly the severe form of this disorder. DRD2 addiction reward 8974314 Moreover, reduced dopaminergic function has been found in subjects carrying the DRD2 A1 allele, suggesting that the DRD2 may be a reinforcement or reward gene. DRD2 drug alcohol 8974314 Analysis of the available data suggests that the DRD2 variants represent one of the most prominent single gene determinants of susceptibility to severe alcoholism and other substance use disorders. DRD2 drug cocaine 8261891 The objective of the present study was to examine allelic prevalence of the D2 dopamine receptor (DRD2) gene in male cocaine dependent (CD) Caucasian (non Hispanic) subjects and to determine the relationship of DRD2 alleles to family history and selected behavioral measures. DRD2 drug cocaine 8261891 The data showing a strong association of the minor alleles (A1 and B1) of the DRD2 with cocaine dependence suggest that a gene, located on the q22 q23 region of chromosome 11, confers susceptibility to this drug disorder. DRD2 addiction dependence 8261891 The data showing a strong association of the minor alleles (A1 and B1) of the DRD2 with cocaine dependence suggest that a gene, located on the q22 q23 region of chromosome 11, confers susceptibility to this drug disorder. DRD2 drug alcohol 8488955 DRD2 dopamine receptor genotype, linkage disequilibrium, and alcoholism in American Indians and other populations. DRD2 drug alcohol 8488955 We defined interpopulation differences in the frequency of the dopamine D2 receptor DRD2/Taq1 A1 allele, which has previously been associated with alcoholism. DRD2 drug alcohol 8488955 Legitimate association of the DRD2/Taq1 allele to alcoholism would presumably require it to be in linkage disequilibrium (nonrandom association) with a functional mutation at DRD2 or elsewhere. DRD2 drug alcohol 1347705 Blum et al (1990) have recently examined a restriction fragment length polymorphism (RFLP) detected by TaqI RFLP to the dopamine D2 receptor gene (DRD2) in deceased alcoholics and nonalcoholics, and reported an association between alcoholism and the A1 allele. DRD2 drug alcohol 1347705 We have examined the DRD2 TaqI RFLP in 47 living Caucasian males with severe alcoholism. DRD2 drug alcohol 1832467 No association between an allele at the D2 dopamine receptor gene (DRD2) and alcoholism. DRD2 drug alcohol 1832467 We attempted to replicate a positive allelic association between the A1 allele of DRD2 (the D2 dopamine receptor locus) and alcoholism that has been reported. DRD2 drug alcohol 1832467 We compared allele frequencies at the previously described Taq I restriction fragment length polymorphism system of DRD2 in alcoholics and random population controls. DRD2 drug alcohol 1832467 There were no significant differences in allele frequencies at the DRD2 locus between alcoholics and controls. DRD2 drug alcohol 1832467 We conclude that our data do not support an allelic association between the A1 allele at DRD2 and alcoholism. DRD2 drug alcohol 1832466 The A1 allele of the Taq I polymorphism of the dopamine D2 receptor (DRD2) gene has been earlier reported to occur in 69% of alcoholics, compared with 20% of controls. DRD2 drug alcohol 1832466 Other research has reported no significant difference in the prevalence of the A1 allele in alcoholics vs controls and no evidence that the DRD2 gene was linked to alcoholism. SLC6A4 drug cocaine 32721055 Previous research showed that inherited serotonin transporter (SERT) down regulation increases the motor response to cocaine, as well as moderate (as measured during daily 1 hr self administration sessions) and compulsive (as measured during daily 6 hr self administration sessions) intake of this psychostimulant.

SLC6A4 drug amphetamine 32721055 In serotonin transporter knockout (SERT / ) and wild type control (SERT+/+) rats we assessed the locomotor response to acute amphetamine (AMPH) and intravenous AMPH self administration under short access (ShA: 1 hr daily sessions) and long access (LgA: 6 hr daily sessions) conditions. SLC6A4 drug amphetamine 32721055 We found that SERT / animals displayed an increased AMPH induced locomotor response and increased AMPH self administration under LgA, but not ShA conditions. SLC6A4 drug amphetamine 32721055 We demonstrate that SERT gene deletion increases the psychomotor and reinforcing effects of AMPH, and that the latter is potentially mediated, at least in part, by homeostatic changes in the glutamatergic synapse of the nucleus accumbens shell and/or core.

SLC6A4 drug cocaine 30817127 In particular, a significant body of work points to altered serotonin (5 HT) signaling as one such component, not surprising given that, relative to DAT, cocaine acts as potently to block the 5 HT transporter (SERT) as to block DAT, and thereby elevates extracellular 5 HT levels throughout the brain when reward eliciting DA elevations occur.

SLC6A4 drug cocaine 30817127 To elucidate the contribution of SERT antagonism to the actions of cocaine, we engineered a mouse model that significantly reduces cocaine potency at SERT without disrupting the expression or function of SERT in vivo. SLC6A4 drug cocaine 30817127 In this short Perspective, we review the rationale for development of the SERT Met172 model, the studies that document the pharmacological impact of the Ile172Met substitution in vitro and in vivo, and our findings with the model that demonstrate serotonergic contributions to the genetic, physiological, and behavioral actions of cocaine. SLC6A4 drug nicotine 30815604 Additionally, this study examined whether the S allele of the serotonin transporter gene linked polymorphic region (5 HTTLPR) is associated with the BDNF Val66Met polymorphism on smoking phenotypes. SLC6A4 drug nicotine 30815604 Moreover, the 5 HTTLPR polymorphism was associated with the age of smoking initiation in current smokers carrying the BDNF Met allele, in both the whole study sample (P = 0.041) and the male subgroup (P = 0.041). SLC6A4 drug nicotine 30815604 On the other hand, no association was observed between the BDNF Val66Met polymorphism, either alone or in combination with the 5 HTTLPR polymorphism, and the age of smoking cessation. SLC6A4 drug nicotine 30815604 This pilot study provides preliminary findings regarding the influence of BDNF Val66Met on smoking phenotypes and the interacting effect of 5 HTTLPR on the association between BDNF Val66Met and smoking phenotypes in Japanese participants. SLC6A4 drug cocaine 30748070 Here, we tested this idea by using ultrahigh resolution structural magnetic resonance imaging (MRI) on postmortem tissue of 5 HTT / and wild type (5 HTT+/+) rats with a history of long access to cocaine or sucrose (control) self administration. SLC6A4 drug cocaine 30748070 We found that 5 HTT / rats, compared with wild type control animals, self administered more cocaine, but not sucrose, under long access conditions. SLC6A4 drug cocaine 30748070 Ultrahigh resolution structural MRI subsequently revealed that, independent of sucrose or cocaine self administration, 5 HTT / rats had a smaller amygdala.

SLC6A4 drug amphetamine 30578419 Given that amphetamine and methylphenidate, unlike cocaine, lack high affinity interactions with the serotonin (5 HT) transporter (SERT), we hypothesized that the lack of cocaine induced hyperlocomotion in DAT Val559 mice arises from SERT blockade and augmented 5 HT signaling relative to cocaine actions on wildtype animals. SLC6A4 drug cocaine 30578419 Given that amphetamine and methylphenidate, unlike cocaine, lack high affinity interactions with the serotonin (5 HT) transporter (SERT), we hypothesized that the lack of cocaine induced hyperlocomotion in DAT Val559 mice arises from SERT blockade and augmented 5 HT signaling relative to cocaine actions on wildtype animals.

SLC6A4 addiction reward 30305739 To this end, we tested the hypothesis that reinforcing effectiveness of cathinone stimulants is positively correlated with their selectivity for DAT relative to SERT. SLC6A4 drug cocaine 30305739 Uptake inhibition assays in rat brain synaptosomes were used to directly compare the potency of MDPV, MDPBP, MDPPP, α PVP, α PPP, and cocaine at DAT, NET, and SERT, whereas intravenous self administration in rats was used to quantify relative reinforcing effectiveness of the drugs using progressive ratio (PR) and behavioral economic procedures.

SLC6A4 drug cocaine 24950119 Although our data are consistent with cocaine acting through enhanced 5 HT signaling, the nonselective actions of cocaine as an antagonist of monoamine transporters raises the question of whether inhibition of the 5 HT transporter (SERT) is key to its circadian effects. SLC6A4 drug cocaine 24950119 Here we investigate this issue using transgenic mice expressing a SERT that exhibits normal 5 HT recognition and transport but significantly reduced cocaine potency (SERT Met172). SLC6A4 drug cocaine 24950119 However, (1) cocaine administration does not induce phase advances when administered in vivo or in vitro in SERT Met172 mice; (2) cocaine does not block photic or glutamate induced phase shifts in SERT Met172 mice; and (3) cocaine does not induce long term changes in free running period in SERT Met172 mice. SLC6A4 drug cocaine 24950119 We conclude that SERT antagonism is required for the phase shifting of the SCN circadian clock induced by cocaine.

SLC6A4 drug alcohol 24408213 We aimed at assessing whether the association between alcohol use and 5 HTTLPR genotype is subject to cohort effects as birth cohorts may be raised in significantly different environments. SLC6A4 drug alcohol 24408213 In males, there was no significant cohort × genotype interaction, but the 5 HTTLPR genotype was associated with alcohol use, the s/s subjects reporting the highest consumption. SLC6A4 drug alcohol 24408213 The 5 HTTLPR genotype is associated with alcohol consumption in general population, but the effect depends on gender and birth cohort.

SLC6A4 drug alcohol 23927813 To examine the relationship between SERT genotype and motivation for alcohol, we compared ethanol self administration in mice with zero (knockout, KO), one (HET) or two copies (WT) of the SERT gene. SLC6A4 drug alcohol 23897038 The authors previously reported that the 5' HTTLPR LL and rs1042173 TT (SLC6A4 LL/TT) genotypes in the serotonin transporter gene predicted a significant reduction in the severity of alcohol consumption among alcoholics receiving the 5 HT3 antagonist ondansetron. SLC6A4 drug amphetamine 23798435 We tested the effects of the verified scarcity of PIP2 on amphetamine triggered SERT functions in human cells.

SLC6A4 drug amphetamine 22647900 METH self administration per se had no persistent effect on hippocampal 5HT content or SERT function. SLC6A4 drug alcohol 22587755 A polymorphism in the serotonin transporter gene SLC6A4 promoter region appears related to differential treatment response to sertraline depending on the subject's age of onset of alcoholism. SLC6A4 drug alcohol 22557982 The current study investigated the effects of chronic ethanol self administration on hippocampal SERT in a layer and field specific manner using a monkey model of human alcohol consumption. SLC6A4 drug alcohol 22557982 [(3)H]Citalopram was used to measure hippocampal SERT density in male cynomolgus macaques that voluntarily self administered ethanol for 18 months. SLC6A4 drug alcohol 22557982 SERT density was not correlated with measures of ethanol consumption or blood ethanol concentrations, suggesting the possibility that a threshold level of consumption had been met. SLC6A4 drug alcohol 22557982 The lower hippocampal SERT density observed suggests that chronic ethanol consumption is associated with altered serotonergic modulation of hippocampal neurotransmission.

SLC6A4 addiction withdrawal 22451652 Ibogaine, a hallucinogenic alkaloid proposed as a treatment for opiate withdrawal, has been shown to inhibit serotonin transporter (SERT) noncompetitively, in contrast to all other known inhibitors, which are competitive with substrate. SLC6A4 drug psychedelics 22451652 Ibogaine binding to SERT increases accessibility in the permeation pathway connecting the substrate binding site with the cytoplasm. SLC6A4 drug psychedelics 22451652 Because of the structural similarity between ibogaine and serotonin, it had been suggested that ibogaine binds to the substrate site of SERT. SLC6A4 drug psychedelics 22451652 Ibogaine noncompetitively inhibited transport by both SERT and the homologous dopamine transporter (DAT). SLC6A4 drug psychedelics 22451652 When present on the cell exterior, ibogaine inhibited SERT substrate induced currents, but not when it was introduced into the cytoplasm through the patch electrode. SLC6A4 drug psychedelics 22451652 The kinetics of inhibitor binding and dissociation, as determined by their effect on SERT currents, indicated that ibogaine does not inhibit by forming a long lived complex with SERT, but rather binds directly to the transporter in an inward open conformation.

SLC6A4 drug cocaine 20122955 To address the role of serotonin (5 HT) in cocaine induced aversions, the present experiments used the cross drug preexposure design in which the effects of exposure to fluoxetine, a selective 5 HT reuptake inhibitor (SSRI) with 5 HT transporter (SERT) inhibitory properties, were examined on aversions induced by cocaine (a nonselective monoamine transport inhibitor) and the effects of cocaine preexposure were examined on fluoxetine induced aversions. SLC6A4 drug nicotine 20060656 5 HTTLPR polymorphism of the 5 HT transporter gene and 759C/T (rs3813929) and 697G/C (rs518147) polymorphisms of the 5 HT(2C) receptor gene were analyzed in 172 smoking initiators and 254 non initiators, using PCR RFLP method.

SLC6A4 drug amphetamine 21423453 An earlier onset of methamphetamine use leads to greater damage to the terminal ends of serotonin neurons, more reduction in serotonin transporter (5 HTT) density, and an increased propensity toward further methamphetamine use. SLC6A4 drug amphetamine 21423453 Because the 5 HTT linked polymorphic region (5' HTTLPR) within the promoter region of the 5 HTT gene leads to differential expression of the 5 HTT, we examined, for the first time, whether there is a differential association between the long (L) and short (S) alleles of the 5' HTTLPR and the age of first methamphetamine use (AMU). SLC6A4 drug psychedelics 20002520 Experiment 1 investigated MDMA induced changes in levels of the serotonin transporter (SERT) and the vesicular monoamine transporter 2 (VMAT 2) in the hippocampus, a region with sparse dopaminergic innervation, after lesioning noradrenergic input with N (2 chloroethyl) N ethyl 2 bromobenzylamine (DSP 4). SLC6A4 drug psychedelics 20002520 Two weeks following the binge treatment, the DSP 4/MDMA group unexpectedly showed little change in hippocampal VMAT 2 protein expression compared with DSP 4/Saline controls, despite large reductions in SERT levels in all regions examined in the MDMA treated animals.

SLC6A4 drug psychedelics 19878141 5 HTTLPR polymorphism was associated with lifetime of primary mood disorders in ecstasy group (P = 0.018). SLC6A4 drug psychedelics 19878141 In the ecstasy users, 5 HTTLPR polymorphism may result in a high vulnerability to primary mood disorders. SLC6A4 drug psychedelics 19824774 MDMA pretreatment was hypothesized to enhance the effects of CUS leading to enhanced 5 HT transporter (SERT) depletion in the hippocampus and increased anxiety and cognitive impairment. SLC6A4 drug psychedelics 19824774 In contrast, MDMA pretreatment led to CUS induced learning impairment in the Morris water maze but not an enhanced depletion of hippocampal SERT protein. SLC6A4 drug psychedelics 19824774 These results show that prior exposure to MDMA leads to stress induced impairments in learning behavior that is not otherwise observed with stress alone and appear unrelated to an enhanced depletion of SERT.

SLC6A4 drug cocaine 19482066 Surprisingly, locomotor responses in the cocaine paired subjects diminished over the five conditioning sessions in SERT KO mice, while locomotor responses increased in DAT KO mice, despite the fact that they did not demonstrate any initial locomotor responses to cocaine. SLC6A4 drug alcohol 19426172 These results not only provide support for the hypothesis that alcoholics who are L carriers have greater alcohol craving and possibly greater propensity for drinking but also propose that there is an important 5 HTT gene by environment interaction that alters cue craving response for alcohol.

SLC6A4 drug nicotine 19396697 As one of the candidate genes in relation to smoking, the serotonin transporter gene (5 HTTLPR) has been suggested, however with conflicting results. SLC6A4 drug nicotine 19396697 The objective of the present study was to investigate the interaction between a variation in the 5 HTTLPR and family environment in relation to smoking habits, nicotine dependence, and nicotine and cotinine levels in hair samples. SLC6A4 addiction dependence 19396697 The objective of the present study was to investigate the interaction between a variation in the 5 HTTLPR and family environment in relation to smoking habits, nicotine dependence, and nicotine and cotinine levels in hair samples. SLC6A4 drug nicotine 19396697 A random Swedish adolescent population sample (n = 785), from which 200 individuals were stratified regarding behaviour, was genotyped for 5 HTTLPR and assessed with semi structured interviews, a questionnaire, and hair analyses of nicotine and cotinine. SLC6A4 drug nicotine 19396697 The 5 HTTLPR gene interacted with a poor family environment to predict smoking habits, as well as nicotine and cotinine levels. SLC6A4 drug nicotine 19396697 The risk of being a smoker was increased 13 times for an individual with a combination of the 5 HTTLPR LS genotype and a poor family environment in comparison with the Homozygous Long Long (LL) genotype and a good family environment.

SLC6A4 drug alcohol 19331786 [Association of the functional serotonin transporter promoter polymorphism (5 HTTLPR) with externalizing and internalizing aggressivity and alcohol abuse]. SLC6A4 drug alcohol 19331786 The pathogenesis of alcoholism and anti social behaviour has been connected to serotonergic system dysfunction, given support to examine the association with 44 basepair insertion/deletion polymorphism of serotonin gene transporter (5 HTT). SLC6A4 drug alcohol 19331786 Regarding 5 HTTLPR polymorphism prevalence in alcoholic population, 30.7% were homozygotic to l allele, 19.8% were homozygotic to s allele and 49.5% were heterozygotic l/s. SLC6A4 drug alcohol 19331786 Alcoholic patients carrying the l allele from 5 HTTLPR genotype showed significant lower scores of aggressivity during acute alcohol consumption, and alcoholic patients carrying the s allele showed significant higher scores of aggressivity (during acute alcohol consumption and abstinence), however, the results were not significant. SLC6A4 drug alcohol 19331786 The results demonstrate an association between 5 HTTLPR polymorphism and the auto and heteroaggressive behaviour in alcohol dependent population, particularly when aggressivity appears under acute alcohol consumption.

SLC6A4 drug nicotine 18691405 Lack of association between serotonin transporter gene polymorphism 5 HTTLPR and smoking among Polish population: a case control study. SLC6A4 drug nicotine 18691405 Insertion/deletion polymorphism in the promoter region of the serotonin transporter gene (5 HTTLPR) has been linked to vulnerability to smoking and ability to quit. SLC6A4 drug nicotine 18691405 We aimed to determine whether 5 HTTLPR genotype is associated with smoking behavior in Caucasians from Northern Poland and to investigate other risk factors for tobacco smoking. SLC6A4 drug nicotine 18691405 5 HTTLPR genotypes were determined in 149 ever smokers (66 females; mean age 53.0 years) and 158 gender and ethnicity matched never smoking controls (79 females; mean age 45.0 years) to evaluate the association of this polymorphism with ever smoking status.

SLC6A4 drug cocaine 18581099 To study the rewarding and motivational properties of cocaine in the serotonin transporter knockout (SERT / ) rat and the involvement of compensatory changes in 5 HT1A receptor function are the objectives of the study. SLC6A4 drug cocaine 18581099 The SERT / rat was tested for cocaine induced locomotor activity, cocaine induced conditioned place preference, and intravenous cocaine self administration. SLC6A4 drug cocaine 18581099 Cocaine induced hyperactivity and conditioned place preference, as well as intravenous cocaine self administration were enhanced in SERT / rats. SLC6A4 drug cocaine 18581099 We further found that both 8 OHDPAT and S 15535 pretreatment increased low dose cocaine induced locomotor activity in SERT / rats, but not SERT+/+ rats. SLC6A4 drug cocaine 18581099 At a high cocaine dose, only SERT+/+ animals responded to 8 OHDPAT and S 15535.

SLC6A4 drug cocaine 17443127 The higher level of SERT availability in cocaine experienced monkeys may lead to a reduced inhibitory tone of 5 HT on the DA system, which may explain, in part, differences in the abuse liability between cocaine and MDMA.

SLC6A4 drug alcohol 17418697 In this preliminary study, possible alterations of [3H]citalopram binding to serotonin transporter (SERT) were evaluated in the NAC of Cloninger type 1 and 2 alcoholics (nine and seven subjects, respectively), and nonalcoholic controls (10 subjects) by human postmortem whole hemisphere autoradiography. SLC6A4 drug alcohol 17418697 In addition, there was a strong tendency toward a positive correlation between the SERT and dopamine transporter binding in the type 2 alcoholics, but not in the other groups.

SLC6A4 drug alcohol 17123474 Early alcohol use was predicted by maltreatment, 5 HTTLPR, and a gene by environment interaction, with increased risk for early alcohol use associated with the s allele. SLC6A4 drug alcohol 17117959 Increasing evidence supports a role for 5 hydroxytryptamine (5 HT) and the 5 HT transporter (5 HTT) in modulating the neural and behavioral actions of ethanol (EtOH) and other drugs of abuse. SLC6A4 addiction reward 17117959 Reward related effects of EtOH were assessed in 5 HTT KO mice using the conditioned place preference (CPP) paradigm. SLC6A4 drug alcohol 17117959 Data extend the finding that loss of 5 HTT gene function alters certain neural and behavioral effects of EtOH, with implications for better understanding the pathophysiology and treatment of alcoholism.

SLC6A4 drug cocaine 17105829 Last, the dose of RTI 336 that reduced cocaine maintained behavior by 50% (ED(50)) was coadministered with the selective serotonin transporter (SERT) inhibitors fluoxetine (3.0 mg/kg) and citalopram (3.0 mg/kg) to characterize their combined effects on cocaine self administration. SLC6A4 drug cocaine 17105829 Co administration of the ED(50) dose of RTI 336 in combination with either SERT inhibitor completely suppressed cocaine self administration without affecting DAT occupancy. SLC6A4 drug cocaine 17105829 Hence, at comparable levels of DAT occupancy, coadministration of SERT inhibitors with RTI 336 produced more robust reductions in cocaine self administration compared with RTI 336 alone. SLC6A4 drug cocaine 17105829 Collectively, the results indicate that combined inhibition of DAT and SERT warrants consideration as a viable approach in the development of cocaine medications.

SLC6A4 drug nicotine 16819620 Girls without the DRD4 7 repeat allele and who were homozygous for the long allele of 5 HTTLPR displayed the highest smoking and drinking activity. SLC6A4 drug alcohol 16775130 The 5 HT transporter (5 HTT) is the principle means of 5 HT reuptake in the brain and an obvious candidate mechanism for the effect of ethanol to inhibit 5 HT clearance. SLC6A4 drug alcohol 16775130 However, our second major finding was that genetic inactivation of the 5 HTT in a knock out mouse not only failed to prevent ethanol induced inhibition of 5 HT clearance, but actually potentiated this effect. SLC6A4 drug alcohol 16775130 Ethanol induced inhibition of 5 HT clearance was also potentiated in nonmutant mice by cotreatment with a 5 HTT antagonist. SLC6A4 drug alcohol 16775130 Providing a link with potential behavioral manifestations of this neural phenotype, 5 HTT knock out mice also exhibited exaggerated sensitivity to behavioral intoxication, as assayed by the sedative/hypnotic effects of ethanol. SLC6A4 addiction intoxication 16775130 Providing a link with potential behavioral manifestations of this neural phenotype, 5 HTT knock out mice also exhibited exaggerated sensitivity to behavioral intoxication, as assayed by the sedative/hypnotic effects of ethanol. SLC6A4 drug alcohol 16775130 This clearly demonstrates that the 5 HTT is not necessary for the neural and behavioral effects of ethanol observed herein and that genetic or pharmacological inactivation of the 5 HTT unmasks involvement of other principle mechanisms. SLC6A4 drug alcohol 16775130 These data are intriguing given growing evidence implicating the 5 HTT in the pathophysiology and treatment of alcoholism and neuropsychiatric conditions frequently comorbid with alcoholism, such as depression. SLC6A4 drug cocaine 16754872 There are three known high affinity targets for cocaine: the dopamine transporter (DAT), the serotonin transporter (SERT), and the norepinephrine transporter (NET). SLC6A4 drug cocaine 16754872 Contrary to expectations, DAT knockout (DAT KO) mice and SERT or NET knockout mice still self administer cocaine and/or display conditioned place preference (CPP) to cocaine, which led to the reevaluation of the DA hypothesis and the proposal of redundant reward pathways.

SLC6A4 drug cocaine 16754872 This mouse model is unique in that it is specifically designed to differentiate the role of DAT from the roles of NET and SERT in cocaine induced biochemical and behavioral effects. SLC6A4 drug nicotine 16702982 To investigate the potential role of this polymorphism for smoking behavior, SLC6A4 genotypes were determined in two different studies, the SMOKING GENES case control study (470 current smokers and 419 subjects who had never smoked) and the cross sectional Ludwigshafen risk and cardiovascular health (LURIC) study (777 current smokers and 1178 subjects who had never smoked). SLC6A4 drug nicotine 16702982 In the SMOKING GENES case control study, SLC6A4 genotype frequencies were not statistically different between smokers (LL: 30.9%; LS: 46.8%; SS: 16.4%) and non smokers (LL: 36.3%; LS: 41.8%; SS: 14.3%; P=0.13). SLC6A4 drug nicotine 16702982 SLC6A4 genotypes were furthermore not associated with Fagerstrom Tolerance Questionnaire score, packyears, number of cigarettes smoked per day or previous attempts to quit smoking. SLC6A4 drug nicotine 16702982 We conclude that the SLC6A4 promoter polymorphism is not a major determinant of smoking behavior in Caucasian. SLC6A4 drug alcohol 16691130 The role of the human serotonin transporter protein (5 HTT) gene in psychiatric disorders suggests that its variation may influence the comorbidity pattern and the heterogeneity of alcoholism. SLC6A4 drug alcohol 16691130 The aim of the present study is to verify possible associations between the 5 HTTLPR control region polymorphism with alcoholism and comorbid disorders. SLC6A4 drug alcohol 16691130 They suggest a role of the 5 HTTLPR polymorphism in a group of comorbid disorders among alcohol dependent individuals, supporting a genetic influence in alcoholism heterogeneity. SLC6A4 drug alcohol 16679343 There were no significant differences in the genotype frequencies of the DRD2, ALDH2, 5 HTTLPR, and COMT polymorphisms between alcoholics with and without ADHD. SLC6A4 drug psychedelics 16574713 Because 5 HT transporters play a key element in the regulation of synaptic 5 HT transmission it may be important to control for the potential covariance effect of a polymorphism in the 5 HT transporter promoter gene region (5 HTTLPR) when studying the effects of MDMA as well as cognitive functioning. SLC6A4 drug psychedelics 16574713 The aim of the study was to investigate the effects of moderate and heavy MDMA use on cognitive function, as well as the effects of long term abstention from MDMA, in subjects genotyped for 5 HTTLPR. SLC6A4 drug psychedelics 16574713 No effect of 5 HTTLPR or gender on memory function or MDMA use was observed. SLC6A4 drug psychedelics 16510479 This longitudinal study investigated whether mood, cognition and central serotonin transporters (SERT) would deteriorate with continued MDMA use and whether or not they would recover over increasing periods of MDMA abstinence. SLC6A4 drug psychedelics 16510479 The availability of central SERT was assessed with positron emission tomography using the McN5652 ligand for all groups at t1, and only for the ecstasy user groups on follow ups. SLC6A4 drug psychedelics 16510479 Reduced SERT availability might be a transient effect of heavy ecstasy use, since it partially recovered as the current users reduced their MDMA use. SLC6A4 drug psychedelics 16434566 Adolescent MDMA exposure partially attenuated the hyperthermic effects of the PD 67 MDMA challenge, completely blocked the locomotor hypoactivity otherwise observed on the day after the challenge, and also prevented MDMA induced serotonin neurotoxicity assessed on PD 74 by measuring regional [(3)H]citalopram binding to the serotonin transporter (SERT).

SLC6A4 drug alcohol 16358330 In this study, possible alterations of [(3)H]citalopram binding to serotonin transporter (SERT) were evaluated in the dorsal striatum of Cloninger type 1 and 2 alcoholics, and nonalcoholic control subjects by postmortem whole hemisphere autoradiography in humans. SLC6A4 drug alcohol 16358330 The SERT binding was significantly lower ( 26%, effect size 1.74) in the caudate body of alcoholics. SLC6A4 drug alcohol 16358330 The SERT binding tended to be lower also in the other parts of the dorsal striatum in alcoholics, but the results did not reach significance. SLC6A4 drug alcohol 16358330 In addition, there was a significant positive correlation, especially in type 1 alcoholics, between the SERT binding in the body of the caudate and in the perigenual anterior cingulate cortex, an area in which the SERT binding has been shown to be lower among alcoholics. SLC6A4 drug alcohol 16358330 These results give preliminary evidence to suggest that the SERT binding in the dorsal striatum may be lower in alcoholics, and that the serotonergic system may be affected in cortical and striatal areas simultaneously. SLC6A4 drug cocaine 16337262 Using the conditioned taste aversion (CTA) preparation, the present study examined the role of monoamine uptake inhibition in cocaine's aversive effects by comparing cocaine to three reuptake inhibitors with relative specificity for the transporters of dopamine (DAT; GBR 12909), norepinephrine (NET; desipramine) and serotonin (SERT; clomipramine).

SLC6A4 addiction dependence 16025417 The loudness dependence (LD) of the auditory evoked N1/P2 component has been related to serotonergic neurotransmission, i. e. the allelic variants in the promoter of the 5 hydroxytryptamine transporter (5 HTT) gene (SCL6A4). SLC6A4 drug nicotine 16025417 Moreover, smoking behavior has been associated to the 5 HTT genotype. SLC6A4 drug nicotine 16025417 It was hypothesized that cigarette smoking modulates the LD and this effect was expected to interact with the 5 HTT genotype. SLC6A4 drug nicotine 16025417 5 HTT genotype and LD were determined in 63 healthy smokers and 114 nonsmokers. SLC6A4 drug nicotine 16025417 LD was significantly affected by smoking status (p = 0.008) and 5 HTT genotype (p = 0.045) but not by smoking*genotype interaction or daily cigarette consumption. SLC6A4 drug nicotine 16025417 5 HTT genotype showed no significant effect on smoking behavior. SLC6A4 drug nicotine 16025417 The results indicate a higher serotonergic activity in smokers as compared to nonsmokers independent of 5 HTT genotype.

SLC6A4 drug alcohol 15834221 The purpose of the present study was to investigate possible interactions between a polymorphism in the promoter region of the serotonin transporter (5 HTT) gene and family relations on adolescent alcohol consumption. SLC6A4 drug alcohol 15834221 5 HTT genotype (p=0.029) and family relations (p=0.022) predicted alcohol consumption independently as well as through an interaction with one another (p=0.05). SLC6A4 addiction intoxication 15834221 In a binary logistic model, we found that adolescents with the LS variant of the 5 HTT gene and with family relations being "neutral" or "bad" had a 12 to 14 fold increased risk for high intoxication frequency. SLC6A4 drug alcohol 15834221 In sum, our results show that a functional polymorphism of the 5 HTT genotype, family relations, and interactions between these variables predict adolescent alcohol consumption in a randomized sample of adolescents. SLC6A4 drug psychedelics 15831439 MDMA and eight chemically defined byproducts of MDMA synthesis were investigated for their interaction with the primary sites of action of MDMA, namely the human plasmalemmal monamine transporters for norepinephrine, serotonin, and dopamine [(norepinephrine transporter (NET), serotonin transporter (SERT), and dopamine transporter (DAT)]. SLC6A4 drug psychedelics 15831439 MDMA induced release mediated by NET, SERT, or DAT with EC50 values of 0.64, 1.12, and 3.24 microM, respectively.

SLC6A4 drug alcohol 15520362 We wanted to determine whether serotonin transporter gene promoter variation (rh 5HTTLPR) and rearing condition would interact to influence alcohol preference in female rhesus macaques. SLC6A4 drug alcohol 15345266 DRD2A, DRD2B, GABB2, EAAT2, and 5HTT genotypes did not divide alcoholic cases and controls on N methyl d aspartate (NMDA) receptor parameters.

SLC6A4 drug cocaine 15226739 To help determine mechanisms underlying these effects, we now report examination of baselines and drug induced changes of extracellular dopamine (DAex) and serotonin (5 HT(ex)) levels in microdialysates from nucleus accumbens (NAc), caudate putamen (CPu), and prefrontal cortex (PFc) of wild type, homozygous DAT or SERT KO and heterozygous or homozygous DAT/SERT double KO mice, which are differentially rewarded by cocaine. SLC6A4 drug cocaine 15226739 Adding SERT to DAT deletion attenuates the cocaine induced DAex increases found in CPu, but not those found in PFc. SLC6A4 drug cocaine 15226739 The selective SERT blocker fluoxetine increases DAex in CPu of DAT KO mice, while cocaine and the selective DAT blocker GBR12909 increase 5 HT(ex) in CPu of SERT KO mice. SLC6A4 drug cocaine 15226739 These data provide evidence that (a) cocaine increases DAex in PFc independently of DAT and that (b), in the absence of SERT, CPu levels of 5 HT(ex) can be increased by blocking DAT. SLC6A4 drug cocaine 15226739 Cocaine induced alterations in CPu DA levels in DAT , SERT , and DAT/SERT double KO mice appear to provide better correlations with cocaine CPP than cocaine induced DA level alterations in NAc or PFc.

IL6 drug alcohol 31437534 Accumulating evidence from preclinical and clinical studies has implicated a role for the cytokine IL 6 in a variety of CNS diseases including anxiety like and depressive like behaviors, as well as alcohol use disorder. IL6 drug alcohol 31398460 We hypothesized that chronic alcohol consumption impairs memory and increases the inflammatory cytokines TNFα, IL6, MCP1, and IL1β in the hippocampus and prefrontal cortex regions in the brain. IL6 drug alcohol 31373129 Subsequent epigenetic (chromatin immunoprecipitation [ChIP] sequencing) analysis showed that alcohol induced changes in H3K27me3 were significantly enriched at genes in the IL 6 signaling pathway, consistent with the well characterized role of KDM6B in modulation of inflammatory responses.

IL6 addiction reward 31333427 Following CPP, biological samples were taken to measure striatal levels of interleukin 6 (IL 6) and plasmatic levels of oxytocin (OT). IL6 addiction reward 31333427 Our results confirmed that ISD animals housed in standard condition displayed an anxious phenotype, developed CPP and had increased levels of IL 6 in the striatum. IL6 drug amphetamine 31282647 Systemically administered METH (1 mg/kg) was found to specifically up regulate expression of both CD11b (microglial activation marker) and the proinflammatory cytokine interleukin 6 (IL 6) mRNAs in the ventral tegmental area (VTA), but not in either the nucleus accumbens shell (NAc) or prefrontal cortex (PFC). IL6 drug amphetamine 31282647 Systemically administered METH (1 mg/kg) was found to specifically up regulate expression of both CD11b (microglial activation marker) and the proinflammatory cytokine interleukin 6 (IL 6) mRNAs in the ventral tegmental area (VTA), but not in either the nucleus accumbens shell (NAc) or prefrontal cortex (PFC). IL6 drug amphetamine 31282647 Systemic administration of a nonopioid, blood brain barrier permeable TLR4 antagonist (+) naloxone inhibited METH induced activation of microglia and IL 6 mRNA overexpression in VTA. IL6 drug opioid 31282647 Systemic administration of a nonopioid, blood brain barrier permeable TLR4 antagonist (+) naloxone inhibited METH induced activation of microglia and IL 6 mRNA overexpression in VTA. IL6 drug amphetamine 31282647 Furthermore, intra VTA injection of LPS RS or IL 6 neutralizing antibody suppressed METH induced elevation of extracellular NAc dopamine. IL6 drug amphetamine 31282647 Taken together, this series of studies demonstrate that METH induced neuroinflammation is, at least in part, mediated by TLR4 IL6 signaling within the VTA, which has the downstream effect of elevating dopamine in the NAc shell. IL6 drug alcohol 31167126 Our results revealed that ethanol challenge overtly compromised echocardiographic, cardiomyocyte contractile, intracellular Ca2+ and ultrastructural properties along with overt apoptosis, inflammation (elevated MIF, IL 1β and IL 6) and mitochondrial O2 production (p < 0.01), the effect of which was reconciled by CD74 ablation (p < 0.01 vs. ethanol group) with the exception of MIF expression. IL6 drug nicotine 31079306 In stratified models, gender, age, smoking status, and hypertension only led to small modifications in effect estimates, though a few of the estimates for IL 6 and TNF α became non significant. IL6 drug amphetamine 31078920 We found that METH exposure increased LPS induced IL 6 and TNF α production in the Hip, CPU and NAc regions. IL6 addiction reward 30858110 Male and female mice were fed a HFD for 18 weeks, followed by quantitation of glucose tolerance, inflammatory markers of brain tissue (TNFα, IL 6, IL 1β, Iba 1), neural excitability in the prelimbic cortex (PLC), as well as assessment of emotional reactivity and hedonic behavior in a battery of behavioral tests. IL6 drug alcohol 30808184 This demonstrates a particular sensitivity of adolescents to alcohol associated cues and neuroimmune learning, whereas prior work indicated that adults require multiple pairings of ethanol to the CS in order to achieve a conditioned amygdala IL 6 response. IL6 drug alcohol 30803859 The expression of Lcn2 was increased by ethanol treatment, despite unchanged expression of pro inflammatory cytokines Tnfα, Il6 and Il 1β.

IL6 addiction reward 30634502 We found that LDOC1 deficiency led to reinforcing a reciprocal loop of IL 6/JAK2/STAT3, through which LDOC1 mediates the cancer progression. IL6 drug nicotine 30634502 Overall, our results elucidated a crucial role of LDOC1 in lung cancer and revealed how LDOC1 acts as a bridge between tobacco exposure and the IL 6/JAK2/STAT3 loop in this human malignancy. IL6 addiction intoxication 30625475 Binge like consumption resulted in a 67% decrease in IL 10 immunoreactivity but had no effect on IL 4 or IL 6 compared with the water drinking control group.

IL6 addiction withdrawal 30472309 Recent studies have demonstrated brain cytokine fluctuations associated with acute ethanol intoxication (increased IL 6) and withdrawal (increased IL 1β and TNFα). IL6 drug alcohol 30472309 We utilized two tests of ethanol sensitivity to establish a potential role for IL 6 after high (3.5 4.0 g/kg, intraperitoneally [i.p.]) IL6 drug alcohol 30472309 In the first experiments, rats were infused with 25, 50, 100, or 200 ng of IL 6; or 0.3, 3.0, or 9.0 μg of the JAK/STAT inhibitor AG490 30 min prior to a high dose ethanol challenge. IL6 addiction aversion 30472309 Next, we assessed whether IL 6 was sufficient to produce a CTA. IL6 drug alcohol 30472309 Overall, these studies suggest that IL 6 had only a minor influence on ethanol induced behavioral changes, yet phenotypic differences in sensitivity to IL 6 were apparent. IL6 drug alcohol 30472309 These studies are among the first to examine a potential functional role for IL 6 in ethanol related behaviors, and may have important implications for understanding the relationship between acute ethanol intoxication and its associated behavioral alterations.

IL6 drug alcohol 30447270 Effect of alcohol on the interleukin 6 mediated inflammatory response in a new mouse model of acute on chronic liver injury. IL6 drug alcohol 30368255 Acute on chronic alcohol did not induce serum TNFα, IL 6, and IL 1β. IL6 addiction intoxication 30257399 Administration of PD prior to APAP intoxication significantly ameliorated the increase in serum transferases, interleukin 1β (IL 1β), IL 6, tumor necrosis factor alpha (TNF α), and hepatic malondialdehyde (MDA) and the depletion of glutathione (GSH) in mice. IL6 drug nicotine 30218019 Hyperalgesia induced by PSD prevailed over the antinociceptive action of nicotine, while the association between PSD and ABST synergistically increased IL 6 concentrations and decreased pain threshold. IL6 drug nicotine 30217256 Our data revealed that nicotine induced renal dysfunction manifested by significant abnormal levels of kidney function markers (creatinine and urea) accompanied by increased levels of oxidative stress biomarker (malondialdehyde) and inflammatory markers (nitric oxide, Interleukin 6 and tumor necrosis factor α) while antioxidant status as glutathione level and glutathione S transferase activity were found to be decreased significantly as compared with controls. IL6 drug cannabinoid 30046349 Δ9 THC/sesame oil therapy showed similar effects to MTX in neutralizing the inflammatory process of AIA, through attenuating erythrocyte sedimentation rate (ESR) scores and proinflammatory cytokines, including tumor necrosis factor alpha (TNF α), interleukin 1 beta (IL 1β), and interleukin 6 (IL 6) levels, to normal values.

IL6 addiction intoxication 29685140 On the other hand, ethanol intoxication caused the increase of serum TNFα, IL 8, IL 6 and 1Lβ, markers of tissue inflammation. IL6 drug opioid 29657246 The aim of the current study was to investigate the effects of those two modalities on pain behavior and the expression of pro inflammatory cytokines such as interleukin (IL) 1β and IL 6 and tumor necrosis factor α (TNF α) in the spinal cord and dorsal root ganglion (DRG) in a rat model of perioperative fentanyl induced hyperalgesia. IL6 drug cannabinoid 29607409 The THC+CBD strain was also associated with less desire to smoke, lower levels of subjective drug effects, and lower levels of circulating cytokines (TNF α, IL 6, and IL 1β) immediately after use. IL6 drug nicotine 29578441 In the blood serum of all age groups of rats, pronounced changes in IL 6 content were observed on the 45th day of exposure to tobacco smoke. IL6 drug alcohol 29576702 EALT supplementation prevented alcoholic liver injury through attenuation of inflammatory mediators such as toll like receptor 4, cytochrome P4502E1, and cyclooxygenase 2, and inflammatory cytokine interleukin 6. IL6 drug alcohol 29500107 Among people with only an alcohol use disorder, IL 6 was positively associated with depression and psychological distress scores, and IL 10 was negatively associated with anxiety score. IL6 drug alcohol 29458194 In non stressed controls, acute ethanol increased expression of Il 6 and IκBα in the hippocampus. IL6 drug alcohol 29458194 In contrast, rats exposed to footshock 24 h prior to ethanol demonstrated potentiation of hippocampal Il 6 and IκBα expression relative to ethanol exposed non stressed controls. IL6 drug alcohol 29458194 As expected, acute ethanol increased Il 6 expression in all structures examined, yet the Il 6 response was attenuated exclusively in the hippocampus in chronically stressed rats. IL6 drug alcohol 29458194 Together, these experiments demonstrate an intriguing interaction between recent stress history and ethanol induced increases in hippocampal Il 6, and may provide insight into novel pharmacotherapeutic targets for prevention and treatment of alcohol related health outcomes based on stress susceptibility. IL6 drug alcohol 29445009 In vivo and in vitro binge alcohol exposure significantly inhibited the TLR4 MyD88 cytokines TNF α and IL 6, as well as the TLR4 TRIF cytokines/chemokines IFN β, IP 10, and RANTES, in human monocytes, but not TLR3 TRIF induced cytokines/chemokines, as detected by quantitative PCR and ELISA.

IL6 drug alcohol 29369159 Multiple linear regression models adjusted for age, antiretroviral therapy regimen, CD4 T cell count, interleukin 6, and alcohol use severity. IL6 drug alcohol 29306704 While a subset of IEGs encoding for effector proteins (such as Bdnf, InhbA and Dusp5) were downregulated by ethanol, others (such as Il 6) were unaffected. IL6 drug alcohol 29178411 We found that during abstinence, alcohol binge drinkers had elevated plasma levels of oleoylethanolamide, palmitoleoylethanolamide, arachidonoylethanolamide, dihomo γ linolenoyl ethanolamide and linoleoyl ethanolamide, which positively correlated with changes in the mRNA expression of key inflammatory markers in peripheral blood mononuclear cells, such as toll like receptors (TLR4), pro inflammatory cytokines/chemokines interleukin 1 beta, interleukin 6 and monocyte chemoattractant protein 1, and cyclooxygenase 2.

IL6 drug opioid 29135586 In this study, we tried to investigate behavioral hyperalgesia, the expression of proinflammatory cytokines, such as interleukin 1β (IL 1β), interleukin 6 (IL 6), and tumor necrosis factor α (TNF α), and the activation of microglia in the spinal cord and dorsal root ganglion (DRG) in a rat model of surgical plantar incision with or without perioperative fentanyl. IL6 drug opioid 29135586 The fentanyl or surgical incision upregulated the expression of IL 1β, IL 6, and TNF α in the spinal cord and bilateral DRG for more than 7 days and increase of ionized calcium binding adapter molecule 1 in the spinal cord. IL6 drug opioid 29135586 The combination of fentanyl and incision resulted in higher increase of IL 1β, IL 6, and TNF α in the spinal cord and bilateral DRG. IL6 drug opioid 29135586 The surgical plantar incision with or without perioperative fentanyl induced significant mechanical and thermal hyperalgesia, an increased expression of IL 1β, IL 6, TNF α in the spinal cord and DRG, and activation of microglia in the spinal cord. IL6 drug opioid 29111854 We observed differential methylation of Bdnf and Il6 in the pons, Nr3c1 in the cerebellum, and Il1b in the hippocampus in response to acute morphine exposure (all P value < 0.05). IL6 addiction intoxication 28840951 Finally, higher levels of inflammatory markers, mainly monocyte chemoattractant protein 1, as well as LPS, high mobility group box 1, toll like receptor 4, IL 6 and ciclooxygenase 2, correlated with worse scores on episodic memory and executive functioning tasks in female binge drinkers but not in male binge drinkers. IL6 drug cannabinoid 28821005 This cannabinoid also prevented PTZ induced EEG activity and interleukin 6 increase in prefrontal cortex. IL6 drug alcohol 28806641 A significant difference in the cytokine profile was still observed 24h post injury in the ethanol pretreated mice, as shown by the delayed peak in IL 6 and by the suppression of GM CSF, IFN γ, and IL 3. IL6 drug opioid 28697991 In the morphine abuser, a decrease in pain threshold, an increase in IL 6 and a decrease in IL 10 levels were evident compared with non abuser subjects. IL6 drug alcohol 28669319 Our aim is to describe changes in serum concentration for the pro inflammatory factors TNF α, IFN γ, IL 1β, IL 8, IL 6, IL 10, IL 12 and MCP 1, for the satiety factor leptin and for factors associated with neuronal changes, neuron specific enolase (NSE) and glial activation S100 beta protein (S100 β), and explore their association with abstinence in alcohol dependent subjects after withdrawal.

IL6 drug alcohol 28669319 The levels of TNF α, IL 1β, IL 8, IL 6, IL 12, MCP 1, and leptin decreased after withdrawal and remained low until M6, regardless of alcohol consumption. IL6 addiction withdrawal 28669319 The levels of TNF α, IL 1β, IL 8, IL 6, IL 12, MCP 1, and leptin decreased after withdrawal and remained low until M6, regardless of alcohol consumption. IL6 drug amphetamine 28621212 Meth upregulated the gene expression of IL 6, IL 1β, and TNFα and downregulated the expression of Arg 1, IL 10, and KLF4. IL6 drug alcohol 28430931 In this study we investigated a possible association between alterations in the methylation of the BDNF IV/NGF I gene promoter and the cytokines tumor necrosis factor α (TNF α) and interleukin 6 (IL 6) in 55 male alcohol dependent patients. IL6 drug alcohol 28430931 In this study we investigated a possible association between alterations in the methylation of the BDNF IV/NGF I gene promoter and the cytokines tumor necrosis factor α (TNF α) and interleukin 6 (IL 6) in 55 male alcohol dependent patients. IL6 addiction withdrawal 28430931 Moreover, mean methylation of the NGF I promoter was significantly associated with the IL 6 serum levels and STAI I score during withdrawal (P < 0.001). IL6 drug alcohol 28319836 The hippocampus revealed age dependent shifts in cytokine expression (IL 6, IL 1β, and monocyte chemoattractant protein 1), but no changes were observed in the PVN at baseline or following ethanol. IL6 drug alcohol 28242869 Peripheral monocyte response to lipopolysaccharide stimulation was lower in alcohol dependent subjects compared with controls for the proinflammatory cytokines interleukin 6 and interleukin 8. IL6 drug alcohol 28201924 Re exposure to the odor CS significantly increased IL 6 levels in HPC and AMG, an effect only evident in paired rats administered ethanol i.p. IL6 drug alcohol 28201924 Overall, this study suggests that ethanol exposure can regulate the levels of IL 6 at HPC and AMG via classical conditioning mechanisms. IL6 drug alcohol 28201924 The main new finding of the present study was that, after four pairings of ethanol's unconditioned effects and a distinctive odor, the latter CS increased IL 6 levels in HPC and AMG. IL6 drug alcohol 28201924 This suggests that ethanol's effects upon IL 6 in HPC and AMG may come under conditioned control, particularly after repeated pairings between distinctive odor cues and ethanol's effects. IL6 drug nicotine 28197102 We found that right cervical vagotomy inhibited the cholinergic anti inflammatory pathway, aggravated myocardial lesions, up regulated the expression of TNF α, IL 1β, and IL 6, and worsened the impaired left ventricular function in murine viral myocarditis, and these changes were reversed by co treatment with nicotine by activating the cholinergic anti inflammatory pathway. IL6 drug opioid 28178176 In response to LPS, there was a significant increase in the expression of the pro inflammatory cytokine/chemokine genes interleukin 1 beta (Il 1β), interleukin 6 (Il 6), C C motif chemokine ligand 2 (Ccl2), C C motif chemokine ligand 7 (Ccl7), C X C motif chemokine ligand 1 (Cxcl1), and C X C motif chemokine ligand 3 (Cxcl3) and a significant decrease in the anti inflammatory NLRP12 gene in both morphine tolerant and placebo control rats compared to saline treated rats, although the changes were greater in the placebo control animals. IL6 drug opioid 28178176 In response to LPS, there was a significant increase in the expression of the pro inflammatory cytokine/chemokine genes interleukin 1 beta (Il 1β), interleukin 6 (Il 6), C C motif chemokine ligand 2 (Ccl2), C C motif chemokine ligand 7 (Ccl7), C X C motif chemokine ligand 1 (Cxcl1), and C X C motif chemokine ligand 3 (Cxcl3) and a significant decrease in the anti inflammatory NLRP12 gene in both morphine tolerant and placebo control rats compared to saline treated rats, although the changes were greater in the placebo control animals.

IL6 drug alcohol 26707655 Recent studies show that ethanol can activate cells of the neuroimmune system, resulting in the elevated production of neuroimmune factors, including the cytokine interleukin 6 (IL 6). IL6 drug alcohol 26707655 Here we analyzed the consequences of this CNS action of ethanol using transgenic mice that express elevated levels of IL 6 through increased astrocyte expression (IL 6 tg) to model the increased IL 6 expression that occurs with ethanol use. IL6 drug alcohol 26707655 Results show that increased IL 6 expression induces neuroadaptive changes that alter the effects of ethanol.

IL6 drug cocaine 21277908 Interestingly, pretreatment with memantine at the lowest effective dose (0.02 mg/kg/injection) reversed cocaine conditioning enhanced IL 6 and decreased TNF α levels in these brain regions. IL6 drug cocaine 21277908 Finally, intra mPFC infusion of recombinant IL 6, but not thalidomide, reversed memantine (0.02 mg/kg/injection × 6) decreased cocaine induced CPP. IL6 addiction reward 21277908 Finally, intra mPFC infusion of recombinant IL 6, but not thalidomide, reversed memantine (0.02 mg/kg/injection × 6) decreased cocaine induced CPP.

IL6 drug alcohol 21143255 Human PBMCs were cultured in the presence of 100 mM ethanol and/or 100 ng/ml LPS for various time periods (1, 3, 8, and 24 hours) and analyzed for the kinetics of gene expression by quantitative real time PCR of selected transcription factors (T bet, GATA3, Foxp3, and RORγt) and cytokines (TNF α, IL 6, IL 10, and IFN γ). IL6 drug alcohol 21143255 Markers of inflammation including TNF α and IL 1β in supernatant of PBMCs were significantly decreased, while levels of IL 10 and IL 6 remained unchanged following ethanol exposure. IL6 drug nicotine 21078494 Nicotine did not cause an excessive expression of TNF α, IL 8, and IL 6, nor did it affect protein production from the MUC5AC gene. IL6 drug nicotine 21078494 Nicotine not only failed to stimulate production of TNF α, IL 8, and IL 6, but its presence was shown to suppress the activation resulting from exposure to CE and LPS (P < 0.05). IL6 drug alcohol 20608903 Consistent with these findings, pulmonary levels of KC and IL 6 were increased in wild type mice following burn and ethanol compared to burn injury alone as well as to their TLR4 knockout counterparts.

IL6 drug nicotine 18536030 Serum IL 6 level was also a significant independent predictor of poor survival (HR = 1.22; 95% CI, 1.02 to 1.46; P = .03), as were older age, smoking, cancer site (oral/sinus), higher cancer stage, and comorbidities. IL6 addiction relapse 18536030 Using IL 6 as a biomarker for recurrence and survival may allow for earlier identification and treatment of disease relapse. IL6 drug opioid 18294378 Mice treated chronically treated with morphine prior to incision were found to have enhanced skin levels of IL 1beta, IL 6, G CSF, KC and TNFalpha after incision at one or more time points compared to saline pretreated controls. IL6 drug alcohol 17980786 Alcohol induced endothelial damage or protection may be related to the synthesis or action of several markers, such as nitric oxide, cortisol, endothelin 1, adhesion molecules, tumor necrosis factor alpha, interleukin 6, C reactive protein, and haemostatic factors. IL6 addiction withdrawal 17637925 Pooled results show an increase in IL 6 when concentrations of PNC were elevated 12 17 hr before blood withdrawal [percent change of geometric mean, 2.7; 95% confidence interval (CI), 1.0 4.6]. IL6 drug alcohol 17374050 While T x Hem did not prevent LPS induced release of TNF alpha, IL 1alpha, IL 6, or IL 10 at 6 or 24 hours, alcohol binge suppressed TNF alpha, IL 1 and IL 6 release, without altering IL 10 response in cells isolated from blood and pleural compartment. IL6 addiction intoxication 17374050 While T x Hem did not prevent LPS induced release of TNF alpha, IL 1alpha, IL 6, or IL 10 at 6 or 24 hours, alcohol binge suppressed TNF alpha, IL 1 and IL 6 release, without altering IL 10 response in cells isolated from blood and pleural compartment. IL6 drug opioid 17201885 Leukocyte subpopulation NK, CD4+, CD8+ and some cytokines Th1 (IFNgamma, interleukin [IL]2) and Th2 (IL 6, IL 10) were evaluated prior to, during and after methadone treatment. IL6 drug cocaine 17068203 In cocaine dependent volunteers and control subjects, we analyzed monocyte TNF alpha and IL 6 expression at rest and in response to the bacterial ligand, lipopolysaccharide (LPS), over a 24 h period. IL6 drug cocaine 17068203 In addition, the in vivo effects of cocaine (40 mg) versus placebo on monocyte expression of TNF alpha and IL 6 were profiled over 48 h. Cocaine dependent volunteers showed a decrease in the capacity of monocytes to express TNF alpha and IL 6 compared with control subjects. IL6 drug alcohol 16783199 Only the hemorrhage induced rise in lung IL 6 and tumor necrosis factor alpha was prevented by alcohol administration.

IL6 drug nicotine 16332510 Results showed that nicotine suppressed the LPS induced production of IL 6 and IL 8 in both cell lines. IL6 drug alcohol 16295318 For this reason, 153 patients with chronic alcoholism were divided into four test lots, in order to determine: the activity and the serum level of ceruloplasmin, plasma level of MDA (malondialdehyde), lactic and pyruvic acids, serum level of transferrin, alpha1 antitrypsin, CRP (C reactive protein), C3 fraction of the complement, IgA, IgG, IgM, IL 1beta, IL 6 and IL 8, cytosolic level of the cytochrome c in the circulating leukocytes. IL6 drug alcohol 16295318 On the other hand, the ethanol induced apoptosis of leukocytes (especially of the B cells) is very important, probably due to the absence of IL 6 protective action on these cells. IL6 addiction intoxication 16046881 EtOH intoxication two hr before LPS acutely suppressed the increased IL 6 mRNA in all tissues and antagonized the increase in plasma and tissue IL 6 protein concentration. IL6 drug alcohol 15469574 In early septic shock, chronic alcoholic patients had significantly decreased levels of IL 1beta (P < 0.015), IL 6 (P < 0.016) and IL 8 (P < 0.010). IL6 drug alcohol 15289211 In 36 alcoholics without liver disease, at the point of commencing withdrawal from alcohol, the following measures of immune competence were measured: the immunophenotypes of cells, acute phase proteins, the endotoxin neutralizing capacity (ENC) of the serum, titers of anti lipopolysaccharide (LPS) antibodies, and ex vivo cytokine inducibility in T cells and monocytes (TNFalpha, IL1beta, IL1RA, IL4, IL6, IL8, IL10 and IL12).

IL6 addiction relapse 11293664 The mRNA for cytokines IL 1beta, IL 6, IL 10 and the chemokines CINC, MIP 1alpha, MCP 1 were significantly (P < 0.05) elevated and persisted for 2 weeks, decreased in 6 weeks and increased again during relapse. IL6 drug alcohol 11109026 Acute ethanol exposure prior to burn injury increases the immune dysfunction seen with burn alone, which has been partially attributed to increased circulating and splenic macrophage production of interleukin 6 (IL 6). IL6 drug alcohol 11109026 Acute ethanol exposure prior to burn injury increases the immune dysfunction seen with burn alone, which has been partially attributed to increased circulating and splenic macrophage production of interleukin 6 (IL 6). IL6 drug alcohol 11109026 Interestingly, the increase in macrophage IL 6 secretion seen at the moderate dose was not augmented at the high dose; however, the circulating IL 6 levels did reveal a further increase at the high ethanol dose. IL6 drug alcohol 11109026 These results suggest that the dose dependent effects of ethanol on immunity following burn injury are not the result of splenic macrophage IL 6 production as shown at the moderate dose and that the immune suppressive effects of ethanol in this model persist after it is cleared from the circulation.

IL6 addiction sensitization 10575098 The ability of acute IL 6 injections to alter locomotor activity and the ability of repeated IL 6 injections to produce long lasting sensitization to the locomotor stimulating effects of amphetamine suggest an interaction of this cytokine with the mesolimbic dopamine system, a system implicated in aspects of schizophrenia, addiction, and movement disorders. IL6 drug amphetamine 10575098 The fact that IL 6 caused a lasting change in responsiveness to amphetamine implies a mechanism by which immunogenic stimuli can alter brain circuitry, changing its sensitivity to seemingly unrelated subsequent stimuli or events.

IL6 drug alcohol 8730220 Interleukin 6 tumor necrosis factor alpha clearance and metabolism in vivo and by the isolated, perfused liver in the rat: effect of acute alcohol administration. IL6 drug alcohol 8730220 Acute ethanol administration significantly increased plasma clearance rate for both cytokines (36% and 72%, for IL 6 and TNF alpha, respectively), decreased the t1/2 alpha (30% and 11%, for IL 6 and TNF alpha, respectively), abolished the slow (beta) phase component for TNF alpha, and increased t1/2 beta for IL 6 (31%). IL6 drug alcohol 8730220 Although alcohol did not affect organ distribution of TNF alpha, it increased the IL 6 content in the liver, kidney, and blood. IL6 drug alcohol 8730220 Ethanol addition to the perfusate (35 mM, final concentration) significantly increased TNF alpha uptake (24%), without affecting IL 6 uptake or the degradation rate of either cytokine. IL6 drug alcohol 8730220 Data presented in this study demonstrate that: (1) acute alcohol consumption can alter the kinetic behavior of IL 6 and TNF alpha in the bloodstream, mainly by accelerating their clearance which, in turn, may counteract the outcome of cytokine secretion and delivery to the blood; and (2) short exposure of liver to ethanol levels commonly seen in humans after binge drinking may alter its capacity to take up cytokines.

NPY drug alcohol 16192983 On the other hand, infusion of PKA activator (Sp cAMP) or NPY alone into the NAc shell did not produce any changes in alcohol intake; however, when these agents were coinfused with PKA inhibitor, they significantly attenuated the increases in alcohol preference induced by pharmacological inhibition of PKA. NPY drug alcohol 16192983 Furthermore, decreased function of PKA may regulate alcohol drinking behaviors via CREB mediated decreased expression of NPY in the NAc shell of rats.

NPY drug alcohol 16023707 Sensitized effects of neuropeptide Y on multiple ingestive behaviors in P rats following ethanol abstinence.

NPY drug alcohol 16023707 Following intracerebroventricular cannula implantation during the third period of ethanol abstinence, groups (n=12 13/dose) were infused with NPY (2.5, 5.0, 10.0 microg) or aCSF prior to ethanol reinstatement. NPY addiction relapse 16023707 Following intracerebroventricular cannula implantation during the third period of ethanol abstinence, groups (n=12 13/dose) were infused with NPY (2.5, 5.0, 10.0 microg) or aCSF prior to ethanol reinstatement. NPY drug alcohol 16023707 Two additional groups (n=11 12/dose) were treated similarly except that ethanol access was uninterrupted, and they were infused with a single NPY dose (10.0 microg) or aCSF. NPY drug alcohol 16023707 NPY increased food intake in all groups, and this effect was greater following ethanol abstinence. NPY drug alcohol 16023707 NPY suppressed ethanol intake, and this suppression lasted longer (24 h post infusion) in rats with a history of ethanol abstinence periods than rats with a history of continuous ethanol access (4 h post infusion). NPY drug alcohol 16023707 These results confirm past findings and indicate that global dysregulation of brain NPY systems during ethanol abstinence may render P rats more sensitive to the behavioral effects of NPY. NPY drug amphetamine 15985714 Amphetamine induced effects on neuropeptide Y in the rat brain. NPY drug amphetamine 15985714 Repeated (+) amphetamine sulfate (AMPH) administration (5 mg/kg sc twice daily for 6 days and once on day 7) markedly and reversibly decreased (until 96 h after the final dose) neuropeptide Y like immunoreactivity (NPY LI) in the rat striatum (caudate putamen) and nucleus accumbens, and had no effect on NPY LI in the hippocampus. NPY drug amphetamine 15985714 Repeated (+) amphetamine sulfate (AMPH) administration (5 mg/kg sc twice daily for 6 days and once on day 7) markedly and reversibly decreased (until 96 h after the final dose) neuropeptide Y like immunoreactivity (NPY LI) in the rat striatum (caudate putamen) and nucleus accumbens, and had no effect on NPY LI in the hippocampus. NPY drug amphetamine 15985714 No significant alterations were detected in the hybridization signal of NPY mRNA4 and 24 h after the end of AMPH treatment. NPY drug amphetamine 15985714 A single dose of AMPH (5 mg/kg sc) administered to rats 4 and 24 h prior to sacrifice had no effect on NPY LI in the brain structures studied. NPY drug amphetamine 15985714 Moreover, AMPH injected 8 days after the last dose of repeated AMPH administration did not change NPY LI up to 72 h. The minimal dose of haloperidol, the strong mixed dopaminergic D2/D1 receptor antagonist, (0.75 mg/kg injected ip 30 min before each of the multiple AMPH administrations) that was sufficient to completely block stereotypy and hyperlocomotion elicited by multiple AMPH administrations enhanced the AMPH induced decrease in the striatal and accumbens NPY LI. NPY drug amphetamine 15985714 Our results suggest that NPY neurons in the striatum, nucleus accumbens and hippocampus are not directly involved in the acute behavioral response to AMPH (stereotypy and hyperlocomotion) as well as in the initiation and expression of AMPH induced behavioral sensitization.

NPY drug alcohol 15582675 Allostasis and dysregulation of corticotropin releasing factor and neuropeptide Y systems: implications for the development of alcoholism. NPY drug alcohol 15582675 With regard to alcohol, two neuropeptides appear to be involved in the regulation of alcohol related stress, corticotropin releasing factor (CRF), which is associated with an increased stress response and negative affect, and neuropeptide Y (NPY), a neuropeptide with anxiolytic properties.

NPY drug alcohol 15582675 The hypothesis to be developed in the present review is that a dysregulation of the CRF and NPY systems significantly contributes to the motivational basis of continued alcohol seeking behavior during alcohol dependence.

NPY addiction relapse 15582675 The hypothesis to be developed in the present review is that a dysregulation of the CRF and NPY systems significantly contributes to the motivational basis of continued alcohol seeking behavior during alcohol dependence. NPY drug alcohol 15582675 It appears that increases in CRF contribute to the negative affective state that is strongly associated with alcohol withdrawal, and NPY provides a motivational basis to consume alcohol because the anxiolytic effects of alcohol, which are strongly associated with relapse, appear to be regulated in part by this neuropeptide. NPY addiction relapse 15582675 It appears that increases in CRF contribute to the negative affective state that is strongly associated with alcohol withdrawal, and NPY provides a motivational basis to consume alcohol because the anxiolytic effects of alcohol, which are strongly associated with relapse, appear to be regulated in part by this neuropeptide.

NPY drug alcohol 15567472 NPY knockout mice drink more alcohol than wild type mice, implicating a link between NPY deficiency and high alcohol intake. NPY drug alcohol 15567472 This is supported by recent studies showing that intracerebroventricular injections of NPY reduce alcohol intake in both alcohol preferring (P) and high alcohol drinking rats. NPY drug alcohol 15567472 However, it is unknown which anatomical NPY systems are involved in alcohol preference. NPY drug alcohol 15567472 This study was designed to investigate whether there are innate differences in NPY mRNA in cerebral cortical areas, dentate gyrus (DG) of the hippocampus and medial habenular nucleus (MHb) between P and alcohol nonpreferring (NP) rats, as these discrete brain regions are rich in NPY mRNA.

NPY drug alcohol 15337375 Evidence suggesting possible mechanism(s) by which NPY signaling modulates ethanol consumption are considered. NPY drug alcohol 15337375 It is suggested that NPY may influence ethanol consumption by regulating basal levels of anxiety, by modulating the sedative effects of ethanol, and/or by modulating ethanol's rewarding properties. NPY drug alcohol 15203244 Assessment of ethanol consumption and water drinking by NPY Y(2) receptor knockout mice. NPY drug alcohol 15203244 In recent years, pharmacological and genetic evidence have emerged suggesting that neuropeptide Y (NPY) and the NPY Y(1) receptor are involved with neurobiological responses to ethanol. NPY drug alcohol 15203244 In recent years, pharmacological and genetic evidence have emerged suggesting that neuropeptide Y (NPY) and the NPY Y(1) receptor are involved with neurobiological responses to ethanol. NPY drug alcohol 15203244 Pharmacological data implicate a role for the NPY Y(2) receptor in ethanol self administration. NPY drug alcohol 15203244 Here, we report that mutant mice lacking the NPY Y(2) receptor (Y(2)( / )), when maintained on a mixed 50% 129/ SvJ x 50 % Balb/cJ background, drink significantly less of solutions containing 3 or 6% (v/v) ethanol relative to wild type (Y(2)(+/+)) mice. NPY drug alcohol 15203244 However, Y(2)( / ) mice that are backcrossed to a Balb/cJ background show normal consumption of ethanol, indicating that the contributions of the NPY Y(2) receptor to ethanol consumption are genetic background dependent. NPY drug alcohol 15203244 The present results suggest roles for the NPY Y(2) receptor in the modulation of ethanol and water consumption. NPY drug alcohol 15182714 Here we show that allelic variation that alters the functional level of NPR 1, a neuropeptide Y (NPY) receptor like protein, can account for natural variation in the acute response to ethanol in wild strains of Caenorhabditis elegans. NPY drug alcohol 15182714 Here we show that allelic variation that alters the functional level of NPR 1, a neuropeptide Y (NPY) receptor like protein, can account for natural variation in the acute response to ethanol in wild strains of Caenorhabditis elegans. NPY drug alcohol 15182714 This suggests an explanation for the conserved function of NPY related pathways in ethanol responses across diverse species. NPY drug alcohol 15163695 It was also found that CREB deficient (+/ ) mice displayed more anxiety like behaviors and that acute ethanol exposure produced anxiolytic effects and significantly increased protein levels of p CREB and NPY in the central and medial but not in the basolateral amygdala of wild type mice, but these effects are attenuated in CREB deficient mice compared with wild type mice. NPY drug alcohol 15163695 Furthermore, alcohol drinking and anxiety like behaviors in CREB haplodeficient mice may possibly be related to decreased expression of NPY and BDNF in the brains of these mice.

NPY drug alcohol 11875632 These data suggest that NPY administration into the third ventricle preferentially regulates feeding compared to ethanol or sucrose drinking. NPY drug alcohol 11875632 In addition, since NPY significantly altered the cortical EEG in the absence of effects on ethanol and sucrose consumption, these data may indicate that NPY's cortical EEG effects are more related to its sedative or anxiolytic properties, rather than any effect on consumption. NPY drug opioid 11730241 Within the hypothalamus, decreased activity of both the dynorphin (kappa opioid) and neuropeptide Y systems occurs in aging rodents. NPY drug alcohol 11707630 Differential expression of NPY and its receptors in alcohol preferring AA and alcohol avoiding ANA rats. NPY drug alcohol 11707630 Recently, it has been suggested that NPY also has a role in regulation of alcohol consumption. NPY drug alcohol 11707630 NPY and NPY receptor expression in genetically selected alcohol preferring (AA), alcohol nonpreferring (ANA), and Wistar rats were investigated.

NPY addiction reward 11707630 NPY injected intracerebroventricularly (1.5 3.0 nmol) did not affect operant ethanol self administration in any of the three lines examined. NPY drug alcohol 11707630 The NPY system seems to differ in several respects between rat lines with different levels of alcohol preference. NPY drug alcohol 11707630 Differences observed within the hippocampus could be related to behavioral traits other than alcohol intake but it is also possible that elevated hippocampal expression of NPY in the ANA rats contributes to the low alcohol intake of this line. NPY drug alcohol 11707630 Aberrant NPY expression and/function within the amygdala complex could contribute to alcohol preference and constitute an anatomic substrate of the effects of NPY expression on alcohol intake observed previously in genetically modified animals.

NPY addiction withdrawal 11340648 The present study confirmed the inhibitory effect of NPY on withdrawal behavior.

NPY drug alcohol 11287109 Neuropeptide Y in the paraventricular nucleus increases ethanol self administration. NPY drug alcohol 11287109 The role of NPY in the PVN on ethanol self administration is unknown. NPY drug alcohol 11287109 Microinjections of NPY and NPY antagonists in the PVN were conducted prior to ethanol self administration sessions. NPY drug alcohol 11287109 All doses of NPY significantly increased ethanol self administration and preference, and decreased water intake. NPY drug alcohol 11287109 The NPY antagonist D NPY partially reduced ethanol self administration and completely blocked the effects of an intermediate dose of NPY (10 fmol) on ethanol intake, preference, and water intake. NPY drug alcohol 11287109 The competitive non peptide Y1 receptor antagonist BIBP 3226 did not significantly alter ethanol self administration or water intake when administered alone in the PVN but it completely blocked the effect of NPY (10 fmol) on ethanol intake. NPY drug alcohol 11287109 NPY infused in the PVN had no effect on ethanol self administration when tested in rats that did not have a long history of ethanol self administration. NPY drug alcohol 11287109 The doses of NPY tested produced no effect on food intake or body weight measured during the 24 h period after infusion in either ethanol experienced or ethanol inexperienced rats. NPY drug alcohol 11287109 These results indicate that elevation of NPY levels in the PVN potently increases ethanol self administration and that this effect is mediated through NPY Y1 receptors.

NPY addiction reward 11035216 To clarify the role of NPY in mediating reward processes and the possible interaction between reward and feeding, the present study examined the effects of injecting NPY bilaterally into the perifornical hypothalamus (PFH) vs. the nucleus accumbens (NAC) on intake of preferred vs. non preferred food types, as well as on conditioned place preference (CPP) learning. NPY addiction reward 11035216 A CPP that was negatively correlated with food intake occurred with the low (24 pmol/side) dose of NPY in the PFH, while a CPP that was not correlated with food intake was produced with the same dose in the NAC. NPY drug amphetamine 11035216 The extent of the CPPs produced by NPY injection in both brain sites mirrored that produced by peripheral injection of amphetamine (2.5 mg/kg). NPY addiction reward 11035216 These results indicate that NPY elicits reward related behavior, but not feeding, from the NAC, and both behaviors from the PFH. NPY drug opioid 10818386 Neuropeptides mainly involved in the control of GnRH release are opioids, neuropeptide Y (NPY), galanin, and corticotropin releasing factor (CRF), whereas neurotransmitters are noradrenaline, dopamine, serotonin, melatonin and gamma aminobutyric acid (GABA).

NPY drug amphetamine 10760371 Inhibition of amphetamine and apomorphine induced behavioural effects by neuropeptide Y Y(1) receptor antagonist BIBO 3304. NPY drug amphetamine 10760371 These data demonstrate that behavioural response to indirectly (amphetamine) and directly (apomorphine) acting dopaminergic stimulants is inhibited by NPY Y(1) receptor antagonists and suggest that NPY Y(1) receptor activation might be important in pathophysiology of disorders associated with hyperactivity of dopaminergic pathways, such as psychosis, schizophrenia and drug abuse. NPY drug amphetamine 10760371 We propose that the effects of BIBO 3304 on amphetamine/apomorphine induced locomotion and apomorphine induced aggressiveness are due to modulation of postsynaptic dopaminergic responses rather than direct effects of NPY Y(1) receptor antagonists on dopamine or NPY release. NPY drug alcohol 10627090 Genetic studies, including association and genome wide survey studies in both humans and rodents, implicate serotonin 1b receptor, dopamine D2 receptor, tryptophan hydroxylase and neuropeptide Y as candidate targets of genetic susceptibility in these pharmacodynamic actions of ethanol.

NPY drug opioid 10495011 The present study evaluated the effects of NPY on the discriminative stimulus and antinociceptive effects produced by the prototypical mu opioid, morphine. NPY drug opioid 10495011 Across a range of doses (3.0, 5.0, and 10 microg), intracerebroventricular (ICV) injection of NPY failed to substitute for, antagonize, or potentiate the discriminative stimulus effects of morphine.

NPY addiction withdrawal 10495011 A warm water tail withdrawal procedure was used to examine the antinociceptive effects of morphine and NPY, alone and in combination. NPY drug opioid 10495011 NPY (3.0 and 10 microg, ICV) failed to alter tail withdrawal latencies from 52 degrees and 56 degrees C water, whereas morphine (1.0 30 mg/kg, IP) produced a dose related increase in latencies at both water temperatures.

NPY drug alcohol 10414603 This enhanced sensitivity to CRF and NPY following chronic ethanol exposure and abstinence suggests that these peptidergic systems may play a role in the symptomatology of the prolonged abstinence syndrome. NPY drug alcohol 10397286 Innate differences of neuropeptide Y (NPY) in hypothalamic nuclei and central nucleus of the amygdala between selectively bred rats with high and low alcohol preference. NPY drug alcohol 10397286 Innate differences of neuropeptide Y (NPY) in hypothalamic nuclei and central nucleus of the amygdala between selectively bred rats with high and low alcohol preference. NPY drug alcohol 10397286 To examine the hypothesis that NPY might play a role in alcohol seeking behavior, this study took advantage of the genetic differences of the alcohol preferring (P) rats and alcohol nonpreferring (NP) rats, as well as the high alcohol drinking (HAD) rats and low alcohol drinking (LAD) rats, in voluntary alcohol consumption to examine if NPY neurons in the brains differ between these selected lines. NPY addiction relapse 10397286 To examine the hypothesis that NPY might play a role in alcohol seeking behavior, this study took advantage of the genetic differences of the alcohol preferring (P) rats and alcohol nonpreferring (NP) rats, as well as the high alcohol drinking (HAD) rats and low alcohol drinking (LAD) rats, in voluntary alcohol consumption to examine if NPY neurons in the brains differ between these selected lines. NPY drug alcohol 10397286 Therefore, the data indicate that there are innate differences in the NPY I in the brain between selectively bred rats with high and low alcohol preference. NPY drug alcohol 10397286 Because both P rats and HAD rats have high alcohol preference, the disparate finding between these two lines of rats suggests that the hypothalamic NPY neurons are probably not associated with alcohol preference. NPY drug alcohol 10397286 In contrast, consistent findings in the CeA of both P rats and HAD rats suggest that NPY in the CeA of P and HAD rats may contribute to the regulation of alcohol consumption. NPY drug alcohol 10397286 This is substantiated by a recent report showing that NPY knockout mice drink significantly more ethanol, and transgenic mice that overexpress the NPY gene drink less alcohol, than wild type mice. NPY drug alcohol 10397286 Together, the findings support the notion that NPY agonists that would enhance NPY function in the amygdala might be useful for the treatment of anxiety and alcoholism. NPY drug alcohol 9835294 Neuropeptide Y levels in ethanol naive alcohol preferring and nonpreferring rats and in Wistar rats after ethanol exposure. NPY drug alcohol 9835294 However, the effects of alcohol consumption/deprivation on NPY levels remain unknown. NPY drug alcohol 9835294 The present study sought to determine if brain NPY levels were affected by either alcohol exposure and/or correlated with genetic differences in preference for drinking alcohol. NPY drug alcohol 9835294 In the first experiment, NPY like immunoreactivity (NPY LI) was compared in alcohol naive, alcohol preferring (P), and nonpreferring (NP) rats. NPY drug alcohol 9835294 At 7 weeks of alcohol exposure, no significant changes in NPY LI in were found.

NPY addiction withdrawal 9835294 At 1 month after ethanol withdrawal, however, the ethanol exposed animals had significantly higher NPY LI in the hypothalamus (F = 4.78, p < 0.04) when compared with the nonexposed controls. NPY drug alcohol 9835294 Taken together, these studies suggest that exposure to chronic ethanol may affect NPY LI at the level of the hypothalamus in a fashion similar to food restriction, because 4 weeks after alcohol withdrawal, significantly higher NPY levels are found. NPY addiction withdrawal 9835294 Taken together, these studies suggest that exposure to chronic ethanol may affect NPY LI at the level of the hypothalamus in a fashion similar to food restriction, because 4 weeks after alcohol withdrawal, significantly higher NPY levels are found. NPY drug alcohol 9835294 In addition, differences in NPY LI in limbic areas and frontal cortex between alcohol naive P and NP rats suggest that NPY may also play a role in risk for the development of alcohol preference either by modulating the "tension reduction" properties of alcohol or by influencing consummatory behaviors.

NPY drug opioid 8853202 Following training, rats were injected with NPY (intraventricular, 5 micrograms) and various doses of naloxone (subcutaneous, 0, 0.1, 0.3, 1, 3, and 10 mg/kg). NPY drug opioid 8853202 NPY significantly increased the number of pellets consumed during the one hour session and naloxone (1, 3, and 10 mg/kg) blocked this effect. NPY drug opioid 8853202 Naloxone (3 and 10 mg/kg) increased the latency to the first response and blocked NPY's effect on completion of the first ratio. NPY drug opioid 8853202 NPY increased food intake during the 1 h session and naloxone blocked this effect. NPY drug opioid 8853202 NPY decreased the latency to eat, but naloxone failed to significantly antagonize this effect. NPY drug opioid 8853202 The amount of time spent eating was greater in the NPY group compared to the saline group and naloxone antagonized this effect. NPY drug opioid 8853202 Lag sequential analysis indicated that NPY induced a move eat move behavioral sequence that disappeared following naloxone administration. NPY drug opioid 8853202 These data lend support to the notion that opioids are involved in maintenance of NPY induced feeding but affect meal initiation in a minor way. NPY drug opioid 8853202 Only relatively high doses of naloxone (3 and 10 mg/kg) altered NPY induced changes in meal initiation.

NPY drug nicotine 7702541 Nicotine induced noradrenaline release was accompanied by neuropeptide Y overflow. NPY drug nicotine 7702541 When added 10 min after the onset of energy depletion, nicotine (10 mumol/l) caused a brief but marked enhancement of exocytotic noradrenaline release, since this release was calcium dependent and was accompanied by a significant rise of neuropeptide Y overflow. NPY drug nicotine 7702541 In absence of extracellular calcium to avoid exocytosis, concomitant administration of nicotine (3 100 mumol/l) and cyanide caused a concentration dependent acceleration of both the overflow of noradrenaline and DOPEG, whereas overflow of neuropeptide Y was not increased, thus indicating a nonexocytotic release mechanism.

NPY drug nicotine 3184776 Nicotine induced release of noradrenaline and neuropeptide Y in guinea pig heart. NPY drug nicotine 3184776 The effect of nicotine on the release of noradrenaline and neuropeptide Y was investigated in isolated perfused guinea pig hearts (Langendorff technique). NPY drug nicotine 3184776 Endogenous noradrenaline, dihydroxyphenylglycol (both determined by high pressure liquid chromatography) and neuropeptide Y (determined by radioimmunoassay) were measured in the coronary venous effluent following the addition of nicotine to the perfusate. NPY drug nicotine 3184776 Nicotine (2 microM to 2 mM) dose dependently increased both noradrenaline and neuropeptide Y overflow, and the release of both transmitters was closely correlated (r = 0.81). NPY drug nicotine 3184776 Despite ongoing nicotine administration noradrenaline and neuropeptide Y levels returned to basal values within 6 min of continuous nicotine administration indicating rapid tachyphylaxis to the effect of nicotine. NPY drug nicotine 3184776 The nicotine induced release of noradrenaline and neuropeptide Y required the presence of extracellular calcium, and the release of both substances was suppressed by hexamethonium or by low concentrations of the inhibitors of the neuronal noradrenaline uptake (uptake1) desipramine and nisoxetine. NPY drug nicotine 3184776 The close correlation between noradrenaline and neuropeptide Y release, its calcium dependence, and the lack of dihydroxyphenylglycol overflow are in agreement with the concept of a common and exocytotic release of noradrenaline and neuropeptide Y induced by nicotine.

GRM5 drug alcohol 28884874 Converging preclinical evidence links extrastriatal dopamine release and glutamatergic transmission via the metabotropic glutamate receptor 5 (mGluR5) to the rewarding properties of alcohol. GRM5 drug alcohol 28884874 Mesocorticolimbic dopamine release upon intravenous alcohol administration and mGluR5 availability were measured in 11 moderate social drinkers by single session [18 F]fallypride and [18 F]FPEB positron emission tomography, respectively. GRM5 drug alcohol 28884874 In contrast, baseline mGluR5 availability was positively correlated with the 'high' effect of alcohol in dorsolateral, ventrolateral and ventromedial PFCs and in the medial temporal lobe, thalamus and caudate nucleus (P < 0.05). GRM5 drug alcohol 28884874 Specifically, prefrontal dopamine release may encode alcohol 'liking' and 'wanting' effects in specific areas underlying value processing and motivation, whereas mGluR5 availability in distinct prefrontal temporal subcortical regions is more related to the alcohol 'high' effect. GRM5 drug alcohol 28884167 As the role for mGlu5 in anxiety is well established, we hypothesized that the reduced immobility exhibited by alcohol withdrawn mice when tested in the FST might reflect anxiety, possibly a hyper reactivity to the acute swim stressor.

GRM5 drug cocaine 25829143 Cocaine Decreases Metabotropic Glutamate Receptor mGluR1 Currents in Dopamine Neurons by Activating mGluR5. GRM5 drug cocaine 25829143 A single injection of cocaine decreased the current activated by mGluR1 in dopamine neurons, and it had no effect on the size of the mGluR5 mediated current. GRM5 drug cocaine 25829143 When the injection of cocaine was preceded by treatment of the animals with a blocker of mGluR5 receptors (MPEP), cocaine no longer decreased the mGluR1 current.

GRM5 drug nicotine 21896278 This lack of effect of 40 μg/0.5 μl/side MPEP on either nicotine or food self administration when administered into the VTA may be attributable either to actions of MPEP at presynaptic mGlu5 receptors or at targets other than mGlu5 receptors.

GRM5 addiction relapse 21790902 The data show that although mGluR2/3 and mGluR5 are differentially located on synaptic compartments, both LY379268 and MTEP produced the same behavioral effects in reducing stress induced reinstatement. GRM5 addiction relapse 21790902 These results are important because they demonstrate that a reduction in glutamate mediated neural excitability (albeit via different mechanisms of action) reverses footshock induced reinstatement and suggest that pharmacological manipulations of mGluR2/3 and mGluR5 can prevent the effects of stress, a major precipitating factor for relapse. GRM5 addiction relapse 21790902 These findings further confirm that mGluR2/3 or mGluR5 are promising targets for relapse prevention.

GRM5 drug alcohol 19641121 Interoceptive effects of alcohol require mGlu5 receptor activity in the nucleus accumbens. GRM5 drug alcohol 19641121 We found that systemic antagonism of metabotropic glutamate subtype 5 (mGlu5) receptors [10 mg/kg 2 methyl 6 (phenylethynyl)pyridine (MPEP) and 3 mg/kg 3 ((2 methyl 1,3 thiazol 4 yl)ethynyl)pyridine], but not mGlu1 receptors ([0.3 3 mg/kg JNJ16259685) (3,4 dihydro 2H pyrano[2,3]beta quinolin 7 yl)(cis 4 methoxycyclohexyl) methanone)], inhibited the discriminative stimulus effects of alcohol.

GRM5 addiction relapse 18400131 The metabotropic glutamate receptor 5 (mGlu5) has been implicated in ethanol and drug seeking behaviours in rodent studies. GRM5 drug alcohol 18400131 Here we examine a number of ethanol related behavioural assays in mice lacking mGlu5 and wild type littermates.

GRM5 drug alcohol 18377703 Lack of mGluR5 or administration of MPEP reduced the severity of alcohol induced withdrawal (AW), increased the sedative effect of alcohol (duration of loss of righting reflex; LORR), and increased basal motor activity. GRM5 addiction withdrawal 18377703 Lack of mGluR5 or administration of MPEP reduced the severity of alcohol induced withdrawal (AW), increased the sedative effect of alcohol (duration of loss of righting reflex; LORR), and increased basal motor activity. GRM5 drug alcohol 18377703 The motor stimulation produced by ethanol was blocked by deletion of mGluR5, but not by injection of MPEP. GRM5 drug alcohol 18377703 No effects of acamprosate or MPEP on ethanol induced LORR and AW were found in mGluR5 knockout mice, demonstrating that mGluR5 is required for these actions. GRM5 drug alcohol 18377703 mGluR5 null mutant mice showed decreased alcohol consumption in some, but not all, tests. GRM5 drug alcohol 18377703 These data show the importance of mGluR5 for several actions of alcohol and support the hypothesis that some effects of acamprosate require mGluR5 signalling.

GRM5 drug amphetamine 17693584 However, it is not known whether RGS4 and mGluR5 interactions occur in rat striatum and whether chronic amphetamine (AMPH) treatment produces changes in RGS4 levels that are correlated with mGluR5 receptor activity. GRM5 drug amphetamine 17693584 In contrast, total levels of mGluR5 receptors in the striatum were not altered by any AMPH treatment. GRM5 drug amphetamine 17693584 This study further suggests that AMPH induced changes in mGluR5 associated protein levels (RGS4, Galpha(q/11), and PLCbeta1) may be related to altered coupling of striatal mGluR5 receptors in animals sensitized to AMPH.

HTR2A drug opioid 32458577 ), blocked the effects of DOI, indicating that DOI is acting through 5 HT2A receptors to alter economic demand for fentanyl. HTR2A drug opioid 32458577 These results demonstrate that both intermittent and continuous fentanyl experience raise the economic demand for fentanyl, and acute 5 HT2A receptor activation reduces economic demand for fentanyl and food. HTR2A drug psychedelics 32371500 The mind altering qualities of psychedelics have been attributed, through serotonin 2A (5 HT2A) receptor agonism, to 'reset' areas of functional connectivity (FC) in the brain that play prominent roles in many central neuropathic states. HTR2A drug psychedelics 32371500 While the mechanisms by which the classic psychedelics may provide analgesia are not clear, several possibilities exist given the similarity between 5 HT2A activation pathways of psychedelics and the nociceptive modulation pathways in humans.

HTR2A drug opioid 32199997 Adenosine A1 receptor agonist induces visceral antinociception via 5 HT1A, 5 HT2A, dopamine D1 or cannabinoid CB1 receptors, and the opioid system in the central nervous system. HTR2A drug opioid 32199997 These results suggest that 5 HT1A, 5 HT2A, dopamine D1, CB1 receptors and the opioid system in the CNS may specifically mediate the CPA induced visceral antinociception. HTR2A drug psychedelics 32128596 The behavioural experiments are mainly related with the hallucinogenic effect of 25I NBOMe while the in vitro studies concerning mainly the affinity for 5 HT2A receptors.

HTR2A drug alcohol 31954952 Evidence suggests that aripiprazole, a partial dopamine D2 and serotonin 5 HT1A receptor agonist and 5 HT2A receptor antagonist, show significant efficacy in reducing alcohol use. HTR2A drug psychedelics 31915427 25I NBOMe acts as full agonist on serotonergic 5 HT2A receptors. HTR2A drug psychedelics 31829932 We will show that although ketamine and serotonergic psychedelics have affinity for very different receptors (NMDA, 5 HT2A), they ultimately initiate similar plastic adaptations in the prefrontal cortex through the involvement of the brain derived neurotrophic factor (BDNF).

HTR2A addiction relapse 30738094 When the risk of relapse was analyzed one month after the end of treatment, regardless of the age of onset, the T allele (rs6313) of HTR2A appeared to be a risk factor for relapse (OR = 2.92, 95% CI = 1.06 8.11); the T allele was found more frequently in those who relapsed (50.0%) compared with people who maintained abstinence (25.4%) (p = 0.0332). HTR2A drug nicotine 30738094 Our findings suggest that in Mexican mestizos who smoke cigarettes, the presence of the T allele in rs6313 of the HTR2A gene increases the risk for the early onset of cigarette smoking as well as the risk for relapsing one month after completing smoking cessation treatment. HTR2A drug psychedelics 30629611 In the binding (radioligand displacement) studies some of these compounds exhibited only modest selectivity for either 5 HT2A or 5 HT2C receptors suggesting that a few of them, with affinities in the 10 100 nanomolar range for 5 HT2A receptors, might presumably be psychedelic. HTR2A drug psychedelics 30628811 The prototype 5 HT2A receptor agonist hallucinogens LSD, mescaline, and psilocybin are classified as Schedule 1 drugs of abuse by the U.S. Drug Enforcement Administration. HTR2A drug psychedelics 30628811 These results extend those of previous preclinical studies to suggest weak expression of abuse related effects by 5 HT2A agonist hallucinogens and provide supportive evidence for therapeutic effects of repeated LSD dosing to attenuate KOR mediated depressant effects but not abuse potential of psychostimulants. HTR2A addiction reward 30469095 However, the role of 5 HT2A receptors on the reinforcing effects of psychostimulant drugs has not been fully elucidated. HTR2A drug amphetamine 30469095 In the present study, we investigated the effects of the selective 5HT2A receptor antagonist M100907 alone or in combination with the selective 5HT2C agonist WAY 163909 on intravenous methamphetamine self administration in rhesus macaques (N = 3). HTR2A drug amphetamine 30469095 Our study indicates that acute selective 5 HT2A receptor blockade decreases peak methamphetamine intake in nonhuman primates.

HTR2A addiction relapse 30373886 The investigational serotonin (5 HT) 5 HT2A receptor (5 HT2AR) antagonist/inverse agonist M100907 suppresses impulsive action, or the inability to withhold premature responses, and cocaine seeking behaviors. HTR2A drug psychedelics 30318013 Its pharmacodynamic mechanisms of action are primarily attributed to the interaction with the serotonergic 5 HT2A C receptors, and therefore clinical effects are similar to those elicited by other psychoactive substances, such as lysergic acid diethylamide (LSD) and psilocybin, which include euphoria, hallucinations, depersonalization and psychoses. HTR2A drug psychedelics 30261175 25D NBOMe, 25E NBOMe, 25H NBOMe, 25I NBOH and 25N NBOMe had very high affinity for, and full efficacy at, 5 HT2A and 5 HT2C receptors. HTR2A drug psychedelics 30261175 In the 5 HT2A receptor functional assay, 25D NBOMe, 25E NBOMe, 25I NBOH and 25N NBOMe had subnanomolar to low nanomolar potencies similar to (+)lysergic acid diethylamide (LSD) while 25H NBOMe had lower potency, similar to serotonin. HTR2A drug amphetamine 30240581 Chronic methamphetamine self administration dysregulates 5 HT2A and mGlu2 receptor expression in the rat prefrontal and perirhinal cortex: Comparison to chronic phencyclidine and MK 801. HTR2A drug amphetamine 30240581 Therefore, in the present study we examined the effects of chronic exposure to three different drugs known to produce persistent deficits in sensorimotor gating and cognition [meth, phencyclidine (PCP) and MK 801] on the expression of 5 HT2A and mGlu2 within the rat medial prefrontal cortex (mPFC), dorsal hippocampus (dHPC) and perirhinal cortex (PRh). HTR2A drug amphetamine 30240581 We found that despite different pharmacological mechanism of action, chronic meth, PCP, and MK 801 similarly dysregulated 5 HT2A and mGlu2, as indicated by an increase in the 5 HT2A/mGlu2 expression ratio in the mPFC (all three tested drugs), PRh (meth and PCP), and dHPC (MK 801 only). HTR2A drug amphetamine 30240581 In summary, these data suggest that a shift towards increased availability (and G protein coupling) of cortical 5 HT2A vs. mGlu2 receptors may represent a common neurobiological mechanism underlying the emergence of psychosis and cognitive deficits observed in subjects with meth use disorder and schizophrenia.

HTR2A addiction sensitization 17510759 Paradoxical constitutive behavioral sensitization to amphetamine in mice lacking 5 HT2A receptors. HTR2A drug amphetamine 17510759 Although locomotor response to d amphetamine is considered as mediated by an increased release of dopamine in the ventral striatum, blockade of either alpha1b adrenergic or 5 HT2A receptors almost completely inhibits d amphetamine induced locomotor response in mice. HTR2A drug amphetamine 17510759 However, we show here that, paradoxically, mice lacking 5 HT2A receptors (5 HT2A R KO) exhibit a twofold higher locomotor response to d amphetamine than wild type (WT) littermates. HTR2A drug amphetamine 17510759 Locomotor response and behavioral sensitization to d amphetamine were measured in presence of prazosin and/or SR46349B, alpha1b adrenergic, and 5 HT2A receptor antagonists, respectively.

HTR2A drug amphetamine 17510759 One milligrams per kilogram of prazosin completely blocks d amphetamine induced locomotor response in 5 HT2A R KO naïve animals but 3 mg/kg is necessary in sensitized 5 HT2A R KO mice. HTR2A drug amphetamine 17510759 Because naïve 5 HT2A R KO mice exhibit an increased cortical noradrenergic response to d amphetamine, our data suggest that repeated d amphetamine modifies noradrenergic transmission in 5 HT2A R KO mice. HTR2A drug amphetamine 17510759 Dramatic decrease in SR46349B efficiency in sensitized WT mice indicates that a disruption of the regulating role of 5 HT2A receptors on noradrenergic transmission occurs during sensitization and thus represents the physiological basis of behavioral sensitization to d amphetamine. HTR2A addiction sensitization 17510759 Dramatic decrease in SR46349B efficiency in sensitized WT mice indicates that a disruption of the regulating role of 5 HT2A receptors on noradrenergic transmission occurs during sensitization and thus represents the physiological basis of behavioral sensitization to d amphetamine.

HTR2A addiction withdrawal 17259860 Withdrawal from a single exposure to cocaine increases 5 HT2A receptor and G protein function. HTR2A addiction addiction 17102981 The selective serotonin (5 HT) reuptake inhibitors (SSRIs) represent the first line pharmacotherapy for obsessive compulsive disorder (OCD), and atypical antipsychotic drugs, which block 5 HT2A receptors, are used in augmentation strategies. HTR2A addiction addiction 17102981 The 5 HT2A related behavior (i.e., head twitch) has been related with tics, stereotypes, and compulsive symptoms observed in Tourette syndrome and OCD. HTR2A drug opioid 17102981 Combined 5 HT and opioid properties result in a greater efficacy in antagonizing 5 HT2A related behavior.

HTR2A addiction withdrawal 17055657 Cocaine mediated supersensitivity of 5 HT2A receptors in hypothalamic paraventricular nucleus is a withdrawal induced phenomenon. HTR2A drug cocaine 17055657 We previously reported that treatment and withdrawal from cocaine increases: (1) 5 HT2A receptor mediated neuroendocrine responses, and (2) Galphaq and Galpha11 G protein levels in the hypothalamic paraventricular nucleus (PVN) at 48 h post treatment.

HTR2A addiction withdrawal 17055657 This study investigates changes in the initial 24 h of withdrawal to discern whether 5 HT2A receptor supersensitivity is due to cocaine treatment or is induced during the withdrawal period. HTR2A addiction withdrawal 17055657 We report here increases in 5 HT2A receptor mediated neuroendocrine responses only 12 or 24 h post treatment, but not during the initial 4 h withdrawal period. HTR2A drug cocaine 17055657 However, the density of 125I ( ) 1 (2,5 dimethoxy 4 iodophenyl) 2 amino propane HCl (DOI) labeled high affinity 5 HT2A receptors in PVN increased 35% in rats withdrawn from cocaine for 24 h. These findings demonstrate that cocaine induced increases in 5 HT2A receptor function in PVN represents a withdrawal induced phenomena that: (1) is likely attributed to increased G protein coupled/high affinity conformational state of the 5 HT2A receptor, and (2) occurs in the absence of changes in the levels of associated G proteins during the first 24 h.

HTR2A drug amphetamine 17051415 Effects of d amphetamine and DOI (2,5 dimethoxy 4 iodoamphetamine) on timing behavior: interaction between D1 and 5 HT2A receptors. HTR2A addiction dependence 17017968 Serotonin 5 HT2A and 5 HT2C receptors as potential targets for modulation of psychostimulant use and dependence. HTR2A drug cocaine 17017968 Two key modulators of DA output are the serotonin (5 HT)2A receptor (5 HT2A R) and the 5 HT2C R. These receptors are known to control the neurochemical and behavioral effects of psychostimulants, and in particular, the in vivo effects of cocaine. HTR2A drug cocaine 17017968 Preclinical studies indicate that 5 HT2A R antagonists and/or 5 HT2C R agonists may effectively reduce craving and/or relapse, and likewise, enhance abstinence, while 5 HT2C R agonists may also effectively reduce cocaine intake in active cocaine users. HTR2A addiction relapse 17017968 Preclinical studies indicate that 5 HT2A R antagonists and/or 5 HT2C R agonists may effectively reduce craving and/or relapse, and likewise, enhance abstinence, while 5 HT2C R agonists may also effectively reduce cocaine intake in active cocaine users. HTR2A drug cocaine 17017968 At present, the progression of studies to probe the effectiveness of 5 HT2A R and 5 HT2C R ligands in the clinical setting is hindered by a lack of available selective 5 HT2A R antagonists or 5 HT2C R agonists for use in human cocaine abusers. HTR2A drug amphetamine 16326032 Systemic treatment with the 5 HT(2A/2C) receptor agonist 2,5, dimethoxy 4 iodo amphetamine (DOI) (0.25 mg/kg, s.c.) reduced T50; the 5 HT2A receptor antagonist MDL 100907 (0.5 mg/kg, i.p.)

HTR2A drug psychedelics 16005500 When LSD [0.17 mg/kg] was administered in combination with the selective 5 HT2A antagonist, M100907, LSD appropriate responding was significantly but incompletely reduced to approximately 50%; concurrently, response rates declined significantly. HTR2A drug benzodiazepine 15918077 The drugs studied were two BZDs, diazepam (1 mg/kg) and alprazolam (0.25 mg/kg); flumazenil, a GABA(A) receptor antagonist (8 mg/kg); atropine sulphate, a muscarinic cholinergic receptor antagonist (4 mg/kg) known for its amnesic properties; paroxetine, a selective serotonin reuptake inhibitor (4 and 8 mg/kg); venlafaxine, a serotonin and noradrenalin reuptake inhibitor (4 and 16 mg/kg); and DOI, a 5 HT2A agonist (1 mg/kg).

HTR2A drug opioid 15821952 These data give further evidence for: (a) the involvement of endogenous opioids and a mu1 opioid receptor in the sweet substance induced antinociception; (b) the involvement of monoamines and 5HT2A serotonergic/alpha1 noradrenergic receptors in the central regulation of the sweet substance produced analgesia. HTR2A drug psychedelics 15723230 LSD (186 or 372 nmol/kg, 0.08 or 0.16 mg/kg) given 30 min prior to training produced a cue that was completely antagonized by 5 HT2A antagonists and lasted no longer than 1 h. LSD (372 nmol/kg, 0.16 mg/kg) injected 90 min before training produced a cue that was not fully blocked by 5 HT2A antagonists, but instead was significantly inhibited by haloperidol. HTR2A drug nicotine 15682310 The current study served to determine the impact of a relatively selective 5 HT2A receptor antagonist, ketanserin, on attentional function in rats and the interactions of ketanserin with nicotine administration. HTR2A drug nicotine 15682310 These data suggest a functional interaction between nicotine and 5 HT2A receptor antagonist ketanserin. HTR2A addiction sensitization 15579162 5 HT2A and alpha1b adrenergic receptors entirely mediate dopamine release, locomotor response and behavioural sensitization to opiates and psychostimulants. HTR2A drug opioid 15579162 This acute morphine evoked DA release was completely blocked in alpha1b AR KO mice by SR46349B (1 mg/kg), a 5 HT2A antagonist. HTR2A drug amphetamine 15579162 Accordingly, the concomitant blockade of 5 HT2A and alpha1b adrenergic receptors in WT mice entirely blocked acute locomotor responses but also the development of behavioural sensitization to morphine, D amphetamine or cocaine (10 mg/kg).

HTR2A addiction sensitization 15579162 Accordingly, the concomitant blockade of 5 HT2A and alpha1b adrenergic receptors in WT mice entirely blocked acute locomotor responses but also the development of behavioural sensitization to morphine, D amphetamine or cocaine (10 mg/kg). HTR2A addiction sensitization 15579162 Because of these latter data and the possible compensation by 5 HT2A receptors for the genetic deletion of alpha1b adrenergic receptors, we postulate the existence of a functional link between these receptors, which vanishes during the development of behavioural sensitization.

HTR2A drug cocaine 14534355 Rats were sacrificed 2 or 7 days after the last cocaine injection, and the levels of membrane and cytosol associated 5 HT2A receptors, Galphaq, Galpha11, regulators of G protein signaling (RGS)4, and RGS7 proteins were assayed in the hypothalamic paraventricular nucleus, amygdala, and frontal cortex using Western blot analysis. HTR2A drug cocaine 14534355 The protein levels of the 5 HT2A receptor, Galphaz protein, and RGS4 or RGS7 proteins were not altered by cocaine withdrawal in any of the above mentioned brain regions. HTR2A addiction withdrawal 14534355 The protein levels of the 5 HT2A receptor, Galphaz protein, and RGS4 or RGS7 proteins were not altered by cocaine withdrawal in any of the above mentioned brain regions. HTR2A drug cocaine 14534355 These findings suggest that the supersensitivity of the 5 HT2A receptors, during withdrawal from chronic cocaine, is associated with an increase in membrane associated Galphaq and Galpha11 proteins and not with changes in the expression of 5 HT2A receptors.

HTR2A addiction dependence 12054060 In conclusion, the ability of selective 5 HT2A receptor antagonists to interfere with the heightened state of dopamine activity without altering basal tone, suggests that these drugs possess antipsychotic activity and may provide the basis for new therapies for psychosis and drug dependence, in addition to contributing towards a more complete understanding of 5 HT2A receptor function. HTR2A drug psychedelics 11705117 It appears that 5 HT2A, 5 HT2C, and sigma 2 receptors are involved in mediating the stimulus effects of ibogaine. HTR2A drug psychedelics 11705117 Ibogaine's hallucinogenic effects may be explained by its interactions with 5 HT2A and 5 HT2C receptors, while its putative antiaddictive properties may result from its interactions with sigma 2 and opiate receptors.

HTR2A drug alcohol 11287798 This is the first report about an association of 5 HT2A promoter polymorphism and impulsive behavior in alcohol dependents. HTR2A drug cocaine 11259563 Serotonin (5 hydroxytryptamine; 5 HT) 5 HT(2A) receptors have been shown to modulate dopamine (DA) function and a more thorough appreciation of this modulatory interaction between 5 HT2A receptors and DA systems may yield insight into novel approaches to treatment of cocaine dependence.

HTR2A drug cocaine 11259563 The present study examined the effects of two ligands with varying selectivity for 5 HT2A receptors on the locomotor stimulant and discriminative stimulus effects of cocaine in male rats. HTR2A drug cocaine 11259563 Locomotor activity was measured following intraperitoneal injection of vehicle (1 ml/kg), the selective 5 HT2A receptor antagonist M100907 [R (+) (2,3 dimethoxyphenyl) 1 [2 (4 fluorophenylethyl)] 4 piperidine methanol] (0.02 2.0 mg/kg), or the 5 HT(2) receptor antagonist ketanserin (0.04 4 mg/kg) 45 min before administration of saline (1 ml/kg) or cocaine (10 mg/kg); monitoring of activity in photobeam chambers began at once and proceeded for 1 h. Neither M100907 nor ketanserin significantly altered basal locomotor activity, but both drugs attenuated cocaine induced hyperactivity (p < 0.05). HTR2A drug cocaine 11259563 These results suggest that 5 HT2A receptors play an important role in the behavioral effects of cocaine and that 5 HT2A receptors should be considered a viable target for analysis in the search for pharmacotherapies useful in the treatment of cocaine dependence.

HTR2A drug psychedelics 9924841 Most psychedelic drugs are potent agonists at 5 HT2A and 5 HT2C receptors and their binding potency to these receptors is strongly correlated with their human potency as hallucinogens. HTR2A drug alcohol 9887443 It appears from the literature that PKC plays an important role in the modulation of the function of various neurotransmitter receptors (e.g., gamma aminobutyrate type A [GABAA], N methyl D aspartate [NMDA], serotonin2A [5 HT2A], and 5 HT2C, and muscarinic [m1] receptors) resulting from ethanol exposure.

HTR2A drug alcohol 9443541 Amperozide, a novel 5 HT2A receptor antagonist that releases dopamine from mesolimbic neurons suppresses alcohol drinking in rats. HTR2A drug alcohol 9443541 Further, the 10.0 mg/kg dose of amperozide given prior to the control saline gavage evoked a hyperthermic response in the rats that persisted for 5 h. These results suggest that the antagonism of 5 HT2A receptors on central serotonergic synapses involved in thermoregulation acts to counteract the potent thermolytic effects of alcohol at an ambient temperature that is below thermoneutrality. HTR2A drug benzodiazepine 9401775 The 5 HT2A/2B/2C receptor antagonists ritanserin, MDL11939 and RP62203 and also methysergide, which failed to modify mouse behaviour when administered alone, caused dose related enhancements (4 to 8 fold) in the potency of diazepam to disinhibit behavioural responding to the aversive situation of the test box.

HTR2A drug alcohol 9394117 These complex findings suggest that biochemical properties other than 5 HT2A receptor antagonism (e.g., 5 HT1A receptor agonism) may be involved in the effects of amperozide and FG 5974 on alcohol intake and other consummatory behaviors.

GRIA1 addiction reward 32717192 We then examined the expression of dopamine D2 receptor and GluA1 AMPA receptor and GluA2 AMPA receptor subunit expression in rats after acquisition of morphine induced CPP. GRIA1 drug opioid 32717192 We found that repeated administration of morphine produced a significant reduction in dopamine D2 receptor expression in the prefrontal cortex, hippocamps, and striatum, while an increase in the striatal GluA1 AMPA receptor expression. GRIA1 drug opioid 32717192 Pretreatment with corydaline or l THP blocked morphine induced dopamine D2 receptor down regulation and GluA1 AMPA receptor up regulation in these brain regions. GRIA1 drug alcohol 32599136 Brain area samples were analysed to quantify AMPAR subunits GluR1/2 and pCREB/CREB expression following alcohol self administration. GRIA1 drug alcohol 32599136 Our findings demonstrate that developmental alcohol exposure enhances alcohol intake during adolescence, which is associated with a decrease in the pCREB/CREB ratio in the hippocampus, prefrontal cortex and striatum, while the GluR1/GluR2 ratio showed a decrease in the hippocampus. GRIA1 drug cocaine 32522229 Here, we assess the role of homeostatic mechanisms in the neurobiology of cocaine addiction by providing a brief overview of the parallels between cocaine induced synaptic potentiation and long term synaptic adaptations, focusing on the regulation of GluA1 and GluN1 containing receptors.

GRIA1 addiction withdrawal 32450347 At hippocampal level, the withdrawal induced changes in the levels of AMPA receptor GluA1 and GluA2/3 subunits, PSD 95 protein, corticotropin releasing factor (Crf) and Crf receptor 1 (CrfR1) mRNA were biphasic: AMPA receptor subunit and PSD95 protein levels initially remained unchanged and decreased after 60 90 days, whereas Crf/CrfR1 mRNA levels initially increased and then markedly decreased after 60 days. GRIA1 drug cocaine 32329565 We also investigated the subsequent alterations on GluR2, GluR1, cAMP response element binding (CREB), and CREB phosphorylation (pCREB) in ventral tegmental area (VTA) and nucleus accumbens (NAc) induced by both MSEW and cocaine SA. GRIA1 drug alcohol 32062779 We aimed to investigate whether ethanol (EtOH) and acetaldehyde (AcH) can affect glutamate and its receptors GluN1 and GluA1 in the hippocampus of Aldh2 knockout (Aldh2 KO) and C57BL/6N (wild type (WT)) mice. GRIA1 addiction intoxication 32062779 Together, these in vivo and ex vivo data suggest that EtOH and AcH decrease extracellular glutamate in the hippocampus of mice with a concomitant decrease in GluN1 and GluA1 subunits, but these effects require relatively high concentrations and may, therefore, explain the consequences of EtOH intoxication. GRIA1 drug cocaine 31918976 Moreover, we evaluated the effects of cocaine SA in both sexes during adulthood, and the possible changes in GluA1, GluA2, pCREB and CREB expressions. GRIA1 drug cocaine 31905369 These findings outline an essential role for the interaction between D1R, Cav1.2, and GluA1 signaling in the dDG for extinction of cocaine associated contextual memories.

GRIA1 drug opioid 31863796 Microinjection of NASPM, a selective inhibitor of homomeric GluA1 AMPARs, into CeA inhibited morphine intake. GRIA1 drug opioid 31863796 Furthermore, viral overexpression of GluA1 protein in CeA maintained morphine intake at a higher level than controls and reversed the pain induced reduction in morphine intake. GRIA1 drug opioid 31863796 These findings suggest that CeA GluA1 promotes opioid use and its upregulation is sufficient to increase opioid consumption, which counteracts the acute inhibitory effect of pain on opioid intake. GRIA1 drug opioid 31863796 These results demonstrate that the CeA GluA1 is a shared target of opioid and pain in regulation of opioid use, which may aid in future development of therapeutic applications in opioid abuse.

GRIA1 drug opioid 31209728 Results showed that membrane expression of GluA1 and GluA2 in the vmPFC was decreased following the recent retrieval, while the membrane expression of GluA1 and GluA2 in the vmPFC was increased following the remote retrieval of morphine associated memory. GRIA1 drug cocaine 31146278 Previous biochemical studies revealed that the CP AMPARs accumulating after cocaine incubation are mainly homomeric GluA1 receptors and that their accumulation is reflected by increased cell surface GluA1. GRIA1 drug amphetamine 31146278 Here, for methamphetamine, we observed no significant change in surface or total GluA1 (GluA2 and GluA3 were also unchanged). GRIA1 drug amphetamine 31146278 Nonetheless, GluA1 translation was elevated after incubation of methamphetamine craving, as recently found for cocaine.

GRIA1 drug psychedelics 31128500 However, no changes in the p70S6K, PSD 95, GluA1, and synapsin immunocontents were found in the hippocampus of ketamine plus guanosine treated mice. GRIA1 drug opioid 30902386 Furthermore, KO mice showed more elevation in the phosphorylation of AMPA receptor GluR1 S845 than WT mice, while the total expression of GluR1 remained unchanged after morphine dependence. GRIA1 addiction dependence 30902386 Furthermore, KO mice showed more elevation in the phosphorylation of AMPA receptor GluR1 S845 than WT mice, while the total expression of GluR1 remained unchanged after morphine dependence. GRIA1 drug opioid 30902386 Altogether, these data suggest that IRAS may play an important role in the development of morphine tolerance and physical dependence in vivo through modulating MOR expression, as well as AMPA GluR1 S845 phosphorylation, which might be one of the mechanisms underlying the development of opiate addiction.

GRIA1 addiction withdrawal 30733663 We found that only GluA1 and mGluR5 expression levels were significantly increased after EtOH withdrawal and, in neuroprotection experiments, we observed that AMPA and mGluR5 antagonists attenuated EtOH withdrawal induced toxicity. GRIA1 drug cocaine 30498893 Here, we show that cocaine SA decreased PrL NA core spine head diameter, nuclear Fos IR and pCREB IR, and GluA1 IR and GluA2 IR in putative mushroom type spines 2 h after the end of cocaine SA, whereas the opposite occurred following 1 week of abstinence.

GRIA1 drug cannabinoid 30273593 In parallel, CBD increased expression of type 1 cannabinoid receptor, MAPK CREB phosphorylation, BDNF expression, and neural cell proliferation in the hippocampus, and reduced the GluA1/2 AMPA subunit receptor ratio in the striatum. GRIA1 drug cocaine 30144237 In cocaine naïve animals, SERT removal led to reduced baseline Hb mRNA levels of critical determinants of glutamate transmission, such as SLC1A2, the main glutamate transporter and N methyl D aspartate (Grin1, Grin2A and Grin2B) as well as α amino 3 hydroxy 5 methyl 4 isoxazolepropionic acid (Gria1 and Gria2) receptor subunits, with no changes in the scaffolding protein Dlg4. GRIA1 drug opioid 29754475 The results of this study show that the NAc specific knockdown of RGS4 significantly increased the behaviors associated with morphine and did so by phosphorylation of the GluR1 (Ser831) and NR2A (Tyr1325) glutamate receptors in the NAc. GRIA1 drug opioid 29754475 Furthermore, the knock down of RGS4 enhanced the phosphorylation of the GluR1 and NR2A glutamate receptors in the primary NAc/striatal neurons during spontaneous morphine withdrawal.

GRIA1 drug cocaine 29622268 We compared basal overall translation and its regulation by metabotropic glutamate receptor 1 (mGlu1), mGlu5, and N methyl D aspartate receptors (NMDARs) in drug naïve, saline control, and cocaine rats, and we compared GluA1 and GluA2 translation by immunoprecipitating puromycin labeled proteins. GRIA1 drug cocaine 29622268 Cocaine/late withdrawal rats exhibited greater translation of GluA1 (but not GluA2), which was not further affected by NMDAR blockade.

GRIA1 addiction relapse 29317777 This viral mediated attenuation of cocaine reinstatement was accompanied by decreased phosphorylation of GluA1 containing AMPARs and attenuated AMPAR eEPSCs. GRIA1 drug amphetamine 29247759 METH treated mice also showed i) decreased levels of total H3ac and H4ac, and increased levels of 5 mC, ii) decreased H3ac enrichment at promoters of Drd2, Hcrtr1/2, Hrh1 and Grin1, and increased H4ac enrichment at Drd1, Hrh1 and Grin1, iii) increased mRNA of Drd1a, Grin1 and Gria1. GRIA1 addiction relapse 29197981 A significant increase in AMPA receptor subunit GluA1 surface expression was also observed during estrus, potentially influencing reinstatement. GRIA1 addiction relapse 29197981 The effects of estrus on GluA1 expression and reinstatement observed here indicate that females may need additional interventions during some phases of the menstrual cycle. GRIA1 drug cocaine 29196318 Inactivation of NMDA Receptors in the Ventral Tegmental Area during Cocaine Self Administration Prevents GluA1 Upregulation but with Paradoxical Increases in Cocaine Seeking Behavior. GRIA1 addiction relapse 29196318 Inactivation of NMDA Receptors in the Ventral Tegmental Area during Cocaine Self Administration Prevents GluA1 Upregulation but with Paradoxical Increases in Cocaine Seeking Behavior. GRIA1 drug cocaine 29196318 Cocaine self administration increases expression of GluA1 subunits in ventral tegmental area (VTA) dopamine neurons, which subsequently enhance the motivation for cocaine. GRIA1 drug cocaine 29196318 This increase in GluA1 may be dependent on concomitant NMDA receptor (NMDAR) activation during self administration, similar to cocaine induced long term potentiation in the VTA. GRIA1 drug cocaine 29196318 In this study, we used viral mediated expression of a dominant negative GluN1 subunit (HSV dnGluN1) in VTA neurons to study the effect of transient NMDAR inactivation on the GluA1 increases induced by chronic cocaine self administration in male rats. GRIA1 drug cocaine 29196318 We found that dnGluN1 expression in the VTA limited to the 3 weeks of cocaine self administration prevents the subsequent increase in tissue GluA1 levels when compared with control infusions of HSV LacZ. GRIA1 drug cocaine 29196318 Despite blocking tissue GluA1 increases in cocaine self administering animals, the HSV dnGluN1 treatment resulted in increased membrane levels of GluA1 and GluN2B, along with markedly higher locomotor responses to intra VTA infusions of AMPA, suggesting a paradoxical increase in VTA AMPA receptor responsiveness. GRIA1 drug cocaine 29196318 Together, these data suggest that NMDARs mediate cocaine induced increases in VTA GluA1 expression, but such transient NMDAR inactivation also leads to compensatory scaling of synaptic AMPA receptors that enhance the motivational for cocaine.SIGNIFICANCE STATEMENT Dopamine neurons in the ventral tegmental area (VTA) are critical substrates of drug rewards. GRIA1 drug psychedelics 29158578 However, ketamine blunted the increase in the phosphorylation of the GluA1 subunit of AMPARs at a calcium/calmodulin dependent protein kinase II/protein kinase C site induced by an LTP induction protocol. GRIA1 drug psychedelics 29158578 Moreover, ketamine caused a persistent increased phosphorylation of GluA1 at a protein kinase A site. GRIA1 drug cocaine 29089442 Finally, conditional knock out of Cav1.2 in dopamine D1 receptor (D1R) expressing cells resulted in attenuation of cocaine CPP extinction and lack of extinction dependent changes in hippocampal PSD CaMKII expression and S831 GluA1 phosphorylation.

GRIA1 drug psychedelics 28948570 Since GluN2B, via inhibition of ERK, regulates the membrane expression of GluA1, we measured ERK2 phosphorylation in the crude synaptosomal fraction of these brain regions, which was significantly reduced suggesting that ketamine induced phosphorylation of αCaMKII promotes GluN2B (S1303) phosphorylation that, in turn, inhibits ERK 2 signaling, an effect that results in reduced membrane expression and phosphorylation of GluA1. GRIA1 drug psychedelics 28948570 Taken together, our findings point to αCaMKII autophosphorylation as a critical signature of ketamine self administration providing an intracellular mechanism to explain the different effects caused by αCaMKII autophosphorylation on the post synaptic GluN2B and GluA1 mediated functions. GRIA1 drug alcohol 28865912 Western blotting revealed a higher level of phosphorylated AMPAR GluA1 subunit at a CaMKII locus (GluA1 Ser831) in the LHb of ethanol withdrawn rats than that of age matched naïve counterparts. GRIA1 addiction relapse 28495973 Intra NAc xCT knockdown prevented ceftriaxone from attenuating reinstatement and from upregulating GLT 1 and resulted in increased surface expression of AMPA receptor subunits GluA1 and GluA2. GRIA1 addiction relapse 28495973 Intra NAc GLT 1 knockdown also prevented ceftriaxone from attenuating reinstatement and from upregulating xCT expression, without affecting GluA1 and GluA2 expression. GRIA1 drug cocaine 28495973 In the absence of cocaine or ceftriaxone treatment, xCT knockdown in the NAc increased the expression of both GluA1 and GluA2 without affecting GLT 1 expression while GLT 1 knockdown had no effect. GRIA1 drug psychedelics 28479397 However, males and females administered 5 mg/kg ketamine displayed increased protein expression of AMPA receptors (GluA1). GRIA1 drug alcohol 28270566 Profiling of the OFC synaptome identified alcohol sensitive proteins that control glutamate release (e.g., SV2A, synaptogyrin 1) and postsynaptic signaling (e.g., GluA1, PRRT2) with no changes in synaptic GABAergic proteins. GRIA1 drug amphetamine 28223211 Using protein cross linking, biochemical, subcellular fractionation, and slice electrophysiological approaches in the NAcc, we found that, unlike cocaine, previous exposure to amphetamine did not increase cell surface levels of either GluA1 or GluA2 AMPA receptor subunits, redistribution of these subunits to the synaptic or perisynaptic cellular membrane domains, protein protein associations required to support the accumulation and retention of AMPA receptors in the PSD, or the peak amplitude of AMPA receptor mediated mEPSCs recorded in NAcc slices. GRIA1 drug cocaine 28223211 Using protein cross linking, biochemical, subcellular fractionation, and slice electrophysiological approaches in the NAcc, we found that, unlike cocaine, previous exposure to amphetamine did not increase cell surface levels of either GluA1 or GluA2 AMPA receptor subunits, redistribution of these subunits to the synaptic or perisynaptic cellular membrane domains, protein protein associations required to support the accumulation and retention of AMPA receptors in the PSD, or the peak amplitude of AMPA receptor mediated mEPSCs recorded in NAcc slices. GRIA1 drug amphetamine 28223211 On the other hand, exposure to amphetamine significantly slowed mEPSC decay times and increased levels in the PSD of PKA and CaMKII as well as phosphorylation by these kinases of the GluA1 S845 and S831 residues selectively in this cellular compartment. GRIA1 drug cocaine 28223211 Rather than increase the number of surface and synaptic AMPA receptors as with cocaine, this mechanism could increase NAcc medium spiny neuron reactivity to glutamate afferents by increasing the phosphorylation state of critical regulatory sites in the AMPA receptor GluA1 subunit in the PSD. GRIA1 drug cocaine 28194001 In the present study, we directly manipulated Cav1.3 channels in Cav1.2 dihydropyridine insensitive mutant mice and found that ventral tegmental area (VTA) Cav1.3 channels mediate cocaine related and depressive like behavior through a common nucleus accumbens (NAc) shell calcium permeable α amino 3 hydroxy 5 methyl 4 isoxazolepropionic acid receptor (CP AMPAR) mechanism that requires GluA1 phosphorylation at S831. GRIA1 drug cocaine 28194001 In contrast to the cocaine and depression related phenotypes, GluA1/A2 AMPARs in the NAc core mediated social deficits, independent of S831 GluA1 phosphorylation. GRIA1 drug alcohol 28045462 Here we use ethanol (EtOH) to show that interoceptive cues are encoded through the hippocampus by mechanisms that involve increased phosphorylation of GluR1 on serine 845, and biophysical alterations in neuronal membranes that facilitate stabilization of surface located calcium permeable n 2 amino 3 (5 methyl 3 oxo 1,2 oxazol 4 yl) propanoic acid (AMPA) receptor (AMPAR) into membrane microdomains. GRIA1 drug psychedelics 27934938 Western blot results showed levels of GluA1, p S845 and p S831 proteins demonstrated significant decline with ketamine 60 mg/kg until six months administration paradigm. GRIA1 drug psychedelics 27934938 Our results indicate that reduced expression levels and decreased phosphorylation levels of hippocampal post synaptic membrane GluA1 containing AMPA receptors maybe involved in cognition impairment after long term ketamine administration. GRIA1 addiction relapse 27863698 Targeted investigation of GRIA1, a glutamatergic gene implicated in drug seeking behavior, verified the increased enrichment of lysine 27 acetylated histone H3 at discrete loci, accompanied by enhanced chromatin accessibility at hyperacetylated regions in the gene body.

GRIA1 addiction reward 27376947 Food restriction increased persistence of morphine CPP and preference scores correlated with pSer845 GluA1 in NAc core and shell. GRIA1 drug opioid 27376947 Food restriction increased persistence of naloxone CPA and elevated pSer845 GluA1 in NAc core and shell, and aversion scores were negatively correlated with pERK1 and pERK2 in NAc core. GRIA1 addiction aversion 27376947 Food restriction increased persistence of naloxone CPA and elevated pSer845 GluA1 in NAc core and shell, and aversion scores were negatively correlated with pERK1 and pERK2 in NAc core. GRIA1 drug opioid 27376947 A mechanistic scheme, attributing these effects to upregulation of pSer845 GluA1, but subject to override by CPA specific, pERK2 mediated extinction learning, is explored to accommodate opposite effects of food restriction on LiCl and naloxone CPA. GRIA1 drug opioid 27225765 Using a protein cross linking approach, we found that the surface/intracellular ratio of NAc GluA1, but not GluA2, increased with morphine treatment, suggesting postsynaptic insertion of GluA2 lacking AMPARs. GRIA1 drug opioid 27225765 Naloxone decreased the surface/intracellular ratio and synaptosomal membrane levels of NAc GluA1 in morphine dependent rats, suggesting a compensatory removal of AMPARs from synaptic zones. GRIA1 drug opioid 27225765 Together, these findings indicate that chronic morphine increases synaptic availability of GluA1 containing AMPARs in the NAc, which is necessary for triggering negative affective states in response to naloxone.

GRIA1 addiction withdrawal 27038592 Incubation with chronic EtOH for 7 days and its removal from the medium induced a significant decrease in GluA1 and GluA2 expression levels; a significant reduction in the expression of synaptophysin and GluN2A was observed only after EtOH withdrawal. GRIA1 drug cocaine 26881139 Surface biotinylation analysis of protein expression in the dlSTR revealed that, in cocaine animals, intra dlSTR MTEP administration decreased mGlu5 surface expression and prevented changes in Arc and GluA1/GluA2 observed in their vehicle counterparts. GRIA1 drug cocaine 26811312 Results showed that acute cocaine administration induced an overall down regulation of glutamate related gene expression and, specifically, a low phosphorylation level of GluA1. GRIA1 drug alcohol 26791202 mTORC1 is critically involved in RNA to protein translation, and we found that the first alcohol session rapidly activated mTORC1 in NAc shell D1+ neurons and increased synaptic expression of the AMPAR subunit GluA1 and the scaffolding protein Homer. GRIA1 drug alcohol 26742808 Here, we show that low dose alcohol (0.6 g/kg/30 minutes) self administration increases phosphorylation (activation) of AMPAR subtype GluA1 S831 (pGluA1 S831) in the central amygdala (CeA), basolateral amygdala and nucleus accumbens core (AcbC) of selectively bred alcohol preferring P rats as compared with behavior matched (non drug) sucrose controls. GRIA1 drug alcohol 26742808 Because GluA1 S831 is a Ca2+/calmodulin dependent protein kinase II (CaMKII) substrate, we sought to determine if AMPAR regulation of enhanced alcohol self administration is dependent on CaMKII activity. GRIA1 addiction relapse 26706696 Here we investigated the effects of ceftriaxone (100 and 200 mg/kg) on context primed relapse following abstinence without extinction training and examined the effects of ceftriaxone on GluA1, GluA2 and GLT 1 expression. GRIA1 drug cocaine 26706696 GluA1 was reduced in the NAc by both doses of ceftriaxone while GluA2 expression was unchanged, indicating that ceftriaxone altered AMPA subunit composition following cocaine.

GRIA1 drug amphetamine 23345217 Amphetamine exposure transiently increases Ca(2+)/calmodulin dependent protein kinase II (CaMKII) α expression in the nucleus accumbens (NAcc) shell and this persistently increases local GluA1 S831 phosphorylation and enhances behavioral responding to the drug. GRIA1 drug amphetamine 23345217 Remarkably, this transient inhibition of CaMKII activity produced a long lasting reversal of the increased GluA1 S831 phosphorylation levels in NAcc shell and persistently blocked the enhanced locomotor response to and self administration of amphetamine normally observed in rats previously exposed to the drug. GRIA1 drug psychedelics 23303054 Cell surface biotinylation studies showed that both GLYX 13 and ketamine led to increases in both NR2B and GluR1 protein levels, as measured by Western analysis, whereas no changes were seen in mRNA expression (microarray and qRT PCR). GRIA1 drug alcohol 23100433 LTP is mediated by the insertion of AMPAR subunits into the synaptic membrane, and we found that repeated systemic administration of ethanol, as well as cycles of excessive ethanol consumption and withdrawal, produced a long lasting increase in synaptic localization of the GluR1 and GluR2 subunits of AMPARs in the DMS.

GRIA1 drug opioid 23073238 In tissue slices of mPFC, the combined addition of the opioid agonist leu enkephalin and the DA D1 like receptor agonist SKF 81297 produced more than additive increase in the phosphorylation state of AMPA and NMDA receptor subunits GluR1 and NR1, respectively. GRIA1 drug cocaine 22882295 In the NAc from the stress plus cocaine group we observed a decrease in the phosphorylation of two ABPs, cofilin and cortactin, and an increase in the PSD size and the surface expression of GluR1, consistent with a more highly branched actin cytoskeleton. GRIA1 drug cocaine 22882295 This study shows that a history of repeated stress alters the ability of a subsequent cocaine injection to modulate dendritic spine morphology, actin dynamics and GluR1 expression in the NAc. GRIA1 drug cocaine 22882295 Furthermore, by regulating GluR1 expression in the NAc, elevated actin cycling contributes to the expression of cross sensitization between stress and cocaine, while stress induced changes in the Pfc were not associated with cross sensitization.

GRIA1 addiction withdrawal 22830051 FZP withdrawal is correlated with synaptic incorporation of homomeric GluA1 containing α amino 3 hydroxy 5 methylisoxazole 4 propionic acid receptors (AMPARs) in the proximal stratum radiatum of CA1 neurons. GRIA1 addiction withdrawal 22830051 After 2 days of withdrawal, Ca(2+)/calmodulin dependent protein kinase II (CaMKII) phosphorylates GluA1 subunits at Ser(831), increasing channel conductance. GRIA1 drug opioid 22675452 Importance of GluA1 subunit containing AMPA glutamate receptors for morphine state dependency. GRIA1 drug opioid 22675452 Here, mice deficient in AMPA type glutamate receptor GluA1 subunits were first conditioned to morphine (10 or 20 mg/kg s.c. during eight sessions over four days) using an unbiased procedure, followed by testing for conditioned place preference at morphine states that were the same as or different from the one the mice were conditioned to. GRIA1 drug opioid 22675452 In GluA1 wildtype littermate mice the same state morphine dose produced the greatest expression of place preference, while in the knockout mice no place preference was then detected. GRIA1 drug opioid 22675452 The results indicate impaired drug induced state dependency in GluA1 knockout mice, correlating with impaired opioid induced glutamate receptor neuroplasticity. GRIA1 drug alcohol 22666364 Consistent with this, Western blot analysis of the postsynaptic density fraction showed that while there was no change in expression of the AMPA GluR1 subunit, NMDA NR1 and NRB subunits were significantly increased in CIE exposed mice when examined immediately after the last episode of alcohol exposure. GRIA1 drug cocaine 22655064 Additionally in dSTR, after repeated cocaine, we observed significant increases in total GluA1, phosphorylated GluA1(Ser 845), and cell surface GluA1 in all cocaine treated animals vs. controls.

GRIA1 drug cocaine 22197517 Expression of AMPA receptor subunits (GluR1 and GluR2) and CRE binding protein (CREB) was measured in the ventral tegmental area (VTA), dorsolateral striatum (STR) and nucleus accumbens (NAc) before and after a sensitizing regimen of cocaine, with and without ICSS. GRIA1 addiction reward 22197517 Expression of AMPA receptor subunits (GluR1 and GluR2) and CRE binding protein (CREB) was measured in the ventral tegmental area (VTA), dorsolateral striatum (STR) and nucleus accumbens (NAc) before and after a sensitizing regimen of cocaine, with and without ICSS. GRIA1 addiction reward 22197517 ICSS increased GluR1 in the VTA but not NAc or STR, demonstrating selective changes in protein expression with electrical stimulation of discrete brain structures. GRIA1 drug cocaine 22197517 Repeated cocaine reduced GluR1, GluR2 and CREB expression in the NAc, and reductions of GluR1 and GluR2 but not CREB were further enhanced by ICSS. GRIA1 addiction reward 22197517 Repeated cocaine reduced GluR1, GluR2 and CREB expression in the NAc, and reductions of GluR1 and GluR2 but not CREB were further enhanced by ICSS. GRIA1 addiction reward 22127928 Finally, we found that the levels of PKMζ and GluR2 in the NAc remained unchanged, while the GluR1 levels were elevated following CPP and fully reversed by ZIP injection.

GRIA1 addiction sensitization 22072679 Hippocampal GluA1 containing AMPA receptors mediate context dependent sensitization to morphine. GRIA1 addiction sensitization 22072679 Furthermore, we demonstrated that phosphorylation of GluA1 AMPAR subunit plays a critical role in the acquisition and expression of context dependent behavioral sensitization, as this behavior is blocked by a viral vector that disrupts GluA1 phosphorylation. GRIA1 drug cocaine 21940447 Cav1.2 L type Ca²⁺ channels mediate cocaine induced GluA1 trafficking in the nucleus accumbens, a long term adaptation dependent on ventral tegmental area Ca(v)1.3 channels. GRIA1 drug cocaine 21940447 Utilizing cocaine psychomotor sensitization, we have examined phosphorylation of GluA1 at key residues serine 845 (S845) and S831, as well as GluA1 cell surface levels in the nucleus accumbens (NAc) of cocaine preexposed mice and the role of brain specific Ca(v)1.2 and Ca(v)1.3 L type Ca²⁺ channels (LTCCs), therein.

GRIA1 drug cocaine 21940447 We found higher basal levels of S845 phospho GluA1 (P GluA1) and cell surface GluA1 in the NAc following protracted withdrawal from cocaine exposure, changes that occur independently of LTCCs. GRIA1 addiction withdrawal 21940447 We found higher basal levels of S845 phospho GluA1 (P GluA1) and cell surface GluA1 in the NAc following protracted withdrawal from cocaine exposure, changes that occur independently of LTCCs. GRIA1 drug cocaine 21940447 In contrast, we found that a cocaine challenge that elicits expression of the cocaine sensitized response increases S831 P GluA1 that further increases surface GluA1 beyond the higher basal levels. GRIA1 drug cocaine 21940447 Intra NAc pharmacological manipulations indicate that the Ca(v)1.2 activated CaM kinase II (CaMKII) mediates cocaine induced increase in S831 P GluA1 and that both Ca(v)1.2 activated CaMKII and extracellular signal regulated kinase 2 (ERK2) mediate the increase in GluA1 cell surface levels specific to the sensitized response. GRIA1 drug cocaine 21940447 Together, these results identify candidate pathways that mediate cocaine induced AMPAR plasticity in the NAc and provide a mechanism linking LTCCs and GluA1 plasticity to cocaine induced persistent behavioral changes. GRIA1 drug cocaine 21887497 These behavioural changes were associated to alterations on the expression of metabotropic mGLUR3 glutamate receptors and on the actions of cocaine on the GLUR1 subunit of AMPA glutamate receptors in the hippocampus of maLPA(1) animals. GRIA1 drug cocaine 21640333 Enhanced cocaine conditioned place preference and associated brain regional levels of BDNF, p ERK1/2 and p Ser845 GluA1 in food restricted rats. GRIA1 drug cocaine 21640333 On the other hand, FR rats, whether injected with cocaine or vehicle, displayed elevated p ERK1/2 and p Ser845 GluA1 in dorsal hippocampus. GRIA1 drug cocaine 21640333 The one effect observed exclusively in cocaine treated FR rats was increased p Ser845 GluA1 in nucleus accumbens. GRIA1 drug cocaine 21613507 Here we show that daily intravenous cocaine self administration, but not passive cocaine administration, induces dynamic upregulation of the AMPA glutamate receptor subunits GluR1 and GluR2 in the ventral tegmental area (VTA) of rats. GRIA1 drug cocaine 21613507 We investigated the functional significance of GluR1 upregulation in the VTA on cocaine self administration using localized viral mediated gene transfer. GRIA1 drug cocaine 21613507 In cocaine self administering animals, overexpression of GluR1(WT) in the VTA markedly increased the motivation for cocaine injections on a progressive ratio schedule of cocaine reinforcement. GRIA1 addiction reward 21613507 In cocaine self administering animals, overexpression of GluR1(WT) in the VTA markedly increased the motivation for cocaine injections on a progressive ratio schedule of cocaine reinforcement.

GRIA1 addiction reward 21613507 In contrast, overexpression of protein kinase A resistant GluR1(S845A) in the VTA reduced peak rates of cocaine self administration on a fixed ratio reinforcement schedule. GRIA1 drug cocaine 21613507 Neither viral vector altered sucrose self administration, and overexpression of GluR1(WT) or GluR1(S845A) in the adjacent substantia nigra had no effect on cocaine self administration. GRIA1 drug amphetamine 21564097 Consistent with these findings, preventing GluR1 phosphorylation with the alanine mutant GluR1(S845A) reduces glutamate evoked currents in cultured medium spiny neurons and blocks the locomotor activity produced by NAcc amphetamine.

GRIA1 drug cocaine 21216391 Among them, GluA1 and GluA3 are preferentially upregulated in their palmitoylation levels by a systemic injection of cocaine. GRIA1 drug cocaine 21215761 However, there is no ultrastructural evidence that the absence of cocaine following repeated administrations affects the critical surface/synaptic availability of AMPAR GluR1 subunits in either DA or non DA, putative GABAergic neurons within the VTA. GRIA1 drug cocaine 21215761 At each time point, both cocaine and saline injected mice showed AMPAR GluR1 immunogold labeling in somatodendritic profiles, many of which contained immunoperoxidase labeling for the DA synthesizing enzyme, tyrosine hydroxylase (TH). GRIA1 drug cocaine 21215761 At 30 min after the last injection, when cocaine was systemically present, only the non TH labeled dendrites showed a significant increase in the synaptic/plasmalemmal density of GluR1 immunogold particles. GRIA1 drug cocaine 21215761 At 72 h, when systemic cocaine was depleted, synaptic GluR1 labeling was greatly enhanced in TH containing dendrites throughout the VTA and in non TH dendrites of the limbic associated paranigral VTA. GRIA1 drug cocaine 21215761 Our results demonstrate that systemic cocaine produces GluR1 trafficking specifically in non DA neurons of the VTA, which may subsequently contribute to the abstinent induced enhancement of AMPA receptor synaptic transmission in mesocorticolimbic DA neurons leading to heightened drug seeking behavior.

GRIA1 drug opioid 21126734 In line with the GluA1 PSD 95 implications of enhanced synaptic plasticity, Homer 1b/c protein expression was increased in both heroin and cocaine users as was its binding partner, dynamin 3. GRIA1 drug alcohol 21041654 We further show that the protein expression levels of GluR1 and Homer, two synaptic proteins whose translation has been shown to be modulated by mTORC1, are up regulated in the NAc of rodents with a history of excessive alcohol consumption. GRIA1 drug cocaine 20942997 Following re exposure to a cocaine paired context, surface expression of the AMPA type glutamate receptor GluR1 was significantly reduced whereas GluR2 was significantly increased in the dlCPu, independent of Arc antisense ODN infusion.

GRIA1 drug cocaine 20868701 In these mice, neither cocaine nor minocycline 4 day treatment altered GluR1 phosphorylation. GRIA1 drug cocaine 20868701 In WT mice in which minocycline inhibited development of cocaine sensitization, a 4 day cocaine treatment increased GluR1 phosphorylation at both Ser831 and Ser845 sites in the frontal cortex but not the striatum; further, this effect was prevented by minocycline. GRIA1 addiction sensitization 20868701 In WT mice in which minocycline inhibited development of cocaine sensitization, a 4 day cocaine treatment increased GluR1 phosphorylation at both Ser831 and Ser845 sites in the frontal cortex but not the striatum; further, this effect was prevented by minocycline. GRIA1 drug cocaine 20868701 Under basal conditions and in response to a single cocaine injection the levels of GluR1, GluR2, and GluR3 AMPA receptor subunits did not differ between WT and 5 LOX deficient mice, but the response of GluR1 phosphorylation to a single cocaine injection was greater under the 5 LOX deficiency.

GRIA1 drug cocaine 20553819 Acute and chronic cocaine differentially alter the subcellular distribution of AMPA GluR1 subunits in region specific neurons within the mouse ventral tegmental area. GRIA1 drug cocaine 20553819 Cocaine administration increases AMPA GluR1 expression and receptor mediated activation of the ventral tegmental area (VTA). GRIA1 drug cocaine 20553819 To test this hypothesis, we used electron microscopic immunolabeling of AMPA GluR1 subunits and tyrosine hydroxylase (TH), the enzyme needed for dopamine synthesis, in the cortical associated parabrachial (PB) and in the limbic associated paranigral (PN) VTA of adult male C57BL/6 mice receiving either a single injection (acute) or repeated escalating doses for 14 days (chronic) of cocaine. GRIA1 drug cocaine 20553819 Conversely, TH labeled dendrites within the PN VTA showed greater surface expression of GluR1 with increases in both synaptic and plasmalemmal GluR1 immunogold density after a single injection of cocaine. GRIA1 drug cocaine 20553819 In contrast, non TH containing, presumably GABAergic dendrites showed VTA region specific changes only after repeated cocaine administration such that synaptic GluR1 decreased in the PB, but increased in the PN VTA.

GRIA1 drug cocaine 20336176 Consistent with reduced AMPA responsiveness after chronic cocaine in Narp KO mice, GluR1 was reduced in the postsynaptic density (PSD) fraction of Narp KO mice withdrawn from cocaine. GRIA1 drug opioid 20159947 Immunoblotting studies show that 12 h after morphine treatment, GluR1 subunits are increased at the postsynaptic density (PSD) and at extrasynaptic sites, whereas GluR3 subunits are only increased at the PSD, and they show how this alters receptor subunit composition. GRIA1 drug cannabinoid 19940171 Discrete disturbances of AMPA GluR1 and cannabinoid type 1 receptor expression observed in the nucleus accumbens associated with stimulus cue induced heroin seeking were normalized by CBD treatment.

GRIA1 drug cocaine 19812341 Biochemical assays of isolated mPFC tissue from postnatal rats further showed that cocaine exposure in utero caused a marked reduction in the surface expression of GABA(A) receptor subunits alpha1, beta2, and beta3, but had no effect on glutamate receptor subunit GluR1.

GRIA1 drug opioid 18815253 Region specific changes in the subcellular distribution of AMPA receptor GluR1 subunit in the rat ventral tegmental area after acute or chronic morphine administration. GRIA1 drug opioid 18815253 Indeed, chronic morphine administration is known to increase AMPA receptor glutamate receptor 1 (GluR1) subunit in the VTA. GRIA1 drug opioid 18815253 However, there is no ultrastructural evidence that morphine affects the expression or surface availability of GluR1 subunits in VTA neurons of defined distribution or transmitter phenotype. GRIA1 drug opioid 18815253 Therefore, we examined electron microscopic immunolabeling of GluR1 and tyrosine hydroxylase (TH) in two VTA regions of rats perfused 1 h after a single injection of morphine, or chronic morphine in intermittent escalating doses for 14 d, and appropriate saline controls. GRIA1 drug opioid 18815253 Acute morphine administration produced a significant increase in GluR1 immunogold particles at the plasma membrane and postsynaptic densities in both TH and non TH containing dendrites in the parabrachial VTA, a region that contains mainly prefrontal cortical projecting dopaminergic neurons involved in motivation and drug seeking behavior.

GRIA1 drug opioid 18815253 Chronic morphine administration maintained the increased synaptic GluR1 labeling in the parabrachial VTA, but also increased the number of GluR1 labeled synapses and TH immunoreactivity in dendrites of the paranigral VTA where substantially more dopaminergic neurons project to limbic structures implicated in locomotor activation and reward.

GRIA1 drug opioid 18815253 These results demonstrate a region and dose dependent redistribution of GluR1 containing AMPA receptors, which is consistent with acute morphine activation of cortical projecting VTA neurons and chronic morphine activation of limbic projecting VTA neurons. GRIA1 drug cocaine 18701074 Cocaine strengthens excitatory synapses onto midbrain dopamine neurons through the synaptic delivery of GluR1 containing AMPA receptors. GRIA1 drug cocaine 18701074 We report that in midbrain slices of cocaine treated mice, synaptic transmission was no longer strengthened when GluR1 or NR1 was abolished, while in the respective mice the drug still induced normal conditioned place preference and locomotor sensitization.

GRIA1 drug cocaine 18640148 In cocaine sensitized rats GluR1 protein was increased in the mPFC on PND37 but not in other ages. GRIA1 drug cocaine 18640148 However, cocaine pretreatment during adolescence induced a transient increase of GluR1 in the mPFC only when animals were challenged in the same age. GRIA1 drug cocaine 18554320 Enhanced CREB and DARPP 32 phosphorylation in the nucleus accumbens and CREB, ERK, and GluR1 phosphorylation in the dorsal hippocampus is associated with cocaine conditioned place preference behavior. GRIA1 drug cocaine 18554320 To better understand the mechanism of cocaine conditioned place preference we have used western blot analysis to examine changes in phosphorylation of cAMP response element binding protein (CREB), dopamine and cyclic AMP regulated phosphoprotein 32 (DARPP 32), extracellular signal regulated kinase (ERK) and GluR1, key molecular substrates altered by cocaine, in the nucleus accumbens (NAc) and dorsal hippocampus (DHC) of C57BL/6 mice.

GRIA1 drug psychedelics 18419818 The aim of the present study was to investigate the effect of repeated intermittent MDMA administration upon gene transcript expression of the glutamate transporters (EAAT1, EAAT2 1, EAAT2 2), the glutamate receptor subunits of AMPA (GluR1, GluR2, GluR3), the glutamate receptor subunits of NMDA (NR1, NR2A and NR2B), as well as metabotropic glutamate receptors (mGluR1, mGluR2, mGluR3, mGluR5) in six different brain regions. GRIA1 drug opioid 18294632 Chronic administration of morphine is associated with a decrease in surface AMPA GluR1 receptor subunit in dopamine D1 receptor expressing neurons in the shell and non D1 receptor expressing neurons in the core of the rat nucleus accumbens. GRIA1 drug opioid 18294632 Immunogold electron microscopy was used to quantify the surface expression of the AMPA GluR1 subunit in dendritic profiles of neurons in the Acb in response to intermittent 14 day non contingent injections of escalating doses of morphine, a model that parallels opioid self administration. GRIA1 drug opioid 18294632 We provide the first report that chronic morphine administration is associated with a receptor phenotypic decrease in surface trafficking of GluR1 in Acb subregions. GRIA1 drug opioid 18294632 When compared to saline injected animals, morphine produced a decrease in plasma membrane GluR1 labeling in medium and large sized D1R expressing dendritic profiles in the Acb shell. GRIA1 drug opioid 18294632 These results indicate that chronic intermittent injection of escalating doses of morphine is accompanied by ultrastructural plasticity of GluR1 in neurons that are responsive to glutamate and dopamine induced D1R activation in the Acb shell, and neurons capable of responding to glutamate but not D1R receptor stimulation in the Acb core. GRIA1 drug cocaine 18278040 Cocaine reinstatement is associated with D1 like dopamine receptor dependent increases in accumbens shell CaMKII phosphorylated on Thr286 and glutamate receptor 1 (GluR1) phosphorylated on Ser831 (a known CaMKII phosphorylation site), in addition to increases in cell surface expression of GluR1 containing AMPA receptors in the shell.

GRIA1 drug opioid 18265961 Recombinant mu delta opioid receptors (MDOR) and the glutamate receptor 1 (GluR1) subunit of amino 3 hydroxy 5 methyl 4 isoxazole propionic acid glutamate receptors are involved in acute and chronic effects of morphine. GRIA1 drug opioid 18265961 Spontaneous home cage activity, novelty induced self grooming and morphine induced hyperactivity were higher in GluR1 mice compared to Vehicle subjects, whereas MDOR immunization was associated with an increased morphine induced conditioned place preference. GRIA1 drug opioid 18265961 In response to escalating doses of morphine (from 10 to 60 mg/kg i.p., twice daily) and naloxone precipitated withdrawal (1 mg/kg subcutaneous), GluR1 mice exhibited a more marked stereotyped sniffing behavior and less body tremors compared to Vehicle subjects, whereas less sniffing and teeth chattering were found in MDOR mice. GRIA1 addiction withdrawal 18265961 In response to escalating doses of morphine (from 10 to 60 mg/kg i.p., twice daily) and naloxone precipitated withdrawal (1 mg/kg subcutaneous), GluR1 mice exhibited a more marked stereotyped sniffing behavior and less body tremors compared to Vehicle subjects, whereas less sniffing and teeth chattering were found in MDOR mice. GRIA1 drug opioid 18265961 These findings indicate an altered response to morphine related reinforcing and aversive effects in MDOR mice and altered coping with the environment in GluR1 mice. GRIA1 addiction aversion 18265961 These findings indicate an altered response to morphine related reinforcing and aversive effects in MDOR mice and altered coping with the environment in GluR1 mice.

GRIA1 drug nicotine 18261852 We investigated the effects of nicotine pre exposure on nicotine preference and levels of GluR1/2 and CREB in the mesolimbic system in male mice C57BL/6J and BALB/c inbred mice. GRIA1 drug nicotine 18261852 In addition, alterations in CREB and GluR1 levels are not sufficient to explain preference for nicotine in a 2 bottle choice paradigm.

GRIA1 drug cocaine 18160635 To mimic the longer elevation in extracellular DA levels produced by systemic cocaine, cocultures were incubated with DA for 1 h. Synaptic GluR1 was increased 24 h later, reminiscent of the increased AMPA/NMDA ratio at excitatory synapses onto VTA DA neurons 24 h after cocaine injection (Ungless et al., 2001). GRIA1 addiction relapse 18055123 The nucleus accumbens was dissected immediately after the reinstatement test to examine alterations in GluR1 and NR1 subunits of glutamatergic receptors. GRIA1 addiction relapse 18055123 GluR1 levels were decreased on days 1 and 30 but not on day 60 while NR1 levels were unaltered in the reinstatement test. GRIA1 drug amphetamine 18055123 Decreased levels of GluR1 in the nucleus accumbens might be related to the reinstatement of amphetamine induced conditioning place preference. GRIA1 addiction relapse 18055123 Decreased levels of GluR1 in the nucleus accumbens might be related to the reinstatement of amphetamine induced conditioning place preference. GRIA1 drug cocaine 17898233 Glutamate receptor 1 (GluR1) and GluR2 surface/intracellular (S/I) ratios were increased after 14 d of withdrawal in sensitized rats but were decreased 24 h after challenge with cocaine (which elicited a sensitized locomotor response) or saline (which elicited conditioned locomotion). GRIA1 addiction withdrawal 17898233 Glutamate receptor 1 (GluR1) and GluR2 surface/intracellular (S/I) ratios were increased after 14 d of withdrawal in sensitized rats but were decreased 24 h after challenge with cocaine (which elicited a sensitized locomotor response) or saline (which elicited conditioned locomotion). GRIA1 drug cocaine 17898233 JNK phosphorylation also increased after withdrawal, but after cocaine challenge, it was inversely related to GluR1 and GluR2 S/I ratios. GRIA1 addiction withdrawal 17898233 JNK phosphorylation also increased after withdrawal, but after cocaine challenge, it was inversely related to GluR1 and GluR2 S/I ratios. GRIA1 drug cocaine 17898233 In summary, surface expression of GluR1/2 containing AMPARs increased in the NAc of sensitized rats, but AMPARs internalized after a single reexposure to cocaine or cocaine related cues. GRIA1 drug amphetamine 17762518 In this study, AMPH CPP significantly increased hippocampal GluR1 receptors, though AMPH CPP was impaired by either blockade of NMDA receptors (AP5) or inhibition of CaMKII (KN 93) during conditioning.

GRIA1 drug cocaine 17680995 Moreover, in sensitized rats acute cocaine administration modified phosphorylation levels of Thr75 and Thr34 DARPP 32, GluR1, and NR1 subunits in the nucleus accumbens only at a dose double the efficacious dose in control rats. GRIA1 drug cocaine 17680995 Furthermore, in sensitized rats the acute administration of 6 methyl 2 (phenylethynyl) pyridine, a mGluR5 antagonist, reinstated the phosphorylation levels of Thr75 and Thr34 DARPP 32, GluR1, and NR1 to control values, and a subsequent cocaine challenge did not elicit a sensitized response. GRIA1 drug amphetamine 17651730 Western blot analysis of the caudate after methamphetamine revealed little change in Alpha Amino 3 Hydroxy 5 Methyl 4 Isoxazole Propionic Acid (AMPA) GluR1 or N Methyl d Aspartate (NMDA) NR2B subunits, or their phosphorylation state. GRIA1 drug amphetamine 17651730 However, methamphetamine increased levels of GluR1 and its phosphorylation state in the prefrontal cortex (PFC), and these increases were attenuated by deprenyl.

GRIA1 drug benzodiazepine 17510319 As GluR1 containing AMPARs are critical for activity dependent alterations in excitatory strength, we sought to determine whether changes in GluR1 subunit distribution in CA1 neurons occurred during benzodiazepine withdrawal. GRIA1 addiction withdrawal 17510319 As GluR1 containing AMPARs are critical for activity dependent alterations in excitatory strength, we sought to determine whether changes in GluR1 subunit distribution in CA1 neurons occurred during benzodiazepine withdrawal. GRIA1 addiction withdrawal 17510319 Confocal image analysis revealed that FZP withdrawal promoted GluR1 subunit incorporation into somatic and proximal dendritic membranes of CA1 neurons without GluR2 subunit alterations. GRIA1 addiction withdrawal 17510319 As with long term potentiation (LTP), the FZP withdrawal induced GluR1 incorporation into CA1 neuron membranes may require the GluR1 trafficking protein, synapse associated protein 97, which was also elevated in membrane associated fractions. GRIA1 addiction withdrawal 17510319 Together, our findings provide evidence that during FZP withdrawal, increased membrane incorporation of GluR1 containing AMPARs and associated up regulation of AMPAR functions in hippocampal CA1 pyramidal neurons share fundamental similarities with the mechanisms underlying LTP. GRIA1 drug cocaine 17439498 Chronic cocaine produced region and substrate specific tolerance to cAMP dependent protein phosphorylation, including GluR1(S845) phosphorylation in striatal and amygdala subregions and NR1(S897) phosphorylation in the CA1 subregion of the hippocampus. GRIA1 drug cocaine 17276011 Importantly, there was an increase in the percentage of cells colabeled with Fos and GluR1 in the anterior cingulate and nucleus accumbens shell and cells colabeled with Fos and GluR4 in the infralimbic cortex, suggesting that within these regions, a greater, and perhaps even different, population of AMPA receptor subunit expressing neurons is activated in rats engaged in cocaine seeking behavior.

GRIA1 addiction reward 17093088 Here, we used herpes simplex virus vectors to examine how transient increases in the expression of GluR1 or GluR2 protein in the shell component of NAc affect the rewarding impact of electrical stimulation of the medial forebrain bundle, as reflected by intracranial self stimulation (ICSS) thresholds in rats. GRIA1 drug opioid 17093088 We found that elevated GluR1 in NAc shell increases ICSS thresholds, an effect similar to that caused by treatments that cause anhedonia and dysphoria (prodepressive effects) in rats and humans (e.g., drug withdrawal, kappa opioid agonists).

GRIA1 addiction sensitization 16794574 Reversal of cocaine induced behavioral sensitization and associated phosphorylation of the NR2B and GluR1 subunits of the NMDA and AMPA receptors. GRIA1 addiction sensitization 16794574 Sensitization was associated with increased NR2B expression in the accumbens (NAc) shell and decreased Tyr1472 phosphorylation in the NAc core, as well as increased Ser845 phosphorylation of the GluR1 subunit in prefrontal cortex, NAc core, and shell. GRIA1 drug opioid 16775132 However, the roles of D1 receptors, CREB, and GluR1 in morphine dependence are not well understood. GRIA1 addiction dependence 16775132 However, the roles of D1 receptors, CREB, and GluR1 in morphine dependence are not well understood. GRIA1 drug opioid 16775132 Here, we show that somatic signs of naloxone precipitated withdrawal were associated with increased P CREB, but not P GluR1, in the NAc of morphine dependent rats. GRIA1 addiction withdrawal 16775132 Here, we show that somatic signs of naloxone precipitated withdrawal were associated with increased P CREB, but not P GluR1, in the NAc of morphine dependent rats. GRIA1 drug opioid 16775132 Surprisingly, SKF 82958 increased P GluR1, but not P CREB, in the NAc, and naloxone reduced SKF 82958 mediated P GluR1 induction specifically in morphine dependent rats. GRIA1 addiction dependence 16775132 Furthermore, they suggest a dependence associated shift in the molecular mechanisms that regulate the consequences of D1 receptor stimulation, favoring activation of GluR1 rather than CREB. GRIA1 drug opioid 16775132 These data raise the possibility that the rewarding effects of SKF 82958 in morphine dependent rats involve increased P GluR1 in the NAc, although the involvement of other brain regions cannot be ruled out. GRIA1 drug opioid 16687214 We found that repeated administration of morphine significantly elevated aAbs levels to MDOR and to the AMPA GluR1 subunit, but not to the NMDA NR2 subunit. GRIA1 addiction addiction 16687214 Therefore, together with further investigations on their potential functional consequences, we propose a thorough exploration of aAbs to MDOR and to AMPA GluR1 subunit as early biomarkers signaling opiate addiction.

GRIA1 addiction withdrawal 16616767 Here, we have examined the expression of GluR1 and GluR2/3 in hippocampal membrane and synaptic fractions following repeated morphine exposure and subsequent withdrawal. GRIA1 drug opioid 16616767 Repeated morphine exposure for 12 d increased GluR1 and GluR2/3 in synaptosome but not in membrane fraction. GRIA1 drug opioid 16616767 However, during opiate withdrawal, GluR1 was generally reduced while GluR2/3 was prominently increased in both fractions; pCaMKIIalpha was strongly decreased immediately after withdrawal, but detectably increased in late phase of morphine withdrawal in both fractions. GRIA1 addiction withdrawal 16616767 However, during opiate withdrawal, GluR1 was generally reduced while GluR2/3 was prominently increased in both fractions; pCaMKIIalpha was strongly decreased immediately after withdrawal, but detectably increased in late phase of morphine withdrawal in both fractions. GRIA1 addiction withdrawal 16616767 These findings indicate that opiate withdrawal induces dynamic expression of GluR1 and GluR2/3 subunits of AMPA receptors in hippocampal synapses, possibly revealing an adaptive process of the hippocampal functions following opiate withdrawal. GRIA1 drug cocaine 16600521 Both knockout strains displayed increased induction of GluR1 Ser(845) phosphorylation in response to D1 receptor stimulation in slices, and also displayed enhanced locomotor activation in response to cocaine administration. GRIA1 drug cocaine 16495937 AMPA receptor GluR1 subunits are involved in the control over behavior by cocaine paired cues. GRIA1 drug cocaine 16495937 Here, we examine the consequences of targeted deletion of the gene encoding GluR1 subunits of AMPA receptors (gria1 knockouts (KO)) on cocaine self administration and on the ability of cocaine paired cues to affect cocaine seeking in mice.

GRIA1 addiction relapse 16495937 Here, we examine the consequences of targeted deletion of the gene encoding GluR1 subunits of AMPA receptors (gria1 knockouts (KO)) on cocaine self administration and on the ability of cocaine paired cues to affect cocaine seeking in mice. GRIA1 drug cocaine 16495937 Cocaine self administration was unaffected by gria1 deletion, as was the ability of a cocaine paired cue to reinstate responding following extinction, following either a 3 or a 66 day delay. GRIA1 drug cocaine 16495937 These studies indicate that GluR1 containing AMPA receptors are not involved in cocaine self administration, cue induced reinstatement of cocaine seeking, or incubation of the cocaine seeking response. GRIA1 addiction relapse 16495937 These studies indicate that GluR1 containing AMPA receptors are not involved in cocaine self administration, cue induced reinstatement of cocaine seeking, or incubation of the cocaine seeking response.

GRIA1 addiction relapse 16495937 As with cocaine, there were no effects of gria1 deletion on food self administration or cue induced reinstatement, and KOs over responded during extinction. GRIA1 addiction reward 16495937 These data indicate that GluR1 containing AMPA receptors are important in stimulus reward learning, though the method of cue reward association formation, the reward class, and the behavioral end point are critical variables in determining their involvement. GRIA1 drug cocaine 16363995 Statistically significant elevations were observed for NR1, GluR1, GluR2/3 and GluR5 (p < 0.05) and a trend towards increased NR1 phosphorylated at serine 896 (p = 0.07) in the NAc but not putamen of monkeys self administering cocaine compared with controls. GRIA1 drug cocaine 16207873 Surface/intracellular (S/I) ratios for glutamate receptor 1 (GluR1) and GluR2/3 subunits were increased 21 d after the last injection in cocaine sensitized rats but not rats that failed to sensitize, and the magnitude of the S/I ratio for cocaine sensitized rats was positively correlated with the magnitude of behavioral sensitization. GRIA1 addiction sensitization 16207873 Surface/intracellular (S/I) ratios for glutamate receptor 1 (GluR1) and GluR2/3 subunits were increased 21 d after the last injection in cocaine sensitized rats but not rats that failed to sensitize, and the magnitude of the S/I ratio for cocaine sensitized rats was positively correlated with the magnitude of behavioral sensitization. GRIA1 drug cocaine 16046859 Tissue samples of the nucleus accumbens (NAc) and striatum (Str) of all four prenatal treatment groups were examined to determine whether alterations in the transcription factor CREB or glutamate receptor subunit, GluR1, induced by prenatal cocaine treatment may have contributed to the altered behavioral responses. GRIA1 drug opioid 16037950 Increased AMPA GluR1 receptor subunit labeling on the plasma membrane of dendrites in the basolateral amygdala of rats self administering morphine. GRIA1 drug opioid 16037950 High resolution immunogold electron microscopic immunocytochemistry was used to compare surface and intracellular labeling of the calcium sensitive AMPA GluR1 receptor subunit in the basolateral (BLA) and central (CeA) nuclei of the amygdala in rats self administering escalating doses of morphine or saline. GRIA1 drug opioid 16037950 Morphine self administration was associated with regionally diverse effects on dendritic GluR1 targeting in the BLA and CeA. GRIA1 drug opioid 16037950 In the BLA of morphine self administering animals, there was a significant increase in the proportion of immunogold particles for GluR1 on the plasma membrane of dendrites, particularly in association with extrasynaptic sites, which was most prominent in large (2 4 microm) profiles. GRIA1 drug opioid 16037950 In both amygdala regions, GluR1 and the micro opioid receptor, the major cellular target of morphine, were only infrequently colocalized. GRIA1 drug opioid 16037950 These results indicate that GluR1 targeting is a dynamic process that can be differentially affected in distinct amygdala regions in response to chronic self administration of morphine. GRIA1 addiction withdrawal 15970947 In the brains of these rats, withdrawal anxiety was accompanied by increased [3H]Ro48 8587 binding in the hippocampus and thalamus, and decreased GluR1 and GluR2 subunit mRNA expression in the amygdala (GluR1 and GluR2) and cortex (GluR1).

GRIA1 drug cocaine 15548228 A single high dose of cocaine induces behavioural sensitization and modifies mRNA encoding GluR1 and GAP 43 in rats. GRIA1 addiction sensitization 15548228 A single high dose of cocaine induces behavioural sensitization and modifies mRNA encoding GluR1 and GAP 43 in rats. GRIA1 drug cocaine 15548228 The present study investigated whether in Sprague Dawley rats a single, behavioural sensitizing dose of cocaine is sufficient to induce changes in the mRNA levels of growth associated protein 43 (GAP 43), an important protein in mediating experience dependent plasticity and synaptic reorganization, and of glutamate receptor 1 (GluR1), a subunit of AMPA glutamate receptors, a protein that is up regulated with repeated cocaine. GRIA1 drug cocaine 15548228 Single dose of 20 but not 10 mg/kg cocaine 48 h before scheduled death significantly enhanced GluR1 and GAP 43 mRNA expression in the nucleus accumbens (NAc), both shell and core subregions, and ventral tegmental area (VTA).

GRIA1 drug cannabinoid 15233572 Expression of the GluR1 and GluR2/3 subunits of AMPA glutamate receptors was analyzed by immunohistochemistry in THC exposed rats at three postnatal ages: PD20 (still exposed to THC) to study the direct effect of drug exposure, and PD30 and PD70 (10 and 50 days following THC withdrawal) to analyze the long term effects of prenatal exposure.

ALDH2 drug alcohol 31697578 Introduction: Aldehyde dehydrogenase 2 (ALDH2) is a main contributor of the alcohol elimination process. ALDH2 drug alcohol 31697578 Functional polymorphism in the ALDH2 gene and its inactive form causes unpleasant flushing responses after alcohol consumption and prevents excessive alcohol intake. ALDH2 drug alcohol 31697578 Additionally, ALDH2 is involved in the elimination of metabolites of neurotransmitters like 3,4 dihydroxyphenylacetaldehyde (DOPAL) and 3,4 dihydroxyphenylglycoaldehyde (DOPGAL) in the central nervous system (CNS).Areas covered: We examine the role of ALDH2 polymorphism in disease, aging and alcohol addiction and discuss its pharmacological targeting.

ALDH2 addiction reward 31550440 Based on the theory that brain acetaldehyde accumulation is associated with the reinforcing properties of EtOH, this study sought to determine brain CAT and ALDH2 expression in limbic areas of control and Pb exposed animals after voluntary EtOH intake. ALDH2 drug alcohol 31018006 Then, alcohol dehydrogenase (ADH1) and aldehyde dehydrogenase (ALDH2) protein levels and enzymatic activities in the livers were quantified. ALDH2 drug alcohol 31018006 The studies show that treatment with fenofibrate not only increased the activity of catalase in the liver of alcohol drinking rats, as reported earlier, but also increased the levels and enzymatic activity of ADH1, while ALDH2 remained unchanged. ALDH2 drug alcohol 31018006 Tras eso, se midieron los niveles hepáticos y actividades enzimáticas de alcohol deshidrogenasa (ADH1) y de aldehído deshidrogenasa (ALDH2). ALDH2 drug alcohol 31018006 Los resultados muestran que el tratamiento con fenofibrato no solo aumenta la actividad de catalasa en el hígado de ratas bebedoras de alcohol, sino que también incrementa los niveles y la actividad de ADH1, sin alterar ALDH2. ALDH2 drug alcohol 30931596 Genetic variants in two enzymes involved in the metabolism of ethanol, alcohol dehydrogenase ADH1B *2 and aldehyde dehydrogenase ALDH2 *2 through increasing the blood level of acetaldehyde, may play a "protective" role against alcoholism. ALDH2 drug alcohol 30852706 Variations in genes affecting alcohol metabolism (ADH1B, ALDH2) are protective against both alcohol dependence and excessive consumption, but different variants are found in different populations. ALDH2 addiction dependence 30852706 Variations in genes affecting alcohol metabolism (ADH1B, ALDH2) are protective against both alcohol dependence and excessive consumption, but different variants are found in different populations. ALDH2 addiction dependence 30852706 ADH1B and ALDH2 strongly affect both consumption and dependence. ALDH2 drug alcohol 30629674 Endoscopic screening using esophageal iodine staining and genotypes of ADH1B and ALDH2 in Japanese alcohol dependent women. ALDH2 drug alcohol 30629674 Several risk factors for DIULs, including genetic polymorphisms of alcohol and aldehyde dehydrogenases (ADH1B, rs1229984; ALDH2, rs671), have been demonstrated in Japanese alcohol dependent men. ALDH2 drug alcohol 30629674 The low sensitivity in the present study suggests that a lack of alcohol flushing may play a crucial role in the development of alcohol dependence in women with inactive ALDH2. ALDH2 addiction dependence 30629674 The low sensitivity in the present study suggests that a lack of alcohol flushing may play a crucial role in the development of alcohol dependence in women with inactive ALDH2. ALDH2 drug alcohol 30629674 No significant differences in age, usual alcohol consumption, or smoking habits were observed according to ADH1B and ALDH2 genotypes. ALDH2 drug nicotine 30629674 No significant differences in age, usual alcohol consumption, or smoking habits were observed according to ADH1B and ALDH2 genotypes. ALDH2 drug alcohol 30521820 Activation of mitochondrial aldehyde dehydrogenase (ALDH2) by ALDA 1 reduces both the acquisition and maintenance of ethanol intake in rats: A dual mechanism? ALDH2 drug alcohol 30521820 Recently, it was described that N (1,3 benzodioxol 5 ylmethyl) 2,6 dichlorobenzamide (ALDA 1) activates aldehyde dehydrogenase 2 (ALDH2), enzyme that catalyzes the oxidation of ethanol derived acetaldehyde to acetate. ALDH2 drug alcohol 30521820 The study shows that the activation of ALDH2 by ALDA 1 is effective for inhibiting both the acquisition and the maintenance of chronic ethanol intake by alcohol preferring rats. ALDH2 drug alcohol 30521820 Thus, the activation of brain ALDH2 may constitute a novel approach in the treatment of alcohol use disorders. ALDH2 drug alcohol 30470859 Gene expression of enzymes involved in the metabolism of ethanol, i.e., Adh1 and Aldh2, were altered by hypothyroidism and T4/T3 supplementation. ALDH2 drug alcohol 30121625 Alcohol inhibits T cell glucose metabolism and hepatitis in ALDH2 deficient mice and humans: roles of acetaldehyde and glucocorticoids. ALDH2 drug alcohol 30121625 Individuals with inactive ALDH2 accumulate acetaldehyde after alcohol consumption. ALDH2 drug alcohol 30121625 Wild type (WT) and Aldh2 knockout (Aldh2 / ) mice were subjected to chronic ethanol feeding and concanavalin A (ConA) induced T cell hepatitis. ALDH2 drug alcohol 30121625 Ethanol feeding exacerbated ConA induced hepatitis in WT mice but surprisingly attenuated it in Aldh2 / mice despite higher acetaldehyde levels in Aldh2 / mice. ALDH2 drug alcohol 30121625 Elevation of serum cytokines and their downstream signals in the liver post ConA injection was attenuated in ethanol fed Aldh2 / mice compared to WT mice. ALDH2 drug alcohol 30121625 Finally, compared to WT mice, ethanol fed Aldh2 / mice had higher levels of serum corticosterone, a well known factor that inhibits aerobic glycolysis. ALDH2 drug alcohol 30121625 Blockade of corticosterone partially restored ConA mediated hepatitis in ethanol fed Aldh2 / mice. ALDH2 drug alcohol 30121625 Acute alcohol drinking elevated plasma cortisol and corticosterone levels in human subjects with higher levels in those with inactive ALDH2 than those with active ALDH2. ALDH2 drug alcohol 30121625 ALDH2 deficiency is associated with elevated acetaldehyde and glucocorticoids post alcohol consumption, thereby inhibiting T cell activation and hepatitis.

ALDH2 drug alcohol 28750942 A standardized extract of the fruit of Hovenia dulcis alleviated alcohol induced hangover in healthy subjects with heterozygous ALDH2: A randomized, controlled, crossover trial. ALDH2 drug alcohol 28750942 Twenty six eligible male adults with heterozygous ALDH2 (23.7±0.3 years old) consumed 360mL of Korean Soju (50g alcohol) together with HDE (2460mg) or matched placebo with subsequent crossover.

ALDH2 drug alcohol 28728635 This study examined ALDH2 gene status as a moderator of the associations between parental drinking, peer drinking, and acculturation with alcohol use among 222 Chinese American and Korean American college freshmen. ALDH2 drug alcohol 28728635 Negative binomial regressions were used to test the main and interactive effects of ALDH2 with contextual factors on alcohol frequency (drinking days) and quantity (drinks per drinking day) in the past 3 months. ALDH2 drug alcohol 28728635 ALDH2*2 was associated with more subjective flushing symptoms and longer length of flushing but was unrelated to both alcohol frequency and quantity. ALDH2 drug alcohol 28728635 Peer drinking was positively associated with both alcohol frequency and quantity, but neither was moderated by ALDH2. ALDH2 drug alcohol 28728635 We observed a nonsignificant trend for the interaction between parental drinking and ALDH2 on alcohol frequency, where parental drinking was positively associated with alcohol frequency only among participants with ALDH2*2. ALDH2 drug alcohol 28728635 We found a significant interaction between acculturation and ALDH2 on alcohol frequency, where acculturation was positively associated with alcohol frequency only among those with ALDH2*2. ALDH2 drug alcohol 28728635 Parental drinking and acculturation may facilitate more frequent drinking among those who have more intense reactions to alcohol (i.e., those with ALDH2*2) during the transition from high school to college. ALDH2 drug alcohol 28578603 Most ethanol is broken down in the liver in two steps by alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH2) enzymes, which metabolize down ethanol into acetaldehyde and then acetate. ALDH2 drug alcohol 28578603 These results suggest that gene therapy could be a useful tool for the treatment of alcoholism by knocking down ALDH2 expression using shRNA technology delivered by AAV vectors. ALDH2 drug alcohol 28485404 We observed the strongest association between the previously reported single nucleotide polymorphism (SNP) rs671 in ALDH2 and alcohol drinker status (odd ratio (OR)=0.40, P=2.28 × 10 72) in East Asians, and also an effect on drinks/week (beta= 0.17, P=5.42 × 10 4) in the same group. ALDH2 drug alcohol 28485404 Although prior studies reported effects of ADH1B and ALDH2 on lifetime measures, such as risk of alcohol dependence, our study adds further evidence of the effect of the same genes on a cross sectional measure of average drinking. ALDH2 addiction dependence 28485404 Although prior studies reported effects of ADH1B and ALDH2 on lifetime measures, such as risk of alcohol dependence, our study adds further evidence of the effect of the same genes on a cross sectional measure of average drinking. ALDH2 drug alcohol 28471244 The ALDH2*2 allele (A allele) at rs671 is more commonly carried by Asians and is associated with alcohol related flushing, a strong adverse reaction to alcohol that is protective against drinking. ALDH2 drug alcohol 28471244 This study examined the interplay between ALDH2*2, peer drinking, and alcohol consumption in college students. ALDH2 drug alcohol 28471244 We hypothesized that the relationship between ALDH2*2 and standard grams of ethanol per month would vary based on the level of peer drinking. ALDH2 drug alcohol 28471244 Main effects of ALDH2*2( ) and having more friends who got drunk were associated with greater alcohol consumption. ALDH2 drug alcohol 28471244 The ALDH2*2 × peer drunkenness interaction showed a stronger positive association with alcohol consumption for ALDH2*2( ) versus ALDH2*2(+) at increasing levels of peer drunkenness. ALDH2 drug alcohol 28471244 Follow up comparisons within each peer drunkenness level identified significantly higher alcohol consumption for ALDH2*2( ) compared to ALDH2*2(+) at the all friends got drunk level. ALDH2 drug alcohol 28471244 There was evidence of a stronger effect for ALDH2*2( ) compared to ALDH2*2(+) with greater alcohol use when students were more exposed to peer drinking.

ALDH2 drug alcohol 28109342 Systemic CY administration reduced the elevated ethanol intake already reported in the Pb exposed animals (but not in the controls) accompanied by liver (but not brain) ALDH2 inactivation. ALDH2 drug alcohol 28109342 CY administration enhanced both ethanol intake and locomotor activity accompanied by brain ALDH2 inactivation in control animals, while an increase in ethanol consumption was also observed in the Pb exposed group, although in the absence of brain ALDH2 blockade. ALDH2 drug alcohol 28098394 The inactive aldehyde dehydrogenase 2 (ALDH2) and highly active alcohol dehydrogenase 1B (ADH1B) genes are protective factors for the development of AUD. ALDH2 drug alcohol 28098394 The inactive ALDH2 provides its protective effect through the accumulation of acetaldehyde after consuming alcohol, resulting in unpleasant effects, and heightened sensitivity to alcohol.

ALDH2 drug alcohol 28032633 PPT enhanced catalase, DPN reduced ALDH2, while G1 had no effect on the activity of either enzyme, and none of the agonists influenced alcohol dehydrogenase or CYP2E1 activities in the myocardium. ALDH2 drug alcohol 27991683 We evaluated 989 Japanese alcoholic men to identify the effects of genetic polymorphisms of alcohol dehydrogenase 1B (ADH1B; rs1229984) and aldehyde dehydrogenase 2 (ALDH2; rs671) on platelet counts during an 8 week in hospital abstinence period. ALDH2 drug alcohol 27991683 In alcoholics, the ADH1B*1/*1 genotype increased the risk of thrombocytopenia upon admission and of a rebound platelet increase 2 weeks thereafter, while the ALDH2*1/*1 genotype was associated with lower platelet counts throughout the 8 week hospital stay. ALDH2 drug alcohol 27404720 Acetaldehyde generated from alcohol in the liver is metabolized by the mitochondrial aldehyde dehydrogenase (ALDH2) such that diminishing ALDH2 activity leads to the aversive effects of blood acetaldehyde upon alcohol intake. ALDH2 addiction aversion 27404720 Acetaldehyde generated from alcohol in the liver is metabolized by the mitochondrial aldehyde dehydrogenase (ALDH2) such that diminishing ALDH2 activity leads to the aversive effects of blood acetaldehyde upon alcohol intake. ALDH2 drug alcohol 27404720 Ethanol intake was curtailed 47% for 34 days (P < 0.0001), while blood acetaldehyde more than doubled upon ethanol administration and ALDH2 activity dropped 25% in liver homogenates, not affecting other ALDH isoforms. ALDH2 drug alcohol 27404720 Thus, hairpin ribozymes targeted to 16 nt in the ALDH2 mRNA provide durable and specific effects in vivo, representing an improvement on previous work and encouraging development of gene therapy for alcoholism.

ALDH2 drug alcohol 27186430 A polymorphic mutation in the acetaldehyde dehydrogenase 2 (ALDH2) gene has been epidemiologically linked to the high susceptibility to esophageal carcinogenesis for individuals with alcohol use disorders. ALDH2 drug alcohol 27186430 Mice subjected to alcohol drinking show increased oxidative stress and DNA adduct formation in esophageal epithelia where Aldh2 loss augments alcohol induced genotoxic effects; however, it remains elusive as to how esophageal epithelial cells with dysfunctional Aldh2 cope with oxidative stress related to alcohol metabolism. ALDH2 drug alcohol 27186430 Aldh2 deficient cells appeared to be highly susceptible to ethanol or acetaldehyde mediated toxicity. ALDH2 drug alcohol 27186430 Alcohol dehydrogenase mediated acetaldehyde production was implicated in ethanol induced cell injury in Aldh2 deficient cells as ethanol induced oxidative stress and cell death was partially inhibited by 4 methylpyrazole.

ALDH2 drug alcohol 25354396 Contribution of ALDH2 polymorphism to alcoholism associated hypertension. ALDH2 drug alcohol 25354396 Although oxidative stress and endothelial injury have been postulated to play a major contributing role to alcoholism induced hypertension, recent evidence depicted a rather unique role for the genotype of the acetaldehyde metabolizing enzyme mitochondrial aldehyde dehydrogenase (ALDH2), which is mainly responsible for detoxifying ethanol consumed, in alcoholism induced elevation of blood pressure. ALDH2 drug alcohol 25354396 Genetic polymorphism of ALDH2 in human results in altered ethanol pharmacokinetic properties and ethanol metabolism, leading to accumulation of the ethanol metabolite acetaldehyde following alcohol intake. ALDH2 drug alcohol 25354396 The unfavorable consequence of the ALDH2 variants is believed to be governed by the accumulation of the ethanol metabolite acetaldehyde. ALDH2 drug alcohol 25354396 The aim of this mini review is to summarize the possible contribution of ALDH2 genetic polymorphism in the onset and development of alcoholism related development of hypertension.

ALDH2 drug alcohol 24661165 This study examined growth trajectories of alcohol consumption (frequency, average quantity, binge drinking, maximum drinks) and problems over the college years and then tested whether the ALDH2 genotype mediated or moderated the relationship between alcohol consumption and problems. ALDH2 addiction intoxication 24661165 This study examined growth trajectories of alcohol consumption (frequency, average quantity, binge drinking, maximum drinks) and problems over the college years and then tested whether the ALDH2 genotype mediated or moderated the relationship between alcohol consumption and problems. ALDH2 drug alcohol 24661165 Alcohol consumption and problems increased over the college years for both those with and without ALDH2∗2, but having an ALDH2∗2 allele was associated with less of an increase in problems over time. ALDH2 addiction intoxication 24661165 A mediation model was supported, with ALDH2∗2 group differences in problems fully accounted for by differences in frequency of binge drinking. ALDH2 drug alcohol 24661165 Findings also supported a moderation hypothesis: All four alcohol consumption variables were significant predictors of subsequent alcohol problems, but these relationships were not as strong in those with ALDH2∗2 as in those without ALDH2∗2. ALDH2 drug alcohol 24661165 Our findings suggest that the interplay between ALDH2∗2 and drinking related problems is complex, involving both mediation and moderation processes that reduce the likelihood of developing problems via reduction of heavy drinking as well as by altering the relationship between alcohol consumption and problems.

ALDH2 drug alcohol 22563891 Developmental trajectory and environmental moderation of the effect of ALDH2 polymorphism on alcohol use. ALDH2 drug alcohol 22563891 In the aldehyde dehydrogenase 2 (ALDH2) gene, the ALDH2*2 allele, prevalent in East Asian populations, encodes an enzyme with severely reduced activity, thereby disrupting the normal metabolism of alcohol. ALDH2 drug alcohol 22563891 Possession of the ALDH2*2 allele has been repeatedly shown to be associated with lower risk for alcohol dependence and reduced alcohol use. ALDH2 addiction dependence 22563891 Possession of the ALDH2*2 allele has been repeatedly shown to be associated with lower risk for alcohol dependence and reduced alcohol use. ALDH2 drug alcohol 22563891 We also sought to determine whether the environmental influences of nonbiological parent and elder sibling alcohol use and misuse, as well as deviant peer behavior, moderated the effect of ALDH2 genotype upon alcohol use. ALDH2 drug alcohol 22563891 Across all measures of alcohol use, the association between ALDH2*2 allele possession and reduced drinking went from negligible to moderate between mid adolescence and early adulthood. ALDH2 drug alcohol 22563891 A combined index of adoptive parent alcohol use and misuse consistently moderated the protective effect of the ALDH2*2 allele across the measures of quantity and frequency of alcohol use, and symptomology, such that high parental alcohol use and misuse reduced the protective effect of the ALDH2*2 allele, while low parental alcohol use and misuse enhanced the effect of the allele. ALDH2 drug alcohol 22563891 Neither a combined index of elder sibling alcohol use and misuse, nor deviant peer behavior was consistently related to the effect of ALDH2 genotype. ALDH2 drug alcohol 22563891 The protective effect of the ALDH2*2 allele increases over the course of adolescence and young adulthood and is modified by the environmental influence of parental alcohol use and misuse.

ALDH2 addiction dependence 21848961 This study aimed to clarify gender differences in the effects of ADH1B and ALDH2 polymorphism on the development of alcohol dependence. ALDH2 drug alcohol 21848961 The onset age of female alcoholics with inactive ALDH2 genotype was significantly lower than those with active ALDH2 genotype, but the onset age did not differ between the inactive and active ALDH2 group in male alcoholics. ALDH2 drug alcohol 21848961 The prevalence of comorbid psychiatric disorders, including major depression, eating disorder, panic disorder, and borderline personality disorder, was significantly higher in female alcoholics with inactive ALDH2 or superactive ADH1B than in those with active ALDH2 or normal ADH1B. ALDH2 drug alcohol 21848961 ALDH2 polymorphism appears to have contrasting effects on the development of alcoholism in women and men.

ALDH2 drug alcohol 21309949 Interaction effects indicated that associations of implicit motives with drinking outcomes were strongest in the context of genetic variants associated with relatively higher risk for alcohol use (COMT Met and ALDH2*1). ALDH2 drug alcohol 21118274 Because aldehyde dehydrogenase 2 (ALDH2) has been shown to have a great impact on the subjective responses to alcohol, we divided subjects by ALDH2 genotype for further analyses. ALDH2 drug alcohol 21118274 Subjects with 1 or 2 copies of the more common allele showed greater subjective responses to alcohol than did individuals homozygous for the alcohol dependence associated allele regardless of ALDH2 genotype.

ALDH2 drug alcohol 21070510 Interaction between ALDH2*1*1 and DRD2/ANKK1 TaqI A1A1 genes may be associated with antisocial personality disorder not co morbid with alcoholism. ALDH2 drug alcohol 21070510 Previous studies on acetaldehyde dehydrogenase 2 (ALDH2) focused on drinking behavior or alcoholism because the ALDH2*2 allele protects against the risk of developing alcoholism. ALDH2 drug alcohol 21070510 The interaction of the ALDH2 gene with neurotransmitters, such as dopamine, is suggested to be related to alcoholism. ALDH2 drug alcohol 20958327 The DNA damage induced by ethanol could be attenuated by alcohol dehydrogenase 1B (ADH1B) or acetaldehyde dehydrogenase 2 (ALDH2) inhibitor, and the mRNA expression levels of ADH1B and ALDH2 were increased markedly by ethanol. ALDH2 drug alcohol 20958327 This study provides direct evidence that ethanol can induce oxidative DNA damage in human peripheral lymphocytes in vitro, and its mechanism may be associated with the metabolism of ethanol by the ADH1B/ALDH2 pathway. ALDH2 drug alcohol 20714161 We develop a pharmacokinetic model describing how genetic variations in ADH1B, ADH1C, ADH7, ALDH2, and TAS2R38 affect consumption behavior, and alcohol and acetaldehyde levels over time in various tissues of individuals with a particular genotype to predict their susceptibility to alcohol dependence.

ALDH2 drug alcohol 20700531 Significant interactions were observed between alcohol and ADH1b (rs1229984) with respect to LDL and between alcohol and ALDH2 (rs886205) with respect to IGT/diabetes. ALDH2 drug alcohol 20652463 Evaluation of a brief web based genetic feedback intervention for reducing alcohol related health risks associated with ALDH2. ALDH2 drug alcohol 20652463 The purpose of this study was to evaluate the feasibility, acceptability, and efficacy of a web based alcohol intervention incorporating genetic feedback and risk information specific to ALDH2 genotype. ALDH2 drug alcohol 20652463 The ALDH2*2 variant is associated with partial protection against alcohol dependence but confers significantly increased risk for alcohol related cancers as a function of alcohol exposure. ALDH2 addiction dependence 20652463 The ALDH2*2 variant is associated with partial protection against alcohol dependence but confers significantly increased risk for alcohol related cancers as a function of alcohol exposure. ALDH2 drug alcohol 20652463 Results provide initial evidence of the feasibility, acceptability, and brief efficacy of web based genetic feedback for reducing alcohol related health risks associated with ALDH2 genotype. ALDH2 drug alcohol 20626721 While the rs1800759 and rs1042364 A A haplotype had a potential protective influence on the risk for several AD related phenotypes, this effect is rather small compared to functional variants of other alcohol or acetaldehyde metabolizing enzymes like ALDH2*2 or ADH1B*2. ALDH2 drug alcohol 20598484 The genetic variation of ADH1B, ALDH2, and CYP2E1 is different among racial populations and cause difference in elimination rates of alcohol. ALDH2 drug alcohol 20598484 This study may be useful in epidemiological studies of the influence of ADH1B, ALDH2, CYP2E1*6, and CYP2E1*7B polymorphisms on diseases, including several types of cancer related to alcohol consumption and alcohol dependence.

ALDH2 addiction dependence 20477771 MAOA interacts with the ALDH2 gene in anxiety depression alcohol dependence. ALDH2 drug alcohol 20178264 About half of northeastern Asians lack ALDH2 (Acetaldehyde Dehydrogenase 2), an enzyme involved in alcohol metabolism. ALDH2 drug alcohol 20178264 People with deficient ALDH2 often experience facial flushing after drinking a small dose of alcohol. ALDH2 drug nicotine 20093384 We conducted a case control study to examine possible interaction between smoking and aldehyde dehydrogenase 2 (ALDH2) Glu504Lys polymorphism (rs671) on the risk of lung cancer in Japanese. ALDH2 drug nicotine 20093384 The impact of smoking, ALDH2 genotype, and their interaction on lung cancer risk were assessed by odds ratio (OR) and 95% confidence interval adjusted for potential confounders. ALDH2 drug nicotine 20093384 Interaction between ALDH2 genotype (Glu/Glu + Glu/Lys versus Lys/Lys) and cumulative smoking dose was statistically significant (P = 0.036) and was consistently observed in the analysis among never drinkers (interaction P = 0.041). ALDH2 drug nicotine 20093384 These results suggest that ALDH2 Lys/Lys, a null enzyme activity genotype, modifies the impact of smoking on the risk of lung cancer. ALDH2 drug alcohol 20077761 The genotype frequencies of the ADH2 and ALDH2 gene polymorphisms as well as the A118G polymorphism of the mu opioid receptor gene (OPRM1) in Korean men and women with alcohol dependence (AD) were compared with those of normal healthy (NH) Korean men and women at a low risk for alcoholism. ALDH2 drug opioid 20077761 The genotype frequencies of the ADH2 and ALDH2 gene polymorphisms as well as the A118G polymorphism of the mu opioid receptor gene (OPRM1) in Korean men and women with alcohol dependence (AD) were compared with those of normal healthy (NH) Korean men and women at a low risk for alcoholism. ALDH2 addiction dependence 20077761 The genotype frequencies of the ADH2 and ALDH2 gene polymorphisms as well as the A118G polymorphism of the mu opioid receptor gene (OPRM1) in Korean men and women with alcohol dependence (AD) were compared with those of normal healthy (NH) Korean men and women at a low risk for alcoholism. ALDH2 drug alcohol 20077761 These results suggest that, while the risk of alcoholism in Korean men is predominantly affected by the presence of the ALDH2 1/1 genotype, the risk of alcoholism in Korean women is primarily associated with the ADH2 1/1 genotype and G carrier genotype of the OPRM1 A118G polymorphism. ALDH2 drug alcohol 20025435 The association between two functional polymorphisms in alcohol dehydrogenase (ADH2/ADH1B) and aldehyde dehydrogenase (ALDH2) genes and alcohol dependence was examined in 182 Chinese and Indian patients undergoing treatment for alcohol dependence and 184 screened control subjects from Singapore. ALDH2 addiction dependence 20025435 The association between two functional polymorphisms in alcohol dehydrogenase (ADH2/ADH1B) and aldehyde dehydrogenase (ALDH2) genes and alcohol dependence was examined in 182 Chinese and Indian patients undergoing treatment for alcohol dependence and 184 screened control subjects from Singapore. ALDH2 drug alcohol 20025435 Our results showed that frequencies of ADH1B*2 and ALDH2*2 were higher in controls compared to alcohol dependent subjects for both Chinese and Indians. ALDH2 drug alcohol 19942091 This study was designed to evaluate the role of facilitated detoxification of acetaldehyde, the main metabolic product of ethanol, through systemic overexpression of mitochondrial aldehyde dehydrogenase 2 (ALDH2) on acute ethanol exposure induced myocardial damage. ALDH2 drug alcohol 19942091 Wild type FVB (friend virus B) and ALDH2 mice were challenged with ethanol (3 g/kg, intraperitoneally), and cardiac function was assessed 24 h later using the Langendroff and cardiomyocyte edge detection systems. ALDH2 drug alcohol 19942091 ALDH2 reduced ethanol induced elevation in cardiac acetaldehyde levels. ALDH2 drug alcohol 19942091 Acute ethanol challenge deteriorated myocardial and cardiomyocyte contractile function evidenced by reduction in maximal velocity of pressure development and decline (+/ dP/dt), left ventricular developed pressure, cell shortening, and prolonged relengthening duration, the effects of which were alleviated by ALDH2. ALDH2 drug alcohol 19942091 Ethanol treatment dampened phosphorylation of Akt and AMPK associated with up regulated PP2A and PP2C, which was abrogated by ALDH2. ALDH2 drug alcohol 19942091 ALDH2 significantly attenuated ethanol induced decrease in Akt and AMPK stimulated phosphorylation of Foxo3 at Thr32 and Ser413, respectively. ALDH2 drug alcohol 19942091 Consistently, ALDH2 rescued ethanol induced myocardial apoptosis, protein damage, and mitochondrial membrane potential depolarization. ALDH2 drug alcohol 19942091 Our results suggest that ALDH2 is cardioprotective against acute ethanol toxicity, possibly through inhibition of protein phosphatases, leading to enhanced Akt and AMPK activation, and subsequently, inhibition of Foxo3, apoptosis, and mitochondrial dysfunction.

ALDH2 drug alcohol 19393179 The alcohol sensitivity in Orientals is due to a delayed oxidation of acetaldehyde by an atypical aldehyde dehydrogenase ALDH2487Lys, which is resulted from a structural mutation in gene ALDH2. ALDH2 drug alcohol 19302089 MAOA uVNTR polymorphism may modify the protective effect of ALDH2 gene against alcohol dependence in antisocial personality disorder. ALDH2 addiction dependence 19302089 MAOA uVNTR polymorphism may modify the protective effect of ALDH2 gene against alcohol dependence in antisocial personality disorder. ALDH2 drug alcohol 19302089 Antisocial alcoholism is related to dopamine and serotonin which are catalyzed by monoamine oxidase A (MAOA) and acetaldehyde dehydrogenase 2 (ALDH2). ALDH2 drug alcohol 19302089 The objective of this study is to determine whether the interaction between the MAOA and the ALDH2 genes is associated with subjects with antisocial personality disorder (ASPD) having alcoholism. ALDH2 drug alcohol 19302089 However, the protective effects of the ALDH2*2 allele against alcoholism might disappear in subjects with ASPD and carrying MAOA uVNTR 4 repeat allele in the Han Chinese male population. ALDH2 drug alcohol 19298328 Association between personality traits and ALDH2 polymorphism in Japanese male alcoholics. ALDH2 drug alcohol 19298328 Alcoholics who have developed alcoholism despite a strong negative risk factor, that is, the inactive form of aldehyde dehydrogenase 2 (ALDH2), are considered advantageous for studying predisposing factors for alcoholism. ALDH2 drug alcohol 19298328 This study aimed to compare personality profiles and clinical characteristics between alcoholics with active and inactive ALDH2. ALDH2 drug alcohol 19298328 Alcoholics with inactive ALDH2 had significantly higher novelty seeking (NS) and lower harm avoidance (HA) scores compared with those with active ALDH2. ALDH2 addiction relapse 19298328 Alcoholics with inactive ALDH2 had significantly higher novelty seeking (NS) and lower harm avoidance (HA) scores compared with those with active ALDH2. ALDH2 drug alcohol 19298328 These results suggest that high NS and low HA scores in alcoholics with inactive ALDH2 are associated with an increased risk for developing alcoholism, despite a low enzymatic ability to eliminate toxic acetaldehyde in these subjects. ALDH2 drug alcohol 19298328 A study of alcoholics with inactive ALDH2 is useful for detecting environmental or personality factors related to alcoholism. ALDH2 drug alcohol 19251111 Liver alcohol dehydrogenase oxidizes ethanol to acetaldehyde, which is further oxidized to acetate by aldehyde dehydrogenase 2 (ALDH2*1). ALDH2 drug alcohol 19251111 Individuals who carry a low activity ALDH2 (ALDH2*2) display high blood acetaldehyde levels after ethanol consumption, which leads to dysphoric effects, such as facial flushing, nausea, dizziness, and headache ("Asian alcohol phenotype"), which result in an aversion to alcohol and protection against alcohol abuse and alcoholism. ALDH2 addiction aversion 19251111 Individuals who carry a low activity ALDH2 (ALDH2*2) display high blood acetaldehyde levels after ethanol consumption, which leads to dysphoric effects, such as facial flushing, nausea, dizziness, and headache ("Asian alcohol phenotype"), which result in an aversion to alcohol and protection against alcohol abuse and alcoholism. ALDH2 drug alcohol 19251111 This study describes chemically synthesized siRNAs and an endogenously synthesized shRNA, which reduce ALDH2 activity and constitute tools that should be of value for further alcohol research. ALDH2 drug alcohol 19014920 Functional variant alleles ADH1B*2 and ALDH2*2 have been consistently replicated to show protection against developing alcohol dependence. ALDH2 addiction dependence 19014920 Functional variant alleles ADH1B*2 and ALDH2*2 have been consistently replicated to show protection against developing alcohol dependence. ALDH2 drug alcohol 19014920 Multiple logistic regression analyses suggest that ADH1B*2 and ALDH2*2 may independently influence the risk for alcoholism. ALDH2 drug alcohol 19014920 It has been well documented that homozygosity of ALDH2*2 almost fully protects against developing alcoholism and that the heterozygosity only affords a partial protection to varying degrees. ALDH2 drug alcohol 19014920 Correlations of blood ethanol and acetaldehyde concentrations, cardiovascular hemodynamic responses, and subjective perceptions have been investigated in men with different combinatorial ADH1B and ALDH2 genotypes following challenge with ethanol for a period of 130 min. ALDH2 drug alcohol 19014920 The pharmacokinetic and pharmacodynamic consequences indicate that acetaldehyde, rather than ethanol, is primarily responsible for the observed alcohol sensitivity reactions, suggesting that the full protection by ALDH2*2/*2 can be ascribed to the intense unpleasant physiological and psychological reactions caused by persistently elevated blood acetaldehyde after ingesting a small amount of alcohol and that the partial protection by ALDH2*1/*2 can be attributed to a faster elimination of acetaldehyde and the lower accumulation in circulation. ALDH2 drug alcohol 19014920 Physiological tolerance or innate insensitivity to acetaldehyde may be crucial for development of alcohol dependence in alcoholics carrying ALDH2*2. ALDH2 addiction dependence 19014920 Physiological tolerance or innate insensitivity to acetaldehyde may be crucial for development of alcohol dependence in alcoholics carrying ALDH2*2.

ALDH2 addiction dependence 18996923 This study tested for associations between nine polymorphisms in ALDH2 and 41 in the seven ADH genes, and alcohol related flushing, alcohol use and dependence symptom scores in 4597 Australian twins. ALDH2 drug alcohol 18996923 ALDH2 variation was not associated with flushing or alcohol consumption, but was weakly associated with AD measures. ALDH2 addiction intoxication 18782342 The ALDH2 promoter variant was associated with binge drinking, and the ALDH1b1 ala69val polymorphism was associated with diastolic blood pressure. ALDH2 drug alcohol 18613661 The ALDH2*2 gene encoding the inactive variant form of mitochondrial aldehyde dehydrogenase (ALDH2) protects nearly all carriers of this gene from alcoholism. ALDH2 drug alcohol 18613661 Inhibition of ALDH2 has hence become a possible strategy to treat alcoholism. ALDH2 drug alcohol 18613661 The natural product 7 O glucosyl 4' hydroxyisoflavone (daidzin), isolated from the kudzu vine (Peruraria lobata), is a specific inhibitor of ALDH2 and suppresses ethanol consumption.

ALDH2 drug alcohol 18299763 The current study examined self report level of response to alcohol, ALDH2 and ADH1B, country of origin, and family history of alcoholism in 154 Chinese and 181 Korean American college students. ALDH2 drug alcohol 18299763 This relationship remained significant after considering the effects of gender, height, weight, quantity and frequency of alcohol consumption (over the previous 90 days), ALDH2 genotype, ADH1B genotype, country of origin, and first degree family history of alcohol dependence. ALDH2 addiction dependence 18299763 This relationship remained significant after considering the effects of gender, height, weight, quantity and frequency of alcohol consumption (over the previous 90 days), ALDH2 genotype, ADH1B genotype, country of origin, and first degree family history of alcohol dependence. ALDH2 drug alcohol 18070247 In line with the above, we have tested if inhibiting the expression of the aldehyde dehydrogenase gene (ALDH2) by an anti Aldh2 antisense gene can curtail the drive of alcohol dependent animals to consume alcohol. ALDH2 drug alcohol 18070247 The single intravenous administration of an anti Aldh2 antisense gene carried by an adenoviral vector reduced liver ALDH2 activity by 85% (p < 0.002) and inhibited voluntary ethanol intake by 50% (ANOVA p < 0.005) for 34 days. ALDH2 drug alcohol 17980785 The guidelines for Disulfiram, an ALDH2 inhibitor, provide a set of guidelines for use with the herb Pueraria lobata. ALDH2 drug alcohol 17980785 The recommendations for its use should be similar to those for the ALDH2 inhibitor, Disulfiram. ALDH2 drug alcohol 17960296 A previous cross sectional study showed that, among individuals of Chinese and Korean descent, possession of ALDH2*2 alleles was associated with protection against alcohol dependence, whereas conduct disorder was associated with increased vulnerability to dependence. ALDH2 addiction dependence 17960296 A previous cross sectional study showed that, among individuals of Chinese and Korean descent, possession of ALDH2*2 alleles was associated with protection against alcohol dependence, whereas conduct disorder was associated with increased vulnerability to dependence. ALDH2 drug alcohol 17960296 The degree of alcohol consumption observed among participants with ALDH2*2 alleles is consistent with previous findings showing that, although their presence may be protective, it does not preclude heavy drinking episodes. ALDH2 drug alcohol 17948892 Due to the documented protective effects against alcoholism of ALDH2*1/*2 or *2/*2 genotype among the Han Chinese population, we recruited antisocial non alcoholics from the Han Chinese population in Taiwan to verify Cloninger's hypotheses. ALDH2 drug alcohol 17885622 Pharmacokinetic and pharmacodynamic basis for partial protection against alcoholism in Asians, heterozygous for the variant ALDH2*2 gene allele. ALDH2 drug alcohol 17885622 It has been well documented that although homozygosity of the variant aldehyde dehydrogenase 2 (ALDH2) gene allele, ALDH2*2, in Asians almost fully protects against alcoholism, the heterozygosity only affords a partial protection to varying degrees. ALDH2 drug alcohol 17885622 The subjects were divided into 3 combinatorial genotypic groups of alcohol dehydrogenase (ADH) and ALDH, that is, ALDH2*1/*1 ADH1B*1/*1 ADH1C*1/*1 (n=8), ALDH2*1/*1 ADH1B*2/*2 ADH1C*1/*1 (n=8), and ALDH2*1/*2 ADH1B*2/*2 ADH1C*1/*1 (n=16). ALDH2 drug alcohol 17885622 Heterozygotic ALDH2*1/*2 subjects were found to be strikingly responsive to the moderate amount of alcohol, as evidenced by the prominent cardiovascular effects as well as subjective perceptions of general discomfort for as long as 2 h following ingestion. ALDH2 drug alcohol 17718397 Variants of three genes encoding alcohol metabolizing enzymes, the aldehyde dehydrogenase gene ALDH2 and the alcohol dehydrogenase genes ADH1B and ADH1C, have been associated with reduced rates of alcohol dependence.

ALDH2 drug alcohol 17673211 We previously reported that mitochondrial ALDH2 could be inactivated via S nitrosylation in ethanol exposed rats. ALDH2 drug alcohol 17488809 Since the release of NADH from the ADH.NADH complex constitutes the rate limiting step of ADH (but not of ALDH2) activity, endogenous NADH oxidizing substrates present at the time of ethanol intake may contribute to the acetaldehyde burst. ALDH2 drug alcohol 17454860 We determined the allele and genotype of ADH2, ADH3 and ALDH2 in 198 subjects: 57 with alcohol cirrhosis, 44 with alcohol chronic pancreatitis and 43 "healthy alcoholics"; 54 healthy non drinkers served as controls. ALDH2 drug alcohol 17454860 Genetic polymorphism of ALDH2 shows no correlation with alcohol addiction or alcohol cirrhosis and alcohol chronic pancreatitis. ALDH2 addiction addiction 17454860 Genetic polymorphism of ALDH2 shows no correlation with alcohol addiction or alcohol cirrhosis and alcohol chronic pancreatitis.

ALDH2 addiction dependence 16822169 Meta analyses were conducted to determine the magnitude of relationships between polymorphisms in 2 genes, ALDH2 and ADH1B, with alcohol dependence in Asians. ALDH2 drug alcohol 16818871 The ALDH2*2 allele has been shown to be a protective factor against alcoholism in a normal population owing in part to the elevated blood level of acetaldehyde and its accompanying physiological discomforts after drinking alcohol. ALDH2 drug alcohol 16818871 Despite the well established link between the ALDH2*2 allele and the physiological discomforts after drinking, very little is known regarding the psychological expectancies of drinking among persons with alcoholism with different ALDH genotypes. ALDH2 drug alcohol 16818871 To determine whether there are differences in craving, alcohol consumption, and alcohol outcome expectancies between persons with alcoholism who have the ALDH2*1/*2 genotype and persons with alcoholism who have the ALDH2*1/*1 genotype. ALDH2 addiction relapse 16818871 To determine whether there are differences in craving, alcohol consumption, and alcohol outcome expectancies between persons with alcoholism who have the ALDH2*1/*2 genotype and persons with alcoholism who have the ALDH2*1/*1 genotype. ALDH2 drug alcohol 16818871 Overall, the ALDH2*1/*2 group had lower negative alcohol outcome expectancies (F(4,93) = 2.43, P < or = .05, eta(p)2 = 0.10). ALDH2 drug alcohol 16818871 Moreover, the ALDH2*1/*2 group had higher positive alcohol outcome expectancies (F(7,90) = 2.36, P < .05, eta(p)2 = 0.16), and they had more expected positive outcomes in the relaxation and tension reduction domain (P < .05). ALDH2 drug alcohol 16818871 Although the ALDH2*2 allele has been associated with negative physiological responses in normal samples in past research, the psychological expectancies of drinking are more positive and less negative for persons with alcoholism who have the ALDH2*1/*2 genotype.

ALDH2 addiction dependence 16792555 The low activity variant of the aldehyde dehydrogenase 2 (ALDH2) gene found in East Asian populations leads to the alcohol flush reaction and reduces alcohol consumption and risk of alcohol dependence (AD). ALDH2 drug alcohol 16792555 Haplotypes based on 5 single nucleotide polymorphisms (SNPs) were used in tests of the effects of variation in the ALDH2 gene on alcohol metabolism and alcohol's effects. ALDH2 drug alcohol 16792555 Significant effects of ALDH2 haplotype were observed for breath alcohol concentration, with similar but smaller and nonsignificant effects on blood alcohol.

ALDH2 drug alcohol 16679777 We also genotyped a polymorphism, G1510A, in the acetaldehyde dehydrogenase 2 gene (ALDH2), in which the A allele causes poor metabolism of acetaldehyde, a major metabolite of alcohol. ALDH2 drug alcohol 16679777 Both OPRM1 118G and ALDH2 1510G were significantly associated with alcohol dependence. ALDH2 addiction dependence 16679777 Both OPRM1 118G and ALDH2 1510G were significantly associated with alcohol dependence. ALDH2 drug alcohol 16679777 These results suggest that OPRM1 118G in addition to ALDH2 1510G might be one of the risk factors for alcohol dependence in Japanese people.

ALDH2 drug alcohol 21432367 The subjects were 264 men aged 39 to 80 years who were classified into the ALDH2 deficiency or sufficiency group using the ethanol patch test and the Tokyo University ALDH2 Phenotype Screening Test. ALDH2 drug nicotine 21432367 Blood pressure and the levels of biochemical markers in groups with ALDH2 sufficiency, ALDH2 deficiency and drinking habit were compared using multiple regression models for adjusting age, smoking habit, physical exercising habit and body mass index. ALDH2 drug alcohol 21432367 The levels of serum high density lipoprotein cholesterol, triglycerides, aspartate aminotransferase (AST) and gamma glutamyl transpeptidase (γ GTP) were significantly higher in current drinkers of 20 g of ethanol or more per day than in nondrinkers of the ALDH2 sufficiency group. ALDH2 drug alcohol 21432367 The levels of serum AST and γ GTP in current drinkers of 20 g of ethanol or more per day, and fasting blood sugar in current drinkers of less than 20 g of ethanol per day were significantly higher than those in nondrinkers of the ALDH2 deficiency group. ALDH2 drug alcohol 21432367 These results suggest that alcohol consumption increases the levels of serum lipids and liver enzymes in ALDH2 sufficient individuals and liver enzymes and blood glucose levels in ALDH2 deficient individuals. ALDH2 drug alcohol 16440674 We analyzed the Kurihama Alcoholism Screening Test (KAST), the Adolescent Alcohol Involvement Scale (AAIS), the Fagerstroem Tolerance Questionnaire (FTQ), the Tokyo University ALDH2 Phenotype Screening Test (TAST), results of ethanol patch tests, the presence or absence of a smoking habit, and gender by "Hayashi's quantification theory, type II" in 415 senior students (232 males and 183 females) of a dental college between 2000 and 2003, and evaluated their relationships.

ALDH2 drug alcohol 16404797 Data are consistent with the hypothesis that elevations in acetaldehyde, increased sensitivity to alcohol, and lower levels of drinking reflect the mechanism by which the ALDH2*2 allele reduces risk for alcohol dependence.

ALDH2 drug alcohol 16131845 Data presented show that antialcohol drugs that inhibit Aldh2 gene expression can be generated endogenously in liver cells infected by an adenoviral vector carrying an antisense coding gene, thus mimicking the high acetaldehyde phenotype that exists in humans carrying the Glu487Lys mutation who are protected against alcoholism. ALDH2 drug alcohol 16125912 One hundred and eleven male patients with alcohol dependence and 123 nonalcoholic healthy men were tested for the genetic polymorphisms of alcohol dehydrogenase 2 (ADH2), aldehyde dehydrogenase 2 (ALDH2), serotonin transporter (5 HTT) and dopamine transporter (DAT1). ALDH2 addiction dependence 16125912 One hundred and eleven male patients with alcohol dependence and 123 nonalcoholic healthy men were tested for the genetic polymorphisms of alcohol dehydrogenase 2 (ADH2), aldehyde dehydrogenase 2 (ALDH2), serotonin transporter (5 HTT) and dopamine transporter (DAT1). ALDH2 drug alcohol 16125912 Genotype and allele frequencies of ALDH2 G1951A SNP in familial or non familial alcoholic patients differ from normal controls. ALDH2 drug alcohol 16046871 Associations between hangover and ALDH2 genotype, alcohol flushing, and MCV were examined for 251 Japanese workers (139 men, 112 women). ALDH2 drug alcohol 16046871 Inactive ALDH2*1/2*2 heterozygotes drank less alcohol than active ALDH2*1/2*1 homozygotes (p < 0.0001), but the frequency of hangover did not significantly differ between the two groups for either gender. ALDH2 drug alcohol 16046871 The proportion of men who had hangover three times or more during the past year increased significantly with increased daily alcohol consumption in men with the ALDH2*1/2*2 genotype (p = 0.0002) but not in those with the ALDH2*1/2*1 genotype. ALDH2 drug alcohol 16046871 For men who usually consumed <44 g of ethanol/day, the median amount of drinking before hangover was significantly lower for ALDH2*1/2*2 men than for ALDH2*1/2*1 men reporting the same level of consumption. ALDH2 drug alcohol 16046871 Inactive heterozygous ALDH2, alcohol flushing, and increased MCV were positively associated with hangover susceptibility in Japanese workers, suggesting that acetaldehyde is etiologically linked to the development of hangover. ALDH2 drug alcohol 15957670 Associations of ALDH2 and ADH1B genotypes with response to alcohol in Asian Americans. ALDH2 drug alcohol 15957670 Individuals with alcohol dependence are less likely to possess variant alleles of the alcohol metabolizing genes, aldehyde dehydrogenase (ALDH2*2) and alcohol dehydrogenase (ADH1B*2), than non alcohol dependent controls. ALDH2 addiction dependence 15957670 Individuals with alcohol dependence are less likely to possess variant alleles of the alcohol metabolizing genes, aldehyde dehydrogenase (ALDH2*2) and alcohol dehydrogenase (ADH1B*2), than non alcohol dependent controls. ALDH2 drug alcohol 15957670 Previous research has shown that individuals with ALDH2*2 demonstrate enhanced reactions to alcohol compared with those without this genetic variant, but evidence that ADH1B*2 is associated with a greater alcohol response is mixed. ALDH2 drug alcohol 15957670 This study was designed to determine whether the ADH1B genotype is associated with more intense reactions to alcohol after controlling for the ALDH2 genotype. ALDH2 drug alcohol 15957670 Participants with the ALDH2*1/*2 and ALDH2*2/*2 genotypes were more likely to experience vomiting following ingestion of the alcohol beverage than those with the ALDH2*1/*1 genotype. ALDH2 drug alcohol 15957670 Participants with the ALDH2*1/*2 genotype also had greater pulse rate increases, observed flushing ratings, and subjective feelings of intoxication 30 minutes after ingestion of alcohol than participants with the ALDH2*1/*1 genotype, despite equivalent blood alcohol concentration (BAC) measurements. ALDH2 addiction intoxication 15957670 Participants with the ALDH2*1/*2 genotype also had greater pulse rate increases, observed flushing ratings, and subjective feelings of intoxication 30 minutes after ingestion of alcohol than participants with the ALDH2*1/*1 genotype, despite equivalent blood alcohol concentration (BAC) measurements. ALDH2 drug alcohol 15957670 Among participants with the ALDH2*1/*1 genotype, there were no additional effects of the ADH1B genotype on any measures of response to alcohol. ALDH2 drug alcohol 15957670 Among participants with the ALDH2*1/*2 genotype, those with the ADH1B*2/*2 genotype were more likely to experience alcohol induced vomiting and to report feeling less "great overall" 30 minutes after ingestion of alcohol than those with the ADH1B*1/*2 genotype. ALDH2 drug alcohol 15957670 These findings are consistent with the hypothesis that there is an additional effect of ADH1B*2 on level of response to alcohol, but only among individuals with the ALDH2*1/*2 genotype. ALDH2 drug alcohol 15900217 Polymorphisms in the mitochondrial aldehyde dehydrogenase gene (Aldh2) determine peak blood acetaldehyde levels and voluntary ethanol consumption in rats. ALDH2 drug alcohol 15900217 Wistar derived rats selectively bred as low alcohol consumers for many generations present an allele (Aldh2(2)) of mitochondrial aldehyde dehydrogenase that does not exist in high alcohol consumers, which mostly carry the Aldh2(1) allele. ALDH2 drug alcohol 15900217 Data show that, with a mixed genetic background, F2 Aldh2(1)/Aldh2(1) rats voluntarily consume 65% more alcohol (P<0.01) than F2 Aldh2(2)/Aldh2(2) rats. ALDH2 drug alcohol 15900217 A major phenotypic difference was a five fold higher (P<0.0025) peak blood acetaldehyde level following ethanol administration in the lower drinker F2 Aldh2(2)/Aldh2(2) compared to the higher drinker F2 Aldh2(1)/Aldh2(1) animals, despite the existence of identical steady state levels of blood acetaldehyde in animals of both genotypes. ALDH2 drug alcohol 15900217 Polymorphisms in Aldh2 play an important role in: (i) determining peak blood acetaldehyde levels and (ii) modulating voluntary ethanol consumption. ALDH2 drug alcohol 15900217 We postulate that the markedly higher peak of blood acetaldehyde generated in Aldh2(2)/Aldh2(2)(2) animals is aversive, leading to a reduced alcohol intake in Aldh2(2)/Aldh2(2) versus that in Aldh2(1)/Aldh2(1) animals. ALDH2 addiction aversion 15900217 We postulate that the markedly higher peak of blood acetaldehyde generated in Aldh2(2)/Aldh2(2)(2) animals is aversive, leading to a reduced alcohol intake in Aldh2(2)/Aldh2(2) versus that in Aldh2(1)/Aldh2(1) animals. ALDH2 drug alcohol 15863807 The authors examined the genetic polymorphisms of alcohol dehydrogenase 2 and 3 (ADH2 and ADH3) and aldehyde dehydrogenase (ALDH2) in patients diagnosed as having Cloninger's type I or type II alcoholism. ALDH2 drug alcohol 15863807 Seventy two alcoholic men and 38 nonalcoholic, healthy men were tested for the distribution of genotypes and alleles of ADH2, ADH3, and ALDH2. ALDH2 drug alcohol 15863807 The frequency of the ALDH2*1 allele was significantly higher in men with alcohol dependence than in healthy men.

ALDH2 drug alcohol 15542751 Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase 2 (ALDH2) play central roles in the metabolism of ethanol and its metabolite, acetaldehyde, in the liver. ALDH2 drug alcohol 15542751 The results revealed that (1) the less active allele of the ADH2 gene (ADH2*1) is associated with an increased risk for alcohol dependence, alcohol induced persistent amnestic disorder, alcohol withdrawal syndrome, and cancer of the upper GI tract; (2) the inactive allele of the ALDH2 gene (ALDH2*2) is associated with a decreased risk for alcohol dependence, and an increased risk for alcoholic polyneuropathy and cancer in the same region; and (3) these genetic variations modify clinical features of alcohol dependence.

ALDH2 drug alcohol 15112932 Mr. Cook's and Dr. Wall's paper adds another dimension to this article by presenting research on both the aldehyde dehydrogenase (ALDH2) and alcohol dehydrogenase (ADH2) genetic variants and their association with the alcohol related flushing response that is prevalent in Asian populations. ALDH2 drug alcohol 15084894 In the Han Chinese population, the alcohol dehydrogenase 1B*2/*2 (ADH1B*2/*2) genotype and the aldehyde dehydrogenase 2*2 (ALDH2*2) allele have been considered as protective factors against alcohol abuse or dependence.

ALDH2 drug alcohol 15084894 We hypothesized that the ADH1B and ALDH2 genes might interact with the DRD2 gene and that the association between the DRD2 gene and alcohol dependence might be affected by different ADH1B and ALDH2 genotypes. ALDH2 addiction dependence 15084894 We hypothesized that the ADH1B and ALDH2 genes might interact with the DRD2 gene and that the association between the DRD2 gene and alcohol dependence might be affected by different ADH1B and ALDH2 genotypes. ALDH2 drug alcohol 15066702 Mexican Americans have a low frequency of the protective alleles ADH1B(*)2 and ALDH2(*)2 and a relatively high frequency of CYP2E1 c2, which is associated with early onset alcoholism. ALDH2 drug alcohol 15041893 Among the multiple factors which influence these variations, genetic factors especially those related to the different alleles of ADH2 and ALDH2, are the most well known and are related to the development of alcohol dependence, particularly in some populations such as those of Asian origin.

ALDH2 drug alcohol 14691070 We excluded subjects with inactive ALDH2 and employed the subjects with ALDH2*1/2*1 (384 alcoholics and 792 controls). ALDH2 addiction aversion 14690875 ), which were not associated with the line difference detected in blood AcH levels, the present study examined the contribution of brain ALDH2 activity to AcH aversion in UChA and UChB rats. ALDH2 addiction aversion 14690875 In experiment 2, the possibility that the inhibition of the brain ALDH2 would lower the AcH aversion threshold in both lines was studied by determining the effect of cyanamide (10 mg/kg i.p.) ALDH2 addiction aversion 14690875 pretreatment, an inhibitor of ALDH, on AcH aversion, blood AcH levels and brain ALDH2 activity. ALDH2 addiction aversion 14690875 The finding that blocking the brain ALDH2 (52%) by cyanamide can make a non aversive dose of AcH (25 mg/kg) aversive to UChA and UChB rats at blood AcH levels comparable to those induced by a non aversive dose of AcH (100 mg/kg) in control UChB rats indicates that the line difference in AcH aversion is associated more with brain ALDH2 activity than with liver ALDH2 activity. ALDH2 drug alcohol 14615012 The objective of the current study was to compare the effect of an intraperitoneal dose of acetaldehyde (50 mg/kg) in high alcohol drinking (UChB) and low alcohol drinking (UChA) rat lines, which differ in the activity of the brain mitochondrial class 2 aldehyde dehydrogenase (ALDH2) as a consequence of differences in their ALDH2 genotypes.

ALDH2 drug alcohol 12884000 Specifically, ADH1B*47His (previously ADH2 2) and ALDH2 2 have been shown to confer protection against alcoholism, presumably through accumulation of acetaldehyde in the blood and a resultant 'flushing response' to alcohol consumption. ALDH2 drug alcohol 12884000 In the current study, variants at ADH1B (previously ADH2), ADH1C (previously ADH3), and ALDH2 were assayed in DNA extracts from participants belonging to a Southwest American Indian tribe (n=490) with a high prevalence of alcoholism. ALDH2 drug alcohol 12824808 In Taiwan, about 70% of the Han Chinese population have the ADH2*2 allele and 50% show ALDH2*1/*2 or ALDH2*2/*2 genotypes, which offer protection against drinking behavior and the risk of developing alcoholism. ALDH2 drug alcohol 12759156 The drinking behavior, alcohol induced facial flushing and ALDH2 genotypes were determined in 283 Thai men comprising 85 who were alcohol dependent, 62 hazardous/harmful drinkers and 136 non drinkers or infrequent drinkers. ALDH2 drug alcohol 12759156 The risks of being alcohol dependent and of having hazardous/harmful drinking were lower in individuals with heterozygous ALDH2*1/*2, compared with homozygous ALDH2*1/*1 [relative probability ratios (95% CI) 0.14 (0.05 0.41) and 0.23 (0.08 0.61), respectively]. ALDH2 drug alcohol 12759156 Eighty percent of those who were heterozygous and 28% of those who were homozygous ALDH2*1 reported flush symptoms after drinking alcohol. ALDH2 drug alcohol 12759156 Similarly, higher percentages of people drinking beyond the safety limit (>60 g/day) and having alcohol related problems were observed in homozygous ALDH2*1 compared with heterozygous individuals: 32% vs. 5% and 27% vs. 12%, respectively. ALDH2 drug alcohol 12759156 Overall, the study supports the role of the mutant ALDH2*2 allele in preventing high alcohol consumption and the development of alcohol dependence in a Thai population.

ALDH2 drug alcohol 12710951 The allele frequency of ADH2*2 (4.3%) and ALDH2*2 (0%), which are considered as protective alleles against alcohol drinking, is very low in Mexican Americans and no association is found between these alleles and alcohol dependence.

ALDH2 drug alcohol 12007581 We have previously found the existence of a relation between activity of the brain mitochondrial aldehyde dehydrogenase (ALDH2) and consumption of ethanol in rats of the low alcohol drinking (UChA) and the high alcohol drinking (UChB) strains. ALDH2 drug alcohol 11956970 The use of persons who become alcoholic despite having a well defined negative risk for alcoholism (inactive aldehyde dehydrogenase 2 or ALDH2) is advantageous in genetic research because of this population's reduced heterogeneity and possible genetic factors conferring susceptibility to alcohol dependence.

ALDH2 drug alcohol 11956970 This investigation of central serotonin neurotransmission, specifically the serotonin 1B (5HT1B) receptor gene and its role in both regulating alcohol consumption and developing alcohol dependence revealed overrepresentation of the C allele of the 861G > C polymorphism of 5HT1B in alcoholics with inactive ALDH2, compared with its frequency in nonalcoholic controls. ALDH2 addiction dependence 11956970 This investigation of central serotonin neurotransmission, specifically the serotonin 1B (5HT1B) receptor gene and its role in both regulating alcohol consumption and developing alcohol dependence revealed overrepresentation of the C allele of the 861G > C polymorphism of 5HT1B in alcoholics with inactive ALDH2, compared with its frequency in nonalcoholic controls. ALDH2 drug alcohol 11956970 No significant differences in 5HT1B genotype and allele distributions were observed between alcoholics with active ALDH2 and controls, however.

ALDH2 addiction dependence 11925062 Previous studies have shown that Asians who possess a variant aldehyde dehydrogenase allele (ALDH2*2) have lower rates of alcohol consumption and dependence. ALDH2 drug alcohol 11925062 Research in Asian men has shown that those with ALDH2*2 have greater responses to alcohol than do those without this genetic variant. ALDH2 drug alcohol 11925062 The present study was designed to determine whether similar levels of response to alcohol, using objective and subjective measurements, are seen in men and women with different ALDH2 genotypes. ALDH2 drug alcohol 11925062 Men and women with ALDH2*1/*2 had greater pulse rate increases, greater observed flushing responses and greater subjective feelings of being dizzy, drunk and high compared with ALDH2*1/*1 participants, despite having equivalent breath alcohol concentrations. ALDH2 addiction intoxication 11925062 ALDH2*1/*2 participants also reported being less likely to drive, following this level of intoxication, compared with ALDH2*1/*1 participants. ALDH2 drug alcohol 11925062 This study suggests that low risk for alcoholism based on possession of an ALDH2*2 allele relates to greater response to alcohol in both men and women. ALDH2 addiction intoxication 11767261 Studies of Asian college students have found that rates of binge drinking are associated with variation in the aldehyde dehydrogenase (ALDH2) gene. ALDH2 drug alcohol 11767261 Chinese and Koreans have different prevalence rates of the ALDH2*2 allele, alcohol use, and alcoholism. ALDH2 addiction intoxication 11767261 The association of ALDH2 status and ethnic group with binge drinking was examined in 328 Chinese, Korean, and White college students. ALDH2 addiction intoxication 11767261 Among Asian participants, ALDH2 status and ethnicity related to binge drinking in an additive manner. ALDH2 addiction intoxication 11767261 Possessing an ALDH2*2 allele and being Chinese were protective factors, and being White and being Korean without an ALDH2*2 allele were risk factors for binge drinking. ALDH2 addiction intoxication 11767261 These results suggest that ALDH2 status, as well as other factors that differ in Koreans and Chinese, but do not interact with ALDH2, are associated with binge drinking among Asians. ALDH2 drug alcohol 11545539 In Asians, variation in the alcohol dehydrogenase (ADH2) gene relates to alcohol dependence, alcohol consumption, and reported alcohol related symptoms, even after controlling for variation in the aldehyde dehydrogenase (ALDH2) gene. ALDH2 addiction dependence 11545539 In Asians, variation in the alcohol dehydrogenase (ADH2) gene relates to alcohol dependence, alcohol consumption, and reported alcohol related symptoms, even after controlling for variation in the aldehyde dehydrogenase (ALDH2) gene. ALDH2 drug alcohol 11535626 A mutation in the gene encoding for the liver mitochondrial aldehyde dehydrogenase (ALDH2 2), present in some Asian populations, lowers or abolishes the activity of this enzyme and results in elevations in blood acetaldehyde upon ethanol consumption, a phenotype that greatly protects against alcohol abuse and alcoholism. ALDH2 drug alcohol 11535626 Administration of ASO 9 (20 mg/kg/day for 4 d) to rats resulted in a 50% reduction in liver ALDH2 mRNA, a 40% inhibition in ALDH2 activity, and a fourfold (P < 0.001) increase in circulating plasma acetaldehyde levels after ethanol (1 g/kg) administration. ALDH2 drug alcohol 11398342 Mitochondrial ALDH2 is a major enzyme in the oxidation of acetaldehyde derived from ethanol metabolism. ALDH2 drug alcohol 11398342 The catalytic deficiency of ALDH2 isozyme is responsible for flushing and other vasomotor symptoms caused by higher acetaldehyde levels after alcohol intake. ALDH2 drug alcohol 11398342 Individuals deficient in ALDH2 activity refrain from excessive drinking of alcohol due to the aversive reactions, leading to protection against alcoholism. ALDH2 addiction aversion 11398342 Individuals deficient in ALDH2 activity refrain from excessive drinking of alcohol due to the aversive reactions, leading to protection against alcoholism.

ALDH2 drug alcohol 11261392 To investigate the association of ALDH2 with the development of drug involvement, the authors analyzed retrospective information about the onset and regular use of alcohol and other substances as reported by 180 Asian American college students. ALDH2 drug alcohol 11261392 Possession of an ALDH2*2 allele was not related to initiation of alcohol use or having ever been intoxicated, but individuals with ALDH2*2 alleles were less likely to be regular drinkers, were less likely to have engaged in a binge drinking episode, reported a lower number of maximum drinks consumed in a 24 hr period, and were less likely to have used tobacco regularly than those without this genetic variant. ALDH2 drug nicotine 11261392 Possession of an ALDH2*2 allele was not related to initiation of alcohol use or having ever been intoxicated, but individuals with ALDH2*2 alleles were less likely to be regular drinkers, were less likely to have engaged in a binge drinking episode, reported a lower number of maximum drinks consumed in a 24 hr period, and were less likely to have used tobacco regularly than those without this genetic variant. ALDH2 addiction intoxication 11261392 Possession of an ALDH2*2 allele was not related to initiation of alcohol use or having ever been intoxicated, but individuals with ALDH2*2 alleles were less likely to be regular drinkers, were less likely to have engaged in a binge drinking episode, reported a lower number of maximum drinks consumed in a 24 hr period, and were less likely to have used tobacco regularly than those without this genetic variant. ALDH2 drug alcohol 11261392 These findings suggest that ALDH2 is associated with the development of not only alcohol related behavior but other substance use behavior as well. ALDH2 drug alcohol 10954050 Dipole estimation of alpha EEG during alcohol ingestion in males genotypes for ALDH2. ALDH2 drug alcohol 10954050 Using a dipole tracing method based on the two dipole model, the purpose of the present study was to investigate alcohol induced changes in the alpha band of electroencephalogram (EEG) and its equivalent current dipoles (ECDs) in 12 healthy male volunteers, who were genetically typed for mitochondrial aldehyde dehydrogenase 2 (ALDH2). ALDH2 drug alcohol 10954050 The difference in the time course was discussed from the viewpoint of the protective effect of ALDH2*2 allele against the risk for alcoholism.

ALDH2 addiction intoxication 10940605 Fatal acute alcohol intoxication in an ALDH2 heterozygote: a case report. ALDH2 drug alcohol 10940605 Those who possess the ALDH2*2 gene show high concentrations of acetaldehyde (AcH) at even comparatively lower alcohol levels. ALDH2 drug alcohol 10630602 Alcohol metabolism and cardiovascular response in an alcoholic patient homozygous for the ALDH2*2 variant gene allele. ALDH2 drug alcohol 10630602 Homozygosity of the variant ALDH2*2 allele previously was believed to fully protect East Asian populations against the development of alcoholism. ALDH2 drug alcohol 10630602 An alcohol dependent patient was identified to be ALDH2*2/*2, ADH2*2/*2, and ADH3*1/*2. ALDH2 drug alcohol 10630602 During 130 min postingestion, the patient generally displayed similar or even less intense cardiovascular hemodynamic alterations when compared to a previously published study of nonalcoholic individuals with ALDH2*2/*2 who had received a lower dose of ethanol (0.2 g/kg). ALDH2 drug alcohol 10630602 Logistic regression analysis of the combinatorial genotypes of ADH2 and ALDH2 in 420 alcohol dependent and 689 nonalcohol dependent subjects indicated that risk for alcoholism was 100 fold lower for the ADH2*2/*2 ALDH2*2/*2 individuals than the ADH2*1/*1 ALDH2*1/*1 individuals. ALDH2 drug alcohol 10630602 The gene status of ALDH2*2/*2 alone can tremendously but not completely (as thought previously) protect against development of alcohol dependence. ALDH2 addiction dependence 10630602 The gene status of ALDH2*2/*2 alone can tremendously but not completely (as thought previously) protect against development of alcohol dependence. ALDH2 drug alcohol 10630602 Physiological tolerance or innate insensitivity to the accumulation of blood acetaldehyde following alcohol ingestion may be crucial for the development of alcoholism in individuals homozygous for ALDH2*2. ALDH2 drug alcohol 10513990 Liver mitochondrial low Km aldehyde dehydrogenase (ALDH2, EC 1.2.1.3), the isoform responsible for the conversion of acetaldehyde to acetate, is inhibited by the sulfoxide bioactivation products of Et2NC(O)SMe (from the alcohol aversion drug disulfiram), Pr2NC(O)SEt (the herbicide S ethyl N,N dipropylthiocarbamate), and BuNHC(O)SMe (from the fungicide benomyl).

ALDH2 drug alcohol 10397292 Self reported alcohol associated symptoms and drinking behavior in three ALDH2 genotypes among Japanese university students. ALDH2 drug alcohol 10397292 Nearly half of the Japanese population is sensitive to alcohol due to a genetic polymorphism in low K(m) aldehyde dehydrogenase (ALDH2). ALDH2 drug alcohol 10397292 In the present study, we investigated the effects of the ALDH2 genotype on both self reported alcohol associated symptoms and alcohol drinking behavior among Japanese university students. ALDH2 drug alcohol 10397292 The frequency of alcohol associated symptoms generally increased in the order ALDH2*1/*1, ALDH2*1/*2, ALDH2*2/*2 among males. ALDH2 drug alcohol 10397292 Mean amounts of alcohol consumption per occasion in the three ALDH2 genotypes stratified by drinking frequency generally increased significantly in the order ALDH2*2/*2, ALDH2*1/*2, ALDH2*1/*1 in both sexes. ALDH2 drug alcohol 10397292 The proportion of binge drinkers defined by those who drink ethanol of > or = 75 ml per occasion on average also increased in the order ALDH2*2/*2 (0.0%), ALDH2*1/*2 (9.8%), ALDH2*1/*1 (22.1%) among male drinkers (> or = 1 day/month). ALDH2 addiction intoxication 10397292 The proportion of binge drinkers defined by those who drink ethanol of > or = 75 ml per occasion on average also increased in the order ALDH2*2/*2 (0.0%), ALDH2*1/*2 (9.8%), ALDH2*1/*1 (22.1%) among male drinkers (> or = 1 day/month). ALDH2 drug alcohol 10397292 We for the first time demonstrated clear associations between the ALDH2 genotype, self reported alcohol associated symptoms, and alcohol drinking behavior among Japanese university students. ALDH2 drug alcohol 10355247 [Relationship between ALDH2 genotypes and choice of alcoholic beverages]. ALDH2 drug alcohol 10355247 It has been shown that around half of Japanese show a marked sensitivity to alcoholic beverages because of aversive reactions due to a catalytic deficiency in ALDH2 isozyme. ALDH2 addiction aversion 10355247 It has been shown that around half of Japanese show a marked sensitivity to alcoholic beverages because of aversive reactions due to a catalytic deficiency in ALDH2 isozyme. ALDH2 drug alcohol 10355247 Therefore, differences in ALDH2 genotypes may possibly influence the choice of alcoholic beverages because the individuals possessing the ALDH2*2 gene may prefer the alcoholic beverages containing lower concentrations of alcohol. ALDH2 drug alcohol 10355247 A large population survey (320 males, 132 females) was conducted using questionnaires to investigate the relationship between ALDH2 genotypes and the choice of alcoholic beverages. ALDH2 drug alcohol 10355247 Individuals with the homozygote of ALDH2*1 generally showed more preference for alcoholic beverages containing a higher concentration of alcohol than those with the heterozygote or the homozygote of ALDH2*2. ALDH2 drug alcohol 10355247 Our data suggested that individuals with ALDH2*2 prefer beverages with lower concentrations of alcohol due to an aversive reaction after drinking, and that there are obvious gender differences in the consumption as well as the choice for many alcoholic beverages. ALDH2 addiction aversion 10355247 Our data suggested that individuals with ALDH2*2 prefer beverages with lower concentrations of alcohol due to an aversive reaction after drinking, and that there are obvious gender differences in the consumption as well as the choice for many alcoholic beverages. ALDH2 drug alcohol 10235293 The different genotypes at the genes encoding the enzymes involved in alcohol metabolism, class one alcohol dehydrogenase (ADH2 and ADH3) and mitochondrial aldehyde dehydrogenase (ALDH2), have previously been shown to confer different predispositions to the development of alcoholism in Chinese Han males (Thomasson et al., 1991; Chen WJ et al., 1996; Chen CC et al., unpublished data). ALDH2 drug alcohol 10235293 Therefore, association studies of alcoholism in Chinese Han might be more sensitive if controlled for the genotypes of ADH2,ADH3, and ALDH2, when other loci, such as DRD2, are examined. ALDH2 drug alcohol 10235293 Several different stratifications by ADH and ALDH2 genotypes were examined; no genotypes or haplotypes at DRD2 differ between alcoholics and nonalcoholics except for a small number of nominally significant p values which do not constitute significant results given the many tests done, some of which are not independent of one another due to linkage disequilibrium. ALDH2 drug alcohol 10235293 These tests included considering the high risk (ADH2*1/*1; *1/*2; ADH3*1/*2; *2/*2; and ALDH2*1/*1) and the low risk (ADH2*2/*2; ADH3*1/*1; and ALDH2*1/*2; *2/*2) groups of alcoholics, as well as nonalcoholic controls. ALDH2 drug alcohol 10235293 After stratification by the relevant genotypes of ADH2, ADH3, and ALDH2 no significant association exists between the genetic variants at the DRD2 locus and alcoholism in the Chinese Han population. ALDH2 drug alcohol 10089015 Approximately 10% of Japanese alcoholics develop their disease despite having an inactive form of aldehyde dehydrogenase 2 (ALDH2), known as a genetic deterrent of heavy drinking due to adverse reactions after drinking. ALDH2 drug alcohol 10089015 Examination of the 1438 A/G polymorphism of the serotonin 2A (5HT2A) receptor gene in 225 Japanese alcoholics with inactive ALDH2 revealed the presence of significantly more of the G allele than was found in 361 control subjects. ALDH2 drug alcohol 10089015 The frequency of the G allele in 282 alcoholics with active ALDH2 fell between the G allele frequencies of controls and subjects with inactive ALDH2. ALDH2 drug alcohol 9862807 The relative sizes of the tunnels also suggest why the bulky alcohol aversive drug disulfiram reacts more rapidly with ALDH1 than ALDH2. ALDH2 addiction aversion 9862807 The relative sizes of the tunnels also suggest why the bulky alcohol aversive drug disulfiram reacts more rapidly with ALDH1 than ALDH2. ALDH2 drug alcohol 9802521 This high alcohol sensitivity among Orientals has been attributed to a highly prevalent polymorphism in low Km aldehyde dehydrogenase (ALDH2). ALDH2 drug alcohol 9802521 In the present study, we attempted to develop a reliable questionnaire method to probe the frequency of alcohol drinking related symptoms to estimate the ALDH2 genotype. ALDH2 drug alcohol 9752691 2) The percentage of active ALDH2 was significantly higher in patients with alcohol tolerance than that in those without it (38%). ALDH2 drug alcohol 9752691 3) The estimated amount of alcohol consumption in the past was 506 +/ 720 g/week in the active ALDH2 group, and 156 +/ 288 g/week in the inactive ALDH2 group, showing a significant difference between the two groups. ALDH2 addiction relapse 9752691 However, salt and water craving in dialysis patients may be influenced partially by an active ALDH2 gene. ALDH2 drug alcohol 26734919 In recent studies involving DNA analysis, it was found that a deficiency of the ALDH2 isozyme (ALDH2*2) was responsible for the flushing symptoms as well as other vasomotor symptoms caused by a higher acetaldehyde level after alcohol consumption. ALDH2 drug alcohol 26734919 Deficiency of ALDH2 activity has been found prevalently only among people of Mongoloid origin, and the deficiency of ALDH2 prevents them from developing alcohol dependence due to the unpleasant physical effects of the flushing symptom. ALDH2 addiction dependence 26734919 Deficiency of ALDH2 activity has been found prevalently only among people of Mongoloid origin, and the deficiency of ALDH2 prevents them from developing alcohol dependence due to the unpleasant physical effects of the flushing symptom. ALDH2 drug alcohol 26734919 It was reported that Mongoloids such as Japanese and Chinese people carry the enzymatically active (ALDH2*1) subunit and/or the inactive (ALDH2*2) one, and that a low proportion of ALDH2 deficiency (ALDH2*2 allele frequency) was found in alcoholics compared with healthy controls. ALDH2 drug alcohol 26734919 It was also reported that polymorphism of ALDH2 and/or CYP2E1 may be associated with the susceptibility to alcohol induced liver injury. ALDH2 drug alcohol 26734919 Concerning blood ethanol elimination kinetics, it was reported that the c2 gene of CYP2E1 and the ALDH2*1 gene may have greater effects on ethanol and acetaldehyde elimination than the other genotypes, when the blood ethanol level is below 20 m M. ALDH2 drug alcohol 9605433 S Methyl N,N diethylthiocarbamate (MeDTC) sulfoxide, a potent inhibitor of the target enzyme mitochondrial aldehyde dehydrogenase (ALDH2), is thought to be the principal active metabolite of disulfiram in vivo. ALDH2 drug alcohol 9605433 We examined the effects on recombinant human ALDH2 of two intermediate metabolites of disulfiram, S methyl N,N diethyldithiocarbamate (MeDDC) sulfoxide and MeDDC sulfine. ALDH2 drug alcohol 9605433 Our results suggest that these newer intermediate metabolites of disulfiram, especially the more potent MeDTC sulfoxide, have the potential to inhibit the target enzyme ALDH2 in patients receiving disulfiram. ALDH2 drug alcohol 9514293 Multiple logistic regression analysis revealed significant contributions by levels of alcohol consumption, the ALDH2 genotype, and daily hassles to the prevalence of those with a high KAST score. ALDH2 drug alcohol 9514293 When we analyzed the data for each ALDH2 genotype, heavier alcohol consumption (> or =28.8 ml/day), older age (> or =40 years old), and very high daily hassles levels (> or =20) significantly increased the prevalence of problem drinkers in ALDH2*1/*1. ALDH2 drug alcohol 9514293 On the contrary, no variables other than heavier alcohol consumption influenced the prevalence in ALDH2*1/*2. ALDH2 drug alcohol 9514293 Health promotion activities to prevent from alcohol dependence should focus on ALDH2*1/*1, especially those of middle age, and should include stress management as a part of their activities. ALDH2 addiction dependence 9514293 Health promotion activities to prevent from alcohol dependence should focus on ALDH2*1/*1, especially those of middle age, and should include stress management as a part of their activities. ALDH2 drug alcohol 9383169 We first investigated the relationship of the aldehyde dehydrogenase 2 (ALDH2) genotype to alcohol flushing for 53 normal volunteers. ALDH2 drug alcohol 9383169 The first examination of 53 normal volunteers showed that there were differences in the degree of alcohol flushing between the ALDH2 genotypes (P < 0.01). ALDH2 drug alcohol 9399694 This analysis has 80% power to detect a small to moderate effect of OPRM1 variation on alcohol dependence and 100% power to detect effects of the magnitude of the ALDH2*2 variant. ALDH2 addiction dependence 9399694 This analysis has 80% power to detect a small to moderate effect of OPRM1 variation on alcohol dependence and 100% power to detect effects of the magnitude of the ALDH2*2 variant. ALDH2 drug alcohol 9195888 The single genetic factor most strongly correlated with reduced alcohol consumption and incidence of alcoholism is a naturally occurring variant of mitochondrial aldehyde dehydrogenase (ALDH2). ALDH2 drug alcohol 9195888 ALDH2 deficient individuals exhibit an averse response to ethanol consumption, which is probably caused by elevated levels of blood acetaldehyde. ALDH2 drug alcohol 9195888 The structure of ALDH2 is important for the elucidation of its catalytic mechanism, to gain a clear understanding of the contribution of ALDH2 to the genetic component of alcoholism and for the development of specific ALDH2 inhibitors as potential drugs for use in the treatment of alcoholism. ALDH2 drug alcohol 9066994 In this report we determined the genotypes for three genes, ADH2, ADH3, and ALDH2 among subjects with alcohol dependence (n = 159) and ethnically matched normal controls (n = 149) for the four largest aboriginal groups (Atayal, Ami, Bunun, and Paiwan) in Taiwan. ALDH2 addiction dependence 9066994 In this report we determined the genotypes for three genes, ADH2, ADH3, and ALDH2 among subjects with alcohol dependence (n = 159) and ethnically matched normal controls (n = 149) for the four largest aboriginal groups (Atayal, Ami, Bunun, and Paiwan) in Taiwan. ALDH2 drug alcohol 9066994 On a group level, the rare frequencies of ALDH2*2, the inactive allele of ALDH2, among these aborigines may account partially for their vulnerability to alcohol use disorders. ALDH2 drug alcohol 9118876 A significant difference was observed only in alcohol drinking in subjects classified by aldehyde dehydrogenase 2 isozyme (ALDH2) genotype. ALDH2 drug alcohol 9118876 Habitual alcohol intake appeared to increase 8 OHdG in PMN from ALDH2 deficient subjects. ALDH2 drug alcohol 8837712 Moreover, these frequencies were not altered in alcoholics with inactive aldehyde dehydrogenase 2 (ALDH2), a well defined negative risk factor for alcoholism. ALDH2 drug alcohol 8773821 Alcohol metabolising genes and alcoholism among Taiwanese Han men: independent effect of ADH2, ADH3 and ALDH2. ALDH2 drug alcohol 8773821 The association of ALDH2 and ADH2 with the development of alcoholism was found to be independent of each other and has been replicated in different Asian populations, while the effect of ADH3 is less studied. ALDH2 drug alcohol 8773821 Multiple logistic regression was then applied to assess the contribution of ADH3 to alcoholism by controlling the effect of ALDH2 and ADH2. ALDH2 drug alcohol 8773821 The results of multivariate analyses demonstrated that the odds ratios for an increment of one allele of ADH2*1, ADH3*2 and ALDH2*1 in the development of alcoholism were 4.18, 3.82, and 6.89, respectively. ALDH2 drug alcohol 8929946 A point mutation in the aldehyde dehydrogenase 2 gene (ALDH2(2) allele) is considered to be a genetic deterrent for alcoholism; however, 80 of 655 Japanese alcoholics had the mutant allele. ALDH2 drug alcohol 8929946 Genotype factors that might increase susceptibility by overriding the deterrent showed a higher frequency of a five repeat allele of the dopamine D4 receptor 48 bp repeat polymorphism in alcoholics with ALDH2(2) than in 100 other alcoholics and 144 controls. ALDH2 drug alcohol 8651462 A comparison of the genotypes of ALDH2, ADH2, ADH3, and cytochrome P 4502E1 between alcoholics and nonalcoholics. ALDH2 drug alcohol 8651462 We also compared the frequencies of homozygous ALDH2*1/1 and heterozygous ALDH2*1/2 genotypes in alcoholics. ALDH2 drug alcohol 8651462 Our study revealed differences in the allelic frequencies of the ALDH2, ADH2, and ADH3 loci between alcoholics and nonalcoholics. ALDH2 drug alcohol 8651462 For alcoholics with both homozygous ALDH2*1/1 and heterozygous ALDH2*1/2 genotypes, it was found that ADH2 and ADH3 played important rates. ALDH2 drug alcohol 8651462 Alcoholics with the heterozygous ALDH2*1/2 genotype showed a significantly higher frequency of ADH2*1/1 than ones with the homozygous ALDH2*1/1 genotype. ALDH2 drug alcohol 8651462 We assume ADH2*1 plays an important role in the development of alcoholism in alcoholics with the heterozygous ALDH2*1/2 genotype. ALDH2 drug alcohol 8591846 High incidence of ADH2*1/ALDH2*1 genes among Japanese alcohol dependents and patients with alcoholic liver disease. ALDH2 drug alcohol 8591846 Genetic polymorphism of ADH2/ALDH2 in 66 cases of normal subjects, 90 cases of alcohol dependent, and 31 patients with alcoholic liver disease among Japanese has been analyzed using a polymerase chain reaction assay followed by a direct sequencing method, because ethanol is mainly catabolized by ADH and ALDH and less by cytochrome P450IIE1 and catalase. ALDH2 drug alcohol 8591846 The incidence of both ADH2*1/*1 and ALDH2*1/*1 was significantly higher in patients with alcohol dependence and in patients with alcoholic liver disease when compared with that in control subjects. ALDH2 addiction dependence 8591846 The incidence of both ADH2*1/*1 and ALDH2*1/*1 was significantly higher in patients with alcohol dependence and in patients with alcoholic liver disease when compared with that in control subjects. ALDH2 drug alcohol 8591846 In addition, the incidence of ALDH2*1/*2 and ALDH2*2/*2 was significantly reduced in alcoholics compared with control subjects. ALDH2 drug alcohol 8591846 Genetic polymorphism of ADH2/ALDH2 in patients with alcoholic liver disease was not different from that of alcohol dependents. ALDH2 drug alcohol 8591846 According to these results, not only ALDH2 gene, often claimed to be responsible for alcohol dependence among Japanese, but also ADH2 gene polymorphism, which modulates the metabolism of ethanol, play important roles in habitual alcohol intake behavior in Japanese patients and in some patients leads to alcoholic liver diseases. ALDH2 addiction dependence 8591846 According to these results, not only ALDH2 gene, often claimed to be responsible for alcohol dependence among Japanese, but also ADH2 gene polymorphism, which modulates the metabolism of ethanol, play important roles in habitual alcohol intake behavior in Japanese patients and in some patients leads to alcoholic liver diseases. ALDH2 drug alcohol 7573775 CYP2E1 and ALDH2 genotypes and alcohol dependence in Japanese. ALDH2 addiction dependence 7573775 CYP2E1 and ALDH2 genotypes and alcohol dependence in Japanese. ALDH2 drug alcohol 7573775 The genotypes of the CYP2E1 and ALDH2 loci of alcoholic (alcohol dependence) and nonalcoholic (healthy) Japanese were investigated to examine the relationship between the polymorphism of CYP2E1 (C1/C2) and ALDH2 (ALDH2*1/ALDH2*2), and the susceptibility to alcoholism. ALDH2 addiction dependence 7573775 The genotypes of the CYP2E1 and ALDH2 loci of alcoholic (alcohol dependence) and nonalcoholic (healthy) Japanese were investigated to examine the relationship between the polymorphism of CYP2E1 (C1/C2) and ALDH2 (ALDH2*1/ALDH2*2), and the susceptibility to alcoholism. ALDH2 drug alcohol 7573775 There was no significant difference in C2 gene frequency between alcoholics (0.19) and nonalcoholics (controls) (0.20), whereas there was a significant difference in ALDH2 allele frequency, suggesting that, in Japanese, the C2 genotype of CYP2E1 may have nothing to do with the risk of developing alcohol dependence. ALDH2 addiction dependence 7573775 There was no significant difference in C2 gene frequency between alcoholics (0.19) and nonalcoholics (controls) (0.20), whereas there was a significant difference in ALDH2 allele frequency, suggesting that, in Japanese, the C2 genotype of CYP2E1 may have nothing to do with the risk of developing alcohol dependence. ALDH2 drug alcohol 7573775 However, the ALDH2*1 allele may influence drinking behavior and the development of alcohol dependence.

ALDH2 drug alcohol 7718681 Heterozygous for ALDH2 in alcohol dependence: relationship between the ALDH2 genotype and personality disorder in alcohol dependent patients with the Flushing syndrome. ALDH2 addiction dependence 7718681 Heterozygous for ALDH2 in alcohol dependence: relationship between the ALDH2 genotype and personality disorder in alcohol dependent patients with the Flushing syndrome. ALDH2 drug alcohol 7755519 The present study investigates the influence of the ALDH2 allele and of acculturation in North America on alcohol consumption by Orientals born in Canada or the United States. ALDH2 drug alcohol 7755519 Oriental males carrying the inactive ALDH2( ) allele drink two thirds less alcohol (6.1 +/ 1.5 vs. 18.2 +/ 2.8 drinks/4 weeks; p < 0.001), show one third the prevalence of binge drinking (15.2 vs. 42.2%; p < 0.01), and are three times more likely to be abstainers (39.4 vs. 13.3%; p < 0.01) than Oriental ALDH2(+) males carrying the gene for the active enzyme. ALDH2 addiction intoxication 7755519 Oriental males carrying the inactive ALDH2( ) allele drink two thirds less alcohol (6.1 +/ 1.5 vs. 18.2 +/ 2.8 drinks/4 weeks; p < 0.001), show one third the prevalence of binge drinking (15.2 vs. 42.2%; p < 0.01), and are three times more likely to be abstainers (39.4 vs. 13.3%; p < 0.01) than Oriental ALDH2(+) males carrying the gene for the active enzyme. ALDH2 addiction intoxication 7755519 There were no significant differences in binge drinking or abstinence rates between ALDH2(+) Orientals and Caucasian males. ALDH2 drug alcohol 7755519 It is concluded that a single mutation in the high affinity aldehyde dehydrogenase (ALDH2) gene predicts two thirds of the alcohol consumption and excessive alcohol use by Oriental males born in North America. ALDH2 drug alcohol 7943668 Genetic variation at two polymorphic alcohol dehydrogenase loci, ADH2 and ADH3, and at the polymorphic mitochondrial aldehyde dehydrogenase locus, ALDH2, may influence the risk of developing alcoholism by modulating the rate of elimination of ethanol and the rate of formation and elimination of acetaldehyde. ALDH2 drug alcohol 7943668 The Atayal with alcohol use disorders also had a lower frequency of ALDH2*2 than the controls; this allele is known to be responsible for the alcohol flush reaction among Asians, and thereby deters drinking. ALDH2 drug alcohol 7513575 To study the alcohol consumption pattern and mitochondrial aldehyde dehydrogenase (ALDH2) genotype, a random sample consisting of 170 native males (Chukchee and the Eskimo), residents of 4 Chukotka settlements, was studied. ALDH2 drug alcohol 8290656 About half of Chinese individuals lack mitochondrial aldehyde dehydrogenase 2 (ALDH2) activity, which is responsible for the oxidation of acetaldehyde produced during ethanol metabolism. ALDH2 drug alcohol 8290656 The ALDH2 deficiency in Chinese has been implicated in alcohol flush reaction and reported to be a negative risk factor for development of alcohol dependence. ALDH2 addiction dependence 8290656 The ALDH2 deficiency in Chinese has been implicated in alcohol flush reaction and reported to be a negative risk factor for development of alcohol dependence. ALDH2 drug alcohol 8464153 All individuals with homozygous atypical ALDH2(2)/ALDH2(2) and most of those with heterozygous atypical ALDH2(1)/ALDH2(1) were alcohol flushers, while all of the usual ALDH2(1)/ALDH2(1) were nonflushers. ALDH2 drug alcohol 8464153 The results indicate that Japanese with the atypical ALDH2(2) allele are at a much lower risk in developing alcoholic liver disease than those with usual ALDH2(1)/ALDH2(1), presumably due to their sensitivity to alcohol intoxication. ALDH2 addiction intoxication 8464153 The results indicate that Japanese with the atypical ALDH2(2) allele are at a much lower risk in developing alcoholic liver disease than those with usual ALDH2(1)/ALDH2(1), presumably due to their sensitivity to alcohol intoxication. ALDH2 drug alcohol 1443441 Subjective feelings of alcohol intoxication in Asians with genetic variations of ALDH2 alleles. ALDH2 addiction intoxication 1443441 Subjective feelings of alcohol intoxication in Asians with genetic variations of ALDH2 alleles. ALDH2 drug alcohol 1443441 Asian American men who possess ALDH2*2 alleles and who experience a facial flush after consuming alcohol were carefully matched on drinking history and demographic variables with nonflushing Asian males with only ALDH2*1 alleles. ALDH2 drug alcohol 1443441 These data suggest that Asians who flush after drinking, particularly those with ALDH2*1/2*2 genotype, have a more intense, although not necessarily a more negative, response to alcohol than comparable nonflushing Asians. ALDH2 drug alcohol 3189338 Genetic polymorphisms of two major alcohol metabolizing enzymes i.e., one of the class I alcohol dehydrogenase isozymes (ADH2) and the mitochondrial aldehyde dehydrogenase (ALDH2) exist in Japanese and other Orientals but not in Caucasians. ALDH2 drug alcohol 3189338 We determined, by means of hybridization of genomic DNA samples with allele specific synthetic oligonucleotide probes, genotypes of the ADH2 and the ALDH2 loci of Japanese with alcoholic liver diseases and of control subjects. ALDH2 drug alcohol 3189338 The results indicate that Japanese with the atypical ALDH2(2) allele are at a much lower risk in developing the alcoholic liver diseases than are those with homozygous, usual (Caucasian type) ALDH1(2)/ALDH1(2), presumably owing to their sensitivity to alcohol intoxication. ALDH2 addiction intoxication 3189338 The results indicate that Japanese with the atypical ALDH2(2) allele are at a much lower risk in developing the alcoholic liver diseases than are those with homozygous, usual (Caucasian type) ALDH1(2)/ALDH1(2), presumably owing to their sensitivity to alcohol intoxication. ALDH2 drug alcohol 7180842 A remarkably higher frequency of acute alcohol intoxication among Orientals than among Caucasians could be related to the absence of the ALDH2 isozyme, which has a low apparent Km for acetaldehyde.

MAPK3 drug opioid 21088039 The inactivation of brain α(2) adrenoceptors (EEDQ at SW 12 h) further enhanced morphine abstinence intensity and cortical p FADD content at SW 24 h. The disruption of ERK1/2 signalling (SL 327 at SW 4 h and SW 8 h) did not alter morphine abstinence at SW 12 h, but it attenuated the behavioural syndrome at SW 24 h. This inhibition of ERK1/2, however, did not prevent the up regulation of oligomeric p FADD at SW 12 h and 24 h. These data indicate that cortical oligomeric p FADD, mainly through an interaction with inhibitory α(2) adrenoceptors, plays a functional role in the behavioural expression of morphine abstinence in rats.

NPS addiction reward 27147945 Neuropharmacology of New Psychoactive Substances (NPS): Focus on the Rewarding and Reinforcing Properties of Cannabimimetics and Amphetamine Like Stimulants. NPS drug alcohol 27147945 The use of NPS, mainly consumed along with other drugs of abuse and/or alcohol, has resulted in a significantly growing number of mortality and emergency admissions for overdoses, as reported by several poison centers from all over the world. NPS drug cannabinoid 27147945 The chemical structure (phenethylamines, piperazines, cathinones, tryptamines, synthetic cannabinoids) of NPS and their pharmacological and clinical effects (hallucinogenic, anesthetic, dissociative, depressant) help classify them into different categories. NPS drug cannabinoid 27147945 In the recent past, 50% of newly identified NPS have been classified as synthetic cannabinoids followed by new phenethylamines (17%) (UNODC, 2014b). NPS addiction addiction 27147945 Besides peripheral toxicological effects, many NPS seem to have addictive properties. NPS drug amphetamine 27147945 This manuscript will review existing literature about the addictive and rewarding properties of the most popular NPS classes: cannabimimetics (JWH, HU, CP series) and amphetamine like stimulants (amphetamine, methamphetamine, methcathinone, and MDMA analogs).

NPS drug alcohol 26897563 The catalytic activity of the synthesized Au Multipod NPs was evaluated in ethanol electrooxidation reaction. NPS addiction dependence 26810957 One of the most recent compounds to appear on the NPS market is the phenmetrazine analog 3 fluorophenmetrazine (3 FPM) which represents one of many phenylmorpholines designed to explore treatment options in areas such as obesity and drug dependence. NPS addiction addiction 26693960 Using European Monitoring Centre for Drugs and Drug Addiction Internet snapshot methodology, we undertook an English language Internet snapshot survey in May 2015 to gather information on the availability and price of phenibut from Internet NPS retailers. NPS addiction relapse 26680586 Additionally, the involvement of NPS in reinstatement of drug seeking behavior has also been reported. NPS drug amphetamine 26666629 The prevalence of all NPS (15.1 17.6%) was similar to amphetamine alone that was detected in 15.1 16.5% of cases. NPS drug cannabinoid 26666629 NPS (one or more) with other conventional drugs (like amphetamines, cannabinoids, cocaine, and benzodiazepines) were detected in most (65%) of the cases. NPS drug cocaine 26666629 NPS (one or more) with other conventional drugs (like amphetamines, cannabinoids, cocaine, and benzodiazepines) were detected in most (65%) of the cases. NPS drug benzodiazepine 26625894 The extinction facilitating potential of neuropeptide S, D cycloserine, and a benzodiazepine was investigated in extinction impaired high anxiety HAB rats and 129S1/SvImJ mice using a classical cued fear conditioning paradigm followed by extinction training and several extinction test sessions to study fear relapse. NPS addiction relapse 26625894 The extinction facilitating potential of neuropeptide S, D cycloserine, and a benzodiazepine was investigated in extinction impaired high anxiety HAB rats and 129S1/SvImJ mice using a classical cued fear conditioning paradigm followed by extinction training and several extinction test sessions to study fear relapse.

NPS addiction intoxication 26240749 Clinicians might encounter NPS in various ways: anecdotal reportage; acute intoxication; as part of a substance misuse profile; and as a precipitant or perpetuating factor for longer term physical and psychological ill health. NPS drug cannabinoid 26216566 NPS use was reported by 4.7% of the sample, without significant differences between urban and rural areas; mephedrone (3.3%), synthetic cannabinoids (1.2%) and Salvia divinorum (0.3%) consumption has been identified. NPS addiction intoxication 26216566 NPS use was also predictive of binge drinking behaviours (χ(2) (4) = 929.58, p < .001). NPS addiction intoxication 26216566 Moreover, the association between binge drinking habits and NPS use was really strong. NPS drug nicotine 26194894 NPS users were compared with non users and illicit drug users, who had not used NPS, in terms of gender, binge drinking, tobacco use, psychological distress and self efficacy to resist peer pressure. NPS addiction intoxication 26194894 NPS users were compared with non users and illicit drug users, who had not used NPS, in terms of gender, binge drinking, tobacco use, psychological distress and self efficacy to resist peer pressure. NPS drug cannabinoid 26194894 Of the 1126 students, 3% reported having ever tried NPS, 2.4% had used synthetic cannabis and 0.4% had used a synthetic stimulant. NPS drug nicotine 26194894 Analyses revealed that NPS users were more likely to have had an episode of binge drinking in the past 6 months, tried tobacco and had higher levels of psychological distress and lower perceived self efficacy to resist peer pressure than non users, but did not significantly differ from users of other illicit drugs.

NPS drug alcohol 26178067 Color controlled spherical Ag nanoparticles (NPs) and nanorods, with features that originate from their particle sizes and morphologies, can be synthesized within the mesoporous structure of SBA 15 by the rapid and uniform microwave (MW) assisted alcohol reduction method in the absence or presence of surface modifying organic ligands. NPS drug opioid 26083809 This report from the Swedish STRIDA project describes analytically confirmed non fatal intoxications involving butyrfentanyl (butyrylfentanyl) or 4 fluorobutyrfentanyl (para fluorobutyrfentanyl), two fentanyl analogues recently introduced as NPS opioids. NPS drug opioid 26083809 Analysis of two "butyrfentanyl" NPS products (nasal spray and powder) brought to hospital by patients showed that the 10 fold more potent fentanyl was the main active ingredient (∼7.5 10 fold higher amount) in both. NPS drug opioid 26083809 The incorrect labelling of butyrfentanyl NPS products which instead mainly contained fentanyl is alarming, given the narrow range between a safe and a lethal dose for opioids.

NPS addiction relapse 26055195 Intrahypothalamic injection of NPS facilitated discriminative cue induced reinstatement of alcohol seeking. NPS drug alcohol 26055195 Confirming this assumption, intra BNST or PVN Hcrt 1/Ox A injection enhanced alcohol seeking similarly to hypothalamic NPS injection but to a lesser degree. NPS addiction relapse 26055195 Confirming this assumption, intra BNST or PVN Hcrt 1/Ox A injection enhanced alcohol seeking similarly to hypothalamic NPS injection but to a lesser degree. NPS addiction relapse 26055195 Results suggest that the Hcrt 1/Ox A neurocircuitry mediating the facilitation of cue induced reinstatement by NPS involves structures critically involved in stress regulation such as the PVN and the BNST. NPS addiction relapse 26055195 These findings open to the tempting hypothesis of a role of the NPS system in modulating the interactions between stress and environmental conditioning factors in drug relapse.

NPS drug cocaine 25220242 These results support further consideration of NPS receptor antagonists as candidate treatments for cocaine abuse and provide evidence for differential effects of a candidate treatment on abuse related effects of cocaine and MDPV. NPS drug opioid 25175898 MT 45 (1 cyclohexyl 4 (1,2 diphenylethyl)piperazine) is an opioid analgesic drug candidate developed in the 1970s that has recently been introduced as a new psychoactive substance (NPS) on the "recreational" drug market. NPS drug alcohol 24754478 Neuropeptide S receptor gene variant and environment: contribution to alcohol use disorders and alcohol consumption. NPS drug alcohol 24754478 The functional polymorphism Asn(107) Ile (rs324981, A > T) of the neuropeptide S receptor (NPSR1) gene is involved in the modulation of traits that affect alcohol use. NPS addiction intoxication 24529166 A number of characteristics of the recreational use of NPS may not be well addressed by standard medical clinical trials, including binge use, polydrug use, use by vulnerable groups and high risk modes of administration. NPS drug alcohol 24529166 If the legal market for NPS encourages the use of NPS, alcohol and other drugs there may be an increase in drug related harm.

NPS drug alcohol 22739468 Chronic ethanol potentiates the effect of neuropeptide s in the basolateral amygdala and shows increased anxiolytic and anti depressive effects. NPS drug alcohol 22739468 We examined whether the neuropeptide S receptor (NPSR) was effective at controlling ethanol consumption and the anxiety and depression produced by forced abstinence from ethanol. NPS drug alcohol 22739468 We found that the anxiolytic and anti depressant effects of NPS are enhanced in acute ethanol abstinent mice. NPS drug alcohol 22739468 In addition, we found that NPS reduced ethanol consumption and is not in and of itself rewarding. NPS drug alcohol 22739468 We also provide evidence that ethanol consumption increases the ability of NPS to modulate neuronal activity in the basolateral amygdala. NPS drug alcohol 22739468 Finally, we found that local injection of NPS in the basolateral amygdala promotes anxiolysis after chronic ethanol consumption, thereby providing insight into the molecular mechanism underlying the changes in behavioral response to NPS. NPS drug alcohol 22739468 In light of the improved anxiolytic efficacy and benign side effects of NPS in ethanol withdrawn animals, the NPSR may prove a suitable target for reducing relapse in alcoholism.

CRHR1 drug cocaine 29180955 Here we examined the role of neuronal selectivity of CRHR1 within the mesolimbic system on cocaine induced behaviors. CRHR1 drug cocaine 29180955 We then studied cocaine sensitization, self administration, and reinstatement in inducible CRHR1 knockouts using the CreERT2/loxP in either dopamine transporter (DAT) containing neurons (DAT Crhr1) or dopamine receptor 1 (D1) containing neurons (D1 Crhr1).

CRHR1 drug alcohol 29118713 After having had continuous access to ethanol (20% weight/volume) for 4 weeks, control and stressed mice had CRF type 1 (CRFR1) or type 2 (CRFR2) receptor antagonists infused into the BNST and then had access to ethanol for 24 h. In separate cohorts of control and stressed mice, we assessed mRNA levels of BNST CRF, CRFR1 and CRFR2. CRHR1 drug alcohol 29118713 The selective blockade of BNST CRFR1 with CP376,395 effectively reduced alcohol drinking in non stressed mice, whereas the selective CRFR2 antagonist astressin2B produced a dose dependent increase in ethanol consumption in both non stressed controls and stressed mice. CRHR1 drug alcohol 29118713 CRF CRFR1 signaling in the BNST seems to underlie ethanol intake in non stressed mice, whereas CRFR2 modulates alcohol consumption in both socially defeated and non stressed mice with a history of chronic intake.

CRHR1 drug alcohol 28734867 Here we report that acute alcohol interacts with the CRF/CRF1 system, such that CRF and alcohol act via presynaptic CRF1s and P/Q type voltage gated calcium channels to promote vesicular GABA release and that both compounds occlude the effects of each other at these synapses. CRHR1 drug alcohol 28734867 Chronic alcohol exposure does not alter P/Q type voltage gated calcium channel membrane abundance or this CRF1/P/Q type voltage gated calcium channel mechanism of acute alcohol induced GABA release, indicating that alcohol engages this molecular mechanism at CeA GABAergic synapses throughout the transition to dependence.

CRHR1 drug cocaine 28698920 To further explore the role of CRFR1, CP 376,395 (0.5 and 1 μg/0.2 μl) was infused directly into the VTA before the cocaine self administration session. CRHR1 drug cocaine 28698920 Intra VTA antagonism of CRFR1 was sufficient to reverse social defeat stress escalated cocaine self administration. CRHR1 drug cocaine 28698920 These findings suggest that CRF and CRFR1 exert multiple roles in the response to social stress that are relevant to escalated cocaine self administration.

CRHR1 addiction sensitization 28431969 Moreover, the enhancement in locomotor sensitization was paralleled by a selective increase in the number of the c Fos+ cells, the level of CRFR1 mRNA in the ventromedial caudate putamen (vmCPu). CRHR1 drug cocaine 28431969 Furthermore, the enhancement was significantly attenuated by CRFR1 antagonist NBI 27914 into the vmCPu, implying that the up regulation of CRFR1 in the vmCPu seems to be critical in the acute stress enhanced expression of cocaine locomotor sensitization.

CRHR1 drug alcohol 27235163 We hypothesized that vmPFC CRF CRFR1 signaling contributes functionally to stress induced avoidance and escalated alcohol self administration. CRHR1 drug alcohol 27235163 In Experiment 3, rats were stressed and indexed, then tested for the effects of intra vmPFC CRFR1 antagonism on avoidance and alcohol self administration. CRHR1 drug alcohol 27235163 Intra vmPFC CRF infusion produced avoidance of a paired context, and intra vmPFC CRFR1 antagonism reversed avoidance of a stress paired context, but did not alter post stress alcohol self administration. CRHR1 drug alcohol 27798128 We previously demonstrated that CRF receptor 1 (CRF1) neurons comprise a specific component of the CeA microcircuitry that is selectively engaged by acute ethanol. CRHR1 drug alcohol 27798128 To investigate the impact of chronic ethanol exposure on inhibitory signaling in CRF1+ CeA neurons, we used CRF1:GFP mice subjected to chronic intermittent ethanol (CIE) inhalation and examined changes in local inhibitory control, the effects of acute ethanol, and the output of these neurons from the CeA. CRHR1 addiction withdrawal 27798128 Following CIE, CRF1+ neurons displayed decreased phasic inhibition and a complete loss of tonic inhibition that persisted into withdrawal. CRHR1 addiction withdrawal 27798128 CRF1 neurons showed a cell type specific upregulation of both phasic and tonic signaling with CIE, the latter of which persists into withdrawal and is likely mediated by δ subunit containing GABAA receptors. CRHR1 drug alcohol 27798128 CRF1+ projection neurons displayed an increased baseline firing rate and loss of sensitivity to acute ethanol following CIE. CRHR1 drug alcohol 27798128 These data demonstrate that chronic ethanol exposure produces profound and long lasting changes in local inhibitory control of the CeA, resulting in an increase in the output of the CeA and the CRF1 receptor system, in particular. CRHR1 drug alcohol 27798128 We showed previously that CRF receptor 1 expressing (CRF1+) neurons in the CeA are under tonic inhibitory control and are differentially regulated by acute ethanol (Herman et al., 2013). CRHR1 drug alcohol 27798128 Here we show that the inhibitory control of CRF1+ CeA neurons is lost with chronic ethanol exposure, likely by a functional switch in local tonic signaling. CRHR1 drug alcohol 27798128 The loss of tonic inhibition is seen in CRF1+ projection neurons, suggesting that a critical consequence of chronic ethanol exposure is an increase in the output of the CeA CRF1 system, a neuroadaptation that may contribute to the behavioral consequences of alcohol dependence.

CRHR1 drug alcohol 23398267 Several recent studies implementing the standard "drinking in the dark" (DID) model of short term binge like ethanol (EtOH) intake in C57BL/6J mice highlighted a role for the stress related neuropeptide corticotropin releasing factor (CRF) and its primary binding partner, the CRF type 1 (CRF1) receptor.

CRHR1 addiction intoxication 23398267 We evaluated the selectivity of CRF1 involvement in binge like EtOH intake by interrupting CRF1 function via pharmacological and genetic methods in a slightly modified 2 bottle choice DID model that allowed calculation of an EtOH preference ratio. CRHR1 addiction intoxication 23398267 Our findings indicate that blockade of CRF1 receptors does not exert specific effects on EtOH intake in the DID paradigm, and that slight modifications to this procedure, as well as additional consummatory control experiments, may be useful when evaluating the selectivity of pharmacological and genetic manipulations on binge like EtOH intake.

CRHR1 drug alcohol 22885872 Manipulation of the stress neuropeptide corticotropin releasing factor (CRF), specifically central antagonism of the type 1 receptors (CRF R1), effectively reduces alcoholic like ethanol drinking in rodents. CRHR1 drug alcohol 22885872 The current studies investigated the role of CRF R1 within the VTA and DRN and their relation to escalated ethanol drinking in two species. CRHR1 drug alcohol 22885872 An additional goal was to explore whether high alcohol drinking individuals would be more affected by CRF R1 antagonism than low alcohol drinking individuals. CRHR1 drug alcohol 22885872 Doses of the CRF R1 antagonist CP 154,526 (butyl [2,4,6 trimethylphenyl) 7H pyrrolo[2,3 d]pyrimidin 4 yl]ethylamine)) were microinfused to modulate drinking of ethanol and water over the course of 24 h. In both mice and rats, intra VTA CP 154,526 selectively decreased ethanol intake, while identical doses (0.3 and 0.6 μg) infused intra DRN reduced both ethanol and water drinking. CRHR1 drug alcohol 22885872 The current findings confirm previous studies that blockade of CRF R1 efficaciously reduces escalated drinking while also suggesting that the effects of intermittent access on alcohol consumption may require CRF interaction with dopamine in the VTA.

CRHR1 addiction relapse 21334600 In particular, behavioral studies point to a serial signaling process initiated by β adrenergic receptors that requires CRF receptor (CRFR) dependent signaling in the bed nucleus of the stria terminalis (BNST) to produce stress induced relapse to cocaine seeking. CRHR1 drug cocaine 21334600 We show that chronic cocaine administration transiently disrupts β(1) adrenergic and CRFR1 dependent enhancement of glutamatergic transmission, that this disruption wanes with time, and that it can be reintroduced with a cocaine challenge. CRHR1 drug alcohol 21258618 Previously, we found that both ethanol and corticotropin releasing factor (CRF) increase GABAergic transmission in mouse and rat CeA neurons, in part by enhancing the release of GABA via activation of presynaptic CRF1 receptors. CRHR1 addiction sensitization 20731720 The present studies addressed the involvement of specific components of the corticotropin releasing factor (CRF) system in locomotor activation and psychomotor sensitization induced by MA (1, 2 mg/kg) by utilizing pharmacological approaches, as well as a series of genetic knockout (KO) mice, each deficient for a single component of the CRF system: CRF R1, CRF R2, CRF, or the CRF related peptide Urocortin 1 (Ucn1). CRHR1 addiction sensitization 20731720 CRF R1 KO mice did not differ from wild type mice in sensitization to MA, and pharmacological blockade of CRF R1 with CP 154,526 (15, 30 mg/kg) in DBA/2J mice did not selectively attenuate either the acquisition or expression of MA induced sensitization. CRHR1 addiction sensitization 20731720 Deletion of either of the endogenous ligands of CRF R1 (CRF, Ucn1) either enhanced or had no effect on MA induced sensitization, providing further evidence against a role for CRF R1 signaling.

CRHR1 drug opioid 20052275 CRF1 R activation of the dynorphin/kappa opioid system in the mouse basolateral amygdala mediates anxiety like behavior. CRHR1 drug alcohol 19878140 An examination of alcohol consumption in adolescents reported a significant genotype x environment (G x E) interaction involving rs1876831, a corticotropin releasing hormone receptor 1 (CRHR1) polymorphism, and negative events.

CRHR1 addiction relapse 19800323 The reinstatement, glutamate release, and dopamine release are prevented by VTA infusions of CRF receptor 2 (CRF R2) but not CRF R1 antagonists. CRHR1 drug cocaine 19800323 Reinstatement is triggered by some but not all CRF R2 agonists and some but not all CRF R1 agonists; the common denominator of the effective agonists is that they bind to the CRF binding protein (CRF BP), which appears to be essential for the behavioral and VTA effects of stress and CRF in cocaine experienced animals.

CRHR1 drug alcohol 19785977 Variation in the CRF1 receptor gene has been shown to moderate stress induced alcohol drinking (gene environment interaction) in animals, and this finding was recently extended to humans. CRHR1 drug cocaine 19675537 Stress induced potentiation of cocaine reward: a role for CRF R1 and CREB. CRHR1 addiction reward 19675537 Stress induced potentiation of cocaine reward: a role for CRF R1 and CREB. CRHR1 drug opioid 19539724 We used electron microscopy to quantitatively compare immunolabeling of the corticotropin releasing factor receptor (CRFr) and CRF in the anterolateral bed nucleus of the stria terminalis (BSTal) of mice injected with saline or morphine in escalating doses for 14 days. CRHR1 drug opioid 19539724 The non injected controls had a significantly lower plasmalemmal density of CRFr immunogold particles in dendrites compared with mice receiving saline, but not those receiving morphine, injections. CRHR1 drug opioid 19539724 Compared with saline, however, mice receiving chronic morphine showed a significantly lower plasmalemmal, and greater cytoplasmic, density of CRFr immunogold in dendrites. CRHR1 drug opioid 19539724 Within the cytoplasmic compartment of somata and dendrites of the BSTal, the proportion of CRFr gold particles associated with mitochondria was three times as great in mice receiving morphine compared with saline. CRHR1 drug opioid 19539724 This subcellular distribution is consistent with morphine, and CRFr associated modulation of intracellular calcium release or oxidative stress. CRHR1 drug opioid 19539724 The between group changes occurred without effect on the total number of dendritic CRFr immunogold particles, suggesting that chronic morphine enhances internalization or decreases delivery of the CRFr to the plasma membrane, a trafficking effect that is also affected by the stress of daily injections. CRHR1 drug opioid 19539724 In contrast, saline and morphine treatment groups showed no significant differences in the total number of CRF immunoreactive axon terminals, or the frequency with which these terminals contacted CRFr containing dendrites. CRHR1 drug nicotine 19217073 Previous research has shown that blockade of corticotropin releasing factor (CRF) receptors with a nonspecific CRF1/CRF2 receptor antagonist prevents the deficit in brain reward function associated with nicotine withdrawal and stress induced reinstatement of extinguished nicotine seeking in rats.

CRHR1 drug cocaine 19181855 When injected in the acute binge paradigm, cocaine enhanced tPA activity in the amygdala, which required activation of corticotropin releasing factor type 1 (CRF R1) receptors. CRHR1 addiction intoxication 19181855 When injected in the acute binge paradigm, cocaine enhanced tPA activity in the amygdala, which required activation of corticotropin releasing factor type 1 (CRF R1) receptors. CRHR1 drug opioid 19166913 Thus, in both the CeA and BNST, mu OR and CRFr have strategic locations for mediation of CRF and opioid effects on the postsynaptic excitability of single neurons, and on the respective presynaptic release of excitatory and inhibitory neurotransmitters. CRHR1 drug alcohol 19151899 Presynaptic CRF1 receptors mediate the ethanol enhancement of GABAergic transmission in the mouse central amygdala. CRHR1 drug alcohol 19151899 We recently reported that the ethanol augmentation of GABAergic synaptic transmission in rat CeA involves CRF1 receptors, because both CRF and ethanol significantly enhanced the amplitude of evoked GABAergic inhibitory postsynaptic currents (IPSCs) in CeA neurons from wild type (WT) and CRF2 knockout (KO) mice, but not in neurons of CRF1 KO mice. CRHR1 drug alcohol 19151899 A CRF1 (but not CRF2) KO construct and the CRF1 selective nonpeptide antagonist NIH 3 (LWH 63) blocked the augmenting effect of both CRF and ethanol on evoked IPSCs. CRHR1 drug alcohol 19151899 The PPF effect of ethanol was abolished in CeA neurons of CRF1 KO mice. CRHR1 drug alcohol 19151899 The CRF1 antagonist NIH 3 blocked the CRF and ethanol induced enhancement of mIPSC frequency in CeA neurons. CRHR1 drug alcohol 19151899 These data indicate that presynaptic CRF1 receptors play a critical role in permitting or mediating ethanol enhancement of GABAergic synaptic transmission in CeA, via increased vesicular GABA release, and thus may be a rational target for the treatment of alcohol abuse and alcoholism. CRHR1 drug nicotine 19145226 The administration of the nonspecific CRF1/2 receptor antagonist D Phe CRF((12 41)) into the CeA and the Nacc shell prevented the mecamylamine induced elevations in brain reward thresholds in the nicotine dependent rats. CRHR1 addiction reward 19145226 The administration of the nonspecific CRF1/2 receptor antagonist D Phe CRF((12 41)) into the CeA and the Nacc shell prevented the mecamylamine induced elevations in brain reward thresholds in the nicotine dependent rats. CRHR1 drug nicotine 19145226 Blockade of CRF1/2 receptors in the lateral BNST did not prevent the mecamylamine induced elevations in brain reward thresholds in the nicotine dependent rats. CRHR1 addiction reward 19145226 Blockade of CRF1/2 receptors in the lateral BNST did not prevent the mecamylamine induced elevations in brain reward thresholds in the nicotine dependent rats. CRHR1 drug cocaine 19091975 Furthermore, we found that both in vivo and ex vivo cocaine induced a dopamine receptor and CRF R1 dependent enhancement of a form of NMDA receptor dependent short term potentiation in the BNST.

CRHR1 addiction dependence 18631323 Effects of CRF1 receptor and opioid receptor antagonists on dependence induced increases in alcohol drinking by alcohol preferring (P) rats. CRHR1 addiction sensitization 18591672 We posited that CRF1 signaling pathways are crucial for EtOH induced sensitization. CRHR1 addiction sensitization 18591672 We demonstrate that mice lacking CRF1 receptors do not show psychomotor sensitization to EtOH, a phenomenon that was also absent in CRF1 + 2 receptor double knockout mice. CRHR1 addiction sensitization 18591672 The CRF1 receptor antagonist CP 154,526 attenuated the acquisition and prevented the expression of EtOH induced psychomotor sensitization. CRHR1 addiction sensitization 18591672 Because CRF1 receptors are also activated by urocortin 1 (Ucn1), we tested Ucn1 knockout mice for EtOH sensitization and found normal sensitization in this genotype. CRHR1 addiction sensitization 18591672 CRF and CRF1 receptors, therefore, are involved in the neurobiological adaptations that underlie the development and expression of psychomotor sensitization to EtOH. CRHR1 addiction sensitization 18591672 A CRF/CRF1 mediated mechanism involving the HPA axis is proposed for acquisition, whereas an extrahypothalamic CRF/CRF1 participation is suggested for expression of sensitization to EtOH. CRHR1 addiction aversion 18184783 CRF induced place aversion was blocked by the CRF2 receptor antagonist antisauvigine 30, but not by the CRF1 receptor antagonist antalarmin.

CRHR1 drug alcohol 17919825 To determine the role of the CRF1 receptor in modulating the expression of ethanol induced sensitization, mice that had previously been sensitized to the locomotor stimulant effects of ethanol were pretreated with CP 154,526 30 min before an i.p.

CRHR1 drug alcohol 17919825 These data provide novel evidence that CRF1 receptor signaling modulates the expression of ethanol induced locomotor sensitization, and add to a growing literature suggesting a role for neurochemicals and hormones associated with the HPA axis in behavioral sensitization resulting from repeated exposure to drugs of abuse.

CRHR1 addiction dependence 17585886 Upregulation of voluntary alcohol intake, behavioral sensitivity to stress, and amygdala crhr1 expression following a history of dependence. CRHR1 drug alcohol 17585886 This persisted 3 months after alcohol exposure and was reversed by the selective CRH R1 antagonist 3 (4 Chloro 2 morpholin 4 yl thiazol 5 yl) 8 (1 ethylpropyl) 2,6 dimethyl imidazo[1,2 b]pyridazine (MTIP) (10 mg/kg).

CRHR1 addiction dependence 17407495 Corticotropin releasing hormone 1 receptors (CRH R1) mediate increased behavioral sensitivity to stress and excessive alcohol self administration following a history of dependence. CRHR1 drug alcohol 17407495 It was recently demonstrated that the genetically selected alcohol preferring msP rat line replicates many characteristics of the post dependent state, due to an innate up regulation of the Crhr1 transcript in several limbic areas related to alcohol drinking motivation. CRHR1 drug alcohol 17407495 Here, we examined whether voluntary alcohol consumption might be able to down regulate Crhr1 transcript levels in msP rats in brain areas where elevated expression previously has been shown. CRHR1 drug alcohol 17407495 Accumbens, 2 weeks'ad lib access to alcohol led to a highly significant down regulation of the Crhr1 transcript. CRHR1 drug alcohol 17407495 Alcohol induced Crhr1 down regulation was not seen in cingulate cortex. CRHR1 drug alcohol 17407495 These data support that recruitment of CRH R1 signaling within components of the extended amygdala drives excessive alcohol intake, and that alcohol is voluntarily consumed in part for its ability to reduce CRH R1 activity in this region. CRHR1 drug alcohol 17344409 We describe a novel corticotropin releasing factor receptor 1 (CRF1) antagonist with advantageous properties for clinical development, and its in vivo activity in preclinical alcoholism models.

CRHR1 addiction relapse 17015825 Variation at the rat Crhr1 locus and sensitivity to relapse into alcohol seeking induced by environmental stress. CRHR1 drug alcohol 17015825 An innate up regulation of the Crhr1 transcript, encoding the corticotropin releasing hormone receptor 1 (CRH R1), was found in several limbic brain areas of msP rats genetically selected for high alcohol preference, was associated with genetic polymorphism of the Crhr1 promoter, and was accompanied by increased CRH R1 density.

CRHR1 addiction relapse 17015825 These data demonstrate that Crhr1 genotype and expression interact with environmental stress to reinstate alcohol seeking behavior. CRHR1 addiction withdrawal 17004937 The enhanced CRF induced LTP after 2 weeks of withdrawal was mediated through augmented CRF1 receptor function, associated with an increased signalling through protein kinase A, and required N methyl D aspartate (NMDA) receptors. CRHR1 drug cocaine 17004937 These results support a role for CRF1 receptor antagonists as plausible treatment options during withdrawal from chronic cocaine and suggest Ca(V)2.3 blockers as potential candidates for pharmaceutical modulation of CRF systems.

CRHR1 addiction withdrawal 16339307 Here we report that genetic disruption of CRF1 receptor pathways in mice eliminates the negative affective states of opiate withdrawal. CRHR1 addiction withdrawal 16339307 In particular, neither CRF1 receptor heterozygous (CRF1+/ ) nor homozygous (CRF1 / ) null mutant mice avoided environmental cues repeatedly paired with the early phase of opiate withdrawal. CRHR1 drug opioid 16339307 These results were not due to altered associative learning processes because CRF1+/ and CRF1 / mice displayed reliable, conditioned place aversions to environmental cues paired with the kappa opioid receptor agonist U 50,488H.

CRHR1 drug benzodiazepine 15894069 Other groups of P and SD rats were injected with flumazenil (5 mg/kg), a benzodiazepine (BZD) receptor antagonist, CP 154,526 (10 mg/kg), CRF1 receptor antagonist, SB243,213, a 5 HT2C receptor inverse agonist, or vehicle during the 1st and 2nd withdrawals but not the third. CRHR1 drug alcohol 15894069 These findings show that alcohol preferring P rats exhibit anxiety like behavior more readily following exposure to ethanol containing diets and that this behavior is counteracted more readily by pretreatment with a CRF1 receptor antagonist than with BZD or 5 HT2C receptor antagonists. CRHR1 drug cocaine 15784652 Recently, CRF1 receptor antagonists have been shown to decrease cocaine self administration and inhibit stress induced reinstatement of cocaine seeking behavior. CRHR1 addiction relapse 15784652 Recently, CRF1 receptor antagonists have been shown to decrease cocaine self administration and inhibit stress induced reinstatement of cocaine seeking behavior. CRHR1 addiction reward 15784652 Based on the large amount of literature demonstrating an association between dopaminergic neurotransmission and reward related behavior, the aim of the present study was to examine the effects of acute versus chronic CRF1 receptor blockade on mesencephalic dopamine (DA) neuron activity (determined by in vivo extracellular recordings) and extracellular DA levels in the nucleus accumbens (Acb) (using in vivo microdialysis). CRHR1 drug cocaine 15784652 In addition, the effect of CRF1 receptor antagonism on cocaine induced DA overflow in the Acb was examined and correlated with DA neuron activity in the ventral tegmental area (VTA). CRHR1 drug cocaine 15784652 In addition, both acute and chronic CRF1 receptor antagonism significantly reduced cocaine stimulated DA overflow in the Acb, and this reduction was correlated with an attenuated cocaine induced inhibition of DA population activity. CRHR1 drug cocaine 15784652 Taken as a whole, these data demonstrate that, although DA neuron population activity exhibits tolerance to chronic CRF1 receptor antagonism (by CRA 0450), tolerance does not develop to the selective inhibition of cocaine induced DA release (in the Acb) and, as such, may be beneficial in the treatment of cocaine addiction.

CRHR1 drug cocaine 12576179 In addition to being associated with CRH input from the hypothalamus, the activation of the HPA axis by cocaine withdrawal may be, at least in part, due to the increased POMC and/or CRH R1 gene expression observed in the anterior pituitary after chronic 'binge' cocaine.

CRHR1 addiction intoxication 11045867 The levels of CRF, CRF1 receptor, and POMC mRNAs in the hypothalamic pituitary axis were measured after acute (1 day) or chronic (14 days) binge pattern alcohol administration. CRHR1 drug alcohol 11045867 CRF1 receptor mRNA levels in the anterior pituitary were decreased significantly after acute administration, with no change after chronic alcohol administration. CRHR1 drug alcohol 11045867 These results suggest that (1) rats exposed to chronic binge alcohol develop tolerance in HPA activity, as shown by no elevation of ACTH and an attenuated corticosterone response to chronic alcohol after initial dramatic elevations by acute alcohol administration; (2) a concurrent acute decrease in CRF1 receptor mRNA levels in the anterior pituitary is associated with increased HPA activity, and (3) alterations of POMC gene expression in the hypothalamic region may have implications for a molecular understanding of the neuroendocrine response to alcohol.

NFKB1 addiction addiction 28043969 The Role of NFkB in Drug Addiction: Beyond Inflammation. NFKB1 drug alcohol 28043969 It has recently been demonstrated that alcohol and other drugs of abuse can induce NFkB activity and cytokine expression in the brain. NFKB1 drug alcohol 28043969 A number of reviews have been published highlighting this effect of alcohol, and have linked increased NFkB function to neuroimmune stimulated toxicity. NFKB1 addiction addiction 28043969 However, in this review we focus on the potentially non immune functions of NFkB as possible links between NFkB and addiction. NFKB1 drug opioid 28043969 NFkB can induce the expression of a diverse set of gene targets besides inflammatory mediators, some of which are involved in addictive processes, such as opioid receptors and neuropeptides. NFKB1 addiction addiction 28043969 NFkB can induce the expression of a diverse set of gene targets besides inflammatory mediators, some of which are involved in addictive processes, such as opioid receptors and neuropeptides. NFKB1 addiction reward 28043969 NFkB mediates complex behaviors including learning and memory, stress responses, anhedonia and drug reward, processes that may lie outside the role of NFkB in the classic neuroimmune response. NFKB1 addiction addiction 28043969 Future studies should focus on these non immune functions of NFkB signaling and their association with addiction related processes.

NFKB1 drug alcohol 26857094 previous each alcohol gavage blocked the expression of high mobility group box 1 (HMGB1) danger signal and the innate immunity Toll like receptors 4 (TLR4) in frontal cortex, and inhibited the nuclear factor kappa B (NF kB) proinflammatory cascade induced by alcohol binge administration. NFKB1 addiction intoxication 26857094 previous each alcohol gavage blocked the expression of high mobility group box 1 (HMGB1) danger signal and the innate immunity Toll like receptors 4 (TLR4) in frontal cortex, and inhibited the nuclear factor kappa B (NF kB) proinflammatory cascade induced by alcohol binge administration. NFKB1 drug alcohol 21927955 A testable scheme for this pathway is presented that incorporates recent findings in the alcohol brain literature indicating a role for neuroimmune activation (upregulation of NF kappaB, proinflammatory cytokines, and toll like receptors). NFKB1 addiction addiction 20477932 Nuclear factor kappa B (NFkappaB) is a sensor of oxidative stress and participates in memory formation that could be involved in drug toxicity and addiction mechanisms. NFKB1 drug cocaine 20477932 Therefore NFkappaB activity, oxidative stress, neuronal nitric oxide synthase (nNOS) activity, spatial learning and memory as well as the effect of topiramate, a previously proposed therapy for cocaine addiction, were evaluated in an experimental model of cocaine administration in rats. NFKB1 addiction addiction 20477932 Therefore NFkappaB activity, oxidative stress, neuronal nitric oxide synthase (nNOS) activity, spatial learning and memory as well as the effect of topiramate, a previously proposed therapy for cocaine addiction, were evaluated in an experimental model of cocaine administration in rats. NFKB1 drug cocaine 20477932 NFkappaB activity was decreased in the frontal cortex of cocaine treated rats, as well as GSH concentration and glutathione peroxidase activity in the hippocampus, whereas nNOS activity in the hippocampus was increased. NFKB1 drug cocaine 20477932 Memory retrieval of experiences acquired prior to cocaine administration was impaired and negatively correlated with NFkappaB activity in the frontal cortex. NFKB1 drug cocaine 20477932 These results provide evidence for a possible mechanistic role of oxidative and nitrosative stress and NFkappaB in the alterations induced by cocaine. NFKB1 drug alcohol 20388501 Pathway analysis showed that alcohol differentially affected various pathways in a K ras dependent manner some of which previously shown to be regulated by alcohol including the insulin/PI3K pathway, the NF kappaB, the phosphodiesterases (PDEs) pathway, the Jak/Stat and the adipokine signaling pathways. NFKB1 drug alcohol 20201932 Ethanol exposure increases NF kappaB DNA binding in rat brain (Crews et al., 2006) and in brain slice cultures in vitro (Zou and Crews, 2006).

NFKB1 drug alcohol 19561104 In contrast, chronic alcohol decreased IRAK M expression but increased IRAK 1 and IKK kinase activities, NFkappaB DNA binding, and NFkappaB reporter activity. NFKB1 drug alcohol 19561104 In summary, inhibition of LPS induced NFkappaB and ERK activation by acute alcohol leads to hyporesponsiveness of monocytes to LPS due to increased IRAK M. In contrast, chronic alcohol sensitizes monocytes to LPS through decreased IRAK M expression and activation of NFkappaB and ERK kinases.

NFKB1 drug cocaine 19295158 Therefore, we evaluated the role of NFkappaB in regulating cocaine induced dendritic spine changes on medium spiny neurons of the NAc and the rewarding effects of cocaine. NFKB1 drug cocaine 19295158 We show that chronic cocaine induces NFkappaB dependent transcription in the NAc of NFkappaB Lac transgenic mice. NFKB1 drug cocaine 19295158 This induction of NFkappaB activity is accompanied by increased expression of several NFkappaB genes, the promoters of which show chromatin modifications after chronic cocaine exposure consistent with their transcriptional activation. NFKB1 drug cocaine 19295158 We found that activation of NFkappaB by IKKca increases the number of dendritic spines on NAc neurons, whereas inhibition of NFkappaB by IKKdn decreases basal dendritic spine number and blocks the increase in dendritic spines after chronic cocaine. NFKB1 drug cocaine 19295158 Moreover, inhibition of NFkappaB blocks the rewarding effects of cocaine and the ability of previous cocaine exposure to increase an animal's preference for cocaine. NFKB1 drug cocaine 19295158 Together, these studies establish a direct role for NFkappaB pathways in the NAc to regulate structural and behavioral plasticity to cocaine.

NFKB1 drug opioid 18040804 Nuclear factor kappaB (NF kappaB), one of the most diverse and critical transcription factors, is one of the downstream molecules that may either directly or indirectly transmit the receptor mediated upstream signals to the nucleus, resulting in the regulation of the NF kappaB dependent genes, which are critical for the opioid induced biological responses of neuronal and immune cells. NFKB1 drug opioid 18040804 In this minireview, we focus on current understanding of the involvement of NF kappaB signaling in opioid functions and receptor gene expression in cells. NFKB1 drug alcohol 17895971 Neuroadaptations in human chronic alcoholics: dysregulation of the NF kappaB system. NFKB1 drug alcohol 17895971 Here we investigated whether transcription factors of Nuclear Factor kappaB (NF kappaB) family, controlling neuronal plasticity and neurodegeneration, are involved in these adaptations in human chronic alcoholics. NFKB1 drug alcohol 17895971 Analysis of DNA binding of NF kappaB (p65/p50 heterodimer) and the p50 homodimer as well as NF kappaB proteins and mRNAs was performed in postmortem human brain samples from 15 chronic alcoholics and 15 control subjects. NFKB1 drug alcohol 17895971 NF kappaB and p50 homodimer DNA binding was downregulated, levels of p65 (RELA) mRNA were attenuated, and the stoichiometry of p65/p50 proteins and respective mRNAs was altered in the prefrontal cortex of alcoholics. NFKB1 drug alcohol 17895971 Comparison of a number of p50 homodimer/NF kappaB target DNA sites, kappaB elements in 479 genes, down or upregulated in alcoholics demonstrated that genes with kappaB elements were generally upregulated in alcoholics. NFKB1 drug alcohol 17895971 We suggest that cycles of alcohol intoxication/withdrawal, which may initially activate NF kappaB, when repeated over years downregulate RELA expression and NF kappaB and p50 homodimer DNA binding.

NFKB1 drug alcohol 17127267 Recent findings indicate that low concentrations of ethanol (10 mM) promote inflammatory processes in brain and in glial cells by up regulating cytokines and inflammatory mediators (iNOS, NO, COX 2), and by activating signaling pathways (IKK, MAPKs) and transcriptional factors (NF kappaB, AP 1) implicated in inflammatory injury.

NFKB1 drug alcohol 16385231 Moreover, it was shown that Kupffer cell activation by endotoxin via Toll like receptor (TLR) 4 is involved in alcohol induced liver injury and ethanol induced oxidative stress is important in the regulation of transcription factor NFkappaB activation and cytokine production by Kupffer cells. NFKB1 drug alcohol 16385231 In Kupffer cells from mice 1 hr after ethanol treatment, expression of IRAK was decreased, and LPS induced activation of NFkappaB was decreased correlatively. NFKB1 drug alcohol 16385231 In contrast, ethanol treatment to mice increased expression of IRAK in Kupffer cells 21hrs later and LPS induced activation of NFkappaB was elevated significantly. NFKB1 drug alcohol 16385231 Further, NADPH oxidase plays a pivotal role in the increase in IRAK expression due to ethanol via activation of NFkappaB signaling pathway. NFKB1 drug alcohol 16317704 Alcohol administration to ob/ob mice did not increase oxidative stress despite increased CYP2E1, but increased plasma TNF alpha, further increased Hsp70, and profoundly decreased p65 nuclear factor kappaB (NF kappaB) protein and DNA binding activity in nuclear extracts. NFKB1 drug alcohol 16317704 Moderate ethanol intoxication does not increase oxidative stress in obese mice, but increases TNF alpha and also decreases nuclear NF kappaB activity, thus unleashing the apoptotic effects of TNF alpha.

NFKB1 drug opioid 15048644 We found correspondence between linkage and microarray/candidate gene studies for genes involved with the mitogen activated protein kinase (MAPK) signaling system, nuclear factor kappa B (NFKB) complex, neuropeptide Y (NPY) neurotransmission, a nicotinic receptor subunit (CHRNA2), the vesicular monoamine transporter (SLC18A2), genes in pathways implicated in human anxiety (HTR7, TDO2, and the endozepine related protein precursor, DKFZP434A2417), and the micro 1 opioid receptor (OPRM1). NFKB1 drug alcohol 14576487 The injurious effects of ethanol on the pancreas may be mediated through (1) sensitization of acinar cells to CCK induced premature activation of zymogens; (2) potentiation of the effect of CCK on the activation of transcription factors, nuclear factor kappaB (NF kappaB) and activating protein 1 (AP 1); (3) generation of toxic metabolites such as acetaldehyde and fatty acid ethyl esters; (4) sensitization of the pancreas to the toxic effects of coxsackievirus B3; and (5) activation of pancreatic stellate cells by acetaldehyde and oxidative stress and subsequent increased production of collagen and other matrix proteins. NFKB1 addiction sensitization 14576487 The injurious effects of ethanol on the pancreas may be mediated through (1) sensitization of acinar cells to CCK induced premature activation of zymogens; (2) potentiation of the effect of CCK on the activation of transcription factors, nuclear factor kappaB (NF kappaB) and activating protein 1 (AP 1); (3) generation of toxic metabolites such as acetaldehyde and fatty acid ethyl esters; (4) sensitization of the pancreas to the toxic effects of coxsackievirus B3; and (5) activation of pancreatic stellate cells by acetaldehyde and oxidative stress and subsequent increased production of collagen and other matrix proteins. NFKB1 drug alcohol 12958018 Ethanol differentially regulates NF kappaB activation in pancreatic acinar cells through calcium and protein kinase C pathways. NFKB1 drug alcohol 12958018 Previously, we showed that ethanol feeding sensitizes rats to pancreatitis caused by CCK 8, at least in part, by augmenting activation of the proinflammatory transcription factor NF kappaB. NFKB1 drug alcohol 12958018 To elucidate the mechanism of sensitization, here we investigate the effect of ethanol on Ca(2+) and PKC mediated pathways of CCK induced NF kappaB activation using an in vitro system of rat pancreatic acini incubated with ethanol. NFKB1 addiction sensitization 12958018 To elucidate the mechanism of sensitization, here we investigate the effect of ethanol on Ca(2+) and PKC mediated pathways of CCK induced NF kappaB activation using an in vitro system of rat pancreatic acini incubated with ethanol. NFKB1 drug alcohol 12958018 Ethanol augmented CCK 8 induced activation of NF kappaB, similar to our in vivo findings with ethanol fed rats. NFKB1 drug alcohol 12958018 In contrast, ethanol prevented NF kappaB activation caused by thapsigargin, an agent that mobilizes intracellular Ca(2+) bypassing the receptor. NFKB1 drug alcohol 12958018 Pharmacological analysis showed that NF kappaB activation by thapsigargin but not by CCK 8 is mediated through the calcineurin pathway and that the inhibitory effect of ethanol on the thapsigargin induced NF kappaB activation could be through inhibiting this pathway. NFKB1 drug alcohol 12958018 Ethanol augmented NF kappaB activation induced by the phorbol ester PMA, a direct activator of PKC. NFKB1 drug alcohol 12958018 Inhibitory analysis demonstrated that Ca(2+) independent (novel and/or atypical) PKC isoforms are involved in NF kappaB activation induced by both CCK 8 and PMA in cells treated and not treated with ethanol. NFKB1 drug alcohol 12958018 The results indicate that ethanol differentially affects the Ca(2+)/calcineurin and PKC mediated pathways of NF kappaB activation in pancreatic acinar cells. NFKB1 drug cocaine 12706249 However, expression of Deltac Jun in adult mice blocked the ability of chronic cocaine administration to induce three known targets for AP 1 in the NAc: the AMPA glutamate receptor subunit GluR2, the cyclin dependent protein kinase Cdk5, and the transcription factor nuclear factor kappaB (NFkappaB), without affecting several other proteins examined for comparison. NFKB1 drug amphetamine 12504868 In addition, DNA binding activities of NF kappaB, AP 1, and CREB in the frontal cortex and hippocampus were more pronounced in mice injected with Tat plus METH compared to the effects of Tat or METH alone. NFKB1 drug alcohol 12482856 Additionally, overexpression of SOD also blunted ethanol induced activation of redox sensitive transcription factors NFkappaB and AP 1 and production of cytokines. NFKB1 drug alcohol 12482856 However, only inhibition of AP 1 with dominant negative TAK1 but not NFkappaB by dominant negative IkappaBalpha significantly blunted ethanol induced increases in CD14, suggesting that AP 1 is important for CD14 transcriptional regulation.

NFKB1 drug alcohol 12045006 Chronic ethanol feeding significantly enhanced MNP 1 binding, but not those of NF kappaB and AP 1 in endothelial cells. NFKB1 drug alcohol 11994208 Ethanol and LPS modulate NF kappaB activation, inducible NO synthase and COX 2 gene expression in rat liver cells in vivo. NFKB1 drug alcohol 11994208 Ethanol and LPS are immunomodulators, whose actions are associated with the activation of the transcription factor, NF kappaB, that mediates the expression of a number of rapid response genes involved in the whole body inflammatory response to injury, including transcriptional regulation of iNOS and COX 2. NFKB1 drug alcohol 11994208 We investigated modulation by acute ethanol (EtOH) intoxication, LPS and LPS tolerance of NF kappaB activation in hepatocytes, Kupffer cells and sinusoidal endothelial cells (SEC), concurrent regulation of iNOS and COX 2 gene expression and the influence of gender on these mechanisms.

NFKB1 addiction withdrawal 11474844 The results of the present study indicate that NF kB is involved in the expression of opiate withdrawal thus extending and explaining previous papers performed with dexamethasone and selective arachidonic acid metabolites inhibitors. NFKB1 drug alcohol 11062014 In Kupffer cells from mice treated with ethanol 1 h earlier, LPS induced TNFalpha production, and IRAK expression and activity and NFkappaB were decreased 50 60% of control. NFKB1 drug alcohol 11062014 In contrast, in Kupffer cells from mice treated with ethanol 21 h earlier, LPS induced TNFalpha production, expression and activity of IRAK were increased 1.5 fold over controls, while NFkappaB was elevated 3 fold.

COMT addiction relapse 17467918 In this regard, based on the current literature we hypothesize that manipulation of catechol O methyl transferase (COMT) activity to influence the attenuation of substance seeking behavior, is dependent upon gene polymorphisms. COMT drug alcohol 17467918 In this regard we hypothesize that carrying the LL genotype with low COMT activity should as theorized, increase the reward induced by substance induced dopamine release and may indeed increase the propensity to type 1 alcoholism and possibly other drugs that activate the dopaminergic system.

COMT drug alcohol 17467918 Thus when alcohol is present in low COMT LL genotype, increasing COMT activity, not inhibiting it should assist in the reduction of social consumption or abuse. COMT drug alcohol 17467918 Thus, in the absence of alcohol or other psychoactive drugs (dopamine releasers), especially during recovery or rehabilitation, decreasing, not increasing COMT activity, should result in enhanced synaptic dopamine as physiologically released, thereby proliferating D2 receptors while reducing stress, increasing well being, reducing craving behavior and preventing relapse.

CRH drug alcohol 22384198 Therefore, we tested the hypothesis that 17β estradiol (E(2)), the predominant sex steroid hormone in females, prevents alcohol induced changes in CRH and AVP gene expression in the paraventricular nucleus (PVN) of the hypothalamus. CRH drug alcohol 22384198 Further, repeated binge pattern alcohol exposure significantly decreased CRH and AVP mRNA in Ch , but not E(2) treated animals, which was consistent with our previous observations in gonad intact females. CRH addiction intoxication 22384198 Further, repeated binge pattern alcohol exposure significantly decreased CRH and AVP mRNA in Ch , but not E(2) treated animals, which was consistent with our previous observations in gonad intact females. CRH drug alcohol 22384198 We further tested the effects of E(2) and alcohol treatment on the activity of the wild type CRH promoter in a PVN derived neuronal cell line. CRH drug alcohol 22384198 Alcohol increased CRH promoter activity in these cells and concomitant treatment with E(2) completely abolished the effect. CRH drug alcohol 22384198 Together our data suggest that E(2) regulates the reactivity of the HPA axis to a repeated stressor through modulation of the habituation response and further serves to maintain normal steady state mRNA levels of CRH and AVP in the PVN in response to a repeated alcohol stressor. CRH drug alcohol 22341871 In oil and estradiol injected ethanol treated females, CRH mRNA levels did not change in response to LPS stimulation, whereas those of vasopressin increased, but stayed below control levels.

CRH drug alcohol 22113086 Especially, post dependent and stress induced alcohol intake involve CRH/CRHR1 signaling within extra hypothalamic structures, but a contribution of the hypothalamic pituitary adrenal (HPA) axis activity might be involved as well. CRH drug alcohol 22113086 To dissect CRH/CRHR1 extra HPA and HPA signaling on a molecular level, a conditional brain specific Crhr1 knockout (Crhr1(NestinCre)) and a global knockout mouse line were studied for basal alcohol drinking, stress induced alcohol consumption, deprivation induced intake, and escalated alcohol consumption in the post dependent state. CRH drug alcohol 22113086 We conclude that CRH/CRHR1 extra HPA and HPA signaling may have opposing effects on stress related alcohol consumption.

CRH drug alcohol 22036774 The aim of the present study was to evaluate whether the CRH system is also recruited when non dependent Wistar rats escalate to high alcohol intake in the intermittent (alternate days) model of drinking. CRH drug alcohol 22036774 Pharmacological blockade of CRH1R reduced alcohol drinking when sustained high levels of intake were achieved suggesting that the CRH system plays a key role when high doses of ethanol are consumed by non dependent subjects. CRH addiction dependence 22036774 This supports the notion that CRH system not only maintains the dependent state but also engages the transition to dependence. CRH addiction dependence 21998007 Adverse childhood experiences (ACEs) increase the risk for adult depression and substance dependence, possibly mediated by the corticotropin releasing hormone type 1 receptor (CRHR1). CRH drug alcohol 21934176 Studies using corticotropin releasing hormone stimulation and tests after ethanol ingestion revealed inconclusive results. CRH addiction relapse 21843515 The role of CRF2 receptors in stress induced relapse to drug seeking also opens the question of the putative role of the other peptides of the CRH family (urocotin 1, urocortin 2 and urocortin 3) that have high affinity for CRF2 receptors. CRH drug alcohol 21835193 Ethanol induced stimulation in preweanling rats required the activation of CRH 1 receptors.

CRH drug benzodiazepine 14659475 Specifically, we demonstrate that (1) psychogenic stressors influence the in vivo release of CRH at the central nucleus of the amygdala (CeA); (2) although CRH changes within the CeA are exquisitely sensitive to stressors, they are also elicited by positive stimuli; and (3) while treatment with diazepam attenuates behavioral signs of anxiety, the CRH release associated with a stressor is unaffected by the treatment.

CRH drug alcohol 8367033 Similar to beta EP, an immediate sharp increase of corticotropin releasing hormone (CRH) release was induced by ethanol which, however, did not present a spike but was maintained significantly higher than spontaneous release for the duration of ethanol exposure. CRH drug alcohol 8367033 Both ethanol induced beta EP and CRH release returned to basal levels within 10 min following removal of ethanol. CRH drug alcohol 8367033 That beta EP levels did not remain elevated for the duration of ethanol exposure was not due to tissue depletion of releasable beta EP pool, since exposure of the hypothalami to 10( 8) M CRH for 10 min, immediately after the perifusion with 20 mM ethanol, resulted in a large increase of beta EP release.

PDYN drug opioid 32487735 Since then, ~20 peptides with opioid receptor activity have been discovered, all of which are generated from three precursors (proenkephalin, prodynorphin, and proopiomelanocortin) by sequential proteolytic processing by prohormone convertases and carboxypeptidase E. Each of these peptides bind to all three of the opioid receptor types (mu, delta, kappa), albeit with differing affinities. PDYN drug opioid 32393639 It is generally thought that the three types of opioid receptors (μ, δ, κ) are activated by endogenous peptides derived from three different precursors: Proopiomelanocortin, proenkephalin, and prodynorphin. PDYN drug alcohol 32099099 Conditional gene knockout resulted in sex specific responses wherein PDYN knockout decreased alcohol drinking in both male and female mice, whereas KOR knockout decreased drinking in males only. PDYN drug alcohol 32099099 We also found that neither PDYN nor KOR knockout protected against anxiety caused by alcohol drinking. PDYN drug alcohol 32099099 Lastly, a history of alcohol drinking did not alter synaptic transmission in PDYN neurons in the CeA of either sex, but excitability of PDYN neurons was increased in male mice only. PDYN drug alcohol 32099099 Taken together, our findings indicate that PDYN and KOR signaling in the CeA plays an important role in regulating excessive alcohol consumption and highlight the need for future studies to examine how this is mediated through downstream effector regions.

PDYN drug opioid 29925858 Prodynorphin (PDYN) gives rise to dynorphin (DYNs) opioid peptides which target kappa opioid receptor (KOR). PDYN drug alcohol 29925858 We addressed this hypothesis by comparing the expression levels and co expression (transcriptionally coordinated) patterns of PDYN and KOR (OPRK1) genes in dorsolateral prefrontal cortex (dlPFC) between human alcoholics and controls. PDYN drug alcohol 29925858 PDYN was found to be downregulated in dlPFC of alcoholics, while OPRK1 transcription was not altered. PDYN drug alcohol 29925858 PDYN downregulation was confined to subgroup of subjects carrying C, a high risk allele of PDYN promoter SNP rs1997794 associated with alcoholism. PDYN drug alcohol 29925858 Changes in PDYN expression did not depend on the decline in neuronal proportion in alcoholics, and thereby may be attributed to transcriptional adaptations in alcoholic brain. PDYN drug alcohol 29925858 Absolute expression levels of PDYN were lower compared to those of OPRK1, suggesting that PDYN expression is a limiting factor in the DYN/KOR signaling, and that the PDYN downregulation diminishes efficacy of DYN/KOR signaling in dlPFC of human alcoholics.

PDYN drug opioid 16861108 In this study, we determined the prodynorphin gene expression and dynorphin levels in selected brain regions of opioid tolerant rats. PDYN drug opioid 16861108 We found that in the striatum morphine decreased, while oxycodone 6 oxime increased and 14 methoxymetopon did not alter the prodynorphin gene expression. PDYN drug opioid 16861108 In the nucleus accumbens, morphine and oxycodone 6 oxime did not change, while 14 methoxymetopon increased the prodynorphin gene expression. PDYN drug opioid 16861108 In the hippocampus both oxycodone 6 oxime and 14 methoxymetopon enhanced, whereas morphine did not alter the prodynorphin gene expression. PDYN drug opioid 16861108 In the rat striatum only oxycodone 6 oxime increased dynorphin levels significantly in accordance with the prodynorphin mRNA changes. PDYN drug opioid 16861108 In the hippocampus both opioid agonists increased the dynorphin levels significantly similarly to the augmented prodynorphin gene expression. PDYN drug opioid 16861108 Since the endogenous prodynorphin system may play a modulatory role in the development of opioid tolerance, the elevated supraspinal dynorphin levels appear to be partly responsible for the reduced degree of tolerance induced by the investigated opioids.

PDYN drug cocaine 16412997 In the present study, effects of response dependent (contingent) and response independent (noncontingent) cocaine administration on the PENK and PDYN gene expression in the rat forebrain have been directly compared using the "yoked" self administration procedure. PDYN drug cocaine 16412997 In situ hybridization analysis revealed that levels of the PDYN mRNA were significantly increased in the caudate/putamen, to the same extent in rats self administering cocaine as in animals receiving noncontingent injections of the drug at the same frequency and dosage. PDYN drug cocaine 16412997 The obtained data indicate that up regulation of the PDYN gene expression in the caudate/putamen results from direct pharmacological actions of cocaine rather than from the motivational and cognitive processes underlying active self administration of the drug.

PDYN addiction dependence 16314761 A functional prodynorphin promoter polymorphism and opioid dependence. PDYN drug opioid 16314761 These data suggest that the PDYN repeat polymorphism should be studied in additional opioid dependent populations. PDYN drug opioid 16289352 We studied the effects of single and repeated 3,4 methylenedioxy N methylamphetamine ('Ecstasy') on the gene expression of the opioid precursor prodynorphin, and on the levels of peptide dynorphin A in the rat brain. PDYN drug psychedelics 16289352 We studied the effects of single and repeated 3,4 methylenedioxy N methylamphetamine ('Ecstasy') on the gene expression of the opioid precursor prodynorphin, and on the levels of peptide dynorphin A in the rat brain.

PDYN addiction dependence 16184603 Confirmation of the association between a polymorphism in the promoter region of the prodynorphin gene and cocaine dependence. PDYN drug cocaine 16184603 It has recently been reported that the variable nucleotide tandem repeat (VNTR) polymorphism in the 5' promoter region of the prodynorphin gene, which encodes the precursor for three endogenous opioid peptides, is associated with the cocaine dependent phenotype. PDYN drug opioid 16184603 It has recently been reported that the variable nucleotide tandem repeat (VNTR) polymorphism in the 5' promoter region of the prodynorphin gene, which encodes the precursor for three endogenous opioid peptides, is associated with the cocaine dependent phenotype. PDYN drug cocaine 16184603 In order to confirm this finding, we genotyped the prodynorphin promoter polymorphism in cocaine dependent (n = 167) and control (n = 88) individuals of African descent. PDYN drug cocaine 16184603 The results from this experiment indicate a statistically significant (chi2 = 5.64, OR = 1.59, P = 0.018) association between the prodynorphin promoter VNTR polymorphism and the cocaine dependent phenotype. PDYN drug cocaine 16184603 In contrast to previous work showing increased risk conferred by one or two copies of the prodynorphin VNTR, the genotyping results from this study indicate that persons with three or four copies of this polymorphism are more likely to become cocaine dependent. PDYN drug cocaine 16184603 This disparity suggests that the prodynorphin promoter VNTR may not be the functional polymorphism associating with the cocaine dependent phenotype.

PDYN addiction withdrawal 15869750 ISH analyses confirmed previous findings; EtOH withdrawal increased Pdyn mRNA in multiple brain regions of WSP mice, but not WSR. PDYN drug cocaine 15869520 The results also demonstrate that cocaine administration increases the expression of MC4 R in the nucleus accumbens and striatum, and that MC4 R is co localized with prodynorphin in medium spiny neurons in the nucleus accumbens. PDYN drug cocaine 15857718 Second, we examined the effects of repeated cocaine administration on locomotor activity, dopamine overflow and striatal prodynorphin mRNA expression. PDYN drug cocaine 15857718 Postmortem analyses of striatal prodynorphin mRNA expression (using in situ hybridization histochemistry) revealed a differentiated response to the cocaine exposure. PDYN drug cocaine 15857718 In contrast to control FRL rats, the FSL rats showed no typical cocaine evoked elevation of prodynorphin mRNA levels in rostral subregions of the striatum whereas both strains expressed increased prodynorphin mRNA levels in the caudal striatum after cocaine administration.

HTR1B drug cocaine 17291490 In order to substantiate the concept that cocaine behavioral effects may be influenced by serotonin (5 HT)1B receptors, male Wistar rats were trained to self administer cocaine intravenously (0.5 mg/kg/injection), and were systemically pretreated with the selective 5 HT1B receptor antagonist N [3 [3 (dimethylamine)ethoxy] 4 methoxyphenyl] 2' methyl 4' (5 methyl 1,2,4 oxadiazol 3 yl) [1,1' biphenyl] 4 carboxamide hydrochloride (SB 216641), or with the agonist 5 propoxy 3(1,2,3,6 tetrahydro 4 pyridinyl) 1H pyrrolo[3,2 b]pyridine hydrochloride (CP 94253) before test session during the maintenance phase.

HTR1B drug alcohol 16212943 The results also showed that intra tegmental infusion of CP 94253, a 5 HT1B receptor agonist, significantly prolonged the effects of ethanol on NACC DA. HTR1B drug alcohol 16212943 The results suggest that blockade and activation of VTA 5 HT1B receptors attenuates and potentiates the neurochemical effects of ethanol, respectively, and support the suggestion that VTA 5 HT(1B) receptors may be involved in part in mediating the activating effects of ethanol on mesolimbic DA neurons. HTR1B drug cocaine 15885246 Cocaine facilitates dopamine transmission from ventral tegmental area (VTA) neurons that project to nucleus accumbens (NAcc), and previous experiments suggest that serotonin 1B (5 HT1B) receptors are involved in this effect.

HTR1B drug cocaine 12486179 Elevated expression of 5 HT1B receptors in nucleus accumbens efferents sensitizes animals to cocaine. HTR1B drug cocaine 12486179 For example, serotonin actions at 5 HT1B receptors in the ventral tegmental area (VTA) modulate cocaine induced dopamine release in the nucleus accumbens (NAcc) and alter the rewarding and stimulant properties of cocaine. HTR1B drug cocaine 12486179 HA1B GFP injection induced elevated expression of 5 HT1B receptors in neuronal fibers in VTA and increased cocaine induced locomotor hyperactivity without affecting baseline locomotion. HTR1B drug cocaine 12486179 Overexpression of 5 HT1B receptors also shifted the dose response curve for cocaine conditioned place preference to the left, indicating alterations in the rewarding effects of cocaine. HTR1B drug cocaine 12486179 Thus, increased expression of 5 HT1B receptors in NAcc efferents, probably in the terminals of medium spiny neurons projecting to the VTA, may contribute to psychomotor sensitization and offer an important target for regulating the addictive effects of cocaine.

HTR1B drug cocaine 11396515 On the other hand, they also show that pharmacological activation of 5 HT1B receptors enhances both phases of this phenomenon, and that repeated administration of cocaine leads to an increased functional reactivity of these receptors. HTR1B drug cocaine 11374326 The mice lacking the 5 HT1B receptor have also been reported to exhibit an increased vulnerability to cocaine. HTR1B drug alcohol 11198050 Results showed that the 5 HT releaser d fenfluramine, the selective serotonin reuptake inhibitor fluoxetine, the 5 HT1A receptor agonist 8 hydroxy 2[di n propylamino]tetralin, the partial 5 HT1A receptor agonist buspirone, and the 5 HT1B/5 HT2C receptor agonist 1 (3 trifluoromethylphenyl)piperazine, but not the 5 HT2A/5 HT2C receptor agonist 1 (2,5 dimethoxy 4 iodophenylaminopropane) 2, selectively reduced responding on a lever leading to presentation of an ethanol paired conditioned stimulus.

HTR1B drug cocaine 11164086 Modulation of the effects of cocaine by 5 HT1B receptors: a comparison of knockouts and antagonists. HTR1B drug cocaine 11164086 To evaluate the role of the 5 HT1B receptor in mediating the actions of cocaine, we used two model systems: knockout (KO) mice lacking the 5 HT1B receptor and an acute treatment with the 5 HT1B/1D antagonist GR127935. HTR1B drug cocaine 11164086 In contrast, as demonstrated previously, the 5 HT1B receptor KO mice showed a heightened locomotor response to cocaine, as well as an increased propensity to self administer cocaine. HTR1B drug cocaine 11164086 Thus, an acute pharmacological blockade of the 5 HT1B receptor decreases some effects of cocaine, while a constitutive genetic KO of the same receptor has opposite effects. HTR1B drug cocaine 11164086 These results suggest that compensatory changes have taken place during the development of the 5 HT1B KO mice, which may have rendered these mice more vulnerable to cocaine. HTR1B drug cocaine 10837864 This study investigated the involvement of the serotonin 1B (5 HT1B) receptor in modulating cocaine induced place conditioning by comparing the response of 5 HT1B receptor gene knock out mice with wild type 129/Sv ter mice. HTR1B drug cocaine 10837864 Results clearly show that 5 HT1B receptor knock out mice failed to display a conditioned place preference for stimuli paired with cocaine while wild type mice exhibited a conditioned place preference for the compartment paired with cocaine (5 and 20 mg/kg). HTR1B drug cocaine 10837864 As other studies showed that 5 HT1B knock out mice self administer cocaine, these results suggest a dissociation between the psychologic state linked to self administration and the one measured in conditioned place preference.

HTR1B drug alcohol 10403028 Since KO mice showed greater levels of ethanol responding only for unsweetened 10% v/v ethanol, and showed modest ethanol self administration overall, the present results are not consistent with the notion that 5 HT1b KO have a generally greater preference for ethanol than 5 HT1b WT mice.

HTR1B drug alcohol 10334495 These findings suggest that operant ethanol self administration can be suppressed in a specific manner by activation of 5 HT2A and, possibly, 5 HT2C receptors, and in a nonselective manner by activation of 5 HT1B receptors.

HTR1B addiction reward 9744857 These results demonstrate that, under the present experimental conditions, activation of central 5 HT1A, 5 HT1B, and 5 HT2 receptors reduced ethanol intake and reinforced behaviour in an operant paradigm. HTR1B drug alcohol 9694030 These studies thus confirm the potential for decreasing ethanol consumption and ethanol preference of 5 HT1A agonists and 5 HT3 antagonists, but failed to find any selective effects for agents acting at 5 HT1B or 5 HT2 receptors. HTR1B addiction reward 9616795 We explore the concept of impulsivity and its relation with the neurotransmitter serotonin in the context of aggressive behavior and behavior associated with positive reinforcement using a knockout mouse that lacks one of the serotonin receptors, the 5 HT1B receptor. HTR1B drug cocaine 9603521 Here we examine the effects of cocaine in mice lacking one of the serotonin receptor subtypes, the 5 HT1B receptor. HTR1B drug cocaine 9603521 We show that mice lacking 5 HT1B display increased locomotor responses to cocaine and that they are more motivated to self administer cocaine. HTR1B drug cocaine 9603521 We propose that even drug naive 5 HT1B knockout mice are in a behavioural and biochemical state that resembles that of wild type mice sensitized to cocaine by repeated exposure to the drug.

HTR1B drug cocaine 9218264 The present experiment tested the hypothesis that 5 HT1B receptors are involved in the reinforcing effects of cocaine. HTR1B addiction reward 9218264 The present experiment tested the hypothesis that 5 HT1B receptors are involved in the reinforcing effects of cocaine. HTR1B drug cocaine 9218264 Transgenic mice lacking 5 HT1B receptors were used as subjects and compared with wild type mice for the acquisition and maintenance of intravenous (IV) cocaine self administration. HTR1B drug cocaine 9218264 Male 129/Sv ter and 5 HT1B minus 129/Sv ter inbred mice (Columbia University, New York) were initially trained to press a lever under a fixed ratio schedule 2, first for sweetened condensed milk as reinforcer and subsequently for cocaine (2.0 mg/kg/infusion). HTR1B drug cocaine 9218264 These results suggest that the 5 HT1B receptors may be implicated in the propensity to self administer cocaine, but other mechanisms might be involved in the maintenance of cocaine self administration. HTR1B addiction reward 9200507 The 5 HT1 agonist 5 carboxamidotryptamine (19 and 38 nanomol) and the 5 HT1B agonist, CGS 12066B (1.12 and 2.24 nanomol), but not the non selective 5 HT agonist m CPP (41 to 164 nanomol), 5 HT2 agonist alpha methylserotonin (36 and 72 nanomol) and 5 HT3 agonist 2 methylserotonin (36 and 72 nanomol), produced a dose dependent antinociceptive effect. HTR1B drug opioid 9200507 These results indicate that the antinociceptive effects of opioid or serotonergic agonists microinjected into the APtN depend on drug interaction with local mu or 5 HT1B receptors, respectively. HTR1B addiction reward 8956376 The effect of 5 HT1B receptor stimulation on dopamine mediated reinforcement in rats was investigated using intravenous self administration of the selective dopamine uptake inhibitor GBR 12909 on an FR5 schedule of reinforcement. HTR1B drug cocaine 8956376 Finally, CGS 12066B pretreatment (1 10 mg/kg, IP) did not alter the self administration of cocaine (0.03 0.5 mg/injection), suggesting that the simultaneous stimulation of multiple 5 HT receptor subtypes by the indirect 5 HT agonist properties of cocaine may mask the effect of 5 HT1B receptor stimulation on DA mediated reinforcement.

HTR1B drug alcohol 8842634 Alterations in serotonin1B (5HT1B) receptor subtypes in the brain of ethanol treated rats. HTR1B drug alcohol 8842634 The effects of acute or chronic ethanol treatment and of withdrawal (24 h) after chronic ethanol treatment on 5HT1B receptor subtypes in different regions of the rat brain were investigated. HTR1B addiction withdrawal 8842634 The effects of acute or chronic ethanol treatment and of withdrawal (24 h) after chronic ethanol treatment on 5HT1B receptor subtypes in different regions of the rat brain were investigated. HTR1B drug alcohol 8842634 It was observed that acute ethanol treatment had no significant effect on the maximum number of binding sites (Bmax) or the apparent dissociation constant (KD) of 5HT1B receptor binding sites in the various brain regions. HTR1B drug alcohol 8842634 On the other hand, chronic ethanol treatment produced a significant increase in Bmax of 125I CYP binding to 5HT1B receptors in the rat cortex and hippocampus, which remained increased after 24 h of ethanol withdrawal. HTR1B addiction withdrawal 8842634 On the other hand, chronic ethanol treatment produced a significant increase in Bmax of 125I CYP binding to 5HT1B receptors in the rat cortex and hippocampus, which remained increased after 24 h of ethanol withdrawal. HTR1B drug alcohol 8842634 In contrast, in the striatum and the cerebellum of chronic ethanol treated and withdrawn rats, the 5HT1B binding parameters (Bmax and KD) were unchanged. HTR1B drug alcohol 8842634 These results suggest the possible involvement of cortical and hippocampal 5HT1B receptors in ethanol dependence. HTR1B addiction dependence 8842634 These results suggest the possible involvement of cortical and hippocampal 5HT1B receptors in ethanol dependence. HTR1B addiction withdrawal 8521905 The expression of central 5 HT1A and 5 HT1B receptors was studied in several brain areas of rats subjected to a 2 week period of chronic alcoholization, followed by 18 h withdrawal. HTR1B drug alcohol 8521905 These data suggest that altered sensitivity of chronically alcoholized rats to 5 HT1A and 5 HT1B receptor ligands may result from alcohol induced changes in the transcription of the genes encoding these receptors. HTR1B drug opioid 7733277 The stimulatory effect of morphine, dexmedetomidine (an alpha 2 adrenoceptor agonist), 1 (3 chlorophenyl) piperazine (m CPP, a 5 HT1B agonist), U 50488H (a kappa opioid receptor agonist), pimozide (a dopamine antagonist), and restraint stress on prolactin and growth hormone (GH) secretion was compared during cold exposure (4 degrees C) and under basal conditions (30 degrees C) in male rats.

HTR1B addiction addiction 7898613 The long lasting effect of ibogaine on serotonergic functioning, in particular, its blocking of the 5HT1B agonist mediated increase in dopamine efflux, may have significance in the mediation of its anti addictive properties. HTR1B drug cocaine 8332619 Overall, the results indicate that, at least in the present behavioral paradigm, the effects of chronic cocaine administration are mediated by changes in 5 HT1A receptor sensitivity but not by changes in 5 HT1B receptor sensitivity. HTR1B drug alcohol 7748340 This is indicated by (a) lower contents of DA and 5 HT; (b) fewer 5 HT immunostained fibers; (c) lower densities of 5 HT1B, 5 HT2 and D2 receptors; and (d) higher densities of 5 HT1A receptors in the CNS of P rats compared to the alcohol nonpreferring NP line of rats. HTR1B addiction reward 1532259 Metachlorophenylpiperazine (mCPP) 2.5 mg/kg IP, an agonist at 5 HT1B and 5 HT1C receptors, and d fenfluramine (DF) 1.25 mg/kg IP, a releaser of 5 HT from nerve terminals and inhibitor of 5 HT uptake, increased the percentage of omissions and the latency to respond correctly or to collect the reinforcement with no effects on the correct responses. HTR1B drug alcohol 1839497 [3H]Ketanserin binding to 5 HT2 receptors in the cortex, ( )[125I] iodo cyanopindolol [(125I]CYP) binding to 5 HT1b receptors in the striatum and hypothalamus, and [3H] 8 OH DPAT binding in the cortex were not affected by chronic ethanol administration. HTR1B addiction reward 1975107 5 HT agonists selective for other receptor subtypes, such as the 5 HT1B/1C agonist m CPP (5 mg/kg) and the 5 HT2/1C agonist DOB (1 mg/kg), were not effective in this behavioral test. HTR1B addiction reward 2746512 It is likely that the hypoactivity and PRL responses of m CPP are mediated by 5 HT1B receptors, and the cardiodepressive effects by 5 HT1A receptors. HTR1B drug opioid 2566495 8 Hydroxy 2 (di n propylamino)tetralin (8 OH DPAT) and RU 24969 have been used to investigate whether 5 HT1A and 5 HT1B receptors are involved in the naloxone induced jumping behaviour of the chronically morphine dependent mouse. HTR1B drug alcohol 2648491 In addition, administration of a 5 HT1B agonist also attenuated the oral intake of ethanol by P rats. HTR1B drug alcohol 3228486 The cross generalization between ethanol and THBC is, thus, indicated and relates to previous evidence in which both ethanol and THBC trained rats generalize to a common agent, TFMPP, a putatively specific 5HT1B receptor agonist.

FOSB drug cocaine 32742260 Finally, we found that (1) CPEB is reduced in transgenic mice following cocaine injections and that (2) FosB, known for its contribution to establishing the addictive phenotype, when its expression in the striatum is increased by drug administration, is a novel target of CPEBs molecules.

FOSB drug cocaine 32457073 We identified 133 genes differentially expressed between CUD case patients and cocaine free control subjects, including previously implicated candidates for cocaine use/addiction (FOSB, ARC, KCNJ9/GIRK3, NR4A2, JUNB, and MECP2). FOSB addiction addiction 32457073 We identified 133 genes differentially expressed between CUD case patients and cocaine free control subjects, including previously implicated candidates for cocaine use/addiction (FOSB, ARC, KCNJ9/GIRK3, NR4A2, JUNB, and MECP2). FOSB drug amphetamine 31952958 Furthermore, sensitized behavioral responding to and for amphetamine following exposure to uncertainty is accompanied by increased levels of Ca2+/calmodulin dependent protein kinase II (CaMKII) and protein kinase C (PKC) phosphorylation as well as altered protein levels of the transcription factor ∆FosB (increased) and glutamate transporter 1 (GLT1; decreased) in NAcc tissues. FOSB addiction relapse 31952958 Increased ∆FosB and decreased GLT1 levels are observed following psychostimulant exposure, are associated with increased drug taking and seeking, and are known to modulate AMPA receptors and extracellular glutamate levels respectively. FOSB drug cocaine 31477569 Epigenetic Regulation of Hippocampal Fosb Expression Controls Behavioral Responses to Cocaine. FOSB drug cocaine 31477569 Further, we characterize changes in histone modifications at the FosB promoter in hippocampus in response to chronic cocaine and found that locus specific epigenetic modification is essential for FosB induction and multiple hippocampus dependent behaviors, including cocaine place preference. FOSB drug cocaine 31477569 Collectively, these findings suggest that exposure to cocaine induces histone modification at the hippocampal FosB gene promoter to cause ΔFosB induction critical for cocaine related learning.SIGNIFICANCE STATEMENT Although cocaine addiction is driven in part by the formation of indelible associations between the drug and the environment, paraphernalia, and circumstances of use, and although this type of associative learning is dependent upon changes in gene expression in a brain region called the hippocampus, the mechanisms by which cocaine alters hippocampal gene expression to drive formation of these associations is poorly understood.

FOSB drug cocaine 31477569 Here, we demonstrate that chronic cocaine engages locus specific changes in the epigenetic profile of the FosB gene in the hippocampus, and that these alterations are required for cocaine dependent gene expression and cocaine environment associations. FOSB drug opioid 31442272 H3K4 dimethylation at FosB promoter in the striatum of chronic stressed rats promotes morphine induced conditioned place preference. FOSB addiction addiction 31442272 Expression of FosB gene in striatum is essential in addiction establishment. FOSB addiction addiction 31442272 Therefore, elevation of FosB expression in striatum serves as one mechanism by which stress increases risk for addiction. FOSB addiction addiction 31442272 In this study, adult male Sprague Dawley rats were used to investigate whether chronic stress result in histone modifications at FosB gene promoter in striatum and how these histone modifications affect FosB expression and the establishment of addiction behavior after administration of drugs of abuse. FOSB drug opioid 31442272 Before and after morphine administration, FosB mRNA in striatum was quantified by real time RT PCR. FOSB drug opioid 31442272 Levels of histone H3/H4 acetylation and histone H3K4 dimethylation at FosB promoter in striatum after morphine administration were measured by using chromatin immunoprecipitation (ChIP) plus real time PCR. FOSB drug opioid 31442272 EFS group had stronger place preference to morphine and had significantly higher level of FosB mRNA in striatum than the other two groups. FOSB drug opioid 31442272 Mifepristone administration before EFS decreased histone H3K4 dimethylation and FosB mRNA in striatum, and also diminished morphine induced conditioned place preference. FOSB drug opioid 31442272 Altogether, increased level of H3K4 dimethylation at FosB promoter in striatum is partially dependent on the activation of GR and responsible for the elevated level of morphine induced FosB mRNA in chronic stressed animals. FOSB drug psychedelics 31373119 Regional changes in ∆FosB expression in rat brain following MDMA self administration predict increased sensitivity to effects of locally infused MDMA. FOSB drug psychedelics 31373119 The effects of extensive 3,4 methylenedioxymethamphetamine (MDMA) self administration on immunohistochemical measurements of ∆FosB accumulation in 12 brain regions was compared with a matched, drug naive, control group. FOSB drug psychedelics 31373119 Other groups were pretreated with MDMA (0.0 or 10.0 mg/kg, ip, once daily for 5 days), and the locomotor activating effect of MDMA (200 μg/side) microinjected bilaterally into brain regions selected on the basis of the ∆FosB results was subsequently determined. FOSB drug psychedelics 31373119 MDMA self administration significantly increased ∆FosB expression in the nucleus accumbens core, ventromedial and dorsomedial caudate putamen, anterior cingulate, prelimbic, infralimbic, and orbitofrontal cortex, and both the central and basolateral amygdala, but not in the ventrolateral or dorsolateral caudate putamen. FOSB drug psychedelics 31373119 MDMA pretreatment enhanced MDMA produced hyperactivity only when administered into the nucleus accumbens or the medial, but not the lateral, caudate putamen, mirroring the ∆FosB results. FOSB drug cocaine 31043484 RNA sequencing revealed five genes upregulated in cocaine relative to food self administering mice: Fosb, Npas4, Vgf, Nptx2, and Pmepa1, which reflect known and novel cocaine plasticity associated genes. FOSB drug amphetamine 30967896 FOS and FOSB, which are implicated in the amphetamine addiction pathway, were up regulated in schizophrenia fibroblast samples. FOSB addiction addiction 30967896 FOS and FOSB, which are implicated in the amphetamine addiction pathway, were up regulated in schizophrenia fibroblast samples. FOSB drug cocaine 30963104 Fosb Induction in Nucleus Accumbens by Cocaine Is Regulated by E2F3a. FOSB drug cocaine 30963104 We further conclude that ΔFosB expression is regulated specifically by E2F3a, not E2F3b, that E2f3a expression is specific to D1 receptor expressing medium spiny neurons, and that E2F3a overexpression in NAc recapitulates the induction of Fosb and ΔFosb mRNA expression observed after chronic cocaine exposure. FOSB drug cocaine 30803445 This behavioral alteration in spinophilin knockout mice was accompanied by attenuated c Fos and ∆FosB expression following cocaine administration and blunted cocaine induced phosphorylation of ERK1/2 in the striatum, with no change in other relevant signaling molecules. FOSB drug cocaine 30803445 Therefore, we suggest spinophilin fulfills an essential role in cocaine induced behavioral sensitization, likely via ERK1/2 phosphorylation and induction of c Fos and ∆FosB in the striatum, a mechanism that may underlie specific processes in cocaine addiction.

FOSB drug opioid 30632799 Tramadol induces changes in Δ FosB, µ opioid receptor, and p CREB level in the nucleus accumbens and prefrontal cortex of male Wistar rat. FOSB drug opioid 30632088 Interestingly, morphine induced elevations of FosB/ΔFosB+ cells were suppressed by TMCA (50, 100 mg/kg) in the nucleus accumbens sub shell region of mice. FOSB addiction relapse 30405417 The genic expression of FosB seems to be modified after long time exposure to drugs of abuse and these changes may be involved in craving and addicted behavior. FOSB drug cocaine 30030395 Using primary striatal cultures, we show that transcription of Dnmt3a2, but not that of Dnmt3a1, is activated by dopamine D1 receptor signaling and that knockdown of Dnmt3a2 using viral vector mediated expression of Dnmt3a2 specific shRNAs impairs induction of the IEGs, Arc, FosB, and Egr2 Acute cocaine administration increases expression of Dnmt3a2 but not that of Dnmt3a1 in the NAc shell. FOSB drug cocaine 30030395 shRNA mediated knockdown of Dnmt3a2 in vivo impairs the induction of IEGs, including Egr2 and FosB indicating that Dnmt3a2 regulates cocaine dependent expression of plasticity genes in the rat NAc shell. FOSB drug cocaine 29740282 Immediate early gene (IEG) expression (cFos and FosB) induced by repeated cocaine injections was significantly increased in the forebrain of M4R D1RCre mice, whereas it remained normal in the M4R ChATCre mice. FOSB drug alcohol 29306704 At transcriptional level, ethanol reduced the upregulation of a subset of IEGs encoding for transcription factors such as Atf3, c Fos, FosB, Egr1, Egr3 and Npas4 but did not affect the upregulation of others (e.g. FOSB addiction reward 29093669 Gene expression analysis after CPP test revealed specific up regulation in the CAF COC group of Drd1a, cFos, and FosB in the NAc, and cFos, Egr1, and Npas4 in the mPFC. FOSB drug cocaine 28963688 However, the functional consequences of regulated expression patterns of Fosb and Crem (cAMP response element modulator) in both brain regions in response to volitional intake of cocaine in social environment is yet to be explored. FOSB drug cocaine 28963688 These changes were accompanied by hypomethylation or hypermethylation in the promoters of Fosb and Crem genes in the PFC and HPC of the cocaine experienced mice, respectively. FOSB drug cocaine 28963688 Furthermore, our data delineate the molecular response of Crem and Fosb to oral cocaine in group housed mice and demonstrates differential regulation of activities within the substrate brain regions studied. FOSB drug cocaine 28710498 In particular, we identified an AP 1 regulated transcriptional network in dlPFC neurons associated with cocaine use disorder that contains several differentially expressed hub genes. FOSB drug cocaine 27957784 Following CPP, we tested if DCS were able to reduce FosB/∆FosB protein expression, a molecular switch for cocaine seeking behaviour. FOSB addiction relapse 27957784 Following CPP, we tested if DCS were able to reduce FosB/∆FosB protein expression, a molecular switch for cocaine seeking behaviour. FOSB addiction reward 27957784 Following CPP, we tested if DCS were able to reduce FosB/∆FosB protein expression, a molecular switch for cocaine seeking behaviour. FOSB drug cocaine 27815415 We used mice expressing the eGFP protein in D1 receptor positive (D1R(+)) neurons to determine whether Δ FosB induced by enriched environment or cocaine injections (5×15 mg/kg) would occur in selective subpopulations of neurons in several subregions of the striatum and prefrontal cortex. FOSB drug cocaine 27815415 We found that: (1) exposure to enriched environment reduces cocaine induced locomotor activation, confirming our previous findings; (2) exposure to enriched environment by itself increases the accumulation of Δ FosB mostly in D1R( ) cells in the shell part of the nucleus accumbens and dorsal striatum, whereas in the nucleus accumbens core, Δ FosB accumulates in both D1R(+) and D1R( ) neurons; (3) in standard environment mice, cocaine induces accumulation of Δ FosB selectively in D1R(+) cells in the nucleus accumbens, dorsal striatum, and infralimbic cortex; and (4) the effects of enriched environments and cocaine on accumulation of Δ FosB were reciprocally blocked by their combination. FOSB drug cocaine 27664298 ERK (extracellular regulated kinase), CREB (cAMP responsive element binding protein), FosB and ΔFosB proteins were of particular interest due to their involvement in cocaine reward and in synaptic plasticity underlying learning and memory.

FOSB drug cocaine 27664298 We also show that cocaine induced increases in Caudate Putamen (CPu) FosB and ΔFosB levels are decreased after MK 801 pre treatment during conditioning. FOSB addiction addiction 27494187 Differential Expression of FosB Proteins and Potential Target Genes in Select Brain Regions of Addiction and Depression Patients. FOSB drug cocaine 27494187 Here, we use biochemistry to examine the expression of the FosB family of transcription factors and their potential gene targets in PFC and HPC postmortem samples from depressed patients and cocaine addicts. FOSB drug cocaine 27494187 Thus, we provide the first evidence of FosB gene expression in human HPC and PFC in these psychiatric disorders, and in light of recent findings demonstrating the critical role of HPC ΔFosB in rodent models of learning and memory, these data suggest that reduced ΔFosB in HPC could potentially underlie cognitive deficits accompanying chronic cocaine abuse or depression.

FOSB drug amphetamine 27339870 Further results of western blot experiments showed that repeated administration of METH caused the increases in the levels of Ras, pERK/ERK and ∆FosB in the CPu, and these changes were inhibited by only the 2.5 mg/kg dose of ifenprodil. FOSB drug amphetamine 27339870 Moreover, GluN2B containing NMDARs and their downstream Ras ERK ∆FosB signaling pathway in the CPu might be involved in METH induced behavioral sensitization.

FOSB addiction withdrawal 26655477 However, the relationship between NMDAR and FosB/ΔFosB in sensitive brain regions during morphine withdrawal is largely unknown. FOSB drug opioid 26655477 In this study, we aimed to investigate NMDAR dynamics and FosB/ΔFosB levels in multiple brain regions and whether they are related in sensitive brain regions during morphine abstinence. FOSB drug opioid 26655477 Quantitative immunohistochemistry was adopted to test NMDAR and FosB/ΔfosB levels during morphine withdrawal in rats. FOSB addiction withdrawal 26655477 Quantitative immunohistochemistry was adopted to test NMDAR and FosB/ΔfosB levels during morphine withdrawal in rats. FOSB drug cocaine 26598422 Increased expression after cocaine self administration was found for 6 IEGs in dorsal and ventral striatum (c fos, Mkp1, Fosb/ΔFosb, Egr2, Egr4, and Arc) and 10 IEGs in mPFC (same 6 IEGs as in striatum, plus Bdnf, Homer1, Sgk1 and Rgs2). FOSB drug cocaine 26598422 Importantly, no major differences were found between IEG expression patterns after 10 or 60 days of cocaine self administration, except Fosb/ΔFosb in dorsal striatum and Egr2 in mPFC, whereas the amount of cocaine obtained per session was comparable for short term and long term self administration. FOSB addiction relapse 25855177 Context induced reinstatement was associated with increased expression of the immediate early genes Fos and FosB and the NMDA receptor subunit gene Grin2a in only Fos positive neurons. FOSB drug cocaine 25522720 Caudate Putamen (CPu) pERK and FosB protein levels increased after re exposure to the cocaine chamber only after conditioning with the higher cocaine dose. FOSB drug cocaine 25522720 Conversely, the higher cocaine dose, independent of environment, resulted in increased NAc FosB, ΔFosB and phosphorylated CREB (pCREB) protein levels compared to those conditioned with 5mg/kg cocaine (non CPP expressing). FOSB addiction reward 25522720 Conversely, the higher cocaine dose, independent of environment, resulted in increased NAc FosB, ΔFosB and phosphorylated CREB (pCREB) protein levels compared to those conditioned with 5mg/kg cocaine (non CPP expressing). FOSB drug cocaine 25522720 Additionally, we show distinct patterns of intracellular responses in the NAc and CPu indicating a region specific role for pERK/pCREB/FosB intracellular signaling in the retrieval of cocaine context associations. FOSB addiction addiction 25414651 Over 100 addiction/reward related genes were identified and these included: Per1, Per2, Arc, Homer2, Creb1, Grm3, Fosb, Gabrb3, Adra2a, Ntrk2, Cry1, Penk, Cartpt, Adcy1, Npy1r, Htr1a, Drd1a, Gria1, and Pdyn.

FOSB addiction reward 25143625 Of particular interest is the transcription factor ΔFosB, a truncated and stable FosB gene product whose expression in nucleus accumbens (NAc), a key reward region, is induced by chronic exposure to virtually all drugs of abuse and regulates their psychomotor and rewarding effects. FOSB addiction reward 24718372 Finally, presentation of a conditioned reward cue was found to induce striatal FosB/ΔFosB expression in WT mice, but not in KO mice, indicating a reduced stimulation of reward related brain regions in conditioned KO mice by odor presentation. FOSB drug alcohol 24355551 Withdrawal induces distinct patterns of FosB/∆FosB expression in outbred Swiss mice classified as susceptible and resistant to ethanol induced locomotor sensitization. FOSB addiction sensitization 24355551 Withdrawal induces distinct patterns of FosB/∆FosB expression in outbred Swiss mice classified as susceptible and resistant to ethanol induced locomotor sensitization. FOSB addiction withdrawal 24355551 Withdrawal induces distinct patterns of FosB/∆FosB expression in outbred Swiss mice classified as susceptible and resistant to ethanol induced locomotor sensitization. FOSB addiction addiction 24355551 Although increases in FosB/DeltaFosB expression constitute one of the most important forms of neuronal plasticity in drug addiction, it is unclear whether they represent functional or pathological plasticity. FOSB addiction withdrawal 24355551 On the 5th day of withdrawal, we could observe increased FosB/DeltaFosB expression in the EtOH_High group (in the motor cortex), in the EtOH_Low group (in the ventral tegmental area), and in both groups (in the striatum). FOSB addiction withdrawal 24355551 Furthermore, distinct patterns of FosB/DeltaFosB expression detected in sensitized and non sensitized mice seem to be more related to withdrawal period rather than to chronic drug exposure. FOSB addiction withdrawal 24355551 Finally, increases in FosB/DeltaFosB expression during withdrawal period could be considered as being due to both functional and pathological plasticity. FOSB drug opioid 24048098 At completion of behavioral testing, mu opioid receptor (OPRM1), FosB, cFos, and dopamine receptor mRNA expression was measured in the nucleus accumbens as well as OPRM1 and corticotropin releasing hormone mRNA in the paraventricular nucleus. FOSB drug amphetamine 23895375 Methamphetamine induced 3 20 fold increases of immediate early genes arc, homer 2, c fos, fosB, and its isoforms (ΔfosB and a novel isoform ΔfosB 2) in Fos positive but not Fos negative neurons. FOSB drug amphetamine 23726845 METH self administration caused increases in mRNA expression of the transcription factors, c fos and fosb, the neurotrophic factor, Bdnf, and the synaptic protein, synaptophysin (Syp) in the dorsal striatum. FOSB drug amphetamine 23726845 Importantly, ChIP PCR showed that METH self administration caused enrichment of phosphorylated CREB (pCREB), but not of histone H3 trimethylated at lysine 4 (H3K4me3), on promoters of c fos, fosb, Bdnf and Syp at 2h after cessation of drug intake. FOSB drug cocaine 23665060 CPP scores were positively correlated to NAc pERK, HIP pERK and CPu FosB protein levels, suggesting that similar to males, the ERK/CREB intracellular pathway in mesocorticolimbic regions undergoes cocaine induced neuroplasticity in female rats.

FOSB drug amphetamine 23562942 Chronic exposure to either nicotine or METH caused significant decreases in the expression of fosb, fra1, and fra2 in the nucleus accumbens (NAc) but not in the dorsal striatum whereas the drug combination increased fra2 expression in both structures. FOSB drug nicotine 23562942 Chronic exposure to either nicotine or METH caused significant decreases in the expression of fosb, fra1, and fra2 in the nucleus accumbens (NAc) but not in the dorsal striatum whereas the drug combination increased fra2 expression in both structures. FOSB drug cocaine 23447367 FosB/ΔFosB expression was increased in all groups and regions after repeated cocaine administration, although it reached lower expression levels in PA19 rats. FOSB drug cocaine 23319622 To determine the behavioral consequences of cell type specific actions of ∆FosB, we selectively overexpressed ∆FosB in D1 direct or D2 indirect MSNs in NAc in vivo and found that direct (but not indirect) pathway MSN expression enhances behavioral responses to cocaine. FOSB addiction reward 23319622 These results reveal that ∆FosB in NAc differentially modulates synaptic properties and reward related behaviors in a cell type and subregion specific fashion.

FOSB drug opioid 23185589 This study examined the role of GC in regulation of FosB/ΔFosB in both hypothalamic and extrahypothalamic brain stress systems during morphine dependence. FOSB addiction dependence 23185589 This study examined the role of GC in regulation of FosB/ΔFosB in both hypothalamic and extrahypothalamic brain stress systems during morphine dependence. FOSB drug opioid 23185589 For that, expression of FosB/ΔFosB was measured in control (sham operated) and adrenalectomized (ADX) rats that were made opiate dependent after ten days of morphine treatment. FOSB drug opioid 23185589 In sham operated rats, FosB/ΔFosB was induced after chronic morphine administration in all the brain stress areas investigated: nucleus accumbens(shell) (NAc), bed nucleus of the stria terminalis (BNST), central amygdala (CeA), hypothalamic paraventricular nucleus (PVN) and nucleus of the solitary tract noradrenergic cell group (NTS A(2)). FOSB drug opioid 23185589 Adrenalectomy attenuated the increased production of FosB/ΔFosB observed after chronic morphine exposure in NAc, CeA, and NTS. FOSB addiction addiction 23185589 These data suggest that neuroadaptation (estimated as accumulation of FosB/ΔFosB) to opiates in brain areas associated with stress is modulated by GC, supporting the evidence of a link between brain stress hormones and addiction.

FOSB drug cocaine 22836260 ΔFosB, a Fosb gene product, is induced in nucleus accumbens (NAc) and caudate putamen (CPu) by repeated exposure to drugs of abuse such as cocaine. FOSB drug cocaine 22836260 Here, we assessed whether a remote history of cocaine exposure in rats might alter inducibility of the Fosb gene elicited by subsequent drug exposure. FOSB drug cocaine 22836260 We show that prior chronic cocaine administration, followed by extended withdrawal, increases inducibility of Fosb in NAc, as evidenced by greater acute induction of ΔFosB mRNA and faster accumulation of ΔFosB protein after repeated cocaine reexposure. FOSB addiction withdrawal 22836260 We show that prior chronic cocaine administration, followed by extended withdrawal, increases inducibility of Fosb in NAc, as evidenced by greater acute induction of ΔFosB mRNA and faster accumulation of ΔFosB protein after repeated cocaine reexposure. FOSB drug cocaine 22836260 Prior chronic cocaine administration induces a long lasting increase in RNA polymerase II (Pol II) binding at the Fosb promoter in NAc only, suggesting that Pol II "stalling" primes Fosb for induction in this region upon reexposure to cocaine. FOSB drug cocaine 22836260 A cocaine challenge then triggers the release of Pol II from the gene promoter, allowing for more rapid Fosb transcription. FOSB drug cocaine 22836260 A cocaine challenge also decreases repressive histone modifications at the Fosb promoter in NAc, but increases such repressive marks and decreases activating marks in CPu. FOSB drug cocaine 22836260 These results provide new insight into the chromatin dynamics at the Fosb promoter and reveal a novel mechanism for primed Fosb induction in NAc upon reexposure to cocaine.

FOSB addiction reward 22792289 The level of FosB/ΔFosB in reward related brain regions was assessed by immunohistochemistry. FOSB drug alcohol 22792289 Additionally, FosB/ΔFosB levels in the prefrontal cortex, striatal region and the posterior region of ventral tegmental area were increased following excessive ethanol consumption, but were reduced after six day 100 Hz electroacupuncture. FOSB addiction reward 22792289 This effect of electroacupuncture may be mediated by down regulation of FosB/ΔFosB in reward related brain regions. FOSB drug cocaine 22649236 CREB and SRF are both activated in NAc by cocaine and bind to the fosB gene promoter. FOSB drug opioid 22569574 Additionally, the expression of FosB like proteins, transcription factors associated with behavioral alterations, in the nucleus accumbens of the brain was attenuated in morphine administered mice treated by ZnE.

FOSB drug alcohol 22349397 After treating juvenile and adult rats with intermittent ethanol administration, we found that ethanol treatment upregulates histone acetyl transferase (HAT) activity in adolescent prefrontal cortex and increases histone (H3 or H4) acetylation and H3(K4) dimethylation in the promoter region of cFos, Cdk5 and FosB. FOSB drug alcohol 22349397 Inhibition of histone deacetylase by sodium butyrate before ethanol injection enhances both up regulation of HAT activity and histone acetylation of cFos, Cdk5 and FosB.

FOSB addiction relapse 22266344 Regional c Fos and FosB/ΔFosB expression associated with chronic methamphetamine self administration and methamphetamine seeking behavior in rats. FOSB drug amphetamine 22266344 The regional expression of the transcription factors c Fos and FosB/ΔFosB was examined in rats given acute exposure to intravenous methamphetamine (METH) or repeated intravenous METH self administration. FOSB drug amphetamine 22266344 FosB/ΔFosB was elevated in the lateral hypothalamus, posterior ventral tegmental area, central amygdala, and dorsal raphe of all the rats with a history of METH self administration. FOSB drug amphetamine 22266344 This occurred regardless of whether they received METH on test day, suggesting presence of the long lived FosB isoform, ΔFosB. FOSB drug amphetamine 22266344 Overall, these results show persistent upregulated regional brain Fos and FosB/ΔFosB expression with chronic METH self administration and indicate a role for the lateral hypothalamus and lateral septum in METH seeking behavior.

FOSB drug nicotine 22049069 Nicotine primed the response to cocaine by enhancing its ability to induce transcriptional activation of the FosB gene through inhibition of histone deacetylase, which caused global histone acetylation in the striatum. FOSB drug cocaine 22049069 We tested this conclusion further and found that a histone deacetylase inhibitor simulated the actions of nicotine by priming the response to cocaine and enhancing FosB gene expression and LTP depression in the nucleus accumbens.

FOSB drug alcohol 22020770 To our surprise, the impairment of AP 1 activation was sufficient to mediate a severe and dose dependent phenotype in human monocytes in vitro at alcohol concentrations as low as 0.16% (or 26 mM). FOSB drug opioid 21967557 Agmatine could reduce the cyclic 3', 5' adenosine monophosphate (cAMP) overshoot at the concentration of 0.01 10 µM in the primary cultured rat hippocampal neurons and attenuated the withdrawal signals and the elevation of FosB and ΔFosB at the dose of 5 mg/kg in the morphine dependent mice.

FOSB drug opioid 21886798 Intermittent morphine pre treatment on these six pre treatment days produced a significant induction of FosB/ΔFosB, measured on day 16, in multiple brain regions including prelimbic (PL) and infralimbic (IL) cortex, nucleus accumbens (NAc) core, dorsomedial caudate putamen (CPU), basolateral amygdala (BLA) and central nucleus of the amygdala (CNA) but not in a motor cortex control region. FOSB drug opioid 21782156 Thus, c Fos, FosB/ΔFosB and P CREB immunoreactive profiles were quantified in the rat CPu after either acute or continuous (6 day) administration of morphine and/or PD168,077. FOSB drug opioid 21782156 Interestingly, at some time points, combined treatment with morphine and PD168,077 substantially increased c Fos, FosB/ΔFosB and P CREB expression.

FOSB addiction sensitization 20974185 Instead, mice of the genetically unrelated DBA/2J inbred strain expressing robust sensitization in the same protocol did not show changes in FosB/ΔFosB immunostaining throughout the striatal complex. FOSB drug amphetamine 20974185 Lack of effects in FosB/ΔFosB immunostaining was also observed in DBA/2J mice behaviorally sensitized by repeated pairings of amphetamine with the test cage. FOSB drug cocaine 20720536 In contrast, acute and repeated cocaine administrations induced hypomethylation and decreased binding of MeCP2 at the fosB promoter, and these are associated with transcriptional upregulation of fosB in NAc.

FOSB drug cocaine 20633205 The present study examined regulation of the Fos family of transcription factors, specifically cFos, FosB, and ΔFosB, in striatal subregions during and after chronic intravenous cocaine administration in self administering and yoked rats. FOSB drug cocaine 20633205 We found that cFos, FosB, and ΔFosB exhibit regionally and temporally distinct expression patterns, with greater accumulation of ΔFosB protein in the nucleus accumbens (NAc) shell and core after chronic cocaine administration, whereas ΔFosB increases in the caudate putamen (CPu) remained similar with either acute or chronic administration. FOSB drug cocaine 20633205 Interestingly, tolerance to cocaine induced cFos induction was dependent on volitional control of cocaine intake in ventral but not dorsal striatal regions, whereas regulation of FosB and ΔFosB was similar in cocaine self administering and yoked animals.

FOSB drug alcohol 19523044 To address this hypothesis in the context of substance dependence in humans, we compared the immunoreactivities of FOSB proteins in the orbitofrontal and dorsolateral prefrontal cortices (OFC and DLPFC respectively) between controls and alcoholics using semiquantitative immunoblotting. FOSB addiction dependence 19523044 To address this hypothesis in the context of substance dependence in humans, we compared the immunoreactivities of FOSB proteins in the orbitofrontal and dorsolateral prefrontal cortices (OFC and DLPFC respectively) between controls and alcoholics using semiquantitative immunoblotting. FOSB drug cocaine 19478136 During this period, under a protocol that typically induces FosB expression in the caudate nucleus, these rats and unprotected controls given only empty vector or saline were subjected to repeated twice daily injections of cocaine (30 mg/kg i.p.). FOSB drug cocaine 19478136 Immunohistochemistry of the neostriatum on day 7 showed many FosB reactive nuclei in unprotected rats but few if any in rats pretreated with active vector, which resembled rats never exposed to cocaine. FOSB drug cocaine 19478136 In contrast there was a more localized protection against cocaine elicited FosB induction when hydrolase vector was injected directly into the ventral striatum, which generated high transgene expression in many neurons of the target area. FOSB drug cocaine 19446794 Finally, we found corresponding changes in ERK1/2 activation and in accumulation of FosB/DeltaFosB, a well characterized marker for long term responses to cocaine, in MSN from these animals.

FOSB drug opioid 19324071 Differences in basal and morphine induced FosB/DeltaFosB and pCREB immunoreactivities in dopaminergic brain regions of alcohol preferring AA and alcohol avoiding ANA rats. FOSB drug opioid 19324071 These findings suggest that enhanced sensitivity of AA rats to morphine is related to augmented morphine induced expression of FosB/DeltaFosB and morphine induced reduction of pCREB levels. FOSB drug cocaine 18991842 We found that the composition of AP 1 transcription complexes and expression levels of AP 1 complexes, and several transcription factors, neurotransmitter receptors as well as intracellular signaling molecules following repeated cocaine administration are altered in Fos deficient brains. FOSB drug amphetamine 18848971 Repeated treatment with amphetamine produced HDACi like effects: enhanced global histone H4 acetylation level by Western blot as well as specific histone H4 acetylation associated with fosB promoter by chromatin immunoprecipitation in the striatum. FOSB drug cocaine 18822274 In this study, we show that a single cocaine administration (30 mg/kg) time dependently increases ERK phosphorylation, c Fos and FosB protein expression, and MKP 1 phosphorylation (p MKP 1), in the caudate putamen (CPu) and nucleus accumbens (NAc) of Fischer rats. FOSB drug cocaine 18822274 In the CPu, 1 h after cocaine injection, the increase in c Fos and FosB protein expressions is totally abolished by pre administration of DA D1 receptor antagonist, SCH23390.

FOSB drug opioid 18474394 Increased analgesic tolerance to acute morphine in fosB knock out mice: a gender study. FOSB drug opioid 18474394 We used both male and female mice lacking fosB gene to study its contribution to morphine effects. FOSB drug opioid 18474394 FosB / mice, as compared to fosB +/+ mice, developed enhanced tolerance to morphine induced analgesia. FOSB drug opioid 18474394 These results suggest that fosB may be involved in the development of tolerance to morphine analgesia but not hypothermia. FOSB drug opioid 18474394 The gender study implicates that lack of FosB proteins in female fosB / mice enhanced morphine analgesic potency. FOSB drug opioid 18474394 In conclusion, we show that fosB gene is important to analgesia but not hypothermia phenotype indicating its role in morphine effects.

FOSB drug opioid 18407360 Role of fosB in behaviours related to morphine reward and spatial memory. FOSB addiction reward 18407360 Role of fosB in behaviours related to morphine reward and spatial memory. FOSB drug opioid 18407360 Rewarding effects of morphine in fosB / mice were abolished whereas spatial learning was impaired. FOSB drug opioid 18407360 In summary, our results indicate that mice lacking fosB are less sensitive to rewarding properties of morphine and display spatial memory impairment and suggest involvement of fosB and its proteins in motivational aspects of reinforcers as well as in learning and memory processes. FOSB drug cocaine 18355967 These results indicate that AP 1 suppresses this behavioral response to cocaine. FOSB drug cocaine 18342839 In the present study, chronic mild food restriction was used as a stressor to investigate its effect on the locomotor simulant effects of cocaine as well as FosB expression in the nucleus accumbens and caudate putamen. FOSB drug opioid 18184800 In contrast to PENK, no association was detected between PDYN genotype (68 bp repeat element containing one to four copies of AP 1 binding sites in the promoter region) and heroin abuse, although there was a clear functional association with striatal PDYN mRNA expression: an increased number of inducible repeats (three and four) correlated with higher PDYN levels than adult or fetal subjects with noninducible (one and two) alleles. FOSB drug amphetamine 18184321 To test whether the behavioral phenotype is also accompanied by similar neuroplastic adaptations, the present study evaluated changes in Fos and FosB/DeltaFosB transcription factors induced in the brain of C57BL/6J mice behaviorally sensitized by repeated amphetamine or repeated restraint stress. FOSB drug cocaine 18093170 Although only 2% of striatal neurons were FosB labeled, 87% of these FosB labeled neurons were co labeled with c fos when cocaine was injected in the cocaine paired environment. FOSB drug opioid 17935891 These results demonstrate that a deficient nutritional status during the perinatal period results in adult subjects having neural alterations, leading to an increased responsiveness to morphine and/or enhanced reinforcement effects, which correlates with an overexpression of FosB in selective brain areas related to the rewarding network.

FOSB drug opioid 17592519 In contrast, microinjection of M(5) muscarinic receptor sense oligonucleotide (S ONs) into the VTA did not block the expression of behavioral sensitization or the expression of FosB in the NAc or DG in the heroin sensitized rats.

FOSB drug alcohol 17572394 Accumbal FosB/DeltaFosB immunoreactivity and conditioned place preference in alcohol preferring AA rats and alcohol avoiding ANA rats treated repeatedly with cocaine. FOSB drug cocaine 17572394 Accumbal FosB/DeltaFosB immunoreactivity and conditioned place preference in alcohol preferring AA rats and alcohol avoiding ANA rats treated repeatedly with cocaine. FOSB drug cocaine 17572394 Cocaine treatment increased the FosB/DeltaFosB immunoreactivity (IR) in the nucleus accumbens of AA rats but not in ANA rats. FOSB drug cocaine 17572394 In the caudate putamen cocaine significantly increased FosB/DeltaFosB IR, but no differences were found between the rats of two lines. FOSB drug cocaine 17572394 In conclusion, our findings show that AA rats are more sensitive to cocaine than ANA rats, and suggest that one possible mediator for this increased sensitivity could be the increased expression of fosB derived proteins in the nucleus accumbens of AA rats. FOSB drug cocaine 17560044 Elevations of FosB in the nucleus accumbens during forced cocaine abstinence correlate with divergent changes in reward function. FOSB addiction reward 17560044 Elevations of FosB in the nucleus accumbens during forced cocaine abstinence correlate with divergent changes in reward function. FOSB addiction withdrawal 17560044 At the earliest withdrawal period, these behavioral changes were accompanied by elevations in FosB like immunoreactive staining in the basolateral amygdala (BLA) and nucleus accumbens shell (NAc Sh) and core (NAc C). FOSB drug cocaine 17560044 FosB staining in all three brain areas correlated positively with cocaine preference, but negatively with novelty preference.

FOSB drug nicotine 17468183 We tested the hypothesis that a constitutive level of FosB affects nicotine regulated behaviors and comorbid behavioral traits using constitutive fosB knockout (KO) mice. FOSB drug nicotine 17468183 In wild type mice, repeated nicotine injections, but not a single acute injection, increased the expression of FosB and its truncated variant DeltaFosB in the targets but not at the origins of the mesolimbic and nigrostriatal dopamine pathways; no detectable level of FosB/DeltaFosB was found in KO mice. FOSB drug nicotine 17468183 Our results suggest that the constitutive absence of fosB has a pleiotropic influence on the behavioral effects of repeated or prolonged nicotine administration and on stress related behavioral traits in mice.

FOSB drug alcohol 17127267 Recent findings indicate that low concentrations of ethanol (10 mM) promote inflammatory processes in brain and in glial cells by up regulating cytokines and inflammatory mediators (iNOS, NO, COX 2), and by activating signaling pathways (IKK, MAPKs) and transcriptional factors (NF kappaB, AP 1) implicated in inflammatory injury. FOSB drug amphetamine 16713106 Habituation to the test cage influences amphetamine induced locomotion and Fos expression and increases FosB/DeltaFosB like immunoreactivity in mice. FOSB drug amphetamine 16713106 The present experiments tested the effects of repeated exposure to a test cage (1 h daily for four consecutive days) on amphetamine induced locomotion and Fos expression as well as on FosB/DeltaFosB like immunoreactivity in mice of the C57BL/6J and DBA/2J inbred strains that differ for the response to amphetamine, stress and novelty. FOSB drug cocaine 16674926 Acute and repeated cocaine induces alterations in FosB/DeltaFosB expression in the paraventricular nucleus of the hypothalamus. FOSB drug cocaine 16674926 In order to find a molecular mechanism of cocaine evoked effects in the PVN, in the present study, we investigated the impact of cocaine on the expression of FosB/DeltaFosB transcription factors in the PVN. FOSB drug cocaine 16674926 Using an immunohistochemical method, we found that acute cocaine treatment (25 mg/kg) induced a relatively long lasting (at least 72 h) expression of FosB/DeltaFosB in the PVN, whereas repeated cocaine administration (25 mg/kg, once daily for 5 consecutive days) caused accumulation of FosB/DeltaFosB in the PVN. FOSB drug cocaine 16674926 Using a double labeling immunofluorescent method, it was established that FosB/DeltaFosB proteins induced by repeated cocaine treatment were present in a small population of CRF immunoreactive neurons of the PVN. FOSB drug cocaine 16674926 Furthermore, it was found that pretreatment with the specific antagonist of dopamine D1 like receptors SCH 23390 (1 mg/kg) attenuated the expression and accumulation of FosB/DeltaFosB in the PVN, evoked by repeated cocaine administration. FOSB drug cocaine 16674926 Although functional consequences of the above effects for the process of addiction remain to be established, the obtained results indicate that cocaine administration can produce relatively long lasting changes in the expression of FosB/DeltaFosB transcription factors in PVN neurons (in some populations of CRF immunoreactive neurons, among others) and that dopamine D1 like receptors are involved in the above effects.

FOSB addiction withdrawal 16631212 Effects of chronic nicotine administration and its withdrawal on striatal FosB/DeltaFosB and c Fos expression in rats and mice. FOSB drug nicotine 16631212 In mice neither 2 nor 7 week oral nicotine treatment induced expression of long lived DeltaFosB isoforms although during the treatment in the NAcc FosB/DeltaFosB expression was increased as was c Fos in the CPu. FOSB drug nicotine 16631212 In rats given nicotine subcutaneously once daily for 5days FosB/DeltaFosB expression was elevated in the NAcc still after 24 h withdrawal suggesting accumulation of DeltaFosB but in the CPu neither FosB/DeltaFosB nor c Fos expression was altered. FOSB addiction withdrawal 16631212 In rats given nicotine subcutaneously once daily for 5days FosB/DeltaFosB expression was elevated in the NAcc still after 24 h withdrawal suggesting accumulation of DeltaFosB but in the CPu neither FosB/DeltaFosB nor c Fos expression was altered. FOSB drug nicotine 16631212 However, in mice given nicotine via drinking fluid although striatal fosB and c fos were activated by nicotine even after 7 week treatment no evidence of accumulation of long lived DeltaFosB was found suggesting perhaps a species difference or more likely a role for the manner of administration. FOSB drug cocaine 16380431 CREB binding protein controls response to cocaine by acetylating histones at the fosB promoter in the mouse striatum. FOSB drug cocaine 16380431 Here, we show that histone acetylation by the cAMP response element binding protein (CREB) binding protein (CBP) mediates sensitivity to cocaine by regulating expression of the fosB gene and its splice variant, DeltafosB, a transcription factor previously implicated in addiction. FOSB addiction addiction 16380431 Here, we show that histone acetylation by the cAMP response element binding protein (CREB) binding protein (CBP) mediates sensitivity to cocaine by regulating expression of the fosB gene and its splice variant, DeltafosB, a transcription factor previously implicated in addiction. FOSB drug cocaine 16380431 Using the chromatin immunoprecipitation assay with antibodies against histone H4 or CBP, we find that CBP is recruited to the fosB promoter to acetylate histone H4 in response to acute exposure to cocaine. FOSB drug cocaine 16380431 We show that mutant mice that lack one allele of the CBP gene and have normal levels of fosB expression are less sensitive to chronic (10 day) administration of cocaine than are wild type mice. FOSB drug cocaine 16263220 It has also been shown that extracellular signal regulated kinase activation can regulate cocaine induced expression of c Fos and FosB, two possible components of activator protein 1. FOSB drug cocaine 16263220 SL327 pre treatment, however, reduces the DNA binding activity of the activator protein 1 complex induced six hours after an acute cocaine treatment as well as one hour after the last of the chronic cocaine injections, a phenomenon that results from the concomitant reduction of all cocaine induced proteins (c Fos, FosB, deltaFosB, JunB). FOSB addiction intoxication 15987270 At the end of the experiment, 6 month period, or acute intoxication associated with SE induction, animals were deeply anesthetized and had their brains subjected to histologic processing for Nissl and delta FosB. FOSB drug opioid 15899480 Furthermore, agmatine inhibited the increased expression of FosB in the nucleus accumbens caused by chronic morphine.

FOSB addiction dependence 15814102 Because astrocytes interact extensively with the neurons in the brain, our data led us to conclude that oxidation regulated AP 1 target genes may represent one of the molecular mechanisms underlying neuronal adaptation associated with psychostimulant dependence. FOSB drug cocaine 15770241 These results suggest that genes encoding certain extracellular factors, membrane receptors and modulators, and intracellular signaling molecules, among others, are regulated by cocaine via the D1 receptor, and these AP 1 transcription complex regulated genes might contribute to persistent cocaine induced behavioral changes. FOSB drug amphetamine 15680202 Ginsenosides attenuate methamphetamine induced behavioral side effects in mice via activation of adenosine A2A receptors: possible involvements of the striatal reduction in AP 1 DNA binding activity and proenkephalin gene expression.

FOSB addiction withdrawal 12726824 In contrast, withdrawal from INT AMPH administration did not increase FosB expression in any of the regions examined. FOSB drug cocaine 12706249 However, expression of Deltac Jun in adult mice blocked the ability of chronic cocaine administration to induce three known targets for AP 1 in the NAc: the AMPA glutamate receptor subunit GluR2, the cyclin dependent protein kinase Cdk5, and the transcription factor nuclear factor kappaB (NFkappaB), without affecting several other proteins examined for comparison. FOSB drug cocaine 12706249 Taken together, these results provide further support for an important role of AP 1 mediated transcription in some of the behavioral and molecular mechanisms underlying cocaine addiction. FOSB addiction addiction 12706249 Taken together, these results provide further support for an important role of AP 1 mediated transcription in some of the behavioral and molecular mechanisms underlying cocaine addiction.

FOSB drug alcohol 12482856 However, only inhibition of AP 1 with dominant negative TAK1 but not NFkappaB by dominant negative IkappaBalpha significantly blunted ethanol induced increases in CD14, suggesting that AP 1 is important for CD14 transcriptional regulation.

FOSB drug cocaine 7969045 Gel retention analysis using antibodies to the various Fos and Jun proteins was used to characterize cocaine dependent alterations in the composition of striatal and cerebellar AP 1 DNA binding complexes. FOSB drug cocaine 7969045 In striatum, cocaine increases the relative levels of c Fos, Fos B, Jun B, and Jun D proteins that bind the AP 1 DNA sequence element, whereas in the cerebellum only c Fos and Jun D binding activities are increased.

HTR2C drug alcohol 10088053 Selective genotyping for the role of 5 HT2A, 5 HT2C, and GABA alpha 6 receptors and the serotonin transporter in the level of response to alcohol: a pilot study. HTR2C drug alcohol 10088053 There was no evidence that two polymorphisms of the 5 HT2A receptor gene and one of the 5 HT2C receptor gene were related to LR or alcoholism in this sample. HTR2C drug psychedelics 9924841 Most psychedelic drugs are potent agonists at 5 HT2A and 5 HT2C receptors and their binding potency to these receptors is strongly correlated with their human potency as hallucinogens. HTR2C drug alcohol 9887443 It appears from the literature that PKC plays an important role in the modulation of the function of various neurotransmitter receptors (e.g., gamma aminobutyrate type A [GABAA], N methyl D aspartate [NMDA], serotonin2A [5 HT2A], and 5 HT2C, and muscarinic [m1] receptors) resulting from ethanol exposure. HTR2C addiction aversion 9716307 Dose dependent increases in threshold for operant fear/escape responses of rats submitted to aversive stimulation of the dorsolateral periaqueductal gray (dPAG) were recorded following intraperitoneal injection of three chemically unrelated but selective 5HT2C receptor agonists (Ro 60 0175, Org 12962 and Ro 60 0332) and fluoxetine.

HTR2C drug benzodiazepine 9716307 In this paradigm which has been validated as a simulation of acute anxiety with relevance to panic disorder, the selective activation of 5HT2C receptors by Ro 60 0175, Org 12962 or Ro 60 0332 induces effects analogous to those observed following benzodiazepine receptor activation by antipanic agents such as clonazepam or alprazolam or following non selective and indirect 5HT receptor activation by fluoxetine. HTR2C drug benzodiazepine 9716307 Potency and efficacy of 5HT2C receptor agonists were intermediate between those of clonazepam and fluoxetine, indicating authentic antiaversive properties and suggesting antipanic potential for these 5HT2C receptor agonists. HTR2C drug benzodiazepine 9716307 It is also speculated that serotonin/benzodiazepine interactions existing in the brain may functionally involve the 5HT2C receptor subtypes and that the anxiogenic action reported under certain circumstances for 5HT mimetics are not mediated by 5HT2C receptor subtypes.

HTR2C drug alcohol 8788509 On the other hand, chronic ethanol treatment (60 days) significantly increased 5 HT2C receptors and 5 HT stimulated PI hydrolysis in the rat choroid plexus. HTR2C addiction reward 8587903 The results show that agents acting as full or partial agonists at 5 HT1A receptors and blockers of postsynaptic 5 HT2C receptors have anxiolytic like effects in a model of punished operant responding, whereas antagonists at 5 HT1A and 5 HT3 receptors have no such effect.

HTR2C addiction reward 7846211 Four non selective 5 HT2C/5 HT2A receptor antagonists, mianserin (2 8 mg/kg), 1 naphthyl piperazine (1 NP) (0.5 1 mg/kg), ICI 169,369 (20 mg/kg) and LY 53857 (5 mg/kg), increased punished responding for a food reward in the rat Geller Seifter test 30 min after subcutaneous (SC) administration. HTR2C addiction relapse 8032167 Ritanserin is a potent, centrally acting, highly selective 5 HT1C/2 antagonist which, in addition to having a sleep regulating and anti depression/anti axiety effect, displays a unique pharmacological action in several animal paradigms of substance abuse which assess drug craving. HTR2C drug benzodiazepine 7902543 Co administration of buspirone (5 HT1A agonist) or ondansetron (5 HT3 antagonist), but not mianserin (5 HT1C antagonist) or ketanserin (5 HT2 antagonist) with diazepam potentiated the hypersensitivity to FG 7142 following chronic treatment with diazepam. HTR2C drug alcohol 8258364 Modulation of 5 HT1C receptors and phosphoinositide system by ethanol consumption in rat brain and choroid plexus. HTR2C drug alcohol 8258364 The effect of chronic ethanol consumption (60 days) on 5 HT1C receptors as measured by [3H]mesulergine binding in the hippocampus, cortex, and choroid plexus of rats was investigated. HTR2C drug alcohol 8258364 It was observed that chronic ethanol treatment significantly increased the 5 HT stimulated [3H]inositol 1 phosphate ([3H]IP1) formation, as well as the density (Bmax) of 5 HT1C receptors without causing a significant change in affinity (KD) of [3H]mesulergine binding in rat choroid plexus. HTR2C drug alcohol 8258364 It was also observed that chronic ethanol consumption had no significant effect on the Bmax or KD of 5 HT1C receptor binding sites in the hippocampus and cortex brain regions of rats. HTR2C drug alcohol 8258364 These results thus suggest that chronic ethanol consumption causes an up regulation of both 5 HT1C receptors and 5 HT1C receptor mediated phosphoinositide hydrolysis in rat choroid plexus but has no significant effects on the 5 HT1C receptors in brain.

ARC addiction sensitization 28608416 Allergic rhino conjunctivitis (ARC) was used as a marker for allergic sensitization to define allergic asthma. ARC drug nicotine 28560653 Analysis of epidemiological factors revealed that age (P < 0.001), cast of subjects (P = 0.001), diabetes (P < 0.001), hypertension (P = 0.001), smoking habit (P = 0.01), drug abuse (P < 0.05), steroid use (P = 0.001) and body weight (P < 0.001) can influence the incidence of ARC in enrolled subjects. ARC addiction addiction 28441678 In 2014, the authors developed and launched the Addiction Recovery Clinic (ARC) to address this educational gap while also providing outpatient clinical services to patients with substance use disorders.

ARC drug cocaine 27567310 Molecular and behavioral adaptations to cocaine were studied from Arc deficient mice and their wild type littermates. ARC drug cocaine 27567310 Arc messenger RNA and proteins are rapidly induced in the striatum after acute cocaine administration, via an extracellular signal regulated kinase dependent de novo protein synthesis. ARC drug cocaine 27567310 Cocaine induces the rapid induction of Arc and its nuclear accumulation in striatal neurons.

ARC addiction sensitization 26708208 The observation that HS mice do not show increases in Arc expression with an EtOH challenge suggests the possibility that increased tolerance to the Arc inducing effects of EtOH may be a factor in behavioral sensitization. ARC drug cocaine 26598422 Increased expression after cocaine self administration was found for 6 IEGs in dorsal and ventral striatum (c fos, Mkp1, Fosb/ΔFosb, Egr2, Egr4, and Arc) and 10 IEGs in mPFC (same 6 IEGs as in striatum, plus Bdnf, Homer1, Sgk1 and Rgs2). ARC drug amphetamine 26496011 We detected six downregulated genes in the frontal cortex and the hippocampus of chronic METH treated mice, including five IEGs (Arc, Egr2, Fos, Klf10, and Nr4a1) and one neuronal receptor gene (Grm1), compared with normal saline treated group, but only four genes (Arc, Egr2, Fos, and Nr4a1) were confirmed to be different.

ARC drug cocaine 18488248 Re exposure to the environment previously associated with cocaine self administration following 22 h or 15 days of abstinence produced a significant increase in zif/268 and arc, but not c fos mRNA, in the caudate putamen and nucleus accumbens. ARC drug cocaine 18488248 With the exception of arc mRNA levels following 15 days of abstinence, all three genes were increased in the anterior cingulate cortex of animals with a cocaine history when they were re exposed to the operant chamber. ARC addiction reward 18488248 With the exception of arc mRNA levels following 15 days of abstinence, all three genes were increased in the anterior cingulate cortex of animals with a cocaine history when they were re exposed to the operant chamber. ARC drug opioid 18466961 Arc expression increased following the extinction session only in rats with a history of heroin self administration and only when tested following 1, but not 14, days of abstinence. ARC drug cocaine 18361437 Upregulation of Arc mRNA expression in the prefrontal cortex following cue induced reinstatement of extinguished cocaine seeking behavior. ARC addiction relapse 18361437 Upregulation of Arc mRNA expression in the prefrontal cortex following cue induced reinstatement of extinguished cocaine seeking behavior. ARC drug cocaine 18361437 Here we examine the hypothesis that neuronal processes associated with incentive motivational effects of cocaine cues involve increased expression of the plasticity associated gene, Arc. ARC addiction reward 18361437 Here we examine the hypothesis that neuronal processes associated with incentive motivational effects of cocaine cues involve increased expression of the plasticity associated gene, Arc. ARC drug cocaine 18361437 Cues elicited reinstatement of cocaine seeking behavior and were accompanied by increased Arc mRNA levels in the orbitofrontal, prelimbic, and anterior cingulate cortices, suggesting Arc involvement in conditioned plasticity associated with incentive motivational effects of cocaine cues. ARC addiction relapse 18361437 Cues elicited reinstatement of cocaine seeking behavior and were accompanied by increased Arc mRNA levels in the orbitofrontal, prelimbic, and anterior cingulate cortices, suggesting Arc involvement in conditioned plasticity associated with incentive motivational effects of cocaine cues. ARC addiction reward 18361437 Cues elicited reinstatement of cocaine seeking behavior and were accompanied by increased Arc mRNA levels in the orbitofrontal, prelimbic, and anterior cingulate cortices, suggesting Arc involvement in conditioned plasticity associated with incentive motivational effects of cocaine cues. ARC drug cocaine 18361437 Additionally, rats with a history of cocaine self administration and extinction exhibited upregulation of Arc expression in several limbic and cortical regions relative to saline yoked controls regardless of cue exposure condition, suggesting persistent neuroadaptations involving Arc within these regions. ARC drug alcohol 18322102 Effector immediate early gene arc in the amygdala plays a critical role in alcoholism. ARC drug alcohol 18322102 However, the role of Arc in alcoholism is unknown. ARC drug alcohol 18322102 Here, we report that the anxiolytic effects of acute ethanol were associated with increased brain derived neurotrophic factor (BDNF) and tyrosine kinase B (trkB) expression, increased phosphorylation of extracellular signal regulated kinases 1/2 (Erk1/2), Elk 1, and cAMP responsive element binding protein (CREB), increased Arc expression, and increased dendritic spine density (DSD) in both the central amygdala (CeA) and medial amygdala (MeA) but not in the basolateral amygdala (BLA) of rats. ARC drug alcohol 18322102 Conversely, the anxiogenic effects of withdrawal after long term ethanol exposure were associated with decreased BDNF and trkB expression, decreased phosphorylation of Erk1/2, Elk 1, and CREB, decreased Arc expression, and decreased DSD in both the CeA and MeA but not in the BLA of rats. ARC addiction withdrawal 18322102 Conversely, the anxiogenic effects of withdrawal after long term ethanol exposure were associated with decreased BDNF and trkB expression, decreased phosphorylation of Erk1/2, Elk 1, and CREB, decreased Arc expression, and decreased DSD in both the CeA and MeA but not in the BLA of rats. ARC drug alcohol 18322102 We also showed that BDNF infusion into the CeA normalized phosphorylation of Erk1/2, Elk 1, and CREB, and normalized Arc expression, thereby protecting against the onset of ethanol withdrawal related anxiety. ARC addiction withdrawal 18322102 We also showed that BDNF infusion into the CeA normalized phosphorylation of Erk1/2, Elk 1, and CREB, and normalized Arc expression, thereby protecting against the onset of ethanol withdrawal related anxiety. ARC drug alcohol 18322102 We further demonstrated that arresting Arc expression in the CeA decreased DSD, thereby increasing anxiety like and alcohol drinking behaviors in control rats. ARC drug alcohol 18322102 These results revealed that BDNF Arc signaling and the associated DSD in the CeA, and possibly in the MeA, may be involved in the molecular processes of alcohol dependence and comorbidity of anxiety and alcohol drinking behaviors. ARC addiction dependence 18322102 These results revealed that BDNF Arc signaling and the associated DSD in the CeA, and possibly in the MeA, may be involved in the molecular processes of alcohol dependence and comorbidity of anxiety and alcohol drinking behaviors. ARC drug cocaine 18311559 Rats self administered cocaine or received yoked saline for 2 h/day for 10 days followed by 22 h or 2 weeks of abstinence when they were re exposed to the self administration chamber with or without levers available to press for 1 h. Brains were harvested and sections through the prefrontal cortex were processed for in situ hybridization using radioactive oligonucleotide probes encoding c fos, zif/268, arc, and bdnf. ARC drug opioid 18157469 The present study was undertaken to investigate the effect of melatonin on the content of β endorphin (β EP) in the hypothalamic arcuate nucleus (Arc) and periaqueductal grey (PAG) of midbrain in morphine withdrawal mice. ARC addiction withdrawal 18157469 The present study was undertaken to investigate the effect of melatonin on the content of β endorphin (β EP) in the hypothalamic arcuate nucleus (Arc) and periaqueductal grey (PAG) of midbrain in morphine withdrawal mice. ARC drug opioid 18157469 The results suggest that MEL increases the content of β EP in the PAG of midbrain, decrease the content of β EP in the Arc in morphine withdrawal mice. ARC addiction withdrawal 18157469 The results suggest that MEL increases the content of β EP in the PAG of midbrain, decrease the content of β EP in the Arc in morphine withdrawal mice. ARC addiction relapse 17959795 Arcuate nucleus (Arc) injections of PYY3 36 (0.4 microg per side) decreased pellet priming induced reinstatement. ARC addiction relapse 17959795 The attenuation of pellet priming induced reinstatement by systemic PYY3 36 was reversed by systemic (2 mg/kg) but not Arc (0.5 microg per side) injections of the Y2 receptor antagonist BIIE0246. ARC addiction relapse 17959795 Arc PYY3 36 injections did not decrease pellet cue induced reinstatement. ARC addiction relapse 17959795 These data identify an effect of systemic PYY3 36 on relapse to food seeking that is independent of Y2 receptor activation in Arc and suggest that PYY3 36 should be considered for the treatment of relapse to maladaptive food taking habits during dieting. ARC drug opioid 17600376 The galanin induced increases in HWLs were inhibited by injection of 10 microg of the opioid receptor antagonist naloxone or 1 nmol of the mu opioid receptor antagonist beta funaltrexamine (beta FNA) into PAG, suggesting that the antinociceptive effects induced by intra ARC injection of galanin occur via the neural pathway from ARC to PAG. ARC drug amphetamine 17499349 Effects of SKF 38393, a dopamine D1 receptor agonist on expression of amphetamine induced behavioral sensitization and expression of immediate early gene arc in prefrontal cortex of rats. ARC addiction sensitization 17499349 Effects of SKF 38393, a dopamine D1 receptor agonist on expression of amphetamine induced behavioral sensitization and expression of immediate early gene arc in prefrontal cortex of rats. ARC drug amphetamine 17499349 We examined whether a dopamine D1 agonist can reverse behavioral sensitization once established by repeated amphetamine (AMP) administrations and determined the mRNA expression levels of the D1 and D2 receptors, metabotropic glutamate receptor 1 (mGluR1), and activity regulated cytoskeleton associated protein (arc) in rats. ARC addiction sensitization 17499349 We examined whether a dopamine D1 agonist can reverse behavioral sensitization once established by repeated amphetamine (AMP) administrations and determined the mRNA expression levels of the D1 and D2 receptors, metabotropic glutamate receptor 1 (mGluR1), and activity regulated cytoskeleton associated protein (arc) in rats. ARC drug amphetamine 17499349 We examined whether a dopamine D1 agonist can reverse behavioral sensitization once established by repeated amphetamine (AMP) administrations and determined the mRNA expression levels of the D1 and D2 receptors, metabotropic glutamate receptor 1 (mGluR1), and activity regulated cytoskeleton associated protein (arc) in rats. ARC addiction sensitization 17499349 We examined whether a dopamine D1 agonist can reverse behavioral sensitization once established by repeated amphetamine (AMP) administrations and determined the mRNA expression levels of the D1 and D2 receptors, metabotropic glutamate receptor 1 (mGluR1), and activity regulated cytoskeleton associated protein (arc) in rats. ARC addiction sensitization 17499349 There was no significant difference in arc expression level between the saline and SKF treatment groups after the AMP challenge, suggesting that arc expression level is not involved in the reversal effects of SKF in AMP sensitization. ARC drug amphetamine 17049170 Neurotoxic AMPH pretreatment resulted in significantly diminished AMPH challenge induced mRNA increases of activity regulated cytoskeletal protein (ARC), nerve growth factor inducible protein A (NGFI A), and nerve growth factor inducible protein B (NGFI B) in the parietal cortex while neither saline pretreatment nor non neurotoxic AMPH pretreatment did. ARC drug amphetamine 17049170 In the striatum, there were no differences between saline, neurotoxic AMPH, and non neurotoxic AMPH pretreatments on ARC, NGFI A or NGFI B expression elicited by the AMPH challenge. ARC drug amphetamine 16218999 Withdrawal of the obesogenic diets decreased gene expression for cocaine and amphetamine regulated transcript (CART) and dynorphin (DYN) in the arcuate nucleus (ARC), and DYN and brain derived neurotrophic factor (BDNF) in the VMH, whereas neuropeptide Y (NPY) gene expression in the ARC was increased. ARC drug cocaine 16218999 Withdrawal of the obesogenic diets decreased gene expression for cocaine and amphetamine regulated transcript (CART) and dynorphin (DYN) in the arcuate nucleus (ARC), and DYN and brain derived neurotrophic factor (BDNF) in the VMH, whereas neuropeptide Y (NPY) gene expression in the ARC was increased. ARC addiction withdrawal 16218999 Withdrawal of the obesogenic diets decreased gene expression for cocaine and amphetamine regulated transcript (CART) and dynorphin (DYN) in the arcuate nucleus (ARC), and DYN and brain derived neurotrophic factor (BDNF) in the VMH, whereas neuropeptide Y (NPY) gene expression in the ARC was increased. ARC drug opioid 16211563 Morphine activates Arc expression in the mouse striatum and in mouse neuroblastoma Neuro2A MOR1A cells expressing mu opioid receptors. ARC drug opioid 16211563 In the present experiments, the influence of morphine on Arc expression was assessed by quantitative reverse transcription real time PCR and Western blotting in vivo in the mouse striatum/nucleus accumbens and, in vitro, in the mouse Neuro2A MOR1A cell line, expressing mu opioid receptor. ARC drug opioid 16211563 An acute administration of morphine produced a marked increase in Arc mRNA and protein level in the mouse striatum/nucleus accumbens complex. ARC drug opioid 16211563 After prolonged opiate treatment, tolerance to the stimulatory effect of morphine on Arc expression developed. ARC drug opioid 16211563 No changes in the striatal Arc mRNA levels were observed during spontaneous or opioid antagonist precipitated morphine withdrawal. ARC addiction withdrawal 16211563 No changes in the striatal Arc mRNA levels were observed during spontaneous or opioid antagonist precipitated morphine withdrawal. ARC drug opioid 16211563 In Neuro2A MOR1A cells, acute, but not prolonged, morphine treatment elevated Arc mRNA level by activation of mu opioid receptor. ARC drug opioid 16211563 Inhibition experiments revealed that morphine induced Arc expression in Neuro2A MOR1A cells via intracellular signaling pathways involving mitogen activated protein (MAP) kinases and protein kinase C. These results lend further support to the notion that stimulation of opioid receptors may exert an activating influence on some intracellular pathways and leads to induction of immediate early genes. ARC drug opioid 16211563 They also demonstrate that Arc is induced in the brain in vivo after morphine administration and thus may play a role in neuroadaptations produced by the drug. ARC drug cocaine 16123776 Consistent with these behavioral findings, we found that cocaine regulation of gene expression in striatum, including the acute induction of the immediate early genes c fos and arc (activity regulated cytoskeletal associated gene), was abolished in DARPP 32 Thr 34 mutants, but not in Thr 75 mutants. ARC drug nicotine 16084664 Differential expression of arc mRNA and other plasticity related genes induced by nicotine in adolescent rat forebrain. ARC drug nicotine 16084664 To investigate this question, we examined the expression of a number of early response genes (arc, c fos and NGFI B) that have been implicated in synaptic plasticity and addiction, following acute nicotine in adolescent and adult rats. ARC addiction addiction 16084664 To investigate this question, we examined the expression of a number of early response genes (arc, c fos and NGFI B) that have been implicated in synaptic plasticity and addiction, following acute nicotine in adolescent and adult rats. ARC drug nicotine 16084664 Following acute nicotine treatment (0.1, 0.4mg/kg), we found a marked induction of arc mRNA in the prefrontal cortex of nicotine treated adolescents compared with a less pronounced increase of arc in the adult. ARC drug nicotine 16084664 In contrast, nicotine induced less arc, c fos, and NGFI B expression in the somatosensory cortex of adolescents compared with adults. ARC drug cannabinoid 15901756 The present study sought to determine whether cannabinoids modulate A type K(+) currents (I(A)) in neurons of the hypothalamic arcuate nucleus (ARC). ARC drug cannabinoid 15901756 Collectively, these data reveal that guinea pig ARC neurons, including proopiomelanocortin neurons, express a prominent I(A) that is positively modulated by cannabinoids in a sex specific way by altering the voltage dependence of its inactivation. ARC addiction dependence 15901756 Collectively, these data reveal that guinea pig ARC neurons, including proopiomelanocortin neurons, express a prominent I(A) that is positively modulated by cannabinoids in a sex specific way by altering the voltage dependence of its inactivation. ARC drug opioid 15849022 Recent gene expression profiling studies reveal additional clusters of morphine responsive genes: whereas single dose administration has been shown to predominantly reduce expression of genes involved in metabolic function, ascending morphine doses leading to morphine tolerance revealed induction of genes which alter patterns of synaptic connectivity such as arc or ania 3. ARC drug nicotine 15705350 We found that increasing the rate of intravenous nicotine infusion potentiated its ability to produce locomotor sensitization, and to induce c fos and arc mRNA expression in mesocorticolimbic structures. ARC addiction sensitization 15705350 We found that increasing the rate of intravenous nicotine infusion potentiated its ability to produce locomotor sensitization, and to induce c fos and arc mRNA expression in mesocorticolimbic structures. ARC drug opioid 15544839 We showed that the antinociceptive effect induced by intra ARC injection of galanin was dose dependently attenuated by the following intra ARC injection of naloxone. ARC drug opioid 15544839 Furthermore, intra ARC administration of the selective mu opioid receptor antagonist beta funaltrexamine (beta FNA) attenuated the increased HWL induced by intra ARC injection of galanin in a dose dependent manner, while the delta opioid receptor antagonist naltrindole or the kappa opioid receptor antagonist nor binaltorphimine (nor BNI) did not. ARC drug opioid 15544839 Moreover, intra ARC injection of a galanin receptor antagonist galantide attenuated intraperitoneal morphine induced increases in HWLs. ARC drug opioid 15544839 These results demonstrate that the antinociceptive effect of galanin was related to the opioid system, especially mu opioid receptor was involved in, and that systemic morphine induced antinociception involves galanin in the ARC. ARC drug cocaine 15254092 Rapid infusions potentiated the ability of cocaine to block DA reuptake, to induce c fos and arc mRNA expression, especially in mesocorticolimbic regions, and to produce psychomotor sensitization. ARC addiction sensitization 15254092 Rapid infusions potentiated the ability of cocaine to block DA reuptake, to induce c fos and arc mRNA expression, especially in mesocorticolimbic regions, and to produce psychomotor sensitization. ARC drug amphetamine 12890524 When given in a novel test environment amphetamine produces greater levels of c fos and arc mRNA expression in many brain regions relative to when it is given in the home cage. ARC drug opioid 12855314 Intra ARC injection of naloxone had no significant influence on the HWL to thermal and mechanical stimulation in intact rats. ARC drug opioid 12855314 The HWL decreased significantly after intra ARC injection of 1 or 10 microg of naloxone in rats with inflammation, but not with 0.1 microg of naloxone. ARC drug opioid 12855314 Furthermore, intra ARC administration of the selective mu opioid receptor antagonist beta funaltrexamine (beta FNA) decreased the nociceptive response latencies to both stimulation in a dose dependent manner in rats with inflammation, while intra ARC administration of the selective delta opioid receptor antagonist naltrindole or the selective kappa opioid receptor antagonist nor binaltorphimine (nor BNI) showed no influences on the nociceptive response latency. ARC drug opioid 12855314 The results indicate that endogenous beta endorphin in the ARC plays an important role in the endogenous antinociceptive system in rats with inflammation, and that its effect is predominantly mediated by the mu opioid receptor. ARC addiction withdrawal 12784103 In contrast, Arc, another 'effector' IEG, was not induced by opiate withdrawal. ARC drug amphetamine 12774298 Differential regulation by stimulants of neocortical expression of mrt1, arc, and homer1a mRNA in the rats treated with repeated methamphetamine. ARC drug cocaine 12774298 In contrast, the basal expression of other stimulant inducible and plasticity related genes arc and homer1a and the ability of MAP or cocaine challenge to augment the amounts of their transcripts were not affected by the repeated MAP regimen in the cortical area. ARC addiction sensitization 12774298 These findings suggest the differential regulation by stimulant of neocortical mrt1, arc, and homer1a expression in the behaviorally sensitized animals and supports the view that stimulant induction of mrt1 may be involved in the early molecular signalings for stimulant sensitization. ARC drug cocaine 12687634 Many genes upregulated in the CPu by cocaine were immediate early genes for transcription factors and for "effector" proteins (e.g., vesl/Homer1a, Arc, synaptotagmin IV). ARC addiction sensitization 12642909 synaptophysin, stathmin and arc), synaptogenesis, neuritic sprouting and elongation must develop during behavioral sensitization. ARC drug amphetamine 12638131 Using these criteria, the mRNA for three immediate early genes (IEGs), coding for activity regulated cytoskeletal associated protein (Arc), nerve growth factor induced protein A (NGFI A; early growth response protein 1) and nerve growth factor induced protein B (NGFI B), were upregulated 1 and 3 h after amphetamine as previously described. ARC drug alcohol 12130710 No effects were seen in alcohol induced c Fos after the pretreatment of 20 mg/kg propranolol (beta adrenoceptor antagonist), 10 mg/kg 2 (2 (4 (2 methoxyphenyl)piperazin 1 yl) ethy) 4,4 dimethyl 1,3 (2H,4H) isoquinolindione dihydrochloride (ARC 239) (alpha(2B/C) adrenoceptor antagonist), or 30 mg/kg naltrexone (opioid antagonist). ARC drug opioid 12130710 No effects were seen in alcohol induced c Fos after the pretreatment of 20 mg/kg propranolol (beta adrenoceptor antagonist), 10 mg/kg 2 (2 (4 (2 methoxyphenyl)piperazin 1 yl) ethy) 4,4 dimethyl 1,3 (2H,4H) isoquinolindione dihydrochloride (ARC 239) (alpha(2B/C) adrenoceptor antagonist), or 30 mg/kg naltrexone (opioid antagonist). ARC drug cocaine 12117546 Protein levels of protein tyrosine kinase 2 (PYK2), activity regulated cytoskeletal protein (ARC), as well as an antigen related to nerve growth factor I B (NGFI B RA) were shown to be significantly induced after cocaine administration. ARC drug amphetamine 12105085 The mRNA of arc, an activity regulated protein associated with cytoskeleton, but not of alpha tubulin, as markers for neuritic elongation, showed robust increases in the striatum, hippocampus, and cortices after a single dose of methamphetamine. ARC drug amphetamine 12105085 Synaptophysin and stathmin mRNAs did not increase again after chronic methamphetamine administration, whereas the increases in arc, MKP 1, and MKP 3 mRNAs persisted in the brain regions after chronic methamphetamine administration. ARC drug amphetamine 11879792 The ability of amphetamine to evoke arc (Arg 3.1) mRNA expression in the caudate, nucleus accumbens and neocortex is modulated by environmental context. ARC drug amphetamine 11879792 The purpose of this study was to determine if environmental context has a similar effect on the ability of amphetamine to induce the expression of arc (also known as Arg 3.1), an "effector" immediate early gene (IEG) thought to play a direct role in cellular plasticity. ARC drug amphetamine 11879792 In the prefrontal cortex, caudate putamen and core of the nucleus accumbens, amphetamine significantly increased arc mRNA expression under both conditions, but the level of expression was significantly enhanced when amphetamine was given in a distinct environment. ARC drug amphetamine 11879792 In the shell of the nucleus accumbens amphetamine significantly increased the expression of arc mRNA only when it was administered in the distinct environment. ARC drug amphetamine 11879792 Thus, the ability of amphetamine to induce the expression of arc varies as a function of the environmental context in which it is administered. ARC drug amphetamine 11400323 Arc protein is an "effector protein" and markedly induced by convulsion or methamphetamine. ARC addiction sensitization 11233297 2) Research on neural plasticity related sensitization revealed the involvement of several molecules such as tissue plasminogen activator, arc (activity regulated, cytoskeleton associated), synaptophysin and stathmin. ARC drug amphetamine 9689478 A robust increase in expression of arc gene, an effector immediate early gene, in the rat brain after acute and chronic methamphetamine administration. ARC drug amphetamine 9689478 The effect of acute and chronic administration of methamphetamine (METH) on the levels of activity regulated cytoskeleton associated protein (arc), an effector immediate early gene, mRNA has been investigated in rat brain using in situ hybridization. ARC drug amphetamine 9689478 The effect of acute and chronic administration of methamphetamine (METH) on the levels of activity regulated cytoskeleton associated protein (arc), an effector immediate early gene, mRNA has been investigated in rat brain using in situ hybridization. ARC drug amphetamine 9689478 Levels of arc mRNAs in the brain regions examined increased significantly from 0.5 1 h after an acute METH (4 mg/kg) administration compared with basal levels. ARC drug amphetamine 9689478 The increase in arc mRNA continued by 3 h, and then subsided to basal levels by 6 h. The degree of increase in arc mRNA and the peak time after METH administration varied according to brain area. ARC drug amphetamine 9689478 Arc mRNA in cerebral cortices showed robust increase 1 h after METH administration. ARC drug amphetamine 9689478 Microscopic examination revealed that the METH induced arc mRNAs in the parietal cortex were enriched in layers IV and VI, and those in the striatum existed mainly in the medium sized neuron. ARC drug amphetamine 9689478 Pretreatment with either 0.5 mg/kg SCH23390 or 0.25 mg/kg MK 801 almost completely blocked the enhanced striatal arc mRNA levels induced by acute METH administration, whereas such pretreatments only partially reduced the effect of METH in the cerebral cortical regions. ARC drug amphetamine 9689478 In the chronic treatment experiment, the arc mRNA levels of the group that received chronic treatment with METH followed by a METH challenge showed an increase like seen after acute METH administration. ARC drug amphetamine 9689478 Since previous studies proposed that arc is one of cytoskeleton associated proteins and is selectively localized in neural dendrites, the results of the present study suggested that arc may play an important role in the synaptic plasticity underlying METH induced adaptational changes including behavioral sensitization. ARC addiction sensitization 9689478 Since previous studies proposed that arc is one of cytoskeleton associated proteins and is selectively localized in neural dendrites, the results of the present study suggested that arc may play an important role in the synaptic plasticity underlying METH induced adaptational changes including behavioral sensitization.

ARC drug opioid 9472985 Supported by studies using an opioid receptor agonist (morphine) and antagonist (naloxone), these observations demonstrate that ARC derived (beta END) neurons modulate the responses of PVN neurons to DEX. ARC drug opioid 8613967 The membrane hyperpolarization to DAMGO ([D Ala2, N Me Phe4, Gly ol5] enkephalin) in beta endorphin and other arcuate (ARC) neurons was investigated in hypothalamic slices from control and morphine treated, ovariectomized guinea pigs. ARC drug opioid 8613967 Chronic morphine treatment caused both a decreased potency (EC50 220 +/ 10 nM vs. 64 +/ 3 nM in controls) and a decreased efficacy (Vmax: 7.1 +/ 1.1 mV vs. 10.7 +/ 0.6 mV in controls) of DAMGO in a population of ARC neurons including beta endorphin neurons. ARC drug opioid 8613967 In another population of ARC neurons from morphine treated animals, DAMGO was less potent (EC50: 110 +/ 4 nm) than in controls (EC50: 64 +/ 3nM), but there was not a significant change in the efficacy of DAMGO. ARC drug opioid 8613967 The density of mu opioid receptors labeled with the antagonist radioligand [3H]diprenorphine was found to be significantly decreased in the ARC and surrounding mediobasal hypothalamus after morphine treatment (Bmax: 217 +/ 9 vs. 276 +/ 16 fmol/mg protein in controls), which is consistent with the altered response in beta endorphin neurons. ARC drug opioid 8613967 In summary, chronic morphine treatment decreases mu opioid receptor density and the functional coupling of mu opioid receptors to K+ channels in ARC neurons. ARC drug opioid 8613967 This expression of morphine tolerance by beta endorphin (ARC) neurons may serve as a homeostatic mechanism to maintain opioid control of a variety of systems ranging from reproduction to motivation and reward.

CNR1 drug alcohol 32738384 We have closely monitored the critical indicators reflecting changes of ECS during the whole process from alcohol absorption to its metabolization after acute alcohol (4.5 g/kg) intake by intragastric administration, including two key endocannabinoids (AEA and 2 AG) and their hydrolytic enzymes (FAAH and MAGL), as well as two crucial receptors (CB1R and CB2R) of ECS in blood and three brain regions.

CNR1 drug cannabinoid 26223500 In this study, the authors provide evidence that congenitally enhanced endocannabinoid levels in the neuronal circuits underlying anxiety like behavioral states (mainly medial prefrontal cortex, amygdala and hippocampus) lead to CB1R desenistization and anxiety and depression. CNR1 drug cannabinoid 26223500 These findings may have potential relevance to the understanding of the neurochemical effects of chronic CB1R overstimulation in cannabis abusers. CNR1 drug cannabinoid 26191005 During this time, the four groups for each age (i.e., intact/saline, intact/THC, OVX/saline, and OVX/THC) were trained in a learning and performance procedure and dose effect curves were established for Δ(9) THC (0.56 56 mg/kg) and the cannabinoid type 1 receptor (CB1R) antagonist rimonabant (0.32 10 mg/kg). CNR1 drug cannabinoid 26191005 Hippocampal protein expression of CB1R, AHA1 (a co chaperone of CB1R) and HSP90β (a molecular chaperone modulated by AHA 1) was affected more by OVX than chronic Δ(9) THC; striatal protein expression was not consistently affected by either manipulation. CNR1 drug alcohol 26123153 For example, chronic exposure to ethanol, in either cell culture or preclinical rodent models, causes an increase in endocannabinoid levels that results in down regulation of the cannabinoid receptor 1 (CB1) and uncoupling of this receptor from downstream G protein signaling pathways.

CNR1 drug cannabinoid 25942289 Here, we reported that a single in vivo morphine exposure (SM) did not affect inhibitory long term depression (I LTD) in the hippocampus, compared with saline control; while repeated morphine exposure (RM) abolished this I LTD. Interestingly, opioid withdrawal for 3 5 days after repeated (RMW), but not a single morphine exposure (SMW), largely enhanced I LTD. More importantly, the I LTD in single morphine treatment is dependent on presynaptic mechanism since it can be blocked by AM251, a selective cannabinoid receptor 1 antagonist.

CNR1 drug cannabinoid 25510937 Disturbances in cannabinoid type 1 receptor (CB1R) signaling have been linked to emotional and cognitive deficits characterizing neuropsychiatric disorders, including schizophrenia. CNR1 addiction reward 25510937 Furthermore, using a conditioned place preference procedure and a social interaction test, we report that intra vHipp CB1R activation potentiates the reward salience of normally sub threshold conditioning doses of opiates and induces deficits in natural sociability and social recognition behaviors.

CNR1 drug cannabinoid 25088915 In the present study, we investigated whether treatment with the selective cannabinoid receptor 1 (CB1) agonist arachidonyl 2' chloroethylamide (ACEA) affects NGF induced sensitization of TRPV1 in adult mouse dorsal root ganglion (DRG) afferent neurons.

CNR1 drug cannabinoid 25081244 Since type 1 cannabinoid receptors (CB1Rs), expressed in many brain areas including the mPFC, can modulate excitatory and inhibitory neurotransmission, we aimed to determine whether CB1R activation results in modifications of the E/I balance. CNR1 drug cannabinoid 25081244 By decomposing the synaptic response evoked by layer I stimulation into its excitatory and inhibitory components, we show that in vitro CB1R activation with the cannabinoid receptor agonists WIN55,212 2 (WIN) and CP 55940 (CP) modulates the balance between excitation and inhibition (E/I balance) of layer II/III pyramidal neurons. CNR1 drug cannabinoid 25081244 This modulation of the E/I balance by CB1Rs may thus be fundamental in the regulation of local PL cortical network excitability and could be the mechanism through which excessive CB1R activation (cannabis abuse) affects cognitive functions. CNR1 drug cannabinoid 25064144 On the contrary, while the CB1R antagonist SR141716 per se did not affect the population spike, it did worsen KA induced bursts, confirming increased eCB tone upon KA treatment.

CNR1 drug cannabinoid 24152087 Our results suggest that, although the performance of GG subjects was at normal levels, a lower efficiency of the endocannabinoid system, probably due to a lowered expression of CB1R, produced a reduction in the performance of these subjects when attentional control and working memory processing is challenged.

JUN drug cocaine 7969045 The work described here compares cocaine induced transcriptional regulation of immediate early gene mRNA levels, as well as AP 1 DNA binding activity, within the striatum and cerebellum. JUN drug cocaine 7969045 In the striatum, acute cocaine administration increases cellular levels of c fos and jun B mRNA, whereas transcriptional effects in the cerebellum are limited to c fos mRNA. JUN drug cocaine 7969045 Gel retention analysis using antibodies to the various Fos and Jun proteins was used to characterize cocaine dependent alterations in the composition of striatal and cerebellar AP 1 DNA binding complexes. JUN drug cocaine 7969045 Gel retention analysis using antibodies to the various Fos and Jun proteins was used to characterize cocaine dependent alterations in the composition of striatal and cerebellar AP 1 DNA binding complexes. JUN drug cocaine 7969045 In striatum, cocaine increases the relative levels of c Fos, Fos B, Jun B, and Jun D proteins that bind the AP 1 DNA sequence element, whereas in the cerebellum only c Fos and Jun D binding activities are increased. JUN drug cocaine 7969045 In striatum, cocaine increases the relative levels of c Fos, Fos B, Jun B, and Jun D proteins that bind the AP 1 DNA sequence element, whereas in the cerebellum only c Fos and Jun D binding activities are increased.

JUN drug alcohol 8974322 The expression of the proteins (C FOS and C JUN) encoded by the immediate early genes c fos and c jun was investigated in the brains of rats undergoing ethanol withdrawal. JUN addiction withdrawal 8974322 The expression of the proteins (C FOS and C JUN) encoded by the immediate early genes c fos and c jun was investigated in the brains of rats undergoing ethanol withdrawal. JUN addiction withdrawal 8974322 Both proteins were induced in the cerebral cortex, the piriform cortex, the olfactory bulb, the inferior colliculus, the granular cell layer of the cerebellum and in the brain stem, but only C JUN was induced in the hippocampus of animals undergoing withdrawal without overt seizures. JUN addiction withdrawal 8974322 Maximal C FOS expression occurred 15 hr after withdrawal while C JUN was maximal at 24 hr. JUN addiction withdrawal 8974322 Gel shift assays indicated the formation of AP 1 binding factors in nuclear extracts of the cerebral cortex, hippocampus and cerebellum 15 and 17 hr after withdrawal. JUN addiction withdrawal 19912955 A large, transient increase in the expression of whole brain c fos, c jun, and zif/268 mRNA was observed 12 h after withdrawal, and expression of their protein products was detected 15 to 24 h after withdrawal. JUN addiction withdrawal 19912955 All three proteins were present in the cerebral cortex, the olfactory bulb, the inferior colliculus, the granular cell layer of the cerebellum, and in the brain stem, but only C JUN and ZIF/268 were detected in the hippocampus of animals undergoing withdrawal without overt seizures. JUN drug cocaine 8385579 The investigations have focused on the Fos Jun family of immediate early gene transcription factors, and the CREB family of transcription factors, as possible mediators of the effects of chronic opiate and cocaine exposure on regulation of neuronal gene expression. JUN drug cocaine 1631058 Regulation of immediate early gene expression and AP 1 binding in the rat nucleus accumbens by chronic cocaine. JUN drug cocaine 1631058 We therefore examined changes in the mRNA levels for the IEGs c fos, c jun, fosB, junB, and zif268 in the NAc of rats treated acutely and chronically with cocaine. JUN drug cocaine 1631058 As would be expected from the RNA data and immunohistochemistry, acute cocaine administration increased AP 1 binding activity in the NAc, an effect that reverted completely to control levels within 8 12 hr. JUN drug cocaine 1631058 In contrast, AP 1 binding activity in the NAc of animals treated chronically with cocaine remained elevated at acute levels 18 hr after the last chronic injection, a time at which c fos and c jun mRNA levels and Fos like immunoreactivity had returned to control values. JUN drug cocaine 1631058 In contrast, AP 1 binding activity in the NAc of animals treated chronically with cocaine remained elevated at acute levels 18 hr after the last chronic injection, a time at which c fos and c jun mRNA levels and Fos like immunoreactivity had returned to control values. JUN drug cocaine 1631058 An additional acute cocaine challenge did not further increase AP 1 binding. JUN drug cocaine 1631058 The data suggest that chronic cocaine treatment leads to a persistent increase in AP 1 binding activity, which may be involved in some of the physiological and behavioral aspects of cocaine addiction. JUN addiction addiction 1631058 The data suggest that chronic cocaine treatment leads to a persistent increase in AP 1 binding activity, which may be involved in some of the physiological and behavioral aspects of cocaine addiction. JUN addiction withdrawal 1701330 In the LC and some other brain regions, induction of c fos during opiate withdrawal was associated with a parallel induction of c jun, another nuclear proto oncogene, which, like c fos, is expressed rapidly in brain in response to certain extracellular stimuli. CASP3 drug opioid 32524520 The morphine induced increases of apoptosis, neuron death, OS, lipid peroxidation, caspase 3 and caspase 9, neuroinflammatory cytokines (IL 1β, TNF α, IL 6), and Ca2+ levels in the hippocampal neuron of TRPM2 WT mouse were decreased by the L NAME, ACA, and 2 APB treatments, although cell viability, neuron count, and reduced glutathione and glutathione peroxidase levels were increased by the treatments. CASP3 drug amphetamine 32450188 Inhibition of circHomer1 expression indeed alleviated METH induced neurotoxicity, with lower apoptosis rate via flow cytometry and cleaved Caspase3 protein level. CASP3 drug amphetamine 32120831 Moreover, diminished expression of anti apoptotic proteins, including Bcl 2, Caspase3, Caspase7, and Caspase8 in METH exposed SH SY5y cells, was significantly recovered by treatment with lupenone. CASP3 drug amphetamine 32086884 In addition, to explore METH induced neurotoxicity, we measured the level of Parkin and the phosphorylation levels of α syn, Polo like kinase 2 (PLK2), the proteasome activity marker CD3δ, and the apoptosis related proteins Caspase 3 and PARP. CASP3 drug amphetamine 32035215 Results further showed that luteolin pretreatment significantly repressed the METH induced increases of PI3K, Akt, p Akt, p53, Bax, caspase 3, normalized the ratio of p Akt/Akt, and autophagy related proteins (Beclin1, Atg5 and LC3 II) expression. CASP3 drug alcohol 31984446 Western blot testing indicated elevated levels of caspase 3/cleaved caspase 3, NF kB, and PKC/pPKC proteins in the cerebella of ethanol treated animals. CASP3 drug amphetamine 31928234 FIHMI significantly attenuated the METH caused cell damage in 661W cells, evidenced by increasing cell viability and mitochondrial membrane potential, decreasing cytochrome c release and DNA fragmentation, inhibiting activities of caspase 3/9, and changing expression of apoptosis related protein.

CASP3 addiction withdrawal 31911195 Of the altered proteins, CASP3, LCMT2, GRIN2D, CCNT2, FADS3 and MRPS18B were inversely changed in response to nicotine and withdrawal, coincidence with the change of body weight. CASP3 drug nicotine 31911195 Further Western blot and RT qPCR analyses confirmed that the levels of the 4 proteins CASP3, LCMT2, GRIN2D and CCNT2, instead of their mRNA transcripts, altered in response to nicotine and withdrawal. CASP3 addiction withdrawal 31911195 Further Western blot and RT qPCR analyses confirmed that the levels of the 4 proteins CASP3, LCMT2, GRIN2D and CCNT2, instead of their mRNA transcripts, altered in response to nicotine and withdrawal. CASP3 drug nicotine 31911195 Through TMT based proteomic analysis, this study identified differential hypothalamic protein profiles in response to nicotine treatment and its withdrawal, and 4 nicotine and withdrawal induced contrary proteins CASP3, LCMT2, GRIN2D and CCNT2 are involved in several enriched GO terms and KEGG pathways, which are associated with cell apoptosis, neurotransmission and metabolism.

CASP3 drug amphetamine 31396089 Ad libitum HRW consumption also had an inhibitory effect on the METH induced increase in the expression of Bax/Bcl 2, cleaved caspase 3, glucose related protein 78 (GRP 78), CCAAT/enhancer binding protein homologous protein (CHOP), and p NF kB p65 expression and elevation of interleukin (IL) 6 and tumor necrosis factor (TNF) α levels in the hippocampus. CASP3 drug amphetamine 31228610 These effects preceded the activation of cleaved caspase 3 in dopamine cell bodies, as well as decreases in tyrosine hydroxylase (TH) immunoreactivity in the substantia nigra and dopamine transporter (DAT) immunoreactivity in the striatum measured at 7 days after Meth. CASP3 drug amphetamine 31228610 Intervention with a selective COX 2 inhibitor during EtOH drinking prevented the changes in microglia, and attenuated the increase in cleaved caspase 3, and decreases in TH and DAT after Meth administration. CASP3 drug alcohol 31105269 Alcohol increased IL 17A production and pro apoptotic signaling evidenced by Bax, Bim, caspase 3, and caspase 8 increases via endoplasmic reticulum (ER) stress indicated by C/EBP homologous protein (CHOP) upregulation; this was prevented by the ER stress inhibitor, 4 PBA, in isolated crypts in vitro and in vivo. CASP3 drug alcohol 31068789 OEA restored ethanol/THC related decreases in both short term spatial memory (spontaneous alternation by Y maze) and circulating levels of BDNF, reduced cell proliferation (Mki67 and IdU+ cells) and maturation (Dcx, Calb1), and improved cell survival (Casp3 and BrdU+ cells) in the dorsal hippocampus. CASP3 drug cannabinoid 31068789 OEA restored ethanol/THC related decreases in both short term spatial memory (spontaneous alternation by Y maze) and circulating levels of BDNF, reduced cell proliferation (Mki67 and IdU+ cells) and maturation (Dcx, Calb1), and improved cell survival (Casp3 and BrdU+ cells) in the dorsal hippocampus. CASP3 drug nicotine 30504847 Using western blot, we confirmed downregulation of SIRT1 and increased cleaved caspase 3 expression in the brains of nicotine exposed female rats and no change in expression levels in the other groups. CASP3 drug amphetamine 30456731 Seven days after METH injection, the brains were removed for biochemical assessments, glial fibrillary acidic protein (GFAP), and caspase 3 immunohistochemistry staining. CASP3 drug amphetamine 30456731 Moreover, H2S could significantly decrease caspase 3 and GFAP positive cells in the CA1 region of the hippocampus (P < 0.01) compared to the METH group. CASP3 drug nicotine 30358437 Nicotine also caused a dose dependent increase in epithelial cell death and an increase in caspase 3/7 activities. CASP3 drug amphetamine 30259275 Seven days after METH injection, the rats' brains were removed for biochemical assessment using the ELISA technique, and immunohistochemistry staining was used for caspase 3 and glial fibrillary acidic protein (GFAP) detection. CASP3 drug nicotine 30217256 It is worthy to note that nicotine toxicity induced significant increments in the protein expression levels of nuclear factor kappa B as well as caspase 3. CASP3 addiction intoxication 30069273 Another biological evidence on binge drinking effect include inflammatory response, oxidative stress, formation of toxic ceramides, activation of caspase 3, and secretion of corticoliberin. CASP3 drug nicotine 29906478 Increased oxidative stress by tramadol and/or nicotine sequentially augmented nuclear factor kappa B and the proinflammatory cytokine tumor necrosis factor α with the induction of apoptosis evident by the increased caspase 3 immunoreactivity. CASP3 drug opioid 29906478 Increased oxidative stress by tramadol and/or nicotine sequentially augmented nuclear factor kappa B and the proinflammatory cytokine tumor necrosis factor α with the induction of apoptosis evident by the increased caspase 3 immunoreactivity. CASP3 drug alcohol 29404485 Furthermore, cell death rates were elevated when primary hepatocytes or human hepatoma cells were exposed to EVs from alcohol exposed rodents and patients with alcoholism, demonstrating that EVs from alcohol exposed rats and patients with alcoholism are functional and can promote cell death by activating the apoptosis signaling pathway, including phospho c Jun N terminal kinase, proapoptotic Bax, and activated caspase 3. CASP3 drug alcohol 29205963 The α syn and caspase 3 were detected by immunohistochemical staining and imaging analysis at 1 h, 3 h, 6 h and 12 h after acute alcoholism. CASP3 drug alcohol 29205963 The number of α syn positive cell and average optical density in brain cortex of acute alcoholism rat increased significantly and peaked at 6 hour with a following slight decrease at 12 h, but still higher than the groups at 1 h and 3 h. Within 12 hours after poisoning, the number of caspase 3 positive cell and average optical density in brain cortex of rats gradually increased. CASP3 drug alcohol 28784931 Alcohol administration inhibited this activation of lin c kit+ Sca 1+ cells. CASP3 drug alcohol 28784931 Alcohol disrupted lipopolysaccharide (LPS) TLR4 ERK1/2 cyclin D1 signaling and inhibited upregulation of Sca 1 and C/EBPβ expression by lineage negative marrow cells in response to bacteremia. CASP3 drug nicotine 28691127 Western blotting showed marked significant elevation in caspase 3 activities against nicotine. CASP3 drug amphetamine 28552341 Meth/gp120 activated caspase 3 and increased caspase 3/7 activity in microglia and inhibition of caspase 3 by its specific inhibitor significantly decreased microglial production of TNF α and iNOS and attenuated microglia associated neurotoxic activity. CASP3 drug amphetamine 28552341 Moreover, blockage of KV1.3 by specific blockers attenuated Meth/gp120 enhancement of caspase 3/7 activity. CASP3 drug amphetamine 28552341 Taking together, these results suggest an involvement of microglial KV1.3 in the mediation of Meth/gp120 co morbid effect on microglial neurotoxic activity via caspase 3 signaling. CASP3 drug alcohol 27826748 Biochemical analyses revealed that ethanol administration induced an increase in the production of reactive oxygen species and the activity of caspase 3 in PACAP KO mice in an age independent manner. CASP3 drug alcohol 27665770 Acetaminophen and ethanol, which are also hepatotoxicants but do not induce idiosyncratic DILI, did not affect the OCR or caspase 3/7 activity. CASP3 drug alcohol 27628528 Moreover, bilateral microinjections of ethanol did not change the expression of either pro apoptotic (caspase 3 and Bax) or anti apoptotic (Bcl 2) proteins, suggesting that the dose was safe and validating the method used in the current study. CASP3 drug alcohol 27565756 Additionally, we also observed increased activated caspase3 staining in hippocampal cells 24 h after ethanol withdrawal. CASP3 addiction withdrawal 27565756 Additionally, we also observed increased activated caspase3 staining in hippocampal cells 24 h after ethanol withdrawal. CASP3 drug opioid 27544013 In order to elucidate the influences of CCK 8 on expressions of apoptosis related genes, Bax, Bcl 2 and Caspase 3, of prefrontal cortex neurons in morphine relapse rats, an effective, successful morphine relapse rat model using the conditioned place preference (CPP) under CCK 8 (0.01, 0.1 and 1.0μg, i.c.v) intervention was established.

CASP3 addiction reward 27544013 In order to elucidate the influences of CCK 8 on expressions of apoptosis related genes, Bax, Bcl 2 and Caspase 3, of prefrontal cortex neurons in morphine relapse rats, an effective, successful morphine relapse rat model using the conditioned place preference (CPP) under CCK 8 (0.01, 0.1 and 1.0μg, i.c.v) intervention was established. CASP3 drug opioid 27544013 The results showed that the expression of Bcl 2 was very weak and those of Bax and Caspase 3 were hardly seen in group normal saline; the expressions of Bax and Caspase 3 were strong and that of Bcl 2 was weak in group morphine and compared to group normal saline, there were significant differences (P<0.05); the expressions of Bax, Caspase 3 and the ratios of Bax/Bcl 2 have a gradually decreased trend in the sequence of group 0.01μg, group 0.1μg and group 1.0μg, but the expression of Bcl 2 has an opposite trend in the same sequence, and compared to group morphine, there were significant differences (P<0.05) excluding group 0.01μg. CASP3 drug opioid 27544013 So we draw a conclusion that CCK 8 (0.1 and 1.0μg, i.c.v) could protect neurons of prefrontal cortex through up regulating the expression of Bcl 2, down regulating those of Bax and Caspase 3 and reducing Bax/Bcl 2 ratio in the model of morphine relapse rats. CASP3 addiction relapse 27544013 So we draw a conclusion that CCK 8 (0.1 and 1.0μg, i.c.v) could protect neurons of prefrontal cortex through up regulating the expression of Bcl 2, down regulating those of Bax and Caspase 3 and reducing Bax/Bcl 2 ratio in the model of morphine relapse rats. CASP3 drug alcohol 27527870 Ethanol caused both apoptotic and necrotic cell death which was demonstrated by the increase in active caspase 3, caspase 8, cleaved PARP, cleaved CK 18 and the secretion of high mobility group protein B1 (HMGB1). CASP3 drug nicotine 26909550 This effect correlated with the induction of Bcl 2, Bax, Survivin and Caspase 3 by nicotine in gastric cell lines. CASP3 drug alcohol 26857094 OEA also prevented ethanol induced lipid peroxidation, caspase 8 and pro apoptotic caspase 3 activation in frontal cortex. CASP3 drug alcohol 26805422 Binge ethanol treated rats demonstrated a significant increase in KLF11, both MAO isoforms, protein oxidation and caspase 3, as well as a reduction in BDNF expression in the frontal cortex compared to control rats. CASP3 addiction intoxication 26805422 Binge ethanol treated rats demonstrated a significant increase in KLF11, both MAO isoforms, protein oxidation and caspase 3, as well as a reduction in BDNF expression in the frontal cortex compared to control rats. CASP3 drug cocaine 26790673 Levels of MDA and TNFα in PFC, and levels of MDA, SOD, GSH, IL 6, IL 1β, TNFα, caspase 3 and BAX in HP, but not SIRT1 expression in both regions were significantly changed during cocaine withdrawal period. CASP3 addiction withdrawal 26790673 Levels of MDA and TNFα in PFC, and levels of MDA, SOD, GSH, IL 6, IL 1β, TNFα, caspase 3 and BAX in HP, but not SIRT1 expression in both regions were significantly changed during cocaine withdrawal period. CASP3 drug psychedelics 25937004 24h following washout of the specific drug, a significant elevation of the pro apoptotic marker BAX, as well as activated Caspase 3 positive neurons, could be detected in cultures exposed to 100μM MK801 and 25μM S(+) ketamine. CASP3 drug opioid 25846801 Various regimens of morphine reduced TWI, cortisol levels, Bax activity, caspase 3, caspase 9, TNF α, and IL 1β and lipid peroxidation. CASP3 drug opioid 25712644 The results showed that morphine significantly increased lipid peroxidation, mitochondrial GSH level, concentration of Bax; caspase 3 and caspase 9 activities while decreasing Bcl 2 concentration. CASP3 drug amphetamine 25631491 In addition, blocking caspase 11 expression inhibited METH induced activation of caspase 3 and PARP in vitro and in vivo, suggesting that caspase 11/caspase 3 signal pathway is involved in METH induced neurotoxicity. CASP3 drug opioid 25597171 Group II also exhibited a significantly reduced epididymal perm count (P < 0.05) and remarkably upregulated expressions of Bax and Caspase 3 in comparison with group I. Morphine might increase testicular cell apoptosis and reduce sperm concentration by upregulating the expressions of Bax and Caspase 3 in the rat model of morphine tolerance. CASP3 drug alcohol 25556946 In adolescent animals, alcohol decreased the expression of genes involved in the repair and protection of oxidative DNA damage such as atr, gpx7, or nudt15 and increased the expression of proapoptotic genes such as casp3. CASP3 drug amphetamine 25260424 Proliferation of progenitors via Ki 67 labeling and apoptosis via activated caspase 3 labeling were studied in rats that intravenously self administered methamphetamine in a limited access (1h/day: short access (ShA)) or extended access (6h/day: long access (LgA)) paradigm over 4, 13, 22 or 42 sessions, and in rats that experienced 22 sessions and were withdrawn from self administration for a period of 4weeks. CASP3 drug opioid 24959978 In this study, we investigated the effects of morphine induced conditioned place preference (CPP) in the presence and absence of stress on the changes of apoptotic factors (Bax/Bcl 2 ratio, caspase 3 activation and PARP degradation) in the MCL system. CASP3 addiction reward 24959978 In this study, we investigated the effects of morphine induced conditioned place preference (CPP) in the presence and absence of stress on the changes of apoptotic factors (Bax/Bcl 2 ratio, caspase 3 activation and PARP degradation) in the MCL system. CASP3 drug opioid 24959978 In the morphine treated animals, AS and SS increased apoptotic factors remarkably (except for the Bax/Bcl 2 ratio after AS and SS in the Str and caspase 3 activation after AS in the NAc) and also decreased conditioning scores. CASP3 drug alcohol 24625836 Several fold increases for cytochrome P450 2E1, caspase 8 and caspase 3 found in the lungs of ethanol fed mice as compared to pair fed controls suggest role of oxidative stress in ethanol induced lung injury. CASP3 drug alcohol 24507877 The alcohol injections on PD 7 produced average peak blood alcohol concentrations of 472 mg/dL and evoked typical patterns of activated caspase 3 positive neurons in the cortex, hippocampal formation, and striatum 6 h after the last injection. CASP3 drug cocaine 24409127 Additionally, we measured cell apoptosis (as monitored by the expression of cleaved caspase 3) and glial activation [by analyzing the expression of glial fibrillary acidic protein (GFAP) and Iba 1] in the striatum and hippocampus during acute and repeated (4 days) cocaine administration (20 mg/kg). CASP3 drug cannabinoid 24409127 Both acute and repeated cocaine exposure increased the number of cleaved caspase 3 , GFAP and Iba1 ir cells in the hippocampus, and this effect was counteracted by AM630 or Rimonabant, which increased the number of BrdU , GFAP , and Iba1 ir cells in the hippocampus. CASP3 drug cocaine 24409127 Both acute and repeated cocaine exposure increased the number of cleaved caspase 3 , GFAP and Iba1 ir cells in the hippocampus, and this effect was counteracted by AM630 or Rimonabant, which increased the number of BrdU , GFAP , and Iba1 ir cells in the hippocampus. CASP3 drug opioid 24096212 In the NAc, morphine significantly increased the Bax/Bcl 2 ratio, caspase3 and PARP in the lowest dose (0.5mg/kg) but in the PFC considerable increase was seen in dose of 5mg/kg. CASP3 drug opioid 23936592 This study aimed to investigate neuronal apoptosis and expression of apoptosis related proteins (Fas, Caspase 3 and Bcl 2) in the brain of rates with morphine addiction. CASP3 addiction addiction 23936592 This study aimed to investigate neuronal apoptosis and expression of apoptosis related proteins (Fas, Caspase 3 and Bcl 2) in the brain of rates with morphine addiction. CASP3 addiction addiction 23936592 When compared with the control group, the proportion of apoptotic neurons increased significantly in the addiction group and the abstinence group (P<0.01), accompanied by significantly increased expressions of Fas and Caspase 3 (P<0.01) and markedly decreased Bcl 2 expression (P<0.01) in the hippocampuse. CASP3 drug opioid 23936592 Long term use of morphine can induce neuronal apoptosis in the brain by increasing the expressions of pro apoptotic Fas and Caspase 3 and decreasing the anti apoptotic Bcl 2 expression, which might be one of mechanisms underlying the opiate induced neuronal damage. CASP3 drug alcohol 23567812 Quantitative analyses of immunoreactivity revealed a significant reduction in measures of neurogenesis, progenitor proliferation, as indexed by doublecortin (DCX), Ki67, and increased markers of cell death as indexed by cleaved caspase 3, and Fluoro Jade at 72 days, and decreases in DCX, and increases in cleaved caspase 3 at 114 days in the ethanol vapor exposed rats. CASP3 drug alcohol 23396011 In addition, it appears that increased dimethylation of H3K9 makes it susceptible to proteolytic degradation by caspase 3 in conditions in which ethanol induces neurodegeneration. CASP3 drug opioid 23319379 Bax and cleaved caspase 3 were positive only in the heroin subjects. CASP3 addiction reward 27385959 In this study, the effects of acute and subchronic stress on the changes in apoptotic factors (Bax/Bcl 2 ratio, caspase 3 activation and PARP degradation) in the HYP and HIP during conditioned place preference (CPP) paradigm were evaluated. CASP3 drug opioid 27385959 Caspase 3 and PARP increased during AS and SS in saline or morphine treated animals. CASP3 drug opioid 27385959 For example, caspase 3 increased during AS and SS in morphine treated animals by 2.4 folds and PARP (89 KDa) increased by 3.1 and 3.5 folds, respectively. CASP3 drug alcohol 23102656 Collaborating on studies of subchronic daily intoxication in juvenile and adult rats, we examined whether the repetitive ethanol treatments at these two life stages altered levels of key neuroinflammation associated proteins aquaporin 4 (AQP4), certain phospholipase A2 (PLA2) enzymes, PARP 1 and caspase 3 in hippocampus (HC) and entorhinal cortex (EC).

CASP3 drug alcohol 23102656 Furthermore, the robust PARP 1 elevations accompanied by negligible caspase 3 activation indicate that repetitive ethanol intoxication may be potentiating non apoptotic neurodegenerative processes such as parthanatos. CASP3 addiction intoxication 23102656 Furthermore, the robust PARP 1 elevations accompanied by negligible caspase 3 activation indicate that repetitive ethanol intoxication may be potentiating non apoptotic neurodegenerative processes such as parthanatos. CASP3 addiction intoxication 22404759 Acute apoptotic Pcell death 10 hours after a moderate dose binge EtOH exposure from postnatal days (PDs) 0 to 10 was assessed using active caspase 3 immunolabeling. CASP3 drug alcohol 22238460 In this study, we investigated the role of Sca 1 in promoting ERK dependent myeloid lineage proliferation and the effects of alcohol on this process. CASP3 drug opioid 22210043 Protein expression of cleaved caspase 3 and Bax decreased, whereas Bcl 2 protein levels in hippocampus increased with exogenous H(2)S. Exogenous H(2)S alleviated heroin induced rat hippocampal damage through antioxidant and antiapoptosis effects. CASP3 addiction dependence 23983323 These effects showed a time dependence over 48 hours of incubation, with high doses of SFE extracts eliminating viable cells by necrosis, depleting ATP levels and decreasing caspase 3/ 7 activity (p< 0.001). CASP3 drug cocaine 21925237 Chronic exposure to cocaine in rats, including withdrawal for 3 days, did not alter Fas FADD receptor complex, cytochrome c, caspase 3/fragments, AIF, PARP 1 cleavage, and associated signaling in the cerebral cortex. CASP3 addiction withdrawal 21925237 Chronic exposure to cocaine in rats, including withdrawal for 3 days, did not alter Fas FADD receptor complex, cytochrome c, caspase 3/fragments, AIF, PARP 1 cleavage, and associated signaling in the cerebral cortex. CASP3 drug alcohol 21803053 After 4h, a single dose of ethanol induced upregulation of Bax, release of mitochondrial cytochrome c into the cytosol, activation of caspase 3 and cleavage of poly (ADP ribose) polymerase (PARP 1), all of which promote apoptosis. CASP3 drug alcohol 21664448 These structures showed activation of caspase 3 and 9 but not of caspase 8 suggesting that alcohol induced apoptosis could occur by the intrinsic pathway. CASP3 drug opioid 21483469 Enhanced toxicity by Tat and morphine was accompanied by increased numbers of TUNEL positive apoptotic neurons, elevated caspase 3 levels and decreased ratio of anti and pro apoptotic proteins, Bcl2/Bax. CASP3 drug alcohol 20870739 Cultured rat PSCs were exposed to 10 mM ethanol 6 1 mg/ml LPS for 48 or 72 h and apoptosis was assessed (Annexin V, caspase 3 and terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL)). CASP3 drug opioid 20711699 Although minocycline did not change the level of caspase 3 at the doses used with morphine but the minocycline treated rats showed a significantly lower increase in caspase 3 activity than did in the control. CASP3 drug opioid 20600172 In this study, we show that morphine induces microglia apoptosis and caspase 3 activation in an opioid receptor dependent manner. CASP3 drug opioid 20600172 In addition, inhibition of p38 MAPK by its specific inhibitor SB203580 significantly inhibited morphine induced apoptosis and caspase 3 activation. CASP3 drug psychedelics 20526188 After intrathecal injection of ketamine at P3, 7, or 21, spinal cords were examined for apoptosis (Fluoro Jade C and activated caspase 3), histopathologic change, and glial responses (ionized calcium binding adapter molecule 1 and glial fibrillary acid protein). CASP3 drug alcohol 20090911 Myocardium from ethanol treated mice displayed enhanced Bax, Caspase 3 and decreased Bcl 2 expression, the effect of which with the exception of Caspase 3 was augmented by ADH. CASP3 drug amphetamine 19663261 Furthermore, high concentration of METH, but not MPH, reduced MAP2a/b positive cells and activated the immunoreactivity of the cleaved caspase 3 in primary cultured limbic neurons, whereas MPH had no such effect. CASP3 drug psychedelics 19580862 Although a few caspase 3 and Fluoro Jade C positive neuronal profiles were observed in some additional brain areas including the hippocampus, thalamus, striatum and amygdala, no significant differences were detected between ketamine treated and control monkeys in these areas after 3, 9 or 24h of exposure.

CASP3 drug alcohol 19155505 Alcohol also suppressed the plasma TNF alpha response to bacteremia and inhibited TNF alpha induced phenotypic inversion of lin( )c kit(+)Sca 1(+)Sca 1( ) cells in vitro. CASP3 drug alcohol 19073235 The investigation of downstream signaling pathways involving NAP neuroprotection revealed that this peptide significantly prevented alcohol induced increase in the concentrations of caspase 3 in E13 fetal brains.

CASP3 drug opioid 18676827 Methadone inhibited proliferation in leukemia cells and induced cell death through apoptosis induction and activated apoptosis pathways through the activation of caspase 9 and caspase 3, down regulation of Bcl x(L) and X chromosome linked inhibitor of apoptosis, and cleavage of poly(ADP ribose) polymerase. CASP3 addiction withdrawal 18486243 This was not accompanied by enhanced neurotoxicity or reactive gliosis as demonstrated by the immunohistological analysis using the apoptotic marker activated Caspase 3 and GFAP (glial fibrillary acidic protein; a marker for astrocytes) following both short and long term withdrawal periods. CASP3 drug psychedelics 17920787 Stereologic quantification of silver stained nuclear and linear profiles as well as activated caspase 3 labeling was used to address: (1) whether or not ketamine increases excitotoxic and apoptotic cell death in hippocampal CA3 and (2) whether or not ketamine induced cell death varies by genetic background. CASP3 drug psychedelics 17920787 Neither silver staining nor activated caspase 3 labeling varied by strain, nor was there an interaction between ketamine induced cell death and strain. CASP3 drug alcohol 17706724 An increase in the caspase 3 activity in PC12 cells deprived of serum was observed that was further increased by ethanol exposure. CASP3 drug amphetamine 17647000 Using methods employed and confirmed in traumatic brain injury (TBI) studies, rat brain tissues were examined, 24 and 48 h after Meth and MDMA exposure, for the activation of calpain 1 and caspase 3, and their subsequent alphaII spectrin cleavage breakdown products (SBDPs), SBDP145, and SBDP120, respectively.

CASP3 drug psychedelics 17426105 Ketamine (24 h infusion) produced a significant increase in the number of caspase 3 , Fluoro Jade C and silver stain positive cells in the cortex of gestational and PND 5 animals but not in PND 35 animals. CASP3 drug opioid 17250679 Ionotropic glutamate receptors, opioid receptors and oxidative stress were not involved in caspase 3 activation. CASP3 drug opioid 17250679 Pure heroin hydrochloride similarly decreased metabolic viability but only slightly activated caspase 3. CASP3 drug amphetamine 17161385 Moreover, there was METH induced expression of activated caspase 3 in TH positive cells.

CASP3 drug amphetamine 16622715 In this study, we examined the suitability of the immunohistochemical detection of tyrosine hydroxylase (TH), dopamine transporter (DAT), and vesicular monoamine transporter 2 (VMAT2) levels, and caspase 3 activation in the striatum to diagnose METH abuse. CASP3 drug amphetamine 16622715 On the other hand, we observed little caspase 3 activation, indicative of apoptosis, in the striatal neurons of chronic METH users. CASP3 addiction dependence 16555300 Results show that Ca(2+) activation of the transcription factor cAMP responsive element binding protein (CREB) and Ca(2+) induced alterations in the level of the apoptotic enzyme caspase 3 show both dose and age dependence in the early developing Purkinje neurons. CASP3 drug alcohol 16555300 Exposure to ethanol altered Ca(2+) activation of pCREB in an age dependent manner but did not alter Ca(2+) regulation of caspase 3 or calbindin levels. CASP3 drug opioid 16496378 After a single dose of morphine, no apoptotic cells were detected by TUNEL or active caspase 3 immunocytochemistry. CASP3 drug alcohol 16317704 In lean mice, these moderate ethanol doses did not increase plasma TNF alpha and hepatic caspase 3 activity, but triggered some apoptotic hepatocytes. CASP3 addiction intoxication 15654300 Vitamin E also failed to protect against increases in caspase 3 active subunit expression induced by acute binge EtOH exposure on PD 4. CASP3 drug opioid 15628595 Indices of oxidative stress, nitric oxide (NO) metabolism as well as the activity of caspase 3, an important enzyme of apoptotic cell death, were measured during the morphine withdrawal syndrome in liver and thymus of rats. CASP3 addiction withdrawal 15628595 Indices of oxidative stress, nitric oxide (NO) metabolism as well as the activity of caspase 3, an important enzyme of apoptotic cell death, were measured during the morphine withdrawal syndrome in liver and thymus of rats. CASP3 drug alcohol 15550790 Activity of caspase 3 was higher in ethanol treated groups (P < 0.05). CASP3 drug opioid 15217373 Moreover, the increased cell death is mediated by mu opioid receptors and accompanied by the activation of caspase 3.

CASP3 drug cocaine 14741756 c fos and cleaved caspase 3 expression after perinatal exposure to ethanol, cocaine, or the combination of both drugs. CASP3 drug alcohol 14741756 Increased cleaved caspase 3 expression was observed at the 24 h time point for both ethanol and cocaine exposed brains, most notably in the septum, retrosplenial cortex, and the hippocampus. CASP3 drug cocaine 14741756 Increased cleaved caspase 3 expression was observed at the 24 h time point for both ethanol and cocaine exposed brains, most notably in the septum, retrosplenial cortex, and the hippocampus. CASP3 drug alcohol 14741756 Concurrent ethanol and cocaine exposure did not elevate cleaved caspase 3 expression beyond that of either drug alone. CASP3 drug cocaine 14741756 Concurrent ethanol and cocaine exposure did not elevate cleaved caspase 3 expression beyond that of either drug alone. CASP3 drug alcohol 14741756 These results indicate that both prenatal cocaine and prenatal ethanol exposure increase Fos and cleaved caspase 3 expression in the developing brain in a time and region dependent manner, but that the combination of low dose, chronic ethanol, and binge cocaine does not cause greater apoptosis. CASP3 drug cocaine 14741756 These results indicate that both prenatal cocaine and prenatal ethanol exposure increase Fos and cleaved caspase 3 expression in the developing brain in a time and region dependent manner, but that the combination of low dose, chronic ethanol, and binge cocaine does not cause greater apoptosis. CASP3 addiction intoxication 14741756 These results indicate that both prenatal cocaine and prenatal ethanol exposure increase Fos and cleaved caspase 3 expression in the developing brain in a time and region dependent manner, but that the combination of low dose, chronic ethanol, and binge cocaine does not cause greater apoptosis. CASP3 drug alcohol 14724834 Ethanol binge increased caspase 3 and caspase 8 activity, the expression of Fas ligand, and terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate nick end labeling in fa/fa rats. CASP3 addiction intoxication 14724834 Ethanol binge increased caspase 3 and caspase 8 activity, the expression of Fas ligand, and terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate nick end labeling in fa/fa rats. CASP3 drug alcohol 14615011 Results also showed that ethanol withdrawn rats had more caspase 3 positive cells than observed for the dextrin diet fed group in a manner reversed by E(2) and exacerbated by bicuculline. CASP3 drug alcohol 14615010 These findings support the suggestion that E(2) protects against cerebellar neuronal damage in ethanol withdrawn rats by inhibition of DNA fragmentation and caspase 3 activation, and that reduced PKC activity may be involved in the protection. CASP3 drug alcohol 14502238 The cell death process occurs over a 6 16 h period following ethanol administration, is accompanied by a robust display of caspase 3 enzyme activation, and meets ultrastructural criteria for apoptosis. CASP3 drug alcohol 14502238 We also found that ethanol triggers robust caspase 3 activation and apoptotic neurodegeneration in C57BL/6 wildtype mice, but induces neither phenomenon in homozygous Bax deficient mice. CASP3 drug alcohol 14502238 Therefore, it appears that ethanol induced neuroapoptosis is an intrinsic pathway mediated phenomenon involving Bax induced disruption of mitochondrial membranes and cytochrome c release as early events leading to caspase 3 activation. CASP3 drug cocaine 12821377 Blockade of D1 dopaminergic transmission alleviates c fos induction and cleaved caspase 3 expression in the brains of rat pups exposed to prenatal cocaine or perinatal asphyxia. CASP3 drug cocaine 12821377 We used immediate early gene and cleaved caspase 3 expression patterns to monitor fetal brain regions affected by intrauterine hypoxia and prenatal cocaine and pretreatment with the D1 dopamine receptor antagonist SCH 23390 to determine how much of the induction observed was due to dopamine. CASP3 drug cocaine 12821377 Cells immunoreactive for cleaved caspase 3 expression were more numerous after perinatal asphyxia than after prenatal cocaine exposure in most brain regions 24 h after C section.

CASP3 drug nicotine 11682702 This study examined the effects and the mechanisms of action of nicotine on dexamethasone (DEX) induced apoptosis in murine immune cells by examining the expression of levels of the 17 kDa active caspase 3, a marker of apoptosis. CASP3 drug nicotine 11682702 The data showed that nicotine significantly blocked the formation of the DEX induced 17 kDa caspase 3 subunit expression. CASP3 drug nicotine 11682702 Addition of d tubocurarine chloride (dTC), a general nicotinic receptor antagonist, inhibited nicotine downregulation of the DEX induced active caspase 3 expression, providing evidence that this action of nicotine was receptor mediated. CASP3 drug alcohol 11438480 Ethanol induced apoptosis in mouse liver: Fas and cytochrome c mediated caspase 3 activation pathway. CASP3 drug alcohol 11438480 This study was undertaken to examine specifically the involvement of the upstream signals, Fas and cytochrome c, in alcohol induced caspase 3 activation and apoptosis in the liver. CASP3 drug alcohol 11438480 The results thus demonstrate that Fas/Fas ligand system mediated caspase 3 activation plays a central role in the ethanol induced hepatic apoptosis. CASP3 drug alcohol 10607886 Inclusion of ethanol during the serum deprivation augmented Ac DEVD amc cleavage without further increasing the amount of active caspase 3. CASP3 drug alcohol 10607886 The ability of ethanol to promote apoptosis involves an increase in caspase activity, but this does not entail an increase in the proteolytic activation of caspase 3. CASP3 addiction withdrawal 10602513 The activity of caspase 3 detected in K562 Tat cells after serum withdrawal paralleled with the mitochondria permeability transition. CASP3 drug opioid 10534122 In addition, morphine treated Jurkat cells showed activation of caspase 3.

NGF drug cocaine 16179556 In the present study, we evaluated the effect of increasing doses of cocaine on the expression of immediate early genes (IEGs), c fos and c jun, and closely related transcription factors, SP 1 and NF kbeta, at 24 h after the exposure to cocaine (50, 100, 200, 500, 1000, 2500 microM) in NGF differentiated PC12 cells. NGF addiction sensitization 15836976 Anti NGF therapy profoundly reduces bone cancer pain and the accompanying increase in markers of peripheral and central sensitization. NGF drug opioid 15836976 As nerve growth factor (NGF) has been shown to modulate inflammatory and neuropathic pain states, we focused on a novel NGF sequestering antibody and demonstrated that two administrations of this therapy in a mouse model of bone cancer pain produces a profound reduction in both ongoing and movement evoked bone cancer pain related behaviors that was greater than that achieved with acute administration of 10 or 30 mg/kg of morphine.

NGF addiction sensitization 15836976 Mechanistically, the great majority of sensory fibers that innervate the bone are CGRP/TrkA expressing fibers, and if the sensitization and activation of these fibers is blocked by anti NGF therapy there would not be another population of nociceptors, such as the non peptidergic IB4/RET IR nerve fibers, to take their place in signaling nociceptive events. NGF drug alcohol 15520530 The effects of nerve growth factor upon the neuropeptide content of the suprachiasmatic nucleus of rats withdrawn from ethanol are mediated by the nucleus basalis magnocellularis. NGF drug alcohol 15520530 It has been previously shown that withdrawal from alcohol decreases the synthesis and expression of vasopressin (VP) and vasoactive intestinal polypeptide (VIP) in the suprachiasmatic nucleus (SCN), and that the infusion of NGF over 1 month completely restores these changes. NGF addiction withdrawal 15520530 It has been previously shown that withdrawal from alcohol decreases the synthesis and expression of vasopressin (VP) and vasoactive intestinal polypeptide (VIP) in the suprachiasmatic nucleus (SCN), and that the infusion of NGF over 1 month completely restores these changes. NGF drug alcohol 15520530 For this purpose we destroyed, with quinolinic acid, the NBM of rats withdrawn from ethanol and later infused them with NGF over a period of 13 days. NGF drug alcohol 15296847 The parietal cortex was susceptible to ethanol exposure, NGF and BDNF content increased, and NT 3 content fell, whereas no changes were detectable in the entorhinal cortex. NGF drug alcohol 15296847 Neurotrophin content in the two segments of the basal forebrain was affected; NGF and NT 3 content in the basal forebrain was reduced and NGF and BDNF content in the septal nuclei was increased by ethanol exposure. NGF drug alcohol 15246696 Ethanol exposure during this vulnerable window induces rapid apoptotic Purkinje cell death that is hypothesized to result from ethanol inhibition in brain derived nerve growth factor (BDNF) TrkB neurotrophic signaling that results in loss of apoptotic suppression. NGF drug nicotine 15066159 Additionally, neonatal quinpirole produced a significant decrease in hippocampal NGF content compared to controls, however, nicotine failed to alleviate this decrease in NGF. NGF drug benzodiazepine 15009662 In wild type animals, diazepam reduced the expression levels of the alpha subunit of the calcium/calmodulin dependent protein kinase II, as well as brain derived neurotrophic factor, MAP kinase phosphatase, transcription factor GIF, c fos and nerve growth factor induced gene A. NGF drug cocaine 14973246 A single intra VTA infusion of BDNF, but not NGF, induced long lasting enhancement of cocaine seeking for up to 30 d, an effect reversed by U0126. NGF addiction relapse 14973246 A single intra VTA infusion of BDNF, but not NGF, induced long lasting enhancement of cocaine seeking for up to 30 d, an effect reversed by U0126. NGF drug cannabinoid 14639155 A novel neuroimmune mechanism in cannabinoid mediated attenuation of nerve growth factor induced hyperalgesia. NGF drug cannabinoid 14639155 The effects of administration of the cannabinoid anandamide and the cannabimimetic palmitoylethanolamide on an NGF induced hyperalgesia and neutrophil accumulation were examined in this study. NGF addiction withdrawal 14639155 Baseline hind limb withdrawal latencies to a noxious heat stimulus were recorded before intraplantar administration of NGF (1 microg in 0.05 ml) to the hind paw of 75 male Wistar rats. NGF drug cannabinoid 14639155 Anandamide or palmitoylethanolamide (a substance that has cannabinoid like actions but little affinity for cannabinoid receptors) at doses of 10 and 25 mg/kg were given (intraperitoneally) immediately after NGF. NGF drug cannabinoid 14639155 NGF induced a thermal hyperalgesia that was attenuated by anandamide and palmitoylethanolamide. NGF drug nicotine 14500754 Differential regulation of nicotinic acetylcholine receptors in PC12 cells by nicotine and nerve growth factor. NGF drug nicotine 14500754 Two subtypes of receptors labeled by [3H]epibatidine were found: one that was increased about 4 fold in cells grown for 2 to 4 days in the presence of nicotine and one that was increased 5 fold in cells grown for 2 to 4 days in the presence of nerve growth factor (NGF). NGF drug nicotine 14500754 Two subtypes of receptors labeled by [3H]epibatidine were found: one that was increased about 4 fold in cells grown for 2 to 4 days in the presence of nicotine and one that was increased 5 fold in cells grown for 2 to 4 days in the presence of nerve growth factor (NGF). NGF drug nicotine 14500754 The pharmacology of the binding sites in the nicotine and NGF treated cells was compared with the pharmacology of defined alpha3beta2 and alpha3beta4 nicotinic acetylcholine receptor (nAChR) subtypes heterologously expressed in human embryonic kidney 293 cells. NGF drug nicotine 14500754 Nicotine treatment predominantly increased a receptor with characteristics of an alpha3beta2 subtype, whereas the NGF treatment exclusively increased a receptor with characteristics of an alpha3beta4 subtype. NGF drug nicotine 14500754 Receptor function measured with the [3H]norepinephrine release assay was measurable in both nicotine treated and NGF treated cells; however, cytisine stimulated [3H]norepinephrine release indicated that nicotine treatment increased an nAChR containing beta2 subunits, whereas NGF increased a receptor containing beta4 subunits. NGF drug nicotine 14500754 NGF treatment increased mRNA only for beta4 subunits in these cells, whereas nicotine treatment did not affect mRNA for any of the subunits measured. NGF drug nicotine 14500754 After withdrawal of the treatments, the receptors increased by nicotine were much less stable than those increased by NGF. NGF addiction withdrawal 14500754 After withdrawal of the treatments, the receptors increased by nicotine were much less stable than those increased by NGF. NGF drug nicotine 12970390 Nicotine (1 1000 muM) produced a concentration dependent increase in cell viability in differentiated PC 12 cells that underwent nerve growth factor withdrawal for 24 h.

NGF drug alcohol 12914967 NGF and NT 3 exert differential effects on the expression of neuropeptides in the suprachiasmatic nucleus of rats withdrawn from ethanol treatment. NGF drug alcohol 12914967 It was also recently shown that NGF, infused over 1 month, offsets the decreased synthesis and expression of vasopressin (VP) and vasoactive intestinal polypeptide (VIP) in the suprachiasmatic nucleus (SCN) of rats submitted to chronic ethanol treatment and withdrawal. NGF addiction withdrawal 12914967 It was also recently shown that NGF, infused over 1 month, offsets the decreased synthesis and expression of vasopressin (VP) and vasoactive intestinal polypeptide (VIP) in the suprachiasmatic nucleus (SCN) of rats submitted to chronic ethanol treatment and withdrawal. NGF drug alcohol 12831864 Nerve growth factor prevents cell death and induces hypertrophy of basal forebrain cholinergic neurons in rats withdrawn from prolonged ethanol intake. NGF drug alcohol 12831864 Because neurons in these nuclei are vulnerable to ethanol consumption and withdrawal we thought of interest to investigate, in withdrawn rats previously submitted to a prolonged period of ethanol intake, the effects of intraventricular delivery of NGF upon the MS/VDB cholinergic neurons. NGF addiction withdrawal 12831864 Because neurons in these nuclei are vulnerable to ethanol consumption and withdrawal we thought of interest to investigate, in withdrawn rats previously submitted to a prolonged period of ethanol intake, the effects of intraventricular delivery of NGF upon the MS/VDB cholinergic neurons. NGF addiction withdrawal 12831864 NGF treatment prevented the withdrawal associated loss, and induced hypertrophy, of cholinergic neurons. NGF addiction withdrawal 12831864 These findings show that exogenous NGF protects the phenotype and prevents the withdrawal induced degeneration of cholinergic neurons in the MS/VDB. NGF drug alcohol 12763581 Nerve growth factor and chronic ethanol treatment alter calcium homeostasis in developing rat septal neurons. NGF addiction withdrawal 12763581 PCET CET decreased and acute EtOH withdrawal increased overall K(+) stimulated changes in [Ca(2+)](i), but only in +NGF PCET neurons. NGF addiction withdrawal 12763581 NGF reduced overall K(+) stimulated changes in [Ca(2+)](i) in PCET neurons during EtOH withdrawal and during AET with 200 mg % EtOH and increased overall K(+) stimulated changes in [Ca(2+)](i) during AET with 400 and 800 mg % EtOH. NGF drug amphetamine 12638131 Using these criteria, the mRNA for three immediate early genes (IEGs), coding for activity regulated cytoskeletal associated protein (Arc), nerve growth factor induced protein A (NGFI A; early growth response protein 1) and nerve growth factor induced protein B (NGFI B), were upregulated 1 and 3 h after amphetamine as previously described.

NGF drug alcohol 12478399 During the first 4 weeks after the animals were withdrawn from ethanol, they were intraventricularly infused with either NGF or vehicle alone via implanted osmotic minipumps. NGF drug alcohol 12478399 These data provide support to the notion that NGF is capable of ameliorating memory deficits and restoring septohippocampal cholinergic projections following chronic treatment with ethanol. NGF drug amphetamine 12231455 Neither NGF antibody nor DA receptor antagonists blocked AMPH induced neurite outgrowth, demonstrating that AMPH induced neurite outgrowth is not dependent on endogenous NGF release or DA receptors. NGF drug amphetamine 12223225 Differentiation of the cells with nerve growth factor did not alter the amphetamine mediated dopamine release in control cells or the development of enhanced release in amphetamine treated cells. NGF drug cocaine 12117546 Protein levels of protein tyrosine kinase 2 (PYK2), activity regulated cytoskeletal protein (ARC), as well as an antigen related to nerve growth factor I B (NGFI B RA) were shown to be significantly induced after cocaine administration.

NGF addiction withdrawal 11709626 These findings show that NGF can correct the changes induced by chronic ethanol treatment and withdrawal in the gene expression and protein content of the neuropeptides synthesized by suprachiasmatic neurons. NGF drug opioid 10810245 The mechanism of these effects is unknown, but may involve changes in the expression of nerve growth factor, which is reduced by opioid exposure. NGF drug opioid 10727796 Opioid mechanisms, which are likely of dorsal horn origin, do not fall under the direct influence of nerve growth factor mechanisms and therefore the intriguing possibility is raised that opioid mechanisms in the spinal cord are regulated at least in part by substance P related mechanisms.

NGF drug opioid 8545003 Nerve growth factor alone had no effect on tyrosine hydroxylase or glial fibrillary acidic protein levels and did not affect morphine's ability to induce these proteins. NGF drug opioid 3437467 This activity is not due to morphine itself and is not due to an increase in the nerve growth factor as antibodies to nerve growth factor fail to block the response. TLR4 drug opioid 32733481 Toll Like Receptor 4 (TLR4)/Opioid Receptor Pathway Crosstalk and Impact on Opioid Analgesia, Immune Function, and Gastrointestinal Motility. TLR4 drug opioid 32733481 Toll Like Receptor 4 (TLR4)/Opioid Receptor Pathway Crosstalk and Impact on Opioid Analgesia, Immune Function, and Gastrointestinal Motility. TLR4 drug opioid 32733481 This review summarizes the following types of TLR4/opioid receptor pathway crosstalk: (a) Opioid receptor agonists non stereoselectively activate the TLR4 signaling pathway in the central nervous system (CNS), in the absence of lipopolysaccharide (LPS). TLR4 drug opioid 32733481 Opioids bind to TLR4, in a manner parallel to LPS, activating TLR4 signaling, which leads to nuclear factor kappa light chain enhancer of activated B cells (NF κB) expression and the production of the pro inflammatory cytokines tumor necrosis factor (TNF) α, interleukin (IL) 1β, and IL 6. TLR4 drug opioid 32733481 (b) Opioid receptor agonists inhibit the LPS induced TLR4 signaling pathway in peripheral immune cells. TLR4 drug opioid 32733481 It is apparent that TLR4/opioid receptor pathway crosstalk varies dependent on the cell type and activating stimulus. TLR4 drug opioid 32733481 (c) Both the TLR4 and opioid receptor pathways activate the mitogen activated protein kinase (MAPK) pathway. TLR4 drug opioid 32733481 This crosstalk is located downstream of the TLR4 and opioid receptor signaling pathways. TLR4 drug opioid 32733481 (d) Opioid receptor agonists induce the production of high mobility group box 1 (HMGB1), an endogenous TLR4 agonist, supporting intercellular (neuron to glia or glia to neuron) interactions. TLR4 drug opioid 32733481 This review also summarizes the potential effects of TLR4/opioid receptor pathway crosstalk on opioid analgesia, immune function, and gastrointestinal motility. TLR4 drug opioid 32733481 Opioids non stereoselectively activate the TLR4 pathway, and together with the subsequent release of pro inflammatory cytokines such as IL 1 by glia, this TLR4 signaling initiates the central immune signaling response and modifies opioid pharmacodynamics. TLR4 drug opioid 32733481 To explain morphine induced persistent sensitization, a positive feedback loop has been proposed; this involves an initial morphine induced amplified release of IL 1β and a subsequent exacerbated release of DAMPs, which increases the activation of TLR4 and the purinergic receptor P2X7R. TLR4 addiction sensitization 32733481 To explain morphine induced persistent sensitization, a positive feedback loop has been proposed; this involves an initial morphine induced amplified release of IL 1β and a subsequent exacerbated release of DAMPs, which increases the activation of TLR4 and the purinergic receptor P2X7R. TLR4 drug opioid 32733481 The intracellular TLR4/opioid receptor signaling pathway crosstalk induces the formation of the β arrestin 2/TNF receptor associated factor 6 (TRAF6) complex, which contributes to morphine induced inhibition of LPS induced TNF α secretion in mast cells. TLR4 drug opioid 32733481 A possible molecular mechanism is that the TLR4 pathway initially triggers the formation of the β arrestin 2/TRAF6 complex, which is amplified by opioid receptor signaling, suggesting that β arrestin 2 acts as a functional component of the TLR4 pathway. TLR4 drug opioid 32590120 Subsequently the discovery of TLR 4 capacity to bind to opioids on glial cells revealed that they shared the same neuroinflammatory mechanisms underlying cancer and non cancer pain, and could also worsen pain for which they were used.

TLR4 addiction addiction 32014377 As a conclusion, the antagonism of TLR4 could provide therapeutic value in the treatment of stress induced addiction. TLR4 drug amphetamine 31935095 Exploring Methamphetamine Nonenantioselectively Targeting Toll like Receptor 4/Myeloid Differentiation Protein 2 by in Silico Simulations and Wet Lab Techniques. TLR4 drug amphetamine 31935095 Methamphetamine (METH) is one of the highly addictive nonopioid psychostimulants, acting as a xenobiotic associated molecular pattern (XAMP) to target TLR4 and activate microglia. TLR4 addiction addiction 31935095 Methamphetamine (METH) is one of the highly addictive nonopioid psychostimulants, acting as a xenobiotic associated molecular pattern (XAMP) to target TLR4 and activate microglia. TLR4 drug amphetamine 31935095 However, the molecule recognition of METH by innate immune receptor TLR4/MD 2 is not well understood. TLR4 drug amphetamine 31935095 METH exists in two enantiomeric forms, and it is unclear whether the TLR4 innate immune recognition with METH is stereoselective. TLR4 drug amphetamine 31935095 Herein, molecular dynamics (MDs) simulations were performed to dissect the recognition of (+) METH and ( ) METH by TLR4/MD 2 at the atomic level. TLR4 drug amphetamine 31935095 Computational simulations indicate that METH binds into the interaction interface between MD 2 as well as TLR4* that is from the adjacent copy of TLR4 MD 2, therefore stabilizing the active heterotetramer (TLR4/MD 2)2 complex. TLR4 drug amphetamine 31935095 The calculated binding free energies and potential of mean force (PMF) values show that ( ) METH and (+) METH have similar TLR4/MD 2 binding affinity. TLR4 drug amphetamine 31935095 Further dynamics analyses of bindings with TLR4/MD 2 indicate that ( ) METH and (+) METH behave similarly. TLR4 drug amphetamine 31935095 Unlike the stereoselective neuron stimulating activities of METH, no enantioselectivity was observed for METH interacting with TLR4/MD 2 complex as well as activating TLR4 signaling. TLR4 drug amphetamine 31935095 Compared to METH, AMPH showed much weaker interactions with TLR4/MD 2, indicating that the substituted methyl group is critical in the molecular recognition of METH by TLR4/MD 2. TLR4 drug amphetamine 31935095 In all, this study provides molecular insight into the innate immune recognition of METH, which demonstrates that METH could be nonenantioselectively sensed by TLR4/MD 2. TLR4 drug opioid 31921165 Beginning with a paper published in 2005, evidence was presented that morphine is immune stimulating via binding to MD2, a molecule associated with Toll like Receptor 4 (TLR4), the receptor for bacterial lipopolysaccharide (LPS). TLR4 drug opioid 31921165 Beginning with a paper published in 2005, evidence was presented that morphine is immune stimulating via binding to MD2, a molecule associated with Toll like Receptor 4 (TLR4), the receptor for bacterial lipopolysaccharide (LPS). TLR4 drug opioid 31921165 Since engagement of TLR4 is universally accepted to result in immune activation by up regulation of NF κB, if morphine were binding to TLR4, it would be predicted that opioids would have been found to be pro inflammatory, which they were not. TLR4 drug opioid 31921165 Further, morphine is immunosuppressive in mice with a defective TLR4 receptor. TLR4 drug opioid 31921165 It is proposed that an occult variable in experiments where morphine is being proposed to activate TLR4 is actually underlying sepsis induced by the opioid. TLR4 drug opioid 31879851 morphine exposure led to increased expression of HMGB1, Toll like receptor 4 (TLR4), and receptor for advanced glycation end products (RAGE) and their mRNAs in the dorsal horn. TLR4 drug opioid 31879851 morphine exposure led to increased expression of HMGB1, Toll like receptor 4 (TLR4), and receptor for advanced glycation end products (RAGE) and their mRNAs in the dorsal horn. TLR4 drug opioid 31879851 Morphine challenge also promoted HMGB1 expression and release in cultured spinal neurons, but these effects were inhibited by TAK 242, naloxone (antagonists of TLR4), and TLR4 siRNA. TLR4 drug opioid 31879851 Together, these results suggest that morphine mediated upregulation of spinal HMGB1 contributes to analgesic tolerance and hyperalgesia via activation of TLR4/NF κB signaling, and the HMGB1 inhibitor might be a promising adjuvant to morphine in the treatment of intractable pain in the clinic. TLR4 drug opioid 31775878 The methylation of genes coding for the Toll like receptor 4 (TLR4) as a major mediator of glial contributions to persistent pain or for the μ opioid receptor (OPRM1) was analyzed and its association with the pain phenotype was compared with that conferred by global genome wide DNA methylation assessed via quantification of the methylation in the retrotransposon LINE1.

TLR4 drug alcohol 21352907 Our recent results have demonstrated that ethanol is capable of activating glial TLR4 receptors and that the elimination of these receptors in mice protects against ethanol induced glial activation, induction of inflammatory mediators and apoptosis. TLR4 drug alcohol 21352907 This study was designed to assess whether ethanol induced inflammatory damage causes behavioral and cognitive consequences, and if behavioral alterations are dependent of TLR4 functions. TLR4 drug alcohol 21352907 Mice lacking TLR4 receptors are protected against ethanol induced inflammatory damage, and behavioral associated effects. TLR4 drug alcohol 21352907 These results provide the first evidence of the role that TLR4 functions play in the behavioral consequences of alcohol induced inflammatory damage and suggest that the epigenetic modifications mediated by TLR4 could contribute to short or long term alcohol induced behavioral or cognitive dysfunctions. TLR4 drug psychedelics 21269783 MDMA could limit the IL 27 response of HV 68 infected or LPS exposed macrophages and dendritic cells in vitro and in vivo, demonstrating the ability of this drug to alter normal cytokine responses in the context of a viral infection and/or a TLR4 agonist. TLR4 drug alcohol 21091930 Chronic ethanol exposure sensitizes Kupffer cells to activation by lipopolysaccharides via toll like receptor 4. TLR4 drug alcohol 20870739 Alcohol and LPS significantly inhibited PSC apoptosis in vitro, and the effect of LPS on PSC apoptosis could be blocked by Toll like receptor 4 small interfering RNA. TLR4 drug alcohol 20624996 Thus, the effects of ethanol responsible for lethal outcome in sepsis are not dependent on inhibition of TLR4 signaling, as we and others had previously suspected. TLR4 drug alcohol 20608903 Decreased pulmonary inflammation following ethanol and burn injury in mice deficient in TLR4 but not TLR2 signaling. TLR4 drug alcohol 20608903 Wild type, TLR2, and TLR4 knockout mice were treated with vehicle or a single binge dose of ethanol (1.11 g/kg) and subsequently given a sham or burn injury. TLR4 addiction intoxication 20608903 Wild type, TLR2, and TLR4 knockout mice were treated with vehicle or a single binge dose of ethanol (1.11 g/kg) and subsequently given a sham or burn injury. TLR4 drug alcohol 20608903 Consistent with these findings, pulmonary levels of KC and IL 6 were increased in wild type mice following burn and ethanol compared to burn injury alone as well as to their TLR4 knockout counterparts. TLR4 drug alcohol 20608903 These data suggest that TLR4 signaling is a crucial contributory component in the exuberant inflammation after ethanol and burn injury. TLR4 drug alcohol 20238399 Chronic ethanol exposure sensitizes Kupffer cells to activation by lipopolysaccharide via Toll like receptor 4. TLR4 drug alcohol 21525758 For example, we showed that in alcoholic liver disease, the MyD88 independent, IRF3 dependent TLR4 cascade plays a role in steatosis and inflammation. TLR4 drug alcohol 19765273 Considering evidence that signaling can be very different in vitro and in vivo, the present study was conducted to determine if effects of ethanol on TLR4 signaling reported for cells in culture or cells removed from ethanol treated mice and stimulated in culture also occur when ethanol treatment and TLR4 activation occur in vivo. TLR4 drug alcohol 19765273 Ethanol suppressed production of most pro inflammatory cytokines to a similar degree as it inhibited key TLR4 signaling events. TLR4 drug opioid 19762094 Such effects can occur, not via classical opioid receptors, but rather via non stereoselective activation of toll like receptor 4 (TLR4), a recently recognized key glial receptor participating in neuropathic pain as well. TLR4 drug opioid 19762094 Such effects can occur, not via classical opioid receptors, but rather via non stereoselective activation of toll like receptor 4 (TLR4), a recently recognized key glial receptor participating in neuropathic pain as well. TLR4 drug opioid 19762094 This discovery identifies a means for separating the beneficial actions of opioids (opioid receptor mediated) from the unwanted side effects (TLR4/glial mediated) by pharmacologically targeting TLR4. TLR4 drug opioid 19679181 Evidence that opioids may have toll like receptor 4 and MD 2 effects. TLR4 drug opioid 19679181 Morphine non stereoselectively induced TLR4 signaling in vitro, blocked by a classical TLR4 antagonist and non stereoselectively by naloxone. TLR4 drug opioid 19679181 Pharmacological blockade of TLR4 signaling in vivo potentiated acute intrathecal morphine analgesia, attenuated development of analgesic tolerance, hyperalgesia, and opioid withdrawal behaviors. TLR4 addiction withdrawal 19679181 Pharmacological blockade of TLR4 signaling in vivo potentiated acute intrathecal morphine analgesia, attenuated development of analgesic tolerance, hyperalgesia, and opioid withdrawal behaviors. TLR4 drug opioid 19679181 TLR4 opposition to opioid actions was supported by morphine treatment of TLR4 knockout mice, which revealed a significant threefold leftward shift in the analgesia dose response function, versus wildtype mice. TLR4 drug opioid 19679181 A range of structurally diverse clinically employed opioid analgesics was found to be capable of activating TLR4 signaling in vitro. TLR4 drug opioid 19679181 Selectivity in the response was identified since morphine 3 glucuronide, a morphine metabolite with no opioid receptor activity, displayed significant TLR4 activity, whilst the opioid receptor active metabolite, morphine 6 glucuronide, was devoid of such properties. TLR4 drug opioid 19679181 These data provide evidence that select opioids may non stereoselectively influence TLR4 signaling and have behavioral consequences resulting, in part, via TLR4 signaling. TLR4 drug alcohol 18958703 Different effects of acute and chronic ethanol on LPS induced cytokine production and TLR4 receptor behavior in mouse peritoneal macrophages. TLR4 drug opioid 17982582 Here we demonstrate that selective acute antagonism of TLR4 results in reversal of neuropathic pain as well as potentiation of opioid analgesia. TLR4 drug opioid 17982582 Moreover, a novel antagonism of TLR4 by (+) and ( ) isomer opioid antagonists has now been characterized, and both antiallodynic and morphine analgesia potentiating activity shown. TLR4 drug opioid 17982582 Opioid agonists were found to also possess TLR4 agonistic activity, predictive of glial activation. TLR4 drug alcohol 17127267 Ethanol intake enhances inflammatory mediators in brain: role of glial cells and TLR4/IL 1RI receptors. TLR4 drug alcohol 17127267 TLR4/IL 1RI receptors may be involved in ethanol mediated inflammatory signaling, since blocking these receptors abolishes the production of ethanol induced inflammatory mediators and cell death. TLR4 drug alcohol 17127267 We propose that at low physiologically relevant concentrations, ethanol facilitates TLR4/IL 1RI recruitment into lipid rafts microdomains, leading to the activation and signaling of these receptors. TLR4 drug alcohol 17127267 In summary, current results suggest that TLR4/ IL 1RI are important targets of ethanol induced inflammatory brain damage. TLR4 drug alcohol 16385231 Here, we show that IRAK, one of signaling molecules of TLR 4, regulates tolerance and sensitization to LPS and acute ethanol increases in IRAK expression through a mechanism dependent upon oxidant production. TLR4 addiction sensitization 16385231 Here, we show that IRAK, one of signaling molecules of TLR 4, regulates tolerance and sensitization to LPS and acute ethanol increases in IRAK expression through a mechanism dependent upon oxidant production. TLR4 drug alcohol 16126318 Additional experiment showed that chronic ethanol exposure significantly increased plasma endotoxin level and hepatic CD14 and TLR 4 mRNA expression, all of which were blocked by elimination of Gram negative bacteria and endotoxin with antibiotics. TLR4 drug alcohol 15528012 It has been reported that acute administration of ethanol suppresses responses mediated through TLR3 and TLR4. IL10 drug opioid 32113469 Furthermore, spinal cinobufagin induced mechanical antiallodynia was inhibited by the pretreatment with intrathecal injection of the microglial inhibitor minocycline, IL 10 antibody, β endorphin antiserum and specific μ opioid receptor antagonist CTAP. IL10 addiction withdrawal 31589333 After 1 day of withdrawal, IL 18 was reduced, and IP 10 was elevated, whereas both IP 10 and IL 10 were elevated at 28 days following withdrawal. IL10 addiction withdrawal 31589333 In the frontal cortex, adolescent EtOH exposure induced an increase in IL 1β at day 35, and 28 days of withdrawal, and IL 10 was increased after 28 days of withdrawal. IL10 drug amphetamine 30793820 The aim of this study was to assess whether CBD prevents reinstatement of METH through change of gene expression of cytokines such as interleukin 1β, interleukin 6, interleukin 10, and tumor necrosis factor α (TNF α) in extinguished rats. IL10 addiction relapse 30793820 The aim of this study was to assess whether CBD prevents reinstatement of METH through change of gene expression of cytokines such as interleukin 1β, interleukin 6, interleukin 10, and tumor necrosis factor α (TNF α) in extinguished rats. IL10 addiction intoxication 30625475 Binge like consumption resulted in a 67% decrease in IL 10 immunoreactivity but had no effect on IL 4 or IL 6 compared with the water drinking control group. IL10 addiction intoxication 30485380 Pulmonary cytokine expression (TNF α, GM CSF) decreased, while splenic cytokine (IL 10) increased in binge drunk mice. IL10 drug alcohol 29733875 We measured the acute concentrations and dynamics of lipoxins LxA4 and LxB4 and the interleukins IL 4, IL 5, IL 9, IL 10, and IL 13 in the serum of patients treated with methyl alcohol poisoning and the follow up concentrations in survivors two years after discharge from the hospital. IL10 drug alcohol 29656414 Symptom severity, alcohol use, cytokine (plasma tumor necrosis factor α and C reactive protein [CRP], transforming growth factor β1 [TGF β1], interleukin 8 [IL 8], IL 10), and plasma BDNF levels were regularly assessed. IL10 drug alcohol 29500107 Among people with only an alcohol use disorder, IL 6 was positively associated with depression and psychological distress scores, and IL 10 was negatively associated with anxiety score. IL10 drug alcohol 29163491 On the contrary, iNKT cell deficient Jα18 / or interleukin 10 (IL 10) / mice showed fewer alcoholic steatosis, along with the recovered number and IFN γ release of hepatic NK cells, and exogenous IL 10 injection was sufficient to compensate for iNKT cell deficiency. IL10 drug alcohol 29163491 On the contrary, iNKT cell deficient Jα18 / or interleukin 10 (IL 10) / mice showed fewer alcoholic steatosis, along with the recovered number and IFN γ release of hepatic NK cells, and exogenous IL 10 injection was sufficient to compensate for iNKT cell deficiency. IL10 drug alcohol 29163491 Importantly, adoptive transfer of iNKT cells purified from normal but not IL 10 / mice resulted in suppression of the number and functions of NK cells and aggravated alcoholic liver injury in Jα18 / mice, indicating that IL 10 producing iNKT (NKT10) cells are the regulators on NK cells. IL10 drug opioid 28697991 In the morphine abuser, a decrease in pain threshold, an increase in IL 6 and a decrease in IL 10 levels were evident compared with non abuser subjects. IL10 drug alcohol 28675117 The alcohol group demonstrated decreased basal IL 10 compared with controls particularly following exposure to alcohol cue. IL10 drug alcohol 28669319 Our aim is to describe changes in serum concentration for the pro inflammatory factors TNF α, IFN γ, IL 1β, IL 8, IL 6, IL 10, IL 12 and MCP 1, for the satiety factor leptin and for factors associated with neuronal changes, neuron specific enolase (NSE) and glial activation S100 beta protein (S100 β), and explore their association with abstinence in alcohol dependent subjects after withdrawal.

IL10 drug amphetamine 28621212 RAW264.7 macrophages tended to switch to the M1 phenotype, releasing more nitric oxide and proinflammatory cytokines, including tumor necrosis factor α (TNFα), interleukin (IL) 12, and IL 1β, while decreasing the release of anti inflammatory cytokine IL 10 after treatment with Meth. IL10 drug amphetamine 28621212 Meth upregulated the gene expression of IL 6, IL 1β, and TNFα and downregulated the expression of Arg 1, IL 10, and KLF4. IL10 drug alcohol 28568647 Besides, alcohol treatment increased brain derived neurotrophic factor and interleukin 10 levels in prefrontal cortex, which was not reverted by P. incarnata. IL10 drug opioid 28436446 Opioid Self Administration is Attenuated by Early Life Experience and Gene Therapy for Anti Inflammatory IL 10 in the Nucleus Accumbens of Male Rats. IL10 drug opioid 28436446 Previous work has shown that a neonatal handling procedure in rats (which promotes enriched maternal care) attenuates morphine conditioning, reduces morphine induced glial activation, and increases microglial expression of the anti inflammatory cytokine interleukin 10 (IL 10).

IL10 drug alcohol 27640210 Furthermore, the ability of IL 10 to modulate ethanol consumption was tested using site directed pharmacology. IL10 drug alcohol 27640210 Immunohistochemistry analyses determined that ethanol decreased IL 10 by 50 % in the basolateral amygdala (BLA) but had no effect on IL 4. IL10 drug alcohol 27640210 Finally, bilateral infusions of IL 10 into the BLA, but not CeA, reduced binge like drinking and corresponding blood ethanol concentrations without impacting either locomotor activity or anxiety like behavioral correlates. IL10 addiction intoxication 27640210 Finally, bilateral infusions of IL 10 into the BLA, but not CeA, reduced binge like drinking and corresponding blood ethanol concentrations without impacting either locomotor activity or anxiety like behavioral correlates. IL10 drug alcohol 27640210 Together, these data support the idea that alcohol abuse dysregulates specific anti inflammatory cytokines; however, ameliorating alcohol induced effects on cytokines, like IL 10, may prove to be an effective therapy in curbing excessive consumption. IL10 addiction intoxication 27455577 It was established in experiments on noninbred albino rats that the acute intoxication with methanol (1.0 LD50) decreased cellular and humoral immune responses, Th2 lymphocyte activity (to a greater extent as compared to the function of Th1 cells), reduced the blood concentration of immunoregulatory (IFN g, IL 2, IL 4) and proinflammatory (TNF, IL 1b, IL 6) cytokines on the average by 36.5% (p < 0.05), and did not affect the content of anti inflammatory cytokines (IL 10, IL 13).

IL10 drug alcohol 27016017 Role of interleukin 10 (IL 10) in regulation of GABAergic transmission and acute response to ethanol. IL10 addiction withdrawal 27016017 Recent evidence suggests that interleukin 10 (IL 10), an anti inflammatory cytokine, is upregulated during withdrawal from chronic EtOH exposure. IL10 addiction withdrawal 27016017 Recent evidence suggests that interleukin 10 (IL 10), an anti inflammatory cytokine, is upregulated during withdrawal from chronic EtOH exposure. IL10 addiction intoxication 27016017 These results suggest that EtOH causes an early release of IL 10 in the brain, which may contribute to neuronal hyperexcitability as well as disturbed sleep seen after binge exposure to EtOH. IL10 drug alcohol 27016017 These results also identify IL 10 signaling as a potential therapeutic target in alcohol use disorders and other CNS disorders where GABAergic transmission is altered. IL10 drug amphetamine 26322025 In addition, the serum pro inflammatory (TNF, IL12 p70, IL1β, IL 6, and KC GRO) and Th2 (IL 2, IL 10, and IL 4) cytokine profiles were also altered in the presence of METH.

IL10 addiction sensitization 25524712 Prior studies have shown that exposure to lead is associated with atopic sensitization and modulation of several cytokines (eg, interleukin [IL] 12, IL 10, interferon [IFN] γ, and IL 4 production) and with T cell dysregulation and bias toward T helper 2 (Th2) activity. IL10 drug alcohol 25446642 Effect of repeated alcohol exposure during the third trimester equivalent on messenger RNA levels for interleukin 1β, chemokine (C C motif) ligand 2, and interleukin 10 in the developing rat brain after injection of lipopolysaccharide. IL10 drug alcohol 25446642 Conversely, LPS only minimally affected IL 10 mRNA expression and there were no significant differences between air and alcohol exposed rats.

IL10 drug opioid 24643510 Moreover, there was a significant difference in morphine tolerance induction between the AA and control rats, and our results also demonstrated that IL 10 played an important role in tolerance induction process. IL10 drug opioid 24643510 On the other hand, it seems that increased level of serum IL 10 may affect morphine tolerance development during inflammation.

ADH1B drug alcohol 21848961 The prevalence of comorbid psychiatric disorders, including major depression, eating disorder, panic disorder, and borderline personality disorder, was significantly higher in female alcoholics with inactive ALDH2 or superactive ADH1B than in those with active ALDH2 or normal ADH1B. ADH1B drug alcohol 21635275 No evidence for association with the alcohol dependence diagnosis was observed, but an SNP in exon 9 of ADH1B (rs2066702; ADH1B*3) and an SNP at the 5' end of ADH4 (rs3762894) showed significant evidence of association with the presence of withdrawal symptoms (p = 0.0018 and 0.0012, respectively).

ADH1B drug alcohol 20477764 ADH1B*3 was associated with higher levels of sedation and a sharper increase in pulse rate immediately following alcohol consumption. ADH1B drug alcohol 20477764 These findings suggest that the lower rates of alcohol dependence in those with ADH1B*3 alleles may be because of differences in alcohol response, particularly increased sedation. ADH1B addiction dependence 20477764 These findings suggest that the lower rates of alcohol dependence in those with ADH1B*3 alleles may be because of differences in alcohol response, particularly increased sedation. ADH1B drug alcohol 20401433 The purpose of this study was to investigate the differences, if present, in the allele and genotype frequency of alcohol dehydrogenase 1B (ADH1B), ADH1C and the microsomal ethanol oxidizing system (MEOS/CYP2E1) between alcohol dependent individuals and controls and also to determine if these genotypes cause a difference in the age at which the patients become alcohol dependent. ADH1B drug alcohol 20401433 The allele and genotype frequencies of ADH1B, ADH1C, and CYP2E1 were determined in 204 alcohol dependent men and 172 healthy volunteers who do not drink alcohol (control group).

ADH1B drug opioid 20077761 The genotype frequencies of the ADH2 and ALDH2 gene polymorphisms as well as the A118G polymorphism of the mu opioid receptor gene (OPRM1) in Korean men and women with alcohol dependence (AD) were compared with those of normal healthy (NH) Korean men and women at a low risk for alcoholism. ADH1B addiction dependence 20077761 The genotype frequencies of the ADH2 and ALDH2 gene polymorphisms as well as the A118G polymorphism of the mu opioid receptor gene (OPRM1) in Korean men and women with alcohol dependence (AD) were compared with those of normal healthy (NH) Korean men and women at a low risk for alcoholism. ADH1B drug alcohol 20077761 These results suggest that, while the risk of alcoholism in Korean men is predominantly affected by the presence of the ALDH2 1/1 genotype, the risk of alcoholism in Korean women is primarily associated with the ADH2 1/1 genotype and G carrier genotype of the OPRM1 A118G polymorphism.

ADH1B addiction dependence 19014920 Functional variant alleles ADH1B*2 and ALDH2*2 have been consistently replicated to show protection against developing alcohol dependence. ADH1B drug alcohol 19014920 Multiple logistic regression analyses suggest that ADH1B*2 and ALDH2*2 may independently influence the risk for alcoholism. ADH1B drug alcohol 19014920 Correlations of blood ethanol and acetaldehyde concentrations, cardiovascular hemodynamic responses, and subjective perceptions have been investigated in men with different combinatorial ADH1B and ALDH2 genotypes following challenge with ethanol for a period of 130 min. ADH1B addiction dependence 18996923 There were study wide significant associations (P<2.3 x 10( 4)) between ADH1B Arg48His (rs1229984) and flushing and consumption, but only nominally significant associations (P<0.01) with dependence. ADH1B drug alcohol 18996923 After controlling for rs1229984, an independent association was observed between rs1042026 (ADH1B) and alcohol intake (P=4.7 x 10( 5)) and suggestive associations (P<0.001) between alcohol consumption phenotypes and rs1693482 (ADH1C), rs1230165 (ADH5) and rs3762894 (ADH4). ADH1B drug alcohol 18996923 These results bridge the gap between DNA sequence variation and alcohol related behavior, confirming that the ADH1B Arg48His polymorphism affects both alcohol related flushing in Europeans and alcohol intake.

ADH1B drug alcohol 18299763 The current study examined self report level of response to alcohol, ALDH2 and ADH1B, country of origin, and family history of alcoholism in 154 Chinese and 181 Korean American college students. ADH1B drug alcohol 18299763 This relationship remained significant after considering the effects of gender, height, weight, quantity and frequency of alcohol consumption (over the previous 90 days), ALDH2 genotype, ADH1B genotype, country of origin, and first degree family history of alcohol dependence.

ADH1B drug alcohol 17885622 The subjects were divided into 3 combinatorial genotypic groups of alcohol dehydrogenase (ADH) and ALDH, that is, ALDH2*1/*1 ADH1B*1/*1 ADH1C*1/*1 (n=8), ALDH2*1/*1 ADH1B*2/*2 ADH1C*1/*1 (n=8), and ALDH2*1/*2 ADH1B*2/*2 ADH1C*1/*1 (n=16). ADH1B drug alcohol 17718398 Studies have demonstrated that a certain variant of the gene encoding ADH1B (ADH1B*3) is associated with a reduced risk of alcoholism in Afro Trinidadians, as is a variant of the gene encoding ADH1C (i.e., ADH1C*1) in Indo Trinidadians.

ADH1B drug alcohol 17454860 We determined the allele and genotype of ADH2, ADH3 and ALDH2 in 198 subjects: 57 with alcohol cirrhosis, 44 with alcohol chronic pancreatitis and 43 "healthy alcoholics"; 54 healthy non drinkers served as controls. ADH1B drug alcohol 17454860 The ADH2*1 and the ADH3*1 alleles were statistically more common among patients who abuse alcohol in comparison with the controls. ADH1B drug alcohol 17454860 The ADH2*2 allele was not detected in any of the patients with chronic alcohol pancreatitis. ADH1B drug alcohol 17454860 The ADH2*1/*1 and the ADH3*1/*1 genotypes were statistically significantly more common among the patients who abuse alcohol than in the control group. ADH1B drug alcohol 17250612 Two of the class I alcohol dehydrogenase (ADH) genes located on chromosome 4 (ADH1B and ADH1C) encode for multiple isozymes that differ in their kinetic properties. ADH1B drug alcohol 17250612 ADH1B(*)2 (found mostly in individuals of East Asian and Jewish descent) and ADH1B(*)3 (found mostly in individuals of African decent) alleles encode for a more active enzyme variants than ADH1B(*)1 and the presence of these alleles has been associated with protection from alcohol dependence.

ADH1B drug alcohol 17250612 The specific aim of the study was to investigate the associations between ADH1B alleles and alcohol dependence, drinking history, and liver function in individuals from the 2 major ethnic groups of Trinidad (individuals of African and East Indian ancestry). ADH1B addiction dependence 17250612 The specific aim of the study was to investigate the associations between ADH1B alleles and alcohol dependence, drinking history, and liver function in individuals from the 2 major ethnic groups of Trinidad (individuals of African and East Indian ancestry). ADH1B drug alcohol 17250612 African participants with at least 1 ADH1B(*)3 allele were found to be significantly less likely to be alcohol dependent (p<0.018), and to have lower alcohol consumption levels (p<0.05). ADH1B drug alcohol 17250612 Among those participants who were alcohol dependent, ADH1B(*)3 was associated with significantly higher levels of ALT (p<0.05). ADH1B drug alcohol 17250612 This study suggests, in this sample of Trinidadians, that the ADH1B(*)3 allele is associated with protection from the development of alcoholism but is also associated with enhanced risk for elevated serum ALT levels in those individuals who do become alcohol dependent.

ADH1B drug alcohol 17134660 Only three individuals had an ADH1B*2 allele (one Indo TT alcohol dependent, two Indo TT controls). ADH1B drug alcohol 16930209 Variations in the ADH1B and ADH1C genes may influence the LR to alcohol by increasing levels of acetaldehyde during alcohol metabolism, although most data on this question come from Asian populations. ADH1B drug alcohol 16930209 Participants with the ADH1B*1/*2 genotype had a higher LR to alcohol early in the alcohol challenge (i.e., 30, 60, and 90 minutes after drinking) as measured by both alcohol related changes in subjective feelings of intoxication and body sway, even when controlling for sex and Russian/Eastern European ancestry. ADH1B addiction intoxication 16930209 Participants with the ADH1B*1/*2 genotype had a higher LR to alcohol early in the alcohol challenge (i.e., 30, 60, and 90 minutes after drinking) as measured by both alcohol related changes in subjective feelings of intoxication and body sway, even when controlling for sex and Russian/Eastern European ancestry. ADH1B drug alcohol 16930209 These findings suggest that studies searching for genes relating to the LR to alcohol as a vulnerability factor for AUDs should consider controlling for ADH1B genotype, as the ADH1B*2 allele could obscure the impact of other genetic polymorphisms.

ADH1B drug alcohol 16571603 Haplotype tag SNPs were selected for the block in the ADH4 gene that provided evidence of association and subsequently used in association analysis; the haplotype was significantly associated with alcoholism (P=0.01) There was weaker evidence that variations in ADH1A and ADH1B might also play a role in modifying risk. ADH1B drug alcohol 16404797 The ADH1B*2, ADH1B*3, and ADHlC*i alleles, found in varying prevalence in different ethnic groups, have also been associated with lower rates of alcohol dependence. ADH1B addiction dependence 16404797 The ADH1B*2, ADH1B*3, and ADHlC*i alleles, found in varying prevalence in different ethnic groups, have also been associated with lower rates of alcohol dependence. ADH1B drug alcohol 16404797 The hypothesized mechanism underlying the associations of the ADH1B and ALDH2 polymorphisms with alcohol dependence is that the isoenzymes encoded by these alleles lead to an accumulation of acetaldehyde during alcohol metabolism.

ADH1B drug alcohol 16125912 One hundred and eleven male patients with alcohol dependence and 123 nonalcoholic healthy men were tested for the genetic polymorphisms of alcohol dehydrogenase 2 (ADH2), aldehyde dehydrogenase 2 (ALDH2), serotonin transporter (5 HTT) and dopamine transporter (DAT1). ADH1B addiction dependence 16125912 One hundred and eleven male patients with alcohol dependence and 123 nonalcoholic healthy men were tested for the genetic polymorphisms of alcohol dehydrogenase 2 (ADH2), aldehyde dehydrogenase 2 (ALDH2), serotonin transporter (5 HTT) and dopamine transporter (DAT1). ADH1B drug alcohol 16125912 There were significant differences in genotype frequencies of ADH2 C992G and A13543G SNPs between alcoholic patients with family history of alcohol dependence (familial) and alcoholic patients without family history (non familial). ADH1B addiction dependence 16125912 There were significant differences in genotype frequencies of ADH2 C992G and A13543G SNPs between alcoholic patients with family history of alcohol dependence (familial) and alcoholic patients without family history (non familial). ADH1B drug alcohol 23105541 Subtypes of ADH2 gene in alcoholics. ADH1B drug alcohol 23105541 In the present study, genetic variation was detected in the subtypes of gene, coding for the alcohol metabolizing enzyme Alcohol Dehydrogenase 2 (ADH2). ADH1B drug alcohol 23105541 Blood samples were collected from the alcoholic and non alcoholic subjects and genotyping was performed using PCR RFLP (Polymerase Chain Reaction Restriction Fragment Length Polymorphism), analysis to determine genetic polymorphisms in the ADH2 gene subtypes. ADH1B drug alcohol 23105541 The three subtypes of ADH2 gene (ADH2.1, ADH2.2 and ADH2.3) were found in both alcoholics (Family History Positive and Family History Negative) as well as non alcoholics. ADH1B drug alcohol 15957670 Associations of ALDH2 and ADH1B genotypes with response to alcohol in Asian Americans. ADH1B drug alcohol 15957670 Individuals with alcohol dependence are less likely to possess variant alleles of the alcohol metabolizing genes, aldehyde dehydrogenase (ALDH2*2) and alcohol dehydrogenase (ADH1B*2), than non alcohol dependent controls. ADH1B addiction dependence 15957670 Individuals with alcohol dependence are less likely to possess variant alleles of the alcohol metabolizing genes, aldehyde dehydrogenase (ALDH2*2) and alcohol dehydrogenase (ADH1B*2), than non alcohol dependent controls. ADH1B drug alcohol 15957670 Previous research has shown that individuals with ALDH2*2 demonstrate enhanced reactions to alcohol compared with those without this genetic variant, but evidence that ADH1B*2 is associated with a greater alcohol response is mixed. ADH1B drug alcohol 15957670 This study was designed to determine whether the ADH1B genotype is associated with more intense reactions to alcohol after controlling for the ALDH2 genotype. ADH1B drug alcohol 15957670 Among participants with the ALDH2*1/*1 genotype, there were no additional effects of the ADH1B genotype on any measures of response to alcohol. ADH1B drug alcohol 15957670 Among participants with the ALDH2*1/*2 genotype, those with the ADH1B*2/*2 genotype were more likely to experience alcohol induced vomiting and to report feeling less "great overall" 30 minutes after ingestion of alcohol than those with the ADH1B*1/*2 genotype. ADH1B drug alcohol 15957670 These findings are consistent with the hypothesis that there is an additional effect of ADH1B*2 on level of response to alcohol, but only among individuals with the ALDH2*1/*2 genotype. ADH1B drug alcohol 15863807 The authors examined the genetic polymorphisms of alcohol dehydrogenase 2 and 3 (ADH2 and ADH3) and aldehyde dehydrogenase (ALDH2) in patients diagnosed as having Cloninger's type I or type II alcoholism. ADH1B drug alcohol 15863807 Seventy two alcoholic men and 38 nonalcoholic, healthy men were tested for the distribution of genotypes and alleles of ADH2, ADH3, and ALDH2. ADH1B drug alcohol 15863807 The frequencies of ADH2*1 and ADH3*2 alleles were significantly higher in men with type II alcoholism than in men with type I alcoholism and healthy men.

ADH1B drug alcohol 15842823 Correlation between genotypes of ADH2 and ALDH2 and alcohol related diseases should be more important. ADH1B drug alcohol 15542751 The results revealed that (1) the less active allele of the ADH2 gene (ADH2*1) is associated with an increased risk for alcohol dependence, alcohol induced persistent amnestic disorder, alcohol withdrawal syndrome, and cancer of the upper GI tract; (2) the inactive allele of the ALDH2 gene (ALDH2*2) is associated with a decreased risk for alcohol dependence, and an increased risk for alcoholic polyneuropathy and cancer in the same region; and (3) these genetic variations modify clinical features of alcohol dependence.

ADH1B drug alcohol 15084894 We hypothesized that the ADH1B and ALDH2 genes might interact with the DRD2 gene and that the association between the DRD2 gene and alcohol dependence might be affected by different ADH1B and ALDH2 genotypes. ADH1B addiction dependence 15084894 We hypothesized that the ADH1B and ALDH2 genes might interact with the DRD2 gene and that the association between the DRD2 gene and alcohol dependence might be affected by different ADH1B and ALDH2 genotypes. ADH1B drug alcohol 15066702 Mexican Americans have a low frequency of the protective alleles ADH1B(*)2 and ALDH2(*)2 and a relatively high frequency of CYP2E1 c2, which is associated with early onset alcoholism. ADH1B drug alcohol 15041893 Among the multiple factors which influence these variations, genetic factors especially those related to the different alleles of ADH2 and ALDH2, are the most well known and are related to the development of alcohol dependence, particularly in some populations such as those of Asian origin.

ADH1B drug alcohol 14745297 There is growing evidence of a functional role of the ADH2*2 allele in alcohol drinking patterns among Jews, who have traditionally exhibited low rates of alcoholism and alcohol related problems. ADH1B drug alcohol 14745297 This study examined the effect of ADH2*2 on alcohol elimination rates (AER) under experimental conditions. ADH1B drug alcohol 14745297 The rate of alcohol elimination is significantly associated with the ADH2 genotype of Jewish males.

ADH1B drug alcohol 12824808 In Taiwan, about 70% of the Han Chinese population have the ADH2*2 allele and 50% show ALDH2*1/*2 or ALDH2*2/*2 genotypes, which offer protection against drinking behavior and the risk of developing alcoholism. ADH1B drug alcohol 12710951 To identify the association between the polymorphisms of genes encoding alcohol metabolizing enzymes and alcoholism, the alcohol dehydrogenase 2 (ADH2), alcohol dehydrogenase 3 (ADH3), aldehyde dehydrogenase 2 (ALDH2), and cytochrome P450 2E1 (CYP2E1) genes were studied in 101 male Mexican American alcoholics. ADH1B drug alcohol 12710951 The allele frequency of ADH2*2 (4.3%) and ALDH2*2 (0%), which are considered as protective alleles against alcohol drinking, is very low in Mexican Americans and no association is found between these alleles and alcohol dependence.

ADH1B drug alcohol 12505800 Two alcohol dehydrogenase genes (ADH2 and ADH3 on chromosome 4) and one aldehyde dehydrogenase gene (ALDH2 on chromosome 12) exhibit functional polymorphisms. ADH1B drug alcohol 12505800 The goal of this study was to determine whether any associations exist between the ADH2, ADH3, and ALDH2 polymorphisms and alcohol dependence in a group of Native Americans. ADH1B addiction dependence 12505800 The goal of this study was to determine whether any associations exist between the ADH2, ADH3, and ALDH2 polymorphisms and alcohol dependence in a group of Native Americans. ADH1B drug alcohol 12505800 A significant difference in the ADH2 allele distributions was found between alcohol dependent and non alcohol dependent participants. ADH1B drug alcohol 12505800 Those with alcohol dependence were significantly less likely to have the ADH2*3 allele (odds ratio=0.28) and significantly more likely to have the ADH2*1 allele (odds ratio=2.00) than those who were not alcohol dependent. ADH1B addiction dependence 12505800 Those with alcohol dependence were significantly less likely to have the ADH2*3 allele (odds ratio=0.28) and significantly more likely to have the ADH2*1 allele (odds ratio=2.00) than those who were not alcohol dependent. ADH1B drug alcohol 12505800 These results are consistent with genetic linkage studies showing protective associations for alcohol dependence and related behavior on chromosome 4 and suggest that ADH2 polymorphisms may account for these findings.

ADH1B drug alcohol 12500100 All participants completed the Time Line Follow Back, had blood drawn for genotyping at the alcohol dehydrogenase locus ADH2, and reported their religious affiliation and the number of religious services attended in the past year. ADH1B drug alcohol 12500100 In the total sample, individuals who possessed a variant alcohol dehydrogenase allele ADH2*2 were approximately half as likely to binge drink as those who did not possess this allele.

ADH1B drug alcohol 12351924 The ADH2*2 allele of the alcohol dehydrogenase 2 (ADH2) gene protects against alcoholism in Asians and is found in approximately 20% of Jews. ADH1B addiction dependence 12351924 We studied the relationship of ADH2*2 to DSM IV dependence severity in a random community sample of Israeli Ashkenazis, recent Russian immigrants (also Ashkenazis), and Sephardics. ADH1B drug alcohol 12351924 Controlling for group and other potentially confounding factors, ADH2*2 was associated with a lower lifetime DSM IV alcohol dependence severity, although this differed somewhat within groups.

ADH1B drug alcohol 11900616 Alcohol dehydrogenase ADH2 1 and ADH2 2 allelic isoforms in the Russian population correlate with type of alcoholic disease. ADH1B drug alcohol 11900616 The frequency ADH2 2 allele in the Moscow urban population and a correlation between the ADH2 2 allele, alcoholic dependence without cirrhosis, symptomatic alcoholic cirrhosis and status on hepatitis B and C infection have been studied. ADH1B addiction dependence 11900616 The frequency ADH2 2 allele in the Moscow urban population and a correlation between the ADH2 2 allele, alcoholic dependence without cirrhosis, symptomatic alcoholic cirrhosis and status on hepatitis B and C infection have been studied. ADH1B drug alcohol 11900616 There is a negative correlation between the ADH2 2 allele and alcohol misuse (both alcoholic dependence and alcoholic cirrhosis). ADH1B addiction dependence 11900616 There is a negative correlation between the ADH2 2 allele and alcohol misuse (both alcoholic dependence and alcoholic cirrhosis). ADH1B drug alcohol 11900616 In spite of the possession of the ADH2 2 allele (or genotype ADH2 1/2), alcohol misuse increases the risk of cirrhosis. ADH1B drug alcohol 11900616 At the same time, positive status for active hepatitis B, C or combined infection B + C (replication markers HBV DNA or HCV RNA) increases the risk for symptomatic alcoholic cirrhosis in alcohol abusing patients, independently of ADH2 genotype. ADH1B drug alcohol 11584143 In view of this association and the known genetic influences on both alcohol pharmacokinetics and alcohol dependence, it is probable that part of the heritability of dependence is mediated by genes (other than the known ADH2 and ADH3 polymorphisms) affecting alcohol metabolism.

ADH1B drug alcohol 11545539 In Asians, variation in the alcohol dehydrogenase (ADH2) gene relates to alcohol dependence, alcohol consumption, and reported alcohol related symptoms, even after controlling for variation in the aldehyde dehydrogenase (ALDH2) gene. ADH1B addiction dependence 11545539 In Asians, variation in the alcohol dehydrogenase (ADH2) gene relates to alcohol dependence, alcohol consumption, and reported alcohol related symptoms, even after controlling for variation in the aldehyde dehydrogenase (ALDH2) gene. ADH1B drug alcohol 11545539 The association of ADH2 polymorphisms with alcohol related behavior, however, has not been well characterized in non Asians. ADH1B drug alcohol 11545539 ADH2*2, however, was not related to alcohol use disorders, alcohol induced flushing and associated symptoms, number of binge drinking episodes in the past 90 days, maximum number of drinks ever consumed, or self reported levels of response to alcohol. ADH1B addiction intoxication 11545539 ADH2*2, however, was not related to alcohol use disorders, alcohol induced flushing and associated symptoms, number of binge drinking episodes in the past 90 days, maximum number of drinks ever consumed, or self reported levels of response to alcohol. ADH1B drug alcohol 11545539 Results suggest that Ashkenazic Jewish Americans with ADH2*2 alleles drink less frequently, which might contribute, in part, to the overall lower rates of alcoholism in this population. ADH1B drug alcohol 11315223 In men, effects of alcohol dehydrogenase ADH2*1/*2 genotype or high alcohol sensitivity (risk decreasing), and of history of childhood conduct disorder, or having monozygotic co twin or twin sister with AlcD (risk increasing) were significant and comparable in magnitude. ADH1B drug alcohol 10630602 An alcohol dependent patient was identified to be ALDH2*2/*2, ADH2*2/*2, and ADH3*1/*2. ADH1B drug alcohol 10630602 Logistic regression analysis of the combinatorial genotypes of ADH2 and ALDH2 in 420 alcohol dependent and 689 nonalcohol dependent subjects indicated that risk for alcoholism was 100 fold lower for the ADH2*2/*2 ALDH2*2/*2 individuals than the ADH2*1/*1 ALDH2*1/*1 individuals. ADH1B drug alcohol 10235293 The different genotypes at the genes encoding the enzymes involved in alcohol metabolism, class one alcohol dehydrogenase (ADH2 and ADH3) and mitochondrial aldehyde dehydrogenase (ALDH2), have previously been shown to confer different predispositions to the development of alcoholism in Chinese Han males (Thomasson et al., 1991; Chen WJ et al., 1996; Chen CC et al., unpublished data). ADH1B drug alcohol 10235293 Therefore, association studies of alcoholism in Chinese Han might be more sensitive if controlled for the genotypes of ADH2,ADH3, and ALDH2, when other loci, such as DRD2, are examined. ADH1B drug alcohol 10235293 These tests included considering the high risk (ADH2*1/*1; *1/*2; ADH3*1/*2; *2/*2; and ALDH2*1/*1) and the low risk (ADH2*2/*2; ADH3*1/*1; and ALDH2*1/*2; *2/*2) groups of alcoholics, as well as nonalcoholic controls. ADH1B drug alcohol 10235293 After stratification by the relevant genotypes of ADH2, ADH3, and ALDH2 no significant association exists between the genetic variants at the DRD2 locus and alcoholism in the Chinese Han population. ADH1B addiction dependence 9802529 ADH2 genotype had significant effects on both consumption and dependence in the men, but not in the women. ADH1B drug alcohol 9509496 Men with an ADH2 x 3 allele had significantly higher amplitude P3 components at placebo and also demonstrated more alcohol induced reductions in P3 amplitude than men with ADH2 x 1 alleles only. ADH1B drug alcohol 9373704 The purpose of this paper is to assemble and evaluate existing data on the effect of genetic variation in ADH2 and ADH3 on the risk of alcohol dependence, and on the risk of alcoholic liver disease. ADH1B addiction dependence 9373704 The purpose of this paper is to assemble and evaluate existing data on the effect of genetic variation in ADH2 and ADH3 on the risk of alcohol dependence, and on the risk of alcoholic liver disease. ADH1B drug alcohol 9373704 It is clear that possession of the ADH2 2 allele decreases the risk of alcohol dependence, but it increases the risk of alcoholic liver disease among alcoholics. ADH1B addiction dependence 9373704 It is clear that possession of the ADH2 2 allele decreases the risk of alcohol dependence, but it increases the risk of alcoholic liver disease among alcoholics. ADH1B drug alcohol 9373704 ADH3 variation also has significant effects on alcohol dependence, which may be due to linkage to ADH2; the ADH3 effect differs significantly between Asian and European subjects. ADH1B addiction dependence 9373704 ADH3 variation also has significant effects on alcohol dependence, which may be due to linkage to ADH2; the ADH3 effect differs significantly between Asian and European subjects. ADH1B drug alcohol 9066994 In this report we determined the genotypes for three genes, ADH2, ADH3, and ALDH2 among subjects with alcohol dependence (n = 159) and ethnically matched normal controls (n = 149) for the four largest aboriginal groups (Atayal, Ami, Bunun, and Paiwan) in Taiwan. ADH1B addiction dependence 9066994 In this report we determined the genotypes for three genes, ADH2, ADH3, and ALDH2 among subjects with alcohol dependence (n = 159) and ethnically matched normal controls (n = 149) for the four largest aboriginal groups (Atayal, Ami, Bunun, and Paiwan) in Taiwan. ADH1B drug alcohol 9066994 On an individual level, however, the genotypes controlling alcohol metabolism did not account for intragroup differences in vulnerability to alcoholism except in the case of ADH2 for the Ami ethnic group. ADH1B drug alcohol 8904964 The influences of estimated body water, recent drinking history, recent smoking history, polymorphism at the ADH2 and ADH3 loci, family history of alcoholism, and percentage Native American heritage on alcohol elimination rate were determined using multiple regression analyses. ADH1B drug nicotine 8904964 The influences of estimated body water, recent drinking history, recent smoking history, polymorphism at the ADH2 and ADH3 loci, family history of alcoholism, and percentage Native American heritage on alcohol elimination rate were determined using multiple regression analyses. ADH1B drug alcohol 8904964 There was also a nonsignificant trend for subjects with an ADH2*3 allele (n = 6) to have faster rates of alcohol elimination than those with ADH2*1 alleles only (n = 33). ADH1B drug alcohol 8773821 Alcohol metabolising genes and alcoholism among Taiwanese Han men: independent effect of ADH2, ADH3 and ALDH2. ADH1B drug alcohol 8773821 The association of ALDH2 and ADH2 with the development of alcoholism was found to be independent of each other and has been replicated in different Asian populations, while the effect of ADH3 is less studied. ADH1B drug alcohol 8773821 Multiple logistic regression was then applied to assess the contribution of ADH3 to alcoholism by controlling the effect of ALDH2 and ADH2. ADH1B drug alcohol 8773821 The results of multivariate analyses demonstrated that the odds ratios for an increment of one allele of ADH2*1, ADH3*2 and ALDH2*1 in the development of alcoholism were 4.18, 3.82, and 6.89, respectively. ADH1B drug alcohol 8651462 A comparison of the genotypes of ALDH2, ADH2, ADH3, and cytochrome P 4502E1 between alcoholics and nonalcoholics. ADH1B drug alcohol 8651462 Our study revealed differences in the allelic frequencies of the ALDH2, ADH2, and ADH3 loci between alcoholics and nonalcoholics. ADH1B drug alcohol 8651462 For alcoholics with both homozygous ALDH2*1/1 and heterozygous ALDH2*1/2 genotypes, it was found that ADH2 and ADH3 played important rates. ADH1B drug alcohol 8651462 Alcoholics with the heterozygous ALDH2*1/2 genotype showed a significantly higher frequency of ADH2*1/1 than ones with the homozygous ALDH2*1/1 genotype. ADH1B drug alcohol 8651462 We assume ADH2*1 plays an important role in the development of alcoholism in alcoholics with the heterozygous ALDH2*1/2 genotype. ADH1B drug alcohol 8591846 High incidence of ADH2*1/ALDH2*1 genes among Japanese alcohol dependents and patients with alcoholic liver disease. ADH1B drug alcohol 8591846 Genetic polymorphism of ADH2/ALDH2 in 66 cases of normal subjects, 90 cases of alcohol dependent, and 31 patients with alcoholic liver disease among Japanese has been analyzed using a polymerase chain reaction assay followed by a direct sequencing method, because ethanol is mainly catabolized by ADH and ALDH and less by cytochrome P450IIE1 and catalase. ADH1B drug alcohol 8591846 The incidence of both ADH2*1/*1 and ALDH2*1/*1 was significantly higher in patients with alcohol dependence and in patients with alcoholic liver disease when compared with that in control subjects. ADH1B addiction dependence 8591846 The incidence of both ADH2*1/*1 and ALDH2*1/*1 was significantly higher in patients with alcohol dependence and in patients with alcoholic liver disease when compared with that in control subjects. ADH1B drug alcohol 8591846 Genetic polymorphism of ADH2/ALDH2 in patients with alcoholic liver disease was not different from that of alcohol dependents. ADH1B drug alcohol 8591846 According to these results, not only ALDH2 gene, often claimed to be responsible for alcohol dependence among Japanese, but also ADH2 gene polymorphism, which modulates the metabolism of ethanol, play important roles in habitual alcohol intake behavior in Japanese patients and in some patients leads to alcoholic liver diseases. ADH1B addiction dependence 8591846 According to these results, not only ALDH2 gene, often claimed to be responsible for alcohol dependence among Japanese, but also ADH2 gene polymorphism, which modulates the metabolism of ethanol, play important roles in habitual alcohol intake behavior in Japanese patients and in some patients leads to alcoholic liver diseases. ADH1B drug alcohol 7943668 Low frequency of the ADH2*2 allele among Atayal natives of Taiwan with alcohol use disorders. ADH1B drug alcohol 7943668 Genetic variation at two polymorphic alcohol dehydrogenase loci, ADH2 and ADH3, and at the polymorphic mitochondrial aldehyde dehydrogenase locus, ALDH2, may influence the risk of developing alcoholism by modulating the rate of elimination of ethanol and the rate of formation and elimination of acetaldehyde. ADH1B drug alcohol 7943668 Among the Atayal, the group with alcohol use disorders (alcohol dependence and alcohol abuse) had a significantly lower frequency of the ADH2*2 allele (0.82) than those without alcohol use disorders (0.91). ADH1B addiction dependence 7943668 Among the Atayal, the group with alcohol use disorders (alcohol dependence and alcohol abuse) had a significantly lower frequency of the ADH2*2 allele (0.82) than those without alcohol use disorders (0.91). ADH1B drug alcohol 7943668 The ADH2*2 allele encodes the beta 2 subunit; isozymes containing beta 2 subunits oxidize alcohol faster in vitro than the beta 1 beta 1 isozyme encoded by ADH2*1. ADH1B drug alcohol 3189338 Genetic polymorphisms of two major alcohol metabolizing enzymes i.e., one of the class I alcohol dehydrogenase isozymes (ADH2) and the mitochondrial aldehyde dehydrogenase (ALDH2) exist in Japanese and other Orientals but not in Caucasians. ADH1B drug alcohol 3189338 We determined, by means of hybridization of genomic DNA samples with allele specific synthetic oligonucleotide probes, genotypes of the ADH2 and the ALDH2 loci of Japanese with alcoholic liver diseases and of control subjects. ADH1B drug alcohol 6321953 Seven cis dominant mutations leading to the overproduction of the glucose repressible alcohol dehydrogenase isozyme ADHII (structural gene, ADH2) in Saccharomyces cerevisiae have previously been shown to be due to insertion of a transposable element, Ty, in the 5' regulatory region of the ADH2 gene.

CYP2A6 addiction addiction 24305170 Nicotine, the main addictive ingredient in tobacco, is metabolically inactivated to cotinine primarily by the hepatic enzyme CYP2A6. CYP2A6 drug nicotine 24305170 Considerable genetic variation in the CYP2A6 gene results in large variation in the rates of nicotine metabolism, which in turn alters smoking behaviours (e.g. CYP2A6 drug nicotine 24305170 The CYP2A6 gene from African American phenotypically slow nicotine metabolizers was sequenced and seven novel variants were identified [CYP2A6*39 (V68M), CYP2A6*40 (I149M), CYP2A6*41 (R265Q), CYP2A6*42 (I268T), CYP2A6*43 (T303I), CYP2A6*44 (E390K), CYP2A6*44 (L462P)].

CYP2A6 drug nicotine 24127329 Genetic variations in CYP2A6 gene or genotypes associated with reduced synaptic serotonin activity may influence the success of smoking cessation treatment. CYP2A6 drug nicotine 24045616 Variants in two adjacent genes, EGLN2 and CYP2A6, influence smoking behavior related to disease risk via different mechanisms. CYP2A6 drug nicotine 24045616 Genome wide significant associations with cigarettes per day (CPD) and risk for lung cancer and chronic obstructive pulmonary disease (COPD) were previously reported in a region of 19q13, including CYP2A6 (nicotine metabolism enzyme) and EGLN2 (hypoxia response). CYP2A6 drug nicotine 24045616 Here, we demonstrate that when CYP2A6 and EGLN2 genotypes are analyzed together, the key EGLN2 variant, rs3733829, is not associated with nicotine metabolism independent of CYP2A6, but is nevertheless independently associated with CPD, and with breath carbon monoxide (CO), a phenotype associated with cigarette consumption and relevant to hypoxia. CYP2A6 drug nicotine 24045421 Impact of nicotine metabolism on nicotine's pharmacological effects and behavioral responses: insights from a Cyp2a(4/5)bgs null mouse. CYP2A6 drug nicotine 24045421 As a key step toward testing this hypothesis, we have studied nicotine metabolism and nicotine's pharmacological and behavioral effects in a novel knockout mouse model [named Cyp2a(4/5)bgs null] lacking a number of cytochrome P450 genes known to be or possibly involved in nicotine metabolism, including two Cyp2a and all Cyp2b genes. CYP2A6 drug nicotine 24045421 We found that, compared with wild type mice, the Cyp2a(4/5)bgs null mice showed >90% decreases in hepatic microsomal nicotine oxidase activity in vitro, and in rates of systemic nicotine clearance in vivo. CYP2A6 drug nicotine 24045421 Further comparisons of nicotine metabolism between Cyp2a(4/5)bgs null and Cyp2a5 null mice revealed significant roles of both CYP2A5 and CYP2B enzymes in nicotine clearance. CYP2A6 drug nicotine 24045421 Compared with the behavioral responses in wild type mice, the decreases in nicotine metabolism in the Cyp2a(4/5)bgs null mice led to prolonged nicotine induced acute pharmacological effects, in that null mice showed enhanced nicotine hypothermia and antinociception. CYP2A6 drug nicotine 24045421 Furthermore, we found that the Cyp2a(4/5)bgs null mice developed a preference for nicotine in a conditioned place preference test, a commonly used test of nicotine's rewarding effects, at a nicotine dose that was 4 fold lower than what was required by wild type mice. CYP2A6 drug nicotine 24045421 Thus, CYP2A/2B catalyzed nicotine clearance affects nicotine's behavioral response as well as its acute pharmacological effects in mice.

CYP2A6 drug nicotine 24033696 Further, only the effect of nicotine replacement, and not bupropion, varies with CYP2A6 defined metabolic function. CYP2A6 drug nicotine 24033696 The effect of nicotine replacement on continuous abstinence is moderated by the combined genetic risks from CYP2A6 and CHRNA5 (Wald = 7.44, d.f. CYP2A6 drug nicotine 24033696 Nicotine replacement therapy is effective among individuals with fast, but not slow, CYP2A6 defined nicotine metabolism.

Serial plasma nicotine concentrations and subjective and cardiovascular effects were measured, and genetic variation in the CYP2A6 gene, encoding the primary enzyme responsible for nicotine metabolism, was assessed. CYP2A6 drug nicotine 23933970 Toxicity and subjective and cardiovascular effects of nicotine were associated with the presence of reduced function CYP2A6 alleles, presumably reflecting slow nicotine metabolic inactivation.

CYP2A6 drug nicotine 22935730 CYP2A6 mRNA and protein levels and in vitro coumarin (selective CYP2A6 substrate) and nicotine metabolism were decreased by nicotine treatment but unaffected by ethanol. CYP2A6 drug alcohol 22935730 Combined ethanol and nicotine exposure decreased CYP2A6 mRNA and protein levels, as well as in vitro coumarin and nicotine metabolism, and increased CYP2B6 protein levels and in vitro bupropion metabolism, with no change in CYP2B6 mRNA levels. CYP2A6 drug nicotine 22935730 Combined ethanol and nicotine exposure decreased CYP2A6 mRNA and protein levels, as well as in vitro coumarin and nicotine metabolism, and increased CYP2B6 protein levels and in vitro bupropion metabolism, with no change in CYP2B6 mRNA levels. CYP2A6 drug nicotine 22935730 Chronic nicotine resulted in higher nicotine plasma levels achieved after nicotine administration, consistent with decreased CYP2A6. CYP2A6 drug alcohol 22935730 Thus, nicotine can decrease hepatic CYP2A6, reducing the metabolism of its substrates, including nicotine, whereas ethanol can increase hepatic CYP2B6, increasing the metabolism of CYP2B6 substrates.

CYP2A6 drug nicotine 22869927 In the studies presented here, we confirm that the nicotine Δ5'(1')iminium ion is an inactivator of both CYP2A6 and CYP2A13, and inactivation depends on time, concentration, and the presence of NADPH. CYP2A6 drug nicotine 22869927 These data are consistent with the characterization of the nicotine Δ5'(1')iminium ion as a mechanism based inactivator of both CYP2A13 and CYP2A6. CYP2A6 drug nicotine 22869927 We also confirm that both CYP2A6 and CYP2A13 catalyze the metabolism of the nicotine Δ5'(1')iminium ion to cotinine and provide evidence that both enzymes catalyze the sequential metabolism of the nicotine Δ5'(1')iminium ion.

CYP2A6 drug nicotine 19415821 Gene gene interactions of CYP2A6 and MAOA polymorphisms on smoking behavior in Chinese male population. CYP2A6 drug nicotine 19415821 In this study, we investigated the association and multilocus gene gene interactions of cytochrome P450 2A6 (CYP2A6), dopamine beta hydroxylase (DBH), catechol O methyl transferase (COMT), and monoamine oxidase A (MAOA) polymorphisms with smoking behavior in a community based Chinese male population. CYP2A6 drug nicotine 19415821 Statistically significant trends were shown for increased risk of smoking initiation in participants with CYP2A6*1B/CYP2A6*1B genotypes compared with those with CYP2A6*1A/CYP2A6*1A genotypes [odds ratio (OR)=3.5, 95% confidence interval (CI)= 1.5 8.1], and participants with CYP2A6*1/CYP2A6*1 genotypes were at higher risk of smoking initiation (OR=2.4, 95% CI=1.2 4.5) and smoking persistence (OR=4.0, 95% CI=1.5 10.3) than those who have CYP2A6*4C genotypes. CYP2A6 drug nicotine 19415821 Moreover, the best model involved a gene gene interaction between MAOA and CYP2A6 was characterized by the multifactor dimensionality reduction method (64.11% accuracy, P<0.001), and indicated that carriers of the combined 1460 T/O genotype for MAOA EcoRV and CYP2A6*1/CYP2A6*1 genotypes were at higher risk of smoking (OR=15.4, 95% CI=4.5 52.5). CYP2A6 drug nicotine 19415821 These findings suggested a substantial influence of CYP2A6 polymorphism as well as the interaction with MAOA resulting in risk modulation on smoking behavior in Chinese male population. CYP2A6 drug nicotine 19279561 Association of nicotine metabolite ratio and CYP2A6 genotype with smoking cessation treatment in African American light smokers. CYP2A6 drug nicotine 19279561 Cytochrome P450 2A6 (CYP2A6) is the main nicotine (NIC) metabolizing enzyme in humans. CYP2A6 drug nicotine 19279561 We investigated the relationships between CYP2A6 genotype, baseline plasma trans 3' hydroxycotinine/cotinine (3HC/COT) (a phenotypic marker of CYP2A6 activity), and smoking behavior in African American light smokers. CYP2A6 addiction dependence 19279561 Cigarette consumption, age of initiation, and dependence scores did not differ among 3HC/COT quartiles or CYP2A6 genotype groups. CYP2A6 drug nicotine 19279561 The determination of the 3HC/COT ratio, and possibly CYP2A6 genotype, may be useful in the future for personalizing the choice of smoking cessation treatment in African American light smokers. CYP2A6 drug nicotine 19251795 Recently, it has been shown that genetic variants in the dopaminergic system, opioid receptors, the bupropion metabolising enzyme CYP2B6 and the nicotine metabolising enzyme CYP2A6 may play an important role in predicting smoking cessation responses to nicotine replacement therapy and bupropion treatment. CYP2A6 drug opioid 19251795 Recently, it has been shown that genetic variants in the dopaminergic system, opioid receptors, the bupropion metabolising enzyme CYP2B6 and the nicotine metabolising enzyme CYP2A6 may play an important role in predicting smoking cessation responses to nicotine replacement therapy and bupropion treatment. CYP2A6 drug nicotine 19184652 Genetic studies have demonstrated that polymorphisms in CYP2A6, the primary enzyme responsible for nicotine breakdown, make a sizable contribution to the wide range of nicotine metabolic capacity observed in humans. CYP2A6 drug nicotine 19184652 Thus, special attention will be given to CYP2A6, because slower nicotine metabolism requires less frequent self administration, and accordingly influences smoking behaviors. CYP2A6 drug nicotine 19184645 Nicotine is metabolized primarily by the liver enzymes CYP2A6, UDPglucuronosyltransferase (UGT), and flavin containing monooxygenase (FMO). CYP2A6 drug nicotine 19169923 Nicotine metabolism is mediated primarily by cytochrome P450 2A6 (CYP2A6). CYP2A6 drug nicotine 19169923 Genetic variation in the CYP2A6 gene has been linked with several smoking behavior phenotypes. CYP2A6 drug nicotine 19169923 Individuals who carry null or reduced activity alleles for CYP2A6 smoke fewer cigarettes per day, are less dependent on nicotine, and may have an easier time quitting smoking. CYP2A6 drug nicotine 19169923 A phenotypic measure of CYP2A6 enzyme activity, defined as the ratio of the nicotine metabolites 3'hydroxycotinine/cotinine, also predicts successful quitting with the transdermal nicotine patch, and counseling alone. CYP2A6 drug nicotine 19169923 Inhibition of the CYP2A6 enzyme to slow nicotine metabolism is a promising approach to increase nicotine availability and potentially reduce harm from tobacco smoking.

CYP2A6 drug nicotine 19018727 The CYP2A6 gene is highly polymorphic and CYP2A6 alleles coding for enzymes with altered expression or metabolic capacity produce alterations in nicotine metabolism in vivo and seem to influence smoking behavior. CYP2A6 drug nicotine 19018727 However, to date only a few and inconclusive studies have addressed the risk that a given CYP2A6 polymorphism presents for the development of tobacco related tumors. CYP2A6 drug nicotine 19018727 Finally, the interaction between polymorphisms of genes that code for CYP2A6, CYP2A13 and other potent carcinogen metabolizing CYP enzymes may help to determine individuals that are at higher risk of developing tumors associated with tobacco consumption. CYP2A6 drug nicotine 18976031 Genetic polymorphism of CYP2A6 gene is a major causal factor in the large interindividual differences in nicotine metabolism. CYP2A6 drug nicotine 18666753 The idea that the liver enzyme cytochrome P450 2A6 (CYP2A6), known also as nicotine C oxidase, is one of the determinants of smoking addiction and smoking behavior is primarily based on its role in nicotine metabolism and disposition.

CYP2A6 addiction dependence 18666753 The results of studies linking the CYP2A6 genetic polymorphism with smoking dependence and smoking behavior however remain controversial. CYP2A6 drug nicotine 18666753 In the present review, we summarize research findings on biological significance of CYP2A6 and gene polymorphisms together with a discussion on CYP2A6 inhibitors that hold the promise of uses in smoking cessation. CYP2A6 drug nicotine 18666753 In addition, we provide the phenotype/genotype information derived from our systematic investigation on the relationship between CYP2A6 genotypes, smoking habits and coumarin metabolism phenotypes in a group of 393 normal adults (197 women and 196 men), 16 to 60 years of age, whose exposure to cadmium and lead were also determined, enabling us to assess the CYP2A6 phenotypic variability associated with CYP2A6 genotypes and environmental exposure. CYP2A6 drug nicotine 18666753 The results indicate that the phenotype of CYP2A6 enzyme in liver is an outcome of interactions between the CYP2A6 gene, cadmium, nicotine and possibly its metabolites.

CYP2A6 drug nicotine 18041664 Smoking behavior and related cancers: the role of CYP2A6 polymorphisms. CYP2A6 drug nicotine 18041664 The absorbed nicotine is rapidly and extensively metabolized to inactive cotinine by CYP2A6 in human livers, which has a major impact on nicotine clearance. CYP2A6 drug nicotine 18041664 Progress has been made in understanding the relationship between the inter individual variability in nicotine metabolism and genetic polymorphisms of CYP2A6. CYP2A6 drug nicotine 18041664 Recent findings have increased our knowledge concerning ethnic differences in the allele frequencies of the CYP2A6 variants, nicotine metabolism, and cancer risk. CYP2A6 drug nicotine 18041664 In this review, the potential associations between the CYP2A6 polymorphisms and smoking behavior or the risk of cancer are also discussed. CYP2A6 drug nicotine 18004205 Gene gene interactions between CYP2B6 and CYP2A6 in nicotine metabolism. CYP2A6 drug nicotine 18004205 CYP2A6 is the major enzyme involved in nicotine metabolism, yet large interindividual variations in the rate of nicotine metabolism exist within groups of individuals having the same CYP2A6 genotype. CYP2A6 drug nicotine 18004205 We investigated the influence of genetic variation in another potential nicotine metabolizing enzyme, CYP2B6, and its interaction with CYP2A6, on the metabolism of nicotine. CYP2A6 drug nicotine 18004205 We observed that the CYP2B6*6 haplotype (defined as having both Q172 H and K262R variants) was associated with faster nicotine and cotinine clearance, and that such associations were more prominent among individuals having decreased activity CYP2A6 genotypes. CYP2A6 drug nicotine 18004205 Statistically significant interactions between CYP2B6 and CYP2A6 genotypes were observed (P<0.003 for nicotine clearance and P<0.002 for cotinine clearance). CYP2A6 drug nicotine 18004205 Our results indicate that CYP2B6 genetic variation is associated with the metabolism of nicotine and cotinine among individuals with decreased CYP2A6 activity.

CYP2A6 drug nicotine 17934923 As a result, the frequency of the CYP2A6*4C gene (enzyme activity deficit) was significantly (p<0.05) higher among nonsmokers than smokers, and the Openness score by NEO FFI was higher among smokers than nonsmokers. CYP2A6 drug nicotine 17934923 We conclude that the CYP2A6*4C gene and the Openness personality trait may affect the development of the smoking behavior of youth.

CYP2A6 drug nicotine 17454707 An association of CYP2A6 genotype and smoking topography. CYP2A6 drug nicotine 17454707 Nicotine is metabolized into biologically inactive cotinine primarily by the cytochrome P450 enzyme CYP2A6. CYP2A6 drug nicotine 17454707 CYP2A6 also is involved in the metabolic activation of tobacco specific procarcinogenic nitrosamines, such as 4 (methyl nitrosamino) 1 (3 pyridyl) 1 butanone (NNK) and 4 (methyl nitrosamino) 1 (3 pyridyl) 1 butanol (NNAL). CYP2A6 drug nicotine 17454707 The present study investigated the association of CYP2A6 genotype with smoking topography, a quantifiable measure of smoking behavior, in a sample of treatment seeking smokers prior to treatment. CYP2A6 addiction relapse 17454707 The present study investigated the association of CYP2A6 genotype with smoking topography, a quantifiable measure of smoking behavior, in a sample of treatment seeking smokers prior to treatment. CYP2A6 drug nicotine 17454707 Smokers having CYP2A6 variants resulting in low activity metabolize nicotine more slowly, and convert procarcinogen nitrosamines to carcinogens more slowly, than do normal metabolizers. CYP2A6 drug nicotine 17372541 Some variants of the cytochrome P450 seem to be more frequent among dependent smokers than controls or ever smokers (CYP2A6) and heavier smokers (CYP2D6). CYP2A6 drug nicotine 17130279 The role of CYP2A6 in the emergence of nicotine dependence in adolescents. CYP2A6 addiction dependence 17130279 The role of CYP2A6 in the emergence of nicotine dependence in adolescents. CYP2A6 drug nicotine 17130279 Latent growth curve modeling indicated that normal metabolizers (individuals with no detected CYP2A6 variants) progressed in nicotine dependence at a faster rate and that these increases in nicotine dependence leveled off more slowly compared with slower metabolizers (individuals with CYP2A6 variants).

CYP2A6 drug nicotine 17037346 [The relationship between smoking behavior in young people and CYP2A6 gene polymorphisms, between them and personality traits assessed by NEO FFI]. CYP2A6 drug nicotine 17037346 Samples were taken from young students of which 87 were smokers and 142 were non smokers and we tried to clarify the relationship between the nicotine metabolizing ability (CYP2A6), personality, and smoking behavior. CYP2A6 drug nicotine 17037346 As a result, the frequency of the CYP2A6*4C gene was significantly higher among non smokers than smokers, and the Openness score by NEO FFI was higher among smokers than non smokers. CYP2A6 drug nicotine 17037346 We concluded that the CYP2A6*4C gene and the Openness personality trait may be a cause of smoking among the young smokers. CYP2A6 drug nicotine 17037346 Therefore, there is a possibility that smoking behavior in youths may be affected not only by the CYP2A6 gene but also by the Openness personality trait. CYP2A6 drug nicotine 17021260 Studies were undertaken to examine whether methoxsalen (9 methoxyfuro[3,2 g][1]benzopyran 7 one), a specific and relatively selective inhibitor of human CYP2A6, inhibited CYP2A5 mediated nicotine metabolism in vitro. CYP2A6 drug nicotine 17015050 However, known alleles of CYP2A6 associated with fast or slow metabolism are relatively uncommon, and there remains considerable variation in metabolic activity among those with presumed wild type CYP2A6 alleles, suggesting that other genetic or environmental factors also influence the rate of nicotine metabolism. CYP2A6 drug nicotine 17015050 The ratio of the nicotine metabolite trans 3' hydroxycotinine to cotinine in plasma was used as an index of CYP2A6 activity and thus as a marker of the rate of nicotine metabolism. CYP2A6 drug nicotine 17015050 The nicotine metabolite ratio was associated with sex (P < .0001), CYP2A6 genotype (*1B, *2, *4, *9, and *12) (P < .0001), CYP2B6 haplotype (*4 dominant) (P = .02), plasma nicotine concentration (P < .0001), and age (P = .02) but was not associated with dependence score (P > .20). CYP2A6 addiction dependence 17015050 The nicotine metabolite ratio was associated with sex (P < .0001), CYP2A6 genotype (*1B, *2, *4, *9, and *12) (P < .0001), CYP2B6 haplotype (*4 dominant) (P = .02), plasma nicotine concentration (P < .0001), and age (P = .02) but was not associated with dependence score (P > .20). CYP2A6 drug nicotine 17015050 In this cohort the rate of nicotine metabolism is related to age, sex, CYP2A6 genotype, and CYP2B6 genotype and may affect the level of tobacco consumption. CYP2A6 drug nicotine 16952495 Comprehensive evaluation of variability in nicotine metabolism and CYP2A6 polymorphic alleles in four ethnic populations. CYP2A6 drug nicotine 16952495 However, there are few data on the ethnic influences of the CYP2A6 nicotine metabolism relationship, particularly with regard to black subjects. CYP2A6 drug nicotine 16952495 We determined the nicotine metabolism and CYP2A6 genotype in 176 white subjects and 160 black subjects, comparing them with our previous data from 209 Korean subjects and 92 Japanese subjects. CYP2A6 drug nicotine 16952495 These CYP2A6 alleles were associated with reduced nicotine metabolism. CYP2A6 drug nicotine 16952495 This comprehensive study of 4 populations extends our understanding of nicotine metabolism and the impact of genetic polymorphisms of the CYP2A6 gene. CYP2A6 drug nicotine 16872570 Within subject variation of the salivary 3HC/COT ratio in regular daily smokers: prospects for estimating CYP2A6 enzyme activity in large scale surveys of nicotine metabolic rate. CYP2A6 drug nicotine 16872570 The 3HC/COT ratio measured in the saliva of smokers is highly correlated with the intrinsic hepatic clearance of nicotine and, therefore, may be a useful non invasive marker of CYP2A6 activity and metabolic rate of nicotine. CYP2A6 drug nicotine 16872570 These findings should be useful for designing large scale population surveys to assess the variation in the metabolic rate of nicotine (via CYP2A6) in smokers. CYP2A6 drug opioid 16785264 Candidate genes include those involved in central mechanisms (such as genes encoding the nicotinic acetylcholine receptors, dopamine receptors, dopamine transporters and opioid receptors) and peripheral mechanisms (such as genes encoding the drug metabolizing enzymes CYP2A6 and CYP2B6).

CYP2A6 drug nicotine 16272956 Mutations in CYP2A6 slow metabolism of nicotine to cotinine. CYP2A6 drug nicotine 16272956 1518 subjects from the Ten Towns Heart Health Study were genotyped for CYP2A6 alleles *1A, *1B, *2, *4, *5, *9 and *12 to classify predicted nicotine metabolism rate. CYP2A6 drug nicotine 16272956 At age 18, haploinsufficiency (HI) for CYP2A6 was associated with a higher odds of being a current smoker compared with the *1B carriers (WT1B) (OR = 2.23 (1.16, 4.27) for current versus ex); *1A homozygotes (WT1A) were also at slightly higher risk (OR = 1.44 (1.01, 2.06)).

CYP2A6 drug nicotine 16141602 A major pathway of nicotine metabolism is C oxidation to cotinine, which is catalyzed by CYP2A6 in human livers. CYP2A6 drug nicotine 16141602 Since the genetic polymorphisms of the CYP2A6 gene have a major impact on nicotine clearance, its relationships with smoking behavior or the risk of lung cancer have been suggested. CYP2A6 drug nicotine 15735610 Our objective was to evaluate the effect of the phase of the menstrual cycle on the activity of CYP2A6 and the cardiovascular effects of nicotine.

CYP2A6 drug nicotine 15735609 Some, but not all, studies suggest that genetic variation in CYP2A6 may play a role in smoking. CYP2A6 drug nicotine 15735609 We review some of the recent findings on the influence of CYP2A6 genetic polymorphisms on nicotine kinetics, smoking behaviors, and how the gene appears to exert differential effects during various stages of smoking (eg, initiation, conversion to dependence, amount smoked during dependence, and quitting).

CYP2A6 drug nicotine 15534625 These data suggest that the CYP2A6(*)1B is associated with smoking dependence in white and intermediate, but not black Brazilians. CYP2A6 addiction dependence 15534625 These data suggest that the CYP2A6(*)1B is associated with smoking dependence in white and intermediate, but not black Brazilians.

CYP2A6 drug nicotine 15475735 Genetically variable CYP2A6 is the primary enzyme that inactivates nicotine to cotinine. CYP2A6 drug nicotine 15475735 Adult Caucasian non smokers (n = 224) (1 99 cigarettes/lifetime) and smokers (n = 375) (> or = 100 cigarettes/lifetime) were assessed for demographics, tobacco/drug use history and DSM IV dependence and genotyped for CYP2A6 alleles associated with decreased nicotine metabolism (CYP2A6*2, CYP2A6*4, CYP2A6*9, CYP2A6*12). CYP2A6 addiction dependence 15475735 Adult Caucasian non smokers (n = 224) (1 99 cigarettes/lifetime) and smokers (n = 375) (> or = 100 cigarettes/lifetime) were assessed for demographics, tobacco/drug use history and DSM IV dependence and genotyped for CYP2A6 alleles associated with decreased nicotine metabolism (CYP2A6*2, CYP2A6*4, CYP2A6*9, CYP2A6*12). CYP2A6 drug nicotine 15229465 Our objective was to evaluate the use of oral nicotine with measurement of the trans 3' hydroxycotinine (3HC)/cotinine (COT) metabolite ratio as a noninvasive probe of CYP2A6 activity. CYP2A6 drug nicotine 15229465 The ratio appears to be a useful noninvasive marker of the rate of nicotine metabolism (which is important in studying nicotine addiction and smoking behavior), as well as a general marker of CYP2A6 activity (which is important in studying drug and toxin metabolism).

CYP2A6 drug nicotine 15203795 A meta analytic review of the CYP2A6 genotype and smoking behavior. CYP2A6 drug nicotine 15203795 Individuals who carry variant alleles of the CYP2A6 gene are poor metabolizers of nicotine and are believed to be more sensitive to nicotine's aversive effects than those with normal alleles. CYP2A6 addiction aversion 15203795 Individuals who carry variant alleles of the CYP2A6 gene are poor metabolizers of nicotine and are believed to be more sensitive to nicotine's aversive effects than those with normal alleles. CYP2A6 drug nicotine 15203795 Although early studies found an association between variant CYP2A6 alleles and smoking behavior, more recent studies have not. CYP2A6 drug nicotine 15203795 A literature search produced 11 studies providing information on CYP2A6 genotyping in smokers or nonsmoking control subjects. CYP2A6 drug nicotine 15203795 Participants were classified as smokers (ever smokers or current smokers) or nonsmokers (former or never smokers), and as carrying normal CYP2A6 genes or one or more variant alleles. CYP2A6 drug nicotine 15203795 This analysis failed to find any empirical evidence of a relationship between variant CYP2A6 alleles and smoking status (n=4091) or cigarette consumption (n=1537). CYP2A6 drug nicotine 15203795 Although these results suggest the CYP2A6 gene is not associated with smoking behavior, the use of broad smoking status classifications (e.g., ever vs. never smoking), which fail to account for the complex nature of gene expression (e.g., gene gene interactions), may have obscured the relatively modest genetic influences that might have been present. CYP2A6 drug nicotine 15203795 What role, if any, the CYP2A6 gene plays in smoking behavior will be understood only if future research addresses these methodological concerns. CYP2A6 drug nicotine 14668073 We studied the effect of inhibiting CYP2A6 on smoking behavior and metabolism of the procarcinogen NNK. CYP2A6 drug nicotine 14668073 In study 1, abstinent smokers (n=7) received methoxsalen (a potent CYP2A6 inhibitor), 30 50 mg orally, one half hour before three subcutaneous nicotine injections (31 microg/kg) were given at hourly intervals. CYP2A6 drug nicotine 14668073 Thus, treatment with the CYP2A6 inhibitor methoxsalen in vivo increases the routing of NNK to the inactive NNAL glucuronide and decreases smoking. CYP2A6 drug nicotine 14668073 CYP2A6 inhibition may have potential as an exposure reduction or cessation strategy in tobacco dependence.

CYP2A6 drug nicotine 12749606 Association of CYP2A6 gene deletion with cigarette smoking status in Japanese adults. CYP2A6 drug nicotine 12749606 Genetic variation of CYP2A6 is shown to alter nicotine metabolism. CYP2A6 drug nicotine 12749606 This study was developed to investigate the genetic influence of the whole deletion allele of CYP2A6 on active and passive smoking behavior. CYP2A6 drug nicotine 12749606 Genetic influence of CYP2A6 polymorphism on smoking behavior was evaluated using the Mantel extension test. CYP2A6 drug nicotine 12749606 Furthermore, CYP2A6 genotypes were correlated neither with the number of cigarettes smoked per day nor with the age at starting smoking (p = 0.364 and 0.880, respectively). CYP2A6 drug nicotine 12749606 Among never smokers, CYP2A6 genotypes were not correlated with exposure to passive smoking at home or in the workplace (p = 0.623 and 0.484, respectively). CYP2A6 drug nicotine 12749606 Despite the possible protection against active smoking behavior in subjects homozygous for the deletion allele, the CYP2A6 polymorphism has only a limited impact on public health because no protective effect was found in heterozygous subjects. CYP2A6 drug nicotine 11805739 Genetic variation in CYP2A6 mediated nicotine metabolism alters smoking behavior. CYP2A6 drug nicotine 11805739 The genetically polymorphic CYP2A6 enzyme is responsible for the majority of the metabolic inactivation of nicotine to cotinine (12 14). CYP2A6 drug nicotine 11805739 CYP2A6 is genetically polymorphic, individuals carrying inactive CYP2A6 alleles have decreased nicotine metabolism, are less likely to become smokers and if they do, they smoke fewer cigarettes per day (13,18,19). CYP2A6 drug nicotine 11805739 A duplication variant in the CYP2A6 gene locus has been identified which increases nicotine inactivation and increases smoking (19). CYP2A6 drug nicotine 11805739 CYP2A6 can also activate tobacco smoke procarcinogens (e.g. CYP2A6 drug nicotine 11805739 Kinetic studies in humans indicated that selective CYP2A6 inhibitors decrease the metabolic removal of nicotine. CYP2A6 drug nicotine 11805739 It was also shown that inhibiting CYP2A6 in vivo (phenocopying, or mimicking the genetic defect) in smokers results in decreased smoking, making nicotine orally bioavailable, and the rerouting of procarcinogens to detoxifying pathways (20 22). CYP2A6 drug nicotine 11768189 CYP2A6 is the enzyme responsible for the majority of the inactivation of nicotine in humans. CYP2A6 drug nicotine 11768189 This paper outlines how genetic variation in the CYP2A6 gene may protect individuals from becoming nicotine dependent smokers, and if dependent, how impairment of the CYP2A6 gene function decreases the number of cigarettes consumed by smokers (Pianezza M, Sellers EM, Tyndale RF. CYP2A6 drug nicotine 11768189 We also discuss recent findings which suggest that mimicking this gene defect by inhibiting CYP2A6 decreases nicotine metabolism and smoking. CYP2A6 drug nicotine 11768189 Further research is needed in order to improve our understanding of how genetic variation in CYP2A6 alters the risk for nicotine dependence and lowers nicotine consumption. CYP2A6 addiction dependence 11768189 Further research is needed in order to improve our understanding of how genetic variation in CYP2A6 alters the risk for nicotine dependence and lowers nicotine consumption. CYP2A6 drug nicotine 11768189 This includes a better understanding of how the genetic variants alter nicotine metabolism in vivo in males and females as well as the role of CYP2A6 genetic variation in risk for tobacco related cancers. CYP2A6 drug nicotine 11259349 Variable CYP2A6 mediated nicotine metabolism alters smoking behavior and risk. CYP2A6 drug nicotine 11259349 In humans, 70 to 80% of nicotine is metabolized to the inactive metabolite cotinine by the enzyme CYP2A6. CYP2A6 drug nicotine 11259349 CYP2A6 can also activate tobacco smoke procarcinogens [e.g., NNK, 4 (methylnitrosamino) 1 (3 pyridyl) 1 butanone]. CYP2A6 drug nicotine 11259349 In initial studies we found that there was an under representation of individuals carrying defective CYP2A6 alleles in a tobacco dependent population, and that among smokers, those with deficient nicotine metabolism smoked fewer cigarettes. CYP2A6 drug nicotine 11259349 We have since reproduced this data in a prospective smoking study (400 male and female, heavy and light smokers) examining the role of the CYP2A6 genotype on carbon monoxide levels, plasma and urine nicotine and cotinine levels, and cigarette counts. CYP2A6 drug nicotine 11259349 We have also recently identified deletion and duplication variants in the CYP2A6 gene locus and have examined their impact on smoking. CYP2A6 drug nicotine 11259349 Both kinetic and behavioral experiments in human smokers demonstrated that inhibiting CYP2A6 in vivo decreased nicotine metabolism and smoking behavior. CYP2A6 drug nicotine 11207029 Cytochrome P450 2A6 (CYP2A6) is involved in the C oxidation of nicotine and in the metabolic activation of tobacco nitrosamines.

CYP2A6 addiction dependence 11207029 Recent data have suggested that CYP2A6 genetic polymorphisms might play a role in tobacco dependence and consumption as well as in lung cancer risk. CYP2A6 drug nicotine 11207029 In this Caucasian population, we found neither a relation between genetically impaired nicotine metabolism and cigarette consumption, nor any modification of lung cancer risk related to the presence of defective CYP2A6 alleles (odds ratio = 1.1, 95% confidence interval = 0.7 1.9).

CYP2A6 addiction dependence 10945314 Hepatic CYP2A6 accounts for nicotine's low systemic bioavailability, precluding oral nicotine replacement to treat dependence. CYP2A6 drug nicotine 10945314 We sought to determine whether CYP2A6 inhibition via oral methoxsalen decreases nicotine clearance, increases nicotine bioavailability, and decreases smoking. CYP2A6 drug nicotine 10945314 Placebo plus nicotine 4 mg orally increased the mean 3 hour plasma nicotine level by 4 ng/mL over residual baseline nicotine level, whereas methoxsalen 10 or 30 mg plus nicotine increased it by 9 ng/mL (P<.01), demonstrating in vivo inhibition of CYP2A6 nicotine metabolism. CYP2A6 drug nicotine 10945314 CYP2A6 inhibitors may have an important role in smoking cessation and tobacco exposure reduction.

TRPV1 drug alcohol 19705551 The vanilloid receptor TRPV1 is activated by ethanol and this may be important for some of the central and peripheral actions of ethanol. TRPV1 drug alcohol 19705551 To determine if this receptor has a role in ethanol mediated behaviors, we studied null mutant mice in which the Trpv1 gene was deleted. TRPV1 drug alcohol 19705551 Two behavioral phenotypes (decreased sensitivity to ethanol induced sedation and faster recovery from ethanol induced motor incoordination) seen in null mutant mice were reproduced in wild type mice by injection of a TRPV1 antagonist, capsazepine (10 mg/kg).

TRPV1 addiction sensitization 19473241 TRPV1 controls acid and heat induced calcitonin gene related peptide release and sensitization by bradykinin in the isolated mouse trachea.

TRPV1 drug cannabinoid 19064314 The endocannabinoid anandamide is a possible agonist at the Transient Receptor Potential Vanilloid Type 1 (TRPV1) channel, in addition to its agonist activity at cannabinoid type 1 (CB1) receptor. TRPV1 addiction aversion 19064314 Altogether, our data suggest that, while CB1 receptors seem to inhibit aversive responses in the dlPAG, TRPV1 could facilitate them. TRPV1 drug cannabinoid 19015836 Since anandamide is a ligand for not only cannabinoid receptors but also transient receptor potential vanilloid 1 (TRPV1) receptors, and as recently suggested, peroxisome proliferator activated nuclear receptor alpha (PPARalpha), we also determined whether anandamide's effects in this task were mediated by each of these receptors.

TRPV1 drug alcohol 18839303 Ethanol is a known oral trigeminal stimulant and recent data indicate that these effects are mediated in part by transient receptor potential channel vanilloid receptor 1 (TRPV1). TRPV1 drug alcohol 18839303 Here, we compared orosensory responding to ethanol in TRPV1 deficient and wild type mice in a brief access paradigm that assesses orosensory influences by measuring immediate licking responses to small stimulus volumes. TRPV1 drug alcohol 18839303 TRPV1( / ) and control mice were tested with six concentrations of ethanol (3, 5, 10, 15, 25, 40%), capsaicin (0.003, 0.01, 0.03, 0.1, 0.3, 1 mM), sucrose (0.003, 0.01, 0.03, 0.1, 0.3, 1 M), and quinine (0.01, 0.03, 0.1, 0.3, 1, 3 mM) and psychophysical concentration response functions were generated for each genotype and stimulus. TRPV1 drug alcohol 18839303 TRPV1 knockouts displayed reduced oral avoidance responses to ethanol regardless of concentration, insensitivity to capsaicin, and little to no difference in sweet or bitter taste responding relative to wild type mice. TRPV1 drug alcohol 18839303 These data indicate that the TRPV1 channel plays a role in orosensory mediated ethanol avoidance, but that other receptor mechanisms likely also contribute to aversive oral responses to alcohol. TRPV1 addiction aversion 18839303 These data indicate that the TRPV1 channel plays a role in orosensory mediated ethanol avoidance, but that other receptor mechanisms likely also contribute to aversive oral responses to alcohol. TRPV1 addiction reward 18828909 Characterization of mouse orofacial pain and the effects of lesioning TRPV1 expressing neurons on operant behavior. TRPV1 addiction reward 18828909 In the current study, we used an operant model based on a reward conflict paradigm to assess nociceptive responses in three strains of mice (SKH1 Hrhr, C57BL/6J, TRPV1 knockout). TRPV1 addiction reward 18828909 Additionally, we evaluated the effects on operant behaviors of mice manipulated genetically (e.g., TRPV1 k.o.) TRPV1 addiction reward 18828909 As the temperature of the thermal stimulus became noxiously hot, reward licking events in SKH1 Hrhr and C57BL/6J mice declined while licking events in TRPV1 k.o. TRPV1 addiction sensitization 18755744 TRPV1 receptors on unmyelinated C fibres mediate colitis induced sensitization of pelvic afferent nerve fibres in rats. TRPV1 addiction sensitization 18755744 The aim of the current study was to investigate the role of transient receptor potential of the vanilloid type 1 (TRPV1) receptors in the pathophysiology of colitis induced pelvic afferent nerve sensitization. TRPV1 addiction sensitization 18755744 TRPV1 signalling mediates the colitis induced sensitization of pelvic afferent C fibres to CRD, while Adelta fibres are neither sensitized by colitis nor affected by TRPV1 inhibition. TRPV1 drug opioid 18579164 Removing TRPV1 expressing primary afferent neurons potentiates the spinal analgesic effect of delta opioid agonists on mechano nociception. TRPV1 drug opioid 18579164 In this study, we determined the role of delta opioid receptors expressed on TRPV1 sensory neurons in the antinociceptive effect of the delta opioid receptor agonists [D Pen(2),D Pen(5)] enkephalin and [D Ala(2),Glu(4)] deltorphin. TRPV1 drug opioid 18579164 In RTX treated rats, the delta opioid receptor on TRPV1 immunoreactive dorsal root ganglion neurons and afferent terminals in the spinal cord was diminished. TRPV1 drug opioid 18579164 These findings indicate that loss of TRPV1 expressing afferent neurons leads to a substantial reduction in presynaptic delta opioid receptors in the spinal dorsal horn. TRPV1 drug opioid 18579164 However, the effect of delta opioid agonists on mechano nociception is paradoxically potentiated in the absence of TRPV1 expressing sensory neurons. TRPV1 addiction sensitization 18482991 Sensitization of TRPV1 responses by cAMP dependent PKA crucially contributes to the development of inflammatory hyperalgesia. TRPV1 drug opioid 18482991 Using HEK cells stably expressing TRPV1 and the mu opioid receptor, we demonstrated that treatment with the adenylate cyclase activator forskolin significantly increased the multimeric TRPV1 species. TRPV1 drug opioid 18482991 Pretreatment with the mu opioid receptor agonist morphine reversed this increased TRPV1 multimerization. TRPV1 drug opioid 18482991 Treatment with forskolin also caused an increase in TRPV1 expression on the plasma membrane not resulting from increased TRPV1 expression, and this rapid TRPV1 translocation was inhibited by treatment with morphine. TRPV1 addiction sensitization 18065157 The sensitization to heat appears unusually resistant against pharmacological interventions and does not involve TRPV1.

TRPV1 drug opioid 17239544 Deletion of transient receptor potential vanilloid type 1 (TRPV1) expressing afferent neurons reduces presynaptic mu opioid receptors but paradoxically potentiates the analgesic efficacy of mu opioid agonists. TRPV1 drug opioid 17239544 In this study, we determined if removal of TRPV1 expressing afferent neurons by resiniferatoxin (RTX), an ultrapotent capsaicin analog, influences the development of opioid analgesic tolerance. TRPV1 drug opioid 17239544 These findings suggest that loss of TRPV1 expressing sensory neurons attenuates the development of morphine analgesic tolerance possibly by reducing mu opioid receptor desensitization through protein kinase Cgamma in the spinal cord. TRPV1 drug opioid 17239544 These data also suggest that the function of presynaptic mu opioid receptors on TRPV1 expressing sensory neurons is particularly sensitive to down regulation by mu opioid agonists during opioid tolerance development. TRPV1 addiction withdrawal 16962719 Intraplantar capsaicin produced dose related SMH (enhanced paw withdrawal response to von Frey monofilament stimulation at an area away from injection site) that lasted for over 4 h. While pretreatment with a potent selective transient receptor potential vanilloid receptor 1 (TRPV1) antagonist A 425619 (1 isoquinolin 5 yl 3 (4 trifluoromethyl benzyl) urea) prevented development of acute nocifensive (flinching) behavior immediately following capsaicin injection (ED(50)=4.9 mg/kg), the compound failed to attenuate the SMH when administered 2 h following capsaicin (10 microg/10 microl). TRPV1 drug opioid 16467418 Loss of TRPV1 expressing sensory neurons reduces spinal mu opioid receptors but paradoxically potentiates opioid analgesia. TRPV1 drug opioid 16467418 In this study, we determined how loss of TRPV1 expressing sensory neurons alters the antinociceptive effect of mu opioids and mu opioid receptors in the spinal cord. TRPV1 drug opioid 16467418 However, RTX treatment did not affect the dorsal horn neurons labeled with both TRPV1 and mu opioid receptor immunoreactivity. TRPV1 drug opioid 16467418 This study provides novel information that loss of TRPV1 afferent neurons eliminates presynaptic mu opioid receptors present on TRPV1 expressing afferent neurons but paradoxically potentiates the analgesic effect of mu opioid agonists. TRPV1 drug opioid 16467418 Mechano nociception, transmitted through non TRPV1 sensory neurons, is subject to potent modulation by mu opioid agonists. TRPV1 drug opioid 15288402 Finally, TRPV1 does not appear to be under tonic opioid receptor control since the opioid antagonist naloxone does not change CAP induced excitation and does not effect OCT induced inhibition of CAP responses. TRPV1 drug opioid 15157710 Loci in the vanilloid receptor subtype 1 gene (TRPV1), delta opioid receptor subtype 1 gene (OPRD1) and catechol O methyltransferase gene (COMT) were genotyped using 5' nuclease assays. TRPV1 addiction withdrawal 15157710 Female European Americans with the TRPV1 Val(585) Val allele and males with low harm avoidance showed longer cold withdrawal times based on the classification and regression tree (CART) analysis. TRPV1 drug alcohol 15128291 In addition, this mechanism links TRPV1 to intracellular signaling by various important endogenous as well as exogenous substances such as bradykinin, ethanol, nicotin and insulin. GRM2 drug alcohol 32599136 Our findings demonstrate that developmental alcohol exposure enhances alcohol intake during adolescence, which is associated with a decrease in the pCREB/CREB ratio in the hippocampus, prefrontal cortex and striatum, while the GluR1/GluR2 ratio showed a decrease in the hippocampus.

GRM2 drug alcohol 31233806 Loss of mGlu2 function has recently been associated with increased ethanol seeking and consumption, but the ability of alcohol to produce adaptations in mGlu2 function in the DLS has not been investigated. GRM2 addiction relapse 31233806 Loss of mGlu2 function has recently been associated with increased ethanol seeking and consumption, but the ability of alcohol to produce adaptations in mGlu2 function in the DLS has not been investigated. GRM2 drug alcohol 31233806 We exposed male C57Bl/6J mice to a 2 week chronic intermittent ethanol (CIE) paradigm followed by a brief withdrawal period, then used whole cell patch clamp recordings of glutamatergic transmission in the striatum to assess CIE effects on mGlu2 mediated synaptic plasticity. GRM2 addiction withdrawal 31233806 We exposed male C57Bl/6J mice to a 2 week chronic intermittent ethanol (CIE) paradigm followed by a brief withdrawal period, then used whole cell patch clamp recordings of glutamatergic transmission in the striatum to assess CIE effects on mGlu2 mediated synaptic plasticity. GRM2 drug alcohol 31233806 Interestingly, CIE induced impairment of mGlu2 LTD in the dorsolateral striatum is only observed when alcohol exposure occurs during adolescence. GRM2 drug alcohol 31233806 In contrast to the 2 week CIE paradigm, acute exposure of striatal slices to ethanol concentrations that mimic ethanol levels during CIE exposure fails to disrupt mGlu2 LTD. We did not observe a reduction of mGlu2 mRNA or protein levels following CIE exposure, suggesting that alcohol effects on mGlu2 occur at the functional level. GRM2 drug alcohol 31233806 Our findings contribute to growing evidence that adolescents are uniquely vulnerable to certain alcohol induced neuroadaptations, and identify enhancement of mGlu2 activity as a strategy to reverse the effects of adolescent alcohol exposure on DLS physiology.

GRM2 drug amphetamine 30240581 Chronic methamphetamine self administration dysregulates 5 HT2A and mGlu2 receptor expression in the rat prefrontal and perirhinal cortex: Comparison to chronic phencyclidine and MK 801. GRM2 drug amphetamine 30240581 Therefore, in the present study we examined the effects of chronic exposure to three different drugs known to produce persistent deficits in sensorimotor gating and cognition [meth, phencyclidine (PCP) and MK 801] on the expression of 5 HT2A and mGlu2 within the rat medial prefrontal cortex (mPFC), dorsal hippocampus (dHPC) and perirhinal cortex (PRh). GRM2 drug amphetamine 30240581 We found that despite different pharmacological mechanism of action, chronic meth, PCP, and MK 801 similarly dysregulated 5 HT2A and mGlu2, as indicated by an increase in the 5 HT2A/mGlu2 expression ratio in the mPFC (all three tested drugs), PRh (meth and PCP), and dHPC (MK 801 only). GRM2 drug amphetamine 30240581 In summary, these data suggest that a shift towards increased availability (and G protein coupling) of cortical 5 HT2A vs. mGlu2 receptors may represent a common neurobiological mechanism underlying the emergence of psychosis and cognitive deficits observed in subjects with meth use disorder and schizophrenia.

GRM2 drug amphetamine 29363229 Acupuncture inhibition of METH induced NAc temperature was prevented by pre treatment with a group II metabotropic glutamate receptors (mGluR2/3) antagonist EGLU into the NAc or mimicked by injection of an mGluR2/3 agonist DCG IV into the NAc. GRM2 drug amphetamine 29363229 These results suggest that acupuncture reduces extracellular DA release and metabolic neuronal activity in the NAc through activation of mGluR2/3 and suppresses METH induced affective states and locomotor behavior.

GRM2 addiction relapse 28988614 The present study employed radioligand binding and Western blot assays to study mGlu2/3R density, affinity and protein expression in selected rat brain areas after cocaine self administration, extinction training and cocaine induced reinstatement. GRM2 drug cocaine 28988614 Cocaine self administration and yoked cocaine delivery resulted in a significant increase in the mGlu2/3R density in the prefrontal cortex and the dorsal striatum, while 10 day extinction training provoked a reduction in the prefrontal cortex and the nucleus accumbens. GRM2 drug cocaine 28988614 Cocaine abstinence also enhanced an increase in the [3H]ligand binding to mGlu2/3R in the prefrontal cortex.

GRM2 drug amphetamine 28870523 Antagonism of mGlu2/3 receptors in the nucleus accumbens prevents oxytocin from reducing cued methamphetamine seeking in male and female rats. GRM2 addiction relapse 28870523 Antagonism of mGlu2/3 receptors in the nucleus accumbens prevents oxytocin from reducing cued methamphetamine seeking in male and female rats. GRM2 addiction relapse 28870523 Before reinstatement sessions, rats received LY341495, an mGluR2/3 antagonist, or its vehicle followed by a second infusion/injection of oxytocin or saline. GRM2 drug amphetamine 28870523 Overall, we report that oxytocin reduced responding to meth associated cues and blocking presynaptic mGluR2/3 reversed this effect. GRM2 drug opioid 28831734 A range of agonists or positive allosteric modulators (PAMs) for mostly Gi/o coupled receptors, including metabotropic glutamate2 (mGlu2), adenosine A1, or μ opioid receptors, suppress these effects of 5 HT2A receptor stimulation. GRM2 addiction relapse 28726801 However, glutamate release probability is negatively regulated by presynaptic mGluR2/3, and sucrose reinstatement was potentiated following mGluR2/3 blockade. GRM2 addiction relapse 28726801 Potentiated sucrose reinstatement by mGluR2/3 blockade was reversed by antagonizing mGluR5, but reinstated sucrose seeking in the absence of mGluR2/3 blockade was not affected by blocking mGluR5. GRM2 drug cocaine 28726801 In cocaine trained rodents mGluR5 stimulation reinstates drug seeking by activating nNOS, but activating mGluR5 did not promote reinstated sucrose seeking, nor was potentiated reinstatement after mGluR2/3 blockade reduced by blocking nNOS. GRM2 addiction relapse 28726801 In cocaine trained rodents mGluR5 stimulation reinstates drug seeking by activating nNOS, but activating mGluR5 did not promote reinstated sucrose seeking, nor was potentiated reinstatement after mGluR2/3 blockade reduced by blocking nNOS. GRM2 addiction relapse 28726801 These data indicate that dysregulated presynaptic mGluR2/3 signaling is a possible site of shared signaling in drug seeking and potentiated reinstated sucrose seeking, but that downregulated glutamate transport and subsequent activation of nNOS by synaptic glutamate spillover is not shared.

GRM2 addiction reward 27881347 The protein expressions of TH, NR2B and GLUR2 in the brain of zebrafish with CPP were detected with Western blotting. GRM2 drug amphetamine 27881347 Compared with the control group, zebrafish in methamphetamine group showed significant variations in the staying time and swimming distance in the drug box after conditioning (P<0.05) with obvious alterations of NR2B, TH and GLUR2 expressions in the brain (P<0.05).

GRM2 addiction relapse 27339394 Group II metabotropic glutamate receptors (mGluR2 and mGluR3) may control relapse of alcohol seeking, but previously available Group II agonists were unable to discriminate between mGluR2 and mGluR3. GRM2 drug alcohol 27339394 Here we use AZD8529, a novel positive allosteric mGluR2 modulator, to determine the role of this receptor for alcohol related behaviors in rats.

DRD4 drug nicotine 17387332 Smokers of European ancestry (n=720) who participated in a double blind, randomised, placebo controlled trial of transdermal nicotine replacement therapy, were genotyped for two functional polymorphisms (variable number of tandem repeats (VNTR) and a C to T transition at position 521 (C 521T)) in the dopamine D4 receptor gene (DRD4) gene. DRD4 drug nicotine 17387332 For the DRD4 VNTR models, the main effect of treatment was significant at both 12 week (P=0.001) and 26 week (P=0.006) follow ups, indicating an increased likelihood of successful cessation on active nicotine replacement therapy transdermal patch relative to placebo.

DRD4 addiction relapse 17309802 Effects of craving and DRD4 VNTR genotype on the relative value of alcohol: an initial human laboratory study. DRD4 addiction relapse 17309802 In addition, based on previous evidence of its role in the expression of craving, the influence of DRD4 VNTR genotype (DRD4 L vs. DRD4 S) was also examined. DRD4 drug alcohol 17309802 Thirty five heavy drinkers (54% male; 31% DRD4 L) were randomly assigned to receive either a craving induction (exposure to personally relevant alcohol cues) or a control induction (exposure to neutral cues), which was followed by an alcohol money choice task.

DRD4 addiction relapse 17309802 Factorial analyses including DRD4 VNTR genotype of did not suggest an influence on reactivity to the craving induction, although this analysis was substantially compromised by small cell sample sizes. DRD4 drug alcohol 17309802 Continuous analyses revealed that craving was significantly associated with the relative value of alcohol (p < .05) and possession of the DRD4 L allele further amplified this relationship (p < .001).

DRD4 drug alcohol 16945348 The aim of this study was to examine whether allelic variants of the dopamine D4 receptor gene (DRD4) are associated with alcohol use in adolescents and to determine the extent to which these links are mediated by NS. DRD4 drug alcohol 16945348 Male participants carrying the 7 repeat allele of DRD4 drank higher maximum amounts of alcohol per occasion and had greater lifetime rates of heavy drinking than male participants without this allele.

DRD4 addiction relapse 15900228 In 1997, study participants completed the Temperament and Character Inventory for the novelty seeking temperament trait, and a subsample (n=150) was genotyped for the DRD4 exon III polymorphism. DRD4 drug alcohol 15900228 For the participants with the father, but not the mother, reporting more frequent alcohol consumption or drunkenness in examinations 17 and/or 14 years before the novelty seeking assessment, an association between the short (two or five repeat) alleles of the DRD4 gene and extremely high novelty seeking scores was observed.

DRD4 addiction relapse 15900228 These results provide preliminary information on gene environment interaction on the temperament trait of novelty seeking and may partly explain the heterogeneity of findings concerning the association between DRD4 polymorphisms and novelty seeking. DRD4 addiction relapse 15876472 Results also suggest that the DRD4 VNTR polymorphism influences cue elicited craving for food, although the influence of the DRD4 may depend on the population under study.

DRD4 drug alcohol 12898574 For this study, homogeneous population consisting of 243 young alcohol and drug naive Koreans who were blood unrelated with a mean age (+/ SD) of 13.87 (+/ 0.30) years old was analyzed for the DRD4 and the DRD2 polymorphisms with their personality trait by Temperament and character inventory (TCI). DRD4 addiction relapse 12898574 The association between Novelty seeking (NS) score and DRD4 long alleles was only observed among the female subjects (t = 2.11, P = 0.037), but not in the male counter part. DRD4 addiction reward 12898574 These results, thus, confirmed the previous findings in which the long repeats of the DRD4 exon III polymorphism are related to NS personality trait, and also suggested that the DRD2 less frequent alleles were also associated with the reward dependent trait.

DRD4 addiction relapse 12888781 Olanzapine reduces craving for alcohol: a DRD4 VNTR polymorphism by pharmacotherapy interaction. DRD4 drug alcohol 12888781 Separate investigations have suggested that olanzapine, a D4 antagonist, decreases craving after a priming dose of alcohol and that the DRD4 variable number of tandem repeats (VNTR) polymorphism influences the expression of craving after a priming dose of alcohol.

DRD4 addiction relapse 12888781 The present study tested the hypothesis that olanzapine may be differentially effective at reducing cue elicited craving based on individual differences in DRD4 VNTR in a sample of heavy social drinkers. DRD4 drug alcohol 12888781 Participants who were homozygous or heterozygous for the 7 (or longer) repeat allele of the DRD4 VNTR were classified as DRD4 L, while the other participants were classified as DRD4 S. The findings indicated that olanzapine reduces craving for alcohol at baseline for both DRD4 S and DRD4 L individuals, but only reduces craving after exposure to alcohol cues and after a priming dose of alcohol for DRD4 L individuals. DRD4 addiction relapse 12888781 Participants who were homozygous or heterozygous for the 7 (or longer) repeat allele of the DRD4 VNTR were classified as DRD4 L, while the other participants were classified as DRD4 S.

Other genetic methods such as linkage analysis, allele sharing methods, association studies and analysis of inbred, transgenic and gene knockout rodents, have partially agreed in showing that the 5HT 1B serotonin receptor and the DRD1, DRD2 and DRD4 dopamine receptors, as well as the dopamine transporter DAT, play an important role in behaviors related to alcoholism and substance abuse. DRD4 drug alcohol 11347517 Two whole genome linkage studies have shown linkage to chromosomal regions that are in the proximity of the DRD4 dopamine receptor, the GABA receptor gene cluster and the alcohol dehydrogenase gene cluster.

DRD4 drug opioid 11054768 Association analysis of polymorphisms in the DRD4 gene and heroin abuse in Chinese subjects. DRD4 drug opioid 11054768 When we compared the heroin abuse group with controls, we found no significant difference between the patients and controls for either polymorphism in the DRD4 gene or their haplotypes. DRD4 drug opioid 11054768 We were also unable to replicate our earlier association between "long" DRD4 alleles and heroin abuse. DRD4 addiction relapse 11054768 The association we observed between inhalers and the DRD4 polymorphism is difficult to interpret, although it is possible that the association is explained by different levels of novelty seeking between the two subgroups. DRD4 drug alcohol 20575866 No significant association between the polymorphism at DRD4 and opiate or alcohol abuse was found. DRD4 addiction dependence 20575866 This study suggests that the DRD4 gene does not directly influence vulnerability to substance dependence, but that possession of the LL genotype significantly increases severity of dependence.

DRD4 drug alcohol 20575843 Using a classical case control approach we first compared DRD4 exon III VNTR frequencies between alcoholics and ethnically matched controls (sample I). DRD4 drug alcohol 20575843 The impact of the DRD4 exon III polymorphism on susceptibility to addictive behaviour putatively plays only a minor role in our sample of alcohol dependent patients, since we were not able to replicate our findings by the family based association approach.

DRD4 addiction relapse 10551544 The presence of the seven repeat allele of the VNTR in the exon 3 of the dopamine D4 receptor gene (DRD4) has been associated in healthy subjects to the personality trait of novelty seeking. DRD4 addiction relapse 10551544 The lack of association between novelty seeking and the DRD4 exon 3 polymorphism is further corroborated by the fact that the comorbid antisocial personality disorder is not associated to the presence of the seven repeat allele. DRD4 drug alcohol 10490712 To determine the role of genes in the chromosomal regions 11p15 and 4p12 in the development of alcohol dependence, a sample of alcoholics (n = 133) and normal controls (n = 89) were screened using polymorphisms in the dopamine D4 receptor (DRD4), tyrosine hydroxylase (TH), and GABA receptor beta1 (GABRbeta1) genes.

DRD4 drug alcohol 10490712 The allele distributions of the polymorphisms in the DRD4 and TH genes in alcoholics and normal controls were similar and their differences were not significant. DRD4 drug alcohol 10490712 Results with TH and DRD4 genes indicate that these two genes may not play major roles in the development of alcoholism. DRD4 addiction relapse 10379515 Recent reports suggest that DNA variants of the dopamine D4 receptor gene (DRD4) are associated with the personality trait of novelty seeking; however, others fail to replicate this finding.

DRD4 addiction relapse 10379515 We provide a critical analysis of genetic studies of DRD4 variants with novelty seeking, alcoholism, drug abuse, and attention deficit hyperactivity disorder. DRD4 addiction relapse 10379515 Evidence for the role of DRD4 in novelty seeking is inconclusive, with a number of methodological concerns. DRD4 drug alcohol 20575787 These results, together with those available in the literature for other ethnic groups, suggest a minor role, if any, of the DRD4 gene in the susceptibility to alcoholism.

DRD4 addiction relapse 26735123 The long form of the dopamine D4 receptor (D4DR) exon III repeat polymorphism has been linked in some but not all studies to impulsive, extravagant and novelty seeking personality traits that are prominent in affiliated behaviours such as attention deficit disorder and substance abuse.

DRD4 drug alcohol 9603615 The relationship of various dimensions of temperament, measured by the Tridimensional Personality Questionnaire (TPQ), to polymorphisms of the D2 dopamine receptor (DRD2) and D4 dopamine receptor (DRD4) genes was determined in 119 healthy Caucasian boys who had not yet begun to consume alcohol and other drugs of abuse. DRD4 addiction relapse 9603615 Boys with the DRD4 7 repeat (7R) allele also had a significantly higher Novelty Seeking score than those without this allele. DRD4 addiction relapse 9603615 However, the greatest difference in Novelty Seeking score was found when boys having all three minor DRD2 alleles and the DRD4 7R allele were contrasted to those without any of these alleles. DRD4 addiction dependence 9603615 Whereas subjects having all three minor DRD2 alleles had a significantly higher Reward Dependence 2 (Persistence) score than subjects without any of these alleles, no significant difference in this personality score was found between subjects with and without the DRD4 7R allele.

DRD4 addiction relapse 9603615 In conclusion, DRD2 and DRD4 polymorphisms individually associate with Novelty Seeking behavior. DRD4 addiction relapse 9433345 No association between novelty seeking and the type 4 dopamine receptor gene (DRD4) in two New Zealand samples. DRD4 addiction relapse 9433345 Two widely reported studies found significant associations between novelty seeking and the type 4 dopamine receptor gene (DRD4), although a more recent study did not. DRD4 addiction relapse 9433345 Novelty seeking and DRD4 were not statistically associated. DRD4 addiction relapse 9433345 In these samples, there was no suggestion that the DRD4 polymorphism contributed to individual differences in the behavioral trait of novelty seeking. DRD4 addiction relapse 9342196 Recently, a significant association between the seven repeat allele (DRD4*7R) of a 16 amino acid motif in the third exon of the dopamine D4 receptor gene (DRD4) and the personality trait of novelty seeking has been reported.

MAOA drug cocaine 23755928 A MAOA gene*cocaine severity interaction on impulsivity and neuropsychological measures of orbitofrontal dysfunction: preliminary results. MAOA drug cocaine 23755928 Based on previous evidence of a MAOA gene*cocaine use interaction on orbitofrontal cortex volume attrition, we tested whether the MAOA low activity variant and cocaine use severity are interactively associated with impulsivity and behavioral indices of orbitofrontal dysfunction: emotion recognition and decision making. MAOA drug cocaine 23755928 72 cocaine dependent individuals and 52 non drug using controls (including healthy individuals and problem gamblers) were genotyped for the MAOA gene and tested using the UPPS P Impulsive Behavior Scale, the Iowa Gambling Task and the Ekman's Facial Emotions Recognition Test. MAOA drug cocaine 23755928 To test the main hypothesis, we conducted hierarchical multiple regression analyses including three sets of predictors: (1) age, (2) MAOA genotype and severity of cocaine use, and (3) the interaction between MAOA genotype and severity of cocaine use. MAOA drug cocaine 23755928 We computed the statistical significance of the prediction change yielded by each consecutive set, with 'a priori' interest in the MAOA*cocaine severity interaction. MAOA drug cocaine 23755928 We found significant effects of the MAOA gene*cocaine use severity interaction on the emotion recognition scores and the UPPS P's dimensions of Positive Urgency and Sensation Seeking: Low activity carriers with higher cocaine exposure had poorer emotion recognition and higher Positive Urgency and Sensation Seeking.

MAOA drug alcohol 19120058 Effects of MAOA genotype, alcohol consumption, and aging on violent behavior. MAOA drug alcohol 19120058 However, how MAOA LPR modulates the effects of other factors such as alcohol consumption related to antisocial behavior is not completely understood. MAOA drug alcohol 19120058 This study examines the conjunct effect of MAOA LPR, alcohol consumption, and aging on the risk for violent behavior. MAOA drug alcohol 19120058 The risk for committing new acts of violence increased by 2.3% for each kilogram of increase in yearly mean alcohol consumption (p = 0.004) and decreased by 7.3% for every year among offenders carrying the high activity MAOA genotype. MAOA drug alcohol 19120058 In contrast, alcohol consumption and aging failed to affect violent behavior in the low activity MAOA genotyped offenders. MAOA drug alcohol 19120058 Finnish high activity MAOA genotyped risk alcoholics exhibiting antisocial behavior, high alcohol consumption, and abnormal alcohol related impulsive and uncontrolled violence might represent an etiologically distinct alcohol dependence subtype.

MAOA drug psychedelics 19076925 Considering that hyperthermia has been shown to contribute to the neurotoxic effects of MDMA, another objective of the present study was to evaluate the body temperature changes mediated by MDMA with a MAO A selective inhibition by clorgyline. MAOA drug psychedelics 19076925 The obtained results demonstrated that the administration of a neurotoxic binge dose of MDMA to an adolescent rat model previously treated with the specific MAO A inhibitor, clorgyline, resulted in synergistic effects on serotonin (5 HT) mediated behaviour and body temperature, provoking high mortality. MAOA addiction intoxication 19076925 The obtained results demonstrated that the administration of a neurotoxic binge dose of MDMA to an adolescent rat model previously treated with the specific MAO A inhibitor, clorgyline, resulted in synergistic effects on serotonin (5 HT) mediated behaviour and body temperature, provoking high mortality. MAOA drug psychedelics 19076925 Inhibition of MAO A by clorgyline administration had no protective effect on MDMA induced alterations on brain mitochondria (increased lipid peroxidation, protein carbonylation and decrease in the expression of the respiratory chain subunits NDII and COXI), although it aggravated MDMA induced decrease in the expression of COXI. MAOA drug psychedelics 19076925 These results reinforce the notion that the concomitant use of MAO A inhibitors and MDMA is counter indicated because of the resulting severe synergic toxicity.

MAOA drug nicotine 17912044 This study examined the effects of three MAOIs (phenelzine, clorgyline and pargyline) with varying selectivity for MAOA and MAOB in the nicotine drug discrimination procedure in rats. MAOA drug nicotine 17912044 Although the selective MAOA inhibitor clorgyline (3 56 mg/kg) and the selective MAOB inhibitor pargyline (3 56 mg/kg) did not elicit any nicotine appropriate responding, partial substitution was obtained with the nonselective MAO inhibitor phenelzine (1 17 mg/kg). MAOA drug nicotine 17912044 These findings indicate that concomitant inhibition of MAOA and MAOB can enhance the discriminative stimulus effect of nicotine in rats.

MAOA addiction dependence 17476365 Monoamine oxidase A polymorphisms might modify the association between the dopamine D2 receptor gene and alcohol dependence. MAOA drug alcohol 17476365 Therefore, the present study investigates whether the association between the dopamine D2 receptor (DRD2) gene and alcoholism is affected by different polymorphisms of the MAO type A (MAOA) gene. MAOA drug alcohol 17347351 For example, it has been shown that childhood maltreatment interacts with a monoamine oxidase A (MAOA) gene variant to predict antisocial behavior that is often associated with alcoholism, and an interaction between early life stress and a serotonin transporter promoter variant predicts alcohol abuse in nonhuman primates and depression in humans.

MAOA addiction reward 17229101 Monoamine oxidase A rather than monoamine oxidase B inhibition increases nicotine reinforcement in rats. MAOA drug nicotine 17229101 It has been shown that tobacco smoke contains monoamine oxidase (MAO) A and B inhibitors and decreases MAO A and MAO B activity in smokers. MAOA drug nicotine 17229101 Here, we investigated the effects of clorgyline hydrochloride (irreversible MAO A inhibitor; 2 mg/kg/day), selegiline (irreversible MAO B inhibitor; 4 mg/kg) and the beta carboline norharmane hydrochloride (reversible MAO B inhibitor; 5 mg/kg/day) treatments on nicotine self administration (30 microg/kg/infusion, free base) in rats. MAOA drug nicotine 17229101 Taken together, these results indicate that MAO A inhibition interacts with nicotine to enhance its rewarding effects in rats and suggest that other compounds present in tobacco, such as beta carboline, may also play an important role in sustaining smoking behavior in humans.

MAOA drug alcohol 12824808 Neither antisocial personality disorder nor antisocial alcoholism is associated with the MAO A gene in Han Chinese males. MAOA drug alcohol 12824808 Recent studies on the genetics of alcoholism have suggested an association between antisocial alcoholism and the MAO A gene. MAOA drug alcohol 12824808 Consequently, the finding of an association between the MAO A gene and alcoholism or antisocial personality disorder seems tenuous. MAOA drug alcohol 12824808 Therefore, association studies of alcoholism or antisocial personality disorder in Chinese may be more reliable if pure antisocial alcoholics, pure antisocial personality disorders, and normal controls as MAO A gene are examined. MAOA drug alcohol 12824808 In this study, the associations among antisocial alcoholism, antisocial personality disorder, and the uVNTR and EcoRV polymorphisms of the MAO A gene, both individually and as a haplotype, were investigated among male adults recruited from jails in Taipei.

MAOA drug amphetamine 8473997 l Deprenyl produced clear generalization to the d amphetamine stimulus only at very high doses of 17.0 to 30.0 mg/kg, doses about 10 fold higher than those that have a selective action on MAO B vs. MAO A and which start to have marked rate decreasing actions on food reinforced responding. MAOA addiction intoxication 24925295 It is found that in rats predisposed to catalepsy the threshold of audiogenic seizures is elevated; the activity of tryptophan hydroxylase in striatum is higher in rats predisposed to catalepsy genetically and due to a chronic methylphenidate intoxication as compared to control animals; noradrenaline content and noradrenaline/dopamine ratio is lower in the diencephalon of rats predisposed to catalepsy than in controls; cataleptic rats have a higher content of homovanillic acid in N.accumbens , and a higher frequency of inversion of hemispheric asymmetry as estimated by levels of dopamine and dioxyphenylacetic acid in N.accumbens and caudate nucleus, than normal rats; MAO B/MAO A ratio is higher in the brain stem of cataleptic than normal rats.

MAOA drug benzodiazepine 6121956 Biochemical studies have revealed beta carbolines' several actions, including inhibition of MAO A, competitive inhibition of 5 HT uptake, general inhibition of Na+ dependent transports, binding to benzodiazepine and opiate receptors and probable action on dopamine receptors, which may all participate to a variable degree in the actions of different beta carbolines.

SLC1A2 drug cocaine 28919080 However, the mechanism(s) by which cocaine downregulates GLT 1 protein remains unknown. SLC1A2 drug cocaine 28919080 We used qRT PCR to examine gene expression of GLT 1 splice isoforms (GLT 1A, GLT 1B) in the NAc, prelimbic cortex (PL) and basolateral amygdala (BLA) of rats, following two widely used models of cocaine self administration: short access (ShA) self administration, and the long access (LgA) self administration/incubation model. SLC1A2 drug cocaine 28919080 While downregulation of GLT 1 protein is observed following ShA cocaine self administration and extinction, this model did not lead to a change in GLT 1A or GLT 1B gene expression in any brain region examined.

SLC1A2 drug alcohol 28687200 Furthermore, a history of alcohol consumption did not alter xCT and GLT 1 expression relative to alcohol naïve controls. SLC1A2 drug alcohol 28687200 These results indicate that while Cef reduces alcohol consumption in outbred rats, its ability to do so is not associated with an increase in GLT 1 expression.

SLC1A2 drug cocaine 28495973 In the absence of cocaine or ceftriaxone treatment, xCT knockdown in the NAc increased the expression of both GluA1 and GluA2 without affecting GLT 1 expression while GLT 1 knockdown had no effect. SLC1A2 drug cocaine 28495973 While upregulation of both xCT and GLT 1 are essential to the ability of ceftriaxone to attenuate cue induced reinstatement of cocaine seeking, each protein uniquely affects the expression of other glutamate receptor and transporter proteins.

SLC1A2 drug opioid 27461080 By expression of a dominant negative TNF peptide via lentiviral vector injection in rat PAG to sequester soluble TNF (solTNF), we demonstrate that solTNF mediates morphine tolerance induced by TLR4 signaling, stimulates neuroinflammation (increased IL 1β and TLR4 mRNA), and disrupts glutamate reuptake (decreased GLT 1 and GLAST mRNA). SLC1A2 drug alcohol 27207718 The increase in basal glutamate was not associated with changes in the surface expression of GLT 1, however, a decrease in slope of the no net flux dialysis function was observed following ethanol consumption, indicating a potential decrease in glutamate reuptake.

GRIN2B addiction relapse 31706797 After a molecular analysis of ketamine modulation of GluN2B, GluA1 and mGluR5 receptors levels in nucleus accumbens, hippocampus and amygdala, two behavioural models were used to investigate ketamine effects: i) context induced renewal of sucrose seeking, and ii) sucrose memory reconsolidation. GRIN2B drug psychedelics 31706797 At the molecular level, ketamine i) decreased GluN2B, GluA1 and mGluR5 receptors in hippocampus, ii) decreased GluA1 and mGluR5 but increased GluN2B in nucleus accumbens and iii) increased GluN2B and mGluR5 in amygdala. GRIN2B drug alcohol 31636539 In adult mice, chronic ethanol induces long term changes in GluN2B containing NMDA receptors (NMDARs) of the BNST. GRIN2B drug psychedelics 31541650 In this study, we examined the possible effects of ketamine on calcium/calmodulin dependent protein kinase II α (CaMKIIα) and N methyl d aspartate receptor (NMDAR) subunit NR2B in a mouse model of remifentanil induced postoperative hyperalgesia (RIPH) in the primary somatosensory cerebral cortex (SI) region. GRIN2B drug cocaine 31361029 Administration of the GluN2A and GluN2B NMDA receptor antagonists, NVP AAM077 and ifenprodil, respectively, immediately following recall abrogated an established cocaine place preference, while preventing the activation of GSK3β in the amygdala, nucleus accumbens, and hippocampus during cocaine memory reactivation. GRIN2B drug opioid 31220544 Furthermore, spinal inhibition of SGK1 suppressed morphine induced phosphorylation of nuclear factor kappa B (NF κB) p65 and upregulation of NMDAR NR1 and NR2B expression in the spinal dorsal horn. GRIN2B drug opioid 31220544 In addition, morphine induced upregulation of NR2B, but not NR1, was significantly abolished by intrathecal pretreatment with PDTC, a specific NF κB activation inhibitor. GRIN2B drug opioid 31220544 Finally, spinal delivery of SGK1 small interfering RNA exhibited similar inhibitory effects on morphine induced tolerance, phosphorylation of NF κB p65, as well as upregulation of NR1 and NR2B expression. GRIN2B addiction aversion 31087376 In our experiments, adolescent and adult Sprague Dawley rats were tested for CTA following challenge with one of the following pharmacological agents: glutamatergic AMPA1 receptor antagonist NBQX, glutamatergic N methyl d aspartate NR2B receptor antagonist ifenprodil, and extrasynaptic GABAA receptor agonist THIP to determine whether these induced age specific aversive sensitivities like those seen with EtOH. GRIN2B addiction aversion 31087376 Thus, only antagonism of NR2B receptors in male rats mimicked age specific sensitivities to the aversive effects of EtOH. GRIN2B addiction intoxication 31056842 Memory and plasticity impairment after binge drinking in adolescent rat hippocampus: GluN2A/GluN2B NMDA receptor subunits imbalance through HDAC2. GRIN2B addiction intoxication 31056842 Previously, we reported that two binge like exposures to EtOH (3 g/kg, ip, 9 h apart) in adolescent rats abolished long term synaptic depression (LTD) in hippocampus slices, induced learning deficits, and increased N methyl d aspartate (NMDA) receptor signaling through its GluN2B subunit after 48 hours. GRIN2B addiction intoxication 31056842 In conclusion, the memory impairing effects of two binge like EtOH exposure involve NMDA receptor dependent LTD deficits due to a GluN2A/GluN2B imbalance resulting from changes in GluN2B expression induced by HDAC2.

GRIN2B addiction withdrawal 30733663 We then analyzed the expression levels of presynaptic (vGlut1, vGlut2, CB1 receptor, synaptophysin) and postsynaptic (PSD95, GluN1, GluN2A, GluN2B, GluA1, GluA2, mGluR1 and mGluR5) proteins after 7 days EtOH incubation or after EtOH withdrawal. GRIN2B drug amphetamine 30693312 We propose that METH SA selectively upregulates GluN2B lacking NMDA receptors (NMDAR) in the PFC of female rats. GRIN2B drug alcohol 30536923 We show that systemic administration of AZD0530 prevents alcohol induced Fyn activation and GluN2B phosphorylation in the DMS of mice. GRIN2B drug cocaine 30315226 Finally, loss of GluD1 increased the GluN2B subunit contribution to NMDA receptor currents in MSNs and a partial agonist of GluN2B containing NMDA receptors normalized the higher active cofilin and cocaine preference in GluD1 KO mice. GRIN2B drug opioid 30240785 The expressions of Trx 1, N methyl d aspartate receptor 2B subunit (NR2B), phosphorylated Ca2+/calmodulin dependent protein kinase II (p CaMKII), phosphorylated extracellular signaling regulated kinases (p ERK), and phosphorylated cAMP response element binding protein (p CREB) were induced in nucleus accumbens (NAc) and hippocampus by morphine or GGA, whereas these proteins were not changed by morphine in GGA treated mice.

GRIN2B addiction reward 29982266 Genetic loss of GluN2B in D1 expressing cell types enhances long term cocaine reward and potentiation of thalamo accumbens synapses. GRIN2B drug cocaine 29982266 Transient upregulation of GluN2B containing NMDA receptors (R) in the nucleus accumbens (NAc) is proposed as an intermediate to long term AMPAR plasticity associated with persistent cocaine related behaviors. GRIN2B drug cocaine 29982266 However, cell type and input specific contributions of GluN2B underlying lasting actions of cocaine remain to be elucidated. GRIN2B drug cocaine 29982266 We utilized GluN2B cell type specific knockouts and optogenetics to deconstruct the role of GluN2B in cocaine induced NAc synaptic and behavioral plasticity. GRIN2B addiction reward 29982266 While reward learning was unaffected, loss of GluN2B in D1 dopamine receptor expressing cells (D1) led to prolonged retention of reward memory. GRIN2B drug cocaine 29982266 In D1 GluN2B / mice, the potentiation of mThal D1(+) NAc AMPAR function persisted following withdrawal, corresponding with continued expression of cocaine reward behavior. GRIN2B addiction reward 29982266 In D1 GluN2B / mice, the potentiation of mThal D1(+) NAc AMPAR function persisted following withdrawal, corresponding with continued expression of cocaine reward behavior. GRIN2B addiction withdrawal 29982266 In D1 GluN2B / mice, the potentiation of mThal D1(+) NAc AMPAR function persisted following withdrawal, corresponding with continued expression of cocaine reward behavior. GRIN2B addiction reward 29982266 These data suggest NAc GluN2B containing NMDARs serve a feedback role and may weaken reward related memories. GRIN2B drug amphetamine 29981334 We also examined the expression of N methyl D asparate (NMDA) receptor 2B subunit (GluN2b), the levels of phosphorylated extracellular signal regulated kinase (p ERK) and phosphorylated cAMP response element binding protein (p CREB) in the NAc by western blot analysis, and found that the GluN2b expression, p ERK and p CREB levels were increased in the NAc in response to low dose METH in AAV shRNA mTrx 1 mice, but were not changed in control and AAV vehicle mice. GRIN2B drug amphetamine 29981334 These data indicate that the increased GluN2b expression, and p ERK and p CREB levels in the NAc of AAV shRNA mTrx 1 mice may be responsible for the METH primed reinstatement. GRIN2B addiction relapse 29981334 These data indicate that the increased GluN2b expression, and p ERK and p CREB levels in the NAc of AAV shRNA mTrx 1 mice may be responsible for the METH primed reinstatement. GRIN2B addiction addiction 29766293 Data obtained using Western blotting technique showed a significant increase in the level of GluN1 and GluN2B, but not in GluN2A subunits in all the three regions (mPFC, lPFC, and OFC) of men whom suffered from addiction as compared to the appropriate controls. GRIN2B addiction addiction 29766293 These findings showed a novel role for GluN1, GluN2B subunits, rather than the GluN2A subunit of NMDARs, in the pathophysiology of addiction and suggested their role in the drug induced plasticity of NMDARs. GRIN2B drug alcohol 29704590 Protective influences of N acetylcysteine against alcohol abstinence induced depression by regulating biochemical and GRIN2A, GRIN2B gene expression of NMDA receptor signaling pathway in rats.

GRIN2B drug cocaine 29380665 To evaluate the role of glutamate on BDNF independent changes, we investigated the expression of the transporter GLT 1 and the activation of the NMDA receptor subunit GluN2B, which were both increased in the PL cortex while reduced in the IL cortex.Conclusions: Our results show that adolescent cocaine exposure modulates BDNF system early after treatment in the mesocorticolimbic pathway, identifying a complex but specific set of changes that could provide clues for treatment. GRIN2B addiction reward 29305627 Antagonism at the NR2B subunit of NMDA receptors induces increased connectivity of the prefrontal and subcortical regions regulating reward behavior. GRIN2B drug psychedelics 29305627 Evidence indicates that ketamine's rapid antidepressant efficacy likely results from its antagonism of NR2B subunit containing NMDA receptors (NMDAR). GRIN2B drug psychedelics 29305627 Since ketamine equally blocks NR2A and NR2B containing NMDAR, and has affinity to other receptors, NR2B selective drugs might have improved therapeutic efficiency and side effect profile. GRIN2B drug psychedelics 29305627 We aimed to compare the effects of (S) ketamine and two different types of NR2B selective antagonists on functional brain networks in rats, in order to find common circuits, where their effects intersect, and that might explain their antidepressant action. GRIN2B drug psychedelics 29305627 The effects common to ketamine and NR2B selective compounds were localized to the same brain regions as those reported in depression, but in the opposite direction. GRIN2B addiction reward 29305627 The upregulation of the reward circuitry might partially underlie the antidepressant and anti anhedonic effects of the antagonists and could potentially serve as a translational imaging phenotype for testing putative antidepressants, especially those targeting the NR2B receptor subtype. GRIN2B drug cocaine 29196318 Despite blocking tissue GluA1 increases in cocaine self administering animals, the HSV dnGluN1 treatment resulted in increased membrane levels of GluA1 and GluN2B, along with markedly higher locomotor responses to intra VTA infusions of AMPA, suggesting a paradoxical increase in VTA AMPA receptor responsiveness. GRIN2B addiction withdrawal 29139560 This increase persisted during EtOH withdrawal, along with an increase in NR2B Y1472 phosphorylation, mature brain derived neurotrophic factor, and phosphorylated TrkB. GRIN2B drug opioid 29116553 Evidence suggests that the dopamine receptor rate limiting enzyme, tyrosine hydroxylase (TH), and the glutamate receptor, N methyl D aspartate receptor 2B (NR2B), contribute to morphine dependence.

GRIN2B drug alcohol 29030082 We additionally examined the effects of ADX 47273 on the expression of the NMDA receptors subunit, GluN2B, in the hippocampus and prefrontal cortex, on the 13th day of ethanol withdrawal. GRIN2B addiction withdrawal 29030082 We additionally examined the effects of ADX 47273 on the expression of the NMDA receptors subunit, GluN2B, in the hippocampus and prefrontal cortex, on the 13th day of ethanol withdrawal. GRIN2B drug alcohol 29030082 The 13th day of ethanol abstinence decreased the expression of the GluN2B subunit in the selected brain regions, but ADX 47273 administration increased it. GRIN2B drug cocaine 28973019 Cocaine self administration increased the A/N ratio and GluN2B NMDARs in WT MSNs and, although the A/N ratio also increased in KO MSNs, this was accompanied by fewer GluN2B NMDARs and an appearance of calcium permeable AMPARs. GRIN2B addiction reward 28973019 Finally, to examine the consequences of reduced basal GluN2B NMDARs in reward processing seen in KO mice, we chronically infused ifenprodil, a GluN2B antagonist, into the NAc shell of WT mice. GRIN2B drug psychedelics 28948570 Since GluN2B, via inhibition of ERK, regulates the membrane expression of GluA1, we measured ERK2 phosphorylation in the crude synaptosomal fraction of these brain regions, which was significantly reduced suggesting that ketamine induced phosphorylation of αCaMKII promotes GluN2B (S1303) phosphorylation that, in turn, inhibits ERK 2 signaling, an effect that results in reduced membrane expression and phosphorylation of GluA1. GRIN2B drug psychedelics 28948570 Taken together, our findings point to αCaMKII autophosphorylation as a critical signature of ketamine self administration providing an intracellular mechanism to explain the different effects caused by αCaMKII autophosphorylation on the post synaptic GluN2B and GluA1 mediated functions.

GRIN2B drug benzodiazepine 21277878 Importantly, the reduced inhibition also operated to enhance NMDARs functions after peripheral inflammation, because spinal injection of diazepam to rescue the inhibition in inflamed mice greatly depressed PKA phosphorylation of NR1 S897, reduced the synaptic concentration of NR1/NR2B and meanwhile, alleviated the inflammatory pain. GRIN2B drug cocaine 21232547 Furthermore, because cocaine generated silent synapses are enriched in NMDARs containing the NR2B subunit, the enhanced NR2B signaling may set up a selective recruitment of certain types of AMPARs.

GRIN2B drug cocaine 21055728 We also demonstrate that the D1R/Src family kinases/NR2B pathway is responsible for ERK activation by cocaine in vivo. GRIN2B drug cocaine 21055728 Our results show that potentiation of NR2B containing NMDAR by D1R is necessary and sufficient to trigger cocaine induced ERK activation. GRIN2B drug alcohol 20947635 These observations demonstrate that 1) accumbal synaptic depression is mediated by NR2B receptors, 2) accumbal synaptic depression is highly sensitive to both acute and chronic ethanol exposure, and 3) alterations in this synaptic process may constitute a neural adaptation that contributes to the induction and/or expression of ethanol dependence.

GRIN2B drug opioid 20869946 It is concluded that morphine does not affect the neurosteroid modulatory effect on ifenprodil binding in the rat hippocampus or hypothalamus but does significantly affect both the expression of the NR2B subunit and the 3α5βS modulatory effect on ifenprodil binding in the frontal cortex. GRIN2B drug opioid 20869946 It is suggested that the observed effect of long term morphine on the properties of NR2B in the frontal cortex may be associated with the mechanism underlying the development of opiate dependence.

GRIN2B drug benzodiazepine 20853509 Therefore, in this study ultrastructural evidence for possible reductions in NMDAR GluN1, GluN2A, and GluN2B subunits was sought at CA1 stratum radiatum synapses in proximal dendrites using postembedding immunogold labeling of tissues from rats withdrawn for 2 days from 1 week daily oral administration of the benzodiazepine, flurazepam (FZP). GRIN2B addiction withdrawal 20853509 Similar decreases were observed for GluN2B subunits; however, the relative lateral distribution of GluN2B immunolabeling within the postsynaptic density did not change after BZ withdrawal. GRIN2B addiction withdrawal 20853509 The data therefore provide direct evidence for reduced synaptic GluN1/GluN2B receptors and preservation of GluN1/GluN2A receptors in the CA1 stratum radiatum region during BZ withdrawal. GRIN2B drug alcohol 20831600 This resistance occurred without an increase in the NMDAR subunit expression but was associated with decreases in the levels of phospho Y 1472 NR2B, increases in the levels of STEP33, increases in phospho p38 mitogen activated protein kinase (pp38 MAPK), and acquisition of tolerance to the sedative effects of ethanol.

GRIN2B drug amphetamine 20649838 In this line, repeated amphetamine injections led to a twofold increase in the amount of the NMDA receptor subunit NR2B in Go2α / mice resulting in an enhanced inhibition of the indirect DA pathway. GRIN2B drug alcohol 20603193 After 2 weeks of ethanol vapor exposure N methyl d aspartate receptor NR1 subunit (NR1), N methyl d aspartate receptor NR2A subunit (NR2A), and N methyl d aspartate receptor NR2B subunit (NR2B) subunit expression was found to be increased in hippocampus of the adults. GRIN2B drug alcohol 20603193 In contrast, 2 weeks of ethanol exposure resulted in no significant changes in NR1 and NR2B subunits and a reduction NR2A subunit expression in hippocampus in adolescents. GRIN2B drug alcohol 20603193 In frontal cortex, 2 weeks of chronic ethanol exposure produced decreases in NR1 subunit expression in both adults and adolescents but also produced decreases in NR2A and NR2B subunit expression in adults that returned or exceeded control levels by 2 weeks following withdrawal from ethanol vapor. GRIN2B addiction withdrawal 20603193 In frontal cortex, 2 weeks of chronic ethanol exposure produced decreases in NR1 subunit expression in both adults and adolescents but also produced decreases in NR2A and NR2B subunit expression in adults that returned or exceeded control levels by 2 weeks following withdrawal from ethanol vapor. GRIN2B drug opioid 20519536 Morphine exposure and withdrawal increase phosphorylation of NR1 and NR2B receptors, ERK1/2, calmodulin dependent kinase II, and cAMP response element binding proteins; and such phosphorylation is suppressed by either spinal inhibition or targeted mutation of MMP 9. GRIN2B addiction withdrawal 20519536 Morphine exposure and withdrawal increase phosphorylation of NR1 and NR2B receptors, ERK1/2, calmodulin dependent kinase II, and cAMP response element binding proteins; and such phosphorylation is suppressed by either spinal inhibition or targeted mutation of MMP 9. GRIN2B drug opioid 20519536 Further, spinal administration of exogenous MMP 9 induces morphine withdrawal like behavioral signs and mechanical allodynia, activates NR1 and NR2 receptors, and downregulates integrin beta1, while a function neutralizing antibody against integrin beta1 suppresses MMP 9 induced phosphorylation of NR1 and NR2B. GRIN2B addiction withdrawal 20519536 Further, spinal administration of exogenous MMP 9 induces morphine withdrawal like behavioral signs and mechanical allodynia, activates NR1 and NR2 receptors, and downregulates integrin beta1, while a function neutralizing antibody against integrin beta1 suppresses MMP 9 induced phosphorylation of NR1 and NR2B. GRIN2B drug opioid 20519536 Thus, we hypothesize that spinal MMP 9 may contribute to the development of morphine dependence primarily through neuronal activation and interaction with NR1 and NR2B receptors via integrin beta1 and NO pathways.

GRIN2B addiction reward 20422365 Amphetamine CPP rats showed a significantly increased NR2B mRNA and protein expression in medial prefrontal cortex and hippocampal CA1 areas as compared to the control group. GRIN2B drug amphetamine 20422365 Rhynchophylline reversed NR2B mRNA and protein levels induced by amphetamine but rhynchophylline by itself had no effect on NR2B expression in control rats. GRIN2B drug amphetamine 20422365 These results indicate that rhynchophylline inhibits the expression of amphetamine induced rewarding effect, and this action might be related to down regulation of NR2B expression in medial prefrontal cortex and hippocampal CA1 area. GRIN2B drug alcohol 20098704 We recently reported that NMDA receptor 2B (NR2B) gene expression was persistently up regulated following chronic intermittent ethanol (CIE) treatment. GRIN2B addiction withdrawal 20098704 Analysis of individual CpG methylation sites within the NR2B 5'regulatory area revealed three regions with clusters of site specific CpG demethylation following CIE treatment and withdrawal. GRIN2B drug alcohol 20098704 These results suggest an important role of DNA demethylation in mediating CIE induced NR2B gene up regulation, thus implicating a novel molecular site of alcohol action. GRIN2B drug alcohol 20008487 After chronic ethanol exposure, there was a significant increase in the clustering of NR1 and NR2B subunits and their colocalization with the synaptic proteins synaptophysin and postsynaptic density protein 95, respectively.

GRIN2B drug cocaine 19607791 Furthermore, this cocaine induced generation of silent synapses is mediated by membrane insertions of new, NR2B containing N methyl D aspartic acid receptors (NMDARs). GRIN2B drug cocaine 19524640 We found that inhibition of NR2A containing NMDARs by NVP AAM077, or NR2B containing receptors by ifenprodil, blocked cocaine induced increase in the AMPAR/NMDAR currents ratio, a measure of long term potentiation (LTP) in vivo, in VTA neurons 24h following a single cocaine injection. GRIN2B drug cocaine 19474322 Here, we show that repeated noncontingent cocaine injections increased NAc NMDAR subunits, NR1, NR2A, and NR2B 21 d, but not 1 d, after withdrawal from cocaine.

GRIN2B drug psychedelics 19421743 Three distinct patterns of antagonist effect were evident from the VI assays used: a uniform decrease in responding produced by (S) (+) ketamine, memantine and NVP AAM077, a uniform increase in responding caused by the NR2B subunit preferring antagonists Ro 25 6981 and CP 101 606, and variable bidirectional effects of PCP, SDZ 220,581 and MK 801.

GRIN2B addiction withdrawal 19350219 NMDA receptors and especially the NR2B receptor subtype play a crucial role during chronic ethanol consumption and alcohol withdrawal. GRIN2B drug alcohol 19350219 Therefore, the NR2B receptor subtype expression in peripheral blood cells of 32 male patients suffering from alcohol dependency were assessed through quantitative RT PCR and to explore regulating epigenetic mechanisms, a methylation analysis was conducted using bisulfite sequencing of a fragment of the NR2B promoter region. GRIN2B addiction withdrawal 19350219 The expression of the NR2B receptor increased significantly during the first 24 h of withdrawal treatment (day 1; t = 4.1, P = 0.001), and also on and day 3 (t = 2.4; P = 0.029). GRIN2B drug alcohol 19350219 The severity of alcohol drinking pattern, measured by lifetime drinking and daily ethanol intake, was negatively correlated with the methylation of a defined cluster of five CPG sites within the NR2B promoter (lifetime drinking: Spearman's rho = 0.55; P = 0.013; daily ethanol intake: rho = 0.46; P = 0.043). GRIN2B drug amphetamine 19349975 We examined the turnover and trafficking of NMDA receptors and found that chronic exposure to the psychostimulant amphetamine (AMPH) induced selective downregulation of NMDA receptor NR2B subunits in the confined surface membrane pool of rat striatal neurons at synaptic sites. GRIN2B drug amphetamine 19349975 Behaviorally, genetic disruption of NR2B induced and restoration of NR2B loss prevented behavioral sensitization to AMPH. GRIN2B addiction sensitization 19349975 Behaviorally, genetic disruption of NR2B induced and restoration of NR2B loss prevented behavioral sensitization to AMPH.

GRIN2B drug alcohol 19077056 Repeated ethanol administration also down regulates the expression of DRD2 and NMDAR2B phosphorylation in prefrontal cortex of adolescent animals, but not of adult rats. GRIN2B drug cocaine 19046409 Here we show that application of cocaine both in slices and in vivo induced an increase in tyrosine phosphorylation of the NR2A, but not the NR2B subunit of the NMDAR in juvenile rats. GRIN2B drug cocaine 19046409 Cocaine induced an increase in the activity of both Fyn and Src kinases, and the Src protein tyrosine kinase (Src PTKs) inhibitor, 4 amino 5 (4 chlorophenyl) 7 (t butyl)pyrazolo[3,4 d]pyrimidine (PP2), abolished both cocaine induced increase in tyrosine phosphorylation of the NR2A subunit and the increase in the expression of NR1, NR2A, and NR2B in the VTA.

GRIN2B drug opioid 18851757 These findings indicate that impaired NMDAR dependent neuronal plasticity following repeated morphine injection in PSD 93 knockout mice is attributed to PSD 93 deletion induced alterations of synaptic NR2A and NR2B expression in dorsal horn and forebrain cortex neurons. GRIN2B drug alcohol 18849153 Fyn tyrosine kinase is a member of the Scr family that phosphorylates the NR2A and NR2B subunits of the NMDA receptors reducing the inhibitory effects of ethanol and therefore may regulate the individual sensitivity to ethanol. GRIN2B drug opioid 18803856 Cingulate NMDA NR2B receptors contribute to morphine induced analgesic tolerance. GRIN2B drug opioid 18803856 In this study, Ro 256981, an antagonist of the NMDA receptor subunit NR2B, was used to reduce the expression of analgesic tolerance to morphine. GRIN2B drug opioid 18803856 Since NMDA NR2B receptors in the anterior cingulate cortex (ACC) play roles in the establishment of LTP and fear memory, we explored their role in changes that occur in this region after chronic morphine. GRIN2B drug opioid 18803856 Both systemic and intra ACC inhibition of NR2B in morphine tolerant animals inhibited the expression of analgesic tolerance. GRIN2B drug opioid 18803856 This study suggests that selective inhibition of NMDA NR2B receptors may prove useful in combating the development of analgesic tolerance to morphine and proposes a novel role for the ACC in opioid tolerance and morphine induced changes in synaptic plasticity.

GRIN2B drug psychedelics 18419818 The aim of the present study was to investigate the effect of repeated intermittent MDMA administration upon gene transcript expression of the glutamate transporters (EAAT1, EAAT2 1, EAAT2 2), the glutamate receptor subunits of AMPA (GluR1, GluR2, GluR3), the glutamate receptor subunits of NMDA (NR1, NR2A and NR2B), as well as metabotropic glutamate receptors (mGluR1, mGluR2, mGluR3, mGluR5) in six different brain regions. GRIN2B drug alcohol 18369402 Especially, the expression of the NR2B and certain splice variant forms of the NR1 subunits were increased in primary neuronal cultures treated intermittently with ethanol. GRIN2B drug alcohol 18369402 In accordance with these changes, the inhibitory potential of NR2B subunit selective NMDAR antagonists is also increased, demonstrating excellent potency against alcohol withdrawal induced in vitro cytotoxicity.

GRIN2B drug alcohol 18369402 Although in vivo data are few with these compounds, according to the effectiveness of the classic NMDAR antagonists in attenuation, not only the physical symptoms, but also some affective and motivational components of alcohol withdrawal, novel NR2B subunit selective NMDAR antagonists may offer a preferable alternative in the pharmacotherapy of alcohol dependence.

GRIN2B drug alcohol 18358639 The relative mRNA expression of exon 5 inclusion/exclusion variants of the NR1 subunit, and the relative expression of NR2A, NR2B and NR2C subunits was examined in rats subjected to long term free choice, alcohol self administration with repeated alcohol deprivation phases. GRIN2B drug alcohol 17982573 These observations led us to propose a molecular model for ethanol induced plasticity at excitatory synapses in which increases in NR2B containing NMDA receptors and PSD 95 at the PSD provide an expanded scaffolding platform for the recruitment and activation of signaling molecules that regulate spine actin dynamics, protein translation, and synaptic plasticity. GRIN2B drug cocaine 17950706 In both species, withdrawal from repeated cocaine administration down regulated Homer1b/c and Homer2a/b within the shell, but not the core, of the nucleus accumbens (NAC), and the reduced Homer levels were accompanied by decreases in mGluR1a, NR2a and NR2b. GRIN2B addiction withdrawal 17950706 In both species, withdrawal from repeated cocaine administration down regulated Homer1b/c and Homer2a/b within the shell, but not the core, of the nucleus accumbens (NAC), and the reduced Homer levels were accompanied by decreases in mGluR1a, NR2a and NR2b. GRIN2B drug cocaine 17950706 In the PFC, repeated cocaine up regulated Homer2a/b, mGluR1 and NR2b expression, without affecting Homer1b/c levels. GRIN2B drug amphetamine 17651730 Western blot analysis of the caudate after methamphetamine revealed little change in Alpha Amino 3 Hydroxy 5 Methyl 4 Isoxazole Propionic Acid (AMPA) GluR1 or N Methyl d Aspartate (NMDA) NR2B subunits, or their phosphorylation state. GRIN2B drug amphetamine 17651730 Methamphetamine also increased levels of PFC NR2B subunit, but these increases were not attenuated by deprenyl. GRIN2B drug alcohol 17625498 Alcohol inhibits NR2B containing NMDA receptors in the ventral bed nucleus of the stria terminalis. GRIN2B drug alcohol 17625498 While genetic removal of NR2A did not alter the magnitude of ethanol inhibition, pharmacological blockade of NR2B rendered synaptically activated NMDARs insensitive to ethanol inhibition. GRIN2B drug opioid 17447466 Role of tyrosine kinase dependent phosphorylation of NR2B subunit containing NMDA receptor in morphine reward. GRIN2B addiction reward 17447466 Role of tyrosine kinase dependent phosphorylation of NR2B subunit containing NMDA receptor in morphine reward. GRIN2B drug opioid 17447466 We previously demonstrated that the morphine induced rewarding effect was dramatically suppressed by cotreatment with an NR2B subunit containing N methyl D aspartate (NMDA) receptor antagonist ifenprodil. GRIN2B drug opioid 17447466 Therefore we propose here that the NR2B subunit containing NMDA receptor may be involved in the rewarding effect of morphine.

GRIN2B drug cocaine 17393777 The results suggest that NR2B containing NMDA receptor mediated mechanisms modulate the discriminative stimulus effects of cocaine in rhesus monkeys. GRIN2B drug alcohol 17392475 Ethanol induces long term facilitation of NR2B NMDA receptor activity in the dorsal striatum: implications for alcohol drinking behavior. GRIN2B drug alcohol 17392475 We found that, in the dorsal striatum, alcohol (ethanol) exposure produced an increase in the phosphorylation of the NR2B subunit of the NMDAR, and a corresponding increase in the activity of Fyn kinase, which phosphorylates NR2B. GRIN2B drug alcohol 17392475 We further observed an ethanol mediated long term facilitation (LTF) of the activity of NR2B containing NMDARs (NR2B NMDARs) in the dorsal striatum. GRIN2B drug alcohol 17392475 Finally, dorsal but not ventral striatum infusion of a Fyn or NR2B NMDAR inhibitor reduced rat operant self administration of ethanol. GRIN2B addiction reward 17392475 Finally, dorsal but not ventral striatum infusion of a Fyn or NR2B NMDAR inhibitor reduced rat operant self administration of ethanol. GRIN2B drug alcohol 17392475 Our results suggest that the Fyn mediated phosphorylation and LTF of NR2B NMDAR activity in the dorsal striatum after exposure to ethanol may underlie aberrant plasticity that contributes to mechanisms underlying alcohol drinking behavior. GRIN2B drug alcohol 17229098 These observations support a model in which chronic ethanol exposure induces homeostatic increases of NR2B containing NMDA receptors and PSD 95 to the postsynaptic density. GRIN2B drug alcohol 17156796 Changes in function of NMDA receptor NR2B subunit in spinal cord of rats with neuropathy following chronic ethanol consumption. GRIN2B drug alcohol 17156796 Under these conditions, mRNA and protein levels of NR1, NR2A and NR2B subunits did not change in the spinal cord of chronic ethanol fed rats. GRIN2B drug alcohol 17156796 Interestingly, phosphorylated Ser 1303 NR2B (p Ser1303 NR2B) subunit was significantly increased in the spinal cord of chronic ethanol fed rats, whereas p Tyr1472 NR2B was not affected in the superficial spinal dorsal horn of ethanol fed rats. GRIN2B drug alcohol 17156796 These findings suggest that spinal p Ser1303 NR2B plays a significant role in the development of the ethanol dependent neuropathic pain like state in rats.

GRIN2B drug cocaine 16914681 Accordingly, NMDAR mediated EPSC decay time kinetics were significantly slower after cocaine, suggesting an increased number of NR2B containing NMDARs. GRIN2B drug cocaine 16914681 Together, our data suggest that acute cocaine increases NMDAR function in the VTA via activation of the cAMP/PKA pathway mediated by a DA D5 like receptor, leading to the insertion of NR2B containing NMDARs in the membrane. GRIN2B drug opioid 16859831 Our results demonstrate that NR2B selective conantokins, viz., con G, con G[S(16)Y] and con G[gamma(7)K], are potent inhibitors of naloxone induced jumping at low doses (2 15 nmol/kg) compared with con T, con R[1 17], and small molecule antagonists of the NMDAR, including the NR2B selective agent, ifenprodil. GRIN2B addiction dependence 16859831 We conclude that the NR2B selective conantokins may find utility as neuropharmacological tools for probing NMDAR related mechanisms of opiate dependence. GRIN2B addiction withdrawal 16839855 CIE treatment caused a relatively higher increase in NR2B protein, and this was the only sustained increase after long term withdrawal.

GRIN2B addiction sensitization 16794574 Reversal of cocaine induced behavioral sensitization and associated phosphorylation of the NR2B and GluR1 subunits of the NMDA and AMPA receptors. GRIN2B addiction sensitization 16794574 Sensitization was associated with increased NR2B expression in the accumbens (NAc) shell and decreased Tyr1472 phosphorylation in the NAc core, as well as increased Ser845 phosphorylation of the GluR1 subunit in prefrontal cortex, NAc core, and shell. GRIN2B drug opioid 16631172 The role of NR2B containing NMDA receptor in place preference conditioned with morphine and natural reinforcers in rats. GRIN2B drug opioid 16631172 Experimental results showed that (1) an augmented expression of NR2B subunit was revealed by Western blotting in the nucleus accumbens (NAc) and the hippocampus in rats with CPP induced by morphine, but not by natural rewards such as food, novel environment and social interaction.

GRIN2B drug opioid 16631172 Taking together, these findings suggested that NR2B containing NMDA receptor may be more involved with morphine reward rather than natural rewards, and that antagonism of NR2B may have a potential for the treatment of morphine abuse.

GRIN2B addiction withdrawal 16616767 Importantly, the opiate withdrawal induced increase in GluR2/3 was dependent on the activation of glucocorticoid receptors and NMDA receptors, as it was prevented by the glucocorticoid receptor antagonist RU38486, or intrahippocampal injection of the NMDA receptor antagonist AP 5 or the antagonist to NR2B containing NMDA receptors, Ro25 6981.

GRIN2B drug opioid 16453311 In this study we examined the effects of chronic morphine administration on gene and protein expression of three major NMDA receptors subunits (NR1, NR2A, and NR2B) in NAcc and CeA. GRIN2B drug opioid 16453311 However, at the protein level, immunoblotting revealed that chronic morphine significantly increased levels of NR1 and NR2B subunits. GRIN2B drug alcohol 16396741 Chronic ethanol exposure did not affect protein levels of the NR1 and NR2B subunits. GRIN2B drug alcohol 16179537 The increase in NMDA receptor number in response to chronic ethanol exposure both in vivo and in vitro is accompanied by an increase in NMDAR1 and NMDAR2B polypeptide levels. GRIN2B drug opioid 16117034 It is shown that NMDA receptor antagonists and specific diets able to negatively modulate NR2B subunit containing NMDA receptors prevented abnormal pain hypersensitivity, partially reversed chronic pain and restored the opioid effectiveness on opioid resistant pain models. GRIN2B addiction withdrawal 16052244 At 1 week withdrawal, mRNA levels for NR1 and NR2B subunits were significantly decreased. GRIN2B drug alcohol 16009711 Here we show that exposure of hippocampal neurons to ethanol increases the internalization of the NR2A but not NR2B subunit of the NMDAR via the endocytic pathway. GRIN2B drug alcohol 16009711 Importantly, ethanol treatment alters functional subunit composition from NR2A/NR2B to mainly NR2B containing NMDARs. GRIN2B drug alcohol 16009352 The ethanol sensitive NMDA receptor subunits NR1, NR2A and NR2B were quantified by Western immunoblot analysis. GRIN2B drug alcohol 16009352 Exposure to ethanol (50 mM) caused an increase in the levels of NR1 (137 +/ 11% of untreated control, P = 0.009), NR2A (128 +/ 14%, P = 0.022) and NR2B (136 +/ 19%, P = 0.012). GRIN2B drug alcohol 16009352 Coincubation with memantine (10 microM) completely blocked the ethanol induced up regulation of NR1 (102 +/ 4%), NR2A (95 +/ 7%) and NR2B (105 +/ 13%). GRIN2B drug cocaine 15953359 In the basolateral amygdala, GluR1 but not GluR2 levels were increased on days 1 and 30, NR2A levels were increased on day 1, and NR2B levels were decreased on day 30 of withdrawal from cocaine.

GRIN2B drug cocaine 15953359 In the central amygdala, GluR2 but not GluR1 levels were increased on days 1 and 30, NR1 levels were increased on day 30 and NR2A or NR2B levels were not altered after withdrawal from cocaine.

GRIN2B addiction withdrawal 15919065 Western blot analysis of NMDA receptor subunit expression showed that, at 7 days of withdrawal, the level of protein for NR2A and NR2B subunits was elevated in the CA1 region of hippocampal slices from CIE treated animals compared with slices from age matched controls. GRIN2B drug alcohol 15829254 In a comprehensive fashion, we studied dose response curves, employing the following selective pharmacological agents: the NMDAR competitive antagonist CGP37849, the glycine binding site antagonist L 701.324, the NR2B subunit selective antagonist ifenprodil, which acts at the polyamine binding site, the NMDAR channel blocker neramexane, and ethanol, which acts as a functional antagonist at the NMDAR.

GRIN2B drug alcohol 15542698 PCR based assays showed that alcoholism was associated with polymorphisms of the dopamine D2 receptor (DRD2) TaqI B (P = .029) and the GABAA beta2 subunit C1412T (P = .012) genes, but not with the glutamate receptor subunit gene NMDAR2B (366C/G), the serotonin transporter gene (5HTTL PR), the dopamine transporter gene DAT1(SLC6A3), the dopamine D2 receptor gene DRD2 TaqI A, or the GABAA alpha1(A15G), alpha6(T1519C), and gamma2(G3145A) subunit genes.

GRIN2B drug opioid 15263066 Taken together with our recent molecular studies, our data are consistent with a shift away from NMDA receptor subunit (NR) NR2B and 2C function toward increased NR2A subunit expression or function after chronic morphine, a process that could alter excitability and integrative properties and may represent a neuroadaptation of NAcc medium spiny neurons underlying morphine dependence.

GRIN2B drug alcohol 15180478 Our results showed that especially the NR2B subunit expression is increased in cultured hippocampal and cortical neurones after 3 days of intermittent ethanol treatment. GRIN2B drug alcohol 15180478 According to the high calcium permeability, the increased agonist sensitivity and the relatively slow closing kinetics of NMDA ion channels composed of NR2B subunits, the above mentioned changes may underlie the enhanced NMDA receptor activation observed after long term ethanol exposure. GRIN2B drug alcohol 15180478 Accordingly, we have tested NR2B subunit selective NMDA receptor antagonists in primary cultures of rat cortical neurones pre treated with ethanol intermittently for 3 days and found that these compounds potently inhibited the neurotoxic effect of ethanol withdrawal.

GRIN2B drug alcohol 15180478 The aim of this review is to give an update on the role of altered structure and function of NMDA receptors after ethanol exposure and to summarise the recent data about the activity of NR2B subunit selective NMDA receptor antagonists in model systems related to alcoholism. GRIN2B drug opioid 15157688 In contrast, the polyamine (NR2B) site antagonist, Ro 25 6981, attenuated morphine analgesia at all doses. GRIN2B drug opioid 15157688 Strikingly, the non competitive antagonists produced no modulation of morphine analgesia whatsoever in female mice, whereas no sex differences were observed using competitive or NR2B antagonists. GRIN2B addiction withdrawal 15057640 Recently emerged NR2B SSNAs (CP 101606 (Pfizer Inc), Co 101244 (Pfizer Inc/Purdue Neuroscience Corp/Senju Pharmaceutical Co Ltd), CI 1041 (Purdue Neuroscience Corp/Pfizer Inc) and indole 2 carboxamide derivatives) have demonstrated excellent in vitro potency against withdrawal induced cytotoxicity. GRIN2B drug alcohol 15057640 Although in vivo data are few, according to their in vitro efficacy and good tolerability, novel NMDA antagonists, especially the NR2B selective antagonists, may offer a preferable alternative to the presently available pharmacotherapies for treating alcoholism. GRIN2B drug alcohol 14973247 Ifenprodil also occluded the ethanol effect, suggesting that NR2B subunit containing receptors may be involved. GRIN2B drug alcohol 14684447 Preliminary studies with microdialysis and real time PCR analysis support this idea: local ethanol administration in vivo had no effect on glutamate release, but chronic ethanol nearly tripled the expression of NR2B subunits (the most ethanol sensitive) in CeA. GRIN2B drug alcohol 14634488 Fyn kinase and NR2B containing NMDA receptors regulate acute ethanol sensitivity but not ethanol intake or conditioned reward. GRIN2B addiction reward 14634488 Fyn kinase and NR2B containing NMDA receptors regulate acute ethanol sensitivity but not ethanol intake or conditioned reward. GRIN2B drug alcohol 14634488 Recently, we found that the compartmentalization of Fyn to the NR2B subunit of the NMDA receptor (NMDAR) in the hippocampus regulates Fyn phosphorylation of NR2B in response to ethanol, which mediates the acute tolerance of NMDAR to ethanol inhibition in hippocampal slices. GRIN2B drug alcohol 14634488 In this study we determined, first, whether acute tolerance to ethanol inhibition is mediated via NR2B containing NMDARs in vivo and, second, whether the increase in acute sensitivity to ethanol in the Fyn / mice influences ethanol consumption or ethanol's conditioned rewarding effects. GRIN2B drug alcohol 14634488 We found that systemic injection of the NR2B containing NMDAR selective antagonist, ifenprodil, abolished the differences between Fyn+/+ and Fyn / mice in sensitivity to the acute sedative effects of ethanol. GRIN2B drug alcohol 14634488 Our results suggest that the interaction between Fyn and NR2B mediates the acute sedative effects of ethanol, and that alteration in acute ethanol sensitivity does not necessarily correlate with levels of ethanol consumption or the rewarding properties of ethanol. GRIN2B drug alcohol 14634487 Polypeptide levels of mGluR5s and the NR1 and NR2B subunits of NMDARs were also determined via Western blot analyses after 10 days of ethanol exposure. GRIN2B drug alcohol 14634487 The polypeptide levels of mGluR5s and NR1 and NR2B subunits of NMDARs were all increased after ethanol exposure; however, the increase in mGluR5s did not achieve statistical significance. GRIN2B drug alcohol 14573320 Genotyping of the NMDAR2B polymorphism revealed a significantly reduced T allele in Cloninger type 2 alcoholics and in patients reporting an early onset compared with control subjects. GRIN2B drug alcohol 14534353 These findings suggest that NR2B containing receptors may be specifically enhanced and suggest that processes dependent upon calcium influx through amygdala NMDA receptors may potentially be enhanced by chronic ethanol ingestion. GRIN2B drug alcohol 14534353 Most GAD , presumed projection neurons expressed both NR2A and NR2B mRNAs, and this profile did not change during chronic ethanol exposure.

GRIN2B drug cocaine 11801363 Moreover, we observed that rats sensitized to cocaine presented a significant increase in the levels of GLUR1, NR1 and NR2B, in the nucleus accumbens, and of NR2B in the hippocampus compared to control animals. GRIN2B drug alcohol 11696675 Unexpectedly, we found that expression of NR1 (including the expression of NR1 subunits containing the N1, C1, and C2 inserts), NR2A, NR2B, NR2C, GluR1, GluR2/3, GluR5, GluR6/7, and KA2 subunits was not altered in hippocampal homogenates from ethanol exposed rats. GRIN2B drug alcohol 11530236 Ethanol inhibition of the CA1 NR2B mediated component was five to seven times lower in NR2A(DeltaC/DeltaC) than in C57Bl/6. GRIN2B drug alcohol 11530236 The altered sensitivities to ethanol of both NR2A and NR2B mediated responses in the CA1 of NR2A(DeltaC/DeltaC) imply that NR2A and NR2B subunit containing NMDA receptors may be linked by a common target of ethanol. GRIN2B drug alcohol 11369029 In HEK 293 cells, acamprosate showed almost no effect on NR1 1a/NR2A or NR1 1a/NR2B recombinants (IC(50)s not calculated). GRIN2B drug opioid 11233291 treatment with a specific antibody against the carboxyl terminal region of the NR2B subunit abolishes the morphine induced place preference, whereas antibodies against the NR1 and NR2A subunits do not affect the rewarding effect of morphine, indicating that the blockade of the NR2B subunit suppresses the development of the morphine induced rewarding effect.

GRIN2B drug opioid 9988122 Using in situ hybridization techniques, the effects of chronic morphine treatment on the expression of mRNAs encoding the NMDA receptor subunits NRI, NR2A, and NR2B were investigated. GRIN2B drug opioid 9988122 The expression of NR2A and NR2B subunit mRNAs did not change after morphine treatment in any brain region. GRIN2B drug alcohol 9765326 In situ hybridization studies suggest that expression of NR2B subunit mRNA may be enhanced in explants after chronic ethanol exposure. GRIN2B drug alcohol 9756034 Recent research has focused on the N methyl D aspartate receptor system as a major site of ethanol action in the brain and specifically on compensatory changes in the expression of the polyamine sensitive NR2B subunit.

GRIN2B addiction withdrawal 9685652 We investigated the effect of chronic ethanol administration and its withdrawal on the polypeptide levels of NMDA receptor subunits such as NR1, NR2A, and NR2B in the rat cerebral cortex and hippocampus using Western blot analysis technique. GRIN2B drug alcohol 9685652 Our results indicate that chronic ethanol treatment upregulates NMDA receptor subunits NR1, NR2A, and NR2B (approximately 35%). GRIN2B drug alcohol 9670216 The sensitivity of NMDA receptors to ethanol block is proposed to involve the NMDAR2B subunit in certain brain regions, but this subunit does not appear to be the sole determinant of this interaction. GRIN2B drug alcohol 9670216 Tolerance to ethanol results in enhanced EAA neurotransmission and NMDA receptor upregulation, which appears to involve selective increases in NMDAR2B subunit levels and other molecular changes in specific brain loci.

GRIN2B drug alcohol 9145911 Immunoblot analysis of expression of NR1, NR2A, and NR2B receptor subunits showed no difference between control and chronic ethanol treated cultures. GRIN2B drug alcohol 8912402 Furthermore, since there is evidence that eliprodil produces its pharmacological actions through a specific inhibition of NMDAR1 and/or NMDAR2B subunits, these data may indicate that certain NMDA receptor subunits may be of particular importance for the mediation of seizure activity following the discontinuation of chronic ethanol exposure. CYP2E1 drug alcohol 32724497 These results indicate that MANF has potential protection on alcohol induced liver injury, and the underlying mechanisms may be associated with meliorating the overactivated ER stress triggered by inflammation and oxidative stress via inhibiting and reducing NO/NF κB and CYP2E1/ROS, respectively.

CYP2E1 drug alcohol 25162931 Cytochrome P4502E1 (CYP2E1) has been demonstrated to play crucial roles in chronic ethanol induced fatty liver, while its role in acute ethanol induced fatty liver remains unclear. CYP2E1 drug alcohol 25162931 The current study was designed to evaluate the effects of chlormethiazole (CMZ), a specific inhibitor of CYP2E1, on acute ethanol induced fatty liver, and to explore the mechanisms. CYP2E1 drug alcohol 25162931 Collectively, the results of the current study demonstrated that CMZ could effectively attenuate acute ethanol induced fatty liver possibly by suppressing oxidative stress and adiponectin decline, and activating autophagy, which suggest that CYP2E1 might also play important roles in acute ethanol induced fatty liver. CYP2E1 drug alcohol 24618581 Depolarization was linked to ethanol metabolism, since deficiency of alcohol dehydrogenase and cytochrome P450 2E1 (CYP2E1), the major ethanol metabolizing enzymes, decreased mitochondrial depolarization by ∼ 70% and ∼ 20%, respectively. CYP2E1 drug alcohol 24481563 The data indicate an increased susceptibility of fatty liver to ethanol and suggest that the synergistic effect of diet and ethanol on lipid dysmetabolism might be mediated, at least in part, by PPARs and cytochromes CYP4A1 and CYP2E1.

CYP2E1 drug alcohol 23400924 Catalase and cytochrome P450 2E1 (CYP2E1) represent the major enzymes in the CNS that catalyze ethanol oxidation. CYP2E1 drug alcohol 23400924 This chapter focuses on the discussion of CYP2E1 in ethanol metabolism in the CNS, covering topics including how it is regulated, where it is expressed and how it influences sensitivity to ethanol in the brain. CYP2E1 drug alcohol 23363738 An existing inhibitor of CYP2E1 is the drug disulfiram. CYP2E1 drug alcohol 23363738 Disulfiram inhibits CYP2E1 at conventional therapeutic dosages and increases blood acetone levels in humans and animals. CYP2E1 drug alcohol 23352848 However, sodium azide, a catalase inhibitor, and allyl sulfide, an inhibitor of cytochrome P450 2E1 (CYP2E1), failed to overcome LTP inhibition by 60mM ethanol. CYP2E1 drug alcohol 23118795 In addition; levels of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), the activities of cytochrome P450 2E1 (CYP2E1), selected antioxidative enzymes, and the contents of malonaldehyde (MDA) were measured.

CYP2E1 addiction intoxication 22819980 Inhibition of macroautophagy by administration of 3 methyladenine enhanced the binge ethanol hepatotoxicity, steatosis and oxidant stress in CYP2E1 KI, but not CYP2E1 KO mice. CYP2E1 drug alcohol 22819980 Treatment of HepG2 E47 cells which express CYP2E1 with 100mM ethanol for 8 days increased fat accumulation and oxidant stress but decreased autophagy.

CYP2E1 addiction intoxication 22819980 Inhibition of autophagy promotes binge ethanol induced hepatotoxicity, steatosis and oxidant stress via CYP2E1. CYP2E1 drug alcohol 22749809 Recent studies showed that chronic ethanol induced fatty liver was, at least in part, CYP2E1 dependent. CYP2E1 drug alcohol 22749809 The mechanism of acute alcohol induced steatosis and whether CYP2E1 plays any role are still unclear. CYP2E1 drug alcohol 22749809 We used CYP2E1 knockout (KO) mice, a JNK inhibitor, and JNK1 or JNK2 knockout mice to test the role of CYP2E1, JNK, and the individual role of JNK1 and JNK2 in acute alcohol induced steatosis. CYP2E1 drug alcohol 22749809 In wild type (WT) mice, acute alcohol activates CYP2E1 and increases oxidative stress, which reciprocally increases activation of the JNK signaling pathway. CYP2E1 drug alcohol 22749809 Acute alcohol induced fatty liver and oxidative stress were blunted in CYP2E1 KO mice and by the JNK inhibitor in WT mice. CYP2E1 drug alcohol 22749809 The antioxidant N acetylcysteine decreased the acute alcohol induced oxidative stress, the activation of JNK, and the steatosis but not the activation of CYP2E1. CYP2E1 drug alcohol 22749809 The results show that acute alcohol elevation of CYP2E1, oxidative stress, and activation of JNK interact to lower autophagy and increase lipogenic SREBP resulting in fatty liver. CYP2E1 drug alcohol 22577853 Nine hundred fifty single nucleotide polymorphisms (SNPs) spanning 14 genes (ACN9, ACSS1, ACSS2, ALDH1A1, CAT, CYP2E1, GOT1, GOT2, MDH1, MDH2, SLC25A10, SLC25A11, SLC25A12, SLC25A13) were genotyped in 352 young adults who participated in an alcohol challenge study. CYP2E1 drug alcohol 22577853 However, based on the breath alcohol data, variation in the promoter of CYP2E1 may play a role in preabsorptive or early hepatic alcohol metabolism, but more samples are required to validate this finding. CYP2E1 drug alcohol 22552773 Ethanol induction of CYP2A5: role of CYP2E1 ROS Nrf2 pathway. CYP2E1 drug alcohol 22552773 Chronic ethanol consumption was previously shown to induce CYP2A5 in mice, and this induction of CYP2A5 by ethanol was CYP2E1 dependent. CYP2E1 drug alcohol 22552773 In this study, the mechanisms of CYP2E1 dependent ethanol induction of CYP2A5 were investigated. CYP2E1 drug alcohol 22552773 CYP2E1 was induced by chronic ethanol consumption to the same degree in wild type (WT) mice and CYP2A5 knockout (Cyp2a5 ( / )) mice, suggesting that unlike the CYP2E1 dependent ethanol induction of CYP2A5, ethanol induction of CYP2E1 is not CYP2A5 dependent. CYP2E1 drug alcohol 22552773 Microsomal ethanol oxidation was about 25% lower in Cyp2a5 ( / ) mice compared with that in WT mice, suggesting that CYP2A5 can oxidize ethanol although to a lesser extent than CYP2E1 does. CYP2E1 drug alcohol 22552773 CYP2A5 was induced by short term ethanol consumption in human CYP2E1 transgenic knockin (Cyp2e1 ( / ) KI) mice but not in CYP2E1 knockout (Cyp2e1 ( / )) mice. CYP2E1 drug alcohol 22552773 The redox sensitive transcription factor nuclear factor erythroid 2 related factor 2 (Nrf2) was also induced by acute ethanol in Cyp2e1 ( / ) KI mice but not in Cyp2e1 ( / ) mice. CYP2E1 drug alcohol 22552773 Ethanol induction of CYP2A5 in Nrf2 knockout (Nrf2 ( / )) mice was lower compared with that in WT mice, whereas CYP2E1 induction by ethanol was comparable in WT and Nrf2 ( / ) mice. CYP2E1 drug alcohol 22552773 Antioxidants (N acetyl cysteine and vitamin C), which blocked oxidative stress induced by chronic ethanol in WT mice and acute ethanol in Cyp2e1 ( / ) KI mice, also blunted the induction of CYP2A5 and Nrf2 by ethanol but not the induction of CYP2E1 by ethanol. CYP2E1 drug alcohol 22552773 These results suggest that oxidative stress induced by ethanol via induction of CYP2E1 upregulates Nrf2 activity, which in turn regulates ethanol induction of CYP2A5. CYP2E1 drug alcohol 22545783 The significant changes in proteome profile in chronic ethanol binge were accompanied by a marked increase in liver injury as evidenced by enhanced steatosis, necrosis, increased 4 hydroxynonenal labeled proteins, CYP2E1 expression, and decreased histone H2AX phosphorylation.

CYP2E1 drug alcohol 21284674 Exposing 4 dpf zebrafish larvae to 2% ethanol (EtOH) for 32 hours achieves ∼80 mM intracellular EtOH and upregulation of hepatic cyp2e1, sod, and bip, indicating that EtOH is metabolized and provokes oxidative stress. CYP2E1 drug alcohol 20958327 The inhibitor of cytochrome P450 2E1 (CYP2E1) had no effect on ethanol induced DNA damage, and CYP2E1 mRNA expression was not affected by ethanol. CYP2E1 drug alcohol 20828554 The ethanol elimination rate is regulated by alcohol metabolizing enzymes, primarily alcohol dehydrogenase (ADH1), acetaldehyde dehydrogenase (ALDH), and cytochrome P450 (CYP2E1). CYP2E1 drug alcohol 20598484 The most well known metabolic pathways from ethanol to acetaldehyde include alcohol dehydrogenase (ADH) and the microsomal ethanol oxidizing system that involves cytochrome P450 2E1 (CYP2E1).

CYP2E1 drug alcohol 20401433 The purpose of this study was to investigate the differences, if present, in the allele and genotype frequency of alcohol dehydrogenase 1B (ADH1B), ADH1C and the microsomal ethanol oxidizing system (MEOS/CYP2E1) between alcohol dependent individuals and controls and also to determine if these genotypes cause a difference in the age at which the patients become alcohol dependent. CYP2E1 drug alcohol 20401433 The allele and genotype frequencies of ADH1B, ADH1C, and CYP2E1 were determined in 204 alcohol dependent men and 172 healthy volunteers who do not drink alcohol (control group). CYP2E1 drug alcohol 20401433 The persons with ADH1C*1/*1 and CYP2E1*c1/*c2 genotypes became alcohol dependent at a considerably younger age than the subjects with ADH1C*1/*2, ADH1C*2/*2 and CYP2E1*c1/*c1 genotypes (28.08, 25.67 years vs 36.0, 45.05, 34.45 years, respectively).

CYP2E1 drug alcohol 20304569 In alcoholics during detoxification, because activity of microsomal enzyme (CYP2E1) is boosted, the ethanol elimination rate might be 25 35 mg/100mL/h.

CYP2E1 drug alcohol 19079654 Ethanol, alone and in high concentrations, was found to greatly affect cell function as shown by decreased cellular ATP levels, increased LDH release, and a downregulated expression of CYP2E1 gene. CYP2E1 addiction addiction 19004845 Published data and data obtained from the drug's manufacturer implies that the dose escalation after 48 hours is to compensate for fomepizole induced increased body clearance resulting from autoinduction of the cytochrome P450 (CYP) drug metabolizing enzyme CYP2E1. CYP2E1 drug alcohol 18804449 Use of CYP2E1 knockout mice demonstrated that ethanol induced acetylation was not dependent solely on CYP2E1 expression.

CYP2E1 drug alcohol 17718403 The primary enzymes involved are aldehyde dehydrogenase (ALDH), alcohol dehydrogenase (ADH), cytochrome P450 (CYP2E1), and catalase. CYP2E1 drug alcohol 17590863 The presence in rat mammary tissue of low activities of additional enzymes able to generate acetaldehyde was established (alcohol dehydrogenase: 0.97+/ 0.84 mU mg( 1) protein; CYP2E1: 1.30+/ 0.12 x 10( 2) pmol 4 nitrocatechol min( 1) mg( 1) protein) and a low activity of aldehyde dehydrogenase was observed in the cytosolic, mitochondrial and microsomal fractions (0.02+/ 0.04; 0.35+/ 0.09 and 0.72+/ 0.19 mU mg( 1) protein, respectively). CYP2E1 drug alcohol 17392391 Role of CYP3A and CYP2E1 in alcohol mediated increases in acetaminophen hepatotoxicity: comparison of wild type and Cyp2e1( / ) mice. CYP2E1 drug alcohol 17392391 CYP2E1 is widely accepted as the sole form of cytochrome P450 responsible for alcohol mediated increases in acetaminophen (APAP) hepatotoxicity. CYP2E1 drug alcohol 17392391 However, we previously found that alcohol [ethanol and isopentanol (EIP)] causes increases in APAP hepatotoxicity in Cyp2e1( / ) mice, indicating that CYP2E1 is not essential. CYP2E1 drug alcohol 17392391 At the time of APAP administration, which followed an 11 h withdrawal from the alcohols, alcohol induced levels of CYP3A were sustained in both mouse lines, whereas CYP2E1 was decreased to constitutive levels in wild type mice. CYP2E1 addiction withdrawal 17392391 At the time of APAP administration, which followed an 11 h withdrawal from the alcohols, alcohol induced levels of CYP3A were sustained in both mouse lines, whereas CYP2E1 was decreased to constitutive levels in wild type mice. CYP2E1 drug alcohol 17392391 In conclusion, these findings suggest that both CYP3A and CYP2E1 contribute to APAP hepatotoxicity in alcohol treated mice. CYP2E1 drug alcohol 17058263 Binge or chronic alcohol exposure significantly elevated nitric oxide, inducible nitric oxide synthase, and ethanol inducible CYP2E1. CYP2E1 addiction intoxication 17058263 Binge or chronic alcohol exposure significantly elevated nitric oxide, inducible nitric oxide synthase, and ethanol inducible CYP2E1. CYP2E1 drug alcohol 16923312 Furthermore, hydroxyethyl free radicals (HER) are also generated during ethanol metabolism by CYP2E1. CYP2E1 addiction sensitization 16549397 In order to evaluate the biochemical and toxicological actions of CYP2E1 and its sensitization of hepatotoxin induced injury, an adenovirus which can mediate overexpression of CYP2E1 was constructed. CYP2E1 drug alcohol 16337880 CYP2E1 plays an important role in toxicity of many chemicals and ethanol and produces oxidant stress. CYP2E1 addiction withdrawal 16337880 Serum withdrawal induced E47 cell death could be rescued by antioxidants, the mitochondrial permeability transition inhibitor cyclosporine A, z DEVD fmk, and a CYP2E1 inhibitor 4 methylpyrazole. CYP2E1 addiction withdrawal 16337880 We propose that the mechanism of this serum withdrawal plus CYP2E1 toxicity involves increased production of intracellular ROS, lipid peroxidation, and decline of GSH levels, which results in mitochondrial membrane damage and loss of membrane potential, followed by apoptosis. CYP2E1 drug alcohol 16337880 Potentiation of serum deprivation induced cell death by CYP2E1 may contribute to the sensitivity of the liver to alcohol induced ischemia and growth factor deprivation. CYP2E1 drug alcohol 16337197 In this study, we asked whether ethanol, a known inducer of microsomal CYP2E1, could also increase CYP2E1 within mitochondria. CYP2E1 drug alcohol 16337197 Our findings indicated that ethanol increased microsomal and mitochondrial CYP2E1 in cultured rat hepatocytes and in the liver of lean mice. CYP2E1 drug alcohol 16337197 In contrast, in leptin deficient obese mice, ethanol administration did not increase mitochondrial CYP2E1, nor it depleted mitochondrial glutathione, suggesting that leptin deficiency hampers mitochondrial targeting of CYP2E1. CYP2E1 drug alcohol 16337197 Thus, ethanol intoxication increases CYP2E1 not only in the endoplasmic reticulum but also in mitochondria, thus favouring oxidative stress in these compartments. CYP2E1 addiction intoxication 16337197 Thus, ethanol intoxication increases CYP2E1 not only in the endoplasmic reticulum but also in mitochondria, thus favouring oxidative stress in these compartments. CYP2E1 drug alcohol 16317704 Alcohol administration to ob/ob mice did not increase oxidative stress despite increased CYP2E1, but increased plasma TNF alpha, further increased Hsp70, and profoundly decreased p65 nuclear factor kappaB (NF kappaB) protein and DNA binding activity in nuclear extracts.

CYP2E1 drug alcohol 15982967 After 4 weeks of ethanol intoxication, although cytochrome CYP2E1 was increased, liver lipid peroxidation remained unchanged when protein carbonyls augmented selectively for high molecular weight with a decrease of the proteasome activities in ethanol rats. CYP2E1 addiction intoxication 15982967 After 4 weeks of ethanol intoxication, although cytochrome CYP2E1 was increased, liver lipid peroxidation remained unchanged when protein carbonyls augmented selectively for high molecular weight with a decrease of the proteasome activities in ethanol rats. CYP2E1 drug alcohol 15961886 Because cytochrome P4502E1 (CYP2E1) is upregulated in Kupffer cells after ethanol, we hypothesized that this effect primes Kupffer cells, sensitizing them to increase TNF alpha production in response to LPS. CYP2E1 addiction sensitization 15961886 Oxidant generation after CYP2E1 overexpression appears to be central to macrophage priming and their sensitization to LPS. CYP2E1 drug alcohol 15961886 Accordingly, CYP2E1 priming could explain the sensitization of Kupffer cells to LPS activation by ethanol, a critical early step in alcoholic liver disease. CYP2E1 addiction sensitization 15961886 Accordingly, CYP2E1 priming could explain the sensitization of Kupffer cells to LPS activation by ethanol, a critical early step in alcoholic liver disease. CYP2E1 drug alcohol 15066702 Mexican Americans have a low frequency of the protective alleles ADH1B(*)2 and ALDH2(*)2 and a relatively high frequency of CYP2E1 c2, which is associated with early onset alcoholism. CYP2E1 drug alcohol 14695664 Hepatitis C virus (HCV) and HCV core protein are hypothesized to induce hepatic oxidative stress and exacerbate injury caused by other toxins such as ethanol that induce the cytochrome P450 enzyme, CYP2E1. CYP2E1 addiction sensitization 14695664 These studies show simultaneous expression of HCV core protein and CYP2E1 increases parameters indicative of oxidative stress as well as sensitization to cell injury induced by GSH depletion.

CYP2E1 addiction dependence 12777962 Although the power of the association study was low among some subgroups, the CYP2E1*1D genotype (subjects with at least one variant allele) was associated with alcohol as well as nicotine dependence. CYP2E1 drug alcohol 12777962 Specifically, Canadian Native Indians dependent on nicotine alone or alcohol alone exhibited significantly greater CYP2E1*1D frequencies compared to non drug dependent controls, while the variant frequency among Southeast Asians dependent on nicotine was greater than their non drug dependent counterparts. CYP2E1 drug nicotine 12777962 Specifically, Canadian Native Indians dependent on nicotine alone or alcohol alone exhibited significantly greater CYP2E1*1D frequencies compared to non drug dependent controls, while the variant frequency among Southeast Asians dependent on nicotine was greater than their non drug dependent counterparts.

CYP2E1 drug alcohol 12710951 The ADH3*2 and CYP2E1 c2 alleles increase the risk of alcoholism in Mexican American men. CYP2E1 drug alcohol 12710951 To identify the association between the polymorphisms of genes encoding alcohol metabolizing enzymes and alcoholism, the alcohol dehydrogenase 2 (ADH2), alcohol dehydrogenase 3 (ADH3), aldehyde dehydrogenase 2 (ALDH2), and cytochrome P450 2E1 (CYP2E1) genes were studied in 101 male Mexican American alcoholics. CYP2E1 drug alcohol 12710951 Association was also found between the CYP2E1 RsaI c2 allele and alcohol dependence; the percentage of subjects who carry the RsaI c2 allele was significantly higher in alcoholics (34.7%) than in nonalcoholics (22.1%). CYP2E1 addiction dependence 12710951 Association was also found between the CYP2E1 RsaI c2 allele and alcohol dependence; the percentage of subjects who carry the RsaI c2 allele was significantly higher in alcoholics (34.7%) than in nonalcoholics (22.1%). CYP2E1 drug alcohol 12710951 The subjects whose alcohol drinking onset age is younger than 25 have much higher CYP2E1 c2 allele frequency than those whose alcohol drinking onset age is older than 25 (22.1% vs 15.7%). CYP2E1 drug alcohol 12710951 Among 101 alcoholics, only 18 subjects carry neither ADH3*2 nor CYP2E1 c2 alleles. CYP2E1 drug alcohol 12710951 For those subjects who have an ADH*1/*1 background, a strong association is found between CYP2E1 RsaI/DraI genotype and alcoholism; the CYP2E1 RsaI c2 and DraI C allele frequencies are much higher in alcoholics than in nonalcoholics (26.4% vs 9.6% for c2 and 27.8% vs 13.5% for C allele). CYP2E1 drug alcohol 12710951 Taken together, ADH3*2 and CYP2E1 c2/C alleles might independently contribute to the development of alcoholism in Mexican American men. CYP2E1 drug alcohol 12707490 CYP2E1 and clinical features in alcoholics. CYP2E1 drug alcohol 12707490 Persons who are either hetereozygous or mutant homozygous for CYP2E1 (C1/C2 or C2/C2) can drink much more alcohol than persons who are normal homozygous for CYP2E1 (C1/C1) among those whose aldehyde dehydrogenase 2 genotype is heterozygous. CYP2E1 drug alcohol 12707490 We have shown that the genotypes of CYP2E1 are associated with clinical features of alcoholics. CYP2E1 drug alcohol 12433812 Chronic ethanol consumption potentiates acetaminophen (APAP) hepatotoxicity through enhanced NAPQI formation via CYP2E1 induction and selective depletion of mitochondrial glutathione. CYP2E1 drug alcohol 12433812 The highest ethanol containing diet (36% energy as ethanol) was replaced by control diet for 2, 5, 12, and 17 h. Maximal CYP2E1 induction was caused by 36% energy as ethanol diet (2.2 fold, p < 0.05 versus control). CYP2E1 drug alcohol 12433812 In conclusion, high dose ethanol potentiated APAP hepatotoxicity via CYP2E1 induction and selective mitochondrial GSH depletion. CYP2E1 drug alcohol 11812920 The liver expresses many cytochrome P450 isoforms, including ethanol induced CYP2E1. CYP2E1 drug alcohol 11812920 CYP2E1 generates ROS, activates many toxicologically important substrates, and may be the central pathway by which ethanol causes oxidative stress. CYP2E1 drug alcohol 11804663 Chronic ethanol consumption results in the induction of hepatic cytochrome P4502E1 (CYP2E1) in man, which is believed to play an important role in the pathogenesis of alcoholic liver disease. CYP2E1 drug alcohol 11804663 However, the amount and duration of alcohol intake associated with CYP2E1 induction is not known but limited information is available on the disappearance of CYP2E1 following alcohol withdrawal. CYP2E1 addiction withdrawal 11804663 However, the amount and duration of alcohol intake associated with CYP2E1 induction is not known but limited information is available on the disappearance of CYP2E1 following alcohol withdrawal. CYP2E1 drug alcohol 11804663 CYP2E1 induction was monitored by using the chlorzoxazone test before and every week following the start of alcohol ingestion. CYP2E1 drug alcohol 11804663 In addition, CYP2E1 was also determined in five alcoholics 1, 3, 8 and 15 days following ethanol withdrawal and in five patients with non alcoholic liver disease. CYP2E1 addiction withdrawal 11804663 In addition, CYP2E1 was also determined in five alcoholics 1, 3, 8 and 15 days following ethanol withdrawal and in five patients with non alcoholic liver disease. CYP2E1 drug alcohol 11804663 A significant CYP2E1 induction occurred 1 week following the ingestion of 40 g ethanol per day and increased further after 4 weeks. CYP2E1 drug alcohol 11804663 The disappearance of CYP2E1 was found to be significant 3 days following ethanol withdrawal and further decreased up to day 8. CYP2E1 addiction withdrawal 11804663 The disappearance of CYP2E1 was found to be significant 3 days following ethanol withdrawal and further decreased up to day 8. CYP2E1 drug alcohol 11804663 Thereafter, no significant change occurred and CYP2E1 activities were comparable with those in patients with non alcoholic liver disease. CYP2E1 drug alcohol 11804663 These data show a significant and quick induction of CYP2E1 activity, already at moderate alcohol consumption, which may be of importance in the pathogenesis of alcoholic liver disease, of ethanol, drug and vitamin A interactions and in alcohol associated carcinogenesis. CYP2E1 drug alcohol 11762131 Cytochrome P450 2E1 (CYP2E1) is the key enzyme of the microsomal pathway of ethanol oxidation. CYP2E1 drug alcohol 11762131 Therefore, heavy consumption of alcohol, which results in CYP2E1 induction, increases individual susceptibility to the toxic or carcinogenic effects of these xenobiotics. CYP2E1 drug alcohol 11755313 Ethanol withdrawal induced CYP2E1 degradation in vivo, blocked by proteasomal inhibitor PS 341. CYP2E1 addiction withdrawal 11755313 Ethanol withdrawal induced CYP2E1 degradation in vivo, blocked by proteasomal inhibitor PS 341. CYP2E1 drug alcohol 11755313 Previously, only in vitro evidence showed that CYP2E1 induced by ethanol is degraded by the proteasome. CYP2E1 drug alcohol 11755313 Ethanol treatment induced a 3 fold increase in CYP2E1 levels determined by Western blot. CYP2E1 drug alcohol 11755313 When ethanol was withdrawn, CYP2E1 decreased to control levels. CYP2E1 drug alcohol 11755313 In ethanol withdrawn rats injected with PS 341, CYP2E1 remained at the induced level. CYP2E1 drug alcohol 11755313 These results show, for the first time, that the proteasome is responsible for ethanol induced CYP2E1 degradation in vivo. CYP2E1 drug alcohol 11398342 The cytochrome P450 2E1 (CYP2E1) gene, which is mapped to chromosome 10q24.3 qter contributes also the conversion of ethanol to acetaldehyde. CYP2E1 drug alcohol 11391053 The presentations were (1) Mutations in the exons, exon intron junctions, and promoter regions of human CYP2E1 gene and alcoholism, by Fumio Nomura; (2) Genetic variability in alcohol metabolism and drinking habits in Japanese, by Shoji Harada; (3) Genetic studies of alcohol dependence using alcoholics with inactive ALDH2, by Susumu Higuchi; and (4) Alcohol consumption, apolipoprotein polymorphisms, and cardiovascular disorders, by Dharam P. Agarwal.

Agarwal. CYP2E1 drug alcohol 11236836 We evaluated the role of three polymorphic genes related to alcohol metabolism (CYP2E1) and, possibly, dependence (DRD2 and SLC6A4 promoter) in a series of 60 alcoholics admitted to a specialized referral center in Florence, Italy. CYP2E1 addiction dependence 11236836 We evaluated the role of three polymorphic genes related to alcohol metabolism (CYP2E1) and, possibly, dependence (DRD2 and SLC6A4 promoter) in a series of 60 alcoholics admitted to a specialized referral center in Florence, Italy. CYP2E1 drug alcohol 11236836 No difference was found in the frequency of the CYP2E1 Rsal c2 allele (2.5% among alcoholics and 4.7% among controls) and the DraI C allele (6.7% and 10.1%). CYP2E1 drug alcohol 11173972 The intragastric alcohol infusion rat model (IAIRM) of alcoholic liver disease (ALD) has been utilized in various laboratories to study various aspects of ALD pathogenesis including oxidative stress, cytokine upregulation, hypoxic damage, apoptosis, ubiquitin proteasome pathway and CYP2E1 induction. CYP2E1 drug alcohol 10964266 Since treatment of experimental alcoholic liver disease with CYP2E1 inhibitors had an ameliorating effect on liver injury in the rat, chlormethiazole was used to see if it had a similar effect. CYP2E1 drug alcohol 10964266 The CYP2E1 apoprotein levels, which were increased by ethanol feeding, were also increased when chlormethiazole was fed with ethanol. CYP2E1 drug alcohol 10964266 Chlormethiazole inhibited the increase in the ethanol induced CYP2E1 activity in vivo, as measured by chlorzoxazone 6 hydroxylation, but did not affect the level of CYP2E1 apoprotein. CYP2E1 drug alcohol 10759684 In animals, chronic ethanol causes induction of hepatic microsomal enzymes and increases paracetamol hepatotoxicity as expected (ethanol primarily induces CYP2E1 and this isoform is important in the oxidative metabolism of paracetamol). CYP2E1 drug alcohol 10759684 However, in man, chronic alcohol ingestion causes only modest (about twofold) and short lived induction of CYP2E1, and there is no corresponding increase (as claimed) in the toxic metabolic activation of paracetamol. CYP2E1 drug alcohol 10759684 The paracetamol ethanol interaction is not specific for any one isoform of cytochrome P450, and it seems that isoenzymes other than CYP2E1 are primarily responsible for the oxidative metabolism of paracetamol in man. CYP2E1 drug alcohol 10456581 Two days following alcohol withdrawal, the apparent activity of the alcohol inducible form of cytochrome P450 (CYP2E1) was unchanged although total cytochrome P450 content was increased. CYP2E1 addiction withdrawal 10456581 Two days following alcohol withdrawal, the apparent activity of the alcohol inducible form of cytochrome P450 (CYP2E1) was unchanged although total cytochrome P450 content was increased. CYP2E1 drug alcohol 10333489 Relationship between cytochrome P450 catalytic cycling and stability: fast degradation of ethanol inducible cytochrome P450 2E1 (CYP2E1) in hepatoma cells is abolished by inactivation of its electron donor NADPH cytochrome P450 reductase. CYP2E1 drug alcohol 10333489 Ethanol inducible cytochrome P450 2E1 (CYP2E1) involved in the metabolism of gluconeogenetic precursors and some cytotoxins is distinguished from other cytochrome P450 enzymes by its rapid turnover (in vivo half life of 4 7 h), with ligands to the haem iron, both substrates and inhibitors, stabilizing the protein. CYP2E1 addiction withdrawal 10333489 Fao hepatoma cells, where CYP2E1 showed a half life of 4 h upon serum withdrawal, were treated for 1 h with 0.3 microM diphenylene iodonium (DPI), a suicide inhibitor of flavoenzymes, which resulted in approximately 90% inhibition of the microsomal NADPH cytochrome P450 reductase and CYP2E1 dependent chlorzoxazone hydroxylase activities. CYP2E1 drug alcohol 9813460 Relationship between alcoholism and CYP2E1 C/D polymorphism. CYP2E1 drug alcohol 9813460 The genotypes of the CYP2E1 loci of 35 alcoholic and 130 nonalcoholic (healthy controls) Japanese were investigated to determine the relationship between CYP2E1 (C/D) polymorphism and susceptibility to alcohol dependence. CYP2E1 addiction dependence 9813460 The genotypes of the CYP2E1 loci of 35 alcoholic and 130 nonalcoholic (healthy controls) Japanese were investigated to determine the relationship between CYP2E1 (C/D) polymorphism and susceptibility to alcohol dependence. CYP2E1 drug alcohol 9813460 = 1, chi2 = 11.0, p < 0.001) difference in the CYP2E1 C gene frequency between alcohol dependents (0.41) and controls (0.28), suggesting that the C gene of CYP2E1 may be related to the risk of developing alcoholism in Japanese, whereas the frequency of the D gene was higher among controls than alcoholics. CYP2E1 drug alcohol 9731720 The RsaI polymorphism of CYP2E1 and susceptibility to alcoholic liver disease in Caucasians: effect on age of presentation and dependence on alcohol dehydrogenase genotype. CYP2E1 addiction dependence 9731720 The RsaI polymorphism of CYP2E1 and susceptibility to alcoholic liver disease in Caucasians: effect on age of presentation and dependence on alcohol dehydrogenase genotype. CYP2E1 drug alcohol 9731720 Caucasians are polymorphic at only two of these gene loci cytochrome P450 2E1 (CYP2E1) and alcohol dehydrogenase 3 (ADH3). CYP2E1 drug alcohol 9731720 We examined the frequency of the RsaI polymorphism of CYP2E1 and ADH3 genotype in 264 patients with alcoholic liver disease and 121 local control individuals. CYP2E1 drug alcohol 9731720 This study demonstrates that, although rare in Caucasians, possession of the mutant c2 allele of CYP2E1 increases the risk of alcoholic liver disease at a given level of cumulative alcohol consumption. CYP2E1 drug alcohol 9731720 This risk appears to be particularly manifest in individuals carrying the ADH3*2 allele, presumably reflecting increased metabolism of ethanol by CYP2E1. CYP2E1 drug alcohol 9695719 Inhibition of CYP2E1 by chlormethiazole as measured by chlorzoxazone pharmacokinetics in patients with alcoholism and in healthy volunteers. CYP2E1 drug alcohol 9695719 It is known that CYP2E1 is involved in the activation of many low molecular weight toxins and carcinogens and may be involved in the development of alcohol induced liver disease. CYP2E1 drug alcohol 9695719 The pharmacokinetics of a single oral dose of 250 mg chlorzoxazone, a marker of the activity of CYP2E1, were measured in five healthy drug free volunteers and in 16 patients with alcoholism receiving 1.2 gm or 2.4 gm chlormethiazole per day for 1, 2, or 3 days. CYP2E1 drug alcohol 9695719 The patients were starting an alcohol withdrawal program and were supposed to have an induced CYP2E1 activity. CYP2E1 addiction withdrawal 9695719 The patients were starting an alcohol withdrawal program and were supposed to have an induced CYP2E1 activity. CYP2E1 drug alcohol 26734919 It was also reported that polymorphism of ALDH2 and/or CYP2E1 may be associated with the susceptibility to alcohol induced liver injury. CYP2E1 drug alcohol 26734919 Concerning blood ethanol elimination kinetics, it was reported that the c2 gene of CYP2E1 and the ALDH2*1 gene may have greater effects on ethanol and acetaldehyde elimination than the other genotypes, when the blood ethanol level is below 20 m M. CYP2E1 drug alcohol 9633991 Alcohol mediated increases in acetaminophen hepatotoxicity: role of CYP2E and CYP3A. CYP2E1 drug alcohol 9633991 This commentary focuses on the roles of CYP3A and CYP2E in alcohol mediated increases in acetaminophen hepatotoxicity. CYP2E1 drug alcohol 9633991 However, CYP3A, which is also induced by alcohol, has been shown to have a greater affinity for acetaminophen than CYP2E. CYP2E1 drug alcohol 9633991 Previous experiments implicating CYP2E in alcohol mediated increases in acetaminophen hepatotoxicity have used inhibitors of this form of P450 that are now proving to be non specific. CYP2E1 drug alcohol 9633991 CYP2E may not have a major role due to the rapid loss of induced levels in the absence of continued exposure to ethanol. CYP2E1 drug alcohol 9483936 [Relationship between alcoholism and CYP2E1 genotypes]. CYP2E1 drug alcohol 9483936 The genotype of the CYP2E1 loci in 36 alcoholic and 42 non alcoholic (healthy) Japanese were investigated to examine the relationship between the polymorphisms of CYP2E1 (C/D) and the susceptibility to alcohol dependence. CYP2E1 addiction dependence 9483936 The genotype of the CYP2E1 loci in 36 alcoholic and 42 non alcoholic (healthy) Japanese were investigated to examine the relationship between the polymorphisms of CYP2E1 (C/D) and the susceptibility to alcohol dependence. CYP2E1 drug alcohol 9483936 There was a significant (df = 1, chi 2 = 4.39, p < 0.05) difference in CYP2E1 CD (heterozygote) genotype frequency between alcohol dependents (56%) and controls (33%), suggesting that the CD (heterozygote) genotype of CYP2E1 may have something to the risk of developing alcoholism in Japanese, whereas DD (homozygote) genotype was high among controls. CYP2E1 drug alcohol 9390106 Ethanol is a well known inducer of CYP2E1; whether or not it is an inducer of other cytochromes has not been investigated systematically. CYP2E1 addiction withdrawal 9249006 In the Fao hepatoma cell line, CYP2E1 was found to be fairly stable (half life of 26 h), but serum withdrawal resulted in its rapid disappearance from the microsomal fraction (half life of about 7 h) as evaluated using cycloheximide chase. CYP2E1 drug alcohol 9249006 The effect of serum withdrawal was specific for CYP2E1 since (a) no concomitant fast degradation of CYP2B1 and NADPH cytochrome P 450 reductase was observed and (b) the CYP2E1 ligands ethanol and imidazole prevented the fast degradation of the enzyme. CYP2E1 addiction withdrawal 9249006 The effect of serum withdrawal was specific for CYP2E1 since (a) no concomitant fast degradation of CYP2B1 and NADPH cytochrome P 450 reductase was observed and (b) the CYP2E1 ligands ethanol and imidazole prevented the fast degradation of the enzyme. CYP2E1 drug alcohol 9144448 CYP2E is considered the only form of cytochrome P450 responsible for ethanol mediated increases in acetaminophen hepatotoxicity. CYP2E1 drug alcohol 9144448 In rats, CYP2E has been shown to decrease to control levels after this time period of withdrawal from ethanol. CYP2E1 addiction withdrawal 9144448 In rats, CYP2E has been shown to decrease to control levels after this time period of withdrawal from ethanol. CYP2E1 drug alcohol 9144448 We have previously shown in cultured human and rat hepatocytes, and in intact rats, that ethanol induces CYP3A in addition to CYP2E. CYP2E1 drug alcohol 9144448 To determine if there might be a role for CYP3A in ethanol mediated APAP hepatotoxicity in addition to the recognized role for CYP2E, we investigated the effect of triacetyloleandomycin (TAO) on acetaminophen hepatotoxicity in ethanol pretreated rats, as well as the effect of 11 hr withdrawal from ethanol on hepatic levels of CYP3A and CYP2E. CYP2E1 addiction withdrawal 9144448 To determine if there might be a role for CYP3A in ethanol mediated APAP hepatotoxicity in addition to the recognized role for CYP2E, we investigated the effect of triacetyloleandomycin (TAO) on acetaminophen hepatotoxicity in ethanol pretreated rats, as well as the effect of 11 hr withdrawal from ethanol on hepatic levels of CYP3A and CYP2E. CYP2E1 drug alcohol 9144448 This 11 hr withdrawal from ethanol resulted in a decrease in hepatic levels of ethanol induced CYP2E; however, considerable induction was still evident.

CYP2E1 drug alcohol 8948088 We have studied the hepatic microsomal metabolism of ethanol (MEOS), CYP2E1 expression and catalytic activity, and the response to phenobarbital (PB) induction or CCl4 challenge in rats of either sex genetically selected for their preference (P) or aversion (NP) for ethanol.

CYP2E1 drug alcohol 8948088 These results indicate that, in females only, the behavioural trait of ethanol preference is apparently associated not only with higher constitutive levels of CYP2E1 and rate of microsomal metabolism of ethanol but also with altered susceptibility to PB induction. CYP2E1 drug alcohol 8812268 Metabolism of 1,2 difluoroethane by cytochrome P450 (most likely CYP2E1) is suspected because pretreatment of rats or mice with SKF 525F, disulfiram, or dimethyl sulfoxide prevented or delayed the toxicity observed in rats not pretreated.

CYP2E1 drug alcohol 7786308 Microsomes were prepared, and ethanol inducible cytochrome P4502E1 (CYP2E1) activity was measured using the enzyme markers N nitrosodimethylamine demethylase (NDMAd), p nitrophenol hydroxylase (PNPH) and aniline hydroxylase (AH). CYP2E1 addiction withdrawal 7786308 The prolonged induction of AH activity following ETOH withdrawal indicates that it is not a specific marker of CYP2E1 catalyzed reactions. CYP2E1 drug alcohol 7545990 In this study, microsomal cytochrome P 450 2E1 (CYP2E1) contents and activities were tested in liver, kidney and lung from Wistar rats after the following treatments (1) oral administration of a 10% ethanol solution for 4 weeks; (2) pair fed controls; (3) oral administration of a 5% acetone solution for 1 week; (4) inhalation of ethanol vapour for 4 weeks. CYP2E1 drug alcohol 7545990 Inhalation was clearly the most efficient way of inducing CYP2E1, probably due to the continuous and high alcohol exposure. CYP2E1 addiction intoxication 7545990 The CYP2E1 activities decreased to control values in the three tissues tested, within 24 h after cessation of intoxication. CYP2E1 drug alcohol 7625570 To evaluate cytochrome P4502E1 (CYP2E1) induction in alcoholics, the ratio of the concentrations of 6 hydroxychlorzoxazone (6 OH CHZ) and chlorzoxazone (CHZ) was measured in blood 2 hr after CHZ ingestion using a HPLC method.

EGR1 drug opioid 25290009 To better dissect the time course of opioid produced IEG induction, we used in situ hybridization to examine the expression of the IEGs c fos, zif268 and arc in the mouse forebrain at several time points after acute morphine injection. EGR1 drug cocaine 24452697 MPH + FLX, or cocaine exposure in juvenile mice increased mRNA expression of ERK2 and its downstream targets (CREB, cFos, and Zif268), and increased protein phosphorylation of ERK2 and CREB 2 months after drug exposure. EGR1 addiction relapse 24069163 After extinction training and reinstatement testing, where both cues were presented in separate sessions, rats were sacrificed and processed for cellular analysis of temporal activity by fluorescent in situ hybridization (CatFISH) for activity regulated cytoskeleton associated protein (Arc) mRNA and for radioactive in situ hybridization for Arc and zif268 mRNAs. EGR1 addiction relapse 24069163 We have shown that while rats reinstate drug seeking in response to temporally discrete presentations of distinct drug associated cues, such reinstatement is not associated with increased transcriptional activation of Arc or zif268 mRNAs, suggesting that expression of these genes may not be necessary for cue induced reinstatement of drug seeking behavior.

EGR1 drug cocaine 16672671 We examined the role of Zif268, an immediate early gene induced by drugs of abuse under the control of ERK, in behavioral responses to cocaine using knock in mutant mice in which Zif268 was replaced by LacZ. EGR1 drug cocaine 16672671 In contrast, locomotor sensitization to single or repeated cocaine injections was dramatically diminished in both heterozygous and homozygous Zif268 mutant mice.

EGR1 drug cocaine 16672671 Conditioned place preference in response to cocaine was prevented in Zif268 deficient mice. EGR1 drug cocaine 16672671 Our results provide direct genetic evidence for the requirement of Zif268 for long lasting association of environmental context with specific behavioral responses after short exposures to cocaine.

EGR1 drug cocaine 16339038 In MSK1 knock out (KO) mice CREB and H3 phosphorylation in response to cocaine (10 mg/kg) were blocked, and induction of c Fos and dynorphin was prevented, whereas the induction of Egr 1 (early growth response 1)/zif268/Krox24 was unaltered.

EGR1 drug cocaine 16157275 Here, we show that infusion of Zif268 antisense oligodeoxynucleotides into the basolateral amygdala, prior to the reactivation of a well learned memory for a conditioned stimulus (CS) cocaine association, abolishes the acquired conditioned reinforcing properties of the drug associated stimulus and thus its impact on the learning of a new cocaine seeking response.

EGR1 drug cocaine 16115217 The patterns of cocaine induced c Fos, JunB and Zif268 protein expression were investigated, using an immunohistochemical approach, within distinct nuclei of the amygdala, either in the presence or absence of a selective inhibitor of the ERK pathway, SL327. EGR1 drug cocaine 16115217 In particular, whereas c Fos and JunB expressions were augmented following chronic cocaine treatment, as compared with acute treatment, Zif268 expression was decreased by this chronic treatment. EGR1 drug cocaine 16115217 Additionally, chronic blocking of ERK activation affected cocaine induced c Fos and JunB but not Zif268 expression. EGR1 drug nicotine 15785859 We previously reported that nicotine withdrawal up regulates transcription of some immediately early genes (IEGs), c fos (Ichino et al., 1999) and egr1, nur77 (Ichino et al., 2002) in cultures of pheochromocytoma PC12 cells, which are of neuronal lineage.

EGR1 addiction intoxication 15496936 Brief social defeat stress: long lasting effects on cocaine taking during a binge and zif268 mRNA expression in the amygdala and prefrontal cortex. EGR1 drug cocaine 15496936 The objectives of the current study were to examine the enduring consequences of brief episodes of social defeat stress on cocaine bingeing (during 24 h of continuous access) and on the emergence of neural adaptations as revealed by zif268 immediate early gene expression. EGR1 drug cocaine 15496936 After 2 months, cocaine binges or zif268 mRNA gene expression were studied after confirming behavioral cross sensitization to stimulant challenge. EGR1 addiction sensitization 15496936 After 2 months, cocaine binges or zif268 mRNA gene expression were studied after confirming behavioral cross sensitization to stimulant challenge. EGR1 drug amphetamine 15496936 Persistent stress induced levels of zif268 in the central and medial amygdala were attenuated by an injection of amphetamine (1.0 mg/kg). EGR1 drug cocaine 12752796 Induction of the learning and plasticity associated gene Zif268 following exposure to a discrete cocaine associated stimulus. EGR1 drug cocaine 12752796 We investigated whether the expression of the plasticity associated gene, zif268, was associated with memories retrieved by exposure to a discrete stimulus that had been associated with cocaine, either self administered or administered noncontingently. EGR1 drug cocaine 12752796 In the absence of drug, passive presentation of a cocaine associated light stimulus induced changes in the expression of zif268 measured by in situ hybridization within a limbic cortical ventral striatal circuit that was not only regionally selective but related to whether the rats had originally received response contingent or noncontingent stimulus drug pairings. EGR1 drug cocaine 12752796 In rats that had self administered drug, the cocaine conditioned stimulus (CS) increased zif268 expression in neurons of the ventral tegmental area, nucleus accumbens core and shell, and basal nucleus of the amygdala but not hippocampus, prelimbic area of the medial prefrontal cortex or amygdala central nucleus. EGR1 drug cocaine 12752796 The same CS that had been associated with cocaine administered noncontingently additionally increased zif268 mRNA levels in area Cg1 of the anterior cingulate cortex, ventral and lateral regions of the orbitofrontal cortex and lateral nucleus of the amygdala. EGR1 drug cocaine 12752796 Zif268 induction was related to the predictive relationship between the stimulus and cocaine as no changes were seen in cocaine experienced rats that had received unpaired light and drug presentations during training. EGR1 addiction relapse 12752796 Zif268 may participate in the molecular mechanisms underlying the reconsolidation or re encoding of Pavlovian stimulus drug associations across a distributed limbic cortical ventral striatal neural network and that may contribute to the basis of the enduring drug seeking behaviour produced by environmental cues. EGR1 drug cannabinoid 12657697 In vivo THC induced the expression of immediate early genes products (c Fos protein, Zif268, and BDNF mRNAs), and this induction was prevented by an inhibitor of MEK. EGR1 drug amphetamine 12638131 Using these criteria, the mRNA for three immediate early genes (IEGs), coding for activity regulated cytoskeletal associated protein (Arc), nerve growth factor induced protein A (NGFI A; early growth response protein 1) and nerve growth factor induced protein B (NGFI B), were upregulated 1 and 3 h after amphetamine as previously described. EGR1 drug amphetamine 12112395 Similarly, in the second experiment it was found that the D1R dependent induction by AMPH of Fos, FosB, and JunB, but not NGFI A, in the NAc was enhanced in rats exposed 1 week earlier to repeated VTA AMPH. EGR1 drug cannabinoid 11388413 Effects of cannabinoids in Krox 24 targeted mice. EGR1 drug cannabinoid 11388413 Krox 24 is an immediate early gene encoding a zinc finger transcription factor implicated in several adaptive responses, and its induction by cannabinoids has been reported. EGR1 drug cannabinoid 11388413 We used mice targeted in the Krox 24 gene to specifically dissect the role of this protein in the acute and chronic central actions of cannabinoids. EGR1 drug cannabinoid 11388413 We show that Krox 24 is not involved in the acute analgesic effects of delta9 THC and in the SR precipitated delta9 THC withdrawal syndrome.

EGR1 addiction intoxication 11098116 The neuronal correlates of these behavioral and neurochemical effects of a cocaine binge were assessed using in situ hybridization histochemistry to detect changes in zif268 messenger RNA expression. EGR1 drug cocaine 11098116 The level of zif268 messenger RNA was lower upon termination of cocaine self administration than in both yoked treatment groups in the ventral tegmental area and hippocampus. EGR1 drug cocaine 11098116 In contrast, zif268 messenger RNA expression increased in the periaqueductal gray matter one day after termination of passive cocaine treatment, coincident with enhanced expression of ultrasonic vocalizations. EGR1 drug cocaine 11098116 Zif268 messenger RNA expression decreased over time in the nucleus accumbens core and infralimbic cortex, with reduced expression observed in the nucleus accumbens core, caudatoputamen, hippocampus and amygdala 14 days after termination of cocaine self administration. EGR1 drug cocaine 11098116 The results suggest that withdrawal following a cocaine self administration binge produces a long lasting reduction of constitutive zif268 messenger RNA expression in mesocorticolimbic brain regions related to the nucleus accumbens.

EGR1 drug cocaine 10986339 The suppressive effects of pentobarbital were not specific to c Fos, such that pentobarbital also suppressed expression of ITFs FosB and Egr1 in the striatum of cocaine treated rats. EGR1 drug cocaine 10971643 A low dose of cocaine, by itself essentially ineffective, produced an increase in c fos and NGFI A mRNA in the cerebral cortex in mice that had been drinking caffeine. EGR1 drug cocaine 10971643 Cocaine and caffeine also synergistically increased NGFI A expression in caudate putamen. EGR1 drug cocaine 10683479 C57BL/6J, DBA/2J, and 129/OlaHsd mice were compared as to their propensity to self administer cocaine, the ability of cocaine injection to prevent extinction of nose poking in the absence of cocaine infusion, and cocaine's effect on NGFI A and secretogranin II mRNA. EGR1 drug cocaine 10683479 A single cocaine injection (2 mg kg( )(1)) increased NGFI A mRNA and decreased secretogranin II mRNA in the caudate putamen in C57 mice.

EGR1 addiction intoxication 10683413 Differential regional zif268 messenger RNA expression in an escalating dose/binge model of amphetamine induced psychosis. EGR1 drug amphetamine 10683413 Acute amphetamine resulted in a significant elevation of zif268 messenger RNA in both the nucleus accumbens and dorsal striatum. EGR1 drug amphetamine 10683413 Agranular insular cortex and medial olfactory tubercle zif268 messenger RNA expression was also markedly increased after acute amphetamine treatment but, unlike the nucleus accumbens and dorsal striatum, this increase was not significantly attenuated by either single daily injection or multiple binge treatment. EGR1 addiction intoxication 10683413 Agranular insular cortex and medial olfactory tubercle zif268 messenger RNA expression was also markedly increased after acute amphetamine treatment but, unlike the nucleus accumbens and dorsal striatum, this increase was not significantly attenuated by either single daily injection or multiple binge treatment. EGR1 addiction intoxication 10683413 Zif268 messenger RNA expression in the lateral nucleus of the amygdala also remained elevated above baseline after binge treatment.

EGR1 drug cocaine 10564376 Intravenous cocaine self administration in mice was studied to find correlates of the acquisition of cocaine oriented operant behaviour in the expression of nerve growth factor induced clone A (NGFI A), c fos and secretogranin II mRNAs. EGR1 addiction reward 10564376 Intravenous cocaine self administration in mice was studied to find correlates of the acquisition of cocaine oriented operant behaviour in the expression of nerve growth factor induced clone A (NGFI A), c fos and secretogranin II mRNAs. EGR1 drug cocaine 10564376 Non contingent cocaine infusions increased NGFI A mRNA expression in the core of nucleus accumbens, medial caudate putamen and frontal cortex, whereas self administration eliminated these effects. EGR1 drug alcohol 10443996 In this study, immunohistochemical expression analysis of immediate early genes c fos, fosB, and zif268 was performed in brain of C57BL/6J mice after voluntary alcohol consumption. EGR1 drug alcohol 10443996 Consumption of the ethanol/sucrose solution also significantly reduced FosB expression in the basolateral amygdala and lateral hypothalamus, and Zif268 expression in the CA1 region of the hippocampus of stressed animals. EGR1 drug cocaine 9387892 Interestingly, the repression of 8G226 immediately after cocaine treatment is in direct contrast to the cocaine dependent increase in expression documented for NGFI A, another zinc finger protein which also functions as a transcriptional regulator. EGR1 addiction sensitization 9403355 During the "central sensitization" phenomenon, noxious stimuli lead to expression of IEGs (c fos, c jun, krox 24); their proteic products have been postulated to convert short term stimulations into long lasting responses in dorsal horn neurons. EGR1 drug alcohol 8749800 The present study examined fetal alcohol effects (FAE) on the induction of the immediate early genes (IEGs) c fos, jun B, c jun, and zif268 mRNAs in the prefrontal cortex, hippocampus, and other brain regions after testing in an alternation task. EGR1 drug amphetamine 7784961 This study illustrates how a 2 week, twice daily 7.5 mg/kg d amphetamine or saline regimen alters rat brain regional expression of transcription factor genes, including c fos, fos B, jun B, c jun, and zif 268, and seeks potential correlations between those changes and alterations in neurotransmitter levels and behavioral novelty responses. EGR1 drug cocaine 7854036 Previous studies have demonstrated that the IEGs NGFI A (zif268) and c fos are each rapidly induced in the caudate putamen (CP) by treatment with the indirect dopamine agonist cocaine. EGR1 drug cocaine 7854036 Previous studies have demonstrated that the IEGs NGFI A (zif268) and c fos are each rapidly induced in the caudate putamen (CP) by treatment with the indirect dopamine agonist cocaine. EGR1 drug cocaine 7854036 Levels of NGFI A and c fos were measured in the CP of rats by Northern blot analysis, which confirmed that cocaine induced increases of NGFI A and c fos mRNA lasts for several hours after drug administration. EGR1 drug cocaine 7854036 Immediately following this induction, however, there is a prolonged period during which a marked reduction in the relative amount of mRNA for both NGFI A and c fos is observed in cocaine treated animals when compared to matched, vehicle treated controls. EGR1 drug cocaine 1631058 We therefore examined changes in the mRNA levels for the IEGs c fos, c jun, fosB, junB, and zif268 in the NAc of rats treated acutely and chronically with cocaine.

CHRNA3 addiction dependence 19010884 A locus at 15q24/15q25.1, which includes the nicotinic acetylcholine receptor A subunits 3 and 5 (CHRNA3 and CHRNA5) genes, has recently been associated with lung cancer risk, self reported number of cigarettes smoked per day, and a nicotine dependence scale. CHRNA3 drug nicotine 19010884 We used urinary biomarkers to test whether two linked lung cancer risk variants in CHRNA3 (rs1051730) and CHRNA5 (rs16969968) are associated with intensity of smoking and exposure to a tobacco specific carcinogenic nitrosamine per cigarette dose. CHRNA3 drug nicotine 19010884 Thus, smokers who carry the CHRNA3 and CHRNA5 variants are expected to be at increased risk for lung cancer compared with smokers who do not carry these alleles even if they smoked the same number of cigarettes.

MTOR drug amphetamine 32120831 Lupenone Protects Neuroblastoma SH SY5y Cells Against Methamphetamine Induced Apoptotic Cell Death via PI3K/Akt/mTOR Signaling Pathway. MTOR drug nicotine 32111983 Since FGF19 could be induced by smoking or endoplasmic reticulum stress, to tackle the more malignant FGF19 overproducing LSQ, we reported for the first time that inhibiting mTOR pathway by using AZD2014 was effective and feasible. MTOR addiction sensitization 31785230 Inhibitors against PI3K, AKT and mammalian target of rapamycin (mTOR) have remarkable effects on tumor cell proliferation and radiotherapy sensitization in cell cultures and mouse models. MTOR drug opioid 31756370 Several mechanisms are involved in the tolerance to analgesic opioids, including desensitization or internalization of the opioid receptor, elevation of cAMP levels, microglial activation and neuroinflammation, elevation of spinal mTOR activity and change in the expression of some proteins involved in tolerance, such as nNOS. MTOR drug opioid 31756370 Activation of the AMPK pathway inhibits mTOR and p38 MAPK ameliorating neuroinflammation and tolerance induced by morphine. MTOR drug opioid 31747048 Moreover, morphine treatment significantly increased Beclin 1 expression and decreased the p mTOR/mTOR and SQSTM1/p62 levels, whereas knockdown of RACK1 prevented morphine induced autophagy in vitro. MTOR drug opioid 31747048 Furthermore, we found that in the mouse hippocampus, knockdown of RACK1 also markedly suppressed morphine induced autophagy (decreased LC3 II/LC3 I ratio and increased p mTOR/mTOR ratio). MTOR drug alcohol 31733664 Results also showed that alcohol use was associated with a general reduction in Akt/mTOR signaling via several phosphoproteins (IR, IRS1, IGF1R, PTEN, ERK, mTOR, p70S6K, RPS6) in multiple brain regions including hippocampus and entorhinal cortex. MTOR drug alcohol 31733664 Dysregulation of Akt/mTOR phosphoproteins suggests alcohol may target this pathway in AD progression. MTOR drug alcohol 31733185 To determine the role of adipose autophagy and mechanistic target of rapamycin (mTOR) in alcohol induced adipose and liver pathogenesis, we generated adipocyte specific Atg5 knockout (KO), adipocyte specific mTOR KO, adipocyte specific Raptor KO, and adipocyte specific tuberous sclerosis complex 1 KO mice by crossing floxed mice with Adipoq Cre.

MTOR drug alcohol 31329447 We identified significant protein expression changes in the mechanistic target of rapamycin (mTOR) canonical pathway between control and ethanol induced impulsive mice. MTOR drug alcohol 31167126 Ethanol challenge upregulated autophagy (p < 0.001), promoted AMPK phosphorylation and Sirt1 levels (p < 0.003) while suppressing mTOR phosphorylation and Skp2 levels (p < 0.02). MTOR drug alcohol 31167126 Taken together, our data revealed that CD74 ablation counteracts acute ethanol challenge induced myocardial dysfunction, inflammation and apoptosis possibly through an AMPK mTOR Skp2 mediated regulation of autophagy. MTOR drug psychedelics 31128500 Augmentation effect of ketamine by guanosine in the novelty suppressed feeding test is dependent on mTOR signaling pathway. MTOR drug psychedelics 31128500 Our results suggest that augmentation response of ketamine by guanosine in the NSF test probably involves the activation of mTOR signaling, since the treatment with rapamycin (0.2 nmol/site, i.c.v., a selective mTOR inhibitor) completely abolished this effect. MTOR addiction reward 31128500 This augmentation strategy also increased mTOR phosphorylation (Ser2448) in the hippocampus, reinforcing the role of mTOR in this augmentation response. MTOR drug psychedelics 31128500 Overall, results provide evidence that guanosine is able to augment the effect of ketamine in the NSF test via mTOR activation, a finding that might have therapeutic implications for the management of depression/anxiety.

MTOR drug amphetamine 30574066 In addition, it was found that mTOR inhibition via pharmacological intervention could trigger autophagy and promote METH and HIV Tat induced autophagy. MTOR drug opioid 30547365 Co intraperitoneal injection of rapamycin also attenuated the morphine induced increases in the levels of phosphorylated mTOR and its downstream target phosphorylated 4E BP1 in the spinal cord dorsal horn.

MTOR drug amphetamine 30261225 Collectively, our study shows that NACA protects against Meth and/or Tat induced cellular injury in vitro and in the rat striatum in vivo by attenuating oxidative stress, apoptosis and autophagy, at least in part, via modulation of mTOR signaling. MTOR drug opioid 30179451 What emerged from these studies is the discovery that certain deleterious actions mediated by the κ opioid receptors appear due to specific activation of mTOR pathways. MTOR drug opioid 30146703 Several studies have shown that mammalian target of rapamycin (mTOR) plays a crucial role in the development of opioid tolerance. MTOR drug opioid 30146703 mTOR activation suppresses opioid induced antinociception, and its activity has also been increased during opioid tolerance. MTOR drug alcohol 30130465 In large part, these alcohol induced changes are mediated by a decrease in protein synthesis that in turn is governed by impaired activity of a protein kinase, the mechanistic target of rapamycin (mTOR). MTOR drug alcohol 30130465 Herein, we summarize recent advances in understanding mTOR signal transduction, similarities and differences between the effects of alcohol on this central metabolic controller in skeletal muscle and in the heart, and the effects of acute versus chronic alcohol intake.

MTOR addiction intoxication 30114398 Binge ethanol exposure caused neurodegeneration and neuroinflammation after 5 days of exposure, and a concomitant increase of ER stress and inhibition of mTOR. MTOR drug alcohol 30114398 These results suggested that mTOR signaling is upstream of ER stress and may thereby mediate ethanol induced ER stress.

MTOR addiction aversion 30082888 The results indicate that the mTOR pathway is involved in KOR agonist induced aversion. MTOR addiction aversion 30082888 Furthermore, this is one of the first two reports that the mTOR pathway mediates aversion caused by KOR activation. MTOR addiction addiction 30061532 This review addresses the role of mTOR dependent autophagy dysfunction in a variety of neuropsychiatric disorders, to focus mainly on psychiatric syndromes including schizophrenia and drug addiction. MTOR drug amphetamine 30061532 For this reason, in the present review, a special emphasis is placed on the role of mTOR on methamphetamine induced brain alterations. MTOR addiction dependence 30044707 Instead, the 2 signals exhibited dynamic alterations in opposite directions, which could be explained by the dependence of MTORC1 (MTOR complex 1) activation on TFEB supported lysosome function and the feedback suppression of TFEB by MTORC1. MTOR addiction aversion 29930108 Thus, we discovered enrichment of the mechanistic target of rapamycin (mTOR) pathway by U 50,488H, an agonist causing aversion, which is a typical KOR mediated side effect. MTOR addiction aversion 29930108 Consequently, mTOR inhibition during KOR activation abolished aversion while preserving beneficial antinociceptive and anticonvulsant effects.

POMC drug opioid 8883945 When castrated male rats were similarly morphine pelleted and killed either on day 10 or 2 days later after pellet removal, the mean POMC mRNA level again fell from 1.83 +/ 0.21 in the controls to 1.28 +/ 0.20 pg/microgram RNA after 10 days of morphine; 2 days after pellet removal levels remained suppressed at 0.80 +/ 0.08 pg/microgram RNA (P < 0.01). POMC drug opioid 8883945 We conclude that morphine suppresses POMC gene expression in the hypothalamus of chronically treated male and female rats.

GFAP drug opioid 8228992 No alterations in GFAP levels were observed in response to chronic morphine in several other regions of the CNS studied, including the substantia nigra, locus coeruleus, cerebral cortex, and spinal cord. GFAP drug opioid 8228992 There were also inherent differences in levels of GFAP immunoreactivity in the VTA of drug naive Fischer 344 and Lewis rats, two inbred rat strains that differ in their relative preference for morphine and other drugs of abuse. GFAP addiction addiction 8228992 Because the mesolimbic dopamine system is thought to play a critical role in mediating the reinforcing properties of opiates and other drugs of abuse, it is possible that the opiate induction of GFAP and inherent Lewis versus Fischer strain differences in GFAP levels in the VTA may be related to the reinforcing and/or addictive properties of opiates mediated by this brain region, as well as to genetic differences in drug preference.

CYP2D6 drug psychedelics 27400739 The major CYP enzymes involved in the metabolism of 25I NBOMe and 25INBOH were identified as CYP3A4 and CYP2D6, respectively. CYP2D6 drug alcohol 27376791 Although several environmental and socio demographic/diagnostic variables such as alcohol/drug abuse, and medication non compliance accounted for a significant proportion of the ability to predict RD prevalence and frequency, the pharmacogenetics of CYP, particularly CYP2D6, may help to identify BD patients at risk for ADRs and TFs. CYP2D6 drug opioid 27061230 To examine whether certain genotypes were associated with this, we examined the frequencies of 29 SNPs located in candidate genes related to opioid pharmacology: ABCB1, OPRM1, UGT2B7, CYP3A5, CYP2B6, CYP2C19, CYP2D6, COMT, KCNJ6 and SCN9A in 274 deceased patients with OA (DOA), 309 living patients with OA (LOA) and in 394 healthy volunteers (HV). CYP2D6 drug opioid 27042732 The potency of codeine and tramadol is strongly influenced by the cytochrome P450 isoenzyme CYP2D6 genotype, which varies widely from one person to another. CYP2D6 drug opioid 27042732 The potency of morphine and that of buprenorphine, an opioid receptor agonist antagonist, appears to be independent of CYP2D6 activity. CYP2D6 drug opioid 26986973 There was also a large variability in calculated ratios of morphine to codeine, C6G to codeine and norcodeine to codeine in all matrices, and CYP2D6 genotype was not a reliable predictor of these ratios. CYP2D6 drug psychedelics 26807959 PHARMACOKINETICS AND PHARMACODYNAMICS: Ibogaine is metabolized mainly by CYP2D6 to the primary metabolite noribogaine (10 hydroxyibogamine). CYP2D6 drug psychedelics 26807959 TOXICITY FROM DRUG DRUG INTERACTION: Polymorphism in the CYP2D6 enzyme can influence blood concentrations of both ibogaine and its primary metabolite, which may have implications when a patient is taking other medication that is subject to significant CYP2D6 metabolism.

CYP2D6 drug psychedelics 16714321 The aim of this study was to model the in vivo kinetic consequences of mechanism based inhibition (MBI) of CYP2D6 by 3,4 methylenedioxymethamphetamine (MDMA, ecstasy). CYP2D6 drug psychedelics 16714321 A model with physiologically based components of drug metabolism was developed, taking account of change in the hepatic content of active CYP2D6 due to MBI by MDMA. CYP2D6 drug psychedelics 16714321 The analysis suggested that a typical recreational MDMA dose could inactivate most hepatic CYP2D6 within an hour, and the return to a basal level of CYP2D6 could take at least 10 days.

CYP2D6 drug psychedelics 11505218 It was apparent that (+) and ( ) MAMP NDM and MDMA demethylenation were most significantly different in CYP2D6.10. CYP2D6 drug psychedelics 11505218 Using DEX as the substrate, the ratios of Ki(*10)/Ki(*1) for inhibitors were: budipine (1.3), sparteine (1.6), debrisoquine (8.1), fluoxetine (16), norfluoxetine (30), paroxetine (14), MDMA (21) and MMDA 2 (7.1), indicating that CYP2D6.10 shows drug specific altered susceptibility to inhibition.

CYP2D6 drug psychedelics 9698290 In this report, evidence is presented that the O demethylation of ibogaine observed in human hepatic microsomes is catalyzed primarily by the polymorphically expressed cytochrome P 4502D6 (CYP2D6). CYP2D6 drug psychedelics 9698290 In hepatic microsomes from a panel of human donors, the low KMapp ibogaine O demethylase activity correlated with CYP2D6 catalyzed bufuralol 1' hydroxylase activity but not with other P450 isoform specific activities. CYP2D6 drug psychedelics 9698290 Quinidine, a CYP2D6 specific inhibitor, inhibited ibogaine O demethylase (IC50 = 0.2 microM), whereas other P450 isoform specific inhibitors did not inhibit this activity.

CYP2D6 addiction dependence 9352573 This under representation of poor metabolizers (Fisher's exact test, p < or = 0.05) in people dependent on oral opiates suggests that the CYP2D6 defective genotype is a pharmacogenetic protection factor for oral opiate dependence (estimated odds ratio > 7).

CYP2D6 drug psychedelics 9311621 The results of studies with human liver microsomes including those from a genetically poor metabolizer with respect to CYP2D6, showing correlation between MeAmp and metoprolol hydroxylation and MDMA demethylenation, were consistent with a major involvement of CYP2D6 in the aromatic 4 hydroxylation of MeAmp. CYP2D6 drug psychedelics 9311621 In contrast to MeAmp, MDMA was not N demethylated by CYP2D6. CYP2D6 addiction addiction 9311621 Since CYP2D6 participates in the major steps of MeAmp metabolism, pharmacokinetic interactions are likely with other drug substrates proposed for the treatment of MeAmp addiction.

CYP2D6 addiction dependence 9067326 Humans that lack cytochrome P450 2D6 (CYP2D6) activity may have an altered risk of drug dependence or abuse because this enzyme is important in the metabolism of some drugs of abuse, including hydrocodone. CYP2D6 drug opioid 9067326 In rats, hydrocodone conversion to hydromorphone is catalyzed by CYP2D1, the rat homolog of the human CYP2D6. CYP2D6 drug opioid 9067326 Because inhibition of CYP2D1 in this rat strain is proposed to be a useful animal counterpart for studying the impact of CYP2D6 polymorphism in humans, these data suggest that differences in CYP2D6 phenotype will have limited influence on the drug response to hydrocodone after nonoral administration. CYP2D6 drug opioid 9190321 The rate of production of this M1 derivative (O demethyl tramadol), is influenced by a polymorphic isoenzyme of the debrisoquine type, cytochrome P450 2D6 (CYP2D6).

CYP2D6 drug opioid 8845855 Lack of influence of codeine on experimental pain in PM as well as in EM treated with the CYP2D6 blocker quinidine, who are both practically unable to convert codeine to morphine, has supported an old hypothesis that codeine acts through metabolically formed morphine. CYP2D6 drug opioid 8845855 Such a local morphine formation from codeine, which supposedly is also catalysed by CYP2D6, could explain why the hypoalgesic effect of codeine stems from morphine despite relatively low plasma levels of morphine after standard hypoalgesic doses of codeine. CYP2D6 drug opioid 8845855 Dependence of codeine hypoalgesia on morphine formation via CYP2D6 makes this effect liable to interaction with drugs that are inhibitors of CYP2D6.

NEUROTENSIN drug alcohol 31744862 Here we show that ablation of a population of neurotensin expressing neurons in the central amygdala decreases intake of and preference for ethanol in non dependent animals, whereas the projection of these neurons to the parabrachial nucleus promotes consumption of ethanol as well as other palatable fluids.

NEUROTENSIN drug cocaine 16574078 This study was aimed at determining whether repeated activation of neurotensin receptors sensitizes to cocaine induced locomotor activity and whether this effect can be prevented by blockade of N methyl d aspartate receptors. NEUROTENSIN addiction reward 16574078 Independent groups of male rats were injected on four occasions, every other day (training phase), with vehicle or one of two doses (4 and 8 mg/kg) of the NMDA antagonist CPP [(+/ ) 3 (2 carboxypiperazine 4 yl) propanephosphonic)] followed by an intracerebroventricular injection of 18 nmol/10 microl of d Tyr[(11)]neurotensin, or its vehicle. NEUROTENSIN addiction reward 16574078 Results show that during the training phase d Tyr[(11)]neurotensin produced an initial suppression of all locomotor responses followed by an augmentation of ambulatory and non ambulatory activity compared to controls, effects that were only slightly altered by CPP.

CYP3A4 drug opioid 19133059 Between 61 and 68% of the overall variation in total plasma trough concentrations of (RS) , (R) and (S) methadone was explained by methadone dose, duration of addiction before starting MMT, CYP3A activity and illicit morphine use. CYP3A4 addiction addiction 19133059 Between 61 and 68% of the overall variation in total plasma trough concentrations of (RS) , (R) and (S) methadone was explained by methadone dose, duration of addiction before starting MMT, CYP3A activity and illicit morphine use. CYP3A4 drug opioid 19133059 CYP3A activity explained 22, 16, 15 and 23% of the variation in unbound (R) , unbound (S) , total (RS) and total (S) methadone clearances, respectively. CYP3A4 drug opioid 19133059 CYP3A activity has a modest influence on methadone disposition. CYP3A4 drug opioid 17480178 Recent studies suggest that QT prolongation with methadone is context dependent: occurrence is more frequent with high doses of methadone, concomitant administration of CYP3A4 inhibitors, hypokalemia, hepatic failure, administration of other QT prolonging drugs and pre existing heart disease. CYP3A4 drug alcohol 17392391 Role of CYP3A and CYP2E1 in alcohol mediated increases in acetaminophen hepatotoxicity: comparison of wild type and Cyp2e1( / ) mice. CYP3A4 drug alcohol 17392391 At the time of APAP administration, which followed an 11 h withdrawal from the alcohols, alcohol induced levels of CYP3A were sustained in both mouse lines, whereas CYP2E1 was decreased to constitutive levels in wild type mice. CYP3A4 addiction withdrawal 17392391 At the time of APAP administration, which followed an 11 h withdrawal from the alcohols, alcohol induced levels of CYP3A were sustained in both mouse lines, whereas CYP2E1 was decreased to constitutive levels in wild type mice. CYP3A4 drug alcohol 17392391 In conclusion, these findings suggest that both CYP3A and CYP2E1 contribute to APAP hepatotoxicity in alcohol treated mice. CYP3A4 addiction dependence 17284003 Cytochrome P450 3A4 (CYP3A4) is a key enzyme responsible for the metabolism of 50% of all orally administered drugs which exhibit an intriguing kinetic behavior typified by a sigmoidal dependence of the reaction velocity on the substrate concentration. CYP3A4 drug benzodiazepine 17284003 Diazepam is such a drug that undergoes metabolism by CYP3A4 with sigmoidal dependence. CYP3A4 addiction dependence 17284003 Diazepam is such a drug that undergoes metabolism by CYP3A4 with sigmoidal dependence. CYP3A4 drug opioid 17084876 Thus, our aim was to study the consequences of CYP3A induction on buprenorphine associated effects on resting ventilation in rats. CYP3A4 drug opioid 17084876 In dexamethasone pretreated rats, there was no significant alteration in the respiratory parameters, despite CYP3A induction and significant increase of the ratio of plasma norbuprenorphine to buprenorphine concentrations. CYP3A4 drug opioid 17084876 Our results suggest a limited role of drug mediated CYP3A induction in the occurrence of buprenorphine attributed respiratory depression in addicts. CYP3A4 drug opioid 16634729 Possible causes, such as the inhibition of CYP3A4 induced by cyclosporine causing elevations of serum fentanyl, are discussed. CYP3A4 drug opioid 16507617 QT interval increases were observed with buprenorphine/naloxone in combination with either delavirdine or ritonavir, which inhibit CYP3A4. CYP3A4 drug amphetamine 16250257 It is metabolized in the organism with a reaction that is catalyzed by cytochrome P450, mainly by the CYP2D and CYP3A subfamily, 4 hydroxyamphetamine and amphetamine being dominant metabolites. CYP3A4 drug opioid 16184033 To determine if atazanavir, a once daily protease inhibitor and moderate inhibitor of P450 CYP3A4, exhibited pharmacokinetic interactions with (R) methadone. CYP3A4 drug alcohol 16126318 Ethanol has been reported to be either an inducer or an inhibitor of CYP3A expression. CYP3A4 drug opioid 15966752 Buprenorphine dosage does not need to be significantly adjusted in patients with renal impairment; however, since CYP3A activity may be decreased in patients with severe chronic liver disease, it is possible that the metabolism of buprenorphine will be altered in these patients. CYP3A4 drug opioid 15966752 Although there is limited evidence in the literature to date, drugs that are known to inhibit or induce CYP3A4 have the potential to diminish or enhance buprenorphine N dealkylation. CYP3A4 drug opioid 15509185 The O demethylation of tramadol to M1, the main analgesic effective metabolite, is catalysed by cytochrome P450 (CYP) 2D6, whereas N demethylation to M2 is catalysed by CYP2B6 and CYP3A4. CYP3A4 drug opioid 15501692 Methadone is mostly metabolised in the liver; the main step consists in the N demethylation by CYP3A4 to EDDP (2 ethylidene 1,5 dimethyl 3,3 diphenylpyrrolidine), an inactive metabolite. CYP3A4 drug opioid 15501692 The activity of CYP3A4 varies considerably among individuals, and such variability is the responsible for the large differences in methadone bioavailability. CYP3A4 drug opioid 15501692 In particular, antiretrovirals, which are CYP3A4 inducers, can decrease the levels of methadone, so causing withdrawal symptoms. CYP3A4 addiction withdrawal 15501692 In particular, antiretrovirals, which are CYP3A4 inducers, can decrease the levels of methadone, so causing withdrawal symptoms. CYP3A4 drug opioid 15501692 Buprenorphine, too, is metabolised by CYP3A4, and may undergo the same interactions as methadone. CYP3A4 drug opioid 15371986 However, the role of CYP3A4 in human methadone disposition in vivo is unclear. CYP3A4 drug opioid 15371986 This investigation tested the hypothesis that CYP3A induction (or inhibition) would increase (or decrease) methadone metabolism and clearance in humans. CYP3A4 drug benzodiazepine 15371986 They received intravenous (IV) midazolam (to assess CYP3A4 activity) and then simultaneous oral deuterium labeled and IV unlabeled methadone after pretreatment with rifampin (INN, rifampicin) (hepatic/intestinal CYP3A induction), troleandomycin (hepatic/intestinal CYP3A inhibition), grapefruit juice (selective intestinal CYP3A inhibition), or nothing.

CYP3A4 drug opioid 15371986 There was no correlation between methadone clearance and hepatic CYP3A4 activity. CYP3A4 drug opioid 15371986 In vitro experiments showed a predominant role for both CYP3A4 and CYP2B6 in liver microsomal methadone N demethylation. CYP3A4 drug opioid 15371986 Intestinal and hepatic CYP3A activity only slightly affects human methadone N demethylation but has no significant effect on methadone concentrations, clearance, or clinical effects. CYP3A4 drug opioid 15371986 Interindividual variability and drug interactions affecting intestinal transporter and hepatic CYP3A and CYP2B6 activity may alter methadone disposition. CYP3A4 drug nicotine 15364541 Nicotine, the psychoactive and addictive chemical in cigarettes, and a known inducer of brain CYP2B6, was an efficacious activator of PXR and inducer of CYP3A4 transcription. CYP3A4 addiction addiction 15364541 Nicotine, the psychoactive and addictive chemical in cigarettes, and a known inducer of brain CYP2B6, was an efficacious activator of PXR and inducer of CYP3A4 transcription. CYP3A4 drug benzodiazepine 14586385 We analyzed whether CYP3A4 messenger ribonucleic acid (mRNA) concentrations in leukocytes reflect CYP3A activity in the liver measured by alprazolam as an in vivo probe drug. CYP3A4 drug benzodiazepine 14586385 We analyzed whether CYP3A4 messenger ribonucleic acid (mRNA) concentrations in leukocytes reflect CYP3A activity in the liver measured by alprazolam as an in vivo probe drug. CYP3A4 drug benzodiazepine 14586385 However, mRNA concentrations before and during rifampin induction were largely overlapping, and there was a poor correlation between mRNA concentrations and alprazolam 10 hour trough concentrations reflecting CYP3A4 activity (r = 0.4, P <.001). CYP3A4 drug benzodiazepine 12751920 While triazolam and midazolam are biotransformed almost entirely via CYP3A4, the newer hypnosedatives are biotransformed by several CYP isozymes in addition to CYP3A4, resulting in CYP3A4 inhibitors and inducers having a lesser effect on their biotransformation. CYP3A4 drug opioid 12621385 Systemic clearance of the opioid alfentanil after intravenous administration is an excellent in vivo probe for hepatic cytochrome P4503A (CYP3A) activity and drug interactions. CYP3A4 drug opioid 12405865 Rifampicin (rifampin), phenobarbital, phenytoin, carbamazepine, nevirapine, and efavirenz decrease methadone blood concentrations, probably by induction of CYP3A4 activity, which can result in severe withdrawal symptoms. CYP3A4 addiction withdrawal 12405865 Rifampicin (rifampin), phenobarbital, phenytoin, carbamazepine, nevirapine, and efavirenz decrease methadone blood concentrations, probably by induction of CYP3A4 activity, which can result in severe withdrawal symptoms. CYP3A4 drug opioid 12405865 Inhibitors of CYP3A4, such as fluconazole, and of CYP2D6, such as paroxetine, increase methadone blood concentrations. CYP3A4 drug opioid 11504799 Metabolism of methadone and levo alpha acetylmethadol (LAAM) by human intestinal cytochrome P450 3A4 (CYP3A4): potential contribution of intestinal metabolism to presystemic clearance and bioactivation. CYP3A4 drug opioid 11504799 Methadone and LAAM are metabolized by CYP3A4 in human liver. CYP3A4 drug opioid 11504799 Since they are administered orally, and CYP3A4 is expressed in human intestine, we tested the hypotheses that human intestine can metabolize methadone and LAAM, and evaluated the participation of CYP3A4. CYP3A4 drug opioid 11504799 Methadone N demethylation by CYP3A4 showed biphasic Eadie Hofstee plots without evidence of positive cooperativity; K(m) values were 10 and 1100 microM for EDDP and 20 and 1000 microM for EMDP formation. CYP3A4 drug opioid 11504799 We conclude that methadone, LAAM, and nor LAAM are metabolized by human intestinal microsomes; CYP3A4 is the predominant cytochrome P450 isoform; CYP3A4 catalyzed methadone, LAAM, and nor LAAM metabolism is characterized by noncooperative, multisite kinetics; and intestinal metabolism may contribute to presystemic methadone inactivation and LAAM bioactivation. CYP3A4 drug benzodiazepine 11259570 LAAM and nor LAAM metabolism was inhibited by the CYP3A4 selective inhibitors troleandomycin, erythromycin, ketoconazole, and midazolam. CYP3A4 drug opioid 11069437 Steady state pharmacokinetics of unbound methadone are stereoselective, and there is large interindividual variability consistent with CYP3A4 mediated metabolism to the major metabolite EDDP; the variability did not obscure a significant dose plasma concentration relationship. CYP3A4 drug benzodiazepine 10935688 The findings are consistent with the complete dependence of triazolam clearance on CYP3A activity, compared with the partial dependence of zolpidem clearance on CYP3A. CYP3A4 addiction dependence 10935688 The findings are consistent with the complete dependence of triazolam clearance on CYP3A activity, compared with the partial dependence of zolpidem clearance on CYP3A. CYP3A4 drug benzodiazepine 10773013 The complete dependence of triazolam clearance on CYP3A activity, as opposed to the mixed CYP participation in zolpidem clearance, may explain the differing sex effects on clearance of the two compounds. CYP3A4 addiction dependence 10773013 The complete dependence of triazolam clearance on CYP3A activity, as opposed to the mixed CYP participation in zolpidem clearance, may explain the differing sex effects on clearance of the two compounds. CYP3A4 drug benzodiazepine 10770452 In vitro data show the inhibition of alprazolam metabolism by sertraline via CYP3A4; therefore, using a randomized, double blind, placebo controlled design, the authors conducted this study to assess the potential for similar in vivo inhibition in humans. CYP3A4 drug opioid 10641980 Because ritonavir can induce CYP3A, it can decrease methadone plasma levels. CYP3A4 drug opioid 10383559 A time dependent increase in the clearance of methadone is consistent with auto induction of CYP3A4, the enzyme responsible for much of the metabolism of the drug. CYP3A4 drug alcohol 9633991 Alcohol mediated increases in acetaminophen hepatotoxicity: role of CYP2E and CYP3A. CYP3A4 drug alcohol 9633991 This commentary focuses on the roles of CYP3A and CYP2E in alcohol mediated increases in acetaminophen hepatotoxicity. CYP3A4 drug alcohol 9633991 However, CYP3A, which is also induced by alcohol, has been shown to have a greater affinity for acetaminophen than CYP2E. CYP3A4 drug alcohol 9633991 In rats treated with ethanol or the combination of ethanol and isopentanol, the major higher chain alcohol in alcoholic beverages, TAO protects animals from increases in acetaminophen hepatotoxicity, suggesting a major role of CYP3A. CYP3A4 drug alcohol 9144448 Role of CYP3A in ethanol mediated increases in acetaminophen hepatotoxicity. CYP3A4 drug alcohol 9144448 We have previously shown in cultured human and rat hepatocytes, and in intact rats, that ethanol induces CYP3A in addition to CYP2E. CYP3A4 drug alcohol 9144448 To determine if there might be a role for CYP3A in ethanol mediated APAP hepatotoxicity in addition to the recognized role for CYP2E, we investigated the effect of triacetyloleandomycin (TAO) on acetaminophen hepatotoxicity in ethanol pretreated rats, as well as the effect of 11 hr withdrawal from ethanol on hepatic levels of CYP3A and CYP2E. CYP3A4 addiction withdrawal 9144448 To determine if there might be a role for CYP3A in ethanol mediated APAP hepatotoxicity in addition to the recognized role for CYP2E, we investigated the effect of triacetyloleandomycin (TAO) on acetaminophen hepatotoxicity in ethanol pretreated rats, as well as the effect of 11 hr withdrawal from ethanol on hepatic levels of CYP3A and CYP2E. CYP3A4 drug alcohol 9144448 In ethanol pretreated rats, exposure to APAP in the absence of TAO was associated with a 75% decrease in CYP3A, compared to animals exposed to APAP in the presence of TAO. CYP3A4 drug alcohol 9144448 Our findings suggest that CYP3A has a major role in ethanol mediated increases in acetaminophen hepatotoxicity.

CORT addiction sensitization 31506004 CB1 receptor antagonism disrupted the expression of CORT response habituation and some of the c fos mRNA reduction associated with it and facilitated novel stressor sensitization in doses that did not potentiate acute responses to these stressors. CORT drug cocaine 31103524 This study measured differences in cognitive behavior performance on the object recognition test (ORT) and social recognition test (SRT) and serum levels of corticosterone (CORT) between C57BL/6J and BALB/cJ mice after 14 day chronic exposure to either cocaine (5 mg/kg) or morphine (3 mg/kg) at a dosage of 10 ml/kg/day. CORT drug opioid 31103524 This study measured differences in cognitive behavior performance on the object recognition test (ORT) and social recognition test (SRT) and serum levels of corticosterone (CORT) between C57BL/6J and BALB/cJ mice after 14 day chronic exposure to either cocaine (5 mg/kg) or morphine (3 mg/kg) at a dosage of 10 ml/kg/day. CORT drug cocaine 31103524 In conclusion, changes in object and social learning recognition indicate that C57BL/6J mice are more sensitive than BALB/cJ mice to chronic drug exposure, especially to cocaine; concomitant changes in serum CORT may mediate these effects. CORT drug nicotine 31099135 Stress and nicotine during adolescence resulted in higher expression of hippocampal glucocorticoid receptors and corticotropin releasing factor receptors and blunted restraint induced CORT release in adulthood. CORT drug alcohol 30946835 After the housing/running procedure, we tested anxiety like behavior using the elevated plus maze and stress responsivity by measuring corticosterone (CORT) levels before and after a swim stressor; then, rats were allowed intermittent access to ethanol in two bottle choice design for four weeks. CORT drug opioid 30898663 WBDs increased glucocorticoid receptor immunoreactivity in the pre frontal cortex, increasing corticosterone (CORT) and adrenocorticotrophic hormone (ACTH) per se and after morphine reinstatement. CORT addiction relapse 30898663 WBDs increased glucocorticoid receptor immunoreactivity in the pre frontal cortex, increasing corticosterone (CORT) and adrenocorticotrophic hormone (ACTH) per se and after morphine reinstatement. CORT addiction addiction 30450375 Experiment 1 examined adaptation in the corticosterone (CORT) response at key points in the 11 day procedure, and found that the escalation in stressors disrupted habituation to restraint, whereas the CORT response to daily forced swim exposure increased across days. CORT addiction addiction 30326391 Delays in pubertal timing and decreases in CORT levels were correlated, however, with increased novelty seeking in adult males a phenotype associated with increased addiction vulnerability. CORT addiction relapse 30326391 Delays in pubertal timing and decreases in CORT levels were correlated, however, with increased novelty seeking in adult males a phenotype associated with increased addiction vulnerability.

CORT addiction relapse 30322021 Adolescent corticosterone (CORT) exposure increased alcohol, but not sucrose, self administration, and enhanced stress induced reinstatement with yohimbine in adulthood. CORT drug alcohol 30322021 Phosphoproteomic analysis indicated that the amygdala phosphoproteome was significantly altered by adolescent CORT exposure, generating a list of potential novel mechanisms involved in the risk of alcohol drinking. CORT addiction intoxication 29966824 Plasma CORT levels were increased significantly in both binge and control animals after PS. CORT addiction intoxication 29966824 CORT levels at 24 h withdrawal from daily 10E intake were highest in the groups with elevated 10E licks (i.e., binge males and control females). CORT addiction withdrawal 29966824 CORT levels at 24 h withdrawal from daily 10E intake were highest in the groups with elevated 10E licks (i.e., binge males and control females). CORT drug alcohol 29572015 Differences in alcohol intake, blood alcohol level, and plasma CORT levels did not explain results. CORT drug opioid 29486222 Because the opioid system and HPA axis are sexually dimorphic, we examined NTX's effect on adrenocorticotropic hormone (ACTH) and corticosterone (CORT) levels. CORT drug alcohol 29486222 However, NTX increased CORT levels for longer durations in alcohol drinking males relative to alcohol drinking females in diestrus. CORT drug cannabinoid 29413435 Cannabis smokers reporting at least one trauma exposure had higher CORT and anxiety overall compared to those reporting no trauma. CORT drug nicotine 29413435 Cannabis smokers reporting at least one trauma exposure had higher CORT and anxiety overall compared to those reporting no trauma. CORT drug alcohol 29115641 Positive correlations between alcohol preference and ACTH and CORT levels were also observed. CORT drug cocaine 29061385 Regardless of rearing condition, rats exposed to modSPS had greater corticosterone (CORT) release and reduced cocaine self administration during initial acquisition compared to non stressed controls.

CORT drug alcohol 28647675 Further, voluntary ethanol drinking in CIE (CIE ED) and CIE naïve (ED) rats, and effects of CIE ED and ED on peak CORT levels and mPFC GR were investigated during acute withdrawal (8h) and protracted abstinence (28d). CORT addiction withdrawal 28647675 Further, voluntary ethanol drinking in CIE (CIE ED) and CIE naïve (ED) rats, and effects of CIE ED and ED on peak CORT levels and mPFC GR were investigated during acute withdrawal (8h) and protracted abstinence (28d). CORT addiction withdrawal 28647675 Collectively, the data demonstrate that acute withdrawal from CIE produces robust alterations in GR signaling, CORT and negative affect symptoms which could facilitate excessive drinking. CORT drug cocaine 28550455 Then, we tested acute systemic LY2444296 in reducing anxiety and depression like behaviors, as well as releasing the stress hormone corticosterone (CORT), observed after chronic extended access (18 h/day for 14 days) cocaine self administration. CORT addiction aversion 28550455 LY2444296 blocked U69,593 induced place aversion and reduced motor activity as well as U69,593 induced release of serum CORT, confirming its major site of action, without exerting an effect per se. CORT drug cocaine 28550455 Acute systemic administration of LY2444296 reduced anxiety like and depressive like behaviors, as well as CORT release, in rats tested after chronic extended access cocaine self administration, but not in cocaine naïve rats. CORT drug alcohol 28522965 In all experiments, blood samples were collected for later assessment of corticosterone (CORT), blood ethanol concentrations (BECs), and the cellular fraction of blood was analyzed for cytokine gene expression. CORT drug alcohol 27527158 (1) Fkbp5 KO and wild type (WT) EtOH consumption was tested using a two bottle choice paradigm; (2) The EtOH elimination rate was measured after intraperitoneal (IP) injection of 2.0 g/kg EtOH; (3) Blood alcohol concentration (BAC) was measured after 3 h limited access of alcohol; (4) Brain region expression of Fkbp5 was identified using LacZ staining; (5) Baseline corticosterone (CORT) was assessed. CORT addiction relapse 27316790 Antalarmin, a selective CRF1 receptor antagonist, Metyrapone, a corticosterone (CORT) synthesis inhibitor and CORT were evaluated for their effects on the reinstatement test in a cue induced relapse model. CORT drug cocaine 27001454 Finally, the presence of companions decreased the magnitude of the CPP could not seem to be accounted for by cocaine stimulated corticosterone (CORT) release. CORT addiction reward 27001454 Finally, the presence of companions decreased the magnitude of the CPP could not seem to be accounted for by cocaine stimulated corticosterone (CORT) release. CORT drug alcohol 26537217 Previous research has shown that hyperactivation in ventral medial prefrontal cortex (VmPFC) and rostral anterior cingulate cortex (rACC) and high cortisol to corticotrophin ratio (cort:ACTH ratio) during neutral relaxed states predict relapse in alcohol dependent (AD) patients. CORT addiction relapse 26537217 Previous research has shown that hyperactivation in ventral medial prefrontal cortex (VmPFC) and rostral anterior cingulate cortex (rACC) and high cortisol to corticotrophin ratio (cort:ACTH ratio) during neutral relaxed states predict relapse in alcohol dependent (AD) patients. CORT drug alcohol 26537217 Neutral relaxed state cort:ACTH ratio was significantly associated with VmPFC hyperreactivity to neutral relaxing cues, and also with hypoactivation in response to alcohol and stress cues in AD patients. CORT addiction relapse 26537217 Basal heart rate, neutral cort:ACTH ratio and neutral VmPFC hyperreactivty were each associated with risk of relapse. CORT addiction relapse 26537217 However, abnormal VmPFC activation and elevated cort:ACTH ratio overlap in predicting risk for relapse, and dysfunctional VmPFC response was the sole significant predictor of odds of relapse in a joint model of relapse risk. CORT drug alcohol 26537217 These findings suggest that the cort:ACTH ratio may serve as a peripheral marker of VmPFC brain dysfunction, while aberrant VmPFC responses need further evaluation as a potential biomarker of alcohol relapse risk in clinical outcome studies.

CORT drug alcohol 25709101 Males also showed elevated CORT levels following an acute alcohol injection of 2.0 g/kg, while females displayed blunted ACTH levels. CORT drug cocaine 25655510 Rats raised in these housing conditions were tested for their cocaine responding after pretreatment with the GR antagonist, RU486, or the GR agonist, corticosterone (CORT). CORT drug cocaine 25655510 IC rats were unaffected by RU486 pretreatment, but earned significantly more cocaine than EC rats after pretreatment with CORT (10mg/kg). CORT drug cocaine 25613133 Didehydro cortistatin A inhibits HIV 1 Tat mediated neuroinflammation and prevents potentiation of cocaine reward in Tat transgenic mice. CORT addiction reward 25613133 Didehydro cortistatin A inhibits HIV 1 Tat mediated neuroinflammation and prevents potentiation of cocaine reward in Tat transgenic mice. CORT addiction intoxication 25601008 Given that glucocorticoids can function as anti inflammatories, are known to increase with EtOH exposure, and influence neurotoxicity, we hypothesized that males and females may exhibit an altered corticosterone (CORT) response following chronic intoxication. CORT addiction withdrawal 25601008 Analysis of serum CORT levels revealed the expected increase during withdrawal with no difference between males and females, while control males but not females exhibited higher CORT concentrations than naive animals. CORT drug alcohol 25441946 RIA showed significantly increased plasma levels of CORT and ACTH in the ethanol withdrawn rats compared with the saline treated rats, which were inhibited significantly by the acupuncture at the acupoint ST36 but not at the non acupoint. CORT addiction reward 25086310 In addition, we examined for comparison another reinforcing substance, sucrose, and also took measurements of stress related behaviors and circulating corticosterone (CORT) and triglycerides (TG), to determine if they contribute to these substances' behavioral and physiological effects. CORT drug alcohol 25086310 Adult Sprague Dawley rats were gavaged three times daily over 5 days with 3.5 mL of water, Intralipid (20% v/v), ethanol (12% v/v), nicotine (0.01% w/v) or sucrose (22% w/v) (approximately 7 kcal/dose), and tail vein blood was collected for measurements of circulating CORT and TG. CORT drug nicotine 25086310 Adult Sprague Dawley rats were gavaged three times daily over 5 days with 3.5 mL of water, Intralipid (20% v/v), ethanol (12% v/v), nicotine (0.01% w/v) or sucrose (22% w/v) (approximately 7 kcal/dose), and tail vein blood was collected for measurements of circulating CORT and TG. CORT drug alcohol 25086310 While having little effect on stress related behaviors or CORT levels, fat, ethanol, and nicotine all increased circulating levels of TG. CORT drug nicotine 25086310 While having little effect on stress related behaviors or CORT levels, fat, ethanol, and nicotine all increased circulating levels of TG. CORT addiction relapse 24874934 Behaviour in unknown environment was examined in open field test (Laboras), active drug seeking behaviour in conditioned place preference test (CPP), spatial memory in the Morris water maze (MWM), and levels of corticosterone (CORT) were analyzed by enzyme immunoassay (EIA). CORT addiction reward 24874934 Behaviour in unknown environment was examined in open field test (Laboras), active drug seeking behaviour in conditioned place preference test (CPP), spatial memory in the Morris water maze (MWM), and levels of corticosterone (CORT) were analyzed by enzyme immunoassay (EIA). CORT drug alcohol 23994181 LMS increases ethanol induced locomotor response and self administration, possibly due to changes in CORT release and/or monoamine concentrations. CORT drug alcohol 23994181 This study examined the effects of LMS in association with chronic ethanol treatment on plasma CORT and brain monoamine concentrations in male and female Swiss mice, which were kept undisturbed (animal facility rearing AFR) or separated from their mothers for 3h/day, from 2 to 14 days of age (LMS). CORT drug alcohol 23994181 Locomotor activity, plasma CORT levels and monoamines in the frontal cortex, striatum and hippocampus of AFR and LMS mice were evaluated in non treated, acute and chronic ethanol treated animals. CORT drug alcohol 23994181 Moreover, chronic ethanol treatment resulted in higher CORT concentrations in LMS than in AFR males. CORT drug alcohol 23994181 Overall, these results indicate that LMS mice were more susceptible to the effects of chronic ethanol administration on CORT and brain monoamine concentrations, and that these effects were sex dependent. CORT drug alcohol 23827168 Following 2 weeks of experience with each schedule, blood samples were collected at the conclusion of the last 60 min session to evaluate CORT and the blood ethanol concentration (BEC) achieved. CORT addiction aversion 23827168 In contrast, CORT levels rose monotonically with incremental increases in the FT interval regardless of the strain examined or fluid type offered, indicating that glucocorticoid release likely reflects the aversive aspects of increasing intervals between reinforcement rather than engagement in adjunctive behavior.

CORT drug amphetamine 23727174 Enriched environments decreased the response to AMPH and stress induced CORT regardless of trait but selectively decreased pTrkB and increased D2 mRNA levels in high anxiety animals. CORT drug alcohol 23643750 To model a period of heightened elevations in CORT, the present work assessed the effects of chronic exposure to the stress hormone CORT on alcohol self administration. CORT addiction reward 23643750 Following stable baseline operant self administration, rats received CORT in the drinking water for 7 days. CORT drug alcohol 23643750 A transient increase in alcohol self administration was observed on the first self administration session following CORT exposure, and behavior returned to control levels by the second session. CORT drug alcohol 23643750 Control experiments determined that this increase in alcohol self administration was specific to alcohol, unrelated to general motor activation, and functionally dissociated from decreased CORT levels at the time of testing. CORT drug alcohol 23643750 Given that maladaptive drinking patterns, such as escalated alcohol drinking following stressful episodes, have the potential to put an individual at risk for future drinking disorders, utilization of this model will be important for examination of neuroadaptations that occur as a consequence of CORT exposure in order to better understand escalated drinking following stressful episodes in nondependent individuals. CORT drug cocaine 23212389 Furthermore, 20 mg/kg nor BNI reduced both the locomotor response to cocaine on Test 2 and the effect of cocaine and food restriction on CORT plasma levels. CORT addiction intoxication 22500955 Using a rat model of binge like intoxication, we tested whether elevated corticosterone (Cort) levels contribute to the neurotoxic consequences of EtOH exposure. CORT drug alcohol 22500955 Basal Cort replacement concentrations in EtOH treated Adx animals did not exacerbate alcohol induced neurodegeneration in the hippocampal dentate gyrus (DG) or the entorhinal cortex (EC) as observed by amino cupric silver staining. CORT drug alcohol 22384198 Our results showed that acute and repeated binge pattern alcohol treatment increased plasma ACTH and CORT levels in both E(2) and Ch treated groups, however habituation to repeated binge pattern alcohol exposure was evident only in E(2) treated animals. CORT addiction intoxication 22384198 Our results showed that acute and repeated binge pattern alcohol treatment increased plasma ACTH and CORT levels in both E(2) and Ch treated groups, however habituation to repeated binge pattern alcohol exposure was evident only in E(2) treated animals. CORT addiction sensitization 22333290 Because CRF/CRF₁ initiate EtOH induced activation of the hypothalamic pituitary adrenal axis, we investigated CORT effects on EtOH sensitization. CORT addiction sensitization 22333290 The CORT synthesis inhibitor metyrapone prevented the acquisition, but not the expression, of EtOH sensitization. CORT addiction sensitization 22333290 Exogenous CORT administration sensitized the locomotor response to a subsequent EtOH challenge; we observed, however, that the exogenous CORT levels necessary to induce sensitization to EtOH were significantly higher than those produced by EtOH treatment. CORT addiction sensitization 22333290 Therefore, participation of CORT seems to be necessary, but not sufficient, to explain the role of CRF/CRF₁ in the acquisition of sensitization to EtOH. CORT drug cocaine 22309318 Oxytocin and corticosterone (CORT) interact to mediate hormonal stress responses and can be altered by cocaine use. CORT drug alcohol 22051944 The 0.5g/kg ethanol dose did not affect plasma corticosterone (CORT) measured 5h after maternal separation or 20min after ethanol injection. CORT drug alcohol 22016195 Given that interoceptive/subjective drug cues are a fundamental factor in drug taking behavior, we sought to determine the effects of exposure to repeated elevations in the glucocorticoid corticosterone (CORT) on the interoceptive effects of alcohol in rats using drug discrimination techniques. CORT drug alcohol 22016195 Male Long Evans rats trained to discriminate alcohol (1 g/kg, IG) vs. water were exposed to CORT (300 μg/ml) in the home cage drinking water for 7 days. CORT drug alcohol 22016195 The interoceptive effects of experimenter and self administered alcohol were blunted following CORT. CORT addiction relapse 21863233 Levels of reinstatement and plasma corticosterone (CORT) were determined each week for four consecutive weeks. CORT drug alcohol 21863233 Plasma CORT levels in response to injection of both vehicle and yohimbine were significantly higher in the ethanol trained animals compared to sucrose controls. CORT addiction sensitization 21792578 It has been shown in some studies that the rise in corticosterone (CORT) concentration is indispensable for both the induction and the expression of behavioral sensitization. CORT drug amphetamine 21792578 Therefore, it might be suspected that behavioral hyposensitivity to amphetamine (AMPH) is somehow related to a reduced CORT response to the psychostimulant subsequent to the chlorphenvinphos (CVP) intoxication. CORT addiction intoxication 21792578 Therefore, it might be suspected that behavioral hyposensitivity to amphetamine (AMPH) is somehow related to a reduced CORT response to the psychostimulant subsequent to the chlorphenvinphos (CVP) intoxication. CORT drug amphetamine 21792578 2) Three weeks after the CVP exposure, the CORT response to AMPH was significantly increased. CORT drug alcohol 21533237 Our previous studies showed that binge pattern ethanol (EtOH) treatment during pubertal development negatively dysregulated the responsiveness of the hypothalamo pituitary adrenal (HPA) axis, as manifested by alterations in corticotrophin releasing hormone (CRH), arginine vasopressin (AVP), and corticosterone (CORT) during this time period. CORT addiction intoxication 21533237 Our previous studies showed that binge pattern ethanol (EtOH) treatment during pubertal development negatively dysregulated the responsiveness of the hypothalamo pituitary adrenal (HPA) axis, as manifested by alterations in corticotrophin releasing hormone (CRH), arginine vasopressin (AVP), and corticosterone (CORT) during this time period. CORT drug nicotine 21396990 Hypothalamic pituitary adrenal (HPA) responses to single dose nicotine (NIC) are sexually diergic: Female rats have higher adrenocorticotropic hormone (ACTH) and corticosterone (CORT) responses than do males. CORT drug alcohol 21309957 Pre treatment with SoRI 9409 decreased yohimbine stress induced reinstatement of ethanol seeking but did not affect yohimbine induced increases in plasma CORT levels. CORT addiction relapse 21309957 Pre treatment with SoRI 9409 decreased yohimbine stress induced reinstatement of ethanol seeking but did not affect yohimbine induced increases in plasma CORT levels. CORT drug amphetamine 20713076 We examined the habituation of exploratory movement, amphetamine (AMPH) induced motor activity, as well as changes in serum corticosterone (CORT) and glucose levels. CORT drug psychedelics 20634423 Although chronic unpredictable stress (CUS) enhances the acute hyperthermic and long term monoamine depleting effects of the psychostimulant +3,4 methylenedioxymethamphetamine (MDMA), the roles of hyperthermia and corticosterone (CORT) in mediating the stress induced enhancement of MDMA induced serotonin (5 HT) and dopamine (DA) depletions are unknown. CORT drug psychedelics 20634423 Prior exposure to CUS augmented MDMA induced hyperthermia and plasma CORT secretion and the long term depletions in 5 HT content in striatum, hippocampus, and frontal cortex and DA content in striatum. CORT drug psychedelics 20634423 A reduced ambient temperature of 21°C attenuated the hyperthermia, CORT secretion, and 5 HT decreases after MDMA in nonstressed rats. CORT drug psychedelics 20634423 The lower ambient temperature also prevented the augmented hyperthermia, CORT secretion, and enhanced 5 HT and DA depletions after MDMA in chronically stressed rats to levels exhibited by nonstressed, MDMA treated rats. CORT drug psychedelics 20634423 To investigate the role of CORT on monoamine depletions in response to MDMA, stressed and nonstressed rats were treated with the CORT synthesis inhibitor metyrapone during exposure to MDMA. CORT drug psychedelics 20634423 This study suggests that enhanced CORT is a consequence of enhanced hyperthermia and the CUS induced enhancements of MDMA induced monoamine depletions may be mediated by hyperthermia but not CORT. CORT drug alcohol 19952347 Our results showed that ethanol increased plasma corticosterone (CORT) levels in both sexes, yet binge treated animals had significantly lower CORT levels than animals exposed to a single dose, suggesting that the hypothalamo pituitary adrenal (HPA) axis habituated to the repeated stressful stimuli of ethanol. CORT addiction intoxication 19952347 Our results showed that ethanol increased plasma corticosterone (CORT) levels in both sexes, yet binge treated animals had significantly lower CORT levels than animals exposed to a single dose, suggesting that the hypothalamo pituitary adrenal (HPA) axis habituated to the repeated stressful stimuli of ethanol. CORT drug amphetamine 19879056 Therefore the objective of these studies was to determine if 10 days of chronic unpredictable stress modulates corticosterone (CORT) responses to methamphetamine and furthermore how chronic stress may modulate methamphetamine induced increases in hyperthermia and CORT. CORT drug amphetamine 19879056 As chronic stress potentiates hyperthermic responses to serotonin 2 (5 HT2) stimulation and 5 HT2 receptors are important in mediating both hyperthermic and CORT responses, we also investigated if 5 HT2 antagonism would block hyperthermia and CORT secretion by the serial exposure to stress and methamphetamine (stress/methamphetamine). CORT drug amphetamine 19879056 The results of these studies illustrate that stress potentiates methamphetamine induced increases in body temperature and CORT secretion and that these increases are blocked by the 5 HT2 antagonist ketanserin. CORT drug opioid 19179436 This study addressed the role of morphine withdrawal induced corticosterone (CORT) release in regulation of tyrosine hydroxylase (TH), the rate limiting enzyme of catecholamine biosynthesis in adrenalectomized (ADX) rats supplemented with low CORT pellet (ADX plus CORT). CORT addiction withdrawal 19179436 This study addressed the role of morphine withdrawal induced corticosterone (CORT) release in regulation of tyrosine hydroxylase (TH), the rate limiting enzyme of catecholamine biosynthesis in adrenalectomized (ADX) rats supplemented with low CORT pellet (ADX plus CORT). CORT drug opioid 19179436 However, this induction of TH expression is not detected in ADX plus CORT rats that are unable to mount CORT secretory response to morphine withdrawal. CORT addiction withdrawal 19179436 However, this induction of TH expression is not detected in ADX plus CORT rats that are unable to mount CORT secretory response to morphine withdrawal. CORT drug opioid 19179436 Total TH protein levels were elevated in the NTS A(2) from sham operated rats during morphine dependence and withdrawal, whereas we did not find any alteration in ADX plus CORT animals. CORT addiction dependence 19179436 Total TH protein levels were elevated in the NTS A(2) from sham operated rats during morphine dependence and withdrawal, whereas we did not find any alteration in ADX plus CORT animals. CORT addiction withdrawal 19179436 Total TH protein levels were elevated in the NTS A(2) from sham operated rats during morphine dependence and withdrawal, whereas we did not find any alteration in ADX plus CORT animals. CORT drug opioid 19179436 However, induction of morphine withdrawal to ADX plus CORT animals did not alter the phosphorylation (activation) of TH in NTS A(2) and decreased TH activity in the PVN. CORT addiction withdrawal 19179436 However, induction of morphine withdrawal to ADX plus CORT animals did not alter the phosphorylation (activation) of TH in NTS A(2) and decreased TH activity in the PVN. CORT drug alcohol 18945222 Blood alcohol content (BAC) and corticosterone (CORT) content were analyzed in a separate series of intact and GDX males and females with and without ADX in response to the EtOH challenge. CORT drug amphetamine 18614766 Body weight (BW), blood pressure (BP), fluid intake, salt preference, response to amphetamine, open field behavior, plasma adrenocorticotropin hormone (ACTH), plasma corticosterone (Cort), and adrenal gland weight were measured. CORT drug alcohol 18279498 The objectives of this paper are to examine the prolactin (PRL) and CORT response to dl fenfluramine in a large cohort of males with alcohol dependence who had been abstinent for 3 weeks, and to compare this with an age matched control group. CORT addiction dependence 18279498 The objectives of this paper are to examine the prolactin (PRL) and CORT response to dl fenfluramine in a large cohort of males with alcohol dependence who had been abstinent for 3 weeks, and to compare this with an age matched control group. CORT drug alcohol 18279498 CORT response was significantly lower in abstinent alcoholics than in controls (F = 10.0, d.f. CORT drug alcohol 18279498 The reduced CORT response in abstinent alcoholics further supports evidence of hypofunction of the adrenocortical system in this group. CORT drug alcohol 18218724 Mood, craving for alcohol, and salivary cortisol levels (CORT) were measured before and after tryptophan and after stress induction. CORT addiction relapse 18218724 Mood, craving for alcohol, and salivary cortisol levels (CORT) were measured before and after tryptophan and after stress induction. CORT drug alcohol 18218724 Stress increased CORT, HR, negative mood, and craving for alcohol. CORT addiction relapse 18218724 Stress increased CORT, HR, negative mood, and craving for alcohol. CORT drug alcohol 18218724 Among heavy drinkers HiHs report higher craving for alcohol and show greater reactivity to stress as measured by CORT and negative mood. CORT addiction relapse 18218724 Among heavy drinkers HiHs report higher craving for alcohol and show greater reactivity to stress as measured by CORT and negative mood. CORT drug cocaine 17689506 Cocaine self administering rats displayed reduced basal plasma corticosterone (CORT) levels but showed an augmented restraint induced percent increase response from baseline compared to saline self administering controls when measured 24 days after SA testing. CORT drug cocaine 17689506 This augmented CORT response may have been attributable to impaired glucocorticoid receptor (GR) mediated feedback regulation of HPA function, since cocaine self administering rats were also less susceptible to dexamethasone (0.01 mg/kg, i.p.) CORT addiction sensitization 17675171 In males, LMS and BMS increased the CORT response to EtOH but did not modify behavioural sensitization. CORT addiction sensitization 17675171 Therefore, we postulate that LMS female mice exhibited a faster development of behavioural sensitization, but CORT levels were not involved with this effect. CORT drug opioid 17654090 The purpose of this study was to determine the morphine induced place preference in rats pre exposed to footshock stress and corticosterone (CORT). CORT drug opioid 17654090 The results showed that chronic footshock or CORT exposure but not acute footshock or CORT exposure similarly potentiated the conditioned place preference to morphine. CORT drug opioid 17654090 The findings suggest that the increase of dopamine levels in NAc induced by CORT might be the medium between stress and morphine. CORT drug alcohol 17561882 To investigate the role of the Avpr1b in the HPA axis response to acute stress, we measured ACTH and corticosterone (CORT) plasma levels in Avpr1b knockout (KO) mice and wild type controls in response to bacterial lipopolysaccharide (LPS) challenge and ethanol (EtOH) administration. CORT addiction addiction 17534378 A surgical adrenalectomy and corticosterone replacement (ADX/C) regimen that eliminated SA induced increases in corticosterone (CORT) while maintaining the diurnal pattern of secretion failed to alter SA or reinstatement in ShA rats but slowed escalation and attenuated later reinstatement in LgA rats when applied before but not after chronic LgA SA testing. CORT addiction relapse 17534378 A surgical adrenalectomy and corticosterone replacement (ADX/C) regimen that eliminated SA induced increases in corticosterone (CORT) while maintaining the diurnal pattern of secretion failed to alter SA or reinstatement in ShA rats but slowed escalation and attenuated later reinstatement in LgA rats when applied before but not after chronic LgA SA testing. CORT drug cocaine 17534378 The inability of daily CORT administration before daily ShA SA, at a dose that reproduced the response during LgA SA, to mimic the effects of LgA SA suggests that elevated glucocorticoids during SA may play a permissive role in cocaine induced neuroplasticity that contributes to addiction. CORT addiction addiction 17534378 The inability of daily CORT administration before daily ShA SA, at a dose that reproduced the response during LgA SA, to mimic the effects of LgA SA suggests that elevated glucocorticoids during SA may play a permissive role in cocaine induced neuroplasticity that contributes to addiction. CORT drug amphetamine 17460357 METH increases plasma corticosterone (CORT) in both strains. CORT drug amphetamine 17460357 However, the intensity of increment of CORT by repeated METH was lower in LE rats than that in WIS rats. CORT drug amphetamine 17460357 Repeated METH treatment decreased the expression of METH transposable and CORT sensitive transporter, organic cation transporter 3 (OCT3), in the brain of WIS rats. CORT drug amphetamine 17460357 Taken together, these results suggest that the lack of establishment of BS in LE rats might have been caused by the unchanged brain penetration of METH after repeated METH administration, and that the differential CORT response to METH is an important strain difference. CORT drug cocaine 17293045 Basal CORT was also unaffected by prior cocaine administration, but the CORT response measured immediately after restraint was significantly augmented in cocaine withdrawn rats. CORT drug amphetamine 17244944 Plasma CORT level, highly elevated by AMPH (+337 Delta %), was attenuated nearly by 50% under beta adrenergic blockade. CORT drug amphetamine 17129610 During the experimental task, ACTH and CORT increased significantly less in METH patients than in BUP patients and CONT. CORT addiction intoxication 16707557 To further delineate the mechanism of impaired intestinal barrier function, the present study examined the role of corticosterone (CORT) and interleukin (IL) 18, as CORT and IL 18 are elevated following a combined insult of EtOH intoxication and burn injury. CORT addiction intoxication 16707557 These findings suggest that a combined insult of EtOH and burn injury results in increased CORT levels, which in turn up regulates intestinal IL 18 levels and thereby causes altered intestinal barrier function following a combined insult of EtOH intoxication and burn injury. CORT addiction addiction 16641943 Surgical adrenalectomy along with diurnal corticosterone (CORT) replacement prevented EFS induced escalation without altering SA in the absence of EFS, indicating that increases in circulating glucocorticoids were necessary for the escalating effects of EFS. CORT drug cocaine 16641943 failed to reproduce the effects of repeated daily EFS on SA, but restored the escalating effects of EFS in adrenalectomized rats with CORT replacement, suggesting that an elevation of glucocorticoids was necessary but alone was not sufficient for the escalation of cocaine SA by EFS. CORT addiction addiction 16641943 failed to reproduce the effects of repeated daily EFS on SA, but restored the escalating effects of EFS in adrenalectomized rats with CORT replacement, suggesting that an elevation of glucocorticoids was necessary but alone was not sufficient for the escalation of cocaine SA by EFS. CORT drug opioid 16584846 We have previously shown that the CORT response to morphine, but not to a previous uncontrollable stressor, is necessary for the stress induced potentiation of morphine's rewarding effects. CORT drug opioid 16584846 Here, we test (1) the necessity of CORT during inescapable stress (IS) and/or morphine for IS potentiation of morphine induced NAcs DA and (2) the sufficiency of enhanced CORT, in the absence of prior IS, to potentiate morphine induced NAcs DA as well as morphine conditioned place preference (CPP) in male Sprague Dawley rats. CORT addiction reward 16584846 Here, we test (1) the necessity of CORT during inescapable stress (IS) and/or morphine for IS potentiation of morphine induced NAcs DA and (2) the sufficiency of enhanced CORT, in the absence of prior IS, to potentiate morphine induced NAcs DA as well as morphine conditioned place preference (CPP) in male Sprague Dawley rats. CORT drug opioid 16584846 In the first experiment, we administered the CORT synthesis inhibitors metyrapone and aminoglutethimide (100mg/kg each, sc) to suppress the CORT response to either IS (100 1 mA tailshocks) or subsequent morphine (3 mg/kg, sc) treatment. CORT drug opioid 16584846 In the next experiments, CORT (1 mg/kg, sc) was injected 20 or 30 min before morphine during either microdialysis or CPP testing, respectively, in non stressed rats. CORT addiction reward 16584846 In the next experiments, CORT (1 mg/kg, sc) was injected 20 or 30 min before morphine during either microdialysis or CPP testing, respectively, in non stressed rats. CORT drug opioid 16584846 We found that IS potentiated subsequent morphine induced NAcs DA and this was completely blocked by CORT suppression before morphine, but not before IS. CORT drug opioid 16584846 However, elevated levels of CORT concurrent with morphine, but in the absence of a stressor, failed to potentiate NAcs DA or CPP. CORT addiction reward 16584846 However, elevated levels of CORT concurrent with morphine, but in the absence of a stressor, failed to potentiate NAcs DA or CPP. CORT drug opioid 16584846 These results suggest that the CORT response to morphine is necessary, but not sufficient in the absence of prior IS, for sensitized NAcs DA and CPP responding to morphine, and provide further evidence that CORT is involved in the expression, but not the induction, of this sensitization. CORT addiction reward 16584846 These results suggest that the CORT response to morphine is necessary, but not sufficient in the absence of prior IS, for sensitized NAcs DA and CPP responding to morphine, and provide further evidence that CORT is involved in the expression, but not the induction, of this sensitization.

CORT drug amphetamine 16563358 The aim of the present study was to investigate stress and AMPH induced release of adrenocorticotropic hormone (ACTH) and corticosterone (CORT) during withdrawal from an escalating dosage schedule of AMPH known to produce depression like effects in rats. CORT addiction withdrawal 16563358 The aim of the present study was to investigate stress and AMPH induced release of adrenocorticotropic hormone (ACTH) and corticosterone (CORT) during withdrawal from an escalating dosage schedule of AMPH known to produce depression like effects in rats. CORT drug amphetamine 16563358 We found no effect of AMPH withdrawal in the Porsolt swim test and on the ACTH or CORT response following restraint stress. CORT addiction withdrawal 16563358 We found no effect of AMPH withdrawal in the Porsolt swim test and on the ACTH or CORT response following restraint stress. CORT drug amphetamine 16563358 AMPH withdrawn animals expressed behavioral sensitization in terms of locomotion and reduced ACTH and CORT plasma levels following a 1 mg/kg AMPH challenge in comparison to the controls. CORT addiction sensitization 16563358 AMPH withdrawn animals expressed behavioral sensitization in terms of locomotion and reduced ACTH and CORT plasma levels following a 1 mg/kg AMPH challenge in comparison to the controls. CORT drug opioid 15821955 First, the CORT response to 3.0 mg/kg morphine was measured in male Sprague Dawley rats 24 h following exposure to IS. CORT drug opioid 15821955 Finally, we used the temporary CORT synthesis inhibitors metyrapone and aminoglutethimide to determine the necessity of CORT rises during either IS or morphine administration on the potentiated CPP response. CORT addiction reward 15821955 Finally, we used the temporary CORT synthesis inhibitors metyrapone and aminoglutethimide to determine the necessity of CORT rises during either IS or morphine administration on the potentiated CPP response. CORT drug opioid 15821955 Prior IS significantly potentiated the CORT response to morphine. CORT drug opioid 15821955 However, CORT inhibition during IS had no effect on the IS potentiation of morphine CPP, whereas inhibition during morphine administration completely blocked this potentiation. CORT addiction reward 15821955 However, CORT inhibition during IS had no effect on the IS potentiation of morphine CPP, whereas inhibition during morphine administration completely blocked this potentiation. CORT drug opioid 15821955 The results indicate that the CORT response to morphine is enhanced in rats that were previously exposed to an uncontrollable stressor, and that this response to the drug, not the stressor, is necessary for the stress enhanced potentiation of morphine CPP. CORT addiction reward 15821955 The results indicate that the CORT response to morphine is enhanced in rats that were previously exposed to an uncontrollable stressor, and that this response to the drug, not the stressor, is necessary for the stress enhanced potentiation of morphine CPP. CORT addiction intoxication 15718389 In this study, we examined whether corticosterone (Cort) plays any role in suppressing MLN T cell function and bacterial accumulation after EtOH intoxication and burn injury. CORT addiction intoxication 15718389 Two days after injury, a significant increase in blood Cort levels and suppression of MLN T cell proliferation and IL 2 production was observed in rats receiving combined insult of EtOH intoxication and burn injury compared with rats receiving EtOH intoxication or burn injury alone. CORT addiction intoxication 15718389 These findings suggest that EtOH intoxication before burn injury augments Cort release, which suppresses MLN T cell function by inhibiting p38 and ERK1/2 activation and promotes bacterial accumulation in MLN after EtOH and burn injury. CORT drug alcohol 15369760 Specifically, alcohol acts as a crucial regulator of the hypothalamic pituitary adrenal (HPA) axis, thereby modulating the release of hormones, particularly adrenocorticotropic hormone (ACTH) and corticosterone (CORT). CORT drug opioid 14687867 During the experimentally induced aggressiveness, plasma adrenocorticotropic hormone (ACTH) and cortisol (CORT) concentrations increased less significantly, and norepinephrine (NE) and epinephrine (EPI) levels, together with heart rate (HR), increased more significantly in abstinent heroin dependent subjects than in healthy subjects. CORT drug opioid 14687867 PSAP aggressive responses positively correlated with catecholamine changes, BDHI "direct" and "irritability" scores, MMPI "psychopathic deviate" scores in heroin dependent subjects and controls, and with CORT responses only in healthy subjects. CORT drug alcohol 12920386 Withdrawal symptoms, mood changes, cardiovascular indexes (heart rate, blood pressure), norepinephrine (NE), epinephrine (EPI), adrenocorticotropic hormone (ACTH) and cortisol (CORT) were evaluated during naloxone naltrexone administration on the second day of detoxification treatment. CORT drug opioid 12920386 Withdrawal symptoms, mood changes, cardiovascular indexes (heart rate, blood pressure), norepinephrine (NE), epinephrine (EPI), adrenocorticotropic hormone (ACTH) and cortisol (CORT) were evaluated during naloxone naltrexone administration on the second day of detoxification treatment. CORT addiction withdrawal 12920386 Withdrawal symptoms, mood changes, cardiovascular indexes (heart rate, blood pressure), norepinephrine (NE), epinephrine (EPI), adrenocorticotropic hormone (ACTH) and cortisol (CORT) were evaluated during naloxone naltrexone administration on the second day of detoxification treatment. CORT drug opioid 12920386 Slight and transient withdrawal symptoms and mood changes were demonstrated on the second day in the whole sample of patients, in association with a significant, but moderate, elevation of heart rate, blood pressure, NE (two fold), EPI (five fold), ACTH (two fold) and CORT (two fold) plasma levels, in response to opioid receptor antagonist administration. CORT addiction withdrawal 12920386 Slight and transient withdrawal symptoms and mood changes were demonstrated on the second day in the whole sample of patients, in association with a significant, but moderate, elevation of heart rate, blood pressure, NE (two fold), EPI (five fold), ACTH (two fold) and CORT (two fold) plasma levels, in response to opioid receptor antagonist administration. CORT drug cocaine 12892653 The purpose of the present study was to investigate the effects of 14 days of ShA or LgA, high dose cocaine SA on plasma corticosterone (CORT), prolactin (PRL), and related mRNAs. CORT drug cocaine 12892653 Acutely, cocaine SA increased plasma CORT and reduced plasma PRL levels. CORT drug cocaine 12892653 SA training produced circadian increases in CORT that appeared to occur in anticipation of cocaine availability. CORT drug cocaine 12892653 With repeated LgA, high dose SA, the daily CORT area under the curve (AUC) progressively decreased, apparently due to tolerance to cocaine's effects on CORT and a reduction in basal CORT levels. CORT drug amphetamine 12576877 ESC and INT AMPH withdrawal had no effect on any of these tests or on stress responsiveness as measured by increased plasma levels of corticosterone (CORT) and adrenocorticotropin following the swim test, although basal CORT levels were higher in AMPH withdrawn animals compared to controls. CORT addiction withdrawal 12576877 ESC and INT AMPH withdrawal had no effect on any of these tests or on stress responsiveness as measured by increased plasma levels of corticosterone (CORT) and adrenocorticotropin following the swim test, although basal CORT levels were higher in AMPH withdrawn animals compared to controls. CORT addiction sensitization 11850143 The main purpose the present study was, therefore, to determine the effects of psychostimulant cross sensitization on the stress induced release of adrenocorticotropic hormone (ACTH) and corticosterone (CORT). CORT drug amphetamine 11850143 Prior d amphetamine had no effect upon levels of CORT and ACTH in the non stressed animals. CORT drug amphetamine 11850143 A second experiment confirmed behavioral sensitization to the current schedule of d amphetamine injections, and demonstrated neuroendocrine sensitization of ACTH and CORT to a subsequent drug challenge. CORT addiction sensitization 11850143 A second experiment confirmed behavioral sensitization to the current schedule of d amphetamine injections, and demonstrated neuroendocrine sensitization of ACTH and CORT to a subsequent drug challenge. CORT drug amphetamine 11850143 The augmented release of CORT and ACTH observed in d amphetamine treated rats might have important implications for human disorders in which processes resembling neurochemical sensitization have been hypothesized to play an etiological role.

CORT addiction withdrawal 11797058 Regional brain CRF like immunoreactivity (CRF LI), plasma ACTH LI and CORT LI levels were determined from 1 day to 6 weeks post withdrawal. CORT drug alcohol 11797058 Ethanol withdrawn rats also initially had reduced hippocampal, frontal cortical and hypothalamic CRF LI levels and time dependent reductions in basal CORT levels. CORT drug cocaine 11797058 Cocaine withdrawn rats showed time dependent elevations in frontal cortical CRF LI and basal CORT levels. CORT drug alcohol 11797058 Protracted withdrawal from ethanol or cocaine is associated with altered limbic CRF LI and circulating CORT levels beyond the detoxification stage. CORT drug cocaine 11797058 Protracted withdrawal from ethanol or cocaine is associated with altered limbic CRF LI and circulating CORT levels beyond the detoxification stage. CORT addiction withdrawal 11797058 Protracted withdrawal from ethanol or cocaine is associated with altered limbic CRF LI and circulating CORT levels beyond the detoxification stage. CORT drug cocaine 11512040 Novelty induced (but not cocaine induced) locomotor activity, pre SA plasma CORT, and pre SA food reinforced lever pressing predicted SA, but only at the lowest cocaine dose tested. CORT drug cocaine 10898093 Effects of adrenalectomy (ADX) and corticosterone (CORT) on the development and expression of sensitization to the locomotor effect of cocaine (COC) were studied in rats. CORT addiction sensitization 10898093 Effects of adrenalectomy (ADX) and corticosterone (CORT) on the development and expression of sensitization to the locomotor effect of cocaine (COC) were studied in rats. CORT addiction sensitization 10898093 Pretreatment with CORT, 10 mg/kg, but not 5 mg/kg, before each of the 5 daily COC injections facilitated the development of COC sensitization, tested after a 5 day withdrawal. CORT addiction withdrawal 10898093 Pretreatment with CORT, 10 mg/kg, but not 5 mg/kg, before each of the 5 daily COC injections facilitated the development of COC sensitization, tested after a 5 day withdrawal. CORT addiction sensitization 10898093 When pretreated with CORT alone (10 mg/kg), the challenge dose of COC administered on day 10 induced cross sensitization to CORT. CORT addiction sensitization 10898093 CORT (10 mg/kg) injected acutely before COC on day 10, potentiated the expression of COC sensitization. CORT addiction sensitization 10898093 Our results indicate that CORT facilitates the development and expression of COC sensitization, while ADX blocks the initiation of the behavioral phenomenon only. CORT addiction sensitization 10898093 Moreover, there takes place cross sensitization between CORT and COC, which indicates a close relationship between the drug related mechanism and behavioral sensitization. CORT drug cocaine 10871318 cocaine self administration under "naturalistic" conditions on plasma corticosterone (CORT) and prolactin (PRL) were investigated in male Sprague Dawley rats. CORT drug cocaine 10871318 After the determination of plasma CORT and PRL levels under basal conditions before access to cocaine for self administration, rats were allowed to self administer cocaine (0.25, 0.5, 1.0, or 2.0 mg/kg/infusion i.v.) CORT drug cocaine 10871318 The effects of cocaine on plasma CORT were intake dependent, as demonstrated by significant positive correlations between postsession plasma CORT and total cocaine intake within the preceding sessions. CORT drug psychedelics 10664829 Prolactin (PRL) and cortisol (CORT) responses to the serotonergic agonist d fenfluramine (D fen), clinical psychobehavioral changes, and psychometric measures were evaluated 3 weeks and then 12 months after MDMA discontinuation. CORT drug psychedelics 10664829 MDMA users showed significantly reduced PRL and CORT responses in comparison with control subjects at 3 weeks (respectively, p < .001; p < .005). CORT drug psychedelics 10664829 In contrast, CORT responses in MDMA users were restored after 12 months of abstinence, with significantly higher responses to D fen, in comparison with 3 week responses (p < .05). CORT drug psychedelics 10664829 CORT restored responses to D fen at 12 months, and the correlation of neuroendocrine changes with MDMA exposure suggest that the neuroendocrine impairment may be due to a partially reversible neurotoxic action of MDMA on the human brain. CORT drug amphetamine 10654663 AMPH exerted a paradoxical effect on CORT secretion only in maternally deprived subjects while affecting behaviour mainly in deprived female subjects, which showed a generalised shift to the left in the dose response curve to this drug. CORT drug alcohol 10642377 Ethanol did not increase circulating epinephrine, norepinephrine, or cortisol concentration (Cort) above Ex elevations. CORT drug alcohol 10642377 It is concluded that, although this blood ethanol concentration is insufficient to acutely increase Cort above that caused by Ex alone, it appears that ethanol may have a prolonged effect beyond the Ex response. CORT drug opioid 10475168 Since these modulatory effects of stress on the locomotor effects of morphine might be mediated via the release of endogenous corticosteroids we also tested the influence of repeated intermittent and chronic administration of corticosterone (CORT) and the synthetic corticosteroid dexamethasone (DEX) on the locomotor response to morphine. CORT drug opioid 10475168 Further, stress induced CORT release seems to be involved in stress induced behavioural sensitization to morphine. CORT addiction sensitization 10475168 Further, stress induced CORT release seems to be involved in stress induced behavioural sensitization to morphine. CORT drug alcohol 10069560 We tested the hypothesis that prenatal ethanol exposure would result in increased plasma corticosterone (CORT) and adrenocorticotropin (ACTH) responses and increased peptide [corticotropin releasing factor and vasopressin] mRNA levels in the paraventricular nucleus (PVN) of the hypothalamus compared to that in control animals. CORT addiction sensitization 10069560 Sensitization of the CORT response to acute stress was observed in males but not females across all prenatal treatment groups. CORT drug cocaine 9822801 In order to test this hypothesis, the effects of long term (3 and 6 weeks) 'binge' pattern cocaine administration (3x15 mg/kg cocaine, i.p., daily, during the early phase of the light cycle) on body weight, adrenal gland weight, basal and stress induced activity of the corticosterone (CORT) and basal plasma testosterone (T) levels were measured. CORT addiction intoxication 9822801 In order to test this hypothesis, the effects of long term (3 and 6 weeks) 'binge' pattern cocaine administration (3x15 mg/kg cocaine, i.p., daily, during the early phase of the light cycle) on body weight, adrenal gland weight, basal and stress induced activity of the corticosterone (CORT) and basal plasma testosterone (T) levels were measured. CORT drug cocaine 9822801 Both 3 and 6 weeks 'binge' cocaine administration decreased body weight gain, increased the weight of adrenal glands and increased basal CORT levels. CORT addiction intoxication 9822801 Both 3 and 6 weeks 'binge' cocaine administration decreased body weight gain, increased the weight of adrenal glands and increased basal CORT levels. CORT drug cocaine 9822801 Neither chronic saline nor cocaine administration altered stress induced CORT secretion. CORT drug cocaine 9822801 CORT levels 60 min following the restraint stress (recovery) were significantly lower than pre stress basal levels after 3 and 6 weeks of cocaine, but not saline, administration. CORT drug cocaine 9554945 Elevated blood concentrations of corticosterone (CORT), an adrenal steroid associated with stress responses, is one of the endocrine correlates of cocaine treatment. CORT drug cocaine 9554945 ), on the test day, prior to exposure to cocaine associated contextual cues, attenuated the subsequent conditioned increase in blood CORT concentrations. CORT drug cocaine 9554945 Because the hypothalamic pituitary adrenal (HPA) axis has been implicated in modulating the actions of cocaine, it is plausible that such conditioned increases in CORT release by cocaine associated cues may further predispose an organism to the reinforcing effects of the drug or enhance the susceptibility to drug taking behavior. CORT addiction reward 9554945 Because the hypothalamic pituitary adrenal (HPA) axis has been implicated in modulating the actions of cocaine, it is plausible that such conditioned increases in CORT release by cocaine associated cues may further predispose an organism to the reinforcing effects of the drug or enhance the susceptibility to drug taking behavior. CORT addiction sensitization 9537679 To determine if a similar phenomenon occurred with stress induced sensitization, male Sprague Dawley rats were given a sham ADX, ADX surgery, or ADX plus s.c. implanted corticosterone (CORT) pellets (CORT 12.5% pellets or CORT 50% pellets). CORT drug cocaine 9537679 Animals given ADX surgery or ADX and CORT 12.5% pellets did not demonstrate sensitization to repeated stress, while CORT 50% pellets in ADX rats restored the sensitized horizontal response to cocaine challenge at late withdrawal. CORT addiction sensitization 9537679 Animals given ADX surgery or ADX and CORT 12.5% pellets did not demonstrate sensitization to repeated stress, while CORT 50% pellets in ADX rats restored the sensitized horizontal response to cocaine challenge at late withdrawal. CORT addiction withdrawal 9537679 Animals given ADX surgery or ADX and CORT 12.5% pellets did not demonstrate sensitization to repeated stress, while CORT 50% pellets in ADX rats restored the sensitized horizontal response to cocaine challenge at late withdrawal. CORT drug cocaine 9537679 In contrast, stress pretreated rats which were given CORT 50% pellets during the 2 week withdrawal period after the stress showed a marked decrease in horizontal activity in response to cocaine challenge at late withdrawal. CORT addiction withdrawal 9537679 In contrast, stress pretreated rats which were given CORT 50% pellets during the 2 week withdrawal period after the stress showed a marked decrease in horizontal activity in response to cocaine challenge at late withdrawal. CORT drug cocaine 9537679 Together with our previous study on the role of CORT in cocaine induced sensitization, the results indicate that CORT is not the common factor mediating the long term sensitization to cocaine and stress. CORT addiction sensitization 9537679 Together with our previous study on the role of CORT in cocaine induced sensitization, the results indicate that CORT is not the common factor mediating the long term sensitization to cocaine and stress. CORT drug cocaine 9406871 CORT levels were higher in cocaine versus saline treated animals (P < 0.01). CORT drug nicotine 7870994 Other investigators have suggested that tolerance to multiple nicotine injections in mice may be due, in part, to elevated plasma corticosterone (CORT) levels, since repeated nicotine injections are associated with elevated CORT, chronically elevated CORT reduces nicotine responsiveness and adrenalectomy disrupts nicotine tolerance. CORT drug nicotine 7870994 Three experiments tested the feasibility of this hypothesis, as a mechanism for conditioned nicotine tolerance in rats, by determining whether acute administration of CORT or manipulations that increase adrenocortical activity reduce nicotine responsiveness. CORT drug nicotine 7870994 In experiment 1, male rats were injected IP with CORT (1 mg/kg), vehicle (ETOH + distilled water) or no injection 10 min before nicotine (0.75 mg/kg, SC) and tested for nicotine induced analgesia every other day for 10 days. CORT drug nicotine 7870994 A significant reduction in withdrawal latencies was obtained for CORT pretreated rats compared to animals given only nicotine. CORT addiction withdrawal 7870994 A significant reduction in withdrawal latencies was obtained for CORT pretreated rats compared to animals given only nicotine. CORT drug nicotine 7870994 Results also suggest that a conditioned release of endogenous CORT was triggered by stimuli associated with nicotine delivery. CORT drug nicotine 7870994 These data are consistent with the hypothesis that a conditioned release of CORT could contribute to the development of tolerance to some of nicotine's effects. EGFR drug opioid 32111605 EGFR signaling causes morphine tolerance and mechanical sensitization in rats. EGFR addiction sensitization 32111605 EGFR signaling causes morphine tolerance and mechanical sensitization in rats. EGFR drug opioid 32111605 It has been shown that the platelet derived growth factor receptor beta (PDGFR ↓), an RTK that has been shown to interact with the EGFR, mediates opioid tolerance but does not induce analgesia. EGFR drug opioid 32111605 Therefore, we sought to determine whether EGFR signaling was involved in opioid tolerance and if EGFR and PDGFR signaling could induce pain in rats.We found that gefitinib, an EGFR antagonist, eliminated morphine tolerance. EGFR addiction sensitization 32111605 EGFR and PDGFR ↓ signaling interacted to produce this sensitization. EGFR drug opioid 32111605 EGFR was widely expressed in primary sensory afferent cell bodies, demonstrating a neuroanatomical substrate for our findings.Taken together, our results suggest a direct mechanistic link between opioid tolerance and mechanical sensitization. EGFR addiction sensitization 32111605 EGFR was widely expressed in primary sensory afferent cell bodies, demonstrating a neuroanatomical substrate for our findings.Taken together, our results suggest a direct mechanistic link between opioid tolerance and mechanical sensitization. EGFR drug opioid 32111605 EGFR antagonism could eventually play an important clinical role in the treatment of opioid tolerance and neuropathic pain that is refractory to opioid treatment.SIGNIFICANCE STATEMENT Opioid tolerance and associated reduced effectiveness of opioids against neuropathic pain are two major clinical problems that are prime contributors to the opioid epidemic. EGFR drug opioid 32111605 Here we show that EGFR antagonism not only blocks morphine tolerance but also restores the effectiveness of opioids against neuropathic pain. EGFR drug opioid 32111605 EGFR antagonism could eventually play an important role in the treatment of opioid tolerance and severe neuropathic pain that requires ever increasing doses of opioids. EGFR drug alcohol 31883696 There was a significant interaction between alcohol consumption and eGFR for CKD progression. EGFR addiction intoxication 31883696 The slopes of eGFR decline were steeper in binge drinkers among patients with eGFR less than 60 mL/min/1.73 m2. EGFR drug nicotine 31710020 The clinicopathological data included age, gender, smoking history, tumor staging, lymph node staging, surgical methods, subtypes, thyroid transcription factor 1 (TTF 1) expression, EGFR gene mutation and follow up records were investigated. EGFR drug alcohol 31617071 Evidence has emerged that 5 RTKs (tropomyosin related kinase B (TrkB), RET proto oncogene (RET), anaplastic lymphoma kinase (ALK), fibroblast growth factor receptor (FGFR), and epidermal growth factor receptor (EGFR)) modulate alcohol drinking and other behaviors related to alcohol addiction.

EGFR drug alcohol 31617071 This review will examine the preclinical evidence describing TrkB, RET, ALK, FGFR, and EGFR modulation of alcohol drinking and other behaviors relevant to alcohol abuse. EGFR drug nicotine 31393548 Forty eight patients (55%) were never smokers, 45 patients (51%) were of Eastern Cooperative Oncology Group performance status 1, and 59 patients (67%) had EGFR exon 19 deletion. EGFR addiction relapse 31230189 The renal end point (doubling of serum creatinine or ESRD) occurred in 8% of the patients; however, eGFR in patients with relapse was similar to that of non recurrent at the diagnoses, but it decreased over time more in the relapsing than in non relapsing patients (p group = 0.20; p time = 0.001; p time × group interactions = 0.04). EGFR drug nicotine 31125062 In certain subgroups, PFS was positively associated with PD L1 expression (KRAS, EGFR) and with smoking status (BRAF, HER2). EGFR drug nicotine 30598264 We demonstrated the correlation between nicotine and epidermal growth factor receptor (EGFR) signaling. EGFR drug nicotine 30598264 We demonstrated the correlation between nicotine and epidermal growth factor receptor (EGFR) signaling. EGFR drug nicotine 30598264 Nicotine treatment induced HSC 2 cell proliferation and migration and the phosphorylation of EGFR. EGFR drug nicotine 30598264 Furthermore, nicotine treatment activated the EGFR downstream effectors phosphatidylinositol 3 kinase/AKT and p44/42 mitogen activated protein kinases (ERK), which, in turn, promoted cell proliferation. EGFR addiction addiction 30449623 Cetuximab, an epidermal growth factor receptor inhibitor, has been proposed for treatment de escalation in this setting to reduce the toxicity of standard cisplatin treatment, but no randomised evidence exists for the efficacy of this strategy. EGFR drug nicotine 30431077 To the best of our knowledge, the present study is the first to demonstrate the role of nicotine in metastasis and anti‑EGFR‑therapy resistance of HNSCC. EGFR drug nicotine 30431077 The present findings demonstrated that nicotine increased proliferation, migration, invasion, p‑EGFR nuclear translocation and protein kinase B (Akt) phosphorylation in HNSCC cells. EGFR drug nicotine 30431077 Finally, an in vivo experiment revealed that nicotine increased lymph node metastasis of xenografted tumors, whereas an nAChR inhibitor suppressed lymph node metastasis and p‑EGFR nuclear localization of xenografted tumors. EGFR drug nicotine 30431077 Taken together, these results demonstrated that nicotine induced nuclear accumulation of p‑EGFR, and activation of Akt signaling. EGFR addiction relapse 30230541 During follow up, one female patient with EGFR exon 19 deletion and NF1 Q1815X comutation showed poor response to EGFR TKIs (Gefitinib and Osimertinib) after disease relapse. EGFR addiction aversion 30038519 No significant difference was found between CTA expression and epidermal growth factor receptor mutant status. EGFR drug alcohol 29774782 The Neuroprotective Effect of Ethanol Intoxication in Traumatic Brain Injury Is Associated with the Suppression of ErbB Signaling in Parvalbumin Positive Interneurons. EGFR addiction intoxication 29774782 The Neuroprotective Effect of Ethanol Intoxication in Traumatic Brain Injury Is Associated with the Suppression of ErbB Signaling in Parvalbumin Positive Interneurons. EGFR drug alcohol 29774782 Administration of selective ErbB inhibitors was able to recapitulate, to a significant extent, the neuroprotective effects of ethanol both in sensorimotor performance and structural integrity. EGFR addiction addiction 29570930 Cigarette smoke enhances oncogene addiction to c MET and desensitizes EGFR expressing non small cell lung cancer to EGFR TKIs. EGFR drug nicotine 29570930 Cigarette smoking is one of the leading risks for lung cancer and is associated with the insensitivity of non small cell lung cancer (NSCLC) to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs). EGFR drug nicotine 29570930 Cigarette smoking is one of the leading risks for lung cancer and is associated with the insensitivity of non small cell lung cancer (NSCLC) to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs). EGFR drug nicotine 29570930 In this study, our data showed that chronic exposure to cigarette smoke extract (CSE) or tobacco smoke derived carcinogen benzo[α]pyrene, B[α]P, but not nicotine derived nitrosamine ketone (NNK), reduced the sensitivity of wild type EGFR expressing NSCLC cells to EGFR TKIs. EGFR drug nicotine 29471517 The gender, tumour differentiation, epidermal growth factor receptor mutation, smoking habits, lymphovascular space invasion, tumour size, maximum standard uptake value and carcinoembryonic antigen levels were significantly different in the 2 groups. EGFR drug opioid 29216892 Opioid agonist therapy has been widely used to reduce harms among individuals with opioid use disorder but its effectiveness has not been evaluated in the Middle East North African (MENA) region. EGFR drug opioid 29216892 Results support expanding the access to opioid agonist therapy in other MENA countries to treat substance dependence and reduce harms among individuals with opioid use disorder. EGFR addiction dependence 29216892 Results support expanding the access to opioid agonist therapy in other MENA countries to treat substance dependence and reduce harms among individuals with opioid use disorder. EGFR drug nicotine 29186353 EGFR mutations were found predominantly in never smokers; KRAS in current/former smokers. EGFR drug nicotine 28974261 Why are mutation rates in epidermal growth factor receptor (EGFR) and erb b2 receptor tyrosine kinase 2 (ERBB2) higher in lung cancer from never smokers than that from smokers?

EGFR addiction reward 28284947 Behavioral characterization of blocking the ErbB signaling during adolescent and adulthood in reward liking (preference) and reward related learning. EGFR drug alcohol 28284947 In the current study, we extend our findings and explore whether inhibition of the ErbB pathway during adolescence or adulthood also affects alcohol preference (hedonic "liking"), avoidance learning, and motivational reward "wanting". EGFR addiction reward 28284947 In the current study, we extend our findings and explore whether inhibition of the ErbB pathway during adolescence or adulthood also affects alcohol preference (hedonic "liking"), avoidance learning, and motivational reward "wanting". EGFR drug alcohol 28284947 We demonstrated that chronic administration of the pan ErbB kinase inhibitor JNJ28871063 (JNJ) to adolescent mice, but not to adult mice, reduced alcohol preference compared with the saline injected group, without affecting avoidance learning as measured by increasing concentrations of quinine in the bitter avoidance test. EGFR addiction reward 28284947 These data support our initial findings that interruption of the ErbB pathway during adolescence emerges in a reduced hedonic capacity that persists into adulthood, without disturbing avoidance and reward learning. EGFR addiction reward 28284947 In addition, this paper provides a further behavioral role of the ErbB signaling pathway in the reward system, and suggests a different time period for the involvement of the pathway in the "liking" and the "wanting" components of the system. EGFR drug nicotine 27843633 Smoking habits, histological subtype, and epidermal growth factor receptor mutation status were not associated with PD L1 expression score. EGFR drug alcohol 26700849 For example, we demonstrate that MEK inhibitors amplify the viability effect of the clinically used anti alcoholism drug disulfiram and show that the EGFR inhibitor tyrphostin AG555 has off target activity on the proteasome. EGFR drug amphetamine 26322025 Similarly, compared to only infected mice, epidermal growth factor receptor (EGFR) in METH exposed LCMV infected mice were up regulated. EGFR drug amphetamine 26322025 Similarly, compared to only infected mice, epidermal growth factor receptor (EGFR) in METH exposed LCMV infected mice were up regulated. EGFR drug nicotine 26246248 "Impact of Smoking Cessation Treatment" on Lung Function and Response Rate in EGFR Mutated Patients: A Short Term Cohort Study. EGFR drug nicotine 26246248 A group of ten current smokers affected by NSCLC with EGFR activating mutation and concurrent mild COPD undergoing anti EGFR treatment without smoking cessation was used to compare clinical and functional data. EGFR drug nicotine 26246248 The combination of anti EGFR treatment and concurrent therapy for smoking cessation seems to be more effective than erlotinib alone in improving lung function and clinical response in advanced NSCLC patients with EGFR mutations. EGFR drug nicotine 26026961 Here, we hypothesized that nickel accumulation in lung tissues could contribute to EGFR mutations in never smokers with lung cancer. EGFR drug nicotine 25456362 In this open label, multicentre, phase 2 trial, we enrolled treatment naive patients with advanced lung cancer who had clinical (never smokers [<100 cigarettes per lifetime] or former light smokers [<10 pack years per lifetime] and ≥15 years since last cigarette) or molecular (EGFR mutation, regardless of smoking status) characteristics associated with response to EGFR inhibitors. EGFR drug nicotine 25442336 In addition to the well known characteristics of patients carrying EGFR mutations (female, adenocarcinoma, and never/light smoker), the proportion of cases with smaller primary lesions (T1/2) was found to be higher in patients with EGFR mutations than in those with wild type EGFR. EGFR addiction relapse 25442336 Patients with EGFR mutations showed similar response rate, relapse free survival, and 2 year relapse free rates as compared to patients with wild type EGFR. EGFR addiction relapse 25442336 Local relapses as the site of initial relapse occurred significantly less frequently in patients with EGFR mutation (4% vs 21%; P=.045). EGFR drug nicotine 25152623 Smoking, a solid predominant pattern, and a mucinous component were independently associated with fewer EGFR mutations. EGFR drug alcohol 24923262 Compared with abstinence, the odds ratio for a decrease in estimated glomerular filtration rate (eGFR) was 0.14 (95% CI: 0.01 0.91) among heavy drinkers, and 0.42 (95% CI: 0.17 0.98) among binge drinkers and the association between the amount of mean daily alcohol intake, binge drinking status and a likelihood of reduced eGFR value showed significant trends (p = 0.041 and p = 0.038, respectively), after adjusting for age, smoking status, amount of physical activity, morbid hypertension, diabetes, dyslipidaemia, anaemia and body mass index. EGFR drug nicotine 24923262 Compared with abstinence, the odds ratio for a decrease in estimated glomerular filtration rate (eGFR) was 0.14 (95% CI: 0.01 0.91) among heavy drinkers, and 0.42 (95% CI: 0.17 0.98) among binge drinkers and the association between the amount of mean daily alcohol intake, binge drinking status and a likelihood of reduced eGFR value showed significant trends (p = 0.041 and p = 0.038, respectively), after adjusting for age, smoking status, amount of physical activity, morbid hypertension, diabetes, dyslipidaemia, anaemia and body mass index. EGFR addiction intoxication 24923262 Compared with abstinence, the odds ratio for a decrease in estimated glomerular filtration rate (eGFR) was 0.14 (95% CI: 0.01 0.91) among heavy drinkers, and 0.42 (95% CI: 0.17 0.98) among binge drinkers and the association between the amount of mean daily alcohol intake, binge drinking status and a likelihood of reduced eGFR value showed significant trends (p = 0.041 and p = 0.038, respectively), after adjusting for age, smoking status, amount of physical activity, morbid hypertension, diabetes, dyslipidaemia, anaemia and body mass index. EGFR drug alcohol 24923262 Alcohol consumption was inversely associated with a reduction in eGFR in Korean men. EGFR drug alcohol 24710718 We hypothesized that Cav 1 could attenuate ethanol mediated nitrosative stress and liver damage through regulating epidermal growth factor receptor/signal transducer and activator of transcription 3/inducible nitric oxide synthase (EGFR/STAT3/iNOS) signaling cascades. EGFR drug alcohol 24710718 We hypothesized that Cav 1 could attenuate ethanol mediated nitrosative stress and liver damage through regulating epidermal growth factor receptor/signal transducer and activator of transcription 3/inducible nitric oxide synthase (EGFR/STAT3/iNOS) signaling cascades. EGFR drug alcohol 24710718 Furthermore, the results revealed that the ethanol mediated Cav 1 increase was in an extracellular signal regulated kinase dependent manner, and Cav 1 protected hepatocytes from ethanol mediated apoptosis by inhibiting iNOS activity and regulating EGFR and STAT3 signaling cascades. EGFR drug alcohol 24710718 Cav 1 could be a cellular defense protein against alcoholic hepatic injury through inhibiting reactive nitrogen species and regulating EGFR/STAT3/iNOS signaling cascades. EGFR drug opioid 24304333 In prior studies, we discovered that the mechanism of TSP1 regulation by μ opioids in astrocytes involves crosstalk between three different classes of receptors, μ opioid receptor, EGFR and TGFβR. EGFR drug opioid 24304333 Moreover, TGFβ1 stimulated TSP1 expression via EGFR and ERK/MAPK activation, indicating that EGFR is a signaling hub for opioid and TGFβ1 actions. EGFR addiction relapse 23775406 ANCCA expression was evaluated by immunohistochemistry in 143 surgically resected lung adenocarcinomas and was correlated with clinicopathologic and molecular variables including adenocarcinoma histologic subtypes, tumor, node, metastasis status, relapse free survival, overall survival, EGFR mutations, KRAS mutations, HER2 mutations and ALK fusions.

EGFR drug nicotine 23150706 Patients with lung adenocarcinomas with RET fusion gene had more poorly differentiated tumors (63.6%; P = .029 for RET v ALK, P = .007 for RET v EGFR), with a tendency to be younger (≤ 60 years; 72.7%) and never smokers (81.8%) and to have solid subtype (63.6%) and a smaller tumor (≤ 3 cm) with N2 disease (54.4%). EGFR drug opioid 23142605 EGFR dependent subcellular communication was responsible for morphine mediated AC superactivation. EGFR drug opioid 23142605 In the present study, we demonstrated that chronic morphine treatment sensitized EGFR signaling by augmenting EGFR phosphorylation and translocation into ER, which was essential for CRT MOR tethering within the lipid rafts and AC5 superactivation. EGFR drug opioid 23142605 Taken together, our data raised the possibility that an adaptive change in MOR and EGFR signal systems might establish CRT related subcellular communication, the signaling network within brain synaptic zone was proposed to implicate in morphine tolerance and dependence.

EGFR drug nicotine 21655907 In addition, most adenocarcinomas in never smokers harbor one of the proto oncogene aberrations that occur in a mutually exclusive manner (EGFR mutation, KRAS mutation, HER2 mutations, or ALK translocation). EGFR addiction relapse 21247966 EGFR gene copy number gain is related to high tumor SUV and frequent relapse after adjuvant chemotherapy in resected lung adenocarcinoma. EGFR drug nicotine 21247966 EGFR copy number change did not correlate with age, gender or smoking history. EGFR addiction relapse 21247966 EGFR copy number gain is associated with aggressive tumor biology and is a poor prognostic factor for tumor relapse in resected lung adenocarcinoma patients receiving adjuvant chemotherapy of paclitaxel and carboplatin. EGFR drug nicotine 21178720 The nine selected studies covered a broad range of topics including possible hormonal role in the development of lung adenocarcinoma, lung cancer in never smokers, stereotactic radiotherapy for early stage lung cancer, prognostic role of pleural lavage cytology, neoadjuvant chemotherapy for operable lung cancer, maintenance erlotinib, use of erlotinib after gefitinib, comparison of the two epidermal growth factor receptor tyrosine kinase inhibitors, and risk of central nervous system relapse in patients treated with epidermal growth factor receptor tyrosine kinase inhibitors.

EGFR drug nicotine 18262213 Moreover, addition of AG1478, an inhibitor of EGFR tyrosine phosphorylation, or cetuximab, a monoclonal antibody that precludes ligand binding to the same receptor, prevented cell differentiation by nicotine. EGFR drug nicotine 17932690 Smoking status (never smoker vs. smoker, P=0.0032), and pathological subtypes (adenocarcinoma vs. non adenocarcinoma, P=0.0011), but not EGFR amplification (P=0.1278), were correlated with survival of lung cancers. EGFR drug nicotine 17649787 The initial positive effect of combination chemotherapy with erlotinib as the first line of treatment correlates with several positive predictors including the type of carcinoma, non smoking status, occurrence of rash and the presence of exon 19 EGFR gene mutation.

PTGS2 drug amphetamine 31228610 Intervention with a selective COX 2 inhibitor during EtOH drinking prevented the changes in microglia, and attenuated the increase in cleaved caspase 3, and decreases in TH and DAT after Meth administration. PTGS2 drug cannabinoid 30796025 In addition to arachidonic acid, COX 2 oxidizes the endocannabinoid 2 arachidonoylglycerol (2 AG) to produce prostaglandin E2 (PGE2) glycerol (PGE2 G); PGE2 G is known to produce hyperalgesia.

PTGS2 drug cannabinoid 30618769 In addition to the well characterized hydrolytic pathways, cyclooxygenase 2 (COX 2) mediated oxygenation is thought to be an alternative route for endocannabinoid metabolism and therefore provides a new avenue for drug intervention. PTGS2 drug opioid 30388619 Astrocyte EV Induced lincRNA Cox2 Regulates Microglial Phagocytosis: Implications for Morphine Mediated Neurodegeneration. PTGS2 drug opioid 30388619 Herein, we show that EVs derived from astrocytes exposed to morphine can be taken up by microglial endosomes, leading, in turn, to activation of Toll like receptor 7 (TLR7) with a subsequent upregulation of lincRNA Cox2 expression, ultimately resulting in impaired microglial phagocytosis. PTGS2 drug opioid 30388619 Additionally, we also showed that intranasal delivery of EVs containing lincRNA Cox2 siRNA (small interfering RNA) was able to restore microglial phagocytic activity in mice administered morphine. PTGS2 drug amphetamine 30002494 Exposure to CUS prior to unrestricted Meth self administration had no effect on Meth intake in rats; however, the pro inflammatory mediator cyclooxygenase 2 (COX 2) and the breakdown of cell matrix adhesion protein β dystroglycan in isolated cerebral cortical capillaries were increased after 3 days of abstinence and persisted for 7 days. PTGS2 drug amphetamine 30002494 The decrease in occludin was blocked by the COX 2 specific inhibitor nimesulide treatment during abstinence from Meth. PTGS2 drug amphetamine 30002494 The changes in COX 2, β dystroglycan, and occludin were only evident following the serial exposure to stress and Meth but not after either one alone. PTGS2 drug amphetamine 30002494 Furthermore, COX 2 inhibition may be a viable pharmacological intervention to block vascular changes after Meth exposure. PTGS2 drug opioid 29992509 Chronic pain after osteoporotic fractures requires a multifaceted approach, which includes a large spectrum of drugs (antiosteoporosis treatment, acetaminophen, NSAIDs, selective COX 2 inhibitors, weak and strong opioids) and non pharmacological treatment. PTGS2 drug amphetamine 29944913 In the present study, we observed that the toxic high dose of METH treated neuroblastoma SH SY5Y cells significantly decreased cell viability but increased apoptotic cell death, the active cleaved form of calcineurin, the nuclear translocation of NFAT, and COX 2 levels. PTGS2 drug amphetamine 29944913 These findings might emphasize the role of calpastatin against METH induced toxicity by a mechanism related to calpain dependent CaN NFAT activation induced COX 2 expression.

PTGS2 drug opioid 29576123 Accumulated evidence suggests that spinal cyclooxygenase 2 (COX 2) and prostaglandin E2 (PGE2) may be implicated in the development of opioid induced hyperalgesia. PTGS2 drug opioid 29576123 This behavioural change was paralleled with an increase in spinal COX 2 mRNA and PGE2 after fentanyl administration. PTGS2 drug psychedelics 29404791 Regional analgesia and agents such as ketamine, gabapentinoids, and COX 2 inhibitors have also been found to decrease the risks of developing chronic pain to varying degrees. PTGS2 drug cannabinoid 29364174 Following MIA administration, we observed 2 4 fold increase in mRNA expression of targeted receptors (Cnr1, Cnr2, and Trpv1), endocannabinoid degradation enzymes (Faah, Ptgs2, and Alox12), and TRPV1 sensitizing kinases (Mapk3, Mapk14, Prkcg, and Prkaca). PTGS2 drug amphetamine 28856500 Cyclooxygenase inhibition by ketoprofen during EtOH drinking blocked the increases in LPS and COX 2 and the enhanced decreases in dopamine and serotonin produced by Meth. PTGS2 drug alcohol 28408342 These data were supported by functional evidence since chronic alcohol consumption produced no changes in the expression of TNF α or COX 2. PTGS2 addiction sensitization 28126501 The prevention of this hyperalgesia by diclofenac (1 10μg), the inhibitors of COX 1 SC 560 (0.1 1μg) or COX 2 celecoxib (1 5μg), the TRPV1 antagonist capsazepine (0.03 0.3μg) or the TRPA1 antagonist HC030031 (10 50μg) demonstrates the involvement of prostaglandin synthesis and TRP sensitization in CCL5 evoked hyperalgesia. PTGS2 drug cannabinoid 27470501 In 7 days pregnant wild type, but not cannabinoid receptor type 1 knockout (CB1 KO) mice, LPS increased COX 2 expression and prostaglandin F2α (PGF2α) production in the uterus leading to lower expression of prolactin receptor in the ovary and a marked regression of corpora lutea (CL), suggesting that the eCS mediates the deleterious effects of LPS on reproductive events. PTGS2 addiction withdrawal 27470501 Treatment of 7 day pregnant WT mice with LPS induced a P4 withdrawal (p < 0.05), increased in uterine COX 2 mRNA and protein expression (p < 0.05) as well as an increase in uterine PGF2α production (p < 0.05).

PTGS2 drug alcohol 26857094 OEA reduced the levels of interleukin 1beta (IL 1β), the monocyte chemoattractant protein 1 (MCP 1), and the enzymes cyclooxygenase 2 (COX 2) and inducible nitric oxide synthase (iNOS) in ethanol binged animals. PTGS2 drug opioid 26803746 Multimodal analgesia that includes prophylactic administration of selective cyclooxygenase 2 (COX 2) inhibitors can improve postoperative pain and reduce opioid analgesic consumption after total knee arthroplasty (TKA). PTGS2 drug cannabinoid 25712641 The results of this study seemed to indicate that the interaction between cannabinoid, COX 2 and NOS(s) systems might exist. PTGS2 drug alcohol 25486089 Using wild type (WT) and TLR4 deficient (TLR4 KO) adolescent mice treated intermittently with ethanol (3.0g/kg) for 2weeks, we show that binge like ethanol treatment activates TLR4 signaling pathways (MAPK, NFκB) leading to the up regulation of cytokines and pro inflammatory mediators (COX 2, iNOS, HMGB1), impairing synaptic and myelin protein levels and causing ultrastructural alterations.

PTGS2 drug opioid 24284847 cyclo oxygenase 2 (COX 2) nonsteroidal anti inflammatory drugs (NSAIDs), tramadol, and opioids were commonly used. PTGS2 drug cannabinoid 24008428 We evaluated the pharmacology of spinal selective cannabinoid (CB) receptor agonists and a cyclooxygenase 2 (COX 2) inhibitor on bone tumor pain. PTGS2 addiction withdrawal 24008428 Intrathecal CB1 (ACEA) and CB2 receptor (AM 1241) agonists and a COX 2 inhibitor (DuP 697) dose dependently increased the withdrawal threshold. PTGS2 drug opioid 23243929 Equally dangerous can be an abuse of tramadol, codeine and COX 2 inhibitors. PTGS2 drug opioid 22845665 Induction of P glycoprotein and Bcrp at the rat blood brain barrier following a subchronic morphine treatment is mediated through NMDA/COX 2 activation. PTGS2 drug alcohol 22749946 Chronic self administration of ethanol reduced the expression of the C fos gene 4 to 12 fold and increased expression of the COX 2 (up to 4 fold) and Homer1a genes in the rat prefrontal cortex. PTGS2 drug cannabinoid 22363560 It was suggested that endocannabinoids are metabolized by cyclooxygenase (COX) 2 in the spinal cord of rats with kaolin/λ carrageenan induced knee inflammation, and that this mechanism contributes to the analgesic effects of COX 2 inhibitors in this experimental model. PTGS2 drug cannabinoid 22363560 We report the development of a specific method for the identification of endocannabinoid COX 2 metabolites, its application to measure the levels of these compounds in tissues, and the finding of prostamide F(2α) (PMF(2α)) in mice with knee inflammation. PTGS2 drug cannabinoid 22363560 Whereas the levels of spinal endocannabinoids were not significantly altered by kaolin/λ carrageenan induced knee inflammation, those of the COX 2 metabolite of AEA, PMF(2α), were strongly elevated. PTGS2 drug nicotine 21210228 Furthermore, COX 2 signal was induced by nicotine treatment and is involved in nicotine enhanced fibronectin expression. PTGS2 drug opioid 20967889 In this article, the phase 1 and 2 metabolisms of seven of the most important classes of drugs monitored in horseracing are reviewed, including: anabolic androgenic steroids (AAS), β₂ agonists, stimulants, sedatives/tranquilizers, local anesthetics, non steroidal anti inflammatory analgesics (NSAIDS)/cyclooxygenase 2 (COX 2) inhibitors, and opioid analgesics. PTGS2 drug opioid 20346263 To determine which class of non opioid analgesics paracetamol (acetaminophen), NSAIDs or COX 2 inhibitors is the most effective at reducing morphine consumption and associated adverse effects when used as part of multimodal analgesia following major surgery. PTGS2 drug opioid 20346263 Randomised controlled trials comparing paracetamol, NSAIDs or COX 2 inhibitors to each other or placebo, in adults receiving patient controlled analgesia (PCA) with morphine following major surgery, were included. PTGS2 drug opioid 20346263 When paracetamol, NSAIDs or COX 2 inhibitors were added to PCA morphine, there was a statistically significant reduction in morphine consumption: paracetamol (MD 6.34 mg; 95% CrI 9.02 to 3.65); NSAIDs (MD 10.18; 95% CrI 11.65 to 8.72); and COX 2 inhibitors (MD 10.92; 95% CrI 12.77 to 9.08). PTGS2 drug opioid 20346263 24 hour morphine consumption decreased by 6.3 mg to 10.9 mg, compared to placebo, when paracetamol, NSAID or COX 2 inhibitors were added to PCA morphine following surgery. PTGS2 drug cannabinoid 19879047 Recently, however, COX 2 was shown to be also involved in the metabolism of endocannabinoids. PTGS2 drug cannabinoid 19879047 The reversal of spinal hyperexcitability by COX 2 inhibitors was prevented or partially reversed by AM 251, an antagonist at the cannabinoid 1 receptor. PTGS2 drug cannabinoid 19879047 We conclude that inhibition of spinal COX 2 not only reduces PG production but also endocannabinoid breakdown and provide evidence that reversal of inflammation evoked spinal hyperexcitability by COX 2 inhibitors is more related to endocannabinoidergic mechanisms than to inhibition of spinal PG synthesis. PTGS2 drug nicotine 18805435 Treatment of cells with alpha bungarotoxin (alpha BTX, alpha7nAChR antagonist) or propranolol (beta adrenergic receptor antagonist) blocked NNK induced COX 2/PGE(2) and cell proliferation, while nicotine mediated cell growth and COX 2/PGE(2) induction can only be suppressed by propranolol, but not alpha BTX. PTGS2 drug nicotine 18805435 Moreover, in contrast to the dependence of growth promoting effect of nicotine on Erk activation, inhibitor of p38 mitogen activated protein kinase (MAPK) repressed NNK induced COX 2 upregulation and resulted in suppression of cell growth.

PTGS2 drug alcohol 17284196 Administration of indomethacin, a COX 2 inhibitor, abolishes the induction of COX 2 and iNOS expression and cell death, preventing ethanol induced behavioural deficits. PTGS2 drug alcohol 17127267 Recent findings indicate that low concentrations of ethanol (10 mM) promote inflammatory processes in brain and in glial cells by up regulating cytokines and inflammatory mediators (iNOS, NO, COX 2), and by activating signaling pathways (IKK, MAPKs) and transcriptional factors (NF kappaB, AP 1) implicated in inflammatory injury.

PTGS2 drug opioid 16741783 These guidelines, formulated in response to recent developments concerning COX 2 inhibitors and other NSAIDs, focus on paracetamol as the baseline drug for chronic pain management; when greater analgesia is desired, the addition of weak opioids is recommended based on a preferable GI and cardiovascular profile, compared with non steroidal anti inflammatory drugs.

PTGS2 addiction sensitization 15985101 To determine whether delayed infusion of COX1/COX2 inhibitors (ketorolac, indomethacin) will stop migraine in allodynic patients, and suppress ongoing sensitization in central trigeminovascular neurons in the rat. PTGS2 addiction sensitization 15985101 The induction of sensitization (using topical application of inflammatory soup on the dura) and its suppression by COX1/COX2 inhibitors were assessed by monitoring changes in spontaneous activity and responses to mechanical and thermal stimuli.

PTGS2 drug nicotine 12941074 Currently, there is limited information on the regulation of COX 2 expression in smoking associated periodontal disease. PTGS2 drug nicotine 12941074 The aim of the present study was to investigate the effects of nicotine on the expression of cyclooxygenase 2 (COX 2) mRNA gene and protein in cultured human gingival fibroblasts (HGFs). PTGS2 drug nicotine 12941074 Furthermore, to elucidate whether induction of COX 2 may be associated with nicotine induced cytotoxicity, NS 398 (a selective COX 2 inhibitor), was added to test its protective effect. PTGS2 drug nicotine 12941074 The exposure of quiescent human HGFs to nicotine resulted in the induction of COX 2 mRNA expression. PTGS2 drug nicotine 12941074 The levels of the COX 2 mRNAs increased about 1.5 and 2.5 fold after exposure to 2.5 and 15 mm nicotine for 2 h (P < 0.05), respectively. PTGS2 drug nicotine 12941074 Moreover, the peak of COX 2 mRNA levels induced by nicotine was 10 mm at 2 h incubation period. PTGS2 drug nicotine 12941074 Investigations of the time dependence of COX 2 mRNA expression in nicotine treated HGFs revealed a rapid accumulation of the transcript, a signal first detectable at 30 min and diminished to control level after 8 h. In addition, 10 mm nicotine also induced COX 2 protein expression in HGFs. PTGS2 addiction dependence 12941074 Investigations of the time dependence of COX 2 mRNA expression in nicotine treated HGFs revealed a rapid accumulation of the transcript, a signal first detectable at 30 min and diminished to control level after 8 h. In addition, 10 mm nicotine also induced COX 2 protein expression in HGFs. PTGS2 drug nicotine 12941074 The kinetics of this response showed that COX 2 was detectable at 4 h and diminished nearly to control level after 24 h. NS 398 at non cytotoxic dose is not able to prevent nicotine induced cytotoxicity. PTGS2 drug nicotine 12941074 Taken together, the activation of COX 2 expression by nicotine suggests a potential role for nicotine in the pathogenesis of smoking associated periodontal disease. PTGS2 drug nicotine 12941074 In addition, nicotine induced cytotoxicity is not directly via the induction of COX 2 expression. PTGS2 drug psychedelics 12522725 It consists of the simultaneous administration of low dose ketamine, co administration of an alpha 2 agonist, and the administration of a selective COX 2 inhibitor (refecoxib, parecoxib) respectively.

PTGS2 drug opioid 12086297 Clinical studies show that COX 2 selective inhibitors are effective for the treatment of preoperative and postoperative pain and reduce postsurgical requirements for opioids. PTGS2 addiction sensitization 12086297 This evidence supports a role for COX 2 derived prostaglandins as key mediators of nociceptive pain and peripheral sensitization (hyperalgesia).

BCL2 drug amphetamine 32203791 We further examined ER stress related proteins and mitochondrial apoptosis pathway in the VTA and NAc, and found that METH increased the expressions of glucose regulated protein 78 (GRP78), C/EBP homologous protein (CHOP), and Bax, as same time decreased the expressions of procaspase12, Bcl 2, and procaspase3, while Trx 1 overexpression blocked these changes. BCL2 drug amphetamine 32120831 Moreover, diminished expression of anti apoptotic proteins, including Bcl 2, Caspase3, Caspase7, and Caspase8 in METH exposed SH SY5y cells, was significantly recovered by treatment with lupenone.

BCL2 drug opioid 27544013 The results showed that the expression of Bcl 2 was very weak and those of Bax and Caspase 3 were hardly seen in group normal saline; the expressions of Bax and Caspase 3 were strong and that of Bcl 2 was weak in group morphine and compared to group normal saline, there were significant differences (P<0.05); the expressions of Bax, Caspase 3 and the ratios of Bax/Bcl 2 have a gradually decreased trend in the sequence of group 0.01μg, group 0.1μg and group 1.0μg, but the expression of Bcl 2 has an opposite trend in the same sequence, and compared to group morphine, there were significant differences (P<0.05) excluding group 0.01μg. BCL2 drug opioid 27544013 So we draw a conclusion that CCK 8 (0.1 and 1.0μg, i.c.v) could protect neurons of prefrontal cortex through up regulating the expression of Bcl 2, down regulating those of Bax and Caspase 3 and reducing Bax/Bcl 2 ratio in the model of morphine relapse rats.

IGBP1 addiction dependence 17712039 Nicotinic receptors containing the alpha 4 subunit (alpha 4* nAChRs) have high sensitivity and are widely expressed in the central nervous system, yet their contributions to behavioral tolerance, a hallmark of nicotine dependence, are unclear. IGBP1 drug nicotine 17712039 To evaluate the contribution of alpha 4* and non alpha 4 nAChRs in the development of tolerance to hypothermia and locomotor suppression, alpha 4 knockout (KO), hypersensitive Leu9'Ala alpha 4 knock in, and wild type (WT) mice received daily nicotine injections, and their behaviors were compared. IGBP1 drug nicotine 17712039 In addition, daily selective activation of alpha 4* nAChRs elicited locomotor activation in Leu9'Ala mice, but nicotine suppressed activity in alpha 4 KO mice and this did not change with daily drug exposure. IGBP1 drug nicotine 17670967 Chronic nicotine cell specifically upregulates functional alpha 4* nicotinic receptors: basis for both tolerance in midbrain and enhanced long term potentiation in perforant path. IGBP1 drug nicotine 17584502 These results indicate that beta2 containing nAChRs, such as the alpha 4 beta 2 receptor, mediate nicotine withdrawal deficits in contextual fear conditioning.

IGBP1 drug nicotine 16894067 Cigarette smoking saturates brain alpha 4 beta 2 nicotinic acetylcholine receptors. IGBP1 drug nicotine 16894067 To determine the effect of cigarette smoking on alpha 4 beta 2* nAChR occupancy in tobacco dependent smokers. IGBP1 drug nicotine 16894067 Main Outcome Measure Dose dependent effect of smoking on occupancy of alpha 4 beta 2* nAChRs, as measured with 2 FA and PET in nAChR rich brain regions. IGBP1 drug nicotine 16894067 Smoking 0.13 (1 to 2 puffs) of a cigarette resulted in 50% occupancy of alpha 4 beta 2* nAChRs for 3.1 hours after smoking. IGBP1 drug nicotine 16894067 A venous plasma nicotine concentration of 0.87 ng/mL (roughly 1/25th of the level achieved in typical daily smokers) was associated with 50% occupancy of alpha 4 beta 2* nAChRs. IGBP1 drug nicotine 16894067 Cigarette smoking in amounts used by typical daily smokers leads to nearly complete occupancy of alpha 4 beta 2* nAChRs, indicating that tobacco dependent smokers maintain alpha 4 beta 2* nAChR saturation throughout the day. IGBP1 drug nicotine 16894067 Because prolonged binding of nicotine to alpha 4 beta 2* nAChRs is associated with desensitization of these receptors, the extent of receptor occupancy found herein suggests that smoking may lead to withdrawal alleviation by maintaining nAChRs in the desensitized state.

IGBP1 drug benzodiazepine 11960630 Hormone withdrawal also produced increases in the alpha 4 containing GABAR, an effect correlated with insensitivity of the GABAR to modulation by the benzodiazepine class of tranquilizers, as would normally occur under control conditions. IGBP1 addiction withdrawal 11960630 Hormone withdrawal also produced increases in the alpha 4 containing GABAR, an effect correlated with insensitivity of the GABAR to modulation by the benzodiazepine class of tranquilizers, as would normally occur under control conditions. IGBP1 drug psychedelics 11906717 Both ibogaine and 18 methoxycoronaridine were antagonists at alpha 3 beta 4 nicotinic receptors and both agents were more potent at this site than at alpha 4 beta 2 nicotinic receptors or at NMDA or 5 HT(3) receptors; 18 methoxycoronaridine was more selective in this regard than ibogaine. IGBP1 drug nicotine 11854451 There were no changes in the levels of alpha 4, alpha 5, alpha 6, alpha 7, beta 2, and beta 4 mRNA, or in [(125)I]epibatidine and [(3)H]nicotine binding between +/T and +/+ mice. IGBP1 drug alcohol 9689472 The effects of ethanol dependence on additional GABAA receptor subunit peptide levels (alpha 4, beta 2/3 and gamma 2) were similar, but not identical, between female and male rat cortex. IGBP1 addiction dependence 9689472 The effects of ethanol dependence on additional GABAA receptor subunit peptide levels (alpha 4, beta 2/3 and gamma 2) were similar, but not identical, between female and male rat cortex. IGBP1 drug alcohol 9422812 In general, the alpha 3 beta 2, alpha 4 1 beta 2 and alpha 4 1 beta 4 subunit combinations were less sensitive to low concentrations of ethanol, but respectively showed potentiations of up to 178%, 226% and 154% at high EtOH concentrations. IGBP1 drug benzodiazepine 8913357 Pharmacological modulation of the diazepam insensitive recombinant gamma aminobutyric acidA receptors alpha 4 beta 2 gamma 2 and alpha 6 beta 2 gamma 2. IGBP1 drug benzodiazepine 8913357 We characterized modulation of the gamma aminobutyric acid (GABA) evoked responses of the diazepam insensitive alpha 4 beta 2 gamma2 and alpha 6 beta 2 gamma 2 recombinant GABAA receptors. IGBP1 addiction dependence 8913357 The partial agonist bretazenil potentiated the responses of both receptors with similar dose dependence but with a higher maximal enhancement at the alpha 4 beta 2 gamma 2 receptor. IGBP1 addiction dependence 8913357 The imidazobenzodiazepine inverse agonist Ro 15 4513, which is known to bind with high affinity to the alpha 6 beta 2 gamma 2 receptor, potentiated the GABA responses of the alpha 4 beta 2 gamma 2 and alpha 6 beta 2 gamma 2 receptor subtypes with similar dose dependence over the concentration range of 0.1 10 microM. IGBP1 drug benzodiazepine 8913357 Thus, although the alpha 4 beta 2 gamma 2 receptors are insensitive to benzodiazepine binding site full agonists, such as diazepam, they can be modulated by certain ligands acting as partial and inverse agonists at diazepam sensitive receptors and thereby contribute to the respective pharmacological profiles. IGBP1 drug alcohol 8768698 Levels for the alpha 1 and alpha 4 subunit showed only slight alteration during withdrawal whereas we had previously observed a significant decrease in alpha 1 and a significant increase in alpha 4 mRNA levels in ethanol dependent (not withdrawing) animals. IGBP1 addiction withdrawal 8768698 Levels for the alpha 1 and alpha 4 subunit showed only slight alteration during withdrawal whereas we had previously observed a significant decrease in alpha 1 and a significant increase in alpha 4 mRNA levels in ethanol dependent (not withdrawing) animals. IGBP1 drug benzodiazepine 9014161 The levels of alpha 4 and alpha , beta 1 and gamma 3 subunit mRNAs were significantly increased after 7 days of diazepam treatment, and this effect was maintained at 14 days. IGBP1 drug alcohol 7476917 We find that chronic ethanol consumption elicits a significant increase in alpha 4 subunit mRNA levels that is equal, in absolute amount, to a decrease in alpha 1 subunit mRNA levels. IGBP1 drug nicotine 7935334 Acetylcholine receptors of the same (alpha 4)2(beta 2)3 subunit composition as the predominant subtype of brain nicotinic receptors with high affinity for nicotine have been expressed in Xenopus oocytes and in a permanently transfected fibroblast cell line. IGBP1 drug nicotine 7935334 Chronic exposure of these cells to nicotine or another agonist is shown to result in an increase in receptor amount, indicating that nicotine induced up regulation reflects properties of the alpha 4 beta 2 receptor protein, rather than being an adaptive response unique to the neurons in which these receptors are normally expressed. IGBP1 drug nicotine 8192688 Although multiple subtypes of nicotine receptor are expressed in the brain, attention has focused on a prevalent subtype (containing alpha 4 and beta 2 subunits) which is believed to represent the prime target for 'smoking doses' of nicotine.

CCL2 drug cocaine 32278944 Further validation experiments showed that cocaine self administered mice had significantly increased mRNA expression of ccl2 and IL1β in the striatum but not the mPFc compared to saline controls. CCL2 drug cocaine 32278944 Consistently, we found elevated protein levels of Iba1, CCL2, TLR4 and mature IL1β in the striatum, not in the mPFc of cocaine receiving mice.

CCL2 addiction withdrawal 29499275 The 2BC drinking/withdrawal treatment had no apparent long term consequences on synaptic responses and long term potentiation (LTP) in hippocampal slices from non tg mice, whereas synaptic transmission was reduced but LTP was enhanced in hippocampal slices from CCL2 tg mice. CCL2 addiction withdrawal 29499275 In contrast, the CIE/2BC/withdrawal treatment enhanced synaptic transmission but reduced LTP in the non tg hippocampus, whereas there were no apparent long term consequences to synaptic transmission and LTP in hippocampus from CCL2 tg mice, although somatic excitability was enhanced. CCL2 drug alcohol 29499275 These results support the idea that alcohol induced CCL2 production can modulate the effects of alcohol exposure/withdrawal on synaptic function and indicate that CCL2/alcohol interactions can vary depending on the alcohol exposure/withdrawal protocol used.

CCL2 drug alcohol 28431906 Transgenic mice with increased astrocyte expression of CCL2 show altered behavioral effects of alcohol. CCL2 drug alcohol 28431906 Recently, studies have also shown that both acute and chronic alcohol consumption can produce activation of CNS glial cells and the production of neuroimmune factors, particularly the chemokine ligand 2 (CCL2). CCL2 drug alcohol 28431906 The consequences of alcohol induced increases in CCL2 levels in the CNS have yet to be fully elucidated. CCL2 drug alcohol 28431906 Our studies focus on the hypothesis that increased levels of CCL2 in the CNS produce neuroadaptive changes that modify the actions of alcohol on the CNS. CCL2 drug alcohol 28431906 Comparisons between alcohol naïve, non dependent, and alcohol dependent CCL2 transgenic and non transgenic mice show that elevated levels of CCL2 in the CNS interact with alcohol in tests for alcohol drinking, spatial learning, and associative learning.

CCL2 drug alcohol 27527870 Ethanol caused pancreatic inflammation which was indicated by the induction of TNF alpha, IL 1beta, IL 6, MCP 1 and CCR2, and the increase of CD68 positive macrophages in the pancreas. CCL2 drug alcohol 27043532 Inflammatory cytokines (interferon γ induced protein 10 (IP 10); monocyte chemoattractant protein 1 (MCP1); regulated on activation, normal T cell expressed and secreted (RANTES)) were significantly elevated in alcoholism compared to controls while bone marrow derived hematopoietic cytokines and chemokines (granulocyte colony stimulating factor (GCSF); soluble CD40 ligand (sCD40L); growth related oncogene (GRO)) were significantly reduced.

CCL2 drug amphetamine 26946780 In mice treated with methamphetamine, CCL2 mRNA was significantly increased in prefrontal cortex and nucleus accumbens. CCL2 drug amphetamine 26946780 The increment of pTH Ser40 levels in the VTA by methamphetamine was attenuated by RS504393, a selective CC chemokine receptor 2 (CCR2) antagonist, indicating that the increased CCL2 activates the brain reward system via CCR2 activation.

CCL2 drug alcohol 26857094 OEA reduced the levels of interleukin 1beta (IL 1β), the monocyte chemoattractant protein 1 (MCP 1), and the enzymes cyclooxygenase 2 (COX 2) and inducible nitric oxide synthase (iNOS) in ethanol binged animals. CCL2 drug alcohol 26683974 Among the evidence implicating neuroimmune signaling in alcohol use disorders are increased levels of the chemokine monocyte chemoattractant protein 1 (MCP 1) in the brains of human alcoholics and animal models of alcohol abuse. CCL2 drug alcohol 26683974 However, it is not known whether neuroimmune signaling can directly increase ethanol (EtOH) consumption, and whether MCP 1 is involved in that mechanism. CCL2 addiction reward 26683974 Our hypothesis was that increasing MCP 1 signaling by directly infusing it into the brain would increase operant EtOH self administration. CCL2 addiction reward 26683974 We implanted osmotic minipumps to chronically infuse either one of several doses of MCP 1 or vehicle into the cerebral ventricles (intracerebroventricular) of Long Evans rats and then tested them in the operant self administration of a sweetened EtOH solution for 8 weeks. CCL2 addiction withdrawal 26683974 MCP 1 did not influence the acquisition of self administration (measured across the first 5 days), the motivation to consume EtOH (time to lever press or progressive ratio), withdrawal induced anxiety, or the consumption of sucrose alone. CCL2 drug alcohol 26683974 Continued research into this mechanism, particularly using models of alcohol dependence, will help determine whether targeting MCP 1 signaling has therapeutic potential in the treatment of alcohol use disorders.

CCL2 addiction withdrawal 26556523 Withdrawal from Chronic Alcohol Induces a Unique CCL2 mRNA Increase in Adolescent But Not Adult Brain Relationship to Blood Alcohol Levels and Seizures. CCL2 drug alcohol 26556523 Further, a greater increase in CCL2 mRNA was observed in the cortex of adolescents at 7% CAD, which correlated with higher blood alcohol levels (BALs). CCL2 addiction withdrawal 26556523 Relative to other cytokine mRNAs, CCL2 exhibits a unique response profile during withdrawal from CAD. CCL2 drug alcohol 26365610 Building on evidence that ethanol stimulates neuroimmune factors such as the chemokine CCL2 that in adult rats is shown to colocalize with the orexigenic peptide, melanin concentrating hormone (MCH) in the lateral hypothalamus (LH), the present study sought to investigate the possibility that CCL2 or its receptor CCR2 in LH is stimulated by prenatal ethanol exposure, perhaps specifically within MCH neurons. CCL2 drug alcohol 26365610 Whereas CCL2(+) cells at this age were low in density and unaffected by ethanol, CCR2(+) cells were dense in LH and increased by prenatal ethanol, with a large percentage (83 87%) identified as neurons and found to colocalize MCH. CCL2 drug alcohol 26151816 Alcohol consumption affects the immune phenotype of CD8 cells since binge drinking pattern was found to be associated with high CD69 and low TLR4, CXCR4 and CCR2 expression, which suggest recent activation, decreased sensitivity to LPS and lower migration capacity in response to chemokines SDF 1 and MCP 1.

CCL2 drug opioid 25716997 Buprenorphine decreases the CCL2 mediated chemotactic response of monocytes. CCL2 drug opioid 25716997 Buprenorphine decreases the formation of membrane projections in response to CCL2. CCL2 drug opioid 25716997 It also decreases CCL2 induced chemotaxis and mediates a delay in reinsertion of the CCL2 receptor, CCR2, into the cell membrane after CCL2 mediated receptor internalization, suggesting a mechanism of action of buprenorphine. CCL2 drug opioid 25716997 We show that buprenorphine decreases these phosphorylations in CCL2 treated monocytes. CCL2 drug opioid 25716997 Using DAMGO, CTAP, and Nor BNI, we demonstrate that the effect of buprenorphine on CCL2 signaling is opioid receptor mediated. CCL2 drug opioid 25716997 To identify additional potential mechanisms by which buprenorphine inhibits CCL2 induced monocyte migration, we performed proteomic analyses to characterize additional proteins in monocytes whose phosphorylation after CCL2 treatment was inhibited by buprenorphine. CCL2 drug opioid 25716997 We propose that buprenorphine limits CCL2 mediated monocyte transmigration into the CNS, thereby reducing neuroinflammation characteristic of HAND. CCL2 drug alcohol 25567426 CRF amplified neuronal TLR4/MCP 1 signaling regulates alcohol self administration. CCL2 drug alcohol 25567426 We report that alcohol preferring P rats have innately elevated levels of Toll like receptor 4 (TLR4) and monocyte chemotactic protein 1 (MCP 1) that colocalize in neurons from the central nucleus of the amygdala (CeA) and ventral tegmental area (VTA). CCL2 addiction intoxication 25567426 Infusion of amplicons for TLR4 or MCP 1 siRNA into the CeA or VTA from the P rats inhibited target gene expression and blunted binge drinking. CCL2 drug alcohol 25567426 A similarly delivered amplicon for scrambled siRNA did not inhibit TLR4 or MCP 1 expression nor reduce binge drinking, identifying a neuronal TLR4/MCP 1 signal that regulates the initiation of voluntary alcohol self administration.

CCL2 drug alcohol 24772072 CCL2 ethanol interactions and hippocampal synaptic protein expression in a transgenic mouse model. CCL2 drug alcohol 24772072 Recent data show that ethanol induces glial cells of the brain to produce elevated levels of neuroimmune factors including CCL2, a key innate immune chemokine. CCL2 drug alcohol 24772072 Depending on the conditions of ethanol exposure, the upregulated levels of CCL2 can be transient or persistent and outlast the period of ethanol exposure. CCL2 drug alcohol 24772072 Importantly, results indicate that the upregulated levels of CCL2 may lead to CCL2 ethanol interactions that mediate or regulate the effects of ethanol on the brain. CCL2 drug alcohol 24772072 To investigate this possibility, we are studying effects of chronic ethanol on hippocampal synaptic function in a transgenic mouse model that expresses elevated levels of CCL2 in the brain through enhanced glial expression, a situation know to occur in alcoholics. CCL2 drug alcohol 24772072 Both CCL2 and ethanol have been reported to alter synaptic function in the hippocampus. CCL2 drug alcohol 24772072 In the current study, we determined if interactions are evident between CCL2 and ethanol at the level of hippocampal synaptic proteins. CCL2 drug alcohol 24772072 Results show modest effects of both ethanol exposure paradigms on the level of synaptic proteins in the hippocampus of CCL2 transgenic mice compared with their non transgenic littermate controls, consistent with ethanol CCL2 interactions. CCL2 drug alcohol 24772072 No evidence of toxic effects of CCL2 or CCL2 ethanol interactions was observed. CCL2 drug alcohol 24772072 Taken together, these results support the idea that ethanol induced astrocyte production of CCL2 can result in neuroadaptive changes that interact with the actions of ethanol. CCL2 drug alcohol 24766056 In patients with mild ALD, 1 week of alcohol withdrawal was sufficient to decrease expression level of total macrophage markers in the adipose tissue, to orient adipose tissue macrophages (ATM) towards an anti inflammatory M2 phenotype and to decrease the mRNA expression of cytokines/chemokines (IL18, CCL2, osteopontin, semaphorin 7A).

CCL2 drug alcohol 16105698 To test the hypothesis that chemokines exhibit previously undiscovered pleiotropic effects important for the behavioral actions of ethanol, we studied mutant mice with deletion of the Ccr2, Ccr5, Ccl2 or Ccl3 genes. CCL2 drug alcohol 16105698 Deletion of Ccr2, Ccl2 (females) or Ccl3 in mice resulted in lower preference for alcohol and consumption of lower amounts of alcohol in a two bottle choice test as compared with wild type mice.

GRM1 drug alcohol 24467847 In the past, the detailed study of the functional relevance of mGluR1 for alcoholism related behaviors in animal models was hampered by the poor solubility and non specific side effects of available inhibitors; however, the advent of the highly potent and soluble mGluR1 negative allosteric modulator JNJ 16259685 [(3,4 Dihydro 2H pyrano[2,3 b]quinolin 7 yl) (cis 4 methoxycyclohexyl) methanone] has instigated a re examination of the role for this mGluR subtype in mediating the behavioral effects of alcohol.

GRM1 addiction intoxication 23966068 The effects of co infusing mGluR1 and PLC inhibitors were additive, whereas those of coinhibiting mGluR5 and PLC were not, indicating that the efficacy of mGluR1 blockade to lower binge intake involves a pathway independent of PLC activation.

GRM1 drug cocaine 21749491 Blocking cannabinoid receptor 1 (CB(1)) reduced mGluR1 LTP in the saline treated but not cocaine withdrawn group. GRM1 drug cannabinoid 21749491 Additionally, increasing endocannabinoid (eCB) levels abolished mGluR1 LTP in the saline but not cocaine withdrawn group. GRM1 drug cocaine 21749491 Additionally, increasing endocannabinoid (eCB) levels abolished mGluR1 LTP in the saline but not cocaine withdrawn group. GRM1 drug cocaine 21749491 However, CB(1) and CB(2) protein levels were increased in the amygdala of cocaine withdrawn rats while mGluR1 and mGluR5 remained unchanged. GRM1 drug cocaine 21749491 These data suggested that the mechanisms underlying the diminished mGluR1 LTP in cocaine withdrawn rats involve an altered GABAergic synaptic inhibition mediated by modulation of downstream eCB signaling. GRM1 drug cocaine 21521425 The present study evaluated the contribution of metabotropic glutamate receptor subtype 1 (mGluR1) and α amino 3 hydroxy 5 methyl 4 isoxazolepropionic acid (AMPA)/kainate receptor populations to drug context induced reinstatement of cocaine seeking behavior.

GRM1 drug cocaine 21521425 Cocaine seeking behavior (non reinforced active lever pressing) was then assessed in the previously cocaine paired and extinction contexts after JNJ16259685 (mGluR1 antagonist: 0.0, 0.6, or 30 pg/0.3 µl/hemisphere) or CNQX (AMPA/kainate receptor antagonist: 0.0, 0.03, or 0.3 µg/0.3 µl /hemisphere) administration into the NAC core, medial or lateral NAC shell, or the ventral caudate putamen (vCPu, anatomical control). GRM1 addiction relapse 21521425 Cocaine seeking behavior (non reinforced active lever pressing) was then assessed in the previously cocaine paired and extinction contexts after JNJ16259685 (mGluR1 antagonist: 0.0, 0.6, or 30 pg/0.3 µl/hemisphere) or CNQX (AMPA/kainate receptor antagonist: 0.0, 0.03, or 0.3 µg/0.3 µl /hemisphere) administration into the NAC core, medial or lateral NAC shell, or the ventral caudate putamen (vCPu, anatomical control). GRM1 drug cocaine 21521425 Thus, glutamate mediated changes in drug context induced motivation for cocaine involve distinct neuropharmacological mechanisms within the core and shell subregions of the NAC, with the stimulation of mGlu1 and AMPA/kainate receptors in the NAC core and the stimulation of AMPA/kainate, but not mGlu1, receptors in the NAC shell being necessary for this phenomenon.

GRM1 drug cocaine 19128205 Similarly, the mGluR1/5 antagonists, 2 methyl 6 (phenylethynyl)pyridine and 3 [2 methyl 4 thiazolyl)ethynyl]pyridine, have shown to be effective in preclinical models of cocaine addiction. GRM1 addiction addiction 19128205 Similarly, the mGluR1/5 antagonists, 2 methyl 6 (phenylethynyl)pyridine and 3 [2 methyl 4 thiazolyl)ethynyl]pyridine, have shown to be effective in preclinical models of cocaine addiction. GRM1 drug alcohol 18838071 Antagonists of group I mGlu receptors, such as MTEP ([(2 methyl 1,3 thiazol 4 yl) ethynyl] pyridine, mGlu5 receptor) or EMQMCM (3 ethyl 2 methyl quinolin 6 yl (4 methoxy cyclohexyl) methanone methanesulfonate, mGlu1 receptor), caused similar effects to acamprosate. GRM1 drug psychedelics 18419818 The aim of the present study was to investigate the effect of repeated intermittent MDMA administration upon gene transcript expression of the glutamate transporters (EAAT1, EAAT2 1, EAAT2 2), the glutamate receptor subunits of AMPA (GluR1, GluR2, GluR3), the glutamate receptor subunits of NMDA (NR1, NR2A and NR2B), as well as metabotropic glutamate receptors (mGluR1, mGluR2, mGluR3, mGluR5) in six different brain regions.

GRM1 addiction reward 18164577 The purpose of this work was to examine the role of mGlu1 receptor antagonism in the maintenance of ethanol self administration and the self administration of an alternate nondrug reward, sucrose. GRM1 drug alcohol 18164577 Male alcohol preferring inbred rats were trained to self administer ethanol (15% vol/vol) versus water on a concurrent schedule of reinforcement, and the effect of the mGlu1 receptor antagonist JNJ16259685 (0.1 1.0mg/kg intraperitoneal [IP]) was evaluated on self administration. GRM1 addiction reward 18164577 Male alcohol preferring inbred rats were trained to self administer ethanol (15% vol/vol) versus water on a concurrent schedule of reinforcement, and the effect of the mGlu1 receptor antagonist JNJ16259685 (0.1 1.0mg/kg intraperitoneal [IP]) was evaluated on self administration. GRM1 drug alcohol 18164577 Interestingly, ethanol self administration was more sensitive to mGlu1 receptor antagonism than sucrose self administration as lower JNJ16259685 doses reduced ethanol reinforced responding and motor behavior.

GRM1 drug alcohol 18162077 Emerging evidence indicates that Group I metabotropic glutamate receptors (mGluR1 and mGluR5) differentially regulates ethanol self administration in several rodent behavioral models. GRM1 drug alcohol 18162077 The mGluR1 antagonist, 3,4 dihydro 2H pyrano[2,3]b quinolin 7 yl (cis 4 methoxycyclohexyl) methanone (JNJ 16259685; 0 to 1 mg/kg) and the mGluR5 antagonist, 6 methyl 2 (phenylethynyl) pyridine (MPEP; 0 to 10 mg/kg) dose dependently reduced ethanol break point. GRM1 drug alcohol 18162077 Thus, the reduction in ethanol break point by mGluR1 antagonism was probably a result of a motor impairment.

GRM1 drug opioid 16793067 The aims of the present study were to assess: (i) the role of mGlu1 and mGlu5 receptors in inflammatory pain using selective antagonist EMQMCM, 1.25 5 mg/kg, as the mGlu1 receptor antagonist, and MPEP or MTEP, 2.5 10 mg/kg, as mGlu5 receptor antagonist; (ii) the possible interaction between mGlu1 and mGlu5 receptor antagonists and morphine; and (iii) whether tolerance develops to the analgesic effects of these antagonists after prolonged treatment. GRM1 drug opioid 16793067 In the present study, the suppressive effect on formalin induced pain behaviour was much stronger when mGlu1 and mGlu5 receptor antagonists were co injected compared to administration of a single antagonist, but this effect was not seen when mGlu receptor antagonist was co administered with morphine. GRM1 drug cannabinoid 16723539 In THC tolerant mice, an increase of the basal release probability was found at PF PC synapses, in parallel with a facilitation of slow mGluR1 (metabotropic glutamate receptor type 1) mediated excitatory postsynaptic currents and a reduced sensitivity to the inhibitory effects of the CB1R agonist CP55,940 [( ) cis 3 [2 hydroxy 4 (1,1 dimethylheptyl)phenyl] trans 4 (3 hydroxypropyl)cyclohexanol]. GRM1 drug cannabinoid 16554472 First, a combined activation of group I mGluRs (mGluR1 and mGluR5) induces a transient depression that is cannabinoid 1 receptor dependent. GRM1 drug cannabinoid 16301180 Endocannabinoid release and LTD induction both depend upon activation of the metabotropic glutamate receptor mGluR1, require postsynaptic calcium increases, are synapse specific, and have a similar dependence on the associative activation of PF and climbing fiber synapses.

GRM1 drug alcohol 16292590 Effects of mGluR1, mGluR2/3, and mGluR5 antagonists were then tested on parameters of ethanol self administration behavior. GRM1 drug alcohol 15717208 After the establishment of operant ethanol self administration, subjects were treated with various metabotropic glutamate receptor (mGluR) subtype antagonists immediately prior to experimental sessions: the mGluR5 antagonist MPEP (1, 3, and 10 mg/kg); the mGluR2 3 antagonist LY 341495 (1, 3, and 10 mg/kg); and the mGluR1 antagonist CPCCOEt (1, 3, and 10 mg/kg).

GRIN1 drug cocaine 32751823 We found an up regulation of the accumbal levels of GluN1 and GluN2A following cocaine self administration that was paralleled by an increase of Munc13 and RIM1 levels. GRIN1 drug cocaine 32751823 At the same time, we also demonstrated that different conditions of cocaine abstinence abolished changes in NMDA receptor subunits (except for higher GluN1 levels after cocaine abstinence with extinction training), while an increase in the Munc13 concentration was shown in rats housed in an enriched environment. GRIN1 addiction reward 32593543 Then, using small interfering RNAs (siRNAs), we tested the effect of tVTA downregulation of the GluN1 subunit of the NMDA receptor on reward and locomotor activity. GRIN1 addiction reward 32593543 On the other hand, a reduction in GluN1 subunits used a marked decrease in operant responding for ICSS, but failed to alter ICSS reward and the reward enhancing effect of PPPA.

GRIN1 drug alcohol 32415404 Western blot analysis indicated that GluN1 expression in the hippocampus of alcohol drinking group was lower than that in the control group, while the expression of GluN1 was increased in MMP 9 overexpressing mice. GRIN1 drug alcohol 32062779 We aimed to investigate whether ethanol (EtOH) and acetaldehyde (AcH) can affect glutamate and its receptors GluN1 and GluA1 in the hippocampus of Aldh2 knockout (Aldh2 KO) and C57BL/6N (wild type (WT)) mice. GRIN1 addiction intoxication 32062779 Together, these in vivo and ex vivo data suggest that EtOH and AcH decrease extracellular glutamate in the hippocampus of mice with a concomitant decrease in GluN1 and GluA1 subunits, but these effects require relatively high concentrations and may, therefore, explain the consequences of EtOH intoxication. GRIN1 drug alcohol 31978422 Results showed that the mRNA levels of GluN2A but not GluN1 in NAc are higher after ethanol CPP.

GRIN1 drug amphetamine 30056065 In this study, we measured the effects of single dose injections of modafinil and METH on the protein levels of acetylated histone H3 (H3ac) and H4ac, deacetylases HDAC1 and HDAC2, and of the NMDA subunit GluN1 in the medial PFC (mPFC) of mice euthanized 1 h after drug administration. GRIN1 drug amphetamine 30056065 Acute modafinil and METH injections caused similar effects on total histone acetylation, increasing H3ac and decreasing H4ac, and they also increased HDAC1, HDAC2 and GluN1 protein levels in the mouse mPFC. GRIN1 drug amphetamine 30056065 Analysis of histone 3/4 enrichment at specific promoters revealed: i) distinct effects of the drugs on histone 3 acetylation, with modafinil increasing H3ac at Drd1 and Adra1b promoters, but METH increasing H3ac at Adra1a; ii) distinct effects on histone 4 acetylation enrichment, with modafinil increasing H4ac at the Drd2 promoter and decreasing it at Hrh1, but METH increasing H4ac at Drd1; iii) comparable effects of both psychostimulants, increasing H3ac at Drd2, Hcrtr1, and Hrh1 promoters, decreasing H3ac at Hrh3, increasing H4ac at Hcrtr1, and decreasing H4ac at Hcrtr2, Hrh3, and Grin1 promoters. GRIN1 drug amphetamine 30056065 Interestingly, only METH altered mRNA levels of genes with altered histone acetylation status, inducing increased expression of Drd1a, Adra1a, Hcrtr1, and Hrh1, and decreasing Grin1. GRIN1 addiction addiction 29766293 Data obtained using Western blotting technique showed a significant increase in the level of GluN1 and GluN2B, but not in GluN2A subunits in all the three regions (mPFC, lPFC, and OFC) of men whom suffered from addiction as compared to the appropriate controls. GRIN1 addiction addiction 29766293 These findings showed a novel role for GluN1, GluN2B subunits, rather than the GluN2A subunit of NMDARs, in the pathophysiology of addiction and suggested their role in the drug induced plasticity of NMDARs. GRIN1 drug amphetamine 29247759 METH treated mice also showed i) decreased levels of total H3ac and H4ac, and increased levels of 5 mC, ii) decreased H3ac enrichment at promoters of Drd2, Hcrtr1/2, Hrh1 and Grin1, and increased H4ac enrichment at Drd1, Hrh1 and Grin1, iii) increased mRNA of Drd1a, Grin1 and Gria1. GRIN1 addiction addiction 29234834 One day after the final self administration session, the rats were euthanized and the dmPFC was removed for quantification of mRNA expression of critical glutamatergic signaling genes, Homer2, Grin1, and Dlg4, as these genes and brain region have been previously implicated in addiction, learning, and memory. GRIN1 drug cocaine 29234834 Lastly, Homer2, Grin1, and Dlg4 mRNA were impacted by both duration and mode of cocaine exposure.

GRIN1 drug opioid 24223972 Sub acute morphine administration resulted in a decrease of NMDAR1 and Arrb2 whereas during longer opioid treatment the expression NMDAR1 and Arrb2 mRNA increased again to baseline values. GRIN1 drug psychedelics 24223972 Coadministration of s ketamine or clonidine resulted in a reversal of the mechanical hyperalgesia and inhibited the normalization of NMDAR1 mRNA expression but had no effect on the expression of Arrb2 mRNA. GRIN1 drug cocaine 24102978 Conversely, in cocaine treated animals, stress dynamically altered the glutamatergic synapse by: (1) enhancing the presynaptic vesicular mediators of glutamate release; (2) reducing the transporters responsible for glutamate clearance; (3) increasing the postsynaptic responsiveness of the N methyl D aspartate subunit GluN1; and (4) causing hyperresponsive spines as evidenced by increased activation of the postsynaptic cdc42 Pak pathway.

GRIN1 drug cocaine 12105087 The aim of the present work was to study the time course effects in levels of mRNA encoding N methyl d aspartate receptor subunit 1 (NMDAR1) after long term cocaine self administration (1 mg/kg/ injection) and its extinction using a yoked box procedure. GRIN1 drug cocaine 12105087 NMDAR1 content was measured by quantitative in situ hybridization histochemistry in prefrontal cortex, caudate putamen, nucleus accumbens, olfactory tubercle, and piriform cortex immediately after cessation of the last session of cocaine self administration (Day 0) and 1, 5, and 10 days after the extinction period. GRIN1 drug cocaine 12105087 The results show that long term cocaine self administration and its extinction alter NMDAR1 gene expression in these forebrain regions, and that the changes depend upon the brain region examined and the type of cocaine administration (contingent, noncontingent, and saline). GRIN1 drug cocaine 12105087 Compared to saline and noncontingent cocaine administration, contingent cocaine produced an up regulation in NMDAR1 gene expression on Day 0 in all the brain regions analyzed. GRIN1 drug cocaine 12105087 NMDAR1 levels of contingent animals decreased progressively in the absence of cocaine, and the decrement persisted 10 days after the extinction of cocaine self administration behavior in all the forebrain areas, with the exception of olfactory tubercle. GRIN1 drug cocaine 12105087 In contrast, noncontingent cocaine administration did not produce any change in NMDAR1 gene expression on Day 0, and extinction resulted in an increase of NMDAR1 mRNA content on Days 1 and 5 and returned to control (saline) values on Day 10. GRIN1 drug cocaine 12105087 These results suggest that an interaction between environmental stimuli and the pharmacological action of cocaine during drug self administration and its extinction may represent an important factor in the regulation of cocaine effects on NMDAR1 gene expression. GRIN1 drug opioid 11858765 Single dose of morphine was followed by a decrease in gene expression of glutamate receptor subunit NMDAR1 in the adrenal gland. GRIN1 drug amphetamine 10510180 Withdrawal from repeated amphetamine administration reduces NMDAR1 expression in the rat substantia nigra, nucleus accumbens and medial prefrontal cortex. GRIN1 addiction withdrawal 10510180 Withdrawal from repeated amphetamine administration reduces NMDAR1 expression in the rat substantia nigra, nucleus accumbens and medial prefrontal cortex. GRIN1 drug amphetamine 10510180 This study determined whether expression of the NMDAR1 subunit of the NMDA receptor is altered by repeated amphetamine administration. GRIN1 drug amphetamine 10510180 We quantified NMDAR1 mRNA (using in situ hybridization with 35S labelled oligonucleotide probes) and immunolabelling (using immunocytochemistry with 35S labelled secondary antibodies) in rat ventral midbrain, nucleus accumbens and prefrontal cortex after 3 or 14 days of withdrawal from five daily injections of saline or amphetamine sulphate (5 mg/kg/day). GRIN1 addiction withdrawal 10510180 We quantified NMDAR1 mRNA (using in situ hybridization with 35S labelled oligonucleotide probes) and immunolabelling (using immunocytochemistry with 35S labelled secondary antibodies) in rat ventral midbrain, nucleus accumbens and prefrontal cortex after 3 or 14 days of withdrawal from five daily injections of saline or amphetamine sulphate (5 mg/kg/day). GRIN1 addiction withdrawal 10510180 No changes in NMDAR1 expression were observed after 3 days of withdrawal, whereas significant decreases were observed in all regions after 14 days. GRIN1 drug cocaine 10349849 GluR1, GluR2/3, and NMDAR1 subunits of glutamate receptors were quantified from immunoblots in these brain nuclei in rats at 24 h and 3 weeks after discontinuing 1 week of daily cocaine injections. GRIN1 addiction withdrawal 10349849 Conversely, sensitized animals showed a significant increase in NMDAR1 and GluR1 levels in the ventral tegmental area at 1 day but not at 3 weeks of withdrawal. GRIN1 drug alcohol 8912402 Furthermore, since there is evidence that eliprodil produces its pharmacological actions through a specific inhibition of NMDAR1 and/or NMDAR2B subunits, these data may indicate that certain NMDA receptor subunits may be of particular importance for the mediation of seizure activity following the discontinuation of chronic ethanol exposure. GRIN1 drug cocaine 8613793 By immunoblotting procedures using subunit specific antibodies, we found that repeated, but not acute, cocaine treatment increased the levels of immunoreactivity of GluR1 (an AMPA receptor subunit) and NMDAR1 (an NMDA receptor subunit) in the ventral tegmental area (VTA), a nucleus containing mesolimbic DA neurons. GRIN1 drug cocaine 8613793 Unlike cocaine, morphine, and stress, repeated treatment with other psychotropic drugs (haloperidol, raclopride, sertraline, and desipramine) that lack reinforcing or sensitizing properties did not regulate GluR1 or NMDAR1 subunit levels in the VTA. GRIN1 drug opioid 8613793 Unlike cocaine, morphine, and stress, repeated treatment with other psychotropic drugs (haloperidol, raclopride, sertraline, and desipramine) that lack reinforcing or sensitizing properties did not regulate GluR1 or NMDAR1 subunit levels in the VTA.

GRIN1 drug alcohol 8869159 It was found that long term, but not short term, ethanol exposure increased levels of immunoreactivity of the NMDAR1 subunit, an obligatory component of NMDA glutamate receptors, and of the GluR1 subunit, a component of many AMPA glutamate receptors; but at the same time, long term ethanol exposure decreased immunoreactivity levels of the alpha 1 subunit of the GABAA receptor complex. GRIN1 drug alcohol 8133290 Chronic ingestion of ethanol up regulates NMDAR1 receptor subunit immunoreactivity in rat hippocampus. GRIN1 drug alcohol 8133290 We examined the effects of chronic ethanol exposure on the levels of N methyl D aspartate receptor subunit 1 (NMDAR1) protein, an essential component of N methyl D aspartate glutamate receptors, in rat brain. GRIN1 drug alcohol 8133290 By immunoblotting procedures using a specific antibody for the NMDAR1 subunit, we found that ethanol dramatically up regulated (by 65%) NMDAR1 immunoreactivity in the hippocampus but not in the nucleus accumbens, cerebral cortex, or striatum. GRIN1 drug alcohol 8133290 Increased NMDAR1 subunit levels in the hippocampus after chronic ethanol exposure may represent an important neurochemical substrate for some of the features associated with ethanol dependence and withdrawal.

GRIN1 drug alcohol 8974321 In addition, we examined the levels of NMDAR1 receptor subunit mRNAs since chronic ethanol administration results in increased levels of [3H]MK 801 recognition sites on NMDA receptors. GRIN1 drug alcohol 8974321 NMDAR1 receptor subunit mRNAs were not altered following chronic ethanol exposure in rat cortex or hippocampus.

GABRA2 drug alcohol 30555510 Among its many effects, alcohol consumption reduces anxiety via the inhibitory neurotransmitter GABA, most likely acting upon receptors containing the α 2 subunit (Gabra2). GABRA2 addiction intoxication 30555510 Because βE works via GABA signaling to reduce anxiety, we sought to determine whether sexually dimorphic binge drinking behavior in βE deficient mice is coupled with differences in CNS Gabra2 expression. GABRA2 addiction intoxication 30555510 Following a binge test on day 4, limbic tissue was collected and frozen for subsequent qRT PCR analysis of Gabra2 mRNA expression. GABRA2 drug alcohol 30555510 Genotype alone had no effect on alcohol consumption or drug induced increase in Gabra2 expression. GABRA2 addiction intoxication 30555510 In contrast, βE expression had bi directional effects in females: in wildtypes, Gabra2 mRNA was reduced by binge EtOH consumption, while EtOH increased expression in βE / females to levels commensurate with drug naïve βE +/+ females.

GABRA2 addiction addiction 30138693 The genetic association of Gabra2 haplotypes with cocaine addiction appears to be evident primarily in individuals who had experienced childhood trauma. GABRA2 drug cocaine 30138693 Given this association of childhood trauma, cocaine abuse and the Gabra2 haplotypes, we have explored in a mouse model of early life adversity (ELA) whether such events influence the behavioral effects of cocaine and if, as suggested by the human studies, α2 GABAARs in the nucleus accumbens (NAc) are involved in these perturbed behaviors.

GABRA2 addiction reward 29528673 GABRA2, the gene encoding the α2 subunit of the GABAA receptor, potentially plays a role in the etiology of problematic drinking, as GABRA2 genotype has been associated with subjective response to alcohol and other alcohol related reward processes. GABRA2 drug alcohol 29528673 The GABRA2 gene has also been associated with illicit drug use, but the extent to which associations with drug use are independent of associations with alcohol use remains unclear, partly because most previous research has used a cross sectional design that cannot discriminate comorbidity at the between person level and co occurrence within persons.

IL2 addiction relapse 28126360 In a longitudinal design we measured plasma levels of the pro inflammatory interleukin 6 (IL 6), the soluble alpha (Tac) subunit of the interleukin 2 receptor (sIL 2r), and the circulating soluble form of the intercellular adhesion molecule one (sICAM 1), in 79 help seeking UHR individuals (13 25years of age). IL2 drug alcohol 27699959 The results showed that alcohol intoxication increased the plasma levels of several cytokine and chemokine [interferon γ, interleukin (IL) 10, IL 17A, IL 1β, IL 2, IL 4, IL 6, IL 8, fractalkine, monocyte chemoattractant protein 1 (MCP 1) and macrophage inflammatory protein 1α (MIP 1α)] and the upregulation of TLR4 mRNA levels occurred in intoxicated females, while elevation of colony stimulating factor was only observed in the plasma of males.

IL2 addiction intoxication 27455577 It was established in experiments on noninbred albino rats that the acute intoxication with methanol (1.0 LD50) decreased cellular and humoral immune responses, Th2 lymphocyte activity (to a greater extent as compared to the function of Th1 cells), reduced the blood concentration of immunoregulatory (IFN g, IL 2, IL 4) and proinflammatory (TNF, IL 1b, IL 6) cytokines on the average by 36.5% (p < 0.05), and did not affect the content of anti inflammatory cytokines (IL 10, IL 13). IL2 drug alcohol 27455577 Methanol antidote 4 methylpyrazole (non competitive inhibitor of alcohol dehydrogenase) administered upon acute intoxication with methanol at a dose of 1.0 DL50 partially reduces the intoxication induced suppression of humoral and cellular immune response, activity of T helper cells, and production of IL 4 and restores blood levels of TNF, IL 1b, IFN γ, IL 4, IL 2, IL 6 to the control values.

IL2 drug opioid 18502094 Whereas IL 1alpha, IL 2, and TNF alpha are all proinflammatory cytokines, morphine exposure has individualized effects on their blood to brain transport. IL2 drug opioid 18294814 An altered Th1/Th2 balance, characterized by reduced IL 4, IFN gamma and TNF alpha but normal IL 2 levels, was present in untreated heroin addicted subjects, while the Th1/Th2 balance was well conserved in the methadone and buprenorphine groups.

IL2 addiction intoxication 15718389 Two days after injury, a significant increase in blood Cort levels and suppression of MLN T cell proliferation and IL 2 production was observed in rats receiving combined insult of EtOH intoxication and burn injury compared with rats receiving EtOH intoxication or burn injury alone. IL2 drug opioid 15055740 Similarly, production of IL 2, IL 10 and IFNgamma was higher in the group of heroin addicts than in healthy controls. IL2 drug opioid 14741432 We had previously shown that chronic morphine treatment in vivo and in vitro decreases IL 2 and IFNgamma (Th1) protein levels and increases IL 4 and IL 5 (Th2) protein levels in a time dependent manner.

IL2 drug opioid 11021983 The results clearly show that IL 2 receptors present in LC mediate descending inhibition of the spinal nociception, which may couple with the activation of opioid receptors on LC neurons. IL2 drug opioid 10936512 In this study, it was shown that injection of an equianalgesic dose of buprenorphine (related to morphine) into the ventral caudal PAG did not alter splenic NK cell, T cell, and macrophage functions, whereas morphine significantly (p<0.001) suppressed splenic NK cell cytotoxic activity (14 50% reduction), splenic and thymic T cell proliferation to concanavalin A (Con A, 43 76% reduction), antiTCR (T cell receptor) (85% reduction) and IL 2 (36 48% reduction), and macrophage functions including nitric oxide (36 41% reduction) and TNF alpha production (26%), and phagocytosis of Candida albicans (39%).

DRD1 drug opioid 31192519 Heroin delay discounting and impulsivity: Modulation by DRD1 genetic variation. DRD1 addiction addiction 31192519 Dopamine D1 receptors (encoded by DRD1) are implicated in drug addiction and high risk behaviors. DRD1 drug opioid 31192519 DRD1 variants have been linked with increased DD (in healthy volunteers) and opioid abuse. DRD1 drug opioid 31192519 Substance use, DD, and genotype data (DRD1 rs686 and rs5326, DRD3 rs6280, COMT rs4680) were obtained from 106 current heroin users. DRD1 drug opioid 31192519 DRD1 rs686 (A/A, n = 25; G/A, n = 56; G/G, n = 25) was linearly related to the difference in heroin DD (area under the curve; AUC) between the heroin satiation and withdrawal conditions; specifically, G/G homozygotes had a significantly smaller (satiation minus withdrawal) AUC difference score had higher drug use impulsivity questionnaire scores, relative to A/A homozygotes, with G/A intermediate. DRD1 addiction withdrawal 31192519 DRD1 rs686 (A/A, n = 25; G/A, n = 56; G/G, n = 25) was linearly related to the difference in heroin DD (area under the curve; AUC) between the heroin satiation and withdrawal conditions; specifically, G/G homozygotes had a significantly smaller (satiation minus withdrawal) AUC difference score had higher drug use impulsivity questionnaire scores, relative to A/A homozygotes, with G/A intermediate. DRD1 drug opioid 31192519 DRD1 rs686 modulated the difference in heroin DD score between pharmacological states and was associated with drug use impulsivity. DRD1 drug opioid 31192519 These data support a role of DRD1 in opioid DD and impulsive behaviors.

DRD1 drug cocaine 30952156 Dopamine receptor D1 (DRD1) expression was also significantly reduced in the orbitofrontal cortex of high cocaine escalating rats. DRD1 drug alcohol 30516420 The result obtained with this model point out that the relation among high fat diet consumption and alcohol intake appears to depend on the presence or absence of the diet when alcohol intake is evaluated, and that an imbalance in the mesocorticolimbic dopaminergic pathway, observed by the transcriptional regulation of the dopamine receptors (Drd1/Drd2) and GABAB receptors subunit (Gabbr1/Gabbr2), can be driving the alcohol intake. DRD1 drug opioid 30268777 The mRNA and protein level of DRD1 increased in the VTA, NAC and amygdala of opioid abusers. DRD1 drug cocaine 30210305 When investigating if the reduced level of glutamate co release from DA neurons caused a detectable post synaptic effect on MSNs, patch clamp analysis identified an enhanced baseline AMPA/NMDA ratio in DA receptor subtype 1 (DRD1) expressing accumbal MSNs which occluded the effect of cocaine on synaptic transmission. DRD1 drug amphetamine 30056065 Whole cell patch clamp in transgenic BAC Drd1a tdTomato mice showed that METH, but not modafinil, induced paired pulse facilitation of EPSCs, suggesting reduced presynaptic probability of glutamate release onto layer V pyramidal neurons. DRD1 drug amphetamine 30056065 Analysis of histone 3/4 enrichment at specific promoters revealed: i) distinct effects of the drugs on histone 3 acetylation, with modafinil increasing H3ac at Drd1 and Adra1b promoters, but METH increasing H3ac at Adra1a; ii) distinct effects on histone 4 acetylation enrichment, with modafinil increasing H4ac at the Drd2 promoter and decreasing it at Hrh1, but METH increasing H4ac at Drd1; iii) comparable effects of both psychostimulants, increasing H3ac at Drd2, Hcrtr1, and Hrh1 promoters, decreasing H3ac at Hrh3, increasing H4ac at Hcrtr1, and decreasing H4ac at Hcrtr2, Hrh3, and Grin1 promoters. DRD1 drug amphetamine 30056065 Interestingly, only METH altered mRNA levels of genes with altered histone acetylation status, inducing increased expression of Drd1a, Adra1a, Hcrtr1, and Hrh1, and decreasing Grin1. DRD1 addiction reward 29909784 The results demonstrated a regional specificity with which the functional polymorphism rs686 of the D1 dopamine receptor (DRD1) gene and Taq1A of the ANKK1 gene influenced medial and lateral OFC activation during reward anticipation, respectively. DRD1 drug alcohol 29909784 Importantly, our path model revealed a significant indirect relationship between the rs686 of the DRD1 gene and early onset of alcohol misuse through a medial OFC × VS interaction.

BAX drug opioid 25846801 Various regimens of morphine reduced TWI, cortisol levels, Bax activity, caspase 3, caspase 9, TNF α, and IL 1β and lipid peroxidation. BAX drug psychedelics 25748203 In addition, ketamine induced the expression of Bax, cytochrome c and capase 3, but inhibited the expression of NF κB and bcl 2. BAX drug opioid 25712644 The results showed that morphine significantly increased lipid peroxidation, mitochondrial GSH level, concentration of Bax; caspase 3 and caspase 9 activities while decreasing Bcl 2 concentration. BAX drug alcohol 25623404 Apoptotic cell death and temporal expression of apoptotic proteins Bcl 2 and Bax in the hippocampus, following binge ethanol in the neonatal rat model. BAX addiction intoxication 25623404 Apoptotic cell death and temporal expression of apoptotic proteins Bcl 2 and Bax in the hippocampus, following binge ethanol in the neonatal rat model. BAX addiction intoxication 25623404 Western blot analysis determined expression of pro apoptotic Bax and anti apoptotic Bcl 2, 12, 24, and 48 hours after binge EtOH exposure on PN6. BAX addiction intoxication 25623404 Binge EtOH exposure on PN6 resulted in a significant increase in expression of Bcl 2 and the Bcl 2:Bax ratio in the CA1/DG region at 24 hours after EtOH exposure on PN6. BAX addiction intoxication 25623404 This finding may be explained in part by changes in the Bcl 2:Bax ratio after a single binge EtOH exposure. BAX drug opioid 25597171 Group II also exhibited a significantly reduced epididymal perm count (P < 0.05) and remarkably upregulated expressions of Bax and Caspase 3 in comparison with group I. Morphine might increase testicular cell apoptosis and reduce sperm concentration by upregulating the expressions of Bax and Caspase 3 in the rat model of morphine tolerance. BAX drug amphetamine 25463524 In addition, methamphetamine enhanced expression of anti apoptotic protein Bcl 2 and reduced pro apoptotic protein Bax levels in the ventral hippocampus, suggesting a mechanism for reducing cell death. BAX drug amphetamine 25463524 These data reveal that alterations in Bcl 2 and Bax levels by methamphetamine were not associated with enhanced Akt expression. BAX drug opioid 24959978 In this study, we investigated the effects of morphine induced conditioned place preference (CPP) in the presence and absence of stress on the changes of apoptotic factors (Bax/Bcl 2 ratio, caspase 3 activation and PARP degradation) in the MCL system. BAX addiction reward 24959978 In this study, we investigated the effects of morphine induced conditioned place preference (CPP) in the presence and absence of stress on the changes of apoptotic factors (Bax/Bcl 2 ratio, caspase 3 activation and PARP degradation) in the MCL system. BAX drug opioid 24959978 In the morphine treated animals, AS and SS increased apoptotic factors remarkably (except for the Bax/Bcl 2 ratio after AS and SS in the Str and caspase 3 activation after AS in the NAc) and also decreased conditioning scores. BAX drug opioid 24906198 We found that chronic exposure to morphine impaired spatial and aversive memory and remarkably suppressed the expression of Bcl 2, but Bax expression remained constant. BAX addiction aversion 24906198 We found that chronic exposure to morphine impaired spatial and aversive memory and remarkably suppressed the expression of Bcl 2, but Bax expression remained constant. BAX drug opioid 24906198 Both voluntary and treadmill exercise alleviated memory impairment, increased the expression of Bcl 2 protein, and only the later suppressed the expression of Bax protein in morphine dependent animals. BAX drug opioid 24281942 In the HPC, morphine significantly increased the ratio of Bax/Bcl 2, caspases 3, and PARP by the lowest dose (0.5 mg/kg), but, in the VTA, a considerable increase was seen in the dose of 5 mg/kg; promotion of apoptotic factors in the HPC and VTA insinuates that morphine can affect the molecular mechanisms that interfere with apoptosis through different receptors. BAX drug opioid 24096212 In the NAc, morphine significantly increased the Bax/Bcl 2 ratio, caspase3 and PARP in the lowest dose (0.5mg/kg) but in the PFC considerable increase was seen in dose of 5mg/kg. BAX drug amphetamine 23975636 METH activates the upregulation of the Bax, cytochrome c, cleavage caspase 9 and 3 proteins, and downregulation of Bcl XL protein in cascade. BAX drug psychedelics 23508639 There was a significant increase in Bax protein expression in the MDMA+SCH group and a significant decrease in Bcl 2 protein expression in the MDMA+SCH group (p<0.05). BAX drug psychedelics 23508639 A2A receptors have a role in the apoptotic effects of MDMA via the Bax and Bcl 2 pathways. BAX drug opioid 23319379 Bax and cleaved caspase 3 were positive only in the heroin subjects. BAX addiction reward 27385959 In this study, the effects of acute and subchronic stress on the changes in apoptotic factors (Bax/Bcl 2 ratio, caspase 3 activation and PARP degradation) in the HYP and HIP during conditioned place preference (CPP) paradigm were evaluated. BAX drug opioid 27385959 On the other hand, in the HIP, Bax/Bcl 2 ratio in saline treated animals increased significantly during AS and SS, while in morphine treated animals this ratio did not have any significant alteration during AS and was decreased during SS compared with morphine control group. BAX drug opioid 23262244 Upregulated Bim translocated to mitochondria and Bax was activated under heroin treatment. BAX drug amphetamine 23056363 We also evaluated the striatal expression of the pro apoptotic BAX and anti apoptotic Bcl 2 proteins, which are known to mediate methamphetamine induced apoptotic effects. BAX drug amphetamine 23056363 Modafinil also counteracted the decrease in tyrosine hydroxylase and dopamine transporter levels and prevented methamphetamine induced increases in the pro apoptotic BAX and decreases in the anti apoptotic Bcl 2 protein expression. BAX drug opioid 22210043 Protein expression of cleaved caspase 3 and Bax decreased, whereas Bcl 2 protein levels in hippocampus increased with exogenous H(2)S. Exogenous H(2)S alleviated heroin induced rat hippocampal damage through antioxidant and antiapoptosis effects. BAX drug amphetamine 22174933 Importantly, METH caused decreases in the mitochondrial anti apoptotic protein, Bcl 2, but increases in the pro apoptotic proteins, Bax, Bad and cytochrome c, in a SCH23390 sensitive fashion. BAX drug alcohol 21803053 After 4h, a single dose of ethanol induced upregulation of Bax, release of mitochondrial cytochrome c into the cytosol, activation of caspase 3 and cleavage of poly (ADP ribose) polymerase (PARP 1), all of which promote apoptosis.

BAX addiction dependence 21560342 [The expression of Bcl 2 and Bax in the morphine dependence on male rat germ cell]. BAX drug opioid 21559519 Morphine caused a dramatic decrease in Bcl 2 level but increase in Bax level in wild type microglia, but not in TLR9 deficient microglia. BAX drug opioid 21483469 Enhanced toxicity by Tat and morphine was accompanied by increased numbers of TUNEL positive apoptotic neurons, elevated caspase 3 levels and decreased ratio of anti and pro apoptotic proteins, Bcl2/Bax. BAX drug cocaine 20948987 In microglia, cocaine up regulated the immunoregulatory and pro apoptotic genes IL 1β and BAX. BAX drug alcohol 20090911 Myocardium from ethanol treated mice displayed enhanced Bax, Caspase 3 and decreased Bcl 2 expression, the effect of which with the exception of Caspase 3 was augmented by ADH. BAX drug opioid 18849879 Morphine downregulates proapoptotic factor Bax levels in cultured human neurons. BAX drug amphetamine 17669262 Gene expression profiling of rewarding effect in methamphetamine treated Bax deficient mouse. BAX drug amphetamine 17669262 According to a previous study, Bax was involved in neurotoxicity by methamphetamine, but the function of Bax in rewarding effect has not yet been elucidated. BAX drug amphetamine 17669262 In the present study, we treated chronic methamphetamine exposure in a Bax deficient mouse model and examined behavioral change using a conditioned place preference (CPP) test. BAX addiction reward 17669262 In the present study, we treated chronic methamphetamine exposure in a Bax deficient mouse model and examined behavioral change using a conditioned place preference (CPP) test. BAX addiction reward 17669262 The CPP score in Bax knockout mice was decreased compared to that of wild type mice. BAX drug amphetamine 17669262 Expression of the Tgfbr2 gene was decreased by methamphetamine in Bax knockout mice, and the gene was overexpressed in Bax wild type mice. BAX drug opioid 17384938 This study analyzes the effects of prolonged administration of methadone and withdrawal on sensorimotor and cognitive performance in mice and explores the associated changes in brain expression of proteins regulating the extrinsic (FasL, Fas, and caspase 8) and the mitochondrial (Bcl 2, Bcl x(L), Bad, and Bax) apoptotic pathways. BAX addiction withdrawal 17384938 This study analyzes the effects of prolonged administration of methadone and withdrawal on sensorimotor and cognitive performance in mice and explores the associated changes in brain expression of proteins regulating the extrinsic (FasL, Fas, and caspase 8) and the mitochondrial (Bcl 2, Bcl x(L), Bad, and Bax) apoptotic pathways. BAX drug opioid 17250679 Nonetheless, in street heroin treated cortical neurons, cytochrome c was released, accompanied by a decrease in mitochondrial potential and Bcl 2/Bax. BAX drug amphetamine 17161385 Finally, the METH injection was associated with increased expression of the proapoptotic proteins, Bax and Bid, but with decreased expression of the antideath protein, Bcl2. BAX drug alcohol 17008791 In vitro induction of apoptosis in U937 cells by perillyl alcohol with sensitization by pentoxifylline: increased BCL 2 and BAX protein expression. BAX addiction sensitization 17008791 In vitro induction of apoptosis in U937 cells by perillyl alcohol with sensitization by pentoxifylline: increased BCL 2 and BAX protein expression. BAX drug cannabinoid 15545023 Finally, cannabinoids might also be involved in the apoptotic death that occurs during brain development, possibly by influencing the expression of Bcl 2/Bax system. BAX drug opioid 15183518 In the core, neuronal apoptotic inhibitory protein (NAIP), GABA A alpha1 subunit, GRIN2C, GRIA1, mGluR1, D4 dopamine receptor and PSD 95 were upregulated by morphine administration whereas bax, bcl x, cox 1 and MAP2 were decreased. BAX drug alcohol 14502238 Ethanol induced neuronal apoptosis in vivo requires BAX in the developing mouse brain. BAX drug alcohol 14502238 We also found that ethanol triggers robust caspase 3 activation and apoptotic neurodegeneration in C57BL/6 wildtype mice, but induces neither phenomenon in homozygous Bax deficient mice. BAX drug alcohol 14502238 Therefore, it appears that ethanol induced neuroapoptosis is an intrinsic pathway mediated phenomenon involving Bax induced disruption of mitochondrial membranes and cytochrome c release as early events leading to caspase 3 activation. BAX drug alcohol 12603597 Ethanol decreased Jurkat cell expression of Bcl 2, whereas ethanol increased Jurkat cell expression of Bax.

BAX addiction intoxication 12043192 To characterize the biochemical mechanism of cell death induced by ethanol intoxication, we examined expression of mRNAs of bcl 2 and bax genes in the brain, which are related to apoptosis, by using the reverse transcription polymerase chain reaction method (RT PCR). BAX drug alcohol 12043192 We found that bcl 2 or bax mRNA expressions in the brain were changed after short term ethanol exposure. BAX drug alcohol 12043192 These results suggest that bcl 2 or bax may have functional significance about ethanol intoxication. BAX addiction intoxication 12043192 These results suggest that bcl 2 or bax may have functional significance about ethanol intoxication. BAX addiction withdrawal 10602513 Regardless of the steady state of the Bax protein, we found that in both K562 and K562 Tat cells, this protein is located in the nucleus, but after serum withdrawal its localization was mainly in the cytoplasm. BAX drug opioid 10534122 Morphine treated Jurkat cells also showed a decreased expression of bcl 2 and an enhanced expression of bax. BAX drug opioid 9469450 Morphine promoted the synthesis of Bax and p53 proteins by Mphi. BAX drug opioid 9469450 The effector phase of morphine induced apoptosis appears to proceed through the accumulation of Bax and activation of ICE 1.

PPARA addiction intoxication 28882574 However, neither GdCl3 nor etanercept could affect binge drinking induced decrease of PPAR α, ACOX, FAS, ACC and SCD protein levels, or increase of the LC3 II/LC3 I ratio and p62 protein level. PPARA drug alcohol 28769774 Fenofibrate is a peroxisome proliferator activated receptor alpha (PPARα) agonist, which induces the proliferation of peroxisomes in the liver, leading to increases in catalase levels that result in acetaldehyde accumulation at aversive levels in the blood when animals consume ethanol.

PPARA drug opioid 27255640 We have previously demonstrated that peripheral administration of 15d PGJ2 in the Temporomandibular joint (TMJ) of rats can prevent nociceptor sensitization, mediated by peroxisome proliferator activated receptor γ (PPAR γ), and κ and δ opioid receptors. PPARA addiction sensitization 27255640 We have previously demonstrated that peripheral administration of 15d PGJ2 in the Temporomandibular joint (TMJ) of rats can prevent nociceptor sensitization, mediated by peroxisome proliferator activated receptor γ (PPAR γ), and κ and δ opioid receptors. PPARA drug opioid 27255640 However, the mechanism that underlies the signaling of PPAR γ (upon activation by 15d PGJ2) to induce antinociception, and how the opioid receptors are activated via 15d PGJ2 are not fully understood. PPARA drug opioid 27255640 Once activated by 15d PGJ2, PPAR γ induces the release of β endorphin and dynorphin, which activates κ and δ opioid receptors in primary sensory neurons to induce the antinociceptive effect. PPARA drug nicotine 26864774 FAAH inhibition has been recently identified as having a critical involvement in behaviors related to nicotine addiction and has been shown to reduce the effect of nicotine on the mesolimbic dopaminergic system via CB1R and peroxisome proliferator activated receptor alpha (PPARα).

PPARA drug alcohol 26857685 Several peroxisome proliferator activated receptor (PPAR) agonists reduce voluntary alcohol consumption in rodent models, and evidence suggests that PPARα and γ subunits play an important role in this effect. PPARA drug alcohol 26857541 In the accompanying article, we showed that activation of peroxisome proliferator activated receptor alpha (PPARα) signaling by fenofibrate and tesaglitazar decreases ethanol (EtOH) consumption in mice. PPARA drug alcohol 26857541 These studies indicate the complexity of EtOH dependent and EtOH independent behaviors that are altered by PPAR agonists and provide evidence for novel behavioral actions of these drugs that may contribute to PPAR mediated effects on alcohol drinking.

WARS1 addiction relapse 23129288 In a convenience sample of 157 U.S. service members from the Afghanistan and Iraq wars seeking health care services at a Veterans Administration (VA) hospital, this study examined (a) the impact of attachment characteristics on several key mental health symptoms in this new generation of veterans, (b) the relative frequencies of prominent attachment styles in the sample, and (c) how these higher order orientations related to study outcomes.

WARS1 drug alcohol 18698065 High rates of alcohol misuse after deployment have been reported among personnel returning from past conflicts, yet investigations of alcohol misuse after return from the current wars in Iraq and Afghanistan are lacking. WARS1 addiction intoxication 17989301 A cross linking assay and Western blot analysis of microdissected CA1 area of hippocampal slices obtained 1 h after EtOH intoxication (5 g/kg, gavage), revealed decreases in the cell surface fraction of alpha4 and delta, but not alpha1, alpha5, or gamma2 GABA(A)R subunits, without changes in their total content.

WARS1 drug alcohol 15542698 PCR based assays showed that alcoholism was associated with polymorphisms of the dopamine D2 receptor (DRD2) TaqI B (P = .029) and the GABAA beta2 subunit C1412T (P = .012) genes, but not with the glutamate receptor subunit gene NMDAR2B (366C/G), the serotonin transporter gene (5HTTL PR), the dopamine transporter gene DAT1(SLC6A3), the dopamine D2 receptor gene DRD2 TaqI A, or the GABAA alpha1(A15G), alpha6(T1519C), and gamma2(G3145A) subunit genes. WARS1 drug alcohol 14751585 The role of the alpha6 subunit gene cluster in the ethanol non preferring phenotype was here investigated by measuring the levels of alpha1, alpha6 and gamma2 peptide in the cerebellum of normal (RR) and mutated (QQ) sNP rats after 2 weeks of chronic ethanol administration. WARS1 drug alcohol 14751585 Interestingly, chronic ethanol administration decreased alpha1 peptide levels in the cerebellum of both rat lines to a similar extent (30.99%+/ 6.74 and 27.12%+/ 9.83 in RR and QQ rats, respectively), while gamma2 peptide levels remained unchanged. WARS1 drug benzodiazepine 14572465 Deletion of the gamma2 subunit in the third postnatal week resulted in loss of benzodiazepine binding sites and parallel loss of punctate immunoreactivity for postsynaptic GABA(A) receptors and gephyrin. WARS1 addiction reward 14572465 Thus, the gamma2 subunit contributes to postsynaptic localization of GABA(A) receptors and gephyrin by a mechanism that is operant in mature neurons and not limited to immature neurons, most likely through interaction with proteins involved in trafficking of synaptic GABA(A) receptors.

WARS1 drug alcohol 12591165 Recent preclinical and clinical studies have indicated a possible involvement of the genes encoding for the GABA(A) receptor subunits alpha6, beta2, alpha1 and gamma2 in the genetic susceptibility to alcohol abuse. WARS1 drug alcohol 12591165 In the present study the molecular composition of other GABA(A) subunits (beta2, alpha1 and gamma2) were analyzed in order to further investigate the involvement of the GABA(A) receptors in the genetic predisposition to voluntary alcohol intake. WARS1 drug alcohol 12591165 These results sustain the synteny for these clusters between the rodent and human genomes, and suggest that mutated GABA(A) beta2, alpha6, alpha1 and gamma2 subunit genes might contribute to the expression of an ethanol nonpreferring phenotype in a rat line that voluntarily avoids alcoholic solutions. WARS1 drug benzodiazepine 12488536 Immunoblotting revealed decrease in alpha1 and delta expression and increase in gamma2 and alpha4 subunits in hippocampus of CIE rats, confirmed by an increase in diazepam insensitive binding for ethyl 8 azido 5,6 dihydro 5 methyl 6 oxo 4H imidazo(1,5 alpha)(1,4)benzodiazepine 3 carboxylate (Ro15 4513).

WARS1 drug alcohol 10947837 We conclude that acute functional tolerance to ethanol is very sensitive to the amount of GABAA receptor gamma2 subunit available (regardless of whether it is gamma2L or gamma2S) but overexpression of neither subunit isoform alters other behavioural and biochemical phenotypes.

WARS1 drug benzodiazepine 9586850 While GABA enhancement of benzodiazepine binding was reduced in the nucleus accumbens after repeated diazepam treatment, there was little evidence to support adaptive changes in GABA(A) receptors or GABA(A) subunit gene expression (gamma2, alpha1, or alpha4) as underlying the functional changes in the identified circuits. WARS1 drug cannabinoid 9515986 The major results are that most Americans rely on the mass media for information about the scope of the drug abuse problem; Americans do not think that the Wars on Drugs have succeeded, but they do not want to quit on these efforts; weak support exists for increasing funding for drug treatment; support for preventive education has increased during the 1990s; criminal justice responses remain very popular; for many, illicit drug use is a moral rather than a public health issue; the public supports allowing physicians to prescribe marijuana for severe illness, but opposes the general legalization of marijuana and other illicit drugs; and needle exchange programs are supported by a bare majority, but only when they are told that the American Medical Association supports these programs.

ADH1C drug alcohol 20617019 A new view of alcohol metabolism and alcoholism role of the high Km Class III alcohol dehydrogenase (ADH3). ADH1C drug alcohol 20617019 Recently, using ADH3 null mutant mice, we demonstrated that ADH3 (Class III), which has a high K(m) and is a ubiquitous enzyme of ancient origin, contributes to systemic alcohol metabolism in a dose dependent manner, thereby diminishing acute alcohol intoxication. ADH1C addiction intoxication 20617019 Recently, using ADH3 null mutant mice, we demonstrated that ADH3 (Class III), which has a high K(m) and is a ubiquitous enzyme of ancient origin, contributes to systemic alcohol metabolism in a dose dependent manner, thereby diminishing acute alcohol intoxication. ADH1C drug alcohol 20617019 Although the activity of ADH3 toward ethanol is usually low in vitro due to its very high K(m), the catalytic efficiency (k(cat)/K(m)) is markedly enhanced when the solution hydrophobicity of the reaction medium increases. ADH1C drug alcohol 20617019 When various doses of ethanol are administered to mice, liver ADH3 activity is dynamically regulated through induction or kinetic activation, while ADH1 activity is markedly lower at high doses (3 5 g/kg). ADH1C drug alcohol 20617019 These data suggest that ADH3 plays a dynamic role in alcohol metabolism, either collaborating with ADH1 or compensating for the reduced role of ADH1. ADH1C drug alcohol 20617019 A complex two ADH model that ascribes total liver ADH activity to both ADH1 and ADH3 explains the dose dependent changes in the pharmacokinetic parameters (beta, CL(T), AUC) of blood ethanol very well, suggesting that alcohol metabolism in mice is primarily governed by these two ADHs. ADH1C drug alcohol 20617019 In patients with alcoholic liver disease, liver ADH3 activity increases, while ADH1 activity decreases, as alcohol intake increases. ADH1C drug alcohol 20617019 These data suggest that chronic binge drinking and the resulting liver disease shifts the key enzyme in alcohol metabolism from low K(m) ADH1 to high K(m) ADH3, thereby reducing the rate of alcohol metabolism. ADH1C addiction intoxication 20617019 These data suggest that chronic binge drinking and the resulting liver disease shifts the key enzyme in alcohol metabolism from low K(m) ADH1 to high K(m) ADH3, thereby reducing the rate of alcohol metabolism. ADH1C drug alcohol 20617019 The interdependent increase in the ADH3/ADH1 activity ratio and AUC may be a factor in the development of alcoholic liver disease. ADH1C drug alcohol 20617019 However, the adaptive increase in ADH3 sustains alcohol metabolism, even in patients with alcoholic liver cirrhosis, which makes it possible for them to drink themselves to death. ADH1C drug alcohol 20617019 Thus, the regulation of ADH3 activity may be important in preventing alcoholism development.

ADH1C addiction intoxication 19489444 Recently, we used ADH3 null mutant mice to demonstrate that high Km ADH3 (Class III), a ubiquitous enzyme of ancient origin, contributes to systemic alcohol metabolism dose dependently resulting in a diminution of acute alcohol intoxication. ADH1C drug alcohol 19489444 Although the ethanol activity of ADH3 in vitro is usually low due to its very high Km, the catalytic efficiency (k(cat)/Km) was markedly enhanced when the solution hydrophobicity of the reaction medium was increased. ADH1C drug alcohol 19489444 By acute administrations of ethanol to mice at various doses, liver ADH3 activity was dynamically regulated through induction or kinetic activation, though ADH1 activity was markedly decreased at higher doses (3 5 g/kg). ADH1C drug alcohol 19489444 These data suggest that ADH3 plays a dynamical share in alcohol metabolism with ADH1, collaborating with it or supplementing the decreased role of ADH1. ADH1C drug alcohol 19489444 The two ADH complex model, which ascribes total liver ADH activity to both ADH1 and ADH3, explained well the dose dependent changes in pharmacokinetic parameters (beta, CL(T), AUC) of blood ethanol, suggesting that alcohol metabolism in mice is primarily governed by the two ADHs. ADH1C drug alcohol 19489444 In patients with alcoholic liver diseases, the liver ADH3 activity increased but the ADH1 activity decreased with an increase in alcohol intake. ADH1C drug alcohol 19489444 These data suggest that heavy and chronic drinking shifts the main enzyme in alcohol metabolism from low Km ADH1 to high Km ADH3 to develop alcoholic liver diseases by the nonlinear increase in AUC due to the decrease of the metabolic rate. ADH1C drug alcohol 19489444 However, the adaptively increased ADH3 keeps the ability of alcohol metabolism even in patients with alcoholic liver cirrhosis and make possible for them to keep drinking to death. ADH1C drug alcohol 19489444 Therefore, the regulation of ADH3 activity may be important to prevent the development of alcoholism. ADH1C drug alcohol 18996923 After controlling for rs1229984, an independent association was observed between rs1042026 (ADH1B) and alcohol intake (P=4.7 x 10( 5)) and suggestive associations (P<0.001) between alcohol consumption phenotypes and rs1693482 (ADH1C), rs1230165 (ADH5) and rs3762894 (ADH4). ADH1C drug alcohol 17885622 The subjects were divided into 3 combinatorial genotypic groups of alcohol dehydrogenase (ADH) and ALDH, that is, ALDH2*1/*1 ADH1B*1/*1 ADH1C*1/*1 (n=8), ALDH2*1/*1 ADH1B*2/*2 ADH1C*1/*1 (n=8), and ALDH2*1/*2 ADH1B*2/*2 ADH1C*1/*1 (n=16). ADH1C drug alcohol 17718398 Studies have demonstrated that a certain variant of the gene encoding ADH1B (ADH1B*3) is associated with a reduced risk of alcoholism in Afro Trinidadians, as is a variant of the gene encoding ADH1C (i.e., ADH1C*1) in Indo Trinidadians. ADH1C drug alcohol 17718397 Variants of three genes encoding alcohol metabolizing enzymes, the aldehyde dehydrogenase gene ALDH2 and the alcohol dehydrogenase genes ADH1B and ADH1C, have been associated with reduced rates of alcohol dependence. ADH1C addiction dependence 17718397 Variants of three genes encoding alcohol metabolizing enzymes, the aldehyde dehydrogenase gene ALDH2 and the alcohol dehydrogenase genes ADH1B and ADH1C, have been associated with reduced rates of alcohol dependence. ADH1C drug alcohol 17629074 The aim of the present study was to find in the Polish population the ADH3 genotypes, which are likely to be responsible for higher susceptibility to alcohol disease of the liver and chronic alcohol pancreatitis. ADH1C drug alcohol 17629074 The genotype ADH3*1/ADH3*1 was found to be significantly more frequent in alcohol abusers compared to non drinkers. ADH1C drug alcohol 17629074 The examinations of the group of alcohol abusers showed that the genotype ADH3*2/ADH3*2 occurred statistically significantly less frequently in patients with chronic pancreatitis than those without alimentary lesions and patients with cirrhosis. ADH1C drug alcohol 17454860 We determined the allele and genotype of ADH2, ADH3 and ALDH2 in 198 subjects: 57 with alcohol cirrhosis, 44 with alcohol chronic pancreatitis and 43 "healthy alcoholics"; 54 healthy non drinkers served as controls. ADH1C drug alcohol 17454860 The ADH2*1 and the ADH3*1 alleles were statistically more common among patients who abuse alcohol in comparison with the controls. ADH1C drug alcohol 17454860 The ADH2*1/*1 and the ADH3*1/*1 genotypes were statistically significantly more common among the patients who abuse alcohol than in the control group. ADH1C drug alcohol 17454860 Patients with the ADH3*1 allele and the ADH3*1/*1 genotype started to abuse alcohol significantly earlier in comparison to the patients with the ADH3*2 allele and the ADH3*2 /*2 genotype. ADH1C drug alcohol 17454860 In the Polish population examined, the ADH3*1 allele and the ADH3*1/*1 genotype are conducive to the development of alcoholism, alcohol liver cirrhosis and alcohol chronic pancreatitis. ADH1C drug alcohol 17454860 The ADH3*1 allele and the ADH3*1/*1 genotype are conducive to alcohol abuse starting at a younger age. ADH1C drug alcohol 17250612 Two of the class I alcohol dehydrogenase (ADH) genes located on chromosome 4 (ADH1B and ADH1C) encode for multiple isozymes that differ in their kinetic properties.

ADH1C addiction dependence 17134660 ADH1C*2 allele is associated with alcohol dependence and elevated liver enzymes in Trinidad and Tobago. ADH1C drug alcohol 17134660 This study sought to determine whether an association exists between ADH (ADH1C previously ADH3, ADH1B*2 previously ADH2*2) genotypes, alcohol dependence, drinking history, and liver function tests in the two major ethnic groups of Trinidad and Tobago (TT).

ADH1C drug alcohol 17134660 The ADH1C*2 allele was significantly associated with alcohol dependence overall and within Indo TT ancestry, however, it was not associated with current or heaviest alcohol consumption levels. ADH1C addiction dependence 17134660 The ADH1C*2 allele was significantly associated with alcohol dependence overall and within Indo TT ancestry, however, it was not associated with current or heaviest alcohol consumption levels. ADH1C drug alcohol 17134660 Additionally, GGT levels were also found to be elevated (P<.02) within Indo TT alcohol dependents with at least one ADH1C*2 allele but not within the Afro TT alcohol dependents with that allele. ADH1C drug alcohol 17134660 A linear regression that included alcohol dependence and levels of alcohol consumption confirmed that levels of serum GGT were significantly associated with the ADH1C*2 genotype. ADH1C addiction dependence 17134660 A linear regression that included alcohol dependence and levels of alcohol consumption confirmed that levels of serum GGT were significantly associated with the ADH1C*2 genotype. ADH1C drug alcohol 17134660 These results suggest that ADH1C polymorphisms are associated with alcohol dependence and alcohol associated elevations of liver enzymes in a population with a low frequency of ADH1B2 alleles. ADH1C addiction dependence 17134660 These results suggest that ADH1C polymorphisms are associated with alcohol dependence and alcohol associated elevations of liver enzymes in a population with a low frequency of ADH1B2 alleles. ADH1C drug alcohol 16930209 Variations in the ADH1B and ADH1C genes may influence the LR to alcohol by increasing levels of acetaldehyde during alcohol metabolism, although most data on this question come from Asian populations. ADH1C drug alcohol 16431092 In vivo contribution of Class III alcohol dehydrogenase (ADH3) to alcohol metabolism through activation by cytoplasmic solution hydrophobicity. ADH1C drug alcohol 16431092 In this study, we used Adh3 null mutant mice to demonstrate that Class III ADH (ADH3), a ubiquitous enzyme of ancient origin, contributes to alcohol metabolism in vivo dose dependently resulting in a diminution of acute alcohol intoxication. ADH1C addiction intoxication 16431092 In this study, we used Adh3 null mutant mice to demonstrate that Class III ADH (ADH3), a ubiquitous enzyme of ancient origin, contributes to alcohol metabolism in vivo dose dependently resulting in a diminution of acute alcohol intoxication. ADH1C drug alcohol 16431092 Although the ethanol oxidation activity of ADH3 in vitro is low due to its very high Km, it was found to exhibit a markedly enhanced catalytic efficiency (kcat/Km) toward ethanol when the solution hydrophobicity of the reaction medium was increased with a hydrophobic substance. ADH1C drug alcohol 16431092 So, the in vivo contribution of high Km ADH3 to alcohol metabolism is likely to involve activation in a hydrophobic solution. ADH1C drug alcohol 16431092 Thus, the present study demonstrated that ADH3 plays an important role in systemic ethanol metabolism at higher levels of blood ethanol through activation by cytoplasmic solution hydrophobicity.

ADH1C drug alcohol 16404797 Studies of the ADHIBand ADH1C haplotypes, however, have shown that ADH1C*I is in linkage disequilibrium with ADHiB*2, and the ADH1C*i allele does not appear to have significant unique associations with alcohol dependence.

ADH1C drug alcohol 16184481 Genetic time series analysis identifies a major QTL for in vivo alcohol metabolism not predicted by in vitro studies of structural protein polymorphism at the ADH1B or ADH1C loci. ADH1C drug alcohol 15863807 The authors examined the genetic polymorphisms of alcohol dehydrogenase 2 and 3 (ADH2 and ADH3) and aldehyde dehydrogenase (ALDH2) in patients diagnosed as having Cloninger's type I or type II alcoholism. ADH1C drug alcohol 15863807 Seventy two alcoholic men and 38 nonalcoholic, healthy men were tested for the distribution of genotypes and alleles of ADH2, ADH3, and ALDH2. ADH1C drug alcohol 15863807 The frequencies of ADH2*1 and ADH3*2 alleles were significantly higher in men with type II alcoholism than in men with type I alcoholism and healthy men. ADH1C drug alcohol 15542698 The genotype for the most active alcohol dehydrogenase enzyme ADH1C was associated with a lower risk of alcoholism (P = .026) and was less prevalent in alcoholics with DRD2TaqIA2/A2 (P = .047), GABAA beta2 1412C/C (P = .01), or EAAT2 603G/A (P = .022) genotypes.

ADH1C drug alcohol 12750236 Alcohol is a probable risk factor with regard to colorectal neoplasm and is metabolized to the carcinogen acetaldehyde by the genetically polymorphic alcohol dehydrogenase 3 (ADH3) enzyme. ADH1C drug alcohol 12750236 We evaluated whether the association between alcohol and colorectal adenomas is modified by ADH3 polymorphism. ADH1C drug alcohol 12750236 Among subjects in the highest tertile of alcohol consumption, those with the ADH3*1/*1 genotype were at higher risk (OR, 1.8; 95% CI, 1.0 3.1) than those with other ADH3 genotypes (OR, 1.2; 95% CI, 0.7 1.9) when compared with those in the lowest tertile with ADH3*1/*2 or ADH3*2/*2 genotypes. ADH1C drug alcohol 12750236 ADH3 polymorphism may modify the association between alcohol consumption and colorectal adenomas. ADH1C drug alcohol 12710951 The ADH3*2 and CYP2E1 c2 alleles increase the risk of alcoholism in Mexican American men. ADH1C drug alcohol 12710951 To identify the association between the polymorphisms of genes encoding alcohol metabolizing enzymes and alcoholism, the alcohol dehydrogenase 2 (ADH2), alcohol dehydrogenase 3 (ADH3), aldehyde dehydrogenase 2 (ALDH2), and cytochrome P450 2E1 (CYP2E1) genes were studied in 101 male Mexican American alcoholics. ADH1C drug alcohol 12710951 A strong association was found between ADH3 genotype and alcoholism; the percentage of subjects who carry the ADH3*2 allele was significantly higher in alcoholics (64.4%) than controls (50%). ADH1C drug alcohol 12710951 Among 101 alcoholics, only 18 subjects carry neither ADH3*2 nor CYP2E1 c2 alleles. ADH1C drug alcohol 12710951 Taken together, ADH3*2 and CYP2E1 c2/C alleles might independently contribute to the development of alcoholism in Mexican American men.

ADH1C drug alcohol 11752857 Alcohol dehydrogenase type 3 (ADH3) and the risk of bladder cancer. ADH1C drug alcohol 11752857 After correction for sex, age and smoking, ORs for ADH3 genotype and alcohol intake were 2.10 (1.05 4.22) and 1.21 (0.60 2.44), respectively. ADH1C drug nicotine 11752857 After correction for sex, age and smoking, ORs for ADH3 genotype and alcohol intake were 2.10 (1.05 4.22) and 1.21 (0.60 2.44), respectively. ADH1C drug alcohol 11752857 Although moderate drinkers with the gamma1gamma1 genotype seem to have the highest risk, we did not get a clear indication that ADH3 genotype modifies the relationship between alcohol intake and bladder cancer. ADH1C drug alcohol 11584143 In view of this association and the known genetic influences on both alcohol pharmacokinetics and alcohol dependence, it is probable that part of the heritability of dependence is mediated by genes (other than the known ADH2 and ADH3 polymorphisms) affecting alcohol metabolism. ADH1C addiction dependence 11584143 In view of this association and the known genetic influences on both alcohol pharmacokinetics and alcohol dependence, it is probable that part of the heritability of dependence is mediated by genes (other than the known ADH2 and ADH3 polymorphisms) affecting alcohol metabolism. ADH1C drug alcohol 10630602 An alcohol dependent patient was identified to be ALDH2*2/*2, ADH2*2/*2, and ADH3*1/*2. ADH1C drug alcohol 10597438 Evidence for linkage to the ALDX1 alcoholism phenotype at the ADH3 functional candidate gene was increased in the late onset subgroup (Bonferroni corrected significance level < 0.002), as compared with the unstratified sample that replicated COGA linkage obtained in the same analysis; there was no evidence for linkage at this locus in the early onset subgroup. ADH1C drug alcohol 10597410 For the "alcoholism free" outcome, we found significant linkage signals at D4S2457, D41651 (both flank ADH3), D11S2359, and D16S47 and significant linkage disequilibrium signals at D4S2361, FABP2, D11S2359, D19S431 and D19S47 D19S198 D19S601. ADH1C drug alcohol 10235293 The different genotypes at the genes encoding the enzymes involved in alcohol metabolism, class one alcohol dehydrogenase (ADH2 and ADH3) and mitochondrial aldehyde dehydrogenase (ALDH2), have previously been shown to confer different predispositions to the development of alcoholism in Chinese Han males (Thomasson et al., 1991; Chen WJ et al., 1996; Chen CC et al., unpublished data). ADH1C drug alcohol 10235293 Therefore, association studies of alcoholism in Chinese Han might be more sensitive if controlled for the genotypes of ADH2,ADH3, and ALDH2, when other loci, such as DRD2, are examined. ADH1C drug alcohol 10235293 These tests included considering the high risk (ADH2*1/*1; *1/*2; ADH3*1/*2; *2/*2; and ALDH2*1/*1) and the low risk (ADH2*2/*2; ADH3*1/*1; and ALDH2*1/*2; *2/*2) groups of alcoholics, as well as nonalcoholic controls. ADH1C drug alcohol 10235293 After stratification by the relevant genotypes of ADH2, ADH3, and ALDH2 no significant association exists between the genetic variants at the DRD2 locus and alcoholism in the Chinese Han population. ADH1C drug alcohol 9731720 Caucasians are polymorphic at only two of these gene loci cytochrome P450 2E1 (CYP2E1) and alcohol dehydrogenase 3 (ADH3). ADH1C drug alcohol 9731720 We examined the frequency of the RsaI polymorphism of CYP2E1 and ADH3 genotype in 264 patients with alcoholic liver disease and 121 local control individuals. ADH1C drug alcohol 9731720 This risk appears to be particularly manifest in individuals carrying the ADH3*2 allele, presumably reflecting increased metabolism of ethanol by CYP2E1. ADH1C drug alcohol 9731720 In the absence of the c2 allele, ADH3 genotype does not influence the risk of advanced alcoholic liver disease but, in males at least, may influence the risk of alcoholism. ADH1C drug alcohol 9373704 The purpose of this paper is to assemble and evaluate existing data on the effect of genetic variation in ADH2 and ADH3 on the risk of alcohol dependence, and on the risk of alcoholic liver disease.

ADH1C drug alcohol 9373704 ADH3 variation also has significant effects on alcohol dependence, which may be due to linkage to ADH2; the ADH3 effect differs significantly between Asian and European subjects. ADH1C addiction dependence 9373704 ADH3 variation also has significant effects on alcohol dependence, which may be due to linkage to ADH2; the ADH3 effect differs significantly between Asian and European subjects. ADH1C drug alcohol 9066994 In this report we determined the genotypes for three genes, ADH2, ADH3, and ALDH2 among subjects with alcohol dependence (n = 159) and ethnically matched normal controls (n = 149) for the four largest aboriginal groups (Atayal, Ami, Bunun, and Paiwan) in Taiwan.

ADH1C drug nicotine 8904964 The influences of estimated body water, recent drinking history, recent smoking history, polymorphism at the ADH2 and ADH3 loci, family history of alcoholism, and percentage Native American heritage on alcohol elimination rate were determined using multiple regression analyses. ADH1C drug alcohol 8773821 Alcohol metabolising genes and alcoholism among Taiwanese Han men: independent effect of ADH2, ADH3 and ALDH2. ADH1C drug alcohol 8773821 The association of ALDH2 and ADH2 with the development of alcoholism was found to be independent of each other and has been replicated in different Asian populations, while the effect of ADH3 is less studied. ADH1C drug alcohol 8773821 Multiple logistic regression was then applied to assess the contribution of ADH3 to alcoholism by controlling the effect of ALDH2 and ADH2. ADH1C drug alcohol 8773821 The results of multivariate analyses demonstrated that the odds ratios for an increment of one allele of ADH2*1, ADH3*2 and ALDH2*1 in the development of alcoholism were 4.18, 3.82, and 6.89, respectively. ADH1C drug alcohol 8651462 A comparison of the genotypes of ALDH2, ADH2, ADH3, and cytochrome P 4502E1 between alcoholics and nonalcoholics. ADH1C drug alcohol 8651462 We examined the genotypes of the aldehyde dehydrogenase (ALDH) 2, alcohol dehydrogenase (ADH) 2, ADH3, and P 4502E1 loci of 53 alcoholics and 97 nonalcoholics. ADH1C drug alcohol 8651462 Our study revealed differences in the allelic frequencies of the ALDH2, ADH2, and ADH3 loci between alcoholics and nonalcoholics. ADH1C drug alcohol 8651462 For alcoholics with both homozygous ALDH2*1/1 and heterozygous ALDH2*1/2 genotypes, it was found that ADH2 and ADH3 played important rates. ADH1C drug alcohol 7943668 Genetic variation at two polymorphic alcohol dehydrogenase loci, ADH2 and ADH3, and at the polymorphic mitochondrial aldehyde dehydrogenase locus, ALDH2, may influence the risk of developing alcoholism by modulating the rate of elimination of ethanol and the rate of formation and elimination of acetaldehyde.

ACHE drug nicotine 30712397 Nicotine and the AChE inhibitors donepezil and galantamine dose dependently increased responding on the nicotine appropriate lever with ED50 values of 0.35, 0.22, and 0.77 mg/kg, respectively. ACHE drug nicotine 30712397 Oxotremorine, a muscarinic acetylcholine receptor agonist that was used to explore the extent to which muscarinic receptor agonism might contribute to the effects of AChE inhibitors, produced 94% nicotine lever responding (ED50 value 0.013 mg/kg). ACHE drug nicotine 30712397 Collectively, these results suggest that AChE inhibitors can mimic the effects of nicotine by indirectly stimulating both nicotinic and muscarinic receptors. ACHE drug nicotine 30712397 Inasmuch as some smoking cessation aids work by exerting nicotine like effects, the current results are consistent with the potential use of AChE inhibitors as novel smoking cessation aids. ACHE drug nicotine 30099467 In addition, curcuminoid significantly suppressed the priming effects of nicotine and inhibited acetylcholinesterase (AChE) activity.

ACHE drug nicotine 24854235 Following 14 days of nicotine exposure, the NAc was dissected and acetylcholinesterase (AChE) activity was compared across groups. ACHE drug nicotine 24854235 The second study revealed that nicotine exposure increased AChE activity in the NAc to a greater extent in adolescent versus adult rats. ACHE addiction intoxication 23959117 Acetylcholinesterase (AChE) reactivators were developed for the treatment of organophosphate intoxication. ACHE drug benzodiazepine 23959117 Standard care involves the use of anticonvulsants (e.g., diazepam), parasympatolytics (e.g., atropine) and oximes that restore AChE activity.

ACHE drug alcohol 23797318 Results demonstrated that AChE activity increased in the Cd/ethanol group when compared to saline/ethanol group. ACHE drug alcohol 23797318 Treatment with quercetin prevented the increase in AChE activity when compared to Cd/ethanol group. ACHE drug opioid 23651795 Acetylcholinesterase (AChE) activity and [³H] epibatidine binding were evaluated in order to determine if morphine dependence and withdrawal induces alterations in cholinergic signaling or expression of high affinity nicotinic acetylcholine receptors (nAChRs) in the midbrain (MB), medial habenula (MHb) and interpeduncular nucleus (IPN). ACHE addiction dependence 23651795 Acetylcholinesterase (AChE) activity and [³H] epibatidine binding were evaluated in order to determine if morphine dependence and withdrawal induces alterations in cholinergic signaling or expression of high affinity nicotinic acetylcholine receptors (nAChRs) in the midbrain (MB), medial habenula (MHb) and interpeduncular nucleus (IPN).

ACHE drug amphetamine 23245536 The present study aims to investigate the effects of mood stabilizers, lithium (Li) and valproate (VPA), on acetylcholinesterase (AChE) activity in the brains of rats subjected to an animal model of mania induced by D amphetamine (D AMPH). ACHE drug amphetamine 23245536 However, D AMPH decreased activity of AChE in the striatum of rats in both the reversion and prevention treatments. ACHE addiction reward 23245536 Our findings further support the notion that the mechanisms of mood stabilizers also involve changes in AChE activity, thus reinforcing the need for more studies to better characterize the role of acetylcholine in bipolar disorder. ACHE drug psychedelics 22200647 The question of whether ibogaine inhibits acetylcholinesterase (AChE) is of pharmacological and toxicological significance. ACHE drug psychedelics 22200647 Ibogaine inhibited AChE with an IC(50) of 520±40 μM. ACHE drug psychedelics 22200647 Ibogaine's inhibition of AChE is physiologically negligible, and does not appear to account for observations of functional effects in animals and humans that might otherwise suggest the possible involvement of pathways linked to muscarinic acetylcholine transmission. ACHE drug cocaine 22173266 This study was carried out to evaluate the effects of donepezil (which selectively inhibits AChE) and rivastigmine (which inhibits both AChE and butyrylcholinesterase) on cocaine self administration. ACHE drug benzodiazepine 21971501 Therapeutic treatment comprising of HI 6, atropine and diazepam has completely protected animals from death and reactivated soman inhibited AChE up to 40% in the plasma and RBC. ACHE addiction withdrawal 21633116 Effects on ChAT and AChE were dependent on the brain region and restricted to the withdrawal period: There were increased activities in the midbrain on PN30. ACHE drug nicotine 21116174 The purpose of this study was to investigate whether AChE Is with nicotinic acetylcholine receptor positive allosteric modulator properties generalize to the discriminative stimulus effect of nicotine in rats. ACHE drug nicotine 21116174 Our study showed that these three AChE Is partially generalized to the nicotine stimulus without a significant distinction between AChE Is with or without APL properties. ACHE drug benzodiazepine 20929049 Standard treatment for acute poisoning involves administration of intravenous atropine, oxime 2 PAM to counter AChE inhibition and diazepam for CNS protection. ACHE drug nicotine 20309727 The present study extends that finding by examining the effects of nicotine (Nic), Alc, and their combination on ChAT and acetylcholinesterase (AChE) in the frontal cortex and hippocampus of rat. ACHE drug cocaine 19836169 Because AChE inhibitors have been shown to decrease the reinforcing effects of cocaine in animals, our hypothesis was that pretreatment with donepezil would attenuate the perceived value and other positive subjective effects of cocaine.

ACHE drug alcohol 19576740 The ethyl acetate fraction of the alcohol extract (IC50 53.00 +/ 17.33microg/ml), and total alkaloid fraction (IC50 9.23+/ 6.08microg/ml) showed potential AChE inhibition. ACHE addiction intoxication 18784370 Management of this intoxication includes: (i) pretreatment with reversible blockers of AChE, (ii) blockade of muscarinic receptors with atropine, and (iii) facilitation of GABA(A) receptor signal transduction by benzodiazepines. ACHE drug nicotine 18776044 In summary, we found that nicotine acts as an anxiolytic in TgR mice but not in control mice and that continuously overexpressed AChE R regulates striatal gene expression, modulating cholinergic signaling and stress related pathways. ACHE addiction intoxication 18465647 Cholinergic drugs are currently in use, or in advanced stages of development, for the chronic treatment of Alzheimer's disease (AD) and myasthenia gravis, as well as for the treatment of acute intoxication with organophosphate or carbamate inhibitors of the ACh hydrolyzing enzyme acetyl cholinesterase (AChE).

ACHE drug alcohol 17888594 Here we investigated the in vitro and in vivo effects promoted by ethanol and its metabolites on zebrafish brain acetylcholinesterase (AChE). ACHE drug alcohol 17888594 There was a significant increase of AChE (33%) activity after acute 1% ethanol exposure. ACHE drug alcohol 17888594 However, ethanol in vitro did not alter AChE activity. ACHE drug alcohol 17888594 Furthermore, the acute ethanol exposure was able to inhibit AChE transcripts at 0.5% and 1%. ACHE drug alcohol 17888594 These findings suggest that the alterations on zebrafish AChE could reveal molecular mechanisms related to cholinergic signaling in alcoholism. ACHE addiction intoxication 17289099 In this study, we have evaluated donepezil hydrochloride, a partial reversible inhibitor of acetylcholinesterase (AChE) clinically used for treating Alzheimer's disease, in combination with procyclidine, used in treatment of Parkinson's disease and schizophrenia, as prophylaxis against intoxication by the nerve agent soman.

ACHE addiction addiction 12721372 Centrally active AChE inhibitors could thus be approached as novel and potential therapeutic agents for drug addiction. ACHE drug opioid 12185962 For example, anisodamine possesses good effects in the treatment of septic shock and morphine addiction; 3 n butylphthalide isolated from seeds of celery was shown to be a new cerebral anti ischemic agent; indirubin was identified as an anti leukemic drug with no inhibition of bone marrow; huperzine is a potent and reversible inhibitor of acetylcholinesterase (AChE) and its selective action is superior to that of donepezil; clausenamide was shown to be a potassium channel blocker, its nootropic effect was 50 100 times more potent than that of piracetam; bicyclol was synthesized from schizandrin C isolated from Fructus schizandrae.

ACHE drug opioid 10661498 In separate groups of rats, non toxic doses (50 and 250 microg/kg) of the acetylcholinesterase (AChE) inhibitor, diisopropylflurophosphate (DFP) were administered as single daily injections concomitant with the morphine infusion. ACHE addiction withdrawal 10661498 The apparent anti withdrawal effect of DFP was not reproduced by the selective peripherally acting AChE inhibitor, echothiophate, although both compounds effectively reduced the expression of certain other withdrawal symptoms. ACHE drug opioid 8149590 The effect of prenatal exposure to methadone via maternal osmotic minipumps on the expression of acetylcholinesterase (AChE) and choline acetyltransferase (ChAT) has been studied by light microscopy in the striatum of male and female rats. ACHE addiction intoxication 1631893 In a second experiment similarly treated marmosets were euthanized at 5 min (three saline treated animals) or at 10 min (three HI 6 treated animals) after the soman intoxication to enable the determination of acetylcholinesterase (AChE) activities in diaphragm and brain tissue. ACHE drug alcohol 1786855 Depending on the hydrophobicity and the site specificity of an inhibitor, striking differences were found in ethanol acetylcholinesterase (AChE) inhibitor interactions. ACHE drug alcohol 1786855 Their abilities to inhibit AChE activity were enhanced by ethanol. ACHE drug alcohol 1786855 Such an enhancement could not result from combining individual perturbations from ethanol and propidium or edrophonium, since ethanol itself increased the AChE activity. ACHE drug benzodiazepine 2364909 Diazepam (50 mg/kg, ip) slightly modified AchE and abolished hyperglycemia, hyperlactacidemia, and glycogenolytic effects. ACHE addiction sensitization 2474836 Iodide exerted a modest inhibition of photohemolysis and loss of AchE sensitized by E16, but had virtually no influence on sensitization by EYMA.

ACHE drug benzodiazepine 3004260 The effective dose range for physostigmine, 3 12 mumol/kg, is close to concentrations of this agent that inhibit activity in solubilized preparations of AChE from rabbit cortex, 1 3 X 10( 8) M. However, physostigmine, 10( 9) 10( 4) M, failed to displace 3H flunitrazepam from specific binding sites on membranes prepared from rabbit cerebral cortex. ACHE drug alcohol 6123169 Albino mongrel rats were used for the determination of the gamma glutamyl transferase (gamma GTF) and acetylcholine esterase (AChE) activities in various brain areas (cerebral hemispheres, cerebellum, hippocampus, brain stem) during acute (1.5; 4 and 6 g/kg i. p.) and chronic (15 months) alcoholic intoxication and alcohol withdrawal (24 48 h, 4 and 8 days).

ACHE drug alcohol 7198309 The activities of acetylcholinesterase (AChE) and choline acetyltransferase (ChaT) in the cerebral cortex, cerebellum, hypothalamus, hippocampus, midbrain and pons of adult, male mice injected with 2 g/kg ethanol and of control mice injected with physiological saline, were determined by spectrophotometric methods. ACHE drug alcohol 7198309 All animals were killed 30 min after injection between 11.00 h and 12.00 h. Results show that the acute dose of ethanol significantly decreased AChE activity only in the cerebral cortex whereas ChaT activity was reduced in the cerebral cortex, hypothalamus and hippocampus. ACHE drug alcohol 7198309 These findings show that the effect of an acute dose of ethanol on the cholinergic system of mouse brain is mediated through its effect on AChE and ChaT in specific regions. ACHE drug alcohol 7300947 This difference between fast and slow synapses was more pronounced after AChE inhibition or after ethanol treatment. ACHE drug nicotine 6156227 The content of acetylcholine (ACh) and activities of the cholinergic enzymes choline (acetyltransferase (CAT) and ACh esterase (AChE) were studied in intact and crushed rat sciatic nerve after chronic nicotine administration and withdrawal 2 days before the final experiment.

RTN4 drug opioid 31915860 Sixty seven male HAs performed a modified Go/NoGo task in which a motor response to frequent Go targets and no response to rare NoGo targets were required and a Go or NoGo target was displayed after either a heroin related or a neutral picture presented for the 200 ms and 600 ms SOAs. RTN4 drug alcohol 31866805 Alcohol use disorder (AUD) is characterized by increased impulsivity, which is multifactorial and can be assessed by tests like the delay discounting, Go Nogo, and stop signal task (SST). RTN4 drug alcohol 31864068 Following real and sham tDCS placing the anode over the right and cathode over the left DLPFC, a rewarded Go/NoGo paradigm was administrated to provoke behavioral biases (irrespective of the task goal) After the cognitive paradigm, alcohol consumption was examined using a beer taste test.

RTN4 addiction intoxication 31752082 Electrophysiological Correlates of an Alcohol Cued Go/NoGo Task: A Dual Process Approach to Binge Drinking in University Students. RTN4 drug alcohol 31752082 First year university students (n = 151, 54 % females) classified as binge drinkers (n = 71, ≥6 binge drinking episodes, defined as 5/7 standard drinks per occasion in the last 180 days) and controls (n = 80, <6 binge drinking episodes in the last 180 days) performed a beverage Go/NoGo task (pictures of alcoholic and nonalcoholic drinks were presented according to the condition as Go or NoGo stimuli; Go probability = 0.75) during event related potential recording. RTN4 addiction intoxication 31752082 First year university students (n = 151, 54 % females) classified as binge drinkers (n = 71, ≥6 binge drinking episodes, defined as 5/7 standard drinks per occasion in the last 180 days) and controls (n = 80, <6 binge drinking episodes in the last 180 days) performed a beverage Go/NoGo task (pictures of alcoholic and nonalcoholic drinks were presented according to the condition as Go or NoGo stimuli; Go probability = 0.75) during event related potential recording. RTN4 drug alcohol 31752082 In binge drinkers but not controls, the amplitude of the anterior N2 NoGo was larger in response to nonalcohol than in response to alcohol pictures. RTN4 addiction intoxication 31752082 In binge drinkers but not controls, the amplitude of the anterior N2 NoGo was larger in response to nonalcohol than in response to alcohol pictures. RTN4 drug alcohol 31611789 In experiment 1, we validated our experimental paradigm (electroencephalography combined with a modified Go/NoGo task using images of alcoholic and nonalcoholic drinks as prime stimuli) in 20 healthy adults to ensure that our protocol is suitable for assessing the behavioral and neural aspects of executive control. RTN4 drug nicotine 31474901 12 h Abstinence Induced ERP Changes in Young Smokers: Electrophysiological Evidence From a Go/NoGo Study. RTN4 drug nicotine 31474901 No significant changes were found in the number of NoGo errors and the response time of Go in young smokers after 12 h of abstinence. RTN4 drug alcohol 31277683 After baseline assessment, participants are randomly assigned to one of three computerized Go NoGo based inhibition training interventions (two alcohol specific versions with different Go/NoGo ratios, or neutral control training) and one of two intervention times (morning/afternoon), resulting in six study arms. RTN4 drug nicotine 31069895 In addition, greater commission errors on the Go/NoGo task were correlated with reduced neural response to smoking cues in the right dlPFC only among those with obesity. RTN4 drug alcohol 30376829 To test this, 108 participants (Mean age = 21.7, range = 16 27), whom were both drinkers and non drinkers performed a modified Go/NoGo task tailored to measure distraction and response inhibition in the presence of alcohol cues relative to neutral stimuli. RTN4 drug nicotine 29450255 In the current study, tobacco smokers (SMK; n = 22) and non smoking controls (CON; n = 19) completed a Go/NoGo task involving smoking cues during a functional magnetic resonance imaging (fMRI) scan. RTN4 drug nicotine 29450255 We evaluated pre cessation brain activity during NoGo trials in smokers who were versus were not able to quit smoking. RTN4 drug nicotine 29450255 However, compared to SMK who relapsed, SMK who attained biochemically validated abstinence at the end of the smoking cessation trial had greater neural activation in the anterior insula during NoGo trials specifically with smoking related cues. RTN4 drug nicotine 29402679 This study quantified the effects of age of smoking onset on response impulsivity and inhibitory control using a novel smoking Go/NoGo task (Luijten et al., 2011). RTN4 drug nicotine 29402679 Nicotine deprived adult EOS (n = 10) and LOS (n = 10) and adult healthy non smokers (HNS; n = 10) were shown smoking related and neutral images with either a blue (Go) or yellow (NoGo) frame. RTN4 drug nicotine 29402679 EOS also made more errors in inhibiting responses to smoking related (p ≤ 0.02) and neutral (p ≤ 0.02) NoGo trials. RTN4 drug nicotine 29402679 EOS exhibited greater difficulty than LOS in responding accurately to Go stimuli and withholding responses to both smoking and neutral NoGo stimuli, indicating greater response impulsivity, poor attention, and deficits in response inhibition. RTN4 drug nicotine 29370256 Immediately after this, they performed a smoking Go/NoGo task, while their brain activity was recorded. RTN4 drug nicotine 29193059 Male adolescent rats were trained on the Go/NoGo task, then subjected to nicotine CPP, and then randomly separated into four groups: sedentary (SED), high (HE), moderate (ME), and low intensity (LE) exercise. RTN4 addiction reward 29193059 Male adolescent rats were trained on the Go/NoGo task, then subjected to nicotine CPP, and then randomly separated into four groups: sedentary (SED), high (HE), moderate (ME), and low intensity (LE) exercise. RTN4 addiction reward 29193059 MEs and HEs showed higher performance accuracy on NoGo and lower scores on CPP tasks. RTN4 addiction reward 29193059 Expression of α7 nicotinic acetylcholine receptors (nAChRs) and downstream signaling molecules increased in MEs in prefrontal cortex but not hippocampus, with α7 nAChRs expression positively associated with NoGo accuracy and MWM probe test performance, but negatively correlated with CPP scores. RTN4 drug alcohol 29044574 All subjects performed a Go/NoGo task involving neutral and alcohol related NoGo trials, while their brain activity was recorded using multichannel electroencephalography. RTN4 drug alcohol 29044574 In subjects with strong craving, the conflict reflected in the NoGo N2 was enhanced in the alcohol related context. RTN4 addiction relapse 29044574 In subjects with strong craving, the conflict reflected in the NoGo N2 was enhanced in the alcohol related context. RTN4 drug nicotine 28826017 A smoking related background helps moderate smokers to focus: An event related potential study using a Go NoGo task. RTN4 drug nicotine 28826017 ERPs were recorded during a visual Go NoGo task performed by 18 smokers and 23 controls, in which either a frequent Go signal (letter "M") or a rare No Go signal ("letter W") were superimposed on three different long lasting background contexts: black neutral, smoking related and non smoking related. RTN4 drug nicotine 28826017 (1) Smokers performed worse and had an earlier NoGo N2 latency as compared to controls and independently of context, suggesting a general inhibition impairment; (2) with smoking related backgrounds specifically, smokers made fewer mistakes than they did in other contexts and displayed a larger NoGo P3 amplitude. RTN4 drug nicotine 28440102 Thirty two smokers (17 low dependent and 15 dependent; cut off FTND of 4) and 28 non smokers performed a modified Go/NoGo task using tobacco related words and neutral words as stimuli. RTN4 drug alcohol 28168896 Findings are congruent with event related oscillation studies showing reduced delta and/or theta oscillations in alcoholics during Go/NoGo tasks. RTN4 drug nicotine 27917562 The present study is the first to delineate functional networks of the anterior and posterior putamen in a Go NoGo response inhibition task, and to examine differences between smokers (n = 25) and non smokers (n = 23) within these networks. RTN4 drug cocaine 26037156 Compared with a placebo, cocaine yielded improved accuracy, quicker reaction times and an increased prefrontal NoGo P3 ERP. RTN4 drug cannabinoid 26037156 Cannabis produced opposing results; slower reaction times, impaired accuracy and a reduction in the amplitude of the prefrontal NoGo P3. RTN4 drug alcohol 27410426 Future studies may adapt the auditory Go/NoGo paradigm with specific acoustic stimuli (e.g., sound of opening a bottle) in order to address cognitive biases in particular disorders (e.g., alcohol dependence).

RTN4 drug nicotine 27277662 Seventy two smokers viewed smoking and neutral pictures and performed a Go NoGo and an Eriksen Flanker task, while ERPs were measured using electroencephalography. RTN4 drug alcohol 27000120 Thirty recently detoxified patients with alcohol addiction, and 31 healthy control subjects, were assessed in a Go and a NoGo condition, each using three visual stimuli: tea, juice and beer. RTN4 addiction addiction 27000120 Thirty recently detoxified patients with alcohol addiction, and 31 healthy control subjects, were assessed in a Go and a NoGo condition, each using three visual stimuli: tea, juice and beer. RTN4 drug alcohol 27000120 Additionally, patients' heightened N170 amplitudes in response to the alcohol related (beer) stimulus were found only under the NoGo condition, where subjects had to react to the frequent tea stimulus and ignore the beer and the juice stimuli, thus resulting in a condition x stimulus x group interaction. RTN4 drug alcohol 27000120 Patients reporting relapse in a 3 month follow up assessment showed larger NoGo N170 alcohol cue related ERP amplitudes and increased depression scores as compared to patients who stayed abstinent. RTN4 addiction relapse 27000120 Patients reporting relapse in a 3 month follow up assessment showed larger NoGo N170 alcohol cue related ERP amplitudes and increased depression scores as compared to patients who stayed abstinent. RTN4 drug opioid 26625401 As a case study, the method was applied to electroencephalography (EEG) data collected during a GO/NOGO cognitive task performed by untreated opiate addicts, those undergoing methadone maintenance treatment (MMT) for opiate dependence and a healthy control group. RTN4 addiction dependence 26625401 As a case study, the method was applied to electroencephalography (EEG) data collected during a GO/NOGO cognitive task performed by untreated opiate addicts, those undergoing methadone maintenance treatment (MMT) for opiate dependence and a healthy control group. RTN4 drug nicotine 26528200 A number of studies involving the use of Go/NoGo and stop signal paradigms have shown that smokers have reduced response inhibition for cigarette related cues. RTN4 drug nicotine 26093534 Inhibition control impairments in adolescent smokers: electrophysiological evidence from a Go/NoGo study. RTN4 drug nicotine 26093534 By using relatively homogenous groups of adolescent smokers (n = 18) and matched nonsmokers (n = 18), we employed event related potentials (ERP) to investigate the N200 and P300 amplitude and latency differences during a Go/NoGo task between the adolescent smokers and nonsmokers. RTN4 drug nicotine 26093534 Relative to nonsmokers, more NoGo response errors, reduced NoGo P300 amplitude, and longer P300 latency were observed in adolescent smokers. RTN4 drug nicotine 26093534 Correlation analysis revealed that the NoGo P300 amplitudes were significantly correlated with NoGo errors in both adolescent smokers and nonsmokers. RTN4 drug opioid 28911381 In order to investigate the response inhibition functions in heroin addicts who were treated with methadone maintenance, electroencephalography (EEG) was used to examine 14 heroin addicts treated with methadone maintenance (HDM), 17 heroin addicts (HD), and 18 healthy controls (HC) in an equiprobability Go∖NoGo task. RTN4 addiction aversion 25805975 This task presented emotional distractor pictures (aversive vs. neutral) simultaneously with Go/NoGo stimuli (square vs. circle) that required a button press or withholding of the press, respectively. RTN4 drug nicotine 25542919 Reduced Influence of Monetary Incentives on Go/NoGo Performance During Smoking Abstinence. RTN4 drug nicotine 25542919 Eighteen smokers performed an incentivized Go/NoGo task on 2 occasions, once after smoking as usual prior to the session, and once after undergoing 12 hr abstinence. RTN4 addiction reward 25542919 Participants could earn up to $5.00 ($2.50 per session) based on their performance on reward blocks of the Go/NoGo task. RTN4 addiction addiction 25195081 The meta analysis used fixed effects models to integrate results from 97 studies that compared groups with heavy substance use or addiction like behaviours with healthy control participants on two experimental paradigms commonly used to assess response inhibition: the Go/NoGo task, and the Stop Signal Task (SST). RTN4 drug alcohol 25189856 The NoGo N2 was larger for alcohol cues and acute alcohol decreased the amplitude of the NoGo N2 for alcohol cues. RTN4 drug opioid 25171718 Participants with histories of illicit heroin use (n = 24), former heroin users stabilized on prescribed methadone (methadone maintenance treatment; MMT) (n = 29), licit opioid prescriptions for chronic pain without history of abuse or dependence (n = 28) and healthy controls (n = 28) were recruited and tested on a task battery that included measures of cognitive impulsivity (Cambridge Gambling Task, CGT), motor impulsivity (Affective Go/NoGo, AGN) and non planning impulsivity (Stockings of Cambridge, SOC). RTN4 addiction dependence 25171718 Participants with histories of illicit heroin use (n = 24), former heroin users stabilized on prescribed methadone (methadone maintenance treatment; MMT) (n = 29), licit opioid prescriptions for chronic pain without history of abuse or dependence (n = 28) and healthy controls (n = 28) were recruited and tested on a task battery that included measures of cognitive impulsivity (Cambridge Gambling Task, CGT), motor impulsivity (Affective Go/NoGo, AGN) and non planning impulsivity (Stockings of Cambridge, SOC). RTN4 drug alcohol 24835220 Event related potentials (ERPs) elicited by a Go/NoGo task were recorded twice within a 2 year interval in 57 undergraduate students (25 controls, 22 binge drinkers, and 10 ex binge drinkers) with no personal or family history of alcoholism or psychopathological disorders. RTN4 addiction intoxication 24835220 Event related potentials (ERPs) elicited by a Go/NoGo task were recorded twice within a 2 year interval in 57 undergraduate students (25 controls, 22 binge drinkers, and 10 ex binge drinkers) with no personal or family history of alcoholism or psychopathological disorders. RTN4 drug alcohol 24835220 The results showed that the amplitude of NoGo P3 over the frontal region correlated with an earlier age of onset of regular drinking as well as with greater quantity and speed of alcohol consumption. RTN4 drug alcohol 24835220 Regression analysis showed that NoGo P3 amplitude was significantly predicted by the speed of alcohol intake and the age of onset of regular drinking. RTN4 addiction intoxication 24835220 The group comparisons showed that, after maintaining a binge drinking pattern for at least 2 years, binge drinkers displayed significantly larger NoGo P3 amplitudes than controls, whereas ex binge drinkers were in an intermediate position between the two other groups (with no significant differences with respect to controls or binge drinkers). RTN4 drug nicotine 24828276 Participants prenatally exposed to nicotine exhibited a weaker response in the anterior cingulate cortex (t168 = 4.46; peak Montreal Neurological Institute [MNI] coordinates x = 2, y = 20, z = 30; familywise error [FWE] corrected P = .003), the right inferior frontal gyrus (t168 = 3.65; peak MNI coordinates x = 44, y = 38, z = 12; FWE corrected P = .04), the left inferior frontal gyrus (t168 = 4.09; peak MNI coordinates x = 38, y = 36, z = 8; FWE corrected P = .009), and the supramarginal gyrus (t168 = 5.03; peak MNI coordinates x = 64, y = 28, z = 22; FWE corrected P = .02) during the processing of the NoGo compared to neutral stimuli, while presenting a decreased volume in the right inferior frontal gyrus.

RTN4 drug alcohol 23709633 Reduced intra individual reaction time variability during a Go NoGo task in detoxified alcohol dependent patients after one right sided dorsolateral prefrontal HF rTMS session. RTN4 drug alcohol 23709633 We examined the effect of a single right DLPFC HF rTMS session on commission errors, mean reaction times (RTs) and intra individual reaction time variability (IIRTV) during a Go NoGo task (50% Go/50% NoGo condition) in 29 alcohol dependent patients. RTN4 drug alcohol 23200160 One hundred sixty four individuals with a range of drinking from non treatment seeking adults with problematic alcohol use to treatment seeking adults with alcohol dependence completed a Go/NoGo task while undergoing functional magnetic resonance imaging. RTN4 addiction dependence 23200160 One hundred sixty four individuals with a range of drinking from non treatment seeking adults with problematic alcohol use to treatment seeking adults with alcohol dependence completed a Go/NoGo task while undergoing functional magnetic resonance imaging. RTN4 addiction relapse 23200160 One hundred sixty four individuals with a range of drinking from non treatment seeking adults with problematic alcohol use to treatment seeking adults with alcohol dependence completed a Go/NoGo task while undergoing functional magnetic resonance imaging. RTN4 drug nicotine 23194834 Haloperidol (2 mg), a dopamine D2/D3 receptor antagonist, and placebo were administered to 25 smokers and 25 non smoking controls in a double blind randomized cross over design while performing a Go/NoGo task during fMRI scanning. RTN4 drug nicotine 23194834 In addition, smokers showed behavioral deficits on the Go/NoGo task as well as hypoactivity in the left IFG, right MFG and ACC after placebo, supporting the hypothesis of a hypoactive prefrontal system in smokers. RTN4 drug nicotine 21526125 Deficits in inhibitory control in smokers during a Go/NoGo task: an investigation using event related brain potentials. RTN4 drug nicotine 21526125 Participants (19 smokers and 20 non smoking controls) performed a smoking Go/NoGo task. RTN4 drug nicotine 21526125 Reduced NoGo N2 amplitudes in smokers relative to controls were accompanied by decreased task performance, whereas no differences between groups were found in P3 amplitudes. RTN4 drug cocaine 19830263 This study used a flanker task with NoGo elements to investigate frontal executive function deficits in 19 cocaine abusers. RTN4 drug cocaine 19501630 cocaine) rewards were examined in four rhesus monkeys performing a visual Go Nogo decision task. RTN4 addiction reward 19501630 Task related striatal neurons increased firing to one or more of the specific events that occurred within a trial represented by (1) Target stimuli (Go trials) or (2) Nogotarget stimuli (Nogo trials), and (3) Reward delivery for correct performance. RTN4 drug alcohol 19250950 Only the NoGo P3 reduction was correlated with alcohol consumption. RTN4 drug nicotine 19220487 This study examined differences in attentional processing between nonsmokers, satiated smokers and overnight nicotine deprived smokers by comparing the amplitude of the P300 (P3) component of the event related brain potential (ERP) elicited during a go nogo task. RTN4 drug nicotine 19220487 Nonsmokers relative to smokers had greater nogo P3 amplitude. RTN4 addiction withdrawal 19220487 Carrying the A1 allele at the dopamine receptor D2 (DRD2) Taq1A polymorphism site moderated the effects of withdrawal on nogo P3 amplitude, suggesting the A1 allele is a vulnerability marker for withdrawal related attentional deficits. RTN4 drug opioid 18485592 We used functional magnetic resonance imaging (fMRI) to examine the neural substrates of response inhibition and competition in 18 healthy controls and assess the frontal neurocognition in 30 abstinent heroin dependents (AHD) as they performed a Go/NoGo Association task with reaction times recorded spontaneously. RTN4 drug alcohol 18373725 Impulsive errors on a Go NoGo reaction time task: disinhibitory traits in relation to a family history of alcoholism. RTN4 drug alcohol 18373725 We predicted that healthy young adults with a family history of alcoholism (FH+) who also displayed externalizing behavior characteristics (low scores on the California Psychological Inventory Sociability Scale; CPI So) would exhibit more impulsive responding (false alarms) on a Go NoGo reaction time task. RTN4 drug alcohol 17826793 Sixteen healthy volunteers and 16 detoxified alcohol dependent patients completed an auditory go/nogo paradigm. RTN4 drug cocaine 15590917 Using a GO NOGO response inhibition task in which working memory (WM) demands can be varied, we demonstrate that the compromised abilities of cocaine users to exert control over strong prepotent urges are associated with reduced activity in anterior cingulate and right prefrontal cortices, two regions thought to be critical for implementing cognitive control. RTN4 drug cocaine 12944513 Cingulate hypoactivity in cocaine users during a GO NOGO task as revealed by event related functional magnetic resonance imaging. RTN4 drug alcohol 12909389 The cognitive event related potentials were studied in a group of 55 alcoholic patients, paired in age and sex with a group of 18 control subjects, using a protocol oddball (visual and auditory) and a protocol VCN Go/Nogo. RTN4 drug alcohol 12909389 Using a Go/Nogo paradigm, a significant difference on the final part of the VCN appears between alcoholic and pilot subjects. RTN4 drug alcohol 9811199 The ERP field differed between alcoholics and controls in the Go condition (P < 0.05) and NoGo anteriorization in alcoholics was correlated inversely with Novelty Seeking in Cloninger's Temperament and Character Inventory (r= 0.67, P < 0.01). RTN4 addiction relapse 9811199 The ERP field differed between alcoholics and controls in the Go condition (P < 0.05) and NoGo anteriorization in alcoholics was correlated inversely with Novelty Seeking in Cloninger's Temperament and Character Inventory (r= 0.67, P < 0.01). RTN4 drug nicotine 8880370 Smoking did not differentially affect the dominance groups unless gender was taken into account, and the most striking interactions between smoking and dominance groups were noted for the NoGo trials. RTN4 drug nicotine 8880370 As expected, smoking decreased the amplitude of the early component of the NoGo CNV for telic dominant women, but increased it for paratelic dominant women; no significant differences were found for the late component.

SH2D3C drug nicotine 18395624 By itself, adolescent nicotine exposure evoked sex selective deficits in cerebrocortical HC3 binding while elevating ChAT in young adulthood in striatum and midbrain. SH2D3C addiction withdrawal 18088441 When mice were treated with an antisense oligodeoxynucleotide (AS ODN) against ChAT, which decreased ChAT signals in the dorsal horn and DRG, but not in motor neurons, they showed a significant decrease in nociceptive thresholds in paw pressure and thermal paw withdrawal tests.

SH2D3C drug nicotine 15066159 Animals neonatally treated with quinpirole demonstrated a significant 36% decrease of ChAT in the hippocampus compared to saline controls that was partially eliminated by nicotine. SH2D3C drug nicotine 14970833 Prenatal nicotine exposure had only minor effects on nAChRs but produced persistent cholinergic hypoactivity (reduced HC 3 binding relative to ChAT) throughout adolescence and into adulthood (PN75). SH2D3C drug alcohol 12831864 In addition, the somatic size of ChAT IR neurons was reduced by ethanol intake, and withdrawal further aggravated neuronal atrophy. SH2D3C addiction withdrawal 12831864 In addition, the somatic size of ChAT IR neurons was reduced by ethanol intake, and withdrawal further aggravated neuronal atrophy. SH2D3C drug nicotine 12784097 Adolescent nicotine treatment also produced lasting decrements in HC 3 binding that were separable from effects on ChAT, suggesting cholinergic synaptic impairment. SH2D3C drug nicotine 10915806 During nicotine treatment and for 1 month after the termination of treatment, ChAT activity was reduced significantly in the midbrain but not in the other regions. SH2D3C addiction withdrawal 10487390 There were no significant differences in the density of the ChAT IR hippocampal fiber network when the pure withdrawal and withdrawal + vehicle groups were compared to the withdrawal + GM1 or withdrawal + piracetam groups. SH2D3C addiction withdrawal 10487390 In contrast, the number of ChAT IR interneurons in the hippocampal formation was higher in the withdrawal + GM1 or withdrawal + piracetam groups than in the pure withdrawal and withdrawal + vehicle groups. SH2D3C drug cocaine 7877755 Choline acetyltransferase (ChAT) activity was measured in discrete areas of rat brain after chronic, unlimited access to self administration of cocaine.

SH2D3C addiction withdrawal 7877755 Mean activity of ChAT was reduced by approximately 30% in the nucleus accumbens, both on the last day of cocaine access and after 3 weeks cocaine withdrawal. SH2D3C drug opioid 8149590 The effect of prenatal exposure to methadone via maternal osmotic minipumps on the expression of acetylcholinesterase (AChE) and choline acetyltransferase (ChAT) has been studied by light microscopy in the striatum of male and female rats. SH2D3C drug opioid 8149590 At postnatal day 10, rats of both sexes exhibit reduced intensity of ChAT immunoreactive staining in striatal neurons in the methadone treated group in comparison to either untreated or water treated controls. SH2D3C drug opioid 8149590 Although the number and distribution of ChAT immunoreactive neurons appear to be similar across all three groups, the size (cross sectional area) of these neurons is significantly smaller in the methadone treated animals. SH2D3C drug opioid 8149590 By postnatal day 22, there are no differences in the ChAT immunoreactivity of striatal neurons between the water treated and methadone treated animals. SH2D3C drug opioid 8149590 Thus, prenatal exposure to methadone appears to produce a delay in the expression of ChAT in striatal neurons. SH2D3C drug alcohol 7748324 Specific activity of GAD but not ChAT was found to be significantly decreased in hippocampi of ethanol dependent animals following injection of NMDA, suggesting that chronic ethanol administration sensitizes GABAergic neurons to the toxic effects of excitatory amino acid transmitters. SH2D3C drug nicotine 4064913 No significant change in cholineacetyltransferase (ChAT) activity or number of muscarinic binding sites in brain was observed after 9 or 41 weeks of nicotine treatment. SH2D3C drug opioid 6685808 The results demonstrate that neither short nor long term morphine treatment had an effect on choline acetyltransferase (ChAT) activity or 3H quinuclidinylbenzilate (3HQNB) binding in discrete striatal regions of the rat brain. SH2D3C drug alcohol 7198309 The activities of acetylcholinesterase (AChE) and choline acetyltransferase (ChaT) in the cerebral cortex, cerebellum, hypothalamus, hippocampus, midbrain and pons of adult, male mice injected with 2 g/kg ethanol and of control mice injected with physiological saline, were determined by spectrophotometric methods. SH2D3C drug alcohol 7198309 All animals were killed 30 min after injection between 11.00 h and 12.00 h. Results show that the acute dose of ethanol significantly decreased AChE activity only in the cerebral cortex whereas ChaT activity was reduced in the cerebral cortex, hypothalamus and hippocampus. SH2D3C drug alcohol 7198309 These findings show that the effect of an acute dose of ethanol on the cholinergic system of mouse brain is mediated through its effect on AChE and ChaT in specific regions. SH2D3C drug alcohol 6994921 Eighteen weeks of ethanol consumption in a liquid diet reduced rat striatal and mammillary body choline acetylase (ChAT) by 53% and 58%, respectively. IL1B drug opioid 32733481 Opioids non stereoselectively activate the TLR4 pathway, and together with the subsequent release of pro inflammatory cytokines such as IL 1 by glia, this TLR4 signaling initiates the central immune signaling response and modifies opioid pharmacodynamics. IL1B drug alcohol 31854009 C57BL/6J male and female mice were provided a 2 bottle choice of alcohol at increasing concentrations (3, 6, 9, and 12%, 4 days each) or water, and some were treated with daily injections of an NLRP3 inhibitor (MCC950), a caspase 1 inhibitor (VX765), IL 1 receptor antagonist (IL 1ra; anakinra), or vehicle injection.

IL1B drug alcohol 30791967 In this study, we generated naïve, non dependent (Non Dep) and dependent (Dep) male mice using a paradigm of chronic intermittent ethanol vapor exposure interspersed with two bottle choice to examine 1) the expression of IL 1β, 2) the role of the IL 1 system on GABAergic transmission, and 3) the potential interaction with the acute effects of ethanol in the CeA. IL1B drug cannabinoid 30584942 In addition, mechanistically at the molecular level, these effects are elicited via up regulation of the cannabinoid type 2 receptor, up regulating the level of β endorphin, and reducing the levels of IL 1, NO and PGE2. IL1B addiction reward 30075289 Furthermore, it has not been evaluated whether the involvement of IL 1 in associative learning extends to classically conditioned appetitive behaviors, such as conditioned place preference (CPP). IL1B drug cannabinoid 30046349 Δ9 THC/sesame oil therapy showed similar effects to MTX in neutralizing the inflammatory process of AIA, through attenuating erythrocyte sedimentation rate (ESR) scores and proinflammatory cytokines, including tumor necrosis factor alpha (TNF α), interleukin 1 beta (IL 1β), and interleukin 6 (IL 6) levels, to normal values. IL1B drug alcohol 29178411 We found that during abstinence, alcohol binge drinkers had elevated plasma levels of oleoylethanolamide, palmitoleoylethanolamide, arachidonoylethanolamide, dihomo γ linolenoyl ethanolamide and linoleoyl ethanolamide, which positively correlated with changes in the mRNA expression of key inflammatory markers in peripheral blood mononuclear cells, such as toll like receptors (TLR4), pro inflammatory cytokines/chemokines interleukin 1 beta, interleukin 6 and monocyte chemoattractant protein 1, and cyclooxygenase 2.

IL1B drug opioid 29111854 We observed differential methylation of Bdnf and Il6 in the pons, Nr3c1 in the cerebellum, and Il1b in the hippocampus in response to acute morphine exposure (all P value < 0.05). IL1B drug opioid 28178176 In response to LPS, there was a significant increase in the expression of the pro inflammatory cytokine/chemokine genes interleukin 1 beta (Il 1β), interleukin 6 (Il 6), C C motif chemokine ligand 2 (Ccl2), C C motif chemokine ligand 7 (Ccl7), C X C motif chemokine ligand 1 (Cxcl1), and C X C motif chemokine ligand 3 (Cxcl3) and a significant decrease in the anti inflammatory NLRP12 gene in both morphine tolerant and placebo control rats compared to saline treated rats, although the changes were greater in the placebo control animals. IL1B drug alcohol 28095363 Also, alcohol administration augmented lipid peroxidation, mitochondrial oxidized glutathione (GSSG), interleukin 1 beta (IL 1β), tumor necrosis factor alpha (TNF α) and Bax levels in isolated hippocampal tissues.

IL1B addiction reward 27273552 Here, we examined the role of interleukin 1 (IL 1) and tumor necrosis factor α (TNF α) in regulation of voluntary alcohol consumption, alcohol reward and stress induced drinking. IL1B drug alcohol 27273552 Mice with a deletion of the IL 1 receptor I gene (IL 1RI KO) exhibited modestly decreased alcohol consumption. IL1B addiction sensitization 26773297 This sensitization enhances the production of various proinflammatory cytokines such as interleukin 1 (IL 1) and tumor necrosis factor alpha, thereby contributing to hepatocyte dysfunction, necrosis, and apoptosis and the generation of extracellular matrix proteins leading to fibrosis/cirrhosis. IL1B drug alcohol 26773297 As IL 1 is clearly linked to key clinical symptoms of acute alcoholic hepatitis such as fever, neutrophilia, and wasting, interfering with the IL 1 pathway might be an attractive treatment strategy in the future.

IL1B drug alcohol 26365025 Moreover, the role of IL 1 receptor signaling in the amygdala on ethanol consumption was assessed. IL1B drug alcohol 26365025 Bilateral infusions of IL 1 receptor antagonist (IL 1Ra) reduced ethanol consumption when infused into the BLA but not the CeA. IL1B drug alcohol 26365025 The current findings highlight a specific role for IL 1 receptor signaling in modulating binge like ethanol consumption and indicate that proinflammatory cytokines can be induced prior to dependence or any evidence of neuronal cell death.

IL1B drug opioid 26363312 No difference in cortisol production was initially observed between the two groups, however, when participants were separated based on their genotype for two single nucleotide polymorphisms in the promoter of the IL1B gene, which have been shown to occur at a higher frequency in opioid dependent populations, individuals carrying the 511T and 31 C alleles ( 511 C/T, 31 C/T or 511 T/T, 31 C/C) had a significantly (p<0.05) higher cortisol levels compared to individuals homozygous for the 511 C and 31T alleles. IL1B drug alcohol 25930080 In vivo depletion of Kupffer cells (KCs) by liposomal clodronate reduced liver injury and the expression of Il1b, but not Cxcl1, Cxcl2, and Cxcl5, suggesting that KCs are partly associated with liver injury, but not neutrophil recruitment, in a chronic binge ethanol feeding model. IL1B addiction intoxication 25930080 In vivo depletion of Kupffer cells (KCs) by liposomal clodronate reduced liver injury and the expression of Il1b, but not Cxcl1, Cxcl2, and Cxcl5, suggesting that KCs are partly associated with liver injury, but not neutrophil recruitment, in a chronic binge ethanol feeding model. IL1B drug nicotine 25858413 Moreover, recent studies suggested that IL 1 participates in the progression of lung disease in smokers, which are overrepresented in schizophrenia. IL1B drug alcohol 25852553 IL 1 interacts with ethanol effects on GABAergic transmission in the mouse central amygdala. IL1B drug alcohol 25852553 Overall, our data suggest that the IL 1 system is involved in basal GABAergic transmission and that IL 1β interacts with the ethanol induced facilitation of CeA GABAergic transmission. IL1B drug alcohol 25839897 Gene expression studies identified the interleukin 1 receptor type I (IL 1R1) as part of a pathway associated with a genetic predisposition to high alcohol consumption, and lack of the endogenous IL 1 receptor antagonist (IL 1ra) strongly reduced ethanol intake in mice. IL1B drug alcohol 25839897 Conversely, deletion of Il1r1 (the gene encoding the IL 1 receptor type I, IL 1R1) reduces sensitivity to the sedative effects of ethanol and flurazepam and increases the severity of acute ethanol withdrawal. IL1B drug benzodiazepine 25839897 Conversely, deletion of Il1r1 (the gene encoding the IL 1 receptor type I, IL 1R1) reduces sensitivity to the sedative effects of ethanol and flurazepam and increases the severity of acute ethanol withdrawal.

IL1B drug alcohol 25582105 Kupffer cells and IL 1β were required for the hepatic iNKT accumulation, as either blocking IL 1β signaling with a recombinant IL 1 receptor antagonist (IL 1Ra), depleting Kupffer cells by clodronate liposomes, or specifically silencing IL 1β in Kupffer cells by nanoparticle encapsulated siRNA, resulted in inhibited hepatic iNKT cell accumulation and activation, as well as amelioration of alcoholic fatty liver. IL1B addiction intoxication 25156612 Although cytokine and region dependent central IL 6 expression was generally increased and tumor necrosis factor alpha decreased during intoxication, IL 1 expression exhibited increases during withdrawal.

IL1B drug alcohol 23206318 Ethanol treatment of brain slice culture released HMGB1 into the media and induced the proinflammatory cytokine, interleukin 1 beta (IL 1β). IL1B drug alcohol 22921768 Taken together, these studies demonstrate that the behavioral sequelae of acute illness and ethanol withdrawal are similar in nature, while antagonist studies suggest that these behavioral alterations are not reversed by blockade of IL 1 receptors or inhibition of prostaglandin synthesis.

HDAC9 drug alcohol 28771357 Class I HDAC Inhibitors: Potential New Epigenetic Therapeutics for Alcohol Use Disorder (AUD). HDAC9 drug alcohol 28771357 Alcohol exposure has been widely demonstrated to modulate epigenetic mechanisms, such as histone acetylation/deacetylation balance, in part via histone deacetylase (HDAC) inhibition. HDAC9 drug alcohol 28682229 Furthermore, we recently showed that a single ethanol exposure inhibits HDAC activity and increases both H3 and H4 histone acetylation within the amygdala of rats. HDAC9 drug alcohol 28682229 In neuronal cell line culture, ethanol was shown to induce HDAC expression. HDAC9 drug alcohol 28682229 Numerous studies have shown that HDAC inhibitors are able to counter ethanol induced behaviors and the ethanol induced changes in the levels of HDAC and/or levels of acetylated HDAC. HDAC9 drug alcohol 28682229 For example, trichostatin A (TSA) treatment caused the reversal of ethanol induced tolerance, anxiety, and ethanol drinking by inhibiting HDAC activity, thereby increasing histone acetylation in the amygdala of rats. HDAC9 drug alcohol 28682229 Another study demonstrated that TSA prevented the development of ethanol withdrawal induced anxiety in rats by rescuing deficits in histone acetylation induced by increased HDAC activity in the amygdala.

HDAC9 addiction sensitization 28682229 We have demonstrated that treatment with the HDAC inhibitor sodium butyrate blocks both the development and the expression of ethanol induced behavioral sensitization in mice. HDAC9 drug alcohol 28682229 In this context, converging evidence indicates that HDAC inhibitors could be useful in counteracting ethanol induced gene regulations via epigenetic mechanisms, that is, HDAC inhibitors could affect different acetylation sites and may also alter the expression of different genes that could in turn counteract the effect of ethanol. HDAC9 drug alcohol 28682229 Recent work in rodents has shown that systemic administration of pan HDAC class I and II inhibitors, TSA and N hydroxy N phenyl octanediamide [SuberoylAnilide Hydroxamic Acid] (SAHA), and of the more selective inhibitor (mainly HDAC1 and HDAC9) MS 275, decrease binge like alcohol drinking in mice.

HDAC9 drug alcohol 28433417 There is growing evidence that small molecule inhibitors of epigenetic modulators, such as histone deacetylases (HDAC) and DNA methyltransferases (DNMT), can reduce voluntary ethanol consumption in animal models, but molecular and cellular processes underlying this behavioral effect are poorly understood.

HDAC9 drug alcohol 27238566 Alcohol increased Hdac gene expression in blood and nalmefene prevented the increases in Hdacs 3, 8, 5, 7, 9, 6 and 10. HDAC9 drug alcohol 27238566 In the other tissues, alcohol and nalmefene either did not alter the gene expression of Hdacs, as in the prefrontal cortex, or a tissue Hdac specific effect was observed. HDAC9 drug cocaine 27180319 Inhibition of HAT by curcumin (100mg/kg) before each SD blocked the increase in the conditioned reinforcing effects of 1mg/kg of cocaine, while inhibition of HDAC by valproic acid (500mg/kg) before social stress potentiated cocaine induced CPP.

HDAC9 drug alcohol 24968059 The lower dose of ethanol (1 g/kg) produced neither anxiolysis, nor inhibited the HDAC and DNMT activities in the amygdala and BNST, except DNMT activity in BNST was attenuated. HDAC9 drug alcohol 24968059 DNMT activity in the amygdala and BNST, and nuclear HDAC activity in the amygdala, but not in the BNST were also inhibited by these doses of ethanol.

HDAC9 addiction intoxication 23423140 Similarly, we find that increasing histone acetylation via systemic treatment with several histone deacetylase (HDAC) inhibitors reduces mice binge like alcohol drinking. HDAC9 drug alcohol 23423140 We further report that systemic administration of the FDA approved HDAC inhibitor, SAHA, inhibits the motivation of rats to seek alcohol. HDAC9 drug alcohol 23423140 Importantly, the actions of both DNMT and HDAC inhibitors are specific for alcohol, as no changes in saccharin or sucrose intake were observed. HDAC9 drug alcohol 23423140 Our study therefore highlights the possibility that DNMT and HDAC inhibitors can be used to treat harmful alcohol abuse. HDAC9 addiction relapse 23297220 Nonspecific histone deacetylase (HDAC) inhibition has been shown to facilitate the extinction of drug seeking behavior in a manner resistant to reinstatement. HDAC9 addiction relapse 23297220 A key open question is which specific HDAC is involved in the extinction of drug seeking behavior. HDAC9 drug opioid 23273833 In the current work we explored how the balance of histone acetyltransferase (HAT) versus histone deacetylase (HDAC) might regulate these morphine induced changes. HDAC9 drug opioid 23273833 Moreover, we observed a decrease in HDAC activity in the spinal cords of morphine treated mice while overall HAT activity was unchanged, suggesting a shift toward a state of enhanced histone acetylation. HDAC9 drug alcohol 23110077 Brains were then removed 30 min after a saline or 2 g/kg ethanol challenge to assess i) gene expression using PCR array targeting 84 epigenetic related genes and ii) histone deacetylases (HDAC), histone acetylases (HAT) and DNA methyltransferases (DNMT) activities as well as H4K12 acetylation. HDAC9 drug alcohol 23110077 Whereas global HAT or DNMT activity was not affected, global HDAC activity was reduced after an acute ethanol injection. HDAC9 drug alcohol 23110077 HDAC inhibition occurred in all ethanol treated mice but with a lesser extent in sensitized animals. HDAC9 drug opioid 23035088 We found that CPA extinction training induced an increase in recruiting cAMP response element binding protein (CREB) to and acetylation of histone H3 at the promoters of BDNF exon I transcript and increased BDNF mRNA and protein expression in the ventromedial prefrontal cortex (vmPFC) of acute morphine dependent rats and that such epigenetic regulation of BDNF gene transcription could be facilitated or diminished by intra vmPFC infusion of HDAC inhibitor trichostatin A or extracellular signal regulated kinase (ERK) inhibitor U0126 (1,4 diamino 2,3 dicyano 1,4 bis(methylthio)butadiene) before extinction training. HDAC9 addiction addiction 22796363 Recent studies have also implicated histone deacetylases (HDACs) and acetyltransferases (HATS) in regulation of drug addiction, and HDAC inhibitors (HDACi) have been reported as transcriptional modulators of monoaminergic neurotransmission. HDAC9 drug alcohol 22796363 The effects of ethanol on serotonin and 5 HT3, and the role HDACs, HDAC activity and the HDACi, trichostatin A (TSA), play in alcohol induced serotonergic effects were studied. HDAC9 drug alcohol 22796363 Further, ethanol significantly increased HDACs 1 and 3 genes accompanied by an increased in HDAC activity while TSA significantly inhibited HDACs. HDAC9 drug alcohol 22796363 In summary, our studies demonstrate some of the novel properties of HDAC inhibitors and contribute to the understanding of the mechanisms involve in alcohol serotonergic modulation in the CNS. HDAC9 drug amphetamine 22470541 These results suggest that METH induced alterations in global gene expression seen in rat NAC might be related, in part, to METH induced changes in histone acetylation secondary to changes in HAT and HDAC expression.

HDAC9 drug cocaine 20383415 Our results showed that pretreatment with HDAC inhibitor (sodium butyrate), potentiated cocaine induced CPP, but did not itself lead to conditioned preferences, or aversions. HDAC9 addiction reward 20383415 Our results showed that pretreatment with HDAC inhibitor (sodium butyrate), potentiated cocaine induced CPP, but did not itself lead to conditioned preferences, or aversions. HDAC9 drug cocaine 20010550 The effect of the HDAC inhibitor is attributed to the increased elevation of histone acetylation induced by chronic, but not acute, cocaine experience.

HDAC9 addiction sensitization 18848971 Histone deacetylase (HDAC) plays an important role in chromatin remodeling in response to a variety of neurochemical signalings and behavioral manipulations, and may be a therapeutic target for modulation of psychostimulant behavioral sensitization. HDAC9 addiction sensitization 18848971 Thus, HDACi may interact additively with psychostimulants at both histone acetylation and CREB phosphorylation through the CREB:HDAC protein complex in the striatum to modulate DeltaFosB protein levels and psychomotor behavioral sensitization. HDAC9 drug cocaine 18799668 Using the fixed ratio 1 schedule, we found that the histone deacetylase (HDAC) inhibitors trichostatin A and phenylbutyrate dose dependently reduced cocaine self administration. HDAC9 drug cocaine 18799668 Under the progressive ratio schedule, both trichostatin A and depudecin significantly reduced the breaking point, indicating that HDAC inhibition attenuated the motivation of rats for cocaine. HDAC9 drug cocaine 18799668 This observation was correlated with measurements of HDAC activity in the frontal cortex, which was inhibited in response to cocaine, but not to sucrose self administration. HDAC9 addiction dependence 18799668 Together, the data show that epigenetic regulation of gene transcription in adult brain is able to influence a motivated behavior and suggest that HDAC inhibition may counteract the neural sensitization leading to drug dependence.

HDAC9 drug alcohol 18385331 We found that the anxiolytic effects produced by acute alcohol were associated with a decrease in histone deacetylase (HDAC) activity and increases in acetylation of histones (H3 and H4), levels of CREB (cAMP responsive element binding) binding protein (CBP), and neuropeptide Y (NPY) expression in the amygdaloid brain regions of rats. HDAC9 drug alcohol 18385331 However, the anxiety like behaviors during withdrawal after chronic alcohol exposure were associated with an increase in HDAC activity and decreases in acetylation of H3 and H4, and levels of both CBP and NPY in the amygdala.

TRH drug cocaine 15003716 Like cocaine (10 mg/kg), TRH (10 mg/kg) increased the basal activation of rats; however, when given in combination with cocaine (10 mg/kg), TRH (5 10 mg/kg) did not change the locomotor effect of cocaine.

TRH addiction sensitization 15003716 Given acutely with cocaine on day 10 to cocaine treated animals, TRH (5 10 mg/kg) did not change the expression of cocaine sensitization. TRH drug cocaine 15003716 The response to TRH (5 10 mg/kg) was stronger in repeated cocaine treated rats than in saline injected ones; similarly, the response to cocaine (10 mg/kg) was more potent in TRH treated animals compared to saline injected ones (cross sensitization).

TRH addiction sensitization 15003716 Moreover, cross sensitization between cocaine and TRH has also been demonstrated. TRH drug cocaine 15003716 These findings also may provide an insight into the relationship between TRH and cocaine in humans exposed to the psychostimulant. TRH drug alcohol 12410778 About one third of all alcoholics also displayed a blunted thyroid stimulation hormone (TSH) response in the thyrotrophin releasing hormone test (TRH test). TRH drug alcohol 12410778 We suggest that a reduction in peripheral thyroid hormones may be caused by a direct toxic effect of alcohol on the thyroid gland, which induces a central compensatory activation of the hypothalamic pituitary axis with an increased TRH release. TRH drug cocaine 12213229 Cocaine regulates TRH related peptides in rat brain. TRH drug cocaine 12213229 Cocaine administration has previously been reported to alter the levels of prepro TRH mRNA and TRH (pGlu His Pro NH(2)) in the limbic system of rats (J. Neurochem. TRH drug cocaine 12213229 We have now demonstrated that a previously unrecognized family of TRH like peptides is involved in the actions of cocaine. TRH drug cocaine 12213229 Acute cocaine produced a 4.1 fold increase in Val(2) TRH level in medulla while Val(2) TRH and Tyr(2) TRH, increased 6.2 and 2.9 fold, respectively in pyriform cortex PYR. TRH drug cocaine 12213229 TRH and Leu(2) TRH, decreased 47 and 93%, respectively in the nucleus accumbens (AM) while other EEP IR peaks decreased 50 100% consistent with the significant decrease in total EEP IR in the AMs following acute cocaine treatment. TRH drug cocaine 12213229 Because 2h is too short a time to alter levels of neuropeptides via changes in the rate of biosynthesis, the acute cocaine induced elevation or reduction in TRH and related peptides is most likely due to suppression or stimulation, respectively, of the corresponding peptide secretion rate. TRH drug cocaine 12213229 Because TRH and TRH like peptides have antidepressant, analeptic and euphorigenic properties, we conclude that these endogenous substances are potential mediators of both the cocaine "high" and withdrawal symptoms.

TRH addiction withdrawal 11948251 The aim of the present study was to determine which of the proTRH derived peptides are affected by opiate withdrawal in the PAG. TRH addiction withdrawal 11948251 Opiate withdrawal caused a significant change in the level of some post translational processing products derived from the TRH precursor. TRH addiction withdrawal 11948251 In the PAG, opiate withdrawal resulted in an accumulation of the intervening preproTRH(83 106) peptide from the N terminal side of the prohormone, while the levels of the C terminal preproTRH(208 285) peptide were reduced, with no change in preproTRH(25 50) or TRH, itself, as compared to control animals. TRH addiction withdrawal 11948251 Opiate withdrawal in the lateral hypothalamus, unlike from the PAG, was accompanied by an increase in the concentration of TRH. TRH addiction withdrawal 11948251 Thus, these results demonstrate a region specific regulation of TRH prohormone processing in the brain, which may engage PC2, further suggesting a role for specific proTRH derived peptides in the manifestations of opiate withdrawal.

TRH addiction withdrawal 11701131 We have hypothesized that peptide products of proTRH may participate in the recovery from morphine withdrawal. TRH addiction withdrawal 11701131 These studies demonstrate that proTRH neurons in the ventrolateral PAG project to several regions of the brain that are involved in autonomic and behavioral regulation and thereby, may function as an integrating center to coordinate responses to opiate withdrawal.

TRH addiction reward 11104823 Considering the role played by dopamine in the central mechanisms of reward, these findings suggest that the inhibition of dopamine release could underlie the decreased appetitive behaviour induced by CART peptide (55 102) and TRH. TRH drug alcohol 10871700 Acute ethanol administration induces changes in TRH and proenkephalin expression in hypothalamic and limbic regions of rat brain. TRH drug alcohol 10871700 We measured TRH content and the levels of its mRNA in hypothalamic and limbic zones 1 24 h after acute ethanol injection. TRH drug alcohol 10871700 Wistar rats were administered one dose of ethanol (intraperitoneal, 3 g/kg body weight) and brains dissected in hypothalamus, hippocampus, amygdala, n. accumbens and frontal cortex, for TRH quantification by radioimmunoassay or for proTRH mRNA measurement by RT PCR.

TRH drug alcohol 10871700 The effect of ethanol was also studied in primary culture of hypothalamic cells; a fast and transient increase in proTRH mRNA was observed at 1 h of incubation (0.001% final ethanol concentration). TRH drug alcohol 10871700 Changes in the mRNA levels of proTRH and proenkephalin were quantified by in situ hybridization in rats administered ethanol intragastrically (2.5 g/kg). TRH drug alcohol 10871700 These results give support for TRH and enkephalin neurons as targets of ethanol and, as possible mediators of some of its observed behavioral effects. TRH drug alcohol 10684782 Combination pharmacotherapy: a mixture of small doses of naltrexone, fluoxetine, and a thyrotropin releasing hormone analogue reduces alcohol intake in three strains of alcohol preferring rats.

TRH addiction withdrawal 10657535 TRH and placebo tests were performed at random at 5 day intervals at the time of drug withdrawal and after 30 days. TRH drug cocaine 10657535 After 30 days of cocaine abstinence basal freeT4 plasma levels were significantly lower, and TSH levels and the TSH response to TRH were higher than in the first test. TRH drug cocaine 10657535 At the first examination, basal GH concentrations were similar in cocaine addicts and in control subjects and GH did not respond to TRH. TRH drug cocaine 10657535 After 30 days of abstinence, basal GH plasma levels were unmodified, but the TRH became stimulatory of GH release in cocaine deprived, but not in control subjects. TRH drug cocaine 10657535 In conclusion, in cocaine addicts, drug withdrawal is associated with a condition of subclinical hypothyroidism that makes the GH releasing machinery sensitive to TRH.

TRH drug alcohol 9347094 Effect of pyridostigmine on the thyroid stimulating hormone response to thyrotropin releasing hormone in abstinent alcoholics. TRH drug alcohol 9347094 Alcoholism is sometimes associated with a blunted thyroid stimulating hormone (TSH) response to thyrotropin releasing hormone (TRH; peak minus baseline < 5 mIU/liter), despite basal TSH and thyroid hormone levels within the normal range. TRH drug alcohol 9347094 Alcoholism is sometimes associated with a blunted thyroid stimulating hormone (TSH) response to thyrotropin releasing hormone (TRH; peak minus baseline < 5 mIU/liter), despite basal TSH and thyroid hormone levels within the normal range. TRH drug alcohol 9347094 To answer this question, 16 euthyroid male alcoholics (aged 38 to 50 years) with normal [n = 8; normal responder alcoholics (NRAs)] or blunted [n = 8; low responder alcoholics (LRAs)] TSH response to TRH were selected in a preliminary TRH test (200 micrograms in an intravenous bolus). TRH drug alcohol 9347094 These data argue against the possibility that an enhanced somatostatinergic tone is responsible for the blunted TSH response to TRH observed in some alcoholic patients. TRH drug psychedelics 9252236 The drugs used were the N methyl D aspartate receptor channel blocker ketamine; the competitive antagonists, 3 ((R) 2 carboxypiperazin 4 yl) propyl 1 phosphonic acid (D CPP) and D 2 amino 5 phosphonopentanoic acid (D AP5), and the positive modulator thyrotropin releasing hormone.

TRH drug cocaine 9243522 Effects of repeated cocaine administration on the thyrotropin releasing hormone level and receptors in the rat brain. TRH drug cocaine 9243522 The effects of single and repeated administration of cocaine on the thyrotropin releasing hormone (TRH) level and receptors in discrete rat brain structures were evaluated. TRH drug cocaine 9243522 The effects of single and repeated administration of cocaine on the thyrotropin releasing hormone (TRH) level and receptors in discrete rat brain structures were evaluated. TRH drug cocaine 9243522 A radioimmunoassay (RIA) study showed that a single dose of cocaine increased the TRH level in the striatum by 68%, but had no significant effect on the peptide content in the nucleus accumbens, hippocampus, amygdala, septum, hypothalamus, frontal and prefrontal cortex at 45 min after the drug injection. TRH drug cocaine 9243522 Repeated administration of cocaine increased the TRH level in the striatum by 89% at 45 min, and in the hippocampus by 26% at 72 h after the last dose. TRH drug cocaine 9243522 In vitro cocaine (10( 6) 10( 4) M) inhibited the K(+) stimulated release in a concentration dependent manner, but had no effect on the basal release of TRH from the striatum and nucleus accumbens of naive rats. TRH drug cocaine 9243522 Acute cocaine decreased the Bmax of TRH receptors in the striatum, but had no effect on the density and affinity of TRH receptors in other brain regions. TRH drug cocaine 9243522 Repeated administration of cocaine evoked a long lasting decrease in the Bmax of TRH receptors in the striatum (by c. 30%), whereas an increase in that parameter was observed in the frontal cortex. TRH drug cocaine 9243522 The Bmax and affinity of TRH receptors following repeated cocaine remained unchanged in the nucleus accumbens. TRH drug cocaine 9243522 The results obtained indicate that cocaine affects the TRH system mainly in the striatum, and to a lesser extent in the nucleus accumbens, cortex and hippocampus. TRH drug amphetamine 9243522 Furthermore, the above changes do not resemble those induced by amphetamine, which points to certain differences in adaptation of the TRH neuronal system to these psychostimulants.

TRH drug alcohol 9211435 On different days alcoholics were tested with TRH to evaluate possible alterations in the PRL pituitary reserve. TRH drug alcohol 8949950 Contrary to expectations, both PTU and TRH administration attenuated the transient rise in plasma T4 levels at postnatal days 10 16 in LS mice and in both instances this was associated with decreased CNS ethanol sensitivity (sleep time and hypothermia) in adults. TRH drug alcohol 8949950 However, the observation that neonatal administration of both TRH and PTU blunted the postnatal rise in thyroid levels in LS mice, yet both treatments resulted in a decrease in adult ethanol sensitivity in LS mice, indicates that the relationship between postnatal thyroid development and CNS ethanol sensitivity is more complex than originally hypothesized.

TRH drug alcohol 8800390 Dose response studies with thyrotropin releasing hormone: evidence for differential pituitary responses in men with major depression, alcoholism, or no psychopathology. TRH drug alcohol 8800390 A reduced thyrotropin (TSH) response to thyrotropin releasing hormone (TRH) has been reported in both alcoholic and depressed men. TRH drug alcohol 8800390 A reduced thyrotropin (TSH) response to thyrotropin releasing hormone (TRH) has been reported in both alcoholic and depressed men. TRH drug alcohol 8800390 To discern whether the pathophysiological basis of a reduced TSH response is similar in these two disorders, the present study compares the dose response patterns of TSH and prolactin (PRL) to TRH in depressed, alcoholic, and control men. TRH drug alcohol 8800390 Four doses of TRH (25, 100, 500, and 800 micrograms) were given at several day intervals to 6 men with major depression, 8 men with alcohol dependence, and 7 control men. TRH addiction dependence 8800390 Four doses of TRH (25, 100, 500, and 800 micrograms) were given at several day intervals to 6 men with major depression, 8 men with alcohol dependence, and 7 control men. TRH drug alcohol 8800390 Examination of the pattern of TRH induced TSH and PRL response revealed differences for each paired group comparison: depressed versus control, depressed versus alcoholic, and alcoholic versus control. TRH drug alcohol 8800390 Compared with controls, depressed men had low TSH and low PRL responses to TRH, whereas alcoholic men had low TSH responses and normal PRL responses. TRH drug alcohol 8800390 These findings suggest that the pathophysiological basis of a reduced TSH response to TRH is different in alcoholism, compared with depression.

TRH drug alcohol 8554651 We performed a combined TRH and gonadoliberin stimulation test on three well defined groups of nondepressed alcoholic men. TRH addiction withdrawal 8554651 We conclude that TRH stimulation test blunting appears to be related to factors operating in the withdrawal state and improves with continued abstinence. TRH drug opioid 8162104 In experiments on different species of animals respiratory stimulating effects of naloxone, TRH and its analogue RGH 2202 during respiratory rhythmogenesis disturbances, evoked by hyperventilation of lungs, bleeding and intoxication with cyanides or opiates, were investigated.

GDNF drug opioid 24399412 NCAM signaling mediates the effects of GDNF on chronic morphine induced neuroadaptations. GDNF addiction addiction 24399412 Glial cell line derived neurotrophic factor (GDNF) is a potent neurotrophic factor for midbrain dopamine (DA) neurons, while the DA neurons in the ventral tegmental area (VTA) is a crucial part of the neural circuits associated with drug addiction. GDNF addiction addiction 24399412 Recently, more and more evidence suggests that GDNF plays an important role in negatively regulating the neuroadaptations induced by chronic exposure to drugs, which was thought to be the neurobiological basis of drug addiction, but the underlying mechanism is still unknown. GDNF drug opioid 24399412 The purpose of this study was to investigate whether NCAM was involved in the effects of GDNF on the neuroadaptations induced by chronic morphine exposure. GDNF drug opioid 24399412 Moreover, pre treatment with the antibody could antagonize the effect of GDNF on inhibiting the neuroadaptations induced by chronic morphine exposure, including the decreases of the number and length of neurites and the size of cell bodies of VTA dopamine neurons, as well as the increase of tyrosine hydroxylase in the VTA dopamine neurons. GDNF drug opioid 24399412 These results suggest that NCAM signaling is involved in the negative regulatory effects of GDNF on chronic morphine induced neuroadaptations.

GDNF drug alcohol 23298382 GDNF is a novel ethanol responsive gene in the VTA: implications for the development and persistence of excessive drinking. GDNF drug alcohol 23298382 Glial cell line derived neurotrophic factor (GDNF) is a potent inhibitor of ethanol consumption and relapse, and GDNF heterozygous knockout mice display increased reward sensitivity to ethanol and consume more ethanol after a period of abstinence than their wild type littermates.

GDNF addiction reward 23298382 Glial cell line derived neurotrophic factor (GDNF) is a potent inhibitor of ethanol consumption and relapse, and GDNF heterozygous knockout mice display increased reward sensitivity to ethanol and consume more ethanol after a period of abstinence than their wild type littermates. GDNF drug alcohol 23298382 Here, we tested whether ethanol alters GDNF expression in the ventral tegmental area (VTA; GDNF's site of action) and/or the nucleus accumbens (NAc; the main source of GDNF), and if so, determine the role of the endogenous growth factor in the regulation of ethanol consumption. GDNF drug alcohol 23298382 Systemic administration of ethanol increased GDNF expression and protein levels in the VTA, but not the NAc. GDNF drug alcohol 23298382 Additionally, GDNF levels were elevated after an ethanol drinking session in rats that consumed ethanol in the intermittent access two bottle choice procedure for 1 week, but not 7 weeks. GDNF drug alcohol 23298382 Deprivation following 7 weeks of excessive ethanol intake reduced GDNF levels, while a short ethanol binge drinking period following deprivation upregulated GDNF expression. GDNF addiction intoxication 23298382 Deprivation following 7 weeks of excessive ethanol intake reduced GDNF levels, while a short ethanol binge drinking period following deprivation upregulated GDNF expression. GDNF drug alcohol 23298382 Importantly, knockdown of GDNF within the VTA using adenovirus expressing short hairpin RNA facilitated the escalation of ethanol drinking by ethanol naïve rats, but not by rats with a history of excessive ethanol consumption. GDNF addiction addiction 23298382 Importantly, knockdown of GDNF within the VTA using adenovirus expressing short hairpin RNA facilitated the escalation of ethanol drinking by ethanol naïve rats, but not by rats with a history of excessive ethanol consumption. GDNF drug alcohol 23298382 These results suggest that during initial ethanol drinking experiences, GDNF in the VTA is increased and protects against the development of excessive ethanol intake. GDNF drug amphetamine 22470541 Our study investigated the effects of a non toxic METH injection (20 mg/kg) on gene expression, histone acetylation, and the expression of the histone acetyltransferase (HAT), ATF2, and of the histone deacetylases (HDACs), HDAC1 and HDAC2, in that structure. GDNF drug amphetamine 22470541 The histone acetyltransferase, ATF2, showed significant METH induced increased in protein expression. GDNF drug alcohol 22238721 Positive autoregulation of GDNF levels in the ventral tegmental area mediates long lasting inhibition of excessive alcohol consumption. GDNF drug alcohol 22238721 Activation of the GDNF pathway in the ventral tegmental area (VTA), where the GDNF receptors are expressed, produces a long lasting suppression of excessive alcohol consumption in rats. GDNF drug alcohol 22238721 Here we determined whether GDNF activates a positive autoregulatory feedback loop in vivo within the VTA, and if so, whether this mechanism underlies the long lasting suppressive effects of the growth factor on excessive alcohol consumption. GDNF drug alcohol 22238721 Importantly, we report that the GDNF mediated positive autoregulatory feedback loop accounts for the long lasting inhibitory actions of GDNF in the VTA on excessive alcohol consumption. GDNF drug alcohol 22238721 Specifically, the long lasting suppressive effects of a single rGDNF infusion into the VTA on excessive alcohol consumption were prevented when protein synthesis was inhibited, as well as when the upregulation of GDNF expression was prevented using short hairpin RNA to focally knock down GDNF mRNA in the VTA. GDNF addiction addiction 22238721 Our results could have implications for the development of long lasting treatments for disorders in which GDNF has a beneficial role, including drug addiction, chronic stress and Parkinson's disease.

GDNF drug alcohol 21734280 We previously showed that infusion of glial cell line derived neurotrophic factor (GDNF) into the ventral tegmental area (VTA) rapidly reduces alcohol intake and relapse (Carnicella et al., 2008, 2009a), and increases dopamine (DA) levels in the nucleus accumbens (NAc) of alcohol naive rats (Wang et al., 2010). GDNF addiction relapse 21734280 We previously showed that infusion of glial cell line derived neurotrophic factor (GDNF) into the ventral tegmental area (VTA) rapidly reduces alcohol intake and relapse (Carnicella et al., 2008, 2009a), and increases dopamine (DA) levels in the nucleus accumbens (NAc) of alcohol naive rats (Wang et al., 2010). GDNF drug alcohol 21734280 We therefore tested whether GDNF in the VTA reverses alcohol withdrawal associated DA deficiency and/or possesses rewarding properties. GDNF addiction withdrawal 21734280 We therefore tested whether GDNF in the VTA reverses alcohol withdrawal associated DA deficiency and/or possesses rewarding properties. GDNF drug alcohol 21734280 Using in vivo microdialysis, we show that 24 h withdrawal from alcohol causes a substantial reduction in NAc DA overflow, which was reversed by intra VTA GDNF infusion. GDNF addiction withdrawal 21734280 Using in vivo microdialysis, we show that 24 h withdrawal from alcohol causes a substantial reduction in NAc DA overflow, which was reversed by intra VTA GDNF infusion. GDNF addiction reward 21734280 Using conditioned place preference (CPP) paradigm, we observed that GDNF on its own does not induce CPP, suggesting that the growth factor is not rewarding.

GDNF drug cocaine 21182575 Glial cell line derived neurotrophic factor (GDNF) activity in ventral tegmental area (VTA) mediates the time dependent increases in cue induced cocaine seeking after withdrawal (incubation of cocaine craving). GDNF addiction relapse 21182575 Glial cell line derived neurotrophic factor (GDNF) activity in ventral tegmental area (VTA) mediates the time dependent increases in cue induced cocaine seeking after withdrawal (incubation of cocaine craving). GDNF addiction withdrawal 21182575 Glial cell line derived neurotrophic factor (GDNF) activity in ventral tegmental area (VTA) mediates the time dependent increases in cue induced cocaine seeking after withdrawal (incubation of cocaine craving). GDNF drug opioid 21182575 Cue induced heroin seeking was higher after 11 or 30 days than after 1 day (incubation of heroin craving), and the time dependent increases in extinction responding were associated with time dependent changes in GDNF mRNA expression in VTA and nucleus accumbens. GDNF addiction relapse 21182575 Cue induced heroin seeking was higher after 11 or 30 days than after 1 day (incubation of heroin craving), and the time dependent increases in extinction responding were associated with time dependent changes in GDNF mRNA expression in VTA and nucleus accumbens. GDNF drug opioid 21182575 Additionally, acute accumbens (but not VTA) GDNF injections (12.5 µg/side) administered 1 3 hours after the last heroin self administration training session enhanced the time dependent increases in extinction responding after withdrawal. GDNF addiction withdrawal 21182575 Additionally, acute accumbens (but not VTA) GDNF injections (12.5 µg/side) administered 1 3 hours after the last heroin self administration training session enhanced the time dependent increases in extinction responding after withdrawal. GDNF addiction withdrawal 21182575 However, the time dependent increases in extinction responding after withdrawal were not associated with changes in GDNF protein expression in VTA and accumbens. GDNF drug opioid 21182575 In summary, heroin self administration and withdrawal regulate VTA and accumbens GDNF mRNA expression in a time dependent manner, and exogenous GDNF administration into accumbens but not VTA potentiates cue induced heroin seeking. GDNF addiction relapse 21182575 In summary, heroin self administration and withdrawal regulate VTA and accumbens GDNF mRNA expression in a time dependent manner, and exogenous GDNF administration into accumbens but not VTA potentiates cue induced heroin seeking.

GDNF drug psychedelics 21040239 Noribogaine, but not 18 MC, exhibits similar actions as ibogaine on GDNF expression and ethanol self administration. GDNF drug alcohol 21040239 Previously, we reported that the desirable actions of ibogaine to reduce self administration of, and relapse to, alcohol consumption are mediated via the upregulation of the expression of the glial cell line derived neurotrophic factor (GDNF) in the midbrain ventral tegmental area (VTA), and the consequent activation of the GDNF pathway.

GDNF drug alcohol 21040239 Here, we determined whether noribogaine and/or 18 MC, like ibogaine, increase GDNF expression, and whether their site of action to reduce alcohol consumption is the VTA. GDNF drug psychedelics 21040239 Here, we determined whether noribogaine and/or 18 MC, like ibogaine, increase GDNF expression, and whether their site of action to reduce alcohol consumption is the VTA. GDNF drug psychedelics 21040239 We used SH SY5Y cells as a cell culture model and found that noribogaine, like ibogaine, but not 18 MC, induces a robust increase in GDNF mRNA levels.

GDNF drug cocaine 19345340 Additionally, VTA, but not substantial nigra (SN), GDNF injections (1.25 microg or 12.5 microg/side) immediately after the last cocaine self administration session increased cue induced drug seeking on withdrawal days 3 and 10; this effect was reversed by VTA injections of U0126, which inhibits the activity of extracellular signal regulated kinases (ERK).

GDNF drug alcohol 19302086 GDNF is an endogenous negative regulator of ethanol mediated reward and of ethanol consumption after a period of abstinence. GDNF addiction reward 19302086 GDNF is an endogenous negative regulator of ethanol mediated reward and of ethanol consumption after a period of abstinence. GDNF drug alcohol 19302086 We previously found that activation of the glial cell line derived neurotrophic factor (GDNF) pathway in the ventral tegmental area (VTA) reduces ethanol drinking behaviors. GDNF drug alcohol 19302086 In this study, we set out to assess the contribution of endogenous GDNF or its receptor GFRalpha1 to the regulation of ethanol related behaviors. GDNF drug alcohol 19302086 We observed no differences between the GDNF HET and WT mice in the level of locomotor activity or in sensitization to ethanol induced hyperlocomotion after systemic injection of a nonhypnotic dose of ethanol and in BEC. GDNF addiction sensitization 19302086 We observed no differences between the GDNF HET and WT mice in the level of locomotor activity or in sensitization to ethanol induced hyperlocomotion after systemic injection of a nonhypnotic dose of ethanol and in BEC. GDNF drug alcohol 19302086 However, GDNF and GFRalpha1 mice exhibited increased place preference to ethanol as compared with their WT littermates. GDNF drug alcohol 19302086 The levels of voluntary ethanol or quinine consumption were similar in the GDNF HET and WT mice, however, a small but significant increase in saccharin intake was observed in the GDNF HET mice. GDNF drug alcohol 19302086 Interestingly, however, both the GDNF and GFRalpha1 HET mice consumed much larger quantities of ethanol after a period of abstinence from ethanol as compared with their WT littermates. GDNF drug alcohol 19302086 Furthermore, the increase in ethanol consumption after abstinence was found to be specific for ethanol as similar levels of saccharin intake were measured in the GDNF and GFRalpha1 HET and WT mice after abstinence. GDNF drug alcohol 19302086 Our results suggest that endogenous GDNF negatively regulates the rewarding effect of ethanol and ethanol drinking behaviors after a period of abstinence. GDNF drug alcohol 19232578 We recently showed that GDNF in the ventral tegmental area (VTA) reduces the motivation to consume alcohol. GDNF drug alcohol 19232578 We therefore set out to determine whether cabergoline administration decreases alcohol drinking and seeking behaviors via GDNF. GDNF addiction relapse 19232578 We therefore set out to determine whether cabergoline administration decreases alcohol drinking and seeking behaviors via GDNF. GDNF drug alcohol 19232578 Finally, the increase in GDNF expression and the decrease in alcohol consumption by cabergoline were abolished in GDNF heterozygous knockout mice. GDNF drug alcohol 19232578 Together, these findings suggest that cabergoline mediated upregulation of the GDNF pathway attenuates alcohol drinking behaviors and relapse. GDNF addiction relapse 19232578 Together, these findings suggest that cabergoline mediated upregulation of the GDNF pathway attenuates alcohol drinking behaviors and relapse. GDNF drug alcohol 19185208 We previously found that activation of the glial cell line derived neurotrophic factor (GDNF) pathway in the ventral tegmental area (VTA) reduces moderate alcohol (ethanol) intake in a rat operant self administration paradigm. GDNF addiction reward 19185208 We previously found that activation of the glial cell line derived neurotrophic factor (GDNF) pathway in the ventral tegmental area (VTA) reduces moderate alcohol (ethanol) intake in a rat operant self administration paradigm. GDNF drug alcohol 19185208 Here, we set out to assess the effect of GDNF in the VTA on excessive voluntary consumption of ethanol. GDNF drug alcohol 19185208 The rats were given three 24 h sessions per week, and GDNF's actions were measured when rats achieved a baseline of ethanol consumption of 5.5g/kg/24h. GDNF drug alcohol 19185208 We found that microinjection of GDNF into the VTA 10min before the beginning of an ethanol drinking session significantly reduced ethanol intake and preference, but did not affect total fluid intake. GDNF drug alcohol 19185208 We further show that GDNF greatly decreased both the first bout of excessive ethanol intake at the beginning of the session, and the later consummatory activity occurring during the dark cycle. GDNF drug alcohol 19185208 These data suggest that GDNF is a rapid and long lasting inhibitor of "binge like" ethanol consumption. GDNF addiction intoxication 19185208 These data suggest that GDNF is a rapid and long lasting inhibitor of "binge like" ethanol consumption. GDNF drug amphetamine 19110059 Minocycline restores striatal tyrosine hydroxylase in GDNF heterozygous mice but not in methamphetamine treated mice. GDNF drug amphetamine 19110059 Microglial activation in the substantia nigra and a tyrosine hydroxylase deficit in the striatum of 3 month old GDNF heterozygous (GDNF(+/ )) mice were previously reported and both were exacerbated by a toxic methamphetamine binge. GDNF addiction intoxication 19110059 Microglial activation in the substantia nigra and a tyrosine hydroxylase deficit in the striatum of 3 month old GDNF heterozygous (GDNF(+/ )) mice were previously reported and both were exacerbated by a toxic methamphetamine binge. GDNF drug amphetamine 19110059 Minocycline (45 mg/kg, i.p.x 14 days post methamphetamine or saline injections) reduced microglial activation and phospho p38 MAPK in the substantia nigra of saline treated GDNF(+/ ) mice and in methamphetamine treated wildtype and GDNF(+/ ) mice. GDNF drug amphetamine 19110059 Although minocycline increased tyrosine hydroxylase immunoreactivity in GDNF(+/ ) mice, it did not attenuate the methamphetamine induced reduction of tyrosine hydroxylase. GDNF drug amphetamine 19110059 The results suggest that neuroinflammation is deleterious to the dopamine system of GDNF(+/ ) mice but is not the primary cause of methamphetamine induced damage to the dopamine system in either GDNF(+/ ) or wildtype mice. GDNF drug alcohol 18541917 GDNF is a fast acting potent inhibitor of alcohol consumption and relapse. GDNF addiction relapse 18541917 GDNF is a fast acting potent inhibitor of alcohol consumption and relapse. GDNF drug alcohol 18541917 Previously, we demonstrated that the action of the natural alkaloid, ibogaine, to reduce alcohol (ethanol) consumption is mediated by the glial cell line derived neurotrophic factor (GDNF) in the ventral tegmental area (VTA). GDNF drug psychedelics 18541917 Previously, we demonstrated that the action of the natural alkaloid, ibogaine, to reduce alcohol (ethanol) consumption is mediated by the glial cell line derived neurotrophic factor (GDNF) in the ventral tegmental area (VTA). GDNF drug alcohol 18541917 Here we set out to test the actions of GDNF in the VTA on ethanol drinking behaviors. GDNF drug alcohol 18541917 We found that GDNF infusion very rapidly and dose dependently reduced rat ethanol, but not sucrose, operant self administration. GDNF addiction reward 18541917 We found that GDNF infusion very rapidly and dose dependently reduced rat ethanol, but not sucrose, operant self administration. GDNF drug alcohol 18541917 A GDNF mediated decrease in ethanol consumption was also observed in rats with a history of high voluntary ethanol intake. GDNF drug alcohol 18541917 We found that the action of GDNF on ethanol consumption was specific to the VTA as infusion of the growth factor into the neighboring substantia nigra did not affect operant responses for ethanol. GDNF addiction reward 18541917 We found that the action of GDNF on ethanol consumption was specific to the VTA as infusion of the growth factor into the neighboring substantia nigra did not affect operant responses for ethanol. GDNF drug alcohol 18541917 We further show that intra VTA GDNF administration rapidly activated the MAPK signaling pathway in the VTA and that inhibition of the MAPK pathway in the VTA blocked the reduction of ethanol self administration by GDNF. GDNF addiction relapse 18541917 Importantly, we demonstrate that GDNF infused into the VTA alters rats' responses in a model of relapse. GDNF drug alcohol 18541917 Specifically, GDNF application blocked reacquisition of ethanol self administration after extinction. GDNF drug alcohol 18541917 Together, these results suggest that GDNF, via activation of the MAPK pathway, is a fast acting selective agent to reduce the motivation to consume and seek alcohol. GDNF drug amphetamine 17699663 Administration of glial cell line derived neurotrophic factor (GDNF) protects dopamine neurons from the toxic effects of methamphetamine in animal models. GDNF drug amphetamine 17699663 Therefore, we hypothesized that a partial GDNF gene deletion would increase the susceptibility of mice to methamphetamine neurotoxicity during young adulthood and possibly increase age related deterioration of behavior and dopamine function. GDNF drug amphetamine 17699663 Two weeks after a methamphetamine binge (4 x 10 mg/kg, i.p., at 2 h intervals), GDNF(+/ ) mice had a significantly greater reduction of tyrosine hydroxylase immunoreactivity in the medial striatum, a proportionally greater depletion of dopamine and 3,4 dihydroxyphenylacetic acid (DOPAC) levels in the striatum, and a greater increase in activated microglia in the substantia nigra than wild type mice. GDNF addiction intoxication 17699663 Two weeks after a methamphetamine binge (4 x 10 mg/kg, i.p., at 2 h intervals), GDNF(+/ ) mice had a significantly greater reduction of tyrosine hydroxylase immunoreactivity in the medial striatum, a proportionally greater depletion of dopamine and 3,4 dihydroxyphenylacetic acid (DOPAC) levels in the striatum, and a greater increase in activated microglia in the substantia nigra than wild type mice. GDNF drug amphetamine 17699663 At 12 months of age, methamphetamine treated GDNF(+/ ) mice exhibited less motor activity and lower levels of tyrosine hydroxylase immunoreactivity, dopamine, DOPAC, and serotonin than wild type mice. GDNF drug amphetamine 17699663 Greater striatal dopamine transporter activity in GDNF(+/ ) mice may underlie their differential response to methamphetamine. GDNF drug amphetamine 17699663 These data suggest the possibility that methamphetamine use in young adults, when combined with lower levels of GDNF throughout life, may precipitate the appearance of parkinsonian like behaviors during aging. GDNF addiction dependence 17538232 In this article, the roles of glial cell line derived neurotrophic factor (GDNF) and tumor necrosis factor alpha (TNF alpha) in drug dependence are discussed. GDNF drug cocaine 17538232 GDNF inhibits the cocaine induced upregulation of tyrosine hydroxylase activity in the ventral tegmental area and blocks behavioral responses to cocaine. GDNF addiction dependence 17538232 Moreover, we mentioned the potential of Leu Ile, which induces the expression of GDNF and TNF alpha, as a novel therapeutic agent for drug dependence. GDNF drug amphetamine 17538232 The inhibitory effect of Leu Ile on METH or MOR induced place preference is not observed in GDNF heterozygous and TNF alpha knockout mice. GDNF drug amphetamine 17538232 Leu Ile inhibits METH or MOR induced place preference and sensitization by attenuating the METH or MOR induced increase in extracellular dopamine levels in the nucleus accumbens via the induction of GDNF and TNF alpha expression. GDNF addiction sensitization 17538232 Leu Ile inhibits METH or MOR induced place preference and sensitization by attenuating the METH or MOR induced increase in extracellular dopamine levels in the nucleus accumbens via the induction of GDNF and TNF alpha expression. GDNF drug amphetamine 17356005 Using a mouse model of reinstatement, which models relapse of drug seeking behavior in addicts, we provide evidence that a partial reduction in the expression of the glial cell line derived neurotrophic factor (GDNF) potentiates methamphetamine (METH) self administration, enhances motivation to take METH, increases vulnerability to drug primed reinstatement, and prolongs cue induced reinstatement of extinguished METH seeking behavior. GDNF addiction relapse 17356005 Using a mouse model of reinstatement, which models relapse of drug seeking behavior in addicts, we provide evidence that a partial reduction in the expression of the glial cell line derived neurotrophic factor (GDNF) potentiates methamphetamine (METH) self administration, enhances motivation to take METH, increases vulnerability to drug primed reinstatement, and prolongs cue induced reinstatement of extinguished METH seeking behavior. GDNF drug amphetamine 17356005 In contrast, there was no significant difference in novelty responses, METH stimulated hyperlocomotion and locomotor sensitization, food reinforced operant behavior and motivation, or reinstatement of food seeking behavior between GDNF heterozygous knockout mice and wild type littermates. GDNF addiction relapse 17356005 In contrast, there was no significant difference in novelty responses, METH stimulated hyperlocomotion and locomotor sensitization, food reinforced operant behavior and motivation, or reinstatement of food seeking behavior between GDNF heterozygous knockout mice and wild type littermates.

GDNF drug amphetamine 17356005 These findings suggest that GDNF may be associated with enduring vulnerability to reinstatement of METH seeking behavior and a potential target in the development of therapies to control relapse. GDNF addiction relapse 17356005 These findings suggest that GDNF may be associated with enduring vulnerability to reinstatement of METH seeking behavior and a potential target in the development of therapies to control relapse. GDNF drug amphetamine 17331595 We have previously demonstrated that Leu Ile, which induces the expression of not only tumor necrosis factor alpha (TNF alpha) but also glial cell line derived neurotrophic factor (GDNF), inhibits methamphetamine (METH) and morphine (MOR) induced sensitization and rewarding effects by regulating extracellular dopamine levels via the induction of TNF alpha expression, and indicated the potential of Leu Ile as a novel therapeutic agent for METH and MOR induced dependence. GDNF drug opioid 17331595 We have previously demonstrated that Leu Ile, which induces the expression of not only tumor necrosis factor alpha (TNF alpha) but also glial cell line derived neurotrophic factor (GDNF), inhibits methamphetamine (METH) and morphine (MOR) induced sensitization and rewarding effects by regulating extracellular dopamine levels via the induction of TNF alpha expression, and indicated the potential of Leu Ile as a novel therapeutic agent for METH and MOR induced dependence. GDNF addiction dependence 17331595 We have previously demonstrated that Leu Ile, which induces the expression of not only tumor necrosis factor alpha (TNF alpha) but also glial cell line derived neurotrophic factor (GDNF), inhibits methamphetamine (METH) and morphine (MOR) induced sensitization and rewarding effects by regulating extracellular dopamine levels via the induction of TNF alpha expression, and indicated the potential of Leu Ile as a novel therapeutic agent for METH and MOR induced dependence.

GDNF addiction sensitization 17331595 In the present study, we investigated the involvement of GDNF in inhibitory effects of Leu Ile on MOR induced sensitization and rewarding effects. GDNF addiction sensitization 17331595 Repeated treatment with MOR for 9 days, which results in an enhancement of the locomotor stimulating effects (sensitization) of MOR, increased GDNF levels in the nucleus accumbens compared with those in saline treated mice. GDNF addiction sensitization 17331595 These results suggest that GDNF is involved in the inhibitory effects of Leu Ile on MOR induced sensitization and rewarding effects. GDNF drug amphetamine 17046726 We investigated the potential of Leu Ile, which induces the expression of glial cell line derived neurotrophic factor (GDNF) and tumor necrosis factor alpha (TNF alpha), as a novel therapeutic agent for methamphetamine (METH) induced dependence. GDNF addiction dependence 17046726 We investigated the potential of Leu Ile, which induces the expression of glial cell line derived neurotrophic factor (GDNF) and tumor necrosis factor alpha (TNF alpha), as a novel therapeutic agent for methamphetamine (METH) induced dependence. GDNF drug amphetamine 17046726 An inhibitory effect of Leu Ile on METH induced place preference was observed in neither GDNF heterozygous nor TNF alpha knockout mice. GDNF drug amphetamine 17046726 These results suggest that Leu Ile inhibits METH induced rewarding effects and sensitization by regulating extracellular DA levels via the induction of GDNF and TNF alpha expression. GDNF addiction sensitization 17046726 These results suggest that Leu Ile inhibits METH induced rewarding effects and sensitization by regulating extracellular DA levels via the induction of GDNF and TNF alpha expression. GDNF drug alcohol 17023388 We recently showed that the up regulation of the glial cell line derived neurotrophic factor (GDNF) pathway in the midbrain, is the molecular mechanism by which the putative anti addiction drug Ibogaine mediates its desirable action of reducing alcohol consumption. GDNF drug psychedelics 17023388 We recently showed that the up regulation of the glial cell line derived neurotrophic factor (GDNF) pathway in the midbrain, is the molecular mechanism by which the putative anti addiction drug Ibogaine mediates its desirable action of reducing alcohol consumption. GDNF addiction addiction 17023388 We recently showed that the up regulation of the glial cell line derived neurotrophic factor (GDNF) pathway in the midbrain, is the molecular mechanism by which the putative anti addiction drug Ibogaine mediates its desirable action of reducing alcohol consumption. GDNF drug psychedelics 17023388 Here we determine whether, and how, Ibogaine exerts its long lasting actions on GDNF expression and signaling. GDNF drug psychedelics 17023388 Using the dopaminergic like SHSY5Y cell line as a culture model, we observed that short term Ibogaine exposure results in a sustained increase in GDNF expression that is mediated via the induction of a long lasting autoregulatory cycle by which GDNF positively regulates its own expression. GDNF drug psychedelics 17023388 We show that the initial exposure of cells to Ibogaine or GDNF results in an increase in GDNF mRNA, leading to protein expression and to the corresponding activation of the GDNF signaling pathway. GDNF addiction addiction 17023388 The identification of a GDNF mediated, autoregulatory long lasting feedback loop could have important implications for GDNF's potential value as a treatment for addiction and neurodegenerative diseases. GDNF drug opioid 16879618 To study the effects of reduced GDNF on dopaminergic behaviour related to addiction, we compared the effects of morphine on locomotor activity, conditioned place preference (CPP) and extracellular accumbal dopamine in heterozygous GDNF knockout mice (GDNF+/ ) with those in their wild type (Wt) littermates. GDNF addiction addiction 16879618 To study the effects of reduced GDNF on dopaminergic behaviour related to addiction, we compared the effects of morphine on locomotor activity, conditioned place preference (CPP) and extracellular accumbal dopamine in heterozygous GDNF knockout mice (GDNF+/ ) with those in their wild type (Wt) littermates. GDNF addiction reward 16879618 To study the effects of reduced GDNF on dopaminergic behaviour related to addiction, we compared the effects of morphine on locomotor activity, conditioned place preference (CPP) and extracellular accumbal dopamine in heterozygous GDNF knockout mice (GDNF+/ ) with those in their wild type (Wt) littermates. GDNF drug opioid 16879618 When morphine 30 mg/kg was administered daily for 4 days, tolerance developed towards its locomotor stimulatory action only in the GDNF+/ mice. GDNF drug opioid 16879618 A morphine 5 mg/kg challenge dose stimulated locomotor activity only in the GDNF+/ mice withdrawn for 96 h from repeated morphine treatment, whereas clear and similar sensitization of the locomotor response was seen after a 10 mg/kg challenge dose in mice of both genotypes. GDNF addiction sensitization 16879618 A morphine 5 mg/kg challenge dose stimulated locomotor activity only in the GDNF+/ mice withdrawn for 96 h from repeated morphine treatment, whereas clear and similar sensitization of the locomotor response was seen after a 10 mg/kg challenge dose in mice of both genotypes. GDNF drug opioid 16879618 Morphine induced CPP developed initially similarly in Wt and GDNF+/ mice, but it lasted longer in the Wt mice. GDNF addiction reward 16879618 Morphine induced CPP developed initially similarly in Wt and GDNF+/ mice, but it lasted longer in the Wt mice. GDNF drug opioid 16879618 The small challenge dose of morphine increased accumbal dopamine output slightly more in the GDNF+/ mice than in the Wt mice, but doubling the challenge dose caused a dose dependent response only in the Wt mice. GDNF drug opioid 16879618 In addition, repeated morphine treatment counteracted the increase in the accumbal extracellular dopamine concentration we previously found in drug naive GDNF+/ mice. GDNF drug opioid 16879618 Thus, reduced endogenous GDNF level alters the dopaminergic behavioural effects to repeatedly administered morphine, emphasizing the involvement of GDNF in the neuroplastic changes related to long term effects of drugs of abuse. GDNF addiction addiction 16519005 GDNF and addiction. GDNF drug alcohol 16519005 Behavioral effects of drugs of abuse such as cocaine and alcohol are also negatively regulated by GDNF: inhibition of the endogenous GDNF pathway enhances the activity of drugs of abuse, while administration of GDNF reduces the severity of the effects. GDNF drug cocaine 16519005 Behavioral effects of drugs of abuse such as cocaine and alcohol are also negatively regulated by GDNF: inhibition of the endogenous GDNF pathway enhances the activity of drugs of abuse, while administration of GDNF reduces the severity of the effects.

GDNF addiction addiction 16441270 BIG news in alcohol addiction: new findings on growth factor pathways BDNF, insulin, and GDNF. GDNF drug alcohol 16441270 The 4 speakers showed that the behavioral effects of alcohol in the adult are regulated by 3 growth factors, insulin, glial cell line derived neurotrophic factor (GDNF), and brain derived neurotrophic factor (BDNF). GDNF drug alcohol 16441270 Finally, Dr. Janak presented evidence that increases in the expression of GDNF in the midbrain reduce alcohol self administration in rats.

GDNF drug alcohol 16364262 Glial cell line derived neurotrophic factor (GDNF) has been reported to alter the reward value of abused substances such as alcohol and cocaine as well as neural circuitry underlying reward. GDNF drug cocaine 16364262 Glial cell line derived neurotrophic factor (GDNF) has been reported to alter the reward value of abused substances such as alcohol and cocaine as well as neural circuitry underlying reward. GDNF addiction reward 16364262 Glial cell line derived neurotrophic factor (GDNF) has been reported to alter the reward value of abused substances such as alcohol and cocaine as well as neural circuitry underlying reward. GDNF addiction reward 16364262 The role of GDNF in reward was further characterized in the present study using operant procedures to determine the value of a natural reward, sucrose, in GDNF heterozygous (GDNF+/ ) mice versus wild type (WT) mice. GDNF addiction reward 16364262 GDNF+/ mice emitted more responses than WT mice for sucrose, suggesting enhanced reward value of sucrose in these mice. GDNF addiction reward 16364262 Together, the results are consistent with an emerging literature indicating that reduced GDNF levels augment reward and increased GDNF levels attenuate reward, suggesting that GDNF plays an important role in neural systems mediating reward.

PPP1R1B drug opioid 17251906 Here, we show that, in the mouse nucleus accumbens and dorsal striatum, acute administration of morphine resulted in an increase in the state of phosphorylation of the dopamine and cAMP regulated phosphoprotein of 32 kDa (DARPP 32) at Thr34, without affecting phosphorylation at Thr75.

PPP1R1B drug nicotine 16084497 DARPP 32 phosphorylation opposes the behavioral effects of nicotine. PPP1R1B drug nicotine 16084497 Because post synaptic neurons within the striatum contain high levels of the dopamine and cAMP regulated phosphoprotein of 32 kDa (DARPP 32), we hypothesized that DARPP 32 may functionally contribute to the behavioral effects of nicotine.

PPP1R1B drug cocaine 15536496 The cyclin dependent kinase Cdk5 and DARPP 32 (dopamine and cAMP regulated phosphoprotein of Mr 32 kDa) dependent signaling have been implicated in the regulation of dopaminergic neurotransmission after chronic cocaine treatment. PPP1R1B drug amphetamine 15536496 The phosphorylation of DARPP 32 at both Thr75 and Thr34 was differentially regulated after acute METH treatment, but the levels of total Cdk5, p35, and DARPP 32 remained the same.

HOMER1 drug cocaine 29163080 Earlier studies of Homer1 gene knock out (KO) mice indicated active, but distinct, roles for IEG and constitutively expressed Homer1 gene products in regulating cognitive, emotional, motivational and sensorimotor processing, as well as behavioral and neurochemical sensitivity to cocaine. HOMER1 drug cocaine 29163080 More recent characterization of transgenic mice engineered to prevent generation of the IEG form (a.k.a Homer1a KO) pose a critical role for Homer1a in cocaine induced behavioral and neurochemical sensitization of relevance to drug addiction and related neuropsychiatric disorders.

HOMER1 addiction sensitization 29163080 More recent characterization of transgenic mice engineered to prevent generation of the IEG form (a.k.a Homer1a KO) pose a critical role for Homer1a in cocaine induced behavioral and neurochemical sensitization of relevance to drug addiction and related neuropsychiatric disorders. HOMER1 drug cocaine 29163080 Here, we extend our characterization of the Homer1a KO mouse and report a modest pro depressant phenotype, but no deleterious effects of the KO upon spatial learning/memory, prepulse inhibition, or cocaine induced place conditioning. HOMER1 drug cocaine 29163080 As we reported previously, Homer1a KO mice did not develop cocaine induced behavioral or neurochemical sensitization within the nucleus accumbens; however, virus mediated Homer1a over expression within the nucleus accumbens reversed the sensitization phenotype of KO mice. HOMER1 addiction sensitization 29163080 As we reported previously, Homer1a KO mice did not develop cocaine induced behavioral or neurochemical sensitization within the nucleus accumbens; however, virus mediated Homer1a over expression within the nucleus accumbens reversed the sensitization phenotype of KO mice. HOMER1 drug cocaine 29163080 Moreover, the data indicate a specific role for Homer1a in regulating cocaine induced behavioral and neurochemical sensitization of potential relevance to the psychotogenic properties of this drug.

HOMER1 drug cocaine 29055697 Cocaine alters Homer1 natural antisense transcript in the nucleus accumbens. HOMER1 drug cocaine 29055697 We found that 22% of the genes examined contain NATs and that expression of Homer1 natural antisense transcript (Homer1 AS) was altered in the nucleus accumbens (NAc) of mice 2h and 10days following repeated cocaine administration. HOMER1 drug cocaine 29055697 Future in vivo studies are needed to definitely determine a role for Homer1 AS in cocaine induced behavioral and molecular adaptations. HOMER1 drug alcohol 27180911 However, genetic variations in ANKK1 (rs1800497) and HOMER1 (rs7713917) play an equal role in predicting alcohol drinking two years later and are most important in predicting the increase in alcohol consumption. HOMER1 drug alcohol 26791202 mTORC1 is critically involved in RNA to protein translation, and we found that the first alcohol session rapidly activated mTORC1 in NAc shell D1+ neurons and increased synaptic expression of the AMPAR subunit GluA1 and the scaffolding protein Homer. HOMER1 drug cocaine 26598422 Increased expression after cocaine self administration was found for 6 IEGs in dorsal and ventral striatum (c fos, Mkp1, Fosb/ΔFosb, Egr2, Egr4, and Arc) and 10 IEGs in mPFC (same 6 IEGs as in striatum, plus Bdnf, Homer1, Sgk1 and Rgs2). HOMER1 drug alcohol 25743187 In the medial prefrontal cortex, 2.5g/kg ethanol decreased mRNA expression of brain derived neurotrophic factor, NMDA NR2A subunit, mGluR8 receptor, Homer1, the glutamate transporters SLC1a1 and SLC1a6 and Srr. HOMER1 drug cocaine 25530939 Thus, we measured the effects of a 6 day repeated treatment with methylphenidate (5 mg/kg), fluoxetine (5 mg/kg) or their combination on the inducibility (by cocaine) of neuroplasticity related IEGs (Zif268, Homer1a) in the striatum, by in situ hybridization histochemistry. HOMER1 drug cocaine 25408547 Our results showed that both contingent and non contingent cocaine administration produces numerous, brain region specific, alterations in the mGluR(5), NMDA, and Homer1b/1c protein expression which are dependent on the modality of cocaine administration. HOMER1 drug cocaine 24118426 Cocaine elicited imbalances in ventromedial prefrontal cortex Homer1 versus Homer2 expression: implications for relapse. HOMER1 addiction relapse 24118426 Cocaine elicited imbalances in ventromedial prefrontal cortex Homer1 versus Homer2 expression: implications for relapse. HOMER1 drug cocaine 24118426 Withdrawal from a history of extended access to self administered cocaine produces a time dependent intensification of drug seeking, which might relate to a cocaine induced imbalance in the relative expression of constitutively expressed Homer1 versus Homer2 isoforms within the ventromedial aspect of the prefrontal cortex (vmPFC). HOMER1 addiction relapse 24118426 Withdrawal from a history of extended access to self administered cocaine produces a time dependent intensification of drug seeking, which might relate to a cocaine induced imbalance in the relative expression of constitutively expressed Homer1 versus Homer2 isoforms within the ventromedial aspect of the prefrontal cortex (vmPFC).

HOMER1 drug cocaine 24118426 Thus, we employed immunoblotting to examine the relation between cue reinforced lever pressing at 3 versus 30 day withdrawal from a 10 day history of extended access (6 hours/day) to intravenous cocaine (0.25 mg/infusion) or saline (Sal6h), and the expression of Homer1b/c and Homer2a/b within the vmPFC versus the more dorsomedial aspect of this structure (dmPFC). HOMER1 addiction withdrawal 24118426 Thus, we employed immunoblotting to examine the relation between cue reinforced lever pressing at 3 versus 30 day withdrawal from a 10 day history of extended access (6 hours/day) to intravenous cocaine (0.25 mg/infusion) or saline (Sal6h), and the expression of Homer1b/c and Homer2a/b within the vmPFC versus the more dorsomedial aspect of this structure (dmPFC). HOMER1 drug cocaine 24118426 Behavioral studies employed adeno associated virus (AAV) vectors to reverse cocaine elicited changes in the relative expression of Homer1 versus Homer2 isoforms and tested animals for cocaine prime , and cue induced responding following extinction training. HOMER1 drug cocaine 24118426 Cocaine self administration elevated both Homer1b/c and Homer2a/b levels within the vmPFC at 3 day withdrawal, and the rise in Homer2a/b persisted for at least 30 days. HOMER1 addiction withdrawal 24118426 Cocaine self administration elevated both Homer1b/c and Homer2a/b levels within the vmPFC at 3 day withdrawal, and the rise in Homer2a/b persisted for at least 30 days. HOMER1 drug cocaine 24118426 Reversing the relative increase in Homer2 versus Homer1 expression via Homer1c overexpression or Homer2b knockdown failed to influence cue reinforced lever pressing when animals were tested in a drug free state, but both AAV treatments prevented cocaine primed reinstatement of lever pressing behavior. HOMER1 addiction relapse 24118426 Reversing the relative increase in Homer2 versus Homer1 expression via Homer1c overexpression or Homer2b knockdown failed to influence cue reinforced lever pressing when animals were tested in a drug free state, but both AAV treatments prevented cocaine primed reinstatement of lever pressing behavior.

HOMER1 drug cocaine 24118426 These data suggest that a cocaine elicited imbalance in the relative expression of constitutively expressed Homer2 versus Homer1 within the vmPFC is necessary for the capacity of cocaine to reinstate drug seeking behavior, posing drug induced changes in vmPFC Homer expression as a molecular trigger contributing to drug elicited relapse.

HOMER1 drug amphetamine 23895375 Methamphetamine induced 3 20 fold increases of immediate early genes arc, homer 2, c fos, fosB, and its isoforms (ΔfosB and a novel isoform ΔfosB 2) in Fos positive but not Fos negative neurons. HOMER1 drug cocaine 23763573 We measured, by in situ hybridization histochemistry, the effects of a 5 day repeated treatment with methylphenidate (5 mg/kg), fluoxetine (5 mg/kg) or a combination on the inducibility (by cocaine) of neuroplasticity related genes (Zif268, Homer1a) in the striatum. HOMER1 addiction addiction 23761764 Homer proteins, and their associated glutamate receptors, regulate behavioral sensitivity to various addictive drugs. HOMER1 drug opioid 23761764 Null mutations of Homer1a, Homer1, and Homer2, as well as transgenic disruption of mGluR5 Homer interactions, either attenuated or completely blocked low dose heroin CPP, and none of the CCI mutant strains exhibited heroin induced CPA.

HOMER1 addiction reward 23761764 Null mutations of Homer1a, Homer1, and Homer2, as well as transgenic disruption of mGluR5 Homer interactions, either attenuated or completely blocked low dose heroin CPP, and none of the CCI mutant strains exhibited heroin induced CPA. HOMER1 drug opioid 23761764 However, heroin CPP did not depend upon full Homer1c expression within the nucleus accumbens (NAC), as CPP occurred in controls infused locally with small hairpin RNA Homer1c, although intra NAC and/or intrathecal cDNA Homer1c, Homer1a, and Homer2b infusions (to best mimic CCI's effects) were sufficient to blunt heroin CPP in uninjured mice.

HOMER1 drug opioid 23761764 However, arguing against a simple role for CCI induced increases in either spinal or NAC Homer expression for heroin CPA, cDNA infusion of our various cDNA constructs either did not affect (intrathecal) or attenuated (NAC) heroin CPA. HOMER1 drug opioid 23761764 Together, these data implicate increases in glutamate receptor/Homer/kinase activity within limbic structures, perhaps outside the NAC, as possibly critical for switching the incentive motivational properties of heroin following nerve injury, which has relevance for opioid psychopharmacology in individuals suffering from neuropathic pain.

HOMER1 drug cocaine 23658151 Imbalances in prefrontal cortex CC Homer1 versus CC Homer2 expression promote cocaine preference. HOMER1 addiction addiction 23658151 Homer postsynaptic scaffolding proteins regulate forebrain glutamate transmission and thus, are likely molecular candidates mediating hypofrontality in addiction. HOMER1 drug cocaine 23658151 Protracted withdrawal from cocaine experience increases the relative expression of Homer2 versus Homer1 isoforms within medial prefrontal cortex (mPFC). HOMER1 addiction withdrawal 23658151 Protracted withdrawal from cocaine experience increases the relative expression of Homer2 versus Homer1 isoforms within medial prefrontal cortex (mPFC). HOMER1 drug cocaine 23658151 In contrast, elevating the relative expression of Homer2b versus Homer1 within mPFC, by overexpressing Homer2b or knocking down Homer1c, shifted the dose response function for cocaine conditioned reward to the left, without affecting cocaine locomotion or sensitization. HOMER1 addiction reward 23658151 In contrast, elevating the relative expression of Homer2b versus Homer1 within mPFC, by overexpressing Homer2b or knocking down Homer1c, shifted the dose response function for cocaine conditioned reward to the left, without affecting cocaine locomotion or sensitization.

HOMER1 drug cocaine 23658151 Intriguingly, both these transgenic manipulations produced glutamate anomalies within the nucleus accumbens (NAC) of cocaine naive animals that are reminiscent of those observed in cocaine experienced animals, including reduced basal extracellular glutamate content, reduced Homer1/2 and glutamate receptor expression, and augmented cocaine elicited glutamate release. HOMER1 drug cocaine 23658151 Together, these data provide novel evidence in support of opposing roles for constitutively expressed Homer1 and Homer2 isoforms in regulating mPFC glutamate transmission in vivo and support the hypothesis that cocaine elicited increases in the relative amount of mPFC Homer2 versus Homer1 signaling produces abnormalities in NAC glutamate transmission that enhance vulnerability to cocaine reward.

HOMER1 drug alcohol 22749946 Chronic self administration of ethanol reduced the expression of the C fos gene 4 to 12 fold and increased expression of the COX 2 (up to 4 fold) and Homer1a genes in the rat prefrontal cortex. HOMER1 drug alcohol 22432643 Intra NAC shell blockade of mGluR5, Homer2, or PI3K signaling, as well as transgenic disruption of the Homer binding site on mGluR5, decreased alcohol consumption in B6 mice. HOMER1 drug cocaine 22340009 Microinjecting a membrane permeable peptide antagonist of Homer binding to mGluR5 into the NAcore also inhibited cue and cocaine reinstated lever pressing. HOMER1 drug cocaine 22340009 Taken together, these data show that mGluR5 inhibition and stimulation in the NAcore can regulate cocaine seeking, and demonstrate that one mechanism for this effect is via interactions with Homer proteins.

HOMER1 drug cocaine 21126734 In line with the GluA1 PSD 95 implications of enhanced synaptic plasticity, Homer 1b/c protein expression was increased in both heroin and cocaine users as was its binding partner, dynamin 3. HOMER1 drug opioid 21126734 In line with the GluA1 PSD 95 implications of enhanced synaptic plasticity, Homer 1b/c protein expression was increased in both heroin and cocaine users as was its binding partner, dynamin 3. HOMER1 drug alcohol 21041654 We further show that the protein expression levels of GluR1 and Homer, two synaptic proteins whose translation has been shown to be modulated by mTORC1, are up regulated in the NAc of rodents with a history of excessive alcohol consumption. HOMER1 drug amphetamine 20649838 Furthermore, amphetamine but not cocaine treatment maintained the ratio between the glutamate receptor mGluR1/5 interacting proteins Homer and Homer1a in the knockouts thereby sustaining the direct pathway.

HOMER1 drug cocaine 20534846 Accordingly, when Homer1c was overexpressed in the core of cocaine naive rats with an adenoassociated virus, long term depression was inhibited. HOMER1 drug cocaine 20534846 This mechanism may contribute to the inhibition of cocaine seeking by extinction training because overexpression of Homer1c in the core also inhibited cue induced reinstatement of cocaine seeking.

HOMER1 drug alcohol 20333726 No association of alcohol dependence with HOMER 1 and 2 genetic variants. HOMER1 addiction dependence 20333726 No association of alcohol dependence with HOMER 1 and 2 genetic variants. HOMER1 drug alcohol 20333726 HOMER 1 and 2 have been reported to contribute to chronic alcohol induced long term neurochemical changes in the endogenous reward system. HOMER1 addiction reward 20333726 HOMER 1 and 2 have been reported to contribute to chronic alcohol induced long term neurochemical changes in the endogenous reward system. HOMER1 drug alcohol 20333726 Data from animal models suggest a potential role of the Homer protein family in the development of alcohol and substance use. HOMER1 drug alcohol 20333726 The aim of this study is to assess potential associations between HOMER 1 and 2 genetic variants in a larger sample of alcohol dependent individuals and unrelated controls. HOMER1 drug alcohol 20333726 Five genetic variants of HOMER 1 and 3 of HOMER 2 were genotyped in a multi site sample of 1,923 German healthy controls and 2,039 alcohol dependent subjects. HOMER1 drug alcohol 20333726 While most of the HOMER 1 and 2 SNPs are in low to moderate linkage disequilibrium, three major haplotypes of HOMER 1 and 4 haplotypes of HOMER 2 are present in the majority of alcohol dependent and control subjects. HOMER1 drug alcohol 19673743 Differential effects of chronic ethanol consumption and withdrawal on homer/glutamate receptor expression in subregions of the accumbens and amygdala of P rats. HOMER1 addiction withdrawal 19673743 Differential effects of chronic ethanol consumption and withdrawal on homer/glutamate receptor expression in subregions of the accumbens and amygdala of P rats. HOMER1 drug alcohol 19673743 In this study, we examined the effects of short versus long term withdrawal from chronic ethanol consumption on Homer and glutamate receptor protein expression within striatal and amygdala subregions of selectively bred, alcohol preferring P rats. HOMER1 addiction withdrawal 19673743 In this study, we examined the effects of short versus long term withdrawal from chronic ethanol consumption on Homer and glutamate receptor protein expression within striatal and amygdala subregions of selectively bred, alcohol preferring P rats. HOMER1 drug alcohol 19673743 Rats were killed 24 hours (short withdrawal: SW) or 4 weeks (long withdrawal: LW) after termination of ethanol access, subregions of interest were micropunched and tissue processed for detection of Group1 mGluRs, NR2 subunits of the NMDA receptor and Homer protein expression.

HOMER1 drug alcohol 19587272 Moreover, when compared with wild type littermates, transgenic mice with an F1128R point mutation in mGluR5 that markedly reduces Homer binding exhibited a 50% reduction in binge alcohol drinking, which was related to reduced NAC basal PI3K activity.

HOMER1 drug alcohol 19587272 Consistent with the hypothesis that mGluR5 Homer PI3K signaling may be a mechanism governing excessive alcohol intake, the "anti binge" effects of MPEP and wortmannin were not additive, nor were they observed in the mGluR5(F1128R) transgenic mice.

HOMER1 drug alcohol 19426165 Electroacupuncture inhibits ethanol induced locomotor sensitization and alters homer1A mRNA expression in mice. HOMER1 addiction sensitization 19426165 Electroacupuncture inhibits ethanol induced locomotor sensitization and alters homer1A mRNA expression in mice. HOMER1 drug alcohol 19426165 One hour after the challenge with ethanol, the animals were decapitated, the hippocampus, striatum, and prefrontal cortex were dissected, and the expression of homer1A mRNA assessed by PCR. HOMER1 drug alcohol 19426165 In addition, electroacupuncture blocked the diminution of homer1A mRNA expression triggered by ethanol in the acquisition (striatum and prefrontal cortex), expression (hippocampus), and in the maintenance (hippocampus and prefrontal cortex) phases. HOMER1 drug alcohol 19426165 We suggest that electroacupuncture effects over ethanol induced locomotor sensitization are associated to its ability to modulate homer1A expression and glutamatergic plasticity.

HOMER1 drug cocaine 19419424 Long lasting dysregulation of gene expression in corticostriatal circuits after repeated cocaine treatment in adult rats: effects on zif 268 and homer 1a. HOMER1 drug cocaine 19419424 We employed gene markers (zif 268 and homer 1a) that offer a high anatomical resolution to map cocaine induced changes in 22 cortical areas and 23 functionally related striatal sectors, in order to determine the corticostriatal circuits altered by repeated cocaine exposure (25 mg/kg, 5 days). HOMER1 drug cocaine 19419424 Repeated cocaine resulted in blunted inducibility of both zif 268 and homer 1a, changes that were still very robust 3 weeks later. HOMER1 drug cocaine 19306440 Extended daily access to cocaine results in distinct alterations in Homer 1b/c and NMDA receptor subunit expression within the medial prefrontal cortex. HOMER1 drug cocaine 19306440 In contrast, extended access to cocaine resulted in distinct and long lasting alterations of protein expression within the mPFC that included: increased levels of Homer1b/c at 1 day, NR2b at 14 days, and NR2a at 60 days, of withdrawal. HOMER1 addiction withdrawal 19306440 In contrast, extended access to cocaine resulted in distinct and long lasting alterations of protein expression within the mPFC that included: increased levels of Homer1b/c at 1 day, NR2b at 14 days, and NR2a at 60 days, of withdrawal. HOMER1 drug cocaine 19181855 Compared with WT mice, tPA / mice injected with cocaine displayed attenuated phosphorylation of ERK, cAMP response element binding protein (CREB), and dopamine and cAMP regulated phosphoprotein 32 kDa (DARPP 32) and blunted induction of immediate early genes (IEGs) c Fos, Egr 1, and Homer 1a in the amygdala and the nucleus accumbens (NAc).

HOMER1 drug cocaine 19118598 Neuroadaptations in the cellular and postsynaptic group 1 metabotropic glutamate receptor mGluR5 and Homer proteins following extinction of cocaine self administration. HOMER1 drug cocaine 19118598 This study examined the role of group1 metabotropic glutamate receptor mGluR5 and associated postsynaptic scaffolding protein Homer1b/c in behavioral plasticity after three withdrawal treatments from cocaine self administration. HOMER1 addiction withdrawal 19118598 This study examined the role of group1 metabotropic glutamate receptor mGluR5 and associated postsynaptic scaffolding protein Homer1b/c in behavioral plasticity after three withdrawal treatments from cocaine self administration. HOMER1 addiction withdrawal 19105975 At 21 days of withdrawal, there was a decrease in the expression of mGluR2/3 protein in core and shell, an increase in GluR1 and a decrease in Homer1b/c proteins in the nucleus accumbens core tissue. HOMER1 drug cocaine 18932227 Cocaine activates Homer1 immediate early gene transcription in the mesocorticolimbic circuit: differential regulation by dopamine and glutamate signaling. HOMER1 drug cocaine 18932227 Homer proteins have been implicated in synaptic and behavioral plasticity, including drug seeking behavior after cocaine treatment. HOMER1 addiction relapse 18932227 Homer proteins have been implicated in synaptic and behavioral plasticity, including drug seeking behavior after cocaine treatment. HOMER1 drug cocaine 18932227 In this study, using RT PCR, activation of Homer1a mRNA transcription in response to acute and repeated administration of cocaine was characterized in prefrontal cortex, nucleus accumbens, and ventral tegmental area, three mesocorticolimbic nuclei of the rat brain. HOMER1 drug cocaine 18932227 Moreover, the dopaminergic and glutamatergic regulation of Homer1 gene activation by cocaine was investigated. HOMER1 drug cocaine 18932227 Acute cocaine rapidly and transiently activated transcription of Homer1a mRNA in all three nuclei. HOMER1 drug cocaine 18932227 However, repeated administration of cocaine was not effective in inducing the Homer1a mRNA transcription after various withdrawal times ranging from 2 h to 3 weeks. HOMER1 addiction withdrawal 18932227 However, repeated administration of cocaine was not effective in inducing the Homer1a mRNA transcription after various withdrawal times ranging from 2 h to 3 weeks. HOMER1 drug cocaine 18932227 The acute cocaine mediated activation of Homer1 gene was regulated by D1 but not D2 dopamine receptors. HOMER1 drug cocaine 18932227 The blockade of AMPA or NMDA glutamate receptors did not prevent cocaine mediated activation of Homer1 gene in the three mesocorticolimbic nuclei. HOMER1 drug cocaine 18932227 These data indicate that acute administration of cocaine transiently activates Homer1 gene producing the immediate early gene Homer1a mRNA in the three mesocorticolimbic nuclei of the rat brain. HOMER1 drug cocaine 18932227 These data indicate that acute administration of cocaine transiently activates Homer1 gene producing the immediate early gene Homer1a mRNA in the three mesocorticolimbic nuclei of the rat brain. HOMER1 drug cocaine 18932227 Activation of Homer1 gene may contribute to the cocaine mediated synaptic and behavioral plasticity.

HOMER1 drug cocaine 17950706 The constitutively expressed (CC) Homer protein Homer2a/b actively regulates behavioral and neurochemical sensitivity to cocaine in both rats and mice. HOMER1 drug cocaine 17950706 The present study employed standard immunoblotting techniques to compare the effects of withdrawal from repeated cocaine (7 x 30 mg/kg) upon the protein expression of Homer2a/b with a related CC Homer protein Homer1b/c, as well as their associated glutamate receptors, within brain regions implicated in cocaine addiction.

HOMER1 drug cocaine 17950706 To determine whether or not the observed cocaine induced changes in Homer and glutamate receptor expression generalized across mammalian species, immunoblotting was conducted on tissue derived from both male Sprague Dawley rats and male C57BL/6J mice. HOMER1 drug cocaine 17950706 In both species, withdrawal from repeated cocaine administration down regulated Homer1b/c and Homer2a/b within the shell, but not the core, of the nucleus accumbens (NAC), and the reduced Homer levels were accompanied by decreases in mGluR1a, NR2a and NR2b. HOMER1 addiction withdrawal 17950706 In both species, withdrawal from repeated cocaine administration down regulated Homer1b/c and Homer2a/b within the shell, but not the core, of the nucleus accumbens (NAC), and the reduced Homer levels were accompanied by decreases in mGluR1a, NR2a and NR2b.

HOMER1 drug cocaine 17950706 In the PFC, repeated cocaine up regulated Homer2a/b, mGluR1 and NR2b expression, without affecting Homer1b/c levels. HOMER1 drug cocaine 17950706 Cocaine induced increases in Homer1b/c, Homer2a/b, mGluR1a and NR2a were observed in the hippocampus of both rats and mice, while in dorsal striatum, NR2a levels were elevated but Homer and Group1 mGluR levels were unchanged.

HOMER1 drug cocaine 17950706 Thus, withdrawal from repeated cocaine alters the expression of CC Homer isoforms and their associated glutamate receptors in a regionally distinct manner. HOMER1 addiction withdrawal 17950706 Thus, withdrawal from repeated cocaine alters the expression of CC Homer isoforms and their associated glutamate receptors in a regionally distinct manner. HOMER1 drug cocaine 17950706 As CC Homer proteins, Group1 mGluRs and NMDA receptors actively regulate cocaine induced neuroplasticity in vivo, these data support the hypothesis that cocaine induced changes in mGluR Homer NMDA signaling pathways may be important neuroadaptations mediating the enduring changes in behavior produced by repeated cocaine experience. HOMER1 drug alcohol 17568396 Homer proteins are integral components of the postsynaptic density that are necessary for alcohol induced neuroplasticity within the nucleus accumbens (NAC). HOMER1 drug alcohol 17568396 In this report, we describe the effects of chronic alcohol consumption upon NAC Homer expression and investigate the functional consequences of mimicking the alcohol induced changes in Homer expression vis à vis alcohol induced changes in NAC neurochemistry and behavior.

HOMER1 addiction dependence 16314758 Association of a polymorphism in the Homer1 gene with cocaine dependence in an African American population. HOMER1 drug cocaine 16314758 The purpose of this study is to determine whether single nucleotide polymorphisms in the Homer1 and Homer2 genes associate with the cocaine dependent phenotype in an African American population. HOMER1 drug cocaine 16314758 This study utilized a case control design in which the genotype and allele frequencies for four single nucleotide polymorphisms in the Homer1 gene and three single nucleotide polymorphisms in the Homer2 gene were compared between African American individuals with a diagnosis of cocaine dependence (n=170) and African American individuals with no history of substance abuse (n=90). HOMER1 addiction dependence 16314758 This study utilized a case control design in which the genotype and allele frequencies for four single nucleotide polymorphisms in the Homer1 gene and three single nucleotide polymorphisms in the Homer2 gene were compared between African American individuals with a diagnosis of cocaine dependence (n=170) and African American individuals with no history of substance abuse (n=90). HOMER1 drug cocaine 16314758 The data indicate that one single nucleotide polymorphism, rs6871510, located in intron 1 of the Homer1 gene significantly (P=0.029) associates with cocaine dependence at the genotype level, and trends toward a significant association at the allele frequency level (chi=2.62, df=1, P=0.106, OR=1.71). HOMER1 addiction dependence 16314758 The data indicate that one single nucleotide polymorphism, rs6871510, located in intron 1 of the Homer1 gene significantly (P=0.029) associates with cocaine dependence at the genotype level, and trends toward a significant association at the allele frequency level (chi=2.62, df=1, P=0.106, OR=1.71). HOMER1 drug cocaine 16314758 The results of this study suggest that a polymorphism in the Homer1 gene, rs6871510, is a potential risk factor for the development of cocaine dependence in an African American population, whereas polymorphisms in the Homer2 gene are not.

HOMER1 drug cocaine 16160706 Homer isoforms differentially regulate cocaine induced neuroplasticity. HOMER1 drug cocaine 16160706 Homer proteins modulate neuroplasticity in excitatory synapses and are dynamically regulated by cocaine. HOMER1 drug cocaine 16160706 Whereas acute cocaine elevates immediate early gene (short) isoforms of Homer1 in the nucleus accumbens, withdrawal from repeated cocaine administration downregulates the expression of constitutive Homer1 isoforms. HOMER1 addiction withdrawal 16160706 Whereas acute cocaine elevates immediate early gene (short) isoforms of Homer1 in the nucleus accumbens, withdrawal from repeated cocaine administration downregulates the expression of constitutive Homer1 isoforms. HOMER1 drug cocaine 16160706 The present study determined whether or not this downregulation in constitutive Homer expression in the accumbens is necessary for enduring alterations in cocaine induced changes in the brain and behavior. HOMER1 drug cocaine 16160706 The long vs short Homer isoforms were overexpressed in the rat nucleus accumbens during drug abstinence, and the adaptations elicited by repeated cocaine on glutamate transmission and motor behavior were measured. HOMER1 drug cocaine 16160706 It was found that both chronic and acute overexpression of constitutive, but not short, Homer isoforms abolished cocaine induced sensitization of locomotor hyperactivity and prevented the development of glutamate abnormalities in the accumbens, including the reduction in basal extracellular glutamate content and the sensitized glutamate response to a subsequent cocaine challenge injection.

HOMER1 drug cocaine 16160706 Together, these data indicate that the enduring reduction of long Homer isoforms in the nucleus accumbens of cocaine withdrawn rats is necessary for the expression of cocaine induced neuroplasticity. HOMER1 drug alcohol 16049182 Constitutive Homer2 gene deletion [knock out (KO)] and rescue with adeno associated viral (AAV) transfection of Homer2b was used to demonstrate the importance of Homer proteins in neuroplasticity produced by repeated ethanol (EtOH) administration. HOMER1 addiction addiction 16011574 Homer proteins are involved in the functional assembly of postsynaptic density proteins at glutamatergic synapses and are implicated in learning, memory and drug addiction. HOMER1 drug amphetamine 16011574 Relative to wild type mice, Homer1 KO mice exhibited deficits in radial arm maze performance, impaired prepulse inhibition, enhanced 'behavioral despair', increased anxiety in a novel objects test, enhanced reactivity to novel environments, decreased instrumental responding for sucrose and enhanced MK 801 and methamphetamine stimulated motor behavior. HOMER1 drug cocaine 16011574 Moreover, in Homer1 KO mice, cocaine did not stimulate a rise in frontal cortex extracellular glutamate levels, suggesting hypofrontality.

HOMER1 drug cocaine 15295029 We found that the cocaine induced blockade of retrograde signaling was correlated with enhanced expression levels of Homer scaffolding proteins containing the coiled coil domain and accompanied by a strong reduction of mGluR5 surface expression. HOMER1 drug cocaine 15294147 Homer proteins regulate sensitivity to cocaine. HOMER1 drug cocaine 15294147 Members of the Homer gene family are regulated by acute and chronic cocaine administration.

HOMER1 drug cocaine 14684444 (4) Homer1 protein is reduced in the nucleus accumbens, and Homer2 knockout mice show enhanced responsiveness to cocaine. HOMER1 drug cocaine 14511343 Homer1 proteins and AMPA receptors modulate cocaine induced behavioural plasticity. HOMER1 drug cocaine 14511343 Homer proteins form functional assemblies in the excitatory postsynaptic density, and withdrawal from repeated cocaine administration reduces the expression of Homer1b/c in the nucleus accumbens.

HOMER1 addiction sensitization 14511343 These data indicate that the expression of behavioural sensitization arises in part from a reduction in Homer1 gene products in the accumbens, while the development of sensitization requires stimulation of AMPA/kainate receptors. HOMER1 drug amphetamine 12774298 Differential regulation by stimulants of neocortical expression of mrt1, arc, and homer1a mRNA in the rats treated with repeated methamphetamine. HOMER1 drug cocaine 12774298 In contrast, the basal expression of other stimulant inducible and plasticity related genes arc and homer1a and the ability of MAP or cocaine challenge to augment the amounts of their transcripts were not affected by the repeated MAP regimen in the cortical area. HOMER1 addiction sensitization 12774298 These findings suggest the differential regulation by stimulant of neocortical mrt1, arc, and homer1a expression in the behaviorally sensitized animals and supports the view that stimulant induction of mrt1 may be involved in the early molecular signalings for stimulant sensitization. HOMER1 drug cocaine 12687634 Many genes upregulated in the CPu by cocaine were immediate early genes for transcription factors and for "effector" proteins (e.g., vesl/Homer1a, Arc, synaptotagmin IV).

CALCA drug opioid 29148033 Given that growing evidence indicates that calcitonin gene related peptide (CGRP) plays a key role in the development of peripheral sensitization and is associated with enhanced pain, we hypothesized that CGRP 4218T/C polymorphism is associated with the variability in fentanyl consumption for post cesarean analgesia. CALCA addiction sensitization 29148033 Given that growing evidence indicates that calcitonin gene related peptide (CGRP) plays a key role in the development of peripheral sensitization and is associated with enhanced pain, we hypothesized that CGRP 4218T/C polymorphism is associated with the variability in fentanyl consumption for post cesarean analgesia. CALCA drug opioid 29148033 We examined the association of CGRP 4218T/C polymorphism and post operative fentanyl consumption for analgesia as well as adverse reactions to fentanyl in those patients who received cesarean section surgeries. CALCA drug opioid 29148033 We found that the CGRP 4218T/C polymorphism has a significant effect on pain perception, analgesic requirement, and nausea and vomiting for the first 24 h after cesarean delivery in patients who received PCEA fentanyl. CALCA drug cannabinoid 28492437 Cannabinoid receptors were expressed not only in IB4 (isolectin B4) and CGRP (calcitonin gene related peptide) dorsal root ganglion neurons, their central terminals, and peripheral axons, but also in neurons, microglia, and astrocytes in spinal cord. CALCA drug opioid 28049076 Both the orbitofrontal cortex and amygdala are involved in the processing of olfactory information, and olfactory deficits may be also influenced by endogenous opioids and calcitonin gene related peptide (CGRP), which is probably involved in dopaminergic transmission. CALCA drug opioid 26748051 At doses providing equal or greater antinociception than morphine in the rat, the analogs showed reduced a) respiratory depression, b) impairment of motor coordination, c) tolerance and hyperalgesia, d) glial p38/CGRP/P2X7 receptor signaling, and e) reward/abuse potential in both conditioned place preference and self administration tests.

CALCA drug opioid 21571003 Sustained morphine treatment has been shown to produce paradoxical pain sensitization (opioid induced hyperalgesia) and also causes increase in spinal pain neurotransmitter, such as calcitonin gene related peptide (CGRP), concentration in experimental animals. CALCA addiction sensitization 21571003 Sustained morphine treatment has been shown to produce paradoxical pain sensitization (opioid induced hyperalgesia) and also causes increase in spinal pain neurotransmitter, such as calcitonin gene related peptide (CGRP), concentration in experimental animals. CALCA drug opioid 21571003 We have previously shown that in cultured primary sensory dorsal root ganglion (DRG) neurons sustained in vitro opioid agonist treatment upregulates cAMP levels (adenylyl cyclase (AC) superactivation) and augments basal and capsaicin evoked CGRP release in a PKA dependent manner. CALCA drug opioid 21571003 pretreatment of rats with a PKA selective small interference RNA (siRNA) mixture significantly attenuates sustained morphine mediated augmentation of spinal CGRP immunoreactivity, thermal hyperalgesia, mechanical allodynia and antinociceptive tolerance. CALCA drug opioid 20970925 The present study examines the effects of intraplantar injection of the μ and δ opioid receptor agonists, morphine and deltorphin, alone and in combination on behavioral tests of nociception in naïve rats and on potassium evoked release of CGRP from sciatic nerves of naïve rats. CALCA drug opioid 20970925 Similarly, concentration dependent inhibition of CGRP release was observed when deltorphin and morphine were administered in sequence prior to potassium stimulation. CALCA drug opioid 20826131 In the present work we investigated the hypothesis that morphine pretreatment also sensitizes ACs toward Gs protein coupled excitatory modulators (such as PGE₂), leading to augmented PKA dependent CGRP release from PGE₂ stimulated primary sensory dorsal root ganglion (DRG) neurons. CALCA drug opioid 20826131 Our results show that sustained morphine treatment potentiated PGE₂ mediated cAMP formation and augmented PGE₂ evoked CGRP release from cultured primary sensory neurons in a PKA dependent manner. CALCA drug opioid 20727859 Induction of viscerosomatic hypersensitivity resulted in an increased labeling of CGRP , but not substance P positive cells in the lumbar dorsal root ganglia; increased labeling was not affected by prior exposure to morphine. CALCA drug opioid 20718739 Long term morphine treatment enhances pain neurotransmitter [such as calcitonin gene related peptide (CGRP)] levels in the spinal cord. CALCA drug opioid 20718739 It has been suggested previously that increased spinal CGRP may contribute to sustained morphine mediated paradoxical pain sensitization and antinociceptive tolerance. CALCA addiction sensitization 20718739 It has been suggested previously that increased spinal CGRP may contribute to sustained morphine mediated paradoxical pain sensitization and antinociceptive tolerance. CALCA drug opioid 20718739 Previous in vitro studies from our group indicated that Raf 1 kinase mediated adenylyl cyclase superactivation played a crucial role in sustained morphine mediated augmentation of basal and evoked CGRP release from cultured primary sensory neurons. CALCA drug opioid 20718739 Selective knockdown of spinal Raf 1 protein levels by i.th Raf 1 selective siRNA pretreatment significantly attenuated sustained morphine mediated up regulation of CGRP immunoreactivity in the spinal cord of rats and prevented the development of thermal hyperalgesia, mechanical allodynia and antinociceptive tolerance. CALCA drug opioid 20659434 Involvement of opioid receptors in the CGRP induced antinociception in the nucleus accumbens of rats. CALCA drug opioid 20659434 The present study is performed to explore the possible involvement of opioid receptors in the CGRP induced antinociception in the NAc of rats. CALCA addiction withdrawal 20659434 Intra NAc administration of CGRP induces significant increases in the hindpaw withdrawal latency (HWL) to noxious thermal and mechanical stimulation in rats. CALCA drug opioid 20659434 Interestingly, the CGRP induced antinociceptive effects are inhibited by following intra NAc injection of the opioid receptor antagonist naloxone, suggesting that the opioid receptors are involved in the CGRP induced antinociception in the NAc of rats. CALCA drug opioid 20659434 Furthermore, the CGRP induced antinociception is attenuated by intra NAc injection of mu opioid receptor (MOR) antagonist beta funaltrexamine (beta FNA) and kappa opioid receptor (KOR) antagonist nor binaltorphimine (nor BNI), but not by delta receptor (DOR) antagonist naltrindole. CALCA drug opioid 20659434 In the present study, we also demonstrated that there was no significant difference between the CGRP induced antinociception and the morphine induced antinociception in the NAc in rats. CALCA drug opioid 20659434 The results of the present study demonstrate that both mu and kappa opioid receptors are involved in the CGRP induced antinociception in the NAc of rats. CALCA drug opioid 20359526 Several groups maintain that morphine tolerance and dependence correlate with increased activity of protein kinases ERK1/2 and P38 MAPK and PKC as well as elevated levels of the neuropeptides dynorphin (DYN), substance P (sP), and calcitonin gene related peptide (CGRP) in spinal cord dorsal horn (SCDH). CALCA addiction dependence 20359526 Several groups maintain that morphine tolerance and dependence correlate with increased activity of protein kinases ERK1/2 and P38 MAPK and PKC as well as elevated levels of the neuropeptides dynorphin (DYN), substance P (sP), and calcitonin gene related peptide (CGRP) in spinal cord dorsal horn (SCDH). CALCA drug opioid 20359526 In contrast, while morphine increased spinal DYN and CGRP in WT mice, DYN remained unchanged and CGRP was reduced in GluR5 KO mice. CALCA drug opioid 20359526 These observations suggest that spinal ERK2, P38 and PKCgamma are likely involved in multiple adaptive responses following systemic morphine administration, whereas DYN and CGRP may contribute selectively to the development of antinociceptive tolerance. CALCA drug opioid 19491327 It was shown previously (J Neurosci 22:6747 6755, 2002) that sustained morphine exposure augments pain neurotransmitter [such as calcitonin gene related peptide (CGRP)] release in the dorsal horn of the spinal cord in response to the heat sensing transient receptor potential vanilloid 1 receptor agonist 8 methyl N vanillyl 6 nonenamide (capsaicin). CALCA drug opioid 19491327 In the present study, we demonstrate that sustained morphine mediated augmentation of CGRP release from isolated primary sensory dorsal root ganglion neurons is dependent on protein kinase A and Raf 1 kinase. CALCA drug cannabinoid 19387418 Sustained cannabinoid agonist treatment augments CGRP release in a PKA dependent manner. CALCA addiction sensitization 19387418 It has been suggested that augmented release of pain neurotransmitters (such as calcitonin gene related peptide, CGRP) might be responsible for this abnormal pain sensitization. CALCA drug cannabinoid 19387418 We hypothesize that intracellular adaptations upon sustained cannabinoid treatment causes augmented release of CGRP from primary nociceptors leading to increased pain sensitivity. CALCA drug cannabinoid 19387418 We show that sustained (24 h) cannabinoid agonist [(+)WIN 55,212 2] treatment of 7 day old neonatal rat dorsal root ganglion neurons significantly augments basal CGRP release from these cells in a protein kinase A dependent manner. CALCA drug opioid 18976650 Enhanced excitatory pain neurotransmitter (such as calcitonin gene related peptide (CGRP)) release in the dorsal horn of the spinal cord may play a role in sustained morphine mediated paradoxical pain. CALCA drug opioid 18976650 Recently we have demonstrated that inhibition of Raf 1 attenuates sustained morphine treatment mediated augmentation of CGRP release in vitro, in cultured primary sensory neurons.

CALCA drug opioid 18328477 The intracellular signal transduction pathways involved in sustained opioid mediated augmentation of spinal pain neurotransmitter (such as calcitonin gene related peptide (CGRP)) release are not fully clarified. CALCA drug opioid 18328477 Therefore, in the present study we examined the role of Raf 1 in sustained morphine mediated regulation of cAMP formation and basal CGRP release in vitro, in cultured neonatal rat dorsal root ganglion (DRG) neurons. CALCA drug opioid 18328477 We found that sustained morphine treatment significantly augments intracellular cAMP production as well as basal CGRP release from cultured neonatal rat DRG neurons. CALCA drug opioid 18328477 The selective PKA inhibitor, H 89, attenuates the sustained morphine mediated augmentation of basal CGRP release, indicating that the cAMP/PKA pathway plays an important role in regulation of CGRP release from sensory neurons. CALCA drug opioid 18328477 Since our present data also demonstrated that selective Raf 1 inhibitor, GW 5074, attenuated both the cAMP overshoot and the augmentation of CGRP release mediated by sustained morphine in neonatal rat DRG neurons, we suggest that Raf 1 mediated sensitization of the intracellular cAMP formation may play an important role in sustained morphine mediated augmentation of spinal pain neurotransmitter release. CALCA addiction sensitization 18328477 Since our present data also demonstrated that selective Raf 1 inhibitor, GW 5074, attenuated both the cAMP overshoot and the augmentation of CGRP release mediated by sustained morphine in neonatal rat DRG neurons, we suggest that Raf 1 mediated sensitization of the intracellular cAMP formation may play an important role in sustained morphine mediated augmentation of spinal pain neurotransmitter release. CALCA addiction sensitization 17693023 As the anti NGF antibody does not appreciably cross the blood brain barrier, the present data suggest that the anti hyperalgesic action of anti NGF therapy results from blockade of activation and/or sensitization of the CGRP/trkA positive fibers that normally constitute the majority of sensory fibers that innervate the bone.

ADH4 addiction dependence 11545539 In Asians, variation in the alcohol dehydrogenase (ADH2) gene relates to alcohol dependence, alcohol consumption, and reported alcohol related symptoms, even after controlling for variation in the aldehyde dehydrogenase (ALDH2) gene. ADH4 drug alcohol 11545539 The association of ADH2 polymorphisms with alcohol related behavior, however, has not been well characterized in non Asians. ADH4 drug alcohol 11545539 ADH2*2, however, was not related to alcohol use disorders, alcohol induced flushing and associated symptoms, number of binge drinking episodes in the past 90 days, maximum number of drinks ever consumed, or self reported levels of response to alcohol. ADH4 addiction intoxication 11545539 ADH2*2, however, was not related to alcohol use disorders, alcohol induced flushing and associated symptoms, number of binge drinking episodes in the past 90 days, maximum number of drinks ever consumed, or self reported levels of response to alcohol. ADH4 drug alcohol 11545539 Results suggest that Ashkenazic Jewish Americans with ADH2*2 alleles drink less frequently, which might contribute, in part, to the overall lower rates of alcoholism in this population. ADH4 drug alcohol 11315223 In men, effects of alcohol dehydrogenase ADH2*1/*2 genotype or high alcohol sensitivity (risk decreasing), and of history of childhood conduct disorder, or having monozygotic co twin or twin sister with AlcD (risk increasing) were significant and comparable in magnitude. ADH4 drug alcohol 10630602 An alcohol dependent patient was identified to be ALDH2*2/*2, ADH2*2/*2, and ADH3*1/*2. ADH4 drug alcohol 10630602 Logistic regression analysis of the combinatorial genotypes of ADH2 and ALDH2 in 420 alcohol dependent and 689 nonalcohol dependent subjects indicated that risk for alcoholism was 100 fold lower for the ADH2*2/*2 ALDH2*2/*2 individuals than the ADH2*1/*1 ALDH2*1/*1 individuals. ADH4 drug alcohol 10235293 The different genotypes at the genes encoding the enzymes involved in alcohol metabolism, class one alcohol dehydrogenase (ADH2 and ADH3) and mitochondrial aldehyde dehydrogenase (ALDH2), have previously been shown to confer different predispositions to the development of alcoholism in Chinese Han males (Thomasson et al., 1991; Chen WJ et al., 1996; Chen CC et al., unpublished data). ADH4 drug alcohol 10235293 Therefore, association studies of alcoholism in Chinese Han might be more sensitive if controlled for the genotypes of ADH2,ADH3, and ALDH2, when other loci, such as DRD2, are examined. ADH4 drug alcohol 10235293 These tests included considering the high risk (ADH2*1/*1; *1/*2; ADH3*1/*2; *2/*2; and ALDH2*1/*1) and the low risk (ADH2*2/*2; ADH3*1/*1; and ALDH2*1/*2; *2/*2) groups of alcoholics, as well as nonalcoholic controls. ADH4 drug alcohol 10235293 After stratification by the relevant genotypes of ADH2, ADH3, and ALDH2 no significant association exists between the genetic variants at the DRD2 locus and alcoholism in the Chinese Han population. ADH4 addiction dependence 9802529 ADH2 genotype had significant effects on both consumption and dependence in the men, but not in the women. ADH4 drug alcohol 9509496 Men with an ADH2 x 3 allele had significantly higher amplitude P3 components at placebo and also demonstrated more alcohol induced reductions in P3 amplitude than men with ADH2 x 1 alleles only. ADH4 drug alcohol 9373704 The purpose of this paper is to assemble and evaluate existing data on the effect of genetic variation in ADH2 and ADH3 on the risk of alcohol dependence, and on the risk of alcoholic liver disease. ADH4 addiction dependence 9373704 The purpose of this paper is to assemble and evaluate existing data on the effect of genetic variation in ADH2 and ADH3 on the risk of alcohol dependence, and on the risk of alcoholic liver disease. ADH4 drug alcohol 9373704 It is clear that possession of the ADH2 2 allele decreases the risk of alcohol dependence, but it increases the risk of alcoholic liver disease among alcoholics. ADH4 addiction dependence 9373704 It is clear that possession of the ADH2 2 allele decreases the risk of alcohol dependence, but it increases the risk of alcoholic liver disease among alcoholics. ADH4 drug alcohol 9373704 ADH3 variation also has significant effects on alcohol dependence, which may be due to linkage to ADH2; the ADH3 effect differs significantly between Asian and European subjects. ADH4 addiction dependence 9373704 ADH3 variation also has significant effects on alcohol dependence, which may be due to linkage to ADH2; the ADH3 effect differs significantly between Asian and European subjects. ADH4 drug alcohol 9066994 In this report we determined the genotypes for three genes, ADH2, ADH3, and ALDH2 among subjects with alcohol dependence (n = 159) and ethnically matched normal controls (n = 149) for the four largest aboriginal groups (Atayal, Ami, Bunun, and Paiwan) in Taiwan. ADH4 addiction dependence 9066994 In this report we determined the genotypes for three genes, ADH2, ADH3, and ALDH2 among subjects with alcohol dependence (n = 159) and ethnically matched normal controls (n = 149) for the four largest aboriginal groups (Atayal, Ami, Bunun, and Paiwan) in Taiwan. ADH4 drug alcohol 9066994 On an individual level, however, the genotypes controlling alcohol metabolism did not account for intragroup differences in vulnerability to alcoholism except in the case of ADH2 for the Ami ethnic group. ADH4 drug alcohol 8904964 The influences of estimated body water, recent drinking history, recent smoking history, polymorphism at the ADH2 and ADH3 loci, family history of alcoholism, and percentage Native American heritage on alcohol elimination rate were determined using multiple regression analyses. ADH4 drug nicotine 8904964 The influences of estimated body water, recent drinking history, recent smoking history, polymorphism at the ADH2 and ADH3 loci, family history of alcoholism, and percentage Native American heritage on alcohol elimination rate were determined using multiple regression analyses. ADH4 drug alcohol 8904964 There was also a nonsignificant trend for subjects with an ADH2*3 allele (n = 6) to have faster rates of alcohol elimination than those with ADH2*1 alleles only (n = 33). ADH4 drug alcohol 8773821 Alcohol metabolising genes and alcoholism among Taiwanese Han men: independent effect of ADH2, ADH3 and ALDH2. ADH4 drug alcohol 8773821 The association of ALDH2 and ADH2 with the development of alcoholism was found to be independent of each other and has been replicated in different Asian populations, while the effect of ADH3 is less studied. ADH4 drug alcohol 8773821 Multiple logistic regression was then applied to assess the contribution of ADH3 to alcoholism by controlling the effect of ALDH2 and ADH2. ADH4 drug alcohol 8773821 The results of multivariate analyses demonstrated that the odds ratios for an increment of one allele of ADH2*1, ADH3*2 and ALDH2*1 in the development of alcoholism were 4.18, 3.82, and 6.89, respectively. ADH4 drug alcohol 8651462 A comparison of the genotypes of ALDH2, ADH2, ADH3, and cytochrome P 4502E1 between alcoholics and nonalcoholics. ADH4 drug alcohol 8651462 Our study revealed differences in the allelic frequencies of the ALDH2, ADH2, and ADH3 loci between alcoholics and nonalcoholics. ADH4 drug alcohol 8651462 For alcoholics with both homozygous ALDH2*1/1 and heterozygous ALDH2*1/2 genotypes, it was found that ADH2 and ADH3 played important rates. ADH4 drug alcohol 8651462 Alcoholics with the heterozygous ALDH2*1/2 genotype showed a significantly higher frequency of ADH2*1/1 than ones with the homozygous ALDH2*1/1 genotype. ADH4 drug alcohol 8651462 We assume ADH2*1 plays an important role in the development of alcoholism in alcoholics with the heterozygous ALDH2*1/2 genotype. ADH4 drug alcohol 8591846 High incidence of ADH2*1/ALDH2*1 genes among Japanese alcohol dependents and patients with alcoholic liver disease. ADH4 drug alcohol 8591846 Genetic polymorphism of ADH2/ALDH2 in 66 cases of normal subjects, 90 cases of alcohol dependent, and 31 patients with alcoholic liver disease among Japanese has been analyzed using a polymerase chain reaction assay followed by a direct sequencing method, because ethanol is mainly catabolized by ADH and ALDH and less by cytochrome P450IIE1 and catalase. ADH4 drug alcohol 8591846 The incidence of both ADH2*1/*1 and ALDH2*1/*1 was significantly higher in patients with alcohol dependence and in patients with alcoholic liver disease when compared with that in control subjects. ADH4 addiction dependence 8591846 The incidence of both ADH2*1/*1 and ALDH2*1/*1 was significantly higher in patients with alcohol dependence and in patients with alcoholic liver disease when compared with that in control subjects. ADH4 drug alcohol 8591846 Genetic polymorphism of ADH2/ALDH2 in patients with alcoholic liver disease was not different from that of alcohol dependents. ADH4 drug alcohol 8591846 According to these results, not only ALDH2 gene, often claimed to be responsible for alcohol dependence among Japanese, but also ADH2 gene polymorphism, which modulates the metabolism of ethanol, play important roles in habitual alcohol intake behavior in Japanese patients and in some patients leads to alcoholic liver diseases. ADH4 addiction dependence 8591846 According to these results, not only ALDH2 gene, often claimed to be responsible for alcohol dependence among Japanese, but also ADH2 gene polymorphism, which modulates the metabolism of ethanol, play important roles in habitual alcohol intake behavior in Japanese patients and in some patients leads to alcoholic liver diseases. ADH4 drug alcohol 7943668 Low frequency of the ADH2*2 allele among Atayal natives of Taiwan with alcohol use disorders. ADH4 drug alcohol 7943668 Genetic variation at two polymorphic alcohol dehydrogenase loci, ADH2 and ADH3, and at the polymorphic mitochondrial aldehyde dehydrogenase locus, ALDH2, may influence the risk of developing alcoholism by modulating the rate of elimination of ethanol and the rate of formation and elimination of acetaldehyde. ADH4 drug alcohol 7943668 Among the Atayal, the group with alcohol use disorders (alcohol dependence and alcohol abuse) had a significantly lower frequency of the ADH2*2 allele (0.82) than those without alcohol use disorders (0.91). ADH4 addiction dependence 7943668 Among the Atayal, the group with alcohol use disorders (alcohol dependence and alcohol abuse) had a significantly lower frequency of the ADH2*2 allele (0.82) than those without alcohol use disorders (0.91). ADH4 drug alcohol 7943668 The ADH2*2 allele encodes the beta 2 subunit; isozymes containing beta 2 subunits oxidize alcohol faster in vitro than the beta 1 beta 1 isozyme encoded by ADH2*1. ADH4 drug alcohol 3189338 Genetic polymorphisms of two major alcohol metabolizing enzymes i.e., one of the class I alcohol dehydrogenase isozymes (ADH2) and the mitochondrial aldehyde dehydrogenase (ALDH2) exist in Japanese and other Orientals but not in Caucasians. ADH4 drug alcohol 3189338 We determined, by means of hybridization of genomic DNA samples with allele specific synthetic oligonucleotide probes, genotypes of the ADH2 and the ALDH2 loci of Japanese with alcoholic liver diseases and of control subjects. ADH4 drug alcohol 2940107 Starch gel electrophoresis of rat ocular tissues shows two anodic isoenzymes of alcohol dehydrogenase (ADH), designated as ADH 1 and ADH 2, ADH 1 is characteristic of the ocular tissues, and corresponds to more than 95% of all ADH activity in the eye. ADH4 drug alcohol 6321953 Seven cis dominant mutations leading to the overproduction of the glucose repressible alcohol dehydrogenase isozyme ADHII (structural gene, ADH2) in Saccharomyces cerevisiae have previously been shown to be due to insertion of a transposable element, Ty, in the 5' regulatory region of the ADH2 gene. S100A12 drug opioid 31794788 The rest of the 5 brainstem tissues were then used to measure CCK, CGRP, and opioid peptide receptor (DORR) levels by western blotting(WB). S100A12 addiction sensitization 31551772 TRPV1 contributes to peripheral sensitization and hyperalgesia, in part, via triggering the release of proinflammatory peptides, such as calcitonin gene related peptide (CGRP), both locally and at the dorsal horn of the spinal cord. S100A12 drug opioid 31551772 Blocking TRPV1, but not opioid receptors, attenuated the onset of analgesia and capsaicin induced CGRP release. S100A12 drug opioid 31010055 We evaluated the mechanical paw withdrawal threshold (MWT) and expression of melatonin receptor 1 (MT1), melatonin receptor 2 (MT2), μ (MOR) and κ (KOR) opioid receptor, brain derived neurotrophic factor (BDNF), Substance P, and calcitonin gene related peptide (CGRP) in cuneate nucleus, dorsal horn, and hind paw skin by immunohistochemical, immunofluorescence assays and real time quantitative polymerase chain reaction (RT PCR).

S100A12 addiction sensitization 30706780 On the basis of their anatomic location, transient receptor potential ion channels (TRPV1, TRPV2 and TRPM8), Piezo 2, acid sensing ion channels (ASICs), purinergic (P2X and P2Y), bradykinin (B1 and B2), α amino 3 hydroxy 5 methylisoxazole 4 propionate (AMPA), N methyl D aspartate (NMDA), metabotropic glutamate (mGlu), neurokinin 1 (NK1) and calcitonin gene related peptide (CGRP) receptors are activated during pain sensitization. S100A12 drug cannabinoid 30342013 They include peptides targeting Ca2+, Na+ and K+ voltage gated ion channels, the neuronal nicotinic receptors (nAChR), transient receptor potential channels (TRP), and different non opioid G protein coupled receptors (GPCRs), like the calcitonin gen related peptide (CGRP), cannabinoid, bradykinin and neurotensin receptors, among others.

S100A12 drug opioid 29148033 Given that growing evidence indicates that calcitonin gene related peptide (CGRP) plays a key role in the development of peripheral sensitization and is associated with enhanced pain, we hypothesized that CGRP 4218T/C polymorphism is associated with the variability in fentanyl consumption for post cesarean analgesia. S100A12 addiction sensitization 29148033 Given that growing evidence indicates that calcitonin gene related peptide (CGRP) plays a key role in the development of peripheral sensitization and is associated with enhanced pain, we hypothesized that CGRP 4218T/C polymorphism is associated with the variability in fentanyl consumption for post cesarean analgesia. S100A12 drug opioid 29148033 We examined the association of CGRP 4218T/C polymorphism and post operative fentanyl consumption for analgesia as well as adverse reactions to fentanyl in those patients who received cesarean section surgeries. S100A12 drug opioid 29148033 We found that the CGRP 4218T/C polymorphism has a significant effect on pain perception, analgesic requirement, and nausea and vomiting for the first 24 h after cesarean delivery in patients who received PCEA fentanyl. S100A12 drug cannabinoid 28492437 Cannabinoid receptors were expressed not only in IB4 (isolectin B4) and CGRP (calcitonin gene related peptide) dorsal root ganglion neurons, their central terminals, and peripheral axons, but also in neurons, microglia, and astrocytes in spinal cord. S100A12 drug opioid 28049076 Both the orbitofrontal cortex and amygdala are involved in the processing of olfactory information, and olfactory deficits may be also influenced by endogenous opioids and calcitonin gene related peptide (CGRP), which is probably involved in dopaminergic transmission. S100A12 drug opioid 26748051 At doses providing equal or greater antinociception than morphine in the rat, the analogs showed reduced a) respiratory depression, b) impairment of motor coordination, c) tolerance and hyperalgesia, d) glial p38/CGRP/P2X7 receptor signaling, and e) reward/abuse potential in both conditioned place preference and self administration tests.

S100A12 drug opioid 24824948 RT PCR and Western blot analysis showed that NaHS significantly reversed the gene and protein expression of up regulated spinal calcitonin gene related peptide (CGRP) in naloxone treated animals. S100A12 drug opioid 24824948 Our data suggest that H2S prevents the development of opioid withdrawal induced hyperalgesia via suppression of synthesis of CGRP in spine through inhibition of AC/cAMP and PKC/Raf 1/ERK pathways. S100A12 addiction withdrawal 24824948 Our data suggest that H2S prevents the development of opioid withdrawal induced hyperalgesia via suppression of synthesis of CGRP in spine through inhibition of AC/cAMP and PKC/Raf 1/ERK pathways. S100A12 drug opioid 23244430 The present review discusses the neurobiology of opioid withdrawal syndrome and its therapeutic target recptors like calcitonin gene related peptide receptors (CGRP), N methyl D aspartate (NMDA) receptors, gamma aminobutyric acid receptors (GABA), G proteingated inwardly rectifying potassium (GIRK) channels and calcium channels.

S100A12 drug cannabinoid 21631400 The present review discusses these therapeutic targets including noradrenaline and 5 HT reuptake inhibitors; sodium, calcium and potassium channels; inhibitory and excitatory neurotransmitters; neuropeptides including bradykinin, tachykinin, cholecystokinin, neuropeptide Y, vasoactive intestinal peptide, and CGRP; pro inflammatory cytokines; MAP kinases; PPAR γ; Na(+)/Ca(2+) exchanger; nitric oxide; purinergic receptors; neuronal nicotinic receptors; cation dependent chloride transporters; oxidative stress; matrix metalloproteinase and plasminogen activators; growth factors; transient receptor potential (TRP) channels; endocannabinoids; histamine receptors; dopamine; sigma receptors, beta adrenergic receptors, endothelins, and D amino acid oxidase. S100A12 drug opioid 21571003 Sustained morphine treatment has been shown to produce paradoxical pain sensitization (opioid induced hyperalgesia) and also causes increase in spinal pain neurotransmitter, such as calcitonin gene related peptide (CGRP), concentration in experimental animals. S100A12 addiction sensitization 21571003 Sustained morphine treatment has been shown to produce paradoxical pain sensitization (opioid induced hyperalgesia) and also causes increase in spinal pain neurotransmitter, such as calcitonin gene related peptide (CGRP), concentration in experimental animals. S100A12 drug opioid 21571003 We have previously shown that in cultured primary sensory dorsal root ganglion (DRG) neurons sustained in vitro opioid agonist treatment upregulates cAMP levels (adenylyl cyclase (AC) superactivation) and augments basal and capsaicin evoked CGRP release in a PKA dependent manner. S100A12 drug opioid 21571003 pretreatment of rats with a PKA selective small interference RNA (siRNA) mixture significantly attenuates sustained morphine mediated augmentation of spinal CGRP immunoreactivity, thermal hyperalgesia, mechanical allodynia and antinociceptive tolerance. S100A12 drug opioid 20970925 The present study examines the effects of intraplantar injection of the μ and δ opioid receptor agonists, morphine and deltorphin, alone and in combination on behavioral tests of nociception in naïve rats and on potassium evoked release of CGRP from sciatic nerves of naïve rats. S100A12 drug opioid 20970925 Similarly, concentration dependent inhibition of CGRP release was observed when deltorphin and morphine were administered in sequence prior to potassium stimulation. S100A12 drug opioid 20826131 In the present work we investigated the hypothesis that morphine pretreatment also sensitizes ACs toward Gs protein coupled excitatory modulators (such as PGE₂), leading to augmented PKA dependent CGRP release from PGE₂ stimulated primary sensory dorsal root ganglion (DRG) neurons. S100A12 drug opioid 20826131 Our results show that sustained morphine treatment potentiated PGE₂ mediated cAMP formation and augmented PGE₂ evoked CGRP release from cultured primary sensory neurons in a PKA dependent manner. S100A12 drug opioid 20727859 Induction of viscerosomatic hypersensitivity resulted in an increased labeling of CGRP , but not substance P positive cells in the lumbar dorsal root ganglia; increased labeling was not affected by prior exposure to morphine. S100A12 drug opioid 20718739 Long term morphine treatment enhances pain neurotransmitter [such as calcitonin gene related peptide (CGRP)] levels in the spinal cord. S100A12 drug opioid 20718739 It has been suggested previously that increased spinal CGRP may contribute to sustained morphine mediated paradoxical pain sensitization and antinociceptive tolerance. S100A12 addiction sensitization 20718739 It has been suggested previously that increased spinal CGRP may contribute to sustained morphine mediated paradoxical pain sensitization and antinociceptive tolerance. S100A12 drug opioid 20718739 Previous in vitro studies from our group indicated that Raf 1 kinase mediated adenylyl cyclase superactivation played a crucial role in sustained morphine mediated augmentation of basal and evoked CGRP release from cultured primary sensory neurons. S100A12 drug opioid 20718739 Selective knockdown of spinal Raf 1 protein levels by i.th Raf 1 selective siRNA pretreatment significantly attenuated sustained morphine mediated up regulation of CGRP immunoreactivity in the spinal cord of rats and prevented the development of thermal hyperalgesia, mechanical allodynia and antinociceptive tolerance. S100A12 drug opioid 20659434 Involvement of opioid receptors in the CGRP induced antinociception in the nucleus accumbens of rats. S100A12 drug opioid 20659434 The present study is performed to explore the possible involvement of opioid receptors in the CGRP induced antinociception in the NAc of rats. S100A12 addiction withdrawal 20659434 Intra NAc administration of CGRP induces significant increases in the hindpaw withdrawal latency (HWL) to noxious thermal and mechanical stimulation in rats. S100A12 drug opioid 20659434 Interestingly, the CGRP induced antinociceptive effects are inhibited by following intra NAc injection of the opioid receptor antagonist naloxone, suggesting that the opioid receptors are involved in the CGRP induced antinociception in the NAc of rats. S100A12 drug opioid 20659434 Furthermore, the CGRP induced antinociception is attenuated by intra NAc injection of mu opioid receptor (MOR) antagonist beta funaltrexamine (beta FNA) and kappa opioid receptor (KOR) antagonist nor binaltorphimine (nor BNI), but not by delta receptor (DOR) antagonist naltrindole. S100A12 drug opioid 20659434 In the present study, we also demonstrated that there was no significant difference between the CGRP induced antinociception and the morphine induced antinociception in the NAc in rats. S100A12 drug opioid 20659434 The results of the present study demonstrate that both mu and kappa opioid receptors are involved in the CGRP induced antinociception in the NAc of rats. S100A12 drug opioid 20359526 Several groups maintain that morphine tolerance and dependence correlate with increased activity of protein kinases ERK1/2 and P38 MAPK and PKC as well as elevated levels of the neuropeptides dynorphin (DYN), substance P (sP), and calcitonin gene related peptide (CGRP) in spinal cord dorsal horn (SCDH). S100A12 addiction dependence 20359526 Several groups maintain that morphine tolerance and dependence correlate with increased activity of protein kinases ERK1/2 and P38 MAPK and PKC as well as elevated levels of the neuropeptides dynorphin (DYN), substance P (sP), and calcitonin gene related peptide (CGRP) in spinal cord dorsal horn (SCDH). S100A12 drug opioid 20359526 In contrast, while morphine increased spinal DYN and CGRP in WT mice, DYN remained unchanged and CGRP was reduced in GluR5 KO mice. S100A12 drug opioid 20359526 These observations suggest that spinal ERK2, P38 and PKCgamma are likely involved in multiple adaptive responses following systemic morphine administration, whereas DYN and CGRP may contribute selectively to the development of antinociceptive tolerance. S100A12 drug opioid 19491327 It was shown previously (J Neurosci 22:6747 6755, 2002) that sustained morphine exposure augments pain neurotransmitter [such as calcitonin gene related peptide (CGRP)] release in the dorsal horn of the spinal cord in response to the heat sensing transient receptor potential vanilloid 1 receptor agonist 8 methyl N vanillyl 6 nonenamide (capsaicin). S100A12 drug opioid 19491327 In the present study, we demonstrate that sustained morphine mediated augmentation of CGRP release from isolated primary sensory dorsal root ganglion neurons is dependent on protein kinase A and Raf 1 kinase. S100A12 drug cannabinoid 19387418 Sustained cannabinoid agonist treatment augments CGRP release in a PKA dependent manner. S100A12 addiction sensitization 19387418 It has been suggested that augmented release of pain neurotransmitters (such as calcitonin gene related peptide, CGRP) might be responsible for this abnormal pain sensitization. S100A12 drug cannabinoid 19387418 We hypothesize that intracellular adaptations upon sustained cannabinoid treatment causes augmented release of CGRP from primary nociceptors leading to increased pain sensitivity. S100A12 drug cannabinoid 19387418 We show that sustained (24 h) cannabinoid agonist [(+)WIN 55,212 2] treatment of 7 day old neonatal rat dorsal root ganglion neurons significantly augments basal CGRP release from these cells in a protein kinase A dependent manner. S100A12 drug opioid 18976650 Enhanced excitatory pain neurotransmitter (such as calcitonin gene related peptide (CGRP)) release in the dorsal horn of the spinal cord may play a role in sustained morphine mediated paradoxical pain. S100A12 drug opioid 18976650 Recently we have demonstrated that inhibition of Raf 1 attenuates sustained morphine treatment mediated augmentation of CGRP release in vitro, in cultured primary sensory neurons. S100A12 drug opioid 18328477 Sustained morphine treatment augments basal CGRP release from cultured primary sensory neurons in a Raf 1 dependent manner. S100A12 drug opioid 18328477 The intracellular signal transduction pathways involved in sustained opioid mediated augmentation of spinal pain neurotransmitter (such as calcitonin gene related peptide (CGRP)) release are not fully clarified. S100A12 drug opioid 18328477 Therefore, in the present study we examined the role of Raf 1 in sustained morphine mediated regulation of cAMP formation and basal CGRP release in vitro, in cultured neonatal rat dorsal root ganglion (DRG) neurons. S100A12 drug opioid 18328477 We found that sustained morphine treatment significantly augments intracellular cAMP production as well as basal CGRP release from cultured neonatal rat DRG neurons. S100A12 drug opioid 18328477 The selective PKA inhibitor, H 89, attenuates the sustained morphine mediated augmentation of basal CGRP release, indicating that the cAMP/PKA pathway plays an important role in regulation of CGRP release from sensory neurons. S100A12 drug opioid 18328477 Since our present data also demonstrated that selective Raf 1 inhibitor, GW 5074, attenuated both the cAMP overshoot and the augmentation of CGRP release mediated by sustained morphine in neonatal rat DRG neurons, we suggest that Raf 1 mediated sensitization of the intracellular cAMP formation may play an important role in sustained morphine mediated augmentation of spinal pain neurotransmitter release. S100A12 addiction sensitization 18328477 Since our present data also demonstrated that selective Raf 1 inhibitor, GW 5074, attenuated both the cAMP overshoot and the augmentation of CGRP release mediated by sustained morphine in neonatal rat DRG neurons, we suggest that Raf 1 mediated sensitization of the intracellular cAMP formation may play an important role in sustained morphine mediated augmentation of spinal pain neurotransmitter release. S100A12 addiction sensitization 17693023 As the anti NGF antibody does not appreciably cross the blood brain barrier, the present data suggest that the anti hyperalgesic action of anti NGF therapy results from blockade of activation and/or sensitization of the CGRP/trkA positive fibers that normally constitute the majority of sensory fibers that innervate the bone. S100A12 drug opioid 17498818 The chronic administration of butoxamine with morphine reduced or eliminated the normally observed up regulation of CGRP and SP in spinal cord and DRG tissues. S100A12 drug opioid 17395382 Sustained exposure to opioid agonists such as morphine increases levels of calcitonin gene related peptide (CGRP) in the spinal dorsal horn, a response implicated in the development of opioid tolerance and physical dependence. S100A12 addiction dependence 17395382 Sustained exposure to opioid agonists such as morphine increases levels of calcitonin gene related peptide (CGRP) in the spinal dorsal horn, a response implicated in the development of opioid tolerance and physical dependence. S100A12 drug cannabinoid 17395382 Recent evidence suggests that both the opioid induced increase in CGRP and the development of opioid physical dependence are suppressed by blockade of spinal cannabinoid (CB1) receptors. S100A12 drug opioid 17395382 Recent evidence suggests that both the opioid induced increase in CGRP and the development of opioid physical dependence are suppressed by blockade of spinal cannabinoid (CB1) receptors. S100A12 addiction dependence 17395382 Recent evidence suggests that both the opioid induced increase in CGRP and the development of opioid physical dependence are suppressed by blockade of spinal cannabinoid (CB1) receptors. S100A12 drug opioid 17395382 In another set of experiments, chronic administration of spinal morphine (15 microg) once daily for 5 days produced a similar loss of analgesic effect and a marked increase in CGRP immunoreactivity in the superficial laminae of the dorsal horn.

BCHE drug cocaine 10681384 In the first experiment, the addition of BChE to squirrel monkey plasma in vitro reduced the half life of cocaine by over 80%, decreased the production of the metabolic product benzoylecgonine, and increased ecgonine methyl ester formation.

JUNB drug opioid 7755894 The c fos and junB immediate early genes (IEGs) were induced in neurons of the medial and ventral striatum following administration of morphine. JUNB drug opioid 7755894 The striatal induction of c fos and junB mRNA and Fos protein was blocked by naloxone, the D1 dopamine (DA) receptor antagonists, SCH23390 and SCH39166, and the N methyl D aspartate (NMDA) glutamate receptor antagonist, MK801. JUNB drug opioid 7755894 SCH23390 and MK801 did not block morphine induction of c fos and junB in septum. JUNB drug amphetamine 7755894 Since the pattern of the morphine induction of c fos and junB in striatum and nucleus accumbens was similar to that observed with cocaine and amphetamine [2,18,45,51], these data support current concepts that limbic striatum and nucleus accumbens are among the brain regions that mediate drug abuse [9,10,23,27,49].

JUNB drug cocaine 7969045 One early cellular response to cocaine administration is a brain region specific alteration in the transcriptional pattern of immediate early genes belonging to the Fos/Jun family of nucleotide sequence specific [activator protein 1 (AP 1)] DNA binding proteins. JUNB drug cocaine 7969045 The work described here compares cocaine induced transcriptional regulation of immediate early gene mRNA levels, as well as AP 1 DNA binding activity, within the striatum and cerebellum. JUNB drug cocaine 7969045 Gel retention analysis using antibodies to the various Fos and Jun proteins was used to characterize cocaine dependent alterations in the composition of striatal and cerebellar AP 1 DNA binding complexes. JUNB drug cocaine 7969045 In striatum, cocaine increases the relative levels of c Fos, Fos B, Jun B, and Jun D proteins that bind the AP 1 DNA sequence element, whereas in the cerebellum only c Fos and Jun D binding activities are increased.

JUNB drug opioid 8078918 SCH23390 and MK801 did not block morphine induction of c fos and junB in septum. JUNB drug amphetamine 8078918 Since the morphine induction of c fos and junB in striatum and nucleus accumbens (NA) was similar to that observed with cocaine and amphetamine, these data support current concepts that limbic striatum and NA are among the brain regions that mediate drug abuse.

GRIN2A drug opioid 32032749 Western blotting and qRT PCR revealed no differences in NR2A subunit expression among heroin exposure, heroin withdrawal, and control group rats; in contrast, expression of NR2B was significantly higher in the heroin exposure group, whereas expression levels of NR2C and NR2D were significantly higher in the heroin withdrawal group relative to the controls.

GRIN2A drug opioid 31941720 All these results suggest that chronic pain status and lack of morphine analgesia are independent to each other, and the lack of morphine analgesia is mediated by an activation of NR2A NMDA receptor system. GRIN2A drug alcohol 31473305 However, we observed a correlation of α1 and γ2 subunits induced by taurine, while in the alcohol group there was a correlation between α4 and GluN2A.

GRIN2A addiction intoxication 31056842 Memory and plasticity impairment after binge drinking in adolescent rat hippocampus: GluN2A/GluN2B NMDA receptor subunits imbalance through HDAC2. GRIN2A addiction intoxication 31056842 In conclusion, the memory impairing effects of two binge like EtOH exposure involve NMDA receptor dependent LTD deficits due to a GluN2A/GluN2B imbalance resulting from changes in GluN2B expression induced by HDAC2. GRIN2A addiction withdrawal 30733663 We then analyzed the expression levels of presynaptic (vGlut1, vGlut2, CB1 receptor, synaptophysin) and postsynaptic (PSD95, GluN1, GluN2A, GluN2B, GluA1, GluA2, mGluR1 and mGluR5) proteins after 7 days EtOH incubation or after EtOH withdrawal. GRIN2A drug cocaine 30165076 Injection of GSK J4 selectively reversed this cocaine induced increase of NR2A expression and synaptic function, suggesting that mal adaptation of cocaine induced synaptic plasticity in mPFC largely underlies KDM6B mediated cocaine associated memory. GRIN2A drug cocaine 30144237 In cocaine naïve animals, SERT removal led to reduced baseline Hb mRNA levels of critical determinants of glutamate transmission, such as SLC1A2, the main glutamate transporter and N methyl D aspartate (Grin1, Grin2A and Grin2B) as well as α amino 3 hydroxy 5 methyl 4 isoxazolepropionic acid (Gria1 and Gria2) receptor subunits, with no changes in the scaffolding protein Dlg4.

GRIN2A addiction dependence 29953905 Taken together, these data add to mounting evidence supporting GluN2A containing NMDARs as a mechanism underlying relative risk for developing EtOH dependence after repeated EtOH exposure.

GRIN2A addiction addiction 29788757 Discussion and conclusions Transcriptional levels of GluN2A and GluN2D subunits in online computer game addicts are similar to our previously reported data of opioid addiction and are not different from the control group. GRIN2A addiction addiction 29766293 Data obtained using Western blotting technique showed a significant increase in the level of GluN1 and GluN2B, but not in GluN2A subunits in all the three regions (mPFC, lPFC, and OFC) of men whom suffered from addiction as compared to the appropriate controls. GRIN2A addiction addiction 29766293 These findings showed a novel role for GluN1, GluN2B subunits, rather than the GluN2A subunit of NMDARs, in the pathophysiology of addiction and suggested their role in the drug induced plasticity of NMDARs. GRIN2A drug opioid 29754475 The results of this study show that the NAc specific knockdown of RGS4 significantly increased the behaviors associated with morphine and did so by phosphorylation of the GluR1 (Ser831) and NR2A (Tyr1325) glutamate receptors in the NAc.

GRIN2A drug alcohol 29704590 The increased expression levels of GRIN2A and GRIN2B following ethanol abstinence were reversed with a higher dose of NAC (100 mg/kg) treatment. GRIN2A drug alcohol 29704590 In conclusion, the results of the study reveal that NAC has remarkable protective effects in the alcohol abstinence induced depression by modulating alcohol markers, serotonin levels and GRIN2A, GRIN2B gene expression of NMDAR signaling pathway in rats. GRIN2A drug amphetamine 29441405 In rats that reinstated methamphetamine seeking, these altered electrophysiological properties of GCNs were associated with enhanced expression of Fos, GluN2A subunits and PSD95 and reduced expression of GABAA subunits in the DG and enhanced expression of synaptic PSD in the molecular layer.

GRIN2A addiction relapse 28585567 Role of Src Family Kinases in BDNF Mediated Suppression of Cocaine Seeking and Prevention of Cocaine Induced ERK, GluN2A, and GluN2B Dephosphorylation in the Prelimbic Cortex. GRIN2A drug cocaine 28585567 As previously reported, infusion of BDNF into the PrL cortex blocked cocaine SA induced dephosphorylation of ERK, GluN2A, and GluN2B containing receptors. GRIN2A drug cocaine 28123030 We further show that the cocaine facilitation of t LTP induction is caused by sensitized D1 cAMP/protein kinase A dopamine signaling in pyramidal neurons, which then pathologically recruits voltage gated l type Ca2+ channels that synergize with GluN2A containing NMDA receptors to drive t LTP at extended timing. GRIN2A drug cocaine 28042872 Infralimbic GluN2A Containing NMDA Receptors Modulate Reconsolidation of Cocaine Self Administration Memory. GRIN2A addiction relapse 28042872 These results indicate that IL mPFC GluN2A containing NMDArs modulate reconsolidation, and suggest a novel treatment strategy, as reducing cue reactivity could limit relapse susceptibility. GRIN2A addiction reward 27267684 During a first testing phase, adult male rats implanted with bilateral ventral midbrain cannulae were injected every second day for three days with D [Tyr11]neurotensin (1.5 nmol/side), the preferred NMDA GluN2A/B antagonist, CPP (40 or 120 pmol/side), the selective GluN2B antagonist, Ro04 5595 (200 or 1200 pmol/side), CPP (40 or 120 pmol/side) + D [Tyr11]neurotensin (1.5 nmol/side) or Ro04 5595 (200 or 1200 pmol/side) + D [Tyr11]neurotensin (1.5 nmol/side) and locomotor activity was measured immediately after the injection. GRIN2A drug amphetamine 27267684 These results support the hypothesis that neurotensin is stimulating glutamate neurotransmission to initiate neural changes that sub serve amphetamine sensitization and that glutamate is acting on NMDA receptors that are mostly likely composed of GluN2A, but not GluN2B, subunits. GRIN2A addiction sensitization 27267684 These results support the hypothesis that neurotensin is stimulating glutamate neurotransmission to initiate neural changes that sub serve amphetamine sensitization and that glutamate is acting on NMDA receptors that are mostly likely composed of GluN2A, but not GluN2B, subunits. GRIN2A drug cocaine 27765467 In the present study, infusion of the GluN2A containing NMDA receptor antagonist, TCN 201, or the GluN2B containing NMDA receptor antagonist, Ro 25 6981, into the prelimbic cortex of rats blocked the suppressive effect of BDNF on cocaine seeking.

GRIN2A drug cocaine 27765467 During early withdrawal from cocaine self administration, tyrosine phosphorylation of ERK, GluN2A, and GluN2B in the prelimbic cortex was reduced and this reduction of phospho proteins was prevented by intra prelimbic BDNF infusion.

GRIN2A drug amphetamine 26366944 Moreover, METH inhibited mitogen activated protein kinase (MAPK) signaling activity and altered expression of the N methyl d aspartate (NMDA) receptor subunits NR2A and NR2B as well as calcium/calmodulin dependent protein kinase II (CaMKII). GRIN2A drug alcohol 26289945 The aim of the current study was to determine genotype effects of four single nucleotide polymorphisms (SNPs) in the genes of the N Methyl d aspartate receptor (GRIN1, GRIN2A, GRIN2C) and kainate receptor (GRIK1), which have been previously associated with alcoholism, on behavior, neural cue reactivity and drinking outcome.

GRIN2A drug alcohol 26266540 In the present study, we used human embryonic stem cell (hESC) derived cortical neurons as in vitro cellular models to investigate alcohol induced expression changes of genes involved in alcohol metabolism (ALDH2), anti apoptosis (BCL2 and CCND2), neurotransmission (NMDA receptor subunit genes: GRIN1, GRIN2A, GRIN2B, and GRIN2D), calcium channel activity (ITPR2), or transcriptional repression (JARID2). GRIN2A drug alcohol 26266540 After a 7 day ethanol (50 mM) exposure followed by a 24 hour ethanol withdrawal treatment, five of the above nine genes (including all four NMDA receptor subunit genes) were highly upregulated (GRIN1: 1.93 fold, P = 0.003; GRIN2A: 1.40 fold, P = 0.003; GRIN2B: 1.75 fold, P = 0.002; GRIN2D: 1.86 fold, P = 0.048; BCL2: 1.34 fold, P = 0.031), and the results of GRIN1, GRIN2A, and GRIN2B survived multiple comparison correction.

GRIN2A addiction relapse 25855177 Context induced reinstatement was associated with increased expression of the immediate early genes Fos and FosB and the NMDA receptor subunit gene Grin2a in only Fos positive neurons. GRIN2A drug alcohol 25800798 On the other hand ethanol significantly decreased NR2A and NR2B mRNAs expression, and increase GABAA mRNA expression. GRIN2A drug amphetamine 25752339 We also found that METH altered the expression of the N methyl d aspartate (NMDA) receptor subunits NR2A (79.6%) and NR2B (126.7%) and Ca(2+) /calmodulin dependent protein kinase II (CAMKII) (74.0%). GRIN2A drug alcohol 25743187 In the medial prefrontal cortex, 2.5g/kg ethanol decreased mRNA expression of brain derived neurotrophic factor, NMDA NR2A subunit, mGluR8 receptor, Homer1, the glutamate transporters SLC1a1 and SLC1a6 and Srr. GRIN2A drug cocaine 25539508 An overall decrease was observed in the mRNA expression of the glutamate synthesizing gene kidney type glutaminase (KGA), the metabotropic glutamate receptors (mGluR3 and GluR), and subunits of NMDA ionotropic receptors (NR1, NR2A, NR2B and NR2C) after acute cocaine administration, while mice repeatedly exposed to cocaine only displayed an increase in NR2C. GRIN2A drug alcohol 25538565 Thus, in the caudate we found reduced levels of mRNAs encoding the GluN2A glutamate receptor and the δ, ε, and ρ2 GABA A receptor subunits, and increased levels of the mRNAs encoding GluD1, GluD2, and GABA A γ1 subunits in the alcoholics as compared to controls. GRIN2A drug cocaine 25408547 The present study focused on metabotropic glutamatergic receptors type 5 (mGluR(5)) and N methyl D aspartate receptor subunits (NMDAR: GluN1, GluN2A, GluN2B) proteins during cocaine self administration and after 10 day of extinction training in rats. GRIN2A drug cocaine 25408547 Our results revealed that cocaine self administration selectively increased GluN1 and GluN2A subunit in the rat hippocampus and dorsal striatum, respectively, while mGluR(5) protein expression was similarly increased in the dorsal striatum of both experimental groups. GRIN2A drug cocaine 25408547 Withdrawal from both contingent and non contingent cocaine delivery induced parallel increases in prefrontal cortical GluN2A protein expression, hippocampal mGluR(5), and GluN1 protein expression as well as in accumbal GluN1 subunit expression, while the mGluR(5) expression was reduced in the prefrontal cortex. GRIN2A addiction withdrawal 25408547 Withdrawal from both contingent and non contingent cocaine delivery induced parallel increases in prefrontal cortical GluN2A protein expression, hippocampal mGluR(5), and GluN1 protein expression as well as in accumbal GluN1 subunit expression, while the mGluR(5) expression was reduced in the prefrontal cortex. GRIN2A drug cocaine 25408547 Extinction training in animals with a history of cocaine self administration resulted in an elevation of the hippocampal GluN2A/GluN2B subunits and accumbal mGluR(5), and in a 50 % decrease of mGluR(5) protein expression in the dorsal striatum.

GRIN2A drug opioid 25121622 Activation of the D1 receptors inhibits the long term potentiation in vivo induced by acute morphine administration through a D1 GluN2A interaction in the nucleus accumbens. GRIN2A drug opioid 25121622 Here, we report that acute in vivo morphine administration induces the long term potentiation (Mor LTP) of field excitatory postsynaptic potentials at the prefrontal cortex to nucleus accumbens shell synapses, and this process requires the activation of GluN2A containing N methyl D aspartate receptors. GRIN2A addiction addiction 25121622 These results indicate that the activation of D1 receptors modulates Mor LTP by the direct D1 GluN2A interaction at the prefrontal cortex to nucleus accumbens shell synapses and might play a role in addiction related plastic alterations. GRIN2A drug cocaine 24847958 However, both GluN2A and GluN2B subunit expression in the nucleus accumbens increased following cocaine self administration, and this increased expression was relatively resistant to modulation by extinction. GRIN2A drug cocaine 24832868 In addition, repeated cocaine altered NMDA receptor subunit expression in the ventral hippocampus, reducing the NR2A : NR2B subunit ratio. GRIN2A drug cocaine 24832868 This was associated with reduced ventral hippocampal NR2A:NR2B subunit ratio, suggesting that repeated exposure to cocaine produces changes in hippocampal NMDA receptor composition that lead to enhanced ventral hippocampus nucleus accumbens communication. GRIN2A drug alcohol 24523671 Out of the 16 glutamate receptor subunits, mRNAs encoding two AMPA [2 amino 3 (3 hydroxy 5 methyl isoxazol 4 yl)propanoic acid] receptor subunits GluA2 and GluA3; three kainate receptor subunits GluK2, GluK3 and GluK5 and five NMDA (N methyl D aspartate) receptor subunits GluN1, GluN2A, GluN2C, GluN2D, and GluN3A were significantly increased in the HP DG region in alcoholics.

GRIN2A addiction withdrawal 20853509 The data therefore provide direct evidence for reduced synaptic GluN1/GluN2B receptors and preservation of GluN1/GluN2A receptors in the CA1 stratum radiatum region during BZ withdrawal. GRIN2A drug alcohol 20807241 Repeated alcohol treatment (8 × 2 g/kg) increased the expression of Group1 metabotropic glutamate receptors, the NR2a/b subunits of the N methyl D aspartate receptor, Homer2a/b, as well as the activated forms of protein kinase C (PKC) epsilon and phosphoinositol 3 kinase within ventral, but not dorsal, striatum. GRIN2A drug alcohol 20807241 Regardless of prior alcohol experience, C57BL/6J mice exhibited higher accumbens levels of mGluR1/5, Homer2a/b, NR2a and activated kinases vs. DBA2/J mice, whereas an alcohol induced rise in dorsal striatum mGluR1/5 expression was observed only in C57BL/6J mice.

GRIN2A drug cocaine 19046409 Here we show that application of cocaine both in slices and in vivo induced an increase in tyrosine phosphorylation of the NR2A, but not the NR2B subunit of the NMDAR in juvenile rats. GRIN2A drug cocaine 19046409 Cocaine induced an increase in the activity of both Fyn and Src kinases, and the Src protein tyrosine kinase (Src PTKs) inhibitor, 4 amino 5 (4 chlorophenyl) 7 (t butyl)pyrazolo[3,4 d]pyrimidine (PP2), abolished both cocaine induced increase in tyrosine phosphorylation of the NR2A subunit and the increase in the expression of NR1, NR2A, and NR2B in the VTA. GRIN2A drug cocaine 19046409 Taken together, these results suggest that acute cocaine induced an increase in the expression of NMDAR subunits and enhanced tyrosine phosphorylation of NR2A containing NMDAR through members of the Src PTKs.

GRIN2A drug opioid 18851757 These findings indicate that impaired NMDAR dependent neuronal plasticity following repeated morphine injection in PSD 93 knockout mice is attributed to PSD 93 deletion induced alterations of synaptic NR2A and NR2B expression in dorsal horn and forebrain cortex neurons. GRIN2A drug alcohol 18849153 Fyn tyrosine kinase is a member of the Scr family that phosphorylates the NR2A and NR2B subunits of the NMDA receptors reducing the inhibitory effects of ethanol and therefore may regulate the individual sensitivity to ethanol.

GRIN2A addiction dependence 18606955 Analysis of study 1 revealed that NR2A and MGLUR5 have the greatest relevance for human alcohol dependence among the genes selected with odds ratios of 2.35 and 1.69, respectively. GRIN2A drug alcohol 18606955 Replication analysis in study 2 confirmed an association of alcohol dependence with NR2A (odds ratio, 2.01) but showed no association with MGLUR5. GRIN2A addiction dependence 18606955 Replication analysis in study 2 confirmed an association of alcohol dependence with NR2A (odds ratio, 2.01) but showed no association with MGLUR5. GRIN2A drug alcohol 18606955 Combined analysis of study 1 and study 2 exhibited a more significant association on the Cochran Mantel Haenszel test (P < .001) for NR2A; NR2A was associated with positive family history, early onset of alcoholism, and maximum number of drinks in adults as well as risky drinking patterns in adolescents.

GRIN2A addiction dependence 18606955 Genetic variations in NR2A have the greatest relevance for human alcohol dependence among the glutamatergic genes selected for their known alteration of alcohol effects in animal models. GRIN2A drug psychedelics 18419818 The aim of the present study was to investigate the effect of repeated intermittent MDMA administration upon gene transcript expression of the glutamate transporters (EAAT1, EAAT2 1, EAAT2 2), the glutamate receptor subunits of AMPA (GluR1, GluR2, GluR3), the glutamate receptor subunits of NMDA (NR1, NR2A and NR2B), as well as metabotropic glutamate receptors (mGluR1, mGluR2, mGluR3, mGluR5) in six different brain regions. GRIN2A drug opioid 18391508 In the genetic section of the study, results of quantitative real time RT PCR clearly indicated that morphine sensitization increased the expression of NMDA receptor subunits mRNA in the amygdala (NR1 by 104% and NR2A by 85%), while the other areas of the brain were unaffected.

GRIN2A drug opioid 18374314 Morphine withdrawal affects both delayed escape behaviour in Morris water maze and hippocampal NR2A/2B expression ratio. GRIN2A addiction withdrawal 18374314 Morphine withdrawal affects both delayed escape behaviour in Morris water maze and hippocampal NR2A/2B expression ratio. GRIN2A drug opioid 18374314 Here, we examined whether and how morphine withdrawal influenced delayed escape behaviour and NR2A/2B expression ratio of hippocampal synaptosomes. GRIN2A addiction withdrawal 18374314 Here, we examined whether and how morphine withdrawal influenced delayed escape behaviour and NR2A/2B expression ratio of hippocampal synaptosomes. GRIN2A addiction withdrawal 18374314 We found that both delayed escape behaviour and NR2A/2B expression ratio showed an inverted U curve and peaked on 4 day withdrawal during a 20 day withdrawal period. GRIN2A addiction withdrawal 18374314 Furthermore, treatment of the glucocorticoid receptor antagonist RU38486 for 3 days reduced delayed escape behaviour and NR2A/2B ratio on 4 day withdrawal to a level similar to those of 18 h withdrawal. GRIN2A addiction withdrawal 18374314 In contrast, elevated platform stress enabled delayed escape behaviour of 18 h withdrawal to a higher level similar to that of 4 day withdrawal, but had no significant effect on the NR2A/2B ratio. GRIN2A drug alcohol 18358639 The relative mRNA expression of exon 5 inclusion/exclusion variants of the NR1 subunit, and the relative expression of NR2A, NR2B and NR2C subunits was examined in rats subjected to long term free choice, alcohol self administration with repeated alcohol deprivation phases. GRIN2A drug cocaine 17950706 In both species, withdrawal from repeated cocaine administration down regulated Homer1b/c and Homer2a/b within the shell, but not the core, of the nucleus accumbens (NAC), and the reduced Homer levels were accompanied by decreases in mGluR1a, NR2a and NR2b. GRIN2A addiction withdrawal 17950706 In both species, withdrawal from repeated cocaine administration down regulated Homer1b/c and Homer2a/b within the shell, but not the core, of the nucleus accumbens (NAC), and the reduced Homer levels were accompanied by decreases in mGluR1a, NR2a and NR2b. GRIN2A drug cocaine 17950706 Cocaine induced increases in Homer1b/c, Homer2a/b, mGluR1a and NR2a were observed in the hippocampus of both rats and mice, while in dorsal striatum, NR2a levels were elevated but Homer and Group1 mGluR levels were unchanged. GRIN2A drug alcohol 17625498 While genetic removal of NR2A did not alter the magnitude of ethanol inhibition, pharmacological blockade of NR2B rendered synaptically activated NMDARs insensitive to ethanol inhibition. GRIN2A drug opioid 17321516 We have previously shown, using radioligand binding studies, that N methyl d aspartate (NMDA) NR1 and NR2A receptor subunits density was decreased in the forebrain of morphine dependent rats. GRIN2A drug opioid 17321516 In morphine dependent rats, the expression of NR1 and NR2A subunits protein, as determined by Western blotting with NMDA receptor subunit antibodies, were decreased in frontal cortex and hippocampus but significantly increased in the nucleus accumbens. GRIN2A drug alcohol 17156796 Under these conditions, mRNA and protein levels of NR1, NR2A and NR2B subunits did not change in the spinal cord of chronic ethanol fed rats. GRIN2A drug alcohol 16835771 Ethanol related behaviors in mice lacking the NMDA receptor NR2A subunit. GRIN2A drug alcohol 16835771 In the current study, we assessed the relative roles of NMDA subunits via phenotypic assessment of ethanol related behaviors in NR2A knockout (KO) mice. GRIN2A drug alcohol 16835771 Results demonstrated that NR2A KO and heterozygous mice failed to show evidence of ethanol induced conditioned place preference. GRIN2A drug alcohol 16835771 Results suggest that the loss of NR2A subunit containing NMDA receptors impairs the ability to form or express learned reward related responses to ethanol and causes deficits in motor coordination. GRIN2A addiction reward 16835771 Results suggest that the loss of NR2A subunit containing NMDA receptors impairs the ability to form or express learned reward related responses to ethanol and causes deficits in motor coordination. GRIN2A drug alcohol 16835771 However, the loss of NR2A does not alter other measures of acute ethanol intoxication or ethanol consumption, possibly implicating other NMDA subunits in these effects. GRIN2A addiction intoxication 16835771 However, the loss of NR2A does not alter other measures of acute ethanol intoxication or ethanol consumption, possibly implicating other NMDA subunits in these effects. GRIN2A drug opioid 16453311 In this study we examined the effects of chronic morphine administration on gene and protein expression of three major NMDA receptors subunits (NR1, NR2A, and NR2B) in NAcc and CeA. GRIN2A drug alcohol 16396741 There were also no significant changes observed in any of the NMDA subunit mRNAs, although there was a trend toward greater NR2A mRNA expression during chronic ethanol exposure. GRIN2A drug alcohol 16396741 Like the mRNA measures, chronic ethanol exposure did influence NR2A protein levels but the effects were modest. GRIN2A drug alcohol 16009711 Here we show that exposure of hippocampal neurons to ethanol increases the internalization of the NR2A but not NR2B subunit of the NMDAR via the endocytic pathway. GRIN2A drug alcohol 16009711 We further observed that ethanol exposure results in NR2A endocytosis through the activation of H Ras and the inhibition of the tyrosine kinase Src. GRIN2A drug alcohol 16009711 Importantly, ethanol treatment alters functional subunit composition from NR2A/NR2B to mainly NR2B containing NMDARs. GRIN2A drug alcohol 16009352 The ethanol sensitive NMDA receptor subunits NR1, NR2A and NR2B were quantified by Western immunoblot analysis. GRIN2A drug alcohol 16009352 Exposure to ethanol (50 mM) caused an increase in the levels of NR1 (137 +/ 11% of untreated control, P = 0.009), NR2A (128 +/ 14%, P = 0.022) and NR2B (136 +/ 19%, P = 0.012). GRIN2A drug alcohol 16009352 Coincubation with memantine (10 microM) completely blocked the ethanol induced up regulation of NR1 (102 +/ 4%), NR2A (95 +/ 7%) and NR2B (105 +/ 13%). GRIN2A drug cocaine 15953359 In the basolateral amygdala, GluR1 but not GluR2 levels were increased on days 1 and 30, NR2A levels were increased on day 1, and NR2B levels were decreased on day 30 of withdrawal from cocaine. GRIN2A addiction withdrawal 15953359 In the basolateral amygdala, GluR1 but not GluR2 levels were increased on days 1 and 30, NR2A levels were increased on day 1, and NR2B levels were decreased on day 30 of withdrawal from cocaine. GRIN2A drug cocaine 15953359 In the central amygdala, GluR2 but not GluR1 levels were increased on days 1 and 30, NR1 levels were increased on day 30 and NR2A or NR2B levels were not altered after withdrawal from cocaine. GRIN2A addiction withdrawal 15953359 In the central amygdala, GluR2 but not GluR1 levels were increased on days 1 and 30, NR1 levels were increased on day 30 and NR2A or NR2B levels were not altered after withdrawal from cocaine. GRIN2A addiction withdrawal 15919065 Western blot analysis of NMDA receptor subunit expression showed that, at 7 days of withdrawal, the level of protein for NR2A and NR2B subunits was elevated in the CA1 region of hippocampal slices from CIE treated animals compared with slices from age matched controls. GRIN2A drug alcohol 15902902 Fyn kinase does not reduce ethanol inhibition of zinc insensitive NR2A containing N methyl D aspartate receptors. GRIN2A drug opioid 15542739 By a novel electroporation technique to deliver the receptor into the brain of knockout mice, we succeeded in determining the specific locus for the site of anti opioid (through GluRepsilon1 or NR2A) action. GRIN2A drug opioid 15464026 The increased levels of extracellular glutamate, NMDA receptor zeta subunit (NR1) mRNA, NMDA receptor epsilon 1 subunit (NR2A) protein, phosphorylated Ca(2+)/calmodulin kinase II (p CaMKII) protein, c fos mRNA, c Fos protein, are observed in the specific brain areas of mice and/or rats showing signs of naloxone precipitated withdrawal.

GRIN2A drug opioid 15464026 In the NMDA receptor deficient mice, the NR2A knockout mice show the marked loss of typical withdrawal abstinence behaviors precipitated by naloxone. GRIN2A addiction withdrawal 15464026 In the NMDA receptor deficient mice, the NR2A knockout mice show the marked loss of typical withdrawal abstinence behaviors precipitated by naloxone. GRIN2A drug opioid 15263066 Taken together with our recent molecular studies, our data are consistent with a shift away from NMDA receptor subunit (NR) NR2B and 2C function toward increased NR2A subunit expression or function after chronic morphine, a process that could alter excitability and integrative properties and may represent a neuroadaptation of NAcc medium spiny neurons underlying morphine dependence.

GRIN2A addiction withdrawal 14745308 The up regulation of NR2A during EtOH withdrawal is consistent with compensatory changes to prolonged inhibition of the NMDAR. GRIN2A drug opioid 14684447 Therefore, we examined the effects of morphine dependence on electrophysiological properties of NMDARs in freshly isolated NAcc neurons and on expression of mRNA coding for NR2A C subunits using single cell RT PCR.

GRIN2A drug nicotine 14666123 NMDA NR2A/B subunits were affected by nicotine, but without age related differences. GRIN2A drug alcohol 14615013 Ethanol inhibition of recombinant NR1/2A receptors: effects of heavy metal chelators and a zinc insensitive NR2A mutant. GRIN2A drug alcohol 14615013 Results from previous studies with recombinant NMDA receptors have demonstrated that subunit composition influences the ethanol sensitivity of NMDA receptors, with NR2A containing receptors often showing greater inhibition by ethanol than shown by those containing other NR2 subunits. GRIN2A drug alcohol 14615013 In this study, we examined the effects of ethanol on NR1/NR2A receptors expressed in human embryonic kidney 293 (HEK 293) cells recorded under conditions in which the effects of zinc are minimized. GRIN2A drug alcohol 14615013 These results support the suggestion that low levels of zinc present in experimental solutions may affect the apparent ethanol sensitivity of NMDA receptors containing the NR2A subunit. GRIN2A drug alcohol 14534353 Most GAD , presumed projection neurons expressed both NR2A and NR2B mRNAs, and this profile did not change during chronic ethanol exposure. GRIN2A drug cocaine 12325043 Repeated cocaine administration differentially affects NMDA receptor subunit (NR1, NR2A C) mRNAs in rat brain. GRIN2A drug cocaine 12325043 injections of cocaine (20 mg/kg) on subunit mRNAs of N methyl D aspartate (NMDA) receptors (NR1/NR2A 2C) in the rat brain by in situ hybridization using phosphor screen analysis. GRIN2A drug alcohol 11696675 Unexpectedly, we found that expression of NR1 (including the expression of NR1 subunits containing the N1, C1, and C2 inserts), NR2A, NR2B, NR2C, GluR1, GluR2/3, GluR5, GluR6/7, and KA2 subunits was not altered in hippocampal homogenates from ethanol exposed rats. GRIN2A drug alcohol 11530236 Altered effects of ethanol in NR2A(DeltaC/DeltaC) mice expressing C terminally truncated NR2A subunit of NMDA receptor. GRIN2A drug alcohol 11530236 To investigate whether the C terminus of the NR2A subunit is involved in determining the sensitivity of NMDA receptors to ethanol we compared the effects of ethanol in vitro on NMDA mediated field excitatory postsynaptic potentials (fEPSPs) in the CA1 and dentate gyrus (DG) of adult male NR2A(DeltaC/DeltaC) mice lacking the C terminus of NR2A subunit and in their parental strain C57Bl/6. GRIN2A drug alcohol 11530236 We also tested the in vivo effects of a hypnotic dose of ethanol in C57Bl/6 and NR2A(DeltaC/DeltaC) mice and their F2 offspring. GRIN2A drug alcohol 11530236 Ethanol (100 mM) in the presence of ifenprodil inhibited the CA1 NR2A mediated component of NMDA fEPSPs two times more in NR2A(DeltaC/DeltaC) than in C57Bl/6. GRIN2A drug alcohol 11530236 Ethanol inhibition of the CA1 NR2B mediated component was five to seven times lower in NR2A(DeltaC/DeltaC) than in C57Bl/6. GRIN2A drug alcohol 11530236 A second administration of ethanol 7 days after the initial injection revealed an increased ethanol sensitivity of NR2A(DeltaC/DeltaC) and F2(DeltaC/DeltaC) mice including a shortened time to loss of righting reflex and an increased sleep time. GRIN2A drug alcohol 11530236 The sensitization of NR2A(DeltaC/DeltaC) mice to alcohol was not accompanied by an altered ethanol sensitivity of NMDA fEPSPs recorded in vitro. GRIN2A addiction sensitization 11530236 The sensitization of NR2A(DeltaC/DeltaC) mice to alcohol was not accompanied by an altered ethanol sensitivity of NMDA fEPSPs recorded in vitro. GRIN2A drug alcohol 11530236 Our data are consistent with the inhibitory action of ethanol on NMDA receptors being mediated by a site other than the intracellular C terminus of the NR2A subunit. GRIN2A drug alcohol 11530236 The altered sensitivities to ethanol of both NR2A and NR2B mediated responses in the CA1 of NR2A(DeltaC/DeltaC) imply that NR2A and NR2B subunit containing NMDA receptors may be linked by a common target of ethanol. GRIN2A drug psychedelics 11438305 These results suggest that NR1/NR2A subunit containing NMDA antagonism may be critical for the production of the ketamine cue. GRIN2A drug alcohol 11369029 In HEK 293 cells, acamprosate showed almost no effect on NR1 1a/NR2A or NR1 1a/NR2B recombinants (IC(50)s not calculated). GRIN2A drug opioid 11233291 treatment with a specific antibody against the carboxyl terminal region of the NR2B subunit abolishes the morphine induced place preference, whereas antibodies against the NR1 and NR2A subunits do not affect the rewarding effect of morphine, indicating that the blockade of the NR2B subunit suppresses the development of the morphine induced rewarding effect. GRIN2A addiction withdrawal 11152389 The NR2A mRNA was significantly decreased in the CA1 and CA3 of hippocampus in tolerant rats and increased in the cerebral cortex and dentate gyrus in butorphanol withdrawal rats. GRIN2A addiction withdrawal 11152389 No changes of NR1, NR2A, NR2C subunit mRNA in the cerebellar granule cell layer were observed in either butorphanol tolerant or withdrawal rats. GRIN2A drug alcohol 10405999 The NR1/NR2A and NR1/NR2B combinations are preferentially sensitive to ethanol inhibition. GRIN2A drug alcohol 10225371 NR2A subunit levels were significantly increased only in hippocampus from ethanol dependent male rats, whereas NR2B subunit levels significantly increased in cerebral cortex of both female and male rats. GRIN2A drug alcohol 10082858 Levels of NR2A, NR2C, NR1 pan and both 3' NR1 insert mRNAs from the ethanol treated groups did not alter compared with the pair fed control group. GRIN2A drug opioid 9988122 Using in situ hybridization techniques, the effects of chronic morphine treatment on the expression of mRNAs encoding the NMDA receptor subunits NRI, NR2A, and NR2B were investigated. GRIN2A drug opioid 9988122 The expression of NR2A and NR2B subunit mRNAs did not change after morphine treatment in any brain region. GRIN2A drug alcohol 9685652 We investigated the effect of chronic ethanol administration and its withdrawal on the polypeptide levels of NMDA receptor subunits such as NR1, NR2A, and NR2B in the rat cerebral cortex and hippocampus using Western blot analysis technique. GRIN2A addiction withdrawal 9685652 We investigated the effect of chronic ethanol administration and its withdrawal on the polypeptide levels of NMDA receptor subunits such as NR1, NR2A, and NR2B in the rat cerebral cortex and hippocampus using Western blot analysis technique. GRIN2A drug alcohol 9685652 Our results indicate that chronic ethanol treatment upregulates NMDA receptor subunits NR1, NR2A, and NR2B (approximately 35%). GRIN2A drug benzodiazepine 9543260 The protein levels of the NR1 and NR2B, but not NR2A, subunits were significantly increased in diazepam withdrawn rats compared to those in control rats. GRIN2A drug alcohol 9145911 Immunoblot analysis of expression of NR1, NR2A, and NR2B receptor subunits showed no difference between control and chronic ethanol treated cultures. GRIN2A drug alcohol 8840015 Our current work demonstrates that chronic ethanol ingestion by mice, which results in the generation of physical dependence, also produces increases in the NMDA receptor NR1 subunit protein in the hippocampus and cerebellum (approximately 50% and 95%, respectively), and produces increases in the NR2A subunit protein in the hippocampus and cortex (approximately 25% and 40%, respectively). GRIN2A addiction dependence 8840015 Our current work demonstrates that chronic ethanol ingestion by mice, which results in the generation of physical dependence, also produces increases in the NMDA receptor NR1 subunit protein in the hippocampus and cerebellum (approximately 50% and 95%, respectively), and produces increases in the NR2A subunit protein in the hippocampus and cortex (approximately 25% and 40%, respectively).

CYP2B6 drug opioid 32416296 An indicator for cytochrome P450 enzymes which have the most fundamental role in methadone metabolism in the liver. CYP2B6 drug benzodiazepine 32354497 To clarify the cause of cardiogenic shock, we performed whole exome sequencing and screened relative single nucleotide variants of 2 cytochrome P450 (CYP) isoforms, CYP3A4 and CYP3A5, which play a dominant role in the metabolic elimination of midazolam. CYP2B6 drug opioid 32302325 Although CYP3A4 was conventionally considered the principal methadone metabolizing enzyme, more recent data have identified CYP2B6 as the principal enzyme. CYP2B6 drug opioid 32302325 We assessed hepatic fibrosis and steatosis by transient elastography and CYP2B6 alleles, principally responsible for methadone metabolism. CYP2B6 drug opioid 32302325 CYP2B6 loss of function (LOF) alleles significantly affected (S) methadone metabolism (p = 0.012). CYP2B6 drug opioid 32302325 Although the principal methadone metabolizing enzyme remains controversial, our results suggest that sex, CYP2B6 genotype, and BMI should be incorporated into multivariate models to create methadone dosing algorithms. CYP2B6 drug nicotine 32247097 Nicotine is mainly metabolized (C oxidation) in the liver to cotinine by the cytochrome P450 enzyme system. CYP2B6 drug opioid 31820437 The data suggest that P450 enzymatic activity impacts the clearance of methadone in virtual adults and neonates, while the contribution of cardiac output may be negligible. CYP2B6 drug opioid 31820437 Understanding maturational and/or pharmacogenetic changes in cytochrome P450 enzymatic activity may further explain the large PK variability of methadone in newborns with NAS and will help individualized treatment. CYP2B6 drug alcohol 31646907 The role of oxidative metabolism of ethanol by alcohol dehydrogenase, cytochrome P450 2E1, and aldehyde dehydrogenase, as well as the impact of genetic polymorphism in its physiopathology are also highlighted. CYP2B6 drug nicotine 31628204 During tobacco and e cigarette use, nicotine is mainly metabolized in the human liver by cytochrome P450 2A6 (CYP2A6). CYP2B6 drug opioid 31263758 We find that mitragynine is converted in vitro in both mouse and human liver preparations to the much more potent mu opioid receptor agonist 7 hydroxymitragynine and that this conversion is mediated by cytochrome P450 3A isoforms.

CYP2B6 drug nicotine 31187118 Prolonging the Reduction of Nicotine Self Administration in Rats by Coadministering Chronic Nicotine With Amitifadine, a Triple Monoamine Reuptake Inhibitor With CYP2B6 Inhibitory Actions. CYP2B6 drug nicotine 31187118 This study was conducted to determine if the combination of chronic nicotine with amitifadine, a triple monoamine reuptake inhibitor with CYP2B inhibitory effects, would reduce nicotine self administration to a greater extent than either alone or placebo. CYP2B6 drug nicotine 31187118 The improved efficacy of the amitifadine and nicotine combination may be potentiated by amitifadine's inhibitory effects on CYP2B, which slows nicotine metabolism. CYP2B6 drug benzodiazepine 31147443 Simulation of the binding of the ligands midazolam, bromocriptine, testosterone, and ketoconazole to P450 3A4 was consistent with an induced fit or a conformational selection model, but the concentration dependence of binding rates for varying both P450 3A4 and midazolam concentrations revealed discordance in the parameters, indicative of conformational selection. CYP2B6 addiction dependence 31147443 Simulation of the binding of the ligands midazolam, bromocriptine, testosterone, and ketoconazole to P450 3A4 was consistent with an induced fit or a conformational selection model, but the concentration dependence of binding rates for varying both P450 3A4 and midazolam concentrations revealed discordance in the parameters, indicative of conformational selection. CYP2B6 drug benzodiazepine 31023150 As midazolam is an established marker substance for cytochrome P450 3A activity, this single arm prospective trial was designed to obtain a 4 h pharmacokinetic profile of midazolam after oral administration of a 10 µg dose from each enrolled patient.

CYP2B6 drug opioid 30907440 Relevance of CYP2B6 and CYP2D6 genotypes to methadone pharmacokinetics and response in the OPAL study. CYP2B6 drug opioid 30907440 Our study aimed to evaluate the impacts of the cytochrome P450 (CYP) 2B6 G516T and CYP2D6 genetic polymorphisms on pharmacokinetic and clinical parameters in patients receiving methadone maintenance treatment. CYP2B6 drug opioid 30907440 When comparing the three CYP2B6 genotype groups, the methadone (R) and (S) methadone enantiomer concentrations/doses (concentrations relative to doses) were different (P = .029, P = .0019). CYP2B6 drug opioid 30907440 On multivariate analysis, neither the CYP2B6 genotype nor the CYP2D6 phenotype explained the (R) methadone concentration/dose values (P = .92; P = .86); the (S) methadone concentration/dose values (P = .052; P = .95 [although there was a difference between the TT group and GT and GG groups {P = .019}]); or opiate cessation (P = .12; P = .90).

CYP2B6 drug nicotine 28092945 Nicotine Metabolism and Smoking: Ethnic Differences in the Role of P450 2A6. CYP2B6 drug nicotine 28092945 Nicotine is the primary addictive agent in tobacco, and P450 2A6 (gene name: CYP2A6) is the primary catalyst of nicotine metabolism. CYP2B6 addiction addiction 28092945 Nicotine is the primary addictive agent in tobacco, and P450 2A6 (gene name: CYP2A6) is the primary catalyst of nicotine metabolism. CYP2B6 drug nicotine 28092945 In other ethnic groups, it has been challenging to confirm a direct link between P450 2A6 mediated nicotine metabolism and the risk of lung cancer. CYP2B6 drug nicotine 28092945 This challenge is due in part to the difficulty in accurately quantifying smoking dose and accurately predicting or measuring P450 2A6 mediated nicotine metabolism. CYP2B6 drug nicotine 28092945 Biomarkers of nicotine metabolism and smoking exposure, including the ratio of trans 3 hydroxycotine to cotinine, a measure of P450 2A6 activity and plasma cotinine, or urinary total nicotine equivalents (the sum of nicotine and six metabolites) as measures of exposure are useful for addressing this challenge. CYP2B6 drug nicotine 28092945 Variation in metabolism pathways, other than those catalyzed by P450 2A6, can impact biomarkers of both nicotine metabolism and dose. CYP2B6 drug nicotine 28032407 Cytochrome P450 2A6 (CYP2A6) encodes the enzyme responsible for the majority of nicotine metabolism.

CYP2B6 drug nicotine 27230546 Brain CYP2B induction can decrease nicotine levels in the brain. CYP2B6 drug nicotine 27230546 Nicotine can be metabolized by the enzyme CYP2B; brain CYP2B is higher in rats and monkeys treated with nicotine, and in human smokers. CYP2B6 drug nicotine 27230546 A 7 day nicotine treatment increased CYP2B expression in rat brain but not liver, and decreased the behavioral response and brain levels (ex vivo) to the CYP2B substrate propofol. CYP2B6 drug nicotine 27230546 However, the effect of CYP2B induction on the time course and levels of circulating brain nicotine in vivo has not been demonstrated. CYP2B6 drug nicotine 27230546 There was a significant time x treatment interaction (p = 0.01); peak nicotine levels (15 45 minutes post injection) were lower after treatment (p = 0.04) consistent with CYP2B induction.

CYP2B6 drug nicotine 25652250 CYP2B can metabolize nicotine, the main psychoactive ingredient in cigarettes; if altered brain CYP2B activity can influence nicotine brain levels, it could influence nicotine mediated behaviors. CYP2B6 drug nicotine 25652250 To investigate this, a mechanism based inhibitor selective for CYP2B, C8 xanthate (20 μg), was administered intracerebroventricularly (ICV) into the brain of rats, and 22 h later, nicotine levels were measured by in vivo microdialysis following nicotine (150 μg/kg intravenous).

CYP2B6 drug alcohol 9328319 Because it had been reported that chlormethiazole inhibits the alcohol inducible cytochrome P450 2E1 in rat liver, we investigated the in vivo and in vitro effect of this drug on cytochrome P450 2E1 in human beings. CYP2B6 drug alcohol 9328319 The 6 hydroxychlorzoxazone chlorzoxazone blood concentration ratio, reflecting the cytochrome P450 2E1 activity, was determined in 10 controls and in 24 alcoholic patients who had entered a hospital for detoxification.

CYP2B6 drug alcohol 9054307 The ethanol inducible cytochrome P450 2E1 plays a key role in its generation, favoured itself by an increase in the "redox active" fraction of intracellular non heme iron. CYP2B6 drug alcohol 8812268 Metabolism of 1,2 difluoroethane by cytochrome P450 (most likely CYP2E1) is suspected because pretreatment of rats or mice with SKF 525F, disulfiram, or dimethyl sulfoxide prevented or delayed the toxicity observed in rats not pretreated. CYP2B6 drug alcohol 8691480 Recent evidence suggests that intraneuronal metabolism of ethanol by catalase/H2O2 and an ethanol inducible form of cytochrome P450 together generate acetaldehyde and oxygen radicals including the hydroxyl radical (HO.).

CYP2B6 addiction withdrawal 7786308 Induction of these P450 isoforms persisted for several days following withdrawal. CYP2B6 addiction intoxication 7655131 This man's delirium is consistent with fluoxetine intoxication, which appears to have resulted from inhibition of hepatic cytochrome P450 metabolism by clarithromycin. CYP2B6 drug alcohol 8014872 Ethanol inducible cytochrome P450 (CYP) 2E1 (CYP2E1) is responsible for the metabolism of many xenobiotics which exert toxic effects in humans. CYP2B6 drug cocaine 8277979 Some exceptions to this rule were found: HCBD significantly increased T15 alpha OH, PROD and EROD activities in C57Bl/6 mice, whereas cocaine caused a significant stimulation of T15 alpha OH and PROD in DBA/2 mice, It is concluded that i) different hepatoxins cause different types of liver injury and responses of the monooxygenase complex ("hepatotoxinspecific finger prints"), ii) although DBA/2 and C57Bl/6 mice responded rather similarly to hepatotoxins, also with respect to P450 content and most MO activities, they displayed a profound difference in the behaviour of COH activity, and iii) within the P450 superfamily, the regulation of COH activity seems to be rather unique, also when compared to its structurally close enzyme, testosterone 15 alpha hydroxylase.

CYP2B6 drug alcohol 1811956 Most notably, THF is an inhibitor of a number of cytochrome P450 (P450) dependent mixed function oxidase activities, with a particular affinity for the alcohol induced isozyme (P450IIE1). CYP2B6 drug opioid 2178849 The majority of these interactions arise because phenytoin is a potent inducer of cytochrome P450 microsomal enzymes, and therefore may increase the clearance of drugs which are extensively metabolised; drugs affected include carbamazepine, theophylline, methadone, prednisolone, dexamethasone, metyrapone and several cardiac antiarrhythmic agents. CYP2B6 drug alcohol 2537602 Temperature dependence of the microsomal oxidation of ethanol by cytochrome P450 and hydroxyl radical dependent reactions. CYP2B6 addiction dependence 2537602 Temperature dependence of the microsomal oxidation of ethanol by cytochrome P450 and hydroxyl radical dependent reactions. CYP2B6 drug alcohol 2537602 Arrhenius plots of the .OH dependent oxidation of ethanol by both microsomal preparations were linear with energies of activation (about 7 kcal/mol) that were considerably lower than values found for the P450 dependent pathway. CYP2B6 drug alcohol 2537602 These results suggest that, at least in terms of activation energy, the increase in microsomal ethanol oxidation by pyrazole treatment is not associated with any apparent change in the overall mechanism or rate limiting step for ethanol oxidation but likely reflects induction of a P450 isozyme with increased activity toward ethanol. CYP2B6 drug alcohol 2537602 The lower activation energy for the .OH dependent oxidation of ethanol suggests that different steps are rate limiting for oxidation of ethanol by .OH and by P450, which may reflect the different enzyme components of the microsomal electron transfer system involved in these reactions.

DRD3 drug cocaine 18790725 Drd3 agents also block the ability of conditioned cues to reinstate responding for cocaine or food. DRD3 addiction reward 18790725 Published results suggest that Drd3 plays a more important role in the expression than in the acquisition of a CPP or conditioned motor activity. DRD3 addiction reward 18790725 The mechanism mediating the role of Drd3 in the control of responding by conditioned incentive stimuli remains unknown but it has been found that Drd3 receptors increase in number in the nucleus accumbens during conditioning. DRD3 addiction reward 18790725 Perhaps Drd3 participates in the molecular mechanisms underlying the role of dopamine and of dopamine receptor subtypes in reward related incentive learning.

DRD3 addiction dependence 17155853 This review considers the potential use of the dopamine D(3) receptor (DRD3) as a novel therapeutic target for the treatment of tobacco dependence. DRD3 addiction relapse 17155853 Among the 5 dopamine receptors identified, the DRD3 is located in the nucleus accumbens, ventral tegmental area and amygdala: 3 brain structures that are implicated in the motivational control of drug seeking behaviour and drug conditioning processes. DRD3 addiction dependence 17155853 Several highly selective DRD3 ligands have recently been evaluated in preclinical models of drug dependence. DRD3 drug nicotine 17155853 In contrast to nicotine replacement therapy, varenicline and bupropion (which are currently used for the treatment of smokers), DRD3 antagonists do not seem to produce nicotine like effects in experimental animals and, therefore, may not substitute for nicotine or alleviate nicotine withdrawal symptoms in human smokers.

DRD3 addiction dependence 16759339 No association of dopamine receptor sensitivity in vivo with genetic predisposition for alcoholism and DRD2/DRD3 gene polymorphisms in alcohol dependence. DRD3 drug alcohol 16759339 This study sought to examine dopamine receptor sensitivity among alcoholics in vivo and to explore whether this sensitivity might be associated with functional variations of dopamine D2 (DRD2) and D3 (DRD3) receptor genes along with a genetic predisposition for alcoholism as reflected by an alcohol dependent first degree relative. DRD3 drug alcohol 16759339 We analyzed the 141C Ins/Del polymorphism in the promoter region of the DRD2 gene and the Ser9Gly (BalI) polymorphism in exon 1 of the DRD3 gene in 74 alcohol dependent Caucasian men with or without genetic predisposition for alcoholism. DRD3 drug alcohol 16759339 Given the explorative and preliminary character of this investigation, we cannot provide evidence that in alcohol dependent Caucasian men a genetic predisposition for alcoholism along with functional variants of the DRD2 and DRD3 genes are associated with differences in dopamine receptor sensitivity. DRD3 addiction dependence 15963538 Dopamine D(3) receptors (DRD3) are predominantly expressed in the nucleus accumbens, but also in the ventral tegmental area and in the amygdala, brain structures implicated in drug dependence. DRD3 addiction dependence 15963538 Moreover, converging pharmacological, human post mortem and genetic studies have suggested the involvement of the DRD3 in drug dependence. DRD3 addiction reward 15963538 However, recent studies using highly selective DRD3 ligands and the DRD3 deficient mice have revealed that the DRD3 is not implicated in the direct reinforcing effects of drugs of abuse. DRD3 addiction relapse 15963538 The DRD3 strongly modulates the influence of these environmental stimuli on drug seeking behavior. DRD3 addiction relapse 15963538 All these findings suggest that DRD3 ligands may represent a useful strategy for decreasing relapse in abstinent drug abusers.

ABCB1 drug opioid 29414996 Many opioids are a substrate for p glycoprotein (p gp), an efflux transporter at the blood brain barrier (BBB). ABCB1 drug opioid 29414996 Increased p gp is associated with a decreased central nervous system uptake and analgesic efficacy of morphine. ABCB1 drug opioid 29414996 Our laboratory previously found that acute peripheral inflammatory pain (PIP) induces p gp trafficking from the nucleus to the luminal surface of endothelial cells making up the BBB concomitant with increased p gp activity and decreased morphine analgesic efficacy. ABCB1 drug opioid 29414996 In the current study, we tested whether PIP induced p gp trafficking could contribute to decreased opioid efficacy in morphine tolerant rats. ABCB1 drug opioid 29414996 PIP induced p gp trafficking away from nuclear stores showed a 2 fold increase in morphine tolerant rats. ABCB1 drug opioid 29414996 This observation suggests that p gp trafficking contributes to the decreased morphine analgesic effects in morphine tolerant rats experiencing an acute pain stimulus. ABCB1 drug opioid 29414996 Attenuating p gp trafficking during an acute pain stimulus could improve pain management by increasing the amount of opioid that could reach CNS analgesic targets and decrease the need for the dose escalation that is a serious challenge in pain management.

ABCB1 addiction dependence 28917442 ABCB1 polymorphisms are known to modify drug pharmacokinetics but have yet to be studied for their role in generating and maintaining cannabis dependence. ABCB1 drug cannabinoid 28917442 The objective of this study is to determine if ABCB1 C3435T (rs1045642) polymorphism may modulate Δ9 Tetrahydrocannabinol (THC) blood levels in a sample of heavy cannabis users. ABCB1 drug cannabinoid 28917442 Each underwent clinical evaluation, cannabis blood metabolite dosage (THC, 11 OH THC, and THC COOH) and genotyping of ABCB1 C3435T polymorphism. ABCB1 drug cannabinoid 28917442 Our results show that ABCB1 C3435T polymorphism may modulate serum THC levels in chronic heavy cannabis users. ABCB1 drug amphetamine 28893794 Transporter function was examined after exposure of Tat with or without methamphetamine using the P gp substrate rhodamine 123 and also using the dual P gp/MRP 1 substrate and protease inhibitor atazanavir. ABCB1 drug amphetamine 28893794 Neither Tat nor methamphetamine significantly altered P gp expression. ABCB1 drug amphetamine 28893794 However, Tat plus methamphetamine exposure significantly increased rhodamine 123 accumulation within brain endothelial cells, suggesting that treatment inhibited or impaired P gp function. ABCB1 drug cannabinoid 28272498 As risperidone and its active metabolite are excellent substrates of the ABC transporter P glycoprotein (P gp), we hypothesized that THC might increase P gp expression at the blood brain barrier (BBB) and thus enhance efflux of risperidone and its metabolite from brain tissue. ABCB1 drug cannabinoid 28272498 Furthermore, we demonstrated that THC exposure increased P gp expression in various brain regions important to risperidone's antipsychotic action. ABCB1 drug cannabinoid 28272498 Our results imply that clozapine or non P gp substrate antipsychotic drugs may be better first line treatments for schizophrenia patients with a history of cannabis use.

ABCB1 drug opioid 27061230 To examine whether certain genotypes were associated with this, we examined the frequencies of 29 SNPs located in candidate genes related to opioid pharmacology: ABCB1, OPRM1, UGT2B7, CYP3A5, CYP2B6, CYP2C19, CYP2D6, COMT, KCNJ6 and SCN9A in 274 deceased patients with OA (DOA), 309 living patients with OA (LOA) and in 394 healthy volunteers (HV). ABCB1 drug opioid 27061230 The main hypothesis of the study was that subjects homozygous for the variant 3435T in ABCB1 (rs1045642) occur more frequently in DOA than in LOA and HV because morphine and methadone more readily cross the blood barrier in these subjects due to a lower efflux transporter activity of the ABCB1 (p glycoprotein) transporter.

ABCB1 drug opioid 23527191 To investigate the mechanism of P gp's interaction with methadone, as well as the effect of genetic variants on the interaction, Flp In™ 293 cells stably transfected with various genotypes of human P gp were established in the present study. ABCB1 drug opioid 23527191 Utilizing rhodamine 123 efflux assay and calcein AM uptake study, methadone was demonstrated to be an inhibitor of wild type human P gp via non competitive kinetic (IC50 = 2.17±0.10 µM), while the variant type human P gp, P gp with 1236T 2677T 3435T genotype and P gp with 1236T 2677A 3435T genotype, showed less inhibition potency (IC50 = 2.97±0.09 µM and 4.43±1.10 µM, respectively) via uncompetitive kinetics.

ABCB1 drug opioid 22845665 This study investigates the rate and extent to which P gp and breast cancer resistance protein (Bcrp) increase at the rat blood brain barrier following subchronic morphine treatment. ABCB1 drug opioid 22845665 The gene and protein expression of P gp and Bcrp in morphine treated and control rats were compared by qRT PCR and western blotting. ABCB1 drug opioid 22845665 The levels of Mdr1a and Bcrp mRNAs were not significantly modified 6 h post morphine, but the Mdr1a mRNA increased 1.4 fold and Bcrp mRNA 2.4 fold at 24 h. P gp and Bcrp protein expression in brain microvessels was unchanged 6 h post morphine and increased 1.5 fold at 24 h. This effect was more pronounced in large vessels than in microvessels. ABCB1 drug opioid 22845665 However, extracellular morphine concentrations of 0.01 10 μM did not modify the expressions of the MDR1 and BCRP genes in hCMEC/D3 human endothelial brain cells in vitro. ABCB1 drug opioid 22845665 MK 801 (NMDA antagonist) and meloxicam (cyclo oxygenase 2 inhibitor) given after morphine treatment completely blocked P gp and Bcrp up regulation. ABCB1 drug opioid 22845665 Thus, morphine does not directly stimulate P gp and Bcrp expression by the brain endothelium, but glutamate released during morphine withdrawal may do so by activating the NMDA/cyclo oxygenase 2 cascade.

ABCB1 drug opioid 21050174 Herein, we describe current in vitro and in vivo methodology available to analyze interactions between opioids and P gp and critically analyze P gp data associated with six commonly used mu opioids to include morphine, methadone, loperamide, meperidine, oxycodone, and fentanyl. ABCB1 drug opioid 21050174 Recent studies focused on the development of opioids lacking P gp substrate activity are explored, concentrating on structure activity relationships to develop an optimal opioid analgesic lacking this systems level contribution to tolerance development.

ADORA2A addiction addiction 32492952 In this review, we updated the view on the brain D2 receptor complexes with adenosine (A)2A receptors (A2AR) and discussed the role of A2AR in different aspects of addiction phenotypes in laboratory animal procedures that permit the highly complex syndrome of human drug addiction. ADORA2A drug cocaine 32492952 We presented the current knowledge on the neurochemical in vivo and ex vivo mechanisms related to cocaine use disorder (CUD) and discussed future research directions for A2AR heteromeric complexes in SUD. ADORA2A drug cocaine 32338111 Furthermore, cocaine exposure differentially altered promoter methylation levels of A2AR, Ppp1cc, and Taar7b in the NAc and LHb of HE and LE rats. ADORA2A drug cocaine 32124388 Upon cocaine self administration, this antagonistic A2AR D2R interaction disappeared in the dorsal striatum. ADORA2A drug cocaine 32124388 In the current experiments, it was tested whether such modifications in the antagonistic A2AR D2R receptor receptor interactions can develop also after an acute systemic injection of a low cocaine dose (1 mg/kg; sc). ADORA2A drug cocaine 32124388 Competition dopamine receptor binding experiments demonstrated that in the acute cocaine group, the A2AR agonist CGS 21680 produced significantly larger increases in the D2R Ki, High values (reduction of high affinity) versus the saline injected (i.e. ADORA2A drug cocaine 32124388 The molecular mechanism involved in the acute cocaine induced increase in the antagonistic allosteric A2AR D2R receptor receptor interactions may be an increased formation of higher order complexes A2AR D2R sigma1R in which cocaine by binding to the sigma1R protomer also allosterically enhances the inhibitory A2AR D2R interaction in this receptor complex. ADORA2A drug cannabinoid 31973708 It has been hypothesized that heteromers of adenosine A2A receptors (A2AR) and cannabinoid CB1 receptors (CB1R) localized in glutamatergic nerve terminals mediate the integration of adenosine and endocannabinoid signaling involved in the modulation of striatal excitatory neurotransmission. ADORA2A addiction dependence 31973708 A dependence of A2AR signaling for the Gi protein mediated CB1R signaling was described as one of its main biochemical characteristics. ADORA2A drug cannabinoid 31973708 We demonstrate that the well established cannabinoid induced inhibition of striatal glutamate release can mostly be explained by a CB1R mediated counteraction of the A2AR mediated constitutive activation of adenylyl cyclase in the A2AR CB1R heteromer. ADORA2A drug cocaine 31816953 A2AR Transmembrane 2 Peptide Administration Disrupts the A2AR A2AR Homoreceptor but Not the A2AR D2R Heteroreceptor Complex: Lack of Actions on Rodent Cocaine Self Administration. ADORA2A drug cocaine 31816953 It was previously demonstrated that rat adenosine A2AR transmembrane V peptide administration into the nucleus accumbens enhances cocaine self administration through disruption of the A2AR dopamine (D2R) heteroreceptor complex of this region. ADORA2A drug cocaine 31816953 A2AR TM2 was proposed to be part of the of the receptor interface of the A2AR homomer instead and was therefore tested in the current article for effects on rat cocaine self administration using rat A2AR synthetic TM2 peptide bilaterally injected into the nucleus accumbens. ADORA2A drug cocaine 31816953 The injected A2AR TM2 peptide failed to significantly counteract the inhibitory action of the A2AR agonist CGS 21680 (0.1 mg/Kg) on cocaine self administration. ADORA2A drug cocaine 31816953 The results indicate that the accumbal A2AR A2AR homomeric complexes are not involved in mediating the A2AR agonist induced inhibition of cocaine self administration. ADORA2A drug cocaine 31782100 In cocaine self administration, highly significant increases were also induced by OSU 6162 in the A2AR D2R heteroreceptor complexes in the nucleus accumbens shell versus vehicle treated rats. ADORA2A drug cocaine 31782100 Furthermore, ex vivo, the A2AR agonist CGS21680 (100 nM) produced a marked and significant increase of the D2R Ki high values in the OSU 6162 treated versus vehicle treated rats under maintenance of cocaine self administration. ADORA2A drug cocaine 31782100 These results indicate a substantial increase in the inhibitory allosteric A2AR D2R interactions following cocaine self administration upon activation by the A2AR agonist ex vivo. ADORA2A drug cocaine 31782100 The current results indicate that OSU 6162 via its high affinity for the Sigma1R may increase the number of accumbal shell D2R Sigma1R and A2AR D2R heteroreceptor complexes associated with further increases in the antagonistic A2AR D2R interactions in cocaine self administration.

ADORA2A drug cocaine 27872762 In contrast, the allosteric brake on the D2R protomer signaling in the A2AR D2R heterocomplex of the dorsal striatopallidal GABA neurons is lost upon cocaine self administration. ADORA2A drug cocaine 26987369 In the current study behavioral and biochemical experiments were performed to study changes in the allosteric A2AR D2R interactions in the ventral and dorsal striatum after cocaine self administration versus corresponding yoked saline control. ADORA2A drug cocaine 26987369 The results therefore support the hypothesis that A2AR agonists can at least in part counteract the motivational actions of cocaine. ADORA2A drug cocaine 26987369 In contrast, in the dorsal striatum the CGS 21680 induced antagonistic modulation in the D2 likeR agonist high affinity state was abolished after cocaine self administration versus the yoked saline group probably due to a local dysfunction/disruption of the A2AR D2 like R heteroreceptor complexes.

CCKBR addiction addiction 8947930 Association of enkephalin catabolism inhibitors and CCK B antagonists: a potential use in the management of pain and opioid addiction. CCKBR drug opioid 8947930 The overlapping distribution of opioid and cholecystokinin (CCK) peptides and their receptors (mu and delta opioid receptors; CCK A and CCK B receptors) in the central nervous system have led to a large number of studies aimed at clarifying the functional relationships between these two neuropeptides.

CCKBR addiction withdrawal 7597123 These data contrast with reports that CCKB antagonists alleviate behavioural benzodiazepine (BZ) withdrawal symptoms considered to be indicative of "anxiogenesis". CCKBR addiction withdrawal 7597123 Presumably, such positive effects of CCKB antagonists are due to "functional antagonism", with enhanced anxiety during BZ withdrawal being attenuated by anxiolytic actions of CCKB antagonists. CCKBR addiction withdrawal 7597123 Collectively, studies with CCKB antagonists and other agents involving a number of different BZ withdrawal signs suggest that BZ withdrawal is a heterogeneous syndrome, with various different underlying mechanisms.

NODAL drug alcohol 32319345 Mechanistically, alcohol inhibited extracellular signal related kinase activity, a nodal signaling kinase activating physiology hypertrophy. NODAL addiction relapse 31710020 In multivariable analysis, surgical procedure, tumor size, nodal stage, and subtype were still significant factors for relapse free survival (RFS) while only subtype acted as the significant factor for overall survival (OS). NODAL drug alcohol 31315270 Confocal analysis of nodal domains, flanked by immunofluorescent labeled contactin associated protein (Caspr) clusters, indicated that alcohol drinking reduced nodal length to width ratios in layers II/III of the Cg1 in both sexes. NODAL drug alcohol 31315270 Despite sex differences in the underlying cause (larger diameter axons after alcohol in males vs. shorter nodal lengths after alcohol in females), reduced nodal ratios could have important implications for the speed and integrity of neural transmission along these axons in both males and females.

CCL4 drug alcohol 32390833 The present study aimed to explore the hepatoprotective effects of acidic hydrolysates of polysaccharide extracted from the marine clam M. veneriformis (Ah MVPS) against ethanol and CCl4 induced liver damage. CCL4 drug alcohol 32390833 They can suppress membrane destruction in boundaries and the collapse of reticular scaffolds of injured mouse hepatocytes and can substantially reduce the inflammatory extent of liver tissue aroused by excessive intake of ethanol or CCl4. CCL4 addiction intoxication 32050489 This study confirms the ability of quercetin loaded niosomes to reverse CCl4 intoxication and to carry out an antioxidant effect. CCL4 drug alcohol 31919559 Genome wide expression and TRN analysis were performed time dependently in mouse liver after acute injury by CCl4 (2 h, 8 h, 1, 2, 4, 6, 8, 16 days), as well as lipopolysaccharide (LPS, 24 h) and compared to publicly available data after tunicamycin exposure (mouse, 6 h), hepatocellular carcinoma (HCC, mouse), and human chronic liver disease (non alcoholic fatty liver, HBV infection and HCC). CCL4 addiction intoxication 31919559 Acute CCl4 intoxication induced expression of gene clusters enriched for inflammation and stress signaling that peaked between 2 and 24 h, accompanied by a decrease of mature liver functions, particularly metabolic genes. CCL4 drug alcohol 31870920 In addition, chronic CCl4 and acute LPS treatment inhibited hepatic ADH1 expression and activity, leading to increases in blood and liver ethanol concentrations. CCL4 drug cocaine 31557508 In rats treated repeatedly with cocaine (10 mg/kg × 4 days, IP), CCR5 gene expression was upregulated in the nucleus accumbens and ventral tegmental area but mRNA levels of CCR5 ligands (i.e., CCL3, CCL4 and CCL5) were not affected. CCL4 drug alcohol 31188634 Combination of CCl4 with alcoholic and metabolic injuries mimics human liver fibrosis. CCL4 drug alcohol 31188634 Ethanol in drinking water (16%) or Western diet (WD) were administered for 7 wk in mice either alone or in combination with CCl4 intoxications.

CCL4 drug alcohol 31188634 The relationship pattern between fibrosis, proliferation, and inflammation of human ALD was mostly similar in mice treated with CCl4 and ethanol. CCL4 addiction intoxication 31188634 The combination of CCl4 intoxication with WD validates previous data suggesting it as an appropriate model for human nonalcoholic steatohepatitis. CCL4 drug alcohol 31188634 Especially, CCl4 plus ethanol for 7 wk induces ALD in mice, providing a model suitable for further basic research and drug testing.NEW & NOTEWORTHY Alcoholic fatty liver disease with significant fibrosis is generated within 7 wk using carbon tetrachloride as a fibrosis accelerator and administering gradually ethanol (up to 16%) in mice. CCL4 drug alcohol 30787972 112 male C57BL/6 mice were randomly divided into 14 groups: control group (CG), CCL4 group (CTG), low/medium/high dose of Euonymus alatus ethanol extracts (EAE), catechin (CA), dihydroquercetin (DHQ) and kaempferol (KA) groups. CCL4 addiction dependence 30787972 Results showed that EAE/CA/DHQ/KA prevented increases in liver index, ALT, AST, α SMA, collagen I, TβR1, Smad2/3, TNF α and p NF κB caused by CCL4 in dose dependence, they also improved the liver morphology, decreased inflammatory cell infiltration and collagenous fiber in dose dependence, CA' efficacy was best in mice; in LX 2, CA also decreased the expression of α SMA, collagen I, TGF β, Smad2/3. CCL4 drug alcohol 30529260 Despite its low bioavailability, its hepatoprotective effects have been studied in various protocols of hepatotoxicity including acetaminophen, alcohol, lindane, carbon tetrachloride (CCL4), diethylnitrosamine and heavy metals induced hepatotoxicities. CCL4 drug alcohol 29862216 Metadoxine (pyridoxine pyrrolidone carboxylate) is considered to be a beneficial agent for the treatment of experimental hepatotoxicity due to alcohol, CCl4, and bile duct ligation. CCL4 addiction intoxication 29404036 The extract and silymarin treated animal groups showed significant decrease in activities of different biochemical parameters like serum glutamic oxaloacetic transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), which were elevated by carbon tetrachloride (CCl4) intoxication. CCL4 drug alcohol 29274031 After alcohol exposure, C C motif chemokine ligand 4 (CCL4) was significantly increased in female AE pups on PD5 and PD8. CCL4 drug alcohol 29274031 After alcohol exposure, C C motif chemokine ligand 4 (CCL4) was significantly increased in female AE pups on PD5 and PD8. CCL4 drug opioid 29146238 Protein array analyses revealed only minor changes to cytokine profiles when morphine was administered acutely or repeatedly; however, 24 h post morphine administration, the expression of several cytokines was greatly increased, including endogenous CCR5 chemokine ligands (CCL3, CCL4, and CCL5), as well as CCL2. CCL4 addiction intoxication 28706418 NAR administration prevented increases in ALT, AP, γ GTP, and GPx enzymatic activity; depletion of GSH and glycogen; and increases in LPO and collagen produced by chronic CCl4 intoxication (P < 0.05). CCL4 addiction intoxication 28653915 Hepatoprotective and reno potective effect of Sargassum species was investigated in rats against carbon tetrachloride (CCl4) and acetaminophen (AAP) intoxication.

CCL4 drug alcohol 28501008 Ethanol extract and its dichloromethane fraction of Alpinia oxyphylla Miquel exhibited hepatoprotective effects against CCl4 induced oxidative damage in vitro and in vivo with the involvement of Nrf2. CCL4 drug alcohol 28501008 This study aimed to investigate the protective effects of ethanol extract (EE) and its dichloromethane fraction (DM) of A. oxyphylla, which are rich in phenolic compounds, against CCl4 induced hepatic injury in vitro and in vivo. CCL4 addiction intoxication 28501008 Liver histopathology revealed that EE and DM attenuated the incidence of liver lesions triggered by CCl4 intoxication. CCL4 drug alcohol 28489378 Efficient reduction of CCl4 took place upon exposure to 350 nm photons of aqueous solutions containing sulfonated poly(ether etherketone) (SPEEK) as a sensitizer and either poly(vinyl alcohol) (PVA) or HCO2H/HCO2 buffer. CCL4 addiction dependence 28489378 The dependence of r(Cl ) on (I0)1/2, where I0 is the light intensity, and the occurrence of postirradiation formation of Cl through the reduction of CCl4 in the dark are further evidence that the photoreaction proceeded by a chain process. CCL4 addiction intoxication 28100224 It left beyond doubt that a flower of L. speciosa is a reservoir of antioxidant and hepatoprotective agents capable of reversing the damage inflicted by CCl4 intoxication. CCL4 drug alcohol 26996510 Furthermore, both alcohol exposed and SI animals had increased levels of pro inflammatory cytokines IL 1β, TNF α, CD11b, and CCL4; in addition, CCL4 was significantly increased in alcohol exposed animals compared to SI as well. CCL4 drug alcohol 23683793 Among the 75 patients in each group the percentage still retained on naltrexone treatment at six months was: N/G 26.7%, N/P 19.7% (p=0.258 to N/G), P/G 6.7% (p<0.05 to both N groups), and P/P 10.7% (p=0.013 to N+G). CCL4 drug alcohol 24363682 After inducing hepatic damage, group III served as control for CCl4; and groups IV VI received different doses of Ficus carica ethanol extract (200, 400 and 800 mg/kg) prior to intoxication with CCl4.

CCL4 drug alcohol 15992118 Liver injury caused by hepatotoxins, such as carbon tetrachloride (CCl4), ethanol, and acetaminophen (APAP), is characterised by varying degrees of hepatocyte degeneration and cell death via either apoptosis or necrosis. CCL4 drug alcohol 15945353 Preventive administration of the balm and hydrolysates to animals subjected to an intoxications by 40% alcohol and CCl4 normalized clinical diagnostic parameters of liver and blood plasma of experimental animals. CCL4 drug nicotine 11762131 Drugs currently used such as paracetamol, anesthetics (enflurane, halothane), industrial solvents (benzene or its derivatives), halogenated solvents (CCl4, trichlorethylene) and nitrosamines which are present in food or tobacco smoke are included. CCL4 drug alcohol 11450593 Since the authors reported the presence of collagenase in the liver as well as its increased activity in the early stage of hepatic fibrosis and its reduced activity in advanced fibrosis in rats induced by chronic CCl4 intoxication, in baboons fed alcohol chronically and in patients with alcoholic fibrosis, other investigators have demonstrated the same tendency of collagenase activity biologically and histochemically.

CCL4 drug alcohol 11327524 ES of Nux MT in CCl4 showed a red shift when 90% ethanol was added indicating molecular complexation and charge transfer interaction between ethanol and Nux compounds. CCL4 drug alcohol 10759217 Since authors first reported increased activity of interstitial collagenase in the early stage of hepatic fibrosis in rats induced by chronic CCl4 intoxication, in baboons fed alcohol chronically and in patients with alcoholic fibrosis, other investigators have also demonstrated increased activity biologically and histochemically.

CCL4 drug opioid 10654191 In this study, chemotaxis of monkey leukocytes was evaluated using human chemokines IL 8 (interleukin 8), MIP 1 beta and RANTES as the chemoattractants, and the effects of micro opioid receptor agonists, morphine, DAMGO, methadone and endomorphine, on the efficiency of chemotaxis were examined. CCL4 addiction intoxication 10467456 The n BuOH and EtOAc fractions had the greatest hepatoprotective effects on CCl4 induced liver injury; in contrast, the CHCl3 fraction was most potent against D GalN intoxication, which is comparable to silymarin, as a recognized hepatoprotective drug. CCL4 drug alcohol 8948088 We have studied the hepatic microsomal metabolism of ethanol (MEOS), CYP2E1 expression and catalytic activity, and the response to phenobarbital (PB) induction or CCl4 challenge in rats of either sex genetically selected for their preference (P) or aversion (NP) for ethanol. CCL4 addiction aversion 8948088 We have studied the hepatic microsomal metabolism of ethanol (MEOS), CYP2E1 expression and catalytic activity, and the response to phenobarbital (PB) induction or CCl4 challenge in rats of either sex genetically selected for their preference (P) or aversion (NP) for ethanol. CCL4 drug alcohol 8937429 Animals treated with CCl4 and ethanol for 9 weeks showed hepatic injury as demonstrated by 2.5 and 2 fold increases in serum alanine aminotransferase and alkaline phosphatase activities, respectively. CCL4 drug alcohol 7487375 Group IV was treated with CCl4 as group III, but drinking water was substituted by ethanol solutions with increasing concentrations as in the group II. CCL4 addiction intoxication 7487375 Samples of blood, liver and spleen were taken 24 h after the third acute CCl4 intoxication. CCL4 addiction intoxication 7487375 Acute CCl4 intoxication (group III) significantly decreased IFN production in liver and spleen cells isolated 24 h after the last CCl4 injection. CCL4 drug alcohol 7487375 Combined CCl4 and ethanol administration affected very strongly IFN production (group IV). CCL4 drug alcohol 8277979 Acute effects of a single intraperitoneal dose of allyl alcohol (AA, 64 mg/kg), dimethylnitrosamine (DMNA, 30 mg/kg), hexachlorobutadiene (HCBD, 50 mg/kg), carbon tetrachloride (CCl4, 24 mg/kg), cocaine (60 mg/kg) and pyrazole (300 mg/kg) on the hepatic histology and monooxygenases in DBA/2 and C57Bl/6 strains of mice were investigated. CCL4 drug cocaine 8277979 Acute effects of a single intraperitoneal dose of allyl alcohol (AA, 64 mg/kg), dimethylnitrosamine (DMNA, 30 mg/kg), hexachlorobutadiene (HCBD, 50 mg/kg), carbon tetrachloride (CCl4, 24 mg/kg), cocaine (60 mg/kg) and pyrazole (300 mg/kg) on the hepatic histology and monooxygenases in DBA/2 and C57Bl/6 strains of mice were investigated. CCL4 drug cocaine 8277979 In DBA/2 strain, coumarin 7 hydroxylase (COH) activity was increased from 3 to 5 fold by pyrazole, cocaine, HCBD and CCl4. CCL4 drug alcohol 8286481 FL can be induced by either acute or chronic administration of ethanol (EtOH), and/or several haloalkanes (carbon tetrachloride, CCl4; 1.2 dichloroethane, DCE; 1.1.2.2 tetrachloroethane, TTCE), both in laboratory animals and in man. CCL4 drug alcohol 1446373 The plasma AGP concentration in carbon tetrachloride (CCl4), allyl alcohol, bromobenzene, acetaminophen or N nitrosodimethylamine induced liver injury was increased to 2 3.5 times the normal level at 24 h after the intoxication. CCL4 addiction intoxication 1446373 The plasma AGP concentration in carbon tetrachloride (CCl4), allyl alcohol, bromobenzene, acetaminophen or N nitrosodimethylamine induced liver injury was increased to 2 3.5 times the normal level at 24 h after the intoxication. CCL4 addiction withdrawal 2136321 In the EtOH drinking group previously treated with CCl4 we found that irrespective of the time of EtOH withdrawal, EtOH elimination did not differ from that in the respective CCl4 treated group, only 12 hours after its withdrawal EtOH elimination was decreased in livers injured with CCl4 in dose of 5 mmoles/kg. CCL4 drug alcohol 2137379 The derangement to the Ca2(+) ATPase seems to be independent on a 'solvent effect' of the agent since the in vitro addition of increasing concentrations of either CCl4 or ethanol to control plasma membranes does not affect the enzymatic activity. CCL4 addiction intoxication 2137379 The same procedure is however able to affort a significant protection against the exacerbation of the damage to the Ca2(+) ATPase becoming evident late during the course of CCl4 intoxication. CCL4 drug alcohol 2739484 6 pigs (19.75 27.0 kg) were intoxicated with different dosages of CCl4 and ethanol. CCL4 drug alcohol 2739484 Three different regimens of CCl4 and C2H5OH applications were used: CCl4 was administered intragastrically alone (group 1) or combined with ethanol (group 2), and CCl4 was given intragastrically and ethanol intravenously (group 3). CCL4 addiction intoxication 2739484 CCl4 and C2H5OH intoxication in pigs causes effects that are different from those described in humans or laboratory rats. CCL4 addiction intoxication 2684438 Of course both phenomena produce cell damage as in the case of CCl4 or BrCCl3 intoxication. CCL4 drug alcohol 2574105 Beta hexosaminidase activity in alcoholic fatty liver and in CCl4 induced liver fibrosis of the rat. CCL4 drug alcohol 2574105 beta Hexosaminidase (Hex) activity was previously found to be increased in the sera of patients with liver cirrhosis, cholestasis and acute alcohol intoxication, as well as in rats with CCl4 induced liver cirrhosis. CCL4 addiction intoxication 2574105 beta Hexosaminidase (Hex) activity was previously found to be increased in the sera of patients with liver cirrhosis, cholestasis and acute alcohol intoxication, as well as in rats with CCl4 induced liver cirrhosis. CCL4 drug alcohol 2574105 We studied this enzymatic activity in the sera and liver tissue of rats with alcoholic fatty liver due to prolonged alcohol intake and CCl4 induced liver fibrosis in association with moderate alterations in liver function tests. CCL4 drug alcohol 3583469 Both CCl4 and ethanol produce a liver damage by free radical mechanisms causing a lesion of liver cell endoplasmic reticulum. CCL4 drug alcohol 3583469 Protective effects of antioxidants on CCl4 or ethanol induced liver damage were investigated on this basis in adult Wistar rats. CCL4 addiction intoxication 3583469 In conclusion CCl4 intoxication is a suitable model for studying radical initiated liver injuries. CCL4 drug alcohol 3792537 Some methionine derivatives with the amine group acylated with an aliphatic group bearing a free, esterified or etherified thiol group in the omega position were prepared and tested for protection against CCl4, paracetamol, ethyl alcohol and ethionine intoxication. CCL4 addiction intoxication 3792537 Some methionine derivatives with the amine group acylated with an aliphatic group bearing a free, esterified or etherified thiol group in the omega position were prepared and tested for protection against CCl4, paracetamol, ethyl alcohol and ethionine intoxication. CCL4 addiction intoxication 4080564 The activities of an endogenous inhibitor and of a stimulator of cell proliferation were assayed in the livers of sham operated (SO) or partially hepatectomized (PH) adult rats; rats fed a choline supplemented (CS) or a choline devoid (CD) diet; the same diets followed by acute CCl4 intoxication; the same diets supplemented with phenobarbital (PHB); or a CD diet containing DL ethionine (ETH). CCL4 addiction intoxication 4080564 Following PH, a CD diet, or CCl4 intoxication the inhibitor activity was suppressed, and there was a simultaneous appearance of a stimulator activity. CCL4 addiction intoxication 4080564 Thus, PH, a CD diet, and CCl4 intoxication cause similar cellular (loss and regeneration) and humoral homeostatic changes in adult rat livers. CCL4 drug alcohol 6532381 To study the effect of an acute dose of ethanol on carbon tetrachloride (CCl4) concentration and hepatotoxicity, female rats received ethanol (2.5 ml/kg body wt.) CCL4 drug alcohol 6532381 Three hours after acute CCl4 intoxication there was a striking increase in CCl4 concentration in animals treated simultaneously with ethanol intragastrically compared to those receiving ethanol intraperitoneally. CCL4 addiction intoxication 6532381 Three hours after acute CCl4 intoxication there was a striking increase in CCl4 concentration in animals treated simultaneously with ethanol intragastrically compared to those receiving ethanol intraperitoneally. CCL4 drug alcohol 6532381 Serum activities of glutamate oxalacetate transaminase, glutamate pyruvate transaminase and glutamate dehydrogenase were found to be considerably higher in animals treated with the combination of CCl4 and ethanol when compared to those receiving CCl4 alone, showing that ethanol given intraperitoneally or intragastrically enhances CCl4 hepatotoxicity. CCL4 drug alcohol 6532381 Since the intraperitoneal administration of ethanol led to a reduction rather than an increase in CCl4 concentration in the early phase of intoxication, additional mechanisms independent of actual levels of CCl4, such as direct effects of ethanol on the CCl4 metabolizing enzyme of the membrane of the endoplasmic reticulum, have to be implicated in the pathogenesis of the potentiation of CCl4 hepatotoxicity by ethanol.

CCL4 drug alcohol 6882388 Second derivative spectroscopy was used to determine the conjugated diene shift that measures the extent of the first step of lipid peroxidation after carbon tetrachloride (CCl4), bromotrichloromethane (BrCCl3) and ethanol intoxication. CCL4 addiction intoxication 6882388 Second derivative spectroscopy was used to determine the conjugated diene shift that measures the extent of the first step of lipid peroxidation after carbon tetrachloride (CCl4), bromotrichloromethane (BrCCl3) and ethanol intoxication. CCL4 drug alcohol 6877050 To study the effect of an acute dose of alcohol on the hepatotoxicity due to CCl4, rats received alcohol (4 g/kg BW) and/or CCl4 (1.5 ml/kg BW) by concomitant intragastric intubation. CCL4 drug alcohol 6877050 Compared to animals receiving CCl4 alone, the simultaneous application of CCl4 and alcohol resulted 12 h after administration in significantly lower serum activities of glutamate oxalacetate transaminase (1005 +/ 70 vs 739 +/ 47; p less than 0.01) and glutamate pyruvate transaminase (746 +/ 10 vs 330 +/ 41; p less than 0.01), whereas 36 h after administration, an increase of serum enzyme activities was observed. CCL4 drug alcohol 6877050 By histological assessment, liver damage was also much less pronounced 12 h after combined administration of CCl4 and ethanol, compared to CCl4 alone, whereas the reversed constellation could be demonstrated 36 h after administration. CCL4 drug alcohol 6877050 These results therefore show that in the early phase of CCl4 intoxication an acute dose of alcohol may partially protect from CCl4 hepatotoxicity, whereas potentiation was observed under these experimental conditions in the late phase of CCl4 intoxication. CCL4 addiction intoxication 6877050 These results therefore show that in the early phase of CCl4 intoxication an acute dose of alcohol may partially protect from CCl4 hepatotoxicity, whereas potentiation was observed under these experimental conditions in the late phase of CCl4 intoxication. CCL4 addiction intoxication 6178134 The occurrence of AFP was studied in normal and diseased livers of mice and rats: (a) fetal and neonatal livers; (b) liver regeneration after CCl4 intoxication; (c) chemical hepatocarcinogenesis. CCL4 addiction intoxication 6178134 After CCl4 intoxication of low and high AFP producing mouse strains, cellular AFP is found in hepatocytes of portal, periportal and intermediate zones.

CDK5 drug amphetamine 29225566 Cdk5 Is Essential for Amphetamine to Increase Dendritic Spine Density in Hippocampal Pyramidal Neurons. CDK5 addiction addiction 29225566 Recent reports suggest that Cdk5 plays an important role in drug addiction, but its role in psychostimulant's effects on dendritic spines in hippocampus remain unknown. CDK5 drug amphetamine 29225566 Primary cultures and organotypic slice cultures were used for cellular, molecular, pharmacological and biochemical analyses of the role of Cdk5/p25 in amphetamine induced dendritic spine formation. CDK5 drug amphetamine 29225566 Either genetic or pharmacological inhibition of Cdk5 activity prevented the amphetamine induced increase in dendritic spine density. CDK5 drug amphetamine 29225566 Amphetamine also increased spine density in neurons overexpressing the strong Cdk5 activator p25. CDK5 drug amphetamine 29225566 Moreover, we show that the Cdk5/p25 signaling and calpain activity are both necessary for the effect of amphetamine on dendritic spine density.

CDK5 drug cannabinoid 29082320 THC injection in mice with a history of repeated THC treatment increased expression of cyclin dependent kinase 5 (Cdk5) and its regulatory protein p35 only in the PFC. CDK5 drug cannabinoid 29082320 This increase in Cdk5 and p35 expression in PFC was also found in mice that had only received repeated THC administration, suggesting that this effect might be due to induction of ΔFosB. CDK5 drug cannabinoid 29082320 Phosphorylation of glycogen synthase kinase 3β (GSK3β), a Cdk5 target, was reduced in PFC after repeated THC treatment regardless of THC history, and phosphorylation of dopamine and cAMP regulated phosphoprotein of 32 kDa (DARPP 32) at the Cdk5 regulated threonine 75 site was unchanged.

CDK5 addiction reward 27122028 We sought to examine the role of histone modifications at the murine Cdk5 (cyclin dependent kinase 5) locus, given growing evidence of Cdk5 expression in nucleus accumbens (NAc) influencing reward related behaviors. CDK5 drug cocaine 27122028 We examined the behavioral consequences of this epigenetic remodeling and found that Cdk5 targeted H3K9/14ac increased cocaine induced locomotor behavior, as well as resilience to social stress. CDK5 drug cocaine 27122028 Conversely, Cdk5 targeted H3K9me2 attenuated both cocaine induced locomotor behavior and conditioned place preference, but had no effect on stress induced social avoidance behavior. CDK5 addiction reward 27122028 The current study provides evidence for the causal role of Cdk5 epigenetic remodeling in NAc in Cdk5 gene expression and in the control of reward and stress responses. CDK5 drug cocaine 27122028 In particular, epigenetic regulation of the Cdk5 gene alters responses to cocaine and stress in mouse and rat models.

CDK5 drug alcohol 26617831 Cdk5 kinase activity and cell survival rate in primary hippocampal neuron cultures treated with ethanol or ethanol and polydatin were measured in the in vitro study. CDK5 drug alcohol 26617831 Polydatin reversed the performance impairments in chronic ethanol treated rats in Morris water maze test, and decreased unregulated Cdk5 expression. CDK5 drug alcohol 26617831 Moreover, polydatin increased cell survival rate, and decreased Cdk5 activity in the ethanol treated primary culture of hippocampal neurons. CDK5 drug alcohol 26617831 The study results suggest that polydatin exhibits neuroprotective potential for ethanol induced neurotoxicity, both in vivo and in vitro, which is most likely related to its ability to target Cdk5 in neurons. CDK5 drug cocaine 26377474 We also found that H4R3me2a is upregulated in NAc after repeated cocaine administration, and that H4R3me2a upregulation in turn controls the expression of Cdk5 and CaMKII.

CDK5 drug amphetamine 24939858 Similarly, transient viral expression in the NAcc exclusively during amphetamine exposure of a threonine alanine mutant form of Kal7 [mKal7(T1590A)] that is not phosphorylated by Cdk5 also prevented the accrual of contextual conditioning and spared the induction of sensitization.

ECT addiction addiction 25561962 the current available evidence does not support using ECT for the treatment of addictive disorders, and hence is unethical, unacceptable and inhumane and warrants immediate social and political attention. ECT drug benzodiazepine 25553236 After seven years a lorazepam provocation test was performed as he had a new relapse after 3 weeks without ECT. ECT addiction relapse 25553236 After seven years a lorazepam provocation test was performed as he had a new relapse after 3 weeks without ECT. ECT drug benzodiazepine 24901428 It initially responded to a lorazepam challenge; however, a complicated hospital course and deterioration of the patient's condition, including septic shock, delirium, and continued catatonic symptoms, led to the pursuit of ECT to treat her symptoms. ECT drug benzodiazepine 24459371 Majority of patients responded to therapy either by lorazepam alone or to its augmentation with modified ECT. ECT drug benzodiazepine 24416611 Some improvement was achieved through supportive therapy, high dose of lorazepam, and a series of 10 ECT sessions. ECT drug alcohol 23859979 However, similar to most antidepressant trials, patients with depression and comorbid alcohol and substance abuse are excluded from ECT efficacy studies. ECT drug alcohol 23859979 Through a retrospective chart review, we compared response to ECT in patients with mood disorder and comorbid alcohol and drug abuse to those with mood disorder only. ECT drug alcohol 23859979 There was no difference in ECT outcome between those with comorbid alcohol abuse and those without based on percent decrease in pre and post ECT symptom scores (abuse: mean [SD], 0.89 [0.2] vs nonabuse: mean [SD], 0.93 [0.16]; Wilcoxon, 1332; P = 0.086). ECT drug alcohol 23859979 Our results indicate that comorbid alcohol and drug abuse may influence the response to ECT in the treatment of mood disorders.

ECT drug benzodiazepine 20851717 Midazolam administration into the Ect, Per, and Ent reduced freezing responses. ECT drug benzodiazepine 20159196 The interest of this report is (1) it reinforces the need to be cautious before prescribing neuroleptics in adolescents presenting with symptoms of catatonia; (2) the complete recovery from catatonia after treatment with intensive care and more than three weeks of intravenous clonazepam without the use of ECT and (3) the effectiveness of carbamazepine over a long period of follow up. ECT addiction withdrawal 19686432 Based on the patient's bipolar disorder, the mechanism of action of ECT and the observation of ECT effectiveness on her PGAD, we hypothesize the following: (i) bipolar disorder led to central hyperactive dopamine release, an important component in the pathophysiology of her PGAD; (ii) central serotonin deficiency after selective serotonin reuptake inhibitor (SSRI) withdrawal resulted in a lack of inhibition of sexual excitement; (iii) ECT resulted in lowering of the hyperstimulated central dopamine release; and (iv) ECT led to an increase in sexual inhibition by stimulating serotonin activity. ECT drug benzodiazepine 12506260 If necessary, the patient could receive 3 mg/day with a 6 day full dose treatment and then, treatment would progressively be reduced; 4) If the patient failed to respond to lorazepam, ECT are needed; 5) Earlier use of ECT is recommended if autonomic instability or hyperthermia appears and malignant catatonia is suspected. ECT drug benzodiazepine 9661088 The use of flumazenil in the anxious and benzodiazepine dependent ECT patient. ECT drug benzodiazepine 9661088 Many patients who receive electroconvulsive therapy (ECT) are benzodiazepine dependent or are anxious and require benzodiazepine drugs. ECT drug benzodiazepine 9661088 Because these agents may diminish the therapeutic effectiveness of ECT, we explored the dosing, safety, and efficacy of pre ECT flumazenil administration, a benzodiazepine competitive antagonist, in patients receiving benzodiazepine medications. ECT drug benzodiazepine 9661088 We report our experience with 35 patients who received both flumazenil and benzodiazepine drugs during their ECT course. ECT drug benzodiazepine 9661088 Flumazenil offers the promise of safe and effective ECT in patients receiving benzodiazepine drugs. ECT drug benzodiazepine 9661088 In addition, the direct effect of benzodiazepine drugs and the flumazenil/benzodiazepine combination on ECT seizures remains to be determined.

TANK drug nicotine 31941548 In an online experiment, participants were randomly assigned to view one of four videos, which included smoking, vaping (cigalike or tank system), or neutral cues. TANK addiction relapse 31888637 Compared with modular devices (18.9% relapse), tank models (45.6%; adjOR = 3.63; 95% CI, 1.33 9.95) were associated with increased relapse; evidence was unclear for disposable/cartridge refillable devices (41.9%; adjOR = 2.83; 95% CI, 0.90 8.95). TANK drug nicotine 31837232 Compared to cigarette smoking, nicotine exposure for variable power tank users was similar, while cig a like (t(30) = 2.71, P = 0.011, d = 0.745) and fixed power tank users (t(30) = 3.37, P = 0.002, d = 0.993) were exposed to less nicotine. TANK drug nicotine 31837232 During a 24 hour period in a hospital setting in the United States, nicotine exposure for dual users of e cigarettes and cigarettes was similar when using cigarettes or variable power tank devices only but was lower for those using cig a like or fixed power devices only. TANK drug nicotine 31538804 Electronic nicotine delivery systems (ENDS) are devices that contain a power source, a heating element, and a tank or cartridge containing an "e liquid," which is a mixture of nicotine and flavoring in a glycerol propylene glycol vehicle. TANK drug alcohol 30946939 Animals were exposed to ethanol (1% v/v, 20 min) or control water, followed by treatment with NAC (1 mg/L, 10 min) or control water daily for 8 days; 24 h later, experimental animals were submitted to the novel tank test (NTT). TANK drug alcohol 30721969 The Cortical Neuroimmune Regulator TANK Affects Emotional Processing and Enhances Alcohol Drinking: A Translational Study. TANK drug alcohol 30721969 In this report, we analyse how the gene "TRAF family member associated NF κB activator" (TANK) affects alcohol drinking behavior. TANK drug alcohol 30721969 Based on our recent discovery in a large GWAS dataset that suggested an association of TANK, SNP rs197273, with alcohol drinking, we report that SNP rs197273 in TANK is associated both with gene expression (P = 1.16 × 10 19) and regional methylation (P = 5.90 × 10 25). TANK drug alcohol 30721969 A tank knock out mouse model suggests a role of TANK in alcohol drinking, anxiety related behavior, as well as alcohol exposure induced activation of insular cortex NF κB. TANK addiction aversion 30721969 Functional and structural neuroimaging studies among up to 1896 adolescents reveal that TANK is involved in the control of brain activity in areas of aversive interoceptive processing, including the insular cortex, but not in areas related to reinforcement, reward processing or impulsiveness.

TANK drug alcohol 30721969 Our findings suggest that the cortical neuroimmune regulator TANK is associated with enhanced aversive emotional processing that better protects from the establishment of alcohol drinking behavior. TANK addiction aversion 30721969 Our findings suggest that the cortical neuroimmune regulator TANK is associated with enhanced aversive emotional processing that better protects from the establishment of alcohol drinking behavior. TANK drug nicotine 29481898 Here we evaluated the rewarding effects of nicotine and caffeine using a tank with five arms distributed radially from a central chamber that we have denoted Fish Tank Radial Maze (FTRM). TANK drug nicotine 29129555 To address this issue, we monitored blood nicotine levels during the acute phase in volunteers using disposable cigalikes (CLs) and a tank model (TM) and compared them with blood nicotine levels in subjects using a tobacco cigarette (TC). TANK drug psychedelics 28855876 In this study, MDMA (2.5 10 mg/kg), DOB (0.5 mg/kg), or PMA (0.005, 0.1, or 0.25 mg/kg) were administered intramuscularly to adult zebra fish, alone or in combination with the V1a vasopressin antagonist, SR49059 (0.01 1 ng/kg), before carrying out conditioned place preference (CPP), social preference, novel tank diving, and light dark tests in order to evaluate subsequent rewarding, social, and emotional like behavior. TANK addiction reward 28855876 In this study, MDMA (2.5 10 mg/kg), DOB (0.5 mg/kg), or PMA (0.005, 0.1, or 0.25 mg/kg) were administered intramuscularly to adult zebra fish, alone or in combination with the V1a vasopressin antagonist, SR49059 (0.01 1 ng/kg), before carrying out conditioned place preference (CPP), social preference, novel tank diving, and light dark tests in order to evaluate subsequent rewarding, social, and emotional like behavior. TANK addiction reward 28855876 The combination of SR49059 and each drug progressively blocked: (1) rewarding behavior as measured by CPP in terms of time spent in drug paired compartment; (2) prosocial effects measured on the basis of the time spent in the proximity of a nacre fish picture; and (3) anxiolytic effects in terms of the time spent in the upper half of the novel tank and in the white compartment of the tank used for the light dark test. TANK drug alcohol 28797598 In this study, ethanol induced change in time spent by zebrafish on the initially non preferred tank side was studied by conditioning adult zebrafish to ethanol dissolved in water (0.00% 1.00%; 1.25%; 1.50%; 1.60%; 1.75% vol/vol) paired with an initially non preferred environment. TANK drug alcohol 28714785 Zebrafish were initially exposed to different alcohol treatments and submitted to an inhibitory avoidance protocol, where an electroshock was applied to the fish as they swam from the white to the black side of a shuttle box tank (naturally preferred environment of zebrafish). TANK drug alcohol 28714785 Animals from the control and 0.5% acute alcohol groups exhibited high latency to enter the black side of the tank after the first exposure to electroshock, in addition to higher freezing and a shorter distance from the bottom of the tank, suggesting acute alcohol exposure did not affect aversive learning in zebrafish. TANK addiction aversion 28714785 Animals from the control and 0.5% acute alcohol groups exhibited high latency to enter the black side of the tank after the first exposure to electroshock, in addition to higher freezing and a shorter distance from the bottom of the tank, suggesting acute alcohol exposure did not affect aversive learning in zebrafish. TANK drug benzodiazepine 28645783 Adult zebrafish were treated with M. angolensis extract, fluoxetine, desipramine, and diazepam followed by testing in the novel tank and light dark tests. TANK drug nicotine 28393086 Among the 8 tank users, number of puffs was positively correlated with amount of nicotine inhaled, Cmax, and area under the plasma nicotine concentration time curve (AUC0→90min) while interpuff interval was negatively correlated with Cmax and AUC0→90. TANK drug alcohol 28092494 In the current study, we analyzed the time course of alcohol induced behavioral changes of zebrafish while being immersed in alcohol solution in a 1.5 L tank. TANK drug benzodiazepine 27061599 Successively, they explored the relationship between the internal concentrations of oxazepam and the effects on fish exploratory behavior quantified by performing 2 types of behavioral tests, the novel tank diving test and the shelter seeking test. TANK addiction relapse 27061599 Successively, they explored the relationship between the internal concentrations of oxazepam and the effects on fish exploratory behavior quantified by performing 2 types of behavioral tests, the novel tank diving test and the shelter seeking test. TANK drug alcohol 26781213 We utilized the zebrafish model system to address the effect of chronic alcohol exposure (0.5% alcohol in the holding tank for 9 weeks) on reproductive capacity. TANK drug alcohol 26781213 In agreement with observations on fecundity, the chronic alcohol exposure leads to increased anxiety, as measured by the novel tank diving assay. TANK drug amphetamine 26433144 In the novel tank test, acute administration of METH (2 mg/L) induced a significant decrease in the number of total vertical transitions and time spent in the upper zone. TANK drug nicotine 25643654 We also found that chronic exposure to nicotine evokes robust anxiogenic behavioral responses in zebrafish tested in the novel tank test paradigm. TANK addiction aversion 25599606 Habituation to a repeated environmental stimulus and overall sensorimotor function were assessed using a tap startle test; measurements of anxiety and exploration behavior were made following introduction to a novel tank; and spatial discrimination learning was assessed using aversive control in a three chambered apparatus. TANK drug alcohol 25599606 Ethanol treated fish were more active both at baseline and following a tap stimulus compared to the control fish and were hyperactive when placed in a novel tank. TANK drug nicotine 26946554 Aims of the study were to (1) measure and compare nicotine concentration in e liquids to values reported by manufacturers on packaging labels; (2) assess the precision of nicotine delivery from tank during aerosol formation. TANK drug alcohol 24922137 In this case study, we examined how SABMiller engaged the think tank Demos to produce reports on binge drinking, which were heavily promoted among policymakers at crucial stages in the development of the UK government's 2012 alcohol strategy. TANK addiction intoxication 24922137 In this case study, we examined how SABMiller engaged the think tank Demos to produce reports on binge drinking, which were heavily promoted among policymakers at crucial stages in the development of the UK government's 2012 alcohol strategy. TANK drug nicotine 24922137 In this instance, the perceived independence of an influential think tank was used to promote industry interests in tactics similar to those of transnational tobacco corporations. TANK drug alcohol 24681197 For the drug seeking behavior, we used a place preference paradigm (shuttle box tank) before and after alcohol exposure in acute (single exposure) and chronic (7 days) treatments. TANK addiction relapse 24681197 For the drug seeking behavior, we used a place preference paradigm (shuttle box tank) before and after alcohol exposure in acute (single exposure) and chronic (7 days) treatments. TANK drug cannabinoid 24216135 Here, we explore the effects of acute 20 min exposure to two commonly abused psychotropic compounds, Δ(9) tetrahydrocannabinol (THC) and heroin, on adult zebrafish behavior in the novel tank test. TANK drug opioid 24216135 Here, we explore the effects of acute 20 min exposure to two commonly abused psychotropic compounds, Δ(9) tetrahydrocannabinol (THC) and heroin, on adult zebrafish behavior in the novel tank test. TANK drug nicotine 23869690 Here, we tested adult zebrafish from the casper line, as well as wild type (Tübingen, TU) and wild types treated as embryos with PTU on three commonly used behavioural endpoints in neuroscience: novel tank test (similar to open field in rodents), conditioned place preference for nicotine, and social cohesion (using a new method of cluster analysis). TANK drug alcohol 23658154 The novel gene tank, a tumor suppressor homolog, regulates ethanol sensitivity in Drosophila. TANK drug alcohol 23658154 Based on a previous genetic screen in Drosophila for ethanol sedation mutants, we identified a novel gene, tank (CG15626), the homolog of the mammalian tumor suppressor EI24/PIG8, which has a strong role in regulating ethanol sedation sensitivity. TANK drug alcohol 23658154 Genetic and behavioral analyses revealed that tank acts in the adult nervous system to promote ethanol sensitivity. TANK drug alcohol 23658154 We localized the function of tank in regulating ethanol sensitivity to neurons within the pars intercerebralis that have not been implicated previously in ethanol responses. TANK drug alcohol 23658154 We show that acutely manipulating the activity of all tank expressing neurons, or of pars intercerebralis neurons in particular, alters ethanol sensitivity in a sexually dimorphic manner, since neuronal activation enhanced ethanol sedation in males, but not females. TANK drug alcohol 23658154 Finally, we provide anatomical evidence that tank expressing neurons form likely synaptic connections with neurons expressing the neural sex determination factor fruitless (fru), which have been implicated recently in the regulation of ethanol sensitivity. TANK drug alcohol 23558086 We assessed the effects of withdrawal from chronic ethanol exposure, and subsequent administration of fluoxetine (Prozac®), buspirone (Buspar®), and diazepam (Valium) using two behavioral paradigms; the Novel Tank Diving Test and the Light/Dark Choice Assay.

TANK drug alcohol 22266470 Animated bird silhouette above the tank: acute alcohol diminishes fear responses in zebrafish. TANK drug alcohol 22266470 The fear inducing stimulus was found to decrease the distance of the zebrafish from the bottom of the tank, to increase number of erratic movements, and to increase the number of jumps in alcohol exposed fish (versus control fish). TANK drug opioid 22205946 Using the novel tank diving tests, we first showed that morphine withdrawn zebrafish display anxiety related swimming behaviors such as decreased exploratory behavior and increased erratic movement. TANK drug alcohol 21255611 In this study, we assess the effects of both acute and chronic ethanol exposure on anxiety like behaviors in zebrafish, using two behavioral paradigms, the Novel Tank Diving Test and the Light/Dark Choice Assay. TANK drug alcohol 20974186 The largest increase in preference is in response to a 1.5% ethanol administered in the tank water. TANK drug alcohol 9392779 In Experiment 2, either 4.5 or 5.25 g/kg/day of ethanol was administered on PD 7 9 and place learning was tested in a 171 cm diameter tank.

PENK drug opioid 18184800 Heroin abuse was significantly associated with PENK polymorphic 3' UTR dinucleotide (CA) repeats; 79% of subjects homozygous for the 79 bp allele were heroin abusers. PENK drug opioid 18184800 Control Met/Met individuals expressed lower PENK mRNA than Val carriers, a pattern reversed in heroin users. PENK drug opioid 18184800 Up regulation of NAc PENK in Met/Met heroin abusers was accompanied by impaired tyrosine hydroxylase (TH) mRNA expression in mesolimbic dopamine neurons. PENK drug opioid 18184800 In contrast to PENK, no association was detected between PDYN genotype (68 bp repeat element containing one to four copies of AP 1 binding sites in the promoter region) and heroin abuse, although there was a clear functional association with striatal PDYN mRNA expression: an increased number of inducible repeats (three and four) correlated with higher PDYN levels than adult or fetal subjects with noninducible (one and two) alleles.

PENK drug cannabinoid 9734704 Perinatal delta9 tetrahydrocannabinol exposure reduces proenkephalin gene expression in the caudate putamen of adult female rats. PENK drug cannabinoid 9734704 The results showed a marked reduction in proenkephalin mRNA levels in the caudate putamen of delta9 THC exposed females as compared to oil exposed females, whereas no changes were observed between delta9 THC and oil exposed males. PENK drug cannabinoid 9734704 There were no differences in proenkephalin mRNA levels in the nucleus accumbens, central amygdala and prefrontal cingulate cortex between males and females perinatally exposed to delta9 THC and their respective controls, although a certain trend to decrease was observed in delta9 THC exposed females.

PENK drug alcohol 9630499 Enhanced sensitivity of the nucleus accumbens proenkephalin system to alcohol in rats selectively bred for alcohol preference. PENK drug opioid 9602109 In the present study, the mRNA expression of the dopamine receptors, D1 and D2, and the opioid peptides, prodynorphin and proenkephalin, were analyzed in the rat striatum using in situ hybridization histochemistry. PENK drug cocaine 9602109 Proenkephalin and the D2 receptor mRNAs were not altered during cocaine abstinence, though proenkephalin was elevated following acute but not repeated cocaine administration. PENK drug alcohol 9581644 Gel retardation assays with oligomers encoding the rat proenkephalin CRE 1 and CRE 2 were performed to determine the effects of ethanol on CRE binding activity. PENK drug alcohol 9464643 An in situ hybridization study showed an increase in the prodynorphin mRNA level at 24 and 48 h (by 189 and 146%, respectively) after ethanol withdrawal, whereas the proenkephalin mRNA level remained unchanged.

PENK drug opioid 9227847 Effect of morphine on proenkephalin gene expression in the rat brain. PENK drug opioid 9227847 Therefore, in situ hybridization with probes directed against intronic sequences to measure the primary transcript of proenkephalin (PPE) mRNA (heteronucleic RNA, hnRNA) in the rat brain following morphine administration was used in this study. PENK drug opioid 9157322 Using in situ hybridization histochemistry, the messenger RNA expression of the opioid precursors, prodynorphin and proenkephalin, was studied in whole hemisphere human brain tissue. PENK drug opioid 9157322 The marked anatomical dissociation between the expression of these two opioid peptide genes, seen clearly in whole hemisphere sections, indicates that distinct functions must be subserved by the prodynorphin and proenkephalin systems in the human brain. PENK drug cocaine 8998398 Adaptive changes in the proenkephalin and D2 dopamine receptor mRNA expression after chronic cocaine in the nucleus accumbens and striatum of the rat. PENK drug cocaine 8998398 The effects of single and repeated cocaine administration on proenkephalin (PENK) and D2 dopamine receptor mRNA expression in the nucleus accumbens and striatum of the rat were studied. PENK drug cocaine 8998398 The effects of single and repeated cocaine administration on proenkephalin (PENK) and D2 dopamine receptor mRNA expression in the nucleus accumbens and striatum of the rat were studied. PENK drug cocaine 8998398 Acute cocaine administration increased PENK expression of mRNA in the striatum and decreased it in both those structures after 24 and 48 h. D2 receptor expression of mRNA fell after 3 h, returned to the control value after 24 h and rose after 48 h in both those brain regions following single cocaine injection. PENK drug cocaine 8998398 Repeated cocaine increased PENK expression of mRNA after 3 h, but after 24 and 48 h depletion of mRNA expression was observed. PENK drug cocaine 8998398 The obtained results suggest that in the nucleus accumbens and striatum there is an opposite regulation between PENK and D2 receptor gene expression a short time after single and chronic cocaine administration. PENK drug cocaine 8998398 Hence, these data provide further evidence for the significance of the PENK and dopamine systems in the neurochemical mechanism of cocaine.

IFNG addiction withdrawal 27622168 Effect of Moderate Exercise on Serum Interferon Gamma and Interleukin 17 Levels in the Morphine Withdrawal Period. IFNG drug opioid 27622168 This study aimed to investigate the changes in serum levels of interferon gamma (IFN γ) and interleukin 17 (IL 17) during the morphine withdrawal syndrome induced by 8 weeks of moderate exercise and their effects on the immune system function. IFNG addiction withdrawal 27622168 This study aimed to investigate the changes in serum levels of interferon gamma (IFN γ) and interleukin 17 (IL 17) during the morphine withdrawal syndrome induced by 8 weeks of moderate exercise and their effects on the immune system function. IFNG drug cocaine 18719314 Cocaine self administered for 18 days induced a significant increase in spleen weight, plasma corticosterone levels, interleukin (IL) 10, and tumor necrosis factor alpha production, while concanavalin A stimulated proliferation responses of peripheral blood T lymphocytes and interferon gamma production by splenic lymphocytes were not altered. IFNG drug opioid 18040852 The splenocytes from protected mice and morphine low concentration treated infected PM, elaborated significantly (p < 0.05) enhanced levels of interleukin 12, interferon gamma, tumor necrosis factor alpha, granulocyte macrophage colony stimulating factor and nitrite in the culture medium; a high dose/concentration suppressed their elaboration. IFNG drug opioid 17993452 This study was performed to investigate the in vitro production of interferon gamma and interleukin 10 after antigenic stimulation of cells using whole blood from opioid addicts. IFNG drug opioid 17993452 The results demonstrated a significant decrease in interferon gamma production and an increase in interleukin 10 secretion in heroin addicts, relative to the control group (35.9+/ 26.3 versus 110.2+/ 60.3 pg/mL, p<0.01 and 71.8+/ 28.4 versus 17.1+/ 13.5 pg/mL, p<0.01, respectively), however the changes in these values in opium addicts were not significant compared to healthy individuals. IFNG drug alcohol 16792568 Efficacy of AM pretreatment with interferon gamma (IFN gamma) on IL 23 expression before ethanol exposure and infection was evaluated. IFNG drug alcohol 16792568 Interferon gamma pretreatment strongly inhibits AM IL 23 production in both the presence and absence of alcohol. IFNG addiction intoxication 16792568 Interferon gamma priming antagonizes IL 23 and is, therefore, not likely to be a useful adjuvant therapy in restoring IL 23/IL 17 responses during infection and intoxication. IFNG drug nicotine 12907840 We provided a self administered questionnaire to evaluate sleep habits, smoking and medical disorders to 578 men without any toxic exposure (20 64 years old), and measured natural killer (NK) cell activity in 324 men and production of interferon gamma (IFN gamma) and interleukin 4 (IL 4) after stimulation with phytohemagglutinin in 254 men. IFNG drug alcohol 11505051 The ratio of IL 4 to interferon gamma production by phytohemagglutinin stimulated PBMCs (as an approach to Th2/Th1 balance) was significantly lower in alcoholics than in healthy controls, both in the atopic and in the nonatopic group. IFNG drug alcohol 11454939 The current work shows ethanol also suppresses cytokine induced iNOS expression and reduces interleukin 1beta and tumor necrosis factor alpha potency without affecting interferon gamma potency. IFNG drug alcohol 11454939 Furthermore, ethanol inhibition of the 526 base fragment activity, which lacks interferon gamma enhancement of lipopolysaccharide induced luciferase activity, confirmed that interferon gamma responsive elements do not participate in acute ethanol induced inhibition of rat iNOS gene transcription.

IFNG addiction aversion 9394782 This aversive conditioned stimulus induces a reduction in splenic natural killer cell activity, splenocyte proliferation in response to mitogens, and diminished levels of interferon gamma (IFN gamma) production by splenocytes. IFNG drug alcohol 9347083 Alterations in tumor necrosis factor alpha, interferon gamma, and interleukin 6 production by natural killer cell enriched peripheral blood mononuclear cells in chronic alcoholism: relationship with liver disease and ethanol intake. IFNG drug opioid 9296419 Results show that morphine's immunomodulatory effects on NK cell activity begin within 30 min, continue for at least 12 h, and return to control values by 24 h. In contrast, proliferation of splenic T and B cells and interferon gamma production are not altered within 30 min; maximal suppression occurs at 1 h, and recovery begins within 2 h. In all immune measures, therefore, maximal suppression is present at the 1 h time point, and recovery is complete within 24 h. Morphine induces antinociception 30 min to 2 h after drug administration; recovery is complete within 6 h. These results suggest the possibility that different mechanisms modulate morphine's immunologic and analgesic effects. IFNG drug opioid 8632330 A second experiment showed that s.c. doses of N methylnaltrexone that do not gain access to the CNS, as determined by the tail withdrawal assay, do not antagonize the suppressive effects of a single, s.c. injection of morphine on the mitogen stimulated proliferation of splenic and blood lymphocytes, splenic natural killer cell activity and the production of interferon gamma by stimulated splenocytes. IFNG addiction withdrawal 8632330 A second experiment showed that s.c. doses of N methylnaltrexone that do not gain access to the CNS, as determined by the tail withdrawal assay, do not antagonize the suppressive effects of a single, s.c. injection of morphine on the mitogen stimulated proliferation of splenic and blood lymphocytes, splenic natural killer cell activity and the production of interferon gamma by stimulated splenocytes. IFNG drug alcohol 1662988 In addition, although ethanol had no effect on TNF binding to resting macrophages and to macrophages infected with M. avium, ethanol significantly reduced the expression of TNF receptors on interferon gamma stimulated macrophages. IFNG drug opioid 3040807 Opioid mediated suppression of interferon gamma production by cultured peripheral blood mononuclear cells. IFNG drug opioid 3040807 We tested the hypothesis that morphine and the endogenous opioid beta endorphin (beta END), a pituitary peptide released in increased concentrations during stress, can suppress the production of the key macrophage activating lymphokine interferon gamma (IFN gamma) by cultured human peripheral blood mononuclear cells (PBMNC).

FEV addiction reward 17356080 There is controversy about whether therapy with inhaled corticosteroids (ICSs) modifies the natural history of COPD, characterized by an accelerated decline in FEV(1). FEV drug nicotine 17356080 We aimed to determine whether the regular use of ICSs vs placebo improves FEV(1) decline in COPD patients, and whether this relationship is modified by gender and smoking.

CRHR2 drug alcohol 29118713 After having had continuous access to ethanol (20% weight/volume) for 4 weeks, control and stressed mice had CRF type 1 (CRFR1) or type 2 (CRFR2) receptor antagonists infused into the BNST and then had access to ethanol for 24 h. In separate cohorts of control and stressed mice, we assessed mRNA levels of BNST CRF, CRFR1 and CRFR2. CRHR2 drug alcohol 29118713 The selective blockade of BNST CRFR1 with CP376,395 effectively reduced alcohol drinking in non stressed mice, whereas the selective CRFR2 antagonist astressin2B produced a dose dependent increase in ethanol consumption in both non stressed controls and stressed mice. CRHR2 drug alcohol 29118713 CRF CRFR1 signaling in the BNST seems to underlie ethanol intake in non stressed mice, whereas CRFR2 modulates alcohol consumption in both socially defeated and non stressed mice with a history of chronic intake.

CRHR2 addiction intoxication 26247973 Corticotropin Releasing Factor Binding Protein and CRF2 Receptors in the Ventral Tegmental Area: Modulation of Ethanol Binge Drinking in C57BL/6J Mice. CRHR2 drug alcohol 26247973 Most studies with corticotropin releasing factor (CRF) and ethanol (EtOH) consumption have focused on CRF type 1 (CRF1) receptors; less is known about other components of the CRF system, such as the CRF type 2 (CRF2) receptors and the CRF binding protein (CRFBP). CRHR2 addiction intoxication 26247973 Potential interactions between VTA CRFBP and CRF2 receptors on EtOH binge drinking were also assessed. CRHR2 addiction withdrawal 25672976 CRF2 Receptor Deficiency Eliminates the Long Lasting Vulnerability of Motivational States Induced by Opiate Withdrawal. CRHR2 drug opioid 25672976 In this study, we report that genetic inactivation of the stress responsive corticotropin releasing factor receptor 2 (CRF2 / ) completely eliminates the reemergence of increased nonrewarded nose pokes, reflecting up shifted motivational states, triggered by ethological environmental stressors long after cessation of morphine administration in mice. CRHR2 addiction withdrawal 25672976 Accordingly, CRF2 receptor deficiency completely abolishes the increase in biomarkers of synthesis of major brain motivational substrates, such as ventral tegmental area (VTA) dopamine (DA) and amygdala γ aminobutyric acid (GABA) systems, associated with the stress induced reemergence of up shifted motivational states long after opiate withdrawal. CRHR2 addiction withdrawal 25672976 Nevertheless, neither CRF2 receptor deficiency nor long term opiate withdrawal affects amygdala CRF or hypothalamus CRF expression, indicating preserved brain stress coping systems. CRHR2 addiction withdrawal 25672976 Moreover, CRF2 receptor deficiency does not influence the locomotor or the anxiety like effect of long term opiate withdrawal. CRHR2 addiction withdrawal 25672976 Thus, the present results reveal an essential and specific role for the CRF2 receptor in the stress induced reemergence of up shifted motivational states and related alterations in brain motivational systems long after opiate withdrawal.

CRHR2 addiction withdrawal 25205625 Anxiety like behaviors observed during amphetamine withdrawal are mediated by increased expression and activity of corticotropin releasing factor type 2 (CRF2) receptors in the dorsal raphe nucleus (dRN). CRHR2 addiction withdrawal 25205625 Anxiety like behavior of rats during withdrawal can be reversed by CRF2 receptor antagonism in the dRN, but the efficacy of global central CRF2 receptor antagonism is unknown. CRHR2 addiction withdrawal 25205625 Rats undergoing withdrawal showed increased anxiety like behavior, which was reduced by ventricular infusion of the CRF2 antagonist antisauvagine 30 (ASV 2 μg/2 μl). CRHR2 drug amphetamine 25205625 Overall, these results suggest that central CRF2 antagonism reduces anxiety states during amphetamine withdrawal, and that behavioral effects may be dependent upon the balance of CRF1 and CRF2 receptor activity in anxiety related regions.

CRHR2 drug cocaine 25073922 Repeated treatment with cocaine potentiates glutamatergic transmission in the rat basolateral amygdala/cortex pathway through a synergistic action of D1 like dopamine receptors and CRH type 2α receptors (CRF2 α receptors). CRHR2 addiction addiction 25073922 D1 /CRF2 α receptor heteromerization might account, at least in part, for the complex physiological interactions established between dopamine and CRH in normal and pathological conditions such as addiction, representing a new potential pharmacological target.

CRHR2 drug alcohol 19151899 We recently reported that the ethanol augmentation of GABAergic synaptic transmission in rat CeA involves CRF1 receptors, because both CRF and ethanol significantly enhanced the amplitude of evoked GABAergic inhibitory postsynaptic currents (IPSCs) in CeA neurons from wild type (WT) and CRF2 knockout (KO) mice, but not in neurons of CRF1 KO mice. CRHR2 drug alcohol 19151899 A CRF1 (but not CRF2) KO construct and the CRF1 selective nonpeptide antagonist NIH 3 (LWH 63) blocked the augmenting effect of both CRF and ethanol on evoked IPSCs.

LPA addiction sensitization 22337641 The LPA induced pain model described here mimics aspects of the neuropathic pain state, including the sensitization of VGCC, and may be useful for the early assessment of drug candidates to treat neuropathic pain. LPA drug opioid 21453194 The aim was to evaluate the frequency in serum lipid disturbances of hepatitis C virus (HCV) seronegative heroin addicts; the capacity of high density lipoprotein (HDL) C and apolipoprotein B (apoB)/apolipoprotein A I (apoA I) for predicting hypertriglyceridemia/low HDL C profile; correlation of HDL C with the apoB/apoA I and their correlation to plasma apo/lipoproteins. LPA drug opioid 21453194 ApoB/apoA I showed stronger correlation with the observed apo/lipoproteins than the HDL C. The logistic regression model showed that apoB/apoA I index (OR 89.1, 95% CI 1.3 5971.2) is more significant predictor in developing hypertriglyceridemia/low HDL profile than HDL C. Heroin addiction is associated with decreased plasma concentrations of HDL C, apoA I, apoB, and increased TGL concentrations. LPA addiction addiction 21453194 ApoB/apoA I showed stronger correlation with the observed apo/lipoproteins than the HDL C. The logistic regression model showed that apoB/apoA I index (OR 89.1, 95% CI 1.3 5971.2) is more significant predictor in developing hypertriglyceridemia/low HDL profile than HDL C. Heroin addiction is associated with decreased plasma concentrations of HDL C, apoA I, apoB, and increased TGL concentrations. LPA drug opioid 21453194 In heroin addicts, HDL C concentrations are significantly associated with the apoB/apoA I index, which correlates to all lipid fractions and is a stronger predictor of metabolic syndrome lipid profile in heroin addicts. LPA drug alcohol 21301951 LPA generated three psychiatric symptom profiles: Low , High Alcohol , and High Internalizing Symptoms profiles. LPA drug alcohol 17429021 We applied latent profile analysis (LPA) to determine meaningful subgroups of women based on interrelationships among factors that contextualize women's vulnerability to sexual assault, including prior victimization, alcohol consumption, relationship expectancies of the assailant, and assertive precautionary habits. LPA drug alcohol 16739925 Ethanol inhibited LCAT and LPL activities, and increased apoA containing LP in blood serum. LPA drug alcohol 12916168 The 14th day after alcohol abolition was characterized by tendency to normalization of these disturbances, but at the 30th day of soberness a recurrence growing the changes of apoA containing lipoproteins transformation was observed. LPA drug alcohol 12916168 In the patients under intoxication period and first 3 days after alcohol abolition a significant increase of quantity of all the apoA containing lipoprotein populations took place which was restored completely in remission. LPA addiction intoxication 12916168 In the patients under intoxication period and first 3 days after alcohol abolition a significant increase of quantity of all the apoA containing lipoprotein populations took place which was restored completely in remission. LPA addiction dependence 12695531 The inhibitory effect of FAP showed a strong hydrocarbon chain length dependence with C12 being optimum in the Xenopus laevis oocytes and in LPA(3) expressing RH7777 cells. LPA addiction sensitization 12486210 It is concluded that troglitazone doses known to achieve insulin sensitization did not enhance rat apoA I promoter activity sufficiently to result in an increased apoA I mRNA or protein expression in the intact rat. LPA drug alcohol 11981126 ApoE genotypes and concentrations of serum cholesterol, triglyceride, and Lps containing apoA I, A II, B, E, and C III were determined in 84 male alcohol abusers before and after 3 weeks of abstinence. LPA addiction withdrawal 11981126 After withdrawal, concentrations of serum apoA I, LpA I, LpA I/A II, apoC III, LpC III non B, apoE, and LpE non B significantly decreased, whereas those of triglycerides and apoB increased; levels of cholesterol, LpC III:B, and LpB:E were not affected. LPA addiction withdrawal 11981126 After withdrawal, concentrations of serum apoA I, LpA I, LpA I/A II, apoC III, LpC III non B, apoE, and LpE non B significantly decreased, whereas those of triglycerides and apoB increased; levels of cholesterol, LpC III:B, and LpB:E were not affected. LPA drug alcohol 8855152 Serum concentrations of apo A I, LpA I, LpA I:A II, apo C III, and LpC III significantly (P alcohol intake (mean +/ SE in low drinkers vs in alcoholics) 1.45 +/ 0.03 vs 1.78 +/ 0.05 g/L; 0.45 +/ 0.02 vs 0.56 +/ 0.02 g/L; 0.99 +/ 0.02 vs 1.22 +/ 0.04 g/L; 27.6 +/ 1.5 vs 39.7 +/ 1.7 mg/L; and 8.4 +/ 0.9 vs 24.7 +/ 1.7 mg/L, respectively whereas apo B and LpC III:B concentrations tended to decrease 1.20 +/ 0.04 vs 1.06 +/ 0.04 g/L and 19.3 +/ 1.2 vs 14.9 +/ 1.0 mg/L, respectively. LPA addiction withdrawal 8855152 After withdrawal, the concentrations of serum apo A I, apo C III, LpA I, LpA I:A II, and LpC III decreased significantly (P alcohol consumption remained positively correlated to apo A I, LpA I:A II, apo C III, and LpC III concentrations. LPA drug alcohol 3517775 STA, apoA lipoprotein, HDL cholesterol, total cholesterol and triglycerides were tested in 44 men dealt in 4 groups (subjects with normal or elevated STA, alcoholic or withdrawn). ADA drug alcohol 31989819 Native ethanol dehydrogenase ADH2 and acetaldehyde dehydrogenase ADA from Dickeya zeae were further overexpressed, which enhanced the capability to utilize ethanol for squalene synthesis and endowed the engineered strain with greater adaptability to high ethanol concentrations. ADA drug alcohol 30991909 The protections afforded by the ADA for individuals with substance use disorders are restricted by what appears to be the statute's moralizing on drug and alcohol use and those who use these substances. ADA drug alcohol 30697154 To investigate the involvement of NAc RNA editing in alcohol addiction, we generated NAc specific knockout mice of the double stranded RNA specific adenosine deaminase ADAR2 using AAV GFP/Cre and conducted a battery of behavioral tests including anxiety and depression like behaviors.

ADA drug nicotine 29176829 Using the Truth Tobacco Industry Documents Library and Congressional records, we examined the tobacco industry's involvement with the 1990 Americans with Disabilities Act (ADA). ADA drug nicotine 29176829 During legislative drafting of the ADA (1989 1990), the Tobacco Institute, the tobacco industry's lobbying and public relations arm at the time, worked with industry lawyers and civil rights groups to include smoking in the ADA's definition of "disability." ADA drug nicotine 29176829 Language that would have explicitly excluded smoking from ADA coverage was weakened or omitted. ADA drug nicotine 29176829 Tobacco Institute lawyers did not think the argument that smokers are "disabled" would convince the courts, so in the two years after the ADA was signed into law, the Tobacco Institute paid a lawyer to conduct media tours, seminars, and write articles to convince employers that hiring only non smokers would violate the ADA. ADA drug nicotine 29176829 Employers and policy makers need to be aware that tobacco use is not protected by the ADA and should not be misled by tobacco industry efforts to insinuate otherwise. ADA addiction withdrawal 29142516 A total of 54 CD patients, with follow up of more than 6 months after the withdrawal of ADA, were enrolled. ADA addiction relapse 29142516 After discontinuing ADA, 59.3% patients suffered a clinical relapse. ADA addiction relapse 29142516 Fifty nine percent of patients experienced a relapse after discontinuing the limited period of ADA treatment, and most of them occurred within 1 year following cessation. ADA addiction relapse 29142516 Though 60.4% of the relapse patients responded to ADA again. ADA drug alcohol 29122710 Adenosine deaminase activity and gene expression patterns are altered after chronic ethanol exposure in zebrafish brain. ADA drug alcohol 29122710 However, we verified a decrease of ADA activity in membrane fraction after 28days (44%) of ethanol exposure. ADA drug alcohol 29122710 Altogether, the purine catabolism promoted by ADA may be an important target of the chronic toxicity induced for ethanol. ADA drug alcohol 28449374 Genetic Variability in Adenosine Deaminase Like Contributes to Variation in Alcohol Preference in Mice. ADA drug alcohol 28449374 Moreover, we found that the adenosine deaminase inhibitor EHNA reduced the difference in alcohol preference between CSS 2 and C57BL/6J mice. ADA drug alcohol 27838211 The activity of XO and ADA increased, and their mRNA expression was enhanced in the alcohol dependence group, but there was no significant difference in the activity of RPPPK and GPRPPAT in the liver, small intestine, and muscle; furthermore, no significant difference in the activity of HGPRT and APRT was observed in the brain. ADA addiction dependence 27838211 The activity of XO and ADA increased, and their mRNA expression was enhanced in the alcohol dependence group, but there was no significant difference in the activity of RPPPK and GPRPPAT in the liver, small intestine, and muscle; furthermore, no significant difference in the activity of HGPRT and APRT was observed in the brain. ADA drug alcohol 27838211 These results indicate that chronic alcohol administration might enhance the catabolism of purine nucleotides in tissues by inducing gene expression of ADA and XO, leading to elevation of plasma uric acid levels. ADA drug alcohol 23797318 Quercetin treatment prevented the cadmium induced increase in NTPDase, 5 nucleotidase, and ADA activities in Cd/ethanol group when compared to saline/ethanol group. ADA drug cocaine 22749927 Following one week withdrawal, the effects of intra NAc microinjections of the adenosine kinase inhibitor (ABT 702), the adenosine deaminase inhibitor (deoxycoformycin; DCF), the specific A(1) receptor agonist (CPA) and the specific A(2A) receptor agonist (CGS 21680) were tested on the behavioral expression of cocaine sensitization.

ADA drug opioid 22019714 Compared with those in the saline group, the content of AMP and GTP of heroin group decreased significantly; the UA concentration in plasma, ADA and XO activities and the mRNA level of ADA and XO in brain tissues in heroin group increased significantly; the mRNA level of AK, APRT and HGPRT in brain tissues in heroin group decreased significantly (P<0.01). ADA addiction withdrawal 21951369 This review looks into the application of acute drug administration (ADA) against febrile and prolonged nonfebrile seizures in children, seizure clustering (habitual or at drug withdrawal), catamenial epilepsy, response to seizure "warnings", and prophylaxis of seizures at perceived increased risk (reflex epilepsies, long distance travel, lifestyle, and social occasions). ADA drug benzodiazepine 21951369 The drugs most commonly used for ADA are the benzodiazepines diazepam (oral or rectal), clobazam and buccal or nasal midazolam, and lorazepam. ADA drug nicotine 21456032 In all, 41% of CD patients required ADA DE, with shorter time to DE in smokers, men, and patients with isolated colonic disease. ADA drug opioid 22876215 The paper also draws parallels between methadone and other medical conditions and analyzes the problem in the context of disabilities encompassed in the ADA.

ADA drug opioid 16223513 When two heroin administration groups were compared with the control group, the concentrations of plasma uric acid and ADA in plasma, brain, liver, and small intestine increased, whereas the plasma urea nitrogen concentrations in two heroin administration groups and the plasma creatinine concentration in the 3 day heroin administration group did not increase. ADA drug opioid 16223513 When two withdrawal groups were compared with two heroin administration groups, the concentrations of plasma uric acid and ADA in liver and small intestine decreased, but there was no significant reduction in ADA concentrations of the brain, while the plasma ADA concentrations in the two withdrawal groups were significantly higher than those of two heroin administration groups. ADA addiction withdrawal 16223513 When two withdrawal groups were compared with two heroin administration groups, the concentrations of plasma uric acid and ADA in liver and small intestine decreased, but there was no significant reduction in ADA concentrations of the brain, while the plasma ADA concentrations in the two withdrawal groups were significantly higher than those of two heroin administration groups. ADA addiction withdrawal 16223513 When the two withdrawal groups were compared with the control group, there was no significant difference in the concentrations of plasma uric acid and ADA in liver and small intestine, while the concentrations of ADA in plasma and brain were still higher than those of the control group. ADA drug opioid 16223513 The results imply that heroin administration may enhance the catabolism of purine nucleotides in the brain and other tissues by increased concentration of ADA and the effect may last for a long time in the brain.

ADA drug alcohol 7541691 Inclusion of adenosine deaminase (ADA; 1 unit ml 1) during the incubation period to measure cyclic AMP accumulation completely abolished the increase in basal accumulation following chronic ethanol, but did not affect the increase in iloprost stimulation. ADA drug alcohol 7541691 On the other hand ADA partially reversed the increase in forskolin stimulation following chronic ethanol, but even in the presence of high concentrations of ADA (5 units ml 1) the forskolin stimulation remained elevated above control. ADA drug alcohol 7998934 When cells were cultured with 2 units/ml adenosine deaminase, to degrade extracellular adenosine, ethanol induced increases in cyclic AMP production were completely prevented. ADA drug alcohol 7998934 Treatment with adenosine deaminase or CPDX also prevented the decrease in quantity of the alpha subunit protein of G(i) observed in hepatocytes after chronic treatment with ethanol. ADA drug alcohol 3827998 In addition, neither the adenosine deaminase inhibitor erythro 9 (2 hydroxy 3 nonyl) adenine nor the adenosine uptake inhibitor dipyridamole were able to enhance the level of ethanol appropriate responding seen after a low dose of ethanol. ADA addiction sensitization 3888866 While even a single application of ADA 202 718 at the time of sensitization resulted in a stimulation of the hypersensitivity reaction, administration of the compound at the time of challenge was without effect.

TUBB3 drug psychedelics 11906717 Both ibogaine and 18 methoxycoronaridine were antagonists at alpha 3 beta 4 nicotinic receptors and both agents were more potent at this site than at alpha 4 beta 2 nicotinic receptors or at NMDA or 5 HT(3) receptors; 18 methoxycoronaridine was more selective in this regard than ibogaine. TUBB3 addiction relapse 11906717 The data are consistent with the hypothesis that antagonism at alpha 3 beta 4 receptors is a potential mechanism to modulate drug seeking behavior. TUBB3 drug nicotine 11854451 There were no changes in the levels of alpha 4, alpha 5, alpha 6, alpha 7, beta 2, and beta 4 mRNA, or in [(125)I]epibatidine and [(3)H]nicotine binding between +/T and +/+ mice. TUBB3 drug alcohol 9422812 In some cells, agonist induced current responses with the alpha 3 beta 4 subunit combination could be either significantly potentiated or inhibited (range 25% to 237% of control response) by low ethanol concentrations (1 30 mM). TUBB3 drug alcohol 9422812 In general, the alpha 3 beta 2, alpha 4 1 beta 2 and alpha 4 1 beta 4 subunit combinations were less sensitive to low concentrations of ethanol, but respectively showed potentiations of up to 178%, 226% and 154% at high EtOH concentrations.

CHRFAM7A drug nicotine 30089821 The role of nicotinic acetylcholine receptors (nAChR) in nicotine dependence (ND) is well established; CHRNA7, encoding the α7 subunit, has a still uncertain role in ND, although it is implicated in a wide range of neuropsychiatric conditions.

CHRFAM7A drug nicotine 19307444 We found evidence that genetic variation at CHRNA1, CHRNA2, CHRNA7, and CHRNB1 alters susceptibility to nicotine dependence, but we did not replicate any of the most significant single nucleotide polymorphism associations from the NICSNP high density association study.

ADH5 drug alcohol 26848198 Characterization of polymorphisms of genes ADH2, ADH3, ALDH2 and CYP2E1 and relationship to the alcoholism in a Colombian population. ADH5 drug alcohol 26848198 Identify and characterize polymorphisms of genes ADH2, ADH3, ALDH2 and CYP2E1 in a Colombian population residing in the city of Bogotá and determine its possible relationship to the alcoholism. ADH5 drug alcohol 26848198 ADH2, ADH3, ALDH2, and CYP2E1 genotypes a population of 148 individuals with non problematic alcohol and 65 individuals with alcoholism were determined with TaqMan probes and PCR RFLP.

ADH5 addiction dependence 25535445 To determine whether any association exists between polymorphisms of ADH2, ADH3 and ALDH2 and alcohol dependence syndrome in a group of Asian Indians. ADH5 drug alcohol 25535445 Allele frequencies of ADH2*2 (0.50), ADH3*1 (0.67) and ALSH2*2 (0.09) were significantly low in the alcohol dependent subjects. ADH5 drug alcohol 23468174 Humans express at least seven alcohol dehydrogenase (ADH) isoforms that are encoded by ADH gene cluster (ADH7 ADH1C ADH1B ADH1A ADH6 ADH4 ADH5) at chromosome 4. ADH5 drug alcohol 22476623 Numerous association studies have provided compelling evidence that ADH1C gene variation (formerly ADH3) is associated with altered genetic susceptibility to alcoholism and alcohol related liver disease, cirrhosis, or pancreatitis. ADH5 drug alcohol 20617019 A new view of alcohol metabolism and alcoholism role of the high Km Class III alcohol dehydrogenase (ADH3). ADH5 drug alcohol 20617019 Recently, using ADH3 null mutant mice, we demonstrated that ADH3 (Class III), which has a high K(m) and is a ubiquitous enzyme of ancient origin, contributes to systemic alcohol metabolism in a dose dependent manner, thereby diminishing acute alcohol intoxication. ADH5 addiction intoxication 20617019 Recently, using ADH3 null mutant mice, we demonstrated that ADH3 (Class III), which has a high K(m) and is a ubiquitous enzyme of ancient origin, contributes to systemic alcohol metabolism in a dose dependent manner, thereby diminishing acute alcohol intoxication. ADH5 drug alcohol 20617019 Although the activity of ADH3 toward ethanol is usually low in vitro due to its very high K(m), the catalytic efficiency (k(cat)/K(m)) is markedly enhanced when the solution hydrophobicity of the reaction medium increases. ADH5 drug alcohol 20617019 When various doses of ethanol are administered to mice, liver ADH3 activity is dynamically regulated through induction or kinetic activation, while ADH1 activity is markedly lower at high doses (3 5 g/kg). ADH5 drug alcohol 20617019 These data suggest that ADH3 plays a dynamic role in alcohol metabolism, either collaborating with ADH1 or compensating for the reduced role of ADH1. ADH5 drug alcohol 20617019 A complex two ADH model that ascribes total liver ADH activity to both ADH1 and ADH3 explains the dose dependent changes in the pharmacokinetic parameters (beta, CL(T), AUC) of blood ethanol very well, suggesting that alcohol metabolism in mice is primarily governed by these two ADHs. ADH5 drug alcohol 20617019 In patients with alcoholic liver disease, liver ADH3 activity increases, while ADH1 activity decreases, as alcohol intake increases. ADH5 drug alcohol 20617019 These data suggest that chronic binge drinking and the resulting liver disease shifts the key enzyme in alcohol metabolism from low K(m) ADH1 to high K(m) ADH3, thereby reducing the rate of alcohol metabolism. ADH5 addiction intoxication 20617019 These data suggest that chronic binge drinking and the resulting liver disease shifts the key enzyme in alcohol metabolism from low K(m) ADH1 to high K(m) ADH3, thereby reducing the rate of alcohol metabolism. ADH5 drug alcohol 20617019 The interdependent increase in the ADH3/ADH1 activity ratio and AUC may be a factor in the development of alcoholic liver disease. ADH5 drug alcohol 20617019 However, the adaptive increase in ADH3 sustains alcohol metabolism, even in patients with alcoholic liver cirrhosis, which makes it possible for them to drink themselves to death. ADH5 drug alcohol 20617019 Thus, the regulation of ADH3 activity may be important in preventing alcoholism development. ADH5 drug alcohol 19489444 [A new sight on alcohol metabolism and alcoholism role of high Km alcohol dehydrogenase ADH3 (Class III)]. ADH5 drug alcohol 19489444 Recently, we used ADH3 null mutant mice to demonstrate that high Km ADH3 (Class III), a ubiquitous enzyme of ancient origin, contributes to systemic alcohol metabolism dose dependently resulting in a diminution of acute alcohol intoxication. ADH5 addiction intoxication 19489444 Recently, we used ADH3 null mutant mice to demonstrate that high Km ADH3 (Class III), a ubiquitous enzyme of ancient origin, contributes to systemic alcohol metabolism dose dependently resulting in a diminution of acute alcohol intoxication. ADH5 drug alcohol 19489444 Although the ethanol activity of ADH3 in vitro is usually low due to its very high Km, the catalytic efficiency (k(cat)/Km) was markedly enhanced when the solution hydrophobicity of the reaction medium was increased. ADH5 drug alcohol 19489444 By acute administrations of ethanol to mice at various doses, liver ADH3 activity was dynamically regulated through induction or kinetic activation, though ADH1 activity was markedly decreased at higher doses (3 5 g/kg). ADH5 drug alcohol 19489444 These data suggest that ADH3 plays a dynamical share in alcohol metabolism with ADH1, collaborating with it or supplementing the decreased role of ADH1. ADH5 drug alcohol 19489444 The two ADH complex model, which ascribes total liver ADH activity to both ADH1 and ADH3, explained well the dose dependent changes in pharmacokinetic parameters (beta, CL(T), AUC) of blood ethanol, suggesting that alcohol metabolism in mice is primarily governed by the two ADHs. ADH5 drug alcohol 19489444 In patients with alcoholic liver diseases, the liver ADH3 activity increased but the ADH1 activity decreased with an increase in alcohol intake. ADH5 drug alcohol 19489444 These data suggest that heavy and chronic drinking shifts the main enzyme in alcohol metabolism from low Km ADH1 to high Km ADH3 to develop alcoholic liver diseases by the nonlinear increase in AUC due to the decrease of the metabolic rate. ADH5 drug alcohol 19489444 However, the adaptively increased ADH3 keeps the ability of alcohol metabolism even in patients with alcoholic liver cirrhosis and make possible for them to keep drinking to death. ADH5 drug alcohol 19489444 Therefore, the regulation of ADH3 activity may be important to prevent the development of alcoholism. ADH5 drug alcohol 18996923 After controlling for rs1229984, an independent association was observed between rs1042026 (ADH1B) and alcohol intake (P=4.7 x 10( 5)) and suggestive associations (P<0.001) between alcohol consumption phenotypes and rs1693482 (ADH1C), rs1230165 (ADH5) and rs3762894 (ADH4). ADH5 drug alcohol 18207224 The primary isozyme of alcohol dehydrogenase (ADH) in rat liver, ADH 3, had a similar Km and higher activity in liver preparations from juveniles. ADH5 drug alcohol 17629074 The aim of the present study was to find in the Polish population the ADH3 genotypes, which are likely to be responsible for higher susceptibility to alcohol disease of the liver and chronic alcohol pancreatitis. ADH5 drug alcohol 17629074 The genotype ADH3*1/ADH3*1 was found to be significantly more frequent in alcohol abusers compared to non drinkers. ADH5 drug alcohol 17629074 The examinations of the group of alcohol abusers showed that the genotype ADH3*2/ADH3*2 occurred statistically significantly less frequently in patients with chronic pancreatitis than those without alimentary lesions and patients with cirrhosis. ADH5 drug alcohol 17454860 We determined the allele and genotype of ADH2, ADH3 and ALDH2 in 198 subjects: 57 with alcohol cirrhosis, 44 with alcohol chronic pancreatitis and 43 "healthy alcoholics"; 54 healthy non drinkers served as controls. ADH5 drug alcohol 17454860 The ADH2*1 and the ADH3*1 alleles were statistically more common among patients who abuse alcohol in comparison with the controls. ADH5 drug alcohol 17454860 The ADH2*1/*1 and the ADH3*1/*1 genotypes were statistically significantly more common among the patients who abuse alcohol than in the control group. ADH5 drug alcohol 17454860 Patients with the ADH3*1 allele and the ADH3*1/*1 genotype started to abuse alcohol significantly earlier in comparison to the patients with the ADH3*2 allele and the ADH3*2 /*2 genotype. ADH5 drug alcohol 17454860 In the Polish population examined, the ADH3*1 allele and the ADH3*1/*1 genotype are conducive to the development of alcoholism, alcohol liver cirrhosis and alcohol chronic pancreatitis. ADH5 drug alcohol 17454860 The ADH3*1 allele and the ADH3*1/*1 genotype are conducive to alcohol abuse starting at a younger age. ADH5 drug alcohol 17134660 This study sought to determine whether an association exists between ADH (ADH1C previously ADH3, ADH1B*2 previously ADH2*2) genotypes, alcohol dependence, drinking history, and liver function tests in the two major ethnic groups of Trinidad and Tobago (TT). ADH5 addiction dependence 17134660 This study sought to determine whether an association exists between ADH (ADH1C previously ADH3, ADH1B*2 previously ADH2*2) genotypes, alcohol dependence, drinking history, and liver function tests in the two major ethnic groups of Trinidad and Tobago (TT). ADH5 drug alcohol 16431092 In vivo contribution of Class III alcohol dehydrogenase (ADH3) to alcohol metabolism through activation by cytoplasmic solution hydrophobicity. ADH5 drug alcohol 16431092 In this study, we used Adh3 null mutant mice to demonstrate that Class III ADH (ADH3), a ubiquitous enzyme of ancient origin, contributes to alcohol metabolism in vivo dose dependently resulting in a diminution of acute alcohol intoxication. ADH5 addiction intoxication 16431092 In this study, we used Adh3 null mutant mice to demonstrate that Class III ADH (ADH3), a ubiquitous enzyme of ancient origin, contributes to alcohol metabolism in vivo dose dependently resulting in a diminution of acute alcohol intoxication. ADH5 drug alcohol 16431092 Although the ethanol oxidation activity of ADH3 in vitro is low due to its very high Km, it was found to exhibit a markedly enhanced catalytic efficiency (kcat/Km) toward ethanol when the solution hydrophobicity of the reaction medium was increased with a hydrophobic substance. ADH5 drug alcohol 16431092 So, the in vivo contribution of high Km ADH3 to alcohol metabolism is likely to involve activation in a hydrophobic solution. ADH5 drug alcohol 16431092 Thus, the present study demonstrated that ADH3 plays an important role in systemic ethanol metabolism at higher levels of blood ethanol through activation by cytoplasmic solution hydrophobicity. ADH5 drug alcohol 16239350 To find the ADH3 genotypes in the Polish population likely to be responsible for higher susceptibility to alcohol disease of the liver and chronic alcohol pancreatitis.

ADH5 drug alcohol 16239350 The examinations of the group of alcohol abusers showed that the genotype ADH3*2/ADH3*2 occurred statistically significantly less frequently in patients with chronic pancreatitis than in those without alimentary lesions (healthy drinkers). ADH5 drug alcohol 16239350 Variations in ADH3 genotypes may account for some of the differences in prevalence of alcohol dependence between genders in the Polish population.

ADH5 drug alcohol 15863807 The authors examined the genetic polymorphisms of alcohol dehydrogenase 2 and 3 (ADH2 and ADH3) and aldehyde dehydrogenase (ALDH2) in patients diagnosed as having Cloninger's type I or type II alcoholism. ADH5 drug alcohol 15863807 Seventy two alcoholic men and 38 nonalcoholic, healthy men were tested for the distribution of genotypes and alleles of ADH2, ADH3, and ALDH2. ADH5 drug alcohol 15863807 The frequencies of ADH2*1 and ADH3*2 alleles were significantly higher in men with type II alcoholism than in men with type I alcoholism and healthy men. ADH5 drug alcohol 12884000 In the current study, variants at ADH1B (previously ADH2), ADH1C (previously ADH3), and ALDH2 were assayed in DNA extracts from participants belonging to a Southwest American Indian tribe (n=490) with a high prevalence of alcoholism. ADH5 drug alcohol 12750236 Alcohol is a probable risk factor with regard to colorectal neoplasm and is metabolized to the carcinogen acetaldehyde by the genetically polymorphic alcohol dehydrogenase 3 (ADH3) enzyme. ADH5 drug alcohol 12750236 We evaluated whether the association between alcohol and colorectal adenomas is modified by ADH3 polymorphism. ADH5 drug alcohol 12750236 Among subjects in the highest tertile of alcohol consumption, those with the ADH3*1/*1 genotype were at higher risk (OR, 1.8; 95% CI, 1.0 3.1) than those with other ADH3 genotypes (OR, 1.2; 95% CI, 0.7 1.9) when compared with those in the lowest tertile with ADH3*1/*2 or ADH3*2/*2 genotypes. ADH5 drug alcohol 12750236 ADH3 polymorphism may modify the association between alcohol consumption and colorectal adenomas. ADH5 drug alcohol 12710951 The ADH3*2 and CYP2E1 c2 alleles increase the risk of alcoholism in Mexican American men. ADH5 drug alcohol 12710951 To identify the association between the polymorphisms of genes encoding alcohol metabolizing enzymes and alcoholism, the alcohol dehydrogenase 2 (ADH2), alcohol dehydrogenase 3 (ADH3), aldehyde dehydrogenase 2 (ALDH2), and cytochrome P450 2E1 (CYP2E1) genes were studied in 101 male Mexican American alcoholics. ADH5 drug alcohol 12710951 A strong association was found between ADH3 genotype and alcoholism; the percentage of subjects who carry the ADH3*2 allele was significantly higher in alcoholics (64.4%) than controls (50%). ADH5 drug alcohol 12710951 Among 101 alcoholics, only 18 subjects carry neither ADH3*2 nor CYP2E1 c2 alleles. ADH5 drug alcohol 12710951 Taken together, ADH3*2 and CYP2E1 c2/C alleles might independently contribute to the development of alcoholism in Mexican American men. ADH5 drug alcohol 12505800 Two alcohol dehydrogenase genes (ADH2 and ADH3 on chromosome 4) and one aldehyde dehydrogenase gene (ALDH2 on chromosome 12) exhibit functional polymorphisms. ADH5 drug alcohol 12505800 The goal of this study was to determine whether any associations exist between the ADH2, ADH3, and ALDH2 polymorphisms and alcohol dependence in a group of Native Americans.

ADH5 drug alcohol 11752857 Alcohol dehydrogenase type 3 (ADH3) and the risk of bladder cancer. ADH5 drug alcohol 11752857 After correction for sex, age and smoking, ORs for ADH3 genotype and alcohol intake were 2.10 (1.05 4.22) and 1.21 (0.60 2.44), respectively. ADH5 drug nicotine 11752857 After correction for sex, age and smoking, ORs for ADH3 genotype and alcohol intake were 2.10 (1.05 4.22) and 1.21 (0.60 2.44), respectively. ADH5 drug alcohol 11752857 Although moderate drinkers with the gamma1gamma1 genotype seem to have the highest risk, we did not get a clear indication that ADH3 genotype modifies the relationship between alcohol intake and bladder cancer. ADH5 drug alcohol 11584143 In view of this association and the known genetic influences on both alcohol pharmacokinetics and alcohol dependence, it is probable that part of the heritability of dependence is mediated by genes (other than the known ADH2 and ADH3 polymorphisms) affecting alcohol metabolism. ADH5 addiction dependence 11584143 In view of this association and the known genetic influences on both alcohol pharmacokinetics and alcohol dependence, it is probable that part of the heritability of dependence is mediated by genes (other than the known ADH2 and ADH3 polymorphisms) affecting alcohol metabolism. ADH5 drug alcohol 10630602 An alcohol dependent patient was identified to be ALDH2*2/*2, ADH2*2/*2, and ADH3*1/*2. ADH5 drug alcohol 10597438 Evidence for linkage to the ALDX1 alcoholism phenotype at the ADH3 functional candidate gene was increased in the late onset subgroup (Bonferroni corrected significance level < 0.002), as compared with the unstratified sample that replicated COGA linkage obtained in the same analysis; there was no evidence for linkage at this locus in the early onset subgroup. ADH5 drug alcohol 10597410 For the "alcoholism free" outcome, we found significant linkage signals at D4S2457, D41651 (both flank ADH3), D11S2359, and D16S47 and significant linkage disequilibrium signals at D4S2361, FABP2, D11S2359, D19S431 and D19S47 D19S198 D19S601. ADH5 drug alcohol 10235293 The different genotypes at the genes encoding the enzymes involved in alcohol metabolism, class one alcohol dehydrogenase (ADH2 and ADH3) and mitochondrial aldehyde dehydrogenase (ALDH2), have previously been shown to confer different predispositions to the development of alcoholism in Chinese Han males (Thomasson et al., 1991; Chen WJ et al., 1996; Chen CC et al., unpublished data). ADH5 drug alcohol 10235293 Therefore, association studies of alcoholism in Chinese Han might be more sensitive if controlled for the genotypes of ADH2,ADH3, and ALDH2, when other loci, such as DRD2, are examined. ADH5 drug alcohol 10235293 These tests included considering the high risk (ADH2*1/*1; *1/*2; ADH3*1/*2; *2/*2; and ALDH2*1/*1) and the low risk (ADH2*2/*2; ADH3*1/*1; and ALDH2*1/*2; *2/*2) groups of alcoholics, as well as nonalcoholic controls. ADH5 drug alcohol 10235293 After stratification by the relevant genotypes of ADH2, ADH3, and ALDH2 no significant association exists between the genetic variants at the DRD2 locus and alcoholism in the Chinese Han population. ADH5 drug alcohol 9731720 Caucasians are polymorphic at only two of these gene loci cytochrome P450 2E1 (CYP2E1) and alcohol dehydrogenase 3 (ADH3). ADH5 drug alcohol 9731720 We examined the frequency of the RsaI polymorphism of CYP2E1 and ADH3 genotype in 264 patients with alcoholic liver disease and 121 local control individuals. ADH5 drug alcohol 9731720 This risk appears to be particularly manifest in individuals carrying the ADH3*2 allele, presumably reflecting increased metabolism of ethanol by CYP2E1. ADH5 drug alcohol 9731720 In the absence of the c2 allele, ADH3 genotype does not influence the risk of advanced alcoholic liver disease but, in males at least, may influence the risk of alcoholism. ADH5 drug alcohol 9373704 The purpose of this paper is to assemble and evaluate existing data on the effect of genetic variation in ADH2 and ADH3 on the risk of alcohol dependence, and on the risk of alcoholic liver disease. ADH5 addiction dependence 9373704 The purpose of this paper is to assemble and evaluate existing data on the effect of genetic variation in ADH2 and ADH3 on the risk of alcohol dependence, and on the risk of alcoholic liver disease. ADH5 drug alcohol 9373704 ADH3 variation also has significant effects on alcohol dependence, which may be due to linkage to ADH2; the ADH3 effect differs significantly between Asian and European subjects. ADH5 addiction dependence 9373704 ADH3 variation also has significant effects on alcohol dependence, which may be due to linkage to ADH2; the ADH3 effect differs significantly between Asian and European subjects. ADH5 drug alcohol 9066994 In this report we determined the genotypes for three genes, ADH2, ADH3, and ALDH2 among subjects with alcohol dependence (n = 159) and ethnically matched normal controls (n = 149) for the four largest aboriginal groups (Atayal, Ami, Bunun, and Paiwan) in Taiwan. ADH5 addiction dependence 9066994 In this report we determined the genotypes for three genes, ADH2, ADH3, and ALDH2 among subjects with alcohol dependence (n = 159) and ethnically matched normal controls (n = 149) for the four largest aboriginal groups (Atayal, Ami, Bunun, and Paiwan) in Taiwan. ADH5 drug alcohol 8904964 The influences of estimated body water, recent drinking history, recent smoking history, polymorphism at the ADH2 and ADH3 loci, family history of alcoholism, and percentage Native American heritage on alcohol elimination rate were determined using multiple regression analyses. ADH5 drug nicotine 8904964 The influences of estimated body water, recent drinking history, recent smoking history, polymorphism at the ADH2 and ADH3 loci, family history of alcoholism, and percentage Native American heritage on alcohol elimination rate were determined using multiple regression analyses. ADH5 drug alcohol 8773821 Alcohol metabolising genes and alcoholism among Taiwanese Han men: independent effect of ADH2, ADH3 and ALDH2. ADH5 drug alcohol 8773821 The association of ALDH2 and ADH2 with the development of alcoholism was found to be independent of each other and has been replicated in different Asian populations, while the effect of ADH3 is less studied. ADH5 drug alcohol 8773821 Multiple logistic regression was then applied to assess the contribution of ADH3 to alcoholism by controlling the effect of ALDH2 and ADH2. ADH5 drug alcohol 8773821 The results of multivariate analyses demonstrated that the odds ratios for an increment of one allele of ADH2*1, ADH3*2 and ALDH2*1 in the development of alcoholism were 4.18, 3.82, and 6.89, respectively. ADH5 drug alcohol 8651462 A comparison of the genotypes of ALDH2, ADH2, ADH3, and cytochrome P 4502E1 between alcoholics and nonalcoholics. ADH5 drug alcohol 8651462 We examined the genotypes of the aldehyde dehydrogenase (ALDH) 2, alcohol dehydrogenase (ADH) 2, ADH3, and P 4502E1 loci of 53 alcoholics and 97 nonalcoholics. ADH5 drug alcohol 8651462 Our study revealed differences in the allelic frequencies of the ALDH2, ADH2, and ADH3 loci between alcoholics and nonalcoholics. ADH5 drug alcohol 8651462 For alcoholics with both homozygous ALDH2*1/1 and heterozygous ALDH2*1/2 genotypes, it was found that ADH2 and ADH3 played important rates. ADH5 drug alcohol 7943668 Genetic variation at two polymorphic alcohol dehydrogenase loci, ADH2 and ADH3, and at the polymorphic mitochondrial aldehyde dehydrogenase locus, ALDH2, may influence the risk of developing alcoholism by modulating the rate of elimination of ethanol and the rate of formation and elimination of acetaldehyde. ADH5 drug alcohol 8462548 These results allow us to assume an important role of rat liver ADH 3 in the mechanism of alcohol addiction. ADH5 addiction addiction 8462548 These results allow us to assume an important role of rat liver ADH 3 in the mechanism of alcohol addiction. TRD addiction relapse 32616208 While standard antidepressants are at least partly effective for the short term treatment of acute depressive episodes of MDD, many patients relapse within 6 months of apparent clinical remission, with faster and higher rates observed in those with treatment resistant depression (TRD). TRD drug psychedelics 32616208 More recently, maintenance of antidepressant effects beyond the initial acute (induction) treatment period has been shown with esketamine nasal spray, an enantiomer of ketamine, in conjunction with an oral antidepressant in three phase 2/3 registration studies (SYNAPSE, SUSTAIN 1, SUSTAIN 2) of adult patients with TRD.

TRD addiction withdrawal 32331032 No indication of drug specific withdrawal symptoms was seen after stopping up to 1 year of intermittent treatment with ESK nasal spray for TRD. TRD drug psychedelics 32240970 Intravenous ketamine, a dissociative anesthetic that induces complex downstream effects via NMDARs, rapidly reduces depressive and suicidal symptoms in treatment resistant depression (TRD), as demonstrated by several trials. TRD drug psychedelics 32240970 Recently, the United States Food and Drug Administration (FDA) approved an intranasal version of ketamine (esketamine) for TRD. TRD drug psychedelics 32061748 Ketamine, a dissociative anesthetic and psychedelic compound, has revolutionized the field of psychopharmacology by showing robust, and rapid acting antidepressant activity in patients suffering from major depressive disorder (MDD), suicidal tendencies, and treatment resistant depression (TRD). TRD drug benzodiazepine 31759333 Thirty seven participants with treatment resistant depression (TRD) and baseline SI first received a single ketamine infusion during a randomized, double blind crossover with midazolam. TRD drug psychedelics 31759333 Thirty seven participants with treatment resistant depression (TRD) and baseline SI first received a single ketamine infusion during a randomized, double blind crossover with midazolam. TRD drug psychedelics 31759333 In TRD, single and repeated ketamine infusions resulted in decreases in SI which were maintained with once weekly maintenance infusions. TRD drug alcohol 31656053 Increased risks for TRD were found ≤ 180 days before treatment start for the subcategories of sedative use (aOR = 2.37; 1.88 2.99), opioids (aOR = 2.02; 1.48 2.75), alcohol (aOR = 1.77; CI = 1.59 1.98) and combined substance use (aOR = 2.31; 1.87 2.99). TRD drug opioid 31656053 Increased risks for TRD were found ≤ 180 days before treatment start for the subcategories of sedative use (aOR = 2.37; 1.88 2.99), opioids (aOR = 2.02; 1.48 2.75), alcohol (aOR = 1.77; CI = 1.59 1.98) and combined substance use (aOR = 2.31; 1.87 2.99). TRD drug psychedelics 31514448 The N methyl D aspartate receptor (NDMAR) antagonist ketamine has been shown to rapidly improve symptoms of depression in patients with TRD. TRD drug psychedelics 31514448 We examined the relationship between childhood maltreatment using the Childhood Trauma Questionnaire (CTQ) and treatment response using the Quick Inventory of Depressive Symptoms Self Report (QIDS SR) in TRD patients receiving intravenous ketamine at a community outpatient clinic. TRD drug psychedelics 31514448 In contrast to conventional antidepressants, ketamine could be more effective in TRD patients with more childhood trauma burden, perhaps due to ketamine's proposed ability to block trauma associated behavioral sensitization. TRD addiction sensitization 31514448 In contrast to conventional antidepressants, ketamine could be more effective in TRD patients with more childhood trauma burden, perhaps due to ketamine's proposed ability to block trauma associated behavioral sensitization.

TRD drug psychedelics 31494365 Subjects with TRD were randomized to a single infusion of one of several doses of intravenous ketamine, or midazolam. TRD drug psychedelics 31374046 A recent striking advance in the treatment of depression has been the finding of rapid antidepressant effects in over 70% of patients with treatment resistant depression (TRD) using ketamine. TRD drug psychedelics 31282772 While the efficacy of esketamine compared to off label use of racemic ketamine remains unclear, both esketamine's approval for use in TRD and longer term safety data may position it preferentially above racemic ketamine, although factors such as cost and monitoring requirements may limit its use. TRD addiction addiction 31282772 While questions remain regarding duration and frequency of treatment, as well as addictive potential, esketamine is a novel treatment option offering new hope for TRD. TRD drug psychedelics 30858518 The N methyl D aspartate (NMDA) receptor antagonist ketamine is associated with rapid but transient antidepressant effects in patients with treatment resistant unipolar depression (TRD). TRD drug psychedelics 30858518 Based on work suggesting that ketamine and lithium may share overlapping mechanisms of action, we tested lithium compared to placebo as a continuation strategy following ketamine in subjects with TRD. TRD drug psychedelics 30858518 Forty seven participants with TRD were enrolled in the study and underwent an initial ketamine infusion, of whom 34 participants were deemed to have at least a partial antidepressant response and were eligible for randomization. TRD drug psychedelics 30572160 Patients with TRD seeking clinical treatment are randomized (1:1) to receive ECT (thrice weekly) or intravenous ketamine (twice weekly) for 3 5 weeks. TRD addiction relapse 30572160 Patients with TRD seeking clinical treatment are randomized (1:1) to receive ECT (thrice weekly) or intravenous ketamine (twice weekly) for 3 5 weeks. TRD drug psychedelics 30450382 In this review, we will discuss the safety of repeated treatments with ketamine for patients with treatment resistant depression (TRD), a condition in which patients with major depression do not show any clinical improvements following treatments with at least two antidepressant drugs. TRD drug psychedelics 30450382 Numerous small clinical studies have shown that a single, low dose ketamine infusion can rapidly alleviate depressive symptoms and thoughts of suicidality in patients with TRD, and these effects can last for about one week. TRD drug psychedelics 30450382 Additionally, during ketamine infusions, many TRD patients report hallucinations and feelings of dissociation and depersonalization, and therefore the effects of repeated treatments of ketamine on cognition must be further examined. TRD drug psychedelics 30450382 Although more work about the safety of ketamine is warranted, we hope this review will bring some answers about the safety of treating TRD with repeated ketamine infusions. TRD drug psychedelics 30427812 However, the evidence for long term maintenance ketamine therapy for treatment resistant depression (TRD) and suicidal behavior is limited. TRD drug psychedelics 30427812 Two cases of TRD achieved functional remission with long term maintenance ketamine treatment. TRD drug benzodiazepine 30427812 Factors that may contribute to lack of effectiveness of serial ketamine include inadequate mood stabilization in TRD in bipolar spectrum diagnoses, concomitant benzodiazepine use, complex comorbidities, and adverse effects such as significant hypertension and severe dissociation. TRD drug psychedelics 30427812 Factors that may contribute to lack of effectiveness of serial ketamine include inadequate mood stabilization in TRD in bipolar spectrum diagnoses, concomitant benzodiazepine use, complex comorbidities, and adverse effects such as significant hypertension and severe dissociation. TRD drug psychedelics 30427812 Future systematic controlled studies are warranted to establish the efficacy and safety profile of long term ketamine as maintenance therapy for TRD with suicidal behavior. TRD addiction relapse 30055578 Time from relapse to death (TRD) was calculated from date of recurrence to date of death. TRD drug psychedelics 30004254 Ketamine has been studied in adults with TRD, but little information is available for adolescents. TRD drug psychedelics 30004254 This study investigated efficacy and tolerability of intravenous ketamine in adolescents with TRD, and explored clinical response predictors. TRD drug psychedelics 30004254 Adolescents, 12 18 years of age, with TRD (failure to respond to two previous antidepressant trials) were administered six ketamine (0.5 mg/kg) infusions over 2 weeks. TRD drug psychedelics 30004254 These results demonstrate the potential role for ketamine in treating adolescents with TRD. TRD drug psychedelics 29727073 The present study examined the efficacy, safety, and durability of repeated ketamine infusions for the treatment of comorbid posttraumatic stress disorder (PTSD) and treatment resistant depression (TRD) in a sample of veterans. TRD drug psychedelics 29727073 This report suggests that repeated ketamine treatments are safe and may represent an efficacious treatment for individuals with comorbid PTSD and TRD. TRD drug psychedelics 29542371 The drug formulation, the delivery device, the insufflation technique and individual patient factors play an important role in tolerability and efficacy when using IN ketamine for TRD. TRD drug psychedelics 28124853 While the molecular basis of ketamine's therapeutic effect has not been fully determined, it has shown to effectively and swiftly mitigate the symptoms of TRD. TRD drug psychedelics 28124853 Despite this, ketamine remains a promising pharmacotherapy for TRD and further investigation is required. TRD drug psychedelics 27189960 Ketamine is a rapidly acting antidepressant in patients with treatment resistant depression (TRD). TRD drug psychedelics 27189960 Preclinical data suggest that blockade of metabotropic glutamate (mGlu2/3) receptors shares many overlapping features and mechanisms with ketamine and may also provide rapid efficacy for TRD patients. TRD drug psychedelics 26509083 Ketamine and repetitive transcranial magnetic stimulation (rTMS) have useful roles in TRD, but their utility in long term is unknown. TRD drug psychedelics 26509083 Considering the limitations of existing treatment options, including those of ketamine and rTMS when used as the sole modality of treatment, we suggest a "tiered approach for TRD" by combining ketamine and rTMS (alone or along with antidepressants) for rapid remission of acute depression symptoms and to use DepS Y MBCT for maintaining remission and preventing relapse.

TRD drug psychedelics 25539512 A single subanesthetic infusion of the N methyl D aspartate (NMDA) receptor antagonist ketamine has rapid and potent antidepressant properties in treatment resistant major depressive disorder (TRD). TRD drug psychedelics 25539512 Fifty two TRD subjects received an open label infusion of ketamine (0.5mg/kg over 40 minutes), and, four to six hours post infusion, were randomized to either flexible dose (100 200mg/day) riluzole or placebo in the following proportions: Family History Positive (FHP) riluzole (n = 10), FHP placebo (n = 9), Family History Negative (FHN) riluzole (n = 16), and FHN placebo (n = 17). TRD drug psychedelics 25539512 Ketamine's extended antidepressant durability in FHP TRD should be considered in the design and analysis of ketamine depression trials. TRD drug psychedelics 24963561 The N methyl D aspartate glutamate receptor antagonist ketamine has demonstrated rapid antidepressant effects in treatment resistant depression (TRD). TRD drug psychedelics 24963561 However, evaluation of ketamine's neurocognitive aspects in TRD has started to be explored. TRD drug psychedelics 24963561 Six IV infusions of 0.5 mg/Kg ketamine over 40 min were conducted on a Monday Wednesday Friday schedule during a 12 d period on 15 patients with TRD followed by a 4 wk observational period. TRD drug psychedelics 24963561 Our findings suggest a potential baseline neurocognitive predictor of ketamine response and the apparently lack of short term neurocognitive impairment after completion of six ketamine infusions in TRD. TRD drug psychedelics 24434008 The recent discovery of ketamine's unique antidepressant properties, with rapid onset of response and high rate of responders opens new perspectives for treatment resistant depression (TRD). TRD drug psychedelics 24268616 Safety and efficacy of repeated ketamine infusions were attained without medication free state in patients with TRD. TRD drug psychedelics 22840761 A previous report including 10 participants with treatment resistant major depression (TRD) found that six ketamine infusions resulted in a sustained antidepressant effect. TRD drug psychedelics 22840761 Participants with TRD (n = 24) underwent a washout of antidepressant medication followed by a series of up to six IV infusions of ketamine (.5 mg/kg) administered open label three times weekly over a 12 day period. TRD drug psychedelics 22840761 Ketamine was associated with a rapid antidepressant effect in TRD that was predictive of a sustained effect. TRD drug psychedelics 22303887 The first generation of studies in patients with treatment resistant depression (TRD) reported the safety and acute efficacy of a single subanaesthetic dose (0.5 mg/kg) of intravenous ketamine. TRD drug psychedelics 22303887 Given the potential risks of ketamine, safety considerations will ultimately determine whether this old drug is successfully repositioned as a new therapy for TRD. TRD drug psychedelics 22298121 The N methyl D aspartate antagonist ketamine has rapid antidepressant effects in patients with treatment resistant major depression (TRD); these effects have been reported to last for 1 week in some patients. TRD drug psychedelics 22298121 Forty two subjects (18 65) with TRD and a Montgomery Asberg Depression Rating Scale (MADRS) score of ≥ 22 received a single intravenous infusion of ketamine (0.5 mg/kg). TRD drug psychedelics 19897179 A single subanesthetic (intravenous) IV dose of ketamine might have rapid but transient antidepressant effects in patients with treatment resistant depression (TRD). TRD drug psychedelics 19897179 Here we tested the tolerability, safety, and efficacy of repeated dose open label IV ketamine (six infusions over 12 days) in 10 medication free symptomatic patients with TRD who had previously shown a meaningful antidepressant response to a single dose. TRD drug psychedelics 19897179 These pilot findings suggest feasibility of repeated dose IV ketamine for the acute treatment of TRD. TRD drug psychedelics 19288975 ketamine is well tolerated in TRD, and may have rapid and sustained antidepressant properties. TRD addiction reward 17689921 To assess strain differences in temporal processing, males and females of the SHR, Wistar Kyoto (WKY), and Sprague Dawley (SD) strains were compared on two timing tasks: one requiring maintenance of a lever press for 10 14 s (TRD, temporal response differentiation) and the other requiring withholding of a lever press for 10 14 s (DRL, differential reinforcement of low rates). TRD addiction reward 11704259 As adults, subjects were tested under one of two paradigms a differential reinforcement of low response rate (DRL) task requiring that subjects withhold a lever press response for 10 14 s or a temporal response differentiation (TRD) task requiring that subjects maintain a lever press response for 10 14 s. Training and steady state performance of the DRL and TRD tasks were not significantly altered by DFMO treatment. TRD drug opioid 11124404 The present series of experiments compared the effects of physostigmine, caffeine, pentobarbital, morphine, and naloxone on the performance of a differential reinforcement of low rates with limited hold (DRL LH) and a temporal response differentiation (TRD) task.

TRD addiction reward 10719798 Tasks included: temporal response differentiation (TRD) to assess timing behavior; differential reinforcement of low response rates (DRL) to assess timing and response inhibition; incremental repeated acquisition (IRA) to assess learning; conditioned position responding (CPR) to assess auditory, visual, and position discrimination; and progressive ratio (PR) to assess motivation. TRD drug alcohol 10719798 Ethanol (0.0, 0.5, 1.0, 1.5, 2.0, and 3.0 g/kg via orogastric gavage) reduced accuracy and/or percent task completed for the TRD, DRL, and CPR tasks. TRD drug nicotine 10672976 The present experiment assessed nicotine's effects on complex cognitive processes using a variety of operant tasks in rats, including incremental repeated acquisition (IRA) to assess learning; conditioned position responding (CPR) to assess auditory, visual, and position discrimination; progressive ratio (PR) to assess motivation; temporal response differentiation (TRD) to assess timing; and differential reinforcement of low response rates (DRL) to assess timing and response inhibition.

TRD drug nicotine 10672976 For TRD, nicotine had a U shaped dose effect on accuracy, but failed to shift the mode of the TRD response distribution. TRD drug benzodiazepine 8848440 Acute administration of diazepam (0.25 4.0 mg/kg, IP) altered TRD performance only. TRD addiction reward 8516351 The effects of acute pentobarbital treatment were assessed using a complex operant test battery containing five tasks in which correct performance is thought to depend upon processes associated with short term memory and attention [delayed matching to sample (DMTS)], color and position discrimination [conditioned position responding (CPR)], motivation [progressive ratio (PR)], time perception [temporal response differentiation (TRD)], and learning [incremental repeated acquisition (IRA)]. TRD drug opioid 2017457 The acute effects of morphine sulfate were assessed using a battery of complex food reinforced operant tasks that included temporal response differentiation (TRD, n = 5), delayed matching to sample (DMTS, n = 6), progressive ratio (PR, n = 9), incremental repeated acquisition (IRA, n = 9), and conditioned position responding (CPR, n = 7) tasks.

TRD drug opioid 2017457 These results indicate that in monkeys, the performance of operant tasks designed to model learning ability (IRA), time perception (TRD) and motivation (PR) are more sensitive to the disruptive effects of morphine than is performance in tasks designed to model short term memory and attention (DMTS). TRD addiction reward 2017457 These results indicate that in monkeys, the performance of operant tasks designed to model learning ability (IRA), time perception (TRD) and motivation (PR) are more sensitive to the disruptive effects of morphine than is performance in tasks designed to model short term memory and attention (DMTS). TRD drug amphetamine 2345755 The acute effects of d amphetamine were assessed using a battery of complex food reinforced operant tasks that included responding in delayed matching to sample (DMTS, n = 6), conditioned position responding (CPR, n = 7), progressive ratio (PR, n = 8), temporal response differentiation (TRD, n = 4), and incremental repeated acquisition (IRA, n = 9) tasks. TRD addiction reward 2345755 The acute effects of d amphetamine were assessed using a battery of complex food reinforced operant tasks that included responding in delayed matching to sample (DMTS, n = 6), conditioned position responding (CPR, n = 7), progressive ratio (PR, n = 8), temporal response differentiation (TRD, n = 4), and incremental repeated acquisition (IRA, n = 9) tasks. TRD drug amphetamine 2345755 Thus, the relative sensitivities of these tasks for detecting d amphetamine behavioral effects were IRA = TRD greater than PR = DMTS greater than CPR. TRD drug benzodiazepine 2626452 The acute effects of diazepam (Valium) were assessed using a battery of complex food reinforced operant tasks that included responding in delayed matching to sample (DMTS, n = 5), conditioned position response (CPR, n = 7) progressive ratio (PR, n = 8), temporal response differentiation (TRD, n = 4), and incremental repeated acquisition (IRA, n = 9) tests.

TRD drug benzodiazepine 2626452 Diazepam (0.25 4.0 mg/kg IV) produced significant dose dependent decreases in the number of reinforcers obtained in the TRD and IRA tasks only. TRD drug cannabinoid 2770412 The acute behavioral effects of marijuana smoke were assessed in rhesus monkeys using a battery of food reinforced complex operant tasks that included incremental repeated acquisition (IRA, n = 9), conditioned position responding (CPR, n = 8), progressive ratio (PR, n = 8), delayed matching to sample (DMTS, n = 6), and temporal response differentiation responding (TRD, n = 3).

TRD drug cannabinoid 2770412 In the three animals performing under all five schedules, the relative sensitivities for detecting marijuana behavioral effects were DMTS = TRD greater than IRA = CPR greater than PR. TRD drug cannabinoid 2834536 Acute effects of delta 9 tetrahydrocannabinol (THC) were assessed using a battery of food reinforced complex operant tasks that included responding under delayed matching to sample (DMTS, n = 6), conditioned position response (CPR, n = 8) progressive ratio (PR, n = 8), temporal response differentiation (TRD, n = 3) and incremental repeated acquisition (IRA, n = 9) tasks. TRD addiction reward 2834536 Acute effects of delta 9 tetrahydrocannabinol (THC) were assessed using a battery of food reinforced complex operant tasks that included responding under delayed matching to sample (DMTS, n = 6), conditioned position response (CPR, n = 8) progressive ratio (PR, n = 8), temporal response differentiation (TRD, n = 3) and incremental repeated acquisition (IRA, n = 9) tasks. TRD drug cannabinoid 2834536 The relative sensitivities of these tests for detecting THC behavioral effects were thus TRD greater than IRA = DMTS = CPR greater than PR.

TAAR1 addiction sensitization 32407821 Effects of a trace amine associated receptor 1 agonist RO 5263397 on ethanol induced behavioral sensitization. TAAR1 drug alcohol 32407821 While TAAR1 is critically involved in the modulation of dopamine, there is little evidence indicating that TAAR1 could play a role in behavioral effects of ethanol. TAAR1 drug alcohol 32407821 By using the animal model of behavioral sensitization induced by ethanol in mice, the present study was performed to investigate whether the activation of TAAR1 would affect the behavioral plasticity of ethanol.

TAAR1 drug amphetamine 26640076 Importantly, saline treated and AMPH treated mice lacking TAAR1 demonstrated significant alterations in the total levels and phosphorylation of the critical subunit of NMDA glutamate receptors, GluN1, in the striatum, suggesting a role of TAAR1 in the modulation of frontostriatal glutamate transmission; this effect could underlie the observed alterations in conditioning processes. TAAR1 drug amphetamine 26640076 In conclusion, our data suggest that TAAR1 receptors play an inhibitory role with respect to conditioned responses to AMPH by modulating, at least in part, corticostriatal glutamate transmission.

TAAR1 drug amphetamine 26302754 Methamphetamine induces trace amine associated receptor 1 (TAAR1) expression in human T lymphocytes: role in immunomodulation. TAAR1 drug amphetamine 26302754 Methamphetamine induces trace amine associated receptor 1 (TAAR1) expression in human T lymphocytes: role in immunomodulation. TAAR1 drug amphetamine 26302754 For the first time, our studies have illustrated that there is an induction of TAAR1 mRNA expression in resting T lymphocytes in response to methamphetamine. TAAR1 drug amphetamine 26302754 Methamphetamine treatment for 6 h significantly increased TAAR1 mRNA expression (P < 0.001) and protein expression (P < 0.01) at 24 h. With the use of TAAR1 gene silencing, we demonstrate that methamphetamine induced cAMP, a classic response to methamphetamine stimulation, is regulated via TAAR1. TAAR1 drug amphetamine 26302754 We also show by TAAR1 knockdown that the down regulation of IL 2 in T cells by methamphetamine, which we reported earlier, is indeed regulated by TAAR1. TAAR1 drug amphetamine 26302754 Our results also show the presence of TAAR1 in human lymph nodes from HIV 1 infected patients, with or without a history of methamphetamine abuse. TAAR1 drug amphetamine 26302754 TAAR1 expression on lymphocytes was largely in the paracortical lymphoid area of the lymph nodes with enhanced expression in lymph nodes of HIV 1 infected methamphetamine abusers rather than infected only subjects. TAAR1 drug amphetamine 26302754 In vitro analysis of HIV 1 infection of human PBMCs revealed increased TAAR1 expression in the presence of methamphetamine. TAAR1 drug amphetamine 26302754 In summary, the ability of methamphetamine to activate trace TAAR1 in vitro and to regulate important T cell functions, such as cAMP activation and IL 2 production; the expression of TAAR1 in T lymphocytes in peripheral lymphoid organs, such as lymph nodes; and our in vitro HIV 1 infection model in PBMCs suggests that TAAR1 may play an important role in methamphetamine mediated immune modulatory responses.

TAAR1 addiction aversion 25740289 The functional Taar1 allele, derived from the other founder strain, C57BL/6J, segregates with low MA drinking and heightened sensitivity to MA induced CTA and hypothermia. TAAR1 addiction aversion 25740289 A role for TAAR1 in these phenotypes is corroborated in Taar1 transgenic mice: Taar1 knockout mice consume more MA and exhibit insensitivity to MA induced CTA and hypothermia, compared with Taar1 wild type mice. TAAR1 addiction aversion 25740289 Behavioral and physiological studies indicate that TAAR1 function increases sensitivity to aversive effects of MA, and may thereby protect against MA use.

TAAR1 drug amphetamine 19364908 Trace amine associated receptor 1 (TAAR1) is expressed in brain dopaminergic nuclei and is activated by methamphetamine in vitro. TAAR1 drug amphetamine 19364908 Here, we show that methamphetamine interaction with TAAR1 inhibits [(3)H]dopamine uptake, enhances or induces [(3)H]dopamine efflux, and triggers DAT internalization. TAAR1 drug amphetamine 19364908 In time course assays in which methamphetamine and [(3)H]dopamine were concurrently loaded into cells or synaptosomes or in pretreatment assays in which methamphetamine was washed away before [(3)H]dopamine loading, methamphetamine caused a distinct inhibition in [(3)H]dopamine uptake in TAAR1 + DAT cotransfected cells and in wild type mouse and rhesus monkey striatal synaptosomes.

SIGMAR1 drug cocaine 32124388 The molecular mechanism involved in the acute cocaine induced increase in the antagonistic allosteric A2AR D2R receptor receptor interactions may be an increased formation of higher order complexes A2AR D2R sigma1R in which cocaine by binding to the sigma1R protomer also allosterically enhances the inhibitory A2AR D2R interaction in this receptor complex. SIGMAR1 drug cocaine 31782100 OSU 6162, a Sigma1R Ligand in Low Doses, Can Further Increase the Effects of Cocaine Self Administration on Accumbal D2R Heteroreceptor Complexes. SIGMAR1 drug cocaine 31782100 Cocaine was previously shown to act at the Sigma1R which is a target for counteracting cocaine actions.

SIGMAR1 drug cocaine 31782100 In contrast, in maintenance of cocaine self administration, the proximity ligation assay performed on brains from rats pretreated with OSU 6162 showed highly significant increases in the density of the D2R Sigma1R heteroreceptor complexes in the shell of the nucleus accumbens versus OSU 6162 induced increases in this region of yoked saline rats. SIGMAR1 drug cocaine 31782100 The current results indicate that OSU 6162 via its high affinity for the Sigma1R may increase the number of accumbal shell D2R Sigma1R and A2AR D2R heteroreceptor complexes associated with further increases in the antagonistic A2AR D2R interactions in cocaine self administration. SIGMAR1 drug cocaine 31596232 In NG108 cells and mouse midbrain tissue, we find that 2 AG is localized in non synaptic extracellular vesicles (EVs) that are secreted in the presence of cocaine via interaction with the chaperone protein sigma 1 receptor (Sig 1R). SIGMAR1 drug cocaine 31596232 The release of EVs occurs when cocaine causes dissociation of the Sig 1R from ADP ribosylation factor (ARF6), a G protein regulating EV trafficking, leading to activation of myosin light chain kinase (MLCK).

SIGMAR1 drug psychedelics 29674970 N,N Dimethyltryptamine (DMT, one of the alkaloids in Ayahuasca) activates sigma 1 receptor (SIGMAR1) and others. SIGMAR1 drug psychedelics 29674970 Since traumatic memories in post traumatic stress disorder (PTSD) are often characterised by "repression" and PTSD patients ingesting Ayahuasca report the retrieval of such memories, it cannot be excluded that DMT mediated SIGMAR1 activation and the concomitant MAOIs effects during Ayahuasca ingestion might mediate such "anti amnesic" process. SIGMAR1 drug psychedelics 29674970 Here I hypothesise that Ayahuasca, via hyperactivation of trauma and emotional memory related centres, and via its concomitant SIGMAR1 and MAOIs induced anti amnesic effects, facilitates the retrieval of traumatic memories, in turn making them labile (destabilised). SIGMAR1 addiction addiction 29674970 Lastly, since SIGMAR1 activation triggers both epigenetic and immunomodulatory programmes, the mechanism here presented could help understanding and treating other conditions in which the cellular memory is dysregulated, such as cancer, diabetes, autoimmune and neurodegenerative pathologies and substance addiction. SIGMAR1 drug alcohol 29205397 Alcohol drinking also reduced the striatal density of D2R D2R homoreceptor complexes, increased the density of A2AR D2R heteroreceptor complexes in the NAc shell and the dorsal striatum, and decreased the density of sigma1R D2R heteroreceptor complexes in the dorsal striatum.

SIGMAR1 drug cocaine 28300546 The results suggest that cocaine self administration can reorganize A2AR and D2R into increased A2AR D2R heteroreceptor complexes in the nucleus accumbens shell associated with increases in the D2R sigma1R heteroreceptor complexes in this region. SIGMAR1 drug cocaine 28300546 This reorganization can contribute to the demonstrated anti cocaine actions of A2A receptor agonists and the putative formation of A2AR D2R sigma1R heterocomplexes.

SIGMAR1 drug psychedelics 26973523 A growing number of studies indicate that the psychotherapeutic potential of ayahuasca is based mostly on the strong serotonergic effects, whereas the sigma 1 receptor (Sig 1R) agonist effect of its active ingredient dimethyltryptamine raises the possibility that the ethnomedical observations on the diversity of treated conditions can be scientifically verified. SIGMAR1 drug psychedelics 26973523 This article has two important take home messages: (1) the therapeutic effects of ayahuasca are best understood from a bio psycho socio spiritual model, and (2) on the biological level ayahuasca may act against chronic low grade inflammation and oxidative stress via the Sig 1R which can explain its widespread therapeutic indications.

SIGMAR1 drug alcohol 25848705 Administration of the selective Sig 1R antagonist BD 1063 dramatically reduced the acquisition of alcohol drinking behavior as well as the preference for alcohol in genetically selected TSRI Sardinian alcohol preferring (Scr:sP) rats; the treatment had instead no effect on total fluid intake, food intake or body weight gain, proving selectivity of action. SIGMAR1 drug alcohol 25848705 Finally, an innate elevation in Sig 1R protein levels was found in the nucleus accumbens of alcohol preferring Scr:sP rats, compared to outbred Wistar rats, alteration which was normalized by chronic, voluntary alcohol drinking. SIGMAR1 drug alcohol 25848705 Taken together these findings demonstrate that Sig 1R blockade reduces the propensity to both acquire alcohol drinking and to seek alcohol, and point to the nucleus accumbens as a potential key region for the effects observed.

NPFF drug opioid 1800944 Previously, NPFF precipitated opiate abstinence syndrome, while IgG from NPFF antiserum attenuated subsequent naloxone precipitated abstinence signs in dependent rats. NPFF drug opioid 1800944 Pretreatment with 600 ng of NPFF itself, or of NPFF modified at the N terminal only (daY9Fa), failed to attenuate subsequent naloxone precipitated abstinence, suggesting that the C terminal modification is critical for NPFF antagonist activity.

HOMER2 addiction reward 32116834 Transgenic Analyses of Homer2 Function Within Nucleus Accumbens Subregions in the Regulation of Methamphetamine Reward and Reinforcement in Mice. HOMER2 addiction reward 32116834 Recently, we discovered an association between genetic vulnerability to MA taking and increased expression of the glutamate receptor scaffolding protein Homer2 within both the shell and core subregions of the nucleus accumbens (NAC) and demonstrated a necessary role for Homer2 within the shell subregion in MA reward and reinforcement in mice. HOMER2 addiction reward 32116834 This report extends our earlier work by interrogating the functional relevance of Homer2 within the NAC core for the conditioned rewarding and reinforcing properties of MA. HOMER2 addiction reward 32116834 To determine whether Homer2b within NAC subregions played an active role in regulating MA reward and reinforcement, we characterized the MA phenotype of constitutive Homer2 knockout (KO) mice and then assayed the effects of virus mediated overexpression of Homer2b within the NAC shell and core of wild type and KO mice.

HOMER2 drug alcohol 29249995 Homer2 and Alcohol: A Mutual Interaction. HOMER2 drug alcohol 29249995 The consequences of repeated alcohol administration on the expression of the Homer family proteins demonstrate a crucial and active role, particularly for the expression of Homer2 isoform, in regulating alcohol induced behavioral and cellular neuroplasticity. HOMER2 drug alcohol 29249995 The interaction between Homer2 and alcohol can be defined as a mutual relation: alcohol consumption enhances the expression of Homer2 protein isoform within the nucleus accumbens and the extended amygdala, cerebral areas where, in turn, Homer2 is able to mediate the development of the "pro alcoholic" behavioral phenotype, as a consequence of the morpho functional synaptic adaptations. HOMER2 addiction addiction 29234834 One day after the final self administration session, the rats were euthanized and the dmPFC was removed for quantification of mRNA expression of critical glutamatergic signaling genes, Homer2, Grin1, and Dlg4, as these genes and brain region have been previously implicated in addiction, learning, and memory.

HOMER2 addiction intoxication 29109058 A history of binge drinking decreases protein expression of the glutamate related scaffolding protein Homer2 within the central nucleus of the amygdala (CEA), coinciding with behavioral signs of negative affect. HOMER2 addiction withdrawal 29109058 To assess the functional relevance of this protein change for withdrawal induced hyper anxiety, adult (PND 56) and adolescent (PND 28) male C57BL/6J mice were administered an intra CEA infusion of an adeno associated viral vector (AAV) carrying either cDNA to express Homer2 (H2 cDNA) or GFP as control. HOMER2 drug alcohol 29109058 Following behavioral testing, all animals experienced 5 days of drinking to evaluate the effects of prior alcohol experience and Homer2 manipulation on subsequent alcohol consumption. HOMER2 drug alcohol 29109058 Homer2 cDNA infusion in adolescent onset alcohol drinking animals was anxiolytic and reduced subsequent alcohol consumption. HOMER2 addiction intoxication 29109058 Nevertheless, the present results provide novel cause effect evidence supporting a role for CEA Homer2 in the regulation of both basal anxiety and the time dependent intensification of negative affective states in individuals with a history of binge drinking during adolescence. HOMER2 addiction aversion 27890469 Neuropharmacological and Homer2 knockdown approaches were also used in C57BL/6J mice to confirm the role for nucleus accumbens (NAC) glutamate/Homer2 expression in MA preference/aversion. HOMER2 addiction withdrawal 27890469 We also confirmed that subchronic subtoxic MA experience elicits a hyperglutamatergic state within the NAC during protracted withdrawal, characterized by elevated metabotropic glutamate 1/5 receptor function and Homer2 receptor scaffolding protein expression. HOMER2 drug alcohol 26773198 Expression of genes encoding mGlu1, mGlu5, the NR2A subunit of the NMDA receptor, and Homer2 were all decreased by binge alcohol consumption in males, while females were relatively resistant (only phosphoinositide dependent protein kinase 1 was decreased).

HOMER2 drug alcohol 26426435 Thus, Homer2 deletion may perturb the function or acute ethanol sensitivity of the NMDA receptor. HOMER2 drug alcohol 26426435 In this study, the function and ethanol sensitivity of glutamate receptors in cultured hippocampal neurons from wild type (WT) and Homer2 knock out (KO) mice were examined at 7 and 14 days in vitro (DIV) using standard whole cell voltage clamp electrophysiology.

HOMER2 drug alcohol 26254965 In murine models of alcoholism, the glutamate receptor scaffolding protein Homer2 bidirectionally regulates alcohol intake. HOMER2 drug alcohol 26254965 Although chronic alcohol drinking increases Homer2 expression within the core subregion of the nucleus accumbens (NAc) of alcohol preferring P rats, the relevance of this neuroadaptation for alcohol intake has yet to be determined in rats. HOMER2 drug alcohol 26254965 No net flux in vivo microdialysis was conducted for glutamate in the NAc to relate Homer2 dependent changes in alcohol intake to extracellular levels of glutamate. HOMER2 drug alcohol 26101849 Importantly, the association between several genetic variants within the mGluR eEF2 AMPAR pathway and alcohol use behavior (i.e., consumption and alcohol related problems) replicated in the Grady Trauma Project (GTP), an independent sample of adults living in Atlanta, Georgia (n = 1034; 95% African American), including individual variants in GRM1, GRM5, EEF2, MTOR, GRIA1, GRIA4 and HOMER2 (P < 0.05).

HOMER2 drug alcohol 25755642 Homer2 deletion alters dendritic spine morphology but not alcohol associated adaptations in GluN2B containing N methyl D aspartate receptors in the nucleus accumbens. HOMER2 drug alcohol 25755642 Homer2 is a member of a family of postsynaptic density (PSD) scaffolding proteins that functions in part to cluster N methyl D aspartate (NMDA) signaling complexes in the PSD, and has been shown to be critically important for plasticity in multiple models of drug and alcohol abuse. HOMER2 drug alcohol 25755642 Here we used Homer2 knockout (KO) mice and a chronic intermittent intraperitoneal (IP) ethanol injection model to investigate a potential role for the protein in ethanol induced adaptations in dendritic spine morphology and PSD protein expression. HOMER2 drug alcohol 25755642 While deletion of Homer2 was associated with increased density of long spines on medium spiny neurons of the NAc core of saline treated mice, ethanol exposure had no effect on dendritic spine morphology in either wild type (WT) or Homer2 KO mice.

HOMER2 drug cocaine 24118426 Behavioral studies employed adeno associated virus (AAV) vectors to reverse cocaine elicited changes in the relative expression of Homer1 versus Homer2 isoforms and tested animals for cocaine prime , and cue induced responding following extinction training. HOMER2 drug cocaine 24118426 Reversing the relative increase in Homer2 versus Homer1 expression via Homer1c overexpression or Homer2b knockdown failed to influence cue reinforced lever pressing when animals were tested in a drug free state, but both AAV treatments prevented cocaine primed reinstatement of lever pressing behavior.

HOMER2 drug cocaine 24118426 These data suggest that a cocaine elicited imbalance in the relative expression of constitutively expressed Homer2 versus Homer1 within the vmPFC is necessary for the capacity of cocaine to reinstate drug seeking behavior, posing drug induced changes in vmPFC Homer expression as a molecular trigger contributing to drug elicited relapse.

HOMER2 drug alcohol 22432643 Alcohol increases the expression of Group 1 metabotropic glutamate receptors (mGluRs) and their associated scaffolding protein Homer2 and stimulates phosphatidylinositol 3 kinase (PI3K) within the nucleus accumbens (NAC). HOMER2 drug alcohol 22432643 Moreover, functional studies suggest that NAC Group 1 mGluR/Homer2/PI3K signaling may be a potential target for pharmacotherapeutic intervention in alcoholism. HOMER2 drug alcohol 22432643 Follow up behavioral studies examined the importance of Group 1 mGluR/Homer2/PI3K signaling within the NAC shell for limited access alcohol drinking. HOMER2 drug alcohol 22432643 Limited access alcohol drinking under DID procedures up regulated NAC shell Homer2 levels, concomitant with increases in mGluR5 and NR2B. HOMER2 drug alcohol 22432643 Intra NAC shell blockade of mGluR5, Homer2, or PI3K signaling, as well as transgenic disruption of the Homer binding site on mGluR5, decreased alcohol consumption in B6 mice. HOMER2 drug alcohol 22432643 Taken together, these data further implicate Group 1 mGluR signaling through Homer2 within the NAC in excessive alcohol consumption.

HOMER2 drug alcohol 20807241 These data support the over arching hypothesis that augmented accumbens Homer2 mediated glutamate signaling may be an endophenotype related to genetic variance in alcohol consumption. HOMER2 drug alcohol 20807241 If relevant to humans, such data pose polymorphisms affecting glutamate receptor/Homer2 signaling in the etiology of alcoholism. HOMER2 drug alcohol 20333726 Five genetic variants of HOMER 1 and 3 of HOMER 2 were genotyped in a multi site sample of 1,923 German healthy controls and 2,039 alcohol dependent subjects. HOMER2 drug alcohol 20333726 While most of the HOMER 1 and 2 SNPs are in low to moderate linkage disequilibrium, three major haplotypes of HOMER 1 and 4 haplotypes of HOMER 2 are present in the majority of alcohol dependent and control subjects.

HOMER2 drug alcohol 19587272 Finally, mice genetically selected for a high versus low SHAC phenotype differed in NAC mGluR, Homer2, and PI3K activity, consistent with the hypothesis that augmented NAC mGluR5 Homer2 PI3K signaling predisposes a high binge alcohol drinking phenotype.

HOMER2 drug alcohol 16049182 Constitutive Homer2 gene deletion [knock out (KO)] and rescue with adeno associated viral (AAV) transfection of Homer2b was used to demonstrate the importance of Homer proteins in neuroplasticity produced by repeated ethanol (EtOH) administration. HOMER2 addiction sensitization 16049182 Homer2 KO mice avoided drinking high concentrations of EtOH and did not develop place preference or locomotor sensitization after repeated EtOH administration. HOMER2 drug cocaine 15580483 To evaluate the hypothesis that repeated intra VTA microinjections of the ionotropic glutamate agonist, AMPA, or the metabotropic glutamate agonist, t ACPD, augment the behavioral hyperactivity induced by a subsequent challenge injection of cocaine. HOMER2 drug cocaine 15580483 Following the cocaine challenge injection, there was an augmentation of cocaine induced behavioral hyperactivity in the groups pretreated with AMPA or t ACPD but not in the animals administered t ACPD plus KN 93. HOMER2 drug cocaine 15545022 Homer2 gene deletion in mice produces a phenotype similar to chronic cocaine treated rats. HOMER2 drug cocaine 15545022 In this report we summarize the behavioral and neurochemical effects of Homer2 gene deletion in mice and compare this with the effects of chronic cocaine treatment in rats. HOMER2 drug cocaine 15545022 It was shown that Homer2 KO mice demonstrate enhanced locomotor stimulant and conditioned place preference responses to cocaine. HOMER2 drug cocaine 15545022 Homer2 deletion also caused mice to show reduced basal extracellular glutamate in the nucleus accumbens and a sensitized increase in extracellular glutamate in response to a cocaine injection. HOMER2 drug cocaine 15545022 In contrast to glutamate, Homer2 KO mice showed a normal increase in extracellular dopamine following a cocaine challenge injection. HOMER2 drug cocaine 15545022 The parallel between the effect of Homer2 gene deletion and chronic cocaine administration on behavioral and glutamatergic neurochemical responses to cocaine supports involvement of Homer proteins and glutamate transmission in the sensitization of behavior produced by repeated cocaine.

HOMER2 drug alcohol 12500101 Acamprosate inhibits the binding and neurotoxic effects of trans ACPD, suggesting a novel site of action at metabotropic glutamate receptors. HOMER2 drug alcohol 12500101 The following experiments were performed to determine whether acamprosate could compete with trnas ACPD (+/ 1 aminocyclopentane trans 1,3 dicarboxylic acid, an equimolecular mixture of 1S, 3R and 1R, 3S ACPD and an agonist at both group I and group II mGluRs) sensitive binding sites and protect against trans ACPD induced neurotoxicity in organotypic hippocampal slice cultures. HOMER2 drug alcohol 12500101 A P2 membrane preparation of cortices, cerebellums, and hippocampi of adult, male Sprague Dawley rats was used to determine the abilities of N methyl D aspartic acid (NMDA) and trans ACPD to displace [3H]glutamate in both the absence and the presence of the sodium salt of acamprosate (sodium mono N acetyl homotaurine or Na acamprosate). HOMER2 drug alcohol 12500101 A comparison of the effects of 100 microM guanosine 5' triphosphate on unlabeled glutamate, trans ACPD, and Na acamprosate was performed in the same paradigm. HOMER2 drug alcohol 12500101 Na acamprosate displayed total competition with trans ACPD. HOMER2 drug alcohol 12500101 The presence of 100 microM guanosine 5' triphosphate differentially altered the displacing capabilities of the two mGluR agonists, unlabeled glutamate and trans ACPD, as compared with Na acamprosate. HOMER2 drug alcohol 12500101 Na acamprosate (200 1000 microM) and SIB 1893 (20 500 microM) both were neuroprotective against trans ACPD induced neurotoxicity that likely results from mGluR potentiation of NMDARs.

HOMER2 drug amphetamine 9152375 Current response curves showed that responses to iontophoretic AMPA, but not NMDA or 1S,3R t ACPD were significantly enhanced in cocaine or amphetamine pretreated rats in that neurons entered into a state of apparent depolarization block at significantly lower iontophoretic currents. HOMER2 drug cocaine 9152375 Current response curves showed that responses to iontophoretic AMPA, but not NMDA or 1S,3R t ACPD were significantly enhanced in cocaine or amphetamine pretreated rats in that neurons entered into a state of apparent depolarization block at significantly lower iontophoretic currents. HOMER2 addiction withdrawal 9127819 After a 6 day withdrawal, DA release from striatal slices evoked by +/ ( )1 aminocyclopentane trans 1,3 dicarboxylic acid (trans ACPD) was measured, trans ACPD induced DA release was significantly enhanced in MAP sensitized rats, but the inactive form of trans ACPD (1R,3S ACPD) did not enhance DA release. HOMER2 drug benzodiazepine 7616393 Dose response curves for stimulation of phosphoinositide (PI) hydrolysis by the selective metabotropic glutamate receptor (mGluR) agonist, (1S,3R) 1 aminocyclopentane dicarboxylic acid [(1S,3R) ACPD] were performed with cortical slices from mice treated with lorazepam or vehicle for 7 days and subject to 0, 1, 2, 3, 4 and 7 days of withdrawal. HOMER2 addiction withdrawal 7616393 Dose response curves for stimulation of phosphoinositide (PI) hydrolysis by the selective metabotropic glutamate receptor (mGluR) agonist, (1S,3R) 1 aminocyclopentane dicarboxylic acid [(1S,3R) ACPD] were performed with cortical slices from mice treated with lorazepam or vehicle for 7 days and subject to 0, 1, 2, 3, 4 and 7 days of withdrawal. HOMER2 drug benzodiazepine 7616393 The efficacy of (1S,3R) ACPD to stimulate PI hydrolysis was increased significantly at 2 and 3 days of lorazepam withdrawal when compared with responses in control slices. HOMER2 addiction withdrawal 7616393 The efficacy of (1S,3R) ACPD to stimulate PI hydrolysis was increased significantly at 2 and 3 days of lorazepam withdrawal when compared with responses in control slices. HOMER2 drug alcohol 7893331 Exposure in utero to ethanol did not affect PPI hydrolysis stimulated by a selective metabotropic glutamate receptor agonist, trans (+/ ) l amino 1,3 cyclopentanedicarboxylic acid (t ACPD). HOMER2 drug alcohol 7893331 Although the PPI hydrolysis stimulated by t ACPD could be blocked by (RS) alpha methyl 4 carboxyphenylglycine (MCPG), an antagonist of the metabotropic glutamate receptor, MCPG was incapable of affecting QA induced PPI hydrolysis and the suppressive effects of prenatal ethanol exposure on this hydrolysis. HOMER2 drug alcohol 7893331 Taken together, the data suggest that the long lasting suppressive effects of prenatal ethanol exposure on QA stimulated PPI hydrolysis in cerebellar granule cell cultures is through a metabotropic QA receptor pathway that may be different from the one activated by t ACPD.

GNRH1 drug cannabinoid 27354844 Evidence suggests that marijuana can reduce female fertility by disrupting hypothalamic release of gonadotropin releasing hormone (GnRH), leading to reduced estrogen and progesterone production and anovulatory menstrual cycles. GNRH1 drug opioid 22183092 Search from databases Pubmed, SciFinder, and Medline with search words opioid antagonists, hormones, LH, testosterone, and GnRH, in different combinations. GNRH1 drug opioid 22183092 Opioid antagonists seem to increase the secretion of GnRH in the hypothalamus which then causes a pulsatile release of LH in the pituitary and secretion of testosterone. GNRH1 drug alcohol 20034543 Since alcohol (ALC) blocks IGF 1 induced LHRH release acutely, we assessed whether this drug could affect IGF 1 stimulated prepubertal KiSS 1 gene expression following a binge type of exposure. GNRH1 addiction intoxication 20034543 Since alcohol (ALC) blocks IGF 1 induced LHRH release acutely, we assessed whether this drug could affect IGF 1 stimulated prepubertal KiSS 1 gene expression following a binge type of exposure. GNRH1 drug alcohol 18448097 Ethanol is known to reduce hypothalamic synthesis, release, and mRNA expression of gonadotropin releasing hormone (GnRH) that modulates serotonergic, dopaminergic, and glutamatergic systems, which experience adaptive changes on chronic exposure to ethanol. GNRH1 drug alcohol 18448097 Therefore, it was proposed to investigate the effect of ethanol withdrawal on marble burying behavior in mice, particularly because it simulates some aspects of obsessive compulsive behavior; further, the influence of GnRH agonist was studied on the same.

GNRH1 drug psychedelics 18309234 Here, we hypothesized that the recreational drug (+/ ) 3,4 methylenedioxymethamphetamine (MDMA; 'ecstasy'), which acts through several of the neurotransmitter systems that affect GnRH neurons, suppresses the hypothalamic pituitary gonadal reproductive axis of male rats. GNRH1 drug psychedelics 18309234 The results indicate that the hypothalamic and gonadal levels of the hypothalamic pituitary gonadal axis are significantly altered by MDMA, with GnRH mRNA and serum testosterone levels suppressed in rats administered MDMA compared to saline. GNRH1 drug psychedelics 18309234 Furthermore, our finding that hypothalamic GnRH mRNA levels are suppressed in the context of low testosterone concentrations suggests that the central GnRH neurosecretory system may be a primary target of inhibitory regulation by MDMA usage. GNRH1 drug alcohol 18280564 Ethanol inhibits the synthesis, content and release of hypothalamic luteinizing hormone releasing hormone (LHRH), and LHRH modulates the activity of several neurotransmitters that experience adaptive changes on chronic exposure to ethanol, and also implicate in ethanol dependence. GNRH1 addiction dependence 18280564 Ethanol inhibits the synthesis, content and release of hypothalamic luteinizing hormone releasing hormone (LHRH), and LHRH modulates the activity of several neurotransmitters that experience adaptive changes on chronic exposure to ethanol, and also implicate in ethanol dependence. GNRH1 drug alcohol 18280564 Hence, it was contemplated that LHRH agonist such as leuprolide may influence the behavioral consequences of withdrawing ethanol in dependent state. GNRH1 addiction withdrawal 10818386 Puberty results from withdrawal of the "gonadostat" mechanisms and from increased gonadotropin sensitivity to GnRH. GNRH1 drug opioid 10818386 Neuropeptides mainly involved in the control of GnRH release are opioids, neuropeptide Y (NPY), galanin, and corticotropin releasing factor (CRF), whereas neurotransmitters are noradrenaline, dopamine, serotonin, melatonin and gamma aminobutyric acid (GABA). GNRH1 drug alcohol 9037095 Inhibition of the PLD pathway by ethanol and propranolol reduced diacylglycerol production and caused a concomitant fall in GnRH release. GNRH1 addiction withdrawal 9014843 Concentration of GnRH receptor and GnRH receptor mRNA in pituitary tissue of orchidectomized sheep: effect of oestradiol, progesterone, and progesterone withdrawal. GNRH1 addiction withdrawal 9014843 The effect of progesterone (P4) and P4 withdrawal on oestradiol (E2) induced change in gonadotrope responsiveness (GR) and concentration of GnRH receptor and GnRH receptor mRNA in pituitary tissue of orchidectomized sheep (wethers) was determined. GNRH1 addiction withdrawal 9014843 This P4 induced decrease in tissue concentration of GnRH receptor and GnRH receptor mRNA was not reversed during the 24 h period after P4 withdrawal. GNRH1 addiction withdrawal 9014843 However, the magnitude of oestrogen induced increase in tissue concentrations of GnRH receptor mRNA was not significantly affected by P4 or P4 withdrawal. GNRH1 addiction withdrawal 9014843 This P4 induced suppression of GnRH receptor activity is not reversed within 24 h of P4 withdrawal. GNRH1 drug opioid 8828858 However, our observation that Nmf accelerated the reinstatement of ovarian cycles after surgery, when circulating E2 and P4 were very low, suggests that GnRH secretions are influenced by activation of different opioid receptor subtypes in response to different stresses. GNRH1 addiction relapse 8828858 However, our observation that Nmf accelerated the reinstatement of ovarian cycles after surgery, when circulating E2 and P4 were very low, suggests that GnRH secretions are influenced by activation of different opioid receptor subtypes in response to different stresses. GNRH1 drug opioid 8828858 Some of these GnRH/opioid interactions are independent of P4. GNRH1 addiction withdrawal 8788193 The effects of estradiol (E2) and E2 withdrawal on tissue concentrations of GnRH receptor mRNA were assessed in orchidectomized sheep (wethers). GNRH1 addiction withdrawal 8788193 These data suggest that the dynamic changes in tissue concentrations of GnRH receptor mRNA during the periovulatory period may be due to the inductive effects of gonadal steroids from the developing follicle and to the combined suppressive effects of the increased GnRH stimulation and E2 withdrawal that are associated with the gonadotropin surge. GNRH1 drug alcohol 7579706 Also, phospholipase D activity, estimated by the production of phosphatidylethanol from phosphatidylcholine in the presence of ethanol, was stimulated by GnRH but not ET 1. GNRH1 drug alcohol 7579706 Inhibition of PA phosphohydrolase activity by propranolol also decreased GnRH induced DG production and, in contrast to ethanol, increased PA and cytidine diphosphate diacylglycerol levels. GNRH1 drug alcohol 7579706 The fall in DG production caused by ethanol and propranolol was accompanied by inhibition of GnRH induced c fos expression, whereas agonist induced luteinizing hormone release was not affected. GNRH1 drug alcohol 7579706 In contrast to their inhibitory actions on GnRH induced early gene expression, neither ethanol nor propranolol affected ET 1 induced c fos expression, or GnRH and ET 1 induced inositol trisphosphate/Ca2+ signaling. GNRH1 drug alcohol 7883843 In each subject, LH pulsatility (10 min blood drawing for 8 h) and the pituitary LH response to a 10 micrograms GnRH stimulus were investigated at baseline and on the fifth day of placebo/naltrexone administration. GNRH1 drug alcohol 7883843 The same occurred after naltrexone treatment, when significant increases in both mean LH levels (P < 0.02) and LH response to GnRH (P < 0.025) were observed. GNRH1 drug alcohol 7883843 The same occurred after naltrexone treatment, when significant decreases in both the amplitude of LH pulses (P < 0.05) and the LH response to GnRH (P < 0.05) were observed. GNRH1 drug opioid 7852517 Short term naloxone infusion studies have suggested that enhanced endogenous opioid activity may play a role in inhibiting GnRH and gonadotropin secretion in hyperprolactinemic patients. GNRH1 drug opioid 7956937 The aim of the present study was, using an in vitro superfusion approach, to perform a detailed study of the effects of opioid receptor activation and blockade on the dimensions of pulsatile GnRH release from the isolated medial basal hypothalamus of the adult male guinea pig. GNRH1 drug opioid 7956937 Morphine suppressed total GnRH output from the medial basal hypothalami (P < or = 0.01 at 10( 3) M and 10( 6) M; P = NS at 10( 9) M), with mean pulse frequency, mean amplitude of all pulses, and mean sum of pulse amplitudes being significantly inhibited at all morphine concentrations, whether pulse analysis (Ultra pulse analysis algorithm) was performed at a two coefficient of variation (2CV; P < or = 0.05, P < or = 0.01, and P < or = 0.01, respectively) or a 3CV (P < or = 0.05, P < or = 0.05, and P < or = 0.01, respectively) threshold. GNRH1 drug opioid 7956937 A different set of experiments (n = 14), with exposure to 10( 3) M morphine during the second of three consecutive 3 h observation periods, indicated that after morphine withdrawal a gradual recovery of GnRH output and pulse frequency to pretreatment values occurred, whereas pulse amplitude remained significantly suppressed during the posttreatment observation period. GNRH1 addiction withdrawal 7956937 A different set of experiments (n = 14), with exposure to 10( 3) M morphine during the second of three consecutive 3 h observation periods, indicated that after morphine withdrawal a gradual recovery of GnRH output and pulse frequency to pretreatment values occurred, whereas pulse amplitude remained significantly suppressed during the posttreatment observation period. GNRH1 drug opioid 7956937 Total GnRH output (P < or = 0.05), mean pulse frequency (P < or = 0.05), mean amplitude of all pulses (P < or = 0.05), and mean of the sum of pulse amplitudes (P < or = 0.01) were increased during opioid blockade with 10( 3) M and 10( 9) M naloxone (either 2CV or 3CV threshold for pulse analysis). GNRH1 drug opioid 7956937 A similar trend for 10( 6) M naloxone was only apparent after the exclusion of two outliers with unusually high basal GnRH release. GNRH1 drug opioid 7926138 The mode of action of the drug in GnRH a treated patients and possible interactions with endogenous opioid peptides need further elucidation. GNRH1 drug alcohol 8119185 However, the ability of GnRH to stimulate phosphatidylethanol (PEt) in the presence of ethanol suggested that phospholipase D may also participate in DG formation. GNRH1 drug alcohol 8286567 The magnitude of GnRH induced (1600 ng/hourly pulse for 24 h) preovulatory surge like secretion of LH was assessed in orchidectomized sheep (wethers) during infusion of estradiol (E2, 5 micrograms/h in 10% ethanol saline [vehicle]) or at 0, 12, 24, or 48 h after E2 withdrawal (n = 6 wethers/group). GNRH1 addiction withdrawal 8286567 The magnitude of GnRH induced (1600 ng/hourly pulse for 24 h) preovulatory surge like secretion of LH was assessed in orchidectomized sheep (wethers) during infusion of estradiol (E2, 5 micrograms/h in 10% ethanol saline [vehicle]) or at 0, 12, 24, or 48 h after E2 withdrawal (n = 6 wethers/group). GNRH1 drug opioid 1359599 Because hypothalamic opioids are believed to modulate GnRH secretion, in part under the influence of ovarian steroids, we performed longitudinal studies of gonadotropin and ovarian steroid secretion across ovulatory, symptomatic cycles of 17 PMS patients and 8 normal volunteers. GNRH1 drug alcohol 2508387 The cells of chambers I + II had been pretreated with medium containing vehicle (0.1% ethanol), those of chambers III + IV with medium containing 1 nmol/l estradiol for 48 h. After perfusion was started, each of the chambers was challenged with an initial 2 min GnRH (1 nmol/l) pulse.

GNRH1 drug opioid 2643703 In contrast to these results, adult rats showed only transient effects (less than 1 week) of morphine on certain reproductive endocrine parameters (e.g., serum LH, testosterone and the weights of the seminal vesicles) and no effects on others (e.g., testes weights and hypothalamic LHRH). GNRH1 drug alcohol 3122772 In men, provocative tests of gonadotropin response to LHRH stimulation were normal during periods of intoxication and hangover, indicating that ethanol has no significant direct effect on LH secretion at the pituitary level.

GNRH1 drug opioid 3100869 Withdrawal of the gonadal steroids has been reported to cause a rapid loss of the tonic inhibitory control of the opiate system on LHRH secretion as revealed by a lack of response to naloxone. GNRH1 addiction withdrawal 3100869 Withdrawal of the gonadal steroids has been reported to cause a rapid loss of the tonic inhibitory control of the opiate system on LHRH secretion as revealed by a lack of response to naloxone. GNRH1 drug opioid 6769068 Since the response of the pituitary to nonspecific stimuli is considered an expression of hypothalamic dysfunction, indicating a disconnection between the central nervous system and the anterior pituitary, we thought it worthwhile to study the GH response to stimulation with thyrotropin releasing hormone (TRH) or gonadotropin releasing hormone (GnRH) in heroin addicts. GNRH1 drug opioid 569031 Normal basal and LHRH stimulated LH and FSH levels suggest that chronic heroin abuse depressed testicular function via the hypothalamus or higher centres. GNRH1 drug opioid 356791 Time course of effects of morphine on hypothalamic content of LHRH and serum testosterone and LH levels of morphine tolerant and nontolerant male rats. GNRH1 drug opioid 356791 Time course of the effects of morphine on the hypothalamic content of LHRH in both nontolerant and morphine tolerant male rats was investigated in relation to the temporal changes of serum testosterone and LH levels. GNRH1 drug opioid 356791 The hypothalamic LHRH content of the nontolerant rats was increased 8 hr after the administration of morphine (100 mg/kg) when serum testosterone levels were depressed. GNRH1 drug opioid 356791 The LHRH content of the tolerant rats was decreased during withdrawal of morphine for 48 hr when the lowered serum testosterone and LH levels had returned to within the control levels. GNRH1 addiction withdrawal 356791 The LHRH content of the tolerant rats was decreased during withdrawal of morphine for 48 hr when the lowered serum testosterone and LH levels had returned to within the control levels. GNRH1 drug opioid 356791 Although the hypothalamic LHRH content does not necessarily reflect the release of LHRH, these results are in favour of the hypothesis that the release of hypothalamic LHRH is inhibited by the administration of morphine and is restored by the withdrawal of the narcotic.

PTH drug amphetamine 26946780 Moreover, phosphorylated tyrosine hydroxylase serine40 (pTH Ser40) levels in the ventral tegmental area (VTA) were increased by methamphetamine. PTH drug amphetamine 26946780 The increment of pTH Ser40 levels in the VTA by methamphetamine was attenuated by RS504393, a selective CC chemokine receptor 2 (CCR2) antagonist, indicating that the increased CCL2 activates the brain reward system via CCR2 activation.

PTH addiction relapse 19187564 The PTH level, but not the vitamin D level, is an independent predictor of MS in treatment seeking morbidly obese Caucasian women and men. PTH drug alcohol 17855333 Serum insulin like growth factor 1 (IGF 1), interleukin (IL) 6, IL 8, IL 10, TNF alpha, PTH, estradiol, free testosterone, and corticosterone were measured in 36 alcoholics, ten of them cirrhotics, who also underwent brain CT, which recorded the presence of cortical atrophy or cerebellar atrophy, Evan's, Huckmann's, cella media, bicaudate, cortical atrophy, bifrontal, and ventricular indices, and diameter of the third ventricle; subjective nutritional assessment, midarm anthropometry, and evaluation of liver function.

PTH drug alcohol 17204460 Effects of parathyroid hormone (1 34) on tibia in an adult rat model for chronic alcohol abuse. PTH drug alcohol 17204460 The purpose of the present study was to determine whether PTH is effective in increasing bone formation and bone mass in a rat model for established osteopenia caused by chronic alcohol abuse. PTH drug alcohol 17204460 High dose PTH (80 microg/kg/day) was administered 5 days/week for 6 weeks to establish the differential efficacy of hormone therapy on bone formation in alcohol consuming and alcohol withdrawn rats. PTH drug alcohol 17204460 The effects of alcohol and PTH on cancellous and cortical bone mass, architecture and turnover were determined by densitometry and histomorphometry. PTH drug alcohol 17204460 PTH treatment increased bone mineral content and density, bone formation rates, cortical bone area, cancellous bone area and trabecular number and thickness, but several indices of bone formation were reduced in the presence of continued alcohol consumption. PTH drug alcohol 17204460 These results suggest that alcohol consumption, in addition to inducing bone loss, may reduce the efficacy of PTH therapy to reverse osteoporosis.

PTH drug alcohol 1308958 With this study, the authors investigated parathyroid hormone (PTH) behaviour in thirteen selected patients with alcohol abuse, free from any clinical or humoral sign of hepatopathy, and in ten healthy subjects as a control group. PTH drug alcohol 1308958 In alcohol abusers a significant reduction of plasmatic PTH, compared to normal calcium levels were found. PTH drug alcohol 1308958 A possible direct interaction effect between ethyl alcohol and PTH may be suggested, even if further studies are required. PTH drug alcohol 1609627 Our alcoholic patients presented with (1) decreased serum concentrations of bone gla protein (BGP), suggesting decreased bone formation; (2) increased urinary excretion of hydroxyproline, suggesting increased bone resorption; (3) increased renal threshold of phosphate excretion without modification of serum PTH concentration, suggesting a direct effect of ethanol on the renal handling of phosphate. PTH drug alcohol 1997837 In the women, serum parathyroid hormone levels decreased from 29.2 +/ 2.8 to 17.3 +/ 2.6 ng per liter two hours after the administration of alcohol was begun (P less than 0.001) and increased above base line values during the last four hours of the study period. PTH drug alcohol 1997837 This decline in the secretion of parathyroid hormone accounts at least in part for the transient hypocalcemia, hypercalciuria, and hypermagnesuria that follow alcohol ingestion.

PRKAB1 drug alcohol 22451512 Given the role of AMPK in the initiation of autophagy through the mammalian target of rapamycin complex 1 (mTORC1) and Unc51 like kinase (ULK1), this study was designed to examine the impact of AMPK deficiency on cardiac function and the mechanism involved with a focus on autophagy following an acute ethanol challenge. PRKAB1 drug alcohol 22451512 Wild type (WT) and transgenic mice overexpressing a kinase dead (KD) α2 isoform (K45R mutation) of AMPK were challenged with ethanol. PRKAB1 drug alcohol 22451512 Ethanol exposure triggered glucose intolerance and compromised cardiac contraction accompanied by increased phosphorylation of AMPK and ACC as well as autophagosome accumulation (increased LC3II and p62), the effects of which were attenuated or mitigated by AMPK deficiency or inhibition. PRKAB1 drug alcohol 22451512 Ethanol dampened and stimulated, respectively, the phosphorylation of mTOR and Raptor, the effects of which were abolished by AMPK deficiency. PRKAB1 drug alcohol 22451512 ULK1 phosphorylation at Ser(757) and Ser(777) was down regulated and up regulated, respectively, by ethanol, the effect of which was nullified by AMPK deficiency or inhibition.

PRKAB1 drug alcohol 20585647 This study was designed to examine the impact of cardiac specific overexpression of alcohol dehydrogenase (ADH) on ethanol induced change in cardiac contractile function, intracellular Ca(2+) homeostasis, insulin and AMP dependent kinase (AMPK) signaling. PRKAB1 drug alcohol 20585647 Ethanol exposure led to glucose intolerance, elevated plasma insulin, compromised cardiac contractile and intracellular Ca(2+) properties, downregulated protein phosphatase PP2A subunit and PPAR gamma, as well as phosphorylation of AMPK, ACC and LKB1, all of which except plasma insulin were overtly accentuated by ADH transgene. PRKAB1 drug alcohol 20585647 In addition, the AMPK inhibitor compound C (10 microM) abrogated acute ethanol exposure elicited cardiomyocyte mechanical dysfunction. PRKAB1 drug alcohol 20585647 In summary, these data suggest that the ADH transgene exacerbated acute ethanol toxicity induced myocardial contractile dysfunction, intracellular Ca(2+) mishandling and glucose intolerance, indicating a role of ADH in acute ethanol toxicity induced cardiac dysfunction possibly related to altered cellular fuel AMPK signaling cascade.

PRKAB1 drug alcohol 19942091 ALDH2 significantly attenuated ethanol induced decrease in Akt and AMPK stimulated phosphorylation of Foxo3 at Thr32 and Ser413, respectively. PRKAB1 drug alcohol 19942091 Our results suggest that ALDH2 is cardioprotective against acute ethanol toxicity, possibly through inhibition of protein phosphatases, leading to enhanced Akt and AMPK activation, and subsequently, inhibition of Foxo3, apoptosis, and mitochondrial dysfunction.

PRKAA2 drug alcohol 22451512 Wild type (WT) and transgenic mice overexpressing a kinase dead (KD) α2 isoform (K45R mutation) of AMPK were challenged with ethanol. PRKAA2 drug alcohol 22451512 Ethanol exposure triggered glucose intolerance and compromised cardiac contraction accompanied by increased phosphorylation of AMPK and ACC as well as autophagosome accumulation (increased LC3II and p62), the effects of which were attenuated or mitigated by AMPK deficiency or inhibition. PRKAA2 drug alcohol 22451512 Ethanol dampened and stimulated, respectively, the phosphorylation of mTOR and Raptor, the effects of which were abolished by AMPK deficiency. PRKAA2 drug alcohol 22451512 ULK1 phosphorylation at Ser(757) and Ser(777) was down regulated and up regulated, respectively, by ethanol, the effect of which was nullified by AMPK deficiency or inhibition.

PRKAA2 drug alcohol 20585647 Ethanol exposure led to glucose intolerance, elevated plasma insulin, compromised cardiac contractile and intracellular Ca(2+) properties, downregulated protein phosphatase PP2A subunit and PPAR gamma, as well as phosphorylation of AMPK, ACC and LKB1, all of which except plasma insulin were overtly accentuated by ADH transgene. PRKAA2 drug alcohol 20585647 In addition, the AMPK inhibitor compound C (10 microM) abrogated acute ethanol exposure elicited cardiomyocyte mechanical dysfunction. PRKAA2 drug alcohol 20585647 In summary, these data suggest that the ADH transgene exacerbated acute ethanol toxicity induced myocardial contractile dysfunction, intracellular Ca(2+) mishandling and glucose intolerance, indicating a role of ADH in acute ethanol toxicity induced cardiac dysfunction possibly related to altered cellular fuel AMPK signaling cascade.

PRKAA1 drug alcohol 31734306 The phosphorylation of TAK1, another upstream kinase of AMPK, was increased only from 30 min to 24 h after the chronic treatment with ethanol. PRKAA1 drug alcohol 31734306 This effect seems to be mediated by the AMPK system, and may contribute to the long lasting neuroadaptation involved in the development of alcohol dependence.

PRKAA1 drug cocaine 27132751 Region specific activation of the AMPK system by cocaine: The role of D1 and D2 receptors. PRKAA1 drug cocaine 27132751 Thus, the present study examined whether the sensitizing effects of cocaine could be observed in the AMPK system and aimed to determine whether these effects were mediated by dopamine (DA) D1 or D2 receptors. PRKAA1 drug cocaine 27132751 In the drug naïve state, acute treatment with cocaine produced an increase in locomotor activity and increased AMPK phosphorylation in the frontal cortex but decreased it in the dorsal striatum. PRKAA1 drug cocaine 27132751 In the drug sensitized state (following repeated treatment), the behavioral responsiveness to cocaine was augmented and accompanied by alterations in AMPK activity. PRKAA1 drug cocaine 27132751 The opposite effects induced by cocaine in the AMPK system in the dorsal striatum and frontal cortex may be explained by the differential activations of DA D1 and D2 receptors in these brain regions.

PRKAA1 drug alcohol 22451512 Deficiency in AMPK attenuates ethanol induced cardiac contractile dysfunction through inhibition of autophagosome formation. PRKAA1 addiction intoxication 22451512 Binge drinking often triggers compromised myocardial contractile function while activating AMP activated protein kinase (AMPK). PRKAA1 drug alcohol 22451512 Given the role of AMPK in the initiation of autophagy through the mammalian target of rapamycin complex 1 (mTORC1) and Unc51 like kinase (ULK1), this study was designed to examine the impact of AMPK deficiency on cardiac function and the mechanism involved with a focus on autophagy following an acute ethanol challenge. PRKAA1 drug alcohol 22451512 Wild type (WT) and transgenic mice overexpressing a kinase dead (KD) α2 isoform (K45R mutation) of AMPK were challenged with ethanol. PRKAA1 drug alcohol 22451512 Ethanol exposure triggered glucose intolerance and compromised cardiac contraction accompanied by increased phosphorylation of AMPK and ACC as well as autophagosome accumulation (increased LC3II and p62), the effects of which were attenuated or mitigated by AMPK deficiency or inhibition. PRKAA1 drug alcohol 22451512 Ethanol dampened and stimulated, respectively, the phosphorylation of mTOR and Raptor, the effects of which were abolished by AMPK deficiency. PRKAA1 drug alcohol 22451512 ULK1 phosphorylation at Ser(757) and Ser(777) was down regulated and up regulated, respectively, by ethanol, the effect of which was nullified by AMPK deficiency or inhibition. PRKAA1 drug alcohol 22451512 Moreover, the ethanol challenge enhanced LC3 puncta in H9c2 cells and promoted cardiac contractile dysfunction, and these effects were ablated by the inhibition of autophagy or AMPK. PRKAA1 drug alcohol 22451512 In summary, these data suggest that ethanol exposure may trigger myocardial dysfunction through a mechanism associated with AMPK mTORC1 ULK1 mediated autophagy. PRKAA1 drug nicotine 22315316 The aim of this study was to investigate the effect of nicotine on hypothalamic AMP activated protein kinase (AMPK) and its effect on energy balance.

PRKAA1 drug alcohol 22272351 In primary rat alveolar type II cells alcohol and adenosine decreased the abundance of the Na,K ATPase at the basolateral membrane via a mechanism that required activation of the AMPK. PRKAA1 drug alcohol 21062897 Moreover, activation of AMPK, a known positive modulator of sirtuin activity, prevented the ethanol induced suppression of sirtuin 3 activity and the attendant increase of cyclophilin D acetylation, activity and association with ANT 1. PRKAA1 drug alcohol 21062897 Additionally, AMPK reactivation of sirtuin 3 prevented the sensitization to the MPT and the enhancement of cell killing by TNF in cells exposed to ethanol.

PRKAA1 drug alcohol 20585647 Involvement of AMPK in alcohol dehydrogenase accentuated myocardial dysfunction following acute ethanol challenge in mice. PRKAA1 drug alcohol 20585647 This study was designed to examine the impact of cardiac specific overexpression of alcohol dehydrogenase (ADH) on ethanol induced change in cardiac contractile function, intracellular Ca(2+) homeostasis, insulin and AMP dependent kinase (AMPK) signaling. PRKAA1 drug alcohol 20585647 Ethanol exposure led to glucose intolerance, elevated plasma insulin, compromised cardiac contractile and intracellular Ca(2+) properties, downregulated protein phosphatase PP2A subunit and PPAR gamma, as well as phosphorylation of AMPK, ACC and LKB1, all of which except plasma insulin were overtly accentuated by ADH transgene. PRKAA1 drug alcohol 20585647 In addition, the AMPK inhibitor compound C (10 microM) abrogated acute ethanol exposure elicited cardiomyocyte mechanical dysfunction. PRKAA1 drug alcohol 20585647 In summary, these data suggest that the ADH transgene exacerbated acute ethanol toxicity induced myocardial contractile dysfunction, intracellular Ca(2+) mishandling and glucose intolerance, indicating a role of ADH in acute ethanol toxicity induced cardiac dysfunction possibly related to altered cellular fuel AMPK signaling cascade. PRKAA1 drug alcohol 19942091 Ethanol treatment dampened phosphorylation of Akt and AMPK associated with up regulated PP2A and PP2C, which was abrogated by ALDH2. PRKAA1 drug alcohol 19942091 ALDH2 significantly attenuated ethanol induced decrease in Akt and AMPK stimulated phosphorylation of Foxo3 at Thr32 and Ser413, respectively. PRKAA1 drug alcohol 19942091 Our results suggest that ALDH2 is cardioprotective against acute ethanol toxicity, possibly through inhibition of protein phosphatases, leading to enhanced Akt and AMPK activation, and subsequently, inhibition of Foxo3, apoptosis, and mitochondrial dysfunction.

PUM3 drug alcohol 28847514 Our results demonstrated that endogenous and exogenous n 3 PUFA enrichment ameliorates ethanol stimulated adipose lipolysis by increasing PDE3B activity and reducing cAMP accumulation in adipocyte, which was associated with activation of GPR120 and regulation of Ca2+/CaMKKβ/AMPK signaling, resultantly blocking fatty acid trafficking from adipose tissue to the liver, which contributing to ameliorating ethanol induced adipose dysfunction and liver injury. PUM3 drug alcohol 28847514 Our findings identify that endogenous and exogenous n 3 PUFA enrichment ameliorated alcoholic liver injury by activation of GPR120 to suppress ethanol stimulated adipose lipolysis, which provides the new insight to the hepatoprotective effect of n 3 PUFA against alcoholic liver disease.

PUM3 drug alcohol 11505055 Isolated hepatocytes from male normotensive Wistar Kyoto (WKY) rats and SHR were incubated for 60 min in the presence of labeled linoleic acid and DGLA, which are precursors of the limiting desaturation steps of PUFA biosynthesis, into a medium containing different concentrations of ethanol. PUM3 drug alcohol 11505055 First, the hepatic biogenesis of PUFA is dependent on the level of ethanol in the incubation medium. PUM3 drug alcohol 11505055 Fourth, in the presence of ethanol, the biogenesis of PUFA was altered in isolated hepatocytes from SHR that were fed the diet supplemented with n 3 PUFA, particularly via an inhibition of Delta5 desaturation. PUM3 drug alcohol 11505055 Our study showed that hepatocyte PUFA biogenesis is dependent on ethanol concentration.

PUM3 drug alcohol 27406018 Long chain PUFA, at 1.0 en%, could generally not prevent the neurotransmitter lowering effect of alcohol, but it led to an elevation of these levels in PUFA animals compared with BASE. PUM3 drug alcohol 8512244 After adjustment for age, sex, and occupational group, smokers had a substantially higher saturated fat (SFA) intake and much lower polyunsaturated fat (PUFA), principally due to a lower linoleic acid (LA) intake, resulting in a lower P:S ratio compared with never smokers, and these dietary differences remained after adjustment for alcohol consumption, BMI, and energy intake. PUM3 drug nicotine 8512244 After adjustment for age, sex, and occupational group, smokers had a substantially higher saturated fat (SFA) intake and much lower polyunsaturated fat (PUFA), principally due to a lower linoleic acid (LA) intake, resulting in a lower P:S ratio compared with never smokers, and these dietary differences remained after adjustment for alcohol consumption, BMI, and energy intake. PUM3 drug nicotine 8512244 Smokers also had different food choices obtaining more PUFA from saturated fat products such as dairy foods, lard, and ordinary margarine, and less from concentrated sources such as PUFA margarines and vegetable oils than nonsmokers.

ITGAM drug amphetamine 31282647 Systemically administered METH (1 mg/kg) was found to specifically up regulate expression of both CD11b (microglial activation marker) and the proinflammatory cytokine interleukin 6 (IL 6) mRNAs in the ventral tegmental area (VTA), but not in either the nucleus accumbens shell (NAc) or prefrontal cortex (PFC). ITGAM drug alcohol 29274031 Expression of pro inflammatory marker CD11b was higher on PD5 in alcohol exposed (AE) females compared to AE males. ITGAM drug alcohol 28973966 We found that adult rats exposed to an acute binge like level of alcohol, regardless of gestational alcohol exposure, have a robust increase in the expression of Interleukin (IL) 6 within the brain, and a significant decrease in the expression of IL 1β and CD11b.

ITGAM addiction sensitization 28941277 Chronic EtOH followed by acute stress also increased plasma endotoxin and microglial CD11b, suggesting a lasting sensitization to acute stress. ITGAM drug alcohol 27647531 Adolescent intermittent ethanol treatment increased expression of phosphorylated (activated) NF κB p65 as well as markers of microglial activation (i.e., Iba 1 and CD11b) in the adult DRN. ITGAM drug alcohol 26996510 Furthermore, both alcohol exposed and SI animals had increased levels of pro inflammatory cytokines IL 1β, TNF α, CD11b, and CCL4; in addition, CCL4 was significantly increased in alcohol exposed animals compared to SI as well.

ITGAM drug alcohol 18090004 Ethanol inhibited this LPS induced upregulation of CD11b (p < 0.001). ITGAM drug alcohol 18090004 Stimulation with IL 8 significantly upregulated CD11b expression (5.3 +/ 1.7 to 7.5 +/ 2.7, p < 0.01) and this IL 8 induced upregulation of CD11b was also inhibited by ethanol pretreatment (p < 0.001). ITGAM drug alcohol 18090004 The impairment of CD11b expression on leukocytes suggests that alcohol intake interferes with the migration of leukocytes to sites of inflammation, which may explain, in part, why alcohol intoxication increases susceptibility to infection.

ITGAM addiction intoxication 9267524 This upregulation of CD11b/c expression was abolished by ethanol intoxication. ITGAM drug alcohol 8865968 Significant gender differences exist in the extent of hepatic PMN infiltration in ethanol plus LPS treated rats, which is paralleled by very similar differences in CD11b/c adhesion molecule expression in circulating PMNs and cytokine induced neutrophil chemoattractant generation by hepatocytes and Kupffer cells. ITGAM drug alcohol 7515214 In other results, the percentage of CD8hi lymphocytes epxressing CD11b (beta integrin) is shown to be reciprocal with the percentage expressing L selectin both in normals and alcoholics. ITGAM drug alcohol 7515214 However, the regression function of CD11b vs. L selectin on CD8hi cells is different for the alcoholics than for the normals, indicating an abnormality in the regulation of the expression of these two adhesion markers. ITGAM drug cocaine 1943440 Cocaine as well as saline injected mice showed a decrease in the percentage of CD4+ CD8+ and Mac 1+ cells and an increase in B cells in the spleens of well nourished mice. ITGAM drug alcohol 3279136 Similarly, resting surface expression of the adhesive glycoprotein Mac 1 was unaffected by ethanol, but its up regulation induced by fMLP was inhibited by 25.5% at 250 mg of ethanol/dL and by 52.3% at 1000 mg/dL.

CCKAR drug amphetamine 14972658 The present studies examined this issue by testing the effects of CCKA antagonists on AMPH and novel environment induced locomotor activity following two manipulations which are known to alter mesolimbic system function: Chronic AMPH administration and chronic restraint stress (RS). CCKAR drug amphetamine 14972658 Results indicated that intra NAcc microinjections of the selective CCKA receptor antagonist PD 140548 attenuated AMPH induced and novel environment induced locomotion only in animals which had previously been exposed to chronic AMPH or chronic RS pretreatment.

CCKAR addiction relapse 12393241 These findings demonstrate that CCK A and B receptor have different roles in relapse to drug craving and further suggest that the brain areas involved in the CCK receptors on reinstatement of drug seeking are not identical.

CCKAR drug alcohol 11513220 Nominally significant differences between alcoholics and controls were found at the 85 locus of the CCKAR gene (p = .035). CCKAR drug alcohol 11513220 Our data suggest that polymorphisms of the CCK, CCKAR and CCKBR genes do not play a major role in alcohol withdrawal symptoms (even though significant associations were found among polymorphisms at the 388 and 333 loci of the CCKAR gene and hallucinations, the rate was nonsignificant after Bonferroni correction).

CCKAR drug alcohol 9922984 These results indicate that the CCK A or B receptors are selectively involved in the modulation of alcohol or cocaine intake, respectively, and suggest an involvement of the CCKergic system in the drug seeking behavior. CCKAR drug cocaine 9922984 These results indicate that the CCK A or B receptors are selectively involved in the modulation of alcohol or cocaine intake, respectively, and suggest an involvement of the CCKergic system in the drug seeking behavior.

CCKAR drug benzodiazepine 9832933 The effects of CR 2945, an antranilic acid derivative member of a novel family of non peptide CCKB receptor antagonists, have been compared with those of CAM 1028, an analogue of the CCKB receptor antagonist CI 988, L 365,260 a benzodiazepine derivative CCKB antagonist, CR 1795, an analogue of the CCKA receptor antagonist lorglumide and diazepam, a benzodiazepine receptor agonist, in several rodent screens sensitive to conventional anxiolytics. CCKAR drug opioid 9578139 Several cholecystokinin ligands were chronically administered during the development of morphine dependence: the CCKA antagonist devazepide, the CCKB antagonists PD 134,308 and L 365,260, and the CCKB agonist BC 264. CCKAR addiction dependence 9578139 Several cholecystokinin ligands were chronically administered during the development of morphine dependence: the CCKA antagonist devazepide, the CCKB antagonists PD 134,308 and L 365,260, and the CCKB agonist BC 264. CCKAR drug benzodiazepine 9276016 We previously described a series of 3 (1H indazol 3 ylmethyl) 1,5 benzodiazepine CCK A agonists exemplified by compound 1 (GW 5823), which is the first reported binding selective CCK A full agonist demonstrating oral efficacy in a rat feeding model. CCKAR addiction dependence 9276016 Binding affinity for the CCK A vs CCK B receptor showed little dependence on the structure of the C3 moiety but was affected by the nature of the second substituent at C3. CCKAR drug alcohol 9022085 The ethanol induced increase in amylase output can be completely inhibited by the CCK A receptor antagonist L 364,718 and partially inhibited by the muscarinic cholinergic antagonist atropine. CCKAR drug opioid 8947930 The overlapping distribution of opioid and cholecystokinin (CCK) peptides and their receptors (mu and delta opioid receptors; CCK A and CCK B receptors) in the central nervous system have led to a large number of studies aimed at clarifying the functional relationships between these two neuropeptides. CCKAR drug opioid 8836616 Modulation of the in vivo actions of morphine by the mixed CCKA/B receptor antagonist PD 142898. CCKAR drug opioid 8836616 The ability of a mixed CCKA/B receptor antagonist PD 142898 (benzenebutanic acid, beta [[3 (1 H indol 3 yl) 2 methyl 2 [[[(2 methyl cyclohexyl)oxy]carbonyl]amino] 1 oxopropyl]amino] [1 S [1 alpha [S*(R*)] 2 beta]]) to modulate the antinociceptive, positive reinforcing and gastrointestinal actions of morphine was investigated in the rat. CCKAR addiction reward 8836616 The ability of a mixed CCKA/B receptor antagonist PD 142898 (benzenebutanic acid, beta [[3 (1 H indol 3 yl) 2 methyl 2 [[[(2 methyl cyclohexyl)oxy]carbonyl]amino] 1 oxopropyl]amino] [1 S [1 alpha [S*(R*)] 2 beta]]) to modulate the antinociceptive, positive reinforcing and gastrointestinal actions of morphine was investigated in the rat. CCKAR drug opioid 8836616 It is argued that the effect of PD 142898 in the conditioned place preference test involves antagonism of CCKA receptors, whilst the potentiation of the antinociceptive action of morphine is mediated via blockade of CCKB receptors. CCKAR drug opioid 8836616 These results suggest that the mixed CCKA/B receptor antagonist may potentiate the analgesic action of morphine, block the development of tolerance without a concomitant increase in constipation and may also reduce the abuse potential of the opiate. CCKAR drug opioid 8818359 The ability of a selective CCKA receptor antagonist PD 140548 and a selective CCKB receptor antagonist CI 988 (formerly PD 134308) to modulate the various in vivo properties of morphine was investigated in the rat. CCKAR drug opioid 8818359 In conclusion, the results of the present study indicate that CCKA and CCKB receptors modulate different properties of morphine. CCKAR drug opioid 8818359 Thus, whilst a selective CCKA receptor antagonist blocked the rewarding properties of morphine, a selective CCKB receptor antagonist potentiated the antinociceptive action. CCKAR addiction reward 8741936 Devazepide, a CCKA receptor antagonist, impairs the acquisition of conditioned reward and conditioned activity. CCKAR addiction reward 8741936 Experiment 1 examined the effects of systemic administration of the CCKA receptor selective antagonist, devazepide (0, 0.001, 0.01, 0.1 mg/kg), on the acquisition of conditioned reward. CCKAR addiction reward 8741936 Together, these results provide converging evidence that intact CCKA function may be necessary for the development of conditioned incentive learning. CCKAR addiction aversion 8735976 Several roles of CCKA and CCKB receptor subtypes in CCK 8 induced and LiCl induced taste aversion conditioning. CCKAR drug benzodiazepine 8735976 Because the CCK antagonists affected TAC like chlordiazepoxide, blockade of CCKA and CCKB mechanisms may produce a mild anxiolytic effect. CCKAR drug opioid 8617406 For example, CCK appears to exert its anti opioid actions mainly through the activation of CCK B receptors, whereas its opioid like effects seem to result from the stimulation of CCK A receptors. CCKAR drug opioid 8004452 The CCKA receptor antagonist devazepide does not modify opioid self administration or drug discrimination: comparison with the dopamine antagonist haloperidol. CCKAR drug opioid 8004452 We previously reported that the selective cholecystokininA (CCKA) receptor antagonist, devazepide, blocked the acquisition of a morphine conditioned place preference (ref 28). CCKAR drug opioid 8004452 The present results therefore cast doubt on the potential utility of selective CCKA antagonists as treatments for opioid abuse, and further suggest that CCKB antagonists may not potentiate the subjective effects of opioids, an important finding considering that such drugs have been proposed as adjuncts to opioid therapy for the treatment of pain relief. CCKAR drug benzodiazepine 1356807 It is concluded that the reduction in aversive responding caused by pharmacological manipulation at the benzodiazepine, 5 HT receptor subtypes 5 HT1A, 5 HT1C/5 HT2 and 5 HT3 (but not at the cholecystokin CCKA or angiotensin receptors or inhibition of angiotensin converting enzyme) can be inhibited by R(+) and S( ) zacopride.

CCKAR addiction dependence 2311658 The effects of the selective CCK A antagonist L 365,031 and the selective CCK B antagonist L 365,260 on morphine analgesia and opiate tolerance and dependence in rats were examined. CAMK2A drug opioid 30260900 Association of CamK2A genetic variants with transition time from occasional to regular heroin use in a sample of heroin dependent individuals. CAMK2A drug opioid 30260900 We hypothesized, that CamK2A genetic variation may play a role in the transition from occasional to regular heroin use. CAMK2A drug opioid 30260900 Using quantitative trait association analysis, we addressed this hypothesis by correlating the self reported time interval between occasional and regular heroin use with the frequency of 12 single nucleotide polymorphisms located within the genomic region of the CamK2A gene. CAMK2A drug opioid 30260900 Our results propose that genetic variants located in the genomic region of the CamK2A gene may be involved in transition time from occasional to regular heroin use. CAMK2A drug alcohol 28714806 These different transcription patterns have been associated to the presence of alcohol, in the Camk2n1 and Gja1 genes; to the amount of ethanol consumed, in the Camk2a gene; and to the loss of control in the alcohol consumption, in the Pkp2 gene. CAMK2A drug alcohol 25579851 Alcohol sensitive proteins included calcium/calmodulin dependent protein kinase II alpha (CaMKIIα) and a network of functionally linked proteins that regulate neural plasticity and glutamate mediated synaptic activity. CAMK2A drug cocaine 25290264 To translate the rodent findings to human conditions, several CAMK2A gene polymorphisms were tested regarding their risk for a fast establishment of cocaine dependence in two independent samples of regular cocaine users from Brazil (n=688) and Switzerland (n=141). CAMK2A addiction dependence 25290264 To translate the rodent findings to human conditions, several CAMK2A gene polymorphisms were tested regarding their risk for a fast establishment of cocaine dependence in two independent samples of regular cocaine users from Brazil (n=688) and Switzerland (n=141). CAMK2A drug cocaine 25290264 A meta analysis across both samples confirmed that CAMK2A rs3776823 TT allele carriers display a faster transition to severe cocaine use than C allele carriers. CAMK2A drug alcohol 23459588 In order to compare findings in mice with the human condition, we tested 23 single nucleotide polymorphisms (SNPs) in the CAMK2A gene for their association with alcohol dependence in a population of 1333 male patients with severe alcohol dependence and 939 controls. CAMK2A addiction dependence 23459588 In order to compare findings in mice with the human condition, we tested 23 single nucleotide polymorphisms (SNPs) in the CAMK2A gene for their association with alcohol dependence in a population of 1333 male patients with severe alcohol dependence and 939 controls. CAMK2A drug alcohol 23459588 We found seven significant associations between CAMK2A SNPs and alcohol dependence, one of which in an autophosphorylation related area of the gene. CAMK2A addiction dependence 23459588 We found seven significant associations between CAMK2A SNPs and alcohol dependence, one of which in an autophosphorylation related area of the gene. CAMK2A drug opioid 20053885 Furthermore, morphine failed to induce OIH in CaMKIIalpha(T286A) point mutant mice, although wild type littermate mice developed robust OIH after repeated treatments with morphine. CAMK2A drug opioid 20053885 These data implicate, for the first time, an essential role of CaMKIIalpha as a cellular mechanism leading to and maintaining opioid induced hyperalgesia. CAMK2A drug cocaine 20010550 Chronic cocaine induced H3 acetylation and transcriptional activation of CaMKIIalpha in the nucleus accumbens is critical for motivation for drug reinforcement. CAMK2A addiction reward 20010550 Chronic cocaine induced H3 acetylation and transcriptional activation of CaMKIIalpha in the nucleus accumbens is critical for motivation for drug reinforcement. CAMK2A drug cocaine 20010550 Among the genes activated by chronic cocaine experiences, the expression of CaMKIIalpha, but not CaMKIIbeta, correlated positively with motivation for the drug. CAMK2A drug cocaine 20010550 Lentivirus mediated shRNA knockdown experiments showed that CaMKIIalpha, but not CaMKIIbeta, in the NAc shell is essential for the maintenance of motivation to self administered cocaine. CAMK2A addiction reward 20010550 These findings suggest that chronic drug use induced transcriptional activation of genes, such as CaMKIIalpha, modulated by H3 acetylation in the NAc is a critical regulatory mechanism underlying motivation for drug reinforcement. CAMK2A addiction withdrawal 19909283 Since L VGCC (L type voltage gated calcium channel) current density was doubled on drug withdrawal and up to 2 days, Ca(2+) entry through L VGCCs and perhaps subsequently through Ca(2+) permeable AMPARs are proposed to be responsible for enhanced CaMKIIalpha levels and AMPAR potentiation. CAMK2A drug amphetamine 17603807 Because the levels of both CaMKIIbeta and CaMKIIalpha play a role in neuronal function and synapse formation, the present finding of an elevated level of CaMKII beta and alpha subunit mRNA in the amphetamine sensitized model of psychosis points to the possibility of dysregulated levels of CaMKII subunits in human psychosis. CAMK2A addiction withdrawal 16616767 Opiate withdrawal induces dynamic expressions of AMPA receptors and its regulatory molecule CaMKIIalpha in hippocampal synapses. CAMK2A drug benzodiazepine 15009662 Most transcript changes were transient except for the decrease of the CaMKIIalpha transcript which persisted even 40 h after the single dose of diazepam. CAMK2A drug opioid 14706789 To clarify this issue we explored mRNA and protein expression of CaMKIIalpha in spinal cord tissue from control and morphine treated mice using real time polymerase chain reaction, Western blot analysis and confocal microscopy. CAMK2A drug opioid 14706789 The results indicate that the levels of CaMKIIalpha mRNA and protein were robustly increased in spinal cord tissue from morphine treated mice. CAMK2A drug opioid 14706789 In addition, the abundance of phosphorylated CaMKIIalpha was increased in spinal cord tissue from morphine treated mice. CAMK2A drug opioid 14706789 We conclude that enhanced CaMKIIalpha expression and activity in spinal cord tissue may contribute to the development of morphine tolerance in mice.

TST drug alcohol 29704590 The results revealed that alcohol abstinence group depicted increased immobility time in FST and TST. TST drug opioid 28028518 Chronic morphine administration caused depression and anxiety as observed by FST, EPM, and TST and decreased motor activity in OFT and caused impairment in learning and memory performance in MWM. TST drug nicotine 26512426 Nicotine dependent animals indicated a reflective depression and anxiety in a dose dependent manner in FST, EPM, and TST, which were significantly different from the control group and also can significantly attenuate the motor activity and anxiety in OFT. TST drug psychedelics 25702084 The anti immobility effect of creatine (1 mg/kg, po) or ketamine (a fast acting antidepressant, 1 mg/kg, ip) in the TST was prevented by pretreatment of mice with caffeine (3 mg/kg, ip, nonselective adenosine receptor antagonist), 8 cyclopentyl 1,3 dipropylxanthine (DPCPX) (2 mg/kg, ip, selective adenosine A1 receptor antagonist), and 4 (2 [7 amino 2 {2 furyl}{1,2,4}triazolo {2,3 a}{1,3,5}triazin 5 yl amino]ethyl) phenol (ZM241385) (1 mg/kg, ip, selective adenosine A2A receptor antagonist). TST drug psychedelics 25702084 Moreover, the administration of subeffective doses of creatine or ketamine combined with N 6 cyclohexyladenosine (CHA) (0.05 mg/kg, ip, selective adenosine A1 receptor agonist), N 6 [2 (3,5 dimethoxyphenyl) 2 (methylphenyl)ethyl]adenosine (DPMA) (0.1 mg/kg, ip, selective adenosine A2A receptor agonist), or dipyridamole (0.1 μg/mouse, icv, adenosine transporter inhibitor) produced a synergistic antidepressant like effect in the TST. TST drug psychedelics 25702084 These results indicate that creatine, similarly to ketamine, exhibits antidepressant like effect in the TST probably mediated by the activation of both adenosine A1 and A2A receptors, further reinforcing the potential of targeting the purinergic system to the management of mood disorders. TST addiction reward 25702084 These results indicate that creatine, similarly to ketamine, exhibits antidepressant like effect in the TST probably mediated by the activation of both adenosine A1 and A2A receptors, further reinforcing the potential of targeting the purinergic system to the management of mood disorders. TST drug alcohol 22651960 We have found potential antidepressant like effect of acamprosate at doses of 100 400 mg/kg in the TST in C57BL/6J mice. TST drug alcohol 22651960 Furthermore we have shown that the antidepressant like effect of acamprosate used at a dose of 200 mg/kg was dependent on NMDA and mGlu5 receptor blockade, since NMDA (25 mg/kg) and mGlu5 receptor positive allosteric modulator, CDPPB (3 mg/kg), antagonized its activity in the TST. TST drug opioid 20014914 Currently, tuberculin skin testing (TST) is recommended for patients enrolling in methadone maintenance treatment (MMT), but not for those enrolling in buprenorphine maintenance treatment (BMT). TST drug opioid 20014914 These results confirm a similar high prevalence of TST positivity in opioid dependent patients enrolling in MMT and BMT programs. TST drug opioid 20014914 These data suggest the importance of incorporating TST screening in emerging BMT programs as a mechanism to provide increased detection and treatment of tuberculosis infection in opioid dependent patient populations. TST drug psychedelics 18458881 One week after a single administration of ketamine (50 160 mg/kg), otherwise experimentally naive rats and mice were tested either in the forced swim test (FST) or the tail suspension test (TST). TST drug opioid 17122073 The first relies on naloxone induced withdrawal in morphine dependent (MD) OVX rats, resulting in an acute rise in TST. TST addiction withdrawal 17122073 The first relies on naloxone induced withdrawal in morphine dependent (MD) OVX rats, resulting in an acute rise in TST. TST drug opioid 17122073 Further evaluation showed that orally administered DVS acutely and dose dependently (10 100 mg/kg) abated a naloxone induced rise in TST of MD rats and alleviated OVX induced temperature dysfunction in the telemetry model. TST drug opioid 15527744 The first model is based on measurement of the tail skin temperature (TST) increase following naloxone induced withdrawal in morphine dependent ovariectomized (OVX) rats (MD model), while the second model relies on telemetric assessment of diurnal TST changes in ovariectomized rats (telemetry model). TST addiction withdrawal 15527744 The first model is based on measurement of the tail skin temperature (TST) increase following naloxone induced withdrawal in morphine dependent ovariectomized (OVX) rats (MD model), while the second model relies on telemetric assessment of diurnal TST changes in ovariectomized rats (telemetry model). TST drug opioid 15527744 Treatment with a 5 HT(2A/2C) receptor agonist, ( ) 2,5 dimethoxy 4 iodoamphetamine hydrochloride (DOI), prevented the naloxone induced TST increase in the MD model and restored normal active phase TST in the telemetry model. TST drug opioid 15527744 Interestingly, MDL 100907 increased TST in both models when given alone, with the TST increase occurring prior to the naloxone induced flush in the MD model. TST drug opioid 15002736 In addition, the total serum testosterone (TST) concentrations in male rats at different times of morphine administration and abstinence were measured. TST drug opioid 15002736 Acute and chronic administration of morphine severely inhibited the sexual behavior of the rats and lowered their TST concentrations. TST drug opioid 15002736 TST concentrations recovered to normal within 24 h after the last morphine injection, while sexual behavior remained suppressed for at least 7 days. TST drug opioid 15002736 Electroacupuncture (2/100 Hz alternately) administered once daily for 7 days during morphine withdrawal facilitated the recovery of male sexual behavior and increased TST concentrations to above normal. TST addiction withdrawal 15002736 Electroacupuncture (2/100 Hz alternately) administered once daily for 7 days during morphine withdrawal facilitated the recovery of male sexual behavior and increased TST concentrations to above normal. TST addiction reward 11420067 Successive conditioning phases were: free shaping (FS), continuous reinforcement (CRF), operant extinction (EXT), successive discrimination (DIS) and two stimuli test (TST). TST drug alcohol 11420067 Finally, alcohol deteriorated behavioral inhibition (DIS and TST) tested immediately after drinking. TST drug alcohol 8750043 Two statistically significant interactions were found: consistent with our hypothesis, stimulant abusers showed greater total sleep (TST) and REM sleep during acute withdrawal than subacute withdrawal, compared with alcoholics.

TST drug opioid 8187842 Following addiction to morphine, young and aged rats were evaluated for tail skin temperature (TST), rectal temperature (Tr), behavior, rhinorrhea, lacrimation, salivation, and diarrhea in response to naloxone administration. TST addiction addiction 8187842 Following addiction to morphine, young and aged rats were evaluated for tail skin temperature (TST), rectal temperature (Tr), behavior, rhinorrhea, lacrimation, salivation, and diarrhea in response to naloxone administration. TST addiction withdrawal 8187842 Young rats showed the expected TST increase and Tr decline in response to withdrawal. TST drug opioid 8187842 The majority of aged rats showed an exaggerated TST response to naloxone, while some aged rats failed to exhibit any TST response to withdrawal. TST addiction withdrawal 8187842 The majority of aged rats showed an exaggerated TST response to naloxone, while some aged rats failed to exhibit any TST response to withdrawal. TST drug opioid 1907349 The present study was designed to evaluate the effects of E2 CDS vs. E2, on the tail skin temperature (TST) surge associated with administration of naloxone to morphine dependent rats, an animal model for menopausal hot flush. TST drug opioid 1907349 The mean maximal elevation in TST of the control animals was 6.4 +/ 0.2 degrees C. A single injection of E2 CDS attenuated the naloxone induced rise in TST by 25%, while multiple injections resulted in significant attenuation of the rise in TST (3.4 +/ 0.6). TST drug opioid 1967837 Adrenalectomy and peripheral administration of propranolol (10 mg/kg sc) both resulted in a significant attenuation of the surge in TST and the fall in core temperature in the morphine dependent rat which suggest some peripherally mediated event is necessary to produce the full skin temperature surge. TST drug opioid 1967837 Collectively, the data suggest a role for the adrenal gland and adrenergic receptors in producing the surge in TST in morphine dependent rats. TST drug opioid 2388522 Naloxone caused a tail skin temperature (TST) response of 5.7 +/ 0.5 degrees C in morphine dependent rats. TST drug opioid 2388522 Intraperitoneal administration 2 deoxyglucose (2DG) caused TST responses in placebo treated and morphine dependent rats of 4.8 +/ 0.6 and 6.2 +/ 0.5 degrees C, respectively. TST drug opioid 2388522 These data indicate that the activation of the sympathetic nervous system by cellular glucoprivation causes a TST response which is equivalent in magnitude to that induced by precipitating withdrawal with naloxone. TST addiction withdrawal 2388522 These data indicate that the activation of the sympathetic nervous system by cellular glucoprivation causes a TST response which is equivalent in magnitude to that induced by precipitating withdrawal with naloxone. TST drug opioid 2388522 This effect of 2DG appears to be mediated by the brain, since icy administration of 2DG caused a TST response, similar to that induced by naloxone treatment of morphine dependent rats. TST drug opioid 2274603 Studies were undertaken to determine the effects of acute alterations in plasma glucose levels on the tail skin temperature (TST) response of morphine dependent rats to naloxone precipitated withdrawal. TST addiction withdrawal 2274603 Studies were undertaken to determine the effects of acute alterations in plasma glucose levels on the tail skin temperature (TST) response of morphine dependent rats to naloxone precipitated withdrawal. TST drug opioid 2274603 In morphine dependent rats, treatment with dextrose at doses of 0.5 or 2.5 g/kg did not alter the normal 6.0 +/ 0.3 degrees C TST response to naloxone. TST drug opioid 2274603 However, treatment with 5, 10 or 20 g dextrose/kg, which increased plasma glucose to 250 mg/dl or greater, blocked the TST response during morphine withdrawal. TST addiction withdrawal 2274603 However, treatment with 5, 10 or 20 g dextrose/kg, which increased plasma glucose to 250 mg/dl or greater, blocked the TST response during morphine withdrawal. TST drug opioid 2274603 In contrast, an IV injection of 2.5 IU insulin (Na porcine)/kg, which reduced plasma glucose for 2 h, caused a delayed TST response of 4.7 +/ 0.4 degrees C in control rats and exaggerated the TST response normally observed in morphine dependent rats treated with naloxone. TST drug opioid 2670064 Administration of naloxone to these animals results in a surge in LH secretion which precedes the elevation in tail skin temperature (TST). TST drug opioid 2670064 Central administration of naloxone was without effect in controls but produced a 5 6 degree C rise of TST in the morphine dependent rat while central administration of 10 microliters of the saline vehicle produced no changes in TST in either group. TST drug opioid 2670064 Administration of 5 or 10 micrograms of the LH RH agonist (Des Gly10, [im Bzl D His6]LH RH ethylamide) into the LV produced a significantly greater elevation in TST (4 degrees C) in the morphine dependent rats compared to a negligible rise in TST in the control rats; however, administration of a larger dose of 20 micrograms of the LH RH agonist produced similar TST responses of about 4 degrees C in both groups. TST drug opioid 2670064 In a subsequent study central administration of the LH RH agonist (5 micrograms/10 microliters) resulted in a similar rise in serum LH in both control and morphine dependent rats, suggesting that the elevation in TST is not closely associated with LH secretion. TST drug opioid 2670064 Further support for a role of LH RH in our animal model was obtained following central administration of an LH RH antagonist [(D Phe2.6, Pro3]LH RH) which blocked the rise in TST associated with systemic administration of naloxone (1 mg/kg, s.c.) in morphine dependent rats. TST drug opioid 2825916 Studies were undertaken to evaluate the role of central noradrenergic neurons in the tail skin temperature (TST) surge that accompanies morphine withdrawal in the rat. TST addiction withdrawal 2825916 Studies were undertaken to evaluate the role of central noradrenergic neurons in the tail skin temperature (TST) surge that accompanies morphine withdrawal in the rat. TST drug opioid 2825916 A 5 degrees C increase in TST and a 1 2 degrees C decrease in rectal temperature (Tr) was observed following administration of a dose of naloxone HCl (NAL, 1 mg/kg, s.c.) which precipitated withdrawal in morphine dependent rats. TST addiction withdrawal 2825916 A 5 degrees C increase in TST and a 1 2 degrees C decrease in rectal temperature (Tr) was observed following administration of a dose of naloxone HCl (NAL, 1 mg/kg, s.c.) which precipitated withdrawal in morphine dependent rats. TST drug opioid 2825916 injection of clonidine HCl, a partial alpha 2 adrenergic agonist did not alter TST in morphine dependent animals. TST drug opioid 2825916 given 10 min prior to the administration of NAL completely blocked the TST response to the opiate antagonist in the morphine dependent animals. TST drug opioid 2825916 failed to alter TST when administered alone, but the highest dose significantly reduced the TST response to naloxone in the morphine dependent rat. TST drug opioid 2825916 Collectively, these data indicate that brain noradrenergic neurons play a role in the TST surge which accompanies NAL precipitated morphine withdrawal, and that the TST and Tr responses can be dissociated in the morphine dependent rat.

TST addiction withdrawal 6092986 Naloxone precipitated morphine withdrawal caused a prompt increase (4.9 +/ 0.76 degrees C) in tail skin temperature (TST) and a subsequent decline in Tr ( 2.8 degrees C). TST drug opioid 6092986 Similarly, naloxone administration to HYP rats caused a dramatic TST response which was coincident with the onset of severe HYP. TST drug opioid 6092986 This effect of naloxone was maximal at 7 weeks of tumor growth when a TST response of 4.8 +/ 0.3 degrees C was observed but was not evident prior to or 1 week following tumor inoculation, when serum prolactin levels were low. TST drug opioid 6092986 The TST response to naloxone in chronic HYP exhibited distinct pulses with an amplitude of 3.4 +/ 0.4 degrees C and a frequency of 2.2 +/ 0.5 pulses per 120 min. TST drug opioid 6092986 These effects of chronic HYP on the TST response to naloxone were not influenced by ovariectomy, suggesting that changes in ovarian secretions were not involved in the response. TST drug opioid 6835016 In response to precipitous, naloxone induced withdrawal, rats showed surges in tail skin temperature (TST) which were similar in magnitude (4.8 to 7.2 degrees C) and duration (60 to 90 min.)

MAPK1 drug psychedelics 28948570 Since GluN2B, via inhibition of ERK, regulates the membrane expression of GluA1, we measured ERK2 phosphorylation in the crude synaptosomal fraction of these brain regions, which was significantly reduced suggesting that ketamine induced phosphorylation of αCaMKII promotes GluN2B (S1303) phosphorylation that, in turn, inhibits ERK 2 signaling, an effect that results in reduced membrane expression and phosphorylation of GluA1.

MAPK1 drug cocaine 26398380 In cocaine pretreated caged rats no changes in p CREB/CREB levels were observed, while ERK2 levels either decreased (frontal cortex) or increased (nucleus accumbens). MAPK1 drug opioid 26349634 In mice pretreated with all opioids, baseline ERK2 activation levels were unchanged and increased in response to quinpirole. MAPK1 drug opioid 26349634 However, quinpirole induced ERK2 activation was significantly higher than drug naïve animals only in the morphine pretreated mice.

MAPK1 drug opioid 24950452 Ultra low dose morphine intensively increased pERK1 contents in the PAG and cortex and, to a lesser extent, increased cortical ERK2 and JNK phosphorylation. MAPK1 drug cocaine 24452697 MPH + FLX, or cocaine exposure in juvenile mice increased mRNA expression of ERK2 and its downstream targets (CREB, cFos, and Zif268), and increased protein phosphorylation of ERK2 and CREB 2 months after drug exposure.

MAPK1 addiction reward 24296091 During three phases of morphine induced CPP, the expression levels of ERK1 and ERK2 mRNA were altered in various brain regions. MAPK1 drug opioid 24296091 In the PFC, the expression levels of ERK1 and ERK2 mRNA were increased after chronic morphine injection (p=0.003, p=0.000), and did not return to the basal level after extinction training (p=0.025, p=0.000), but decreased after a priming injection (p=0.000, p=0.000). MAPK1 drug opioid 24296091 Different from other brain regions, the expression levels of ERK1 and ERK2 mRNA were decreased in three phases of morphine induced CPP in the hippocampus (ERK1: p=0.000, p=0.040, p=0.000; ERK2: p=0.000, p=0.000, p=0.000, respectively).

MAPK1 drug cocaine 23970867 The abundance of surrogate markers of dopamine signaling and plasticity in the dorsolateral prefrontal cortex (DLPFC), orbitofrontal cortex (OFC), and anterior cingulate cortex (ACC) were examined: glycosylated and non glycosylated forms of the dopamine transporter (efficiency of dopamine transport), tyrosine hydroxylase (TH; marker of dopamine synthesis) and phosphorylated TH at Serine 30 and 40 (markers of enzyme activity), extracellular signal regulated kinase 1 and 2 (ERK1 and ERK 2), and phosphorylated ERK1 and ERK2 (phosphorylates TH Serine 31; markers of synaptic plasticity), and markers of synaptic integrity, spinophilin and post synaptic density protein 95 (roles in dopamine signaling and response to cocaine).

MAPK1 drug cocaine 21940447 Intra NAc pharmacological manipulations indicate that the Ca(v)1.2 activated CaM kinase II (CaMKII) mediates cocaine induced increase in S831 P GluA1 and that both Ca(v)1.2 activated CaMKII and extracellular signal regulated kinase 2 (ERK2) mediate the increase in GluA1 cell surface levels specific to the sensitized response.

MAPK1 drug nicotine 21420997 In the nicotine treated groups, the levels of phosphorylated CREB and ERK2 in the PFC were increased in HIV 1Tg rats, but decreased in F344 animals. MAPK1 drug nicotine 21420997 Moreover, repeated nicotine administration reduced phosphorylated ERK2 in the VTA of HIV 1Tg rats and in the NAc of F344 rats, but had no effect on phosphorylated CREB, indicating a region specific change of intracellular signaling.

MAPK1 addiction withdrawal 21276808 The maintenance of CP AMPARs in NAc synapses during withdrawal is accompanied by activation of CaMKII and ERK2 but not CaMKI. MAPK1 drug nicotine 21172385 Since activation of extracellular signal related kinase (ERK2) is involved in the rewarding effects of several classes of drugs of abuse, we then measured the level of ERK2 phosphorylation in the nucleus accumbens shell (NACsh) and core (NACco) of GAL / and GAL+/+ mice following re exposure to the CPP chamber previously paired with nicotine as a marker of mesolimbic system activation.

GARS1 drug alcohol 26158502 GlyRs are relevant for the effects of ethanol because they are found in the spinal cord and brain stem where they primarily express the α1 subunit. GARS1 drug alcohol 26158502 Here, we review data on the following aspects of ethanol effects on GlyRs: (1) direct interaction of ethanol with amino acids in the extracellular or transmembrane domains, and indirect mechanisms through the activation of signal transduction pathways; (2) analysis of α2 and α3 subunits having different sensitivities to ethanol which allows the identification of structural requirements for ethanol modulation present in the intracellular domain and C terminal region; (3) Genetically modified knock in mice for α1 GlyRs that have an impaired interaction with G protein and demonstrate reduced ethanol sensitivity without changes in glycinergic transmission; and (4) GlyRs as potential therapeutic targets. GARS1 drug alcohol 25678534 Ethanol enhances the function of brain GlyRs, and the GlyRα1 subunit is associated with some of the behavioral actions of ethanol, such as loss of righting reflex. GARS1 drug alcohol 25589412 Previous studies have shown that the effect of ethanol onglycine receptors (GlyRs) containing the a1 subunit is affected by interaction with heterotrimeric G proteins (Gβγ). GARS1 addiction sensitization 25589412 GlyRs containing the α3 subunit are involved in inflammatory pain sensitization and rhythmic breathing and have received much recent attention. GARS1 drug alcohol 25589412 Residue A254 in TM2, the α3L splice cassette, and the C terminal domain of α3GlyRs are determinants for low ethanol sensitivity and form the molecular basis of subtype selective modulation of GlyRs by alcohol. GARS1 drug alcohol 24686030 Our previous work in rats has demonstrated that accumbal glycine receptors (GlyRs) are involved in mediating the dopamine activating effects of ethanol, and in modulating ethanol intake. GARS1 drug alcohol 24686030 The dopamine increasing effect of systemic ethanol and the drug induced change in neurotransmission in vitro, as measured by microdialysis and field potential recordings, were dependent on GlyRs in nAc.

GARS1 drug alcohol 24264816 These findings identify extrasynaptic GlyRs as critical regulators of DR excitability and a novel molecular target for ethanol. GARS1 drug alcohol 22238211 In the current study, we tested the hypothesis that the activation of the presynaptic GlyRs in the VTA might interfere with ethanol self administration. GARS1 drug alcohol 22238211 The effects of glycine probably were mediated by strychnine sensitive GlyRs, because the coinjection of glycine and strychnine reduced neither ethanol intake in the home cages nor lever press responding for ethanol in the operant chambers. GARS1 addiction reward 22238211 The effects of glycine probably were mediated by strychnine sensitive GlyRs, because the coinjection of glycine and strychnine reduced neither ethanol intake in the home cages nor lever press responding for ethanol in the operant chambers. GARS1 drug alcohol 22238211 Thus, GlyRs in the VTA may play a critical role in ethanol self administration in animals chronically exposed to ethanol. GARS1 drug alcohol 22238211 Therefore, drugs targeting GlyRs may be beneficial for alcoholics. GARS1 drug alcohol 22037202 Thus, in addition to reducing ethanol action on the GlyRs, these mutations reduced glycinergic inhibition, which may also alter sensitivity to GABAergic drugs. GARS1 drug alcohol 21790901 Our previous research suggested that glycine receptors (GlyRs) in the nucleus accumbens (nAc) play a major part in mediating the dopamine elevating properties of ethanol and are highly involved in the ethanol intake reducing effect of acamprosate. GARS1 drug alcohol 21790901 Taken together with our previous data demonstrating the importance of accumbal GlyRs both in ethanol induced elevation of nAc dopamine and in ethanol consumption, it is plausible that the effects of MPEP treatment, on dopamine output and on ethanol intake, may be mediated via interaction with the same neuronal circuitry that previously has been demonstrated for ethanol, taurine and acamprosate. GARS1 drug alcohol 19860810 Glycine receptors (GlyRs) in the nucleus accumbens (nAc) and nicotinic acetylcholine receptors (nAChRs) in the ventral tegmental area (VTA) have been suggested to be involved in the positive reinforcing and dopamine elevating effects of ethanol. GARS1 addiction reward 19860810 Glycine receptors (GlyRs) in the nucleus accumbens (nAc) and nicotinic acetylcholine receptors (nAChRs) in the ventral tegmental area (VTA) have been suggested to be involved in the positive reinforcing and dopamine elevating effects of ethanol. GARS1 drug alcohol 19860810 These results suggest that both systemic and local application of acamprosate elevate extracellular dopamine levels in the nAc by activating accumbal GlyRs, and, secondarily, tegmental nAChRs. GARS1 drug alcohol 19860809 We have previously demonstrated that strychnine sensitive glycine receptors (GlyRs) in the nucleus accumbens (nAc) and nicotinic acetylcholine receptors (nAChRs) in the ventral tegmental area are involved in mediating ethanol (EtOH) induced elevation of dopamine in the rat mesolimbic dopamine system. GARS1 drug alcohol 19860809 This neuronal circuitry was also demonstrated to mediate dopamine elevation in the nAc after both taurine, an endogenous agonist of GlyRs, and acamprosate, a synthetic derivate of homotaurine. GARS1 drug alcohol 19860809 The aim of this study was to investigate whether the EtOH intake reducing effect of acamprosate involves accumbal GlyRs. GARS1 drug alcohol 19860809 Based on current and previous results, we suggest that acamprosate primarily interacts with accumbal GlyRs and secondarily with ventral tegmental nAChRs, in a similar manner to that previously observed with EtOH and taurine. GARS1 drug alcohol 19860809 The interaction between acamprosate and GlyRs does not only influence dopamine output in the nAc but also EtOH consumption, giving further support for our hypothesis that GlyRs are of importance in EtOH reinforcement.

GARS1 addiction reward 19543795 Glycine receptors (GlyRs) in the nucleus accumbens (nAc) have recently been suggested to be involved in the reinforcing and dopamine elevating properties of ethanol via a neuronal circuitry involving the VTA. GARS1 drug alcohol 19543795 Apart from ethanol, both glycine and taurine have the ability to modulate dopamine output via GlyRs in the same brain region. GARS1 drug alcohol 19389199 The results are in line with previous findings and it is suggested that the effects observed involve interference with accumbal GlyRs and are related to the alcohol consumption modulating effect of Org 25935. GARS1 drug alcohol 17098748 Previous findings from our group indicate that accumbal glycine receptors (GlyRs) are involved in mediating the dopamine (DA) activating effects of ethanol (EtOH), and that administration of glycine locally into the nucleus accumbens (nAc) reduces EtOH consumption in EtOH high preferring rats. GARS1 drug alcohol 16820013 The present results suggest that taurine may be an endogenous ligand for GlyRs in the nAcc and that the taurine induced elevation of DA levels in this area, similarly to that observed after local ethanol, is mediated via a neuronal loop involving endogenous activation of nAChRs in the VTA. GARS1 addiction reward 15654289 The mechanisms underlying this DA activation and how they relate to EtOH reinforcement remain to be elucidated, but recent data indicate that glycine receptors (GlyRs) in the nAc may be involved.

PRKCG drug opioid 27329776 As PKCg activity related to N methyl D aspartate receptor activation is critical in opioid tolerance, these results help to understand the mechanisms of BMSC produced long term antihyperalgesia, which requires opioid receptors in rostral ventromedial medulla and apparently lacks the development of tolerance.

PRKCG drug opioid 20359526 These observations suggest that spinal ERK2, P38 and PKCgamma are likely involved in multiple adaptive responses following systemic morphine administration, whereas DYN and CGRP may contribute selectively to the development of antinociceptive tolerance. PRKCG addiction sensitization 19607847 Several mechanisms have been suggested to be responsible for OIH such as sensitization of peripheral nociceptors, enhanced production/release of glutamate and neuropeptides in the spinal cord, protein kinase C gamma induced signaling, and/or enhanced descending facilitation of nociceptive pathways from the rostral ventromedial medulla; however signaling pathways known to lead to directly to OIH remain undiscovered. PRKCG drug alcohol 17566760 More recent studies using transgenic mice have identified two isozymes, PKCgamma and PKCepsilon, that have opposing roles in mediating the behavioral effects of ethanol. PRKCG drug alcohol 17566760 Genetic deletion of PKCgamma produces mice with a high ethanol drinking phenotype which are impulsive and require high levels of ethanol to reach intoxication, perhaps modeling the human condition of individuals who are at risk for developing alcoholism.

PRKCG drug alcohol 17566760 These findings suggest that drugs targeting PKCgamma and PKCepsilon may be useful to curb excessive drinking, the key symptom of alcohol use disorders. PRKCG drug alcohol 17508994 The rationale for this study was based on the impulsive behavior and increased ethanol consumption observed in the protein kinase C gamma (PKC gamma) deficient mouse model. PRKCG drug alcohol 17508994 The rationale for this study was based on the impulsive behavior and increased ethanol consumption observed in the protein kinase C gamma (PKC gamma) deficient mouse model. PRKCG addiction relapse 17508994 Two composite behavioral disinhibition phenotypes and their component behavioral scores [conduct disorder, attention deficit hyperactivity disorder (ADHD), substance experimentation (SUB) and novelty seeking] were examined for association with five independent PRKCG single nucleotide polymorphisms (SNPs). PRKCG drug opioid 16190878 The present study was designed to investigate the role of protein kinase C (PKC) in this process by estimating changes in PKCalpha and PKCgamma immunoreactivity, and whether pharmacological inhibition of PKC would attenuate morphine withdrawal induced c Fos expression and changes in tyrosine hydroxylase (TH) immunoreactivity levels in the PVN and nucleus tractus solitarius/ ventrolateral medulla (NTS/VLM).

PRKCG drug opioid 15830100 During morphine dependence, but not naloxone precipitated withdrawal, PKC gamma in the spinal cord translocated from cytosol to membrane fraction, and intrathecal administration of CHE did not change the expression of PKC gamma in the spinal cord of naloxone precipitated withdrawal rats. PRKCG addiction dependence 15830100 During morphine dependence, but not naloxone precipitated withdrawal, PKC gamma in the spinal cord translocated from cytosol to membrane fraction, and intrathecal administration of CHE did not change the expression of PKC gamma in the spinal cord of naloxone precipitated withdrawal rats.

PRKCG addiction withdrawal 15655532 The present studies were designed to test the hypothesis that neuronal specific protein kinase Cgamma (PKCgamma) plays a critical role in acute ethanol withdrawal hyper responsiveness in spinal cord. PRKCG drug alcohol 15655532 Exposure to ethanol (100 mM) induced PKCgamma translocation from the nucleus to cytoplasm in motor neurons. PRKCG drug alcohol 15655532 The results show that PKCgamma mediates ethanol withdrawal hyper responsiveness in spinal motor neurons; the results may be relevant to some symptoms of ethanol withdrawal in vivo. PRKCG addiction withdrawal 15655532 The results show that PKCgamma mediates ethanol withdrawal hyper responsiveness in spinal motor neurons; the results may be relevant to some symptoms of ethanol withdrawal in vivo. PRKCG drug opioid 15379885 Additionally, acute as well as chronic intraperitoneal morphine administration changed the abundance of PKC gamma, gamma1 subunit of GABAA and hsp70 genes. PRKCG drug opioid 15355330 Using immunoblot analysis, we confirmed that the increased level of protein kinase Cgamma (PKCgamma) isoform was observed in the limbic forebrain of ICR mice conditioned with morphine. PRKCG drug opioid 15355330 The present data provide direct evidence that the activation of mGlu5 receptor linked to the increased PKCgamma isoform in the mouse limbic forebrain is implicated in the development of rewarding effect of morphine. PRKCG addiction withdrawal 15275778 Consistent with this finding, a specific peptide inhibitor of calcium independent PKC, but not an inhibitor of calcium dependent PKC gamma, blocked withdrawal hyperresponsiveness of the sVRP. PRKCG drug opioid 15275778 Similarly, in vivo in 7 day old rat pups, inhibition of PKC, but not PKC gamma, prevented thermal hyperalgesia precipitated by naloxone at 30 min post morphine. PRKCG drug opioid 15275778 In addition the difference between naloxone precipitated and spontaneous withdrawal in vivo suggests that in postnatal day 7 rats, morphine exposure produces an early phase of primary afferent sensitization dependent upon PKC translocation, followed by a later phase involving spinal sensitization mediated by PKC gamma. PRKCG addiction sensitization 15275778 In addition the difference between naloxone precipitated and spontaneous withdrawal in vivo suggests that in postnatal day 7 rats, morphine exposure produces an early phase of primary afferent sensitization dependent upon PKC translocation, followed by a later phase involving spinal sensitization mediated by PKC gamma.

PRKCG drug alcohol 12649378 Ethanol differentially enhances hippocampal GABA A receptor mediated responses in protein kinase C gamma (PKC gamma) and PKC epsilon null mice. PRKCG drug alcohol 12649378 We examined acute effects of ethanol on GABA(A) receptor mediated inhibitory postsynaptic currents (IPSCs) in mice lacking either PKCgamma (PKCgamma( / )) or PKCepsilon (PKCepsilon( / )) isozymes and compared the results to those from corresponding wild type littermates (PKCgamma(+/+) and PKCepsilon(+/+)). PRKCG drug alcohol 12649378 Ethanol (80 mM) enhanced the IPSC response amplitude and area in PKCgamma(+/+) mice, but not in the PKCgamma( / ) mice. PRKCG drug alcohol 12649378 These results suggest that PKCgamma and PKCepsilon signaling pathways reciprocally modulate both ethanol enhancement of GABA(A) receptor function and hypnotic sensitivity to ethanol. PRKCG drug opioid 11731061 Reduced development of tolerance to the analgesic effects of morphine and clonidine in PKC gamma mutant mice. PRKCG drug opioid 11731061 These results indicate that PKC gamma contributes to the development of tolerance to the analgesic effects of both morphine and clonidine. PRKCG drug opioid 11731061 To assess the contribution of PKC gamma to this process, we studied the responses of wild type and mutant mice to an intraplantar injection of formalin (a model of persistent pain) following chronic morphine treatment. PRKCG drug opioid 11731061 Although morphine tolerance increased formalin evoked persistent pain behavior and Fos LI in wild type mice, there was no difference between placebo and morphine treated mutant mice, suggesting that PKC gamma also contributes to chronic morphine induced changes in nociceptive processing. PRKCG drug alcohol 11427306 The protein level of membrane bound PKCalpha and PKCgamma isoforms, which are defined as Ca2+ dependent PKC isoforms (cPKC), in the limbic forebrain during chronic ethanol treatment was significantly increased, whereas the levels of both were significantly decreased in the frontal cortex. PRKCG drug opioid 11246146 The protein level of PKCgamma was significantly up regulated in membrane preparations of the limbic forebrain obtained from the morphine conditioned mice compared to that from the saline conditioned mice. PRKCG drug opioid 11246146 Furthermore, we investigated the rewarding properties of morphine in mice lacking PKCgamma gene. PRKCG drug opioid 11246146 A significant place preference was observed following treatment with morphine in wild type mice, whereas such an effect of morphine was not found in PKCgamma knockout mice. PRKCG drug opioid 11246146 These findings suggest that activated PKCgamma in the limbic forebrain following the treatment with morphine may be critical for the development and/or maintenance of reinforcing effects induced by morphine in mice. PRKCG addiction reward 11246146 These findings suggest that activated PKCgamma in the limbic forebrain following the treatment with morphine may be critical for the development and/or maintenance of reinforcing effects induced by morphine in mice. PRKCG drug opioid 11144149 We therefore propose that PKC gamma may play a critical role in the development of morphine tolerance. PRKCG addiction sensitization 10375678 Protein kinase C (PKC) is thought to have a role in sensitization of dorsal horn neurons in certain pain states, and a recent study has reported that mice which lack the gamma isoform (PKCgamma) show reduced neuropathic pain after peripheral nerve injury. PRKCG drug opioid 10375678 Dual immunofluorescence labelling showed that PKCgamma was not randomly distributed amongst non GABAergic neurons, since it was present in 76% of cells with neurotensin and 45% of those with somatostatin, but only 5% of those with the mu opioid receptor (MOR 1).

GAD2 drug nicotine 31744841 This, coupled with expression data demonstrating coexpression of vesicular glutamate transporter 2 (VGluT2) and glutamate decarboxylase 2 (Gad2) in mVTA neurons, suggests that nicotine is able to stimulate GABA corelease from mVTA VGluT2+ neurons.

GAD2 drug opioid 30682345 Pharmacological activation of dopamine D4 receptor modulates morphine induced changes in the expression of GAD65/67 and GABAB receptors in the basal ganglia. GAD2 drug opioid 30682345 It has been demonstrated that the co administration of a D4R agonist together with morphine leads to a restoration of GABA signaling by preventing drug induced changes in GAD65/67 expression in the caudate putamen, globus palidus and substantia nigra. GAD2 drug cocaine 30294670 In the prelimbic PFC, both 1 and 5 d of cocaine exposure increased GAD65/67 puncta near PNN surrounded PV cells, with an increase in the GAD65/67 to VGluT1 puncta ratio after 5 d of cocaine exposure. GAD2 drug nicotine 30170085 Our results showed that in the group that received acute nicotine, both GAD65 and GAD67 protein levels were downregulated in the vHPC, but not in dHPC. GAD2 drug nicotine 30170085 Finally, using c fos/GAD65/67 double immunofluorescence, we showed that nicotine mainly increased c fos expression in non GABAergic ventral hippocampal cells, indicating that acute nicotine increases vHPC excitability. GAD2 drug cocaine 29139213 In addition, we found increased GAD65 expression after 10 but not 60 days of cocaine self administration in the rostral mesencephalic tegmental nucleus. GAD2 drug amphetamine 28351548 Based on our previous findings, we also found significant correlations between GAD67, GAT1 and parvalbumin while GAD67, GAD65 and GAT1 were positively correlated with cholecystokinin in the PRL of METH sensitized rats.

GAD2 drug opioid 27862708 In the present study, we found that reexposure to morphine paired environment significantly increased the activity of hippocampal CA3 neurons, increased the excitability of GABAergic neurons and expression of glutamic acid decarboxylase 65/67 in the caudal lateral septum (LSc) and decreased the activity of GABAergic neurons and GAD65/67 expression in ventral tegmental area (VTA), leading to activation (disinhibition) of dopaminergic neurons. GAD2 drug opioid 27862708 Inactivation of CA3 neurons attenuated GABAergic neurons activity and decreased the upregulation of GAD65/67 in LSc, prevented the dopaminergic neurons activation,and GAD65/67 downregulation in VTA and ameliorated the CPP behavior following exposure to morphine paired context.

GAD2 drug psychedelics 26068050 The results showed that chronic MDMA caused hippocampal protein deficits in adolescent and young adult rats at different levels: (1) impaired serotonergic (5 HT2A and 5 HT2C post synaptic receptors) and GABAergic (GAD2 enzyme) signaling, and (2) decreased structural cytoskeletal neurofilament proteins (NF H, NF M and NF L). GAD2 drug nicotine 26041923 In mice expressing Leu9'Ser α4 nAChR subunits in VTA GABAergic neurons (Gad2(VTA):Leu9'Ser mice), subreward threshold doses of nicotine were sufficient to selectively activate VTA GABAergic neurons and elicit acute hypolocomotion, with subsequent nicotine exposures eliciting tolerance to this effect, compared to control animals. GAD2 drug nicotine 26041923 In the conditioned place preference procedure, nicotine was sufficient to condition a significant place preference in Gad2(VTA):Leu9'Ser mice at low nicotine doses that failed to condition control animals.

NCAM1 addiction sensitization 17658493 Here, we investigated the expression levels of a neural cell adhesion molecule (NCAM) and a polysialylated form of the neuronal cell adhesion molecule (PSA NCAM) as markers of synaptic plasticity, in the associative learning mechanisms related to behavioral sensitization. NCAM1 drug amphetamine 17658493 To achieve our goal we examined the effects of amphetamine treatment on the expression levels of PSA NCAM and NCAM in mouse hippocampus, cortex and striatum in a context specific behavioral sensitization model. NCAM1 addiction sensitization 17658493 To achieve our goal we examined the effects of amphetamine treatment on the expression levels of PSA NCAM and NCAM in mouse hippocampus, cortex and striatum in a context specific behavioral sensitization model. NCAM1 drug amphetamine 17658493 Immunoblotting analysis demonstrated that acute administration of amphetamine selectively and time dependently decreases the expression of 180 200 kDa isoform of PSA NCAM in hippocampus in both context associated (the Paired) as well as context non associated (the Unpaired) groups. NCAM1 drug amphetamine 17658493 Thus, our results suggest that acute amphetamine administration time dependently decreases the expression of 180 200 kDa isoform of PSA NCAM in mouse hippocampus and PSA NCAM is not involved in amphetamine induced associated learning mechanism.

NCAM1 addiction dependence 17085484 DRD2 and NCAM1 are functional candidate genes for substance dependence; the TTC12 and ANKK1 loci are not well characterized. NCAM1 drug cocaine 16081054 Acute and repeated administration of cocaine differentially regulates expression of PSA NCAM positive neurons in the rat hippocampus. NCAM1 drug cocaine 16081054 Recent data indicating that addictive substances are able to alter brain plasticity and its morphology inclined us to determine whether acute and chronic cocaine administration could modify the expression of a polysialylated form of the neuronal cell adhesion molecule (PSA NCAM) in the dentate gyrus of the rat hippocampus. NCAM1 addiction addiction 16081054 Recent data indicating that addictive substances are able to alter brain plasticity and its morphology inclined us to determine whether acute and chronic cocaine administration could modify the expression of a polysialylated form of the neuronal cell adhesion molecule (PSA NCAM) in the dentate gyrus of the rat hippocampus. NCAM1 drug cocaine 16081054 The number of PSA NCAM immunopositive cells was determined at six time points after cocaine treatment: 6 h and 1, 2, 4, 6, and 10 days (both in acute and repeated treatment). NCAM1 drug cocaine 16081054 It was found that a single injection of cocaine induced a time dependent decrease in the number of PSA NCAM cells in the dentate gyrus. NCAM1 drug cocaine 16081054 In contrast, an increase in the number of PSA NCAM positive cells in the dentate gyrus was observed 2 and 4 days after the last dose of repeated cocaine. NCAM1 drug cocaine 16081054 It is concluded that cocaine can evoke long lasting changes in the PSA NCAM protein expression in the dentate gyrus and that the direction of cocaine induced PSA NCAM changes depends on the regimen of cocaine administration.

NCAM1 drug alcohol 12543998 No significant correlations were detected between ethanol preference and either receptor binding or Drd2 expression; however, a significant correlation was found between preference and Ncam expression. NCAM1 drug nicotine 11978841 It was found that nicotine self administration profoundly decreased, in a dose dependent manner, the expression of PSA NCAM in the DG; a significant effect was observed at all the doses tested (0.02, 0.04, and 0.08 mg/kg per infusion). NCAM1 drug alcohol 10443986 CONTROLLING for age and gender, ANCOVA revealed no differences (p > 0.1) between alcohol dependent and control subjects in leukocyte and lymphocyte subsets or in circulating CD56+ (natural killer) cells. NCAM1 addiction withdrawal 9141423 After 3 months of EtOH withdrawal, PB mononuclear cells (PBMC) from the AWLD group patients still displayed an increased NK cytolytic activity; in addition, the number of PB NK cells (CD3 /CD56+ and CD8 /CD57+) and CD3+/CD56+ PB T cells continued to be increased. NCAM1 drug alcohol 8979026 During the alcohol intake period, the most striking findings were a significant (P < 0.05) expansion of the CD8+ T lymphocyte subset, which coexpresses the activation associated antigens HLA DR and CD11c, as well as a significant increase in both NK cells (CD3 /CD56+) and the T cell subset with NK activity coexpressing CD3 and CD56 (P < 0.05 and P < 0.01, respectively). NCAM1 drug alcohol 8986204 Regarding the alcohol intake period, the most relevant findings were a significant activation of the PB T cell compartment, and specifically of the TCR alpha beta + subset, as reflected by an increased expression of both the HLA DR and CD11c antigens as well as a significant increase of both the PB NK cells (CD3 /CD56+) and the cytotoxic T cells coexpressing the CD3 and CD56 molecules.

MIP drug alcohol 16046875 Macrophage inflammatory protein 2 (MIP 2), a rat ELR+ CXC chemokine, or live Klebsiella pneumoniae (K. pneumoniae) was administered it to induce alveolar neutrophil migration in the absence or presence of acute ethanol intoxication. MIP addiction intoxication 16046875 Macrophage inflammatory protein 2 (MIP 2), a rat ELR+ CXC chemokine, or live Klebsiella pneumoniae (K. pneumoniae) was administered it to induce alveolar neutrophil migration in the absence or presence of acute ethanol intoxication. MIP drug alcohol 16046875 Neutrophil counts were significantly elevated in bronchoalveolar lavage fluid (BALF) of rats receiving IT MIP 2 compared with vehicle treated rats, and this response was significantly decreased in animals pretreated with ethanol. MIP drug alcohol 16046875 CINC IV enhanced the neutrophil response to IT MIP 2 in both the absence and presence of acute ethanol intoxication. MIP addiction intoxication 16046875 CINC IV enhanced the neutrophil response to IT MIP 2 in both the absence and presence of acute ethanol intoxication. MIP drug alcohol 16046875 In rats challenged with K. pneumoniae, ethanol pretreatment significantly reduced BALF levels of CINC and MIP 2, suppressed alveolar neutrophil recruitment, and decreased whole lung myeloperoxidase activity. MIP drug alcohol 16046875 Ethanol significantly inhibits the pulmonary inflammatory responses to both MIP 2 and K. pneumoniae. MIP drug alcohol 14634502 BALF MIP 2 and cytokine induced neutrophil chemoattractant were decreased by alcohol, and BALF from alcohol intoxicated animals had decreased chemotactic activity for neutrophils, as well as a decreased ability to up regulate neutrophil adhesion molecule expression, compared with controls. MIP drug alcohol 14634502 Alcohol also suppressed neutrophil recruitment after intrapulmonary challenge with MIP 2, suggesting that mechanisms other than chemokine suppression contribute to the alcohol induced effect. MIP drug alcohol 12470499 However, ethanol withdrawal + I/R did not significantly alter CINC and MIP 2 production at 3 h of reperfusion. MIP addiction withdrawal 12470499 However, ethanol withdrawal + I/R did not significantly alter CINC and MIP 2 production at 3 h of reperfusion. MIP drug alcohol 12062632 This model correlates closely with alcoholic hepatitis in human beings, characterized by increased IL 8, RANTES (regulated upon activation, normal T cell expressed and secreted), and macrophage inflammatory protein 1 (MIP 1) and profound increases in neutrophils and lymphocytes in the liver. MIP drug alcohol 12045006 Serum ALT, endotoxin, MIP 1alpha, MCP 1 and RANTES, (but not CINC and MIP 2) were also increased in the ethanol fed rats than in the pair fed group. MIP drug alcohol 12045006 Isolated Kupffer cells from ethanol fed rats were primed for enhanced MIP 1alpha, MCP 1, and RANTES production in vitro, while the endothelial cells were primed for enhanced MIP 1alpha release only. MIP drug alcohol 11821656 This study investigated the effects of alcohol on CXC chemokine macrophage inflammatory protein 2 (MIP 2) and cytokine induced neutrophil chemoattractant (CINC) responses in rats challenged with intravenous lipopolysaccharide (LPS). MIP drug alcohol 11821656 Alcohol intoxication suppressed the MIP 2, CINC, and TNFalpha responses in the bloodstream during endotoxemia. MIP addiction intoxication 11821656 Alcohol intoxication suppressed the MIP 2, CINC, and TNFalpha responses in the bloodstream during endotoxemia. MIP drug alcohol 11821656 Alcohol suppressed the up regulation of MIP 2 mRNA expression in all of these organs and CINC mRNA expression in the lungs of rats with endotoxemia. MIP drug alcohol 11598836 Before neutrophil recruitment, bronchoalveolar lavage (BAL) macrophage inflammatory protein 2 (MIP 2) and cytokine induced neutrophil chemoattractant (CINC) were decreased by alcohol. MIP drug alcohol 11598836 MIP 2 and CINC mRNA contents also were suppressed by alcohol 4 and 6 h after infection. MIP drug alcohol 11524180 Thus, this work examined the regulation of chemokines i.e., cytokine induced neutrophil chemoattractant (CINC) and macrophage inflammatory protein 2 (MIP 2) produced by hepatocytes after HIV 1 glycoprotein 120 (gp120) vaccination in Wistar rats fed with ethanol for 30 weeks. MIP drug alcohol 11524180 However, serum CINC and MIP 2 levels were more elevated in the ethanol fed rats than in the pair fed group. MIP drug alcohol 11524180 After HIV 1 gp120 treatment, isolated hepatocytes obtained from the ethanol fed group produced more CINC and MIP 2 than did those of pair fed rats. MIP drug alcohol 11388697 Results show that in vivo ethanol was associated with downregulation of MIP 1alpha and MCP 1 mRNA expression and protein release in primary cultures of Kupffer cells. MIP addiction relapse 11293664 The mRNA for cytokines IL 1beta, IL 6, IL 10 and the chemokines CINC, MIP 1alpha, MCP 1 were significantly (P < 0.05) elevated and persisted for 2 weeks, decreased in 6 weeks and increased again during relapse. MIP drug alcohol 10719799 This work tests the hypotheses that Kupffer cells are a major source of CC chemokines (MIP 1alpha, MCP 1, RANTES) during acute endotoxemia and that acute ethanol intoxication modulates Escherichia coli lipopolysaccharide (LPS, 1 mg/Kg, i.v.)

MIP drug opioid 10654191 In this study, chemotaxis of monkey leukocytes was evaluated using human chemokines IL 8 (interleukin 8), MIP 1 beta and RANTES as the chemoattractants, and the effects of micro opioid receptor agonists, morphine, DAMGO, methadone and endomorphine, on the efficiency of chemotaxis were examined. MIP drug alcohol 10228066 Acute ethanol intoxication inhibited tumor necrosis factor (TNF) alpha and macrophage inflammatory protein (MIP) 2 production in the lung and suppressed the recruitment of neutrophils into the lung. MIP addiction intoxication 10228066 Acute ethanol intoxication inhibited tumor necrosis factor (TNF) alpha and macrophage inflammatory protein (MIP) 2 production in the lung and suppressed the recruitment of neutrophils into the lung. MIP drug alcohol 9347081 In this study, we assessed the effect of alcohol ingestion on the expression of tumor necrosis factor alpha (TNF alpha), and the chemokines macrophage inflammatory protein 2 (MIP 2) and macrophage inflammatory protein 1 alpha (MIP 1 alpha) from murine alveolar macrophages (AMs) cultured ex vivo. MIP drug alcohol 9347081 Two week ethanol feeding resulted in substantial impairment in the lipopolysaccharide (LPS) induced expression of TNF alpha, MIP 2, and MIP 1 alpha mRNA, and protein from LPS stimulated AMs, compared with cytokine production from AMs obtained from CD 1 mice receiving an isocaloric control diet. LY86 addiction relapse 31829430 CBT + MI versus standard care At 12 months, there was no clear difference between treatment groups for numbers lost to treatment (RR 0.99, 95% CI 0.62 to 1.59; participants = 327; studies = 1; low quality evidence), number of deaths (RR 0.60, 95% CI 0.20 to 1.76; participants = 603; studies = 4; low quality evidence), relapse (RR 0.50, 95% CI 0.24 to 1.04; participants = 36; studies = 1; very low quality evidence), or GAF scores (MD 1.24, 95% CI 1.86 to 4.34; participants = 445; studies = 4; very low quality evidence).

ALK drug alcohol 26946429 GABA transmission in ethanol naïve Alk / mice was enhanced at baseline and potentiated in response to acute ethanol application when compared to wild type (Alk +/+) mice. ALK addiction dependence 26946429 These data suggest that ALK plays a role in dependence induced drinking and the regulation of presynaptic GABA release in the CeA.

ALK drug alcohol 26752591 Mice treated with ALK inhibitors drank less ethanol than controls. ALK drug alcohol 26752591 In addition, TAE684 treatment abolished ethanol conditioned place preference, indicating that ALK regulates the rewarding properties of ethanol. ALK drug alcohol 26752591 Because the ventral tegmental area (VTA) is a key brain region involved in the rewarding effects of ethanol, we determined if Alk expression in the VTA is important for binge like ethanol consumption.

ALK drug alcohol 26752591 Mice expressing a short hairpin ribonucleic acid targeting Alk in the VTA drank less ethanol compared with controls. ALK drug alcohol 26752591 Extracellular recordings of putative DA neurons in VTA slices demonstrated that ALK inhibition did not affect the ability of ethanol to stimulate, or DA to inhibit, the firing of DA neurons. ALK drug alcohol 26752591 These data support the possibility that ALK might be a novel target of pharmacotherapy for reducing excessive alcohol consumption. ALK addiction relapse 26646246 ALK fusion was neither a risk factor nor protective factor in relapse free survival and overall survival. ALK drug nicotine 26646246 Male, current smoker, and EML4 ALK variant 3 indicated poor prognosis among ALK fusion positive lung adenocarcinomas. ALK drug alcohol 26206265 MDK and one of its receptors, anaplastic lymphoma kinase (ALK), also regulate behavioral responses to ethanol in mice. ALK drug alcohol 26206265 The goal of this study was to determine whether MDK and ALK expression and signaling are activated by ethanol. ALK drug alcohol 26206265 We found that ethanol treatment of neuroblastoma cells increased MDK and ALK expression. ALK drug alcohol 26206265 We also assessed activation of ALK by ethanol in cells and found that ALK and ALK dependent extracellular signal regulated kinase (ERK) and signal transducer and activator of transcription 3 (STAT3) phosphorylation increased rapidly with ethanol exposure. ALK drug alcohol 26206265 Similarly, treatment of cells with recombinant MDK protein increased ALK, ERK and STAT3 phosphorylation, suggesting that ethanol may utilize MDK to activate ALK signaling. ALK drug alcohol 26206265 In support of this, transfection of cells with MDK siRNAs attenuated ALK signaling in response to ethanol. ALK drug alcohol 26206265 We found that inhibition of ALK or knockout of MDK attenuated ethanol induced ERK phosphorylation in mouse amygdala. ALK drug alcohol 26206265 These results demonstrate that ethanol engages MDK and ALK signaling, which has important consequences for alcohol induced neurotoxicity and the regulation of behaviors related to alcohol abuse.

SIRT1 drug cocaine 25698746 To determine the mechanisms by which SIRT1 mediates cocaine induced plasticity in NAc, we used chromatin immunoprecipitation followed by massively parallel sequencing (ChIP seq), 1 d after 7 daily cocaine (20 mg/kg) or saline injections, to map SIRT1 binding genome wide in mouse NAc. SIRT1 drug cocaine 25698746 First, despite its induction in NAc, chronic cocaine causes depletion of SIRT1 from most affected gene promoters in concert with enrichment of H4K16ac (itself a deacetylation target of SIRT1), which is associated with increased expression of these genes.

SIRT1 drug cocaine 23499958 Resveratrol is known as an activator of SIRT1, which leads to the deacetylation of histone and non histone protein substrates, but also has other pharmacological profiles such as the inhibition of monoamine oxidase (MAO) A and MAO B. Resveratrol was previously demonstrated to potentiate the rewarding effects of chronic cocaine via activation of SIRT1. SIRT1 drug cocaine 22729177 We found that impairment of Agouti related protein (AgRP) circuitry by either Sirt1 knockdown in AgRP expressing neurons or early postnatal ablation of these neurons increased exploratory behavior and enhanced responses to cocaine. SIRT1 drug alcohol 19951294 Flies harboring deletions of the genes encoding the olfactory co receptor Or83b or the sirtuin Sir2 showed marked changes in the development of ethanol tolerance. SIRT1 drug cocaine 19447090 The findings also provide comprehensive insight into the molecular pathways regulated by cocaine including a new role for sirtuins (Sirt1 and Sirt2) which are induced in the nucleus accumbens by cocaine and, in turn, dramatically enhance the behavioral effects of the drug.

VIP drug alcohol 17960055 The effect of binge fetal alcohol exposure on the number of vasoactive intestinal peptide producing neurons in fetal sheep brain. VIP addiction intoxication 17960055 The effect of binge fetal alcohol exposure on the number of vasoactive intestinal peptide producing neurons in fetal sheep brain. VIP drug alcohol 17960055 We hypothesized that early fetal alcohol exposure alters the number of fetal neurons expressing vasoactive intestinal peptide (VIP), a potent cerebral vasodilator. VIP drug alcohol 17960055 We hypothesized that early fetal alcohol exposure alters the number of fetal neurons expressing vasoactive intestinal peptide (VIP), a potent cerebral vasodilator. VIP drug alcohol 17960055 Alcohol exposed fetal sheep brains had fewer VIP immunopositive neurons per hemisphere, 14.6 x 10(6), compared to saline controls, 19.8 x 10(6). VIP drug alcohol 17960055 The total neuron number was not different, 1.19 x 10(9) versus 1.23 x 10(9) respectively, indicating a selective decrease in VIP neurons as a result of alcohol exposure. VIP drug alcohol 17960055 In sheep, alcohol exposure early in gestation is associated with fewer VIP producing neurons later in gestation compared to saline controls; therefore, alcohol related changes in the number of VIP expressing neurons may be responsible in part for the attenuated hypoxic cerebral vasodilation described in fetal and neonatal sheep exposed to alcohol earlier in gestation. VIP drug alcohol 15834231 Vasoactive intestinal peptide and corticotropin releasing hormone increase beta endorphin release and proopiomelanocortin messenger RNA levels in primary cultures of hypothalamic cells: effects of acute and chronic ethanol treatment. VIP drug alcohol 15834231 Furthermore, the authors studied the effects of acute and chronic treatment with ethanol on the response of beta EP neurons to VIP and CRH. VIP drug alcohol 15834231 Acute treatment with ethanol increased beta EP neuronal gene expression and the secretory response to CRH and VIP. VIP drug alcohol 15834231 However, previous exposure to chronic ethanol reduced the CRH and VIP responses of these neurons. VIP drug alcohol 15834231 These results indicate that VIP and CRH stimulate beta EP release from hypothalamic cells in primary cultures and that the stimulatory and adaptive responses of beta EP neurons to ethanol may involve alteration in the responsiveness of beta EP secreting neurons to CRH and VIP. VIP drug alcohol 15520530 It has been previously shown that withdrawal from alcohol decreases the synthesis and expression of vasopressin (VP) and vasoactive intestinal polypeptide (VIP) in the suprachiasmatic nucleus (SCN), and that the infusion of NGF over 1 month completely restores these changes.

VIP drug opioid 12480163 However, VIP (1 microM) and the delta opioid selective agonist, [D Pen(2,5)] enkephalin (DPDPE; 1 microM), in combination, manifest a striking facilitative interaction to augment spinal levels of cAMP. VIP drug opioid 12480163 Facilitative interactions between VIP and kappa or mu opioids were of a reduced magnitude or not observed, respectively. VIP drug opioid 12480163 Blockade of delta opioid or VIP receptors using naltrindole or VIP6 28, respectively antagonized the VIP DPDPE facilitative interaction, as did pertussis toxin treatment. VIP drug opioid 12480163 This suggests that modulation of Ca(2+) trafficking by VIP and delta opioid agonists is a point of convergence of their respective signal transduction cascades, the concomitant action at which achieves cytosolic Ca(2+) concentrations that are now sufficient for the activation of signaling molecules, e.g. VIP drug opioid 12409215 On the grounds of our previous studies with vasoactive intestinal polypeptide (VIP), it appears that different receptors are involved in the effects of PACAP in acute and chronic morphine actions. VIP drug alcohol 11709626 In ethanol treated and withdrawn rats, NGF produced increases in the number of AVP and VIP immunostained neurons to values identical to those of controls.

TDO2 drug amphetamine 26259827 Tph2 gene deletion enhances amphetamine induced hypermotility: effect of 5 HT restoration and role of striatal noradrenaline release. TDO2 addiction addiction 26259827 Variants of tryptophan hydroxylase 2 (Tph2), the gene encoding enzyme responsible for the synthesis of brain serotonin (5 HT), have been associated with neuropsychiatric disorders, substance abuse and addiction. TDO2 drug amphetamine 26259827 This study assessed the effect of Tph2 gene deletion on motor behavior and found that motor activity induced by 2.5 and 5 mg/kg amphetamine was enhanced in Tph2( / ) mice. TDO2 drug amphetamine 26259827 Using the in vivo microdialysis technique we found that the ability of amphetamine to stimulate noradrenaline (NA) release in the striatum was reduced by about 50% in Tph2( / ) mice while the release of dopamine (DA) was not affected. TDO2 drug amphetamine 26259827 The role of endogenous 5 HT in enhancing the effect of amphetamine was confirmed showing that treatment with the 5 HT precursor 5 hydroxytryptophan (10 mg/kg) restored tissue and extracellular levels of brain 5 HT and the effects of amphetamine on striatal NA release and motor activity in Tph2( / ) mice. TDO2 drug amphetamine 26259827 Treatment with the NA precursor dihydroxyphenylserine (400 mg/kg) was sufficient to restore the effect of amphetamine on striatal NA release and motor activity in Tph2( / ) mice. TDO2 drug amphetamine 26259827 Here, we show that deletion of Tph2, the gene responsible for brain 5 HT synthesis, enhances the motor effect of amphetamine in mice through the inhibition of striatal NA release.

TDO2 drug cocaine 26013962 Two hundred twenty participants (126 cocaine users, 94 controls) were assessed with visuospatial, spatial, and verbal WM tasks, genotyped for the length polymorphism in the promoter region of the 5 HTT (5 HTTLPR), the variable number of tandem repeats in the second intron of the 5 HTT (VNTR In2), two single nucleotide polymorphisms (rs4570625 and rs1386497) in the tryptophan hydroxylase 2 (TPH2) gene and quantified for peripheral 5 HTT mRNA expression in whole blood samples. TDO2 drug cocaine 26013962 Several significant gene × environment interactions between 5 HT genotypes and cocaine use on WM emerged: in cocaine users, the long/long (5 HTTLPR), 9+10/9+10 (VNTR In2) and C/C (TPH2 rs1386497) genotypes were risk alleles for WM impairments, whereas in healthy controls these polymorphisms were associated with improved WM performance. TDO2 drug alcohol 23995203 Studies investigating suicide, alcohol related suicide and the rate limiting enzyme of serotonin synthesis, tryptophan hydroxylase 2 (TPH2), remain to date rather limited. TDO2 drug alcohol 23995203 Recent studies of TPH2 showed a range of strong, mild or no association with suicide and alcohol related suicide, depending on a study group and genetic variants tested.

LPP drug alcohol 31547662 To further validate the LPP model, umbrella sampling was used to calculate ethanol permeability in comparison with experiment (log(P) values obtained from modeling the SC's multiple LPP layers are 7.6 and 6.6 cm/s, and that from experiment on cadaver skin is 6.65 cm/s). LPP drug nicotine 30824792 Unlike previous studies, there were no differences between male and female smokers with regard to LPP responses to cigarette related images. LPP drug cannabinoid 29737034 Cannabis cue elicited modulation of the 1000 to 3000 milliseconds LPP was larger in high DI users at post stressor only, although the effect was only robust in the 1000 to 2000 milliseconds window.

LPP drug nicotine 29065198 Analyses of P300 and LPP responses to GHWLs suggest that disgust focused images interfere with the EEG indexed attentional processing of smoking cues and do so better than health anxiety focused messages. LPP drug nicotine 28275830 Prior to treatment randomization, smokers (N = 180) in a placebo controlled trial using bupropion and varenicline completed event related potential recording (late positive potential, LPP) while viewing pleasant (P), cigarette (C) related, and other pictures. LPP drug cocaine 28245173 In this study we used the late positive potential (LPP) to investigate whether such increased attention bias toward drug related relative to non drug related cues changes over a protracted period of reduced drug use in treatment seeking individuals with a cocaine use disorder (CUD). LPP addiction relapse 28245173 In this study we used the late positive potential (LPP) to investigate whether such increased attention bias toward drug related relative to non drug related cues changes over a protracted period of reduced drug use in treatment seeking individuals with a cocaine use disorder (CUD). LPP drug cocaine 28245173 The results showed a reversal in attention bias (i.e., LPP amplitude) from baseline (i.e., drug > pleasant) to follow up (i.e., pleasant > drug) driven by an increased attentional engagement with pleasant pictures; this LPP reversal was paralleled by a concomitant reduction in self reported wanting and craving for cocaine in the CUD group. LPP addiction relapse 28245173 The results showed a reversal in attention bias (i.e., LPP amplitude) from baseline (i.e., drug > pleasant) to follow up (i.e., pleasant > drug) driven by an increased attentional engagement with pleasant pictures; this LPP reversal was paralleled by a concomitant reduction in self reported wanting and craving for cocaine in the CUD group. LPP addiction relapse 28245173 Results collectively indicate that, by tracking with drug abstinence, LPP in response to drug related relative to pleasant cues may serve as an indicator of clinical progress in treatment seeking individuals with CUD.

LPP drug nicotine 27277662 The objective of the present study is to investigate the association between smoking relapse and resumption and ERPs reflecting smoking cue reactivity (i.e., P300, LPP), inhibitory control (i.e., N2, P3), and error processing (i.e., error related negativity (ERN), Pe). LPP addiction relapse 27277662 The objective of the present study is to investigate the association between smoking relapse and resumption and ERPs reflecting smoking cue reactivity (i.e., P300, LPP), inhibitory control (i.e., N2, P3), and error processing (i.e., error related negativity (ERN), Pe). LPP drug nicotine 27141838 We tested whether individual differences in brain responses to cigarette related and pleasant stimuli require a long history of smoking to develop by measuring the late positive potential (LPP) to cigarette cues, emotional, and neutral stimuli in 45 young, light smokers (ages 18 25). LPP addiction intoxication 25915691 The current study examines the relation between symptoms of depression, binge drinking, and the magnitude of early (early posterior negativity, EPN) and later (P3 and late positive potential, LPP) visual processing components of affectively negative, positive, and neutral visual stimuli. LPP drug alcohol 25915691 Results of repeated measures analyses of variance (ANOVAs; Depression × Binge × Emotion × Laterality) showed that binge drinkers exhibited lower LPP amplitudes for negative images, compared with nonbinge drinkers, regardless of depression, consistent with motivational models of alcohol abuse. LPP addiction intoxication 25915691 Results of repeated measures analyses of variance (ANOVAs; Depression × Binge × Emotion × Laterality) showed that binge drinkers exhibited lower LPP amplitudes for negative images, compared with nonbinge drinkers, regardless of depression, consistent with motivational models of alcohol abuse. LPP addiction intoxication 25915691 Otherwise, differences across depressed and nondepressed groups were largest among binge drinkers, including a pattern of stronger early attentional engagement (EPN) to negative and neutral images, but decreased later processing (P3 and LPP) across all emotional categories, consistent with a vigilance avoidance response pattern. LPP drug opioid 25867962 Previous research has suggested that the late positive potential (LPP) of heroin users is increased by heroin related stimuli because of the attention grabbing nature of such stimuli. LPP drug opioid 25385024 Treatment with MORE was associated with significant increases in LPP response to natural reward stimuli relative to neutral stimuli which were correlated with enhanced positive affective cue responses and reductions in opioid craving from pre to post treatment. LPP addiction relapse 25385024 Treatment with MORE was associated with significant increases in LPP response to natural reward stimuli relative to neutral stimuli which were correlated with enhanced positive affective cue responses and reductions in opioid craving from pre to post treatment. LPP addiction reward 25385024 Treatment with MORE was associated with significant increases in LPP response to natural reward stimuli relative to neutral stimuli which were correlated with enhanced positive affective cue responses and reductions in opioid craving from pre to post treatment. LPP drug cannabinoid 24913137 Response to emotional and cannabis associated visual stimuli was assessed using self report, event related potentials (using the late positive potential [LPP]), facial electromyography and skin conductance response. LPP drug cannabinoid 24913137 Reduced LPP response to pleasant stimuli was predictive of more frequent subsequent cannabis use (β = 0.24, p = 0.034). LPP drug cannabinoid 24913137 The LPP captures a reward processing deficit in patients with SSD and shows potential as a biomarker for identifying patients at risk of heavy cannabis use.

LPP drug nicotine 24065931 Smokers were assigned to two groups (IRS+/IRS ) based on the amplitude of the late positive potential (LPP) component to the pictures, a neural marker of motivational salience. LPP drug nicotine 24065931 Smokers (n = 42) with blunted brain responses to intrinsically rewarding (pleasant) pictures and enhanced responses to cigarette pictures were assigned to the IRS group, while smokers (n = 62) with the opposite pattern of LPP responding were assigned to the IRS+ group. LPP drug opioid 23723052 In this study, we compared the effect of thienorphine with morphine on long term potentiation (LTP) in the lateral perforant path (LPP) granule cell synapse of the rat dentate gyrus (DG). LPP drug opioid 23723052 Chronic thienorphine treatment facilitated LTP in the LPP DG cell synapses more than chronic morphine treatment. LPP drug nicotine 23643564 The late positive potential (LPP) in response to varying types of emotional and cigarette stimuli in smokers: a content comparison. LPP drug nicotine 23643564 We recorded ERPs from 180 smokers prior to their participation in a smoking cessation clinical trial and assessed emotional salience by measuring the amplitude of the late positive potential (LPP; 400 to 600 ms after picture onset). LPP drug nicotine 23643564 However, unlike emotional pictures, no difference was noted for the LPP between cigarette stimuli containing people versus those containing only objects, suggesting that in contrast to emotional objects, cigarette related objects are highly relevant for smokers. LPP drug nicotine 22087333 Early and late LPP components in response to passively viewed neutral and smoking pictures were compared with LPPs in response to smoking pictures that were reappraised with three different reappraisal strategies. LPP drug nicotine 22087333 Results show that when smokers actively imagine how pleasant it would be to smoke (pleasant condition), their early LPP in response to smoking cues increases, but when smokers actively focus on an alternative stimulus (distraction condition) or think of a rational, uninvolved interpretation of the situation (rational condition), smoking related late LPP amplitude decreases to the processing level of neutral stimuli. LPP drug nicotine 22087333 Present results are the first to indicate that smoking cue elicited LPP amplitudes can be modulated by cognitive strategies, suggesting that attentive processing of smoking cues can be intentionally regulated by smokers with various levels of dependence. LPP addiction dependence 22087333 Present results are the first to indicate that smoking cue elicited LPP amplitudes can be modulated by cognitive strategies, suggesting that attentive processing of smoking cues can be intentionally regulated by smokers with various levels of dependence. LPP drug nicotine 21967530 Cluster analysis was used to assign smokers to two groups based on the amplitude of the late positive potential (LPP) to the experimental stimuli. LPP drug cocaine 21450043 In particular, the late positive potential (LPP) appears to be enhanced following cocaine related compared with neutral stimuli in human participants with cocaine use disorders (CUD). LPP drug cocaine 21450043 Cocaine pictures elicited increased electrocortical measures of motivated attention in ways similar to affectively pleasant and unpleasant pictures in all CUD, an effect that was no longer discernible during the late LPP window for the current users. LPP drug cocaine 18331370 In abstinent cocaine dependent patients and a healthy control group, we studied the late positive potential (LPP) amplitudes elicited by neutral and cocaine related stimuli. LPP drug cocaine 18331370 The results show that cocaine dependent patients have an enhanced electrophysiological response in the late LPP time window to cocaine related stimuli as compared to controls, suggesting an enhanced processing of these stimuli. LPP drug cocaine 18331370 Most importantly, a robust association was observed between cocaine craving and LPP amplitude. LPP addiction relapse 18331370 Most importantly, a robust association was observed between cocaine craving and LPP amplitude. LPP addiction relapse 18331370 High craving levels were associated with larger LPP amplitudes at central electrode sites in the right hemisphere. LPP drug alcohol 14561117 For those in the alcohol groups, negative targets behaving positively elicited the largest LPP and recall responses. LPP drug opioid 11701207 Experiments were performed to investigate the effects of acute and chronic intracerebroventricular (icv) morphine infusions via osmotic minipumps on long term potentiation (LTP) in the lateral perforant path (LPP) granule cell synapse of the rat dentate gyrus. LPP drug opioid 11701207 LTP induction was significantly attenuated after acute morphine infusion (1 h) in LPP granule cell synapses of the dentate gyrus. LPP drug opioid 11701207 These results suggest a difference between the effects of acute and chronic intracerebroventricular morphine infusions on synaptic plasticity in the LPP granule cell synapses of the dentate gyrus. IL1RN drug cannabinoid 32714224 ii) Nominally significant differences were observed in the levels of IL 1RA (p = 0.0059), YKL40 (p = 0.0069), CatS (p = 0.013), sTNFR1 (p = 0.031), and BDNF (p = 0.020), where these factors exhibited higher plasma levels in Cannabis user SCZ patients than in non users. IL1RN drug alcohol 31854009 C57BL/6J male and female mice were provided a 2 bottle choice of alcohol at increasing concentrations (3, 6, 9, and 12%, 4 days each) or water, and some were treated with daily injections of an NLRP3 inhibitor (MCC950), a caspase 1 inhibitor (VX765), IL 1 receptor antagonist (IL 1ra; anakinra), or vehicle injection. IL1RN drug alcohol 31854009 Treatment with VX765, MCC950, and IL 1ra significantly reduced alcohol consumption and preference in female mice (p < 0.05). IL1RN drug alcohol 31854009 Treatment with MCC950 and IL 1ra reduced alcohol consumption, while IL 1ra reduced alcohol preference in male mice (p < 0.05).

IL1RN drug alcohol 31736187 Dampened IL 1ra and IL 6 in response to stress was observed as a function of alcohol dependence and not moderated by depressive symptoms. IL1RN addiction dependence 31736187 Dampened IL 1ra and IL 6 in response to stress was observed as a function of alcohol dependence and not moderated by depressive symptoms. IL1RN drug alcohol 30791967 Overall, we found that IL 1β expression is significantly increased in microglia and neurons of Dep compared to Non Dep and naïve mice, IL 1β and IL 1ra bi directionally modulate GABA transmission through both pre and postsynaptic mechanisms in all three groups, and IL 1β and IL 1ra do not alter the facilitation of GABA release induced by acute ethanol.

IL1RN drug alcohol 28090151 Within 2 hours of alcohol intake, levels of IL 1Ra were elevated and remained so throughout the assessment period (p for trend = 0.015). IL1RN drug alcohol 26365025 Bilateral infusions of IL 1 receptor antagonist (IL 1Ra) reduced ethanol consumption when infused into the BLA but not the CeA. IL1RN drug alcohol 26365025 These observations were specific to ethanol drinking as the IL 1Ra did not alter either sucrose drinking or open field locomotor activity. IL1RN drug alcohol 25839897 Gene expression studies identified the interleukin 1 receptor type I (IL 1R1) as part of a pathway associated with a genetic predisposition to high alcohol consumption, and lack of the endogenous IL 1 receptor antagonist (IL 1ra) strongly reduced ethanol intake in mice. IL1RN drug alcohol 25839897 Here, we compared ethanol mediated behaviors in mice lacking Il1rn or Il1r1. IL1RN drug alcohol 25839897 Deletion of Il1rn (the gene encoding IL 1ra) increases sensitivity to the sedative/hypnotic effects of ethanol and flurazepam and reduces severity of acute ethanol withdrawal.

IL1RN drug alcohol 25582105 Kupffer cells and IL 1β were required for the hepatic iNKT accumulation, as either blocking IL 1β signaling with a recombinant IL 1 receptor antagonist (IL 1Ra), depleting Kupffer cells by clodronate liposomes, or specifically silencing IL 1β in Kupffer cells by nanoparticle encapsulated siRNA, resulted in inhibited hepatic iNKT cell accumulation and activation, as well as amelioration of alcoholic fatty liver.

IL1RN drug nicotine 10792346 Soluble interleukin 1 receptor antagonist concentration in patients with Graves' ophthalmopathy is neither related to cigarette smoking nor predictive of subsequent response to glucocorticoids. IL1RN drug nicotine 10792346 The aim of the present study was to evaluate serum soluble interleukin 1 receptor antagonist (sIL 1RA) concentration and its relationship with the degree of cigarette smoking in patients with Graves' ophthalmopathy (GO). IL1RN drug nicotine 10792346 Our study suggests that circulating soluble interleukin 1 receptor antagonist levels, both at baseline and during glucocorticoid treatment, are neither influenced by cigarette smoking nor predictive of subsequent response to glucocorticoid treatment. IL1RN drug alcohol 9895030 This study examines i) the activity of serum prolyl endopeptidase (PEP) and dipeptidlyl peptidase IV (DPP IV) in detoxified alcohol dependent patients without liver disease versus normal controls, and ii) the relationships between serum DPP IV and PEP activity and the production of cytokines or cytokine receptors, such as interleukin 6 (IL 6), tumor necrosis factor alpha (TNF alpha), interferon y (IFN y), IL 1 receptor antagonist (IL 1RA), and IL 10, and granulocyte macrophage colony stimulatory factor (GM CSF). HMGB1 drug opioid 32733481 (d) Opioid receptor agonists induce the production of high mobility group box 1 (HMGB1), an endogenous TLR4 agonist, supporting intercellular (neuron to glia or glia to neuron) interactions. HMGB1 drug opioid 32733481 (d) Opioid receptor agonists induce the production of high mobility group box 1 (HMGB1), an endogenous TLR4 agonist, supporting intercellular (neuron to glia or glia to neuron) interactions. HMGB1 drug alcohol 32588826 Ethanol consumption leads to activation of neuroimmune signaling in the central nervous system through many types of Toll like receptors (TLRs), as well as the release of their endogenous agonists (HMGB1 protein, S100 protein, heat shock proteins, extracellular matrix breakdown proteins). HMGB1 drug opioid 31879851 Chronic morphine mediated upregulation of high mobility group box 1 in the spinal cord contributes to analgesic tolerance and hyperalgesia in rats. HMGB1 drug opioid 31879851 We examined whether spinal high mobility group box 1 (HMGB1) is involved in morphine tolerance and its underlying mechanisms by using a model of repeated intrathecal (i.t.) HMGB1 drug opioid 31879851 We examined whether spinal high mobility group box 1 (HMGB1) is involved in morphine tolerance and its underlying mechanisms by using a model of repeated intrathecal (i.t.) HMGB1 drug opioid 31879851 morphine exposure led to increased expression of HMGB1, Toll like receptor 4 (TLR4), and receptor for advanced glycation end products (RAGE) and their mRNAs in the dorsal horn. HMGB1 drug opioid 31879851 Morphine challenge also promoted HMGB1 expression and release in cultured spinal neurons, but these effects were inhibited by TAK 242, naloxone (antagonists of TLR4), and TLR4 siRNA. HMGB1 drug opioid 31879851 Intrathecal coadministration of morphine with TAK 242 or PDTC (inhibitor of NF κB activation) also reduced HMGB1 expression in the spinal cord. HMGB1 drug opioid 31879851 coinjections of morphine with glycyrrhizin (GL, an HMGB1 inhibitor) or HMGB1 siRNA prevented reduction of the maximal possible analgesic effect (MPAE) of morphine and alleviated morphine withdrawal induced hyperalgesia. HMGB1 addiction withdrawal 31879851 coinjections of morphine with glycyrrhizin (GL, an HMGB1 inhibitor) or HMGB1 siRNA prevented reduction of the maximal possible analgesic effect (MPAE) of morphine and alleviated morphine withdrawal induced hyperalgesia. HMGB1 drug opioid 31879851 injections of GL or HMGB1 antibody started at day 7 of morphine injection. HMGB1 drug opioid 31879851 injections of morphine with HMGB1 siRNA inhibited the activation of NF κB, but not that of JNK and p38. HMGB1 drug opioid 31879851 Together, these results suggest that morphine mediated upregulation of spinal HMGB1 contributes to analgesic tolerance and hyperalgesia via activation of TLR4/NF κB signaling, and the HMGB1 inhibitor might be a promising adjuvant to morphine in the treatment of intractable pain in the clinic. HMGB1 drug alcohol 31666409 The effects of acute (single) and chronic ethanol administration on the level of pro inflammatory cytokines (IL 1β and TNF α), as well as on the level of mRNA NF κB, TLR4 and its endogenous agonist, HMGB1 protein, were investigated in rats.

HMGB1 drug alcohol 26695754 Ethanol exposure activates signaling pathways featuring high mobility group box 1 and Toll like receptor 4 (TLR4), resulting in induction of the transcription factor nuclear factor kappa light chain enhancer of activated B cells, which regulates expression of several cytokine genes involved in innate immunity, and its target genes. HMGB1 drug alcohol 25816800 HMGB1 has been implicated in the pathophysiology of several neuroinflammatory conditions including ischemia, traumatic brain injury, seizure and chronic ethanol use. HMGB1 addiction sensitization 25816800 In light of recent evidence suggesting that HMGB1 may also mediate stress induced sensitization of neuroinflammatory responses, mechanisms of HMGB1 action in neuroinflammatory priming are explored. HMGB1 drug alcohol 25787746 Studies from our laboratory employing reverse transcription polymerase chain reaction (RT PCR) to assess mRNA, immunohistochemistry and Western blot analysis to assess protein expression, and others suggest that ethanol increases brain neuroimmune gene and protein expression through two distinct mechanisms involving (1) systemic induction of innate immune molecules that are transported from blood to the brain and (2) the direct release of high mobility group box 1 (HMGB1) from neurons in the brain.

HMGB1 drug alcohol 25787746 Expression of HMGB1, TLRs, and other ISMs is increased several fold in the human orbital frontal cortex, and expression of these molecules is highly correlated with each other as well as lifetime alcohol consumption and age of drinking onset. HMGB1 drug alcohol 25787746 The persistent and cumulative nature of alcohol on HMGB1 and TLR gene induction support their involvement in alcohol induced long term changes in brain function and neurodegeneration. HMGB1 drug alcohol 25486089 Using wild type (WT) and TLR4 deficient (TLR4 KO) adolescent mice treated intermittently with ethanol (3.0g/kg) for 2weeks, we show that binge like ethanol treatment activates TLR4 signaling pathways (MAPK, NFκB) leading to the up regulation of cytokines and pro inflammatory mediators (COX 2, iNOS, HMGB1), impairing synaptic and myelin protein levels and causing ultrastructural alterations.

HMGB1 drug alcohol 25175868 In addition, HMGB1 TLR4 and innate immune NF κB target genes are increased leading to persistent and sensitized neuroimmune responses to ethanol and other agents that release HMGB1 or directly stimulate TLR receptors and/or NMDA receptors. HMGB1 drug alcohol 24551070 Release of neuronal HMGB1 by ethanol through decreased HDAC activity activates brain neuroimmune signaling. HMGB1 drug alcohol 24551070 We previously found increased HMGB1 in post mortem alcoholic human brain as well as in ethanol treated mice and rat brain slice cultures. HMGB1 drug alcohol 24551070 The present study investigated the mechanisms for ethanol induced release of HMGB1 and neuroimmune activation in a model of rat hippocampal entorhinal cortex (HEC) brain slice cultures. HMGB1 drug alcohol 24551070 Ethanol exposure triggered dose dependent HMGB1 release, predominantly from neuronal cells. HMGB1 drug alcohol 24551070 Similarly, ethanol treatment was found to induce the translocation of HDAC1/4 and HMGB1 proteins from nuclear to cytosolic fractions. HMGB1 drug alcohol 24551070 Furthermore, ethanol treatment reduced HDAC1/4 mRNA and increased acetylated HMGB1 release into the media. HMGB1 drug alcohol 24551070 These results suggest decreased HDAC activity may be critical in regulating acetylated HMGB1 release from neurons in response to ethanol. HMGB1 drug alcohol 24551070 Ethanol and HMGB1 treatment increased mRNA expression of proinflammatory cytokines TNFα and IL 1β as well as toll like receptor 4 (TLR4). HMGB1 drug alcohol 24551070 Targeting HMGB1 or microglial TLR4 by using siRNAs to HMGB1 and TLR4, HMGB1 neutralizing antibody, HMGB1 inhibitor glycyrrhizin and TLR4 antagonist as well as inhibitor of microglial activation all blocked ethanol induced expression of proinflammatory cytokines TNFα and IL 1β. HMGB1 drug alcohol 24551070 These results support the hypothesis that ethanol alters HDACs that regulate HMGB1 release and that danger signal HMGB1 as endogenous ligand for TLR4 mediates ethanol induced brain neuroimmune signaling through activation of microglial TLR4. HMGB1 drug alcohol 23895427 The cytokine mRNA increase induced by withdrawal from chronic ethanol in the sterile environment of brain is mediated by CRF and HMGB1 release. HMGB1 addiction withdrawal 23895427 The cytokine mRNA increase induced by withdrawal from chronic ethanol in the sterile environment of brain is mediated by CRF and HMGB1 release. HMGB1 addiction withdrawal 23895427 Therefore, the hypothesis is tested that release of an endogenous TLR4 agonist, high mobility group box 1 (HMGB1) and/or corticotropin releasing factor (CRF) during CE withdrawal are responsible for CE protocols increasing cytokine mRNAs. HMGB1 addiction withdrawal 23895427 Therefore, the hypothesis is tested that release of an endogenous TLR4 agonist, high mobility group box 1 (HMGB1) and/or corticotropin releasing factor (CRF) during CE withdrawal are responsible for CE protocols increasing cytokine mRNAs. HMGB1 addiction withdrawal 23895427 To test whether HMGB1 and/or CRF support the CE withdrawal increase in cytokine mRNAs, the HMGB1 antagonists, glycyrrhizin and ethyl pyruvate, and a CRF1 receptor antagonist (CRF1RA) are administered during 24 hours of CE withdrawal. HMGB1 addiction withdrawal 23895427 While chronic LPS had no effect on HMGB1 mRNA, withdrawal from CE protocols significantly elevated HMGB1 mRNA. HMGB1 addiction withdrawal 23895427 Systemic administration of HMGB1 antagonists or a CRF1RA significantly reduced the cytokine mRNA increase following CE withdrawal. HMGB1 addiction withdrawal 23895427 The CRF1RA and the HMGB1 antagonist, ethyl pyruvate, also reduced the HMGB1 mRNA increase that followed CE withdrawal. HMGB1 addiction withdrawal 23895427 By blocking HMGB1 or CRF action during CE withdrawal, evidence is provided that HMGB1 and CRF release are critical for the CE withdrawal induction of selected brain cytokine mRNAs. HMGB1 addiction intoxication 23867237 This manuscript tested the hypothesis that adolescent binge drinking upregulates RAGE and Toll like receptor (TLR) 4 as well as their endogenous agonist, high mobility group box 1 (HMGB1). HMGB1 addiction intoxication 23867237 This manuscript tested the hypothesis that adolescent binge drinking upregulates RAGE and Toll like receptor (TLR) 4 as well as their endogenous agonist, high mobility group box 1 (HMGB1). HMGB1 drug alcohol 23867237 Adolescent intermittent ethanol exposure also increased TLR4 and HMGB1 expression at P56 that persisted into young adulthood (P80). HMGB1 drug alcohol 23867237 Together, these human and animal data support the hypothesis that an early age of drinking onset upregulates RAGE/TLR4 HMGB1 and other neuroimmune genes that persist into young adulthood and could contribute to risk of alcoholism or other brain diseases associated with neuroinflammation. HMGB1 drug alcohol 23206318 High mobility group box 1/Toll like receptor danger signaling increases brain neuroimmune activation in alcohol dependence. HMGB1 addiction dependence 23206318 High mobility group box 1/Toll like receptor danger signaling increases brain neuroimmune activation in alcohol dependence. HMGB1 drug alcohol 23206318 We investigated expression of HMGB1, TLR2, TLR3, and TLR4 in chronic ethanol treated mouse brain, postmortem human alcoholic brain, and rat brain slice culture to test the hypothesis that neuroimmune activation in alcoholic brain involves ethanol activation of HMGB1/TLR danger signaling. HMGB1 drug alcohol 23206318 Ethanol treatment of mice increased brain mRNA and +IR protein expression of HMGB1, TLR2, TLR3, and TLR4. HMGB1 drug alcohol 23206318 Postmortem human alcoholic brain also showed increased HMGB1, TLR2, TLR3, and TLR4 +IR cells that correlated with lifetime alcohol consumption, as well as each other. HMGB1 drug alcohol 23206318 Ethanol treatment of brain slice culture released HMGB1 into the media and induced the proinflammatory cytokine, interleukin 1 beta (IL 1β). HMGB1 drug alcohol 23206318 Neutralizing antibodies to HMGB1 and small inhibitory mRNA to HMGB1 or TLR4 blunted ethanol induction of IL 1β. HMGB1 drug alcohol 23206318 Ethanol induced HMGB1/TLR signaling contributes to induction of the proinflammatory cytokine, IL 1β. HMGB1 drug alcohol 23206318 Increased expression of HMGB1, TLR2, TLR3, and TLR4 in alcoholic brain and in mice treated with ethanol suggests that chronic alcohol induced brain neuroimmune activation occurs through HMGB1/TLR signaling. HMGB1 addiction intoxication 22986167 Adolescent binge drinking increases expression of the danger signal receptor agonist HMGB1 and Toll like receptors in the adult prefrontal cortex. HMGB1 drug alcohol 22986167 Recent studies have found that ethanol increases neuroinflammation via upregulated high mobility group box 1 (HMGB1) signaling through Toll like receptors (TLRs).

HMGB1 drug alcohol 22709825 Ethanol potentiation of poly I:C was associated with ethanol increased expression of TLR3 and endogenous agonist HMGB1 in the brain. HMGB1 drug alcohol 22709825 Ethanol potentiation of TLR3 agonist responses is consistent with priming microglia monocytes and increased NOX, ROS, HMGB1 TLR3 and markers of neurodegeneration.

F10 drug alcohol 16633972 We performed a retrospective analysis of clinical data and ECG's from patients discharged between 1995 and 2005 with the diagnosis of DT (ICD Code F10.4) or alcohol withdrawal seizures (F10.3). F10 addiction withdrawal 16633972 We performed a retrospective analysis of clinical data and ECG's from patients discharged between 1995 and 2005 with the diagnosis of DT (ICD Code F10.4) or alcohol withdrawal seizures (F10.3). F10 drug alcohol 15082461 22 drug free, detoxified patients (15 men, seven women) aged between 27 and 58 (mean 41.5 +/ 8.1) years, diagnosed as alcohol dependent (ICD 10: F10.23) were included in the study. F10 drug alcohol 14505267 A disproportionately large number of those in somatic wards, mainly internal medicine wards, were in the diagnostic categories F13 (medication dependency), F10 (alcohol related), F0 09 (cerebral organic disorders) and F40 48 (neurotic disorders). F10 drug alcohol 14505267 On the internal medicine wards the second most common diagnostic group in the age group 16 64 years, after ischaemic heart disease (I25), was alcohol related disorders (F10). F10 drug alcohol 11042866 To study the influence of alcohol and psychosocial variables on delinquent behavior, we coded data from the psychiatric evaluation of 254 defendants using a standardized score sheet, analyzing correlations between acute intoxication at the time of the crime (ICD 10:F10.0), diagnosis of alcohol dependency according to ICD 10 (F10.2), psycho biographical variables, criminal history, and parameters relating to the index offence.

F10 drug alcohol 10619208 According to the diagnoses of the primary care physicians, 7.4% of the residents had mental and behavioural disorders due to alcohol (ICD 10: F10). F10 drug alcohol 9340658 The main substance was alcohol (F10.1 or F10.2; 52.2%), followed by cannabis (F12; 25%), opiates (F11; 4.1%), sedatives or hypnotics (F13; 2.7%) and cocaine (F16; 0.5%). F10 drug cannabinoid 9340658 The main substance was alcohol (F10.1 or F10.2; 52.2%), followed by cannabis (F12; 25%), opiates (F11; 4.1%), sedatives or hypnotics (F13; 2.7%) and cocaine (F16; 0.5%). F10 drug cocaine 9340658 The main substance was alcohol (F10.1 or F10.2; 52.2%), followed by cannabis (F12; 25%), opiates (F11; 4.1%), sedatives or hypnotics (F13; 2.7%) and cocaine (F16; 0.5%). DBCN drug nicotine 31316930 The numbers of the doublecortin (DCX) positive cells and 5 bromo 2' deoxyuridine (BrdU) positive cells in the dentate gyrus were suppressed in the nicotine withdrawal rats, in contrast, treadmill running enhanced the numbers of DCX positive cells and BrdU positive cells. DBCN addiction withdrawal 31316930 The numbers of the doublecortin (DCX) positive cells and 5 bromo 2' deoxyuridine (BrdU) positive cells in the dentate gyrus were suppressed in the nicotine withdrawal rats, in contrast, treadmill running enhanced the numbers of DCX positive cells and BrdU positive cells. DBCN drug cannabinoid 31162770 Our results show that a 6 day repeated temozolomide treatment (25 mg/kg/day), a chemotherapy drug that blocks hippocampal neurogenesis, prevented cannabidiol induced increment in the early stages of neuronal maturation and differentiation, without altering the basal levels of BrdU/NeuN and doublecortin immunostaining. DBCN drug opioid 30728362 Further, we demonstrate that the μ opioid receptor (MOR) is expressed on DG NSCs and that MSA leads to a two fold elevation of endogenous MOR levels in doublecortin expressing (DCX+) NSC progenies in the rat DG. DBCN drug opioid 30447281 Removal of microglial specific MyD88 signaling alters dentate gyrus doublecortin and enhances opioid addiction like behaviors. DBCN addiction addiction 30447281 Removal of microglial specific MyD88 signaling alters dentate gyrus doublecortin and enhances opioid addiction like behaviors. DBCN drug opioid 30447281 Furthermore, morphine treated Cretg/0 mice showed increased doublecortin (DCX) signal relative to Cre0/0 control mice in the hippocampus, indicative of increased number of immature neurons. DBCN drug nicotine 30391635 Impaired neurogenesis, as shown by reduction in the expression of the endogenous cell proliferation marker Ki67 and the early neuron marker doublecortin, was also associated with nicotine abstinence. DBCN drug alcohol 29449568 Alcohol exposure reduced the number of both NeuN positive and doublecortin positive cells in the hippocampus. DBCN drug opioid 27078155 Using cell type selective markers, we observed that morphine reduced the number of late stage progenitors and immature neurons such as Doublecortin (DCX) and βIII Tubulin (TuJ1) positive cells in the SGZ but did not reduce the number of early progenitors such as Nestin, SOX2, or neurogenic differentiation 1 (NeuroD1) positive cells. DBCN drug amphetamine 26366944 The results showed that METH caused a decrease in neuronal phenotypes as determined by the expressions of nestin, doublecortin (DCX) and beta III tubulin while causing an increase in glial fibrillary acidic protein (GFAP) expression. DBCN drug cannabinoid 25944409 These changes included proteins involved in impulsivity like behavior, synaptic plasticity, and cannabinoid signaling modulation, such as alpha synuclein, phosphatase 1 alpha, doublecortin like kinase 2, and diacylglycerol kinase zeta, and were validated by immunoblotting. DBCN drug alcohol 25729346 Using a rodent model of adolescent intermittent ethanol (AIE; 5.0 g/kg, i.g., 20% EtOH w/v; 2 days on/2 days off from postnatal day [P]25 to P55), we discovered that AIE treatment reduced neurogenesis (i.e., doublecortin immunoreactive [DCX + IR] cells) in both the dorsal and ventral hippocampal dentate gyrus of late adolescent (P56) male Wistar rats that persisted during abstinence into adulthood (P220). DBCN drug cocaine 25294309 Overall level of neurogenesis, as detected by the S phase marker 5' bromo 2' deoxyuridine (BrdU) and the immature neuron marker doublecortin (DCX), was unaltered by cocaine conditioning. DBCN drug amphetamine 25201326 Moreover, METH (10nM) increased doublecortin (DCX) protein levels consistent with neuronal differentiation. DBCN drug alcohol 23844726 Increased proliferation was followed by a 75% increase in doublecortin expression and a 56% increase in surviving bromodeoxyuridine labeled cells 14 and 35 days post ethanol exposure, respectively. DBCN addiction withdrawal 23844726 Although these results mirror the magnitude of reactive neurogenesis described in adult rat studies, ectopic bromodeoxyuridine and doublecortin positive cells were detected in the molecular layer and hilus of adolescent rats displaying severe withdrawal symptoms, an effect that has not been described in adults. DBCN drug alcohol 23567812 Quantitative analyses of immunoreactivity revealed a significant reduction in measures of neurogenesis, progenitor proliferation, as indexed by doublecortin (DCX), Ki67, and increased markers of cell death as indexed by cleaved caspase 3, and Fluoro Jade at 72 days, and decreases in DCX, and increases in cleaved caspase 3 at 114 days in the ethanol vapor exposed rats. DBCN drug opioid 23213573 Increases in doublecortin immunoreactivity in the dentate gyrus following extinction of heroin seeking behavior. DBCN addiction relapse 23213573 Increases in doublecortin immunoreactivity in the dentate gyrus following extinction of heroin seeking behavior. DBCN addiction relapse 23213573 We investigated the effects of extinction of drug seeking behavior on the formation of immature neurons in the DG as assessed by quantification of doublecortin (DCX) immunoreactivity. DBCN drug opioid 22487733 Surprisingly, methadone did not alter any of three quantified parameters relevant to adult hippocampal neurogenesis (number of Ki67 , doublecortin , or BrdU immunoreactive cells [BrdU given prior to saline/methadone exposure]). DBCN addiction reward 22340086 When measured 24 hours following the CPP test, there was no effect of EtOH on doublecortin (DCX) expression or Fluoro Jade B staining. DBCN drug opioid 22079577 Here, we show that two commonly used post operative buprenorphine dosing regimes significantly inhibit the proliferation of doublecortin positive neuroblasts but not other hippocampal stem and progenitor cell populations in adult mice. DBCN drug opioid 22079577 Buprenorphine, administered in schedules of three 0.05 mg/kg subcutaneous injections over a single day or seven 0.05 mg/kg injections over a 3 day period decreased the number of actively proliferating 5 iodo 2' deoxyuridine labeled doublecortin positive cells for up to 6 days after opiate withdrawal. DBCN addiction withdrawal 22079577 Buprenorphine, administered in schedules of three 0.05 mg/kg subcutaneous injections over a single day or seven 0.05 mg/kg injections over a 3 day period decreased the number of actively proliferating 5 iodo 2' deoxyuridine labeled doublecortin positive cells for up to 6 days after opiate withdrawal. DBCN drug alcohol 19554644 After 4 days of binge alcohol exposure, neurogenesis was decreased by 33 and 28% at 0 and 2 days after the last dose according to doublecortin expression. DBCN addiction intoxication 19554644 After 4 days of binge alcohol exposure, neurogenesis was decreased by 33 and 28% at 0 and 2 days after the last dose according to doublecortin expression. DBCN drug benzodiazepine 19437554 Phenobarbital and clonazepam significantly inhibited cell proliferation by 63% and 59%, respectively, and doublecortin immunoreactivity (indicator of neurogenesis) in the dorsal hippocampus was also significantly decreased by 26% and 24%, respectively. DBCN drug cocaine 18322096 Unexpectedly, CSA WD and CSA CONT resulted in more immature doublecortin immunopositive (+) neurons in the posterior SGZ and a normal number of adult generated BrdU+ neurons in the SGZ, suggesting an enduring impact of CSA regardless of whether cocaine intake was stopped or continued. DBCN drug psychedelics 16949621 We used 5' bromo 2 deoxyuridine (BrdU) and Ki 67 as mitotic markers, and doublecortin (DCX) as a marker of immature neurons, to study proliferation, survival and maturation of adult generated cells in the dentate gyrus (DG) of the hippocampus following binge administration of MDMA (8 injections of 5 mg/kg at 6 h intervals). DBCN addiction intoxication 16949621 We used 5' bromo 2 deoxyuridine (BrdU) and Ki 67 as mitotic markers, and doublecortin (DCX) as a marker of immature neurons, to study proliferation, survival and maturation of adult generated cells in the dentate gyrus (DG) of the hippocampus following binge administration of MDMA (8 injections of 5 mg/kg at 6 h intervals). RPS6KB1 drug alcohol 32333810 Phosphorylation levels of 4E BP1 and p70 S6K were also increased following alcohol exposure. RPS6KB1 drug alcohol 31733664 Results also showed that alcohol use was associated with a general reduction in Akt/mTOR signaling via several phosphoproteins (IR, IRS1, IGF1R, PTEN, ERK, mTOR, p70S6K, RPS6) in multiple brain regions including hippocampus and entorhinal cortex. RPS6KB1 drug psychedelics 31128500 However, no changes in the p70S6K, PSD 95, GluA1, and synapsin immunocontents were found in the hippocampus of ketamine plus guanosine treated mice. RPS6KB1 drug opioid 30146703 We examined the effects of chronic treatment of morphine and/or methadone in the presence or absence of metformin with or without AMPK inhibitor (dorsomorphin hydrochloride) on levels of nitric oxide and cyclic adenosine monophosphate (cAMP), phosphorylated and dephosphorylated ribosomal protein S6 kinase β 1 (S6K1) and 4E binding protein 1 (4E BP1) in T98G cells. RPS6KB1 drug amphetamine 29574227 Behaviorally, METH sensitized mice possessed increased levels of phosphorylated mTOR/S2448 and its down stream regulator p70S6K and pS6 in the ventral striatum. RPS6KB1 drug alcohol 29457836 Chronic plus binge ethanol feeding led to hyperactivation of mTORC1, as evidenced by increased phosphorylation of mTOR and its downstream kinase S6 kinase 1 (S6K1) in hepatocytes. RPS6KB1 addiction intoxication 29457836 Chronic plus binge ethanol feeding led to hyperactivation of mTORC1, as evidenced by increased phosphorylation of mTOR and its downstream kinase S6 kinase 1 (S6K1) in hepatocytes. RPS6KB1 drug alcohol 29457836 Chronic plus binge ethanol feeding led to activation of SREBP 1 and lipin 1 through S6K1 dependent and independent mechanisms. RPS6KB1 addiction intoxication 29457836 Chronic plus binge ethanol feeding led to activation of SREBP 1 and lipin 1 through S6K1 dependent and independent mechanisms. RPS6KB1 drug cocaine 28432301 We found that exposure to drug related cues reinstated cocaine seeking behavior and increased AMPK and p70s6k phosphorylation in the NAc core but not shell. RPS6KB1 addiction relapse 28432301 We found that exposure to drug related cues reinstated cocaine seeking behavior and increased AMPK and p70s6k phosphorylation in the NAc core but not shell. RPS6KB1 drug alcohol 26373814 Ethanol + NNK had synergistic stimulatory effects on 8 iso PGF 2α, inhibitory effects on p p70S6K, tau and p tau and trend effects on insulin like growth factor type 1 (IGF 1) receptor expression and phosphorylation. RPS6KB1 addiction intoxication 25257868 The stimulation induced increase in the phosphorylation of S6K1 Thr(421)/Ser(424) (20 52%), S6K1 Thr(389) (45 57%), and its substrate rpS6 Ser(240/244) (37 72%) was blunted by EtOH at 30 min, 4 h, and 12 h. Phosphorylation of 4E BP1 Ser(65) was also attenuated by EtOH (61%) at 4 h. Conversely, phosphorylation of extracellular signal regulated kinase Thr(202)/Tyr(204) was increased by stimulation in Control and EtOH mice at 30 min but only in Control at 4 h. Our data indicate that acute EtOH intoxication suppresses muscle protein synthesis for at least 12 h and greatly impairs contraction induced changes in synthesis and mTOR signaling. RPS6KB1 drug nicotine 24916432 The initiation of nicotine induced locomotor sensitization was accompanied by the increased phosphorylated level of mTORC1 downstream target proteins including p p70s6k and p 4EBP in the BLA, but not CeA. RPS6KB1 addiction sensitization 24916432 The initiation of nicotine induced locomotor sensitization was accompanied by the increased phosphorylated level of mTORC1 downstream target proteins including p p70s6k and p 4EBP in the BLA, but not CeA. RPS6KB1 drug nicotine 24916432 Increased p p70s6k and p 4EBP were also observed in the expression of nicotine sensitization, which was demonstrated to be inhibited by systemic rapamycin administration. RPS6KB1 addiction sensitization 24916432 Increased p p70s6k and p 4EBP were also observed in the expression of nicotine sensitization, which was demonstrated to be inhibited by systemic rapamycin administration. RPS6KB1 drug cocaine 24595501 Using a mouse model of conditioned place preference, regulation of the activity of glycogen synthase kinase 3 (GSK3), mammalian target of Rapamycin complex 1 (mTORC1), P70S6K, β catenin, and the upstream signaling molecule Akt, was studied in cortico limbic striatal circuitry after re exposure to an environment previously paired with cocaine. RPS6KB1 drug cocaine 24595501 Levels of phosporylated Akt Thr308, GSK3α Ser21, GSK3β Ser9, mTORC1, and P70S6K were reduced in the nucleus accumbens and hippocampus 10 min after the reactivation of cocaine cue memories. RPS6KB1 drug cannabinoid 23727505 This study evaluated the status of cannabinoid (CB) CB1 and CB2 receptors, the endocytic cycle of CB1 receptors, G protein coupled receptor regulatory kinases (GRK), and associated signaling (mammalian target of rapamicin (mTOR) and 70kDa ribosomal protein S6 kinase (p70S6K)) in brain cortices of drug abusers and cocaine and cannabinoid treated rodents. RPS6KB1 drug cocaine 23727505 This study evaluated the status of cannabinoid (CB) CB1 and CB2 receptors, the endocytic cycle of CB1 receptors, G protein coupled receptor regulatory kinases (GRK), and associated signaling (mammalian target of rapamicin (mTOR) and 70kDa ribosomal protein S6 kinase (p70S6K)) in brain cortices of drug abusers and cocaine and cannabinoid treated rodents. RPS6KB1 drug cannabinoid 23727505 Rimonabant and AM281 also behaved as inverse agonists on the activation of mTOR and its target p70S6K. RPS6KB1 drug cocaine 23727505 Chronic cocaine in mice was associated with tolerance to the acute activation of mTOR and p70S6K. RPS6KB1 drug cocaine 23727505 In long term cocaine addicts, mTOR and p70S6K activations were not altered when compared with controls, indicating that CB1 receptor signaling was dampened. RPS6KB1 drug cocaine 23727505 The dysregulation of CB1 receptor, GRK2/3/5, and mTOR/p70S6K signaling by cocaine may contribute to alterations of neuroplasticity and/or neurotoxicity in brains of cocaine addicts. RPS6KB1 drug cocaine 20861369 We found that exposure to a cocaine related cue induced reinstatement to cocaine seeking and increased phosphorylation of p70s6 kinase (p70s6k) and ribosomal protein s6 (rps6), measures of mTOR activity, in the nucleus accumbens (NAc) core but not shell. RPS6KB1 addiction relapse 20861369 We found that exposure to a cocaine related cue induced reinstatement to cocaine seeking and increased phosphorylation of p70s6 kinase (p70s6k) and ribosomal protein s6 (rps6), measures of mTOR activity, in the nucleus accumbens (NAc) core but not shell. RPS6KB1 drug cocaine 20861369 Furthermore, inhibition of NAc core but not shell p70s6k and rps6 phosphorylation by rapamycin decreased cue induced reinstatement of cocaine seeking. RPS6KB1 addiction relapse 20861369 Furthermore, inhibition of NAc core but not shell p70s6k and rps6 phosphorylation by rapamycin decreased cue induced reinstatement of cocaine seeking. RPS6KB1 addiction relapse 20861369 Finally, stimulation of NAc core p70s6k and rps6 phosphorylation by NMDA enhanced cue induced reinstatement, an effect reversed by rapamycin pretreatment. RPS6KB1 drug opioid 20826199 Here, we tested the role of PI3K/Akt mTOR p70S6K signaling pathway in morphine induced CPP in the hippocampus. RPS6KB1 addiction reward 20826199 Here, we tested the role of PI3K/Akt mTOR p70S6K signaling pathway in morphine induced CPP in the hippocampus.

RPS6KB1 addiction reward 20826199 Likewise, levels of phosphorylated mTOR and p70S6K were significantly enhanced in the CA3 following morphine CPP. RPS6KB1 drug alcohol 18317950 Differential phosphorylation of translation initiation regulators 4EBP1, S6k1, and Erk 1/2 following inhibition of alcohol metabolism in mouse heart. RPS6KB1 drug alcohol 18317950 The purpose of the present set of experiments was designed to examine the effects of inhibitors of ethanol metabolism on the phosphorylation of 4E binding protein (4EBP1) and S6k1(Thr(389)), two factors regulating mRNA translation initiation. RPS6KB1 drug alcohol 18317950 Phosphorylation of 4E BP1, S6k1(Thr(389)), and Erk 1/2 was reduced 2 h following IP injection of alcohol. RPS6KB1 drug alcohol 18317950 Pretreatment with 4 methylpyrazole (4 MP), an inhibitor of alcohol dehydrogenase (ADH), did not attenuate the ethanol induced decrease in phosphorylation of 4EBP1 and S6k1(Thr(389)). RPS6KB1 drug alcohol 18317950 Pretreatment with cyanamide, an inhibitor of aldehyde dehydrogenase, did not attenuate the ethanol induced decrease in phosphorylation S6k1(Thr(389)), but partially prevented the ethanol induced lowering of 4EBP1 phosphorylation. RPS6KB1 drug amphetamine 15837117 The aim of the present study was to investigate the role of p70 S6 kinase (p70 S6K) phosphorylation, which contributes to the selective translation of a unique family of mRNA, in mediating both the METH induced rewarding effect and its sensitization. RPS6KB1 addiction sensitization 15837117 The aim of the present study was to investigate the role of p70 S6 kinase (p70 S6K) phosphorylation, which contributes to the selective translation of a unique family of mRNA, in mediating both the METH induced rewarding effect and its sensitization. RPS6KB1 drug amphetamine 15837117 pre injection with 0.025 pmol/rat of a selective p70 S6K inhibitor rapamycin failed to affect the METH induced conditioned place preference. RPS6KB1 drug alcohol 15547464 Alcohol intoxication impairs phosphorylation of S6K1 and S6 in skeletal muscle independently of ethanol metabolism. RPS6KB1 addiction intoxication 15547464 Alcohol intoxication impairs phosphorylation of S6K1 and S6 in skeletal muscle independently of ethanol metabolism. RPS6KB1 drug alcohol 15547464 The purpose of this study was to characterize the ability of alcohol to suppress insulin like growth factor (IGF) I stimulation of ribosomal S6 kinase 1 (S6K1) and 4E BP1 phosphorylation, which are central elements in the signal transduction pathway used to coordinate the protein synthetic response and may contribute to the development of alcoholic myopathy. RPS6KB1 drug alcohol 15547464 In contrast, IGF I failed to stimulate S6K1 or S6 phosphorylation 2.5 hr after intraperitoneal administration of alcohol when the blood alcohol concentration was increased between approximately 165 and 300 mg/dl. RPS6KB1 drug alcohol 15547464 With a maximal suppressive dose of alcohol, the inhibitory effect on S6K1/S6 phosphorylation was observed as early as 1 hr and for up to 8 hr. RPS6KB1 drug alcohol 15547464 The ability of alcohol to impair phosphorylation of S6K1 and S6 was independent of gender (male versus female), nutritional status (fed versus fasted), and route of alcohol administration (intraperitoneal versus oral). RPS6KB1 drug alcohol 15547464 The direct effect of alcohol on IGF stimulated S6K1/S6 phosphorylation was also present when the isolated hindlimb was perfused in situ with buffer containing alcohol. RPS6KB1 drug alcohol 15547464 In contrast to S6K1, acute alcohol intoxication did not consistently impair the ability of IGF I to stimulate 4E BP1 phosphorylation under any of the experimental conditions. RPS6KB1 addiction intoxication 15547464 In contrast to S6K1, acute alcohol intoxication did not consistently impair the ability of IGF I to stimulate 4E BP1 phosphorylation under any of the experimental conditions. RPS6KB1 drug alcohol 15547464 These data indicate that acute alcohol intoxication selectively impairs IGF I signaling via S6K1, but not 4E BP1, and that this defect is independent of gender, nutritional state, route of administration, and alcohol metabolism. RPS6KB1 addiction intoxication 15547464 These data indicate that acute alcohol intoxication selectively impairs IGF I signaling via S6K1, but not 4E BP1, and that this defect is independent of gender, nutritional state, route of administration, and alcohol metabolism. RPS6KB1 drug alcohol 12944322 Alcohol impairs leucine mediated phosphorylation of 4E BP1, S6K1, eIF4G, and mTOR in skeletal muscle. RPS6KB1 drug alcohol 12944322 Hence, ethanol produces a leucine resistance in skeletal muscle, as evidenced by the impaired phosphorylation of 4E BP1, eIF4G, S6K1, and mTOR, that is independent of elevations in endogenous glucocorticoids. RPS6KB1 drug alcohol 12658115 IGF I induced phosphorylation of S6K1 and 4E BP1 in heart is impaired by acute alcohol intoxication. RPS6KB1 addiction intoxication 12658115 IGF I induced phosphorylation of S6K1 and 4E BP1 in heart is impaired by acute alcohol intoxication. RPS6KB1 drug alcohol 12376318 Alcohol impairs insulin and IGF I stimulation of S6K1 but not 4E BP1 in skeletal muscle. PROC drug nicotine 30978583 We evaluated cross lagged panel models for negative affect and smoking using PROC CALIS in SAS. PROC drug cocaine 23770647 In a generalized linear mixed model (SAS Proc Glimmix), cocaine use varied by time of day relative to business hours (p<0.0001) and there was a significant interaction between Day of the Week and Time Relative to Business Hours (p<0.002) regardless of current work status.

PAL addiction addiction 29606223 The current study addresses this need, offering outcome data from the first longitudinal, comparative study of 12 step groups and their alternatives: The Peer ALlternatives for Addiction (PAL) Study. PAL drug amphetamine 28889212 NE preferring releasers were approximately 13 fold more potent for NE compared to dopamine release and ranged in potency for serotonin release (PAL 329 < l methamphetamine < PAL 169). PAL drug amphetamine 28889212 Among the "NE preferring" releasers, PAL 329 and l methamphetamine also dose dependently substituted for cocaine but differed in potency.

In discrimination studies, both compounds dose dependently increased cocaine like responding but with different potencies (cocaine=methcathinone >PAL 434). PAL drug cocaine 23768644 Chronic treatment with methcathinone or PAL 434 dose dependently and selectively reduced cocaine self administration. PAL drug cocaine 23768644 PAL 434 was about 4 fold and methcathinone about 1.6 fold more potent at decreasing cocaine over food maintained responding.

OXT drug cannabinoid 30521833 The hormone oxytocin (OXT) modulates stress and may have therapeutic efficacy for substance use disorders, but few studies have examined OXT in cannabis users. OXT drug cannabinoid 30521833 oxytocin (OXT; 40 IU) administration on stress reactivity (using the Trier Social Stress Test; TSST) and cannabis (5.6% THC) self administration was assessed in recreational cannabis using men (n = 31) and women (n = 32) relative to i.n. OXT drug cannabinoid 30521833 These results suggest that OXT administration may lead to greater stress reactivity in recreational cannabis users, particularly women, and support growing evidence that sex differences should be carefully considered when examining the therapeutic potential of OXT.

OXT drug alcohol 26282397 Because oxytocin (OXT) and vasopressin (AVP) contribute to rewarding social behavior, the present study utilized a genetic strategy to determine whether OXT and AVP receptors (OXTR, AVPR1a) are essential for female mice to demonstrate a conditioned social preference for ethanol. OXT drug opioid 25225634 To better understand the opioid OXT interplay in the central nervous system, we first determined the expression of the oxytocin receptor (OXTR) in the brain of WT C57BL6/J mice by quantitative autoradiography; we then evaluated OXTR regional alterations in Oprm1 ( / ) mice.

NR4A2 addiction withdrawal 24706046 Furthermore, during morphine dependence, Nurr1 was detected in the nucleus compartment of VTA TH positive neurons, whereas Pitx3 was strongly detected in the nucleus of TH positive neurons after single morphine administration and during morphine withdrawal. NR4A2 addiction addiction 24706046 Present data provide novel insight into the potential correlation between Nurr1 and Pitx3 and DA neurons plasticity during opiate addiction in the mesolimbic pathway. NR4A2 drug opioid 23783774 Furthermore, a meta analysis of the common striatal DEGs in this study along with morphine regulated striatal transcriptomes in mice (National Center for Biotechnology Information Gene Expression Omnibus Database Accession Code GSE7762) suggested similar expression profiles of genes involved in neuronal development (e.g., Bhlhe22, Nr4a2). NR4A2 drug nicotine 23562942 The Nr4a family member, nr4a2/nurr1, showed increased striatal expression after all three drug treatments, while striatal nr4a3/nor 1 expression was increased by the drug combination whereas NAc nr4a1/nurr77 was decreased by nicotine and the drug combination. NR4A2 drug nicotine 23562942 The Nr4a family member, nr4a2/nurr1, showed increased striatal expression after all three drug treatments, while striatal nr4a3/nor 1 expression was increased by the drug combination whereas NAc nr4a1/nurr77 was decreased by nicotine and the drug combination. NR4A2 addiction addiction 23215787 Alterations in transcription factors that regulate the development and maintenance of dopamine (DA) neurons (such as Nurr1 and Pitx3) play an important role in the pathogenesis of addiction diseases. NR4A2 drug opioid 23215787 We have examined the effects of acute and chronic morphine and morphine withdrawal on TH expression and activity as well as expression of Nurr1, Pitx3 and Ago2 in the ventral tegmental area (VTA) and nucleus accumbens (NAc) of the rat. NR4A2 addiction withdrawal 23215787 We have examined the effects of acute and chronic morphine and morphine withdrawal on TH expression and activity as well as expression of Nurr1, Pitx3 and Ago2 in the ventral tegmental area (VTA) and nucleus accumbens (NAc) of the rat. NR4A2 drug opioid 23215787 Acute morphine produced a marked increase in TH activity and DA turnover in the NAc, concomitantly with increased Nurr1 and Pitx3 expression in the VTA. NR4A2 drug opioid 23215787 The combined decrease in Ago2 and increases in Nurr1 and Pitx3 might represent some of the mechanisms that served to protect against accumbal TH regulation observed in morphine withdrawn rats, which may be critical for DA bioavailability to influence behaviour.

NR4A2 drug amphetamine 21547080 Moreover, toxic METH doses caused decreases in the expression of the dopamine developmental factors, Shh, Lmx1b, and Nurr1, but not in the levels of Otx2 and Pitx3, in saline pretreated rats. NR4A2 drug amphetamine 21547080 METH pretreatment followed by METH challenges also decreased Nurr1 but increased Otx2 and Pitx3 expression in the midbrain. NR4A2 drug amphetamine 21229349 Unexpectedly, acute METH challenge to METH pretreated animals caused further decreases in Nr4a2 (Nurr1) mRNA levels. NR4A2 drug amphetamine 21229349 Unexpectedly, acute METH challenge to METH pretreated animals caused further decreases in Nr4a2 (Nurr1) mRNA levels. NR4A2 drug amphetamine 21151937 Decreased level of Nurr1 in heterozygous young adult mice leads to exacerbated acute and long term toxicity after repeated methamphetamine exposure. NR4A2 drug amphetamine 21151937 In this study, we examined the synergistic effects of repeated early exposure to methamphetamine in adolescence and reduction in Nurr1 gene levels. NR4A2 drug nicotine 20659174 We have, therefore, analysed the association of six single nucleotide polymorphisms (SNPs) within the three genes belonging to the NR4A orphan nuclear receptor family, NR4A1 (rs2603751, rs2701124), NR4A2 (rs12803, rs834835) and NR4A3 (rs1131339, rs1405209), with the degree of smoking in a sample of 204 unrelated schizophrenia patients, which included 126 smokers and 78 non smokers. NR4A2 drug opioid 20560679 This study aimed to investigate the associations between response to methadone maintenance treatment (MMT) and polymorphisms in genes coding for the OPRM1 opioid receptor, the metabotropic glutamate receptors GRM6 and GRM8, the nuclear receptor NR4A2, the photolyase enzyme cryptochrome 1 (CRY1), and the transcription factor myocardin (MYOCD), which have previously been associated with the risk of opioid dependence disorder.

NR4A2 drug amphetamine 18930103 mRNA expression of the Nurr1 and NGFI B nuclear receptor families following acute and chronic administration of methamphetamine. NR4A2 drug amphetamine 18930103 One to three hours after 4 mg/kg acute methamphetamine (METH) administration, the levels of Nurr1 mRNA were significantly higher in the prelimbic (PrL), primary motor (M1) and primary somatosensory (S1) cortices and ventral tegmental area (VTA), as compared with the basal level. NR4A2 drug amphetamine 18930103 Pretreatment with 0.5 mg/kg of SCH23390 prevented the acute METH induced increase in Nurr1 mRNA levels in these brain regions. NR4A2 drug amphetamine 18930103 After the saline challenge, the group chronically exposed to METH displayed significantly higher levels of Nurr1 mRNA in the PrL, S1 and VTA, and of NGFI B mRNA in the PrL, M1, S1, striatum and AcbC than did the group chronically treated with saline. NR4A2 drug amphetamine 18930103 The groups chronically exposed to METH failed to increase Nurr1 mRNA in the VTA, and NGFI B mRNA in the AcbC, when challenged with 4 mg/kg METH. NR4A2 drug amphetamine 18930103 These results suggest that Nurr1 and NGFI B mRNA play differential roles upon exposure to METH.

NR4A2 drug opioid 18057194 We examined mRNA expression levels of DA transporter (DAT), tyrosine hydroxylase (TH), dopamine D2 receptor, alpha synuclein, and nuclear receptor related 1 (Nurr1) in discrete mesocorticolimbic and nigrostriatal subpopulations of heroin users and control subjects. NR4A2 drug opioid 18057194 Moreover, the results revealed an exaggerated reduction of Nurr1 expression with age in heroin users (r = 0.8268, p < 0.001 vs controls, r = 0.6204, p = 0.0746). NR4A2 drug opioid 18057194 Altogether the current findings provide direct neurobiological evidence that midbrain reward circuits have the most prominent DA and opioid impairments in human heroin abusers and that abnormal Nurr1 transcription with opiate use may exacerbate limbic dysfunction with age.

NR4A2 drug cocaine 17070804 We show that chronic, but not acute or subchronic, cocaine administration downregulates Nurr1 and Pitx3 transcripts whereas En1 transcripts are upregulated.

NR4A2 addiction reward 12814373 We have investigated the impact of heterozygous deletion of Nurr1 on ethanol consumption in adult mice as a model for drug induced reward and on wheel running as a model for natural reward. NR4A2 drug alcohol 12814373 Interestingly, Nurr1 heterozygous mice never developed high ethanol consumption nor did they develop as much running behaviour as did the wild type animals. NR4A2 drug alcohol 12814373 Thus, Nurr1 appears to have a key role for the reinforcing properties of ethanol and running that underlies the development of excessive reward seeking behaviours characteristic for addiction.

NR4A2 drug alcohol 12814373 Quantitative trait loci mapping using C57Bl/6 and DBA/2 mice describe a locus for ethanol preference on chromosome 2, wherein Nurr1 is located. NR4A2 drug alcohol 12814373 We found two dinucleotide repeats in the Nurr1 promoter that were longer in mice with low preference for ethanol (DBA/2 and 129/Sv) than in mice with high preference for ethanol (C57Bl/6J and C57Bl/6NIH). NR4A2 drug alcohol 12814373 These sequential data are compatible with Nurr1 as a candidate gene responsible for the quantitative trait loci for ethanol preference on mouse chromosome 2. NR4A2 drug alcohol 12814373 Together, our data thus imply involvement of Nurr1 in the transition to a state of high ethanol consumption as well as in the development of a high amount of wheel running in mice.

IL5 addiction intoxication 29317484 Repeated pairings of adolescent rats to binge concentrations of toluene vapor previously shown to enhance dopamine release in reward sensitive areas of the brain produced CPP that persisted for 7 but not 30 d. Toluene induced CPP was associated with increased excitability of IL5/6 mPFC neurons projecting to the core of the NAc and reduced excitability of those projecting to the NAc shell.

IL5 addiction sensitization 21602845 After sensitization and challenge with rDer p2, mice that were fed with total protein extracted from transgenic plants showed decreases in serum Der p2 specific IgE and IgG1 titers, decreased IL 5 and eotaxin levels in bronchial alveolar lavage fluid, and eosinophil infiltration in the airway. IL5 drug alcohol 21421450 Serum IL 5 levels were decreased in both alcoholic groups. IL5 drug opioid 17974159 In contrast, IL 5 levels stimulated by PHA showed a significant increase in both groups, while no significant effect of naloxone could be observed. IL5 drug opioid 14741432 We had previously shown that chronic morphine treatment in vivo and in vitro decreases IL 2 and IFNgamma (Th1) protein levels and increases IL 4 and IL 5 (Th2) protein levels in a time dependent manner. IL5 drug opioid 14741432 In addition in this paper, we show that chronic morphine treatment resulted in a decrease in IFNgamma and IL 2 mRNA and an increase in IL 4 and IL 5 mRNA accumulation in murine splenocytes.

HAL drug amphetamine 27624149 HAL also decreased the salience of gambling words after AMPH. HAL drug amphetamine 26032742 We have previously shown that chronic haloperidol (HAL) treatment reduces amphetamine (AMPH) induced locomotor activity in AMPH sensitized rats, but only when paired with high levels of the estrogen, 17 β estradiol. HAL drug amphetamine 26032742 The aim of the current study was to assess this interaction by investigating the effects of estradiol, AMPH and HAL on brain volume changes in awake female rats. HAL drug amphetamine 25823912 HAL treated rats were dopamine supersensitive, as indicated by sensitization to systemic AMPH induced potentiation of both locomotor activity and operant responding for a conditioned reward (CR).

HAL addiction reward 25823912 In HAL treated rats, inhibition of the NAc also failed to disrupt systemic AMPH induced potentiation of operant responding for CR. HAL drug amphetamine 25823912 Furthermore, while intra NAc AMPH enhanced locomotion in both HAL treated and control animals, inhibition of the NAc disrupted systemic AMPH induced locomotion only in control rats. HAL addiction withdrawal 24464874 The present study explored the impact of withdrawal from repeated haloperidol (HAL) treatment, as well as the response to a novel α5 gamma aminobutyric acid (GABA(A)) receptor positive allosteric modulator (α5PAM), on the activity of the DA system in the methylazoxymethanol acetate (MAM) neurodevelopmental model of schizophrenia. HAL addiction withdrawal 24464874 Electrophysiological recordings were conducted from DA neurons in the ventral tegmental area of MAM and saline (SAL) rats following 7 day withdrawal from repeated HAL (21 d, 0.6 mg/kg, orally). HAL drug amphetamine 24464874 SAL rats withdrawn from HAL demonstrated reduced spontaneous DA neuron activity along with an enhanced locomotor response to amphetamine, indicative of the development of DA supersensitivity. HAL addiction withdrawal 24464874 Both α5PAM treatment and ventral hippocampal (vHPC) inactivation reversed the DA neuron depolarization block following HAL withdrawal in SAL rats. HAL drug amphetamine 24464874 In contrast, MAM rats withdrawn from HAL exhibited reduced spontaneous DA activity and enhanced locomotor response to amphetamine compared with untreated SAL rats; however, this condition was unresponsive to α5PAM treatment or vHPC inactivation. HAL addiction withdrawal 24464874 Withdrawal from prior HAL treatment interferes with the therapeutic actions of this novel treatment in the MAM model of schizophrenia. HAL drug amphetamine 22927669 We have shown previously that rats withdrawn from continuous haloperidol (HAL) treatment (via subcutaneous minipump) develop dopamine supersensitivity and pursue reward cues more vigorously than HAL naive rats following an amphetamine (AMPH) challenge.

HAL addiction reward 22927669 Thus, we compared the effects of HAL and the atypical antipsychotic olanzapine (OLZ) on the pursuit of reward cues. HAL addiction withdrawal 22927669 Withdrawal from HAL, but not from OLZ, enhanced this effect. HAL drug amphetamine 22927669 HAL, but not OLZ, also enhanced AMPH induced psychomotor activation and c fos mRNA expression in the caudate putamen. HAL drug amphetamine 22927669 Thus, prior HAL, but not OLZ, enhanced conditioned reward following an AMPH challenge, and this was potentially linked to enhanced behavioral sensitivity to AMPH and AMPH induced engagement of the caudate putamen.

HAL addiction reward 22927669 These findings suggest that HAL, but not an atypical like OLZ, modifies reward circuitry in ways that increase responsiveness to reward cues. HAL drug amphetamine 20557320 Three experiments were designed to evaluate the roles of DAD2 receptor antagonist haloperidol (HAL) and glutamatergic N methyl d aspartate receptor antagonist MK 801 on both the induction and the expression stage of AMPH sensitization in SIP rats.

HAL addiction sensitization 20557320 The present results showed that HAL and MK 801 affected the effect of AMPH differently during the process of sensitization. HAL addiction sensitization 20557320 Whereas HAL influenced the sensitization during both the induction and the expression phases, MK 801 affected only the induction phase; thus, once the sensitization had been established, MK 801 had no further influence. HAL drug amphetamine 20034231 However pretreatment with DAD2 antagonist haloperidol (HAL) prevented the sensitization to AMPH in the long term rather than short term withdrawal conditions.

HAL drug alcohol 17005368 Haloperidol (HAL) evoked DA release was suppressed in groups exposed prenatally to ethanol, while HAL evoked DOPAC and HVA release was greatest after co exposure to prenatal cadmium and ethanol. HAL drug alcohol 17005368 These in vivo microdialysis results indicate that ontogenetic co exposure to cadmium, and ethanol produces a long lived suppressive effect on HAL evoked DA release and a long lived enhancing effect on AMPH evoked DA release in rat striatum. HAL drug amphetamine 17005368 These in vivo microdialysis results indicate that ontogenetic co exposure to cadmium, and ethanol produces a long lived suppressive effect on HAL evoked DA release and a long lived enhancing effect on AMPH evoked DA release in rat striatum. HAL drug amphetamine 16768607 Either amphetamine (AMPH; 0.5 or 1.0 mg/kg) or haloperidol (HAL; 0.1 mg/kg) were injected before 1 or all of the 3 PE sessions. HAL drug amphetamine 16768607 AMPH blocked the acquisition of LI if it was injected before each or before only the last PE session and HAL potentiated LI. HAL drug amphetamine 15894057 In the present experiment rats were trained on a three lever, drug discrimination task to discriminate the cues associated with 0.30 mg/kg of the indirect dopamine (DA) agonist, amphetamine (AMPH), saline (SAL), and 0.03 mg/kg of the DA, D2 receptor antagonist, haloperidol (HAL). HAL drug amphetamine 15894057 Choice behavior determined from tests on 0.30 and 0.15 mg/kg AMPH, SAL 0.03 and 0.015 mg/kg HAL provided a behavioral baseline presumed to represent changes along a continuum of DA mediated, interoceptive cues. HAL drug amphetamine 15894057 Results from separate groups tested on 0.30 and 0.15 mg/kg AMPH, SAL, 0.03 and 0.015 mg/kg HAL, 24 h post treatment with an acute 7.5 mg/kg dose of AMPH, showed rapid tolerance and withdrawal to the AMPH cue and sensitization to the HAL cue. HAL addiction sensitization 15894057 Results from separate groups tested on 0.30 and 0.15 mg/kg AMPH, SAL, 0.03 and 0.015 mg/kg HAL, 24 h post treatment with an acute 7.5 mg/kg dose of AMPH, showed rapid tolerance and withdrawal to the AMPH cue and sensitization to the HAL cue. HAL addiction withdrawal 15894057 Results from separate groups tested on 0.30 and 0.15 mg/kg AMPH, SAL, 0.03 and 0.015 mg/kg HAL, 24 h post treatment with an acute 7.5 mg/kg dose of AMPH, showed rapid tolerance and withdrawal to the AMPH cue and sensitization to the HAL cue. HAL drug amphetamine 15894057 The same tests 24 h following treatment with 1.0 mg/kg HAL showed rapid tolerance to the HAL cue, sensitization to the AMPH cue, but not AMPH like withdrawal cues. HAL addiction sensitization 15894057 The same tests 24 h following treatment with 1.0 mg/kg HAL showed rapid tolerance to the HAL cue, sensitization to the AMPH cue, but not AMPH like withdrawal cues. HAL addiction withdrawal 15894057 The same tests 24 h following treatment with 1.0 mg/kg HAL showed rapid tolerance to the HAL cue, sensitization to the AMPH cue, but not AMPH like withdrawal cues. HAL drug amphetamine 15894057 Analysis of the results showed that tolerance to the AMPH and HAL cues reflected neuroadaptive baseline shifts and not weaker cue properties. HAL drug amphetamine 15582685 Since dopamine (DA) has been implicated in mediating the AMPH cue, rats were trained to discriminate between 0.25 mg/kg AMPH, an indirect DA agonist, and 0.033 mg/kg haloperidol (HAL), a DA antagonist at the D2 receptor site. HAL drug amphetamine 15582685 Following acquisition of the discrimination, rats were tested for choice of responding on the AMPH and HAL levers at intervals from 6 to 72 h following treatment with a single dose of 3.0 mg/AMPH. HAL drug amphetamine 15582685 At short intervals after treatment with 3.0 mg/kg AMPH, rats responded primarily on the AMPH lever followed by a shift to predominant responding on the HAL lever 16 30 h post treatment, before returning to predrug levels. HAL drug amphetamine 12898122 It is well established that LI is impaired in rats and in humans by injections of the indirect dopamine agonist amphetamine (AMPH), and that this disruption can be prevented by co administration of either the typical neuroleptic haloperidol (HAL) or the atypical neuroleptic clozapine (CLZ). HAL drug amphetamine 12898122 We tested whether AMPH (0.5 mg/kg) pretreatment would disrupt LI of a conditioned aversion to sucrose, and if so, which stage of the procedure is critical for mediating the disruption; in addition, we tested whether HAL (0.2 mg/kg) or CLZ (5.0 mg/kg) could restore such an expected LI disruption. HAL addiction aversion 12898122 We tested whether AMPH (0.5 mg/kg) pretreatment would disrupt LI of a conditioned aversion to sucrose, and if so, which stage of the procedure is critical for mediating the disruption; in addition, we tested whether HAL (0.2 mg/kg) or CLZ (5.0 mg/kg) could restore such an expected LI disruption. HAL drug amphetamine 12898122 When HAL or CLZ was given 40 min before AMPH (before both pre exposure and conditioning), it blocked LI disruption. HAL drug amphetamine 9972698 Both of those stress induced immunosuppressive responses were no longer evident when AMPH pretreated rats were injected with haloperidol (HAL, 1 mg/kg i.p.) HAL drug amphetamine 8808141 Apomorphine (APO), amphetamine (AMP), and haloperidol (HAL) were administered systemically. HAL addiction reward 8201803 Our paper compares the effect of homopantothenic acid (HOPA) and haloperidol (HAL), i.e., representative neuroleptics, on intracranial self stimulation (ICSS) and locomotor activity. HAL addiction reward 8201803 On the other hand, haloperidol (HAL) markedly inhibited both ICSS and abnormal hyperactivity induced by MAP. HAL addiction withdrawal 8216693 The release and metabolism of dopamine (DA) in the striatum of these animals was then assessed using intracranial microdialysis during week 32 of HAL administration and 3 days after withdrawal of HAL. HAL addiction withdrawal 8216693 Three days after withdrawal from HAL, no difference was seen in basal extracellular concentrations of any of the analytes. HAL drug amphetamine 8216693 No difference in the magnitude of DA release was seen between groups following local application of amphetamine (10 microM) through the dialysis probe during or after chronic HAL administration. HAL addiction withdrawal 8216693 These results confirm previous findings that long term HAL administration produces increased DA turnover during HAL administration, but that this increase does not persist following HAL withdrawal. HAL addiction sensitization 1615128 The results indicated that injections of HAL given at IDIs of 1 or 2 days produced neither tolerance nor sensitization, whereas injections given at intervals of 7 or 14 days produced sensitization. HAL addiction sensitization 1615128 Sensitization was also observed in the control groups, perhaps as a result of the intermittent schedule of HAL injections given during the dose response tests. HAL drug amphetamine 1615128 Sensitization to HAL was not accompanied by changes in sensitivity to amphetamine. HAL addiction sensitization 1615128 Sensitization to HAL was not accompanied by changes in sensitivity to amphetamine. HAL addiction sensitization 1615128 In addition, evidence is presented that sensitization to HAL induced hypophagia is contingent on behavioral experience under the drug.

HAL drug amphetamine 1365673 Rats were trained to discriminate between 0.25 mg/kg amphetamine (AMPH) and 0.03 mg/kg haloperidol (HAL) in a two lever drug discrimination task. HAL drug amphetamine 1365673 In order to test for a drug induced withdrawal state, animals were assigned to one of three chronic treatment groups and given injections of AMPH, HAL, or distilled water (DW) for 10 consecutive days. HAL addiction withdrawal 1365673 In order to test for a drug induced withdrawal state, animals were assigned to one of three chronic treatment groups and given injections of AMPH, HAL, or distilled water (DW) for 10 consecutive days. HAL drug amphetamine 1365673 At the 24 h retest interval, subjects injected with AMPH responded as though administered an acute dose of HAL (0.028 mg/kg) and subjects injected with chronic HAL responded as though administered an acute dose of AMPH (0.15 mg/kg). HAL drug amphetamine 1365673 To determine whether the rebound observed after 10 days of drug treatment was present after a single injection, independent groups of subjects were injected with single doses of either 10 mg/kg AMPH or 1.0 mg/kg HAL and then retested from 4 h to 48 h later. HAL drug amphetamine 1365673 Single doses of both AMPH and HAL produced significant rebounds that peaked between 20 h (AMPH) and 24 h (HAL) following administration. HAL drug amphetamine 1365673 In a third experiment, animals were tested with or without acute doses of drug following pretreatment with either HAL or AMPH. HAL drug amphetamine 1365673 Receptor supersensitivity accounts for the tolerance observed to HAL 24 h after treatment with 1.0 mg/kg HAL, whereas receptor subsensitivity accounts for the tolerance observed 20 h after treatment with 10 mg/kg AMPH. HAL drug amphetamine 1646666 Haloperidol (HAL) treatment failed to block the stimulant induced increase in kindling acquisition indicating that changes in dopamine (DA) are not necessary for the AMPH/kindling synergism to develop.

HAL addiction withdrawal 4080767 This study was designed to assess whether phencyclidine (PCP) produces dopamine (DA) dependent behaviors such as licking, biting and gnawing at low doses after withdrawal from chronic haloperidol (HAL) treatment in rats. HAL addiction withdrawal 4080767 Low doses of PCP (2.5 and 5 mg/kg) produced licking, gnawing, biting and self biting in rats after withdrawal from chronic HAL treatment, which were not observed in the vehicle pretreated rats given PCP at the same dose range. HAL drug amphetamine 4080767 These behaviors were similar to DA dependent behaviors produced by methamphetamine and apomorphine in rats after withdrawal from chronic HAL treatment. HAL addiction withdrawal 4080767 These behaviors were similar to DA dependent behaviors produced by methamphetamine and apomorphine in rats after withdrawal from chronic HAL treatment. HAL addiction withdrawal 4080767 Furthermore, at doses of 5 or 7.5 mg/kg, PCP induced head weaving and backpedalling, which were mediated by both DA and serotonin (5 HT) neurons, significantly increased in rats after withdrawal from chronic HAL treatment. HAL drug benzodiazepine 6151209 Acute drug effects on the three dependent variables were assessed for dose ranges of haloperidol (HAL), chlorpromazine (CPZ), clozapine (CLZ), and chlordiazepoxide (CDP).

TSPO addiction reward 32698131 These findings provide further reinforcement that the much sought after mechanism of TSPO/PBR function remains correlated with the extent of cellular triglyceride metabolism. TSPO drug amphetamine 32570138 No significant elevation of translocator protein binding in the brains of recently abstinent methamphetamine users. TSPO drug amphetamine 32570138 One study using this approach showed substantial TSPO elevation throughout the brain in chronic methamphetamine users following long term abstinence (0.5 4 years), but clients typically present for treatment earlier in abstinence. TSPO drug amphetamine 32570138 We used PET with [11C]DAA1106 to compare standardized uptake values (SUVs) as an index of TSPO binding in the brains of methamphetamine dependent participants who were abstinent for < 6 months (n = 11) and healthy controls (n = 12). TSPO drug amphetamine 32570138 The discrepancy between the lack of significant difference in TSPO binding in early abstinent methamphetamine users vs. controls in this study and a previous report of elevated binding in longer abstinent methamphetamine users may reflect methodological differences or limitations of TSPO binding as an index of neuroinflammation.

IL18 addiction intoxication 17220368 Acute alcohol intoxication increases interleukin 18 mediated neutrophil infiltration and lung inflammation following burn injury in rats. IL18 drug alcohol 17220368 In this study, we examined whether IL 18 plays a role in lung inflammation following alcohol (EtOH) and burn injury. IL18 addiction intoxication 17220368 On day 1 after injury, lung tissue IL 18, neutrophil chemokines (CINC 1/CINC 3), ICAM 1, neutrophil infiltration, MPO activity, and water content (i.e., edema) were significantly increased in rats receiving a combined insult of EtOH and burn injury compared with rats receiving either EtOH intoxication or burn injury alone. IL18 addiction intoxication 17220368 These findings suggest that acute EtOH intoxication before burn injury upregulates IL 18, which in turn contributes to increased neutrophil infiltration.

IL18 addiction intoxication 16707557 A novel role for IL 18 in corticosterone mediated intestinal damage in a two hit rodent model of alcohol intoxication and injury. IL18 addiction intoxication 16707557 To further delineate the mechanism of impaired intestinal barrier function, the present study examined the role of corticosterone (CORT) and interleukin (IL) 18, as CORT and IL 18 are elevated following a combined insult of EtOH intoxication and burn injury. IL18 addiction intoxication 16707557 These findings suggest that a combined insult of EtOH and burn injury results in increased CORT levels, which in turn up regulates intestinal IL 18 levels and thereby causes altered intestinal barrier function following a combined insult of EtOH intoxication and burn injury. AGRP drug alcohol 32045262 Acute alcohol exposure also increases both the activity of agouti related protein (AgRP) expressing neurons and AgRP immunoreactivity. AGRP drug alcohol 32045262 Here, we show that adenosine receptor A2B signaling in the brain modulates the extent of alcohol induced fatty liver in mice and that both the AgRP neuropeptide and the sympathetic nervous system are indispensable for hepatic steatosis induced by bingelike alcohol consumption. AGRP drug alcohol 32045262 Together, these results indicate that the brain plays an integral role in alcohol induced hepatic lipid accumulation and that central adenosine signaling, hypothalamic AgRP, and the sympathetic nervous system are crucial mediators of this process. AGRP drug amphetamine 30929417 Lorcaserin stimulates proopiomelanocortin (POMC)/cocaine and amphetamine regulated transcript (CART) neurons and inhibits neuropeptide Y (NPY)/agouti related peptide (AgRP) neurons, which results in the activation of melanocortin 3/4 receptors.

AGRP drug alcohol 25975524 Male C57BL/6J mice were exposed to one, three or six cycles of binge like ethanol, sucrose or water drinking, after which brain tissue was processed via immunohistochemistry (IHC) for analysis of key MC peptides, including alpha melanocyte stimulating hormone (α MSH) and agouti related protein (AgRP). AGRP addiction intoxication 25975524 Male C57BL/6J mice were exposed to one, three or six cycles of binge like ethanol, sucrose or water drinking, after which brain tissue was processed via immunohistochemistry (IHC) for analysis of key MC peptides, including alpha melanocyte stimulating hormone (α MSH) and agouti related protein (AgRP).

AGRP drug alcohol 24917782 This review highlights recent genetic and pharmacological findings that have implicated roles for the MC and AgRP systems in modulating ethanol consumption. AGRP drug alcohol 24917782 Ethanol consumption is associated with significant alterations in the expression levels of various MC peptides/protein, which suggests that ethanol induced perturbations of MC/AgRP signaling may modulate excessive ethanol intake. AGRP drug alcohol 24917782 Consistently, MCR agonists decrease, and AgRP increases, ethanol consumption in mice. AGRP drug alcohol 24917782 Finally, mutant mice lacking AgRP exhibit blunted voluntary and binge like ethanol drinking, consistent with pharmacological studies.

AGRP drug cocaine 23872279 or intra nucleus accumbens injection with AgRP(83 132) or saline, to determine whether we could inhibit cocaine induced locomotor sensitisation. AGRP drug cocaine 23872279 injections of AgRP(83 132) inhibit cocaine induced locomotor sensitisation. AGRP drug cocaine 23872279 This effect is not regulated via the nucleus accumbens, since injecting the melanocortin receptor inverse agonist AgRP(83 132) directly into the nucleus accumbens was unable to inhibit the cocaine induced locomotor sensitisation. AGRP drug alcohol 23792540 Given the involvement of MC and the endogenous inverse agonist AgRP in ethanol drinking, here we evaluate whether a binge like pattern of ethanol treatment during adolescence has a relevant impact on basal and/or ethanol stimulated α MSH and AgRP activities during adulthood. AGRP addiction intoxication 23792540 Given the involvement of MC and the endogenous inverse agonist AgRP in ethanol drinking, here we evaluate whether a binge like pattern of ethanol treatment during adolescence has a relevant impact on basal and/or ethanol stimulated α MSH and AgRP activities during adulthood. AGRP drug alcohol 23792540 Following 25 ethanol free days, we evaluated α MSH and AgRP immunoreactivity (IR) in the limbic and hypothalamic nuclei of adult rats (PND63) in response to ethanol (1.5 or 3.0 g/kgi.p.) AGRP drug alcohol 23792540 Additionally, acute ethanol elicited AgRP IR in the Arc. AGRP drug alcohol 23792540 Rats given the adolescent ethanol treatment required higher doses of ethanol than saline treated rats to express AgRP. AGRP drug alcohol 23792540 In light of previous evidence that endogenous MC and AgRP regulate ethanol intake through MC receptor signaling, we speculate that the α MSH and AgRP disturbances induced by binge like ethanol exposure during adolescence may contribute to excessive ethanol consumption during adulthood.

AGRP drug cocaine 22729177 We found that impairment of Agouti related protein (AgRP) circuitry by either Sirt1 knockdown in AgRP expressing neurons or early postnatal ablation of these neurons increased exploratory behavior and enhanced responses to cocaine. AGRP addiction reward 22729177 Thus, AgRP neurons determine the set point of the reward circuitry and associated behaviors. AGRP drug alcohol 22245775 Finally, recent evidence shows that corticotropin releasing factor (CRF), agouti related protein (AgRP), neuropeptide Y (NPY), and ghrelin are also implicated as impacting this pattern of ethanol consumption.

AGRP addiction intoxication 20102560 Consistently, genetic deletion of the endogenous MCR antagonist, agouti related protein (AgRP), causes reductions of ethanol reinforced lever pressing and binge like ethanol drinking in C57BL/6J mice. AGRP drug alcohol 20102560 To further characterize the role of the MC system in responses to ethanol, here we compared AgRP and alpha MSH immunoreactivity in response to an acute injection of saline or ethanol between high ethanol drinking C57BL/6J mice and moderate ethanol drinking 129/SvJ mice. AGRP drug alcohol 20102560 Results indicated that acute ethanol administration triggered a dose dependent increase in AgRP immunoreactivity in the arcuate (ARC) of C57BL/6J mice, an effect that was not evident in the 129/SvJ strain. AGRP drug alcohol 20102560 The results show that acute ethanol exposure has direct effects on endogenous AgRP activity in ethanol preferring C57BL/6J mice. AGRP drug alcohol 20102560 It is suggested that ethanol induced increases in AgRP may be part of a positive feedback system that stimulates excessive binge like ethanol drinking in C57BL/6J mice. AGRP addiction intoxication 20102560 It is suggested that ethanol induced increases in AgRP may be part of a positive feedback system that stimulates excessive binge like ethanol drinking in C57BL/6J mice. AGRP drug alcohol 19566712 Because central administration of the functionally active AgRP fragment AgRP (83 132) increases ethanol intake by C57BL/6 J mice, we determined if mutant mice lacking normal production of AgRP (AgRP( / )) and maintained on a C57BL/6 J genetic background would show reduced self administration of ethanol relative to littermate wild type (AgRP(+/+)) mice. AGRP drug alcohol 19566712 AgRP( / ) mice showed reduced 8% (v/v) ethanol reinforced lever pressing behavior relative to AgRP(+/+) mice in daily 2 h sessions, but normal sucrose , saccharin and water reinforced lever pressing. AGRP drug alcohol 19566712 Similarly, AgRP( / ) mice showed reduced consumption of 8% ethanol in a two bottle limited access test (2 h/day), although this effect was largely sex dependent. AGRP drug alcohol 19566712 Using drinking in the dark (DID) procedures, AgRP( / ) mice showed blunted binge like drinking of 20% (v/v) ethanol which was associated with lower blood ethanol levels (85 mg/dl) relative to AgRP(+/+) mice (133 mg/dl) after 4 h of intake.

AGRP drug alcohol 19566712 AgRP( / ) mice showed normal ethanol metabolism and did not show altered sensitivity to the sedative effects of ethanol. AGRP drug alcohol 19566712 These observations with genetically altered mice are consistent with previous pharmacological data and suggest that endogenous AgRP signaling modulates the reinforcing properties of ethanol and binge like ethanol drinking. AGRP addiction intoxication 19566712 These observations with genetically altered mice are consistent with previous pharmacological data and suggest that endogenous AgRP signaling modulates the reinforcing properties of ethanol and binge like ethanol drinking. AGRP addiction reward 19566712 These observations with genetically altered mice are consistent with previous pharmacological data and suggest that endogenous AgRP signaling modulates the reinforcing properties of ethanol and binge like ethanol drinking. AGRP drug alcohol 18162070 We also determined if ethanol exposure would alter the immunoreactivity of agouti related protein (AgRP), an endogenous MCR antagonist. AGRP drug alcohol 18162070 No significant ethanol induced alterations in hypothalamic AgRP immunoreactivity were detected. AGRP drug alcohol 16198024 To better understand the role of the MC system in the control of ethanol intake, we tested the acute and chronic effects of lateral ventricular (LV) injections of 0.01 1 nmol MTII, of 0.1 1 nmol of the MC3/4R receptor antagonist agouti related peptide (AgRP), and 0.1 0.5 nmol of the MC3/4R receptor antagonist SHU9119 on food, water, and 10% ethanol intake in Marchigian Sardinian alcohol preferring (msP) rats, which spontaneously ingest pharmacologically relevant quantities of ethanol both under short and long term access conditions. AGRP drug alcohol 16198024 Finally, acute LV injection of neither AgRP nor SHU9119 affected ethanol intake under ad libitum conditions, although both antagonists significantly increased food and water intake. AGRP drug opioid 12851315 Given these observations, we wished to examine whether the effects of AgRP on ingestive behavior resemble those of opioids. AGRP drug opioid 12851315 As a result of AgRP injection, animals increased intake of chow but not sucrose relative to controls, in contrast to what has been seen with opioid agonists. AGRP drug opioid 12851315 These results together with prior findings suggest that the primary effect of AgRP is to cause an increase in food intake to satisfy energy needs, though AgRP also has opioid like effects, possibly due to melanocortin opioid interactions. AGRP drug opioid 12151802 Initial studies suggest similarities between the effects of Agrp and opioid peptides on ingestive behavior. AGRP drug opioid 12151802 Given these observations, we examined whether Agrp, similarly to opioids, alleviates conditioned taste aversion (CTA) generated by peripheral injection of LiCl.

TACR1 drug alcohol 20112009 The objective of this study is to obtain an expanded preclinical validation of NK1R antagonism as a candidate therapeutic mechanism in alcohol use disorders. TACR1 drug alcohol 20112009 The NK1R antagonist L 703,606 and NK1R KO mice were used in models that assess alcohol related behaviors. TACR1 drug alcohol 20112009 dose dependently suppressed alcohol intake in WT C57BL/6 mice under two bottle free choice conditions but was ineffective in NK1R KO:s, demonstrating the receptor specificity of the effect. TACR1 drug alcohol 20112009 Alcohol reward, measured as conditioned place preference for alcohol, was reduced by NK1R receptor deletion in a gene dose dependent manner. TACR1 addiction reward 20112009 Alcohol reward, measured as conditioned place preference for alcohol, was reduced by NK1R receptor deletion in a gene dose dependent manner. TACR1 drug alcohol 20112009 Acute blockade of NK1R:s mimics the effects of NKR1 gene deletion on alcohol consumption, supporting a direct rather than developmental role of the receptor in regulation of alcohol intake. TACR1 drug alcohol 20112009 Inactivation of NK1R:s critically modulates alcohol reward and escalation, two key characteristics of addiction.

TACR1 addiction reward 20112009 Inactivation of NK1R:s critically modulates alcohol reward and escalation, two key characteristics of addiction. TACR1 drug alcohol 20112009 These data provide critical support for NK1R antagonism as a candidate mechanism for treatment of alcoholism. TACR1 drug amphetamine 19748515 In the course of this work, we discovered that NK1R / mice express locomotor hyperactivity that is prevented by psychostimulants (d amphetamine or methylphenidate). TACR1 drug amphetamine 19748515 Moreover, hyperactivity is induced in wildtypes by treating them with an NK1R antagonist (at doses that have no effect on the behaviour of NK1R / mice): this hyperactivity is prevented by d amphetamine, as in NK1R / mice. TACR1 drug alcohol 19553914 Genetic and pharmacological studies show that binding of ligands to NK1R decreases anxiety related behaviors, and therefore, self administration of alcohol in mice and craving for alcohol in humans. TACR1 addiction relapse 19553914 Genetic and pharmacological studies show that binding of ligands to NK1R decreases anxiety related behaviors, and therefore, self administration of alcohol in mice and craving for alcohol in humans. TACR1 drug alcohol 19553914 As genetic variants may result in differential expression of the receptor through various molecular mechanisms, we examined whether allelic variations in the NK1R gene are associated with alcohol dependence (AD) by genotyping 11 single nucleotide polymorphisms (SNPs) across NK1R in alcoholic (n=271) and healthy control (n=337) participants of Caucasian descent.

TACR1 addiction reward 19129399 NK1R activation affects opioid reward specifically, however, and the cellular basis for this specificity is unknown. TACR1 drug opioid 19129399 NK1R mediated regulation of MOR trafficking was associated with reduced opioid induced desensitization of adenylyl cyclase signaling in striatal neurons. TACR1 drug opioid 19129399 These results identify a cell autonomous mechanism that may underlie the highly specific effects of NK1R on opioid signaling and suggest, more generally, that receptor specific trafficking of arrestins may represent a fundamental mechanism for coordinating distinct GPCR mediated signals at the level of individual CNS neurons. TACR1 drug alcohol 19081000 In a preclinical and experimental clinical study George and colleagues first investigated the role of Substance P and its receptor (NK1R) in the context of alcoholism. TACR1 drug alcohol 18276852 We investigated the role of the neurokinin 1 receptor (NK1R), a mediator of behavioral stress responses, in alcohol dependence and treatment. TACR1 addiction dependence 18276852 We investigated the role of the neurokinin 1 receptor (NK1R), a mediator of behavioral stress responses, in alcohol dependence and treatment. TACR1 drug alcohol 18276852 In preclinical studies, mice genetically deficient in NK1R showed a marked decrease in voluntary alcohol consumption and had an increased sensitivity to the sedative effects of alcohol. TACR1 drug alcohol 18276852 In a randomized controlled experimental study, we treated recently detoxified alcoholic inpatients with an NK1R antagonist (LY686017; n = 25) or placebo (n = 25). TACR1 drug alcohol 18276852 Thus, as assessed by these surrogate markers of efficacy, NK1R antagonism warrants further investigation as a treatment in alcoholism. TACR1 drug opioid 15908510 Intrathecal morphine infusion (40 nmol/microl/h) for 1 day possessed similar analgesic efficacy as acute morphine and blocked compression induced spinal NK1r internalization. TACR1 drug opioid 15908510 After 5 days of morphine infusion, thermal escape latencies were the same as in preinfusion animals or saline infused controls, and compression evoked NK1r internalization was no longer suppressed. TACR1 drug opioid 15908510 Systemic administration of naloxone to rats on day 6 of morphine infusion resulted in prominent withdrawal behaviors and a concomitant increase in NK1r internalization in dorsal horn. TACR1 addiction withdrawal 15908510 Systemic administration of naloxone to rats on day 6 of morphine infusion resulted in prominent withdrawal behaviors and a concomitant increase in NK1r internalization in dorsal horn. TACR1 drug opioid 15908510 The naloxone induced internalization was blocked by NK1r antagonist L 703,606 [cis 2 (diphenylmethyl) N [(2 iodophenyl)methyl] 1 azabicyclo[2.2.2]octan 3 amine] or pretreatment with capsaicin, confirming that the internalization is due to the endogenous SP release from the primary afferents. PARP1 drug cocaine 32641757 Interestingly, acute or chronic cocaine exposure downregulated miR 124 levels concomitant with upregulation of PARP 1 protein in dopaminergic like neuronal cells in culture. PARP1 drug cocaine 32641757 Collectively, these studies identify Parp 1 as a direct target of miR 124 in neuronal cells, establish miR 124 as a cocaine regulated miRNA in the mouse NAc, and highlight a novel pathway underlying the molecular effects of cocaine. PARP1 drug amphetamine 32086884 In addition, to explore METH induced neurotoxicity, we measured the level of Parkin and the phosphorylation levels of α syn, Polo like kinase 2 (PLK2), the proteasome activity marker CD3δ, and the apoptosis related proteins Caspase 3 and PARP. PARP1 drug alcohol 31251945 PARP inhibition in vivo blocks alcohol induced brain neurodegeneration and neuroinflammatory cytosolic phospholipase A2 elevations. PARP1 drug alcohol 31251945 Concurrent with neurodegeneration, alcohol elevates poly (ADP ribose) polymerase 1 (PARP 1) and cytosolic phospholipase A2 (cPLA2) levels. PARP1 drug alcohol 31251945 Inhibitors of PARP exert in vitro neuroprotection while suppressing cPLA2 elevations in alcohol treated HC ECX slice cultures. PARP1 drug alcohol 31251945 Here, we examined in vivo neuroprotection and cPLA2 suppression by the PARP inhibitor, veliparib, in a recognized adult rat model of alcohol binging. PARP1 drug alcohol 31251945 These in vivo results support an emerging key role for PARP in binge alcohol induced neurodegeneration and cPLA2 related neuroinflammation.

PARP1 drug alcohol 29339456 Using rat adult age hippocampal entorhinal cortical (HEC) slice cultures, we examined the role of poly [ADP ribose] polymerase (PARP) in binge ethanol's brain inflammatory and neurodegenerative mechanisms. PARP1 addiction intoxication 29339456 Using rat adult age hippocampal entorhinal cortical (HEC) slice cultures, we examined the role of poly [ADP ribose] polymerase (PARP) in binge ethanol's brain inflammatory and neurodegenerative mechanisms. PARP1 drug alcohol 29339456 Previously, we found that brain PARP1 levels were upregulated by neurotoxic ethanol binges in adult rats and HEC slices, and PARP inhibitor PJ34 abrogated slice neurodegeneration. PARP1 drug alcohol 29339456 Previously, we found that brain PARP1 levels were upregulated by neurotoxic ethanol binges in adult rats and HEC slices, and PARP inhibitor PJ34 abrogated slice neurodegeneration. PARP1 drug alcohol 29339456 We now find in 4 day binged HEC slice cultures (100 mM ethanol) that PARP1 elevations after two overnight binges precede PAR, cPLA2, and sPLA2 enhancements by 1 day and high mobility group box 1 (HMGB1), an ethanol responsive alarmin that augments proinflammatory cytokines via toll like receptor 4 (TLR4), by 2 days. PARP1 drug alcohol 29339456 After verifying that PJ34 effectively blocks PARP activity (↑PAR), we demonstrated that, like PJ34, three other PARP inhibitors olaparib, veliparib, and 4 aminobenzamide provided neuroprotection from ethanol. PARP1 drug alcohol 29339456 Importantly, PJ34 and olaparib also prevented ethanol's amplification of the PLA2 isoenzymes, and two PLA2 inhibitors were neuroprotective thus coupling PARP to PLA2, with PLA2 activity promoting neurodegeneration. PARP1 drug alcohol 29339456 Also, PJ34 and olaparib blocked ethanol induced HMGB1 elevations, linking brain PARP induction to TLR4 activation. PARP1 drug alcohol 29339456 The results provide evidence in adult brains that induction of PARP1 may mediate dual neuroinflammatory pathways (PLA2→phospholipid→ARA and HMGB1→TLR4→proinflammatory cytokines) that are complicit in binge ethanol induced neurodegeneration.

PARP1 drug alcohol 27527870 Ethanol caused both apoptotic and necrotic cell death which was demonstrated by the increase in active caspase 3, caspase 8, cleaved PARP, cleaved CK 18 and the secretion of high mobility group protein B1 (HMGB1). PARP1 drug psychedelics 26068050 In fact, chronic MDMA inhibited proteins of the apoptotic pathway (i.e., pro apoptotic FADD, Bax and cytochrome c) leading to an inhibition of cell death markers (i.e., p JNK1/2, cleavage of PARP 1) and suggesting regulatory mechanisms in response to the neurochemical changes caused by the drug. PARP1 drug amphetamine 25631491 In addition, blocking caspase 11 expression inhibited METH induced activation of caspase 3 and PARP in vitro and in vivo, suggesting that caspase 11/caspase 3 signal pathway is involved in METH induced neurotoxicity. PARP1 drug alcohol 25029343 We report here that neurotoxic binge ethanol exposure produces comparable significant effects in vivo and in vitro on adult rat brain levels of AQP4 as well as neuroinflammation linked enzymes: key phospholipase A2 (PLA2) family members and poly (ADP ribose) polymerase 1 (PARP 1).

PARP1 drug cocaine 24449909 Here, we identify an essential role for PARP 1 in cocaine induced molecular, neural, and behavioral plasticity.

PARP1 addiction reward 24449909 Repeated cocaine administration, including self administration, increased global levels of PARP 1 and its mark PAR in mouse nucleus accumbens (NAc), a key brain reward region. PARP1 drug cocaine 24449909 Using PARP 1 inhibitors and viral mediated gene transfer, we established that PARP 1 induction in NAc mediates enhanced behavioral responses to cocaine, including increased self administration of the drug. PARP1 drug cocaine 24449909 Using chromatin immunoprecipitation sequencing, we demonstrated a global, genome wide enrichment of PARP 1 in NAc of cocaine exposed mice and identified several PARP 1 target genes that could contribute to the lasting effects of cocaine. PARP1 drug cocaine 24449909 Specifically, we identified sidekick 1 important for synaptic connections during development as a critical PARP 1 target gene involved in cocaine's behavioral effects as well as in its ability to induce dendritic spines on NAc neurons. PARP1 drug cocaine 24449909 These findings establish the involvement of PARP 1 and PARylation in the long term actions of cocaine. PARP1 drug opioid 24281942 In the HPC, morphine significantly increased the ratio of Bax/Bcl 2, caspases 3, and PARP by the lowest dose (0.5 mg/kg), but, in the VTA, a considerable increase was seen in the dose of 5 mg/kg; promotion of apoptotic factors in the HPC and VTA insinuates that morphine can affect the molecular mechanisms that interfere with apoptosis through different receptors. PARP1 drug opioid 24096212 In the NAc, morphine significantly increased the Bax/Bcl 2 ratio, caspase3 and PARP in the lowest dose (0.5mg/kg) but in the PFC considerable increase was seen in dose of 5mg/kg.

PARP1 drug cocaine 21925237 This postmortem human brain study examined the status of canonical apoptotic pathways, signaling partners, and the cleavage of poly(ADP ribose) polymerase 1 (PARP 1), a sensor of DNA damage, in prefrontal cortex (PFC) of a small but well characterized cohort of cocaine abusers (n=10). PARP1 drug cocaine 21925237 In the same brain samples of cocaine abusers, the proteolytic cleavage of PARP 1 was increased (+39%). PARP1 drug cocaine 21925237 Chronic exposure to cocaine in rats, including withdrawal for 3 days, did not alter Fas FADD receptor complex, cytochrome c, caspase 3/fragments, AIF, PARP 1 cleavage, and associated signaling in the cerebral cortex.

PARP1 drug amphetamine 15113847 The oxidative stress induced by METH putatively activates nuclear enzyme poly(ADP ribose) polymerase (PARP), with excessive PARP activation eventually leading to cell death. PARP1 drug amphetamine 15113847 In this study, we show that prevention of PARP activation by treatment with FR261529 [2 (4 chlorophenyl) 5 quinoxalinecarboxamide], the compound that was recently identified as a novel PARP inhibitor (IC50 for PARP 1 = 33 nM, IC50 for PARP 2 = 7 nM), protects against both ROS induced cells injury in vitro and METH induced dopaminergic neuronal damage in an in vivo Parkinson's disease (PD) model. PARP1 drug amphetamine 15113847 In PC12 cells, exposure of hydrogen peroxide or METH markedly induced PARP activation, and treatment with FR261529 (1 microM) significantly reduced PARP activation and attenuated cell death. PARP1 drug amphetamine 15113847 These findings indicate that the neuroprotective effects of a novel PARP inhibitor, FR261529, were accompanied by inhibition of METH induced PARP activation, suggesting that METH induces nigrostriatal dopaminergic neurodegeneration involving PARP activation and also orally active and brain penetrable PARP inhibitor FR261529 could be a novel attractive therapeutic candidate for neurodegenerative disorders such as PD.

MYH14 drug psychedelics 32685891 Myosin activated coagulation seems a potential cause of MDMA related coagulopathy in the setting of rhabdomyolysis and serotonin syndrome. MYH14 drug amphetamine 32066582 Methamphetamine learning induces persistent and selective nonmuscle myosin II dependent spine motility in the basolateral amygdala. MYH14 drug amphetamine 32066582 Nonmuscle myosin II inhibition (NMIIi) in the basolateral amygdala (BLA), but not dorsal hippocampus (CA1), selectively disrupts memories associated with methamphetamine (METH) days after learning, without retrieval. MYH14 drug amphetamine 32066582 We employed time lapse two photon imaging of dendritic spine motility in acutely prepared brain slices from female and male mice following METH associated learning as a readout of actin myosin dynamics. MYH14 drug cocaine 31596232 The release of EVs occurs when cocaine causes dissociation of the Sig 1R from ADP ribosylation factor (ARF6), a G protein regulating EV trafficking, leading to activation of myosin light chain kinase (MLCK). MYH14 drug alcohol 31411733 While alcohol did not alter the content of high energy phosphates or oxidative phosphorylation complexes I V, it did reduce myosin heavy chain and troponin T content. MYH14 drug amphetamine 30115760 Using pharmacologic and genetic approaches targeting actin or the actin driving molecular motor, nonmuscle myosin II (NMII), we previously discovered an immediate, retrieval independent, and long lasting disruption of methamphetamine (METH ) and amphetamine associated memories. MYH14 drug psychedelics 28890736 Treatment of the larvae with 25B NBOMe decreased their survival rate, locomotion, altered birefringence of the skeletal muscle and immunostainings for dystroglycan (a myoseptal protein) and myosin heavy chain (a myofibril protein), which were consistent with rhabdomyolysis. MYH14 drug amphetamine 28082169 Nonmuscle myosin II inhibition disrupts methamphetamine associated memory in females and adolescents. MYH14 drug alcohol 26859989 It has been shown that chronic alcoholic myopathy develops after 10 years of alcohol abuse; proximal paresis is observed only in patients with atrophy of muscle fibers, thus there is a transformation of myosin phenotype from slow to fast. MYH14 drug amphetamine 26239291 Nonmuscle myosin IIB as a therapeutic target for the prevention of relapse to methamphetamine use. MYH14 addiction relapse 26239291 Nonmuscle myosin IIB as a therapeutic target for the prevention of relapse to methamphetamine use. MYH14 addiction relapse 26239291 A single intra BLC treatment with Blebbistatin (Blebb), a small molecule inhibitor of class II myosin isoforms, including NMIIB, produced a long lasting disruption of context induced drug seeking (at least 30 days). MYH14 addiction relapse 26022262 Similar to an actin depolymerizing compound, pre test inhibition of myosin II ATPase activity in the AMY produced a rapid and lasting disruption of drug seeking behavior. MYH14 addiction relapse 26022262 While many questions remain, these findings indicate that myosin II represents a potential therapeutic avenue to target the actin cytoskeleton and disrupt the powerful, extinction resistant memories capable of triggering relapse. MYH14 drug alcohol 25257290 Pharmacologic agents were used to test the roles of alcohol metabolism, oxidative stress, p38 mitogen activated protein kinase (MAPK), myosin light chain kinase (MLCK), rho kinase (ROCK), and exchange protein activated by cAMP (Epac).

MYH14 drug amphetamine 24012327 Inhibition of non muscle myosin II also resulted in a disruption of METH associated memory. MYH14 drug alcohol 23376955 As this combined insult causes elevated intestinal morphological damage, tight junction protein localization alterations, and phosphorylated myosin light chain levels, we sought to determine the role of IL 6 in these intestinal responses using a model of binge ethanol exposure and burn injury.

MYH14 addiction intoxication 22790598 Inhibition of long myosin light chain kinase activation alleviates intestinal damage after binge ethanol exposure and burn injury. MYH14 drug alcohol 22790598 Knowing that long myosin light chain kinase (MLCK) is important for epithelial barrier maintenance and can be activated by proinflammatory cytokines, we examined whether inhibition of MLCK alleviated detrimental intestinal responses seen after ethanol exposure and burn injury. MYH14 drug amphetamine 20139112 Treatment with methamphetamine also resulted in the tyrosine nitration of myofilament (desmin, myosin light chain) and mitochondrial (ATP synthase, NADH dehydrogenase, cytochrome c oxidase, prohibitin) proteins. MYH14 addiction dependence 19805075 The dependence of TMV, PVX, and TBSV on intact microfilaments for intercellular movement led us to investigate the role of myosin motors in this process. MYH14 addiction sensitization 16472257 Sustained smooth muscle contraction or its experimental counterpart, Ca2+ sensitization, by G(q/13) coupled receptor agonists is mediated via RhoA dependent inhibition of MLC (myosin light chain) phosphatase and MLC20 (20 kDa regulatory light chain of myosin II) phosphorylation by a Ca2+ independent MLCK (MLC kinase). MYH14 drug alcohol 15976526 Ethanol induced activation of myosin light chain kinase leads to dysfunction of tight junctions and blood brain barrier compromise. MYH14 drug alcohol 15690316 The cellular content of actin and alpha myosin heavy chain isoform was significantly reduced and there was an increase in the beta myosin heavy chain isoform after feeding rats a diet containing alcohol. MYH14 drug alcohol 15690316 These results suggest that (1) the reduced protein content observed in the heart after feeding a diet containing alcohol is a consequence of reduced synthesis of both myofibrillar and sarcoplasmic proteins, and (2) the expression of both actin and alpha myosin heavy chain isoform is affected independently of the messenger RNA content of the proteins. MYH14 drug alcohol 11226116 Although ethanol did not affect regulatory myosin light chain (rMLC) phosphorylation during stimulation with Ca(2+) alone, it decreased rMLC phosphorylation by Ca(2+) during muscarinic receptor stimulation. MYH14 drug alcohol 1591620 Electrophoretic analysis or these ethanol exposed fibroblast and myocyte cultures revealed specific reduction in the cellular contents of alpha actinin, myosin, and actin.

MPO drug alcohol 16046875 In rats challenged with K. pneumoniae, ethanol pretreatment significantly reduced BALF levels of CINC and MIP 2, suppressed alveolar neutrophil recruitment, and decreased whole lung myeloperoxidase activity. MPO drug alcohol 16046875 Alternatively, IT chemokine instillation partially restored BALF neutrophil recruitment but not whole lung myeloperoxidase activity in ethanol treated rats. MPO drug alcohol 9835289 Despite an increased bacterial burden in both the lung and liver at 24 hr after initiating E. coli infection in alcohol intoxicated animals, PMN tissue recruitment, indexed as myeloperoxidase activity, did not differ between control and alcohol treated rats.

DNMT1 drug alcohol 28433417 There is growing evidence that small molecule inhibitors of epigenetic modulators, such as histone deacetylases (HDAC) and DNA methyltransferases (DNMT), can reduce voluntary ethanol consumption in animal models, but molecular and cellular processes underlying this behavioral effect are poorly understood. DNMT1 drug alcohol 28433417 We used C57BL/6J male mice to investigate the effects of two FDA approved drugs, decitabine (a DNMT inhibitor) and SAHA (an HDAC inhibitor), on ethanol consumption using two tests: binge like drinking in the dark (DID) and chronic intermittent every other day (EOD) drinking.

DNMT1 drug opioid 27618384 Moreover, chronic morphine induced hypermethylation of GR 17 promoter may be at least partially due to the increase in hippocampal DNMT 1 expression and its binding at GR 17 promoter in the rat hippocampus. DNMT1 drug alcohol 26610727 Rats exposed to ELS were more sensitive to ethanol induced changes in Vglut expression in the VTA, Acb, and dStr and in Dnmt1 and Mecp2 expression in the striatal regions. DNMT1 drug opioid 26535894 The expression of proopiomelanocortin Pomc encoding β endorphin and Oprm1 encoding the mu opioid receptor were upregulated peripherally after incision; moreover, Oprm1 expression was further increased under DNMT inhibitor treatment. DNMT1 drug cocaine 26289919 Here, we investigated the role of DNMT activity in the reconsolidation of cocaine associated memories. DNMT1 drug cocaine 26289919 Bilateral intra basolateral amygdala (BLA) infusion of the DNMT inhibitor5 azacytidine (5 AZA, 1 μg per side) immediately following reactivation decreased subsequent reinstatement induced by cues or cocaine priming as well as cue maintained cocaine seeking behaviour.

DNMT1 drug alcohol 24968059 We investigated the effects of acute ethanol exposure on anxiety measures and function of histone deacetylases (HDAC) and DNA methyltransferases (DNMT) in the amygdala and bed nucleus of stria terminalis (BNST) of adolescent rats. DNMT1 drug alcohol 24968059 The lower dose of ethanol (1 g/kg) produced neither anxiolysis, nor inhibited the HDAC and DNMT activities in the amygdala and BNST, except DNMT activity in BNST was attenuated. DNMT1 drug alcohol 24968059 DNMT activity in the amygdala and BNST, and nuclear HDAC activity in the amygdala, but not in the BNST were also inhibited by these doses of ethanol. DNMT1 drug alcohol 24968059 A lack of tolerance was observed on ethanol induced inhibition of DNMT activity in the amygdala and BNST, and nuclear HDAC activity in the amygdala, as well to anxiolysis produced by ethanol (2 g/kg). DNMT1 drug alcohol 24968059 However, DNMT1 and DNMT3a expression in the BNST was increased, whereas DNMT3l mRNA was decreased in the amygdala, after 2 doses of 2 g/kg ethanol. DNMT1 drug alcohol 24968059 These results suggest that reduced sensitivity to anxiolysis and the lack of rapid tolerance to the anxiolytic effects of ethanol and inhibition of HDAC and DNMT functions may play a role in engaging adolescents in binge drinking patterns. DNMT1 addiction intoxication 24968059 These results suggest that reduced sensitivity to anxiolysis and the lack of rapid tolerance to the anxiolytic effects of ethanol and inhibition of HDAC and DNMT functions may play a role in engaging adolescents in binge drinking patterns. DNMT1 drug alcohol 24527678 Ethanol increased the gene expression of DNA methyltransferases (Dnmt1 and Dnmt3a), the corepressor Dnmt1 associated protein 1 (Dmap1), and the RNA methyltransferase Trdmt1. DNMT1 drug cocaine 23688924 Cocaine also increased DNMT3 expression, resulting in PP1Cβ repression that did not occur in the presence of DNMT inhibitor. DNMT1 drug alcohol 23423140 Specifically, we show that decreasing DNA methylation by inhibiting the activity of DNA methyltransferase (DNMT) with systemic administration of the FDA approved drug, 5 azacitidine (5 AzaC) prevents excessive alcohol use in mice. DNMT1 drug alcohol 23423140 Importantly, the actions of both DNMT and HDAC inhibitors are specific for alcohol, as no changes in saccharin or sucrose intake were observed. DNMT1 drug alcohol 23423140 In line with these behavioral findings, we demonstrate that excessive alcohol drinking increases DNMT1 levels and reduces histone H4 acetylation in the nucleus accumbens (NAc) of rodents. DNMT1 drug alcohol 23423140 Our study therefore highlights the possibility that DNMT and HDAC inhibitors can be used to treat harmful alcohol abuse. DNMT1 drug alcohol 23110077 Brains were then removed 30 min after a saline or 2 g/kg ethanol challenge to assess i) gene expression using PCR array targeting 84 epigenetic related genes and ii) histone deacetylases (HDAC), histone acetylases (HAT) and DNA methyltransferases (DNMT) activities as well as H4K12 acetylation. DNMT1 drug alcohol 23110077 Acute ethanol administration decreased dnmt1, esco2 and rps6ka5 genes expression. DNMT1 drug alcohol 23110077 Whereas global HAT or DNMT activity was not affected, global HDAC activity was reduced after an acute ethanol injection. DNMT1 drug cocaine 22438930 We also found that both mRNA and protein level of DNMT (DNA methytransferase) 3b in the PFC were downregulated following the establishment of cocaine CPP, and the downregulation could be reversed by repeated administration of methionine.

DNMT1 drug cocaine 20720536 We also found that pharmacological inhibition of DNMT by zebularine treatment decreased cocaine induced DNA hypermethylation at the PP1c promoter and attenuated PP1c mRNA downregulation in NAc. DNMT1 drug amphetamine 17254711 Methamphetamine alters expression of DNA methyltransferase 1 mRNA in rat brain. DNMT1 drug amphetamine 17254711 In the present study, we found subchronic methamphetamine treatment (4 mg/kg, i.p., once daily for 21 days) to induce different patterns of Dnmt1 mRNA expression in the nucleus caudatus and nucleus accumbens of two inbred rat strains, Fischer 344/N (increased Dnmt1) and Lewis/N (decreased Dnmt1).

CCS addiction addiction 32124022 These findings suggest that the high impulse behavioural expression in CCS addiction is associated with widespread brain regions, particularly within those in the frontal cortex. CCS drug nicotine 31711874 Switching to electronic cigarettes (ECs) may be a viable option to reduce the negative health effects for smokers who are unable or unwilling to quit smoking combustible cigarettes (CCs). CCS drug nicotine 31711874 Switching from CCs to ECs in HIV positive smokers who are not ready to quit smoking in the next 30 days appears to be feasible. CCS drug opioid 31677934 The higher a country's CCS, the better it was at managing opioid related health care issues. CCS drug nicotine 31582950 Positive perceptions of electronic cigarettes (e cigarettes) relative to combustible cigarettes (CCs) may erode support for endgame policies on CCs through smoking renormalization (increasing public acceptance of smoking). CCS drug nicotine 31582950 Multivariable regressions yielded adjusted odds ratios (AORs) of supporting endgame policies (individual policy items, all 5 policy items, at least 1 policy item, banning the sale/use of CCs) in relation to perceptions of e cigarettes relative to CCs, adjusting for age, education attainment, marital status, CC smoking status and ever e cigarette use. CCS addiction addiction 31582950 Few respondents perceived e cigarettes as more harmful (16.6%) or more addictive (9.3%) than CCs. CCS drug nicotine 31582950 Positive perceptions of e cigarettes (24.0%) were associated with less support for 'ban CC sales in 10 years if there is a product providing nicotine not made from tobacco' (AOR=0.62, 95% CI: 0.40 0.97), 'ban CC use when it's prevalence falls below 5%' (AOR=0.66, 95% CI: 0.44 0.98) and 'banning the sale of CCs' (AOR=0.63, 95% CI: 0.42 0.94).

CCS drug nicotine 30476301 ROS, carbonyl compounds (CCs), and total nicotine and its partitioning between free base and protonated forms were quantified in the IQOS aerosol by fluorescence, high performance liquid chromatography, and gas chromatography, respectively. CCS drug nicotine 30476301 For a given nicotine intake, inhalation exposure to ROS and CCs from IQOS is likely to be significantly less than that for combustible cigarettes. CCS drug nicotine 30416951 Participants in the present study were categorized as having 0, 1 2, or ≥3 smoking related chronic health conditions (i.e., chronic condition severity, CCS). CCS drug nicotine 30416951 Repeated measures analysis of variance was used to examine whether CCS moderated response to cigarettes across measures of addiction potential (i.e., concurrent choice testing between nicotine dose pairs, Cigarette Purchase Task (CPT) performance, positive subjective effects), tobacco withdrawal, cigarette craving, and smoking topography.

CCS addiction withdrawal 30416951 No main effects of CCS or interactions of CCS and nicotine dose were observed for concurrent choice testing, positive subjective effects, tobacco withdrawal, or smoking topography. CCS drug nicotine 30416951 There was an interaction of CCS and nicotine dose on Factor 1 of the Questionnaire on Smoking Urges with the effects of dose significant only among those with 1 2 chronic conditions. CCS drug nicotine 30126382 We aimed to investigate nicotine cessation for both ECs and CCs. CCS drug nicotine 30126382 Only 3.3% of observed users quit both ECs and CCs, whereas 20.5% quit smoking CCs. CCS drug nicotine 30126382 Quitting ECs and CCs was significantly higher among sole EC users (5 vs 2, respectively; OR: 5.62; P = 0.036) than it was among dual users, a result that was similar for CCs smoking (29 vs. 15; OR: 6.33; P ≤ 0.001). CCS drug opioid 29988765 Codeine containing cough syrups (CCS) have become one of the most popular drugs of abuse in young population worldwide. CCS addiction dependence 29988765 However, the neurobiological mechanisms underlying CCS dependence are yet ill defined.

CCS drug nicotine 27769828 A randomised, parallel group clinical study was performed to evaluate the safety profile of an e vapour product (EVP; 2.0% nicotine) in smokers of conventional cigarettes (CCs) switching to use the EVP for 12 weeks. CCS drug nicotine 27769828 The data presented here shows the potential EVPs may offer smokers looking for an alternative to CCs. CCS drug nicotine 27613951 Exposure measurements are required to determine whether it may be possible to reduce the individual health risk compared to smoking combustible cigarettes (CCs). CCS drug nicotine 27613951 THS 2.1 is a promising alternative to smoking CCs.

CCS addiction withdrawal 26662031 Decreased ALFFs in the left PoCG and left MOC were associated with decreased withdrawal syndrome severity in CCS dependent individuals. CCS addiction relapse 26618795 We hypothesized that within subject variation in EC use (yes/no each day) would be inversely associated with within subject variation in number of CCs consumed and craving during that same day. CCS addiction relapse 26618795 Participants completed EMA surveys throughout the day, which assessed CC craving, and end of day surveys, which assessed EC use and the number of CCs smoked that day.

CCS drug nicotine 22855882 In this study, we focused on a sample of 142 participants (mean age 19.54) that reported either smoking only tobacco cigarettes (CIG group, n = 70) or smoking both tobacco cigarettes and cannabis (CCS group, n = 72). CCS drug opioid 21477952 In recent years, codeine containing cough syrups (CCS) have been reported as substances of abuse, especially in adolescents. CCS addiction dependence 21477952 Chronic CCS abuse can induce physical and psychological dependence. CCS addiction dependence 21477952 Taken together, these results suggest that chronic CCS abuse may cause serious damage to the brain and the neuroimaging findings further illustrate the mechanism of CCS dependence.

CCS drug cocaine 1609038 The following demographic and study measures suggested favorable trends for study outcomes: older age, divorced status, higher pre treatment cocaine use, lower CCS scores, and lower self reports of cocaine use according to QCI. AIF1 drug cocaine 32278944 Consistently, we found elevated protein levels of Iba1, CCL2, TLR4 and mature IL1β in the striatum, not in the mPFc of cocaine receiving mice. AIF1 drug cannabinoid 32057593 In the mPFC and hippocampus, EtOH rats had significantly higher mRNA expression of endocannabinoid signaling (mPFC: Ppara, Dagla, Daglb and Napepld; and hippocampus: Cnr2, Dagla and Mgll) and neuroinflammation associated genes (mPFC: Gfap; and hippocampus: Aif1) than in controls. AIF1 drug cocaine 31998080 In parallel, cocaine self administration alone specifically and differentially affects activation of glial cells by decreasing GFAP expression in astrocytes but increasing Iba1 expression in microglia. AIF1 drug alcohol 31733666 Allograft Inflammatory Factor 1 mRNA was increased in both young and aged mice by alcohol exposure; however, only in the aged mice did the alcohol effect persist. AIF1 drug opioid 29729431 Pretreatment with 3mg/kg AM1241 decreased the chronic morphine induced Iba1 expression in spinal cord. AIF1 addiction withdrawal 28654797 Changes in brain gene expression levels of induced nitric oxide synthase (iNOS), astroglia marker, glial fibrillary acidic protein (GFAP), ionized calcium binding protein (Iba1) a microglia activation marker, a pro inflammatory mediator and tumor necrosis alpha (TNF α) were measured after withdrawal by real time polymerase chain reaction (RT PCR). AIF1 drug opioid 28654797 Administration of naloxone was associated with the increased expression of TNF α, GFAP, Iba1 and iNOS in the brain samples of morphine dependent mice, while the nine days treatment with both 5 and 10mg/kg simvastatin reduced such changes. AIF1 drug alcohol 28427424 Acute binge ethanol biphasically changed microglial (e.g., Iba1, CD68) gene expression, with initial decreases during intoxication and subsequent increases during withdrawal. AIF1 addiction intoxication 28427424 Acute binge ethanol biphasically changed microglial (e.g., Iba1, CD68) gene expression, with initial decreases during intoxication and subsequent increases during withdrawal. AIF1 addiction withdrawal 28427424 Acute binge ethanol biphasically changed microglial (e.g., Iba1, CD68) gene expression, with initial decreases during intoxication and subsequent increases during withdrawal. AIF1 addiction withdrawal 28062186 We attempted to verify withdrawal regulation of induced nitric oxide synthase (iNOS), astroglia marker, glial fibrillary acidic protein (GFAP), ionized calcium binding protein (Iba1), a microglia activation marker, a pro inflammatory mediator, tumor necrosis alpha (TNF α) and immune receptor, toll like receptor 4 (TLR 4) genes by real time polymerase chain reaction (RT PCR). AIF1 drug opioid 28062186 Brain expression levels of TNF α, GFAP, Iba1 and iNOS increased in morphine withdrawn animals which were attenuated by nine days treatment with atorvastatin. AIF1 drug opioid 27875800 Immunohistochemistry (IHC) experiments on striatal brain slices were performed to assess the expression of glial markers (Iba1, GFAP and CD68) during 14days after morphine discontinuation. AIF1 drug amphetamine 27098516 Using logistic regression models, we analyzed associations of Meth with cerebral gliosis (immunohistochemistry for ionized calcium binding adapter molecule 1 (Iba1) and glial fibrillary acidic protein (GFAP) in frontal, temporo parietal, and putamen internal capsule regions), synaptodendritic loss (confocal microscopy for synaptophysin (SYP) and microtubule associated protein 2 (MAP2) in frontal cortex), β amyloid plaque deposition (immunohistochemistry in frontal and temporo parietal cortex and putamen), and arteriolosclerosis (histopathology in forebrain white matter). AIF1 drug alcohol 27098516 We found that Meth was associated with marked Iba1 gliosis in the temporo parietal region (odds ratio, 4.42 (95 % confidence interval, 1.36, 14.39), p = 0.014, n = 62), which remained statistically significant after adjusting for HIV encephalitis, white matter lesions, and opportunistic diseases (n = 61); hepatitis C virus seropositivity (n = 54); and lifetime dependence on alcohol, opiates, and cannabis (n = 62). AIF1 drug amphetamine 27098516 We found that Meth was associated with marked Iba1 gliosis in the temporo parietal region (odds ratio, 4.42 (95 % confidence interval, 1.36, 14.39), p = 0.014, n = 62), which remained statistically significant after adjusting for HIV encephalitis, white matter lesions, and opportunistic diseases (n = 61); hepatitis C virus seropositivity (n = 54); and lifetime dependence on alcohol, opiates, and cannabis (n = 62). AIF1 drug cannabinoid 27098516 We found that Meth was associated with marked Iba1 gliosis in the temporo parietal region (odds ratio, 4.42 (95 % confidence interval, 1.36, 14.39), p = 0.014, n = 62), which remained statistically significant after adjusting for HIV encephalitis, white matter lesions, and opportunistic diseases (n = 61); hepatitis C virus seropositivity (n = 54); and lifetime dependence on alcohol, opiates, and cannabis (n = 62). AIF1 addiction dependence 27098516 We found that Meth was associated with marked Iba1 gliosis in the temporo parietal region (odds ratio, 4.42 (95 % confidence interval, 1.36, 14.39), p = 0.014, n = 62), which remained statistically significant after adjusting for HIV encephalitis, white matter lesions, and opportunistic diseases (n = 61); hepatitis C virus seropositivity (n = 54); and lifetime dependence on alcohol, opiates, and cannabis (n = 62). AIF1 drug opioid 26478469 The aim of the present study was to investigate the molecular effects of perinatal exposure to lead (Pb) on protein and mRNA expression of purine receptors: P2X4, P2X7, adenosine receptor A1; and astrocytes (GFAP mRNA expression) and on microglia activation (Iba1 mRNA expression) in several structures of the mesolimbic system (striatum, hippocampus, prefrontal cortex) in rats expressing tolerance to the antinociceptive effect of morphine. AIF1 drug nicotine 25637801 Nicotine also promoted elevations in the expression of glial fibrillary acidic protein (GFAP), a biomarker of activated astrocytes, and the microglia biomarker ionized calcium binding adapter molecule 1 (Iba1). AIF1 drug cannabinoid 24409127 Both acute and repeated cocaine exposure increased the number of cleaved caspase 3 , GFAP and Iba1 ir cells in the hippocampus, and this effect was counteracted by AM630 or Rimonabant, which increased the number of BrdU , GFAP , and Iba1 ir cells in the hippocampus. AIF1 drug cocaine 24409127 Both acute and repeated cocaine exposure increased the number of cleaved caspase 3 , GFAP and Iba1 ir cells in the hippocampus, and this effect was counteracted by AM630 or Rimonabant, which increased the number of BrdU , GFAP , and Iba1 ir cells in the hippocampus. AIF1 drug opioid 22362187 In the present study, by combining the techniques of in situ hybridization of MOR mRNA with immunohistochemistry of glial fibrillary acidic protein (GFAP; an astrocyte marker) and Iba1 (a microglial marker), we examined expression and distribution of GFAP, Iba1, and MOR mRNA in the spinal cord of rats under chronic morphine tolerance conditions. AIF1 drug opioid 22362187 Intrathecal injections of morphine twice daily for 7 days reduced morphine analgesic effect and increased both GFAP and Iba1 immunostaining densities in the spinal cord. AIF1 addiction sensitization 20035859 We also show that MA sensitization decreased LPS or acute MA induced microglial Iba1 expression compared to non sensitized mice. ADH1A drug alcohol 31870920 To answer these questions, we measured the expression and activity of alcohol dehydrogenase 1 (ADH1) and acetaldehyde dehydrogenase 2 (ALDH2) enzymes, ethanol and acetaldehyde levels in vivo, and binge like and preferential drinking behaviors with drinking in the dark and two bottle choice in animal models with liver injury. ADH1A addiction intoxication 31870920 To answer these questions, we measured the expression and activity of alcohol dehydrogenase 1 (ADH1) and acetaldehyde dehydrogenase 2 (ALDH2) enzymes, ethanol and acetaldehyde levels in vivo, and binge like and preferential drinking behaviors with drinking in the dark and two bottle choice in animal models with liver injury. ADH1A drug alcohol 31870920 In addition, chronic CCl4 and acute LPS treatment inhibited hepatic ADH1 expression and activity, leading to increases in blood and liver ethanol concentrations. ADH1A drug alcohol 31648290 In this paper, we demonstrate the efficient recruitment of pyruvate decarboxylase (Pdc1) and alcohol dehydrogenase (Adh1) fermentation enzymes into the viral replication compartment. ADH1A drug alcohol 31018006 Then, alcohol dehydrogenase (ADH1) and aldehyde dehydrogenase (ALDH2) protein levels and enzymatic activities in the livers were quantified. ADH1A drug alcohol 31018006 The studies show that treatment with fenofibrate not only increased the activity of catalase in the liver of alcohol drinking rats, as reported earlier, but also increased the levels and enzymatic activity of ADH1, while ALDH2 remained unchanged. ADH1A drug alcohol 31018006 The increases in ADH1 contribute to explaining the remarkable effect of fenofibrate in raising blood levels of acetaldehyde in ethanol consuming animals, in which a marked reduction of alcohol intake is recorded. ADH1A drug alcohol 31018006 Tras eso, se midieron los niveles hepáticos y actividades enzimáticas de alcohol deshidrogenasa (ADH1) y de aldehído deshidrogenasa (ALDH2). ADH1A drug alcohol 31018006 Los resultados muestran que el tratamiento con fenofibrato no solo aumenta la actividad de catalasa en el hígado de ratas bebedoras de alcohol, sino que también incrementa los niveles y la actividad de ADH1, sin alterar ALDH2. ADH1A drug alcohol 31002879 The association between alcohol metabolism and genetic variants of ADH1A, SRPRB, and PGM1 in Korea. ADH1A drug alcohol 31002879 We identified variations in the ADH1A, SRPRB, and PGM1 genes, which are directly associated with blood alcohol or acetaldehyde concentrations. ADH1A drug alcohol 31002879 Namely, the T allele of SRPRB rs17376019 and the C allele of PGM1 rs4643 were associated with lower blood alcohol levels, while the ADH1 rs1229976 C allele group exhibited markedly higher blood acetaldehyde levels than those of the ADH1 rs1229976 T allele group. ADH1A drug alcohol 31002879 This study demonstrates that genetic variations in ADH1A, SRPRB, and PGM1 are associated with variations in blood alcohol and acetaldehyde concentration after alcohol intake. ADH1A drug alcohol 30470859 Gene expression of enzymes involved in the metabolism of ethanol, i.e., Adh1 and Aldh2, were altered by hypothyroidism and T4/T3 supplementation. ADH1A drug alcohol 29431616 Pxr null mice displayed higher basal mRNA levels of hepatic lipogenic transcription factor sterol regulatory element binding protein 1c (Srebp 1c) and its target stearoyl CoA desaturase 1 (Scd1) and the lipid peroxide detoxifying aldo keto reductase 1b7 (Akr1b7) and higher protein levels of EtOH metabolizing alcohol dehydrogenase 1 (ADH1). ADH1A addiction intoxication 29431616 In contrast, Pxr null mice displayed increased Akr1b7 gene and ADH1 protein expression and hypertriglyceridemia following binge EtOH exposure. ADH1A drug alcohol 28815635 In this study, we assessed sequencing variants in the ADH genomic region (ADH1 7) and tested for their associations with AUD phenotypes in 2 independent populations: an American Indian (AI) community sample and an EA cohort from the San Francisco Family Alcohol Study. ADH1A drug alcohol 28810607 Intriguingly, 1% ethanol intake remarkably elevated (10 fold, P<0.05) mRNA of brain alcohol dehydrogenase 1 (Adh1), which metabolizes lipid peroxidation products and is involved in the synthesis of retinoic acid, a neuroprotective factor. ADH1A drug alcohol 27538709 Chronic plus binge ethanol exposure increased the expression of ADH1 and CYP2E1. ADH1A addiction intoxication 27538709 Chronic plus binge ethanol exposure increased the expression of ADH1 and CYP2E1. ADH1A drug alcohol 25270064 We assessed ancestry admixture and tested for associations between alcohol related phenotypes in the genomic regions around the ADH1 7 and ALDH2 and ALDH1A1 genes. ADH1A drug alcohol 23847486 Gene specific modifications reviewed here show that an increased liver generation of acetaldehyde (by transduction of a gene coding for a high activity liver alcohol dehydrogenase ADH1(*)B2) leads to increased blood acetaldehyde levels and aversion to ethanol in animals. ADH1A addiction aversion 23847486 Gene specific modifications reviewed here show that an increased liver generation of acetaldehyde (by transduction of a gene coding for a high activity liver alcohol dehydrogenase ADH1(*)B2) leads to increased blood acetaldehyde levels and aversion to ethanol in animals. ADH1A drug alcohol 23468174 Humans express at least seven alcohol dehydrogenase (ADH) isoforms that are encoded by ADH gene cluster (ADH7 ADH1C ADH1B ADH1A ADH6 ADH4 ADH5) at chromosome 4. ADH1A drug alcohol 20828554 The ethanol elimination rate is regulated by alcohol metabolizing enzymes, primarily alcohol dehydrogenase (ADH1), acetaldehyde dehydrogenase (ALDH), and cytochrome P450 (CYP2E1). ADH1A drug alcohol 20617019 The conventional view is that alcohol metabolism is carried out by ADH1 (Class I) in the liver. ADH1A drug alcohol 20617019 Over the past three decades, vigorous attempts to identify the enzyme responsible for the non ADH1 pathway have focused on the microsomal ethanol oxidizing system (MEOS) and catalase, but have failed to clarify their roles in systemic alcohol metabolism. ADH1A drug alcohol 20617019 When various doses of ethanol are administered to mice, liver ADH3 activity is dynamically regulated through induction or kinetic activation, while ADH1 activity is markedly lower at high doses (3 5 g/kg). ADH1A drug alcohol 20617019 These data suggest that ADH3 plays a dynamic role in alcohol metabolism, either collaborating with ADH1 or compensating for the reduced role of ADH1. ADH1A drug alcohol 20617019 A complex two ADH model that ascribes total liver ADH activity to both ADH1 and ADH3 explains the dose dependent changes in the pharmacokinetic parameters (beta, CL(T), AUC) of blood ethanol very well, suggesting that alcohol metabolism in mice is primarily governed by these two ADHs. ADH1A drug alcohol 20617019 In patients with alcoholic liver disease, liver ADH3 activity increases, while ADH1 activity decreases, as alcohol intake increases. ADH1A drug alcohol 20617019 These data suggest that chronic binge drinking and the resulting liver disease shifts the key enzyme in alcohol metabolism from low K(m) ADH1 to high K(m) ADH3, thereby reducing the rate of alcohol metabolism. ADH1A addiction intoxication 20617019 These data suggest that chronic binge drinking and the resulting liver disease shifts the key enzyme in alcohol metabolism from low K(m) ADH1 to high K(m) ADH3, thereby reducing the rate of alcohol metabolism. ADH1A drug alcohol 20617019 The interdependent increase in the ADH3/ADH1 activity ratio and AUC may be a factor in the development of alcoholic liver disease. ADH1A addiction dependence 19526455 ADH1A variation predisposes to personality traits and substance dependence. ADH1A drug alcohol 19526455 Recently, significant associations between alcohol dehydrogenase type 1A gene (ADH1A) and SD have been reported, which led us to investigate the impact of ADH1A variation on personality traits and risk of SD. ADH1A drug alcohol 19489444 Alcohol metabolism is known to be mainly carried out by the classic ADH1 (Class I) of the liver. ADH1A drug alcohol 19489444 Over the past three decades, vigorous attempts to identify the enzyme responsible for the non ADH1 pathway have focused on the microsomal oxidizing system (MEOS) and catalase, but have failed to clarify their roles in systemic alcohol metabolism. ADH1A drug alcohol 19489444 By acute administrations of ethanol to mice at various doses, liver ADH3 activity was dynamically regulated through induction or kinetic activation, though ADH1 activity was markedly decreased at higher doses (3 5 g/kg). ADH1A drug alcohol 19489444 These data suggest that ADH3 plays a dynamical share in alcohol metabolism with ADH1, collaborating with it or supplementing the decreased role of ADH1. ADH1A drug alcohol 19489444 The two ADH complex model, which ascribes total liver ADH activity to both ADH1 and ADH3, explained well the dose dependent changes in pharmacokinetic parameters (beta, CL(T), AUC) of blood ethanol, suggesting that alcohol metabolism in mice is primarily governed by the two ADHs. ADH1A drug alcohol 19489444 In patients with alcoholic liver diseases, the liver ADH3 activity increased but the ADH1 activity decreased with an increase in alcohol intake. ADH1A drug alcohol 19489444 These data suggest that heavy and chronic drinking shifts the main enzyme in alcohol metabolism from low Km ADH1 to high Km ADH3 to develop alcoholic liver diseases by the nonlinear increase in AUC due to the decrease of the metabolic rate. ADH1A drug alcohol 19193628 Alleles of ADH7 SNPs were associated with the early stages of alcohol metabolism, with additional effects in the ADH1A, ADH1B and ADH4 regions. ADH1A drug alcohol 16571603 Haplotype tag SNPs were selected for the block in the ADH4 gene that provided evidence of association and subsequently used in association analysis; the haplotype was significantly associated with alcoholism (P=0.01) There was weaker evidence that variations in ADH1A and ADH1B might also play a role in modifying risk. ADH1A drug alcohol 16431092 Alcohol metabolism in vivo cannot be explained solely by the action of the classical alcohol dehydrogenase, Class I ADH (ADH1). ADH1A drug alcohol 16431092 Over the past three decades, attempts to identify the metabolizing enzymes responsible for the ADH1 independent pathway have focused on the microsomal ethanol oxidizing system (MEOS) and catalase, but have failed to clarify their roles in systemic alcohol metabolism. ADH1A drug alcohol 12095699 Distal and proximal cis linked sequences are needed for the total expression phenotype of the mouse alcohol dehydrogenase 1 (Adh1) gene. ADH1A drug alcohol 12095699 Mouse alcohol dehydrogenase 1 (Adh1) gene expression occurs at high levels in liver and adrenal, moderate levels in kidney and intestine, low levels in a number of other tissues, and is undetectable in thymus, spleen and brain by Northern analysis. ADH1A drug alcohol 11960985 Here we have examined mice for the effect of either acute ethanol intoxication or Adh1 gene disruption on RA synthesis and degradation. ADH1A addiction intoxication 11960985 Here we have examined mice for the effect of either acute ethanol intoxication or Adh1 gene disruption on RA synthesis and degradation. ADH1A drug alcohol 11960985 RA produced in Adh1 null mutant mice following a 50 mg/kg dose of retinol was reduced 82% relative to wild type mice, thus similar to wild type mice pretreated with ethanol. ADH1A drug alcohol 11960985 Reduced RA production was associated with increased retinol levels in both ethanol treated wild type mice and Adh1 null mutant mice, indicating reduced clearance of the retinol dose. ADH1A drug alcohol 11960985 RA degradation following a dose of RA (10 mg/kg) was increased only 42% by ethanol pretreatment (3.5 g/kg) and only 26% in Adh1 null mutant mice relative to wild type mice. ADH1A drug alcohol 11253427 Repetitive gametic selection for a higher frequency of the Adh1 S semilethal mutant allele of the alcohol dehydrogenase (ADH) gene yielded viable homozygotes Adh1 SS. TUBB4A drug alcohol 7515684 Four of thes are the same types of double helices as previously found in ethanol (i.e., a symmetric left handed parallel beta 5.6 double helix, an unsymmetric left handed parallel beta 5.6 double helix, a symmetric left handed antiparallel beta 5.6 double helix, a symmetric right handed parallel beta 5.6 double helix); the fifth is possibly a symmetric right handed antiparallel beta 5.6 double helix. PPARG drug alcohol 32445052 Proinflammatory processes have been implicated in alcohol addiction, craving, and relapse, while studies in experimental animals have suggested that activation of peroxisome proliferator activated receptor gamma (PPARγ) inhibits proinflammatory signaling. PPARG addiction addiction 32445052 Proinflammatory processes have been implicated in alcohol addiction, craving, and relapse, while studies in experimental animals have suggested that activation of peroxisome proliferator activated receptor gamma (PPARγ) inhibits proinflammatory signaling. PPARG addiction relapse 32445052 Proinflammatory processes have been implicated in alcohol addiction, craving, and relapse, while studies in experimental animals have suggested that activation of peroxisome proliferator activated receptor gamma (PPARγ) inhibits proinflammatory signaling. PPARG drug alcohol 30195735 Among them, drugs interacting with acylethanolamide receptors including cannabinoid CB1 receptor antagonists/inverse agonists, peroxisome proliferator activated receptor alpha (PPARα) agonists or peroxisome proliferator activated receptor gamma (PPARγ) agonists have demonstrated utility in the reduction of alcohol intake in animal models. PPARG drug cannabinoid 30195735 Among them, drugs interacting with acylethanolamide receptors including cannabinoid CB1 receptor antagonists/inverse agonists, peroxisome proliferator activated receptor alpha (PPARα) agonists or peroxisome proliferator activated receptor gamma (PPARγ) agonists have demonstrated utility in the reduction of alcohol intake in animal models. PPARG drug alcohol 28220523 Peroxisome proliferator activated receptor gamma (PPARγ) plays a complex role in lipid metabolism and inflammation; therefore, the purpose of this study was to dissect its role in regulating steatosis and neutrophil infiltration in a clinically relevant mouse steatohepatitis model of 3 month high fat diet (HFD) feeding plus a binge of ethanol (HFD plus binge ethanol). PPARG addiction intoxication 28220523 Peroxisome proliferator activated receptor gamma (PPARγ) plays a complex role in lipid metabolism and inflammation; therefore, the purpose of this study was to dissect its role in regulating steatosis and neutrophil infiltration in a clinically relevant mouse steatohepatitis model of 3 month high fat diet (HFD) feeding plus a binge of ethanol (HFD plus binge ethanol). PPARG drug alcohol 28220523 Hepatocyte specific Pparg disruption reduced liver steatosis but surprisingly increased hepatic neutrophil infiltration after HFD plus binge ethanol. PPARG addiction intoxication 28220523 Hepatocyte specific Pparg disruption reduced liver steatosis but surprisingly increased hepatic neutrophil infiltration after HFD plus binge ethanol. PPARG drug alcohol 28220523 Moreover, hepatocyte specific deletion of the Pparg gene, but not the fat specific protein 27 gene, markedly up regulated hepatic levels of the gene for chemokine (C X C motif) ligand 1 (Cxcl1, a chemokine for neutrophil infiltration) in HFD plus binge ethanol fed mice. PPARG addiction intoxication 28220523 Moreover, hepatocyte specific deletion of the Pparg gene, but not the fat specific protein 27 gene, markedly up regulated hepatic levels of the gene for chemokine (C X C motif) ligand 1 (Cxcl1, a chemokine for neutrophil infiltration) in HFD plus binge ethanol fed mice. PPARG drug cocaine 27939396 A Role for Peroxisome Proliferator Activated Receptor Gamma Coactivator 1α in Nucleus Accumbens Neuron Subtypes in Cocaine Action. PPARG drug cocaine 27939396 Molecules critically involved in cocaine behavioral plasticity are known to regulate and interact with peroxisome proliferator activated receptor gamma coactivator 1α (PGC 1α). PPARG drug opioid 27714428 We recently demonstrated that activation of peroxisome proliferator activated receptor gamma (PPARγ) by pioglitazone reduces the motivation for heroin and attenuates its rewarding properties. PPARG drug alcohol 26968209 The ethanol feeding induced liver fat accumulation and mRNA expression of hepatic Pparg2 in WT mice, which suggests that a high level of PPARγ2 is a common driving force for fat accumulation induced by ethanol or a high fat diet. PPARG drug alcohol 26968209 Interestingly, ethanol fed SHP( / ) mice displayed hepatic fat accumulation similar to that of ethanol fed WT mice, even though their Pparg2 expression level remained lower.

KCNJ6 addiction dependence 18400906 Our data suggest that inhibition of adrenergic tone is required for the induction of dependence, and that channels containing GIRK2 and GIRK3 serve as an inhibitory gate. KCNJ6 drug opioid 17368966 In a functional assay system comprised of MOR 1 mu opioid receptors and GIRK2 potassium channels expressed in Xenopus oocytes, lobeline had no effect on the resting current, but maximally inhibited (IC(50)=1.1 microM) morphine and DAMGO activated potassium current in a concentration dependent manner.

KCNJ6 drug alcohol 12721779 Previous studies have shown that GIRK2 channel function is enhanced by ethanol and that GIRK2 null mutant mice are less sensitive to some of ethanol's effects, including anxiolysis, habituated locomotor stimulation, and acute handling induced convulsions than wild types. KCNJ6 drug alcohol 12721779 Under some conditions, GIRK2 knockout mice consume more ethanol than wild types, but it is unclear whether they do so because they are more sensitive to ethanol's rewarding effects or less sensitive to its aversive effects.

KCNJ6 drug alcohol 11454913 Potassium channels as targets for ethanol: studies of G protein coupled inwardly rectifying potassium channel 2 (GIRK2) null mutant mice. KCNJ6 drug alcohol 11454913 Selective enhancement of GIRK2 function by intoxicating concentrations of ethanol was recently shown for recombinant homomeric and heteromeric channels. KCNJ6 drug alcohol 11454913 We proposed that specific behavioral actions of ethanol are due to activation of GIRK channels and that these behaviors would be reduced or eliminated in GIRK2 null mutant ("knockout") mice. KCNJ6 drug alcohol 11454913 In the absence of ethanol, GIRK2 knockout mice showed more motor activity, less anxiety, and higher HIC. KCNJ6 drug alcohol 11454913 These results provide evidence that GIRK2 channels mediate specific behaviors, including anxiety and convulsions, and may influence effects of ethanol on these behaviors. HSPA4 addiction reward 32446966 Significantly upregulated expression of immune related genes (anti lipopolysaccharide factors (alf), peroxiredoxin (prx5), cathepsin B (ctsb), mitochondrial manganese superoxide dismutase (mtMnsod), cyclophilin A (cypa), glutathione peroxidase (gpx), Toll like receptor 3 (tlr3), and heat shock protein 70 (hsp70)) was detected in the crayfish fed the diets supplemented with 0.15% and 0.20% CPP diet compared with the levels observed in the control crayfish. HSPA4 drug opioid 30497790 Recombinant Mycobacterium tuberculosis Hsp70 was appended with heroin haptens and the resulting immunoconjugate granted anti heroin antibody production and blunted heroin induced antinociception. HSPA4 drug opioid 30497790 Moreover, Hsp70 as a carrier protein surpassed our benchmark Her KLH cocktail through antibody mediated blockade of 6 acetylmorphine, the main mediator of heroin's psychoactivity. HSPA4 drug opioid 26907924 Protein expression of HSP70, HSP105, and Vcp in the Heroin+acupuncture and Heroin+methadone groups was significantly higher than the Heroin group (p<0.01). HSPA4 drug opioid 26907924 The positive effects of acupuncture on brain damage caused by heroin may be closely related to up regulation of HSP70, HSP105, and Vcp, and reduced apoptosis.

HSPA4 addiction sensitization 26728895 In contrast, the unpaired morphine treated group failed to exhibit behavioral sensitization or higher Hsp70 expression. HSPA4 addiction sensitization 26728895 Additionally, by adding a habituation process prior to the challenge, we demonstrated that conditioned hyperactivity, which was not accompanied by an increased expression of Hsp70, is not essential for behavioral sensitization. HSPA4 addiction sensitization 26728895 Furthermore, alterations in Hsp70 expression in the NAc may represent a neurobiological sensitization mechanism mediating context and time dependent behavioral sensitization. HSPA4 drug opioid 26377394 We demonstrated increased levels of hsp70 and BiP expression as well as phosphorylation of eIF2α in various rat brain areas after oxycodone administration. HSPA4 drug alcohol 25024384 Moderate alcohol induces stress proteins HSF1 and hsp70 and inhibits proinflammatory cytokines resulting in endotoxin tolerance. HSPA4 drug alcohol 25024384 In this study, we show that cellular stress proteins HSF1 and hsp70 play a mechanistic role in alcohol mediated inhibition of the TLR4/MyD88 pathway. HSPA4 drug alcohol 25024384 Furthermore, HSF1 target gene hsp70 mRNA and protein are upregulated by alcohol in monocytes. HSPA4 drug alcohol 25024384 Furthermore, association of hsp70 with NF κB subunit p50 in alcohol treated macrophages correlates with reduced NF κB activation at later time points. HSPA4 drug alcohol 25024384 Hsp70 overexpression in macrophages was sufficient to block LPS induced NF κB promoter activity, suggesting alcohol mediated immunosuppression by hsp70. HSPA4 drug alcohol 25024384 The direct crosstalk of hsp70 and HSF1 was further confirmed by the loss of alcohol mediated endotoxin tolerance in hsp70 and HSF1 silenced macrophages. HSPA4 drug alcohol 25024384 Our data suggest that alcohol mediated activation of HSF1 and induction of hsp70 inhibit TLR4 MyD88 signaling and are required for alcohol induced endotoxin tolerance.

HSPA4 addiction sensitization 24280010 Finally, both the functional inhibition of Hsp70 ATPase activity by methylene blue (MB), and the antagonism of Hsp70 substrate binding site (SBD) activity by pifithrin μ (PES) impaired the development of behavioural sensitization when they were microinjected into the NAc core.

HSPA4 drug alcohol 20488642 Ethanol increases HSP70 concentrations in honeybee (Apis mellifera L.) brain tissue. HSPA4 drug alcohol 20488642 The purpose of this study was to evaluate whether ethanol doses that affect honeybee behavior also induce a significant stress response, measured by heat shock protein 70 (HSP70) concentrations, in honeybee brain tissues. HSPA4 drug alcohol 20488642 Experiment 2 investigated the relationship between ethanol dose and brain HSP70 concentrations. HSPA4 drug alcohol 20488642 Bees in ethanol treatments were fed 1.5M sucrose (control) and 1.5M sucrose ethanol solutions containing 2.5, 5, and 10% ethanol, allowed to sit for 4h, and dissected brains were assayed for HSP70. HSPA4 drug alcohol 20488642 We observed ethanol induced increases in honeybee brain HSP70 concentrations from the control group through the 5% ethanol group. HSPA4 drug alcohol 20488642 Only bees in the 5% ethanol group had HSP70 concentrations significantly higher than the control group. HSPA4 drug alcohol 20488642 The inverted U shaped ethanol dose HSP70 concentration response curve indicated that ingestion of 2.5% ethanol and 5% ethanol stimulated the stress response, whereas ingestion of 10% ethanol inhibited the stress response. HSPA4 drug alcohol 20488642 Doses that show maximum HSP70 concentration (5% ethanol) or HSP70 inhibition (10% ethanol) correspond to those (> or =5% ethanol) that also impaired honeybees in previous studies.

HSPA4 drug alcohol 16410189 This study examined Hsp70 accumulation and the subcellular characteristics of liver and lung when exposed to ethanol (EtOH), with and without L carnitine protection. HSPA4 drug alcohol 16317704 Alcohol administration to ob/ob mice did not increase oxidative stress despite increased CYP2E1, but increased plasma TNF alpha, further increased Hsp70, and profoundly decreased p65 nuclear factor kappaB (NF kappaB) protein and DNA binding activity in nuclear extracts. HSPA4 drug alcohol 15976529 At three days of ethanol withdrawal, we found region specific and sex selective alterations in levels of GAD (glutamic acid decarboxylase, GABA synthetic enzyme), GABA and glutamate transporters, and the synapse associated proteins HSP70, PSD 95, and synaptophysin.

HSPA4 drug opioid 15379885 After 30 days of forced abstinence from morphine self administration, abundance of hsp70 and lysozyme returned to basal levels. HSPA4 drug opioid 15379885 Additionally, acute as well as chronic intraperitoneal morphine administration changed the abundance of PKC gamma, gamma1 subunit of GABAA and hsp70 genes. HSPA4 drug alcohol 11917132 Here we show that the aerobic growth ability on ethanol depends also on protection of the mutant AdhE against metal catalyzed oxidation by the chaperone DnaK (a member of the Hsp70 family). HSPA4 drug alcohol 9626570 In the present study we measured in various brain areas and in liver the intracellular levels of HSP70 proteins, sulfhydryl groups and the antioxidant enzyme status after chronic administration of mild intoxicating doses of ethanol to rats. HSPA4 drug alcohol 9626570 Expression of HSP70 in response to alcohol administration was particularly high in the hippocampus and striatum. HSPA4 drug alcohol 9626570 This study agrees with our previous results performed on acute alcohol intoxication and supports the hypothesis that HSP70 induction protects the different brain areas against oxidative stress.

HSPA4 drug alcohol 1989992 Regulation of Hsc70 by 50 200 mM ethanol appeared to be a specific change in expression of an ethanol responsive gene rather than a typical stress protein response since no induction of the highly inducible stress protein, Hsp70, was seen at these ethanol concentrations.

HCRT drug alcohol 31394141 In rodents and zebrafish, our studies show that embryonic exposure to low dose ethanol, in addition to increasing voluntary ethanol intake during adolescence, increases the density of hypothalamic hypocretin (hcrt) neurons, a neuropeptide known to regulate reward related behaviors. HCRT addiction reward 31394141 In rodents and zebrafish, our studies show that embryonic exposure to low dose ethanol, in addition to increasing voluntary ethanol intake during adolescence, increases the density of hypothalamic hypocretin (hcrt) neurons, a neuropeptide known to regulate reward related behaviors. HCRT drug alcohol 31394141 To determine if preconception maternal ethanol consumption also affects these hcrt neurons and behavior in the offspring, we first standardized a method of measuring voluntary ethanol consumption in AB strain adult and larval zebrafish given gelatin meals containing 10% or 0.1% ethanol, respectively. HCRT drug alcohol 31394141 Whereas ethanol consumption by adult female HuC:GFP transgenic zebrafish had no impact on the number of differentiated HuC+ neurons at 28 h post fertilization (hpf), preconception ethanol consumption by adult female hcrt:EGFP zebrafish significantly increased the number of hcrt neurons in the offspring, an effect observed at 28 hpf and confirmed at 6 and 12 days post fertilization (dpf). HCRT drug alcohol 31394141 This increase in hcrt neurons was primarily present on the left side of the brain, indicating asymmetry in ethanol's actions, and it was accompanied by behavioral changes in the offspring, including a significant increase in novelty induced locomotor activity but not thigmotaxis measured at 6 dpf and also in voluntary consumption of 0.1% ethanol gelatin at 12 dpf. HCRT drug alcohol 31394141 Notably, these measures of ethanol intake and locomotor activity stimulated by preconception ethanol were strongly, positively correlated with the number of hcrt neurons. HCRT drug alcohol 31394141 These findings demonstrate that preconception maternal ethanol consumption affects the brain and behavior of the offspring, producing effects similar to those caused by embryonic ethanol exposure, and they provide further evidence that the ethanol induced increase in hcrt neurogenesis contributes to the behavioral disturbances caused by ethanol. HCRT addiction reward 31206717 With zebrafish having marked advantages for elucidating neural mechanisms underlying brain disorders, we recently tested and showed in these fish, similar to rodents, that low dose embryonic EtOH stimulates voluntary consumption of EtOH while increasing expression of hypocretin/orexin (hcrt) neurons, a neuropeptide that promotes consummatory and reward related behaviors. HCRT addiction relapse 30796894 In the early 2000s, hcrt/ox transmission was shown to underlie mating behavior in male rats suggesting a novel role in reward seeking. HCRT addiction reward 30796894 In the early 2000s, hcrt/ox transmission was shown to underlie mating behavior in male rats suggesting a novel role in reward seeking. HCRT drug cocaine 30796894 Soon thereafter, hcrt/ox neurons were shown to respond to drug associated stimuli, and hcrt/ox transmission was found to facilitate motivated responding for intravenous cocaine. HCRT addiction relapse 30796894 Notably, blocking hcrt/ox transmission using systemic or site directed pharmacological antagonists markedly reduced motivated drug taking as well as drug seeking in tests of relapse. HCRT drug cocaine 30796894 This review will unfold the current state of knowledge implicating hcrt/ox receptor transmission in the context of cocaine abuse and provide detailed background on animal models and underlying midbrain circuits. HCRT drug cocaine 30796894 The review will conclude with discussion of recent preclinical studies assessing utility of suvorexant the first and only FDA approved hcrt/ox receptor antagonist against cocaine associated behaviors. HCRT drug alcohol 30293056 The current study used an animal model that combined an intermittent pattern of alcohol vapor exposure with voluntary drinking of 20% unsweetened alcohol in adolescent male and female Wistar rats (postnatal day [PD] 22 62), in order to test for potential differences in behavioral changes, ethanol drinking, and hypocretin/orexin (Hcrt/OX) signaling associated with exposure status. HCRT drug alcohol 30293056 Histological results indicated that adolescent alcohol did not alter Hcrt/OX 1 or Hcrt/OX 2 receptor mRNA expression levels in adult rats compared to control adults. HCRT drug alcohol 30293056 These data suggest that our current model of intermittent ethanol exposure in adolescence can modestly affect both behavior and future consumption of alcohol and that Hcrt/OX receptor signaling differs between males and females. HCRT addiction reward 29703996 The hypocretin/orexin (HCRT) neuropeptide system regulates feeding, arousal state, stress responses, and reward, especially under conditions of enhanced motivational relevance. HCRT addiction relapse 29703996 In particular, HCRT neurotransmission facilitates drug seeking behavior in circumstances that demand increased effort and/or motivation to take the drug. HCRT drug cocaine 29703996 The present study used a shRNA encoding adeno associated viral vector to knockdown Hcrt expression throughout the dorsal hypothalamus in adult rats and determine the role of HCRT in cocaine self administration. HCRT drug cocaine 29703996 Chronic Hcrt silencing did not impact cocaine self administration under short access conditions, but robustly attenuated cocaine intake under extended access conditions, a model that mimics key features of compulsive cocaine taking.

GABPA drug nicotine 28641491 Nicotine and cigarette smoke modulate Nrf2 BDNF dopaminergic signal and neurobehavioral disorders in adult rat cerebral cortex. GABPA drug alcohol 28501008 Ethanol extract and its dichloromethane fraction of Alpinia oxyphylla Miquel exhibited hepatoprotective effects against CCl4 induced oxidative damage in vitro and in vivo with the involvement of Nrf2. GABPA drug amphetamine 26427884 We investigated whether Nrf2 is activated by methamphetamine (METH) thereby altering neurotoxicity in Nrf2 +/+ and / adult mouse brain. GABPA drug amphetamine 26427884 A single dose of METH can induce the mRNA levels of Nrf2 regulated antioxidant and cytoprotective proteins in mouse brain. GABPA drug amphetamine 26427884 These Nrf2 dependent effects were independent of changes in METH metabolism or the induction of hyperthermia. GABPA drug amphetamine 26427884 Nrf2 mediated pathways accordingly may protect against the neurodegenerative effects and functional deficits initiated by METH and perhaps other reactive oxygen species enhancing neurotoxicants, when there is time for transcriptional activation and protein induction. GABPA drug amphetamine 26427884 In human users of METH, this mechanism may be essential when differences in drug abuse patterns may alter the induction and duration of Nrf2 activation thereby modulating susceptibility to the neurotoxic effects of METH.

GABPA drug alcohol 24060752 Sulforaphane induces Nrf2 and protects against CYP2E1 dependent binge alcohol induced liver steatosis. GABPA addiction intoxication 24060752 Sulforaphane induces Nrf2 and protects against CYP2E1 dependent binge alcohol induced liver steatosis. GABPA drug alcohol 24060752 The current study was designed to evaluate the ability of sulforaphane, an activator of Nrf2, to blunt CYP2E1 dependent, ethanol induced steatosis in vivo and in vitro. GABPA drug alcohol 24060752 The sulforaphane treatment activated Nrf2, increased levels of the Nrf2 target heme oxygenase 1 and subsequently lowered oxidant stress as shown by the decline in lipid peroxidation and 3 nitrotyrosine protein adducts and an increase in GSH levels after the acute ethanol treatment. GABPA drug alcohol 24060752 Similar results were found in vitro as addition of sulforaphane to HepG2 E47 cells, which express CYP2E1, elevated Nrf2 levels and decreased the accumulation of lipid in cells cultured with ethanol. GABPA addiction addiction 24024172 In this study we show that activation of Nrf2, either by the small molecule sulforaphane or knockout of the Nrf2 inhibitor Keap1, leads to increased cellular glucose uptake and increased glucose addiction in fibroblasts. GABPA drug amphetamine 22903344 Moreover, our results also show that METH downregulated another transcription factor, the nuclear factor erythroid 2 related factor (Nrf2), a transcription factor implicated in the expression of several antioxidant/detoxificant enzymes. GABPA drug amphetamine 22903344 These results demonstrate, for the first time, that METH directly induces inflammation in neurons via an NF κB dependent pathway and that the anti neuroinflammatory effects of melatonin result from the inhibition of activated NF κB in parallel with potentiated antioxidant/detoxificant defense by activated Nrf2 pathway. GABPA drug nicotine 22686525 Nrf2: friend and foe in preventing cigarette smoking dependent lung disease. GABPA addiction dependence 22686525 This chemical trait is virtually predestined to be sensitized by the major route leading to Nrf2 activation, characterized by its dependence on the interaction of electrophiles with specific cysteine residues inherited by Nrf2's negative cytosolic regulator Keap1 (Kelch like ECH associated protein 1). GABPA drug nicotine 22686525 In terms of the two major smoking related diseases of the lung, that is, emphysema and lung cancer, a fully functional Nrf2 genotype seems to be necessary, although not sufficient by itself, to protect the smoker from acquiring emphysema. GABPA drug nicotine 22686525 Contrasting with this protective role, however, Nrf2 function may be potentially fatal in smoking related lung tumorigenesis: as concluded from recent clinical investigations, lung tumor tissues harbor increased mutation or, alternatively, aberrant expression rates in either the KEAP1 or the NRF2 gene, generally resulting in constitutive Nrf2 activation, suggesting that "abuse" of Nrf2 function is an advantageous strategy of the (developing) tumor to protect itself against oxidative stress in general. GABPA drug nicotine 22686525 On the basis of the fundamental significance of the Nrf2 pathway in smoking dependent disease development, several attempts have been described for dietary and pharmacological intervention, the majority of which are intended to activate Nrf2 aiming at emphysema prevention. GABPA drug alcohol 22552773 Ethanol induction of CYP2A5: role of CYP2E1 ROS Nrf2 pathway. GABPA drug alcohol 22552773 The redox sensitive transcription factor nuclear factor erythroid 2 related factor 2 (Nrf2) was also induced by acute ethanol in Cyp2e1 ( / ) KI mice but not in Cyp2e1 ( / ) mice. GABPA drug alcohol 22552773 Ethanol induction of CYP2A5 in Nrf2 knockout (Nrf2 ( / )) mice was lower compared with that in WT mice, whereas CYP2E1 induction by ethanol was comparable in WT and Nrf2 ( / ) mice. GABPA drug alcohol 22552773 Antioxidants (N acetyl cysteine and vitamin C), which blocked oxidative stress induced by chronic ethanol in WT mice and acute ethanol in Cyp2e1 ( / ) KI mice, also blunted the induction of CYP2A5 and Nrf2 by ethanol but not the induction of CYP2E1 by ethanol. GABPA drug alcohol 22552773 These results suggest that oxidative stress induced by ethanol via induction of CYP2E1 upregulates Nrf2 activity, which in turn regulates ethanol induction of CYP2A5. GABPA drug alcohol 22552773 Results obtained from primary hepatocytes, mice gavaged with binge ethanol or fed chronic ethanol, show that Nrf2 regulated ethanol induction of CYP2A5 protects against ethanol induced steatosis.

FYN drug alcohol 30536923 We show that systemic administration of AZD0530 prevents alcohol induced Fyn activation and GluN2B phosphorylation in the DMS of mice. FYN drug alcohol 30536923 Together, our findings suggest that AZD0530, through its inhibitory actions on Fyn kinase, dampens alcohol seeking and drinking. FYN addiction relapse 30536923 Together, our findings suggest that AZD0530, through its inhibitory actions on Fyn kinase, dampens alcohol seeking and drinking. FYN drug cocaine 29520592 Thus, by triggering the activation and degranulation of mast cells dependent on the tyrosine kinase c kit and Fyn, the latter being also involved in NMDA dependent synaptic plasticity, cocaine and heroin may indirectly influence the neural mechanisms that mediate their reinforcing properties.

FYN drug cocaine 29520592 Masitinib, a novel tyrosine kinase inhibitor with high selectivity for c Kit, Fyn and Lyn, may alter the aberrant consequences of the activation of these tyrosine kinases by cocaine and heroin. FYN drug opioid 29520592 Masitinib, a novel tyrosine kinase inhibitor with high selectivity for c Kit, Fyn and Lyn, may alter the aberrant consequences of the activation of these tyrosine kinases by cocaine and heroin. FYN drug alcohol 27906494 Specifically, we show that enzymes that participate in the regulation of NMDAR function including Fyn kinase as well as signaling cascades downstream of NMDAR including calcium/calmodulin dependent protein kinase II (CamKII), the α amino 3 hydroxy 5 methyl 4 isoxazolepropionic acid receptor (AMPAR) and the mammalian target of rapamycin complex 1 (mTORC1) play a major role in mechanisms underlying alcohol drinking behaviors. FYN drug alcohol 24588427 Previously, we found that ethanol activates Fyn in the dorsomedial striatum (DMS) leading to GluN2B phosphorylation, which, in turn, underlies the development of ethanol intake (J. FYN drug alcohol 24588427 Here, we tested the hypothesis that inhibition of STEP61 by ethanol is upstream of Fyn/GluN2B. FYN drug alcohol 24588427 Specific knockdown of STEP61 in the DMS of mice enhanced ethanol mediated Fyn activation and GluN2B phosphorylation, and increased ethanol intake without altering the level of water, saccharine, quinine consumption or spontaneous locomotor activity. FYN drug alcohol 24588427 Together, our data suggest that blockade of STEP61 activity in response to ethanol is sufficient for the activation of the Fyn/GluN2B pathway in the DMS. FYN drug alcohol 24588427 Being upstream of Fyn and GluN2B, inactive STEP61 in the DMS primes the induction of ethanol intake. FYN drug alcohol 24588427 We show that ethanol mediated inhibition of STEP61 in the DMS leads to Fyn activation and GluN2B phosphorylation. FYN drug alcohol 24588427 The inhibition of STEP61 activity contributes to the activation of Fyn in response to ethanol, which, in turn, phosphorylates GluN2B. FYN drug alcohol 24005290 We previously found that excessive ethanol drinking activates Fyn in the dorsomedial striatum (DMS) (Wang et al., 2010; Gibb et al., 2011). FYN drug alcohol 24005290 Ethanol mediated Fyn activation in the DMS leads to the phosphorylation of the GluN2B subunit of the NMDA receptor, to the enhancement of the channel's activity, and to the development and/or maintenance of ethanol drinking behaviors (Wang et al., 2007, 2010). FYN drug alcohol 24005290 Protein tyrosine phosphatase α (PTPα) is essential for Fyn kinase activation (Bhandari et al., 1998), and we showed that ethanol mediated Fyn activation is facilitated by the recruitment of PTPα to synaptic membranes, the compartment where Fyn resides (Gibb et al., 2011). FYN drug alcohol 24005290 Here we tested the hypothesis that PTPα in the DMS is part of the Fyn/GluN2B pathway and is thus a major contributor to the neuroadaptations underlying excessive ethanol intake behaviors. FYN drug alcohol 24005290 Furthermore, downregulation of PTPα in the DMS of mice significantly reduces ethanol mediated Fyn activation, GluN2B phosphorylation, and ethanol withdrawal induced long term facilitation of NMDAR activity without altering the intrinsic features of DMS neurons. FYN addiction withdrawal 24005290 Furthermore, downregulation of PTPα in the DMS of mice significantly reduces ethanol mediated Fyn activation, GluN2B phosphorylation, and ethanol withdrawal induced long term facilitation of NMDAR activity without altering the intrinsic features of DMS neurons. FYN drug alcohol 24005290 Together, these results position PTPα upstream of Fyn within the DMS and demonstrate the important contribution of the phosphatase to the maladaptive synaptic changes that lead to excessive ethanol intake. FYN drug alcohol 21985328 The NMDA receptor is a major target of ethanol in the brain, and accumulating evidence suggests that Fyn mediates the effects of ethanol by regulating the phosphorylation of GluN2B NMDA receptor subunits. FYN drug alcohol 21985328 Furthermore, Fyn has been shown to regulate alcohol withdrawal and acute tolerance to ethanol through a GluN2B dependent mechanism. FYN addiction withdrawal 21985328 Furthermore, Fyn has been shown to regulate alcohol withdrawal and acute tolerance to ethanol through a GluN2B dependent mechanism. FYN drug alcohol 21919909 Ethanol induced increase in Fyn kinase activity in the dorsomedial striatum is associated with subcellular redistribution of protein tyrosine phosphatase α. FYN drug alcohol 21919909 In vivo exposure of rodents to ethanol leads to a long lasting increase in Fyn kinase activity in the dorsomedial striatum (DMS). FYN drug alcohol 21919909 In this study, we set out to identify a molecular mechanism that contributes to the enhancement of Fyn activity in response to ethanol in the DMS. FYN drug alcohol 21919909 Protein tyrosine phosphatase α (PTPα) positively regulates the activity of Fyn, and we found that repeated systemic administration or binge drinking of ethanol results in an increase in the synaptic localization of PTPα in the DMS, the same site where Fyn resides. FYN addiction intoxication 21919909 Protein tyrosine phosphatase α (PTPα) positively regulates the activity of Fyn, and we found that repeated systemic administration or binge drinking of ethanol results in an increase in the synaptic localization of PTPα in the DMS, the same site where Fyn resides. FYN drug alcohol 21919909 We also demonstrate that binge drinking of ethanol leads to an increase in Fyn activity and to the co localization of Fyn and PTPα in lipid rafts in the DMS. FYN addiction intoxication 21919909 We also demonstrate that binge drinking of ethanol leads to an increase in Fyn activity and to the co localization of Fyn and PTPα in lipid rafts in the DMS. FYN drug alcohol 21919909 Together, our results suggest that the redistribution of PTPα in the DMS into compartments where Fyn resides is a potential mechanism by which the activity of the kinase is increased upon ethanol exposure. FYN drug amphetamine 21704677 The data clearly suggest that endogenous MK limits amphetamine induced astrocytosis through Fyn , TrkA and ERK1/2 independent mechanisms and identify previously unexpected functional differences between MK and pleiotrophin, the only other member of the MK family of growth factors, in the modulation of effects of drugs of abuse. FYN drug alcohol 20668202 We previously observed that ex vivo acute exposure of the dorsal striatum to, and withdrawal from, alcohol induces long term facilitation (LTF) of the activity of NR2B containing NMDA receptors (NR2B NMDARs) in a mechanism that requires the Src family protein tyrosine kinase (PTK), Fyn (Wang et al., 2007). FYN addiction withdrawal 20668202 We previously observed that ex vivo acute exposure of the dorsal striatum to, and withdrawal from, alcohol induces long term facilitation (LTF) of the activity of NR2B containing NMDA receptors (NR2B NMDARs) in a mechanism that requires the Src family protein tyrosine kinase (PTK), Fyn (Wang et al., 2007). FYN drug alcohol 19119613 Studies in neuropsychopharmacology and molecular neurobiology indicate that neurotransmitters and its receptors play important roles in alcohol abuse and addiction, and post receptor signal transduction pathways, including cyclic adenosine 3', 5' monophosphate (cAMP) protein kinase A (PKA), phosphoinositide (PI), Ca2+ calmodulin (CAM), phospholipase D (PLD) and tyrosine kinase Fyn signaling cascade.

FYN drug cocaine 19046409 Cocaine induced an increase in the activity of both Fyn and Src kinases, and the Src protein tyrosine kinase (Src PTKs) inhibitor, 4 amino 5 (4 chlorophenyl) 7 (t butyl)pyrazolo[3,4 d]pyrimidine (PP2), abolished both cocaine induced increase in tyrosine phosphorylation of the NR2A subunit and the increase in the expression of NR1, NR2A, and NR2B in the VTA.

FYN addiction dependence 18849153 Genetic association between 93A/G polymorphism in the Fyn kinase gene and alcohol dependence in Spanish men. FYN drug alcohol 18849153 Fyn tyrosine kinase is a member of the Scr family that phosphorylates the NR2A and NR2B subunits of the NMDA receptors reducing the inhibitory effects of ethanol and therefore may regulate the individual sensitivity to ethanol. FYN drug alcohol 18849153 To investigate whether there is any relationship between the polymorphism at position 93 of the Fyn kinase gene and the susceptibility to develop alcoholism. FYN drug alcohol 18849153 We studied the distribution of genotypes and alleles of the polymorphism 93A/G (137346 T/C) in the 5' UTR region of the fyn gene in 207 male heavy drinkers (119 with alcohol dependence and 88 with alcohol abuse) and 100 control subjects from Castilla y León (Spain).

FYN drug alcohol 17392475 We found that, in the dorsal striatum, alcohol (ethanol) exposure produced an increase in the phosphorylation of the NR2B subunit of the NMDAR, and a corresponding increase in the activity of Fyn kinase, which phosphorylates NR2B. FYN drug alcohol 17392475 Finally, dorsal but not ventral striatum infusion of a Fyn or NR2B NMDAR inhibitor reduced rat operant self administration of ethanol. FYN addiction reward 17392475 Finally, dorsal but not ventral striatum infusion of a Fyn or NR2B NMDAR inhibitor reduced rat operant self administration of ethanol. FYN drug alcohol 17392475 Our results suggest that the Fyn mediated phosphorylation and LTF of NR2B NMDAR activity in the dorsal striatum after exposure to ethanol may underlie aberrant plasticity that contributes to mechanisms underlying alcohol drinking behavior. FYN drug alcohol 15902902 Fyn kinase does not reduce ethanol inhibition of zinc insensitive NR2A containing N methyl D aspartate receptors. FYN drug alcohol 15902902 Results of studies also support the suggestion that the ethanol inhibition on NR1/2A receptors is reduced by Fyn kinase mediated tyrosine phosphorylation. FYN drug alcohol 15902902 In the current study, the effect of Fyn kinase on the ethanol inhibition of NR1/2A receptors was determined under conditions in which zinc sensitivity is eliminated. FYN drug alcohol 15902902 Under these conditions, Fyn kinase did not reduce ethanol inhibition of wild type receptors. FYN drug alcohol 15902902 Fyn kinase also had no effect on the magnitude of ethanol inhibition of zinc insensitive NR1/2A(H128S) receptors. FYN drug alcohol 15902902 Together, results of the current study indicate that Fyn kinase does not directly affect the ethanol sensitivity of NR1/2A receptors. FYN addiction dependence 14764659 Deletion of the fyn kinase gene alters sensitivity to GABAergic drugs: dependence on beta2/beta3 GABAA receptor subunits. FYN drug alcohol 14675807 Analysis of genetic variations of protein tyrosine kinase fyn and their association with alcohol dependence in two independent cohorts. FYN addiction dependence 14675807 Analysis of genetic variations of protein tyrosine kinase fyn and their association with alcohol dependence in two independent cohorts. FYN drug alcohol 14675807 Decreased sensitivity to and increased tolerance for the effects of alcohol is a phenotype, which was shown to be associated with an increased risk for alcoholism in humans and was observed in protein tyrosine kinase (PTK) fyn knockout mice. FYN drug alcohol 14675807 We performed an association study of genetic variations of PTK fyn in 430 alcohol dependent patients and 365 unrelated control subjects from two independent samples. FYN drug alcohol 14675807 Our results indicate a possible association of alcohol dependence with a genotype of the SNP T137346C of the PTK fyn, with C being the risk allele.

FYN drug alcohol 14634488 Fyn kinase and NR2B containing NMDA receptors regulate acute ethanol sensitivity but not ethanol intake or conditioned reward. FYN addiction reward 14634488 Fyn kinase and NR2B containing NMDA receptors regulate acute ethanol sensitivity but not ethanol intake or conditioned reward. FYN drug alcohol 14634488 The tyrosine kinase Fyn previously has been shown to play a key role in mediating acute tolerance to ethanol. FYN drug alcohol 14634488 Recently, we found that the compartmentalization of Fyn to the NR2B subunit of the NMDA receptor (NMDAR) in the hippocampus regulates Fyn phosphorylation of NR2B in response to ethanol, which mediates the acute tolerance of NMDAR to ethanol inhibition in hippocampal slices. FYN drug alcohol 14634488 In this study we determined, first, whether acute tolerance to ethanol inhibition is mediated via NR2B containing NMDARs in vivo and, second, whether the increase in acute sensitivity to ethanol in the Fyn / mice influences ethanol consumption or ethanol's conditioned rewarding effects. FYN drug alcohol 14634488 We found that systemic injection of the NR2B containing NMDAR selective antagonist, ifenprodil, abolished the differences between Fyn+/+ and Fyn / mice in sensitivity to the acute sedative effects of ethanol. FYN drug alcohol 14634488 Moreover, we found that Fyn / and Fyn+/+ mice did not differ in their voluntary ethanol consumption or in the rewarding properties of ethanol. FYN drug alcohol 14634488 Our results suggest that the interaction between Fyn and NR2B mediates the acute sedative effects of ethanol, and that alteration in acute ethanol sensitivity does not necessarily correlate with levels of ethanol consumption or the rewarding properties of ethanol. FYN drug alcohol 12966312 Role of Fyn tyrosine kinase in ethanol consumption by mice. FYN drug alcohol 12966312 Mice deficient for the intracellular protein Fyn tyrosine kinase (fynZ/fynZ mice) have been reported to show increased alcohol sensitivity and lack of tolerance to the effects of ethanol. FYN drug alcohol 12966312 To further study the involvement of Fyn in neurobehavioral effects of alcohol, we examined ethanol consumption and relapse drinking behavior in fynZ/fynZ mice. FYN addiction relapse 12966312 To further study the involvement of Fyn in neurobehavioral effects of alcohol, we examined ethanol consumption and relapse drinking behavior in fynZ/fynZ mice. FYN drug alcohol 12966312 Deletion of the Fyn tyrosine kinase gene may be involved in ethanol sensitivity but this effect may depend on a gene environment interaction. FYN drug alcohol 12966312 Fyn does not influence ethanol consumption, neither under basal conditions nor following a deprivation period or stress. FYN drug alcohol 12966312 This finding indicates that phosphorylation and activation of N methyl D aspartate (NMDA) receptors through Fyn is not a critical mechanism in alcohol drinking or relapse behavior. FYN addiction relapse 12966312 This finding indicates that phosphorylation and activation of N methyl D aspartate (NMDA) receptors through Fyn is not a critical mechanism in alcohol drinking or relapse behavior. FYN drug alcohol 12878908 Deletion of the fyn kinase gene alters behavioral sensitivity to ethanol. FYN drug alcohol 12878908 An earlier study showed that deletion of the fyn kinase gene enhanced sensitivity to ethanol's sedative hypnotic effects and suggested that this was associated with diminished fyn kinase phosphorylation of NMDA receptors. FYN drug alcohol 12878908 To address the role of fyn kinase in mediating acute tolerance, as well as sensitivity to several other behavioral effects of ethanol, we studied an independently generated population of fyn null mutant and wild type mice. FYN drug alcohol 12878908 Fyn kinase null mutants were more sensitive to the anxiolytic effects of ethanol when tested using the elevated plus maze, and males displayed a lower preference for ethanol in a two bottle choice paradigm. FYN drug alcohol 12878908 These results show that fyn kinase modulates acute tolerance to ethanol and suggest a role for fyn in mediating ethanol's anxiolytic and reinforcing properties. FYN addiction reward 12878908 These results show that fyn kinase modulates acute tolerance to ethanol and suggest a role for fyn in mediating ethanol's anxiolytic and reinforcing properties. FYN drug alcohol 12736333 Scaffolding of Fyn kinase to the NMDA receptor determines brain region sensitivity to ethanol. FYN drug alcohol 12736333 We report here that the brain region specific compartmentalization of Fyn kinase determines NMDA receptor sensitivity to ethanol. FYN drug alcohol 12736333 During acute exposure to ethanol, RACK1 is dissociated from the complex, thereby facilitating Fyn mediated phosphorylation of NR2B, which enhances channel activity, counteracting the inhibitory actions of ethanol. FYN drug cannabinoid 12657697 The endocannabinoid induced stimulation of ERK was lost in Fyn knock out mice, in slices and in vivo, although it was insensitive to inhibitors of Src family tyrosine kinases in vitro, suggesting a noncatalytic role of Fyn. FYN drug alcohol 12399115 Resistance to alcohol withdrawal induced behaviour in Fyn transgenic mice and its reversal by ifenprodil. FYN addiction withdrawal 12399115 Resistance to alcohol withdrawal induced behaviour in Fyn transgenic mice and its reversal by ifenprodil. FYN drug alcohol 12399115 Recent studies suggest that the protein tyrosine kinase Fyn constitutes a determinant of fear and anxiety as well as alcohol sensitivity in mice. FYN drug alcohol 12399115 This apparent lack of alcohol withdrawal induced behavioural effects was associated with increased Fyn activity and tyrosine phosphorylation of several proteins including the NMDA receptor subunit NR2B in the different mutant lines. FYN addiction withdrawal 12399115 This apparent lack of alcohol withdrawal induced behavioural effects was associated with increased Fyn activity and tyrosine phosphorylation of several proteins including the NMDA receptor subunit NR2B in the different mutant lines. FYN drug alcohol 12399115 NR2B phosphorylation itself remained unaffected by the chronic alcohol ingestion and subsequent withdrawal, but challenge with an NR2B antagonist, ifenprodil, restored a normal behavioural response in alcohol withdrawn fyn mutants. FYN addiction withdrawal 12399115 NR2B phosphorylation itself remained unaffected by the chronic alcohol ingestion and subsequent withdrawal, but challenge with an NR2B antagonist, ifenprodil, restored a normal behavioural response in alcohol withdrawn fyn mutants. FYN drug alcohol 12399115 Together, these results suggest that Fyn can modulate alcohol consumption and prevent behavioural changes during alcohol withdrawal, possibly via phosphorylation of NR2B. FYN addiction withdrawal 12399115 Together, these results suggest that Fyn can modulate alcohol consumption and prevent behavioural changes during alcohol withdrawal, possibly via phosphorylation of NR2B.

FGF2 drug alcohol 31375540 We recently found in rodents that alcohol increases fibroblast growth factor 2 (FGF2) expression in the dorsomedial striatum (DMS), which promotes alcohol consumption. FGF2 drug alcohol 31375540 Here, we show that systemic or intra DMS blockade of the FGF2 receptor, FGF receptor 1 (FGFR1), suppresses alcohol consumption, and that the effects of FGF2 FGFR1 on alcohol drinking are mediated via the phosphoinositide 3 kinase (PI3K) signaling pathway. FGF2 drug alcohol 31375540 Finally, inhibition of the PI3K, but not of the mitogen activated protein kinase (MAPK) signaling pathway, blocked the effects of FGF2 on alcohol intake and preference. FGF2 drug alcohol 31375540 Our results suggest that activation of FGFR1 by FGF2 in the DMS leads to activation of the PI3K signaling pathway, which promotes excessive alcohol consumption, and that inhibition of FGFR1 may provide a novel therapeutic target for alcohol use disorder.SIGNIFICANCE STATEMENT Long term alcohol consumption causes neuroadaptations in the mesostriatal reward system, leading to addiction related behaviors.

FGF2 drug alcohol 31375540 Here, we show that long term alcohol intake also increases the expression of the FGF2 receptor, FGFR1 in the DMS. FGF2 drug alcohol 31375540 We further show that the effects of FGF2 FGFR1 on alcohol drinking are mediated via activation of the PI3K intracellular signaling pathway, providing an insight on the mechanism for this effect. FGF2 addiction addiction 30144335 The role of fibroblast growth factor 2 in drug addiction. FGF2 addiction addiction 30144335 Over the past decade, FGF2 has been implicated in learning and memory, as well as in several neuropsychiatric disorders, including anxiety, stress, depression and drug addiction. FGF2 drug alcohol 30144335 In this review, we present accumulating evidence indicating the involvement of FGF2 in neuroadaptations caused by drugs of abuse, namely, amphetamine, cocaine, nicotine and alcohol. FGF2 drug amphetamine 30144335 In this review, we present accumulating evidence indicating the involvement of FGF2 in neuroadaptations caused by drugs of abuse, namely, amphetamine, cocaine, nicotine and alcohol.

FGF2 drug nicotine 30144335 In this review, we present accumulating evidence indicating the involvement of FGF2 in neuroadaptations caused by drugs of abuse, namely, amphetamine, cocaine, nicotine and alcohol. FGF2 drug alcohol 30144335 Moreover, evidence suggests that FGF2 is a positive regulator of alcohol and drug related behaviors. FGF2 drug cocaine 30012881 bFGF expression is differentially regulated by cocaine seeking versus extinction in learning related brain regions. FGF2 addiction relapse 30012881 bFGF expression is differentially regulated by cocaine seeking versus extinction in learning related brain regions. FGF2 addiction relapse 30012881 The persistence of drug associated cues in eliciting drug seeking suggests enduring changes in structural and functional plasticity, which may be mediated by basic fibroblast growth factor (bFGF, FGF2). FGF2 addiction relapse 30012881 The persistence of drug associated cues in eliciting drug seeking suggests enduring changes in structural and functional plasticity, which may be mediated by basic fibroblast growth factor (bFGF, FGF2). FGF2 addiction reward 30012881 Stimulant drug use increases bFGF expression in reward and learning related brain regions, such as the infralimbic medial prefrontal cortex (IL mPFC), and we previously found that this increase was reversed by extinction. FGF2 drug cocaine 30012881 Therefore, we used the conditioned place preference (CPP) paradigm to assess bFGF expression following cocaine associated CPP or extinction of that CPP within the mPFC, nucleus accumbens (NAc), hippocampus (Hipp), and basolateral amygdala (BLA).

FGF2 drug alcohol 28821667 Fibroblast Growth Factor 2 in the Dorsomedial Striatum Is a Novel Positive Regulator of Alcohol Consumption. FGF2 drug alcohol 28821667 Here, we report on a positive regulatory feedback loop of alcohol and FGF2 in rodent models. FGF2 drug alcohol 28821667 Voluntary prolonged and excessive alcohol consumption in a 2 bottle choice procedure increased Fgf2 expression selectively in dorsomedial striatum (DMS) of both mice and rats. FGF2 drug alcohol 28821667 Importantly, we found that systemic administration of recombinant FGF2 (rFGF2) in mice, or rFGF2 infusion into the dorsal striatum or DMS of rats, increased alcohol consumption and preference, with no similar effects on saccharin or sucrose consumption. FGF2 drug alcohol 28821667 Finally, we found that inhibition of the endogenous FGF2 function in the DMS, by an anti FGF2 neutralizing antibody, suppressed alcohol consumption and preference. FGF2 drug alcohol 28821667 Together, our results suggest that alcohol consumption increases the expression of Fgf2 in the DMS, and that striatal FGF2 promotes alcohol consumption, suggesting that FGF2 in the DMS is a positive regulator of alcohol drinking.SIGNIFICANCE STATEMENT Long term alcohol intake may lead to neuroadaptations in the mesostriatal reward system, resulting in addiction phenotypes.

FGF2 drug alcohol 28821667 Here, we provide evidence for the involvement of FGF2 in alcohol drinking behaviors. FGF2 drug alcohol 28821667 We show that alcohol increases Fgf2 expression in the dorsal striatum, an effect mediated via dopamine D2 like receptors. FGF2 drug alcohol 28821667 Importantly, we show that infusion of recombinant FGF2 into the dorsomedial striatum increases alcohol consumption, whereas inhibiting the endogenous FGF2 function suppresses consumption. FGF2 drug alcohol 28821667 Thus, FGF2 is an alcohol responsive gene constituting a positive regulatory feedback loop with alcohol. FGF2 drug alcohol 28821667 This loop leads to facilitation of alcohol consumption, marking FGF2 as a potential new therapeutic target for alcohol addiction.

FGF2 drug cocaine 27129861 Region specific effects of developmental exposure to cocaine on fibroblast growth factor 2 expression in the rat brain. FGF2 drug cocaine 27129861 By microdissection of brain areas via punching, we investigated whether repeated exposure to cocaine during adolescence (from postnatal day 28 [PND28] to PND42) has altered fibroblast growth factor 2 (FGF 2) messenger RNA (mRNA) levels in selected brain subregions critical for the action of cocaine.

FGF2 addiction reward 27129861 Last, we found reduced FGF 2 mRNA levels also in brain regions which, although in a different manner, contribute to the reward system, i.e., the central nucleus of amygdala (cAmy) and the ventral portion of hippocampus (vHip). FGF2 drug cocaine 27129861 The widespread and coordinated reduction of FGF 2 mRNA levels across the brain's reward neurocircuitry might represent a defensive strategy set in motion to oppose to the psychostimulant properties of cocaine. FGF2 addiction reward 27129861 The widespread and coordinated reduction of FGF 2 mRNA levels across the brain's reward neurocircuitry might represent a defensive strategy set in motion to oppose to the psychostimulant properties of cocaine. FGF2 drug cocaine 27129861 Moreover, given the role of FGF 2 in modulating mood disorders, the reduced trophic support here observed might sustain the negative emotional state set in motion by repeated exposure to cocaine. FGF2 drug cocaine 27114539 In contrast, low FGF2 levels, which appear immutable even following prolonged cocaine exposure, may serve as a protective factor. FGF2 drug cocaine 25994078 Blocking Infralimbic Basic Fibroblast Growth Factor (bFGF or FGF2) Facilitates Extinction of Drug Seeking After Cocaine Self Administration.

FGF2 addiction relapse 25994078 Blocking Infralimbic Basic Fibroblast Growth Factor (bFGF or FGF2) Facilitates Extinction of Drug Seeking After Cocaine Self Administration. FGF2 drug cocaine 25994078 Following cocaine exposure, bFGF is increased in addiction related brain regions, including the infralimbic medial prefrontal cortex (IL mPFC). FGF2 addiction addiction 25994078 Following cocaine exposure, bFGF is increased in addiction related brain regions, including the infralimbic medial prefrontal cortex (IL mPFC). FGF2 addiction relapse 25994078 The IL mPFC is necessary for extinction, but whether drug induced overexpression of bFGF in this region affects extinction of drug seeking is unknown. FGF2 drug cocaine 25994078 Thus, we determined whether blocking bFGF in IL mPFC would facilitate extinction following cocaine self administration. FGF2 drug cocaine 25994078 Furthermore, bFGF protein expression increased in IL mPFC following cocaine self administration, an effect reversed by extinction. FGF2 drug cocaine 25994078 These results suggest that cocaine induced overexpression of bFGF inhibits extinction, as blocking bFGF during extinction permits rapid extinction. FGF2 addiction addiction 25994078 Therefore, targeted reductions in bFGF during therapeutic interventions could enhance treatment outcomes for addiction. FGF2 drug cannabinoid 25550231 The purpose of this review is to outline the literature showing how pharmacological interventions targeting neurotransmitter systems including serotonin, dopamine, noradrenaline, histamine, glutamate, GABA, cannabinoids, neuropeptides (oxytocin, neuropeptides Y and S, opioids) and other targets (neurotrophins BDNF and FGF2, glucocorticoids, L type calcium channels, epigenetic modifications) as well as their downstream signaling pathways, can augment fear extinction and strengthen extinction memory persistently in preclinical models. FGF2 drug opioid 25550231 The purpose of this review is to outline the literature showing how pharmacological interventions targeting neurotransmitter systems including serotonin, dopamine, noradrenaline, histamine, glutamate, GABA, cannabinoids, neuropeptides (oxytocin, neuropeptides Y and S, opioids) and other targets (neurotrophins BDNF and FGF2, glucocorticoids, L type calcium channels, epigenetic modifications) as well as their downstream signaling pathways, can augment fear extinction and strengthen extinction memory persistently in preclinical models. FGF2 drug cocaine 25124315 A single exposure to cocaine during development elicits regionally selective changes in basal basic Fibroblast Growth Factor (FGF 2) gene expression and alters the trophic response to a second injection. FGF2 drug cocaine 25124315 Recently, attention has been focused on basic fibroblast growth factor (FGF 2) given that its administration early in life enhances the acquisition of cocaine self administration and sensitization at adulthood (Turner et al.

FGF2 drug cocaine 25124315 Additionally, we found that abstinence from adolescent cocaine exposure long lastingly dysregulates FGF 2 transcription (Giannotti et al. FGF2 drug cocaine 25124315 The objectives of the study are to evaluate if (1) a single injection of cocaine (20 mg/kg) at postnatal day 35 alters FGF 2 messenger RNA (mRNA) levels and (2) the first injection influences the trophic response to a second injection (10 mg/kg) provided 24 h or 7 days later. FGF2 drug cocaine 25124315 We found regional differences in the FGF 2 expression pattern as either the first or the second injection of cocaine by themselves upregulated FGF 2 mRNA in the medial prefrontal cortex and nucleus accumbens while downregulating it in the hippocampus. FGF2 drug cocaine 25124315 Of note, 24 h after the first injection, accumbal and hippocampal FGF 2 changes produced by cocaine in saline pretreated rats were prevented in cocaine pretreated rats. FGF2 drug cocaine 25124315 Conversely, in the medial prefrontal cortex and hippocampus 7 days after the first injection, the cocaine induced FGF 2 changes were modified by the subsequent exposure to the psychostimulant. FGF2 drug cocaine 22895673 Dynamic modulation of basic Fibroblast Growth Factor (FGF 2) expression in the rat brain following repeated exposure to cocaine during adolescence. FGF2 drug cocaine 22895673 Our study stems from four related lines of evidence: (1) FGF 2 is expressed in the developing brain; (2) psychostimulants modulate FGF 2 expression; (3) stress alters FGF 2 expression; and (4) exogenous administration of FGF 2 long lastingly alters cocaine acquisition of self administration. FGF2 drug cocaine 22895673 This research aims to study the effects of adolescent cocaine exposure on FGF 2 mRNA levels and its influence on the response to stress. FGF2 drug cocaine 22895673 In the prefrontal cortex, repeated cocaine treatment during adolescence increased FGF 2 mRNA levels in PND 90 rats and altered its response to an acute stress in both PND 45 and PND 90 rats. FGF2 drug cocaine 22895673 In the hippocampus of PND 45 rats, we found an increase of FGF 2 mRNA levels following repeated cocaine administration. FGF2 drug cocaine 22895673 Our data show that cocaine exposure during adolescence alters FGF 2 mRNA levels throughout life in rat prefrontal cortex and modulates its response to an adverse event. FGF2 drug cocaine 22895673 These results point to FGF 2 as a potential molecular target through which exposure to cocaine early in life may dynamically and persistently alter brain homeostasis. FGF2 addiction relapse 22819969 We previously reported increased levels of basic fibroblast growth factor (FGF2) in high novelty/drug seeking rats (bred high responders, bHR) compared to low novelty/drug seeking rats(bred low responders, bLRs). FGF2 drug cocaine 22819969 The present study asked whether an early life manipulation of the FGF system(a single FGF2 injection on postnatal day 2) can impact cocaine sensitization and associated neurobiological markers in adult bHR/bLR animals. FGF2 addiction sensitization 22819969 The present study asked whether an early life manipulation of the FGF system(a single FGF2 injection on postnatal day 2) can impact cocaine sensitization and associated neurobiological markers in adult bHR/bLR animals. FGF2 drug cocaine 22819969 Neonatal FGF2 and vehicle treated bHR/bLR rats were sensitized to cocaine(7 daily injections, 15 mg/kg/day, i.p.) FGF2 drug cocaine 22819969 Neonatal FGF2 markedly increased bLRs' typically low psychomotor sensitization to cocaine (day 7 locomotor response to cocaine), but had little effect on bHRs' cocaine sensitization. FGF2 addiction sensitization 22819969 Neonatal FGF2 markedly increased bLRs' typically low psychomotor sensitization to cocaine (day 7 locomotor response to cocaine), but had little effect on bHRs' cocaine sensitization. FGF2 drug cocaine 22819969 Gene expression studies examined dopaminergic molecules as well as FGF2 and the FGFR1 receptor in cocaine naïve animals, to investigate possible neurobiological alterations induced by neonatal FGF2 exposure that may influence behavioral response to cocaine. FGF2 drug cocaine 22819969 Neonatal FGF2 selectively increased D1 receptor and FGF2 mRNA in the accumbens core of bLRs, which may contribute to their heightened cocaine sensitization. FGF2 addiction sensitization 22819969 Neonatal FGF2 selectively increased D1 receptor and FGF2 mRNA in the accumbens core of bLRs, which may contribute to their heightened cocaine sensitization. FGF2 drug cocaine 22819969 Our results suggest increased FGF2 in the mesodopaminergic circuit (as in baseline bHRs and neonatal FGF2 exposed bLRs vs. baseline bLRs) enhances an individual's susceptibility to cocaine sensitization and may increase vulnerability to drug seeking and addiction. FGF2 addiction addiction 22819969 Our results suggest increased FGF2 in the mesodopaminergic circuit (as in baseline bHRs and neonatal FGF2 exposed bLRs vs. baseline bLRs) enhances an individual's susceptibility to cocaine sensitization and may increase vulnerability to drug seeking and addiction.

FGF2 drug nicotine 22198237 The anti angiogenic activity of MG624 was mediated via the suppression of nicotine induced FGF2 levels in HMEC Ls. FGF2 drug nicotine 22198237 MG624 decreased nicotine induced early growth response gene 1 (Egr 1) levels in HMEC Ls, and reduced the levels of Egr 1 on the FGF2 promoter. FGF2 addiction dependence 21673064 Dependence on secreted FGF2 for cell growth was tested with FP 1039, an FGFR1 Fc fusion protein. FGF2 drug cocaine 19014962 Neonatal FGF2 alters cocaine self administration in the adult rat. FGF2 addiction relapse 19014962 We report here that rats that were selectively bred for greater drug seeking behavior exhibited higher levels of FGF2 gene expression. FGF2 drug cocaine 19014962 Indeed, early life FGF2 enhanced the acquisition of cocaine self administration in adulthood. FGF2 addiction reward 19014962 However, early life FGF2 did not alter spatial or operant learning in adulthood. FGF2 addiction addiction 19014962 Thus, FGF2 may be an antecedent of vulnerability for drug taking behavior and may provide clues to novel therapeutic approaches for the treatment of addiction. FGF2 drug amphetamine 18513704 Amphetamine induced rotations performed 3, 6 and 9 weeks postgrafting revealed that grafts of FGF2 expanded cells induced a significantly faster and better functional recovery than grafts of FGF8 expanded cells or control cells (P<0.05 for both). FGF2 drug cocaine 17914648 Stress and cocaine interact to modulate basic fibroblast growth factor (FGF 2) expression in rat brain. FGF2 drug cocaine 17914648 Our laboratory has previously demonstrated that the expression of basic fibroblast growth factor (FGF 2), a protein involved in survival and maintenance of several cell phenotypes as well as in synaptic plasticity, is modulated by stress (Molteni et al., Brain Res Rev 37:249 258, 2001; Fumagalli et al., Neurobiol Dis 20:731 737, 2005) and cocaine (Fumagalli et al., J Neurochem 96:996 1004, 2006). FGF2 drug cocaine 17914648 Since it is widely recognized that stress influences drug seeking, we decided to investigate whether stress, acute or repeated, could influence the changes in FGF 2 gene expression brought about by cocaine. FGF2 addiction relapse 17914648 Since it is widely recognized that stress influences drug seeking, we decided to investigate whether stress, acute or repeated, could influence the changes in FGF 2 gene expression brought about by cocaine. FGF2 drug cocaine 17914648 Our data demonstrate that stress and cocaine interact to produce significant changes on FGF 2 expression in rat prefrontal cortex and striatum. FGF2 drug cocaine 17914648 In prefrontal cortex, our experiments demonstrated that a single exposure to stress potentiated cocaine induced FGF 2 elevation, whereas prolonged stress prevented the modulation of the trophic factor in response to cocaine. FGF2 drug cocaine 17914648 In striatum, the magnitude of cocaine induced FGF 2 response is enhanced by repeated stress, whereas no interaction was observed when acute stress and single exposure to cocaine were combined. FGF2 drug cocaine 17914648 Our findings demonstrate that stress interacts with cocaine to alter the pattern of FGF 2 expression in a way that depends on whether stress is acute or chronic and in a regionally selective fashion. FGF2 addiction withdrawal 17406596 Hepatic differentiation and maturation of cells is accomplished by withdrawal of Activin A and FGF 2 and by exposure to liver nonparenchymal cell derived growth factors, a deleted variant of hepatocyte growth factor (dHGF) and dexamethasone. FGF2 drug amphetamine 16487142 In vivo studies suggest that AMPH sensitization requires enhanced expression of basic fibroblast growth factor (bFGF) in the nucleus of midbrain astrocytes. FGF2 addiction sensitization 16487142 In vivo studies suggest that AMPH sensitization requires enhanced expression of basic fibroblast growth factor (bFGF) in the nucleus of midbrain astrocytes. FGF2 drug amphetamine 16487142 One idea is that the AMPH induced increase in bFGF expression in astrocytes leads to enhanced secretion of this peptide and to long term plasticity in DA neurons. FGF2 drug amphetamine 16487142 Together these data demonstrate that under basal conditions (in the absence of a pharmacological stimulus such as amphetamine) bFGF is not secreted even though there is abundant nuclear expression in astrocytes. FGF2 drug alcohol 12676135 We have expanded neuroepithelial cells dissociated from the embryonic rat telencephalon in serum free defined medium containing basic fibroblast growth factor (bFGF) in order to generate a model neuroepithelium to study the interaction of ethanol with both growth factor and transmitter stimulated proliferation. FGF2 drug alcohol 12676135 Ethanol blocked proliferation stimulated by bFGF and by carbachol, an agonist at muscarinic acetylcholine receptors, in a dose dependent manner. FGF2 drug alcohol 12676135 In addition, ethanol attenuated autonomous expansion of neuroepithelial cells occurring following withdrawal of bFGF. FGF2 addiction withdrawal 12676135 In addition, ethanol attenuated autonomous expansion of neuroepithelial cells occurring following withdrawal of bFGF. FGF2 addiction sensitization 10972461 Possible mechanisms whereby bFGF participates in the development of sensitization, including interactions with other neurotrophic factors, are discussed. FGF2 drug amphetamine 10632621 We reported previously that repeated amphetamine treatment results in increased astrocytic expression of basic fibroblast growth factor (bFGF) in the ventral tegmental area (VTA) and substantia nigra compacta (SNc) and that this effect is prevented by coadministration of a nonspecific glutamate receptor antagonist. FGF2 drug amphetamine 10632621 Here we show that the development of sensitization to amphetamine is prevented when amphetamine injections are preceded by infusions of a neutralizing antibody to bFGF into the VTA. FGF2 addiction sensitization 10632621 Here we show that the development of sensitization to amphetamine is prevented when amphetamine injections are preceded by infusions of a neutralizing antibody to bFGF into the VTA. FGF2 addiction sensitization 10632621 In addition, we show that astrocytic bFGF expression is increased in the VTA and SNc of animals that exhibit behavioral sensitization and that the number of bFGF immunoreactive astrocytes in these regions is strongly and positively correlated with the magnitude of sensitization. FGF2 addiction sensitization 10632621 Cotreatment with an NMDA glutamate receptor antagonist blocks both the development of behavioral sensitization and bFGF induction. FGF2 drug amphetamine 10632621 These results show that endogenous bFGF is necessary for the development of sensitization to amphetamine and suggest that bFGF mediates the glutamatergic dopaminergic interaction that initiates the long term consequences of repeated drug use. FGF2 addiction sensitization 10632621 These results show that endogenous bFGF is necessary for the development of sensitization to amphetamine and suggest that bFGF mediates the glutamatergic dopaminergic interaction that initiates the long term consequences of repeated drug use. FGF2 drug amphetamine 9801391 Because glutamate participates in the development of sensitization to stimulant drugs, we assessed the effect of the glutamate antagonist, kynurenic acid (KYN), on amphetamine induced bFGF IR. FGF2 addiction sensitization 9801391 Because glutamate participates in the development of sensitization to stimulant drugs, we assessed the effect of the glutamate antagonist, kynurenic acid (KYN), on amphetamine induced bFGF IR. FGF2 drug amphetamine 9801391 Coadministration of KYN prevented the increases in bFGF IR in both VTA and SNc assessed 1 week after the amphetamine treatment. DLG4 addiction withdrawal 32450347 At hippocampal level, the withdrawal induced changes in the levels of AMPA receptor GluA1 and GluA2/3 subunits, PSD 95 protein, corticotropin releasing factor (Crf) and Crf receptor 1 (CrfR1) mRNA were biphasic: AMPA receptor subunit and PSD95 protein levels initially remained unchanged and decreased after 60 90 days, whereas Crf/CrfR1 mRNA levels initially increased and then markedly decreased after 60 days. DLG4 drug opioid 31735530 Methylation in Syn and Psd95 genes underlie the inhibitory effect of oxytocin on oxycodone induced conditioned place preference. DLG4 addiction reward 31735530 via its receptor specifically blocked Oxy CPP, normalized synaptic density, and regulated DNMT1 and TET2 3 causing reverse of DNA demethylation of Syn and Psd95. DLG4 drug opioid 31454827 D methadone administration also increased levels of the synaptic proteins, PSD95, GluA1, and Synapsin 1 and enhanced synaptic function in the mPFC. DLG4 addiction withdrawal 30733663 We then analyzed the expression levels of presynaptic (vGlut1, vGlut2, CB1 receptor, synaptophysin) and postsynaptic (PSD95, GluN1, GluN2A, GluN2B, GluA1, GluA2, mGluR1 and mGluR5) proteins after 7 days EtOH incubation or after EtOH withdrawal. DLG4 drug cannabinoid 30623520 We analyzed PSD95 and gephyrin protein levels, gene expression of glutamatergic, GABAergic and endocannabinoid elements, and amino acid transmitter levels. DLG4 drug cocaine 30144237 In cocaine naïve animals, SERT removal led to reduced baseline Hb mRNA levels of critical determinants of glutamate transmission, such as SLC1A2, the main glutamate transporter and N methyl D aspartate (Grin1, Grin2A and Grin2B) as well as α amino 3 hydroxy 5 methyl 4 isoxazolepropionic acid (Gria1 and Gria2) receptor subunits, with no changes in the scaffolding protein Dlg4. DLG4 drug amphetamine 29441405 In rats that reinstated methamphetamine seeking, these altered electrophysiological properties of GCNs were associated with enhanced expression of Fos, GluN2A subunits and PSD95 and reduced expression of GABAA subunits in the DG and enhanced expression of synaptic PSD in the molecular layer. DLG4 addiction relapse 29441405 In rats that reinstated methamphetamine seeking, these altered electrophysiological properties of GCNs were associated with enhanced expression of Fos, GluN2A subunits and PSD95 and reduced expression of GABAA subunits in the DG and enhanced expression of synaptic PSD in the molecular layer. DLG4 addiction addiction 29234834 One day after the final self administration session, the rats were euthanized and the dmPFC was removed for quantification of mRNA expression of critical glutamatergic signaling genes, Homer2, Grin1, and Dlg4, as these genes and brain region have been previously implicated in addiction, learning, and memory. DLG4 drug cocaine 29234834 Lastly, Homer2, Grin1, and Dlg4 mRNA were impacted by both duration and mode of cocaine exposure.

DLG4 addiction dependence 26442368 To observe the expression of discs large homolog 4 (DLG4) protein in hippocampus, amygdala and frontal cortex of rats and evaluate postsynaptic density in heroin dependence. DLG4 drug opioid 26442368 DLG4 proteins in hippocampus, amygdala and frontal cortex of heroin dependent 9, 18, 36 days rats were detected with immunohistochemical staining and compared with that in the control group. DLG4 drug opioid 26442368 DLG4 proteins in hippocampus, amygdala and frontal cortex were gradually reduced with extension of heroin dependent time. DLG4 drug alcohol 25755642 Western blot analysis of tissue samples from the NAc enriched for PSD proteins revealed a main effect of ethanol treatment on the expression of GluN2B, but there was no effect of genotype or treatment on the expression other glutamate receptor subunits or PSD95. DLG4 drug opioid 24704371 An upregulation of expression of phosphorylated cAMP response element binding protein (pCREB) and the occupancy of pCREB in the Dlg4 promoter region were shown in the VTA of the morphine conditioned rats. DLG4 drug opioid 24704371 Inhibition of pCREB activity significantly decreased the histone H3 acetylation in Dlg4 promoter region, PSD 95 upregulation, enhancement of glutamatergic strength and the preference to morphine paired chamber in the rats with morphine conditioning. DLG4 drug cocaine 20600170 In the ventral tegmental area, cocaine self administration elevated glutamatergic receptor subunits NR1 and GluR1 and scaffolding protein PSD95, but not GABA(A)β, protein levels. DLG4 drug cannabinoid 19384563 A significant decrease in synaptophysin and PSD95 proteins was found in the prefrontal cortex of THC pre treated rats, with no alterations in the hippocampus.

CYP1A2 drug nicotine 32376004 Tobacco is well identified for its effects as an inducer of CYP1A2 enzyme. CYP1A2 drug nicotine 32376004 In a COVID+ patient, the consequences of an abrupt cessation of smoking, particularly related with the appearance of respiratory symptoms (cough, dyspnea), must therefore be anticipated for patients receiving psychotropics metabolized by CYP1A2. CYP1A2 drug nicotine 29871580 CYP1A2 is induced by cigarette smoking, which may change the plasma level of clozapine, especially if consuming habits change. CYP1A2 drug opioid 29333880 Variants in six pharmacokinetic genes (CYP1A2, CYP2B6, CYP2C19, CYP2C9, CYP2D6, CYP3A4) and five pharmacodynamic genes (HTR2A, OPRM1, ADRA2A, COMT, SLC6A4) were genotyped in samples from a 24 week, randomized, open label trial of methadone and buprenorphine/naloxone for the treatment of opioid dependence (n = 764; 68.7% male). CYP1A2 addiction dependence 29333880 Variants in six pharmacokinetic genes (CYP1A2, CYP2B6, CYP2C19, CYP2C9, CYP2D6, CYP3A4) and five pharmacodynamic genes (HTR2A, OPRM1, ADRA2A, COMT, SLC6A4) were genotyped in samples from a 24 week, randomized, open label trial of methadone and buprenorphine/naloxone for the treatment of opioid dependence (n = 764; 68.7% male). CYP1A2 drug nicotine 27106177 On the basis of the estimated half life of CYP1A2, dose reduction of CYP1A drugs may be necessary as early as the first few days after smoking cessation to prevent toxicity, especially for drugs with a narrow therapeutic index. CYP1A2 addiction dependence 27067104 Emphasis was placed on 3 hydroxymethylantipyrine (3HMAP), the metabolite with the greatest dependence on dioxin inducible cytochrome P4501A2 (CYP1A2) activity. CYP1A2 drug nicotine 27067104 Multiple regression models were constructed using the three major AP metabolites as a dependent variable to assess the influence of age, smoking as urinary cotinine concentration, dioxin exposure (as either WHO TEQ or body burden), group, and CYP1A2*F ( 163C>A) genotypes. CYP1A2 addiction addiction 26626327 Although depressive or obsessive compulsive symptoms may improve, a SSRI with no CYP1A2 inhibition should rather be used (C). CYP1A2 drug nicotine 25052559 Several statistically significant interactions were observed between smoking and genetic variants (CYP1A2 1548C>T, CYP1A1 3801T>C, CYP1B1 4326G>C, NAT1 c. 85 1014T>A, UGT1A7 W208R 622T>C, SOD2 c.47T>C, GSTT1 deletion). CYP1A2 drug nicotine 24170642 Smoking is very common among psychiatric patients and can induce CYP1A2 enzymes, thereby lowering expected plasma levels of certain SGAs. CYP1A2 drug opioid 19133059 Contribution of the activities of CYP3A, CYP2D6, CYP1A2 and other potential covariates to the disposition of methadone in patients undergoing methadone maintenance treatment. CYP1A2 drug benzodiazepine 19133059 CYP2D6 activity [3 h plasma metabolic ratio of dextromethorphan (DEX) to dextrorphan (DOR)] was determined in 44 patients (29 male; 24 55 years), CYP1A2 activity (salivary caffeine elimination half life) in 44 patients (21 male; 24 55 years) and CYP3A activity (oral clearance of midazolam) in 49 patients (33 male; 23 55 years). CYP1A2 drug opioid 19133059 Neither CYP2D6 nor CYP1A2 activity was related to methadone disposition. CYP1A2 drug opioid 15501692 CYP2D6 and probably CYP1A2 are also involved in methadone metabolism. CYP1A2 drug nicotine 12618594 The effect of smoking and cytochrome P450 CYP1A2 genetic polymorphism on clozapine clearance and dose requirement. CYP1A2 drug nicotine 12618594 Smoking is a potent inducer of CYP1A2 enzyme activity, resulting in significant lower clozapine serum concentrations in smokers compared with non smokers, upon a given dose. CYP1A2 drug nicotine 12618594 Because this polymorphism in relation to smoking behaviour may be relevant in treatment with clozapine, we studied the effect of CYP1A2 genotype on clozapine clearance and dose requirement in a group of 80 smoking and non smoking schizophrenic patients on long term clozapine therapy. CYP1A2 drug nicotine 12618594 Neither among smokers, nor among non smokers mean C/D ratios and daily doses did vary significantly between patients with the different CYP1A2 genotypes. CYP1A2 drug nicotine 12618594 The results show that clozapine clearance and daily dose requirement are strongly associated with smoking behaviour, while the CYP1A2 genetic polymorphism seems to have no significant clinical effect. CYP1A2 drug nicotine 12189363 CYP1A2 activity was measured in 2 women highly exposed to 2,3,7,8 tetrachlorodibenzo p dioxin (TCDD), in 1 man moderately exposed, and in 50 control subjects (30 nonsmokers and 20 heavy smokers). CYP1A2 drug nicotine 11981356 Plasma levels of clozapine and olanzapine are lower in smokers than in nonsmokers, which is mainly due to induction of cytochrome P4501A2 (CYP1A2) by some smoke constituents. CYP1A2 drug nicotine 11981356 Smoking cessation in patients treated with antipsychotic drugs that are CYP1A2 substrates may result in increased plasma levels of the drug and, consequently, in adverse drug effects. CYP1A2 drug nicotine 11981356 The clinical implication of these observations is that smoking patients treated with CYP1A2 substrate antipsychotics should regularly be monitored with regard to their smoking consumption in order to adjust doses in cases of a reduction or increase in smoking. CYP1A2 drug alcohol 9390106 Impact of long term ethanol consumption on CYP1A2 activity. CYP1A2 drug alcohol 9390106 The aim of our study was to evaluate the impact of ethanol consumption on the activity of CYP1A2, which has been shown to be influenced by drugs (inhibited or induced). CYP1A2 drug alcohol 9390106 Our results confirm the well known induction of CYP1A2 activity by tobacco smoking and show that this induction is masked by long term ethanol consumption.

CPM drug opioid 31719641 CPM identified an opioid abstinence network (p = 0.018), characterized by stronger within network motor/sensory connectivity, and reduced connectivity between the motor/sensory network and medial frontal, default mode, and frontoparietal networks. CPM drug cocaine 30606049 The authors sought to identify a brain based predictor of cocaine abstinence by using connectome based predictive modeling (CPM), a recently developed machine learning approach. CPM drug cocaine 30606049 CPM with leave one out cross validation was conducted to identify pretreatment networks that predicted abstinence (percent cocaine negative urine samples during treatment). CPM drug opioid 29288475 Nurses' knowledge was better in regard of CPM guidelines, while they had poor knowledge about pharmacological pain management and opioid addiction. CPM addiction addiction 29288475 Nurses' knowledge was better in regard of CPM guidelines, while they had poor knowledge about pharmacological pain management and opioid addiction. CPM drug opioid 29288475 Physicians and nurses perceived knowledge deficit, lack of pain assessment, opioid unavailability, and lack of psychological interventions as the most common barriers to CPM. CPM addiction withdrawal 29047208 At approximately day 10 following the 3rd injection, CPM treated rats exhibited colorectal hyperalgesia as they showed significantly greater abdominal withdrawal responses (AWR) to graded colorectal distension (CRD, 0 100 mm Hg) than the saline group. CPM drug opioid 29047208 Immunofluorescent staining and Western blot assay revealed that CPM induced colorectal hyperalgesia was associated with significantly increased expression of aromatase and phosphorylated μ type opioid receptor (pMOR) and decreased expression of total MOR in the RVM. CPM drug opioid 28944405 Nurses appeared knowledgeable about CPM guidelines but were unfamiliar regarding pharmacological management and had negative attitudes toward opioids addiction and pain assessment. CPM addiction addiction 28944405 Nurses appeared knowledgeable about CPM guidelines but were unfamiliar regarding pharmacological management and had negative attitudes toward opioids addiction and pain assessment. CPM drug opioid 28722815 There were no significant effects of naloxone nor nocebo on PPT, deep tissue pain, temporal summation or CPM in the control group. CPM drug opioid 28722815 Besides, neither morphine nor naloxone influenced deep tissue pain, temporal summation or CPM. CPM drug opioid 28722815 Therefore, these results suggest that the opioid system is not dominant in (enhanced) bottom up sensitization (temporal summation) or (impaired) endogenous pain inhibition (CPM) in patients with CFS/FM or RA.

CPM drug alcohol 28289647 Generally, the cause and pathogenesis of CPM in chronic alcoholics remain unclear. CPM drug alcohol 27610136 Central pontine myelinolysis (CPM), a potentially fatal and debilitating neurological condition, was first described in 1959 in a study on alcoholic and malnourished patients. CPM drug alcohol 27610136 Chronic alcoholism associated CPM tends to be benign with a favorable prognosis compared to CPM secondary to rapid correction of hyponatremia. CPM drug alcohol 27610136 We describe a normonatremic, alcoholic patient who presented with CPM after a rapid rise in his sodium levels. CPM drug alcohol 27610136 Furthermore, clinical evolution of CPM can be difficult to discern from the natural course of alcohol withdrawal delirium, requiring astuteness and maintenance of a high degree of clinical suspicion on the part of the physician.

CPM drug opioid 24640176 Identification of barriers to opioid use by the physicians and policy makers/regulators, and their level of knowledge and attitudes concerning its use are influential factors for cancer pain management (CPM). CPM drug opioid 24640176 This study was performed to assess the knowledge and attitudes physicians and policy makers/regulators have regarding use of opioids for CPM. CPM drug opioid 24640176 The strengthening of ongoing educational programs regarding opioid use for CPM, and cooperation among key groups are needed. CPM drug nicotine 24162926 Study 1 results revealed that 90% of videos illustrated a four step CPM technique: 'Loosening the tobacco'; 'Dumping the tobacco'; 'Removing the cigar binder' and 'Repacking the tobacco'. CPM drug nicotine 24162926 These findings highlight a novel means for youth to access information concerning CPM that may have important implications for tobacco control policy and prevention.

CPM drug alcohol 19940203 Central pontine myelinolysis (CPM) has been described in alcoholic patients and in the aftermath of rapid correction of chronic hyponatraemia. CPM drug alcohol 19940203 This is the first reported case of nephrogenic DI resulting in the development of CPM, despite a relatively slow rise in plasma sodium of less than 12 mmol/L/24 h. Coexisting alcohol abuse, hypoxaemia and hypokalaemia may have contributed significantly to the development of CPM in this patient. CPM drug alcohol 18678596 Central pontine myelinolysis (CPM) and extrapontine myelinolysis (EPM) are well recognized syndromes that are related to various conditions such as rapid correction of hyponatremia and chronic alcoholism.

CPM addiction relapse 16173886 This was largely a result of changes in self reported craving and was interpreted as consistent with the CPM. CPM drug opioid 15827729 The effectiveness of cancer pain management (CPM) is influenced by nurses' willingness to maximize opioid analgesia for severe cancer pain. CPM drug opioid 15827729 The purposes of this study were to identify the willingness of nurses to provide maximum dose opioids whenever needed for CPM and to determine its associated predictors. CPM drug opioid 15827729 The respondents who were more likely to recommend morphine showed the following characteristics: older nurses (odds ratio, OR, 1.57; confidence interval, CI, 1.13 2.19); they knew the effectiveness of opioids for CPM (OR 1.53; CI 1.06 2.20); rarely concerned about a patient's addiction to opioids (OR 2.16; CI 1.48 3.15), or to a family member's addiction (OR 1.81; CI 1.20 2.73); prior experience with pain assessment tools (OR 1.62; CI 1.11 2.37); practical experience caring for cancer patients with pain over 51% (OR 1.55; CI 1.09 2.19).

IFI30 drug opioid 17142651 Magnesium sulphate (100 mg x kg( 1)) was injected ip 30 min prior to the first sc fentanyl injection. IFI30 drug amphetamine 15985714 Moreover, AMPH injected 8 days after the last dose of repeated AMPH administration did not change NPY LI up to 72 h. The minimal dose of haloperidol, the strong mixed dopaminergic D2/D1 receptor antagonist, (0.75 mg/kg injected ip 30 min before each of the multiple AMPH administrations) that was sufficient to completely block stereotypy and hyperlocomotion elicited by multiple AMPH administrations enhanced the AMPH induced decrease in the striatal and accumbens NPY LI. IFI30 drug cannabinoid 11498713 Another group of rats was initially trained to discriminate between 3 mg/kg Delta9 THC and vehicle given IP 30 min prior to session onset; for anandamide testing, the animals were retrained with 1.8 and 5.6 mg/kg Delta9 THC.

FKBP5 drug cocaine 31029877 Chronic cocaine administration upregulates FKBP5 in the extended amygdala of male and female rats. FKBP5 drug cocaine 31029877 While FKBP5 is known to be involved in mood and stress related disorders, less is known regarding FKBP5 and cocaine abuse. FKBP5 drug cocaine 31029877 This study investigated the regulation of FKBP5 expression in the extended amygdala and paraventricular nucleus of the hypothalamus, regions important in the control of stress responses and HPA axis function, following chronic and acute cocaine administration. FKBP5 drug cocaine 31029877 FKBP5 mRNA levels were significantly elevated as a result of chronic cocaine administration in both males and females in the PVN and BNST 30 min and 24 h after the final injection.

FKBP5 addiction reward 27709495 In rats, Fkbp5 expression in the nucleus accumbens and ventral tegmental area, core regions of the reward system, was affected in a region dependent manner and in opposite direction by maternal separation and alcohol drinking. FKBP5 drug alcohol 27709495 Fkbp5 expression in the cingulate cortex was affected by the combined effect of maternal separation and alcohol drinking. FKBP5 drug alcohol 27709495 The present findings suggest that Fkbp5 expression in mesocorticolimbic dopaminergic regions associates with early life stress mediated sensitivity to alcohol drinking and that FKBP5 genotype interacts with parent child relationship to influence alcohol drinking. FKBP5 drug alcohol 27709495 These findings are the first to point to a role of FKBP5 in propensity to alcohol misuse and call for studies of the underlying molecular mechanisms to identify potential drug targets.

CCL5 addiction withdrawal 21802933 Sputum was also analysed for mRNA levels of haemoxygenase 1, tumour necrosis factor α, RANTES, interleukin 5(IL 5), IL 10, IL 12, IL 13, transforming growth factor β, and interferon γ. Cox regression analyses were performed using time to exacerbation as outcome variable to identify significant hazards for a COPD exacerbation after ICS withdrawal. CCL5 drug opioid 18815890 CCL5/RANTES gene deletion attenuates opioid induced increases in glial CCL2/MCP 1 immunoreactivity and activation in HIV 1 Tat exposed mice. CCL5 drug opioid 18815890 CCL5/RANTES gene deletion attenuates opioid induced increases in glial CCL2/MCP 1 immunoreactivity and activation in HIV 1 Tat exposed mice. CCL5 drug opioid 18815890 To assess the role of CC chemokine ligand 5 (CCL5)/RANTES in opiate drug abuse and human immunodeficiency virus type 1 (HIV 1) comorbidity, the effects of systemic morphine and intrastriatal HIV 1 Tat on macrophage/microglial and astroglial activation were assessed in wild type and CCL5 knockout mice. CCL5 drug opioid 18815890 To assess the role of CC chemokine ligand 5 (CCL5)/RANTES in opiate drug abuse and human immunodeficiency virus type 1 (HIV 1) comorbidity, the effects of systemic morphine and intrastriatal HIV 1 Tat on macrophage/microglial and astroglial activation were assessed in wild type and CCL5 knockout mice. CCL5 drug opioid 18815890 Glial activation was significantly reduced in CCL5( / ) compared to wild type mice at 7 days following combined Tat and morphine exposure. CCL5 drug opioid 18815890 Moreover, the percentage of 3 nitrotyrosine immunopositive macrophages/microglia was markedly reduced in CCL5( / ) mice injected with Tat +/ morphine compared to wild type counterparts, suggesting that CCL5 contributes to nitrosative stress in HIV 1 encephalitis. CCL5 drug opioid 18815890 In CCL5( / ) mice, the reductions in Tat +/ morphine induced gliosis coincided with significant declines in the proportion of CCL2/MCP 1 immunoreactive astrocytes and macrophages/microglia compared to wild type counterparts. CCL5 drug opioid 18815890 Macrophages/microglia differed showing modest, albeit significant, increases in the proportion of CCL2 positive cells with combined Tat and morphine exposure, suggesting that CCL5 preferentially affects CCL2 expression by astroglia. CCL5 drug opioid 18815890 Thus, CCL5 mediates glial activation caused by Tat and morphine, thereby aggravating HIV 1 neuropathogenesis in opiate abusers and non abusers. CCL5 drug alcohol 12062632 This model correlates closely with alcoholic hepatitis in human beings, characterized by increased IL 8, RANTES (regulated upon activation, normal T cell expressed and secreted), and macrophage inflammatory protein 1 (MIP 1) and profound increases in neutrophils and lymphocytes in the liver. CCL5 drug alcohol 12045006 Serum ALT, endotoxin, MIP 1alpha, MCP 1 and RANTES, (but not CINC and MIP 2) were also increased in the ethanol fed rats than in the pair fed group. CCL5 drug alcohol 12045006 Isolated Kupffer cells from ethanol fed rats were primed for enhanced MIP 1alpha, MCP 1, and RANTES production in vitro, while the endothelial cells were primed for enhanced MIP 1alpha release only. CCL5 drug alcohol 12044837 Acute ethanol administration downregulates human immunodeficiency virus 1 glycoprotein 120 induced KC and RANTES production by murine Kupffer cells and splenocytes. CCL5 drug alcohol 12044837 Oral administration of ethanol significantly suppressed HIV 1gp120 induced KC and RANTES release. CCL5 drug alcohol 11388697 However, ethanol alone primed isolated Kupffer cells for enhanced RANTES mRNA and protein release in the presence or absence of HIV 1 gp120.

CCL5 drug opioid 10708810 In this study, chemotaxis of monkey leukocytes was evaluated using the chemokines interleukin 8 (IL 8) and regulated upon activation, normal T cell expressed (RANTES) as the chemoattractants, and the effects of various opioid agonists and antagonists on the efficiency of chemotaxis were examined. CCL5 drug opioid 10708810 Opioids were either incubated with monkey leukocytes or added directly to chemokines, and the number of cells migrating toward IL 8 (for neutrophils) or RANTES (for monocytes) was scored. CCL5 drug opioid 10654191 In this study, chemotaxis of monkey leukocytes was evaluated using human chemokines IL 8 (interleukin 8), MIP 1 beta and RANTES as the chemoattractants, and the effects of micro opioid receptor agonists, morphine, DAMGO, methadone and endomorphine, on the efficiency of chemotaxis were examined. CCL5 drug cocaine 7732307 Deaths by acute reaction from drugs consumption (RAD) particularly heroine or cocaine, collected in routine morality statistics, have not changed substantially during the last ten years, whereas an specific collection system (State Information System on Drug Abuse SISD) presented a great increase. APOA1 addiction dependence 24376512 The present study identified a multiplier effect from a polymorphism in CETP with ABCA1, APOA1, and SR B1, as well as a dose dependence according to the number of alleles present.

APOA1 drug opioid 21453194 The aim was to evaluate the frequency in serum lipid disturbances of hepatitis C virus (HCV) seronegative heroin addicts; the capacity of high density lipoprotein (HDL) C and apolipoprotein B (apoB)/apolipoprotein A I (apoA I) for predicting hypertriglyceridemia/low HDL C profile; correlation of HDL C with the apoB/apoA I and their correlation to plasma apo/lipoproteins. APOA1 drug opioid 21453194 ApoB/apoA I showed stronger correlation with the observed apo/lipoproteins than the HDL C. The logistic regression model showed that apoB/apoA I index (OR 89.1, 95% CI 1.3 5971.2) is more significant predictor in developing hypertriglyceridemia/low HDL profile than HDL C. Heroin addiction is associated with decreased plasma concentrations of HDL C, apoA I, apoB, and increased TGL concentrations.

APOA1 drug opioid 21453194 In heroin addicts, HDL C concentrations are significantly associated with the apoB/apoA I index, which correlates to all lipid fractions and is a stronger predictor of metabolic syndrome lipid profile in heroin addicts. APOA1 drug alcohol 16739925 Ethanol inhibited LCAT and LPL activities, and increased apoA containing LP in blood serum. APOA1 drug nicotine 16372134 Plasma APOB and LDL C, but not APOA1 and HDL C, were shown to be markedly elevated in smokers versus non smokers, affirming that smoking may selectively impact the former pathway. APOA1 drug alcohol 12916168 The 14th day after alcohol abolition was characterized by tendency to normalization of these disturbances, but at the 30th day of soberness a recurrence growing the changes of apoA containing lipoproteins transformation was observed.

APOA1 addiction sensitization 12486210 It is concluded that troglitazone doses known to achieve insulin sensitization did not enhance rat apoA I promoter activity sufficiently to result in an increased apoA I mRNA or protein expression in the intact rat. APOA1 drug alcohol 11981126 ApoE genotypes and concentrations of serum cholesterol, triglyceride, and Lps containing apoA I, A II, B, E, and C III were determined in 84 male alcohol abusers before and after 3 weeks of abstinence. APOA1 addiction withdrawal 11981126 After withdrawal, concentrations of serum apoA I, LpA I, LpA I/A II, apoC III, LpC III non B, apoE, and LpE non B significantly decreased, whereas those of triglycerides and apoB increased; levels of cholesterol, LpC III:B, and LpB:E were not affected. APOA1 drug alcohol 8855152 Serum concentrations of apo A I, LpA I, LpA I:A II, apo C III, and LpC III significantly (P alcohol intake (mean +/ SE in low drinkers vs in alcoholics) 1.45 +/ 0.03 vs 1.78 +/ 0.05 g/L; 0.45 +/ 0.02 vs 0.56 +/ 0.02 g/L; 0.99 +/ 0.02 vs 1.22 +/ 0.04 g/L; 27.6 +/ 1.5 vs 39.7 +/ 1.7 mg/L; and 8.4 +/ 0.9 vs 24.7 +/ 1.7 mg/L, respectively whereas apo B and LpC III:B concentrations tended to decrease 1.20 +/ 0.04 vs 1.06 +/ 0.04 g/L and 19.3 +/ 1.2 vs 14.9 +/ 1.0 mg/L, respectively. APOA1 addiction withdrawal 8855152 After withdrawal, the concentrations of serum apo A I, apo C III, LpA I, LpA I:A II, and LpC III decreased significantly (P alcohol consumption remained positively correlated to apo A I, LpA I:A II, apo C III, and LpC III concentrations. APOA1 drug alcohol 8855152 Study of other determinants of serum apo and lipoprotein concentrations suggests that alcohol related variations in some of them, especially apo A I, might depend on the metabolic ability of the liver to synthesize proteins and on induction phenomena. APOA1 drug alcohol 8003113 Apo A I levels decreased ( 39%, P = 0.0002) and the magnitude of the decrease after alcohol withdrawal was positively related to the duration of hospitalization.

APOA1 drug alcohol 8375458 In contrast to alcoholic men, studied previously by us using the same study design and methods, there was no significant elevation of HDL3 cholesterol and apo A I. APOA1 drug alcohol 1521980 Adjustment for age, body mass index, smoking, alcohol consumption, stress and tension at work, shift work, noise exposure and educational level in multiple linear regression analysis showed significant effects of the CS2 index on systolic BP, diastolic BP, cholesterol, HDL cholesterol, LDL cholesterol, apolipoprotein A1, apolipoprotein B, the LDL cholesterol/apolipoprotein B and HDL cholesterol/apolipoprotein A1 ratios; there were no significant effects on the triglycerides.

APOA1 addiction withdrawal 1410896 HDL cholesterol, apo A I and apo B showed a biphasic variation with significant post withdrawal changes which became less pronounced after 6 months of abstinence. APOA1 drug alcohol 3517775 STA, apoA lipoprotein, HDL cholesterol, total cholesterol and triglycerides were tested in 44 men dealt in 4 groups (subjects with normal or elevated STA, alcoholic or withdrawn). ABAT addiction reward 29381352 We previously designed the mechanism based inactivator (1S,3S) 3 amino 4 difluoromethylenyl 1 cyclopentanoic acid (2), now called CPP 115, that is 186 times more efficient in inactivating GABA AT than vigabatrin, the only FDA approved drug that is an inactivator of GABA AT. ABAT addiction reward 29381352 Herein we report the design, using molecular dynamics simulations, synthesis, and biological evaluation of a new mechanism based inactivator, (S) 3 amino 4 (difluoromethylenyl)cyclopent 1 ene 1 carboxylic acid (5), which was found to be almost 10 times more efficient as an inactivator of GABA AT than CPP 115. ABAT drug alcohol 22253714 There were also expression changes specific to cocaine addicts (GAD1, GAD2), alcoholics (GABRA2) and P rats (ABAT, GABRG3). ABAT drug cocaine 22253714 There were also expression changes specific to cocaine addicts (GAD1, GAD2), alcoholics (GABRA2) and P rats (ABAT, GABRG3). ABAT addiction addiction 22128851 Vigabatrin, a GABA aminotransferase (GABA AT) inactivator, is used to treat infantile spasms and refractory complex partial seizures and is in clinical trials to treat addiction. ABAT addiction reward 22128851 We evaluated a novel GABA AT inactivator (1S, 3S) 3 amino 4 difluoromethylenyl 1 cyclopentanoic acid (CPP 115, compound 1) and observed that it does not exhibit other GABAergic or off target activities and is rapidly and completely orally absorbed and eliminated. ABAT drug alcohol 16834758 Consistent with their ability to enhance the action of GABA at GABA(A) receptors, these steroid derivatives (termed neuroactive steroids) possess anticonvulsant, antidepressant and anxiolytic effects in addition to altering aspects of sexual and alcohol related behaviors. ABAT drug benzodiazepine 15926867 Non selective benzodiazepine (BZ) binding site full agonists, exemplified by diazepam, act by enhancing the inhibitory effects of GABA at GABA(A) receptors containing either an alpha1, 2, 3 or 5 subunit. ABAT drug benzodiazepine 15864560 In contrast, other BZ binding site ligands, such as 6 (2bromophenyl) 8 fluoro 4H imidazo [1,5 a][1,4] benzodiazepine 3 carboxamide (imidazenil), which fail to allosterically and positively modulate the action of GABA at GABA(A) receptors with alpha(1) subunits but that selectively allosterically modulate cortical GABA(A) receptors containing alpha(5) subunits, contribute to the anxiolytic, antipanic, and anticonvulsant actions of these ligands without producing sedation, amnesia, or tolerance. ABAT drug benzodiazepine 12434260 The behavioral effects of racemic zopiclone are similar to those of benzodiazepines that positively modulate GABA at the GABA(A) receptor complex; however, it is not clear how enantiomers or metabolites of zopiclone contribute to the benzodiazepine like behavioral effects of racemic zopiclone. ABAT drug alcohol 12108574 We propose that the N methyl D aspartate (NMDA) antagonist and gamma aminobutyric (GABA)mimetic properties of ethanol are responsible for its apoptogenic action, in that we have found that other drugs that block NMDA glutamate receptors or mimic GABA at GABA(A) receptors also trigger apoptotic neurodegeneration in the developing brain. ABAT addiction reward 11280926 "The reward cascade" involves the release of serotonin, which in turn at the hypothalmus stimulates enkephalin, which in turn inhibits GABA at the substania nigra, which in turn fine tunes the amount of DA released at the nucleus accumbens or "reward site." ABAT drug alcohol 10604976 Although it is well documented that chronic ethanol (EtOH) administration produces cross tolerance to the positive modulatory effect of benzodiazepines and GABA at GABA(A) receptors, recent findings suggest that sensitivity to 3alpha,5alpha P is enhanced during EtOH withdrawal.

ABAT drug alcohol 9361331 The results of the present study provide further evidence of the similarities between the effects of ethanol and benzodiazepine receptor agonists on learning and memory, and are consistent with the hypothesis that ethanol's potentiation of GABA at GABAA receptors contributes to the learning and memory impairments produced by ethanol.

ABAT drug alcohol 26735441 We have studied the activities of the GABA metabolizing enzymes GABA aminotransferase (GABA AT), succinic semialdehyde dehydrogenase (SSA DH) and SSA reductase (SSA R) and the levels of GABA, glutamine and glutamate in rats preferring water (WP) or ethanol (EP) after 6 months of ethanol consumption and 12 hours to 7 days after withdrawal.

ABAT drug alcohol 26735441 We showed decreased GABA levels in the brain stem, decreased GABA AT activity in the hemispheres and brain stem, and enhanced GABA AT activity in the striatum of EP rats compared with the control or WP animals following chronic consumption of ethanol. ABAT drug alcohol 8730228 These results suggest that neither low plasma GABA at baseline nor altered plasma GABA response to diazepam is associated with increased genetic risk for alcoholism. ABAT drug benzodiazepine 8730228 These results suggest that neither low plasma GABA at baseline nor altered plasma GABA response to diazepam is associated with increased genetic risk for alcoholism. ABAT drug alcohol 7841849 The neurochemical basis for the rewarding effects of alcohol may be the potentiation of GABA at GABAA receptors (causing relaxation) and release of dopamine from mesolimbic neurones (causing euphoria). ABAT drug benzodiazepine 3016590 The effect of drugs which down regulate the function of GABA at the level of the GABA/benzodiazepine receptor complex was studied on the conflict test in the rat. ABAT drug alcohol 6152602 The increase in striatal GABA at day 7 of withdrawal after 30 days of ethanol may be a rebound phenomenon and may reflect the presence of a hypogabaergic state which has been shown to occur during ethanol withdrawal.

GSTM1 drug nicotine 12507920 CYP1A1 and GSTM1 genotypes affect benzo[a]pyrene DNA adducts in smokers' lung: comparison with aromatic/hydrophobic adduct formation. GSTM1 drug nicotine 12507920 In this review, we summarize the published data on modulation of (+) anti BPDE DNA adduct levels in smokers' lungs by CYP1A1*2 genotypes alone or in combination with GSTM1 polymorphism and compare these results with those reported for aromatic/hydrophobic (bulky) DNA adducts. GSTM1 addiction dependence 12507920 In contrast, a clear dependence of (+) anti BPDE DNA adduct levels was found as a function of the CYP1A1 and GSTM1 genotypes: In lung parenchyma, this adduct was more pronounced in persons with the GSTM1*0 genotype, and CYP1A1*2 GSTM1*0 carriers had higher (+) anti BPDE DNA adduct levels than those with CYP1A1*1/*1 GSTM1*0. GSTM1 drug nicotine 11815259 Smoking and GSTM1 genotype were significant predictors for log transformed 1 OHPG by multiple regression analysis (overall model R(2)=0.565, P<0.001), whereas smoking was the only significant predictor for log transformed aromatic DNA adducts (overall model R(2)=0.249, P=0.201). GSTM1 drug nicotine 11815259 Our results suggest that the significant increase in urinary 1 OHPG in the exposed workers is due to higher prevalence of smokers among them, and that the association between urinary PAH metabolites and aromatic DNA adducts in workers of industrial waste handling may be modulated by GSTM1 genotype.

GSTM1 drug nicotine 10667460 Some CYP1A1/GSTM1 0/0 genotype combinations seem to predispose the lung, esophagus, and oral cavity of smokers to an even higher risk for cancer or DNA damage, requiring, however, confirmation. GSTM1 drug nicotine 10026994 BPDE DNA adduct levels in bronchial tissue of smokers with high pulmonary CYP1A1 inducibility (by immunohistochemistry) and GSTM1 inactive were approximately 100 fold higher than in subjects with an active GSTM1 at similar smoking dose. GSTM1 drug nicotine 10026994 Further genetic analyses confirmed that the combination of CYP1A1 homozygous mutants and GSTM1 inactive leads to high levels of BPDE DNA adducts in human lung of smokers and white blood cells of PAH exposed coke oven workers. GSTM1 drug nicotine 9921921 After grouping by the smoking status, among smokers in both cancer groups (62.1% in lung cancer and 71.4% in the bladder cancer group, respectively) there were statistically significantly (p < 0.05) increased frequencies of the GSTM1 deletion genotype as compared to the control group (49.6%). GSTM1 drug nicotine 9921921 Smokers with absence of the GSTM1 gene were at an approximately 1.7 fold higher risk for lung cancer (odds ratio OR = 1.67, 95% confidence interval CI 95% = 1.0 2.7, p = 0.04) and an approximately 2.5 fold higher risk for bladder cancer (OR = 2.54, CI 95% = 1.2 5.5, p = 0.02). GSTM1 addiction dependence 9921921 The findings suggest that the GSTM1 null genotype may be associated with susceptibility to lung and urinary bladder cancer in dependence on the exposure to carcinogens in cigarette smoke and that the GSTT1 null genotype is not a critical factor in mediating the risk of lung cancer, but may be associated with an increased susceptibility to bladder cancer.

GSTM1 drug opioid 9160346 From behavioral, biochemical and molecular biological studies, it is suggested so far that development of physical dependence on morphine results predominantly from an activation of mu 1 and mu 2 opioid receptors which causes functional changes in Gi/o, adenylate cyclase, protein kinases A and C, beta adrenoceptor and NMDA receptor in the locus coeruleus.

CYP1A1 drug alcohol 29886839 Ethanol decreased CYP1A1 mRNA expression relative to control (P=0.02), and combined ethanol+NNK exposures decreased the expression of CYP1A1 (P=0.01) and CYP2C6 (P=0.03). CYP1A1 drug alcohol 29404485 The number of EVs and the amounts of EV CYP2E1, CYP2A, CYP1A1/2, and CYP4B proteins were markedly elevated in both patients with alcoholism and alcohol exposed rats and mice. CYP1A1 drug nicotine 28816414 Prior epigenome wide association studies indicate that methylation status at cg05575921, a CpG residue located in the aryl hydrocarbon receptor repressor (AHRR) gene, may be a robust indicator of smoking status in individuals with as little as half of a pack year of smoking. CYP1A1 drug nicotine 26356606 Smoking, Methylation at AHRR, and Recidivism Risk in a Community Correction Sample of Individuals at High Risk for Recidivism. CYP1A1 drug nicotine 25233467 We evaluated 23 single nucleotide polymorphisms (SNPs) in the five nicotinic receptor related genes (CHRNB3, CHRNA6, and CHRNA5/A3/B4) previously reported to be associated with lung cancer risk and smoking behavior and 14 SNPs in the four 'control' genes (TERT, CLPTM1L, CYP1A1, and TP53), which were not reported in the smoking GWA studies. CYP1A1 drug nicotine 25052559 Several statistically significant interactions were observed between smoking and genetic variants (CYP1A2 1548C>T, CYP1A1 3801T>C, CYP1B1 4326G>C, NAT1 c. 85 1014T>A, UGT1A7 W208R 622T>C, SOD2 c.47T>C, GSTT1 deletion). CYP1A1 drug alcohol 24663500 The expression and activity of CYP1A1, 2B6 and 2E1 were carried out in the cells exposed to CYP inducers viz., 3 methylcholanthrene (3 MC), cyclophosphamide (CPA), ethanol and known neurotoxicant monocrotophos (MCP), a widely used organophosphorous pesticide. CYP1A1 drug nicotine 23840148 Combination of the CYP1A1 2C and NQO1 609CC genotypes was associated with a decreased risk of colorectal adenomas regardless of smoking status. CYP1A1 addiction sensitization 19789301 Treatment with 17 AAG, an Hsp90 inhibitor, caused a marked decrease in levels of AhR; inhibited UVR , aTRP , and FICZ mediated induction of CYP1A1 and CYP1B1; and blocked the sensitization of HaCaT cells to B[a]P induced DNA adduct formation. CYP1A1 drug nicotine 19563927 Cytochrome P450 1A1 (CYP1A1) is a key enzyme that metabolizes the cigarette toxin relevant to smoking induced atherogenesis. CYP1A1 drug nicotine 19563927 This case control study examined the role of CYP1A1 polymorphisms, CYP1A1 2A (T6235C) and CYP1A1 2C (A4889G), in susceptibility to smoking related CAD. CYP1A1 drug nicotine 19563927 The beneficial effect of the CYP1A1 2C G/G genotype was even greater for never smokers than those carrying the A/A genotype (OR=0.23, 95% CI=0.08 0.71). CYP1A1 drug nicotine 19563927 Our findings suggest that the CYP1A1 2C G/G genotype may reduce the risk for CAD in the Taiwanese population and this effect appeared to be more pronounced among never smokers.

CYP1A1 drug nicotine 12507920 In this review, we summarize the published data on modulation of (+) anti BPDE DNA adduct levels in smokers' lungs by CYP1A1*2 genotypes alone or in combination with GSTM1 polymorphism and compare these results with those reported for aromatic/hydrophobic (bulky) DNA adducts. CYP1A1 addiction dependence 12507920 In contrast, a clear dependence of (+) anti BPDE DNA adduct levels was found as a function of the CYP1A1 and GSTM1 genotypes: In lung parenchyma, this adduct was more pronounced in persons with the GSTM1*0 genotype, and CYP1A1*2 GSTM1*0 carriers had higher (+) anti BPDE DNA adduct levels than those with CYP1A1*1/*1 GSTM1*0. CYP1A1 drug nicotine 23889309 Smokers from the exposed group had higher adduct levels when they were CYP1A1 *1/*1 wild type rather than heterozygous and homozygous for the variant alleles (CYP1A1 *1/*2 plus *2/*2) (p = 0:01). CYP1A1 drug nicotine 23889309 The dependence of BPDE SA adduct levels and frequency on the CYP1A1 *1/*1 genotype was most pronounced in GSTM1 deficient smokers.

CYP1A1 drug nicotine 10667460 We summarize here the results of case control studies published since 1990 on the effects of genetic variants of CYP1A1, 1A2, 1B1, 2A6, 2D6, 2E1, 2C9, 2C19, 17, and 19 alone or in combination with detoxifying enzymes as modifiers of the risk for tobacco related cancers. CYP1A1 drug nicotine 10667460 Some CYP1A1/GSTM1 0/0 genotype combinations seem to predispose the lung, esophagus, and oral cavity of smokers to an even higher risk for cancer or DNA damage, requiring, however, confirmation. CYP1A1 drug nicotine 10026994 BPDE DNA adduct levels in bronchial tissue of smokers with high pulmonary CYP1A1 inducibility (by immunohistochemistry) and GSTM1 inactive were approximately 100 fold higher than in subjects with an active GSTM1 at similar smoking dose. CYP1A1 drug nicotine 10026994 Further genetic analyses confirmed that the combination of CYP1A1 homozygous mutants and GSTM1 inactive leads to high levels of BPDE DNA adducts in human lung of smokers and white blood cells of PAH exposed coke oven workers. CYP1A1 drug alcohol 7786308 Both proteins were induced significantly by chronic ethanol administration (CYP1A1, 1.9 fold; CYP2B1, 4 fold). COMETT drug nicotine 31127298 Each of the fourteen TCORS, and two other NIH funded research programs, the Center for the Evaluation of Nicotine in Cigarettes (CENIC) and the Consortium on Methods Evaluating Tobacco (COMET), pursued specific research themes relevant to FDA's priorities. COMETT drug nicotine 31127298 The Tobacco Centers of Regulatory Science, CENIC, and COMET have had a high output of scientific articles since 2013. COMETT drug amphetamine 28138562 Pulmonary artery endothelial cells (PAECs) from AMPH associated PAH patients show DNA damage as judged by γH2AX foci and DNA comet tails. COMETT drug amphetamine 25867833 In this study, we examined the effect of METH on DNA damage in vivo using the single cell gel electrophoresis assay (comet assay) under two different conditions. COMETT drug cocaine 25264678 We assessed genome instability by means of the comet assay and the cytokinesis block micronucleus technique in crack cocaine users at the time of admission to a rehabilitation clinic and at two times after the beginning of withdrawal. COMETT addiction withdrawal 25264678 We assessed genome instability by means of the comet assay and the cytokinesis block micronucleus technique in crack cocaine users at the time of admission to a rehabilitation clinic and at two times after the beginning of withdrawal. COMETT addiction aversion 23271343 CTA, MN, and comet assay frequency were significantly greater in polyvinyl chloride (PVC) factory workers (p < 0.05) with long duration work. COMETT addiction aversion 23271343 CTA, MN, and comet assay values were found to be increased with age in exposed subjects as well as in controls, with exposed subjects showing a statistically greater degree. COMETT drug cocaine 21071548 The purpose of the present study was to characterize the genetic damage induced by paradoxical sleep deprivation (PSD) in combination with cocaine or ecstasy (3,4 methylenedioxymethamphetamine; MDMA) in multiple organs of male mice using the single cell gel (comet) assay.

COMETT drug alcohol 20958327 Oxidative DNA damage, possible metabolic pathways of ethanol in human peripheral lymphocytes, and the repair system involved in the DNA auto repair process were examined by comet assay, flow cytometry, time of flight mass spectrometry (TOF MS), reverse transcription polymerase chain reaction (RT PCR), and western blotting. COMETT drug alcohol 18684230 The present study, by the use of single cell gel electrophoresis (comet assay), investigated the potential genotoxicity of acute and long term ethanol administration in mouse peripheral leucocytes. COMETT drug psychedelics 17762515 In particular, we examined whether administration of MDMA, at doses producing hippocampal hyperexcitability also produces rearrangements of DNA strands measured by the comet assay. COMETT drug nicotine 17610937 Comet assay was performed for 18 smokers, 143 ETS exposed subjects and 130 non smokers to measure DNA damage. COMETT drug nicotine 17610937 The results of this study suggest that comet assay are reliable biomarkers for monitoring pregnant women exposed to tobacco smoke and indicate fetal growth effects from environmental exposure to tobacco smoke. COMETT drug alcohol 17567031 By using the single cell gel electrophoresis (comet assay), a simple and sensitive technique for genotoxicity studies, the potential genotoxicity of acute and chronic ethanol administration in the different brain regions was investigated. COMETT drug alcohol 16705883 Limitations and critical features presently linked to comet test applications, with particular regard to the biomonitoring of individuals exposed to genotoxic agents, include: lack of sensitivity with respect to aneugens (agents inducing numerical chromosomal aberrations), possible underestimation of genotoxic potency of agents with mixed action mechanisms, sensitivity depending on the genotoxic agent itself, dependence an biological substrate with regard to the influence of cytotoxicity on the assay results, influence of age, tobacco smoke, alcohol and drug consumption, diet, kinetics of DNA adducts and DNA repair mechanisms.

COMETT drug nicotine 15858221 To assess the genotoxicity of nicotine, the DNA damaging effect on human lymphocytes and target cells from lymphatic tissue of the palatine tonsils from 10 healthy patients was tested with the alkaline single cell microgel electrophoresis (Comet) assay. COMETT drug alcohol 14700736 Exposure of canine cerebral vascular smooth muscle cells (VSMCs) to ethanol (10, 25 and 100 mM) for 1, 3 and 5 days induced apoptosis with its typical characteristics of nuclear shrinkage, condensation, and DNA breakage as well as formation of apoptotic bodies observed by fluorescence staining, terminal deoxyribonucleotidyl transferase mediated dUTP nick end labeling and comet assays. COL11A2 drug cocaine 32641757 Interestingly, acute or chronic cocaine exposure downregulated miR 124 levels concomitant with upregulation of PARP 1 protein in dopaminergic like neuronal cells in culture. COL11A2 drug cocaine 32641757 Collectively, these studies identify Parp 1 as a direct target of miR 124 in neuronal cells, establish miR 124 as a cocaine regulated miRNA in the mouse NAc, and highlight a novel pathway underlying the molecular effects of cocaine. COL11A2 drug amphetamine 32086884 In addition, to explore METH induced neurotoxicity, we measured the level of Parkin and the phosphorylation levels of α syn, Polo like kinase 2 (PLK2), the proteasome activity marker CD3δ, and the apoptosis related proteins Caspase 3 and PARP. COL11A2 drug alcohol 31251945 PARP inhibition in vivo blocks alcohol induced brain neurodegeneration and neuroinflammatory cytosolic phospholipase A2 elevations. COL11A2 drug alcohol 31251945 Concurrent with neurodegeneration, alcohol elevates poly (ADP ribose) polymerase 1 (PARP 1) and cytosolic phospholipase A2 (cPLA2) levels. COL11A2 drug alcohol 31251945 Inhibitors of PARP exert in vitro neuroprotection while suppressing cPLA2 elevations in alcohol treated HC ECX slice cultures. COL11A2 drug alcohol 31251945 Here, we examined in vivo neuroprotection and cPLA2 suppression by the PARP inhibitor, veliparib, in a recognized adult rat model of alcohol binging. COL11A2 drug alcohol 31251945 These in vivo results support an emerging key role for PARP in binge alcohol induced neurodegeneration and cPLA2 related neuroinflammation.

COL11A2 addiction intoxication 29339456 Using rat adult age hippocampal entorhinal cortical (HEC) slice cultures, we examined the role of poly [ADP ribose] polymerase (PARP) in binge ethanol's brain inflammatory and neurodegenerative mechanisms. COL11A2 drug alcohol 29339456 Previously, we found that brain PARP1 levels were upregulated by neurotoxic ethanol binges in adult rats and HEC slices, and PARP inhibitor PJ34 abrogated slice neurodegeneration. COL11A2 drug alcohol 29339456 After verifying that PJ34 effectively blocks PARP activity (↑PAR), we demonstrated that, like PJ34, three other PARP inhibitors olaparib, veliparib, and 4 aminobenzamide provided neuroprotection from ethanol. COL11A2 drug alcohol 29339456 Importantly, PJ34 and olaparib also prevented ethanol's amplification of the PLA2 isoenzymes, and two PLA2 inhibitors were neuroprotective thus coupling PARP to PLA2, with PLA2 activity promoting neurodegeneration. COL11A2 drug alcohol 29339456 Also, PJ34 and olaparib blocked ethanol induced HMGB1 elevations, linking brain PARP induction to TLR4 activation.

COL11A2 drug cocaine 27595592 PARP 1 is required for retrieval of cocaine associated memory by binding to the promoter of a novel gene encoding a putative transposase inhibitor. COL11A2 drug cocaine 27595592 We demonstrate herein that auto poly(ADP ribosyl)ation of activated PARP 1 was significantly pronounced during retrieval of cocaine associated contextual memory, in the central amygdala (CeA) of rats expressing cocaine conditioned place preference (CPP). COL11A2 addiction reward 27595592 We demonstrate herein that auto poly(ADP ribosyl)ation of activated PARP 1 was significantly pronounced during retrieval of cocaine associated contextual memory, in the central amygdala (CeA) of rats expressing cocaine conditioned place preference (CPP).

COL11A2 drug alcohol 27527870 Ethanol caused both apoptotic and necrotic cell death which was demonstrated by the increase in active caspase 3, caspase 8, cleaved PARP, cleaved CK 18 and the secretion of high mobility group protein B1 (HMGB1). COL11A2 drug psychedelics 26068050 In fact, chronic MDMA inhibited proteins of the apoptotic pathway (i.e., pro apoptotic FADD, Bax and cytochrome c) leading to an inhibition of cell death markers (i.e., p JNK1/2, cleavage of PARP 1) and suggesting regulatory mechanisms in response to the neurochemical changes caused by the drug. COL11A2 drug amphetamine 25631491 In addition, blocking caspase 11 expression inhibited METH induced activation of caspase 3 and PARP in vitro and in vivo, suggesting that caspase 11/caspase 3 signal pathway is involved in METH induced neurotoxicity. COL11A2 drug alcohol 25029343 We report here that neurotoxic binge ethanol exposure produces comparable significant effects in vivo and in vitro on adult rat brain levels of AQP4 as well as neuroinflammation linked enzymes: key phospholipase A2 (PLA2) family members and poly (ADP ribose) polymerase 1 (PARP 1).

COL11A2 drug alcohol 25029343 Furthermore, supplementation with docosahexaenoic acid (DHA; 22:6n 3), known to quell AQP4 and neurodegeneration in ethanol treated slices, blocked PARP 1 and PLA2 changes while counteracting endogenous DHA reduction and increases in oxidative stress footprints (3 nitrotyrosinated proteins).

COL11A2 drug cocaine 24449909 Using PARP 1 inhibitors and viral mediated gene transfer, we established that PARP 1 induction in NAc mediates enhanced behavioral responses to cocaine, including increased self administration of the drug. COL11A2 drug cocaine 24449909 Using chromatin immunoprecipitation sequencing, we demonstrated a global, genome wide enrichment of PARP 1 in NAc of cocaine exposed mice and identified several PARP 1 target genes that could contribute to the lasting effects of cocaine. COL11A2 drug cocaine 24449909 Specifically, we identified sidekick 1 important for synaptic connections during development as a critical PARP 1 target gene involved in cocaine's behavioral effects as well as in its ability to induce dendritic spines on NAc neurons. COL11A2 drug cocaine 24449909 These findings establish the involvement of PARP 1 and PARylation in the long term actions of cocaine. COL11A2 drug opioid 24281942 In the HPC, morphine significantly increased the ratio of Bax/Bcl 2, caspases 3, and PARP by the lowest dose (0.5 mg/kg), but, in the VTA, a considerable increase was seen in the dose of 5 mg/kg; promotion of apoptotic factors in the HPC and VTA insinuates that morphine can affect the molecular mechanisms that interfere with apoptosis through different receptors. COL11A2 drug opioid 24096212 In the NAc, morphine significantly increased the Bax/Bcl 2 ratio, caspase3 and PARP in the lowest dose (0.5mg/kg) but in the PFC considerable increase was seen in dose of 5mg/kg.

COL11A2 drug cocaine 21925237 In the same brain samples of cocaine abusers, the proteolytic cleavage of PARP 1 was increased (+39%). COL11A2 drug cocaine 21925237 Chronic exposure to cocaine in rats, including withdrawal for 3 days, did not alter Fas FADD receptor complex, cytochrome c, caspase 3/fragments, AIF, PARP 1 cleavage, and associated signaling in the cerebral cortex.

CAV1 drug opioid 27726130 This study reveals that chronic opioid exposure of μ opioid receptor (MOR) expressing Chinese hamster ovary cells (MOR CHO) and chronic in vivo morphine exposure of rat spinal cord augmented recruitment of multiple components of MOR adenylyl cyclase (AC) stimulatory signaling by caveolin 1. CAV1 drug opioid 27726130 Strikingly, in MOR CHO and spinal cord, blocking the caveolin 1 scaffolding domain substantially attenuated the chronic morphine induced increased interaction of caveolin 1 with MOR, Gsα, protein phosphatase 2A (PP2A), and AC.

RGS4 drug opioid 12653973 Intracellular application of wild type RGS4, but not a GTPase accelerating deficient mutant of RGS4, into LC neurons diminished electrophysiological responses to morphine. RGS4 drug opioid 12653973 The observed subtype and time specific regulation of RGS4 protein and mRNA, and the diminished morphine induced currents in the presence of elevated RGS4 protein levels, indicate that morphine induction of RGS4 could contribute to aspects of opiate tolerance and dependence displayed by LC neurons.

HDAC2 addiction intoxication 31056842 Memory and plasticity impairment after binge drinking in adolescent rat hippocampus: GluN2A/GluN2B NMDA receptor subunits imbalance through HDAC2. HDAC2 addiction intoxication 31056842 In conclusion, the memory impairing effects of two binge like EtOH exposure involve NMDA receptor dependent LTD deficits due to a GluN2A/GluN2B imbalance resulting from changes in GluN2B expression induced by HDAC2. HDAC2 drug alcohol 30851364 The goal of this study was to examine depression like behavior during alcohol withdrawal and associated changes in histone acetylation and expression of histone deacetylase 2 (HDAC2) in the hippocampus, a brain region critical for mood regulation and depression.

HDAC2 addiction withdrawal 30851364 In a separate group of rats, the hippocampus was analyzed for mRNA and protein expression of HDAC2 and levels of histone H3 lysine 9 acetylation (H3K9ac) during chronic ethanol exposure and withdrawal. HDAC2 drug alcohol 30851364 Rats undergoing ethanol withdrawal exhibited depression like behavior and had increased HDAC2 and decreased H3K9ac levels in specific structures of the hippocampus. HDAC2 addiction withdrawal 30851364 Rats undergoing ethanol withdrawal exhibited depression like behavior and had increased HDAC2 and decreased H3K9ac levels in specific structures of the hippocampus. HDAC2 addiction withdrawal 30851364 Treatment with SAHA during withdrawal ameliorated depression like behavior and normalized changes in hippocampal HDAC2 and H3K9ac levels. HDAC2 drug amphetamine 30811820 We found that METH increased H4ac in class IIa Hdac4 and Hdac5 and decreased H3/H4ac at class I Hdac1, Hdac2, and Hdac8. HDAC2 drug amphetamine 30811820 At the mRNA level, repeated METH increased Hdac4 and decreased Hdac2. HDAC2 addiction withdrawal 30103280 EtOH withdrawal was associated with increased HDAC2 and decreased acH3K9 protein levels; SAHA treatment normalized acH3K9 levels. HDAC2 drug amphetamine 30056065 In this study, we measured the effects of single dose injections of modafinil and METH on the protein levels of acetylated histone H3 (H3ac) and H4ac, deacetylases HDAC1 and HDAC2, and of the NMDA subunit GluN1 in the medial PFC (mPFC) of mice euthanized 1 h after drug administration. HDAC2 drug amphetamine 30056065 Acute modafinil and METH injections caused similar effects on total histone acetylation, increasing H3ac and decreasing H4ac, and they also increased HDAC1, HDAC2 and GluN1 protein levels in the mouse mPFC. HDAC2 drug alcohol 29520058 We found that chronic ethanol exposure using either ethanol gavage or two bottle choice voluntary access paradigms decreased Gabra1 expression and increased Hdac2 and Hdac3 expression. HDAC2 drug alcohol 29520058 Administration of the HDAC inhibitor trichostatin A (TSA) after chronic ethanol exposure prevents the decrease in Gabra1 expression and function as well as the increase in Hdac2 and Hdac3 expression in both the cortex and the medial prefrontal cortex (mPFC). HDAC2 drug alcohol 29520058 Chronic ethanol exposure and withdrawal, but not acute ethanol exposure or acute withdrawal, cause a selective upregulation of HDAC2 and HDAC3 associated with the Gabra1 promoter that accompanies a decrease in H3 acetylation of the Gabra1 promoter and the reduction in GABAAR α1 subunit expression. HDAC2 addiction withdrawal 29520058 Chronic ethanol exposure and withdrawal, but not acute ethanol exposure or acute withdrawal, cause a selective upregulation of HDAC2 and HDAC3 associated with the Gabra1 promoter that accompanies a decrease in H3 acetylation of the Gabra1 promoter and the reduction in GABAAR α1 subunit expression. HDAC2 drug alcohol 28174112 Additionally, innately higher expression of the HDAC2 isoform leads to a deficit in global and gene specific histone acetylation in the amygdala that is associated with a decrease in the expression of several synaptic plasticity associated genes and maintaining heightened anxiety like behavior and excessive alcohol intake. HDAC2 drug alcohol 28174112 Adolescent alcohol exposure also leads to higher expression of HDAC2 and a deficit in histone acetylation leading to decreased expression of synaptic plasticity associated genes and high anxiety and drinking behavior in adulthood. HDAC2 drug opioid 27306674 Using a combination of immunohistochemistry, Western blot, and whole cell patch clamp recording in rat midbrain slices, we show that morphine increased HDAC2 activity in VTA DA neurons and reduced histone H3 acetylation at lysine 9 (Ac H3K9) in the VTA 24 h after the injection. HDAC2 drug opioid 27306674 Our results suggest that acute morphine induced changes in VTA DA activity and synaptic transmission engage HDAC2 activity locally in the VTA to maintain synaptic modifications through histone hypoacetylation.

HDAC2 drug cocaine 24527678 Gene expression of histone deacetylase 2 and glutamate receptor kainate 1 were only increased by cocaine treatment. HDAC2 drug amphetamine 24239129 Methamphetamine exposure also increased repressor element 1 silencing transcription factor (REST) corepressor 1, methylated CpG binding protein 2, and histone deacetylase 2 enrichment, but not of sirtuin 1 or sirtuin 2, onto GluA1 and GluA2 gene sequences. HDAC2 drug amphetamine 24239129 Moreover, METH caused interactions of REST corepressor 1 and methylated CpG binding protein 2 with histone deacetylase 2 and of REST with histone deacetylase 1. HDAC2 drug alcohol 23485013 We employed HDAC2 small interfering RNA infusion into the central nucleus of amygdala (CeA) of P rats to determine the causal role of HDAC2 in anxiety like and alcohol drinking behaviors. HDAC2 drug alcohol 23485013 Acute ethanol exposure decreased amygdaloid HDAC activity and HDAC2 protein levels, increased global and gene (Bdnf and Arc) specific histone acetylation, and attenuated anxiety like behaviors in P rats but had no effects in NP rats. HDAC2 drug alcohol 23485013 The HDAC2 knockdown in the CeA attenuated anxiety like behaviors and voluntary alcohol but not sucrose consumption in P rats and increased histone acetylation of Bdnf and Arc with a resultant increase in protein levels that correlated with increased dendritic spine density. HDAC2 drug alcohol 23485013 These novel data demonstrate the role of HDAC2 mediated epigenetic mechanisms in anxiety and alcoholism. HDAC2 drug alcohol 23474591 Here, we investigated modulation of withdrawal induced changes in GABA sensitivity of pDAergic VTA neurons by HDAC inhibitors (HDACi), and also measured the levels of HDAC2, histone (H3 K9) acetylation, and GABA Aα1 receptor (GABA (A α1) R) subunit in VTA during ethanol withdrawal.

HDAC2 addiction addiction 21447001 Although HDACs and HDIs have been associated with drug addiction, there is no evidence of the neurodegenerative role of HDAC2 and neuroprotective role of TSA in alcohol addiction. HDAC2 drug alcohol 21447001 Therefore, we hypothesize that alcohol modulates HDAC2 through mechanisms involving oxidative stress. HDAC2 drug alcohol 21447001 To test our hypothesis, the human neuronal cell line, SK N MC, was treated with different concentrations of ethanol (EtOH); HDAC2 gene and protein expression were assessed at different time points. HDAC2 drug alcohol 21447001 Additionally, alcohol significantly induced ROS, and pharmacological inhibition of HDAC2 with TSA was shown to be neuroprotective by significantly inhibiting HDAC2 and ROS. HDAC2 drug alcohol 21447001 These results suggest that EtOH can upregulate HDAC2 through mechanisms involving oxidative stress and HDACs may play an important role in alcohol use disorders (AUDs). HDAC2 drug nicotine 21166804 We measured immunohistochemically the acetylation of lysine 9 of histone H3, and the expression of phosphorylated cAMP response element binding protein, HDAC2 and methyl CpG binding protein 2 in the striatum and prefrontal cortex of rats displaying nicotine preference or aversion and treated with phenylbutyrate.

HDAC2 drug nicotine 21166804 Moreover, striatal expression of HDAC2 in response to phenylbutyrate mirrored the behavioral effects of the inhibitor, suggesting that HDAC2 is involved in promoting synaptic plasticity underlying the preference for nicotine. HDAC2 drug cocaine 19939859 Cocaine self administration was accompanied by an increased synthesis of Mecp2, HDAC2 and HDAC11 and by a decreased nuclear localization of HDAC5 and of the phospho form of HDAC5, suggesting a nuclear export of this protein in response to the drug.

GRM3 drug alcohol 31070489 The metabotropic glutamate receptor subtype 3 knockout (mGluR3 KO) mouse line was used to study alcohol induced place preference, locomotor activating and ataxic effects, limited access alcohol drinking, and preference for sucrose and saccharin. GRM3 drug alcohol 31070489 Alcohol induced horizontal locomotor stimulation and reduced rearing behaviour remained unchanged in the mGluR3 KO mice. GRM3 drug alcohol 31070489 However, alcohol induced place conditioning in an unbiased paradigm setup was lacking in the mGluR3 KO mice, but clearly present in wildtype mice. GRM3 drug alcohol 31070489 Alcohol consumption, studied through the 'drinking in the dark' model, remained unchanged in the mGluR3 KO mice, although low consumption in both wildtype and knockout mice hampers interpretation. GRM3 drug amphetamine 30950164 Shati/Nat8l overexpression in the nucleus accumbens (NAc) attenuates the pharmacological response to METH via mGluR3.

GRM3 addiction addiction 25802079 Based on rodent studies, group II metabotropic glutamate receptors (mGluR2 and mGluR3) were suggested as targets for addiction treatment. GRM3 drug cocaine 25539508 An overall decrease was observed in the mRNA expression of the glutamate synthesizing gene kidney type glutaminase (KGA), the metabotropic glutamate receptors (mGluR3 and GluR), and subunits of NMDA ionotropic receptors (NR1, NR2A, NR2B and NR2C) after acute cocaine administration, while mice repeatedly exposed to cocaine only displayed an increase in NR2C. GRM3 drug cocaine 25539508 However, in cocaine sensitized mice primed with cocaine, this inhibition was reversed and a strong increase was detected in the mGluR5, NR2 subunits, and both GluR1 and GluR3.

GRM3 addiction addiction 23624743 Another possibility to study the contributions of mGluR2 and mGluR3 in mediating addictive like behavior is the use of knockout models. GRM3 addiction reward 23624743 Because mGluR2 knockouts cannot be used in operant procedures due to motoric impairment, we only tested mGluR3 knockouts. GRM3 drug benzodiazepine 23392308 The mRNA expression levels of mGluR2 and mGluR3 were lowered in the cerebral cortex of mice pretreated with diazepam or alprazolam.

AURKA drug nicotine 20423277 Distribution of initiated contraceptive methods and of examinations and tests included, application of limits and contraindications in relation to age, smoking, body mass index or weight, blood pressure (BP) and migraine with aura when prescribing CHC (combined oral contraceptives (COCs), vaginal ring and contraceptive patch). AURKA drug nicotine 19788473 Symptoms of CA were associated with female gender, body mass index, current smoking, presence of aura, chronic headaches, transformed headaches, severe headache related disability, and duration of migraine illness from onset. AURKA addiction withdrawal 19271947 The newest combined oral contraceptive formulations are generally well tolerated in migraine without aura, and the majority of migraine without aura sufferers do not show any problems with their use; nevertheless, the last International Classification of Headache Disorders identifies at least two entities evidently related to the use of combined oral contraceptives: exogenous hormone induced headache and estrogen withdrawal headache. AURKA drug nicotine 19271947 Other risk factors (tobacco use, hypertension, hyperlipidemia, obesity and diabetes) must be carefully considered when prescribing combined oral contraceptives in migraine without aura patients, in particular in women aged over 35 years. AURKA drug nicotine 19200688 The toxicity is higher among female smokers, especially when they have several risk factors such as oral contraceptiveS and migraine with aura. SP1 drug amphetamine 29158267 In the present study, we hypothesized that METH impacts HIV infection of neural progenitor cells (NPCs) by a mechanism encompassing NFκB/SP1 mediated HIV LTR activation. SP1 drug amphetamine 29158267 METH treatment induced transcriptional activity of the HIV LTR promotor, an effect that required both NFκB and SP1 signaling. SP1 drug amphetamine 29158267 This study indicates that METH increases HIV infectivity of NPCs, through the NFκB/SP1 dependent activation of the HIV LTR and with the subsequent alterations of NPC neurogenesis. SP1 drug opioid 29067285 The pharmacologic protocol (SP1) for infants treated between 2005 and March 2014 (n = 146) dosed oral morphine every 4 h and utilized phenobarbital as adjuvant therapy. SP1 drug opioid 29067285 The length of morphine therapy was decreased by 8.5 days from 35 to 26.5 days (95% CI 4.5 12 days) for infants treated with SP2 vs. SP1 (p < 0.001). SP1 drug nicotine 24089524 Nicotine induces the up regulation of the α7 nicotinic receptor (α7 nAChR) in human squamous cell lung cancer cells via the Sp1/GATA protein pathway. SP1 drug nicotine 24089524 ChIP assays showed that nicotine induced the binding of GATA4 or GATA6 to Sp1 on the α7 nAChR promoter, thereby inducing its transcription and increasing its levels in human SCC L. Our data are clinically relevant because SCC L patients smoked for decades before being diagnosed with cancer. SP1 drug opioid 15501527 The substance P (SP) heptapeptide fragment SP1 7 alters the density of dopamine receptors in rat brain mesocorticolimbic structures during morphine withdrawal. SP1 addiction withdrawal 15501527 The substance P (SP) heptapeptide fragment SP1 7 alters the density of dopamine receptors in rat brain mesocorticolimbic structures during morphine withdrawal. SP1 drug nicotine 11509018 To test this hypothesis we examined the association of the C 45T promoter polymorphism in the Sp1 binding region of the CCK gene with smoking and BMI in two independent groups of subjects. SP1 drug alcohol 10889557 Recently, a number of studies have indicated that a C 36 to T transition in the CCK gene promoter Sp1 element4 (Figure 1) is associated with alcoholism and withdrawal symptoms as well as panic disorder.5 7 Moreover, it has been proposed that the polymorphism plays a direct role in the pathogenesis of the disorders by decreasing the expression and synthesis of CCK peptides.

SP1 addiction dependence 10611471 These results suggest the possibility that decreased SP1 dependent gene transcription in the rat cortex and hippocampus may be associated with the molecular mechanisms of ethanol dependence. SP1 drug alcohol 10604945 Hsc70 promoter constructs with diminished ethanol responsiveness in NG108 15 cells similarly had decreased transcriptional activation by exogenous Sp1 in Drosophila SL2 cells. SP1 drug alcohol 10604945 Some artificial promoter constructs containing multiple Sp1 sites were highly responsive to ethanol, but others were not, suggesting that the organization of the proximal promoter region was an additional factor that affected the ethanol response. SP1 drug alcohol 10604945 However ethanol exposure did not alter Sp1 DNA binding activity. SP1 drug alcohol 10604945 Together, our findings show that ethanol induction of Hsc70 requires a functional Sp1 binding site. SP1 drug alcohol 10604945 Additional proximal promoter elements may also play a role in determining whether an Sp1 containing promoter will respond to ethanol.

SP1 addiction withdrawal 9886677 It was concluded that the enhanced content of SP1 7 may also indicate the involvement of the SP system during opioid withdrawal in the rat. SP1 addiction withdrawal 9886677 The enhanced production of SP1 7 may reflect an increased release and/or metabolism of SP, which, in turn, counteracts the withdrawal. SP1 addiction sensitization 7682611 Behavioral sensitization to kainic acid (KA) in the mouse spinal cord appears to be mediated by the amino (N) terminus of substance P (SP), as potentiation of KA is sensitive to capsaicin, mimicked by SP1 7 but not SP5 11, and blocked by SP1 7 antagonists but not by neurokinin antagonists. SP1 drug opioid 7682611 As naloxone inhibits some effects of SP1 7, this study examines the role of opioid receptors in the mediation of KA induced sensitization by the N terminus of SP.

MMP2 drug amphetamine 17348864 In contrast, infusion of purified human MMP 2 into the NAc significantly potentiated the METH increased dopamine release. MMP2 drug amphetamine 17348864 The [(3)H]dopamine uptake into striatal synaptosomes was reduced in wild type mice after repeated METH treatment, but METH induced changes in [(3)H]dopamine uptake were significantly attenuated in MMP 2 ( / ) and MMP 9 ( / ) mice. MMP2 drug amphetamine 17348864 These results suggest that both MMP 2 and MMP 9 play a crucial role in METH induced behavioural sensitization and reward by regulating METH induced dopamine release and uptake in the NAc.

CBS drug cannabinoid 31690747 The CBs, Δ9 THC, cannabidiol, HU 210, and CP 55,940 caused alcohol like effects on craniofacial and brain development, phenocopying Shh mutations. CBS drug cannabinoid 31559334 In their natural form, CBs such as Δ9 tetrahydrocannabinolic acid and cannabidiolic acid are inactive at these receptors, while their decarboxylated forms (Δ9 tetrahydrocannabinol and cannabidiol, respectively) are potent ligands at CB receptors. CBS drug cannabinoid 31559334 Factors such as temperature and exposure time play important roles in the decarboxylation of phytocannabinoids, thereby generating pharmacologically active CBs, and these conditions may differ for each cannabis cultivar. CBS drug cannabinoid 31159897 Further, data encourage basic and clinical studies to determine how cannabis and cannabinoids (CBs) can affect mood and to investigate emerging CB based options as probable treatment approaches.

CBS drug cannabinoid 28583800 The organized, tightly regulated signaling relays engaged by the cannabinoid receptors (CBs) and their ligands, G proteins and other effectors, together constitute the endocannabinoid system (ECS). CBS addiction sensitization 26512068 On the other hand, we have found that AEA modulates the NTG induced changes, thus it influences the activation and central sensitization process in the trigeminal system, probably via CBs.

CBS drug cannabinoid 25143817 Synthetic cannabinoids (CBs) such as the JWH series have caused social problems concerning their abuse liability. CBS drug cannabinoid 25143817 In this study, three synthetic CBs with different binding affinities to the CB1 receptor (JWH 073, 081, and 210) and Δ(9) tetrahydrocannabinol (Δ(9) THC) were evaluated for their potential for psychological dependence.

CBS drug cannabinoid 22718500 Synthetic cannabinoids (CBs) [naphthalen 1 yl (1 pentylindol 3 yl) methanone (JWH 018) and naphthalen 1 yl (1 butylindol 3 yl) methanone (JWH 073)] are marketed, sold, and used as alternatives to cannabis. CBS drug cannabinoid 22718500 Synthetic CBs appear to have effects similar to those of Δ⁹ tetrahydrocannabinol (Δ⁹ THC), the drug primarily responsible for the behavioral effects of cannabis. CBS drug cannabinoid 22718500 The greater loss of sensitivity to Δ⁹ THC relative to CP 55,940 and JWH 018 suggests that differences in CB₁ receptor agonist efficacy are important in vivo and might underlie differences in the dependence liability and adverse effects of synthetic CBs versus cannabis.

CBS drug cannabinoid 17877812 Furthermore, based on the reported similarity in the mechanisms responsible for NC induced anxiety and depression related symptoms, as well as the contribution of brain cannabinoid (CB) receptors to these behavioral symptoms, the effects of anxiolytics and CB receptor ligands (CBs) against these behavioral symptoms were investigated. CBS drug alcohol 16332761 Crude cell extracts of a hydrolysate tolerant strain (TMB3000) converted both furfural and 5 hydroxymethyl furfural to the corresponding alcohol at a rate that was severalfold higher than the rate observed for cell extracts of a less tolerant strain (CBS 8066), thereby confirming that there is a correlation between the fermentation rate in a lignocellulosic hydrolysate and the bioconversion capacity of a strain. CBS addiction relapse 1957121 Duodenal ulcer relapse at 12 months after initial healing with CBS is significantly less than with H2 antagonist therapy. CBS drug nicotine 1957121 Ulcer healing with CBS is not influenced by smoking.

APOB drug opioid 21453194 ApoB/apoA I showed stronger correlation with the observed apo/lipoproteins than the HDL C. The logistic regression model showed that apoB/apoA I index (OR 89.1, 95% CI 1.3 5971.2) is more significant predictor in developing hypertriglyceridemia/low HDL profile than HDL C. Heroin addiction is associated with decreased plasma concentrations of HDL C, apoA I, apoB, and increased TGL concentrations. APOB addiction addiction 21453194 ApoB/apoA I showed stronger correlation with the observed apo/lipoproteins than the HDL C.

APOB addiction intoxication 16805392 During remission a general pattern of apoB containing LP was similar to the period of intoxication. APOB drug nicotine 16372134 These analyses revealed that R219K has a strong effect on apolipoprotein B (APOB) and LDL cholesterol (LDL C) among smokers (P = 0.000055 and P = 0.00059, respectively), but not among non smokers. APOB drug nicotine 16372134 These analyses revealed that R219K has a strong effect on apolipoprotein B (APOB) and LDL cholesterol (LDL C) among smokers (P = 0.000055 and P = 0.00059, respectively), but not among non smokers. APOB drug nicotine 16372134 Plasma APOB and LDL C, but not APOA1 and HDL C, were shown to be markedly elevated in smokers versus non smokers, affirming that smoking may selectively impact the former pathway. APOB drug alcohol 16272676 This study demonstrates the ability of TC, ApoB and LDL/HDL c (among lipid measures) and AST and GGT (among liver measures) in discriminating alcohol dependents from non dependent subjects. APOB drug alcohol 12963008 Alcohol ingestion along with a fat load increases the number (increased net apoB48 secretion) and reduces the size (reduced TAG/apoB48 ratio) of CM secreted into the mesenteric lymph duct. APOB drug alcohol 12916168 Under intoxication disturbances the individual apoB containing fractions were minimal as compared with the control, while at the initial stages of alcohol abolition their redistribution was noticed as reflecting the growth of the processes of cholesterol transportation from liver to peripheral tissues.

APOB addiction withdrawal 11981126 After withdrawal, concentrations of serum apoA I, LpA I, LpA I/A II, apoC III, LpC III non B, apoE, and LpE non B significantly decreased, whereas those of triglycerides and apoB increased; levels of cholesterol, LpC III:B, and LpB:E were not affected. APOB addiction withdrawal 11981126 Before withdrawal, no association between apoB level and apoE polymorphism was observed, whereas after abstinence, a borderline significant (p < or = 0.10) gradient of concentration across the three groups of subjects (epsilon2 carriers < epsilon3/epsilon3 < epsilon4 carriers) was noticed. APOB drug alcohol 11981126 Heavy alcohol consumption seems to alter the effect of apoE polymorphism on apoB levels, and further investigations are needed to clarify the mechanisms involved in this phenomenon: a defect in sialylation of apoE, formation of acetaldehyde adducts on apoB, or both. APOB addiction reward 11714857 In conclusion, this work, in addition to the reinforcement of the already known associations between APOB, APOE, and APOC3 genes and lipids, leads to new perspectives in the complex relationships among genes and environmental factors. APOB drug alcohol 1332524 To assess the effect of alcohol on these analytes, we determined the concentration of Lp(a), apolipoprotein A I, apolipoprotein B, total cholesterol, and high density lipoprotein cholesterol, and calculated low density lipoprotein cholesterol in serum of 12 patients meeting DSM III R criteria for alcohol dependence at the time of admission for treatment of alcohol withdrawal (before).

APOB drug nicotine 1521980 Adjustment for age, body mass index, smoking, alcohol consumption, stress and tension at work, shift work, noise exposure and educational level in multiple linear regression analysis showed significant effects of the CS2 index on systolic BP, diastolic BP, cholesterol, HDL cholesterol, LDL cholesterol, apolipoprotein A1, apolipoprotein B, the LDL cholesterol/apolipoprotein B and HDL cholesterol/apolipoprotein A1 ratios; there were no significant effects on the triglycerides. APOB drug alcohol 1930937 The plasma concentrations and chemical compositions of the apolipoprotein B containing lipoproteins (VLDL, IDL and LDL) were studied in 29 male alcoholic subjects at the end of a drinking period and in 17 healthy controls. APOB drug alcohol 1930937 These studies suggest that the alterations in all the apoB containing lipoproteins may contribute to the delayed progression of atherosclerosis observed in alcohol users. APOB addiction intoxication 1878009 Binge drinking produced a selective increase in low density lipoprotein (LDL) cholesterol and apolipoprotein B, and a depression in the fractional LCAT rate (% esterified/min). APOB addiction intoxication 1878009 By contrast, when this same average weekly dose is concentrated in a binge cycle, unfavorable alterations in lipoprotein composition (increases LDL cholesterol, increases apolipoprotein B) and metabolism (decreases LCAT activity) occur along with weight loss and depletion of body fat.

SULT2A1 drug opioid 30630161 The current study was designed to evaluate the effect of OT on withdrawal, craving and anxiety scores, cortisol and dehydroepiandrosterone sulphate (DHEAS) blood level in heroin dependent male patients. SULT2A1 addiction relapse 30630161 The current study was designed to evaluate the effect of OT on withdrawal, craving and anxiety scores, cortisol and dehydroepiandrosterone sulphate (DHEAS) blood level in heroin dependent male patients. SULT2A1 addiction withdrawal 30630161 The current study was designed to evaluate the effect of OT on withdrawal, craving and anxiety scores, cortisol and dehydroepiandrosterone sulphate (DHEAS) blood level in heroin dependent male patients. SULT2A1 drug opioid 30630161 Single dose of OT decreased the level of cortisol and improved the cortisol/DHEAS ratio in the heroin users during abstinence (p < 0.01). SULT2A1 drug opioid 29279713 Tramadol decreased the levels of serum cortisol and DHEAS hormones. SULT2A1 addiction dependence 28807679 pH Dependence and kinetics experiments indicated that the catalytic properties of zebrafish Sult2 family members in mediating the sulfation of 5α cyprinol were different from those of either zebrafish Sult3st4 or human SULT2A1. SULT2A1 drug alcohol 28807679 Collectively, these results imply that both Sult2st2 and Sult2st3 have evolved to sulfate specifically C27 bile alcohol, 5α cyprinol, in Cypriniform fish, whereas the enzymatic characteristics of zebrafish Sult3 members, particularly Sult3st4, correlated with those of human SULT2A1. SULT2A1 drug nicotine 23771199 Dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEAS) are neurosteroids that have been associated with mood measures as well as smoking status, and nicotine is associated with increased DHEA and DHEAS levels. SULT2A1 drug nicotine 23771199 Given the difficulties with mood experienced by smokers with PTSD, the purpose of the current study was to evaluate the association between negative affect and anxiety sensitivity with DHEA and DHEAS levels. SULT2A1 drug nicotine 23771199 Given that nicotine is known to elevate DHEA(S) levels, these results suggest that DHEAS may serve as a biomarker of the association between mood and nicotine among smokers. SULT2A1 drug nicotine 23771199 Implications for the results include (1) the use of DHEAS measurement across time and across quit attempts and (2) the potential for careful use of DHEA supplementation to facilitate abstinence during smoking cessation. SULT2A1 drug opioid 22946908 A systematic analysis using eleven known human SULTs revealed SULT1A3 and SULT2A1 as the major responsible SULTs for the sulfation of, respectively, pentazocine and buprenorphine; whereas three other SULTs, SULT1A1, SULT1A2, and SULT1C4, were capable of sulfating naloxone. SULT2A1 addiction dependence 22433179 To investigate whether long term exposure to the neurosteroid dehydroepiandrosterone sulfate (DHEAS) induces adaptive changes of GABA(A) receptors related to the development of tolerance and dependence. SULT2A1 drug benzodiazepine 22433179 We compared the parameters of [(3)H]DHEAS binding and the effects of DHEAS on [(3)H]flunitrazepam binding in the membranes of HEK 293 cells, nontransfected or stably transfected with recombinant α(1)β(2)γ(2S) GABA(A) receptors. SULT2A1 drug benzodiazepine 22433179 In HEK 293 cells expressing α(1)β(2)γ(2S) GABA(A) receptors, we investigated the effects of long term DHEAS treatment on the [(3)H]flunitrazepam and [(3)H]t butylbicycloorthobenzoate ([(3)H]TBOB) binding and on their modulation with GABA. SULT2A1 drug benzodiazepine 22433179 Exposure of cells to 100 μmol/l DHEAS for 48 h did not change the number or affinity of benzodiazepine and convulsive binding sites. SULT2A1 drug benzodiazepine 22433179 Long term DHEAS treatment failed to affect functional allosteric interactions between GABA(A) receptor binding sites, as evidenced by an unchanged ability of GABA to stimulate or to inhibit [(3)H]flunitrazepam and [(3)H]TBOB binding, respectively. SULT2A1 addiction dependence 22433179 The findings that prolonged DHEAS treatment does not produce changes in GABA(A) receptor expression and functional coupling, assumed to underlie the development of tolerance and dependence, might have importance in the long term therapy necessary for the observed beneficial effects of DHEAS. SULT2A1 addiction dependence 21839837 To further investigate the sulfation of bile acids and bile alcohols by the two Zebra danio SULT3 STs and the human SULT2A1, pH dependence and kinetics of the sulfation of bile acids/alcohols were analyzed. SULT2A1 drug alcohol 21839837 pH dependence experiments showed that the mechanisms underlying substrate recognition for the sulfation of lithocholic acid (a bile acid) and 5α petromyzonol (a bile alcohol) differed between the human SULT2A1 and the Zebra danio SULT3 ST2 and ST3. SULT2A1 addiction dependence 21839837 pH dependence experiments showed that the mechanisms underlying substrate recognition for the sulfation of lithocholic acid (a bile acid) and 5α petromyzonol (a bile alcohol) differed between the human SULT2A1 and the Zebra danio SULT3 ST2 and ST3. SULT2A1 addiction dependence 21598681 It had been shown that the blockade with dehydroepiandrosterone sulfate (DHEAS) affects enhanced aldosterone level in doses 1, 5 and 30 mg/kg without the dose dependence under multi repeated cold exposure. SULT2A1 drug opioid 21598681 These DHEAS effects are realized through micro opioid receptors. SULT2A1 drug opioid 21598681 The DHEAS (30 mg/kg) blocking effect was manifested too, but not through micro opioid receptors under acute cold exposure. SULT2A1 drug alcohol 17913324 Serum levels of basal cortisol and dehydroepiandrosterone sulphate (DHEAS) were measured three times, and cortisol and DHEAS response to dexamethasone twice during the early and late withdrawal periods in alcohol dependent males (n=30) and once in healthy control males (n=20). SULT2A1 addiction withdrawal 17913324 Serum levels of basal cortisol and dehydroepiandrosterone sulphate (DHEAS) were measured three times, and cortisol and DHEAS response to dexamethasone twice during the early and late withdrawal periods in alcohol dependent males (n=30) and once in healthy control males (n=20). SULT2A1 addiction withdrawal 17913324 The study revealed reduced basal DHEAS levels and reduced DHEAS response to dexamethasone in late withdrawal. SULT2A1 addiction withdrawal 17913324 While basal DHEAS levels were low in the high aggression group only in early withdrawal, it was reduced in the low aggression group during late withdrawal period. SULT2A1 drug alcohol 17511983 In the present report, we attempted to examine whether neurosteroids progesterone and dehydroepiandrosterone sulphate (DHEAS), which modulate gamma aminobutyric acid (GABA(A)) receptor function, affects development of tolerance to ethanol anxiolysis and withdrawal anxiety.

SULT2A1 drug alcohol 17511983 Rats on ethanol (6% v/v in nutritionally balanced liquid diet) for prolong period (10 days) were injected twice daily either with vehicle, progesterone (a precursor of allopregnanolone, positive GABA(A) receptor modulator), finasteride (5alpha reductase inhibitor) or DHEAS (negative GABA(A) receptor modulator). SULT2A1 drug alcohol 17511983 While progesterone significantly advanced the development of tolerance to ethanol anxiolysis and enhanced withdrawal anxiety, DHEAS and finasteride prevented such behavioral alterations. SULT2A1 addiction withdrawal 17511983 While progesterone significantly advanced the development of tolerance to ethanol anxiolysis and enhanced withdrawal anxiety, DHEAS and finasteride prevented such behavioral alterations.

RGS9 drug amphetamine 17493623 Moreover, treatment of ovariectomized female rats with the selective estrogen receptor beta agonist, diarylpropionitrile (1 mg/kg), for 2 weeks also facilitated amphetamine induced place preference behavior and selectively reduced nucleus accumbens shell RGS9 2 protein expression. RGS9 drug opioid 15870291 Behavioral testing on mutant adults revealed subtle sensorimotor deficits but, so far, supported neither the proposed status of Rgs4 as a schizophrenia susceptibility gene (by showing intact prepulse inhibition in the mutants) nor (unlike another member of the Rgs family, Rgs9) a role of Rgs4 in the acute or chronic response to opioids. RGS9 drug opioid 15199376 At 2 h after administering the acute opioid, RGS7 mRNA levels in the striatum plus those of RGS9 2 in the striatum and thalamus were increased, whereas RGS9 2 and RGS11 mRNA were reduced in the cortex. RGS9 drug opioid 15199376 At 2 days after commencing sustained morphine treatment, the levels of mRNA for RGS7, RGS9 2, RGS11, and Gbeta5 increased in most of the brain structures studied (striatum, thalamus, periaqueductal gray matter (PAG), and cortex). RGS9 drug opioid 15199376 In these morphine tolerant dependent mice, the greater changes were found for RGS9 2 in the thalamus (>500%) and PAG (>200%).

RGS9 drug opioid 15065220 In the present study, we examined the effects of morphine treatment (1 microM, 20 h) on DAMGO stimulated high affinity [35S]GTP gamma S binding and DAMGO mediated inhibition of forskolin stimulated cAMP accumulation in HN9.10 cells stably expressing the cloned rat mu opioid receptor, in the absence and presence of the RGS9 protein knock down condition (confirmed by Western blot analysis). RGS9 drug opioid 15065220 Morphine treatment increased the EC50 (6.2 fold) for DAMGO mediated inhibition of forskolin stimulated cAMP activity in control cells but not in cells treated with AS 114 to knock down RGS9. RGS9 drug opioid 15065220 These results provide additional evidence for involvement of RGS9 protein in modulating opioid signaling, which may contribute to the development of morphine tolerance and dependence.

RGS9 drug opioid 14595021 We show here that acute morphine administration increases expression of RGS9 2 in NAc and the other CNS regions, whereas chronic exposure decreases RGS9 2 levels.

PRTN3 addiction reward 14665979 Opiate reinforcement was evaluated under a progressive ratio (PR) schedule often used for psychostimulant self administration (termed 'PR 3 4' because the third response requirement was four lever presses) and three additional schedules that were modified to provide successively lower levels of difficulty by decreasing the steepness of response requirement progression (termed 'PR 9 4', 'PR 14 4', and 'PR 26 4' because a response requirement of four was reached with step numbers of 9, 14 and 26, respectively). PRTN3 drug opioid 14665979 With the exception of the PR 3 4 schedule, all of the schedules supported morphine self administration, and morphine self administration during initial exposure and reacquisition did not differ by more than 10%.

PER1 drug alcohol 27065929 These results extend our understanding of relationships between PER1 genotype, ELS, and problematic alcohol use, and serve as a cautionary tale on the importance of controlling for potential confounders in studies of moderation including gene × environment interactions.

NLRP3 drug opioid 28580822 Expressions of miR 223 in the miR 223, miR 223 + morphine, and miR 223 + NLRP3 + morphine were significantly higher than those in the chronic constriction injury, normal saline, and morphine groups. NLRP3 drug opioid 28580822 Compared with chronic constriction injury, normal saline and morphine groups, the mRNA and protein expressions of NLRP3, apoptosis associated speck like protein, Caspase 1, IL 1β, and IL 18 were significantly decreased in the miR 223 and miR 223 + morphine groups, while mRNA and protein expressions of NLRP3, apoptosis associated speck like protein, Caspase 1, IL 1β, and IL 18 were significantly increased in the NLRP3 and NLRP3 + morphine group. NLRP3 drug opioid 28580822 Conclusion Our study provides strong evidence that miR 223 could suppress the activities of NLRP3 inflammasomes (NLRP3, apoptosis associated speck like protein, and Caspase 1) to relieve morphine analgesic tolerance in rats by down regulating NLRP3. NLRP3 drug cocaine 28057531 To empirically test these assumptions, we evaluated the (neuro)psychological trait and the functional organization of the resting state brain networks associated with the NAcs in 18 former cocaine abusers (FCAs), while being in drug abstinence since 5 months. NLRP3 drug cocaine 28057531 In the 8 FCAs who relapsed into cocaine use after 3 months, the level of functional connectivity between the NAcs and dPFC was lower than the functional connectivity estimated in the group of patients that did not relapsed. NLRP3 drug opioid 27247388 Morphine paradoxically prolongs neuropathic pain in rats by amplifying spinal NLRP3 inflammasome activation. NLRP3 drug opioid 27247388 Using pharmacologic and genetic approaches, we discovered that the initiation and maintenance of this multimonth prolongation of neuropathic pain was mediated by a previously unidentified mechanism for spinal cord and pain namely, morphine induced spinal NOD like receptor protein 3 (NLRP3) inflammasomes and associated release of interleukin 1β (IL 1β). NLRP3 addiction sensitization 26937141 SFA palmitic acid (PA) directly activated NLRP3 inflammasome and increased sensitization to LPS induced inflammasome activation in hepatocytes. NLRP3 addiction sensitization 26937141 Furthermore, a high fat diet increased but PUFA enriched diet decreased sensitization to LPS induced hepatic NLRP3 inflammasome activation in vivo. NLRP3 drug alcohol 26937141 Hepatic NLRP3 inflammasome activation played an important role in the development of non alcoholic fatty liver disease. NLRP3 drug alcohol 25582105 It was reported that alcohol consumption activated the NLRP3 inflammasome in Kupffer cells, leading to mature interleukin (IL) 1β release in alcoholic liver injury; however, how IL 1β promotes liver injury remains unclear. NLRP3 drug alcohol 25582105 Increased gene and protein expression of mature IL 1β correlated with elevated expression of the NLRP3 inflammasome components NLRP3, ASC, and cleaved caspase 1 in Kupffer cells from ethanol exposed wild type mice. NLRP3 drug alcohol 25582105 NLRP3 deficiency led to the attenuation of alcoholic steatosis, similarly as Kupffer cell depletion, almost without hepatic NKT cells. NLRP3 drug alcohol 25582105 After alcohol exposure Kupffer cell derived IL 1β triggered by NLRP3 activation, recruits and activates hepatic iNKT cells, subsequently promoting liver inflammation and neutrophil infiltration, and inducing alcoholic liver injury. NLRP3 drug opioid 23352192 Involvement of the NLRP3 inflammasome in the modulation of an LPS induced inflammatory response during morphine tolerance. NLRP3 drug opioid 23352192 We have explored the effects of lipopolysaccharide (LPS) during morphine tolerance on expression of the NLRP3 inflammasome and related inflammatory genes. NLRP3 drug opioid 23352192 In response to LPS, expression of 27 genes, including NLRP3, TNF α, IL 1β, and IL 6, was significantly increased, and expression of 3 genes was significantly decreased in both the morphine tolerant and placebo control groups compared to the saline treated animals. NLRP3 drug opioid 23352192 However, there was only a 2.7 fold increase in NLRP3 expression in response to LPS in the morphine tolerant rats compared to a 4.5 fold increase in the placebo control animals. NLRP3 drug opioid 23352192 Our data indicate that, in the morphine tolerant state, LPS induced expression of NLRP3 is suppressed and cytokine/chemokine expression is inhibited, which may be one of the mechanisms involved in morphine induced immunosuppression. NGFR addiction intoxication 31693929 This study investigated the effect of binge like MA dosing (4 x 4 mg/kg, s.c., 2 h (h) apart) at a range of different time points (from 2 h to 7 days after treatment) on brain derived neurotrophic factor (BDNF) levels and its receptors, TrkB and p75NTR. NGFR drug opioid 31173919 Conversely, the lack of extinction training (sham extinction) upregulated genes associated with kinases (Camk2g), neurotrophins (Ngfr), synaptic connectivity factors (Ephb2), glutamate neurotransmission (Grm8) and opioid receptors (μ1, Δ1). NGFR drug alcohol 31156431 The BDNF signaling mechanism is complex and depends on two receptor systems, TrkB and p75NTR, which appear to have opposite effects on alcohol seeking behavior in animal models. NGFR addiction relapse 31156431 The BDNF signaling mechanism is complex and depends on two receptor systems, TrkB and p75NTR, which appear to have opposite effects on alcohol seeking behavior in animal models. NGFR drug cannabinoid 30339727 Treatment of CD271 expressing melanoma subpopulations with RNA interference and small molecule inhibitors to CD271 reduced the development of MEKi resistance, while clinically applicable autophagy modulatory agents including Δ9 tetrahydrocannabinol and Vps34 reduced survival of MEKi resistant melanoma cells. NGFR drug alcohol 29520063 ProBDNF/p75NTR/sortilin pathway is activated in peripheral blood of patients with alcohol dependence. NGFR addiction dependence 29520063 ProBDNF/p75NTR/sortilin pathway is activated in peripheral blood of patients with alcohol dependence. NGFR drug alcohol 29520063 We found that the protein levels of proBDNF and p75NTR were increased, but not the sortilin protein level; while the TrkB protein level was decreased in the alcohol dependence patients compared with healthy controls. NGFR addiction dependence 29520063 We found that the protein levels of proBDNF and p75NTR were increased, but not the sortilin protein level; while the TrkB protein level was decreased in the alcohol dependence patients compared with healthy controls. NGFR drug alcohol 29520063 The levels of mBDNF and TrkB were negatively correlated with the average amount of daily ethanol consumption, and the levels of proBDNF, p75NTR and sortilin were positively correlated with the average amount of ethanol consumption per day. NGFR drug alcohol 29520063 The balance between the proBDNF/p75NTR and mBDNF/TrkB signalling pathways appeared dysregulated in alcohol dependence. NGFR addiction dependence 29520063 The balance between the proBDNF/p75NTR and mBDNF/TrkB signalling pathways appeared dysregulated in alcohol dependence. NGFR drug amphetamine 29165617 Selective Activation of Striatal NGF TrkA/p75NTR/MAPK Intracellular Signaling in Rats That Show Suppression of Methamphetamine Intake 30 Days following Drug Abstinence. NGFR drug amphetamine 29165617 These findings support the notion that animals with distinct phenotypes for methamphetamine intake in the presence of adverse consequences also display differential changes in an intracellular signaling cascade activated by nerve growth factor TrkA/p75NTR interactions. NGFR drug alcohol 28032807 Reverse transcription PCR (RT PCR) was performed to measure mRNA levels for BDNF, TrkB, P75NTR, and sortilin in the prefrontal cortex, hippocampus, and dorsal striatum of Kunming mice after chronic alcohol exposure. NGFR drug alcohol 27683907 We report that intermittent access to 20% alcohol in a two bottle choice paradigm that models excessive alcohol drinking produces a mobilization of DLS p75 neurotrophin receptor (p75NTR), whose activities oppose those of the Trk receptors, including TrkB. NGFR drug alcohol 27683907 Furthermore, short hairpin RNA (shRNA) mediated knockdown of the p75NTR gene in the DLS, as well as intra DLS infusion or systemic administration of the p75NTR modulator, LM11A 31, significantly reduced binge drinking of alcohol. NGFR addiction intoxication 27683907 Furthermore, short hairpin RNA (shRNA) mediated knockdown of the p75NTR gene in the DLS, as well as intra DLS infusion or systemic administration of the p75NTR modulator, LM11A 31, significantly reduced binge drinking of alcohol. NGFR drug alcohol 27683907 Together, our results suggest that excessive alcohol consumption produces a change in BDNF signaling in the DLS, which is mediated by the recruitment of p75NTR. NGFR drug alcohol 27683907 Our data also imply that modulators of p75NTR signaling could be developed as medications for alcohol abuse disorders. NGFR drug alcohol 27683907 Here, we show that a history of excessive alcohol intake produces neuroadaptations in the DLS that preclude BDNF's ability to gate alcohol self administration in rats by the recruitment of the low affinity neurotrophin receptor, p75NTR, whose activities opposes those of the Trk receptors. NGFR drug alcohol 27683907 Finally, we show that the administration of the p75NTR modulator, LM11A 31, significantly reduces excessive alcohol intake suggesting that the drug may be developed as a new treatment for alcohol abuse disorders. NGFR drug opioid 19114089 Because neurotrophins universally bind the p75 neurotrophin receptor (p75NTR), we investigated whether the activity of this receptor is involved in the development of opioid analgesic tolerance and physical dependence. NGFR addiction dependence 19114089 Because neurotrophins universally bind the p75 neurotrophin receptor (p75NTR), we investigated whether the activity of this receptor is involved in the development of opioid analgesic tolerance and physical dependence. NGFR drug opioid 19114089 However, the loss of morphine analgesia was not observed in p75NTR / mice. NGFR addiction withdrawal 19114089 This challenge precipitated a robust withdrawal syndrome that was comparable in wild type mice and p75NTR / mice. NGFR drug opioid 19114089 The findings suggest that p75NTR activity plays a critical role in the development of opioid analgesic tolerance but not in the induction or the expression of opioid physical dependence. NGFR addiction dependence 19114089 The findings suggest that p75NTR activity plays a critical role in the development of opioid analgesic tolerance but not in the induction or the expression of opioid physical dependence. NGFR drug alcohol 15246696 Alterations of cerebellar mRNA specific for BDNF, p75NTR, and TrkB receptor isoforms occur within hours of ethanol administration to 4 day old rat pups. IFITM1 drug nicotine 23901338 The multivariate model showed that anemia (AOR: 19.8, 95% CI: 5.6 35.5), positive sputum smear (AOR: 13.4, 95% CI: 6.8 33.6), smoking (AOR: 12.9, 95% CI: 3.9 27.3), drug hepatitis (AOR: 12.3, 95% CI: 6.7 24.7), diabetes mellitus (AOR: 9.7, 95% CI: 2.9 32.0), drug use (AOR: 7.8, 95% CI: 2.4 25.5), and history of previous TB (AOR: 6.8, 95% CI: 2.2 21.3) were major risk factors for death in TB patients. IFITM1 drug nicotine 22189160 Youths were 18 times more likely to be current smokers (95% CI = 11.9 27.2, p < 0.001) if they endorsed any AUTOS item. IFITM1 drug nicotine 19360537 Compared with youth of European background (11.4%; 95% CI 6.7 15.1), Indigenous (23.0%; 95% CI 21.0 25.0), and Mixed ethnicity (23%; 95% CI 18.9 27.1) youth had higher prevalence of current smoking. GPR55 drug cannabinoid 31437433 Strikingly, this reduction in both cocaine self administration and BSR was blocked by AM630 (a cannabinoid CB2 receptor antagonist), WAY100135 (a 5 HT1A receptor antagonist), or capsazepine (a TRPV1 channel blocker), but not by AM251 (a CB1 receptor antagonist), CID16020046 (a GPR55 antagonist), or naloxone (an opioid receptor antagonist), suggesting the involvement of CB2, 5 HT1A, and TRPV1 receptors in CBD action.

GPR55 drug cannabinoid 30767756 Recent studies have suggested that in addition to CB1 and CB2, there are non CB1 and non CB2 cannabinoid related orphan GPCRs including GPR18, GPR55, and GPR119. GPR55 drug cannabinoid 30391203 PEA targets not only the peroxisome proliferator activated receptor alpha (PPAR α), but also the endocannabinoid system, binding the G protein coupled receptor 55, a non CB1/CB2 cannabinoid receptor, and also the CB1/CB2 receptors, although with a weak affinity. GPR55 drug alcohol 29957399 Ethanol induced modulation of GPR55 expression in human monocyte derived dendritic cells is accompanied by H4K12 acetylation. GPR55 drug alcohol 29957399 Our lab has shown that the G protein coupled receptor (GPR55), a novel cannabinoid receptor, is upregulated in binge drinkers and in cells treated acutely with ethanol. GPR55 drug cannabinoid 29957399 Our lab has shown that the G protein coupled receptor (GPR55), a novel cannabinoid receptor, is upregulated in binge drinkers and in cells treated acutely with ethanol. GPR55 addiction intoxication 29957399 Our lab has shown that the G protein coupled receptor (GPR55), a novel cannabinoid receptor, is upregulated in binge drinkers and in cells treated acutely with ethanol. GPR55 drug alcohol 29957399 However, the regulatory mechanism of GPR55 within the immune system under the influence of ethanol is poorly understood. GPR55 drug alcohol 29957399 Since changes in histone modifications might lead to changes in gene expression, we hypothesize that the mechanism of ethanol induced upregulation of GPR55 is linked to epigenetic changes on histone proteins. GPR55 drug alcohol 29957399 Taking into account previous findings from our lab, the goal of the present study was to determine whether there is any relevant association between histone hyperacetylation and the regulation of the novel cannabinoid receptor GPR55 in monocyte derived dendritic cells (MDDCs) of human origin treated acutely with ethanol. GPR55 drug cannabinoid 29957399 Taking into account previous findings from our lab, the goal of the present study was to determine whether there is any relevant association between histone hyperacetylation and the regulation of the novel cannabinoid receptor GPR55 in monocyte derived dendritic cells (MDDCs) of human origin treated acutely with ethanol. GPR55 drug alcohol 29957399 The cells were treated with ethanol for 24 h, harvested, fixed, and stained with antibodies against GPR55. GPR55 drug alcohol 29957399 As expected, based on previous findings, confocal microscopy showed that ethanol exposure increases GPR55 expression. GPR55 drug alcohol 29957399 In order to demonstrate the correlation between histone acetylation and GPR55 expression regulation, the cells were treated with ethanol, harvested, and then the chromatin was extracted and fractionated for chromatin immunoprecipitation (ChIP) assay, followed by real time qPCR for the analysis of DNA fragments. GPR55 drug alcohol 29957399 The results showed an enrichment of the histone modification H4K12ac in the GPR55 gene of MDDCs treated with ethanol. GPR55 drug alcohol 29957399 In conjunction, these results indicate that in the presence of ethanol, the upregulation of GPR55 expression is accompanied by H4K12 acetylation, which might have a significant effect in the ability of this innate immune system's cells to cope with cellular stress induced by ethanol. GPR55 drug alcohol 29957399 However, the causality of ethanol regulation of H4K12ac in GPR55 expression changes still lacks further elucidation; therefore, additional experimental approaches to confirm a significant causality between H4K12 acetylation and ethanol regulation of GPR55 are currently undergoing in our lab. GPR55 drug cannabinoid 29773016 It has wide spectrum of action because it acts through endocannabinoid receptors; CB1 and CB2 and it also acts on other receptors, such as GPR18, GPR55, GPR 119, 5HT1A, and TRPV2. GPR55 drug cannabinoid 28861501 Palmitoylethanolamide Modulates GPR55 Receptor Signaling in the Ventral Hippocampus to Regulate Mesolimbic Dopamine Activity, Social Interaction, and Memory Processing. GPR55 drug cannabinoid 28861501 Introduction: The GPR55 receptor has been identified as an atypical cannabinoid receptor and is implicated in various physiological processes. GPR55 drug cannabinoid 28861501 Materials and Methods: Using a combination of in vivo electrophysiology and behavioral pharmacological assays in rats, we tested whether intra vHipp activation of GPR55 receptor transmission with the fatty acid amide, palmitoylethanolamide (PEA), a lipid neuromodulator with agonist actions at the GPR55 receptor, may modulate mesolimbic dopaminergic activity states. GPR55 addiction reward 28861501 Furthermore, while PEA induced activation of GPR55 transmission had no effects on opiate related reward related memory formation, we observed strong disruptions in social interaction and recognition memory, spatial location memory, and context independent associative fear memory formation. GPR55 drug cannabinoid 28861501 Conclusions: The present results add to a growing body of evidence demonstrating important functional roles for GPR55 signaling in cannabinoid related neuronal and behavioral phenomena and underscore the potential for GPR55 signaling in the mediation of cannabinoid related effects independently of the CB1/CB2 receptor systems. GPR55 drug cannabinoid 28428628 The G protein coupled receptor GPR55 has been postulated to serve as a novel cannabinoid receptor. GPR55 drug cannabinoid 28194850 Gene expression analyses of tyrosine hydroxylase in ventral tegmental area and μ opioid (Oprm1), cannabinoid (CB1 r and CB2 r) and GPR55 receptors in nucleus accumbens (NAcc) were carried out by real time polymerase chain reaction. GPR55 drug opioid 28194850 Gene expression analyses of tyrosine hydroxylase in ventral tegmental area and μ opioid (Oprm1), cannabinoid (CB1 r and CB2 r) and GPR55 receptors in nucleus accumbens (NAcc) were carried out by real time polymerase chain reaction. GPR55 drug cannabinoid 26971034 Previous studies show that some non CB1/non CB2 effects of cannabinoids are mediated through G protein coupled receptor 55 (GPR55). GPR55 drug cannabinoid 26971034 Previous studies show that some non CB1/non CB2 effects of cannabinoids are mediated through G protein coupled receptor 55 (GPR55).

GPR55 drug alcohol 24060590 Therefore, we studied the expression of CNR1 and CNR2, and the novel cannabinoid G protein coupled receptor (GPCR) 55 (GPR55) in human monocyte derived dendritic cells (MDDCs) from alcohol users. GPR55 drug cannabinoid 24060590 Therefore, we studied the expression of CNR1 and CNR2, and the novel cannabinoid G protein coupled receptor (GPCR) 55 (GPR55) in human monocyte derived dendritic cells (MDDCs) from alcohol users. GPR55 drug alcohol 24060590 MDDCs from alcohol users show significantly higher levels of CNR2 and GPR55 compared to MDDCs from non users. GPR55 drug alcohol 24060590 Our results provide insights into alcohol mechanisms of DC regulation and show, for the first time, that alcohol is inducing CNR2 and GPR55 in human DCs. GPR55 drug cannabinoid 23643692 CB1 or CB2 receptor expression was not altered in any of the regions examined, however VPA exposed rats exhibited reduced PPARα and GPR55 expression in the frontal cortex and PPARγ and GPR55 expression in the hippocampus, additional receptor targets of the endocannabinoids. GPR55 drug cannabinoid 22820167 GPR55 and GPR35 and their relationship to cannabinoid and lysophospholipid receptors. GPR55 drug cannabinoid 22820167 This review presents a summary of what is known about the G protein coupled receptors GPR35 and GPR55 and their potential characterization as lysophospholipid or cannabinoid receptors, respectively. GPR55 drug cannabinoid 22820167 Similarly, GPR55 has been suggested to be a cannabinoid receptor, but is quite clearly also a receptor for lysophosphatidylinositol. GPR55 drug cannabinoid 22141465 Although similar alterations in FAAH mRNA were evident following either continuous or intermittent EtOH exposure, alterations in MAGL and cannabinoid receptor related mRNA (e.g., CB(1) , CB(2) , GPR55) were more pronounced following intermittent exposure. GPR55 drug cannabinoid 21907912 The G protein coupled receptor 55 (GPR55) was recently proposed as a novel component of this system; however, its classification as a cannabinoid receptor has been significantly hampered by its complex pharmacology, signaling, and cellular function. GPR55 drug cannabinoid 21907912 The G protein coupled receptor 55 (GPR55) was recently proposed as a novel component of this system; however, its classification as a cannabinoid receptor has been significantly hampered by its complex pharmacology, signaling, and cellular function. GPR55 drug cannabinoid 21907912 GPR55 is phylogenetically distinct from the traditional cannabinoid receptors, but in some experimental paradigms, it is activated by endocannabinoids, phytocannabinoids, and synthetic cannabinoid ligands. GPR55 drug cannabinoid 19723626 Atypical responsiveness of the orphan receptor GPR55 to cannabinoid ligands. GPR55 drug cannabinoid 19723626 Whether the orphan G protein coupled receptor GPR55 is also a cannabinoid receptor remains unclear as a result of conflicting pharmacological studies. GPR55 drug cannabinoid 19723626 GPR55 has been reported to be activated by exogenous and endogenous cannabinoid compounds but surprisingly also by the endogenous non cannabinoid mediator lysophosphatidylinositol (LPI). GPR55 drug cannabinoid 19723626 We examined the effects of a representative panel of cannabinoid ligands and LPI on GPR55 using a beta arrestin green fluorescent protein biosensor as a direct readout of agonist mediated receptor activation. GPR55 drug cannabinoid 19723626 Our data demonstrate that AM251 and SR141716A (rimonabant), which are cannabinoid antagonists, and the lipid LPI, which is not a cannabinoid receptor ligand, are GPR55 agonists. GPR55 drug cannabinoid 19723626 Conversely, the potent synthetic cannabinoid agonist CP55,940 acts as a GPR55 antagonist/partial agonist. GPR55 drug cannabinoid 19723626 CP55,940 blocks GPR55 internalization, the formation of beta arrestin GPR55 complexes, and the phosphorylation of ERK1/2; CP55,940 produces only a slight amount of protein kinase CbetaII membrane recruitment but does not stimulate membrane remodeling like LPI, AM251, or rimonabant. GPR55 drug cannabinoid 19723626 Our studies provide a paradigm for measuring the responsiveness of GPR55 to a variety of ligand scaffolds comprising cannabinoid and novel compounds and suggest that at best GPR55 is an atypical cannabinoid responder. GPR55 drug cannabinoid 19723626 The activation of GPR55 by rimonabant may be responsible for some of the off target effects that led to its removal as a potential obesity therapy. GPR55 drug cannabinoid 19335651 Gene association studies are presented for (a) genes posited to have specific influences on cannabis use disorders: CNR1, CB2, FAAH, MGLL, TRPV1 and GPR55 and (b) genes from various neurotransmitter systems that are likely to exert a non specific influence on risk of cannabis use disorders, e.g. GPR55 drug cannabinoid 19306092 The cannabinoid receptor family currently includes two cloned metabotropic receptors: CB1, CB2 and possibly GPR55 which are distributed widely across many key loci in pain modulating pathways, including the peripheral terminals of primary afferents. GPR55 drug cannabinoid 17704827 The novel endocannabinoid receptor GPR55 is activated by atypical cannabinoids but does not mediate their vasodilator effects. GPR55 drug cannabinoid 17704827 Recent reports suggest GPR55 is an atypical cannabinoid receptor, making it a candidate for the vasodilator 'CBx' receptor. GPR55 drug cannabinoid 17704827 The purpose of the present study was to test the hypothesis that human recombinant GPR55 is activated by atypical cannabinoids and mediates vasodilator responses to these agents. GPR55 drug cannabinoid 17704827 In GPR55 deficient and wild type littermate control mice, in vivo blood pressure measurement and isolated resistance artery myography were used to determine GPR55 dependence of atypical cannabinoid induced haemodynamic and vasodilator responses. GPR55 addiction dependence 17704827 In GPR55 deficient and wild type littermate control mice, in vivo blood pressure measurement and isolated resistance artery myography were used to determine GPR55 dependence of atypical cannabinoid induced haemodynamic and vasodilator responses. GPR55 drug cannabinoid 17704827 Atypical cannabinoids O 1602 and abnormal cannabidiol both stimulated GPR55 dependent GTPgammaS activity (EC50 approximately 2 nM), whereas the CB1 and CB2 selective agonist WIN 55,212 2 showed no effect in GPR55 expressing HEK293T cell membranes. GPR55 drug cannabinoid 17704827 These results demonstrate that while GPR55 is activated by atypical cannabinoids, it does not appear to mediate the vasodilator effects of these agents. ECD addiction dependence 25650831 Cell death caused by the amphipathic helix had features similar to HR, such as SGT1 dependence. ECD drug psychedelics 23775255 After behavioral testing was complete, monoamine and associated metabolite levels in discrete brain regions were quantified using high performance liquid chromatography coupled to electrochemical detection (HPLC ECD) to determine if adolescent animals displayed a different neurochemical profile than did adult animals after being exposed to subcutaneous low doses of MDMA. ECD drug nicotine 20640803 For comparison, we also built the ECD models of alpha4beta2, and alpha7 subunits of human nACHRs which are neurochemical targets for cessation of smoking. ECD drug amphetamine 20370784 Methamphetamine has been present in arrest related death cases in which an electronic control device (ECD) was used.

ECD addiction dependence 16752921 Besides becoming resistant to detergent inhibition, the soluble human E NTPDase 8 ECD displays greater activity with Ca nucleotide substrates, an increased affinity for ATP, different pH dependence, and a decreased sensitivity to azide inhibition when compared to the membrane bound enzyme. ECD drug alcohol 16480820 In order to further characterize the different effects of drugs induced AA release in the striatum and NAc, in the present study, we investigated the effect of ethanol, morphine, methamphetamine, nicotine induced AA release in these two nuclei using microdialysis coupled to high performance liquid chromatography with electrochemical detection (HPLC ECD).

RNASE1 drug amphetamine 31660086 Different roles of Rac1 in the acquisition and extinction of methamphetamine associated contextual memory in the nucleus accumbens. RNASE1 drug amphetamine 31660086 Here, we explored whether Rac1 in the NAc mediates METH associated contextual memory and spine remodelling. RNASE1 drug amphetamine 31660086 Methods: Pharmacological and genetic manipulations of Rac1 were used to investigate its role during the acquisition, reconsolidation and extinction of METH associated contextual memory. RNASE1 drug amphetamine 31660086 Results: Using viral mediated gene transfer, we demonstrated that decreased Rac1 activity was required for the acquisition of METH associated contextual memory and the METH induced increase in thin spine density, whereas increased Rac1 signalling was important for the extinction of METH associated contextual memory and the related elimination of thin spines. RNASE1 drug amphetamine 31660086 Interestingly, Rac1 was responsible for METH induced spine plasticity in D1 MSNs but not in D2 MSNs. RNASE1 drug amphetamine 31660086 Additionally, we found that microinjection of a Rac1 inhibitor or activator into the NAc was not sufficient to disrupt reconsolidation, and the pharmacological activation of Rac1 in the NAc facilitated the extinction of METH associated contextual memory. RNASE1 drug amphetamine 31660086 Regarding cognitive memory, decreased Rac1 activity improved the METH induced impairment in object recognition memory. RNASE1 drug amphetamine 31660086 Conclusion: Our findings indicate that Rac1 plays opposing roles in the acquisition and extinction of METH associated contextual memory and reveal the cell specific role of Rac1 in METH associated spine remodelling, suggesting that Rac1 is a potential therapeutic target for reducing relapse in METH addiction and remediating METH induced recognition memory impairment.

RNASE1 drug alcohol 31558618 Here we investigate the role of Rac1 and its downstream target, the actin severing protein cofilin, in alcohol consumption preference. RNASE1 drug alcohol 31558618 We show that these two regulators of actin dynamics can alter male experience dependent alcohol preference in a bidirectional manner: expressing either activated Rac1 or dominant negative cofilin in the mushroom bodies (MBs) abolishes experience dependent alcohol preference. RNASE1 drug alcohol 31558618 Conversely, dominant negative Rac1 or activated cofilin MB expression lead to faster acquisition of alcohol preference. RNASE1 drug alcohol 31558618 Our data show that Rac1 and cofilin activity are key to determining the rate of acquisition of alcohol preference, revealing a critical role of actin dynamics regulation in the development of voluntary self administration in Drosophila SIGNIFICANCE STATEMENT The risks for developing an alcohol use disorder (AUD) are strongly determined by genetic factors.

RNASE1 drug amphetamine 31060803 However, how dopamine D1 and D2 receptors (D1Rs and D2Rs, respectively) as well as downstream signaling pathways, such as those involving Rac1 and Cdc42, modulate METH induced behavioral and structural plasticity is largely unknown. RNASE1 drug amphetamine 31060803 Using NAc conditional D1R and D2R deletion mice, Rac1 and Cdc42 mutant viruses, and a series of behavioral and morphological methods, we assessed the effects of D1Rs and D2Rs on Rac1 and Cdc42 in modulating METH induced behavioral and structural plasticity in the NAc. RNASE1 drug amphetamine 31060803 Interestingly, Rac1 and Cdc42 signaling were oppositely modulated by METH, and suppression of Rac1 signaling and activation of Cdc42 signaling were crucial to METH induced conditioned place preference and structural plasticity but not to locomotor activation. RNASE1 drug amphetamine 31060803 D1Rs activated Rac1 and Cdc42 signaling, while D2Rs inhibited Rac1 signaling but activated Cdc42 signaling to mediate METH induced conditioned place preference and structural plasticity but not locomotor activation. RNASE1 drug amphetamine 31060803 In addition, NAc D1R deletion aggravated METH withdrawal induced spatial learning and memory impairment by suppressing Rac1 signaling but not Cdc42 signaling, while NAc D2R deletion aggravated METH withdrawal induced anxiety without affecting Rac1 or Cdc42 signaling.

RNASE1 drug cocaine 25957559 Dishevelled 2 regulates cocaine induced structural plasticity and Rac1 activity in the nucleus accumbens. RNASE1 drug cocaine 25957559 In this study we examined whether isoforms of Dishevelled, a key hub protein of multiple branches of Wnt signaling, including Rac1, are regulated in the NAc by chronic cocaine, and whether these Dishevelled isoforms control Rac1 activity in this brain region in vivo. RNASE1 drug cocaine 25957559 We found that chronic cocaine administration decreased expression of Dishevelled 2, and several other Wnt signaling components, in the NAc, and that overexpression of Dishevelled 2, but not Dishevelled 1, conversely upregulated Rac1 activity and prevented the cocaine induction of dendritic spines on NAc MSNs. RNASE1 drug cocaine 25957559 We posit that the cocaine induced downregulation of Dishevelled 2 in the NAc is an upstream regulator of Rac1 activity and plays an important role in the dynamic structural plasticity of NAc MSNs seen in response to chronic cocaine exposure. RNASE1 drug cocaine 25595128 Cocaine activates Rac1 to control structural and behavioral plasticity in caudate putamen. RNASE1 drug cocaine 25595128 In this study, we investigated the role of Rac1 in cocaine induced dendritic and behavioral plasticity in the CPu. RNASE1 drug cocaine 25595128 We found that Rac1 activation was reduced in the NAc but increased in the CPu following repeated cocaine treatment. RNASE1 drug cocaine 25595128 Inhibition of Rac1 activity by a Rac1 specific inhibitor NSC23766, overexpression of a dominant negative mutant of Rac1 (T17N Rac1) or local knockout of Rac1 attenuated the cocaine induced increase in dendrites and spine density in the CPu, whereas overexpression of a constitutively active Rac1 exert the opposite effect. RNASE1 drug cocaine 25595128 Downregulation of Rac1 activity likewise attenuates behavioral reward responses to cocaine exposure, with activation of Rac1 producing the opposite effect. RNASE1 addiction reward 25595128 Downregulation of Rac1 activity likewise attenuates behavioral reward responses to cocaine exposure, with activation of Rac1 producing the opposite effect. RNASE1 drug cocaine 25595128 Thus, Rac1 signaling is differentially regulated in the NAc and CPu after repeated cocaine treatment, and induction of Rac1 activation in the CPu is important for cocaine exposure induced dendritic remodeling and behavioral plasticity. RNASE1 drug alcohol 25257290 Alcohol rapidly decreased GTP bound Rac1 but not RhoA during the drop in TER. RNASE1 drug cocaine 23628212 These studies confirmed the classical hypothesis of movement control and reward seeking behavior through direct versus indirect pathway MSNs; illuminated a selective role for TANs in cocaine reward; dissected the roles of glutamatergic and dopaminergic inputs to striatum in reward; and highlighted a role for striatal signaling molecules including an adrenergic G protein coupled receptor in reward and the rho GTPase Rac1 in cocaine reward and cocaine induced structural plasticity. RNASE1 addiction relapse 23628212 These studies confirmed the classical hypothesis of movement control and reward seeking behavior through direct versus indirect pathway MSNs; illuminated a selective role for TANs in cocaine reward; dissected the roles of glutamatergic and dopaminergic inputs to striatum in reward; and highlighted a role for striatal signaling molecules including an adrenergic G protein coupled receptor in reward and the rho GTPase Rac1 in cocaine reward and cocaine induced structural plasticity. RNASE1 addiction reward 23628212 These studies confirmed the classical hypothesis of movement control and reward seeking behavior through direct versus indirect pathway MSNs; illuminated a selective role for TANs in cocaine reward; dissected the roles of glutamatergic and dopaminergic inputs to striatum in reward; and highlighted a role for striatal signaling molecules including an adrenergic G protein coupled receptor in reward and the rho GTPase Rac1 in cocaine reward and cocaine induced structural plasticity. RNASE1 addiction aversion 23564082 The small GTPase RhoA, but not Rac1, is essential for conditioned aversive memory formation through regulation of actin rearrangements in rat dorsal hippocampus. RNASE1 drug alcohol 23223291 Adult neuronal Arf6 controls ethanol induced behavior with Arfaptin downstream of Rac1 and RhoGAP18B. RNASE1 drug alcohol 23223291 We also find that the Drosophila Arfaptin protein directly binds to the activated forms of Arf6 and Rac1 GTPases, and mutants in Arfaptin also display ethanol sensitivity. RNASE1 drug alcohol 23223291 Arf6 acts downstream of Rac1 and Arfaptin to regulate ethanol induced behaviors, and we thus demonstrate that this conserved Rac1/Arfaptin/Arf6 pathway is a major mediator of ethanol induced behavioral responses. RNASE1 drug cocaine 18952886 Cocaine induced reactive oxygen species (ROS) production was associated with significant increases (approximately 2 fold) in the protein expressions of Nox2 (an isoform of NADPH oxidase) and its regulatory subunits: p22(phox), p67(phox), p47(phox), p40(phox), and Rac1, and in p47(phox) phosphorylation as detected by immunoblotting (all p < 0.03). RNASE1 drug alcohol 17018286 Indeed, expression of constitutively active forms of Rho1 or Rac1 in adult flies results in ethanol resistance similar to that observed in whir mutants. RNASE1 drug opioid 16472257 Somatostatin acting via G(i)1 coupled sstr3 receptor, DPDPE ([D Pen2,D Pen5]enkephalin; where Pen is penicillamine) acting via G(i)2 coupled delta opioid receptors, and cyclopentyl adenosine acting via G(i)3 coupled adenosine A1 receptors preferentially activated PI3K (phosphoinositide 3 kinase) and ILK (integrin linked kinase), whereas ACh (acetylcholine) acting via G(i)3 coupled M2 receptors preferentially activated PI3K, Cdc42 (cell division cycle 42)/Rac1, PAK1 (p21 activated kinase 1) and p38 MAPK (mitogen activated protein kinase). RNASE1 addiction withdrawal 15785859 In contrast, that of Rac1 did not change after the withdrawal. PROS1 drug cocaine 21796101 Among the daily cocaine induced changes in redox homeostasis were an increase in protein S glutathionylation and a decrease in expression of GSH S transferase pi (GSTpi). PROS1 drug cannabinoid 17432216 Marijuana may have accelerated stroke onset, but essential cause of stroke in this case must be protein S mutation. PROS1 drug alcohol 6539134 The content of the neurospecific protein S 100 in the cerebellum measured by rocket immunoelectrophoresis was demonstrated to be the same in animals preferring water and ethanol. OTP drug nicotine 32222562 We described past year OTP (i.e., cigars/cigarillos, waterpipe, sundry tobacco products (i.e., pipe, bidis, chewing tobacco, snuff)) use and ND over 4 years in these groups. OTP drug nicotine 32222562 At age 20, sustained smokers reported using a mean(SD) of 1.1(0.9) OTP in the past year; relapsers reported 0.5(0.6); shorter term quitters reported 0.9(0.7); longer term quitters reported 0.3(0.6); and never smokers reported 0.2(0.4). OTP drug nicotine 32222562 There was no change in OTP use or ND in never smokers and longer term quitters. OTP drug nicotine 32222562 OTP use and ND were stable in early adulthood among never smokers, sustained smokers and longer term quitters, but fluctuated in parallel with stopping and starting to smoke. OTP addiction addiction 28961545 Baseline Addiction Severity Index data were examined along with publicly available dates of arrest and arrest charges from the year before and after OTP entry. OTP drug cannabinoid 28952897 Participants who reported cannabis use on ≥5 days per week were recruited from an urban, outpatient opioid treatment program (OTP). OTP drug opioid 28952897 Participants who reported cannabis use on ≥5 days per week were recruited from an urban, outpatient opioid treatment program (OTP). OTP drug opioid 28952897 Participants were randomized to either four weeks of standard OTP clinical care (SCC; medication assisted treatment for opioid use disorder and individual behavioral counseling), followed by four weeks of SCC plus varenicline (SCC+VT), or to four weeks of SCC+VT followed by four weeks of SCC. OTP drug opioid 28854060 In a nationwide prevalence study, 69,140 patients newly admitted to an opioid treatment program (OTP) completed a brief self administered survey of past month heroin use and PO misuse from January 2005 through September 2016. OTP drug opioid 28854060 We calculated heroin use and PO misuse prevalence rates, and prevalence rate ratios of Black and Latino OTP entrants compared to White entrants over time. OTP drug opioid 28854060 Among OTP entrants, racially/ethnically disparate rates of heroin use, and to a lesser extent, of PO misuse have become more similar over time. OTP drug nicotine 28711748 The goal of this study was to test the hypothesis that personality traits related to affect regulation would be associated with greater frequency of other tobacco product (OTP) use in a sample of young adult non daily smokers. OTP addiction relapse 28711748 Longitudinal negative binomial regression models indicated that greater sensation seeking and lack of premeditation were associated with more frequent OTP use (ps<0.05). OTP drug nicotine 28711748 Young, non daily cigarette smokers with high levels of sensation seeking and/or lack of premeditation may be at increased risk for harms related to OTP use and may benefit from prevention and cessation strategies that specifically address affect. OTP addiction relapse 28711748 Young, non daily cigarette smokers with high levels of sensation seeking and/or lack of premeditation may be at increased risk for harms related to OTP use and may benefit from prevention and cessation strategies that specifically address affect. OTP drug nicotine 28633484 Weighted regression analyses for smoking status, time to first cigarette, cigarettes per day and non cigarette other tobacco products (OTP) were conducted across education levels. OTP addiction addiction 28543418 An OTP can be ethically justified as a tool to prevent and treat iatrogenic addiction under a specific paradigm one that adopts a default position of professional epistemic humility and holds all collaborative parties accountable in chronic pain management. OTP addiction intoxication 28495220 OTP use among young adult LGB bar patrons and the relationship among past quit attempts, intention to quit, and binge drinking with OTP use was examined. OTP drug opioid 28107680 Study design was a 2 (In Prison Treatment: Condition: Buprenorphine Treatment: vs. Counseling Only)×2 [Post Release Service Setting Condition: Opioid Treatment: Program (OTP) vs. Community Health Center (CHC)]×2 (Gender) factorial design. OTP drug nicotine 27664553 Little is known about types of OTP used and the reasons for use, and how OTP use and reasons for use correlate with smoking patterns and nicotine dependence in daily and nondaily smokers. OTP addiction dependence 27664553 Little is known about types of OTP used and the reasons for use, and how OTP use and reasons for use correlate with smoking patterns and nicotine dependence in daily and nondaily smokers. OTP drug nicotine 27664553 Logistic regression models assessed the association of smoking status with OTP use (ever and current) and reasons for use. OTP drug nicotine 27664553 Within each smoking group, separate logistic regression models examined the associations of OTP use and reasons for use with cigarette consumption and nicotine dependence. OTP addiction dependence 27664553 Within each smoking group, separate logistic regression models examined the associations of OTP use and reasons for use with cigarette consumption and nicotine dependence. OTP drug nicotine 27664553 Among non daily smokers, nicotine dependence was associated with a higher likelihood of current OTP use (OR=1.04 [95% CI 1.01 1.07]; p<0.05), whereas cigarette consumption was not. OTP addiction dependence 27664553 Among non daily smokers, nicotine dependence was associated with a higher likelihood of current OTP use (OR=1.04 [95% CI 1.01 1.07]; p<0.05), whereas cigarette consumption was not. OTP drug nicotine 27664553 Results suggest OTP use in nondaily smokers does not correlate with less frequent smoking, but may correlate with higher nicotine dependence. OTP addiction dependence 27664553 Results suggest OTP use in nondaily smokers does not correlate with less frequent smoking, but may correlate with higher nicotine dependence. OTP drug opioid 27745534 This report identifies the institutional barriers to, and benefits of, buprenorphine maintenance treatment (BMT) integration in an established hospital based opioid treatment program (OTP). OTP drug opioid 27745534 This case study presents the authors' experiences at the clinic, hospital, and corporation levels during efforts to integrate BMT into a hospital based OTP in New York City and a descriptive quantitative analysis of the characteristics of hospital outpatients treated with buprenorphine from 2006 to 2013 (N=735). OTP drug nicotine 27707516 We examined the associations between tobacco marketing receptivity and other tobacco product (OTP) use among young adult bar patrons (aged 18 26 years). OTP drug nicotine 27707516 Multivariable logistic regression analyses in 2015 examined if tobacco marketing receptivity was associated (1) with current (past 30 day) OTP use controlling for demographic factors and (2) with dual/poly use among current cigarette smokers (n = 3,045), controlling for demographics and nicotine dependence. OTP addiction dependence 27707516 Multivariable logistic regression analyses in 2015 examined if tobacco marketing receptivity was associated (1) with current (past 30 day) OTP use controlling for demographic factors and (2) with dual/poly use among current cigarette smokers (n = 3,045), controlling for demographics and nicotine dependence. OTP drug nicotine 27707516 Among the entire sample of young adult bar patrons (Meanage = 23.7, standard deviation = 1.8; 48.1% female), marketing receptivity was consistently associated with current use of all OTP including smokeless tobacco (adjusted odds ratio [AOR]= 2.56, 95% confidence interval [CI] 2.08 3.16, p < .001), hookah (AOR = 1.97, 95% CI 1.58 2.43, p < .001), cigarillos (AOR = 3.00, 95% CI 2.21 4.08, p < .001), electronic cigarettes (AOR = 2.43, 95% CI 1.93 3.04, p < .001), and multiple tobacco products (AOR = 2.93, 95% CI 2.45 3.51, p < .001). OTP drug nicotine 27707516 OTP use is common among young adult bar patrons, and it is associated with tobacco marketing receptivity. OTP drug nicotine 27707516 Efforts to limit tobacco marketing should address OTP in addition to cigarettes.

OTP addiction addiction 18615321 In a randomized controlled trial the effectiveness of an outreach treatment program (OTP) was compared with standard addiction care services for hard drug addicts in Rotterdam (The Netherlands). OTP drug opioid 15943950 In a cross sectional and longitudinal analysis, we compared patients entering a clinical trial of buprenorphine in a Primary Care Clinic (PCC) and those entering a local Opioid Treatment Program (OTP) and we compared the clinical characteristics and treatment outcomes of PCC patients with no history of methadone treatment (new to treatment) to those with prior methadone treatment. OTP drug opioid 15943950 OTP subjects (N=94) were enrolled in methadone maintenance during the same time period. OTP drug opioid 15943950 PCC subjects compared with OTP subjects were more likely to be male (77% versus 55%, p<0.01), full time employed (46% versus 15%, p<0.001), have no history of methadone treatment (46% versus 61%, p<0.05), have fewer years of opioid dependence (10 versus 15, p<0.001), and lower rates of injection drug use (IDU) (44% versus 60%, p=0.03).

MYOGLOBIN drug amphetamine 29566034 A relevant myoglobin decoration of renal tubules was only shown for methamphetamine abuse in the study presented. MYOGLOBIN drug amphetamine 28835159 We investigated whether METH dependence and METH induced psychosis may involve an effect on DNA methylation of the PVALB promoter. MYOGLOBIN addiction dependence 28835159 We investigated whether METH dependence and METH induced psychosis may involve an effect on DNA methylation of the PVALB promoter. MYOGLOBIN drug amphetamine 28835159 The methylation of a PVALB promoter sequence was determined in 100 METH dependent and 102 control subjects using pyrosequencing. MYOGLOBIN drug amphetamine 28835159 A significant increase in PVALB methylation was observed in METH dependence and METH induced psychosis. MYOGLOBIN addiction dependence 28835159 A significant increase in PVALB methylation was observed in METH dependence and METH induced psychosis. MYOGLOBIN drug amphetamine 28835159 These results demonstrate a specific association between elevated PVALB methylation and METH induced psychosis.

MYOGLOBIN drug alcohol 26156494 Composition dependent multiple structural transformations of myoglobin in aqueous ethanol solution: a combined experimental and theoretical study. MYOGLOBIN drug alcohol 26156494 Experimental studies (circular dichroism and ultra violet (UV) absorption spectra) and large scale atomistic molecular dynamics simulations (accompanied by order parameter analyses) are combined to establish a number of remarkable (and unforeseen) structural transformations of protein myoglobin in aqueous ethanol mixture at various ethanol concentrations. MYOGLOBIN addiction relapse 25623945 Behavioral characterization of our transgenic (Tg) mice uncovered that the Pvalb/Gad1 Tg mice have pronounced sensorimotor gating deficits, increased novelty seeking and reduced fear extinction. MYOGLOBIN addiction relapse 25623945 Our results suggest that reduction of GABAergic transmission from PVALB+ interneurons primarily impacts behavioral domains related to fear and novelty seeking and that these alterations might be related to the behavioral phenotype observed in schizophrenia. MYOGLOBIN drug psychedelics 12835872 We report the case of a 21 year old male who took a suicidal overdose of MDMA and subsequently developed severe hyperpyrexia (>43 degrees C/109.4 degrees F), rhabdomyolysis with an initial myoglobin level of 88,000 microg/l, disseminated intravascular coagulation (DIC) and beginning renal and liver failure. MYOGLOBIN drug alcohol 9046374 Binge drinking of alcohol, cocaine overdose, or overexertion can lead to rhabdomyolysis characterized by elevated creatine kinase (CK) and myoglobin in the serum, myoglobinuria, and muscle tenderness.

MYOGLOBIN addiction intoxication 9046374 Binge drinking of alcohol, cocaine overdose, or overexertion can lead to rhabdomyolysis characterized by elevated creatine kinase (CK) and myoglobin in the serum, myoglobinuria, and muscle tenderness. MYOGLOBIN drug alcohol 3716884 Ethanol reduces myoglobin release during isokinetic muscle exercise. MYOGLOBIN drug alcohol 3716884 Although the performed muscle work, maximal heart rate, and blood lactate levels did not differ between the three test occasions, the serum myoglobin increments after exercise were significantly reduced (p less than 0.05) in the ethanol intoxicated state and also 10 15 hours after ethanol intake. MYOGLOBIN drug alcohol 3716884 The mechanism, therefore, is likely to be a reduction of myoglobin release from skeletal muscle due to an ethanol induced alteration of the muscle cell membrane, possibly by means of adenylate cyclase activation. MYOGLOBIN drug alcohol 6872872 Non infarct associated increases of myoglobin in serum were seen in patients with terminal renal failure, severe shock, muscle trauma, muscle diseases, alcohol intoxication and after reanimation. MYOGLOBIN addiction intoxication 6872872 Non infarct associated increases of myoglobin in serum were seen in patients with terminal renal failure, severe shock, muscle trauma, muscle diseases, alcohol intoxication and after reanimation. MYOGLOBIN drug alcohol 6255983 Considered in conjunction with related parameters from ferrihemoglobin and ferrimyoglobin, the spectral and thermodynamic data are consistent with models in which methanol is bound directly to the ferric ion of cytochrome c, methanol and ethanol are bound directly to the ferric ions of hemoglobin and myoglobin, and 1 propanol is bound to a hydrophobic region of cytochrome c. Both the absolute and alcohol induced optical difference spectra of these proteins have been simulated, the former through summation of Gaussian bands and the latter as the difference between two such summations, one with parameters slightly altered from the other. GRIA3 drug amphetamine 31146278 Here, for methamphetamine, we observed no significant change in surface or total GluA1 (GluA2 and GluA3 were also unchanged).

GRIA3 drug amphetamine 29338492 We observed no evidence of association with METH dependence and METH dependent psychosis in the GRIA1 and GRIA2 polymorphisms, nor with single polymorphisms rs3761554 and rs989638 in GRIA3. GRIA3 addiction dependence 29338492 We observed no evidence of association with METH dependence and METH dependent psychosis in the GRIA1 and GRIA2 polymorphisms, nor with single polymorphisms rs3761554 and rs989638 in GRIA3. GRIA3 drug amphetamine 29338492 An association of GRIA3 rs502434 was identified with both METH dependence and METH dependent psychosis, although this did not withstand correction for multiple testing. GRIA3 addiction dependence 29338492 An association of GRIA3 rs502434 was identified with both METH dependence and METH dependent psychosis, although this did not withstand correction for multiple testing. GRIA3 drug amphetamine 29338492 These preliminary findings indicate that genetic variability in GRIA3 may interact with a functional BDNF polymorphism to provide a strong risk factor for the development of METH dependence in the Thai population.

GRIA3 drug cocaine 25539508 However, in cocaine sensitized mice primed with cocaine, this inhibition was reversed and a strong increase was detected in the mGluR5, NR2 subunits, and both GluR1 and GluR3. GRIA3 drug amphetamine 24535653 FR increased GluA1 in the PSD, and D amphetamine increased p Ser845 GluA1, GluA1, GluA2, but not GluA3, with a greater effect in FR than AL rats. GRIA3 drug alcohol 24523671 Out of the 16 glutamate receptor subunits, mRNAs encoding two AMPA [2 amino 3 (3 hydroxy 5 methyl isoxazol 4 yl)propanoic acid] receptor subunits GluA2 and GluA3; three kainate receptor subunits GluK2, GluK3 and GluK5 and five NMDA (N methyl D aspartate) receptor subunits GluN1, GluN2A, GluN2C, GluN2D, and GluN3A were significantly increased in the HP DG region in alcoholics. GRIA3 drug alcohol 22291662 Expression levels of GRIA3 flip and flop and GRIA4 flop mRNAs in this region were positively correlated with daily ethanol intake and blood ethanol concentrations (BEC) averaged over the 6 months prior to necropsy. GRIA3 drug cocaine 21216391 Among them, GluA1 and GluA3 are preferentially upregulated in their palmitoylation levels by a systemic injection of cocaine. GRIA3 drug cocaine 20868701 Under basal conditions and in response to a single cocaine injection the levels of GluR1, GluR2, and GluR3 AMPA receptor subunits did not differ between WT and 5 LOX deficient mice, but the response of GluR1 phosphorylation to a single cocaine injection was greater under the 5 LOX deficiency. GRIA3 drug opioid 20159947 Immunoblotting studies show that 12 h after morphine treatment, GluR1 subunits are increased at the postsynaptic density (PSD) and at extrasynaptic sites, whereas GluR3 subunits are only increased at the PSD, and they show how this alters receptor subunit composition. GRIA3 drug opioid 18671727 Decreased AMPA GluR2, but not GluR3, mRNA expression in rat amygdala and dorsal hippocampus following morphine induced behavioural sensitization. GRIA3 addiction sensitization 18671727 Decreased AMPA GluR2, but not GluR3, mRNA expression in rat amygdala and dorsal hippocampus following morphine induced behavioural sensitization. GRIA3 drug opioid 18671727 In order to evaluate the mechanism underlying the behavioural responses, quantitative real time reverse transcription polymerase chain reaction was used to evaluate mRNA expression of the AMPA receptor subunits GluR2 and GluR3 in the striatum, prefrontal cortex, hippocampus, hypothalamus and amygdala of animals treated repeatedly with morphine. GRIA3 drug opioid 18671727 Repeated morphine treatment did not alter GluR3 mRNA expression in any brain area assessed. GRIA3 drug psychedelics 18419818 The aim of the present study was to investigate the effect of repeated intermittent MDMA administration upon gene transcript expression of the glutamate transporters (EAAT1, EAAT2 1, EAAT2 2), the glutamate receptor subunits of AMPA (GluR1, GluR2, GluR3), the glutamate receptor subunits of NMDA (NR1, NR2A and NR2B), as well as metabotropic glutamate receptors (mGluR1, mGluR2, mGluR3, mGluR5) in six different brain regions.

GRIA3 drug amphetamine 9183816 Repeated amphetamine administration decreased levels of GluR1 and GluR2 but not GluR3 mRNAs in both core and shell subregions of the NAc at the 14 day withdrawal time; no changes were observed after 3 days of withdrawal. GRIA3 addiction withdrawal 9183816 Repeated amphetamine administration decreased levels of GluR1 and GluR2 but not GluR3 mRNAs in both core and shell subregions of the NAc at the 14 day withdrawal time; no changes were observed after 3 days of withdrawal. DDIT3 drug amphetamine 32203791 We further examined ER stress related proteins and mitochondrial apoptosis pathway in the VTA and NAc, and found that METH increased the expressions of glucose regulated protein 78 (GRP78), C/EBP homologous protein (CHOP), and Bax, as same time decreased the expressions of procaspase12, Bcl 2, and procaspase3, while Trx 1 overexpression blocked these changes. DDIT3 drug amphetamine 31396089 Ad libitum HRW consumption also had an inhibitory effect on the METH induced increase in the expression of Bax/Bcl 2, cleaved caspase 3, glucose related protein 78 (GRP 78), CCAAT/enhancer binding protein homologous protein (CHOP), and p NF kB p65 expression and elevation of interleukin (IL) 6 and tumor necrosis factor (TNF) α levels in the hippocampus. DDIT3 drug alcohol 31105269 Alcohol increased IL 17A production and pro apoptotic signaling evidenced by Bax, Bim, caspase 3, and caspase 8 increases via endoplasmic reticulum (ER) stress indicated by C/EBP homologous protein (CHOP) upregulation; this was prevented by the ER stress inhibitor, 4 PBA, in isolated crypts in vitro and in vivo.

ANG drug opioid 17408935 Rats were allowed to recover from the surgery and conditioned place preference was induced by morphine, and the time spent in morphine compartment was compared in saline, morphine, captopril and Ang II groups. ANG drug opioid 17408935 Morphine withdrawal signs were compared in three other groups of rats: morphine alone, captopril+morphine and Ang II+morphine 4 days after morphine injections (three times in each day) with naloxone injection on 4th day. ANG addiction withdrawal 17408935 Morphine withdrawal signs were compared in three other groups of rats: morphine alone, captopril+morphine and Ang II+morphine 4 days after morphine injections (three times in each day) with naloxone injection on 4th day. ANG drug opioid 17408935 Results with rats conditioned place preference induced by morphine showed that icv captopril decreased significantly the time in morphine compartment (P<0.01) while Ang II had no effect. ANG drug opioid 17408935 Ang II administration augmented some of withdrawal signs than in the morphine group (P<0.01 and P<0.001). ANG addiction withdrawal 17408935 Ang II administration augmented some of withdrawal signs than in the morphine group (P<0.01 and P<0.001). ANG drug alcohol 9305468 Ang II impairment of retention and ethanol inhibition of LTP can both be blocked by pretreatment with losartan. ANG drug alcohol 9305468 Results confirmed the general hypothesis that ethanol induced cognitive deficits are mediated by Ang II and the AT1 receptor and that the impairment can be reduced by pretreatment with losartan. ANG drug alcohol 8840909 Mice that were habituated to drinking ethanol solution and mice that had drunk water only (naive mice) were given an ICV infusion of angiotensin II (Ang II) at 2.9 ng/h for 8 days to determine the effect of chronic ethanol intake on the ingestive response to this potent dipsogen. ANG drug alcohol 8840909 Ang II infusion in alcohol naive mice increased daily water intake from 3.7 +/ 0.2 ml (mean +/ SE, n = 6) to 11.0 +/ 1.5 ml on day 4 (p < 0.001) and to 18.3 +/ 2.6 ml on day 8 (p < 0.001). ANG drug alcohol 8840909 In subsequent experiments, mice had access to 4% ethanol solution up to day 4 and then to water for 4 days during the Ang II infusion. ANG drug alcohol 8840909 Taste aversion, plus previous experience from ingestion of ethanol in habituated mice, may explain the rejection of ethanol to quench Ang II induced thirst. ANG addiction aversion 8840909 Taste aversion, plus previous experience from ingestion of ethanol in habituated mice, may explain the rejection of ethanol to quench Ang II induced thirst. ANG drug alcohol 8724449 Neurotensin enhances some of the behavioral effects of alcohol including motor impairment, narcosis, hypothermia and also interacts with some of the physiological actions of angiotensin (ANG) II including aldosterone release and increased blood pressure. ANG drug alcohol 8724449 ANG II injections also produce a dose dependent antagonist reversible reduction in alcohol drinking. ANG drug alcohol 8724449 When intake stabilized ANG II (400 micrograms/kg per day) or vehicle were administered subcutaneously (SC) just prior to alcohol availability but only the group receiving ANG II showed a marked reduction in alcohol intake. ANG drug alcohol 8724449 Neurotensin alone did not affect alcohol intake at any of the doses tested but did attenuate, in a dose dependent fashion, the reduction in alcohol intake produced by ANG II. ANG drug alcohol 8724449 These results demonstrate neurotensin's ability to alter the behavioral effect of ANG II on alcohol intake. ANG drug alcohol 7748510 Because weight reduction alters angiotensin (ANG) II activity, and ANG II is known to modulate alcohol intake, ANG II may play a role in the enhanced alcohol consumption of food deprived weight reduced rats and in the drop in alcohol intake when these rats are refed. ANG drug alcohol 7748510 These findings suggest that the increase in alcohol intake with food restriction and its decline following refeeding are, in part, related to changes in ANG II activity. ANG drug alcohol 3149773 Angiotensin II (ANG II) administered (ICV, 2.0 micrograms) 12 h after the withdrawal of the alcohol not only neutralized the toxic effect of ethanol but also improved learning. ANG addiction withdrawal 3149773 Angiotensin II (ANG II) administered (ICV, 2.0 micrograms) 12 h after the withdrawal of the alcohol not only neutralized the toxic effect of ethanol but also improved learning. ANG drug alcohol 3149773 When administered on the 5th day after ethanol withdrawal, the effect of ANG II was weaker. ANG addiction withdrawal 3149773 When administered on the 5th day after ethanol withdrawal, the effect of ANG II was weaker. ANG drug alcohol 3149773 It was shown that both chronic alcohol treatment and ANG II alone increased apomorphine (1 mg/kg) and amphetamine (7.5 mg/kg) stereotypy but the effects of ANG II were greater. ANG drug amphetamine 3149773 It was shown that both chronic alcohol treatment and ANG II alone increased apomorphine (1 mg/kg) and amphetamine (7.5 mg/kg) stereotypy but the effects of ANG II were greater. ANG drug alcohol 3149773 ANG II did not change the stereotypy induced by amphetamine but increased the stereotypy induced by apomorphine in the group of animals chronically treated with alcohol. ANG drug amphetamine 3149773 ANG II did not change the stereotypy induced by amphetamine but increased the stereotypy induced by apomorphine in the group of animals chronically treated with alcohol. ANG drug alcohol 3149773 ANG II alone intensified catalepsy and eliminated the effect of ethanol. ANG drug alcohol 3149773 Both ANG II and alcohol increased striatal dopamine (DA) concentration. ANG drug alcohol 3149773 This effect of ANG II was significantly greater in the animals chronically treated with alcohol. ANG drug alcohol 3149773 The results suggest involvement of the central dopaminergic system in the effect of ANG II on the ethanol induced impairment of acquisition of active avoidance but, however, the results of the biochemical determinations of DA turnover do not provide an explanation of these changes. AFP drug alcohol 20844957 The predictors of surveillance intent for AFP were absence of alcoholism, abdominal pain, ascites, diabetes and high AST levels. AFP addiction dependence 20844957 For US, the predictors of surveillance were prior AFP testing and HIV status and absence of abdominal pain, ascites, or drug dependence.

AFP addiction intoxication 6178134 After CCl4 intoxication of low and high AFP producing mouse strains, cellular AFP is found in hepatocytes of portal, periportal and intermediate zones. ABETA drug alcohol 31733664 Bioinformatics identified the AD associated proteins MAPT (Tau), amyloid beta precursor protein (APP), and presenilin 1 (PSEN 1) as the main modulators of alcohol sensitive protein networks that included AD related proteins that regulate energy metabolism (ATP5D, HK1, AK1, PGAM1, CKB), cytoskeletal development (BASP1, CAP1, DPYSL2 [CRMP2], ALDOA, TUBA1A, CFL2, ACTG1), cellular/oxidative stress (HSPA5, HSPA8, ENO1, ENO2), and DNA regulation (PURA, YWHAZ). ABETA drug opioid 18521004 Morphine inhibits herpetic allodynia through mu opioid receptors induced in Abeta fiber neurons. ABETA drug opioid 18521004 Mechanical allodynia is mainly mediated by Abeta fibers, whereas mu opioid receptors are present in C and Adelta fibers. ABETA drug opioid 18521004 Viral propagation in the sensory ganglion may induce mu opioid receptor expression in Abeta fibers, which may be responsible for the inhibitory action of local opioids on mechanical allodynia in mice with herpetic pain. ABETA addiction withdrawal 18088441 Furthermore, in a novel electrical stimulation induced paw withdrawal (EPW) test, the thresholds for stimulation through C , Adelta and Abeta fibers were all decreased by AS ODN pretreatments. ABETA drug alcohol 17253767 Abeta binding alcohol dehydrogenase (ABAD) is an NAD dependent mitochondrial dehydrogenase. ABETA addiction dependence 17253767 In this study, surface plasmon resonance (SPR) was employed to determine the temperature dependence of the affinity of the ABAD Abeta interaction. ABETA addiction reward 16372134 Here, genetic association of the common R219K variant of ABCA1 is shown with cerebrospinal fluid (CSF) Abeta 1 42 levels, reinforcing emerging evidence of a connection between lipid and Abeta metabolism. ABETA drug alcohol 16340465 Therefore, the current studies aimed to investigate the effects of exposure to 50 or 100 mM ethanol (EtOH) and withdrawal on hippocampal injury induced by Abeta peptide treatment. ABETA addiction withdrawal 16340465 Therefore, the current studies aimed to investigate the effects of exposure to 50 or 100 mM ethanol (EtOH) and withdrawal on hippocampal injury induced by Abeta peptide treatment. ABETA drug alcohol 16340465 The present studies exposed organotypic hippocampal slice cultures to 50 or 100 mM ethanol (EtOH) for 10 days, after which the slices underwent ethanol withdrawal (EWD) in the presence of varying concentrations of Abeta 25 35 (0.1, 1, 10 microM), or 35 25 (200 microM), a negative control reverse sequence peptide. ABETA addiction withdrawal 16340465 The present studies exposed organotypic hippocampal slice cultures to 50 or 100 mM ethanol (EtOH) for 10 days, after which the slices underwent ethanol withdrawal (EWD) in the presence of varying concentrations of Abeta 25 35 (0.1, 1, 10 microM), or 35 25 (200 microM), a negative control reverse sequence peptide. ABETA drug alcohol 16340465 Exposure to Abeta in ethanol naïve cultures did not produce significant cytotoxicity. ABETA addiction withdrawal 16340465 Further, this EtOH exposure and withdrawal regimen sensitizes the hippocampus to the toxic effects of Abeta treatment in a manner reflecting over activity of NMDA receptor function. ABETA drug nicotine 12970390 Using these cells as a model system, we designed experiments to more directly determine whether Abeta peptides (Abeta1 42 and Abeta1 40) interfere with a potential nicotinic cytoprotective action and with the ability of nicotine to increase intracellular Ca2+. TRPA1 drug alcohol 31412038 Mice avoided water sources surrounded by both volatile TRPV1 (cyclohexanone) and TRPA1 (allyl isothiocyanate) irritants and the aversion to cyclohexanone was mitigated when combined with a pure odorant (rose fragrance, phenylethyl alcohol, PEA). TRPA1 addiction aversion 31412038 Mice avoided water sources surrounded by both volatile TRPV1 (cyclohexanone) and TRPA1 (allyl isothiocyanate) irritants and the aversion to cyclohexanone was mitigated when combined with a pure odorant (rose fragrance, phenylethyl alcohol, PEA). TRPA1 drug cannabinoid 31096838 Finally, we analyzed cannabinoid responses at nociceptive channels other than TRPV1 (TRPV2, TRPM8, and TRPA1), and report that cannabinoids differentially activate these channels. TRPA1 addiction sensitization 29976627 Using behavioral readouts of pain hypersensitivity induced by angiotensin II (Ang II) injection into mouse hindpaws, our study shows that activation of the type 2 Ang II receptor (AT2R) and the cell damage sensing ion channel TRPA1 are required for peripheral mechanical pain sensitization induced by Ang II in male and female mice. TRPA1 addiction sensitization 29430557 It has been shown in rat models that repeated exposure to acrolein induces trigeminovascular sensitization to both TRPA1 and TRP vanilloid 1 (TRPV1) agonists, a phenomenon linked to headache. TRPA1 addiction sensitization 29430557 These data support the hypothesis that lipid signaling may represent a mechanism by which repeated exposure to the TRPA1 agonist and environmental toxin, acrolein, drives trigeminovascular sensitization. TRPA1 drug nicotine 29247491 The hydrophilic nicotine was ineffective unless applied unprotonated in alkaline (pH9) solution, activating TRPA1 and TRPV1. TRPA1 addiction sensitization 28126501 The prevention of this hyperalgesia by diclofenac (1 10μg), the inhibitors of COX 1 SC 560 (0.1 1μg) or COX 2 celecoxib (1 5μg), the TRPV1 antagonist capsazepine (0.03 0.3μg) or the TRPA1 antagonist HC030031 (10 50μg) demonstrates the involvement of prostaglandin synthesis and TRP sensitization in CCL5 evoked hyperalgesia. TRPA1 addiction sensitization 26480812 Human and animal studies indicate a critical role for oxidative stress and activation of transient receptor potential (TRP) cation channel subfamily members TRPV1 and TRPA1 on pancreatic nociceptors in sensitization mechanisms that result in pain. TRPA1 drug nicotine 26142526 Effects of nicotine, a known chemical irritant and agonist of TRPA1 are also inhibited by borneol in both systems. TRPA1 drug nicotine 26142526 It is concluded that borneol, being an inhibitor of TRPA1, could be a safer therapeutic combination in clinical situations where TRPA1 channelopathies like neuropathic pain, trigeminal neuralgia or nicotine withdrawal treatments are involved. TRPA1 addiction withdrawal 26142526 It is concluded that borneol, being an inhibitor of TRPA1, could be a safer therapeutic combination in clinical situations where TRPA1 channelopathies like neuropathic pain, trigeminal neuralgia or nicotine withdrawal treatments are involved. TRPA1 drug cannabinoid 23956775 Selective ionotropic cannabinoids may also produce cross desensitization of the TRPA1 TRPV1 heteromeric nociceptor channels by being negative allosteric modulators of these channels leading to antinociception and antihyperalgesia. TRPA1 drug alcohol 23446826 [Dimensions of parental rearing styles in alcohol dependent patients: first results of the questionnaire on parental attitudes and rearing practices (FEPS)]. TRPA1 drug alcohol 23446826 Therefore the aim of this study was the confirmatory evaluation of the factor structure of the Questionnaire on Parental Attitudes and Rearing Practices (FEPS) in 186 alcohol dependent patients. TRPA1 drug alcohol 23446826 These results indicate the factorial validity of the FEPS in patients with alcohol dependence. TRPA1 addiction dependence 23446826 These results indicate the factorial validity of the FEPS in patients with alcohol dependence. TRPA1 drug cannabinoid 23337417 The mechanism of analgesic action of topical propofol is not clear, but may involve desensitization of TRPV1 or TRPA1 receptors expressed in peripheral nociceptive nerve endings, engagement of endocannabinoids, or activation of peripheral γ aminobutyric acid A receptors. TRPA1 drug nicotine 22618163 It also showed strain specificity, generalizing to hydrogen peroxide (an activator of TRPA1) in C57BL/6J mice and to the olfactory cue of nicotine in DBA/2J mice. TRPA1 drug alcohol 22378825 Fetal ethanol exposure attenuates aversive oral effects of TrpV1, but not TrpA1 agonists in rats. TRPA1 addiction aversion 22378825 Fetal ethanol exposure attenuates aversive oral effects of TrpV1, but not TrpA1 agonists in rats. TRPA1 addiction aversion 22378825 We focused on two excitatory ligand gated ion channels, TrpV1 and TrpA1, which are expressed in oral trigeminal neurons and mediate the aversive orosensory response to many chemical irritants. TRPA1 addiction sensitization 22171045 Transient receptor potential subtype vanilloid 1 (TRPV1) and TRP ankyryn 1 (TRPA1) contribute importantly to the genesis of inflammatory pain via both peripheral mechanisms (peripheral sensitization) and spinal cord mechanisms (central sensitization). TRPA1 drug opioid 21395865 In these neurons, Ret is a critical regulator of several ion channels and receptors, including Nav1.8, Nav1.9, ASIC2a, P2X3, TrpC3, TrpM8, TrpA1, delta opioid receptor, MrgD, MrgA1 and MrgB4. TRPA1 drug opioid 19371406 High concentrations of morphine sensitize and activate mouse dorsal root ganglia via TRPV1 and TRPA1 receptors. TRPA1 drug opioid 19371406 To study a possible involvement of TRP receptors in the pro nociceptive effects of morphine (0.3 10 mM), two models of nociception were employed using C57BL/6 mice and genetically related TRPV1 and TRPA1 knockout animals, which were crossed and generated double knockouts. TRPA1 drug opioid 19371406 Morphine induced release of calcitonin gene related peptide and sensitized the release evoked by heat or the TRPA1 agonist acrolein. TRPA1 drug opioid 19371406 Morphine activated HEK293t cells transfected with TRPV1 or TRPA1. TRPA1 drug opioid 19371406 In neurons from TRPV1 and TRPA1 knockout animals activation by morphine was markedly reduced, in the TRPV1/A1 double knockout animals this morphine effect was abrogated.

RET drug alcohol 31617071 Evidence has emerged that 5 RTKs (tropomyosin related kinase B (TrkB), RET proto oncogene (RET), anaplastic lymphoma kinase (ALK), fibroblast growth factor receptor (FGFR), and epidermal growth factor receptor (EGFR)) modulate alcohol drinking and other behaviors related to alcohol addiction. RET addiction addiction 31617071 Evidence has emerged that 5 RTKs (tropomyosin related kinase B (TrkB), RET proto oncogene (RET), anaplastic lymphoma kinase (ALK), fibroblast growth factor receptor (FGFR), and epidermal growth factor receptor (EGFR)) modulate alcohol drinking and other behaviors related to alcohol addiction. RET drug alcohol 31617071 This review will examine the preclinical evidence describing TrkB, RET, ALK, FGFR, and EGFR modulation of alcohol drinking and other behaviors relevant to alcohol abuse. RET drug nicotine 29128428 In large retrospective studies, RET rearrangements correlate with adenocarcinoma histologic subtype, never smoking status, younger age, more advanced disease stage, potentially higher chemosensitivity (in particular, to pemetrexed based regimens), and coexistence of other genomic alterations. RET drug amphetamine 29031851 Constitutive Ret signaling leads to long lasting expression of amphetamine induced place conditioning via elevation of mesolimbic dopamine. RET drug amphetamine 29031851 The duration of amphetamine induced CPP was greatly enhanced in MEN2B mice, but not in the GDNF hypermorphic mice. RET addiction reward 29031851 The duration of amphetamine induced CPP was greatly enhanced in MEN2B mice, but not in the GDNF hypermorphic mice. RET addiction relapse 29031851 Together, our results suggest that downstream components of GDNF signaling, in this case Ret, may mediate persistent drug seeking behavior through increased TH expression and dopamine levels in the mesolimbic dopamine neurons. RET addiction addiction 26188473 We identified 78 miRNA and 150 mRNA transcripts that were differentially expressed (fdr adjusted p < 0.05, absolute log2 fold change >0.5); these included genes not previously associated with addiction (miR 125a 5p, miR 145 and Foxa1), loci encoding receptors related to drug addiction behaviors and genes with previously recognized roles in addiction such as miR 124, miR 181a, DAT and Ret. RET addiction dependence 25855381 In conclusion, our findings indicate that LADCs with ALK, RET, and ROS1 fusions develop exclusively via their dependence on these oncogene fusions. RET drug benzodiazepine 23195112 Given that the defensive factor was sensitive to drugs known to attenuate (alprazolam and chronic fluoxetine) and induce (caffeine) panic attack, we suggest the RET as a useful test to assess the effects of panicolytic and panicogenic drugs. RET drug nicotine 23150706 Patients with lung adenocarcinomas with RET fusion gene had more poorly differentiated tumors (63.6%; P = .029 for RET v ALK, P = .007 for RET v EGFR), with a tendency to be younger (≤ 60 years; 72.7%) and never smokers (81.8%) and to have solid subtype (63.6%) and a smaller tumor (≤ 3 cm) with N2 disease (54.4%). RET drug opioid 21395865 In these neurons, Ret is a critical regulator of several ion channels and receptors, including Nav1.8, Nav1.9, ASIC2a, P2X3, TrpC3, TrpM8, TrpA1, delta opioid receptor, MrgD, MrgA1 and MrgB4. RET addiction sensitization 21395865 Ret deficient mice fail to respond to mustard oil induced neurogenic inflammation, have elevated basal responses and a failure to terminate injury induced sensitization to cold stimuli, hypersensitivity to basal but not injury induced mechanical stimuli, while heat sensation is largely intact. RET drug amphetamine 19422887 Importantly, 10 of the regulated genes have been previously related with learning and memory or neural plasticity, including the cocaine and amphetamine regulated transcript (Cart), adenylate cyclase activating polypeptide 1 (Adcyap1), serum/glucocorticoid regulated kinase (Sgk), Ret proto oncogene (Ret), and Fos. RET drug cocaine 19422887 Importantly, 10 of the regulated genes have been previously related with learning and memory or neural plasticity, including the cocaine and amphetamine regulated transcript (Cart), adenylate cyclase activating polypeptide 1 (Adcyap1), serum/glucocorticoid regulated kinase (Sgk), Ret proto oncogene (Ret), and Fos. RET addiction sensitization 15836976 Mechanistically, the great majority of sensory fibers that innervate the bone are CGRP/TrkA expressing fibers, and if the sensitization and activation of these fibers is blocked by anti NGF therapy there would not be another population of nociceptors, such as the non peptidergic IB4/RET IR nerve fibers, to take their place in signaling nociceptive events. RET drug psychedelics 15659598 In dopaminergic neuron like SHSY5Y cells, ibogaine treatment upregulated the GDNF pathway as indicated by increases in phosphorylation of the GDNF receptor, Ret, and the downstream kinase, ERK1 (extracellular signal regulated kinase 1).

KCNH2 drug opioid 31748404 These results confirm that OREX 1019 has little or no efficacy at μ opioid receptorsand has low abuse potential, and, combined with promising safety (clean profile vs. other off target proteins including the hERG (human ether a go go related gene) K+ channel) and pharmacokinetic data (supporting administration by subcutaneous or sublingual routes, but with low oral bioavailability), suggest it could be a safe and effective alternative to current treatments for opioid use disorders particularly as applied to relapse prevention.

KCNH2 drug nicotine 29723392 Results were compared to data collected in non human primates and beagle dogs during pharmacological challenges and torsadogenic hERG blockers exposure, in 127 genotyped LQT1 patients on/off β blocker treatment and in subgroups of smoking and non smoking subjects. KCNH2 drug nicotine 29723392 S2 oscillations were proportionally increased by torsadogenic hERG blocking drugs, whereas smoking caused an increase in S3 oscillations. KCNH2 addiction dependence 28830713 Loperamide also altered the voltage dependence of steady state hERG current properties. KCNH2 drug psychedelics 26807959 CARDIOTOXICITY: Ether a go go related gene (hERG) potassium channels in the heart might play a crucial role in ibogaine's cardiotoxicity, as hERG channels are vital in the repolarization phase of cardiac action potentials and blockade by ibogaine delays this repolarization, resulting in QT (time interval between the start of the Q wave and the end of the T wave in the electrical cycle of the heart) interval prolongation and, subsequently, in arrhythmias and sudden cardiac arrest. KCNH2 drug benzodiazepine 25733807 So far, the effects of midazolam on cardiac human ether à go go related gene (hERG) channels have not been analyzed. KCNH2 drug benzodiazepine 25733807 The inhibitory effects of midazolam on heterologously expressed hERG channels were analyzed in Xenopus oocytes using the double electrode voltage clamp technique. KCNH2 drug benzodiazepine 25733807 We found that midazolam inhibits hERG channels in a concentration dependent manner, yielding an IC50 of 170 μM in Xenopus oocytes. KCNH2 drug benzodiazepine 25733807 Midazolam resulted in a small negative shift of the activation curve of hERG channels. KCNH2 drug benzodiazepine 25733807 Using the hERG pore mutants F656A and Y652A we provide evidence that midazolam uses a classical binding site within the channel pore. KCNH2 drug benzodiazepine 25733807 Analyzing the subacute effects of midazolam on hERG channel trafficking, we further found that midazolam does not affect channel surface expression. KCNH2 drug benzodiazepine 25733807 Taken together, we show that the anesthetic midazolam is a low affinity inhibitor of cardiac hERG channels without additional effects on channel surface expression. KCNH2 drug psychedelics 23707769 We have recently reported that ibogaine inhibits human ERG (hERG) potassium channels at concentrations similar to the drugs affinity for several of its known brain targets. KCNH2 drug psychedelics 23707769 We confirmed that heterologously expressed hERG currents are reduced by ibogaine in low micromolar concentrations. KCNH2 drug psychedelics 23707769 Unexpectedly, although blocking hERG channels, ibogaine did not prolong the action potential (AP) in guinea pig cardiomyocytes at low micromolar concentrations. KCNH2 drug opioid 23537174 Using both human and experimental animal studies it then presents the pharmacodynamic activity of parent drug and metabolites at the mu opioid receptor, as P glycoprotein substrates and plasma/brain concentration ratios, and activity at the hERG K(+) channel.

KCNH2 addiction addiction 22458604 Anti addiction drug ibogaine inhibits hERG channels: a cardiac arrhythmia risk. KCNH2 drug opioid 22381725 Many explorations have helped in understanding the physiopathology by showing that opioids, including methadone, cause a blockage of the potassium channels of the gene HERG K+P. KCNH2 drug amphetamine 21229349 Chronic METH treatment alone reduced the expression of AP1, Erg1 3, and Nr4a1 transcription factors below control levels. KCNH2 drug opioid 20930594 Using patch clamp recording in human stem cell derived cardiomyocytes and stably transfected mammalian cells, we found that methadone produced concentration dependent AP prolongation and ion channel block at low micromolar concentrations: hERG (IC50 = 1.7 μM), hNav1.5 (11.2 μM tonic block; 5.5 μM phasic block), and hCav1.2 (26.7 μM tonic block; 7.7 μM phasic block). KCNH2 drug benzodiazepine 20930594 However, coadministration of 1 μM diazepam with methadone caused a statistically significant increase in AP duration and a 4 fold attenuation of hNav1.5 block (IC50 values were 44.2 μM and 26.6 μM, respectively, for tonic and phasic block), with no significant effect on methadone induced block of hERG, hCav1.2, hKv4.3/hKChIP2.2, and hKvLQT1/hminK channels. KCNH2 drug opioid 20930594 However, coadministration of 1 μM diazepam with methadone caused a statistically significant increase in AP duration and a 4 fold attenuation of hNav1.5 block (IC50 values were 44.2 μM and 26.6 μM, respectively, for tonic and phasic block), with no significant effect on methadone induced block of hERG, hCav1.2, hKv4.3/hKChIP2.2, and hKvLQT1/hminK channels. KCNH2 drug benzodiazepine 20930594 Thus, although diazepam alone does not prolong the QT interval, the relief of methadone induced Na channel block may leave hERG K channel block uncompensated, thereby increasing cardiac risk. KCNH2 drug opioid 20930594 Thus, although diazepam alone does not prolong the QT interval, the relief of methadone induced Na channel block may leave hERG K channel block uncompensated, thereby increasing cardiac risk. KCNH2 drug opioid 18071169 To compare the effects of 3 known hERG associated channel blockers on the corrected QT (QTc), we conducted a randomized, controlled trial of opioid addicted subjects.

IGF1 drug alcohol 21959607 IGF I and IGFBP 3 before and after inpatient alcohol detoxification in alcohol dependent subjects. IGF1 drug alcohol 21959607 Alcohol abuse is associated with low IGF I levels that tend to rise after alcohol withdrawal. IGF1 addiction withdrawal 21959607 Alcohol abuse is associated with low IGF I levels that tend to rise after alcohol withdrawal. IGF1 drug alcohol 21959607 There is a paucity of studies on the course of IGFBP 3 (the main binding protein for IGF I) after alcohol detoxification. IGF1 drug alcohol 21959607 We prospectively assessed IGF I and IGFBP 3 changes at the time of admission and after 4 to 6 weeks of detoxification in an inpatient alcohol detoxification facility in 118 alcohol dependent subjects given a regular hospital diet. IGF1 drug alcohol 21959607 Changes in IGF I after alcohol detoxification showed a marked dimorphism in altered hepatic biochemistry upon admission, with a rise in those with normal liver enzymes upon admission (p = 0.016, Kruskall Wallis) and a drop in those with elevated liver enzymes upon admission (p = 0.05); the latter was noted in subjects that had consumed alcohol close to the time of admission. IGF1 drug alcohol 21959607 Overall, however, IGF I and IGFBP 3 were within normal limits for most subjects both upon admission and after alcohol detoxification; no significant differences were detected among the examined parameters in men vs. women, and there were no significant correlations of IGF I, IGFBP 3 or the IGF I/IGFBP 3 molar ratio with BMI or age. IGF1 drug alcohol 21959607 Regardless of hepatic enzymes' elevation, alcohol detoxification had overall slight effects on IGF I and IGFBP 3.

GAP43 drug opioid 29154860 Inhibition of Cav 1 expression reduced the morphine induced increase in the neuronal growth markers GAP 43 and MAP 2. GAP43 drug cocaine 26850084 We previously demonstrated that nELAV/GAP 43 pathway is pivotal for learning and its hippocampal expression is up regulated by acute stress following repeated cocaine administration. GAP43 drug cocaine 26850084 We therefore hypothesized that abstinence induced stress may sustain nELAV/GAP 43 pathway during early abstinence following 2 weeks of cocaine self administration. GAP43 drug cocaine 26850084 We found that contingent, but not non contingent, cocaine exposure selectively increases hippocampal nELAV, but not GAP 43, expression immediately after the last self administration session, an effect that wanes after 24 h and that comes back 7 days later when nELAV activation becomes associated with increased expression of GAP 43, an effect again observed only in animals self administering the psychostimulant. GAP43 drug cocaine 26850084 This nELAV profile suggests that its initial transient alteration is perhaps related to the daily administration of cocaine, while the increase in the nELAV/GAP 43 pathway following a week of abstinence may reflect the activation of this cascade as a target of stressful conditions associated with drug related memories.

GAP43 drug alcohol 21367572 The present study addresses the effects of a single acute ethanol exposure on growth associated protein 43 (GAP 43) and brain derived neurotrophic factor (BDNF) gene expression in neurons in the cerebellum and hippocampus of adolescent rats. GAP43 drug alcohol 21367572 Analyses of total RNA and protein by quantitative reverse transcription PCR and western blotting, respectively, revealed that this single ethanol exposure significantly decreased the levels of GAP 43 mRNA and protein in the cerebellum but increased the levels of mRNA and protein in the hippocampus.

GAP43 drug cocaine 21210085 Our results show that the combination of repeated exposure to cocaine and acute stress significantly enhances nELAV expression and phosphorylation in the hippocampus with a concomitant increase of GAP43 expression (a specific nELAV target), an effect that seems to involve, upstream, protein kinase C alpha (PKCα).

DAGLA drug cannabinoid 32057593 In the mPFC and hippocampus, EtOH rats had significantly higher mRNA expression of endocannabinoid signaling (mPFC: Ppara, Dagla, Daglb and Napepld; and hippocampus: Cnr2, Dagla and Mgll) and neuroinflammation associated genes (mPFC: Gfap; and hippocampus: Aif1) than in controls. DAGLA drug cannabinoid 30987110 Immunohistochemical staining further confirmed the presence of diacylglycerol lipase alpha, an endocannabinoid synthesizing enzyme, in oriens interneurons. DAGLA drug cannabinoid 27394933 Five genes known to play a role in the endocannabinoid system and CUDs were examined in a community sample of young adult Mexican Americans (MAs): CNR1, MGLL, FAAH, DAGLA, and DAGLB. DAGLA drug cannabinoid 26811312 Regarding the endocannabinoid system, acute and repeated cocaine administration were associated with an increased gene/protein expression of CB1 receptors and a decreased gene/protein expression of the endocannabinoid synthesis enzymes N acyl phosphatidylethanolamine D (NAPE PLD) and diacylglycerol lipase alpha (DAGLα).

ARRB2 drug opioid 28855588 We examined the involvement of MOPs, DOPs, β arr2 and c Src in the inhibition by morphine of GABAergic inhibitory postsynaptic currents (IPSCs) recorded from neurons in the mouse ventral tegmental area. ARRB2 drug opioid 28855588 Inhibition of IPSC frequency by morphine was also reduced in β arr2 / neurons in which PP2 caused no further reduction. ARRB2 drug opioid 28855588 These data suggest that inhibition of IPSCs by morphine involves a β arr2/c Src mediated mechanism.

ARRB2 drug opioid 22491351 Evidence that behavioral phenotypes of morphine in β arr2 / mice are due to the unmasking of JNK signaling. ARRB2 drug opioid 22491351 Using neurons lacking β arrestin 2 (β arr2 / ) to examine this interaction, we found that β arr2 / neurons show altered intracellular distribution of JNK and cJun, and that morphine, but not fentanyl, increased the nuclear localization of the phosphorylated, therefore activated, form of cJun, a JNK target in dorsal root ganglia neurons.

APEX1 drug alcohol 22126215 Free choice drinking demonstrated by the HAP1 and cHAP lines may provide a unique opportunity for modeling the excessive intake that often occurs in alcohol dependent individuals, and allow for exploration of predisposing factors for excessive consumption, as well as the development of physiological, behavioral and toxicological outcomes following alcohol exposure. APEX1 addiction dependence 21992190 The concentration dependence of ABCB4 appears to be a direct effect on transporter activity, as ABCB4 expression and ABCB4 plasma membrane (PM) localisation at the root apex are relatively insensitive to changes in auxin concentration. APEX1 drug alcohol 19120064 The high and low alcohol preferring (HAP1 and LAP1) mouse lines were selectively bred for differences in alcohol intake. APEX1 addiction reward 18214604 The present study examined Drd2 mRNA expression differences between the HAP1 and LAP1 mice in brain regions important in the dopaminergic reward pathway, including the nucleus accumbens, hippocampus, amygdala, and septum. APEX1 drug alcohol 18214604 Results show that alcohol naïve HAP1 mice exhibited lower levels of Drd2 mRNA expression in the nucleus accumbens and the hippocampus compared to LAP1 mice. APEX1 drug alcohol 17850641 The purpose of the present study was to examine whether acute alcohol withdrawal responses, as measured by acoustic startle and prepulse inhibition (PPI) of acoustic startle, may be genetically related to innate differences in alcohol preference in 2 mouse lines selectively bred for high (HAP1 and HAP2) or low (LAP1 and LAP2) alcohol preference.

APEX1 drug alcohol 17850641 Alcohol naive, male and female HAP1 (n = 35) and LAP1 (n = 32) and HAP2 (n = 43) and LAP2 (n = 40) mice were tested under baseline conditions and during withdrawal from a single injection of 4.0 g/kg alcohol or equal volume of saline at 4, 8, and 12 hours post injection. APEX1 addiction withdrawal 17850641 Alcohol naive, male and female HAP1 (n = 35) and LAP1 (n = 32) and HAP2 (n = 43) and LAP2 (n = 40) mice were tested under baseline conditions and during withdrawal from a single injection of 4.0 g/kg alcohol or equal volume of saline at 4, 8, and 12 hours post injection. APEX1 addiction withdrawal 17850641 In contrast, both HAP1 males and females showed a trend toward enhanced startle at 4 hours in withdrawal. ADM drug opioid 31960799 Initiation of glia neuron signaling networks in the peripheral and central nervous system by adrenomedullin is involved in the formation and maintenance of morphine tolerance. ADM addiction reward 29981631 The purpose of this review was to investigate outcomes in patients with abdominal wall hernia undergoing primary closure with component separation (CS) versus CS with acellular dermal matrix (ADM) reinforcement (CS + mesh). ADM addiction reward 29981631 Medical records of consecutive patients who underwent abdominal wall reconstruction using CS with or without ADM reinforcement were retrospectively reviewed. ADM addiction reward 29981631 ADM reinforcement when used was performed using the underlay technique. ADM addiction reward 29981631 ADM reinforcement at the time of components separation is often selected in more complex, higher risk patients. ADM addiction addiction 26597980 Addiction medicine (ADM) is an emerging medical field.

ADM addiction addiction 25814498 Tobacco cessation therapy is not consistently provided for alcohol, drug abuse and mental health (ADM) populations, despite the enormous health consequences of tobacco addiction in these groups and research supporting the effectiveness of treatment. ADM drug nicotine 25814498 Our goal was to determine whether popular reporting accurately reflects findings from the scientific literature on tobacco cessation treatment for ADM populations in treatment. ADM drug nicotine 25814498 Our results suggest that the failure to consistently provide tobacco cessation therapy to ADM populations in treatment is not due to poor research translation. ADM drug opioid 24132052 Half of the patients were scanned after/before daily methadone intake (ADM/BDM patient groups). ADM drug alcohol 21731413 PURPOSE: Stigma related feelings, including degree of enthusiasm and willingness to work with alcohol, drug, and mental disorder (ADM) patients, as well as anticipated success in such work, will be required for the United States to be successful in its new initiatives for ADM screening, brief intervention, and effective referral to treatment and rehabilitation services (SBIRT). ADM addiction addiction 21534129 In the United States accredited residency programs in addiction exist only for psychiatrists specializing in addiction psychiatry (ADP); nonpsychiatrists seeking training in addiction medicine (ADM) can train in nonaccredited "fellowships," or can receive training in some ADP programs, only to not be granted a certificate of completion of accredited training.

ADM drug alcohol 12236383 To compare adults with different insurance coverage in care for alcohol, drug abuse, and mental health (ADM) problems. ADM drug alcohol 11971152 BACKGROUND: In the United States, insurance benefits for treating alcohol, drug abuse and mental health (ADM) problems have been much more limited than medical care benefits. ADM drug alcohol 11810776 Transcatheter arterial chemo embolization (TACE, THP 30 60 mg, E ADM 20 40 mg, CDDP 40 80 mg, MMC 10 20 mg, iodine oil 5 30 ml), percutaneous ethanol injection (PEI), bioimmunotherapy and the traditional Chinese medicine were used pre and post operatively. ADM drug alcohol 11330001 This study estimates unmet need and barriers to alcohol, drug, and mental health (ADM) services in 1997 to 1998 using data from a national household survey (n = 9,585). ADM drug alcohol 11327191 We tested the hypothesis, stemming from the appraisal disruption model (ADM), that alcohol would be more likely to reduce stress when consumed prior to exposure to a stressor than when consumed following exposure. ADM drug alcohol 11327191 Findings were consistent with predictions stemming from the ADM. Alcohol appears to be more likely to reduce stress when initial stress appraisal occurs during intoxication. ADM addiction intoxication 11327191 Findings were consistent with predictions stemming from the ADM. Alcohol appears to be more likely to reduce stress when initial stress appraisal occurs during intoxication. ADM drug alcohol 10778825 We found that going to an EAP substantially increases both the probability of an alcohol, drug abuse, or mental health (ADM) claim and the number of ADM claims in the same quarter as EAP contact. ADM drug alcohol 10178432 What is the cost of ADM (alcohol and drug abuse and mental health) in the U.S.? ADM drug alcohol 7811346 The purpose of this microiontophoretic study was to explore GABAergic and cholinergic central mechanisms in adult rats exposed to alcohol in the third phase of prenatal life (ADM), when their mothers were subjected to alcohol physical dependence induction (9.6 g/kg/day). ADM addiction dependence 7811346 The purpose of this microiontophoretic study was to explore GABAergic and cholinergic central mechanisms in adult rats exposed to alcohol in the third phase of prenatal life (ADM), when their mothers were subjected to alcohol physical dependence induction (9.6 g/kg/day). ADM drug alcohol 7811346 alcohol injection (1.6 g/kg) spontaneous firing was depressed in ADM animals to a lesser extent than in C rats. ADM drug alcohol 10170864 Medicaid expenditures for alcohol, drug abuse, and mental health (ADM) services in 1984 were examined for the States of California and Michigan. ADM drug alcohol 2526093 This paper measures the cost of short stay hospitalization in 1985 for alcohol and drug abuse and mental illness (ADM). ADM drug alcohol 3533719 The question of psychiatry's role in medicine, and in particular its role in the training of primary care physicians (PCPs), is heightened by the knowledge that 60% of the 15% of patients who have DSM III diagnosable alcohol, drug abuse, and mental health (ADM) disorders are seen exclusively in the general health sector. ADM drug alcohol 390264 Although many of the studies suggested that alcohol, drug abuse or mental health (ADM) treatment was a cause of the subsequent reduction in medical care utilization, such causality was not definitively established, due to frequent methodological limitations, such as inadequate comparison groups, short time spans, small samples and lack of trend analysis.

SPINK5 drug cocaine 25619460 In the present study, we investigated the effects of a chronic cocaine treatment on molecular and structural plasticity in the cerebellum, including BDNF, D3 dopamine receptors, ΔFosB, the Glu2 AMPA receptor subunit, structural modifications in Purkinje neurons and, finally, the evaluation of perineuronal nets (PNNs) in the projection neurons of the medial nucleus, the output of the cerebellar vermis. SPINK5 drug nicotine 22579738 Many of the differences between carcinoids and high grade lung NETs can be ascribed to tobacco consumption, which is strongly linked to the occurrence of high grade NE carcinomas. SPINK5 drug cocaine 10411589 There were small but significant differences between the rat NET and the human or bovine NETs with respect to the affinities of sodium ions (greater for rat than for bovine) of the substrates norepinephrine, epinephrine, and 1 methyl 4 phenylpyridinium (greater for human than for rat), and of the inhibitor cocaine (greater for human and bovine than for rat), whereas the affinities of dopamine and of most inhibitors, including tricyclic antidepressants, showed no species differences. SPINK5 drug cocaine 10411589 The fact that the affinities for some substrates, cocaine and sodium ions exhibited small but significant interspecies differences among the rat, human, and bovine NETs suggests that ligand recognition, the translocation process, and sodium ion dependence are influenced differentially by just a few amino acid exchanges in the primary sequences of the transporters.

RAF1 drug opioid 32690613 Depolarization dependent C Raf signaling promotes hyperexcitability and reduces opioid sensitivity of isolated nociceptors after spinal cord injury. RAF1 drug opioid 32690613 Expression of an activated C Raf reduces sensitivity of adenylyl cyclase to opioids in non excitable HEK293 cells, while inhibition of C Raf or treatment with the hyperpolarizing drug retigabine restores opioid responsiveness and blocks spontaneous activity of nociceptors after SCI.

GRK2 drug opioid 30076211 Our studies identify an intracellular mechanism involving estradiol regulation of G protein coupled receptor kinase 2 that is responsible for sexually dimorphic analgesic responses following opioid receptor activation. GRK2 drug opioid 30018083 We have previously shown that high efficacy opioids such as DAMGO stimulate a GRK2/3 mediated multisite phosphorylation of conserved C terminal tail serine and threonine residues, which facilitates internalization of the receptor. GRK2 drug opioid 24517854 In fact, morphine induces a selective S375 phosphorylation that is predominantly catalysed by GPCR kinase 5 (GRK5), whereas multisite phosphorylation induced by high efficacy opioids specifically requires GRK2/3.

GABRA1 drug alcohol 29520058 We found that chronic ethanol exposure using either ethanol gavage or two bottle choice voluntary access paradigms decreased Gabra1 expression and increased Hdac2 and Hdac3 expression. GABRA1 drug alcohol 29520058 Administration of the HDAC inhibitor trichostatin A (TSA) after chronic ethanol exposure prevents the decrease in Gabra1 expression and function as well as the increase in Hdac2 and Hdac3 expression in both the cortex and the medial prefrontal cortex (mPFC).

GABRA1 drug alcohol 16792556 Association between GABRA1 and drinking behaviors in the collaborative study on the genetics of alcoholism sample. GABRA1 drug alcohol 16792556 In GABRA1, we found evidence of association with several of the drinking behavior phenotypes, including COGA alcohol dependence, history of blackouts, age at first drunkenness, and level of response to alcohol. GABRA1 addiction dependence 16792556 In GABRA1, we found evidence of association with several of the drinking behavior phenotypes, including COGA alcohol dependence, history of blackouts, age at first drunkenness, and level of response to alcohol. GABRA1 drug alcohol 16792556 We found evidence for association between GABRA1 and COGA alcohol dependence, history of blackouts, age at first drunkenness, and level of response to alcohol. GABRA1 addiction dependence 16792556 We found evidence for association between GABRA1 and COGA alcohol dependence, history of blackouts, age at first drunkenness, and level of response to alcohol. GABRA1 drug alcohol 15690551 Chromosome 5 contains a cluster of GABA(A) receptor genes, GABRA1, GABRA6, GABRB2, and GABRG2, which have been among the most extensively studied in relation to alcohol use. GABRA1 drug alcohol 12555233 Genes encoding GABRA1 and GABRA6, on chromosome 5, did not provide evidence for association with alcoholism. ERBB2 drug nicotine 31125062 In certain subgroups, PFS was positively associated with PD L1 expression (KRAS, EGFR) and with smoking status (BRAF, HER2). ERBB2 drug alcohol 30611309 Normally, 35% of breast cancer is Erb B2 Receptor Tyrosine Kinase 2 (ERBB2) positive that predisposes to poor prognosis and relapse, while ethanol drinking leads to invasion of their ERBB2 positive cells triggering the phosphorylation status of mitogen activated protein kinase.

ERBB2 drug alcohol 30611309 In this study, we demonstrate that ethanol administration promotes STARD10 and ERBB2 expression that is significantly associated with increased cell malignancy and aggressiveness. ERBB2 drug alcohol 30611309 We investigated the effect of ethanol on STARD10 ERBB2 cross talk in breast cancer cells, MMTV neu transgenic mice and in clinical ERBB2 positive breast cancer specimens with Western Blotting and Real time PCR. ERBB2 drug alcohol 30611309 Ethanol administration induces STARD10 and ERBB2 expression in vitro and in vivo. ERBB2 drug alcohol 30611309 Ethanol and STARD10 mediated cellular membrane fluidity and intracellular calcium concentration impact ERBB2 signaling pathway as evaluated by enhanced p65 nuclear translocation and binding to both ERBB2 and STARD10 promoters. ERBB2 drug alcohol 30611309 Taken together, our data demonstrate that ethanol can modulate ERBB2's function in breast cancer via a novel interplay with STARD10. ERBB2 drug alcohol 29774782 We have used phospho receptor tyrosine kinase (RTK) arrays to screen the impact of ethanol on TBI induced activation of RTK in somatosensory cortex, identifying ErbB2/ErbB3 among the RTKs activated by TBI and suppressed by ethanol. ERBB2 drug nicotine 28974261 Why are mutation rates in epidermal growth factor receptor (EGFR) and erb b2 receptor tyrosine kinase 2 (ERBB2) higher in lung cancer from never smokers than that from smokers? ERBB2 drug nicotine 28974261 Why are mutation rates in epidermal growth factor receptor (EGFR) and erb b2 receptor tyrosine kinase 2 (ERBB2) higher in lung cancer from never smokers than that from smokers? ERBB2 drug nicotine 27008586 Compared with the HER2 insertion negative group, patients with HER2 insertions were more likely to be never smokers (97.1 %, 34/35 patients, P < 0.001), significantly associated with female (91.4 %, 32/35 patients, P < 0.001), adenocarcinoma (91.4 %, 32/35 patients, P = 0.01), and with a tendency to be no more than 60 years of age (71.4 %, 25/35 patients, P = 0.051). ERBB2 drug opioid 25734987 Morphine does not facilitate breast cancer progression in two preclinical mouse models for human invasive lobular and HER2⁺ breast cancer. ERBB2 drug opioid 25734987 Using preclinical mouse models for metastatic invasive lobular and HER2 breast cancer, we show that analgesic doses of morphine do not affect mammary tumor growth, angiogenesis, and the composition of tumor infiltrating immune cells. ERBB2 addiction relapse 23775406 ANCCA expression was evaluated by immunohistochemistry in 143 surgically resected lung adenocarcinomas and was correlated with clinicopathologic and molecular variables including adenocarcinoma histologic subtypes, tumor, node, metastasis status, relapse free survival, overall survival, EGFR mutations, KRAS mutations, HER2 mutations and ALK fusions. ERBB2 drug nicotine 21655907 In addition, most adenocarcinomas in never smokers harbor one of the proto oncogene aberrations that occur in a mutually exclusive manner (EGFR mutation, KRAS mutation, HER2 mutations, or ALK translocation). ERBB2 drug cannabinoid 20649976 Cannabinoids reduce ErbB2 driven breast cancer progression through Akt inhibition. ERBB2 addiction relapse 20649976 Although specific ErbB2 targeted therapies have been designed, only a small percentage of patients respond to these treatments and most of them eventually relapse. ERBB2 drug cannabinoid 20649976 The purpose of this study was to determine whether cannabinoids might constitute a new therapeutic tool for the treatment of ErbB2 positive breast tumors. ERBB2 drug cannabinoid 20649976 We also found that 91% of ErbB2 positive tumors express the non psychotropic cannabinoid receptor CB2. ERBB2 drug cannabinoid 20649976 Taken together, these results provide a strong preclinical evidence for the use of cannabinoid based therapies for the management of ErbB2 positive breast cancer. ERBB2 drug nicotine 18705409 Statistically significant associations between high Ki67 and poorly differentiated tumors (P = 0.016) and a smoking history (P = 0.053); p53 positivity and high Ki67 (P = 0.002); HER 2 positivity and adenocarcinoma subtype (P = 0.015) and presence of lymph node involvement (P = 0.006); and Bcl 2 positivity and squamous cell carcinoma subtype (P = 0.058) were observed. DUSP26 addiction withdrawal 27618597 Similarly, in the paw withdrawal test, this substance generated a strong analgesic effect (with over 200% of analgesia) in the control group, whereas its action in the rats with DSP 4 lesions was statistically significant. DUSP26 drug alcohol 26549324 While degeneration [N (2 chloroethyl) N ethyl 2 bromobenzylamine hydrochloride, DSP 4, intraperitoneal route] or silencing (lidocaine or muscimol, both via intra LC route) of the LC noradrenergic neurons decreased, phenylephrine via the intra LC route reinstated ethanol self administration. DUSP26 drug alcohol 26549324 Ethanol self administration significantly increased tyrosine hydroxylase immunoreactivity in pVTA and LC; the response was blocked by DSP 4 pre treatment. DUSP26 addiction dependence 25601230 DSP 4 treated SD rats demonstrated a dependence like phenotype, whereas WKY rats were unchanged. DUSP26 drug cocaine 20678524 The effect of denervation of the locus coeruleus projections with N (2 chloroethyl) N ethyl 2 bromobenzylamine (DSP 4) on cocaine induced locomotion and place preference in rats. DUSP26 drug cocaine 20678524 The potential contribution of locus coeruleus (LC) derived noradrenaline (NA) in the motor activating and rewarding effects of cocaine (15 mg/kg) were assessed following administration of the neurotoxin N (2 chloroethyl) N ethyl 2 bromobenzylamine (DSP 4). DUSP26 drug cocaine 20678524 In Experiment 1, administration of 10 mg/kg of DSP 4 similarly to substantial denervation with 50 mg/kg of DSP 4 significantly attenuated the activating effects of cocaine during the first cocaine paired training session (30 min) in the conditioned place preference (CPP) apparatus. DUSP26 addiction reward 20678524 In Experiment 1, administration of 10 mg/kg of DSP 4 similarly to substantial denervation with 50 mg/kg of DSP 4 significantly attenuated the activating effects of cocaine during the first cocaine paired training session (30 min) in the conditioned place preference (CPP) apparatus. DUSP26 drug cocaine 20678524 Cocaine CPP as measured by increment of time spent in the previously cocaine paired chamber during drug free conditions before and after cocaine paired trainings was clearly revealed only in animals with intact projections from the LC, and was entirely absent after a large lesion of LC projections by DSP 4 (50 mg/kg). DUSP26 addiction reward 20678524 Cocaine CPP as measured by increment of time spent in the previously cocaine paired chamber during drug free conditions before and after cocaine paired trainings was clearly revealed only in animals with intact projections from the LC, and was entirely absent after a large lesion of LC projections by DSP 4 (50 mg/kg). DUSP26 drug cocaine 20678524 Because recovery of noradrenaline levels by the end of experiment did not allow assessment of the efficacy of the neurotoxin, the effect of DSP 4 pre treatment on the acute psychomotor effect of cocaine was re examined in an independent experiment (Experiment 2). DUSP26 drug cocaine 20678524 Near complete denervation of the LC projections again reduced the effect of cocaine, but the lower dose of DSP 4 had no effect, suggesting that small lesions of the LC do not have a robust impact. DUSP26 drug psychedelics 20002520 Experiment 1 investigated MDMA induced changes in levels of the serotonin transporter (SERT) and the vesicular monoamine transporter 2 (VMAT 2) in the hippocampus, a region with sparse dopaminergic innervation, after lesioning noradrenergic input with N (2 chloroethyl) N ethyl 2 bromobenzylamine (DSP 4). DUSP26 drug psychedelics 20002520 Adult male Sprague Dawley rats were administered 100 mg/kg DSP 4 or saline 1 week prior to either an MDMA (10 mg/kg x 4) or saline binge. DUSP26 addiction intoxication 20002520 Adult male Sprague Dawley rats were administered 100 mg/kg DSP 4 or saline 1 week prior to either an MDMA (10 mg/kg x 4) or saline binge. DUSP26 drug psychedelics 20002520 Two weeks following the binge treatment, the DSP 4/MDMA group unexpectedly showed little change in hippocampal VMAT 2 protein expression compared with DSP 4/Saline controls, despite large reductions in SERT levels in all regions examined in the MDMA treated animals. DUSP26 addiction intoxication 20002520 Two weeks following the binge treatment, the DSP 4/MDMA group unexpectedly showed little change in hippocampal VMAT 2 protein expression compared with DSP 4/Saline controls, despite large reductions in SERT levels in all regions examined in the MDMA treated animals. DUSP26 drug amphetamine 17156751 In the present study the amphetamine induced locomotor activity and behavioral sensitization to amphetamine (0.5 mg/kg) was investigated in rats with high or low spontaneous exploratory activity (HE and LE rats, respectively) after partial denervation of the locus coeruleus (LC) projections with a low dose of the selective neurotoxin DSP 4 (N (2 chloroethyl) N ethyl 2 bromobenzylamine; 10 mg/kg). DUSP26 addiction sensitization 17156751 In the present study the amphetamine induced locomotor activity and behavioral sensitization to amphetamine (0.5 mg/kg) was investigated in rats with high or low spontaneous exploratory activity (HE and LE rats, respectively) after partial denervation of the locus coeruleus (LC) projections with a low dose of the selective neurotoxin DSP 4 (N (2 chloroethyl) N ethyl 2 bromobenzylamine; 10 mg/kg). DUSP26 drug amphetamine 17156751 Amphetamine stimulated locomotor activity was attenuated by the DSP 4 pretreatment only in the HE rats and this effect persisted over repeated testing. DUSP26 addiction withdrawal 15781512 Depletion of systemic norepinephrine with the neurotoxin DSP 4 caused a reduction in baseline withdrawal latencies and prevented isoflurane pronociception. DUSP26 drug opioid 14715456 Effects of alpha adrenoceptor agonists in chronic morphine administered DSP4 treated rats: evidence for functional cross sensitization. DUSP26 addiction sensitization 14715456 Effects of alpha adrenoceptor agonists in chronic morphine administered DSP4 treated rats: evidence for functional cross sensitization. DUSP26 drug opioid 14715456 Five experiments were performed to study the effects of the Alpha adrenoceptor agonists, clonidine and guanfacine, upon spontaneous motor activity in chronically morphine administered DSP4 treated and control rats. DUSP26 drug opioid 14715456 DSP4 pretreatment and chronic morphine injections each reduced motor activity during the first 30 min of testing; combined DSP4 and morphine treatment potentiated the hypoactivity. DUSP26 drug opioid 14715456 Habituation quotients indicated deficits in habituation to the novel test environment by the Vehicle morphine (Quoteint2 only) and DSP4 morphine groups. DUSP26 drug opioid 14715456 Acute clonidine treatment (0.04 mg/kg s.c.) reduced motor activity during the first 30 min of testing but attenuated or blocked the morphine induced hypoactivity in DSP4 treated and control rats. DUSP26 drug opioid 14715456 During the 60 90 min test period, clonidine, but not guanfacine (0.08 mg/kg), potentiated morphine induced hyperactivity in control rats; acute clonidine enhanced this effect, whereas acute guanfacine reduced it, in the DSP4 treated rats. DUSP26 drug opioid 14715456 Naloxone (0.1 mg/kg s.c.), injected after the 1st 30 min of testing, potentiated markely the clonidine induced elevations of motor activity in morphine administered control rats; in the DSP4 treated rats, these effects were dramatically potentiated, underlining the cross sensitivity effect. DUSP26 drug opioid 14715456 Acute guanfacine treatment reduced motor activity during the first 30 min of testing but did not attenuate reliably morphine induced hypoactivity in control or DSP4 rats. DUSP26 drug opioid 14715456 Naloxone did not potentiate the guanfacine induced hyperactivity of morphine administered control rats but induced a marked enhancement in the DSP4 treated rats, a specific case of cross reactivity. DUSP26 drug opioid 14715456 The major findings pertain to a cross sensitization effect of morphine upon clonidine induced motor activity in both DSP4 treated and control rats, and to a lesser extent between morphine and guanfacine in NA denervated rats only.

DUSP26 addiction withdrawal 7509021 Treatment with DSP 4 before the naloxone challenge suppressed the expression of morphine withdrawal signs, including jumping and "wet dog" shakes. DUSP26 drug cocaine 2070264 Such potentiating effects of cocaine on GABA mediated inhibition were not evident in animals pretreated with the selective noradrenergic toxins DSP 4. DUSP26 drug benzodiazepine 3126522 Depletion of central noradrenaline produced by systemic injections of DSP4 did not affect diazepam induced place preference conditioning. DUSP26 drug amphetamine 3110849 DSP4 alters the effect of d amphetamine on variable interval performance: analysis in terms of Herrnstein's equation. DUSP26 drug amphetamine 3110849 The effect of d amphetamine (0.1 3.2 mg/kg) on performance in variable interval 1 min and variable interval 12 min schedules of positive reinforcement was examined in ten rats treated with the selective noradrenaline neurotoxin DSP4 and 12 control rats. DUSP26 addiction reward 3110849 The effect of d amphetamine (0.1 3.2 mg/kg) on performance in variable interval 1 min and variable interval 12 min schedules of positive reinforcement was examined in ten rats treated with the selective noradrenaline neurotoxin DSP4 and 12 control rats. DUSP26 drug amphetamine 3110849 In the case of both schedules, lower doses of d amphetamine were more suppressant and higher doses less suppressant in the DSP4 treated group than in the control group. DUSP26 drug amphetamine 3110849 The results indicate that treatment with DSP4 attenuated both the facilitatory and the suppressant effects of d amphetamine on variable interval performance.

CPZ drug benzodiazepine 2187002 Four mg chlorpromazine (CPZ) was administered every hour and 10 mg diazepam (DIA) every 6 hours to a group consisting of two female and nineteen male inpatients. CPZ drug opioid 2187002 The remaining subjects received 15 mg non opioid antitussive dextromethorphan (DM) instead of CPZ. CPZ drug benzodiazepine 2540276 Daily intraperitoneal administration to rats of 5 mg/kg of chlorpromazine (CPZ) for 21 days induced a significant up regulation (51%) of peripheral benzodiazepine binding sites (PBSs) in cerebral cortex and a down regulation of PBSs in the heart (25%) and kidney (14%), whereas no alteration in [3H]flunitrazepam binding in cerebral cortex was observed. CPZ addiction withdrawal 2540276 [3H]PK 11195 binding to cerebral cortex returned to normal following 5 days of CPZ withdrawal, whereas the density of PBSs in the heart and kidney remained reduced. CPZ drug amphetamine 2496967 In addition, provocative pharmacologic challenges were employed to assess the interaction between A23187 and the centrally active drugs amphetamine (AMPH), scopolamine (SCOP), or chlorpromazine (CPZ). CPZ drug amphetamine 2496967 In the pharmacological challenge studies, AMPH and SCOP both attenuated and CPZ enhanced the acute hypomotility induced by 0.5 mg A23187/kg. CPZ drug benzodiazepine 6151209 Acute drug effects on the three dependent variables were assessed for dose ranges of haloperidol (HAL), chlorpromazine (CPZ), clozapine (CLZ), and chlordiazepoxide (CDP). CPZ drug benzodiazepine 6415749 Food presentation or cocaine injection occurred only at the end of each daily session, thereby allowing assessment of the effects of presession administration of cocaine, chlorpromazine (CPZ), and chlordiazepoxide (CDP) on responding at times when the direct effects of consequent cocaine injections were minimal or absent. CPZ drug cocaine 6415749 Food presentation or cocaine injection occurred only at the end of each daily session, thereby allowing assessment of the effects of presession administration of cocaine, chlorpromazine (CPZ), and chlordiazepoxide (CDP) on responding at times when the direct effects of consequent cocaine injections were minimal or absent. CPZ drug cocaine 6415749 Presession treatment with suitable doses of cocaine increased low rates of food or cocaine maintained responding under both types of second order schedules, whereas CPZ only decreased responding. CPZ drug cocaine 6415749 Thus, the behavioral effects of cocaine, CDP, and CPZ were largely independent of whether responding was maintained by food or by cocaine. CPZ drug benzodiazepine 6177889 The B dependent rats were grouped according to the following 5 states: G I, B dependent state; G II, B withdrawn state; G III, cross administration of nitrazepam (NZP) following B withdrawal; G IV, cross administration of chlorpromazine (CPZ) following B withdrawal; and G V, cross administration of phenytoin following B withdrawal.

CPZ addiction withdrawal 6177889 On the other hand, CPZ and phenytoin, which inhibit B withdrawal convulsion slightly, failed to recover completely the 5 HT turnover rate during B withdrawal. CPZ drug benzodiazepine 6118452 In the crossphysical dependence study, two drug combinations, i.e., phenobarbital (PhB) chloropromazine (CPZ), PhB diphenhydramine (DPH) and nitrazepam chlorprothixene, and 3 drug combinations (i.e., PhB CPZ promethazine and PhB CPZ DPH were evaluated.

CPZ addiction reward 7297414 Chlorpromazine (CPZ) and haloperidol (H) have been suggested as possible antagonists of the reinforcing effects of psychomotor stimulant drugs. CPZ drug cocaine 7297414 Continuous infusions of low or intermediate doses of CPZ or H either did not affect or increased the frequency of cocaine choice. CPZ drug cocaine 7297414 Although ther appears to be a mutual antagonism of some of the effects of cocaine and these antipsychotic compounds, the results of the present experiment fail to support the hypothesis that the reinforcing effects of cocaine can be antagonized with CPZ or H.

CPZ drug benzodiazepine 32386 Jumping was exacerbated by CPZ (4 mg/kg), chlordiazepoxide (4 and 8 mg/kg) and DPM (1, 2 and 4 mg/kg); haloperidol and thioridazine had no significant effect on this sign. CPZ addiction reward 825884 Chlorpromazine (CPZ) doses of 0.5 and 1.0 mg/kg decreased caudate ICSS significantly more than lateral hypothalamic ICSS.

CPZ drug benzodiazepine 169190 The effect of chlorpromazine (CPZ), imipramine (IMP), nitrazepam (NZP) and amobarbital sodium (AMOB) on the REM period of sleep (REMP) was investigated on four subjects by means of all night sleep polygraphy with the schedule PPPDDDPP where P is placebo and D active drug. CPZ addiction withdrawal 169190 CPZ 25 mg resulted in a slight increase in %REMP, and no significant change in REM density (1 second fraction method) and total REM activity during the drug and withdrawal nights. CPZ drug psychedelics 13739950 A representative psychotogen, lysergic acid diethylamide (LSD 25), in doses small enough to be devoid of gross effects, increases response latency in rats to a tone indicating the availability of water reward; this effect is greatly reduced by prophylactic administration of a representative phenothiazine tranquilizer, chlorpromazine (CPZ), in doses that per se do not affect performance.

CCR5 drug cocaine 31557508 Chemokine CCR5 and cocaine interactions in the brain: Cocaine enhances mesolimbic CCR5 mRNA levels and produces place preference and locomotor activation that are reduced by a CCR5 antagonist. CCR5 drug cocaine 31557508 Evidence that CCR5 knockout mice display fewer dopamine neurons, lower striatal dopamine levels, and reduced locomotor activation compared to wild types also suggest a link between CCR5 receptors and cocaine dependence.

CCR5 drug cocaine 31557508 In rats treated repeatedly with cocaine (10 mg/kg × 4 days, IP), CCR5 gene expression was upregulated in the nucleus accumbens and ventral tegmental area but mRNA levels of CCR5 ligands (i.e., CCL3, CCL4 and CCL5) were not affected. CCR5 drug cocaine 31557508 Our results suggest that mesolimbic CCR5 receptors are dysregulated by cocaine exposure and, similar to CXCR4 and CCR2 receptors, influence behavioral effects related to the abuse liability of cocaine. CCR5 addiction intoxication 31265902 The binge group showed increased expression of CCR5 and PD 1 in NKCs, respective to the LR group, and decreased expression of TLR4, along with fewer CCR4+ cells. CCR5 drug opioid 30970233 MCC22 consists of mu opioid receptor (MOR) agonist and chemokine receptor 5 (CCR5) antagonist pharmacophores connected through a 22 atom spacer and was designed to target a putative MOR CCR5 heteromer localized in pain processing areas.

CCR5 drug opioid 29146238 These effects may involve the C C chemokine receptor type 5 (CCR5); however, the behavioral contribution of CCR5 on Tat/opioid interactions is not known. CCR5 drug opioid 29146238 To assess the influence of CCR5 on these effects, mice were pretreated with oral vehicle or the CCR5 antagonist, maraviroc, prior to morphine administration. CCR5 drug opioid 29146238 Protein array analyses revealed only minor changes to cytokine profiles when morphine was administered acutely or repeatedly; however, 24 h post morphine administration, the expression of several cytokines was greatly increased, including endogenous CCR5 chemokine ligands (CCL3, CCL4, and CCL5), as well as CCL2. CCR5 drug opioid 29146238 These data demonstrate that CCR5 mediates key aspects of HIV 1 Tat induced alterations in the antinociceptive potency and rewarding properties of opioids. CCR5 addiction intoxication 28481655 Compared to the low risk group, the binge group showed higher CCR5 expression on PMNs, decreases in the CD69 percentage and positive PMNs per microliter, and decreased CXCR4 expression on monocytes.

SLC1A1 drug amphetamine 31912366 Since AMPH is a transported inhibitor of both DAT and the norepinephrine transporter (NET), and EAAT3 is also expressed in norepinephrine (NE) neurons, we explored the possibility that this signaling cascade occurs in NE neurons. SLC1A1 drug amphetamine 31912366 We found that AMPH can cause endocytosis of NET as well as EAAT3 in NE neurons. SLC1A1 addiction dependence 31912366 However, EAAT3 endocytosis is similar in all regards except its dependence upon CaMKII activation. SLC1A1 drug amphetamine 31912366 RhoA activation is dependent on calcium, but not CaMKII, explaining a divergence in AMPH mediated endocytosis of DAT and NET from that of EAAT3. SLC1A1 addiction withdrawal 30267744 Likewise, mice receiving the MA withdrawal regimen had high expression in mGluR5 protein but unaltered EAAT3, Homer2 expression in hippocampal tissues.

SLC1A1 drug amphetamine 28927446 To evaluate the impact of reduced EAAT3 expression in vivo, we studied male EAAT3 heterozygous and wild type littermate mice using a battery of behavioral paradigms relevant to anxiety (open field test, elevated plus maze) and compulsivity (marble burying), as well as locomotor activity induced by amphetamine. SLC1A1 addiction addiction 28927446 Compared to wild type littermates, EAAT3 heterozygous male mice have unaltered baseline anxiety like, compulsive like behavior and locomotor activity. SLC1A1 addiction addiction 28927446 Our results indicate that reduced EAAT3 expression does not impact neurotransmitter content in the corticostriatal circuit nor alter anxiety or compulsive like behaviors. SLC1A1 drug amphetamine 28507136 Using amphetamine as a probe, we found that EAAT3 loss prevents expected increases in (i) locomotor activity, (ii) stereotypy, and (iii) immediate early gene induction in the dorsal striatum following amphetamine administration.

SLC1A1 drug opioid 28049029 A small dose of morphine similarly reinstated the conditioned behavior in the wild type and EAAT3 / mice. SLC1A1 drug opioid 28049029 Morphine increased EAAT3 expression in the plasma membrane of medial prefrontal cortex, nucleus accumbens and ventral tegmental area but did not affect EAAT3 expression in the hippocampus.

SLC1A1 addiction withdrawal 26569416 EAAT2 and EAAT3 expressions in the patients during both early and late withdrawal were higher than those of the controls. SLC1A1 drug alcohol 26569416 The study revealed an upregulation of glutamate transporters EAAT2 and EAAT3 during early and late withdrawal in patients with alcohol withdrawal. SLC1A1 addiction withdrawal 26569416 The study revealed an upregulation of glutamate transporters EAAT2 and EAAT3 during early and late withdrawal in patients with alcohol withdrawal. SLC1A1 drug opioid 25839761 Chronic exposure to morphine decreases the expression of EAAT3 via opioid receptors in hippocampal neurons. SLC1A1 drug opioid 25839761 In this study, we used primary cultures of hippocampal neurons from neonatal rats to study the effects of chronic exposure to morphine on excitatory amino acid transporter 3 (EAAT3) expression and the roles of µ opioid receptor (MOR), δ opioid receptor (DOR), and κ opioid receptor (KOR) in the morphine dependent alterations in EAAT3 expression. SLC1A1 drug opioid 25839761 The results showed that the EAAT3 protein and mRNA expression levels decreased significantly after chronic exposure to morphine (10μmol/L) for 48h, whereas the concentration of extracellular glutamate increased. SLC1A1 drug opioid 25839761 In addition, we found that both the MOR inhibitor CTOP and the DOR inhibitor naltrindole could reverse the decreased expression of EAAT3 after exposure to morphine, whereas the MOR activator DAMGO and the DOR activator DPDPE significantly decreased EAAT3 expression. SLC1A1 drug opioid 25839761 These results suggest that the down regulation of morphine dependent EAAT3 expression in primary rat hippocampal cultures may be mediated by MOR and DOR and that KOR may not contribute significantly to this effect. SLC1A1 drug alcohol 25743187 In the medial prefrontal cortex, 2.5g/kg ethanol decreased mRNA expression of brain derived neurotrophic factor, NMDA NR2A subunit, mGluR8 receptor, Homer1, the glutamate transporters SLC1a1 and SLC1a6 and Srr. SLC1A1 drug opioid 24120272 Altered δ opioid receptor (DOR) activity can affect the activity and function of excitatory amino acid transporter 3 (EAAT3), but the effects of DOR on EAAT3 expression in morphine relapse remain unknown. SLC1A1 addiction relapse 24120272 Altered δ opioid receptor (DOR) activity can affect the activity and function of excitatory amino acid transporter 3 (EAAT3), but the effects of DOR on EAAT3 expression in morphine relapse remain unknown. SLC1A1 drug opioid 24120272 Here, we show that EAAT3 protein levels in C6δ cells decreased significantly after chronic exposure to morphine (10 μM) for 48 h and returned to normal 12 h after drug withdrawal. SLC1A1 addiction withdrawal 24120272 Here, we show that EAAT3 protein levels in C6δ cells decreased significantly after chronic exposure to morphine (10 μM) for 48 h and returned to normal 12 h after drug withdrawal. SLC1A1 drug opioid 24120272 When C6δ cells were re exposed to 5 μM morphine for 4 h, EAAT3 protein levels again decreased significantly. SLC1A1 drug opioid 24120272 The selective μ opioid receptor (MOR) specific agonist DAMGO had a similar effect as morphine, and CTOP, a specific MOR blocker, reversed the declined expression of EAAT3 protein triggered by morphine exposure. SLC1A1 drug opioid 24120272 The selective DOR agonist [d pen2, 5] enkephalin (DPDPE) significantly increased EAAT3 expression in C6δ cells and even reversed the decreased EAAT3 expression caused by chronic morphine exposure. SLC1A1 drug opioid 24120272 The non specific antagonist naloxone, but not the DOR inhibitor Naltrindole (NTI), reversed the decreased EAAT3 expression in C6δ cells caused by chronic morphine exposure. SLC1A1 drug opioid 24120272 In vivo, EAAT3 levels in the prefrontal cortex of rats with morphine induced CPP reinstatement significantly decreased.

SLC1A1 addiction reward 24120272 In vivo, EAAT3 levels in the prefrontal cortex of rats with morphine induced CPP reinstatement significantly decreased. SLC1A1 drug opioid 24120272 Naloxone completely suppressed reinstatement and reversed the decrease in EAAT3 expression induced by morphine re exposure. SLC1A1 addiction relapse 24120272 Naloxone completely suppressed reinstatement and reversed the decrease in EAAT3 expression induced by morphine re exposure. SLC1A1 addiction relapse 24120272 In contrast, NTI only weakened CPP reinstatement and exerted no influence on EAAT3 expression. SLC1A1 addiction reward 24120272 In contrast, NTI only weakened CPP reinstatement and exerted no influence on EAAT3 expression. SLC1A1 drug opioid 24120272 However, the morphine induced down regulation of EAAT3 in C6δ cells and in the prefrontal cortex of rats may not be mediated by DOR. SLC1A1 drug amphetamine 22540959 Changes in the neuronal glutamate transporter EAAT3 in rat brain after exposure to methamphetamine. SLC1A1 drug amphetamine 22540959 Therefore, this study examined the effects of acute and sub acute METH administration on the expression of the EAAT3 in the hippocampal formation, striatum and frontal cortex. SLC1A1 drug amphetamine 22540959 A significant increase in EAAT3 was found in the hippocampal formation after sub acute, but not acute, METH administration. SLC1A1 drug amphetamine 22540959 Our results of decreased EAAT3 in striatum and frontal cortex suggest deficits of cortico striatal glutamatergic synapses after METH exposure. SLC1A1 drug amphetamine 22540959 Increased EAAT3 expression in the hippocampus may be a compensatory response to possible deficits of glutamatergic neurotransmission induced by METH. SLC1A1 drug cannabinoid 15509898 Prenatal cannabinoid exposure down regulates glutamate transporter expressions (GLAST and EAAC1) in the rat cerebellum. SLC1A1 drug cannabinoid 15509898 This study analyzed the expression of the glial (GLAST) and neuronal (EAAC1) subtypes of glutamate transporter in the cerebellum of male and female offspring exposed pre and postnatally to Delta9 tetrahydrocannabinol (THC, the main component of marijuana). SLC1A1 drug cannabinoid 15509898 The expression of the glutamate transporter GLAST in astroglial cells and EAAC1 in Purkinje neurons decreased in THC exposed offspring compared to controls. SLC1A1 drug opioid 12805317 Cell surface biotinylation and immunoblot analysis showed that morphine withdrawal produced an increase in GLT1 expression rather than EAAC1 (excitatory amino acids carrier 1), a neuronal subtype, at the cultured neuronal cell surface, whereas no significant change was observed in that of cultured astrocytes. SLC1A1 addiction withdrawal 12805317 Cell surface biotinylation and immunoblot analysis showed that morphine withdrawal produced an increase in GLT1 expression rather than EAAC1 (excitatory amino acids carrier 1), a neuronal subtype, at the cultured neuronal cell surface, whereas no significant change was observed in that of cultured astrocytes. SLC1A1 drug amphetamine 11406296 Amphetamine administration does not alter protein levels of the GLT 1 and EAAC1 glutamate transporter subtypes in rat midbrain, nucleus accumbens, striatum, or prefrontal cortex. SLC1A1 drug amphetamine 11406296 The goal of this study was to determine whether repeated amphetamine administration influences the expression of two glutamate transporter subtypes, GLT 1 and EAAC1. SLC1A1 drug amphetamine 11406296 We found no significant change in levels of GLT 1 or EAAC1 in response to either acute or chronic amphetamine treatment.

S100B drug alcohol 31533168 Therefore, the present study aims to investigate the relationship between the blood ethyl alcohol concentration and the S100B serum concentration in an experimental setting in young human adult volunteers. S100B drug alcohol 31533168 In a cohort of 58 healthy volunteers, serum S100B concentration and blood ethyl alcohol concentration were measured before and after liberately drinking alcohol. S100B drug alcohol 31533168 The S100B value ranged from to 0,021 to 0,115 µg/l after alcohol consumption (S100B standard value < 0,11 µg/l). S100B drug alcohol 31533168 By calculating the Pearson correlation of empirical correlation after drinking alcohol with r = 0.01181, a correlation between serum S100B concentration and ethyl alcohol concentration is not probable. S100B drug alcohol 31533168 The S100B concentrations were independent on the alcohol intake in low to medium alcohol levels. S100B drug alcohol 31533168 A relevant alcohol blood concentration (~ 1 g/l), in otherwise healthy volunteers, does not affect the serum concentration of S100B. S100B drug benzodiazepine 31022077 Using an animal model, we investigated serum S100b as an acute biomarker of cerebral hypoperfusion and cerebral cell dysfunction during hypotension, hypocapnia, or combined hypotension/hypocapnia during GA. Fifty seven sevoflurane midazolam anesthetized piglets aged 4 to 6 weeks were randomly allocated to control (n=9), hypotension (n=18), hypocapnia (n=20), or combined hypotension and hypocapnia (n=10). S100B drug opioid 28750172 Transgenerational modification of hippocampus TNF α and S100B levels in the offspring of rats chronically exposed to morphine during adolescence. S100B drug opioid 28750172 We examined the consequences of chronic morphine consumption by parents before mating on hippocampus TNF α and S100B levels in the parents and their offspring. S100B drug opioid 28750172 Hippocampus levels of S100B were significantly decreased in male (P < 0.05) but not female morphine consumer parents relative to control parents. S100B drug opioid 28750172 Both male and female offspring of morphine exposed parents showed significant decreases in hippocampus S100B levels (P < 0.05) compared to those of control offspring. S100B drug alcohol 24786333 S100B protein was increased in the cerebrospinal fluid (CSF) in the group treated with alcohol, and alterations in GFAP expression were also shown.

S100B addiction intoxication 21897336 The influence of experimental alcohol load and alcohol intoxication on S100B concentrations. S100B drug alcohol 21897336 However, whether S100B levels are influenced by alcohol itself remains to be unclear. S100B drug alcohol 21897336 Therefore, we performed a case control study of nontraumatized, alcohol intoxicated patients to prove if serum S100B is altered by alcohol uptake. S100B drug alcohol 21897336 Furthermore, we investigated if alcohol infusions combined with an initial oral alcohol load up to a blood alcohol steady state of 100 mg/dL affected S100B levels in healthy volunteers (n = 12). S100B drug alcohol 21897336 In contrast, compared with the control group (n = 60 sober and healthy), the ethyl alcohol intoxicated patients (n = 61; mean ethyl alcohol, 251 [SD, 87] mg/dL) had higher S100B concentrations (0.193 [SD, 0.45] vs. 0.063 [SD, 0.059] μg/L; P < 0.001), and 39% of them had levels greater than the pathologic cutoff at greater than 0.104 μg/L. S100B drug alcohol 21897336 However, no significant correlation was found between ethyl alcohol concentrations and S100B within the respective group. S100B drug alcohol 21897336 Our clinical data suggest that blood alcohol concentrations far in excess of 100 mg/dL are associated with increased S100B levels in alcohol intoxicated patients.

S100B drug alcohol 20016383 Although there seems to be a strong association between S100B levels and TBI, further research is required to establish the clinical role of S100B in patients with suspected TBI, particularly in patients whose clinical presentation is complicated by alcohol intoxication.

S100B addiction intoxication 18812013 S100B overexpressing mutant mice exhibit prolonged behavioural and biochemical responses towards repeated intermittent binge treatments with MDMA. S100B drug psychedelics 18812013 Repeated binge treatment with MDMA (5 mg/kg, 3 times daily, 3 h apart, once per week for 4 wk) was found to increase gene expression of S100B, a neurotrophic factor that modulates neuronal plasticity. S100B addiction intoxication 18812013 Repeated binge treatment with MDMA (5 mg/kg, 3 times daily, 3 h apart, once per week for 4 wk) was found to increase gene expression of S100B, a neurotrophic factor that modulates neuronal plasticity. S100B drug psychedelics 18812013 Mutant mice overexpressing S100B were investigated to better understand how increased S100B expression may influence MDMA induced biochemical and behavioural responses. S100B drug psychedelics 18812013 In open field behaviour, the later MDMA binges decreased rearing and thigmotaxis in S100B mutant mice compared to wild type mice. S100B drug psychedelics 18812013 In the elevated plus maze, MDMA increased open arm entries in both genotypes, but less tolerance to this effect was found in S100B mutant mice. S100B drug psychedelics 18812013 MDMA treatment increased SERT in wild type mice, but did not further increase it in S100B mutant mice. S100B drug psychedelics 18812013 5 HT1B receptor density and G protein coupling were higher in MDMA treated S100B mutant mice than in saline treated mutant mice and MDMA treated wild type mice in the medial globus pallidus. S100B drug psychedelics 18812013 In conclusion, repeated MDMA treatment increases S100B mRNA. S100B drug psychedelics 18812013 Certain explorative and anxiolytic like behaviours in response to MDMA are potentiated and exhibit less tolerance in mice overexpressing S100B. S100B drug psychedelics 18812013 Our data indicate that genetic differences in S100B gene expression may predispose individual differences in the responsivity to repeated intake of MDMA. S100B drug psychedelics 17880365 In the present study, we investigated the effect of anaesthetics (thiopental, ketamine and halothane) on CSF concentrations of S100B, as well as a possible sex dependence, because several studies have suggested astrocytes as putative targets for oestrogen. S100B addiction dependence 17880365 In the present study, we investigated the effect of anaesthetics (thiopental, ketamine and halothane) on CSF concentrations of S100B, as well as a possible sex dependence, because several studies have suggested astrocytes as putative targets for oestrogen. S100B addiction dependence 17880365 Assuming CSF S100B as a marker of development, glial activation or even brain damage, investigations regarding the sex dependence of its concentration may be useful in gaining an understanding of sex variations in the behaviour and the pathological course of, as well as susceptibility to, many brain disorders. S100B addiction dependence 17880365 The findings of the present study reinforce the sex effect on synaptic plasticity and suggest a sex dependence of neural communication mediated by extracellular S100B without restricting the influence of astrocytes on the developmental phase. S100B drug alcohol 17091777 Serum levels of S100B protein have been extensively studied in several conditions of neural tissue injury but not in alcohol abuse. S100B drug alcohol 17091777 The aim of this study was to evaluate the serum levels of S100B in alcohol dependent individuals and to further investigate the effect of alcohol detoxification on the levels of S100B. S100B drug alcohol 17091777 The S100 B levels decreased in 10 patients with a moderate alcohol consumption over the last year, but increased in 10 patients with high alcohol consumption over the last year. S100B drug alcohol 17091777 S100B protein levels are affected differently in alcohol dependent individuals with either mild or high alcohol consumption during the period of up to one year before assessment. S100B drug alcohol 17091777 Although this is a preliminary study, the present data suggest a possible use of S100B protein measurements in detecting alcohol dependent individuals with high alcohol consumption and in further monitoring the alcohol detoxification treatment.

PTN drug alcohol 31054277 The data presented here demonstrate for the first time that a regular dose of MY10, known to block ethanol consumption and reward in wild type mice, also blocks the rewarding effects of ethanol in the more vulnerable individuals lacking PTN, the endogenous inhibitor of RPTPβ/ζ.

PTN drug alcohol 31054277 Overall, the data indicate that MY10 rescues Ptn / mice from their increased susceptibility to the conditioning effects of ethanol and may induce anxiolytic effects in individuals with reduced or absent PTN functions.

PTN addiction withdrawal 26222257 Second, to study if PTN may be involved in morphine physical dependence, naloxone precipitated withdrawal syndrome was induced in PTN / and WT morphine dependent mice. PTN drug opioid 26222257 Although the increase in the time spent in the morphine paired compartment after conditioning tended to be more pronounced in PTN / mice, statistical significance was not achieved. PTN drug opioid 26222257 The data suggest that PTN does not exert an important role in morphine reward. PTN addiction reward 26222257 The data suggest that PTN does not exert an important role in morphine reward. PTN addiction withdrawal 26222257 However, our results clearly indicate that PTN / mice develop a more severe withdrawal syndrome than WT mice, characterized as a significant increase in the time standing and in the total incidences of forepaw licking, forepaw tremors, wet dog shake and writhing.

PTN addiction addiction 25808239 Midkine and Pleiotrophin in the Treatment of Neurodegenerative Diseases and Drug Addiction. PTN addiction addiction 25808239 Pleiotrophin (PTN) and Midkine (MK) are neurotrophines with documented protective actions in experimental models of neurodegenerative diseases and beneficial effects on toxicity and addictive behaviours related to drug abuse. PTN addiction addiction 25808239 Pleiotrophin (PTN) and Midkine (MK) are neurotrophines with documented protective actions in experimental models of neurodegenerative diseases and beneficial effects on toxicity and addictive behaviours related to drug abuse.

PTN addiction reward 25808239 Concerning the latter, both PTN and MK prevent the neurotoxic effects of amphetamine on nigrostriatal pathways and endogenous PTN also limits amphetamine reward. PTN drug alcohol 25808239 Moreover, endogenous PTN overexpression in the prefontral cortex abolishes alcohol induced conditioned place preference. PTN drug opioid 25108770 Glial activation and midkine and pleiotrophin transcription in the ventral tegmental area are modulated by morphine administration. PTN drug opioid 25108770 Although a possible role for midkine and pleiotrophin cytokines in the field of synaptic plasticity has been proposed, it has not been assessed whether morphine administration regulates astrogliosis and midkine and pleiotrophin transcription. PTN drug opioid 25108770 Interestingly, single morphine injection and chronic morphine increased VTA midkine and pleiotrophin mRNA expression. PTN drug alcohol 25073406 Pleiotrophin differentially regulates the rewarding and sedative effects of ethanol. PTN drug alcohol 25073406 administration causes a significant up regulation of PTN mRNA and protein levels in the mouse prefrontal cortex, suggesting that endogenous PTN could modulate behavioural responses to ethanol. PTN drug alcohol 25073406 To test this hypothesis, we studied the behavioural effects of ethanol in PTN knockout (PTN( / )) mice and in mice with cortex and hippocampus specific transgenic PTN over expression (PTN Tg). PTN drug alcohol 25073406 Ethanol (1.0 and 2.0 g/kg) induced an enhanced conditioned place preference in PTN( / ) compared to wild type mice, suggesting that PTN prevents ethanol rewarding effects. PTN drug alcohol 25073406 Accordingly, the conditioning effects of ethanol were completely abolished in PTN Tg mice. PTN drug alcohol 25073406 However, the sedative effects of ethanol (3.6 g/kg) tested in a loss of righting reflex paradigm were significantly reduced in PTN Tg mice, suggesting that up regulation of PTN levels prevents the sedative effects of ethanol. PTN drug alcohol 25073406 These results indicate that PTN may be a novel genetic factor of importance in alcohol use disorders, and that potentiation of the PTN signalling pathway may be a promising therapeutic strategy in the treatment of these disorders.

PTN drug cocaine 24096156 We have previously demonstrated that PTN and MK modulate amphetamine induced neurotoxicity and that PTN prevents cocaine induced cytotoxicity in NG108 15 and PC12 cells. PTN drug cocaine 24096156 In an effort to dissect the different mechanisms of action triggered by PTN and MK to exert their protective roles against psychostimulant neurotoxicity, we have now used a proteomic approach to study protein phosphorylation, in which we combined phosphoprotein enrichment, by immobilized metal affinity chromatography (IMAC), with two dimensional gel electrophoresis and mass spectrometry, in order to identify the phosphoproteins regulated in the striatum of PTN knockout, MK knockout and wild type mice treated with a single dose of cocaine (15mg/kg, i.p.). PTN drug cocaine 24096156 Most of these proteins are related to neurodegeneration processes and oxidative stress and their variations specially affect the PTN knockout mice, suggesting a protective role of endogenous PTN against cocaine induced neural alterations. PTN drug cocaine 23891929 To test this hypothesis, cocaine (10 and 15mg/kg) induced conditioned place preference (CPP) was rendered in PTN knockout (PTN / ), MK knockout (MK / ) and wild type (WT+/+) mice, and then extinguished after repeated saline injections (distributed in 4 extinction sessions).

PTN drug cocaine 23891929 Particularly, 40% of MK / mice did not extinguish cocaine (15mg/kg) induced CPP compared to WT+/+ and PTN / mice (∼0 6%). PTN addiction reward 23891929 Particularly, 40% of MK / mice did not extinguish cocaine (15mg/kg) induced CPP compared to WT+/+ and PTN / mice (∼0 6%). PTN addiction reward 23891929 In contrast, a lower magnitude of CPP extinction correlates with increased phosphorylation of aconitase 2 in the prefrontal cortex of PTN / mice, suggesting that the correlation between the tyrosine phosphorylation levels of aconitase 2 and magnitude of CPP extinction depends on the genotype considered. PTN addiction addiction 23889475 Targeting midkine and pleiotrophin signalling pathways in addiction and neurodegenerative disorders: recent progress and perspectives. PTN addiction relapse 23889475 In this review, evidence demonstrating that MK and PTN limit the rewarding effects of drugs of abuse and, potentially, prevent drug relapse is compiled. PTN addiction addiction 23889475 Exogenous administration of MK and/or PTN into the CNS by means of non invasive methods is proposed as a novel therapeutic strategy for addictive and neurodegenerative diseases. PTN addiction addiction 23889475 Identification of new molecular targets downstream of the MK and PTN signalling pathways or pharmacological modulation of those already known may also provide a more traditional, but probably effective, therapeutic strategy for treating addictive and neurodegenerative disorders. PTN drug amphetamine 23178526 It was previously shown that mice with genetic deletion of pleiotrophin (PTN), a neurotrophic factor upregulated in different brain areas after administration of amphetamine, show a longer lasting amphetamine induced conditioned place preference (CPP) when compared to wild type mice.

PTN addiction reward 23178526 The data demonstrate that maintenance of amphetamine induced CPP depends on the endogenous expression of PTN. PTN drug amphetamine 23178526 The data tend to discard a correlation between activated astrocytes and maintenance of amphetamine conditioning effects and suggest PTN as a potential modulator of activation of astrocytes after amphetamine treatment. PTN drug amphetamine 21704677 Midkine regulates amphetamine induced astrocytosis in striatum but has no effects on amphetamine induced striatal dopaminergic denervation and addictive effects: functional differences between pleiotrophin and midkine. PTN addiction addiction 21704677 Midkine regulates amphetamine induced astrocytosis in striatum but has no effects on amphetamine induced striatal dopaminergic denervation and addictive effects: functional differences between pleiotrophin and midkine. PTN drug amphetamine 21704677 The data clearly suggest that endogenous MK limits amphetamine induced astrocytosis through Fyn , TrkA and ERK1/2 independent mechanisms and identify previously unexpected functional differences between MK and pleiotrophin, the only other member of the MK family of growth factors, in the modulation of effects of drugs of abuse. PTN addiction addiction 21375485 Recent evidences have shown pleiotrophin, a growth factor with important functions in remodeling and repair of injured neural tissue, as an important factor involved in the pathogenesis of both diseases by preventing neurodegeneration in Parkinson's disease, neurotoxicity induced by drug abuse and by its ability to modulate drugs addictive effects. PTN addiction addiction 21375485 This review discusses targeting growth factors such as glial derived neurotrophic factor (GDNF) and brain derived neurotrophic factor (BDNF) to treat Parkinson's disease and/or drug addiction and compiles recent evidences to propose the pleiotrophin/receptor protein tyrosine phosphatase β/ζ signaling pathway as a new therapeutic target to treat Parkinson's disease and to prevent drug of abuse induced neurotoxicity and addictive effects.

PTN drug amphetamine 20192945 To test this hypothesis, we have studied the effects of amphetamine administration in PTN genetically deficient (PTN / ) and wild type (WT, +/+) mice. PTN drug amphetamine 20192945 In conditioning studies, we found that amphetamine induces conditioned place preference in both PTN / and WT (+/+) mice. PTN drug amphetamine 20192945 When these mice were re evaluated after a 5 day period without amphetamine administration, we found that WT (+/+) mice did not exhibit amphetamine seeking behaviour, whereas, PTN / mice still showed a robust drug seeking behaviour. PTN addiction relapse 20192945 When these mice were re evaluated after a 5 day period without amphetamine administration, we found that WT (+/+) mice did not exhibit amphetamine seeking behaviour, whereas, PTN / mice still showed a robust drug seeking behaviour. PTN drug amphetamine 20192945 In immunohystochemistry studies, we found that amphetamine (10 mg/kg, four times, every 2 hours) causes a significant increase of glial fibrillary acidic protein positive cells in the striatum of amphetamine treated PTN / mice compared with WT mice 4 days after last administration of the drug, suggesting an enhanced amphetamine induced astrocytosis in the absence of endogenous PTN. PTN drug amphetamine 20192945 Interestingly, we found in concomitant in vitro studies that PTN (3 µM) limits amphetamine (1 mM) induced loss of viability of PC12 cell cultures, effect that could be related to the ability of PTN to induce the phosphorylation of Akt and ERK1/2. PTN drug amphetamine 20192945 To test this possibility, we used specific Akt and ERK1/2 inhibitors uncovering for the first time that PTN induced protective effects against amphetamine induced toxicity in PC12 cells are mediated by the ERK1/2 signalling pathway. PTN drug amphetamine 20192945 The data suggest an important role of PTN to limit amphetamine induced neurotoxic and rewarding effects. INSR drug opioid 30887859 The expression of Insr in the amygdala of control animals decreased over time while the opposite effect was seen in the rats that self administered morphine. INSR drug cocaine 30471157 Finally, intra VTA or intranasal insulin decreased locomotor responses to cocaine, an effect blocked by an intra VTA administered insulin receptor antagonist. INSR drug amphetamine 29698491 We found that rats fed a HF diet for only two weeks have reductions in striatal Akt activity, a marker of decreased striatal insulin receptor signaling and blunted striatal responsiveness to AMPH. INSR drug amphetamine 29698491 Because AMPH induces DA efflux and brain activation, in large part via DAT, these findings suggest that blunted central nervous system insulin receptor signaling through a HF diet can impair DA homeostasis, thereby disrupting cognitive and reward circuitry involved in the regulation of hedonic feeding.

INSR drug alcohol 29242853 Ethanol, NNK, and ethanol + NNK exposures significantly inhibited insulin receptor tyrosine phosphorylation, and IRS 1 and myelin associated glycoprotein expression. INSR drug alcohol 26586826 Here, we show that p70 S6 kinase (S6k), acting downstream of the insulin receptor (InR) and the small GTPase Arf6, is a key mediator of ethanol induced sedation in Drosophila. INSR drug alcohol 26586826 Here, we show that signaling from the insulin receptor in Drosophila neurons determines flies' sensitivity to ethanol induced sedation. INSR drug alcohol 26373814 Ethanol ± NNK, caused brain atrophy, inhibited insulin signaling through the insulin receptor and Akt, activated GSK 3β, increased protein carbonyl and 3 nitrotyrosine, and reduced acetylcholinesterase. INSR addiction intoxication 23363978 Insulin signaling in the hypothalamus, as assessed by insulin receptor and AKT phosphorylation, decreased after binge drinking.

INSR drug opioid 17143271 In this study, we used viral mediated gene transfer in rat to show that chronic morphine induced downregulation of the insulin receptor substrate 2 (IRS2) thymoma viral proto oncogene (Akt) signaling pathway in the VTA mediates the decrease in dopamine cell size seen after morphine exposure and that this downregulation diminishes morphine reward, as measured by conditioned place preference.

IFNA1 drug opioid 16406668 Previous studies have indicated that interferon alpha (IFN alpha) can bind to opioid receptors and exerts an antinociceptive effect in both peripheral and central nervous systems. IFNA1 drug opioid 16406668 The current study investigated the antinociceptive effect of IFN alpha unilaterally microinjected into the thalamic nucleus submedius (Sm) of rats on noxious thermal stimulus, and the roles of different subtypes of opioid receptors in mediating the Sm IFN alpha evoked antinociception. IFNA1 drug opioid 16406668 The results indicated that unilateral microinjection of IFN alpha (4, 8, 16 pmol) into the Sm dose dependently increased the hind paw withdrawal latency from the noxious heat stimulus, and this effect was reversed by pretreatment with non selective opioid receptor antagonist naloxone (200 pmol) and specific mu opioid receptor antagonist beta FNA (1 nmol) into the same sites, whereas delta opioid receptor antagonist ICI174,864 (1 nmol) and kappa opioid receptor antagonist nor BNI (1 nmol) failed to alter the effect of IFN alpha.

IFNA1 drug opioid 16406668 These results suggest that Sm is involved in IFN alpha evoked antinociception and mu but not delta and kappa opioid receptor mediates the Sm IFN alpha evoked antinociception. IFNA1 drug opioid 16251417 These in vitro observations support the concept that opioid abuse favors HCV persistence in hepatic cells by suppressing IFN alpha mediated intracellular innate immunity and contributes to the development of chronic HCV infection. IFNA1 drug amphetamine 16142050 Concerning the other monoaminergic systems, IFNalpha seems to have an amphetamine like effect at its first administration, followed by a decrease in dopaminergic tone with chronic administration.

Our aim was to obtain prospective data on adherence to as well as efficacy and mental side effects of treatment with IFN alpha in different psychiatric risk groups compared with controls. IFNA1 drug opioid 12540795 In a prospective trial, 81 patients with chronic hepatitis C (positive hepatitis C virus[HCV] RNA and elevated alanine aminotransferase[ALT] level) and psychiatric disorders (n = 16), methadone substitution (n = 21), former drug addiction (n = 21), or controls without a psychiatric history or drug addiction (n = 23) were treated with a combination of IFN alpha 2a 3 MU 3 times weekly and ribavirin (1,000 1,200 mg/d).

Interferon alpha (IFN alpha) is the only effective treatment for chronic hepatitis B and C. Over 2/3 of methadone substituted patients suffer from chronic hepatitis C but a history of psychiatric disorders or drug addiction is still seen as a contraindication for IFN alpha because of a possible increased risk of severe psychiatric side effects such as depression, suicide attempts or psychotic episodes.

IFNA1 drug opioid 9067644 The present study was undertaken to examine the immunomodulatory role of morphine on HIV protein induced lymphocyte proliferative responses, Sendai and Newcastle disease virus induced alpha IFN (IFN alpha) and IFN beta production by lymphocytes and fibroblast cells, respectively, and induction of apoptosis of normal lymphocytes in vitro. IFNA1 drug opioid 9067644 Furthermore, morphine significantly inhibited both IFN alpha and IFN beta production by normal lymphocytes and fibroblasts but induced apoptosis of normal lymphocytes. IFNA1 drug opioid 9067644 Inhibition of IFN alpha production by morphine could be reversed by the opiate receptor antagonist naloxone. HDAC1 drug amphetamine 30811820 For single dose, METH affected H4ac by increasing its acetylation at class I Hdac1 and class IIb Hdac10, decreasing it at class IIa Hdac4 and Hdac5. HDAC1 drug amphetamine 30811820 We found that METH increased H4ac in class IIa Hdac4 and Hdac5 and decreased H3/H4ac at class I Hdac1, Hdac2, and Hdac8. HDAC1 drug cocaine 30126647 Cocaine also increased testicular and germ cell acetylated histone 3 and 4 and decreased expression of histone deacetylases HDAC1/2. HDAC1 drug cocaine 30126647 Analysis of mRNA expression in isolated germ cells shows decreased levels of Hdac1/2/8, Dnmt3b and Tet1 and increased levels of Dnmt3a gene expression after cocaine treatment. HDAC1 drug amphetamine 30056065 In this study, we measured the effects of single dose injections of modafinil and METH on the protein levels of acetylated histone H3 (H3ac) and H4ac, deacetylases HDAC1 and HDAC2, and of the NMDA subunit GluN1 in the medial PFC (mPFC) of mice euthanized 1 h after drug administration. HDAC1 drug amphetamine 30056065 Acute modafinil and METH injections caused similar effects on total histone acetylation, increasing H3ac and decreasing H4ac, and they also increased HDAC1, HDAC2 and GluN1 protein levels in the mouse mPFC. HDAC1 drug amphetamine 29397902 In contrast, HDAC5 knockdown in the dorsal striatum decreased meth seeking on withdrawal day 30 but not on day 2; this manipulation also altered other HDACs (Hdac1 and Hdac4) and potential HDAC5 targets (Gnb4 and Suv39h1). HDAC1 addiction relapse 29397902 In contrast, HDAC5 knockdown in the dorsal striatum decreased meth seeking on withdrawal day 30 but not on day 2; this manipulation also altered other HDACs (Hdac1 and Hdac4) and potential HDAC5 targets (Gnb4 and Suv39h1). HDAC1 addiction withdrawal 29397902 In contrast, HDAC5 knockdown in the dorsal striatum decreased meth seeking on withdrawal day 30 but not on day 2; this manipulation also altered other HDACs (Hdac1 and Hdac4) and potential HDAC5 targets (Gnb4 and Suv39h1). HDAC1 drug alcohol 28798030 We found that class I histone deacetylases (HDACs) regulate ethanol induced changes in α1 gene and protein expression as pharmacologic inhibition or knockdown of HDAC1 3 prevents the effects of ethanol exposure. HDAC1 drug alcohol 28682229 Recent work in rodents has shown that systemic administration of pan HDAC class I and II inhibitors, TSA and N hydroxy N phenyl octanediamide [SuberoylAnilide Hydroxamic Acid] (SAHA), and of the more selective inhibitor (mainly HDAC1 and HDAC9) MS 275, decrease binge like alcohol drinking in mice. HDAC1 addiction intoxication 28682229 Recent work in rodents has shown that systemic administration of pan HDAC class I and II inhibitors, TSA and N hydroxy N phenyl octanediamide [SuberoylAnilide Hydroxamic Acid] (SAHA), and of the more selective inhibitor (mainly HDAC1 and HDAC9) MS 275, decrease binge like alcohol drinking in mice. HDAC1 addiction intoxication 28250112 Editorial: Binge drinking: lessons from ATF3 and HDAC1 collaboration. HDAC1 addiction intoxication 27260954 In binge drinking mice challenged with LPS, an up regulation of ATF3 and HDAC1 and a concomitant decrease in TNF α were observed. HDAC1 drug alcohol 27260954 Given that HDAC1 was concomitantly induced in acute ethanol exposed monocytes and macrophages, we used the HDACi TSA or silenced HDAC1 to explore the role of HDAC1 in acute ethanol treated macrophages. HDAC1 drug alcohol 27260954 Our results revealed that TSA treatment and HDAC1 knockdown prevented acute ethanol induced ATF3 expression and the inhibition of TNF α transcription. HDAC1 drug alcohol 27260954 These data indicated a dual role for HDAC1 in acute ethanol induced LPS tolerance. HDAC1 drug alcohol 27238566 nalmefene; (ii) the effects of nalmefene with increasing concentrations of alcohol; (iii) the efficacy of nalmefene on cocaine potentiated alcohol responding; and (iv) the gene expression profiles of histone deacetylases (Hdac1 11) in peripheral blood in vivo and in the prefrontal cortex, heart, liver and kidney post mortem.

HDAC1 drug alcohol 26365275 We primarily found that acute alcohol binging reduced gene expression (Hdac1 10) in the peripheral blood of alcohol naïve rats and that this effect was attenuated following repeated alcohol binges. HDAC1 drug nicotine 24789730 Nicotine inhibits the proliferation by upregulation of nitric oxide and increased HDAC1 in mouse neural stem cells. HDAC1 drug nicotine 24789730 Taken together, these data demonstrate that prolonged exposure of nicotine decreased proliferation of mNSCs by increased NO and inflammatory cytokine through increased HDAC1. HDAC1 drug alcohol 24551070 Similarly, ethanol treatment was found to induce the translocation of HDAC1/4 and HMGB1 proteins from nuclear to cytosolic fractions. HDAC1 drug alcohol 24551070 Furthermore, ethanol treatment reduced HDAC1/4 mRNA and increased acetylated HMGB1 release into the media. HDAC1 drug amphetamine 24239129 Moreover, METH caused interactions of REST corepressor 1 and methylated CpG binding protein 2 with histone deacetylase 2 and of REST with histone deacetylase 1. HDAC1 drug cocaine 23475113 Here we demonstrate that specific and prolonged blockade of HDAC1 in NAc of mice increased global levels of histone acetylation, but also induced repressive histone methylation and antagonized cocaine induced changes in behavior, an effect mediated in part through a chromatin mediated suppression of GABAA receptor subunit expression and inhibitory tone on NAc neurons. HDAC1 drug amphetamine 22470541 Our study investigated the effects of a non toxic METH injection (20 mg/kg) on gene expression, histone acetylation, and the expression of the histone acetyltransferase (HAT), ATF2, and of the histone deacetylases (HDACs), HDAC1 and HDAC2, in that structure. HDAC1 drug amphetamine 18632938 Accordingly, local knock out of HDAC1 in striatum abolishes amphetamine induced desensitization of the c fos gene. EIF2S1 addiction addiction 29539420 Reduced eukaryotic Initiation Factor 2 (eIF2)α phosphorylation (p eIF2α) enhances protein synthesis, memory formation, and addiction like behaviors. EIF2S1 drug opioid 28546432 Compared with the Heroin group, mRNA and protein expression of PERK, eIF2a, CHOP, IRE1 and JNK in the hippocampus and VTA were significantly downregulated in the Heroin+acupuncture group (p<0.05). EIF2S1 drug cocaine 27899881 New functional pathways were also identified for cocaine modulation (e.g., Rho GTPase signaling) and environmental enrichment (e.g., signaling of EIF2, mTOR, ephrin). EIF2S1 drug alcohol 27527870 Ethanol induced endoplasmic reticulum stress was demonstrated by a significant increase in ATF6, CHOP, and the phosphorylation of PERK and eiF 2alpha. EIF2S1 drug nicotine 26928076 When we investigated the influence of allelic variability of the Eif2s1 gene (encoding eIF2α) on reward related neuronal responses in human smokers, we found that a single nucleotide polymorphism in the Eif2s1 gene modulates mesolimbic neuronal reward responses in human smokers. EIF2S1 addiction reward 26928076 When we investigated the influence of allelic variability of the Eif2s1 gene (encoding eIF2α) on reward related neuronal responses in human smokers, we found that a single nucleotide polymorphism in the Eif2s1 gene modulates mesolimbic neuronal reward responses in human smokers. EIF2S1 drug alcohol 18334613 To date, alcohol induced alterations in eIF2 and eIF2B content and activity are best investigated. EIF2S1 addiction intoxication 18334613 The reduced eIF2B activity most likely is a consequence of twofold increased phosphorylation of the alpha subunit of eIF2 on Ser(51) following acute intoxication. EIF2S1 drug alcohol 18334613 The increase in eIF2alpha phosphorylation after chronic alcohol consumption is the same as that induced by acute ethanol intoxication, and protein synthesis is not further reduced by long term alcohol ingestion despite additional reduced expression of initiation factors and elongation factors. EIF2S1 addiction intoxication 18334613 The increase in eIF2alpha phosphorylation after chronic alcohol consumption is the same as that induced by acute ethanol intoxication, and protein synthesis is not further reduced by long term alcohol ingestion despite additional reduced expression of initiation factors and elongation factors. EIF2S1 drug alcohol 18334613 Indeed, pretreatment with Salubrinal, an inhibitor of eIF2alpha(P) phosphatase, before ethanol treatment does not further inhibit protein synthesis or increase eIF2alpha phosphorylation, suggesting that acute ethanol intoxication causes maximal eIF2alpha phosphorylation elevation and hepatic protein synthesis inhibition. EIF2S1 addiction intoxication 18334613 Indeed, pretreatment with Salubrinal, an inhibitor of eIF2alpha(P) phosphatase, before ethanol treatment does not further inhibit protein synthesis or increase eIF2alpha phosphorylation, suggesting that acute ethanol intoxication causes maximal eIF2alpha phosphorylation elevation and hepatic protein synthesis inhibition. EIF2S1 drug alcohol 18334613 In conclusion, sustained eIF2alpha phosphorylation is a hallmark of excessive alcohol intake leading to inhibition of protein synthesis. EIF2S1 drug alcohol 18334613 Enhanced phosphorylation of eIF2alpha represents a unique response of liver to alcohol intoxication, because the ethanol induced elevation of eIF2alpha(P) is not observed in skeletal muscle or heart. EIF2S1 addiction intoxication 18334613 Enhanced phosphorylation of eIF2alpha represents a unique response of liver to alcohol intoxication, because the ethanol induced elevation of eIF2alpha(P) is not observed in skeletal muscle or heart. EIF2S1 drug alcohol 11331201 In contrast, alcohol does not produce consistent alterations in the control of translation initiation by the eIF2 system. EIF2S1 drug alcohol 11052957 Acute alcohol intoxication did not significantly alter the myocardial content of eIF2 alpha or eIF2B epsilon, the extent of eIF2 alpha phosphorylation, or the activity of eIF2B. EIF2S1 addiction intoxication 11052957 Acute alcohol intoxication did not significantly alter the myocardial content of eIF2 alpha or eIF2B epsilon, the extent of eIF2 alpha phosphorylation, or the activity of eIF2B. EIF2S1 drug alcohol 11052957 These data suggest that the acute alcohol induced impairment in myocardial protein synthesis results, in part, from an inhibition in peptide chain initiation, which is associated with marked changes in eIF4E availability and p70S6 kinase phosphorylation but is independent of changes in the eIF2/2B system and IGFs. EIF2S1 drug alcohol 10776669 Hepatic eIF2B activity was decreased 24% in alcohol treated rats, and this was associated with a 95% increase in eIF2alpha phosphorylation. EIF2S1 drug alcohol 10776669 In contrast to liver, neither eIF2B activity nor the phosphorylation of eIF2alpha was affected in muscle of alcohol treated rats. EIF2S1 drug alcohol 3377809 The addition of ethanol to reticulocyte lysates led to increased phosphorylation of eIF 2 alpha and to a decrease in the rate of exchange of guanine nucleotides bound to eIF 2. EIF2S1 drug alcohol 3377809 Using purified components it was found that ethanol inhibited the ability of GEF to stimulate eIF 2 and that this inhibition showed a similar temperature dependence to the effect of ethanol on overall protein synthesis. EIF2S1 addiction dependence 3377809 Using purified components it was found that ethanol inhibited the ability of GEF to stimulate eIF 2 and that this inhibition showed a similar temperature dependence to the effect of ethanol on overall protein synthesis. EIF2S1 drug alcohol 3377809 Taken together, these results suggest that ethanol leads to inhibition of peptide chain initiation both through increased phosphorylation of eIF 2 alpha and by directly inhibiting the productive interaction of eIF 2 and GEF. CXCR4 drug alcohol 32150428 Attentional set shifting in HAP3, LAP3, and cHAP mice is unaffected by either genetic differences in alcohol preference or an alcohol drinking history. CXCR4 drug cocaine 31557508 Our results suggest that mesolimbic CCR5 receptors are dysregulated by cocaine exposure and, similar to CXCR4 and CCR2 receptors, influence behavioral effects related to the abuse liability of cocaine. CXCR4 drug opioid 31465771 However, the molecular mechanisms that underlie CXCR4, as well as opioid mediated regulation of dendritic spines are not completely defined. CXCR4 drug opioid 31465771 Here, we will consolidate studies that describe the region specific synaptodendritic damage in the cerebral cortex of patients and animal models of HAND, describe the pathways by which opioids may contribute to cortical synaptodendritic damage, and discuss the prospects of using the CXCR4 signaling pathway to identify new approaches to reverse dendritic spine deficits. CXCR4 drug opioid 31465771 Additionally, we will discuss novel research questions that have emerged from recent studies of CXCR4 and µ opioid actions in the cortex. CXCR4 drug alcohol 31009094 The MIF axis, for example, MIF and MIF receptors invariant polypeptide of major histocompatibility complex, class II antigen associated (CD74), CXCR2, CXCR4, and CXCR7, was enhanced in the livers of alcoholic hepatitis (AH) patients as compared to healthy controls. CXCR4 drug opioid 30249618 Dose response curves for morphine, maraviroc (a CCR5 antagonist), and AMD3100 (a CXCR4 antagonist) alone were established. CXCR4 addiction reward 29550625 The chemokine CXCL12 and its principal receptor target, CXCR4, are of particular interest because CXCR4 activation enhances mesolimbic dopamine output that facilitates psychostimulant reward, reinforcement, and locomotor activation. CXCR4 drug cocaine 29550625 Repeated cocaine enhances CXCL12 gene expression in the midbrain and produces conditioned place preference (CPP) that is inhibited by a CXCR4 antagonist.

CXCR4 addiction reward 29550625 We tested the hypothesis that an FDA approved CXCR4 antagonist (AMD3100) inhibits MDPV induced reward, locomotor activation and positive affective state in rats using a triad of behavioral assays (CPP, open field, and 50 kHz ultrasonic vocalizations [USVs]). CXCR4 drug cocaine 29550625 Our results identify the existence of chemokine/cathinone interactions and suggest the rewarding and stimulant effects of MDPV, similar to cocaine, require an active CXCL12/CXCR4 system. CXCR4 addiction intoxication 28481655 Compared to the low risk group, the binge group showed higher CCR5 expression on PMNs, decreases in the CD69 percentage and positive PMNs per microliter, and decreased CXCR4 expression on monocytes. CXCR4 drug cocaine 27575003 Chemokines and cocaine: CXCR4 receptor antagonist AMD3100 attenuates cocaine place preference and locomotor stimulation in rats. CXCR4 drug cocaine 27575003 To assess a role for the CXCL12/CXCR4 system in behavioral effects of cocaine, we tested the hypothesis that AMD 3100 (Plerixafor), a CXCR4 antagonist, would inhibit conditioned place preference (CPP) and locomotor activation produced by cocaine.

CXCR4 addiction intoxication 26151816 The Binge drinking group showed increased γGT together with increased expression of CD69 and reduced expression of TLR4, PD1, CCR2 and CXCR4 in peripheral CD8 cells. CXCR4 drug alcohol 26151816 PCA established 3 factors associated with alcohol consumption: "Early Activation" represented by CD69 and TLR4 expression in the CD8 population; "Effector Activation" by CD69 expression in CD8 CD127(+)CD137(+) and CD8 CD25(+) CD137(+); and Trafficking by CXCR4 expression on total CD8 and CD8 GB(+)CXCR4(+), and CCR2 expression on total CD8. CXCR4 drug alcohol 26151816 Alcohol consumption affects the immune phenotype of CD8 cells since binge drinking pattern was found to be associated with high CD69 and low TLR4, CXCR4 and CCR2 expression, which suggest recent activation, decreased sensitivity to LPS and lower migration capacity in response to chemokines SDF 1 and MCP 1.

CXCR4 drug opioid 24401274 Previous studies indicated that μ opioid agonists specifically elevate neuronal levels of the protein ferritin heavy chain (FHC), which negatively regulates CXCR4 signaling and affects the neuroprotective function of the CXCL12/CXCR4 axis. CXCR4 drug opioid 21465240 Levels of FHC as well as its effects on CXCR4 activation increase in cortical neurons exposed to mu opioid receptor agonists such as morphine, an effect likely specific to neurons.

BEAN1 addiction sensitization 8521183 Factors related to the development of sensitization to green coffee and castor bean allergens among coffee workers. BEAN1 addiction sensitization 8521183 Occupational allergic respiratory symptoms in coffee workers have been frequently reported, but the ultimate cause of sensitization is still debated, castor bean being considered besides green coffee beans. BEAN1 addiction sensitization 8521183 This study was carried out to assess the prevalence of allergic respiratory symptoms and of sensitization to both green coffee beans and castor bean in the whole workforce of a coffee manufacturing plant. BEAN1 addiction sensitization 8521183 The overall prevalence of skin sensitization was: 15% for green coffee beans, 22% for castor bean, 22% for common allergens.
