The July 2007 data freeze provides estimates of mRNA expression in the <A HREf="http://www.nervenet.org/NetPapers/Rosen/Striatum2001/StriatumMain.html" target="_blank" class ="normalsize">striatum</A> (caudate nucleus of the forebrain) of 50 lines of mice, including the C57BL/6J and DBA/2J parental strains, their F1 hybrid (B6D2F1), 30 BXD recombinant inbred strains, and 17 more common inbred strains of mice. Data were generated using the new Affymetrix <A HREF="http://www.affymetrix.com/products/arrays/specific/mouse_exon.affx" target="_blank" class ="normalsize">Mouse Exon 1.0 ST</A> short oligomer microarrays by Weikuan Gu, Yan Jiao, David Kulp, and Lu Lu, Glenn D. Rosen, and Robert W. Williams with the support of a grant from the High Q Foundation. This is the first "all exons" array that we have entered into GeneNetwork and the data are still experimental. Approximately 300 brain samples (males and females) from 50 strains were used in this experiment. This data set includes 97 arrays that passed very stringent quality control procedures. Data were processed using the <A HREF="http://bmbolstad.com/misc/ComputeRMAFAQ/ComputeRMAFAQ.html" target="_blank" class ="normalsize">RMA method</A> of Irizarry, Bolstad, Speed, and colleagues. To simplify comparison among transforms, RMA values of each array were adjusted to an average expression of 8 units and a standard deviation of 2 units. </blockquote> <P class="subtitle"> About the strains and cases used to generate this set of data:</P> <Blockquote> <P>We have used a set of 30 BXD recombinant inbred strains generated by crossing C57BL/6J (B6 or B) with DBA/2J (D2 or D). The BXDs are particularly useful for systems genetics because both parental strains have been sequenced (8x coverage of B6 and 1.5x coverage of D). Physical maps in WebQTL maps incorporate approximately 1.75 million B vs D SNPs from <a href="http://www.celeradiscoverysystem.com/index.cfm" target="_blank" class ="normalsize">Celera</a>. BXD2 through BXD32 were bred by Benjamin A. Taylor starting in the late 1970s. BXD33 through 42 were bred by Taylor in the 1990s. All of these strains are available from The Jackson Laboratory.</P> </P> </Blockquote> <blockquote> <P><B>Mouse Diversity Panel (MDP)</B>. We have also profiled a MDP consisting at total of 19 inbred strains (this number includes the C57BL/6J and DBA/2J strains) and one F1 hybrid (B6D2F1 only; not D2B6F1 yet).

However, the previous study included fewer samples (47) and fewer strains (31 total). Animals were obtained from The Jackson Laboratory and housed for several weeks at BIDMC until they reached ~2 months of age (range from 55 to 62 days). Mice were killed by cervical dislocation and brains were removed and placed in RNAlater for 20 to 25 minutes prior to dissection. Cerebella and olfactory bulbs were removed; brains were hemisected, and both striata were dissected using a medial approach by GD Rosen that typically yields 5 to 7 mg of tissue per side. <P>All striatal dissections were performed by one person (GD Rosen) using a midsagittal approach that minimizes the likelihood of contamination across tissues. This dissection recovers most, but not all, of neostraitum. We have histologically examined dissected tissue and have found that no evidence of inclusion of cortical or thalamic tissue at the margins. We have further confirmed the dissections by comparative assays for acetylcholinesterase (AChE) protein levels using Western blots. The concentration of AChE in the striatum is far higher than that in cortex or cerebellum. A pool of dissected tissue from 3 or 4 adults (approximately 25 to 30 mg of tissue) of the same strain, sex, and age was collected in one session and used to generate cRNA samples. <P>Roughly 90 to 95% of all cells in the striatum are medium spiny neurons (Gerfen, <A HREF="http://www.nervenet.org/netpapers/gerfen/striatum92.html" target="_blank" class="fs14">1992</A>, for a review of the structure and function of the neostriatum). </Blockquote> <Blockquote> <P><B>RNA Extraction:</B> RNA was extracted by Rosen and colleagues between June 2, 2004 and March 8, 2006. In brief, we used the RNA STAT-60 <A HREF="http://www.tel-test.com/prod02.htm" target="_empty" class="fs14">protocol</A> (TEL-TEST "B" Bulletin No. 1), steps 5.1A (homogenization of tissue), 5.2 (RNA extraction), 5.3 (RNA precipitation), and 5.4 (RNA wash). In Step 5.4 we stopped after adding 75% ethanol (1 ml per 1 ml RNA STAT-60) and stored the mix at -80 deg C until further use. Before RNA labeling we thawed samples and proceeded with the remainder of Step 5.4; pelleting, drying, and redissovling the pellet in RNAase-free water. <!--FULL TEL-TEST text on RNA-60 Stat protocol <P>5. PROTOCOL: RNA/mRNA isolation by the RNA STAT-60 method includes the following steps: <br>1. Homogenization RNA STAT-60TM (1 ml per 50-100 mg tissue, or 5-10 x 10-6 cells) <br>2. RNA Extraction 1 vol. of homogenate +0.2 vol. of chloroform <br>3. RNA Precipitation 0.5 vol. of isopropanol <br>4. RNA Wash 75% ethanol <P>Unless stated otherwise the procedure is carried out at room temperature. <P>5.1 HOMOGENIZATION <P>A. TISSUES: Homogenize tissues samples in the RNA STAT-60(1 ml/50-100mg tissue)</B> in a glass-Teflon or Polytron homogenizer. Sample volume should not exceed 10% of the volume of the RNA STAT-60 used for homogenization. <P>B. CELLS: Cells grown in mono layer are lysed directly in a culture dish by adding the RNA STAT-60TM (1 ml/3.5 cm petri dish) and passing the cell lysate several times through a pipette. Cells grown in suspension are sediment then lysed in the RNA STAT-60TM (1 ml per 5-10 x 106 cells) by repetitive pipetting. Washing calls before addition of the RNA STAT-60TM should be avoided as this increases the possibility of mRNA degradation. <br> <P>5.2 RNA EXTRACTION: Following homogenization, store the homogenate for 5 min at room temp to permit the complete dissociation of nucleoprotein complexes. Next, add 0.2 ml of chloroform per 1 ml of the RNA STAT-60, cover the sample tightly, shake vigorously for 15 seconds and let it stay at room temperature for 2-3minutes. Centrifuge the homogenate at 12,000g (max) for 15 minutes at 4 deg C. Following centrifugation, the homogenate separates into two phases: a lower red phenol chloroform phase and the colorless upper aqueous phase. RNA remains exclusively in the aqueous phase whereas DNA and proteins are in the interferes and organic phase. The volume of the aqueous phase is about 60% of the volume of RNA STAT-60 used for homogenization. <P>5.3 RNA PRECIPITATION: Transfer the aqueous phase to a fresh tube and mix with isopropanol. Add 0.5 ml of isopropanol per 1 ml of the RNA STAT-60 used for homogenization. Store samples at room temp for 5-10 minutes and centrifuge at 12,000g (max.) for 10 min at 4 deg C</B>. RNA precipitate (often visible before centrifugation) forms a white pellet at the bottom of the tube. <P>5.4 RNA WASH: Remove supernatant and wash the RNA pellet once with 75% ethanol by vortexing and subsequent centrifugation at 7,500g (max.) for 5 min at 4<SUP>o</SUP>C. Add at least <B>1 ml of 75% ethanol per 1 ml of the RNA STAT-60 used for the initial homogenization. <P>At the end of the procedure, dry the RNA pellet briefly by air-drying or in a vacuum (5-10 min.). It is important not to let the RNA pellet dry completly as it will greatly decrease its solubility. Do not use the Speed-Vac for drying. Dissolve the RNA pellet in water or in 1 mm EDTA, pH 7, or 0.5% SDS solution. Vortex or pass the pellet a few times through a pipette tip. An incubation for <B>10-15 minutes at 55-60<SUP>o</SUP>C</B> may be required to dissolve RNA samples. Diethylpyrocarbonate (DEPC) treated RNase-free solutions<SUP>1</SUP> should be used for solubilization of RNA.

We have succeeded for 44 of 50 strains. Several strains are represented by only a single sex or a single sample pool. This sex imbalance can lead to bias with respect to transcripts that have genuine sex differences. One way to handle this issue is to study the correlation between a proxy variable for this bias, as represented by the <I>Xist</I> probe set 5153684, and a data set of interest. </DIR> </DIR> <P> <IMG src="/images/upload/XistStriatumExonJul07.gif" valign="top"> <P><SMALL><B>Legend: </B>Sex balance in this data set is illustrated using the sex-specific <I>Xist</I> gene and one of its probe sets (Affy Exon ST probe set: 5153684). Most samples include one male sample pool with very low Xist expression (6 or 7) and one female sample pool with high Xist expression (10 to 12). As a result 43 of the 50 strains have both intermediate values and high variance. The B6D2F1 sample has no error bar due to an early data entry error.

The same simple steps described above were also applied to these values. Every microarray data set therefore has a mean expression of 8 with a standard deviation of 2. A 1 unit difference represents roughly a two-fold difference in expression level. Expression levels below 5 are usually close to background noise levels. </Blockquote> <Blockquote><B>Data quality control: </B>A total of 97 samples passed RNA quality control. <P>Part1: Testing if replicates come from the same strain <OL> <LI> RMA normalized values were used in this analysis <LI>Pair-wise correlations were calculated between all the arrays using the probesets with high variance and high median <LI>Probability density of correlations between non-replicate pairs and replicate-pairs were calculated <LI>Threshold of 0.85 using Maximum likelihood estimate <LI>In total 5 set of replicates might not have come from the same strains.
