The set includes the hypertensive SHR strain, the normotensive BN strain, and 30 HXB/BXH recombinant inbred strains. Each strain was sampled in quadruplicate (6-week-old males). Animals and tissues were generated by Michal Pravenec and colleagues at the Czech Academy of Sciences (CAS). RNA samples were processed at the Max-Delbrück-Center for Molecular Medicine (MDC), Berlin Buch by <A HREF="http://www.mdc-berlin.de/englisch/research/e_index.htm" target="_blank" class="fs14">Nobert Hübner</A> and colleagues. Transcriptome mapping was carried out by Norbert Hubner, Timothy Aitman and colleagues at the MDC and the MRC Clinical Sciences Centre, Imperial College, London (ICL). Samples were hybridized individually to a total of 128 Affymetrix RAE230A array. This particular data set includes 120 arrays processed using the RMA protocol. The expression values are original RMA output values without further normalization. This data set complements the MAS5 data set exploited by Hubner and colleagues <A HREF="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=15711544" target="_blank" class="fs14">2005</A>. +<A HREF="./array_data/Rat_230A_Kidney/Transform/KI_2A_0405_R.xls" class="fs14">Download</A> the particular transform in an Excel work book with both strain means and SEMs. +</P> + +<P>These data can also be viewed using the <A HREF="http://web.bioinformatics.ic.ac.uk/eqtlexplorer/" target="_blank" class="fs14">eQTL Explorer</A> Java application +by John Mangion, Tim Aitman, and colleagues (Mueller et al. <A HREF="http://bioinformatics.oxfordjournals.org/cgi/reprint/btk007v1.pdf +" target="_blank" class="fs14">2006</A>). + + +</Blockquote> + +<P class="subtitle"> About the cases used to generate this set of data:</P> +<Blockquote>Data were generated using the HXB/BXH recombinant inbred strains of rats generated over the past 20 years in Prague. The parental strains from which all HXB lines are derived are SHR (SHR/OlaIpcv or HSR = H) and Brown Norway (BN.Lx/Cub= B). These strains have been used extensively to study cardiovascular system physiology and genetics.</P> + +<P>The HXB strains were bred by Michal Pravenec at the Institute of Physiology, Czech Academy of Sciences. The BXH strains were bred by Vladimir Kren (see Pravenec et al. 1989, 2004) at a similar animal facility at the Institute of Biology and Medical Genetics, 1st Medical Faculty, Charles University. These strains are at approximately the 60th generation of continuous inbreeding (F60).</P> + +<P>Animals used in the transcriptome analyses of kidney and fat (Hubner and colleagues, <A HREF="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=15711544" target="_blank" class="fs14">2005</A>) were weaned at 4 weeks. Those born at the Charles University were transferred to the Institute of Physiology. Animals were reared on a commercial rat chow (ST-1 from VELAZ, Czech Republic). Four males were house per cage. Cages were made of polystyrene and have a floor size of 22 x 38 cm and height of 23 cm. The bedding was changed twice a week. Light cycle was 12:12 on-off. Vivarium rooms were maintained at 23 degrees C. Rats were sexually naive. All males used in the initial transcriptome studies (Hübner et al., 2005) were born between May and August 2002. They were sacrificed unfastged by rapid cervical dislocation between 9 and 10 AM, following an approved animal protocol (Ethics Committee of the Institute of Physiology, Czech Academy of Sciences, Prague; Animal Protection Law of the Czech Republic (311/1997). +</Blockquote> + +<P class="subtitle"> About the tissue used to generate these data:</P> +<Blockquote>All tissues were collected at the age of 6 weeks.
