The parental strains from which all HXB lines are derived are SHR (SHR/OlaIpcv, abbreviated SHR or HSR = H) and Brown Norway (BN-Lx/Cub= B). These strains have been used extensively to study cardiovascular system physiology and genetics.

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 6oth generation of continuous inbreeding (F60).
+ +Animals used in the transcriptome analyses of multiple tissues (Hübner and colleagues, 2005) were weaned at 4 weeks. Those born at the Charles University were transferred to the Institute of Physiology. Animals were reared on a commerical 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 deg. 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 Protectiion Law of the Czech Republic (311/1997).

This December 2008 data set provides estimates of mRNA expression in normal adrenal glands of 31 strains of rats including the hypertensive SHR strain (aka HSR), the normotensive BN strain, and 29 HXB/BXH recombinant inbred strains. Most strains were 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 (MDC), Berlin Buch by Norbert Hübner and colleagues. Transcriptome mapping was carried out by Timothy Aitman and colleagues at the Imperial College, London (ICL). Samples were hybridized individually to a total of approximately 124 Affymetrix RAE230A array processed using the RMA protocol. The expression values of each array have been logged and adjusted to a mean of 8 and a standard deviation of 2 (mean and variance stabilized). This data set complements the kidney and fat data set exploited by Hübner and colleagues 2005.
