    Summary:

- -

-This April 2005 data set provides estimates of mRNA expression in normal kidneys of 32 strains of rats. 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 (MDC), Berlin Buch by Nobert 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 128 Affymetrix RAE230A array. This particular data set includes 120 arrays processed using a quantile normalized variant of the Affymetrix MAS5 protocol. The expression values of each array have been logged and adjusted to a mean of 8 and a stardard deviation of 2 (mean and variance stabilized). This data set complements the original MAS5 data set exploited by Hübner and colleagues 2005. -Download the particular transform in an Excel work book with both strain means and SEMs.

These data can also be viewed using the eQTL Explorer Java application -by John Mangion, Tim Aitman, and colleagues (Mueller et al. 2006). - - - - -

    About the cases used to generate this set of data:

-
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.

- -

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 geenration of continuous inbreeding (F60).

- -

Animals used in the transcriptome analyses of kidney and fat (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 (Hubner 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). -

- -

    About the tissue used to generate these data:

-
All tissues were collected at the age of 6 weeks. Kidneys and other organs were rapidly dissected and cleaned of fat, inserted into a vial, and immersed in liquid nitrogen for storage until RNA extraction. -
- - -
-The table below lists the arrays by strain and sample identifier. Each array was hybridized with mRNA from a single young male rat. -

    About the array platform:

- -

-Affymetrix 230A GeneChip: Expression data were generated using the Affymetrix 230A array. The chromosomal locations of probe sets were determined by BLAT analysis of concatenated probe sequences using the Rat Genome Sequencing Consortium assembly.

-
- -

    About Quality Control Procedures:

- -
-

RNA processing:RNA was extracted using Trizol reagent (Invitrogen) and purified using an RNeasy Mini kit from Qiagen. Double-stranded cDNA was generated without pooling. The Ambion MEGAscript T7 kit from Ambion was used to generate biotinylated cRNA for kidney. Fat samples were processed at this step using the Enzo Diagnostics Bioarray High Yield RNA Transcript labeling kit. See Hübner et al. 2005 for additional detail. One-hundred and twenty eight samples passed RNA quality control steps.

- -

Probe level QC: All 128 CEL files were collected into a single DataDesk 6.2 file. Probe data from pairs of arrays were plotted and compared. Eight arrays were considered potential outliers (despite having passed RNA quality control) and in the interest of minimizing technical variance, a decision was made to withhold them from the calculation of strain means used in WebQTL. The remaining 120 arrays were quantile normalized and reexamined in DataDesk to ensure reasonble colinearity of all array data sets.

- -

Probe set level QC: Probe set level QC involves counting the number of times that a single array data set from a single sample generates outliers at the level of the probe set consensus estimates of expression. With 120 arrays, any single array should generate a comparatively small fraction of the total number of outlier calls. This final step of array QC has NOT been implemented yet in this data set.

    About data processing:

- -
Probe (cell) level data from the CEL file: These CEL values produced by GCOS are 75% quantiles from a set of pixel measured in each cell. -
- - -
-

Probe set data: The original CEL values were log2 transformed and quantile normalized. We then took the antilog values of these quantile adjusted CEL values as input to the standard MAS5 algorithm. Probe set values listed in WebQTL pages are typically the averages of four biological replicates within strain.
