Data were generated at UTHSC and the University of Memphis with support from grants from the NIAAA Integrative Neuroscience Initiative on Alcoholism (<a href="http://www.iniastress.org" target="_blank" class="fs14">INIA</a>). Samples were hybridized in small pools (<I>n</I> = 3) to a total of 105 Affymetrix M430A and B array pairs. This particular data set was processed using the <a href="http://stat-www.berkeley.edu/users/bolstad/RMAExpress/RMAExpress.html" target="_blank" class="fs14">RMA</a> protocol. To simplify comparisons among transforms, RMA values of each array were adjusted to an average of 8 units and a standard deviation of 2 units. -</P> -</Blockquote> - - -<P class="subtitle"> About the cases used to generate this set of data:</P> - -<Blockquote> -We have used a set of 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 for D). Physical maps in WebQTL incorporate approximately 1.75 million B vs D SNPs from <a href="http://www.celeradiscoverysystem.com/index.cfm" target="_blank" class="fs14">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. These strains are available from The Jackson Laboratory. BXD43 through BXD99 were bred by Lu Lu, Jeremy Peirce, Lee M. Silver, and Robert W. Williams in the late 1990s and early 2000s using advanced intercross progeny (Peirce et al. <a href="http://www.biomedcentral.com/1471-2156/5/7" target="_blank" class="fs14">2004</a>). Many of the 50 new BXD strains are available from <A HREF="mailto:lulu@nb.utmem.EDU" target="_blank" class="fs14">Lu Lu</A> and colleagues</P> - -<P> All stock was obtained originally from The Jackson Laboratory between 1999 and 2003. Most BXD animals were born and housed at the University of Tennessee Health Science Center. Some cases were bred at the University of Memphis (Douglas Matthews) or the University of Alabama (John Mountz and Hui-Chen Hsu). -</P></Blockquote> - - -<P class="subtitle"> About the tissue used to generate this set of data:</P> - -<Blockquote>The <a href="http://www.iniastress.org" target="_blank" class="fs14">INIA</a> M430 brain Database (April05) consists of 105 Affymetrix 430A and 430B microarray pairs. Each pair was hybridized in sequence (A array first, B array second) with a pool of brain tissue (forebrain minus olfactory bulb, plus the entire midbrain) taken from three adult animals of closely matched age and the same sex. RNA was extracted at UTHSC by Lu Lu, Zhiping Jia, and Hongtao Zhai. All samples were subsequently processed in the INIA Bioanalytical Core at the W. Harry Feinstone Center of Excellence by Thomas R. Sutter, Shirlean Goodwin, and colleagues at the University of Memphis. - -<P><B>Replication and Sample Balance:</B> Our goal is to obtain data for independent biological sample pools from at least one of sample from each sex for all BXD strains. We have not yet achieved this goal. Ten of 45 strains are still represented by single sex samples: BXD2 (F), BXD8 (F), BXD15 (F), BXD18 (F), BXD25 (F), BXD29 (F), BXD33 (M), BXD45 (F), BXD77 (M), and BXD90 (M). Eleven strains are represented by three independent samples with the following breakdown by sex: C57BL/6J (1F 2M), DBA/2J (2F 2M), B6D2F1 (2F 2M) + D2B6F1 (1F 1M), BXD6 (2F 1M), BXD13 (2F 1M), BXD14 (1F 2M), BXD28 (2F 1M), BXD34 (1F 2M), BXD36 (1F 2M), BXD38 (1F 2M), BXD42 (1F 2M). - -<P><B>Batch Structure:</B> Before running the first batch of 30 pairs of array (dated Jan04), we ran four test samples (Nov03). The main batch of 30 includes the four test samples (four technical replicates). The Nov03 data was combined with the Jan04 data and was treated as a single batch that consists of one male and one female pool from C57BL/6J, DBA/2J, the B6D2F1 hybrid, 11 female BXD samples, and 11 male BXD samples. The second large batch was run February 2005 (Feb05) and consists of 71 pairs of arrays. Batch effects were corrected at the individual probe level as described below. - - -<P>The table below summarizes information on strain, sex, age, sample name, batch result date, and source of mice. -

The consequence of this simple set of transformations is to produce a set of Z scores that have a mean of 8, a variance of 4, and a standard deviation of 2. The advantage of this modified Z score is that a two-fold difference in expression level corresponds approximately to a 1 unit difference. - -<LI>Step 6: We eliminated much of the systematic technical variance introduced by the two batches (n = 34 and n = 71 array pairs) at the probe level. To do this we calculated the ratio of each batch mean to the mean of both batches and used this as a single multiplicative probe-specific batch correction factor. The consequence of this simple correction is that the mean probe signal value for each batch is the same. - -<LI>Step 7a: The 430A and 430B arrays include a set of 100 shared probe sets (a total of 2200 probes) that have identical sequences. These probes and probe sets provide a way to calibrate expression of the 430A and 430B arrays to a common scale. To bring the two arrays into alignment, we regressed Z scores of the common set of probes to obtain a linear regression correction to rescale the 430B arrays to the 430A array. In our case this involved multiplying all 430B Z scores by the slope of the regression and adding or subtracting a small offset. The result of this step is that the mean of the 430A expression is fixed at a value of 8, whereas that of the 430B chip is typically reduced to 7. The average of the merged 430A and 430B array data set is approximately 7.5. - -<LI>Step 7b: We recentered the merged 430A and 430B data sets to a mean of 8 and a standard deviation of 2. This involved reapplying Steps 3 through 5. - -<LI>Step 8: Finally, we computed the arithmetic mean of the values for the set of microarrays for each strain. Technical replicates were averaged before computing the mean for independent biological samples. Note, that we have not (yet) corrected for variance introduced by differences in sex, age, source of animals, or any interaction terms. We have not corrected for background beyond the background correction implemented by Affymetrix in generating the CEL file. We eventually hope to add statistical controls and adjustments for some of these variables. - -</UL> - - -<B>Probe set data: </B>The expression data were processed by Yanhua Qu (UTHSC). The original CEL files were read into the R environment (Ihaka and Gentleman 1996). Data were processed using the Robust Multichip Average (<a target="_blank" href="http://www.bioconductor.org" class="fs14">RMA</a>) method (Irrizary et al. 2003). Values were log2 transformed. Probe set values listed in WebQTL are the averages of biological replicates within strain. A few technical replicates were averaged and treated as single samples. A 1-unit difference represents roughly a two-fold difference in expression level. Expression levels below 5 are usually close to background noise levels. - -<P>This data set include further normalization to produce final estimates of expression that can be compared directly to the other transforms (average of 8 units and stabilized standard deviation of 2 units within each array). Please seee Bolstad and colleagues (<A href="http://www.stat.berkeley.edu/users/bolstad/normalize/normalize.html" class="fs14">2003</A>) for a helpful comparison of RMA and two other common methods of processing Affymetrix array data sets. -</Blockquote> - - -<P class="subtitle"> About the chromosome and megabase position values:</P> - -<Blockquote>The chromosomal locations of probe sets included on the microarrays were determined by BLAT analysis using the Mouse Genome Sequencing Consortium May 2004 Assembly (see <a href="http://genome.ucsc.edu/cgi-bin/hgBlat?command=start&org=mouse" class="fs14">http://genome.ucsc.edu/cgi-bin/hgBlat?command=start&org=mouse</a>).
