Data for all 12 microarray expression experiments are available for downloading in both tab-delimited text and Macintosh Excel 98 formats with file name: totaldataset. These include the averages (AVE) and standard errors (SE)of four spotted cDNA microarray hybridizations for each experiment, analyzed as indicated in Materials and Methods. These data include mutant versus wild type and mutant versus mutant hybridizations as indicated in the header. The full list of genes derepressed by isw2 mutation in sin3 or rpd3 mutant backgrounds are also available as text or in Macintosh Excel 98 format with file name: synth_isw2. This list is the 315 genes that are at least 1.7-fold derepressed in isw2 sin3 and/or isw2 rpd3 mutant backgrounds versus sin3 or rpd3 mutants, respectively. (A portion of these genes can be found in Table 3.)
