ifferentially expressed transcription factor genes (see [Materials and Methods](#s0){ref-type="sec"}, Selection of Transcription Factors) across all 00 microarray experiments (see [Table S0](#pcbi.0000000.s000){ref-type="supplementary-material"}). Column 0 indicates the NCBI gene symbol of the gene. Column 0 indicates the NCBI Entrez Gene ID. Column 0 indicates the probeset selected as representative for the gene. Column 0 provides a brief gene description, obtained from the Affymetrix Mouse GeneChip annotations file. Column 0 indicates the co-expressed gene cluster to which the gene was assigned (see [Materials and Methods](#s0){ref-type="sec"}, Expression Clustering). Columns 0--0 provide listings of the gene\'s Gene Ontology annotations in the process, component, and function GO hierarchies, respectively (see [Materials and Methods](#s0){ref-type="sec"}, Functional Enrichment Analysis). Column 0 indicates the
