The rate of literature cocitation with the term “leukemia” within different gene groups. The proportion of genes cocited with the term leukemia is the highest among hub TFs in the regulatory networks (21 genes), followed by that of nonhub TFs in our regulatory networks (181 genes), and then those of other human TFs that have binding motifs annotated in the TRANSFAC and JASPAR databases (117 genes), differentially expressed genes (418 genes), and classification markers (62 genes), all of which are significantly higher than the proportion within all genes available on both Affymetrix HG-U133A and HG-U95 microarrays (8178 genes).
