Enriched transcription factor genes in CGI probe loci within each of the five transgenerational methylation maintenance categories.

CGI microarray probe sequences were assessed for 459 human TFBS motifs from TRANSFAC using TFBS motif searching algorithm MATCH, with a significant individual TFBS enrichment threshold determined by Fisher's exact test and a p-value justified by Bonferroni correction of 0.05/459/5 = 2.2×10−5 (i.e., p = 0.05/459 TFBS motifs/five methylation maintenance categories) when background sets were selected as #1 in Table 2.
