Enriched H3K4me3 peaks (enrichment fold difference with respective control indicated in parenthesis) occupied promoters of two functionally related genes, heat shock protein 1a1 (Hspa1a) and Hspa1b in diabetes-exposed (6.54 fold, FDR = 0.02) and diet-exposed (5.62 fold, FDR < 0.001) groups, respectively (Table 2, Supplementary Table S2). This evidence concerns the gene HSPA1B and diabetes mellitus.
