Through Cistrome‐GO analysis under enhancer mode, (within the distance 15 × 10 kb),[65] top genes mapped to these regions (genes overlapping [‐75 kb, 75 kb] as corresponding top genes) were found to include estrogen‐regulated BRCA genes (eg., TFF1), cancer/testis antigens (eg., BAGE), epithelial growth factor receptor (eg., EGFR), and genes involved in cancer mutagenic process (eg., APOBEC3B)[66, 67, 68, 69] (Figure 5A; Table S4, Supporting Information). This evidence concerns the gene APOBEC3B and cancer.
