For example, BACH1 attracts Nanog homeobox (NANOG) and mixed‐lineage leukemia/SET domain‐containing (MLL/SET1) complexes to chromatin, preserving H3K4me3 and enhancer‐promoter activity on genes related to pluripotency in mouse embryonic stem cells (mESCs),[18] and recruits coactivator‐associated arginine methyltransferase 1 (CARM1) to activate the genes’ transcription during in vitro VSMC differentiation from hESCs.[19] Consequently, the epigenetic regulatory roles of BACH1 might be tissue‐, cell‐type‐, or disease‐specific. This evidence concerns the gene BACH1 and leukemia.
