Web1.Introduction. Histone methylation and demethylation had vital impacts on regulating gene expression and genome integrity (Shi and Whetstine 2007; Liu et al. 2010).Histone methylation usually occurred at both lysine (K) and arginine (R) residues, including K4 (H3K4), K9 (H3K9), K27 (H3K27), K36 (H3K36) and K79 (H3K79) of histone H3 and … WebApr 19, 2013 · The gain in H3K27me3 peaks at the NM_001145306 promoter reduces the expression of this isoform.
