The KAT6A expressions were decreased in aging BMSCs. a The acetylation levels of lysine in YBMSCs and OBMSCs were explored by western blot, and quantitative analysis was performed by ImageJ (n = 6). b The expressions of Histone H3, acetyl-Histone H3, Histone H4, and acetyl-Histone H4 were explored by western blot, and quantitative analysis was performed by ImageJ (n = 6). c The expressions of KAT6A mRNA in YBMSCs and OBMSCs were explored by qRT-PCR (n = 6). d The expressions of KAT6A protein in YBMSCs and OBMSCs were explored by western blot, and quantitative analysis was performed by ImageJ (n = 6). e The acetylation levels of H3K9 in YBMSCs and OBMSCs were explored by western blot, and quantitative analysis was performed by ImageJ (n = 6). f The acetylation levels of H3K14 in YBMSCs and OBMSCs were explored by western blot, and quantitative analysis was performed by ImageJ (n = 6)
