(A) Western blotting verification of acetyl-H4 and H4 expression levels in control, HDAC1-OE (H1 OE), and TSA-treated H1-OE cells. GAPDH was used as a loading control. (B, C) QRT-PCR analysis of the three germ layer genes at day 6 of EB differentiation in control, H1-OE, and TSA-treated H1-OE cells. (D) Western blotting verification of acetyl-H4 and H4 expression levels in control, HDAC3-OE (H1 OE), and TSA-treated H3-OE cells. GAPDH was used as a loading control. (E, F) QRT-PCR analysis of the three germ layer genes at day 6 of EB differentiation in control, H3-OE, and TSA-treated H3-OE cells. Data are expressed as means ± SD. Statistical significance was assessed by two-tailed Student's t test. ***, P<0.001; **, P<0.01; *, P<0.05.
