Effect of SFN on the protein expressions of DNMTs (A), HDACs (B), and acetylated histone 3 (Ac-H3) (C) in TRAMP C1 cells. Cell lysates were prepared after SFN with the indicated doses for 5 days, followed by Western blotting to analyze protein expressions of DNMTs, HDACs, and Ac-H3 using specific antibodies. β-Actin was used as an equal loading control.
