The effects of HDACi. Representative western blots of ΔNp63 (72 kDa) and β-actin (42 kDa) as loading control in HaCaT, FaDu or SCC-25 cells 24 h after treatment with A sodium butyrate, B valproic acid, C SAHA (vorinostat) or D trichostatin A. Relative ΔNp63 densitometry measurements normalized to β-actin are indicated, with 0 used as control. See Additional file 9 for nicotinamide treated cells
