Figure 2From: Cell type-specific anti-cancer properties of valproic acid: independent effects on HDAC activity and Erk1/2 phosphorylation Effects of VPA on cell growth. Dose-response curves showing the effects of VPA on cell growth. Cells were exposed to VPA (0-3 mM, 48 h) before growth was determined using crystal violet staining. Results were normalized to the corresponding cells untreated with VPA from four independent experiments.Back to article page
