The growth inhibition of VPA treatment on various PCa cells. LNCaP C-33/C-81, LNCaP C4-2/C4-2B, MDA PCa2B AS/AI, NE 1-3/1-8, PC-3 and DU 145 PCa cell lines were plated in 6-wells plates and then treated with 1 mM VPA or solvent for 48 h. Cells were then maintained in a steroid-reduced medium for 3 days. Total cell number was counted. The ratio of cell growth was calculated by normalizing the cell number to that of control cells (n = 3×2).
