Effects of VA on the key proteins of apoptosis in MCF-7 cells. Immunoblots of Bcl-2, Bax, Bad and pBad protein levels in MCF-7 cells untreated or treated with valproic acid for 24 and 48 h. GAPDH was used as a protein loading control. Histograms represent the mean ± SD of three separate experiments in which band intensities were evaluated as optical density (OD) and expressed as fold change relative to control. **p < 0.005 vs Control (C)
