Fig. 8From: Valproic acid inhibits cell growth in both MCF-7 and MDA-MB231 cells by triggering different responses in a cell type-specific mannerExpression of cytochrome C and PARP in breast cancer treated-cells. Immunoblots of cytochrome C and cleaved-PARP protein levels in MCF-7 (A) and MDA-MB-231 (B) cells untreated or treated with VA for 24 and 48 h. GAPDH and actin were used as a protein loading control. Histograms represent the mean ± SD of three separate experiments in which bandi ntensities were evaluated as optical density (OD) and expressed as fold change relative to control *p<0.05 and **p<0.005 vs Control (C)Back to article page
