Cox2 levels in VA breast cancer treated-cells. Immunoblots of Cox2 levels in MCF-7 (A) and MDA-MB-231 (B) 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 < 0.05 and **p < 0.005 vs Control (C)
