Effects of silymarin on apoptosis-related protein in AGS human gastric cancer cells. (A) AGS cells were treated with silymarin (0, 40 and 80 µg/ml) for 24 h and cells were harvested to assess protein levels of Bax, Bcl-2, and PARP by western blotting. The blots were also probed with anti-β-actin antibody to confirm equal sample loading. (B) Each bar represents the mean ± SD calculated from three independent experiments. *P<0.05, statistically significant compared with untreated controls (Dunnett's t-test).
