Effect of embelin on the expression levels of MCF-7 breast cancer cell apoptosis-related proteins, including procaspase-3, -8 and -9, 48 h following the treatment of MCF-7 breast cancer cells with different concentrations of embelin (0, 40 and 80 μg/ml). (A) Western blot analysis was used to analyze the expression of procaspase-3, -8 and -9 proteins. (B) The western blot analysis results were further analyzed using Gel-Pro Analyzer 4.0 software. ^*P<0.05 vs. control. Results are representative of three independent experiments.
