From: Gambogenic acid alters chemosensitivity of breast cancer cells to Adriamycin
MCF-7 and MCF-7/ADR cell lines treated with ADR + GNA showed up-regulated expression of caspase-3 and caspase-9. a and b Using either 0.3125 μg/ml GNA, 20 μg/ml ADR or the combined use of both ADR and GNA for 72 h, we used antibodies against caspase-3 and caspase-9 and analyzed the expression of caspase proteins by the western blot technique. β-actin was used as an internal control.
