Induction of apoptosis in human ovarian cancer cell lines A2780 (A) and C200 (B) treated with genistein (Gen), cisplatin (Cis), gemcitabine (Gem) and taxotere (Tax) alone and the combination treatments were evaluated by the ELISA assay. A2780 cells were treated with genistein (10 μM), cisplatin (250 nM), gemcitabine (2 nM) and taxotere (1 nM) and the combination treatment; and the C200 cells were treated with higher doses of genistein (25 μM), gemcitabine (50 nM) and doxetaxel (2 nM) as described under Materials and Methods. There was a significant potentiation in the induction of apoptosis observed in A2780 and C200 cells treated with both genistein and the other drugs as compared to cells treated with either agent alone.
