Abstract:
BACKGROUND:Phytoestrogens are known to prevent tumor induction. But their molecular mechanisms of action are largely unknown. This study aimed to examine the effect of genistein and quercetin on proliferation and apoptosis in HER2-expressing breast cancer cells. MATERIALS AND METHODS:The antiproliferative effects of phytoestrogens were tested by proliferation assays. Flow cytometry was performed to analyze the cell cycle. The effect of phytoestrogens on cell-signaling molecules was determined by Western blotting. RESULTS:Genistein and quercetin inhibited the proliferation of MCF-7 vec and MCF-7 HER2 cells. This growth inhibition was accompanied with an increase of subG(0)/G(1) apoptotic fractions. Genistein and quercetin induced extrinsic apoptosis pathway, up-regulating p53. Genistein and quercetin reduced the phosphorylation level of IκBα, and abrogated the nuclear translocation of p65 and its phosphorylation within the nucleus. CONCLUSION:Genistein and quercetin exert their antiproliferative activity by inhibiting NFκB signaling. Phytoestrogens could be potential useful compounds to prevent or treat HER2-overexpressing breast cancer.
