Abstract

Aim: To investigate the effects of genistein on cell apoptosis in the human gastric cancer cell BGC- 823 and the potential regulation pathway involved in its apoptotic effect.Methods: Effects of genistein on the proliferation, cell cycle progression and apoptosis of gastric cancer cells were examined in vitro. Western blotting were applied to analyze the proteins associated with the biological effects of genistein.Results: Gastric cancer cell growth was attenuated by genistein treatment in dose- and timedependent manner. Cell cycle progression analysis showed that apoptosis was enhanced in genistein treated cells and cell cycle arrest at G2/M phase. Increased apoptosis was accompanied by increased level of caspase-3 protein and decreased level of Bcl-2 protein.Conclusions: Genistein induce the apoptosis of BGC-823 in dose- and time-dependent manner. This apoptosis may be mediated by down-regulating the apoptosis-associated Bcl-2 gene and upregulating the expression of apoptosis-associated caspase-3 gene. As genistein was effective in vitro in promotion of apoptosis of gastric cancer cell by caspase-3 and Bcl-2 related apoptotic pathway, it might be a potential therapeutic agent against gastric cancer.
