The mechanisms of apoptosis induced by curcumin in gastric cancer cells / 肿瘤研究与临床

ABSTRACT

Objective To study the mechanisms of Curcumin-induced apoptosis on human gastric cancer cell line SGC-7901.Methods SC,C-7901 cells were treated with various concentrations of Curcumin and the growth inhibition rates of it were accessed by MTT method.Apoptosis of gastric cancer cells were in- spected by flow cytometry.The expression of Fas and survivin in gastric cancer cells were evaluated by west- ern blot.Results Curcumin could effectively inhibit the growth of gastric cancer cells in dose-dependent and time-dependent manners,the sub-peak appeared and the apoptotic rate was increased.The expressions of Fas was higher in Western blot,meanwhile,the expressions of survivin was decreased.Conclusion Curcumin could significantly inhibit the growth and induce apoptosis of gastric cancer cells(SGC-7901),Curcumin could probably through up-regulating Fas and down-regulating surviving to induce apoptosis.
