| Abstract: | Objective To investigate whether chrysin(ChR) sensitizes TRAIL-induced apoptosis in human gastric cancer SGC-7901 cell line.Methods Human gastric cancer SGC-7901 cell line was cultured in vitro.The cell apoptosis rate was examined by flow cytometry using PI fluorescence staining.DNA fragmentation was detected by DNA agarose gel electrophoresis.Results The apoptosis rate in human gastric cancer SGC-7901 cells treated by ChR(40μmol/L) or TRAIL(100ng/mL) or both were(4.57±0.54)%,(3.70±0.17)% and(48.81±4.11)%,respectively.The obvious fragmentation DNA was observed in combination of ChR and TRAIL.Conclusion ChR at suboptimal concentration sensitizes TRAIL-induced apoptosis in human gastric cancer SGC-7901 cells. |
