ABSTRACT
Objective To observe the effect of Tanshinone ⅡA on proliferation and apoptosis of human gastric adenocarcinoma cell line SGC-7901 and its mechanism.Methods The human gastric adenocarcinoma cell line SGC-7901was cultured in vitro and with Tanshinone ⅡA at various concentrations.Cytotoxicity was valuated by MTT assay,apoptosis-related alterations in morphology were ascertained by transmission electron microscopy.The cell cycle distribution and the apoptotic rate were investigated by flow cytometry.SGC-7901 cell apoptosis with nuclear chromatin concentration and fragmentation as well as cell shrinkage and the formation of apoptotic bodies were observed by TEM.Results The growth of SGC-7901 cells was inhibited significantly in a dose-dependent manner.Tanshinone ⅡA could induce the apoptosis in time-dependent manner.Conclusion Tanshinone ⅡA has effect in inhibiting SGC-7901 cells and inducing the apoptosis.The apoptotic rate and percentage of cells in G1 phase increased in the SGC-7901 cells treated by Tanshinone ⅡA.
