[Method] Hep G2 cells were treated with GPS for 48 h for morphology assay by transition electron microscope. Anti-proliferative effects with the same treatment for 24 hand 48 h were assayed by MTT method.Cell cycle distribution and apoptosis assay of treated cells were performed in flow cytometry. [Result] The results showed that GPS enhanced growth inhibitory effect on Hep G2 cells in a time-and dose-dependent manner. PI(Propidium iodide)/Annexin V staining analyzed by FCM(flow cytometry) demonstrated that GPS has a cytotoxic effect on tumor cells. Cell cycle arrest of Hep G2 treated with GPS occurred in G2 phase. [Conclusion] This study suggests that GPS could exert an antitumor effect and could be used as a therapeutic agent for live cancer.展开更多
