Objective:To evaluate the effects of Polyphyllin I on proliferation and apoptosis of circulating tumor cells (CTC) of lung cancer in vitro. MethodsThe CTC were intervened by Polyphyllin I at different concentrations for 24,8 and 72 hours. The cell proliferation was determined by CCK-8,and the cell apoptosis and cycle were detected by flow cytometry and confocal laser scanning microscopy. Results:Polyphyllin I could significantly inhibit the CTC proliferation in a concentration-dependent manner,and induce the significant morphological changes of CTC nucleus. The proportion of apoptotic cells was significantly increased,and the cells cycle was stagnated in G0/G1 phase. Conclusion:Polyphyllin I can induce CTC apoptosis and inhibit the cells differentiation from G0/G1 to S phase,which plays an anti-tumor effects.
