[Abstract] Objective To study the effects of mangiferin on cell apoptosis and intracellular Ca2+ (IECa2+)concentration in nasopharyngeal carcinoma CNE3 cells in vitro.Methods After CNE3 cells were treated with different concentrations of mangiferin for 24,48 and 72 hours, the apoptosis ratio and changes of IECa2+ were assessed by flow cytometry.Results (1)After 24,48 and 72 hours of mangiferin administration, the different concentrations of mangiferin can induced the CNE3 cells apoptosis and the effect were dependent on time and concentration; (2)After CNE3 cells were treated with mangiferin for 24,48 and 72 hours, IECa2+ were significantly increased, and the effect were dependent on time and concentration.Conclusion Mangiferin can markedly induce apoptosis in CNE3 cell, and the increase of IECa2+ may play an important role to the induce apoptosis of mangiferin. |
