Abstract:
Aim To study the anti-tumor effect of 20(S)-Protopanaxadiol(PPD)at different concentration on human liver cell line SMMC-7721 in vivo and in vitro.Methods The subcutaneous transplantable tumor model of human liver cancer in nude mice was established and the anti-tumor effect was calculated.Cell growth rate was determined with MTT assay.The apoptosis was analyzed by FITC-AnnexinⅤ/PI and Hoechst33342 staining method,and the activity of Caspase-3 was detected.Results In vivo,PPD could obviously inhibit the growth of transplanted tumor.In vitro,PPD induced inhibition of human liver cancer SMMC-7721 cells was time-dependent and dose-dependent.The apoptotic body was observed by Hoechst33342 staining.PPD could induce cell apoptosis of SMMC-7721,and the increase of Caspase-3 activity was observed in each PPD group.Conclusion PPD could inhibit the growth of human liver cancer SMMC-7721 cells in vivo and in vitro by up-regulating the activity of Caspase-3 and inducing the cell apoptosis.
