[Effects of natural plant ginkgolic acids on the apoptosis of human Hep-2 cancer cells].

To investigate the anti-cancer effects and mechanism of natural plant ginkgolic acids (GAs) on Human Hep-2 cancer cells. Hep-2 cancer cells were treated with different concentration of GAs for different times. The proliferation of Hep-2 cancer cells were detected by MTT colorimetric assay. Biochemistry characteristics of cell apoptosis was analyzed by DNA agarose electrophoresis and FCM. The proliferation of Hep-2 cancer cells were inhibited significantly by GAs in a dose and time-dependent manner. Typical DNA ladder bands of Hep-2 cell DNA treated with GAs were observed on agarose electrophoresis gels. Increased apoptosis of Hep-2 cells treated with GAs was also noticed with FCM analysis. Ginkgolic acids show an anti-tumor activity through inhibition the growth and inducing apoptosis of tumor cell in vitro.
