Purpose : This study was conducted to investigate the inhibitory effects of Dangguijakyaksan on cell proliferation in HeLa cells. Methods : Human uterine cervical carcinoma HeLa cells were cultured in the 1%, 5% and 10% concentration of Dangguijakyaksan extract solution for 24 hours, 48 hours and 72 hours for the direct inhibitory effects of Dangguijakyaksan. Afterwards, we executed the analysis of the effect of Dangguijakyaksan extract solution on cell proliferation inhibition using XTT assay, molecular biological method through MAP kinase activity and FACS analysis of caspase activity in the HeLa cells. Results : After 24, 48 and 72 hours cultivation, Dangguijakyaksan extract solution group showed significant decrease of HeLa cells except 1% solution after 24 hours compared with the control group. In the FACS analysis, Dangguijakyaksan extract solution groups showed increase of caspase activity except 1% solution after 48 hours compared with the control group. In the XTT assay, the caspase-3 activities were increased in Dangguijakyaksan extract solution groups except 1% solution after 24 hours in a dose-dependent manner. In the XTT study, cell activities were significantly decreased in 10% Dangguijakyaksan extract solution groups after 48 and 72 hours cultivation compared with the control group. In all Dangguijakyaksan extract solution groups, The activities of MAP kinase were decreased after 24, 48 and 72 hours cultivation compared with the control group. Conclusion : It could be concluded that Dangguijakyaksan is available to the inhibition of proliferation of human cervical carcinoma cell line in vitro.
