Abstract

Objectives: This study was conducted to investigate the inhibitory effects of Gaejibokryunghwan on cell proliferation in HeLa cells. Materials and Methods: Human uterine cervical carcinoma HeLa cells were cultured in the 1%, 5% and 10% concentration of Gaejibokryunghwan extract solution. All three were cultured for 24 hours, 48 hours and 72 hours each, to examine the inhibitory effects of Gaejibokryunghwan. Afterwards, we drew out the effect of Gaejibokryunghwan extract solution by making 5 analysis. First analysis was to measure the proliferation rate of cells. Second was FACS analysis. Third was to estimate the activity of caspase-3. Fourth, we used XTT assay to analyze the activation of cells. And lastly, a molecular biological method was used to determine activation of MAP kinase in the HeLa cells. Results: After 24, 48 and 72 hours cultivation, the proliferation of HeLa cells showed the dose-dependent decrease in all Gaejibokryunghwan extract solution groups compared to the control group. In the FACS analysis, Gaejibokryunghwan extract solution groups showed increased caspase expression compared to the control group, except for the group for 48 and 72 hours in 1% concentrate. Caspase-3 activities were increased in all, except the group cultured for 24 hours in 5% concentrate and the groups cultured for 48 hours in 1% and 5% concentrate. In the XTT study, 1% Gaejibokryunghwan extract solution groups showed increase compared to the control group, but other Gaejibokryunghwan extract solution containing groups showed significant decrease compared to the control after 24, 48 and 72 hours of cultivation. The expressions of MAP kinase were decreased in all Gaejibokryunghwan extract solution containing groups compared to the control group after 24, 48 and 72 hours of cultivation. Conclusion: From this study, we could suggest that Gaejibokryunghwan be available to the inhibition of proliferation of human cervical carcinoma cell line, HeLa cells in vitro.
