Purpose : This study was conducted to investigate the inhibitory effects of Cortex ulmi pumilae on cell proliferation in HeLa cell.
Methods : Human uterine cervical carcinoma HeLa cells were cultured in the 1%, 5% and 10% concentration of Cortex ulmi pumilae solution for 24 hours, 48 hours and 72 hours for the direct inhibitory effects of Cortex ulmi pumilae. Afterwards, we executed the analysis of the effect of Cortex ulmi pumilae solution on cell proliferation inhibition using XTT assay, DNA fragmentation, molecular biological method through MAP kinase activity and FACS analysis of caspase activity in the HeLa cells.
Results : After 48 and 72 hours cultivation, the HeLa cells showed the concentration-dependently significant increase in all Cortex ulmi pumilae solution containing groups compared to the control. In the FACS analysis, all Cortex ulmi pumilae solution containing groups showed concentration-dependent increase compared to the control after 24 hours cultivation and the caspase-3 activities were decreased in all Cortex ulmi pumilae solution containing groups compared to the control after 24, 48 and 72 hours cultivation. After 48 and 72 hours cultivation, we could examined the apparent DNA fragmentation in all Cortex ulmi pumilae solution containing groups. In the XTT study, all Cortex ulmi pumilae solution containing groups showed concentration-dependent decrease compared to the control after 24 and 72 hours cultivation but 10% group after 48 hours and 5% and 10% groups after 72hours were presumed statistically significant differences. The expressions of MAP kinase were decreased in all Cortex ulmi pumilae solution containing groups compared to the control after 24, 48 and 72 hours cultivation.
Conclusion : From this study we could suggest that Cortex ulmi pumilae be available to the inhibition of apoptosis of human cervical carcinoma cell line in vitro.
