Purpose: This study was conducted to investigate the effects of Cervi Pontotrichum Cornu extract solution on the cell cycle regulation and apoptosis in human leiomyoma cell. Methods: The leiomyoma cell of patients was used in the study, and we administered the extract solution of Cervi Pontotrichum Cornu concentration at 1, $10mg/m{ell}$ to the leiomyoma cell for 48 hours. We used flow cytometry and western blotting to confirm cell cycle and apoptosis. Results: In flow cytometry, G1 phase of the $1mg/m{ell}$ group prolonged. But G1 phase of $10mg/m{ell}$ group was shortened and S phase was increased. Cyclin D1 expression increased in higher concentration group. And Bax expression that regulates cell apoptosis increased in $1mg/m{ell}$ and $10mg/m{ell}$ group than control group. Bcl-2 expression decreased in 1, $10mg/m{ell}$ groups than control group. VEGF expression rised in higher Cervi Pontotrichum Cornu concentration group. Conclusion: This study means that Cervi Pontotrichum Cornu could induce the apoptosis of leiomyoma cell by increasing Bax and decreasing Bcl-2 expression. But Cervi Pontotrichum Cornu could increase Cyclin D1 and VEGF expression, so more detailed studies would be needed.
