Abstract

Objective : The aim of this study is to evaluate anti-cancer effects of $Ampelopsisradix$ Extract (AE) on human lung cancer A549 cells. Method : The apoptotic activities and cell growth arrest activities of AE were measured using 3-[4,5-dimethyl-thiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. The molecules involved in apoptotic process were assessed by western blotting. Result : Treatment of AE potently reduced cell viability in a dose-dependent manner in A549 cells. AE (100-500 ${\mu}g/m{\ell}$) resulted in apoptosis via activation of caspase 9 following PARP cleavage in a time-and dose-dependent manner. The levels of Bax and Bad levels were increased by AE with a concomitant decrease of Bcl-xL. In addition, AE at the low dose (30 ${\mu}g/m{\ell}$) significantly inhibited cell growth in the presence of serum. Conclusion : AE has the potential as a therapeutic agent against lung cancer.
