Cycle Arrest

Prostate cancer is the most common cancer in Western countries. Recently, Asian countries are being affected by Western habits, which have had an important role in the rapid increase in cancer incidence. Sanggenol L (San L) is a natural flavonoid present in the root barks of Morus alba, which induces anti-cancer activities in ovarian cancer cells. However, the molecular and cellular mechanisms of the effects of sanggenol L on human prostate cancer cells have not been elucidated. In this study, we investigated whether sanggenol L exerts anti-cancer activity in human prostate cancer cells via apoptosis and cell cycle arrest. Sanggenol L induced caspase-dependent apoptosis (up-regulation of PARP and Bax or down-regulation of procaspase-3, -8, -9, Bid, and Bcl-2), induction of caspase-independent apoptosis (up-regulation of AIF and Endo G on cytosol), suppression of cell cycle (down-regulation of CDK1/2, CDK4, CDK6, cyclin D1, cyclin E, cyclin A, and cyclin B1 or up-regulation of p53 and p21), and inhibition of PI3K/Akt/mTOR signaling (down-regulation of PI3K, p-Akt, and p-mTOR) in prostate cancer cells. These results suggest the induction of apoptosis via suppression of PI3K/Akt/mTOR signaling and cell cycle arrest via activation of p53 in response to sanggenol L in prostate cancer cells.
