  • Title: Inhibitory effects of schisantherin F from Schisandra propinqua subsp. sinensis on human melanoma A375 cells through ROS-induced mitochondrial dysfunction and mitochondria-mediated apoptosis.

    Abstract:
    Schisandra propinqua subsp. sinensis is a traditional medicinal plant used in Chinese folk medicine. Melanoma is the most dangerous form of skin cancer. To discover bioactive phytochemicals for preventing human melanoma, we have investigated the inhibitory effects of schisantherin F in Schisandra propinqua subsp. sinensis on human melanoma A375 cells and relevant mechanisms. The results showed that schisantherin F can inhibit A375 cells through inducing apoptosis. Further investigations have demonstrated schisantherin F attenuated the overproduction of ROS, depolarization of MMP, and mPTP opening. Meanwhile, schisantherin F inhibited the activity of Caspase-3 and up-stream Caspase-9, down-regulated Bcl-2 and up-regulated Bax. These findings propose the inhibitory mechanisms of schisantherin F in A375 cells include induction of mitochondrial dysfunction and mitochondria-mediated apoptosis.
