    Abstract:
    Ginkgetin is a natural biflavonoid isolated from leaves of Ginkgo biloba L. Though it was known to have anti-inflammatory, anti-influenza virus, anti-fungal activity, osteoblast differentiation stimulating activity and neuro-protective effects, the underlying antitumor mechanism of ginkgetin still remains unclear. Thus, in the present study, anti-cancer mechanism of ginkgetin was elucidated in human prostate cancer PC-3 cells. Ginkgetin suppressed the viability of PC-3 cells in a concentration-dependent manner and also significantly increased the sub-G1 DNA contents of cell cycle in PC-3 cells. Ginkgetin activated caspase-3 and attenuated the expression of survival genes such as Bcl-2, Bcl-xL, survivin and Cyclin D1 at protein and mRNA levels. Consistently, pan-caspase inhibitor Z-DEVD-fmk blocked sub G1 accumulation and cleavages of PRAP and caspase 3 induced by ginkgetin in PC-3 cells. Overall, these findings suggest that ginkgetin induces apoptosis in PC-3 cells via activation of caspase 3 and inhibition of survival genes as a potent chemotherapeutic agent for prostate cancer treatment.
