S.C triggers intrinsic apoptosis in prostate cancer cell. After the cells were treated with 1.0 μM S.C for 48 h, apoptosis rate of VCaP a, b, PC3 c, d and DU145 e, f cells was detected by flow cytometry. After the cells were treated with 0, 0.5,1.0 μM S.C for 24 h or 48 h, Hoechst 33,258 staining was used to observe the morphological changes of PC3 g and DU145 h cells. Intrinsic and extrinsic apoptosis related proteins level in PC3 i and DU145 j cells receiving 0, 0.5,1.0 μM S.C treatments for 48 h
