To study mechanism of resveratrol induce HepG-2 apoptosis via Ca2+ and ROS pathway. Measurements using mononuclear cell direct cytotoxicity assay(the MTT method) shows that its cytotoxic effect on HepG-2 is strong with IC50 being 34.86 μmol·L-1. Measurement of action of apoptosis using morphology show that karyoplasmic ratio of tumor cell become diminish, Cells break up into several apoptotic bodies of different sizes. Measurement rate of apoptosis and cell cycle dealed with RES using flow cytometry shows that RES leads to a decrease in the proportion of cells in G0/G1 phase, an increasement in proportion of cells in S phase and decrease in proportion of cells in G2/M phase. Rates of apoptosis induced by RES are 26.130%, 31.599%, 65.655%. Measurement Ca2+ content in HepG-2 treated with RES using laser scanning confocal microscope with Fluo-3 stain shows that RES can obviously increase Ca2+ content. Measurement content of ROS in HepG-2 treated with RES shows that RES can enhance the content of ROS. RES can induce HepG-2 apoptosis and activate Ca2+ and ROS signaling pathway.
