Objective To investigate the effects of radiotherapy combined with resveratrol( Res)on proliferation, invasion and apoptosis of hepatoma cell line Bel-7404. Methods Bel-7404 cell line was treated with Res(25 μmol·L-1 ) combined with radiotherapy,then divided into four groups( group 1:the control;group 2:radiation at dose of 2 Gy;group 3:radiation at dose of 4 Gy;group 4:radiation at dose of 6 Gy). Cell proliferation and invasion were detected by MTT assay. Cell apoptosis were observed by fluorescence microscopy. Expressions of MMP-2 and VEGF proteins were determined by Western blotting. Results Compared with the control group,cell proliferation and invasion were significantly inhibited,while cell apoptosis was increased in all radiation groups(P〈0. 05). Conclusion The sensitivity of hepatoma Bel-7404 cells to radiation can be enhanced by resveratrol. Radiation therapy combined with resveratrol can inhibit proliferation and invasion of hepatoma cells and increase the cell apoptosis,which may be related with the down-regulation of MMP-2 and VEGF proteins.
