Resveratrol inhibits VEGF gene expression and proliferation of hepatocarcinoma cells.

Background/Aims: Resveratrol is known to have potent anti-inflammatory and antioxidant effects and to inhibit platelet aggregation and growth of a variety of cancer cells. In the paper, we investigated the effects of Resveratrol (Res) on expression of VEGF gene inhuman hepatocarcinoma cell cells and cell proliferation. Methodology: HepG2 cells were treated with different concentrations of Res (0, 10, 20, 40 mu mol/L) and different title (24, 48,72h). Cell proliferation was examined by MTT method and the expression of VEGF gene was analyzed by RT-PCR and Western blot. Results: Res could inhibit expression of VEGF gene, the inhibitory effect of Res increased with the increasing of concentration of Res and treatment time., Conclusions: Our results suggest that Res can significantly inhibit the proliferation of HepG2 cells and exerts an anti-tumor effect by repressing the expression of VEGF gene.
