Abstract

Resveratrol is an antioxidant present in grapes and their related products. We investigated whether dietary resveratrol could inhibit the proliferation and metastasis of tumors and hyperlipidemia in Donryu rats subcutaneously implanted with an ascites hepatoma cell line of AH109A. By feeding 10 or 50 ppm resveratrol in the diet to hepatoma-bearing rats for 20 days, solid tumor growth and metastasis tended to be suppressed dose-dependently. Resveratrol (50 ppm) significantly suppressed the serum lipid peroxide level, indicating its antioxidative properties or those of its metabolite(s) in vivo. Resveratrol dose-dependently suppressed both the serum triglyceride and very-low-density lipoprotein + low-density lipoprotein (VLDL + LDL)-cholesterol levels. The hypocholesterolemic action of resveratrol is attributed, at least in part, to an increased excretion of neutral sterols and bile acids into feces. These results suggest that dietary resveratrol is hypolipidemic with a tendency for anti-tumor-growth and anti-metastasis effects in hepatoma-bearing rats.
