Vineatrol and cardiovascular disease: beneficial effects of a vine-shoot phenolic extract in a hamster atherosclerosis model.

Abstract

We evaluated the effect of the intake of a grapevine-shoot phenolic extract (Vineatrol 30) on early atherosclerosis in hamsters fed a hyperlipidic diet. Golden Syrian hamsters received for 13 weeks either a standard diet, a high-fat (HF) diet, or the HF diet plus Vineatrol 30 at 0.04, 0.2, or 1.0 mg/(kg body weight/d). We measured plasma lipids and glucose, insulin, leptin and adiponectin, as well as liver TNF-α and IL-6 levels. Oxidative stress was assessed by measuring plasma paraoxonase activity (PON) and liver superoxide anion production (O(2)(•-)). The aortic fatty streak area (AFSA) was also determined. In comparison with HF group, we demonstrated that the highest dose of Vineatrol 30 was capable of decreasing AFSA (67%), insulinemia (40%), and leptinemia (8.7%), which were increased by the HF diet. We also showed increased O(2)(•-) production (35%) and a rise in levels of the liver proinflammatory cytokines TNF-α (22%) and IL-6 (21%), accompanied by a fall in PON activity (56%) due to the HF diet versus the standard diet. In contrast, except plasma adiponectin levels that are not changed, Vineatrol 30 treatment lowered AFSA (67%), O(2)(•-) production (36%), insulin resistance (42%), leptinemia (9%), liver TNF-α (18%) and IL-6 (15%), while it rose PON activity (29%). These findings demonstrate the preventive effects of polyphenols present in Vineatrol 30 in managing cardiovascular, metabolic, and inflammatory risk factors.
