['Insulin resistance is a major factor in the development of metabolic syndrome and is associated with central obesity and glucose intolerance. Resveratrol, a polyphenol found in fruits, has been shown to improve metabolic conditions. Although it has been widely studied how resveratrol affects metabolism, little is known about how resveratrol regulates lipogenesis with insulin signaling in 3T3-L1 adipocytes.', 'We treated differentiated 3T3-L1 adipocytes with resveratrol to observe whether resveratrol is effective at reducing lipid accumulation.', 'Resveratrol treatment after mitotic clonal expansion resulted in decreased lipid accumulation accompanied by reduced fatty acid synthase expression. Decreased glucose uptake was observed with inhibited GLUT4 translocation in cells treated with 100 μM resveratrol, suggesting that high doses of resveratrol block insulin signaling in adipocytes. Insulin-stimulated Akt phosphorylation is also dose-dependently reduced with resveratrol treatment. Interestingly, Akt phosphorylation is upregulated when cells are treated with long-term low doses of resveratrol, suggesting that only low doses of resveratrol improve metabolic conditions.'] Does high-dose Resveratrol inhibit Insulin Signaling Pathway in 3T3-L1 Adipocytes?
