Abstract

Background/aims Resveratrol, a polyphenolic activator of the silent information regulation 2 homolog 1 (SIRT1), is known to extend lifespan and improve metabolic disease. The aim of the present study is to test whether resveratrol protects against metabolic steatohepatitis through the modulation of lipid metabolism-related genes.Methods We used a mouse model in which steatohepatitis can be induced by an atherogenic diet (Ath diet) to evaluate the effects of resveratrol on steatotic hepatitis and hepatic gene expression.Results The Ath diet induced excessive weight gain, hepatomegaly, dyslipidemia, and steatohepatitis after 8 weeks. The addition of resveratrol protected against Ath diet-induced changes and also alleviated steatohepatitis. Whole-genome expression analysis revealed that an Ath diet altered the hepatic expression of genes involved in lipid metabolism, and the addition of resveratrol to the diet reversed that effect. Real-time PCR and Western blot analysis confirmed the Ath diet up-regulated the levels of genes related to lipogenesis and down-regulated genes involved in lipolysis. Resveratrol clearly suppressed the Ath diet-induced alterations of the expression of genes related to lipid metabolism.Conclusions Resveratrol ameliorated dyslipidemia and steatohepatitis induced by the Ath diet, and its beneficial effects were associated with the altered expression of hepatic genes involved in lipid metabolism.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
