Dendrobium officinale polysaccharide ameliorates high-fat diet-induced hepatic lipid metabolic disorder via the SIRT6/PGC-1α signaling axis (opens in new tab)

AimsThis study aims to explore the potential therapeutic effect of Dendrobium officinale polysaccharide (DOP) on non-alcoholic fatty liver disease (NAFLD) induced by high-fat diet (HFD), and to elucidate the underlying mechanism involving the SIRT6/PGC-1α signaling axis and the regulation of the gut microbiota.MethodsWe extracted and characterized DOP. We established a rat model of NAFLD induced by HFD and evaluated the efficacy of DOP by integrating multi-omics techniques (transcriptomics, m...
