Free fatty acids induce peripheral insulin resistance without increasing muscle hexosamine pathway product levels in rats.
To evaluate the role of the hexosamine biosynthesis pathway (HBP) in fat-induced insulin resistance, we examined whether fat-induced insulin resistance is additive to that induced by increased HBP flux via glucosamine infusion and, if so, whether such additive effects correlate with muscle HBP product levels. Prolonged hyperinsulinemic (approximately 550 pmol/l) euglycemic clamps were conducted...
متن کاملThe Effects of Simvastatin on Free Fatty Acids Profile in Fructose-fed Insulin Resistant Rats
Backgrounds: Type 2 diabetes mellitus is the most common metabolic disease and free fatty acids, as signaling molecules, can play a crucial role in the development of it. Different free fatty acids, through various cell membrane receptors, induce different effects on metabolic pathways and thereby affect insulin sensitivity. Simvastatin is a cholesterol decreasing drug prescrib...
متن کاملFree fatty acids increase basal hepatic glucose production and induce hepatic insulin resistance at different sites.
To investigate the sites of the free fatty acid (FFA) effects to increase basal hepatic glucose production and to impair hepatic insulin action, we performed 2-h and 7-h Intralipid + heparin (IH) and saline infusions in the basal fasting state and during hyperinsulinemic clamps in overnight-fasted rats. We measured endogenous glucose production (EGP), total glucose output (TGO, the flux through...
متن کاملAMP kinase activation ameliorates insulin resistance induced by free fatty acids in rat skeletal muscle.
We examined whether acute activation of 5'-AMP-activated protein kinase (AMPK) by 5'-aminoimidazole-4-carboxamide-1-beta-D-ribonucleoside (AICAR) ameliorates insulin resistance in isolated rat skeletal muscle. Insulin resistance was induced in extensor digitorum longus (EDL) muscles by prolonged exposure to 1.6 mM palmitate, which inhibited insulin-stimulated glycogen synthesis to 51% of contro...
متن کاملSaturated free fatty acids induce cholangiocyte lipoapoptosis.
UNLABELLED Recent studies have identified a cholestatic variant of nonalcoholic fatty liver disease (NAFLD) with portal inflammation and ductular reaction. Based on reports of biliary damage, as well as increased circulating free fatty acids (FFAs) in NAFLD, we hypothesized the involvement of cholangiocyte lipoapoptosis as a mechanism of cellular injury. Here, we demonstrate that the saturated ...
