Anti-hyperglycemic activity of rutin in streptozotocin-induced diabetic rats: an effect mediated through cytokines, antioxidants and lipid biomarkers

Abstract

Administration of rutin (50 and 100 mg/kg) and pioglitazone (10 mg/kg) orally for 3 weeks treatment significantly improved body weight, reduced plasma glucose and glycosylated hemoglobin, pro-inflammatory cytokines (IL-6 and TNF-alpha), restored the depleted liver antioxidant status and serum lipid profile in high fat diet + streptozotocin induced type 2 diabetic rats. Rutin treatment also improved histo-architecture of beta islets and reversed hypertrophy of hepatocytes. Rutin exhibited significant antidiabetic activity, presumably by inhibiting inflammatory cytokines, improving antioxidant and plasma lipid profiles in High fat diet + streptozotocin induced type 2 diabetic model and may be useful as a diabetic modulator along with standard antidiabetic drugs. However, such effects need to be confirmed on human subjects in clinical condition.
