objective(s):this study examined whether conjugated linoleic acid (cla) supplementation affects insulin sensitivity and peroxisome proliferator-activated receptor gamma (ppar-γ) and glucose transporter type 4 (glut-4) protein expressions in the skeletal muscles of rats during endurance exercise. materials and methods:sprague-dawley male rats were randomly divided into hs (high-fat diet (hfd) se...
Renin-angiotensin-aldosterone system (RAAS) activation mediates increases in reactive oxygen species (ROS) and impaired insulin signaling. The transgenic Ren2 rat manifests increased tissue renin-angiotensin system activity, elevated serum aldosterone, hypertension, and insulin resistance. To explore the role of aldosterone in the pathogenesis of insulin resistance, we investigated the impact o...
Endothelial cell (EC) insulin resistance and dysfunction, caused by diabetes, accelerates atherosclerosis. It is unknown whether specifically enhancing EC-targeted insulin action can decrease atherosclerosis in diabetes. Accordingly, overexpressing insulin receptor substrate-1 (IRS1) in the endothelia of Apoe-/- mice (Irs1/Apoe-/-) increased insulin signaling and function in the aorta. Atherosc...
We have investigated the acute regulation by insulin of the mRNA levels of nine genes involved in insulin action, in muscle biopsies obtained before and at the end of a 3-h euglycemic hyperinsulinemic clamp. Using reverse transcription-competitive PCR, we have measured the mRNAs encoding the two insulin receptor variants, the insulin receptor substrate-1, the p85alpha subunit of phosphatidylino...
Objective: MafA has been recognized as a specific pancreatic β-cells activator for Insulin expression. This study investigated the changes in glucose transport and consumption by MafA-positive Insulin-producing cells resulting from differentiation of rat adipose tissue-derived mesenchymal stem cells. Methods: Adipose were differentiated into 14-day protocol using nicotinamide ITS. The ability t...
Wu-Mei-Wan Reduces Insulin Resistance via Inhibition of NLRP3 Inflammasome Activation in HepG2 Cells
Wu-Mei-Wan (WMW) is a Chinese herbal formula used to treat type 2 diabetes. In this study, we aimed to explore the effects and mechanisms of WMW on insulin resistance in HepG2 cells. HepG2 cells were pretreated with palmitate (0.25 mM) to impair the insulin signaling pathway. Then, they were treated with different doses of WMW-containing medicated serum and stimulated with 100 nM insulin. Resul...
Evidence demonstrates that exogenous nitric oxide (NO) and the NO produced by inducible nitric oxide synthase (iNOS) can induce insulin resistance in muscle. Here, we investigated whether this insulin resistance could be mediated by S-nitrosation of proteins involved in early steps of the insulin signal transduction pathway. Exogenous NO donated by S-nitrosoglutathione (GSNO) induced in vitro a...
Adipose tissue may be the source of insulin desensitizing proinflammatory molecules that predispose to insulin resistance. This study investigated whether dietary fatty acids could attenuate the proinflammatory insulin-resistant state in obese adipose tissue. The potential antidiabetic effect of cis-9, trans-11-conjugated linoleic acid (c9,t11-CLA) was determined, focusing on the molecular mark...
