BACKGROUND AND PURPOSE Quercetin lowers plasma glucose, normalizes glucose tolerance tests and preserves pancreatic β‐cell integrity in diabetic rats. However, its mechanism of action has never been explored insulin‐secreting β‐cells. Using the INS‐1 line, effects quercetin were determined on glucose‐ or glibenclamide‐induced insulin secretion dysfunctions induced by hydrogen peroxide (H 2 O ). These analysed along with activation extracellular signal‐regulated kinase (ERK)1/2 pathway....

The pharmacology of polyphenol metabolites on beta-cell function is largely undetermined. We sought to identify that enhance the insulin-secreting beta-cells and explore underlying mechanisms.INS-1 rat isolated islets Langerhans or perfused pancreas preparations were used for insulin secretion experiments. Molecular modelling, intracellular Ca2+ monitoring, whole-cell patch-clamp recordings mechanistic studies.Among a set metabolites, we found exposure INS-1 urolithins A C enhanced...

We previously showed that grape extracts enriched in different polyphenolic families were similarly able to prevent reactive oxygen species (ROS) production, although having differential effects on various features of metabolic syndrome when administered at a dose 21 mg/kg the fructose (60%)-fed rat (a model syndrome). In present work, we analyzed same effect pure molecules (catechin, resveratrol, delphinidin, and gallic acid) 2.1 mg/kg. Delphinidin acid prevented insulin resistance, while...

Insulin secretion preservation is a major issue for the prevention or treatment of type 2 diabetes. We previously showed on β-cells that quercetin (Q), but not resveratrol (R) N-acetyl cysteine (NAC), amplified glucose-induced insulin in calcium- and ERK1/2-dependent manner. Quercetin, NAC, also protected β-cell function hyperamplified ERK1/2 phosphorylation oxidative stress conditions. As may interfere with other stress-activated protein kinases (JNK p38 MAPK), we further explored MAPK...
