abstract = {AIM: To study the effect of rosiglitazone (RSG) on insulin secretion in isolated pancreatic islets under chronic exposure to free fatty acid (FFA) and to investigate the potential signaling mechanism of RSG action. METHODS: Rat pancreatic islets were cultured with or without FFA (2 mmol/L, oleate:palmitate, 2:1) in the presence or absence of RSG (0.05-10 micromol/L). The insulin release was measured by radioimmuoassay, the expression level of insulin receptor substrate-2 (IRS-2) protein and the association of IRS-2 with p85 subunit of phosphatidylinositol 3-kinase (PI 3-kinase) were determined by immunoprecipitation and Western blot. RESULTS: The islets exposed to high FFA concentration showed an increased basal and a decreased glucose-induced insulin release as compared with control islets (P},
