Chronic elevations in plasma levels of fatty acids (FAs) adversely affect pancreatic beta-cell function in type 2 diabetes. In vitro, we have previously shown that deleterious effects of prolonged exposure of isolated islets to FAs were dependent on the presence

Nitric oxide (NO) has been proposed as a possible mediator of beta-cell damage in human IDDM. This hypothesis is based on in vitro studies with rodent pancreatic islets. In the present study we examined whether human beta-cells are affected by

Rats were fasted for 48 h, but infused with either NaCl or the sodium salt of monoethyl succinic acid (EMS), both delivered at a rate of 80 mumol/g body weight per day. The infusion of EMS, as compared to NaCl

The involvement of phosphatidylcholine (PC) hydrolysis in the regulation of insulin secretion was studied in mouse pancreatic islets prelabelled with [3H]choline. Phospholipase C (PLC) and phospholipase D (PLD) activities were demonstrated and also that of an enzyme that removes both
The Biochemical journal, 403(1), 197-205 (2006-12-22)
The present study was undertaken to determine the main metabolic secretory signals generated by the mitochondrial substrate MeS (methyl succinate) compared with glucose in mouse and rat islets and to understand the differences. Glycolysis and mitochondrial metabolism both have key
