Modulation of dihydropyridine-sensitive Ca2+ channels by glucose metabolism in mouse pancreatic beta-cells.
Glucose stimulates insulin secretion from the pancreatic beta-cell by increasing the cytosolic calcium concentration. It is believed that this increment results mainly from Ca2+ influx through dihydropyridine-sensitive calcium channels because insulin secretion is abolished by dihydropyridine antagonists and is potentiated by dihydropyridine agonists. Glucose may influence Ca2+ influx through these channels in two ways: either by regulating the beta-cell membrane potential or by biochemical m...Expand abstract
