ATP-sensitive K(+) (K(ATP)) channels in pancreatic ?-cells couple glucose
metabolism to insulin secretion. Reduced K(ATP) channel activity produces
excessive insulin release and hyperinsulinism whereas increased K(ATP) channel
activity leads to lower insulin secretion and diabetes. Paradoxically, mice with
genetic deletion of K(ATP) channels, or loss-of-function mutations, are only
transiently hypoglycaemic during the neonatal period and often display reduced
glucose-stimulated insulin secretion subsequently. Mice with K(ATP) channel
gain-of-function mutations are hyperglycaemic and have impaired
glucose-stimulated insulin secretion, a phenotype that accurately mimics human
diabetes. This review discusses how mice expressing altered K(ATP) channels have
provided valuable insight into ?-cell function.
