The resulting boost in intracellular calcium triggers the release of insulin granules. Secretion terminates when the beta cell is repolarized by the opening of potassium channels like members in the voltage- (Kv) and calcium-activated (KCa) potassium channel households (Braun et al, 2008; Houamed et al, 2010; Jacobson et al, 2010). Thus, the quantity of insulin secreted is directly coupled to the electrical activity of the beta cell, and modulation in the several ion channels involved delivers distinct options for the remedy of glucose homeostasis connected issues like diabetes. Because KATP channels constitute crucial initiators of glucose-stimulated insulin secretion (GSIS), good work has been devoted towards the study of anti-diabetic drugs just like the sulfonylureas, which modulate certainly one of the two molecular elements in the KATP channel (Bryan et al, 2005; Proks et al, 2002). Even so, an issue commonly linked with such drugs is the fact that KATP present inhibition is independent in the basal glucose levels and hypoglycemia is often observed (Amiel et al, 2008; Stahl Berger, 1999). Representatives of most K channel households have been identified in pancreatic islets, and specifically in beta cells. Nevertheless, the molecular identities of these voltage-gated2012 EMBO Molecular MedicineEMBO Mol Med 4, 424www.embomolmed.orgResearch ArticleRocio K. Finol-Urdaneta et al.potassium channels (Kv channels) involved in the regulation of GSIS remain obscure. Biophysical properties, with each other with dominant-negative knockdown and pharmacological inhibition, suggest that Kv1 channels account for 25 of beta cell delayed rectifier currents, whereas Kv2 channels account for 60 ; furthermore, inhibition of those Kv ch.
