Targeting SUR1/Abcc8-type neuroendocrine KATP channels in pancreatic islet cells.

Abstract excerpt

ATP-sensitive K+ (KATP) channels play a regulatory role in hormone-secreting pancreatic islet α-, β- and δ-cells. Targeted channel deletion would assist analysis and dissection of the intraislet regulatory network. Toward this end Abcc8/Sur1 flox mice were generated and tested by crossing with glucagon-(GCG)-cre mice to target α-cell KATP channels selectively. Agonist resistance was used to quantify the percent...
