Stoichiometry of sulfonylurea-induced ATP-sensitive potassium channel closure.
Hypoglycemic sulfonylureas (e.g., glibenclamide, glipizide, and tolbutamide) exert their stimulatory effect on excitatory cells by closure of ATP-sensitive potassium (KATP) channels. These channels are heteromultimers composed with a 4:4 stoichiometry of an inwardly rectifying K+ channel (KIR) subunit 6.x plus a sulfonylurea receptor (SUR). SUR1/KIR6.2 reconstitutes the neuronal/pancreatic beta...
متن کاملMechanisms of action of various ATP-sensitive potassium channel openers.
Dr. Grover’s very kind and complimentary remarks about the recent review [l] on ATP-sensitive potassium channel openers during ischemia and reperfusion are much appreciated. One point, however, causes Dr. Grover considerable concern-this is the citation of (and by implication a presumed agreement with) the comments in the paper by Richer et al. [2]. This paper was critical of the conclusions of...
متن کاملStructure of a Pancreatic ATP-Sensitive Potassium Channel
ATP-sensitive potassium channels (KATP) couple intracellular ATP levels with membrane excitability. These channels play crucial roles in many essential physiological processes and have been implicated extensively in a spectrum of metabolic diseases and disorders. To gain insight into the mechanism of KATP, we elucidated the structure of a hetero-octameric pancreatic KATP channel in complex with...
متن کاملDual regulation of the ATP-sensitive potassium channel by caffeine.
ATP-sensitive potassium (K(ATP)) channels couple cellular metabolic status to changes in membrane electrical properties. Caffeine (1,2,7-trimethylxanthine) has been shown to inhibit several ion channels; however, how caffeine regulates K(ATP) channels was not well understood. By performing single-channel recordings in the cell-attached configuration, we found that bath application of caffeine s...
متن کاملCardioprotective effects mitochondrial ATP-sensitive potassium channel in exercise conditioning.
We investigated the mitochondrial ATP-sensitive potassium channel [mito-K (ATP)] in exercise preconditioning of myocardial ischemia-reperfusion injury in rats. Eighty SD rats were randomly divided into high-, moderate-, low-intensity, and control groups. The exercise groups were divided into control and inhibited groups. The control group was divided into model and sham groups. Eight rats were ...
