ATP-sensitive potassium channel (KATP channel) expression in the normal canine pancreas and in canine insulinomas
BACKGROUND Pancreatic beta cells express ATP-sensitive potassium (KATP) channels that are needed for normal insulin secretion and are targets for drugs that modulate insulin secretion. The KATP channel is composed of two subunits: a sulfonylurea receptor (SUR 1) and an inward rectifying potassium channel (Kir6.2). KATP channel activity is influenced by the metabolic state of the cell and initia...
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 کاملATP-sensitive potassium (KATP) channel activation decreases intraocular pressure in the anterior chamber of the eye.
PURPOSE. ATP-sensitive potassium channel (K(ATP)) openers target key cellular events, many of which have been implicated in glaucoma. The authors sought to determine whether K(ATP) channel openers influence outflow facility in human anterior segment culture and intraocular pressure (IOP) in vivo. METHODS. Anterior segments from human eyes were placed in perfusion organ culture and treated with ...
متن کاملRegulation of myometrial contraction by ATP-sensitive potassium (KATP) channel via activation of SUR2B and Kir 6.2 in mouse
ATP-sensitive potassium (KATP) channels are well characterized in cardiac, pancreatic and many other muscle cells. In the present study, functional expression of the KATP channel was examined in non-pregnant murine longitudinal myometrium. Isometric contraction measurements and Western blot were used. KATP channel openers (KCOs), such as pinacidil, cromakalim, diazoxide and nicorandil, inhibite...
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...
