Cardiovascular ATP-sensitive potassium channels
Sulfonylurea drugs stimulate endogenous insulin secretion by blockade of ATP-sensitive potassium channels in pancreatic beta cells. These drugs are widely used in the treatment of type 2 diabetes. However, as ATP-sensitive potassium channels also exist in cardiomyocytes and coronary and peripheral arterial vascular smooth muscle cells, sulfonylurea drug usage in theory may cause unwanted cardio...
متن کاملRecombinant cardiac ATP-sensitive potassium channels and cardioprotection.
The ATP-dependent potassium channels (KATP channels) were originally identified in isolated membrane patches prepared from guinea pig ventricular myocytes by Noma in 1983. Since their discovery in cardiac cells, KATP channels have also been discovered in many other tissues, such as smooth muscle, skeletal muscle, pancreas, and brain, in which they have been shown to couple cellular metabolism t...
متن کاملFunctional roles of cardiac and vascular ATP-sensitive potassium channels clarified by Kir6.2-knockout mice.
-ATP-sensitive potassium (K(ATP)) channels were discovered in ventricular cells, but their roles in the heart remain mysterious. K(ATP) channels have also been found in numerous other tissues, including vascular smooth muscle. Two pore-forming subunits, Kir6.1 and Kir6.2, contribute to the diversity of K(ATP) channels. To determine which subunits are operative in the cardiovascular system and t...
متن کاملAnti-nociceptive effect of cimetidine in mice: the role of ATP-sensitive potassium channels
Recent studies have shown that intracerebroventricular administration of cimetidine (CIM) induces anti-nociceptive and anti–inflammatory effects in rats. However, the underlying mechanism of CIM effect has not been determined yet. This study was planned to determine the anti-nociceptive effect of CIM (50 mg/kg, i.p.) in male mice (25-30 g, n = 80) using tail flick test. Also, the role of ATP-se...
