Novel nucleotide-binding sites in ATP-sensitive potassium channels formed at gating interfaces.

The coupling of cell metabolism to membrane electrical activity is a vital process that regulates insulin secretion, cardiac and neuronal excitability and the responses of cells to ischemia. ATP-sensitive potassium channels (K(ATP); Kir6.x) are a major part of this metabolic-electrical coupling system and translate metabolic signals such as the ATP:ADP ratio to changes in the open or closed sta...

Mechanosensitive gating of atrial ATP-sensitive potassium channels.

Cell-attached and inside-out excised-patch recording techniques were used to search for mechanosensitive ion channels in neonatal and adult rat atrial myocytes. A channel activated by negative pressure applied to the patch, with a single-channel conductance of 52 pS in symmetric potassium solutions, was frequently observed. This channel has been identified as the atrial ATP-sensitive potassium ...

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...

Anti-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...
