BACKGROUND We recently demonstrated that the sarcolemmal ATP-sensitive potassium (sarcK(ATP)) channel plays a key role in cardioprotection against ischemia/reperfusion injuries in Kir6.2-knockout (KO) mice. In the present study, we evaluated the effects of diazoxide, a mitochondrial ATP-sensitive potassium (mitoK(ATP)) channel opener, on ischemia-induced myocardial stunning in sarcK(ATP) channe...
The goal of this study was to determine whether cigarette smoke extract alters dilatation of arterioles in vivo in response to agonists that produce activation of ATP-sensitive potassium channels and activation of adenylate cyclase. By using intravital microscopy, we measured diameter of arterioles contained within the microcirculation of the hamster cheek pouch during suffusion with agonists i...
Neutrophil activation and migration during an inflammatory response is preceded or accompanied by plasma membrane electrical changes. Besides changes in calcium currents, neutrophils have a high permeability to potassium, mainly through potassium channels. However, the significance of potassium channels in neutrophil physiology is still unclear. Here, we show that the treatment of rats with the...
Opioid type of analgesics open ATP sensitive potassium channel at the cellular level to produce antinociceptive response. These channels have also been shown to modulate insulin secretion by the pancreas. 7-hydroxy flavone, an antinociceptive agent shown to act through opioid pathways was investigated for its effect on glycaemic state and associated algesic state. The involvement of ATP sensiti...
BACKGROUND MCC-134 (1-[4-(H-imidazol-1-yl)benzoyl]-N-methylcyclobutane-carbothioamide), a newly developed analog of aprikalim, opens surface smooth muscle-type ATP-sensitive potassium (K(ATP)) channels but inhibits pancreatic K(ATP) channels. However, the effects of MCC-134 on cardiac surface K(ATP) channels and mitochondrial K(ATP) (mitoK(ATP)) channels are unknown. A mixed agonist/blocker wit...
