Mitochondrial potassium and chloride channels.
Channels selective for potassium or chloride ions are present in inner mitochondrial membranes. They probably play an important role in mitochondrial events such as the formation of delta pH and regulation of mitochondrial volume changes. Mitochondrial potassium and chloride channels could also be the targets for pharmacologically active compounds such as potassium channel openers and antidiabe...
متن کاملMitochondrial potassium channels: from pharmacology to function.
Mitochondrial potassium channels, such as ATP-regulated or large conductance Ca2+ -activated and voltage gated channels were implicated in cytoprotective phenomenon in different tissues. Basic effects of these channels activity include changes in mitochondrial matrix volume, mitochondrial respiration and membrane potential, and generation of reactive oxygen species. In this paper, we describe t...
متن کاملMitochondrial potassium ATP channels and retinal ischemic preconditioning.
PURPOSE To examine the mechanisms of ischemic preconditioning (IPC) related to the opening of mitochondrial KATP (mKATP) channels in the retina. METHODS Rats were subjected to retinal ischemia after IPC, or retinas were rendered ischemic after pharmacological opening of mKATP channels. The effects of blocking mKATP channel opening, nitric oxide synthase (NOS) subtypes, or protein kinase C (PK...
متن کاملMitochondrial ATP-dependent potassium channels: novel effectors of cardioprotection?
BACKGROUND Brief interruptions of coronary blood flow paradoxically protect the heart from subsequent prolonged ischemia. The basis of such endogenous cardioprotection, known as "ischemic preconditioning," remains uncertain. Pharmacological evidence has implicated ATP-dependent potassium (KATP) channels in the mechanism of preconditioning; however, the effects of sarcolemmal KATP channels on ex...
متن کاملIsoflurane-induced postconditioning via mitochondrial calcium-activated potassium channels.
PURPOSE Activation of the mitochondrial calcium-activated potassium (mKCa) channel reportedly confers resistance to myocardial ischemic stress. However, the role of the mKCa channel in postconditioning induced by volatile anesthetic remains unclear. METHODS Male Japanese white rabbits underwent coronary artery occlusion for 30 min followed by reperfusion for 3 h. Volatile anesthetic, isoflura...
