Reactive oxygen species originating from mitochondria regulate the cardiac sodium channel.
RATIONALE Pyridine nucleotides regulate the cardiac Na(+) current (I(Na)) through generation of reactive oxygen species (ROS). OBJECTIVE We investigated the source of ROS induced by elevated NADH. METHODS AND RESULTS In human embryonic kidney (HEK) cells stably expressing the cardiac Na(+) channel, the decrease of I(Na) (52±9%; P<0.01) induced by cytosolic NADH application (100 μmol/L) was ...
متن کاملCardiac mitochondria and reactive oxygen species generation.
Mitochondrial reactive oxygen species (ROS) have emerged as an important mechanism of disease and redox signaling in the cardiovascular system. Under basal or pathological conditions, electron leakage for ROS production is primarily mediated by the electron transport chain and the proton motive force consisting of a membrane potential (ΔΨ) and a proton gradient (ΔpH). Several factors controllin...

متن کاملHypoxic-Ischemic Injury in the Developing Brain: The Role of Reactive Oxygen Species Originating in Mitochondria
Mitochondrial dysfunction is the most fundamental mechanism of cell damage in cerebral hypoxia-ischemia and reperfusion. Mitochondrial respiratory chain (MRC) is increasingly recognized as a source for reactive oxygen species (ROS) in the postischemic tissue. Potentially, ROS originating in MRC can contribute to the reperfusion-driven oxidative stress, promoting mitochondrial membrane permeabil...
متن کاملBrief Review Mitochondria and Reactive Oxygen Species
Fascination by the mitochondria, “the colonial posterity of migrant prokaryocytes, probably primitive bacteria that swam into ancestral precursors of our eukaryotic cells and stayed there,”1 stems from the above-mentioned nebulous endosymbiotic theory of their origin, as well as from the growing realization of a very special role that they play in the pathogenesis of diverse diseases. These org...
