Production of Reactive Oxygen Species by Mitochondria
The mitochondrial respiratory chain is a major source of reactive oxygen species (ROS) under pathological conditions including myocardial ischemia and reperfusion. Limitation of electron transport by the inhibitor rotenone immediately before ischemia decreases the production of ROS in cardiac myocytes and reduces damage to mitochondria. We asked if ROS generation by intact mitochondria during t...

متن کاملCa2+ and reactive oxygen species in staurosporine-induced neuronal apoptosis.
Staurosporine (0.03-0.5 microM) induced a dose-dependent, apoptotic degeneration in cultured rat hippocampal neurons that was sensitive to 24-h pretreatments with the protein synthesis inhibitor cycloheximide (1 microM) or the cell cycle inhibitor mimosine (100 microM). To investigate the role of Ca2+ and reactive oxygen species in staurosporine-induced neuronal apoptosis, we overexpressed calb...
متن کاملMitochondria are a major source of paraquat-induced reactive oxygen species production in the brain.
Paraquat (PQ(2+)) is a prototypic toxin known to exert injurious effects through oxidative stress and bears a structural similarity to the Parkinson disease toxicant, 1-methyl-4-pheynlpyridinium. The cellular sources of PQ(2+)-induced reactive oxygen species (ROS) production, specifically in neuronal tissue, remain to be identified. The goal of this study was to determine the involvement of bra...
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...
