Ischemic A/D transition of mitochondrial complex I and its role in ROS generation

Mitochondrial complex I (NADH:ubiquinone oxidoreductase) is a key enzyme in cellular energy metabolism and provides approximately 40% of the proton-motive force that is utilized during mitochondrial ATP production. The dysregulation of complex I function--either genetically, pharmacologically, or metabolically induced--has severe pathophysiological consequences that often involve an imbalance in the production of reactive oxygen species (ROS)....
