A serious consequence of ischemia-reperfusion injury (I/R) is oxidative damage leading to mitochondrial dysfunction. Such I/R-induced mitochondrial dysfunction is observed as impaired state 3 respiration and overproduction of O2(-). The cascading ROS…
SOD2 is the primary antioxidant enzyme neutralizing (*)O2(-) in mitochondria. Cardiac-specific SOD2 overexpression (SOD2-tg) induces supernormal function and cardiac hypertrophy in the mouse heart. However, the reductive stress imposed by SOD2…
Complex I is a critical site of O(2)(*-) production and the major host of reactive protein thiols in mitochondria. In response to oxidative stress, complex I protein thiols at the 51- and 75-kDa subunits are reversibly
