Abstract:
Oxidative stress has been implicated in brain injury after ischemia, which is a complex cascade. These oxidants produced by oxidative stress are directly involved in oxidative damage with cellular macromolecules such as lipids, proteins and nucleic acids, which lead to cell death. Oxidants are also mediators in signaling involving mitochondria pathway, DNA repair enzymes, and transcription factor that may lead to apoptosis after cerebral ischemia. Antioxidangt enzymes (such as superoxide dismutase,etc) provide useful tools in dissecting the events involving oxidative stress in signaling and damage in ischemic brain injury. This review focuses on the mechanisms of oxidative stress during brain ischemia.
