  • Title: Reactive oxygen radicals in signaling and damage in the ischemic brain.
    Author: Chan PH.
    Journal: J Cereb Blood Flow Metab; 2001 Jan; 21(1):2-14. PubMed ID: 11149664.
    Abstract:
    Reactive oxygen species have been implicated in brain injury after ischemic stroke. These oxidants can react and damage the cellular macromolecules by virtue of the reactivity that leads to cell injury and necrosis. Oxidants are also mediators in signaling involving mitochondria, DNA repair enzymes, and transcription factors that may lead to apoptosis after cerebral ischemia. Transgenic or knockout mice with cell- or site-specific prooxidant and antioxidant enzymes provide useful tools in dissecting the events involving oxidative stress in signaling and damage in ischemic brain injury.
