Mitochondrial glutathione transport is a key determinant of neuronal susceptibility to oxidative and nitrosative stress.
Mitochondrial oxidative stress significantly contributes to the underlying pathology of several devastating neurodegenerative disorders. Mitochondria are highly sensitive to the damaging effects of reactive oxygen and nitrogen species; therefore, these organelles are equipped with a number of free radical scavenging systems. In particular, the mitochondrial glutathione (GSH) pool is a critical ...
متن کاملDysregulation of Glutathione Homeostasis in Neurodegenerative Diseases
Dysregulation of glutathione homeostasis and alterations in glutathione-dependent enzyme activities are increasingly implicated in the induction and progression of neurodegenerative diseases, including Alzheimer's, Parkinson's and Huntington's diseases, amyotrophic lateral sclerosis, and Friedreich's ataxia. In this review background is provided on the steady-state synthesis, regulation, and tr...
متن کاملEfficacy: A Review Glutathione Metabolism as a Determinant of Therapeutic
Glutathione, as the chief nonprotein intracellular sulfhydryl, affects the efficacy and interactions of a variety of antineoplastic interventions, mainly through nucleophilic thioether formation or oxidation-reduction reactions. Thus, glutathione plays a role in the detoxification and repair of cellular injury by such diverse agents as mechlorethamine, melphalan, cyclophosphamide, nitrosoureas,...

متن کاملMitochondrial glutathione, a key survival antioxidant.
Mitochondria are the primary intracellular site of oxygen consumption and the major source of reactive oxygen species (ROS), most of them originating from the mitochondrial respiratory chain. Among the arsenal of antioxidants and detoxifying enzymes existing in mitochondria, mitochondrial glutathione (mGSH) emerges as the main line of defense for the maintenance of the appropriate mitochondrial...
