ScholarBank@NUS Repository. https://doi.org/10.1089/ars.2007.1865||Abstract:||MitoQ has been developed as a mitochondrial targeted antioxidant for diseases associated with oxidative stress. Here we show that MitoQ blocks the generation of reactive oxygen species (ROS) and mitochondrial protein thiol oxidation, and preserves mitochondrial function and ultrastructure after glutathione (GSH) depletion. Furthermore, the antioxidant effect of MitoQ is conserved in cells lacking mitochondrial DNA, indicating that its antioxidant properties do not depend on a functional electron transport chain (ETC). Our results elucidate the antioxidant mechanism of MitoQ and suggest that it may be a useful therapeutic for disorders associated with a dysfunctional ETC and increased ROS production. © 2008 Mary Ann Liebert, Inc.||Source Title:||Antioxidants and Redox Signaling||URI:||http://scholarbank.nus.edu.sg/handle/10635/107752||ISSN:||15230864||DOI:||10.1089/ars.2007.1865|
