Glutathione regulates susceptibility to oxidant-induced mitochondrial DNA damage in human lymphocytes

Oxidative damage to mitochondrial DNA (mtDNA) interferes with the expression of mitochondrial-encoded subunits of the electron transport complexes of oxidative phosphorylation. MtDNA is protected by several mitochondrial antioxidant systems, but…
