Glutathione levels in male Slc3a1^−/− mice at 8 weeks of age. Reduced (GSH) and oxidized (GSSG) glutathione levels were measured in the livers of wild-type and Slc3a1^−/− animals. GSH, GSSG, total and the ratio of reduced to oxidized forms (GSH:GSSG) were all lowered in Slc3a1^−/− mice (N = 6 ± SEM)
