Altered status of glutathione and its metabolites in cystinotic cells.
BACKGROUND Cystinosis is an autosomal recessive disorder, caused by mutations of the lysosomal cystine carrier cystinosin, encoded by the CTNS gene (17p13). The concomitant intralysosomal cystine accumulation leads to multi-organ damage, with kidneys being the first affected. Altered mitochondrial oxidative phosphorylation has been demonstrated in animal proximal tubules loaded with cystine dim...
متن کاملPharmacokinetics of Glutathione and Its Metabolites in Normal Subjects
To determine the loading and maintenance dosage of glutathione (GSH) for patients suffering from reactive oxygen species (ROS) injury such as acute paraquat intoxication, a kinetic study of reduced GSH was performed in synchrony with that of cysteine (Cys), cystine (Cys2), and methionine (Met). Human subject's porticipitation was voluntary. The effective dose of Cys, Cys2, and Met against ROS i...
متن کاملInvolvement of different human glutathione transferase isoforms in the glutathione conjugation of reactive metabolites of troglitazone.
Null mutation of glutathione transferase (GST) M1 and GSTT1 was reported to correlate statistically with an abnormal increase in the plasma levels of alanine aminotransferase or aspartate aminotransferase caused by troglitazone in diabetic patients (Clin Pharmacol Ther, 73:435-455, 2003). This clinical evidence leads to the hypothesis that GSH conjugation catalyzed by GSTT1 and GSTM1 has a role...
متن کاملChanges in the pig small intestinal mucosal glutathione kinetics after weaning.
Glutathione (GSH) serves as a major endogenous antioxidant and its kinetics have been poorly described in the weaned pig. This study was to assess the effect of birth weight, sex, and days postweaning on the small intestine (SI) mucosal GSH kinetics. At weaning (18.8 ± 0.44 d) 34 pairs of intrauterine growth restricted (IUGR) and normal birth weight sex-matched littermates were selected and fed...
متن کاملBiliary glutathione promotes the mucosal metabolism of luminal peroxidized lipids by rat small intestine in vivo.
We previously found that exogenous GSH enhances mucosal GSH and promotes lipid hydroperoxide metabolism by rat small intestine (AW, T. Y., and M. W. WIlliams, 1992. Am. J. Physiol. 263:G665-G672). In this study, we have developed an in vivo bile and lymph fistula rat model to test the hypothesis that biliary GSH is an important luminal source of GSH. Peroxidized fish oil was infused into the pr...
