1 Mammalian thioredoxin reductase (TR) is a flavoprotein catalysing reduction of oxidized thioredoxin in an NADPH-dependent manner, and contains a selenocysteine (Sec) residue near the C-terminus. NADP peroxiredoxin 5 Rattus norvegicus
2 Mammalian thioredoxin reductase (TR) is a flavoprotein catalysing reduction of oxidized thioredoxin in an NADPH-dependent manner, and contains a selenocysteine (Sec) residue near the C-terminus. NADP peroxiredoxin 5 Rattus norvegicus
3 We observed that TR activity was decreased in A549 cells by the lowering of the fetal bovine serum content in the culture medium and was recovered by the addition of selenium. Selenium peroxiredoxin 5 Rattus norvegicus
4 TR activities in COS-1 cells expressing rat TR were increased in accordance with supplemented sodium selenite concentrations, whereas levels of TR protein, examined by Western blotting, were not affected by sodium selenite concentrations. Sodium Selenite peroxiredoxin 5 Rattus norvegicus
5 TR activities in COS-1 cells expressing rat TR were increased in accordance with supplemented sodium selenite concentrations, whereas levels of TR protein, examined by Western blotting, were not affected by sodium selenite concentrations. Sodium Selenite peroxiredoxin 5 Rattus norvegicus
6 These data clearly showed a requirement of selenium for the formation of functional TR protein. Selenium peroxiredoxin 5 Rattus norvegicus
