摘要
Thioredoxin 1 (Trx1) is a key redox control system within the nucleus, yet little is known about the sensitivity of nuclear Trx1 to oxidative stress. The present study compared oxidant-induced changes in the redox states of nuclear Trx1, cytoplasmic Trx1, and cellular glutathione (GSH). Nuclear Trx1 was more reducing than cytoplasmic Trx1 and cellular GSH in proliferating cells. tert-Butylhydroperoxide caused an increase in the total amount of nuclear Trx1, but this was accompanied by a 60 mV oxidation. Thus, the increase in nuclear Trx1 levels did not correspond to an increase in the overall reducing capacity of Trx1 in the nucleus. (C) 2003 Federation of European Biochemical Societies.
