| Research Abstract |
Human thioredoxin (TRX) has a potent thiol reducing activity and plays an important role on the redox regulation. Yodoi and the the members of the international cooperation program of the redox regulation and cellular signal transduction demonstrated the following results : 1) the targeted disruption of the TRX was embryonic lethal, suggesting the essential role of TRX in the mouse embryogenesis and differentiation. 2) the oxidative responsive element in the thioredoxin promoter was identified. 3) TRX and Ref-1 which is important for the activation of the AP-1 was demonstrated to be able to interact physically. 4) the redox regulation was shown to be important for the binding of transcription factors including steroid hormone receptor or PEBP2.5) the thioredoxin-dependent peroxidase (peroxiredoxin) was characterized and indicated to be involved in scavenging reactive oxygen intermediates. 6) Several groups started to analyze the redox sensor mechanism against oxidative stress. 7) Irreversible oxidative stress was indicated to be involved in several disease processes including iron induced carcinogenesis. Analysis of the signal transduction system and redox regulation seems to be an approach to elucidated the pathogenesis of several diseases. In summary, this international program showed the importance of the further study of the molecular mechanism of the redox regulation and the cellular signal transduction system.
