| Outline of Final Research Achievements |
The aim of this study is to evaluate the clinical significance of the cellular redox system consisting of thioredoxin and thioredoxin interacting protein (Txnip) for the protection against inflammatory disorders including septi shock, ALI, and ARDS. Since inflammation has been associated with hypoxia and the resulting dysregulation of oxygen homeostasis, we investigated the functional interaction between the thioredoxin system and hypoxia-inducible factor 1 (HIF-1) under inflammatory conditions. We showed that thioredoxin enhanced the transcriptional activity of HIF-1. Thioredoxin-induced HIF-1 activation up-regulated the expression level of Txnip, which could, in turn, suppress the function of thioredoxin. These results revealed that the cellular redox environment was maintained by a subtle balance and interplay between these redox-related molecules.
