[ Summary ] Markers of oxidative stress include anti-oxidants as well as chemical adducts caused by reactive oxygen species (ROS). Thioredoxin, a redox-regulating molecule having -Cys-Gly-Pro-Cys- in its active site, plays an important role in regulating intracellular redox status and signal transduction. The serum or plasma levels of thioredoxin measured with the enzyme-linked immunosorbent assay (ELISA) system are regarded as a good marker of oxidative stress. The level increases in patients with oxidative stress-related diseases, such as viral infection and inflammatory disease. The elevated levels of thioredoxin correlate with the severity and poor prognosis of the diseases. Furthermore, since thioredoxin is a promising target for regulating oxidative stress related diseases, a translational research project administrating recombinant thioredoxin is in progress.
