Correlation Research of Thioredoxin Reductase in Lung Cancer

In pre-clinical study the investigators found that the thioredoxin reductase activity of serum harbours huge difference between cancer patients and non-cancer patients, the enzyme activity elevated remarkably among cancer patients, so the investigators hypothesis that this is due to tumor cells loading of the patients, the enzyme activity may harbours huge difference between carcinoma tissues and para-carcinoma tissues in early staged non-small cell lung cancers, and after surgery, the enzyme activity may fall down to a normal level because of removing of tumor.
