Trx and myocardial injury in diabetes

        【Abstract】  Thioredoxin (Trx), as a class of highly conservative protein of low molecular weight, has various biological functions including the promotion of cell growth, anti-free radical, and anti-apoptosis. Trx plays crucial roles in keeping stable redox status and regulating signal transduction of cell. Many studies have shown that Trx involved in the development of myocardial injury in diabetes. Here we will summarize the research progress on the effect of Trx on myocardial injury in patients with diabetes.
