TGFβ1 protects myocardium from apoptosis and oxidative damage after ischemia reperfusion.

Myocardial apoptosis is an important pathologic basis of ischemia-reperfusion injury (I/R). Transforming growth factor β1 (TGFβ1) participates in the regulation of oxidative damage and apoptosis. TGFβ1 is upregulated in the repair process of I/R injury. It is speculated that TGFβ1 over-expression is involved in the endogenous protective mechanism of I/R injury. This study explores the significance of TGFβ1 in myocardial cell apoptosis after...
