Overexpression of Bcl-2 attenuates apoptosis and protects against myocardial I/R injury in transgenic mice.
To test whether the antiapoptotic protein Bcl-2 prevents apoptosis and injury of cardiomyocytes after ischemia-reperfusion (I/R), we generated a line of transgenic mice that carried a human Bcl-2… Expand
