Bax ablation protects against hepatic ischemia/reperfusion injury in transgenic mice.

Apoptosis appears to be a central mechanism of cell death following reperfusion of the ischemic liver. The aim of this study was to determine the effect of decreased expression of the proapoptotic Bax gene on hepatic apoptotic warm ischemia/reperfusion (I/R) injury. Three groups of mice were studied: homozygotic knockout mice (Bax-/-); heterozygotic (Bax+/-); and wild type (Bax+/+).
