title: Cardiac reanimation: targeting cardiomyocyte death by BNIP3 and NIX/BNIP3L.
abstract: Programmed cardiac myocyte death contributes to pathological ventricular remodeling and the progression of myocardial infarction or pressure overload hypertrophy to dilated cardiomyopathy. Recent work has identified importance of stress-mediated transcriptional induction of BNIP3 (BCL2 and 19-kDa interacting protein-3) and NIX/BNIP3L in cardiac remodeling. Here, the regulatory mechanisms for these two factors in the heart and their effects on programmed cardiomyocyte death are reviewed, with a focus on information derived from studies using mouse models of cardiac BNIP3 and NIX/BNIP3L overexpression and gene ablation.
