Abstract: Infarction damage is ameliorated or treated through the administration of a mitochondrial degradation inhibitor, such as one that acts by inhibiting translocation of one or more molecules across a mitochondrial membrane, for example BAX/BNIP3 complexes involved in mitochondrial degradation. By preventing mitochondrial degradation, one allows more efficient oxygenation of an infarcted region, allowing for a greater degree of cell survival and a more successful recovery.

Abstract: The invention provides peptides capable of inhibiting the individual activity and inter-pathway communication of BNIP3, BAX and mitochondria. The peptides can be used in methods of treating a disease or condition in a subject in which it is desirable to prevent cell damage and cell death.
