Targeting Hexokinase II to mitochondria to modulate energy metabolism and reduce ischemia‐reperfusion injury in heart
Summary Mitochondrially‐bound hexokinase II (mtHKII) has long been known to confer cancer cells with their resilience against cell death. More recently, mtHKII has emerged as a powerful protector against cardiac cell death. mtHKII protects against IR injury in skeletal muscle and heart, attenuates cardiac hypertrophy and remodelling, and is one of the major end‐effectors through which ischemic preconditioning protects against myocardial ischemia‐reperfusion injury. Mechanisms of mtHKII cardioprotection against reperfusion injury entail the maintenance of regulated OMM permeability during ischemia and reperfusion resu...

Mitochondrial metals as a potential therapeutic target in neurodegeneration
Summary Transition metals are critical for enzyme function and protein folding, but in excess can mediate neurotoxic oxidative processes. As mitochondria are particularly vulnerable to oxidative damage due to radicals generated during ATP production, mitochondrial biometal homeostasis must therefore be tightly controlled to safely harness the redox potential of metal enzyme cofactors. Dysregulation of metal functions is evident in numerous neurological disorders including Alzheimer's disease, stroke, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis and Friedrich's Ataxia. This review describes the m...
