While the immediate consequence of amplification of mitochondrial oxidant stress is loss of mitochondrial protein function due to modification of thiols [33], peroxynitrite mediated nitrotyrosine formation [48] and oxidative mitochondrial DNA damage [41], the critical event resulting in escalation of cell wide damage is induction of the mitochondrial permeability transition (MPT)
