Mitochondrial creatine kinase (Mi-CK) occurs in dimeric and octameric forms, both in vitro and in vivo. The Mi-CK octamer, however, is the predominant form in vivo and is important for various functions of the protein. In the present study we show for the first time a significant decrease of the octamer/dimer ratio in vivo, related to ischemia-induced damage, and a similar decrease of octamer stability in vitro, induced by peroxynitrite (PN) radicals. We used animal models to induce ischemia in… CONTINUE READING
