The effect of calcium on mitochondrial contact sites: a study on isolated rat hearts.


Mitochondrial contact sites are dynamic structures created by fusion of the inner and outer mitochondrial membranes. Stimulation of the metabolism results in an increase of the number of contact sites. Functionally, it is shown that mitochondrial creatine kinase (Mi-CK) is active in contact sites and therefore, Mi-CK cytochemistry was performed (using a… (More)
