Abstract
Contrary to our hypothesis, impaired mitochondrial respiration could not be explained by intrinsic differences in respiratory complexes reserves among tissues or, by alterations in mitochondrial thresholds after treatment. Instead, we propose that loss of cytochrome c and cardiolipin are responsible for the depressed mitochondrial respiration observed after chronic DOX treatment. Moreover, cardiac cytochrome c and cardiolipin depletion decreases metabolic network buffering, hindering cardiac ability to respond to increased workload, accelerating cardiac aging.
