Abstract: In human atrial trabeculae, we examined the effects of doxorubicin on the isometric force of contraction, mitochondrial respiration, membrane potential and calcium retention capacity. Compared with untreated controls, doxorubicin induced contractile dysfunction and depression of mitochondrial respiration. Mitochondria isolated from doxorubicin-treated human atrial trabeculae displayed reduced transmembrane potential and calcium retention capacity. Cyclosporine A, a mitochondrial membrane transition pore opening blocker, prevented mitochondrial dysfunction and impaired contractile performance induced by doxorubicin. The study suggests that a mitochondrial membrane transition pore opening is involved in the development of doxorubicin cardiotoxicity in human hearts.
