title: Molecular biology of doxorubicin-induced cardiomyopathy.
abstract: The anthracycline doxorubicin is an antineoplastic agent, eliciting chronic cardiac toxicity. It occurs in patients after prolonged administration of doxorubicin, leading to congestive heart failure. The pathogenesis of the doxorubicin-induced car-diomyopathy is not well understood. The present article summarizes the unique effect of doxorubicin on cardiac-specific gene expression. In addition to binding to DNA, doxorubicin directly affects the function of a variety of proteins. Free radical generation, damage to mitochondria and active cell death are also critical in the development of doxorubicin-induced cardiac toxicity. Agents providing effective cardioprotection are also reviewed.
