Anthracyclines are active clinical agents that have multiple mechanisms of cytotoxicity. Cardiotoxicity by anthracyclines limits the therapeutic potential of these agents, but mechanisms leading to cardiotoxicity remain controversial. Transgenic mice that lack mitochondrial topoisomerase I are hypersensitive to doxorubicin cardiotoxicity, providing support for cardiotoxicity arising from damage of mitochondrial DNA.
蒽环类药物是具有多种细胞毒性机制的活性临床药物。蒽环类药物引起的心脏毒性限制了这些药物的治疗潜力,但导致心脏毒性的机制仍存在争议。缺乏线粒体拓扑异构酶I的转基因小鼠对阿霉素心脏毒性高度敏感,这为线粒体DNA损伤引起的心脏毒性提供了支持。
