蒽环类药物如阿霉素(Dox)是有效的化疗药物,但其使用受到心脏毒性的限制。我们假设,乳腺癌妇女的血浆蛋白质组学可以确定蒽环类药物心脏毒性的新机制。我们测量了蒽环类药物治疗患者(n = 30)中1317种蛋白质的变化,并在第二个队列(n = 31)中复制了关键发现。在蒽环类药物治疗开始后3个月,血红素结合蛋白(Hpx)的增加与超声心动图显示的心脏毒性相关。为了评估Hpx的功能作用,我们将Hpx给予用Dox治疗的野生型(WT)小鼠,并观察到心脏功能改善。相反,与WT小鼠相比,Hpx−/−小鼠表现出增加的Dox心脏毒性。初步机制研究表明,Hpx可能通过循环单核细胞/巨噬细胞转运到心脏,Hpx可能减轻Dox诱导的铁凋亡,从而提供心脏保护。总之,这些观察结果表明,Hpx诱导代表Dox治疗期间的代偿反应。多柔比星治疗过程中的血红素结合蛋白诱导产生了蒽环类药物心脏毒性的潜在治疗策略。
Anthracyclines such as doxorubicin (Dox) are effective chemotherapies, but their use is limited by cardiac toxicity. We hypothesized that plasma proteomics in women with breast cancer could identify new mechanisms of anthracycline cardiac toxicity. We measured changes in 1317 proteins in anthracycline-treated patients (n = 30) and replicated key findings in a second cohort (n = 31). An increase in the heme-binding protein hemopexin (Hpx) 3 months after anthracycline initiation was associated with cardiac toxicity by echocardiography. To assess the functional role of Hpx, we administered Hpx to wild-type (WT) mice treated with Dox and observed improved cardiac function. Conversely, Hpx−/− mice demonstrated increased Dox cardiac toxicity compared to WT mice. Initial mechanistic studies indicate that Hpx is likely transported to the heart by circulating monocytes/macrophages and that Hpx may mitigate Dox-induced ferroptosis to confer cardioprotection. Together, these observations suggest that Hpx induction represents a compensatory response during Dox treatment. Hemopexin induction during doxorubicin treatment yields a potential therapeutic strategy for anthracycline cardiac toxicity.
