阿霉素是最重要的抗癌化疗药物之一,广泛应用于实体瘤和急性白血病的治疗。在过去的几十年里,阿霉素和其他蒽环类药物的作用已经得到了深入的研究,但提出的细胞杀伤机制仍然是不同的和有争议的。在这篇综述中,我们从染色质景观的角度研究了阿霉素作用的拟议模型,染色质景观在许多类型的癌症中由于染色质修饰剂的复发突变而改变。我们强调了最近关于蒽环类药物对DNA扭转和染色质动力学的影响的证据,这可能是阿霉素介导的细胞死亡的基本机制的基础,并提出了新的癌症治疗策略。
Doxorubicin is one of the most important anti-cancer chemotherapeutic drugs, being widely used for the treatment of solid tumors and acute leukemias. The action of doxorubicin and other anthracycline drugs has been intensively investigated during the last several decades, but the mechanisms that have been proposed for cell killing remain disparate and controversial. In this review, we examine the proposed models for doxorubicin action from the perspective of the chromatin landscape, which is altered in many types of cancer due to recurrent mutations in chromatin modifiers. We highlight recent evidence for effects of anthracyclines on DNA torsion and chromatin dynamics that may underlie basic mechanisms of doxorubicin-mediated cell death and suggest new therapeutic strategies for cancer treatment.
