摘要: 目的 分析PDK4调控内质网-线粒体接触位点(Mitochondria-Associated Membranes, MAMs)即“内质网-线粒体对话”的分子机制,并探讨其与蒽环类药物心脏毒性的潜在关联,为研发心脏保护策略提供理论依据。方法 通过对近年来相关文献的检索和分析,系统综述了PDK4在MAMs中的作用机制,及其在蒽环类药物心脏毒性中的作用。结果 研究发现,PDK4、MAMs及蒽环类药物心脏毒性之间存在复杂的相互作用,主要体现在能量代谢障碍、氧化应激、细胞凋亡和钙稳态失衡等方面,这些相互作用在蒽环类药物心脏毒性的发展过程中发挥重要作用。结论 PDK4通过过表达,主要破坏MAMs介导的钙稳态,造成线粒体钙超载,进而影响蒽环类药物心脏毒性,这为开发针对蒽环类药物心脏毒性的保护策略提供思路和潜在靶点。

Abstract: Objective To analyze the molecular mechanism through which PDK4 regulates Mitochondria-Associated Membranes(MAMs) and explore its potential association with anthracycline-induced cardiotoxicity in order to provide data for developing cardioprotective strategies. Methods By reviewing recent literature, the role of PDK4 in MAMs and its potential involvement in anthracycline-induced cardiotoxicity was explored. Results There were complicated interactions between PDK4, MAMs, and anthracycline-induced cardiotoxicity, primarily manifested as energy metabolism disorders, oxidative stress, apoptosis, and calcium homeostasis imbalance. These interactions played a significant role in the progression of anthracycline-induced cardiotoxicity. Conclusion Overexpression of PDK4 can, above all, disrupt calcium homeostasis mediated by MAMs, leading to mitochondrial calcium overload and consequently exacerbating anthracycline-induced cardiotoxicity. This study can offer novel insights and help identify potential therapeutic targets for developing protective strategies against anthracycline-associated cardiotoxicity.
