摘要: 线粒体融合、分裂及二者之间的动态转换,统称为线粒体动力学。线粒体融合-分裂参与线粒体的多种生物学功能,包括能量代谢、活性氧、Ca2+稳态和细胞死亡过程的调节等。心脏发育、心肌能量代谢及心肌细胞内离子稳态等与线粒体融合-分裂平衡密切相关,其失衡能引起心肌细胞功能紊乱,导致心肌细胞受损甚至死亡,最终发生心力衰竭。药物靶向重建线粒体融合-分裂平衡可能为慢性心力衰竭的治疗提供新的思路和策略。

Abstract: Mitochondrial fusion、fission and dynamic transformation between the two are commonly known as mitochondrial dynamics. Mitochondrial fusion-fission is related to a variety of biological functions of mitochondria, including regulation of energy metabolism, production of reactive oxygen species, m aintenance of Ca2+ homeostasis and influence of cellular death.It is reported that cardiac development、energy metabolism and ion homeostasis are closely related to the balance of mitochondrial fusion-fission.Mitochondrial fusion-fission disorders could cause myocardial cell dysfunction、damage and even the death of myocardial cells, which result in heart failure ultimately. Developing drugs aiming to reconstruct the balance of mitochondrial fusion-fission may provide new ideas and strategies for the treatment of chronic heart failure.
