摘要: 线粒体是一种存在于大多数细胞中具有双层膜结构和流动性的细胞器,是细胞进行有氧呼吸的主要场所,为细胞增殖、迁移和生存提供能量,被称为“能量工厂”。线粒体在细胞死亡、细胞衰老、自噬、脂质合成、钙稳态以及铁平衡等生物过程中均发挥着重要作用,其功能主要由线粒体融合和分裂调节。线粒体融合将有助于ATP的产生,主要由线粒体融合蛋白1(mitofusin-1,Mfn1)、线粒体融合蛋白2(mitofusin-2,Mfn2)以及视神经萎缩蛋白1(optic atrophy 1,OPA1)进行调节;线粒体分裂可促进细胞分裂和有丝分裂,主要由动力相关蛋白1(dynamin-related protein 1,Drp1)、分裂蛋白1(fission 1,Fis1)、线粒体分裂因子(mitochondria fission factor,MFF)以及线粒体动力蛋白49/51(mitochondria dynamin protein 49/51,Mid49/51)进行调节。本文针对线粒体融合和分裂以及氧化磷酸化的分子机制展开讨论,强调线粒体形态和动力学的生物学意义,特别是相关基因和蛋白在动物机体和细胞中的调节机制,并对线粒体动力学和形态学在畜牧学中的研究趋势进行展望,以期为今后线粒体的研究提供参考。

Abstract: Mitochondria is an organelle with double layered membrane and fluidity, which is the main place for aerobic respiration of cells and provides energy for cell proliferation, migration and survival, hence it is called “power house”. Mitochondria plays an important role in biological processes such as cell death, cell senescence, autophagy, lipid synthesis, calcium homeostasis and iron balance, etc, and its function is mainly regulated by mitochondrial fusion and fission. ATP production is regulated by mitochondrial fusion related proteins such as mitofusin-1 (Mfn1), mitofusin-2 (Mfn2) and optic atrophy 1 (OPA1). Cell division and mitosis are promoted by mitochondria fission related proteins such as dynamin-related protein 1 (Drp1), fission 1 (Fis1), mitochondria fission factor (MFF) and mitochondria dynamin protein 49/51 (Mid49/51). This review discusses the molecular mechanisms of mitochondrial fusion, fission and oxidative phosphorylation, emphasizes the biological significance of mitochondrial morphology and dynamics, especially the regulation mechanism of mitochondria related genes and proteins in bodys and cells of animals, and prospects the research trends of mitochondrial dynamics and morphology in animal husbandry, which will provides a reference for mitochondrial research.

Key words: mitochondria, fusion, fission, oxidative phosphorylation
