线粒体是细胞生存所必需的,并且以其在能量产生中的作用而闻名。这些细胞器还参与许多其他对细胞功能至关重要的生物学过程,因此在细胞生死决定中发挥核心作用。在大多数细胞类型中,线粒体形成高度动态的网状网络。维持这些复杂的、不断变化的网络的形状对于线粒体和细胞功能至关重要,并且需要线粒体分裂和融合的保守活动。在过去的二十年里,我们对介导这些动态活动的分子机器的认识取得了巨大的进步。这些进展是由使用高度互补的体外和体内方法驱动的,这些方法已被证明非常强大,可用于研究驱动细胞器裂变和融合的复杂膜重塑过程。在这一章中,我们详细介绍了目前用于研究线粒体分裂和融合在体外和体内的机制和调节的方法。
Mitochondria are required for cell survival and are best known for their role in energy production. These organelles also participate in many other biological processes that are critical for cellular function and, thus, play a central role in cellular life and death decisions. In a majority of cell types, mitochondria form highly dynamic, reticular networks. Maintaining the shape of these complex, ever-changing networks is critical for mitochondrial and cellular function and requires the conserved activities of mitochondrial fission and fusion. Great advances in our knowledge about the molecular machines that mediate these dynamic activities have been made over the past two decades. These advances have been driven by the use of highly complementary in vitro and in vivo approaches that have proven extremely powerful for studying the complex membrane remodeling processes that drive fission and fusion of the organelle. In this chapter, we detail current methods used to examine the mechanisms and regulation of mitochondrial fission and fusion in vitro and in vivo.
