这篇讲什么
本文发现线粒体频繁发生可逆的“串珠”现象,该现象通过钙内流触发,并由嵴结构调节,从而驱动线粒体DNA核仁的解聚和规则分布。
原文开头
Pearling drives mitochondrial DNA nucleoid distribution Juan C. Landoni1*, Matthew D. Lycas1, Josefa Macuada1,2, Willi Stepp1, Roméo Jaccard1, Christopher J. Obara3†, Andrew S. Moore3, David Hoffman3, Jennifer Lippincott-Schwartz3, Wallace Marshall4, Gabriel Sturm4, Suliana Manley1* Mitochondria carry their own independently replicating genome, mitochondrial DNA (mtDNA), which is considered a remnant of their endosymbiotic origins (1). In humans, mtDNA encodes 13 core subunits of the oxidative phosphorylation system as well as RNA required for their expression. Consequently, mtDNA integrity and copy number maintenance are critical for mitochondrial function and cellular health, with their disruption leading to a range of metabolic and neurological disorders (2, 3). …
