Mitochondria: Biogenesis and mitophagy balance in segregation and clonal expansion of mitochondrial DNA mutations.

Abstract excerpt

Mitochondria are cytoplasmic organelles containing their own multi-copy genome. They are organized in a highly dynamic network, resulting from balance between fission and fusion, which maintains homeostasis of mitochondrial mass through mitochondrial biogenesis and mitophagy. Mitochondrial DNA (mtDNA) mutates much faster than nuclear DNA. In particular, mtDNA point mutations and deletions may occur somatically...
