Mitochondrial DNA homeostasis in growing cells

Mitochondrial DNA (mtDNA) constitutes a substantial proportion of DNA in eukaryotes, and its regulation is critical not only for mitochondrial function but also for cell survival. However, it is still unclear how mtDNA copy number is maintained during cell proliferation and how mtDNA copy number impacts on cell function. Recently, my group showed that in budding yeast, mtDNA copy number is tightly linked to cell volume to maintain constant concentrations, providing an elegant and potentially conserved strategy for mtDNA homeostasis. But how is mtDNA coupled to cell volume? Based on my group’s work, we proposed that nuclear-encoded mtDNA maintenance factors produced in proportion to cell…
