Abstract excerpt

The quality of mitochondria inherited from the oocyte determines embryonic viability, lifelong metabolic health of the progeny and lineage endurance. High levels of endogenous reactive oxygen species and exogenous toxicants pose threats to mitochondrial DNA (mtDNA) in fully developed oocytes. Deleterious mtDNA is commonly detected in mature oocytes, but is absent in embryos, suggesting the existence of a cryptic...
