Mouse mitochondria oocyte

Nettet15. jul. 2024 · Mitochondria are mobilized to varying degrees in response to intracellular energy requirements. In mouse oocytes, ATP increases rapidly in GVBD, decreases sharply after 1 h, and then increases slowly, which results in different ATP fluctuations during oocyte maturation [14,15]. Nettet4. apr. 2024 · Maternal mitochondria are the sole source of mtDNA for every cell of the offspring. Heteroplasmic mtDNA mutations inherited from the oocyte are a common cause of metabolic diseases and associated with late-onset diseases. However, the origin and dynamics of mtDNA heteroplasmy remain unclear.
