Webb13 apr. 2024 · The clinical phenotypes of abnormal oocyte cytoplasmic maturation often manifest in different forms, including fertilization failure, zygotic cleavage failure, and early embryonic arrest . Inactivating mutations in WEE2 lead to fertilization failure by disrupting CDC2 phosphorylation, and account for ~40% of cases of fertilization failure resulting … Webb5 aug. 2024 · We also inhibited DRP1 activity to examine its roles in mitochondrial function, reactive oxygen species (ROS) production, and induction of apoptosis during porcine oocyte maturation. Our results provide evidence for the critical roles of DRP1 monitoring oxidative stress and apoptosis in porcine oocytes.
WebbConsequently, the in vitro development of the embryo was protected against the negative effects of ROS. The role of Pannexins in oocyte maturation is crucial but not clearly defined, whereas Connexins have been well studied.
