The Role of Mitochondria in Oocyte Maturation [PDF]
Cells, 2021 With the nucleus as an exception, mitochondria are the only animal cell organelles containing their own genetic information, called mitochondrial DNA (mtDNA). During oocyte maturation, the mtDNA copy number dramatically increases and the distribution of mitochondria changes significantly.

Profiles and roles of N6-methyladenosine modification in bovine oocyte maturation [PDF]
BMC GenomicsBackground Bovine oocyte quality is crucial for successful in vitro embryo production; therefore, elucidating the mechanisms underlying oocyte maturation is essential.

Cells, 2020 Oocyte maturation is a process that occurs in the ovaries, where an immature oocyte resumes meiosis to attain competence for normal fertilization after ovulation/spawning. In starfish, the hormone 1-methyladenine binds to an unidentified receptor on the plasma membrane of oocytes, inducing a conformational change in the heterotrimeric GTP-binding ...

Induction and inhibition of oocyte maturation by EDCs in zebrafish [PDF]
Reproductive Biology and Endocrinology, 2005 Background Oocyte maturation in lower vertebrates is triggered by maturation-inducing hormone (MIH), which acts on unidentified receptors on the oocyte surface and induces the activation of maturation-promoting factor (MPF) in the oocyte cytoplasm.

Loss of DLGAP5 impairs human and mouse oocyte maturation via disrupting the PI3K-AKT signaling axis [PDF]
Journal of Ovarian ResearchBackground At present, the known genetic causes of abnormal oocyte development can only account for a minority of female infertility. In our previous study, the mutation c.1101 C > G, p.Tyr367* in discs large-associated protein 5 (DLGAP5) was identified ...

Lipid Metabolic Process Involved in Oocyte Maturation During Folliculogenesis
Frontiers in Cell and Developmental Biology, 2022 Oocyte maturation is a complex and dynamic process regulated by the coordination of ovarian cells and numerous extraovarian signals. From mammal studies, it is learnt that lipid metabolism provides sufficient energy for morphological and cellular events ...

Twelve Hours Post-Injection Serum Human Chorionic Gonadotropin and Body Mass Index Predicts In Vitro Fertilization Oocyte Maturation Rate: A Cross-Sectional Study [PDF]
International Journal of Fertility and Sterility, 2023 Background: In vitro fertilization (IVF) remains a main treatment for infertility cases. Post-injection human chorionic gonadotropin(hCG) level is an essential factor in determining oocyte maturation rate in IVF.

Human Reproduction, 1998 Primary oocytes recovered from small and growing follicles of > or = 3 mm in the ovaries of untreated women, can be matured in vitro, will fertilize and develop in vitro, and when transferred to the patient, develop to term. However, the implantation rate of cleaved embryos has been disappointingly low and when embryos are allowed to develop beyond the
