Quantitative proteomics reveals the dynamics of protein changes during Drosophila oocyte maturation and the oocyte-to-embryo transition [PDF]
, 2014 The onset of development is marked by two major, posttranscriptionally controlled, events: oocyte maturation (release of the prophase I primary arrest) and egg activation (release from the secondary meiotic arrest).

Diethylstilbestrol induces fish oocyte maturation [PDF]
Proceedings of the National Academy of Sciences, 2004 An endocrine-disrupting chemical, diethylstilbestrol (DES), a nonsteroidal estrogen, triggers oocyte maturation in fish. The morphology (the time course of the change in germinal vesicle breakdown) and an intracellular molecular event (the de novo synthesis of cyclin B) induced by DES were indistinguishable from ...

Coordination of Ovulation and Oocyte Maturation: A Good Egg at the Right Time.
Endocrinology, 2018 Ovulation is the appropriately timed release of a mature, developmentally competent oocyte from the ovary into the oviduct, where fertilization occurs. Importantly, ovulation is tightly linked with oocyte maturation, demonstrating the interdependency of ...

In vitro production of bovine embryos derived from individual donors in the Corral® dish [PDF]
, 2017 Background: Since the identity of the embryo is of outmost importance during commercial in vitro embryo production, bovine oocytes and embryos have to be cultured strictly per donor.

Role of AMPK Throughout Meiotic Maturation in the Mouse Oocyte: Evidence for Promotion of Polar Body Formation and Suppression of Premature Activation [PDF]
, 2010 This study was conducted to assess the role of AMPK in regulating meiosis in mouse oocytes from the germinal vesicle stage to metaphase II. Exposure of mouse cumulus cell-enclosed oocytes (CEO) and denuded oocytes (DO) during spontaneous maturation in ...

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 ...

NAT10 Maintains OGA mRNA Stability Through ac4C Modification in Regulating Oocyte Maturation
Frontiers in Endocrinology, 2022 In vitro maturation (IVM) refers to the process of developing immature oocytes into the mature in vitro under the microenvironment analogous to follicle fluid.

LSD1 is essential for oocyte meiotic progression by regulating CDC25B expression in mice [PDF]
, 2015 Mammalian oocytes are arrested at prophase I until puberty when hormonal signals induce the resumption of meiosis I and progression to meiosis II.

In Vitro maturation of oocytes [PDF]
British Medical Bulletin, 2000 Only about 400 of the one million oocytes present at birth will be ovulated, while the rest will die by atresia. The ability to rescue oocytes destined to die and mature them in vitro would provide invaluable information about folliculogenesis and oocyte maturation, and could provide oocytes for infertile women. In vitro maturation (IVM) is challenging

Maturation arrest of human oocytes at germinal vesicle stage
Journal of Human Reproductive Sciences, 2010 Maturation arrest of human oocytes may occur at various stages of the cell cycle. A total failure of human oocytes to complete meiosis is rarely observed during assisted conception cycles. We describe here a case of infertile couples for whom all oocytes
