Glycolytic metabolites are critical modulators of oocyte maturation and viability. [PDF]

open access: yesPLoS ONE, 2013
The maturation of an oocyte into an egg is a key step in preparation for fertilization. In Xenopus, oocyte maturation is independent of transcription, being regulated at the level of translation and post-translational modifications of proteins.

Effect of estrous cycle stage on oocyte in vitro maturation of domestic cats reared under tropical conditions

open access: yesRevista Científica, 2023
Oocyte maturation is a critical step for in vitro embryo production. In female cats, findings on the influence of the estrous cycle stage on oocyte quality and maturation are contradictory.

In vivo induction of oocyte maturation and ovulation in zebrafish. [PDF]

open access: yesPLoS ONE, 2011
The maturation of fish oocytes is a well-characterized system induced by progestins via non-genomic actions. In a previous study, we demonstrated that diethylstilbestrol (DES), a non-steroidal estrogen, induces fish oocyte maturation via the membrane ...

Twenty-first century oocyte cryopreservation—in vitro maturation of immature oocytes from ovarian tissue cryopreservation in cancer patients: A systematic review

open access: yesWomen's Health, 2022
Objectives: Our review aimed to consolidate the latest update on the application of in vitro maturation among immature oocyte harvest in combination with ovarian tissue cryopreservation known as ovarian tissue oocyte–in vitro maturation.

The role of sonic hedgehog signaling pathway in in vitro oocyte maturation

open access: yesJournal of Animal Reproduction and Biotechnology, 2021
In vitro maturation (IVM) of oocytes is the procedure where the immature oocytes are cultivated in a laboratory until they are mature. Since IVM oocytes generally have low developmental competence as compared to those matured in vivo, development of an ...

Regulated mitochondrial DNA replication during oocyte maturation is essential for successful porcine embryonic development. [PDF]

open access: yes, 2006
Cellular ATP is mainly generated through mitochondrial oxidative phosphorylation, which is dependent on mitochondrial DNA (mtDNA). We have previously demonstrated the importance of oocyte mtDNA for porcine and human fertilization.

Oocyte Maturation and Development [PDF]

open access: yesF1000Research, 2016
Sexual reproduction is essential for many organisms to propagate themselves. It requires the formation of haploid female and male gametes: oocytes and sperms. These specialized cells are generated through meiosis, a particular type of cell division that produces cells with recombined genomes that differ from their parental origin.

METTL3-mediated m6A is required for murine oocyte maturation and maternal-to-zygotic transition

open access: yesCell Cycle, 2020
N6-methyladenosine (m6A) is the most prevalent epigenetic modification of messenger RNA (mRNA) in higher eukaryotes; this modification is mainly catalyzed by a methyltransferase complex including methyltransferase-like 3 (METTL3) as a key factor ...

Involvement of the serine protease inhibitor, SERPINE2, and the urokinase plasminogen activator in cumulus expansion and oocyte maturation. [PDF]

open access: yesPLoS ONE, 2013
The serpin peptidase inhibitor, clade E, member 2 (SERPINE2) inhibits urokinase-type plasminogen activator (PLAU) and tissue-type plasminogen activator.
