Winter hibernation and UCHL1-p34cdc2 association in toad oocyte maturation competence. [PDF]
PLoS ONE, 2013 Currently, it is believed that toad oocyte maturation is dependent on the physiological conditions of winter hibernation. Previous antibody-blocking experiments have demonstrated that toad ubiquitin carboxyl-terminal hydrolase L1 (tUCHL1) is necessary ...

Chromosome transfer in mature oocytes [PDF]
Fertility and Sterility, 2010 In this article, we describe detailed protocols for the isolation and transfer of spindle-chromosomal complexes between mature, metaphase II-arrested oocytes. In brief, the spindle-chromosomal complex is visualized using a polarized microscope and extracted into a membrane-enclosed karyoplast.

Advanced Science, EarlyView.Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Advanced Science, EarlyView.Maternal exercise (ME) increases apelin abundance across maternal and fetal tissues and is associated with improved fetal osteogenesis under POLG mutation‐induced mitochondrial dysfunction. Apelin‐APJ signaling is linked to enhanced mitochondrial function, Akt phosphorylation, and ATF4‐RUNX2 association, supporting coordinated fetal bone remodeling ...

Effects of melatonin on in vitro oocyte maturation and embryo development in pigs [PDF]
Veterinary WorldBackground and Aim: In vitro fertilization (IVF) efficiency in pigs remains suboptimal, partly due to oxidative stress during oocyte maturation and embryo development.

Activation of proteolysis during oocyte in vitro maturation [PDF]
In vitro maturation (IVM) is a form of assisted reproductive technology (ART) applied to obtain mature oocytes in culture. Decline in IVM success rates by age has led consideration of novel approaches based on cellular dynamics.

In-vitro maturation of human oocytes
Reproductive BioMedicine Online, 2004 Immature human oocytes can be matured and fertilized in vitro. However, subsequent embryonic development is different when the immature oocytes are retrieved in different situations. Exposure to the LH surge in vivo may be important for the oocytes to acquire the competence for maturation and subsequent embryonic development.

Does ‘Dual Trigger’ Increase Oocyte Maturation Rate?
, 2020 The aim of this study was to evaluate the oocyte maturation rate when GnRH-a and hCG (dual trigger) are co-administered, compared to the standard hCG trigger within the same patient. Included in the study were GnRH antagonist ICSI cycles performed in 137

Advanced Science, EarlyView.Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...
