The Cyclin B2/CDK1 Complex Conservatively Inhibits Separase Activity in Oocyte Meiosis II
Frontiers in Cell and Developmental Biology, 2021 Recently, we have reported that the cyclin B2/CDK1 complex regulates homologous chromosome segregation through inhibiting separase activity in oocyte meiosis I, which further elucidates the compensation of cyclin B2 on cyclin B1’s function in meiosis I ...

MicroRNA Activity Is Suppressed in Mouse Oocytes [PDF]
Current Biology, 2010 MicroRNAs (miRNAs) are small endogenous RNAs that typically imperfectly base pair with 3' untranslated regions (3'UTRs) and mediate translational repression and mRNA degradation. Dicer, which generates small RNAs in the miRNA and RNA interference (RNAi) pathways, is essential for meiotic maturation of mouse oocytes.

Preimplantation Developmental Competence of Bovine and Porcine Oocytes Activated by Zinc Chelation
Animals, 2022 After sperm-oocyte fusion, intracytoplasmic rises of calcium (Ca) induce the release of zinc (Zn) out of the oocyte (Zn sparks). Both phenomena are known to play an essential role in the oocyte activation process.

Regulation of the maternal-to-embryonic transition in "C. elegans" [PDF]
, 2012 Reproduction is a fundamental process of life which allows the survival of each species through the birth of young species members. Several modes of reproduction evolved and are classified into sexual and asexual reproduction.

Maternal effects on oocyte quality in farmed Atlantic halibut (Hippoglossus hippoglossus L.) [PDF]
, 2013 Atlantic halibut (Hippoglossus hippoglossus) oocyte quality is highly variable and one of the major bottlenecks during fry-production for on-growth in commercial Atlantic halibut farming.

A PAR-1-dependent orientation gradient of dynamic microtubules directs posterior cargo transport in the Drosophila oocyte [PDF]
, 2011 Cytoskeletal organization is central to establishing cell polarity in various cellular contexts, including during messenger ribonucleic acid sorting in Drosophila melanogaster oocytes by microtubule (MT)-dependent molecular motors.

Osmolarity-regulated swelling initiates egg activation in Drosophila
Open Biology, 2021 Egg activation is a series of highly coordinated processes that prepare the mature oocyte for embryogenesis. Typically associated with fertilization, egg activation results in many downstream outcomes, including the resumption of the meiotic cell cycle ...

Integrated Environmental Assessment and Management, EarlyView., 2023 Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Pharmaceuticals, 2023 Mammalian oocyte activation is initiated by intracellular calcium (Ca2+) oscillations, driven by the testis-specific phospholipase C zeta (PLCζ). Sperm PLCζ analysis represents a diagnostic measure of sperm fertilisation capacity.
