PLoS Genetics, 2020 The requirements for oocyte meiotic cytokinesis during polar body extrusion are not well understood. In particular, the relationship between the oocyte meiotic spindle and polar body contractile ring dynamics remains largely unknown.

Mechanisms of Meiotic Spindle Initiation in Caenorhabditis elegans Oocytes [PDF]
, 2023 Microtubule-based spindle formation is essential to faithful chromosome segregation during cell division. In many animal species, the oocyte meiotic spindle forms without centrosomes (the major microtubule organizing centers), unlike most mitotic cells ...

Oocyte Meiotic Spindle Assembly and Function
, 2016 Gametogenesis in animal oocytes reduces the diploid genome content of germline precursors to a haploid state in gametes by discarding ¾ of the duplicated chromosomes through a sequence of two meiotic cell divisions called meiosis I and II. The assembly of the microtubule-based spindle structure that mediates this reduction in genome content remains ...

Frontiers in Cell and Developmental Biology, 2021 Mitochondrial division inhibitor 1 (Mdivi-1) reportedly provides a close connection between oocyte maturation and mitochondrial function in pigs. N-acetyl-5-methoxy-tryptamine (melatonin) is known to be a representative antioxidant with the ability to ...

Simulated microgravity compromises mouse oocyte maturation by disrupting meiotic spindle organization and inducing cytoplasmic blebbing. [PDF]
PLoS ONE, 2011 In the present study, we discovered that mouse oocyte maturation was inhibited by simulated microgravity via disturbing spindle organization. We cultured mouse oocytes under microgravity condition simulated by NASA's rotary cell culture system, examined ...

How to halve ploidy : lessons from budding yeast meiosis [PDF]
, 2012 Maintenance of ploidy in sexually reproducing organisms requires a specialized form of cell division called meiosis that generates genetically diverse haploid gametes from diploid germ cells.

Meiotic spindle visualization in living human oocytes
Reproductive BioMedicine Online, 2005 A computer-assisted polarization microscopy system (polscope) has made it possible to analyse the meiotic spindle of oocytes subjected to intracytoplasmic sperm injection (ICSI) without affecting their viability. It has been shown that the presence of a detectable birefringent meiotic spindle inside the oocyte cytoplasm of human metaphase II (MII ...

PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility
Advanced Science, EarlyView.PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.
