Bub1 is a fission yeast kinetochore scaffold protein, and is sufficient to recruit other spindle checkpoint proteins to ectopic sites on chromosomes [PDF]
, 2007 The spindle checkpoint delays anaphase onset until all chromosomes have attached in a bi-polar manner to the mitotic spindle. Mad and Bub proteins are recruited to unattached kinetochores, and generate diffusible anaphase inhibitors.

Importin α and vNEBD Control Meiotic Spindle Disassembly in Fission Yeast
Cell Reports, 2018 Summary: In metazoans, the nuclear envelope (NE) breakdown (NEBD) occurs during “open” mitosis and meiosis. In the fission yeast Schizosaccharomyces pombe, the mitosis and the first meiotic division (MI) are “closed,” during which the NE is maintained ...

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.

Disrupted meiotic spindle configurations.
, 2013 Note: Meiotic spindle configurations were evaluated by immunofluorescence analysis of individual oocytes that were fixed at the end of an 18-hour culture. Spindle microtubules were detected with anti-Ac-tubulin, and the DNA was labeled with DAPI.

Cytoplasmic determination of meiotic spindle size revealed by a unique inter-species germinal vesicle transfer model [PDF]
, 2016 Spindle sizes are different in diverse species and cell types. In frogs, the meiotic spindle size is positively correlated with the egg cell volume. Across species, relatively small mouse oocytes (70–80 μm) have a relatively large spindle while larger ...

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 ...

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 ...
