HIM-10 is required for kinetochore structure and function on Caenorhabditis elegans holocentric chromosomes. [PDF]

, 2001
Macromolecular structures called kinetochores attach and move chromosomes within the spindle during chromosome segregation. Using electron microscopy, we identified a structure on the holocentric mitotic and meiotic chromosomes of Caenorhabditis elegans ...

Testing of mitosis and meiosis in female and male gametes

Андрология и генитальная хирургия, 2017
Method of quantitative evaluation of the immature germ cells, their pathology in mitosis and meiosis (in semen, embryo and fetal ovaries, of gonad biopsies or fragments of sectioned material) is informative method and should be introduced into the ...

Male meiotic spindle features that efficiently segregate paired and lagging chromosomes

eLife, 2020
Chromosome segregation during male meiosis is tailored to rapidly generate multitudes of sperm. Little is known about mechanisms that efficiently partition chromosomes to produce sperm.

Formation of the postmitotic nuclear envelope from extended ER cisternae precedes nuclear pore assembly [PDF]

, 2011
During mitosis, the nuclear envelope merges with the endoplasmic reticulum (ER), and nuclear pore complexes are disassembled. In a current model for reassembly after mitosis, the nuclear envelope forms by a reshaping of ER tubules.

Central-spindle microtubules are strongly coupled to chromosomes during both anaphase A and anaphase B

bioRxiv, 2019
Spindle microtubules, whose dynamics vary over time and at different locations, cooperatively drive chromosome segregation. Measurements of microtubule dynamics and spindle ultrastructure can provide insight into the behaviors of microtubules, helping ...

SUMO targets the APC/C to regulate transition from metaphase to anaphase

Nature Communications, 2018
Signal transduction by small ubiquitin-like modifier (SUMO) regulates a myriad of nuclear processes. Here we report on the role of SUMO in mitosis in human cell lines. Knocking down the SUMO conjugation machinery results in a delay in mitosis and defects

Cdk1 phosphorylation of Esp1/Separase functions with PP2A and Slk19 to regulate pericentric Cohesin and anaphase onset. [PDF]

PLoS Genetics, 2018
Anaphase onset is an irreversible cell cycle transition that is triggered by the activation of the protease Separase. Separase cleaves the Mcd1 (also known as Scc1) subunit of Cohesin, a complex of proteins that physically links sister chromatids ...

Securin Is Not Required for Chromosomal Stability in Human Cells [PDF]

, 2005
Abnormalities of chromosome number are frequently observed in cancers. The mechanisms regulating chromosome segregation in human cells are therefore of great interest.

A permeabilized cell model for studying cell division: a comparison of anaphase chromosome movement and cleavage furrow constriction in lysed PtK1 cells. [PDF]

, 1981
After lysis in a Brij 58-polyethylene glycol medium, PtK1 cells are permeable to small molecules, such as erythrosin B, and to proteins, such as rhodamine-labeled FAB, myosin subfragment-1, and tubulin.

Pathogenic mutations in the chromokinesin KIF22 disrupt anaphase chromosome segregation

eLife, 2022
The chromokinesin KIF22 generates forces that contribute to mitotic chromosome congression and alignment. Mutations in the α2 helix of the motor domain of KIF22 have been identified in patients with abnormal skeletal development, and we report the ...
