Anaphase B [PDF]

open access: yesBiology, 2016
Anaphase B spindle elongation is characterized by the sliding apart of overlapping antiparallel interpolar (ip) microtubules (MTs) as the two opposite spindle poles separate, pulling along disjoined sister chromatids, thereby contributing to chromosome ...

Bypassing anaphase by fission yeast cut9 mutation: requirement of cut9+ to initiate anaphase. [PDF]

open access: bronzeThe Journal of cell biology, 1994
A novel anaphase block phenotype was found in fission yeast temperature-sensitive cut9 mutants. Cells enter mitosis with chromosome condensation and short spindle formation, then block anaphase, but continue to progress into postanaphase events such as degradation of the spindle, reformation of the postanaphase cytoplasmic microtubule arrays, septation,

Anaphase in vitro. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1996
Despite their varied appearances, all mitotic spindles have a similar architecture: they are organized as two half spindles, and the microtubules in each half spindle are of the same polarity, with many of the plus ends of the microtubules that grow out from the poles interacting with chromosomes or the microtubules of the other half spindle.

The perpetual movements of anaphase [PDF]

open access: yesCellular and Molecular Life Sciences, 2010
One of the most extraordinary events in the lifetime of a cell is the coordinated separation of sister chromatids during cell division. This is truly the essence of the entire mitotic process and the reason for the most profound morphological changes in cytoskeleton and nuclear organization that a cell may ever experience.

Anaphase B Precedes Anaphase A in the Mouse Egg [PDF]

open access: yesCurrent Biology, 2012
Segregation of chromosomes at the time of cell division is achieved by the microtubules and associated molecules of the spindle. Chromosomes attach to kinetochore microtubules (kMTs), which extend from the spindle pole region to kinetochores assembled upon centromeric DNA.

Keeping Order in Anaphase [PDF]

open access: yesDevelopmental Cell, 2015
The critical components of chromosome segregation machinery are well established, but how they orchestrate the relative order of events during mitosis remains unclear. Kamenz et al. (2015) now report in Molecular Cell quantitative data suggesting competing networks and adaptive thresholds in the control of mitotic exit by the anaphase-promoting complex.

APC/C-Cdh1-targeted substrates as potential therapies for Alzheimer’s disease

open access: yesFrontiers in Pharmacology, 2022
Alzheimer’s disease (AD) is the most prevalent neurodegenerative disorder and the main cause of dementia in the elderly. The disease has a high impact on individuals and their families and represents a growing public health and socio-economic burden ...

Testing of mitosis and meiosis in female and male gametes

open access: yesАндрология 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 ...

Anaphase Promoting Complex or Cyclosome? [PDF]

open access: yesCell Cycle, 2005
The anaphase promoting complex/cyclosome (APC/C) was initially described as a multi-subunit protein complex that ubiquitinates anaphase inhibitors thus targeting them for destruction by proteasomes to initiate loss of sister chromatid cohesion. However, recent studies have identified important new functions of the APC/C.

Cohesin is dispensable for centromere cohesion in human cells. [PDF]

open access: yesPLoS ONE, 2007
Proper regulation of the cohesion at the centromeres of human chromosomes is essential for accurate genome transmission. Exactly how cohesion is maintained and is then dissolved in anaphase is not understood.We have investigated the role of the cohesin ...
