The perpetual movements of anaphase [PDF]
Cellular 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]
Current 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.

Spatiotemporal control of mitotic exit during anaphase by an aurora B-Cdk1 crosstalk
eLife, 2019 According to the prevailing ‘clock’ model, chromosome decondensation and nuclear envelope reformation when cells exit mitosis are byproducts of Cdk1 inactivation at the metaphase-anaphase transition, controlled by the spindle assembly checkpoint. However,

Cell Reports, 2017 The onset of anaphase is triggered by activation of the anaphase-promoting complex/cyclosome (APC/C) following silencing of the spindle assembly checkpoint (SAC).

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

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.

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 ...

Proceedings 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.

A Regulatory Switch Alters Chromosome Motions at the Metaphase-to-Anaphase Transition
Cell Reports, 2016 To achieve chromosome segregation during mitosis, sister chromatids must undergo a dramatic change in their behavior to switch from balanced oscillations at the metaphase plate to directed poleward motion during anaphase.

Keeping Order in Anaphase [PDF]
Developmental 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.
