Mammalian kinetochores count attached microtubules in a sensitive and switch-like manner. [PDF]

, 2019
The spindle assembly checkpoint (SAC) prevents anaphase until all kinetochores attach to the spindle. Each mammalian kinetochore binds many microtubules, but how many attached microtubules are required to turn off the checkpoint, and how the kinetochore ...

Forces on chromosomal DNA during anaphase

Biophysical Journal, 1996
In the course of anaphase, the chromosomal DNA is submitted to the traction of the spindle. Several physical problems are associated with this action. In particular, the sister chromatids are generally topologically intertwined at the onset of anaphase, and the removal of the intertwinings results from a coupling between the enzymatic action of type II

Drug Discovery Applications of Nitroso (Hetero)Arene Derivatives

ChemPlusChem, EarlyView.
Nitroso (hetero)aromatic compounds are bioactive molecules with antiviral, anticancer, neuroprotective, and antimicrobial properties. This review highlights their mechanisms of action—oxidative stress, DNA damage, and enzyme inhibition—alongside synthesis, structure–activity relationships, and toxicity challenges, offering insight into their ...

Blocking microtubule deacetylation inhibits anaphase chromosome movements in crane-fly spermatocytes.

PLoS ONE
Chromosome movement speeds during anaphase are regulated by depolymerization of microtubules. Several models describe chromosome movement during cell division but none of them consider post-translational modifications of tubulin, even though such ...

Critical Evaluation of Methods for the Identification of Aneugens

Environmental and Molecular Mutagenesis, EarlyView.
ABSTRACT The genotoxic potential of chemicals must be evaluated in regulatory safety assessment settings, including but not limited to, the development of new pharmaceuticals, industrial chemicals, food and cosmetic ingredients, and agrochemicals. Initial assessment of the chromosome‐damaging potential of chemicals is often conducted in mammalian cells

Exotic mitotic mechanisms [PDF]

, 2012
The emergence of eukaryotes around two billion years ago provided new challenges for the chromosome segregation machineries: the physical separation of multiple large and linear chromosomes from the microtubule-organizing centres by the nuclear envelope.

Target Binding of Black Phosphorus Nanomaterial to Polo‐Like Kinase 1 for Cancer Chemotherapy: A Mutual Selection of Nanomaterial and Protein

Exploration, EarlyView.
This study investigates the effect of protein properties on the nanomaterial‐protein interaction and elucidates the molecular mechanisms underlying the targeted inhibition of polo‐like kinase (PLK1) by black phosphorus nanomaterials (BPNMs). The specific targeting inhibition is attributed to the intrinsic properties of both the PLK1 protein and the ...

Sequestration of CDH1 by MAD2L2 prevents premature APC/C activation prior to anaphase onset

Journal of Cell Biology, 2013
MAD2L2 is rapidly degraded by APC/CCDC20 at the onset of anaphase, allowing release of sequestered CDH1 to activate the dephosphorylated APC/C.

Epigenomics‐guided precision oncology: Chromatin variants in prostate tumor evolution

International Journal of Cancer, EarlyView.
Abstract Prostate cancer is a common malignancy that in 5%–30% leads to treatment‐resistant and highly aggressive disease. Metastasis‐potential and treatment‐resistance is thought to rely on increased plasticity of the cancer cells—a mechanism whereby cancer cells alter their identity to adapt to changing environments or therapeutic pressures to create
