The microtubule cross-linker Feo controls the midzone stability, motor composition, and elongation of the anaphase B spindle in Drosophila embryos. [PDF]

, 2015
Chromosome segregation during anaphase depends on chromosome-to-pole motility and pole-to-pole separation. We propose that in Drosophila embryos, the latter process (anaphase B) depends on a persistent kinesin-5-generated interpolar (ip) microtubule (MT)

Chromosome segregation in lymphocyte hybrids [PDF]

Hereditas, 2009
Chromosome segregation was studied in mouse/human and mouse/mouse T-lymphocyte hybrids, and in mouse/human, mouse/rabbit and mouse/rat B-lymphocyte hybrids. Chromosome loss was not random, it was moderate in mouse/mouse and mouse/rat lymphocyte hybrids, but extensive in mouse/human and mouse/rabbit lymphocyte hybrids.

BMI‐1 modulation and trafficking during M phase in diffuse intrinsic pontine glioma

FEBS Open Bio, EarlyView.
The schematic illustrates BMI‐1 phosphorylation during M phase, which triggers its translocation from the nucleus to the cytoplasm. In cycling cells, BMI‐1 functions within the PRC1 complex to mediate H2A K119 monoubiquitination. Following PTC596‐induced M phase arrest, phosphorylated BMI‐1 dissociates from PRC1 and is exported to the cytoplasm via its

The dynamics of signal amplification by macromolecular assemblies for the control of chromosome segregation [PDF]

, 2016
The control of chromosome segregation relies on the spindle assembly checkpoint (SAC), a complex regulatory system that ensures the high fidelity of chromosome segregation in higher organisms by delaying the onset of anaphase until each chromosome is ...

Bacterial Chromosome Organization and Segregation [PDF]

Cold Spring Harbor Perspectives in Biology, 2010
Bacterial chromosomes are generally approximately 1000 times longer than the cells in which they reside, and concurrent replication, segregation, and transcription/translation of this crowded mass of DNA poses a challenging organizational problem. Recent advances in cell-imaging technology with subdiffraction resolution have revealed that the bacterial

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

FEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Bactofilin-mediated organization of the ParABS chromosome segregation system in Myxococcus xanthus

Nature Communications, 2017
In bacteria, homologs of actin, tubulin, and intermediate filament proteins often act in concert with bacteria-specific scaffolding proteins to ensure the proper arrangement of cellular components. Among the bacteria-specific factors are the bactofilins,

Autosomal Recessive Spastic Ataxia of Charlevoix‐Saguenay in Two Half‐Siblings

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Autosomal recessive spastic ataxia of Charlevoix‐Saguenay (ARSACS) is caused by biallelic pathogenic variants in the SACS gene. We report the clinical, radiologic and neurophysiologic features of a pair of half‐siblings who presented with progressive cerebellar ataxia, peripheral neuropathy and upper motor neuron signs.

Unique Function of the Bacterial Chromosome Segregation Machinery in Apically Growing Streptomyces - Targeting the Chromosome to New Hyphal Tubes and its Anchorage at the Tips.

PLoS Genetics, 2016
The coordination of chromosome segregation with cell growth is fundamental to the proliferation of any organism. In most unicellular bacteria, chromosome segregation is strictly coordinated with cell division and involves ParA that moves the ParB ...

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

Advanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.
