Insights from the reconstitution of the divergent outer kinetochore of Drosophila melanogaster [PDF]

, 2016
Accurate chromosome segregation during mitosis and meiosis is crucial for cellular and organismal viability. Kinetochores connect chromosomes with spindle microtubules and are essential for chromosome segregation.

Microtubule Destabilizing Kinesins: A Historical Perspective and Thoughts for the Future

Cytoskeleton, EarlyView.
ABSTRACT The microtubule cytoskeleton plays critical roles in multiple cellular processes such as mitotic spindle assembly and chromosome segregation. Cells contain a number of microtubule‐associated proteins that regulate microtubule dynamics both temporally and spatially in cells. The microtubule depolymerizing kinesins include members of the Kinesin‐

Initial Characterization of two novel spindle proteins, CHICA and HURP [PDF]

, 2008
During mitotic spindle assembly, the sister chromatids have to be captured by kinetochore (K) -fibers (bundles of kinetochore microtubules; KMTs) to ensure stable attachment of the chromosomes.

High incidence of Y‐chromosome mosaicism in male and female individuals with mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy

Epilepsia, EarlyView.
Abstract Objective Mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE) is an underrecognized pediatric cortical lesion associated with somatic X‐linked SLC35A2 variants in approximately 50% of individuals. The genetic etiology in individuals without detectable SLC35A2 mutations remains undefined, which limits

MET Expression in Upper Gastrointestinal Adenocarcinoma: Prevalence, Prognostic Impact, and Implications for Anti‐MET Antibody‐Drug Conjugate Therapy

International Journal of Cancer, EarlyView.
ABSTRACT MET is an actionable receptor tyrosine kinase, and MET‐directed antibody–drug conjugates (ADCs) have recently entered clinical practice with FDA approval in non‐small cell lung cancer and are now being evaluated across gastrointestinal malignancies, with patient selection based on MET immunohistochemistry (IHC) 3+ membranous staining at ...

BUB-1 promotes amphitelic chromosome biorientation via multiple activities at the kinetochore

eLife, 2018
Accurate chromosome segregation relies on bioriented amphitelic attachments of chromosomes to microtubules of the mitotic spindle, in which sister chromatids are connected to opposite spindle poles.

Polymorphic STRs represent unique genetic signals beyond SNPs associated with climate adaptation in Marchantia polymorpha

iMetaOmics, EarlyView.
Natural populations of Marchantia polymorpha sampled across contrasting climatic regions show clear geographic differentiation between Europe and Japan based on polymorphic short tandem repeat (STR) variation. Genome‐wide association (GWAS) analyses identified pSTR loci whose repeat‐length variation tracks temperature‐related WorldClim variables.

Astrin-SKAP complex reconstitution reveals its kinetochore interaction with microtubule-bound Ndc80

eLife, 2017
Chromosome segregation requires robust interactions between the macromolecular kinetochore structure and dynamic microtubule polymers. A key outstanding question is how kinetochore-microtubule attachments are modulated to ensure that bi-oriented ...

Routine MDM2 FISH Testing and Preoperative Biopsy Reduces Recurrence Rate of Atypical Lipomatous Tumours

Journal of Surgical Oncology, EarlyView.
ABSTRACT Background Although MDM2 FISH test has been increasingly used to differentiate ALT and benign lipomatous tumours, its impact on clinical outcome remains underexplored. This study investigated whether routine MDM2 FISH testing on preoperative biopsy is associated with a reduction in the recurrence risk of ALT.

The dynamic kinetochore-microtubule interface [PDF]

, 2004
The kinetochore is a control module that both powers and regulates chromosome segregation in mitosis and meiosis. The kinetochore-microtubule interface is remarkably fluid, with the microtubules growing and shrinking at their point of attachment to ...
