Case Series of Nizon‐Isidor Syndrome by Heterozygous Variants in MED12L With Further Evidence of Mitotic Instability in One Case With Diploid–Triploid Mosaicism

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nizon‐Isidor syndrome is a rare disorder caused by heterozygous variants in MED12L, with only eight documented cases in the literature. Here, we present three additional cases of this syndrome. Proband 1 was a 7‐year‐old female who presented with developmental delay, right‐leg hemihypertrophy, laryngeal cleft, esotropia, abnormal skin ...

Aurora-B kinase pathway controls the lateral to end-on conversion of kinetochore-microtubule attachments in human cells

open access: yesNature Communications, 2017
Human chromosomes are captured along microtubule walls (lateral attachment) and then tethered to microtubule-ends (end-on attachment) through a multi-step end-on conversion process. Upstream regulators that orchestrate this remarkable change in the plane

DSK1, a novel kinesin-related protein from the diatom Cylindrotheca fusiformis that is involved in anaphase spindle elongation. [PDF]

open access: yes, 1996
We have identified an 80-kD protein that is involved in mitotic spindle elongation in the diatom Cylindrotheca fusiformis. DSK1 (Diatom Spindle Kinesin 1) was isolated using a peptide antibody raised against a conserved region in the motor domain of the ...

Non‐Invasive Prenatal Testing by Cell‐Free DNA (cfNIPT) for Detecting Turner Syndrome With Mosaicism and Structural Variants—Prenatal Findings and Postnatal Outcomes

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Turner Syndrome (TS) is a sex chromosomal disorder associated with karyotype heterogeneity. Although TS can be associated with severe prenatal findings, most often linked to the 45, X karyotype, the majority of TS fetuses have no overt phenotype, resulting in delayed diagnosis and management.

Kinetochore alignment within the metaphase plate is regulated by centromere stiffness and microtubule depolymerases [PDF]

open access: yes, 2010
During mitosis in most eukaryotic cells, chromosomes align and form a metaphase plate halfway between the spindle poles, about which they exhibit oscillatory movement. These movements are accompanied by changes in the distance between sister kinetochores,

Comparative analysis of short‐term and long‐term LL‐37‐induced rosacea‐like mouse models: Histopathological features and inflammatory immune responses

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The aim of this study was to improve the long‐term LL‐37 mouse model and compare the disease manifestations and pathophysiology of short‐term and long‐term LL‐37‐induced rosacea‐like models. The results show that the long‐term LL‐37 induced mouse model provides a practical animal model for further study of the pathological mechanism of severe rosacea ...

Anaphase Chromosomes in Crane-Fly Spermatocytes Treated With Taxol (Paclitaxel) Accelerate When Their Kinetochore Microtubules Are Cut: Evidence for Spindle Matrix Involvement With Spindle Forces

open access: yesFrontiers in Cell and Developmental Biology, 2018
Various experiments have indicated that anaphase chromosomes continue to move after their kinetochore microtubules are severed. The chromosomes move poleward at an accelerated rate after the microtubules are cut but they slow down 1–3 min later and move ...

How the kinetochore couples microtubule force and centromere stretch to move chromosomes

open access: yesNature Cell Biology, 2016
The Ndc80 complex (Ndc80, Nuf2, Spc24 and Spc25) is a highly conserved kinetochore protein essential for end-on anchorage to spindle microtubule plus ends and for force generation coupled to plus-end polymerization and depolymerization.

Hand Swelling and Other Non–Raynaud Phenomenon Symptoms as the Initial Presentation of Systemic Sclerosis: Prevalence and Clinical Associations in Two US Cohorts

open access: yesArthritis &Rheumatology, EarlyView.
Objective Raynaud phenomenon (RP) is often the initial clinical manifestation of systemic sclerosis (SSc), but some patients develop other manifestations first. To help elucidate the diversity of SSc presentation in its early stages, we describe the initial clinical manifestations and antinuclear antibody (ANA) profiles of patients in two early SSc ...

PRC1‐labeled microtubule bundles and kinetochore pairs show one‐to‐one association in metaphase

open access: yesEMBO Reports, 2016
In the mitotic spindle, kinetochore microtubules form k‐fibers, whereas overlap or interpolar microtubules form antiparallel arrays containing the cross‐linker protein regulator of cytokinesis 1 (PRC1).
