On the possibility of yet a third kinetochore system in the protist phylum Euglenozoa

open access: yesmBio
Transmission of genetic material from one generation to the next is a fundamental feature of all living cells. In eukaryotes, a macromolecular complex called the kinetochore plays crucial roles during chromosome segregation by linking chromosomes to ...

Clinical and molecular features of PRCD‐associated retinopathy

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To describe the clinical and genetic characteristics of patients with biallelic disease‐causing variants in the PRCD (Progressive Rod‐Cone Degeneration) gene. Methods Multicentre, retrospective cohort study of 19 patients from 13 families across nine reference centres in six countries.

Chromosomal and immune dysregulation underlying granular mitosis in glioblastoma

open access: yesBrain Pathology, EarlyView.
Granular mitosis (GM) morphology is linked to PI3K/PTEN pathway alterations, chromosomal disorganization, and impaired innate immunity. Cells exhibiting GM morphology are associated with localized immune responses within their immediate spatial microenvironment.

Immunohistochemistry as a tool for identifying PDGFRA amplification in central nervous system tumors

open access: yesBrain Pathology, EarlyView.
PDGFRA gene amplification is now recognized as a diagnostically and prognostically relevant molecular alteration in central nervous system tumors. Herein, we demonstrated that PDGFRA immunohistochemistry is a highly specific and sensitive biomarker for identifying PDGFRA amplification and should be part of the neuropathologist's routine panel of ...

Keeping kinetochores on track

open access: yesEuropean Journal of Cell Biology, 2012
The multiple functions of kinetochores are reflected in their complex composition, with over a hundred different proteins, which self-associate in several functional subcomplexes. Most of these kinetochore proteins were identified over the last 10-12 years using a combination of genetic, cell biological, biochemical, and bioinformatic approaches in ...

Notoginsenoside‐Fa mitigates vascular endothelial permeability via targeting SUGT1 to stabilize NLRP3 in a resting state

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Notoginsenoside‐Fa (Noto‐Fa) is an emerging active compound derived from notoginseng with promise in treating cardiovascular diseases. The development of cardiovascular diseases is intricately linked to the damage of vascular endothelium and it is widely acknowledged that numerous chronic inflammation pathways, especially the ...

Meiosis-specific distal cohesion site decoupled from the kinetochore

open access: yesNature Communications
Primary constriction of the M-phase chromosome serves as a marker for the kinetochore position. Underlying this observation is the concept that the kinetochore is spatially linked with the pericentromere where sister-chromatids are cohered. Here, we find

Ionizing Radiation and Ultraviolet Light Irradiation‐Associated DNA Damage Increasing Genomic Instability Risk

open access: yesCancer Science, EarlyView.
UV irradiation induces two major types of pyrimidine dimers, CPDs and 6–4PPs. Whereas 6–4PPs efficiently induce cell‐cycle arrest, CPDs do not and frequently persist into S phase. As a result, DSBs can arise in the presence of unrepaired CPDs after 6–4PPs have been repaired, increasing the risk of genomic instability.

Pathogenicity of NUSAP1 Variants Is Defined by NMD‐Escape: Evidence From Two Novel Cases and Systematic Population‐Based Variant Analysis

open access: yesClinical Genetics, EarlyView.
Heterozygous de novo nonsense variants in the penultimate and last exons of NUSAP1 were identified in two unrelated individuals, predicted to escape NMD. In population data, nonsense variants were observed in exons 1–9 (of 11) in NUSAP1 but were absent from its 3′‐terminal region.

Chromosome instability and kinetochore dysfunction [PDF]

open access: yes, 2007
Chromosomal instability (CIN) has been recognized as a hallmark of human cancer and is caused by continuous chromosome missegregation during mitosis.
