Anti-centromere antibody positivity with coexisting idiopathic portal hypertension and primary biliary cholangitis progressing to limited cutaneous systemic sclerosis: a case report

Journal of Medical Case Reports
Background Anti-centromere antibodies are autoantibodies that selectively bind to the centromere region of chromosomes. Studies have indicated that anti-centromere antibodies can induce microvascular alterations and tissue remodeling, ultimately leading ...

A time out for CENP-A

Molecular & Cellular Oncology, 2017
Proper chromosome segregation relies on a functional centromere–kinetochore interface. We showed that chromatin containing CENtromere Protein A (CENP-A) is essential for centromere assembly, but dispensable for chromosome segregation in the presence of ...

CENP-A Ubiquitylation Is Inherited through Dimerization between Cell Divisions

Cell Reports, 2016
The presence of chromatin containing the histone H3 variant CENP-A dictates the location of the centromere in a DNA sequence-independent manner. But the mechanism by which centromere inheritance occurs is largely unknown. We previously reported that CENP-

Centromere deletion in Cryptococcus deuterogattii leads to neocentromere formation and chromosome fusions

eLife, 2020
The human fungal pathogen Cryptococcus deuterogattii is RNAi-deficient and lacks active transposons in its genome. C. deuterogattii has regional centromeres that contain only transposon relics.

Centromere-associated molecular events contribute to species diversification in fungal pathogens.

(a–e) Various molecular events involving centromeres leading to species diversification are depicted, with examples found among the fungal pathogens. (f) An evolutionary model for chromosomal fusion and centromere inactivation in the Malassezia species ...

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

The budding yeast Centromere DNA Element II wraps a stable Cse4 hemisome in either orientation in vivo

eLife, 2014
In budding yeast, a single cenH3 (Cse4) nucleosome occupies the ∼120-bp functional centromere, however conflicting structural models for the particle have been proposed. To resolve this controversy, we have applied H4S47C-anchored cleavage mapping, which

Determining the cellular mechanism of de novo centromere establishment in C. elegans embryos

, 2016
De novo centromere formed rapidly on artificial chromosomes (ACs) after injecting DNA in C. elegans germline. The mechanisms underlining nucleation of a de novo centromere from naked DNA is not known.

Duplication of centromeric histone H3 (HTR12) gene in Arabidopsis halleri and A-lyrata, plant species with multiple centromeric satellite sequences [PDF]

, 2006
Arabidopsis halleri and lyrata have three different major centromeric satellite sequences, a unique finding for a diploid Arabidopsis species. Since centromeric histones coevolve with centromeric satellites, these proteins would be predicted to show ...

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 ...
