Autoantibody response towards chromatin in patients with juvenile idiopathic arthritis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Juvenile idiopathic arthritis (JIA) patients frequently exhibit antinuclear antibodies (ANAs), but the specific antigen target recognized by them and the presence of additional autoantibody specificities in JIA patients remains elusive. Methods Plasma samples from 110 untreated patients with active JIA, as well as from 14 children with ...

Gene replacement strategies validate the use of functional tags on centromeric chromatin and invalidate an essential role for CENP-AK124ub

open access: yesCell Reports, 2021
Summary: Functional tags are ubiquitous in cell biology, and for studies of one chromosomal locus, the centromere, tags have been remarkably useful. The centromere directs chromosome inheritance at cell division. The location of the centromere is defined

Reconstruction of the kinetochore: a prelude to meiosis

open access: yesCell Division, 2007
In eukaryotic organisms, chromosomes are spatially organized within the nucleus. Such nuclear architecture provides a physical framework for the genetic activities of chromosomes, and changes its functional organization as the cell moves through the ...

Differences in IgG Sialylation Distinguish Asymptomatic from Symptomatic Anti‐Nuclear Antibody Positive Individuals

open access: yesArthritis &Rheumatology, Accepted Article.
Objective The transition from asymptomatic anti‐nuclear antibody (ANA) positivity to systemic autoimmune rheumatic disease (SARD) is associated with increased production of pro‐inflamamtory factors such as TNF‐α. Here we investigate whether the relative absence of inflammation in asymptomatic ANA+ individuals (ANA+NS) results from a lack of circulating

B cells and systemic sclerosis interstitial lung disease

open access: yesArthritis &Rheumatology, Accepted Article.
Interstitial lung disease is an important complication of systemic sclerosis (SSc‐ILD) with high mortality and morbidity. Recent clinical studies in SSc‐ILD have led to FDA‐approved therapies in SSc‐ILD. Importantly, evidence from these studies has been extrapolated to guide management of interstitial lung diseases of other systemic autoimmune ...

HO Endonuclease-Initiated Recombination in Yeast Meiosis Fails To Promote Homologous Centromere Pairing and Is Not Constrained To Utilize the Dmc1 Recombinase

open access: yesG3: Genes, Genomes, Genetics, 2018
Crossover recombination during meiosis is accompanied by a dramatic chromosome reorganization. In Saccharomyces cerevisiae, the onset of meiotic recombination by the Spo11 transesterase leads to stable pairwise associations between previously ...

Coordinated gene expression within sustained STAT3‐associated chromatin conformations contributes to hepatocellular carcinoma progression

open access: yesCancer Communications, EarlyView.
Abstract Background Phosphorylated signal transducer and activator of transcription 3 (p‐STAT3) has emerged as a critical modulator of hepatocellular carcinoma (HCC) progression. However, its role in three‐dimensional (3D) chromatin conformation and the expression of genes linked to HCC aggressiveness remains largely unexplored.

Insights into Centromere DNA Bending Revealed by the Cryo-EM Structure of the Core Centromere Binding Factor 3 with Ndc10

open access: yesCell Reports, 2018
Summary: The centromere binding factor 3 (CBF3) complex binds the third centromere DNA element in organisms with point centromeres, such as S. cerevisiae.

The PP2A‐B56 Binding Site LxxIxE Contributes to Asp‐Mediated Spindle Pole Stability

open access: yesCytoskeleton, EarlyView.
ABSTRACT The organization of microtubules into a mitotic spindle is critical for animal cell proliferation and involves the cooperation of hundreds of proteins whose molecular roles and regulation are not fully understood. The protein product of the Drosophila gene abnormal spindle, Asp, is a microtubule‐associated protein required for correct mitotic ...
