Differences in Dynamics of Specific Antinuclear Antibodies and Their Susceptibility to B Cell–Targeting Treatment in Patients With Systemic Lupus Erythematosus

Arthritis &Rheumatology, EarlyView.
Objective The presence of antinuclear antibodies (ANAs) is characteristic for systemic lupus erythematosus (SLE). Antibody dynamics over time are thought to reflect the cellular source of ANAs and their therapeutic targetability. Anti–double‐stranded DNA (anti‐dsDNA) is the most prevalent and well‐studied of all ANAs, and fluctuations in anti‐dsDNA ...

Massively multiplex single-molecule oligonucleosome footprinting

eLife, 2020
Our understanding of the beads-on-a-string arrangement of nucleosomes has been built largely on high-resolution sequence-agnostic imaging methods and sequence-resolved bulk biochemical techniques. To bridge the divide between these approaches, we present

Structural basis for retroviral integration into nucleosomes

Nature, 2015
Retroviral integration is catalysed by a tetramer of integrase (IN) assembled on viral DNA ends in a stable complex, known as the intasome. How the intasome interfaces with chromosomal DNA, which exists in the form of nucleosomal arrays, is currently ...

Antiphospholipid Syndrome: An Antibody‐Mediated Disease With Emerging Therapeutic Opportunities

Arthritis &Rheumatology, EarlyView.
Antiphospholipid syndrome (APS) is an autoimmune thromboinflammatory disease characterized by vascular thrombosis, pregnancy morbidity, and other manifestations driven by antiphospholipid autoantibodies. In this review, we present a clinical case that illustrates some diagnostic and therapeutic challenges in managing severe, relapsing APS ...

CENP-A nucleosomes localize to transcription factor hotspots and subtelomeric sites in human cancer cells

Epigenetics & Chromatin, 2015
BackgroundThe histone H3 variant CENP-A is normally tightly regulated to ensure only one centromere exists per chromosome. Native CENP-A is often found overexpressed in human cancer cells and a range of human tumors. Consequently, CENP-A misregulation is

Autoantibody response towards chromatin in patients with juvenile idiopathic arthritis

Arthritis &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 ...

Asymmetric nucleosomes flank promoters in the budding yeast genome

Genome Research, 2015
Nucleosomes in active chromatin are dynamic, but whether they have distinct structural conformations is unknown. To identify nucleosomes with alternative structures genome-wide, we used H4S47C-anchored cleavage mapping, which revealed that 5% of budding ...

The size of the nucleosome

, 2011
The structural origin of the size of the 11 nm nucleosomal disc is addressed. On the nanometer length-scale the organization of DNA as chromatin in the chromosomes involves a coiling of DNA around the histone core of the nucleosome. We suggest that the size of the nucleosome core particle is dictated by the fulfillment of two criteria: One is ...

Alu Overexpression Leads to an Increased Double‐stranded RNA Signature in Dermatomyositis

Arthritis &Rheumatology, Accepted Article.
Objective Dermatomyositis is an autoimmune condition characterized by a high interferon signature of unknown etiology. Because coding sequences constitute <1.2% of our genomes, there is a need to explore the role of the non‐coding genome in disease pathogenesis.

Circulating nucleosomes as epigenetic biomarkers in pancreatic cancer

Clinical Epigenetics, 2015
BackgroundTo improve the prognosis of patients with pancreatic cancer, new biomarkers are required for earlier, pre-symptomatic diagnosis. Epigenetic mutations take place at the earliest stages of tumorigenesis and therefore offer new approaches for ...
