Nature Communications, 2017 A key feature of meiosis is the step-wise removal of cohesin, the protein complex holding sister chromatids together, first from arms in meiosis I and then from the centromere region in meiosis II.

Genome-wide high-resolution mapping of UV-induced mitotic recombination events in Saccharomyces cerevisiae. [PDF]
, 2013 In the yeast Saccharomyces cerevisiae and most other eukaryotes, mitotic recombination is important for the repair of double-stranded DNA breaks (DSBs). Mitotic recombination between homologous chromosomes can result in loss of heterozygosity (LOH).

Arthritis &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 ...

α satellite DNA variation and function of the human centromere
The Nucleus, 2017 Genomic variation is a source of functional diversity that is typically studied in genic and non-coding regulatory regions. However, the extent of variation within noncoding portions of the human genome, particularly highly repetitive regions, and the ...

Mechanism of 2n gametes formation and centromere mapping in citrus : S02O03 [PDF]
, 2012 Citrus triploid hybrids can be recovered by 2x X 2x hybridisations as a consequence of 2n gamete formation. Two main meiotic processes are at the origin of such gametes, the first division restitution (FDR) and the second division restitution (SDR ...

Autoantibody Response Toward Chromatin in Patients With Juvenile Idiopathic Arthritis
Arthritis &Rheumatology, EarlyView.Objective Patients with juvenile idiopathic arthritis (JIA) frequently exhibit antinuclear antibodies (ANAs), but the specific antigen target recognized by them and the presence of additional autoantibody specificities in patients with JIA remains elusive.

Genome Biology, 2017 BackgroundParadoxically, centromeres are known both for their characteristic repeat sequences (satellite DNA) and for being epigenetically defined. Maize (Zea mays mays) is an attractive model for studying centromere positioning because many of its large

Exceptional aggressiveness of cerebral cavernous malformation disease associated with PDCD10 mutations. [PDF]
, 2015 PurposeThe phenotypic manifestations of cerebral cavernous malformation disease caused by rare PDCD10 mutations have not been systematically examined, and a mechanistic link to Rho kinase-mediated hyperpermeability, a potential therapeutic target, has ...

Arthritis &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
