Distribution of lifetimes of kinetochore-microtubule attachments: interplay of energy landscape, molecular motors and microtubule (de-)polymerization

, 2014
Before a cell divides into two daughter cells, chromosomes are replicated resulting in two sister chromosomes embracing each other. Each sister chromosome is bound to a separate proteinous structure, called kinetochore (kt), that captures the tip of a ...

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.

Mitotic noncoding RNA processing promotes kinetochore and spindle assembly in Xenopus

Journal of Cell Biology, 2016
Grenfell et al. show that transcription and RNA processing occur in metaphase-arrested egg extracts and that noncoding RNA biogenesis is important for centromere, kinetochore, and mitotic spindle assembly.

Phosphatase-regulated recruitment of the spindle- and Kinetochore-Associated (Ska) Complex to kinetochores

Biology Open, 2017
Kinetochores move chromosomes on dynamic spindle microtubules and regulate signaling of the spindle checkpoint. The Spindle and Kinetochore-Associated (Ska) Complex, a hexamer composed of two copies of Ska1, Ska2 and Ska3, has been implicated in both roles.

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

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

BUB-1 promotes amphitelic chromosome biorientation via multiple activities at the kinetochore

eLife, 2018
Accurate chromosome segregation relies on bioriented amphitelic attachments of chromosomes to microtubules of the mitotic spindle, in which sister chromatids are connected to opposite spindle poles.

B cells and systemic sclerosis interstitial lung disease

Arthritis &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 ...

Mitotic spindle: kinetochore fibers hold on tight to interpolar bundles

European Biophysics Journal, 2017
When a cell starts to divide, it forms a spindle, a micro-machine made of microtubules, which separates the duplicated chromosomes. The attachment of microtubules to chromosomes is mediated by kinetochores, protein complexes on the chromosome.

A randomized, placebo‐controlled trial of hydroxychloroquine in incomplete lupus

Arthritis &Rheumatology, Accepted Article.
Objectives Patients with features of systemic lupus erythematosus (SLE) who do not fulfill classification criteria can be designated as incomplete lupus (ILE). This condition includes individuals with a high risk of progression to SLE. Treatment of ILE may reduce symptoms, severity and incidence of SLE. Methods Hydroxychloroquine (HCQ) was chosen as an

When the Clock Is Ticking: The Role of Mitotic Duration in Cell Fate Determination

BioEssays, EarlyView.
Recently, several studies identified mechanisms by which cells measure mitotic duration and how this influences cell fate, leading to normal cell cycle progression or G1 arrest. In light of drug‐resistant cancer cells that continue proliferating even after mitotic errors, understanding these mechanisms opens the door for new potential therapeutic ...
