Initial treatment strategies and outcomes across haemodynamic thresholds and risk stratification in incident systemic sclerosis–associated pulmonary arterial hypertension: a EUSTAR analysis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Real‐world initial treatment strategies in SSc‐PAH remain incompletely described. We aimed to characterise these strategies across haemodynamic thresholds and risk strata and evaluate outcome associations. Methods We analysed treatment‐naïve SSc‐PAH patients in EUSTAR (2000–2021) fulfilling the 2022 haemodynamic definition.

The cellular mechanisms and consequences of centromere drive

open access: yesCurrent Opinion in Cell Biology, 2018
During female meiosis, only one of four meiotic products is retained in the egg. It was previously proposed that chromosomes might compete for inclusion in the egg via their centromere ‘strength’.

Model selection for the telomere/centromere effect (n = 37 species with a centromere position, 425 chromosomes).

open access: yes, 2022
Three competing models were compared based on the adjusted R2, p-value and AIC-BIC criteria among chromosomes (the best supported model is in bold characters).

Sema4A neutralization reduces fibrosis and inflammation in a mouse model of systemic sclerosis and a 3D model of immunity‐driven fibrosis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective We previously showed that Semaphorin4A (Sema4A) is elevated in patients with systemic sclerosis (SSc) and promotes inflammation and fibrosis in vitro. Here, we examined the effect of Sema4A neutralization in vivo and in 3D fibrosis models. Methods Sema4A plasma levels were measured by ELISA in healthy controls (n=31) and patients with SSc (n=

Centromere mechanical maturation during mammalian cell mitosis

open access: yesNature Communications, 2019
During mitosis, tension at the centromere occurs from the spindle but the role of centromere mechanics in controlling metaphase tension is poorly understood.

Replication Fork Stability Is Essential for the Maintenance of Centromere Integrity in the Absence of Heterochromatin

open access: yesCell Reports, 2013
The centromere of many eukaryotes contains highly repetitive sequences marked by methylation of histone H3K9 by Clr4KMT1. This recruits multiple heterochromatin proteins, including Swi6 and Chp1, to form a rigid centromere and ensure accurate chromosome ...

Structure and Stability of Telocentric Chromosomes in Wheat. [PDF]

open access: yesPLoS ONE, 2015
In most eukaryotes, centromeres assemble at a single location per chromosome. Naturally occurring telocentric chromosomes (telosomes) with a terminal centromere are rare but do exist.

Centromere Chromatin Dynamics at a Glance

open access: yes, 2022
The centromere is a specialized DNA locus that ensures the faithful segregation of chromosomes during cell division. It does so by directing the assembly of an essential proteinaceous structure called the kinetochore. The centromere identity is primarily

Recombinant Monoclonal Antibodies for Detecting the Tubulin Post‐Translational Modifications Glutamylation and Lysine‐40 Acetylation

open access: yesCytoskeleton, EarlyView.
ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

Sister centromere fusion during meiosis I depends on maintaining cohesins and destabilizing microtubule attachments.

open access: yesPLoS Genetics, 2019
Sister centromere fusion is a process unique to meiosis that promotes co-orientation of the sister kinetochores, ensuring they attach to microtubules from the same pole during metaphase I.
