Dynamic epigenetic states of maize centromeres

open access: yesFrontiers in Plant Science, 2015
The centromere is a specialized chromosomal region identified as the major constriction, upon which the kinetochore complex is formed, ensuring accurate chromosome orientation and segregation during cell division.

Stretching the rules: monocentric chromosomes with multiple centromere domains. [PDF]

open access: yesPLoS Genetics, 2012
The centromere is a functional chromosome domain that is essential for faithful chromosome segregation during cell division and that can be reliably identified by the presence of the centromere-specific histone H3 variant CenH3.

Linear assembly of a human centromere on the Y chromosome

open access: yesNature Biotechnology, 2018
The human genome reference sequence remains incomplete owing to the challenge of assembling long tracts of near-identical tandem repeats in centromeres.

Evaluation of sweating responses in patients with systemic connective tissue disorders using the quantitative sudomotor axon reflex test

open access: yesJournal of Cutaneous Immunology and Allergy, Volume 5, Issue 6, Page 208-216, December 2022., 2022
We investigated 85 patients on the relationship between the axon reflex sweat volume or the reaction time and Raynaud's phenomenon, skin symptoms and patient background. Most patients did not show a decrease in sweating, but one in three patients showed less sweating in summer than in winter.

Temporal characterization of homology-independent centromere coupling in meiotic prophase. [PDF]

open access: yesPLoS ONE, 2010
Over the past thirty years several reports of the pairing or association of non-homologous centromeres during meiotic prophase have appeared in the literature.

Recent insights into mechanisms preventing ectopic centromere formation

open access: yesOpen Biology, 2021
The centromere is a specialized chromosomal structure essential for chromosome segregation. Centromere dysfunction leads to chromosome segregation errors and genome instability.

Centromere Repeats: Hidden Gems of the Genome

open access: yesGenes, 2019
Satellite DNAs are now regarded as powerful and active contributors to genomic and chromosomal evolution. Paired with mobile transposable elements, these repetitive sequences provide a dynamic mechanism through which novel karyotypic modifications and ...

Centromere domain organization and histone modifications

open access: yesBrazilian Journal of Medical and Biological Research, 2002
Centromere function requires the proper coordination of several subfunctions, such as kinetochore assembly, sister chromatid cohesion, binding of kinetochore microtubules, orientation of sister kinetochores to opposite spindle poles, and their movement ...

Comparative Analysis of Tandem Repeats from Hundreds of Species Reveals Unique Insights into Centromere Evolution [PDF]

open access: yesGenome Biology 2013, 2012
Centromeres are essential for chromosome segregation, yet their DNA sequences evolve rapidly. In most animals and plants that have been studied, centromeres contain megabase-scale arrays of tandem repeats. Despite their importance, very little is known about the degree to which centromere tandem repeats share common properties between different species

ATP-driven separation of liquid phase condensates in bacteria [PDF]

open access: yesMolecular Cell, 2020, Pages 293-303.e4, 2020
Liquid-liquid phase separated (LLPS) states are key to compartmentalise components in the absence of membranes, however it is unclear whether LLPS condensates are actively and specifically organized in the sub-cellular space and by which mechanisms.
