The Texture of Chromatin [PDF]

open access: yesCell, 2019
DNA-replication machinery introduces intertwining and supercoiling of DNA strands as it traverses the double helix, which could impede replication and compromise genome stability. A new study in Cell shows that the intrinsic physical properties of chromatin fibers dictate how torsional stress is partitioned to minimize these risks and facilitate DNA ...

Transposable Element Dynamics and Regulation during Zygotic Genome Activation in Mammalian Embryos and Embryonic Stem Cell Model Systems

open access: yesStem Cells International, 2021
Transposable elements (TEs) are mobile genetic sequences capable of duplicating and reintegrating at new regions within the genome. A growing body of evidence has demonstrated that these elements play important roles in host genome evolution, despite ...

Investigation of the acetic acid stress response in Saccharomyces cerevisiae with mutated H3 residues

open access: yesMicrobial Cell, 2023
Enhanced levels of acetic acid reduce the activity of yeast strains employed for industrial fermentation-based applications. Therefore, unraveling the genetic factors underlying the regulation of the tolerance and sensitivity of yeast towards acetic acid

Spermatid-specific linker histone HILS1 is a poor condenser of DNA and chromatin and preferentially associates with LINE-1 elements

open access: yesEpigenetics & Chromatin, 2018
Background Linker histones establish and maintain higher-order chromatin structure. Eleven linker histone subtypes have been reported in mammals. HILS1 is a spermatid-specific linker histone, and its expression overlaps with the histone–protamine ...

Cytoplasmic chromatin triggers inflammation in senescence and cancer [PDF]

open access: yes, 2017
Chromatin is traditionally viewed as a nuclear entity that regulates gene expression and silencing. However, we recently discovered the presence of cytoplasmic chromatin fragments that pinch off from intact nuclei of primary cells during senescence, a ...

Quantifying nuclear wide chromatin compaction by phasor analysis of histone Förster resonance energy transfer (FRET) in frequency domain fluorescence lifetime imaging microscopy (FLIM) data. [PDF]

open access: yes, 2020
The nanometer spacing between nucleosomes throughout global chromatin organisation modulates local DNA template access, and through continuous dynamic rearrangements, regulates genome function [1].

Rapid, solid-phase based automated analysis of chromatin structure and transcription factor occupancy in living eukaryotic cells [PDF]

open access: yes, 2005
Transcription factors, chromatin components and chromatin modification activities are involved in many diseases including cancer. However, the means by which alterations in these factors influence the epigenotype of specific cell types is poorly ...

Distinct roles of haspin in stem cell division and male gametogenesis

open access: yesScientific Reports, 2021
The kinase haspin phosphorylates histone H3 at threonine-3 (H3T3ph) during mitosis. H3T3ph provides a docking site for the Chromosomal Passenger Complex at the centromere, enabling correction of erratic microtubule-chromosome contacts.

Control of human adenovirus type 5 gene expression by cellular Daxx/ATRX chromatin-associated complexes [PDF]

open access: yes, 2013
Death domain–associated protein (Daxx) cooperates with X-linked α-thalassaemia retardation syndrome protein (ATRX), a putative member of the sucrose non-fermentable 2 family of ATP-dependent chromatin-remodelling proteins, acting as the core ATPase ...

Comprehensive analysis of the chromatin landscape in Drosophila melanogaster. [PDF]

open access: yes, 2010
Chromatin is composed of DNA and a variety of modified histones and non-histone proteins, which have an impact on cell differentiation, gene regulation and other key cellular processes.
