Stochastic nucleosome disassembly mediated by remodelers and histone fragmentation [PDF]

open access: yesarXiv, 2023
We construct and analyze monomeric and multimeric models of the stochastic disassembly of a single nucleosome. Our monomeric model predicts the time needed for a number of histone-DNA contacts to spontaneously break, leading to dissociation of a non-fragmented histone from DNA.

The Hypersaline Archaeal Histones HpyA and HstA Are DNA Binding Proteins That Defy Categorization According to Commonly Used Functional Criteria

open access: yesmBio, 2023
Histone proteins are found across diverse lineages of Archaea, many of which package DNA and form chromatin. However, previous research has led to the hypothesis that the histone-like proteins of high-salt-adapted archaea, or halophiles, function ...

Histone Citrullination Mediates a Protective Role in Endothelium and Modulates Inflammation

open access: yesCells, 2022
NETosis is a key host immune process against a pathogenic infection during innate immune activation, consisting of a neutrophil “explosion” and, consequently, NET formation, containing mainly DNA, histones, and other nuclear proteins.

Transcriptional and Post-Transcriptional Regulation and Transcriptional Memory of Chromatin Regulators in Response to Low Temperature

open access: yesFrontiers in Plant Science, 2020
Chromatin regulation ensures stable repression of stress-inducible genes under non-stress conditions and transcriptional activation and memory of stress-related genes after stress exposure.

Structural Analysis of SMYD3 Lysine Methyltransferase for the Development of Competitive and Specific Enzyme Inhibitors

open access: yesDiseases, 2021
Lysine methylation is among the key posttranslational modifications to histones that contribute to epigenetic regulation. SMYD3 is a lysine methyltransferase that is essential for the proliferation of a range of tumorigenic cells. The findings that SMYD3

Blood levels of histone-complexed DNA fragments are associated with coagulopathy, inflammation and endothelial damage early after trauma

open access: yesJournal of Emergencies, Trauma and Shock, 2013
Background: Tissue injury increases blood levels of extracellular histones and nucleic acids, and these may influence hemostasis, promote inflammation and damage the endothelium. Trauma-induced coagulopathy (TIC) may result from an endogenous response to

H2A-H2B Histone Dimer Plasticity and Its Functional Implications

open access: yesCells, 2022
The protein core of the nucleosome is composed of an H3-H4 histone tetramer and two H2A-H2B histone dimers. The tetramer organizes the central 60 DNA bp, while H2A-H2B dimers lock the flanking DNA segments. Being positioned at the sides of the nucleosome,

A Proposal on Quantum Histone Modification in Gene Expression [PDF]

open access: yes, 2012
A quantum mechanical model on histone modification is proposed. Along with the methyl / acetate or other groups bound to the modified residues the torsion angles of the nearby histone chain are supposed to participate in the quantum transition cooperatively.

Current Approaches to Epigenetic Therapy

open access: yesEpigenomes, 2023
Epigenetic therapy is a promising tool for the treatment of a wide range of diseases. Several fundamental epigenetic approaches have been proposed. Firstly, the use of small molecules as epigenetic effectors, as the most developed pharmacological method,

Extracellular Acetylated Histone 3.3 Induces Inflammation and Lung Tissue Damage

open access: yesBiomolecules, 2023
Extracellular histones, part of the protein group known as damage-associated molecular patterns (DAMPs), are released from damaged or dying cells and can instigate cellular toxicity.
