Histone Recycling by FACT and Spt6 during Transcription Prevents the Scrambling of Histone Modifications

open access: yesCell Reports, 2019
Summary: Genomic DNA is framed by additional layers of information, referred to as the epigenome. Epigenomic marks such as DNA methylation, histone modifications, and histone variants are concentrated on specific genomic sites, where they can both ...

Histone variants in skeletal myogenesis

open access: yesEpigenetics, 2021
Histone variants regulate chromatin accessibility and gene transcription. Given their distinct properties and functions, histone varint substitutions allow for profound alteration of nucleosomal architecture and local chromatin landscape.

Measuring Nucleosome Assembly Activity in vitro with the Nucleosome Assembly and Quantification (NAQ) Assay

open access: yesBio-Protocol, 2018
Nucleosomes organize the eukaryotic genome into chromatin. In cells, nucleosome assembly relies on the activity of histone chaperones, proteins with high binding affinity to histones. At least a subset of histone chaperones promotes histone deposition in

New chaps in the histone chaperone arena [PDF]

open access: yesGenes & Development, 2010
Understanding exactly how chromatin is assembled is paramount to addressing how select histone modifications may be transmitted, a putative epigenetic process. In the June 15, 2010, issue of Genes & Development, Drané and colleagues (pp. 1253–1265) identified DAXX as a novel H3.3-specific chaperone.

The Histone Chaperone FACT Contributes to DNA Replication-Coupled Nucleosome Assembly

open access: yesCell Reports, 2016
Summary: DNA replication-coupled (RC) nucleosome assembly is mediated by histone chaperones and is fundamental for epigenetic inheritance and maintenance of genomic integrity. The mechanisms that promote this process are only partially understood.

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

open access: yesHepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

Histone Chaperone Nrp1 Mutation Affects the Acetylation of H3K56 in Tetrahymena thermophila

open access: yesCells, 2022
Histone modification and nucleosome assembly are mainly regulated by various histone-modifying enzymes and chaperones. The roles of histone-modification enzymes have been well analyzed, but the molecular mechanism of histone chaperones in histone ...

Histone Variants: Guardians of Genome Integrity

open access: yesCells, 2020
Chromatin integrity is key for cell homeostasis and for preventing pathological development. Alterations in core chromatin components, histone proteins, recently came into the spotlight through the discovery of their driving role in cancer.

Histone variant H2A.B-H2B dimers are spontaneously exchanged with canonical H2A-H2B in the nucleosome

open access: yesCommunications Biology, 2021
Hirano et al. show that the H2A.B-H2B histone dimer incorporated within the nucleosome exchanges with the canonical H2A-H2B dimer without assistance from histone chaperones or nucleosome remodelers.

Histones and their chaperones: Adaptive remodelers of an ever-changing chromatinic landscape

open access: yesFrontiers in Genetics, 2022
Chromatin maintenance and remodeling are processes that take place alongside DNA repair, replication, or transcription to ensure the survival and adaptability of a cell.
