Aspirin‐Derived Salicyl‐CoA Drives Histone Lysine Salicylation Regulated by CBP and SIRT2

open access: yesAdvanced Science, EarlyView.
Aspirin‐derived salicyl‐CoA serves as a previously unrecognized acyl donor for protein lysine salicylation. This study identifies histone lysine salicylation as a reversible epigenetic modification regulated by CBP and SIRT2, expanding the biochemical actions of aspirin beyond its canonical acetylation‐dependent mechanisms and providing a new framework

Analysis of Jmjd6 cellular localization and testing for its involvement in histone demethylation. [PDF]

open access: yes, 2010
Methylation of residues in histone tails is part of a network that regulates gene expression. JmjC domain containing proteins catalyze the oxidative removal of methyl groups on histone lysine residues.

Aberrant histone modifications in pediatric brain tumors

open access: yesFrontiers in Oncology
Epigenetic modifications, particularly histone post-translational modifications (PTMs), are central to pediatric brain tumor pathogenesis, impacting chromatin structure, gene expression, and genomic stability.

Histone Acetylation in Fungal Pathogens of Plants

open access: yesThe Plant Pathology Journal, 2014
Acetylation of histone lysine residues occurs in different organisms ranging from yeast to plants and mammals for the regulation of diverse cellular processes. With the identification of enzymes that create or reverse this modification, our understanding

GSLR Drives Lung Adenocarcinoma as a Critical Regulator of Energy Homeostasis Through Creatine Kinase B Activation

open access: yesAdvanced Science, EarlyView.
This study identifies the glucose/glutamine sensitive lncRNA GSLR as a driver of lung adenocarcinoma progression. Nutrient restriction reduces chromatin accessibility at the GSLR locus and blocks CTCF‐mediated transcriptional regulation. GSLR directly interacts with DHX9 and recruits it to the CKB promoter, arresting R‐loop accumulation and promoting ...

The histone chaperones Vps75 and Nap1 form ring-like, tetrameric structures in solution [PDF]

open access: yes, 2013
NAP-1 fold histone chaperones play an important role in escorting histones to and from sites of nucleosome assembly and disassembly. The two NAP-1 fold histone chaperones in budding yeast, Vps75 and Nap1, have previously been crystalized in a ...

SCTR–Expressing Astrocyte–Serotonergic Neuron Signaling Drives Sexual Dimorphism in Depression Through KAT7/H4ac–Foxc2 Epigenetic Axis in an AMPK‐Dependent Manner

open access: yesAdvanced Science, EarlyView.
Astrocytic SCTR modulates depressive‐related phenotypes via AMPKα1, whereas lowered Mt1 blunts Megalin‐dependent AMPKα2 signaling in serotonergic neurons. Diminished AMPKα2 hinders KAT7 nuclear translocation, curtails KAT7 occupancy and H4K8ac at the Foxc2 promoter, and represses Foxc2 transcription, revealing cell‐type‐specific AMPK‐linked epigenetic ...

Identification of Long Chain Alkylidenemalonates as Novel Small Molecule Modulators of Histone Acetyltransferases

open access: yes, 2008
Pentadecylidenemalonate 1b, a simplified analogue of anacardic acid, was identified as the first mixed activator/inhibitor of histone acetyltransferases (HATs). It potentiates PCAF HAT activity while inhibiting those of p300/CBP and recombinant CBP.

Acetylation of histone H3 at lysine 64 regulates nucleosome dynamics and facilitates transcription [PDF]

open access: yes, 2014
Post-translational modifications of proteins have emerged as a major mechanism for regulating gene expression. However, our understanding of how histone modifications directly affect chromatin function remains limited.

Histones post-translational modifications associated with the development of metabolic dysfunction-associated fatty liver disease. Part 3. Histon acetylation

open access: yesGastroenterologìa
Based on the analysis of literature sources from the Pubmed, MEDLINE, The Cochrane Library, Embase databases, the authors of the article highlight general provisions regarding histone acetylation.
