Protein Glutamylation: From Cytoskeleton to Signaling

Med Research, EarlyView.
Tubulin glutamylation, γ‐glutamylation, and nontubulin glutamylation are distinct yet interconnected post‐translational modifications that regulate diverse physiological and pathological processes, including cytoskeletal organization, cell cycle progression, immunity, metabolism, and disease development.

The epigenetic landscape of plant defense: Unlocking nature's toolkit for new plant protection

New Plant Protection, EarlyView.
This review examines how epigenetic mechanisms regulate plant immune gene activation, repression, and priming, then links these natural regulatory layers to emerging epigenetic editing, discussing their potential for precise, heritable crop protection and the challenges.

A needed nomenclature for nucleosomes

Molecular Cell
Histone post-translational modifications (PTMs) are crucial to eukaryotic genome regulation, with a range of reported functions and mechanisms of action. Though often studied individually, it has long been recognized that the modifications function by combinatorial synergy or antagonism.

Epigenetic Regulation of Liver Fibrosis: Mechanisms and Therapeutic Implications

Portal Hypertension &Cirrhosis, EarlyView.
This review synthesizes the epigenetic mechanisms—DNA methylation, histone modifications, and non‐coding RNAs—that drive hepatic stellate cell activation and the progression of liver fibrosis. It further evaluates emerging therapeutic strategies targeting these epigenetic regulators, including DNA methyltransferase and histone deacetylase inhibitors ...

Divergence of nucleosome positioning between two closely related yeast species: genetic basis and functional consequences

Molecular Systems Biology, 2010
Gene regulation differs greatly between related species, constituting a major source of phenotypic diversity. Recent studies characterized extensive differences in the gene expression programs of closely related species. In contrast, virtually nothing is

Genomics and epigenomics of tissue repair: Implications for personalized medicine

Precision Medical Sciences, EarlyView.
Genomic and epigenomic mechanisms govern tissue repair and regeneration through dynamic regulation of inflammation, cell fate, and extracellular matrix remodeling. The integration of multi‐omics, artificial intelligence, and precision regenerative therapies enables biomarker‐driven, personalized approaches to enhance healing and minimize fibrosis ...

Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...

Genome-wide mapping and cryo-EM structural analyses of the overlapping tri-nucleosome composed of hexasome-hexasome-octasome moieties

Communications Biology
The nucleosome is a fundamental unit of chromatin in which about 150 base pairs of DNA are wrapped around a histone octamer. The overlapping di-nucleosome has been proposed as a product of chromatin remodeling around the transcription start site, and ...

Astragaloside IV Restores Autophagy and Inhibits Apoptosis for Podocyte Protection in Diabetic Nephropathy by Inhibiting Notch1 Signaling via SIRT6‐Mediated Deacetylation

Phytotherapy Research, EarlyView.
AS‐IV binds to SIRT6 and promotes H3K9 deacetylation at the Notch1 promoter, inhibiting gene transcription (Created with BioGDP.com). ABSTRACT Astragaloside IV (AS‐IV) has demonstrated efficacy in ameliorating proteinuria and attenuating renal tubular damage in preclinical diabetic nephropathy (DN) models.

Nature‐Inspired Histidine and Guanidine Modification of Magnetic Nanoparticles for Urinary DNA Liquid Biopsy

Small Methods, EarlyView.
Nature‐inspired bi‐functionalized magnetic nanoparticles are engineered for the rapid, non‐invasive extraction of cell‐free DNA from unprocessed urine for liquid biopsy. These cationic particles leverage electrostatic interactions to outperform conventional kits, enhancing the recovery of short DNA fragments while maintaining DNA integrity.
