A hypothetical trivalent epigenetic code that affects the nature of human ESCs
It has been suggested that DNA methylation can work in concert with other epigenetic factors, leading to changes in cellular phenotypes. For example, DNA demethylation modifications producing 5-hydroxymethylcytosine (5hmC) are thought to interact with ...

Nonlinearities and Switch‐Like Behavior in Gene Expression: From Genetics to Biochemistry and Back
Modest changes in transcription‐factor or chromatin‐regulator dosage can have disproportionate effects when gene‐regulatory systems operate near nonlinear thresholds. Sigmoidal input–output relationships, chromatin and cofactor recruitment, and changes in threshold position or response steepness provide molecular routes by which quantitative dosage ...

This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.

HER2 is a transmembrane receptor tyrosine kinase, which plays a key role in breast cancer due to a common genomic amplification. It is used as a marker to stratify patients in the clinic and is targeted by a number of drugs including Trastuzumab and ...

A non‐canonical core transcriptional regulatory circuit, composed of ID3, SMAD3, and NR2F2, drives Osimertinib resistance in non‐small cell lung cancer through super‐enhancer‐mediated activation of EPAS1, which couples neuroendocrine differentiation with ferroptosis evasion.

This study reveals a metabolic signaling axis in the OSCC microenvironment where palmitic acid (PA) drives the activation of CAFs. PA uptake triggers CEBPG‐dependent epigenetic remodeling to upregulate ERN1 and TMBIM6, thereby mitigating ER stress. This adaptive program sustains CAF survival and the pro‐metastatic phenotype, establishing this pathway ...

CTBP1‐driven CETP activation orchestrates lipid accumulation to suppress MAPK‐dependent ferroptosis in non‐small cell lung cancer. Repurposing the clinical‐stage CETP inhibitor obicetrapib successfully overcomes this resistance in NSCLC patient‐derived organoids, highlighting a promising translational therapeutic strategy. Abstract Background Non‐small

Molecular Acrobats: How CHD Remodelers Shape the Genetic Playground to License Cell Identity
ABSTRACT In eukaryotes, DNA is not a naked repository of genetic information but is tightly wound around histone octamers to form nucleosomes. While this packaging solves the spatial problem of fitting 2 meters of DNA into a microscopic nucleus, it creates a massive accessibility problem for DNA‐templated events, including transcription, replication ...

Histone lysine methyltransferase 2D (KMT2D/MLL4) critically modulates gene expression by methylating and acetylating histones H3K4/H3K27, thereby regulating the expression of specific target genes. Although KMT2D is highly mutated in a variety of cancers, its role in the progression of oral squamous cell carcinoma (OSCC) remains unclear. The purpose of

Seed development involves a plethora of spatially and temporally synchronised genetic and epigenetic processes. Although it has been shown that epigenetic mechanisms, such as DNA methylation and chromatin remodelling, act on a large number of genes ...
