A barrier nucleosome model for statistical positioning of nucleosomes throughout the yeast genome.
Most nucleosomes are well-organized at the 5' ends of S. cerevisiae genes where "-1" and "+1" nucleosomes bracket a nucleosome-free promoter region (NFR). How nucleosomal organization is specified by the genome is less clear.

7,12‐Dimethylbenz[a]anthracene (DMBA) could induce leukemia and other types of cancers in rat models. Transcriptomics revealed gene expression profile that parallels with human leukemia. DMBA‐induced differential gene expression could validate the developed rat model.

What's New? This study introduces a novel approach for detecting locally advanced esophageal carcinoma using cell‐free DNA (cfDNA) analysis through a highly sensitive fragmentome assay. Unlike traditional sequencing‐based methods that are limited by the absence of specific mutations in esophageal tumors, our method offers an alternative by quantifying ...

DNA-spools, structures in which DNA is wrapped and helically coiled onto itself or onto a protein core are ubiquitous in nature. We develop a general theory describing the non-equilibrium behavior of DNA-spools under linear tension.

Epigenetic Regulation in the Pathogenesis of Renal Inflammation: Insights and Therapeutic Potentials
ABSTRACT Renal inflammation is a common pathological process in various kidney diseases, often initiated by factors such as toxins, ischemia, or autoimmune reactions. This inflammatory response can result in structural damage and a rapid decline in renal function.

Theory of Nucleosome Corkscrew Sliding in the Presence of Synthetic DNA Ligands
Histone octamers show a heat-induced mobility along DNA. Recent theoretical studies have established two mechanisms that are qualitatively and quantitatively compatible with in vitro experiments on nucleosome sliding: Octamer repositiong through one ...

SUMOylation, a dynamic post‐translational modification, acts as a master regulator at the heart of tumor malignancy. Our work delineates how the SUMOylation cycle—mediated by E1/E2/E3 enzymes and reversed by SENPs—orchestrates multiple hallmarks of cancer. The central pathway converges on three critical pathological axes: 1.

PRDM9 binding organizes hotspot nucleosomes and limits Holliday junction migration
In mammals, genetic recombination during meiosis is limited to a set of 1- to 2-kb regions termed hotspots. Their locations are predominantly determined by the zinc finger protein PRDM9, which binds to DNA in hotspots and subsequently uses its SET domain
