Nucleosome Switches [PDF]

open access: yesPhysical Review Letters, 2008
We present a statistical-mechanical model for the positioning of nucleosomes along genomic DNA molecules as a function of the strength of the binding potential and the chemical potential of the nucleosomes. We show that a significant section of the DNA is composed of two-level nucleosome switching regions where the nucleosome distribution undergoes a ...

Inter-nucleosomal potentials from nucleosomal positioning data

open access: yesThe European Physical Journal E, 2022
AbstractNo systematic method exists to derive inter-nucleosomal potentials between nucleosomes along a chromosome consistently across a given genome. Such potentials can yield information on nucleosomal ordering, thermal as well as mechanical properties of chromosomes.

Cellular uptake of extracellular nucleosomes induces innate immune responses by binding and activating cGMP-AMP synthase (cGAS)

open access: yesScientific Reports, 2020
The nucleosome is the basic structural repeating unit of chromatin. DNA damage and cell apoptosis release nucleosomes into the blood circulatory system, and increased levels of circulating nucleosomes have been observed to be related to inflammation and ...

A species-specific nucleosomal signature defines a periodic distribution of amino acids in proteins [PDF]

open access: yesOpen Biology, 2015
Nucleosomes are the basic structural units of chromatin. Most of the yeast genome is organized in a pattern of positioned nucleosomes that is stably maintained under a wide range of physiological conditions.

Nucleosome Positioning, Nucleosome Spacing and the Nucleosome Code [PDF]

open access: yesJournal of Biomolecular Structure and Dynamics, 2010
Nucleosome positioning has been the subject of intense study for many years. The properties of micrococcal nuclease, the enzyme central to these studies, are discussed. The various methods used to determine nucleosome positions in vitro and in vivo are reviewed critically.

EXTRACELLULAR DNA AND THE LEVEL OF ITS METHYLATION IN DIFFERENT RHEUMATIC DISEASES

open access: yesНаучно-практическая ревматология, 2012
Objective: to study the qualitative and quantitative composition of serum extracellular DNA (exDNA); apoptotic (nucleosomes) and necrotic fragmentation; complexification of monometinic proteins with exDNA; and the levels of exDNA methylation as compared ...

Nucleosome—nucleosome interaction in chromatin

open access: yesFEBS Letters, 1979
The available data suggest that transcriptional activity of chromatin is connected with its structural changes [ 1,2]. According to the electron microscope evidence, the elementary 100 A chromatin thread can exist in two main states, i.e., in a compact state, which is characterized by tight packing of nucleosomes and in an extended state when the ...

Gammaretroviruses tether to mitotic chromatin by directly binding nucleosomal histone proteins

open access: yesMicrobial Cell, 2018
The gammaretroviral gag cleavage product, p12, is essential for replication at both early and late stages of the virus life cycle. During the early stage of infection, the viral core is released into the cytoplasm, the viral RNA genome is reversed ...

The Role of Histone Variants in the Epithelial-To-Mesenchymal Transition

open access: yesCells, 2020
The epithelial-to-mesenchymal transition (EMT) is a physiological process activated during early embryogenesis, which continues to shape tissues and organs later on. It is also hijacked by tumor cells during metastasis. The regulation of EMT has been the
