Circulating Nucleosomes and Nucleosome Modifications as Biomarkers in Cancer [PDF]
Cancers, 2017 Traditionally the stratification of many cancers involves combining tumour and clinicopathological features (e.g., patient age; tumour size, grade, receptor status and location) to inform treatment options and predict recurrence risk and survival. However, current biomarkers often require invasive excision of the tumour for profiling, do not allow ...

Scientific 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 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]
Journal 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
Научно-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 ...

Gammaretroviruses tether to mitotic chromatin by directly binding nucleosomal histone proteins
Microbial 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 ...

Nucleosome—nucleosome interaction in chromatin
FEBS 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 ...

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

Dissociation rate compensation mechanism for budding yeast pioneer transcription factors
eLife, 2019 Nucleosomes restrict the occupancy of most transcription factors (TF) by reducing binding and accelerating dissociation, while a small group of TFs have high affinities to nucleosome-embedded sites and facilitate nucleosome displacement.
