Electrophoresis of positioned nucleosomes [PDF]
Biophysical Journal, 2006 We present in this paper an original approach to compute the electrophoretic mobility of rigid nucleo-protein complexes like nucleosomes. This model allows to address theoretically the influence of complex position along DNA, as well as wrapped length of

The size of the nucleosome [PDF]
, 2011 The structural origin of the size of the 11 nm nucleosomal disc is addressed. On the nanometer length-scale the organization of DNA as chromatin in the chromosomes involves a coiling of DNA around the histone core of the nucleosome.

Physical Review Letters, 2008 We present a statistical-mechanical analysis of the positioning of nucleosomes along one of the chromosomes of yeast DNA as a function of the strength of the binding potential and of the chemical potential of the nucleosomes. We find a significant density of two-level nucleosome switching regions where, as a function of the chemical potential, the ...

Proceedings of the National Academy of Sciences, 1997 Archaeacontain histones that have primary sequences in common with eukaryal nucleosome core histones and a three-dimensional structure that is essentially only the histone fold. Here we report the results of experiments that document that archaeal histones compact DNAin vivointo structures similar to the structure formed by the histone (H3+H4)2tetramer

A systematic analysis of nucleosome core particle and nucleosome-nucleosome stacking structure [PDF]
Scientific Reports, 2018 AbstractChromatin condensation is driven by the energetically favourable interaction between nucleosome core particles (NCPs). The close NCP-NCP contact, stacking, is a primary structural element of all condensed states of chromatin in vitro and in vivo.

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 ...

Reciprocal intronic and exonic histone modification regions in humans. [PDF]
, 2010 While much attention has been focused on chromatin at promoters and exons, human genes are mostly composed of intronic sequences. Analyzing published surveys of nucleosomes and 41 chromatin marks in humans, we identified histone modifications ...

Analysis of nucleosome repositioning by yeast ISWI and Chd1 chromatin remodeling complexes [PDF]
, 2006 ISWI proteins form the catalytic core of a subset of ATP-dependent chromatin remodelling activities in eukaryotes from yeast to man. Many of these complexes have been found to reposition nucleosomes, but with different directionalities.

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.
