Capturing Chromosome Conformation
TLDR
Using the yeast Saccharomyces cerevisiae, this work could confirm known qualitative features of chromosome organization within the nucleus and dynamic changes in that organization during meiosis and found that chromatin is highly flexible throughout.Abstract:
We describe an approach to detect the frequency of interaction between any two genomic loci. Generation of a matrix of interaction frequencies between sites on the same or different chromosomes reveals their relative spatial disposition and provides information about the physical properties of the chromatin fiber. This methodology can be applied to the spatial organization of entire genomes in organisms from bacteria to human. Using the yeast Saccharomyces cerevisiae, we could confirm known qualitative features of chromosome organization within the nucleus and dynamic changes in that organization during meiosis. We also analyzed yeast chromosome III at the G1 stage of the cell cycle. We found that chromatin is highly flexible throughout. Furthermore, functionally distinct AT- and GC-rich domains were found to exhibit different conformations, and a population-average 3D model of chromosome III could be determined. Chromosome III emerges as a contorted ring.read more

TL;DR: Hi-C is described, a method that probes the three-dimensional architecture of whole genomes by coupling proximity-based ligation with massively parallel sequencing and demonstrates the power of Hi-C to map the dynamic conformations of entire genomes.

TL;DR: In situ Hi-C is used to probe the 3D architecture of genomes, constructing haploid and diploid maps of nine cell types, identifying ∼10,000 loops that frequently link promoters and enhancers, correlate with gene activation, and show conservation across cell types and species.

Histone methylation: a dynamic mark in health, disease and inheritance
Eric L. Greer,Yang Shi +1 more
TL;DR: This work provides a broad overview of how histone methylation is regulated and leads to biological outcomes and suggests its links to disease and ageing and possibly to transmission of traits across generations are illustrated.

Chromosome territories, nuclear architecture and gene regulation in mammalian cells.
TL;DR: The emerging view is that chromosomes are compartmentalized into discrete territories and the location of a gene within a chromosome territory seems to influence its access to the machinery responsible for specific nuclear functions, such as transcription and splicing.

TL;DR: In this paper, it was shown that the abscissa of the intersecting point of the 1/v2 and 1 /v branches, when extrapolated to the transition region, is connected in a characteristic way with the statistical chain element or the length of persistance, which represent two different measures for the stiffness of the chain molecule.
