Formation of Chromosomal Domains by Loop Extrusion

TL;DR: This model produces TADs and finer-scale features of Hi-C data because each TAD emerges from multiple loops dynamically formed through extrusion, contrary to typical illustrations of single static loops.
Journal ArticleDOI

Single-cell Hi-C reveals cell-to-cell variability in chromosome structure

TL;DR: Single-cell Hi-C data bridge current gaps between genomics and microscopy studies of chromosomes, demonstrating how modular organization underlies dynamic chromosome structure, and how this structure is probabilistically linked with genome activity patterns.
Journal ArticleDOI

Targeted Degradation of CTCF Decouples Local Insulation of Chromosome Domains from Genomic Compartmentalization.

TL;DR: The data support that CTCF mediates transcriptional insulator function through enhancer blocking but not as a direct barrier to heterochromatin spreading, and provides new fundamental insights into the rules governing mammalian genome organization.
Journal ArticleDOI

Modification of Enhancer Chromatin: What, How, and Why?

TL;DR: An overview of enhancer-associated modifications of histones and DNA is given and enzymatic activities involved in their dynamic deposition and removal are discussed and potential downstream effectors of these marks are described.
Journal ArticleDOI

Transcriptional enhancers: from properties to genome-wide predictions.

TL;DR: How properties of enhancer sequences and chromatin are used to predict enhancers in genome-wide studies are discussed and recently developed high-throughput methods that allow the direct testing and identification of enhancers on the basis of their activity are covered.

Initial sequencing and analysis of the human genome.

Eric S. Lander, +248 more
- 15 Feb 2001 - 
TL;DR: The results of an international collaboration to produce and make freely available a draft sequence of the human genome are reported and an initial analysis is presented, describing some of the insights that can be gleaned from the sequence.

Topological domains in mammalian genomes identified by analysis of chromatin interactions

TL;DR: It is found that the boundaries of topological domains are enriched for the insulator binding protein CTCF, housekeeping genes, transfer RNAs and short interspersed element (SINE) retrotransposons, indicating that these factors may have a role in establishing the topological domain structure of the genome.

Capturing Chromosome Conformation

TL;DR: 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.
