Utilization of Host Cell Chromosome Conformation by Viral Pathogens: Knowing When to Hold and When to Fold

open access: yesFrontiers in Immunology, 2021
Though viruses have their own genomes, many depend on the nuclear environment of their hosts for replication and survival. A substantial body of work has therefore been devoted to understanding how viral and eukaryotic genomes interact.

The CTCF Anatomy of Topologically Associating Domains [PDF]

open access: yes, 2019
Abstract Topologically associated domains (TADs) are defined as regions of self-interaction. To date, it is unclear how to reconcile TAD structure with CTCF site orientation, which is known to coordinate chromatin loops anchored by Cohesin rings at convergent CTCF site pairs.

Enhancer Chromatin and 3D Genome Architecture Changes from Naive to Primed Human Embryonic Stem Cell States

open access: yesStem Cell Reports, 2019
Summary: During mammalian embryogenesis, changes in morphology and gene expression are concurrent with epigenomic reprogramming. Using human embryonic stem cells representing the preimplantation blastocyst (naive) and postimplantation epiblast (primed ...

Disruption of topologically associating domains by structural variations in tetraploid cottons

open access: yesGenomics, 2021
Structural variations (SVs) are recognized to have an important role in transcriptional regulation, especially in the light of resolved 3D genome structure using high-throughput chromosome conformation capture (Hi-C) technology in mammals. However, the effect of SVs on 3D genome organization in plants remains rarely understood.

Mapping chromosome neighborhoods

open access: yesBioTechniques, 2015
The discovery of topologically associating domains (TADs) changed the way researchers think about gene expression and chromosome structure. Jeffrey Perkel takes a closer look into these “chromosome neighborhoods.”

HiCmapTools: a tool to access HiC contact maps

open access: yesBMC Bioinformatics, 2022
Background With the development of HiC technology, more and more HiC sequencing data have been produced. Although there are dozens of packages that can turn sequencing data into contact maps, there is no appropriate tool to query contact maps in order to

Structural Fluctuations of the Chromatin Fiber within Topologically Associating Domains [PDF]

open access: yesBiophysical Journal, 2016
Experiments based on chromosome conformation capture have shown that mammalian genomes are partitioned into topologically associating domains (TADs), within which the chromatin fiber preferentially interacts. TADs may provide three-dimensional scaffolds allowing genes to contact their appropriate distal regulatory DNA sequences (e.g., enhancers) and ...

Modeling tissue-specific breakpoint proximity of structural variations from whole-genomes to identify cancer drivers

open access: yesNature Communications, 2022
Identifying structural variants (SVs) under positive selection in cancer is challenging. Here, the authors develop CSVDriver, a method that computes SV breakpoint proximity and the contribution of elements such as topologically associating domains, and ...

Topologically Associated Domains Delineate Susceptibility to Somatic Hypermutation

open access: yesCell Reports, 2019
Somatic hypermutation (SHM) introduces point mutations into immunoglobulin (Ig) genes but also causes mutations in other parts of the genome. We have used lentiviral SHM reporter vectors to identify regions of the genome that are susceptible ("hot") and resistant ("cold") to SHM, revealing that SHM susceptibility and resistance are often properties of ...
