Topologically Associated Domains Delineate Susceptibility to Somatic Hypermutation

open access: yesCell Reports, 2019
Somatic hypermutation (SHM) introduces point mutations into immunoglobulin (<i>Ig</i>) genes of activated B cells to support the process of antibody affinity maturation but also causes "off-target" mutations in other parts of the genome. We have used sensitive lentiviral SHM reporter vectors and a mutationally active human B cell line to ...

Deciphering the species-level structure of topologically associating domains [PDF]

open access: yes, 2021
Summary Chromosome conformation capture technologies such as Hi-C have revealed a rich hierarchical structure of chromatin, with topologically associating domains (TADs) as a key organizational unit, but experimentally reported TAD architectures, currently determined separately for each cell type, are lacking for many

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 ...

SuperTAD: robust detection of hierarchical topologically associated domains with optimized structural information

open access: yesGenome Biology, 2021
Topologically associating domains (TADs) are the organizational units of chromosome structures. TADs can contain TADs, thus forming a hierarchy. TAD hierarchies can be inferred from Hi-C data through coding trees.

Parvovirus minute virus of mice interacts with sites of cellular DNA damage to establish and amplify its lytic infection

open access: yeseLife, 2018
We have developed a generally adaptable, novel high-throughput Viral Chromosome Conformation Capture assay (V3C-seq) for use in trans that allows genome-wide identification of the direct interactions of a lytic virus genome with distinct regions of the ...

Order and stochasticity in the folding of individual Drosophila genomes

open access: yesNature Communications, 2021
Genomes are partitioned into topologically associating domains (TADs). Here the authors present single-nucleus Hi-C maps in Drosophila at 10 kb resolution, demonstrating the presence of chromatin compartments in individual nuclei, and partitioning of the

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

open access: yesFEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Topological organization and dynamic regulation of human tRNA genes during macrophage differentiation

open access: yesGenome Biology, 2017
Background The human genome is hierarchically organized into local and long-range structures that help shape cell-type-specific transcription patterns.

A comparison of topologically associating domain callers over mammals at high resolution

open access: yesBMC Bioinformatics, 2022
Background Topologically associating domains (TADs) are locally highly-interacting genome regions, which also play a critical role in regulating gene expression in the cell. TADs have been first identified while investigating the 3D genome structure over
