Sequential in cis mutagenesis in vivo reveals various functions for CTCF sites at the mouse HoxD cluster

Denis Duboule, Jozsef Zakany, Lucille Delisle, Leonardo Beccari

In this study, Amandio et al. sought to understand the functions of the highly conserved CTCF sites distributed over the Hox gene clusters. The authors produced an allelic series of cumulative in cis mutations in these sites, up to the abrogation of CTCF b ...

CTCF loss has limited effects on global genome architecture in Drosophila despite critical regulatory functions

Christian Iseli, Nicolas Jean Philippe Guex, Julien Dorier, Flavia Marzetta

Vertebrate genomes are partitioned into contact domains defined by enhanced internal contact frequency and formed by two principal mechanisms: compartmentalization of transcriptionally active and inactive domains, and stalling of chromosomal loop-extruding ...

Damage-driven strain localisation in networks of fibres: A computational homogenisation approach

Pablo Antolin Sanchez, Felipe Figueredo Rocha

In many applications, such as textiles, fibreglass, paper and several kinds of biological fibrous tissues, the main load-bearing constituents at the micro-scale are arranged as a fibre network. In these materials, rupture is usually driven by micro-mechani ...

Oscillating and stable genome topologies underlie hepatic physiological rhythms during the circadian cycle

Felix Naef, Jake Yeung, Jérôme Mermet

The circadian clock drives extensive temporal gene expression programs controlling daily changes in behavior and physiology. In mouse liver, transcription factors dynamics, chromatin modifications, and RNA Polymerase II (PolII) activity oscillate throughou ...

Histone acetylation dynamics modulates chromatin conformation and allele-specific interactions at oncogenic loci

Elisa Oricchio, Natalya Katanayeva, Daniele Tavernari, Stephanie Jocelyne Sungalee, Ruxandra-Andreea Lambuta, Giovanni Ciriello

In cancer cells, enhancer hijacking mediated by chromosomal alterations and/or increased deposition of acetylated histone H3 lysine 27 (H3K27ac) can support oncogene expression. However, how the chromatin conformation of enhancer-promoter interactions is a ...

Notch1-driven T-ALL chromatin landscape is regulated by Tcf1 in hematopoietic progenitors

Mateusz Waldemar Antoszewski

Notch1 receptor signaling is essential for T cell fate specification and physiological thymic T lymphocyte development. Its dysregulation and oncogenic activation are detected in almost 80% of pediatric patients suffering from T cell acute lymphoblastic le ...

Multiplexed Single-Molecule Experiments Reveal Nucleosome Invasion Dynamics of the Cas9 Genome Editor

Beat Fierz, Louise Catherine Bryan, Kristina Makasheva

Single-molecule measurements provide detailed mechanistic insights into molecular processes, for example in genome regulation where DNA access is controlled by nucleosomes and the chromatin machinery. However, real-time single-molecule observations of nucl ...

Dynamic Chromatin Invasion and Remodeling by the Transcription Factor Rap1

Maxime Nicolas Mivelaz

Pioneer transcription factors (PTF) are a subset of transcription factors with nucleosome-binding properties allowing them to bind specific sequences in condensed chromatin. Although the biological functions of PTFs including target genes and epigenetic ch ...

The box C/D snoRNP assembly factor Bcd1 interacts with the histone chaperone Rtt106 and controls its transcription dependent activity

Benjamin Marcel Daniel Rothé

Biogenesis of eukaryotic box C/D small nucleolar ribonucleoproteins initiates co-transcriptionally and requires the action of the assembly machinery including the Hsp90/R2TP complex, the Rsa1p:Hit1p heterodimer and the Bcd1 protein. We present genetic inte ...

Induction of a chromatin boundary in vivo upon insertion of a tad border

Denis Duboule, Christopher Chase Bolt, Lucille Delisle, Edgardo Rodriguez Carballo, Marie-Laure Gadolini

Author summary During development, enhancer sequences tightly regulate the spatio-temporal expression of target genes often located hundreds of kilobases away. This complex process is made possible by the folding of chromatin into domains, which are separa ...
