A CTCF-dependent mechanism underlies the Hox timer relation to a segmented body plan
During gastrulation, Hox genes are activated in a timesequence that follows the order of the genes along their clusters. This property, which is observed in all animals that develop following a progressive rostral-to-caudal morphogenesis, is associated wit ...
Current Biology Ltd2024Decoding Chromatin Ubiquitylation: A Chemical Biology Perspective
Since Strahl and Allis proposed the "language of covalent histone modifications", a host of experimental studies have shed light on the different facets of chromatin regulation by epigenetic mechanisms. Initially proposed as a concept for controlling gene ...
Academic Press Ltd- Elsevier Science Ltd2024Chromatin organization in red triangles
This journal club by Elisa Oricchio highlights two studies published in 2012, which used chromatin conformation capture methods to detect the formation of self-interacting chromatin regions, known as topologically associating domains (TADs). ...
NATURE PORTFOLIO2023Whole genome doubling promotes tumorigenesis through loss of chromatin segregation and compartment repositioning
Whole genome doubling (WGD) events are drivers of genetic innovation across vertebrate evolution. While generally detrimental to mammalian organisms, WGDs are crucial in the development of various plants and fungi, as well as for the terminal differentiati ...
EPFL2023Sequential and directional insulation by conserved CTCF sites underlies the Hox timer in stembryos
Denis Duboule, Lucille Delisle, Alexandre Gauthier Aurèle Mayran, Hocine Rekaik, Aurélie Hintermann, Célia Corinne Renée Bochaton
Temporal activation of Hox genes in mouse pseudo-embryos in vitro initiates at the anterior part of the cluster and is accompanied by asymmetric loading of cohesin. Posterior CTCF sites then successively act as transient insulators, regulating the timed tr ...
NATURE PORTFOLIO2023Centromere structure and function: lessons from Drosophila
The fruit fly Drosophila melanogaster serves as a powerful model organism for advancing our understanding of biological processes, not just by studying its similarities with other organisms including ourselves but also by investigating its differences to u ...
Bethesda2023Chromatin modules and their implication in genomic organization and gene regulation
Bart Deplancke, Guido Van Mierlo, Judith Franziska Kribelbauer
Regulation of gene expression is a complex but highly guided process. While genomic technologies and computational approaches have allowed high-throughput mapping of cis-regulatory elements (CREs) and their interactions in 3D, their precise role in regulat ...
ELSEVIER SCIENCE LONDON2023Essential role of Cp190 in physical and regulatory boundary formation
Nicolas Jean Philippe Guex, Julien Dorier, Christian Iseli
Boundaries in animal genomes delimit contact domains with enhanced internal contact frequencies and have debated functions in limiting regulatory cross-talk between domains and guiding enhancers to target promoters. Most mammalian boundaries form by stalli ...
2022Context-dependent enhancer function revealed by targeted inter-TAD relocation
Denis Duboule, Lucille Delisle, Guillaume Andrey, Christopher Chase Bolt, Aurélie Hintermann
Here the authors show that a strong enhancer sequence can be controlled by the chromatin environment provided by a topologically associated domain (TAD) located nearby. An enhancer relocated by homologous recombination takes all the hallmarks of its new ne ...
NATURE PORTFOLIO2022CTCF loss has limited effects on global genome architecture in Drosophila despite critical regulatory functions
Nicolas Jean Philippe Guex, Julien Dorier, Christian Iseli, 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 ...
