WNT signaling coordinately controls mouse limb bud outgrowth and establishment of the digit-interdigit pattern

Alexandre Gauthier Aurèle Mayran, Lucille Delisle

Self-organization, such as the emergence of a pattern from a homogenous state, is a fascinating property of biological systems. Early limb bud outgrowth and patterning in mice are controlled by a robust and self-regulatory signaling system, and initiation ...

Size-dependent temporal decoupling of morphogenesis and transcriptional programs in pseudoembryos

Denis Duboule, Alexandre Gauthier Aurèle Mayran, Lucille Delisle

Understanding the interplay between cell fate specification and morphogenetic changes remains a challenge in developmental biology. Gastruloids, stem cell models of postimplantation mammalian development, provide a platform to address this question. Here, ...

Pre-hypertrophic chondrogenic enhancer landscape of limb and axial skeleton development

Lucille Delisle

Chondrocyte differentiation controls skeleton development and stature. Here we provide a comprehensive map of chondrocyte-specific enhancers and show that they provide a mechanistic framework through which non-coding genetic variants can influence skeletal ...

CTCF-dependent insulation of Hoxb13 and the heterochronic control of tail length

Denis Duboule, Alexandre Gauthier Aurèle Mayran, Hocine Rekaik, Lucille Delisle, Fabrice Daniel Darbellay, Célia Corinne Renée Bochaton, Pierre Osteil

Mammalian tail length is controlled by several genetic determinants, among which are Hox13 genes, whose function is to terminate the body axis. Accordingly, the precise timing in the transcriptional activation of these genes may impact upon body length. Un ...

Sequential and directional insulation by conserved CTCF sites underlies the Hox timer in stembryos

Denis Duboule, Alexandre Gauthier Aurèle Mayran, Hocine Rekaik, Célia Corinne Renée Bochaton, Lucille Delisle, Aurélie Hintermann

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 ...

Context-dependent enhancer function revealed by targeted inter-TAD relocation

Denis Duboule, Guillaume Andrey, Lucille Delisle, 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 ...

The Galaxy platform for accessible, reproducible and collaborative biomedical analyses: 2022 update

Lucille Delisle

Galaxy is a mature, browser accessible workbench for scientific computing. It enables scientists to share, analyze and visualize their own data, with minimal technical impediments. A thriving global community continues to use, maintain and contribute to th ...

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 ...

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 ...

Mesomelic dysplasias associated with the HOXD locus are caused by regulatory reallocations

Denis Duboule, Christopher Chase Bolt, Lucille Delisle

Mesomelic dysplasia, a severe shortening and bending of the limb, has been linked to rearrangements in the HoxD cluster in humans and mice. Here the authors engineer a 1 Mb inversion including the HoxD gene cluster and use this model to provide a mechanist ...
