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 ...

Similarities and differences in the regulation of HoxD genes during chick and mouse limb development

Denis Duboule, Guillaume Andrey, Lucille Delisle, Christopher Chase Bolt, Leonardo Beccari, Nayuta Yakushiji

In all tetrapods examined thus far, the development and patterning of limbs require the activation of gene members of the HoxD cluster. In mammals, they are regulated by a complex bimodal process that controls first the proximal patterning and then the dis ...

Integration of Shh and Fgf signaling in controlling Hox gene expression in cultured limb cells

Denis Duboule, Guillaume Andrey, Patrick Schorderet, Nayuta Yakushiji

During embryonic development, fields of progenitor cells form complex structures through dynamic interactions with external signaling molecules. How complex signaling inputs are integrated to yield appropriate gene expression responses is poorly understood ...

Control of Hoxd gene transcription in the mammary bud by hijacking a preexisting regulatory landscape

Denis Duboule, Guillaume Andrey, Jozsef Zakany, Anamaria Necsulea, Leonardo Beccari, Edgardo Rodriguez Carballo, Virginie Marcet

Vertebrate Hox genes encode transcription factors operating during the development of multiple organs and structures. However, the evolutionary mechanism underlying this remarkable pleiotropy remains to be fully understood. Here, we show that Hoxd8 and Hox ...

Regulatory Switches Underlie Hoxd Gene Activation in Tetrapod Limbs

Guillaume Andrey

Accurate spatio-temporal control of Hox cluster genes expression is critical for the proper organization of body structures during vertebrate embryogenesis. In the limbs, Hoxd genes are critical in setting up the proximodistal and anteroposterior axes. Sev ...

A switch between topological domains underlies HoxD genes collinearity in mouse limbs

Didier Trono, Denis Duboule, Marion Leleu, Guillaume Andrey, Daniël Noordermeer

Hox genes are major determinants of the animal body plan, where they organize structures along both the trunk and appendicular axes. During mouse limb development, Hoxd genes are transcribed in two waves: early on, when the arm and forearm are specified, a ...
