Reorganisation of Hoxd regulatory landscapes during the evolution of a snake-like body plan

Denis Duboule

Within land vertebrate species, snakes display extreme variations in their body plan, characterized by the absence of limbs and an elongated morphology. Such a particular interpretation of the basic vertebrate body architecture has often been associated wi ...

Hotair Is Dispensible for Mouse Development

Denis Duboule, Anamaria Necsulea

Despite the crucial importance of Hox genes functions during animal development, the mechanisms that control their transcription in time and space are not yet fully understood. In this context, it was proposed that Hotair, a lncRNA transcribed from within ...

Structure, function and evolution of topologically associating domains (TADs) at HOX loci

Denis Duboule, Nicolas Lonfat

Hox genes encode transcription factors necessary for patterning the major developing anterior to posterior embryonic axis. In addition, during vertebrate evolution, various subsets of this gene family were co-opted along with the emergence of novel body st ...

Tetrapod axial evolution and developmental constraints; Empirical underpinning by a mouse model

Denis Duboule

The tetrapod vertebral column has become increasingly complex during evolution as an adaptation to a terrestrial life. At the same time, the evolution of the vertebral formula became subject to developmental constraints acting on the size of the cervical a ...

A large-scale, in vivo transcription factor screen defines bivalent chromatin as a key property of regulatory factors mediating Drosophila wing development

Bart Deplancke, Monica Albarca Aguilera

Transcription factors (TFs) are key regulators of cell fate. The estimated 755 genes that encode DNA binding domain-containing proteins comprise similar to 5% of all Drosophila genes. However, the majority has remained uncharacterized so far due to the lac ...

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 ...

Polycomb Recruitment and Targeting in Mammals

Patrick Schorderet

Polycomb- (PcG) and trithorax (trxG) group proteins are essential components in the regulation of multiple developmental regulators. In particular, during early stages, they act as chromatin modifiers in such a way as to set and maintain the transcriptiona ...

Role of a polymorphism in a Hox/Pax-responsive enhancer in the evolution of the vertebrate spine

Denis Duboule

Patterning of the vertebrate skeleton requires the coordinated activity of Hox genes. In particular, Hox10 proteins are essential to set the transition from thoracic to lumbar vertebrae because of their rib-repressing activity. In snakes, however, the thor ...

Bimodal control of Hoxd gene transcription in the spinal cord defines two regulatory subclusters

Denis Duboule

The importance of Hox genes in the specification of neuronal fates in the spinal cord has long been recognized. However, the transcriptional controls underlying their collinear expression domains remain largely unknown. Here we show in mice that the corres ...

The response of Desulfotomaculum reducens MI-1 to U(VI) exposure: a transcriptomic study

Rizlan Bernier-Latmani, Elena Cristina Dalla Vecchia

Desulfotomaculum reducens is the first Gram-positive sulfate- and metal-reducing bacterium for which the transcriptomic response to uranium exposure has been evaluated. The genes upregulated during fermentative growth in the presence of U(VI) as compared t ...
