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

Denis Duboule, Leonardo Beccari, Lucille Delisle, Jozsef Zakany

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 ...

Analysis of Polycerate Mutants Reveals the Evolutionary Co-option of HOXD1 for Horn Patterning in Bovidae

Denis Duboule, Aurélie Hintermann, Jozsef Zakany

In the course of evolution, pecorans (i.e., higher ruminants) developed a remarkable diversity of osseous cranial appendages, collectively referred to as "headgear," which likely share the same origin and genetic basis. However, the nature and function of ...

Control of growth and gut maturation by &ITHoxD&IT genes and the associated lncRNA &ITHaglr&IT

Denis Duboule, Fabrice Daniel Darbellay, Anamaria Necsulea, Jozsef Zakany

During embryonic development, Hox genes participate in the building of a functional digestive system in metazoans, and genetic conditions involving these genes lead to important, sometimes lethal,growth retardation. Recently, this phenotype was obtained af ...

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

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

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 ...

Uncoupling time and space in the collinear regulation of Hox genes

Denis Duboule, Jozsef Zakany

During development of the vertebrate body axis, Hox genes are transcribed sequentially, in both time and space, following their relative positions within their genomic clusters. Analyses of animal genomes support the idea that Hox gene clustering is essent ...

The role of Hox genes during vertebrate limb development

Denis Duboule, Jozsef Zakany

The potential role of Hox genes during vertebrate limb development was brought into focus by gene expression analyses in mice (P Dolle, JC Izpisua-Belmonte, H Falkenstein, A Renucci, D Duboule, Nature 1989, 342:767-772), at a time when limb growth and patt ...

Tinkering with constraints in the evolution of the vertebrate limb anterior-posterior polarity

Denis Duboule, Jozsef Zakany

Genes belonging to both HoxA and HoxD clusters are required for proper vertebrate limb development. Mice lacking all, or parts of, Hoxa and Hoxd functions in forelimbs, as well as mice with a gain of function of these genes in the early limb bud, have help ...
