Background: Global analyses of gene expression during development reveal specific transcription patterns associated with the emergence of various cell types, tissues, and organs. These heterogeneous patterns are instrumental to ensure the proper formation ...

Collinear regulation of Hox genes in space and time has been an outstanding question ever since the initial work of Ed Lewis in 1978. Here we discuss recent advances in our understanding of this phenomenon in relation to novel concepts associated with larg ...

Background The spatial organization of the mammalian genome relies upon the formation of chromatin domains of various scales. At the level of gene regulation in cis, collections of enhancer sequences define large regulatory landscapes that usually match wi ...

Hox genes control many aspects of embryonic development in metazoans. Previous analyses of this gene family revealed a surprising diversity in terms of gene number and organization between various animal species. In vertebrates, Hox genes are grouped into ...

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 ...

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 ...

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 ...

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, ...

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 ...

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 ...

SHFM3 is a limb malformation characterized by the absence of central digits. It has been shown that this condition is associated with tandem duplications of about 500 kb at 10q24. The Dactylaplasia mice display equivalent limb defects and the two correspon ...

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 ...

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 ...

During vertebrate development, the temporal control of Hox gene transcriptional activation follows the genomic order of the genes within the Hox clusters. Although it is recognized that this "Hox clock" serves to coordinate body patterning, the underlying ...

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 ...

Genetic studies have revealed that the antagonistic interplay between PcG and TrxG/MLL complexes is essential for the proper maintenance of vertebrate Hox gene expression in time and space. Hox genes must be silenced in totipotent embryonic stem cells and, ...

Transcription of HoxD cluster genes in limbs is coordinated by two topologically associating domains (TADs), neighboring the cluster and containing various enhancers. Here, we use a combination of microscopy approaches and chromosome conformation capture t ...

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 ...

Although all bilaterian animals have a related set of Hox genes, the genomic organization of this gene complement comes in different flavors. In some unrelated species, Hox genes are clustered; in others, they are not. This indicates that the bilaterian an ...

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 ...
