A role for HOX13 proteins in the regulatory switch between TADs at the HoxD locus

Denis Duboule, Anamaria Necsulea, Nicolas Lonfat

During vertebrate limb development, Hoxd genes are regulated following a bimodal strategy involving two topologically associating domains (TADs) located on either side of the gene cluster. These regulatory landscapes alternatively control different subsets ...

Topological Domains, Metagenes, and the Emergence of Pleiotropic Regulations at Hox Loci

Denis Duboule, Fabrice Daniel Darbellay

Hox gene clusters of jaw vertebrates display a tight genomic organization, which has no equivalent in any other bilateria genomes sequenced thus far. It was previously argued that such a topological consolidation toward a condensed, metagenic structure was ...

Genome-Wide Ultrabithorax Binding Analysis Reveals Highly Targeted Genomic Loci at Developmental Regulators and a Potential Connection to Polycomb-Mediated Regulation

Antonio Carlos Alves Meireles Filho

Hox homeodomain transcription factors are key regulators of animal development. They specify the identity of segments along the anterior-posterior body axis in metazoans by controlling the expression of diverse downstream targets, including transcription f ...

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 ...

Abrogation of HMX1 Function Causes Rare Oculoauricular Syndrome Associated With Congenital Cataract, Anterior Segment Dysgenesis, and Retinal Dystrophy

PURPOSE. To define the phenotypic manifestation, confirm the genetic basis, and delineate the pathogenic mechanisms underlying an oculoauricular syndrome (OAS). METHODS. Two individuals from a consanguineous family underwent comprehensive clinical phenotyp ...

Visualizing the HoxD Gene Cluster at the Nanoscale Level

Denis Duboule, Suliana Manley, Aleksandr Benke

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 ...

An ancestral regulatory mechanism underlies Hoxd gene expression in both developing genitals and digits

Nicolas Lonfat

Coordinated expression of HoxD cluster genes is crucial for the emergence and patterning of both developing digits and external genitalia. As a shared evolutionary origin has been proposed for these secondary structures, which may have accompanied the tran ...

Comparing genomes with rearrangements and segmental duplications

Bernard Moret, Mingfu Shao

Motivation: Large-scale evolutionary events such as genomic rearrange. ments and segmental duplications form an important part of the evolution of genomes and are widely studied from both biological and computational perspectives. A basic computational pro ...
