Impact of genome architecture on the functional activation and repression of Hox regulatory landscapes

Denis Duboule, Lucille Delisle, Edgardo Rodriguez Carballo, Nayuta Yakushiji

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 ...

The human genome encodes some 350 Kruppel-associated box (KRAB) domain-containing zinc-finger proteins (KZFPs), the products of a rapidly evolving gene family that has been traced back to early tetrapods(1,2). The function of most KZFPs is unknown, but a f ...

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 ...

Intra- and interspecific social challenges modulate the levels of an androgen precursor in a seasonally territorial tropical damselfish

Katarina Damjanovic

Studies on different vertebrate groups have provided evidence that androgen levels in males increase after competitive social interactions during the breeding season, as postulated by the Challenge Hypothesis. However, social modulation of androgen levels ...

The evolution of tetrapod limbs from fish fins enabled the conquest of land by vertebrates and thus represents a key step in evolution. Despite the use of comparative gene expression analyses, critical aspects of this transformation remain controversial, i ...

Evolving Hox Activity Profiles Govern Diversity in Locomotor Systems

Denis Duboule

The emergence of limb-driven locomotor behaviors was a key event in the evolution of vertebrates and fostered the transition from aquatic to terrestrial life. We show that the generation of limb-projecting lateral motor column (LMC) neurons in mice relies ...

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 function for all posterior Hoxd genes during digit development?

Denis Duboule, Saskia Joëlle Delpretti Anex, Jozsef Zakany

Background: Four posterior Hoxd genes, from Hoxd13 to Hoxd10, are collectively regulated during the development of tetrapod digits. Besides the well-documented role of Hoxd13, the function of the neighboring genes has been difficult to evaluate due to the ...

ABSTRACT: BACKGROUND: The development of vertebrate limbs has been a traditional system to study fundamental processes at work during ontogenesis, such as the establishment of spatial cellular coordinates, the effect of diffusible morphogenetic molecules o ...

CCCTC-binding factor (CTCF) is a nuclear zinc-finger protein that displays insulating activity in a variety of biological assays. For example, CTCF-binding sites have been suggested to isolate Hox gene clusters from neighboring transcriptional interference ...
