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

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

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 ...

A novel two-compartment barrier model for investigating nanoparticle transport in fish intestinal epithelial cells

Kristin Schirmer, Laura Sigg

We introduce a novel in vitro rainbow trout intestinal barrier model and demonstrate its suitability for investigating nanoparticle transport across the intestinal epithelium. Rainbow trout (Oncorhynchus mykiss) intestinal cells (RTgutGC) were grown as mon ...

Functional intestinal bile acid 7-alpha-dehydroxylation by Clostridium scindens associated with protection from C. difficile infection in a gnotobiotic mouse model

Rizlan Bernier-Latmani, Laure Menin, Lyne Desharnais

Bile acids, important mediators of lipid absorption, also act as hormone-like regulators and as antimicrobial molecules. In all these functions their potency is modulated by a variety of chemical modifications catalyzed by bacteria of the healthy gut micro ...

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

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

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 ...

Caged luciferin probes for the bioluminescence imaging of nitroreductase and hydrogen sulfide in living animals

Anzhelika Vorobyeva

Molecular imaging advances our understanding of cellular and molecular functions within complex biological systems. The development of novel imaging probes that can be applied to answer fundamental biological questions, diagnose and monitor disease progres ...

Wnt Ligands Secreted by Subepithelial Mesenchymal Cells Are Essential for the Survival of Intestinal Stem Cells and Gut Homeostasis

Michel Aguet, Andreas Eduard Moor

Targeting of Wnt signaling represents a promising anti-cancer therapy. However, the consequences of systemically attenuating the Wnt pathway in an adult organism are unknown. Here, we globally prevent Wnt secretion by genetically ablating Wntless. We find ...

Intimate gut interactions: helminths and the microbiota

Nicola Harris

Changing exposure to intestinal helminths, or alterations in our intestinal microbiome, have been independently proposed to underlie the increasing incidence of chronic inflammatory diseases including allergy, autoimmunity and inflammatory bowel disease (I ...

Polycomb Complex PRC1 Preserves Intestinal Stem Cell Identity by Sustaining Wnt/beta-Catenin Transcriptional Activity

Paloma Ordonez Moran

Polycomb repressive complexes (PRCs) are among the most important gatekeepers of establishing and maintaining cell identity in metazoans. PRC1, which plays a dominant role in this context, executes its functions via multiple subcomplexes, which all contrib ...

IMMUNOLOGY Chronic effects of acute infections

Nicola Harris

Acute infection of mice with an intestinal pathogen leads to long-lasting inflammation that is maintained by intestinal microorganisms. This observation reveals a path by which infection history can affect long-term immune function. ...

Farnesoid X receptor inhibits glucagon-like peptide-1 production by enteroendocrine L cells

Kristina Schoonjans, Alessia Perino, Yasmine Sebti

Bile acids are signalling molecules, which activate the transmembrane receptor TGR5 and the nuclear receptor FXR. BA sequestrants (BAS) complex bile acids in the intestinal lumen and decrease intestinal FXR activity. The BAS-BA complex also induces glucago ...
