Bile Acids Signal via TGR5 to Activate Intestinal Stem Cells and Epithelial Regeneration

Kristina Schoonjans, Maroun Bou Sleiman, Alessia Perino, Ece Yildiz, Giovanni Sorrentino, Gaby El Alam

BACKGROUND & AIMS: Renewal and patterning of the intestinal epithelium is coordinated by intestinal stem cells (ISCs); dietary and metabolic factors provide signals to the niche that control ISC activity. Bile acids (BAs), metabolites in the gut, signal nu ...

Identifying gene function and module connections by the integration of multispecies expression compendia

Stephan Morgenthaler, Elena Katsyuba, Kristina Schoonjans, Johan Auwerx, Fabrice David, Maroun Bou Sleiman, Daria Rukina, Andrea Komljenovic, Hao Li, Qingyao Huang, Yang Li, Changmyung Oh, Wen Gao

The functions of many eukaryotic genes are still poorly understood. Here, we developed and validated a new method, termed GeneBridge, which is based on two linked approaches to impute gene function and bridge genes with biological processes. First, Gene-Mo ...

Commensal Gut Bacteria Buffer the Impact of Host Genetic Variants on Drosophila Developmental Traits under Nutritional Stress

Michael Vincent Frochaux, Bart Deplancke, Maroun Bou Sleiman, Virginie Sandra Braman, Maria Litovchenko

Eukaryotic genomes encode several buffering mechanisms that robustly maintain invariant phenotypic outcome despite fluctuating environmental conditions. Here we show that the Drosophila gut-associated commensals, represented by a single facultative symbion ...

The chromatin remodeling factor ISW-1 integrates organismal responses against nuclear and mitochondrial stress

Johan Auwerx, Maroun Bou Sleiman

Age-associated changes in chromatin structure have a major impact on organismal longevity. Despite being a central part of the ageing process, the organismal responses to the changes in chromatin organization remain unclear. Here we show that moderate dist ...

The effects of mitochondrial- and histone stress on the C. elegans transcriptome

Johan Auwerx, Maroun Bou Sleiman, Pedro Moral Quiros

The aim of this study was to explore whether mitochondrial- and histone stress cause any common changes in global gene expression. For this experiment, we performed RNA sequencing from control RNAi, cco-1 RNAi (mitochondrial stress) and his-3 RNAi (histone ...

The Drosophila gut response to infection : a systems approach

Maroun Bou Sleiman

Genetic, physiological, and biochemical studies have successfully ascribed functions to genes in diverse processes. However, the majority of our knowledge in biology is qualitative in nature and is usually based on classical screens, where large effects on ...

Genetic, molecular and physiological basis of variation in Drosophila gut immunocompetence

Bruno Lemaitre, Bart Deplancke, Andreas Massouras, Dani Osman, Maroun Bou Sleiman

Gut immunocompetence involves immune, stress and regenerative processes. To investigate the determinants underlying inter-individual variation in gut immunocompetence, we perform enteric infection of 140 Drosophila lines with the entomopathogenic bacterium ...

The Black cells phenotype is caused by a point mutation in the Drosophila pro-phenoloxidase 1 gene that triggers melanization and hematopoietic defects

Bruno Lemaitre, Olivier Binggeli, Maroun Bou Sleiman, Lise Bertin

Melanization contributes to arthropod-specific innate immunity through deposition of melanin at wound sites or around parasites, with concomitant release of microbicidal reactive oxygen species. Melanization requires sequential activation of proteolytic en ...

Transforming Growth Factor beta/Activin Signaling Functions as a Sugar-Sensing Feedback Loop to Regulate Digestive Enzyme Expression

Bruno Lemaitre, Wen Bin Chng, Maroun Bou Sleiman

Organisms need to assess their nutritional state and adapt their digestive capacity to the demands for various nutrients. Modulation of digestive enzyme production represents a rational step to regulate nutriment uptake. However, the role of digestion in n ...

Randomized codon mutagenesis reveals that the HIV Rev arginine-rich motif is robust to substitutions and that double substitution of two critical residues alters specificity

Maroun Bou Sleiman

The binding of the arginine-rich motif (ARM) of HIV Rev protein to its high-affinity site in stem IIB in the Rev response element (RRE) initiates assembly of a ribonucleoprotein complex that mediates the export of essential, incompletely spliced viral tran ...
