Extensive tissue-specific expression variation and novel regulators underlying circadian behavior

Matteo Dal Peraro, Bart Deplancke, Vincent Roland Julien Gardeux, Julie Marie Russeil, Virginie Sandra Braman, Antonio Carlos Alves Meireles Filho, Maria Litovchenko, Michael Vincent Frochaux, Alessio Prunotto, Brian Dennis Hollis

Natural genetic variation affects circadian rhythms across the evolutionary tree, but the underlying molecular mechanisms are poorly understood. We investigated population-level, molecular circadian clock variation by generating >700 tissue-specific transc ...

cis-regulatory variation modulates susceptibility to enteric infection in the Drosophila genetic reference panel

Bart Deplancke, Vincent Roland Julien Gardeux, Maroun Bou Sleiman, Virginie Sandra Braman, Riccardo Dainese, Maria Litovchenko, Michael Vincent Frochaux, Dani Osman, Brian Dennis Hollis, Tommaso Andreani

Background: Resistance to enteric pathogens is a complex trait at the crossroads of multiple biological processes. We have previously shown in the Drosophila Genetic Reference Panel (DGRP) that resistance to infection is highly heritable, but our understan ...

Enteric infection induces Lark-mediated intron retention at the 5 ' end of Drosophila genes

Bart Deplancke, Maroun Bou Sleiman, Michael Vincent Frochaux, Dani Osman, Tommaso Andreani

Background RNA splicing is a key post-transcriptional mechanism that generates protein diversity and contributes to the fine-tuning of gene expression, which may facilitate adaptation to environmental challenges. Here, we employ a systems approach to study ...

Inter-embryo gene expression variability recapitulates the hourglass pattern of evo-devo

Bart Deplancke, Vincent Roland Julien Gardeux, Michael Vincent Frochaux

Background The evolution of embryological development has long been characterized by deep conservation. In animal development, the phylotypic stage in mid-embryogenesis is more conserved than either early or late stages among species within the same phylum ...

Multilevel regulation of the glass locus during Drosophila eye development

Bart Deplancke, Michael Vincent Frochaux, Abhishek Kumar Mishra

Development of eye tissue is initiated by a conserved set of transcription factors termed retinal determination network (RDN). In the fruit fly Drosophila melanogaster, the zinc-finger transcription factor Glass acts directly downstream of the RDN to contr ...

Elucidating regulatory mechanisms shaping the transcriptome and proteome of the gut immune response in Drosophila melanogaster

Michael Vincent Frochaux

Work on Drosophila melanogaster paved the way to our current understanding of modern genetics. Since then, this model organism has contributed greatly to various fields such as neurobiology, development, and immunology. The discovery and analysis of the va ...

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

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

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 ...

Tetracyclines Disturb Mitochondrial Function across Eukaryotic Models: A Call for Caution in Biomedical Research

Johan Auwerx, Bart Deplancke, Richardus Houtkooper, Laurent Mouchiroud, Dongryeol Ryu, Xu Wang, Evan Graehl Williams, Adrienne Joëlle Laurence Mottis, Virginija Jovaisaite, Norman Lionel Moullan

In recent years, tetracyclines, such as doxycycline, have become broadly used to control gene expression by virtue of the Tet-on/Tet-off systems. However, the wide range of direct effects of tetracycline use has not been fully appreciated. We show here tha ...

An evolutionarily conserved role for the aryl hydrocarbon receptor in the regulation of movement

Johan Auwerx, Bart Deplancke, Laurent Mouchiroud, Pénélope Andreux, Evan Graehl Williams, Michael Vincent Frochaux

The BXD genetic reference population is a recombinant inbred panel descended from crosses between the C57BL/6 (B6) and DBA/2 (D2) strains of mice, which segregate for about 5 million sequence variants. Recently, some of these variants have been established ...
