Fly Cell Atlas: A single-nucleus transcriptomic atlas of the adult fruit fly

Bart Deplancke, Vincent Roland Julien Gardeux, Fabrice David

For more than 100 years, the fruit fly Drosophila melanogaster has been one of the most studied model organisms. Here, we present a single-cell atlas of the adult fly, Tabula Drosophilae, that includes 580,000 nuclei from 15 individually dissected sexed ti ...

Ether lipids, sphingolipids and toxic 1-deoxyceramides as hallmarks for lean and obese type 2 diabetic patients

Fabrice David

Aim: The worldwide increase in obesity and type 2 diabetes (T2D) represents a major health challenge. Chronically altered lipids induced by obesity further promote the development of T2D, and the accumulation of toxic lipid metabolites in serum and periphe ...

Systematic analysis of differential rhythmic liver gene expression mediated by the circadian clock and feeding rhythms

Felix Naef, Cédric Gobet, Fabrice David, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger, Nicholas Edward Phillips

The circadian clock and feeding rhythms are both important regulators of rhythmic gene expression in the liver. To further dissect the respective contributions of feeding and the clock, we analyzed differential rhythmicity of liver tissue samples across se ...

Spatial tissue profiling by imaging-free molecular tomography

Gioele La Manno, Fabrice David

Several techniques are currently being developed for spatially resolved omics profiling, but each new method requires the setup of specific detection strategies or specialized instrumentation. Here we describe an imaging-free framework to localize high-thr ...

ASAP 2020 update: an open, scalable and interactive web-based portal for (single-cell) omics analyses

Bart Deplancke, Vincent Roland Julien Gardeux, Fabrice David, Maria Litovchenko

Single-cell omics enables researchers to dissect biological systems at a resolution that was unthinkable just 10 years ago. However, this analytical revolution also triggered new demands in 'big data' management, forcing researchers to stay up to speed wit ...

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

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

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 ...

Differential regulation of RNA polymerase III genes during liver regeneration

Olivier Martin, Bart Deplancke, Felix Naef, Jacques Rougemont, Marion Leleu, Nicolas Jean Philippe Guex, Fabrice David, Kyle Gustafson, Dominic Villeneuve, Cristian Carmeli

Mouse liver regeneration after partial hepatectomy involves cells in the remaining tissue synchronously entering the cell division cycle. We have used this system and H3K4me3, Pol II and Pol III profiling to characterize adaptations in Pol III transcriptio ...

Systematic lipidomic analysis of yeast protein kinase and phosphatase mutants reveals novel insights into regulation of lipid homeostasis

Fabrice David, Howard Riezman, Manuele Piccolis

The regulatory pathways required to maintain eukaryotic lipid homeostasis are largely unknown. We developed a systematic approach to uncover new players in the regulation of lipid homeostasis. Through an unbiased mass spectrometry-based lipidomic screening ...
