High-content phenotypic analysis of a C. elegans recombinant inbred population identifies genetic and molecular regulators of lifespan

Johan Auwerx, Laurent Mouchiroud, Xiaoxu Li, Maroun Bou Sleiman, Elena Katsyuba, Wen Gao, Yang Li, Amélia Lalou, Gaby El Alam, Jean-David Horacio Morel

Lifespan is influenced by complex interactions between genetic and environmental factors. Studying those factors in model organisms of a single genetic background limits their translational value for humans. Here, we mapped lifespan determinants in 85 C. e ...

TBK1 phosphorylates mutant Huntingtin and suppresses its aggregation and toxicity in Huntington's disease models

Johan Auwerx, Hilal Lashuel, Laurent Mouchiroud, Anass Chiki, Lara Petricca, Ramanath Narayana Hegde

Phosphorylation of the N‐terminal domain of the huntingtin (HTT ) protein has emerged as an important regulator of its localization, structure, aggregation, clearance and toxicity. However, validation of the effect of bona fide phosphorylation in vivo and ...

Automated Platform for Long-Term Culture and High-Content Phenotyping of Single C. elegans Worms

Johan Auwerx, Martinus Gijs, Matteo Cornaglia, Laurent Mouchiroud, Rongrong Xiang, Elena Katsyuba, Hüseyin Baris Atakan

The nematode Caenorhabditis elegans is a suitable model organism in drug screening. Traditionally worms are grown on agar plates, posing many challenges for long-term culture and phenotyping of animals under identical conditions. Microfluidics allows for ' ...

Automated High-Content Phenotyping Of The Nematode C. Elegans At Single Animal Resolution With A Microfluidic Platform

Johan Auwerx, Martinus Gijs, Matteo Cornaglia, Laurent Mouchiroud, Rongrong Xiang, Hüseyin Baris Atakan

In this work, we present a novel microfluidic approach to culture the nematode C. elegans from the onset of embryogenesis to the adult stage at single animal resolution. Our device allows high-throughput experimentation, high-resolution imaging, thereby pr ...

Automated high-content phenotyping from the first larval stage till the onset of adulthood of the nematode Caenorhabditis elegans

Johan Auwerx, Martinus Gijs, Matteo Cornaglia, Laurent Mouchiroud, Hüseyin Baris Atakan

The nematode Caenorhabditis elegans is increasingly used as a model for human biology. However, in vivo culturing platforms for C. elegans allowing high-content phenotyping during their life cycle in an automated fashion are lacking so far. Here, a multipl ...

Multimodal imaging and high-throughput image-processing for drug screening on living organisms on-chip

Michaël Unser, Johan Auwerx, Martinus Gijs, Matteo Cornaglia, Laurent Mouchiroud, Daniel Migliozzi, Virginie Sophie Uhlmann

A major step for the validation of medical drugs is the screening on whole organisms, which gives the systemic information that is missing when using cellular models. Caenorhabditis elegans is a soil worm that catches the interest of researchers who study ...
