A lysosomal surveillance response to stress extends healthspan

Johan Auwerx, Yang Li, Wen Gao, Xiaoxu Li, Amélia Lalou, Tanes Imamura de Lima, Qi Wang, Jia Liu

Lysosomes are cytoplasmic organelles central for the degradation of macromolecules to maintain cellular homoeostasis and health. However, how lysosomal activity can be boosted to counteract ageing and ageing-related diseases remains elusive. Here we reveal ...

Systems genetics of metabolic health in the BXD mouse genetic reference population

Johan Auwerx, Maroun Bou Sleiman, Wen Gao, Jean-David Horacio Morel, Xiaoxu Li, Alessia De Masi, Amélia Lalou, Jia Liu

Susceptibility to metabolic syndrome (MetS) is dependent on genetics, environment, and gene-by-environment interactions, rendering the study of underlying mechanisms challenging. The majority of experiments in model organisms do not incorporate genetic var ...

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

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

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 ...

Drug Screening in C. elegans to identify new pharmacological mitochondrial stress inducers

Amélia Lalou

Mitochondria are essential organelles participating in numerous cellular functions, including energy harvesting, regulation of homeostasis and apoptosis. Changes in mitochondrial number, morphology, and function not only impact cellular metabolism but also ...

Inhibition of CERS1 in skeletal muscle exacerbates age-related muscle dysfunction

Olivier Burri, Johan Auwerx, Giacomo Vincenzo Giorgio Von Alvensleben, Pirkka-Pekka Untamo Laurila, Martin Rainer Wohlwend, Xiaoxu Li, Ludger Jan Elzuë Goeminne, Amélia Lalou, Tanes Imamura de Lima, Barbara Moreira Crisol, Renata Mangione

Age-related muscle wasting and dysfunction render the elderly population vulnerable and incapacitated, while underlying mechanisms are poorly understood. Here, we implicate the CERS1 enzyme of the de novo sphingolipid synthesis pathway in the pathogenesis ...

Article Multi-omics analysis identifies essential regulators of mitochondrial stress response in two wild-type C. elegans strains

Johan Auwerx, Maroun Bou Sleiman, Yang Li, Gaby El Alam, Wen Gao, Amélia Lalou

The mitochondrial unfolded protein response (UPRmt) is a promising pharmacological target for aging and age-related diseases. However, the integrative analysis of the impact of UPRmt activation on different signaling layers in animals with different geneti ...

V-ATPase/TORC1-mediated ATFS-1 translation directs mitochondrial UPR activation in C. elegans

Felix Naef, Kristina Schoonjans, Johan Auwerx, Hao Li, Yang Li, Wen Gao, Xiaoxu Li, Amélia Lalou, Nagammal Neelagandan, Jia Liu, Yuan Liu

To adapt mitochondrial function to the ever-changing intra- and extracellular environment, multiple mitochondrial stress response (MSR) pathways, including the mitochondrial unfolded protein response (UPRmt), have evolved. However, how the mitochondrial st ...
