GPS2-mediated regulation of the adipocyte secretome modulates adipose tissue remodeling at the onset of diet-induced obesity

Objective: Dysfunctional, unhealthy expansion of white adipose tissue due to excess dietary intake is a process at the root of obesity and Type 2 Diabetes development. The objective of this study is to contribute to a better understanding of the underlying ...

Inhibiting de novo ceramide synthesis restores mitochondrial and protein homeostasis in muscle aging

Johan Auwerx, Xiaoxu Li, Mario Romani, Tanes Imamura de Lima, Sandra Rodriguez Lopez, Hao Li, Martin Rainer Wohlwend, Pirkka-Pekka Untamo Laurila, Ludger Jan Elzuë Goeminne, Dohyun Park

Disruption of mitochondrial function and protein homeostasis plays a central role in aging. However, how these processes interact and what governs their failure in aging remain poorly understood. Here, we showed that cer- amide biosynthesis controls the de ...

Cortical ensembles orchestrate social competition through hypothalamic outputs

Hao Li

Most social species self-organize into dominance hierarchies(1,2), which decreases aggression and conserves energy(3,4), but it is not clear how individuals know their social rank. We have only begun to learn how the brain represents social rank(5-9) and g ...

The Slc25a47 locus is a novel determinant of hepatic mitochondrial function implicated in liver fibrosis

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Xiaoxu Li, Vera Monica Lemos Da Silva, Hadrien Charles Edouard Demagny, Hao Li, Yu Sun, Nadia Bresciani

Background & Aims: Transporters of the SLC25 mitochondrial carrier superfamily bridge cytoplasmic and mitochondrial metabolism by channeling metabolites across mitochondrial membranes and are pivotal for metabolic homeostasis. Despite their physiological r ...

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

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

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 ...

Integrative systems analysis identifies genetic and dietary modulators of bile acid homeostasis

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Xiaoxu Li, Giacomo Vincenzo Giorgio Von Alvensleben, Hao Li, Maroun Bou Sleiman, Karim Laurent Gariani, Laura Alejandra Velazquez Villegas, Ludger Jan Elzuë Goeminne

Bile acids (BAs) are complex and incompletely understood enterohepatic-derived hormones that control whole-body metabolism. Here, we profiled postprandial BAs in the liver, feces, and plasma of 360 chowor high-fat-diet-fed BXD male mice and demonstrated th ...

Urolithin A improves muscle function by inducing mitophagy in muscular dystrophy

Johan Auwerx, Pénélope Andreux, Davide D'Amico, Hao Li, Tanes Imamura de Lima, Martin Rainer Wohlwend, Peiling Luan, Pirkka-Pekka Untamo Laurila

Duchenne muscular dystrophy (DMD) is the most common muscular dystrophy, and despite advances in genetic and pharmacological disease-modifying treatments, its management remains a major challenge. Mitochondrial dysfunction contributes to DMD, yet the mecha ...

NAD+ boosting reduces age-associated amyloidosis and restores mitochondrial homeostasis in muscle

Johan Auwerx, Mario Romani, Tanes Imamura de Lima, Hao Li, Vincenzo Sorrentino, Hongbo Zhang, Changmyung Oh

Aging is characterized by loss of proteostasis and mitochondrial homeostasis. Here, we provide bioinformatic evidence of dysregulation of mitochondrial and proteostasis pathways in muscle aging and diseases. Moreover, we show accumulation of amyloid-like d ...

Mouse Systems Genetics as a Prelude to Precision Medicine

Johan Auwerx, Hao Li

Mouse models have been instrumental in understanding human disease biology and proposing possible new treatments. The precise control of the environment and genetic composition of mice allows more rigorous observations, but limits the generalizability and ...
