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, Hao Li, Mario Romani, Dohyun Park, Pirkka-Pekka Untamo Laurila, Changmyung Oh, Martin Rainer Wohlwend, Jean-David Horacio Morel, Xiaoxu Li, Ludger Jan Elzuë Goeminne, Tanes Imamura de Lima, Sandra Rodriguez Lopez, Barbara Moreira Crisol

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

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

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

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 ...

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

Kristina Schoonjans, Johan Auwerx, Alexis Maximilien Bachmann, Maroun Bou Sleiman, Alessia Perino, Amir Banaei Esfahani, Karim Laurent Gariani, Giacomo Vincenzo Giorgio Von Alvensleben, Hao Li, Qingyao Huang, Laura Alejandra Velazquez Villegas, Yu Sun, Xiaoxu Li, 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, Peiling Luan, Hao Li, Davide D'Amico, Pirkka-Pekka Untamo Laurila, Martin Rainer Wohlwend, Tanes Imamura de Lima

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

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 ...

PHD3 Loss Promotes Exercise Capacity and Fat Oxidation in Skeletal Muscle

Daniel Garcia, Johan Auwerx, Hao Li

Rapid alterations in cellular metabolism allow tissues to maintain homeostasis during changes in energy availability. The central metabolic regulator acetyl-CoA carboxylase 2 (ACC2) is robustly phosphorylated during cellular energy stress by AMP-activated ...

Cross-species functional modules link proteostasis to human normal aging

Johan Auwerx, Andrea Komljenovic, Hao Li, Vincenzo Sorrentino

The evolutionarily conserved nature of the few well-known anti-aging interventions that affect lifespan, such as caloric restriction, suggests that aging-related research in model organisms is directly relevant to human aging. Since human lifespan is a com ...

The RNA-Binding Protein PUM2 Impairs Mitochondrial Dynamics and Mitophagy During Aging

Bernard Schneider, Graham Knott, Kristina Schoonjans, Johan Auwerx, Adrienne Joëlle Laurence Mottis, Vera Monica Lemos Da Silva, Hao Li, Vincenzo Sorrentino, Davide D'Amico, Mario Romani, Francesca Potenza

Little information is available about how post-transcriptional mechanisms regulate the aging process. Here, we show that the RNA-binding protein Pumilio2 (PUM2), which is a translation repressor, is induced upon aging and acts as a negative regulator of li ...

Systems genetics approaches to probe gene function

Hao Li

Genes are the functional units of heredity. However, the functions of many genes remain unknown, which impedes the understanding of the underlying mechanism of complex traits and diseases. Systems genetics approaches try to understand the complexity underl ...

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

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

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 ...

Wireless Neurosensor for Full-Spectrum Electrophysiology Recordings during Free Behavior

Yao Lu, Grégoire Courtine, David Allenson Borton, Jean François Pierre Laurens, Hao Li

Brain recordings in large animal models and humans typically rely on a tethered connection, which has restricted the spectrum of accessible experimental and clinical applications. To overcome this limitation, we have engineered a compact, lightweight, high ...

Factored Facade Acquisition using Symmetric Line Arrangements

Duygu Ceylan, Mark Pauly, Hao Li

We introduce a novel framework for image-based 3D reconstruction of urban buildings based on symmetry priors. Starting from image-level edges, we generate a sparse and approximate set of consistent 3D lines. These lines are then used to simultaneously dete ...
