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

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 ...

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 ...

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, Jéromine Imbach

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 ...

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 ...

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

Johan Auwerx, Hao Li

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 ...

Computing correspondences in geometric data sets

Mark Pauly, Hao Li

Shape registration and, more generally speaking, computing correspondence across shapes are fundamental problems in computer graphics and vision. Problems from this area show up in many diff erent variants such as scan registration, deformable shape matchi ...

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 ...

Modern techniques and applications for real-time non-rigid registration

Sofien Bouaziz, Mark Pauly, Andrea Tagliasacchi, Hao Li

Registration algorithms are an essential component of many computer graphics and computer vision systems. With recent technological advances in RGBD sensors (color plus depth), an active area of research is in techniques combining color, geometry, and lear ...

Realtime Performance-Based Facial Animation

Sofien Bouaziz, Mark Pauly, Hao Li

This paper presents a system for performance-based character animation that enables any user to control the facial expressions of a digital avatar in realtime. The user is recorded in a natural environment using a non-intrusive, commercially available 3D s ...

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, Francesca Pontanari, 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 ...

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 ...

Cortical ensembles orchestrate social competition through hypothalamic outputs

Sébastien Benjamin Hausmann, 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 ...

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, Yan Liu, Jia 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 ...

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 ...

Cross-species functional modules link proteostasis to human normal aging

Johan Auwerx, 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 ...

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 ...

Dynamic hair capture

Mark Pauly, Hao Li

The realistic reconstruction of hair motion is challenging because of hair’s complex occlusion, lack of a well-defined surface, and non-Lambertian material. We present a system for passive capture of dynamic hair performances using a set of high-speed vide ...
