NAD(+) repletion improves muscle function in muscular dystrophy and counters global PARylation

Johan Auwerx, Carlos Canto Alvarez, Laurent Mouchiroud, Dongryeol Ryu, Hongbo Zhang, Vincenzo Sorrentino, Keir Joe Menzies, Xu Wang, Karim Laurent Gariani

Neuromuscular diseases are often caused by inherited mutations that lead to progressive skeletal muscle weakness and degeneration. In diverse populations of normal healthy mice, we observed correlations between the abundance of mRNA transcripts related to ...

Tetracycline Antibiotics Impair Mitochondrial Function and Its Experimental Use Confounds Research

Johan Auwerx, Laurent Mouchiroud, Richardus Houtkooper

Tetracyclines, a class of antibiotics that target bacterial translation, are commonly used in research for inducible gene expression using Tet-ON/Tet-OFF systems. However, such tetracycline-inducible systems carry a risk. Given that mitochondria have a "ba ...

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

Martinus Adela Maria Gijs, Johan Auwerx, 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 ...

A method to identify and validate mitochondrial modulators using mammalian cells and the worm C-elegans

Johan Auwerx, Laurent Mouchiroud, Richardus Houtkooper, Norman Lionel Moullan, Pénélope Andreux, Adrienne Joëlle Laurence Mottis, Xu Wang, Virginija Jovaisaite

Mitochondria are semi-autonomous organelles regulated by a complex network of proteins that are vital for many cellular functions. Because mitochondrial modulators can impact many aspects of cellular homeostasis, their identification and validation has pro ...

Type 5 adenylyl cyclase disruption leads to enhanced exercise performance

Johan Auwerx, Laurent Mouchiroud, Richardus Houtkooper, Jie Zhang

The most important physiological mechanism mediating enhanced exercise performance is increased sympathetic, beta adrenergic receptor (beta-AR), and adenylyl cyclase (AC) activity. This is the first report of decreased AC activity mediating increased exerc ...

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

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

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 ' ...

Ncor1 is a physiological modulator of muscle mass and oxidative function

Johan Auwerx, Laurent Mouchiroud, Hiroyasu Yamamoto

The present invention provides methods of increasing muscle mass and muscle miochodrial oxidative metabolism. Additionally, the invention provides treating various disorders associated with mitochondrial dysfunction, including but not limited to metabolic ...

Tetracyclines Disturb Mitochondrial Function across Eukaryotic Models: A Call for Caution in Biomedical Research

Johan Auwerx, Bart Deplancke, Laurent Mouchiroud, Richardus Houtkooper, Evan Graehl Williams, Dongryeol Ryu, Norman Lionel Moullan, Adrienne Joëlle Laurence Mottis, Xu Wang, Michael Vincent Frochaux, Virginija Jovaisaite

In recent years, tetracyclines, such as doxycycline, have become broadly used to control gene expression by virtue of the Tet-on/Tet-off systems. However, the wide range of direct effects of tetracycline use has not been fully appreciated. We show here tha ...

Urolithin A induces mitophagy and prolongs lifespan in C. elegans and increases muscle function in rodents

Johan Auwerx, Maria del Carmen Sandi Perez, Patrick Aebischer, Laurent Mouchiroud, Evan Graehl Williams, Dongryeol Ryu, Pénélope Andreux, Elena Katsyuba, Pooja Jha, Damien Sébastien Huzard, Giuseppe Lo Sasso, Norman Lionel Moullan

The biological effects of urolithins remain poorly characterized, despite wide-spread human exposure via the dietary consumption of their metabolic precursors, the ellagitannins, which are found in the pomegranate fruit, as well as in nuts and berries. We ...

NCoR1 Is a Conserved Physiological Modulator of Muscle Mass and Oxidative Function

Johan Auwerx, Kristina Schoonjans, Carlos Canto Alvarez, Laurent Mouchiroud, Evan Graehl Williams, Hiroyasu Yamamoto

Transcriptional coregulators control the activity of many transcription factors and are thought to have wide-ranging effects on gene expression patterns. We show here that muscle-specific loss of nuclear receptor corepressor 1 (NCoR1) in mice leads to enha ...

Transcriptional Coregulators: Fine-Tuning Metabolism

Johan Auwerx, Laurent Mouchiroud

Metabolic homeostasis requires that cellular energy levels are adapted to environmental cues. This adaptation is largely regulated at the transcriptional level, through the interaction between transcription factors, coregulators, and the basal transcriptio ...
