TGR5 Regulates Macrophage Inflammation in Nonalcoholic Steatohepatitis by Modulating NLRP3 Inflammasome Activation

Johan Auwerx, Kristina Schoonjans

Nonalcoholic steatohepatitis (NASH) is a chronic liver disease associated with dysregulation of liver metabolism and inflammation. G-protein coupled bile acid receptor 1 (TGR5) is a cell surface receptor that is involved in multiple metabolic pathways. How ...

NRK1 controls nicotinamide mononucleotide and nicotinamide riboside metabolism in mammalian cells

Johan Auwerx, Carlos Canto Alvarez, Joanna Ratajczak

NAD(+) is a vital redox cofactor and a substrate required for activity of various enzyme families, including sirtuins and poly(ADP-ribose) polymerases. Supplementation with NAD(+) precursors, such as nicotinamide mononucleotide (NMN) or nicotinamide ribosi ...

Genetic and dietary modulators of the inflammatory response in the gastrointestinal tract of the BXD mouse genetic reference population

Johan Auwerx, Kristina Schoonjans, Maroun Bou Sleiman, Alessia Perino, Xiaoxu Li, Jean-David Horacio Morel, Giorgia Benegiamo, Alexis Rapin, Alexis Maximilien Bachmann, Jonathan Allen Sulc, Johanne Gracia Anne Poisson

Inflammatory gut disorders, including inflammatory bowel disease (IBD), can be impacted by dietary, environmental, and genetic factors. While the incidence of IBD is increasing worldwide, we still lack a complete understanding of the gene-by-environment in ...

Machine learning-derived gut microbiome signature predicts fatty liver disease in the presence of insulin resistance

Johan Auwerx, Dongryeol Ryu

A simple predictive biomarker for fatty liver disease is required for individuals with insulin resistance. Here, we developed a supervised machine learning-based classifier for fatty liver disease using fecal 16S rDNA sequencing data. Based on the Kangbuk ...

The journey of resveratrol from yeast to human

Johan Auwerx

The natural polyphenolic compound resveratrol was first discovered in the 1940s. In the recent years, this compound received renewed interest as several findings implicated resveratrol as a potent SIRT1 activator capable of mimicking the effects of calorie ...

Systems Phytohormone Responses to Mitochondrial Proteotoxic Stress

Johan Auwerx, Xu Wang

Mitochondrial function is controlled by two separate genomes. This feature makes mitochondria prone to proteotoxic stress when a stoichiometric imbalance occurs in the protein complexes that perform oxidative phosphorylation, which consist of both nucleara ...

Cell Press2017

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 ...

The exercise-induced long noncoding RNA CYTOR promotes fast-twitch myogenesis in aging

Johan Auwerx, Giorgia Benegiamo, Tanes Imamura de Lima, Pirkka-Pekka Untamo Laurila, Martin Rainer Wohlwend, Mario Romani

Skeletal muscle displays remarkable plasticity upon exercise and is also one of the organs most affected by aging. Despite robust evidence that aging is associated with loss of fast-twitch (type II) muscle fibers, the underlying mechanisms remain to be elu ...

Growth differentiation factor 15 is a myomitokine governing systemic energy homeostasis

Johan Auwerx, Dongryeol Ryu

Reduced mitochondria! electron transport chain activity promotes longevity and improves energy homeostasis via cell-autonomous and non-autonomous factors in multiple model systems. This mitohormetic effect is thought to involve the mitochondrial unfolded p ...

Loss of hepatic Sirt7 accelerates diethylnitrosamine (DEN)-induced formation of hepatocellular carcinoma by impairing DNA damage repair

Johan Auwerx, Kristina Schoonjans

The mammalian sirtuin family (SIRT1-SIRT7) has shown diverse biological roles in the regulation and maintenance of genome stability under genotoxic stress. SIRT7, one of the least studied sirtuin, has been demonstrated to be a key factor for DNA damage res ...

Delivery of A Chemically Modified Noncoding RNA Domain Improves Dystrophic Myotube Function

Huyen Thuc Tran Luong, Johan Auwerx

Fast twitch muscle fibers are prone to degradation in skeletal muscle pathologies, such as sarcopenia and muscular dystrophies. We previously showed that the exercise-induced long noncoding RNA CYTOR promotes fast-twitch myogenesis. Here, we identify an in ...

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 ...

Genetic background and sex control the outcome of high-fat diet feeding in mice

Johan Auwerx

The sharp increase in obesity prevalence worldwide is mainly attributable to changes in physical activity and eating behavior but the metabolic and clinical impacts of these obesogenic conditions vary between sexes and genetic backgrounds. This warrants pe ...

The bile acid membrane receptor TGR5 as an emerging target in metabolism and inflammation

Johan Auwerx, Kristina Schoonjans, Thijs Pols, Lilia Noriega Lopez, Mitsunori Nomura

Bile acids (BAs) are amphipathic molecules that facilitate the uptake of lipids, and their levels fluctuate in the intestine as well as in the blood circulation depending on food intake. Besides their role in dietary lipid absorption, bile acids function a ...

Cyclo(His-Pro): A further step in the management of steatohepatitis

Johan Auwerx, Xiaoxu Li, Adrienne Joëlle Laurence Mottis, Alexis Rapin, Qi Wang, Alessia De Masi

Background & Aims: Non-alcoholic fatty liver disease (NAFLD) and steatohepatitis (NASH) have become the world's most common liver diseases, placing a growing strain on healthcare systems worldwide. Nonetheless, no effective pharmacological treatment has be ...

The mitochondrial unfolded protein response in mammalian physiology

Johan Auwerx, Adrienne Joëlle Laurence Mottis, Virginija Jovaisaite

Mitochondria, the main site of cellular energy harvesting, are derived from proteobacteria that evolved within our cells in endosymbiosis. Mitochondria retained vestiges of their proteobacterial genome, the circular mitochondrial DNA, which encodes 13 subu ...
