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

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

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 ...

Phosphorylation of the nuclear receptor co-repressor 1 by protein kinase B (PKB/Akt) switches its co-repressor targets in the liver

Kristina Schoonjans, Johan Auwerx, Dongryeol Ryu, Adriano Maida, Xu Wang

The nuclear receptor corepressor 1 (NCoR1) is a transcriptional co-regulator that has wide-ranging effects on gene expression patterns. In the liver, NCoR1 represses lipid synthesis in the fasting state, whereas it inhibits the activation of PPARα upon fee ...

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

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

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 ...

Hypothalamic S1P/S1PR1 axis controls energy homeostasis

Dongryeol Ryu

Sphingosine 1-phosphate receptor 1 (S1PR1) is a G-protein-coupled receptor for sphingosine-1-phosphate (S1P) that has a role in many physiological and pathophysiological processes. Here we show that the S1P/S1PR1 signalling pathway in hypothalamic neurons ...

A SIRT7-Dependent Acetylation Switch of GABPβ1 Controls Mitochondrial Function

Matthias Alexander Sokrates Stein, Kristina Schoonjans, Johan Auwerx, Dongryeol Ryu, Giuseppe Lo Sasso, Hongbo Zhang, Alessia Perino

Mitochondrial activity is controlled by proteins encoded by both nuclear and mitochondrial DNA. Here, we identify Sirt7 as a crucial regulator of mitochondrial homeostasis. Sirt7 deficiency in mice induces multisystemic mitochondrial dysfunction, which is ...

Loss of Sirt1 function improves intestinal anti-bacterial defense and protects from colitis-induced colorectal cancer

Elena Katsyuba, Kristina Schoonjans, Johan Auwerx, Dongryeol Ryu, Laurent Mouchiroud, Giuseppe Lo Sasso, Alessandra Piersigilli

Dysfunction of Paneth and goblet cells in the intestine contributes to inflammatory bowel disease (IBD) and colitis-associated colorectal cancer (CAC). Here, we report a role for the NAD+-dependent histone deacetylase SIRT1 in the control of anti-bacterial ...

SUMOylation-Dependent LRH-1/PROX1 Interaction Promotes Atherosclerosis by Decreasing Hepatic Reverse Cholesterol Transport

Matthias Alexander Sokrates Stein, Kristina Schoonjans, Chikage Mataki, Dongryeol Ryu, Maaike Hélène Oosterveer, Pan Xu, Keir Joe Menzies, Alessia Perino, Xu Wang, Vera Monica Lemos Da Silva

Reverse cholesterol transport (RCT) is an antiatherogenic process in which excessive cholesterol from peripheral tissues is transported to the liver and finally excreted from the body via the bile. The nuclear receptor liver receptor homolog 1 (LRH-1) driv ...

Mitonuclear protein imbalance as a conserved longevity mechanism

Graham Knott, Elena Katsyuba, Johan Auwerx, Richardus Houtkooper, Norman Lionel Moullan, Dongryeol Ryu, Laurent Mouchiroud

Longevity is regulated by a network of closely linked metabolic systems. We used a combination of mouse population genetics and RNA interference in Caenorhabditis elegans to identify mitochondrial ribosomal protein S5 (Mrps5) and other mitochondrial riboso ...

Calorie Restriction-like Effects of 30 Days of Resveratrol Supplementation on Energy Metabolism and Metabolic Profile in Obese Humans

Johan Auwerx, Richardus Houtkooper, Dongryeol Ryu

Resveratrol is a natural compound that affects energy metabolism and mitochondrial function and serves as a calorie restriction mimetic, at least in animal models of obesity. Here, we treated 11 healthy, obese men with placebo and 150 mg/day resveratrol (r ...
