NAD+ boosting reduces age-associated amyloidosis and restores mitochondrial homeostasis in muscle

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

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 ...

GCN5 maintains muscle integrity by acetylating YY1 to promote dystrophin expression

Johan Auwerx, Elena Katsyuba, Hongbo Zhang

Protein lysine acetylation is a post-translational modification that regulates protein structure and function. It is targeted to proteins by lysine acetyltransferases (KATs) or removed by lysine deacetylases. This work identifies a role for the KAT enzyme ...

The gut microbiota influences skeletal muscle mass and function in mice

Johan Auwerx, Hongbo Zhang, Walter Wahli

The functional interactions between the gut microbiota and the host are important for host physiology, homeostasis, and sustained health. We compared the skeletal muscle of germ-free mice that lacked a gut microbiota to the skeletal muscle of pathogen-free ...

Enhancing mitochondrial proteostasis reduces amyloid-beta proteotoxicity

Johan Auwerx, Davide D'Amico, Adrian Schmid, Mario Romani, Norman Lionel Moullan, Vincenzo Sorrentino, Hongbo Zhang, Francesca Potenza, Solene Rietsch

Alzheimer's disease is a common and devastating disease characterized by aggregation of the amyloid-beta peptide. However, we know relatively little about the underlying molecular mechanisms or how to treat patients with Alzheimer's disease. Here we provid ...

Agents and methods using thereof for the prevention and treatment of stem cell muscle disorders

Johan Auwerx, Dongryeol Ryu, Hongbo Zhang, Keir Joe Menzies

Abstract of the invention: The present invention relates to agents that induce mitochondrial unfolded protein response (UPR mt ) in muscle stem cells and prevents or reverse process of muscle stem cell senescence. Further, the invention relates to methods ...

Inhibiting poly ADP-ribosylation increases fatty acid oxidation and protects against fatty liver disease

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Dongryeol Ryu, Vera Monica Lemos Da Silva, Elena Katsyuba, Jun Yong Kim, Hongbo Zhang, Pooja Jha, Keir Joe Menzies

Background & Aims: To date, no pharmacological therapy has been approved for non-alcoholic fatty liver disease (NAFLD). The aim of the present study was to evaluate the therapeutic potential of poly ADP-ribose polymerase (PARP) inhibitors in mouse models o ...

Protein acetylation in metabolism - metabolites and cofactors

Johan Auwerx, Elena Katsyuba, Hongbo Zhang, Keir Joe Menzies

Reversible acetylation was initially described as an epigenetic mechanism regulating DNA accessibility. Since then, this process has emerged as a controller of histone and nonhistone acetylation that integrates key physiological processes such as metabolis ...
