A multiscale study of the role of dynamin in the regulation of glucose uptake

Johan Auwerx, Martinus Gijs, Kristina Schoonjans, Laurent Mouchiroud, Raphaël Etienne Jean Trouillon, Keir Joe Menzies, Maria Cristina Letizia

Glucose uptake in muscle cells in response to insulin is a fundamental mechanism for metabolism. The inability of cells to mobilize the specific glucose transporter GLUT4 is believed to be at least partially accountable for diseases, like diabetes, where c ...

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 ...

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

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

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 ...

NAD+ repletion improves mitochondrial and stem cell function and enhances life span in mice

Johan Auwerx, Kristina Schoonjans, Matthias Lütolf, Davide D'Amico, Dongryeol Ryu, Xu Wang, Hongbo Zhang, Peiling Luan, Keir Joe Menzies, Karim Laurent Gariani

Adult stem cells (SCs) are essential for tissue maintenance and regeneration yet are susceptible to senescence during aging. We demonstrate the importance of the amount of the oxidized form of cellular nicotinamide adenine dinucleotide (NAD(+)) and its imp ...

NAD(+) Metabolism and the Control of Energy Homeostasis: A Balancing Act between Mitochondria and the Nucleus

Johan Auwerx, Carlos Canto Alvarez, Keir Joe Menzies

NAD(+) has emerged as a vital cofactor that can rewire metabolism, activate sirtuins, and maintain mitochondrial fitness through mechanisms such as the mitochondrial unfolded protein response. This improved understanding of NAD(+) metabolism revived intere ...
