The NAD-Booster Nicotinamide Riboside Potently Stimulates Hematopoiesis through Increased Mitochondrial Clearance

Johan Auwerx, Matthias Lütolf, Bart Deplancke, Carlos Canto Alvarez, Olaia Maria Naveiras Torres-Quiroga, George Coukos, Aurélien Laurent Jean-Charles Oggier, Dongryeol Ryu, Eija Riitta Pirinen, Loïc Tauzin

It has been recently shown that increased oxidative phosphorylation, as reflected by increased mitochondrial activity, together with impairment of the mitochondrial stress response, can severely compromise hematopoietic stem cell (HSC) regeneration. Here w ...

The NAD plus Salvage Pathway Potently Stimulates Hematopoiesis through Increased Mitochondrial Clearance and Asymmetric Division

Matthias Lütolf, Bart Deplancke, Carlos Canto Alvarez, Olaia Maria Naveiras Torres-Quiroga, Dongryeol Ryu, George Coukos, Aurélien Laurent Jean-Charles Oggier, Eija Riitta Pirinen, Vasco Ledebur de Antas de Campos, Loïc Tauzin

Pharmacological Inhibition of Poly(ADP-Ribose) Polymerases Improves Fitness and Mitochondrial Function in Skeletal Muscle

Johan Auwerx, Kristina Schoonjans, Carlos Canto Alvarez, Laurent Mouchiroud, Evan Graehl Williams, Hongbo Zhang, Norman Lionel Moullan, Eija Riitta Pirinen, Keir Joe Menzies, Laia Morato Fornaguera

We previously demonstrated that the deletion of the poly(ADP-ribose) polymerase (Parp)-1 gene in mice enhances oxidative metabolism, thereby protecting against diet-induced obesity. However, the therapeutic use of PARP inhibitors to enhance mitochondrial f ...

NAD(+)-Dependent Activation of Sirt1 Corrects the Phenotype in a Mouse Model of Mitochondrial Disease

Johan Auwerx, Eija Riitta Pirinen, Wei Li

Mitochondrial disorders are highly heterogeneous conditions characterized by defects of the mitochondrial respiratory chain. Pharmacological activation of mitochondrial biogenesis has been proposed as an effective means to correct the biochemical defects a ...

The activation of hepatic and muscle polyamine catabolism improves glucose homeostasis

Eija Riitta Pirinen

The mitochondrial biogenesis and energy expenditure regulator, PGC-1 alpha, has been previously reported to be induced in the white adipose tissue (WAT) and liver of mice overexpressing spermidine/spermine N (1)-acetyltransferase (SSAT). The activation of ...

In Vivo Modulation of Mitochondrial Activity Determines HSC Engraftment and Post-Transplant Survival in Mice

Matthias Lütolf, Johan Auwerx, Aline Roch, Mukul Girotra, Olaia Maria Naveiras Torres-Quiroga, Nicola Vannini, Richardus Houtkooper, Eija Riitta Pirinen, Vasco Ledebur de Antas de Campos

Mitochondrial sirtuins and metabolic homeostasis

Johan Auwerx, Eija Riitta Pirinen, Giuseppe Lo Sasso

The maintenance of metabolic homeostasis requires the well-orchestrated network of several pathways of glucose, lipid and amino acid metabolism. Mitochondria integrate these pathways and serve not only as the prime site of cellular energy harvesting but al ...
