The mitochondrial calcium uniporter (MCU) activates mitochondrial respiration and enhances mobility by regulating mitochondrial redox state

Sonia Karaz, Vincenzo Sorrentino, Umberto De Marchi, Federico Sizzano

Regulation of mitochondrial redox balance is emerging as a key event for cell signaling in both physiological and pathological conditions. However, the link between the mitochondrial redox state and the modulation of these conditions remains poorly defined ...

Aging Disrupts Muscle Stem Cell Function by Impairing Matricellular WISP1 Secretion from Fibro-Adipogenic Progenitors

Patrick Descombes, Omid Mashinchian, Guillaume Jacot, Sylviane Métairon, Sonia Karaz, Laura Lukjanenko, Federico Sizzano, Sara Ancel

Research on age-related regenerative failure of skeletal muscle has extensively focused on the phenotypes of muscle stem cells (MuSCs). In contrast, the impact of aging on regulatory cells in the MuSC niche remains largely unexplored. Here, we demonstrate ...

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 ...

Nuclear Proteomics Uncovers Diurnal Regulatory Landscapes in Mouse Liver

Felix Naef, Loïc Dayon, Jingkui Wang, Frédéric Bruno Martin Gachon, Martin Kussmann, Daniel Alain Dominique Marie Mauvoisin, Florian Atger, Federico Sizzano

Diurnal oscillations of gene expression controlled by the circadian clock and its connected feeding rhythm enable organisms to coordinate their physiologies with daily environmental cycles. While available techniques yielded crucial insights into regulatio ...
