Induction of mitochondrial recycling reverts age-associated decline of the hematopoietic and immune systems

Johan Auwerx, Olaia Maria Naveiras Torres-Quiroga, Frédérica Schyrr, Charles Christopher Bataclan

Aging compromises hematopoietic and immune system functions, making older adults especially susceptible to hematopoietic failure, infections and tumor development, and thus representing an important medical target for a broad range of diseases. During agin ...

Genetic and dietary modulators of the inflammatory response in the gastrointestinal tract of the BXD mouse genetic reference population

Alexis Rapin, Kristina Schoonjans, Johan Auwerx, Alexis Maximilien Bachmann, Maroun Bou Sleiman, Alessia Perino, Jean-David Horacio Morel, Xiaoxu Li

Inflammatory gut disorders, including inflammatory bowel disease (IBD), can be impacted by dietary, environmental, and genetic factors. While the incidence of IBD is increasing worldwide, we still lack a complete understanding of the gene-by-environment in ...

Lysosomes mediate the mitochondrial UPR via mTORC1-dependent ATF4 phosphorylation

Johan Auwerx, Adrienne Joëlle Laurence Mottis, Yang Li, Wen Gao, Xiaoxu Li, Qi Wang

Lysosomes are central platforms for not only the degradation of macromolecules but also the integration of multiple signaling pathways. However, whether and how lysosomes mediate the mitochondrial stress response (MSR) remain largely unknown. Here, we demo ...

Mitochondria: A "pacemaker"for species-specific development

Johan Auwerx, Jia Liu

We highlight papers by Diaz-Cuadros et al.(1) and Iwata et al.(2) that demonstrate the role of mitochondrial metabolism in setting developmental pace through their control over cellular bioenergetics and redox homeostasis in mice and humans. ...

Hepatic lipid overload triggers biliary epithelial cell activation via E2Fs

Kristina Schoonjans, Johan Auwerx, Alessia Perino, Ece Yildiz, Giovanni Sorrentino, Gaby El Alam, Antoine Jalil

During severe or chronic hepatic injury, biliary epithelial cells (BECs) undergo rapid activation into proliferating progenitors, a crucial step required to establish a regenerative process known as ductular reaction (DR). While DR is a hallmark of chronic ...

Sex- and age-dependent genetics of longevity in a heterogeneous mouse population

Johan Auwerx, Maroun Bou Sleiman, Giacomo Vincenzo Giorgio Von Alvensleben, Hao Li, Wen Gao

Tetracycline-induced mitohormesis mediates disease tolerance against influenza

Elena Katsyuba, Alexis Rapin, Johan Auwerx, Nicola Harris, Adrienne Joëlle Laurence Mottis, Davide D'Amico, Yang Li, Gaby El Alam

Mitohormesis defines the increase in fitness mediated by adaptive responses to mild mitochondrial stress. Tetracyclines inhibit not only bacterial but also mitochondrial translation, thus imposing a low level of mitochondrial stress on eukaryotic cells. We ...

Urolithin A improves muscle strength, exercise performance, and biomarkers of mitochondrial health in a randomized trial in middle-aged adults

Patrick Aebischer, Johan Auwerx, Pénélope Andreux

Targeting mitophagy to activate the recycling of faulty mitochondria during aging is a strategy to mitigate muscle decline. We present results from a randomized, placebo-controlled trial in middle-aged adults where we administer a postbiotic compound Uroli ...

The Slc25a47 locus is a novel determinant of hepatic mitochondrial function implicated in liver fibrosis

Kristina Schoonjans, Johan Auwerx, Alessia Perino, Vera Monica Lemos Da Silva, Hao Li, Hadrien Charles Edouard Demagny, Nadia Bresciani, Yu Sun, Xiaoxu Li

Background & Aims: Transporters of the SLC25 mitochondrial carrier superfamily bridge cytoplasmic and mitochondrial metabolism by channeling metabolites across mitochondrial membranes and are pivotal for metabolic homeostasis. Despite their physiological r ...

Article Multi-omics analysis identifies essential regulators of mitochondrial stress response in two wild-type C. elegans strains

Johan Auwerx, Maroun Bou Sleiman, Yang Li, Gaby El Alam, Wen Gao, Amélia Lalou

The mitochondrial unfolded protein response (UPRmt) is a promising pharmacological target for aging and age-related diseases. However, the integrative analysis of the impact of UPRmt activation on different signaling layers in animals with different geneti ...

Machine learning-derived gut microbiome signature predicts fatty liver disease in the presence of insulin resistance

Johan Auwerx, Dongryeol Ryu

A simple predictive biomarker for fatty liver disease is required for individuals with insulin resistance. Here, we developed a supervised machine learning-based classifier for fatty liver disease using fecal 16S rDNA sequencing data. Based on the Kangbuk ...

V-ATPase/TORC1-mediated ATFS-1 translation directs mitochondrial UPR activation in C. elegans

Felix Naef, Kristina Schoonjans, Johan Auwerx, Hao Li, Yang Li, Wen Gao, Xiaoxu Li, Amélia Lalou, Nagammal Neelagandan, Jia Liu, Yuan Liu

To adapt mitochondrial function to the ever-changing intra- and extracellular environment, multiple mitochondrial stress response (MSR) pathways, including the mitochondrial unfolded protein response (UPRmt), have evolved. However, how the mitochondrial st ...

Non-genomic activation of the AKT-mTOR pathway by the mitochondrial stress response in thyroid cancer

Kristina Schoonjans, Johan Auwerx, Dongryeol Ryu

Cancer progression is associated with metabolic reprogramming and causes significant intracellular stress; however, the mechanisms that link cellular stress and growth signalling are not fully understood. Here, we identified a mechanism that couples the mi ...

Sirtuin 7 Deficiency Reduces Inflammation and Tubular Damage Induced by an Episode of Acute Kidney Injury

Johan Auwerx

Acute kidney injury (AKI) is a public health problem worldwide. Sirtuins are a family of seven NAD+-dependent deacylases, Overexpression of Sirtuin 1, 3, and 5 protect against AKI. However, the role of Sirtuin 7 (Sirt7) in AKI is not known. Here, we analyz ...
