Failure of metabolic checkpoint control during late-stage granulopoiesis drives neutropenia in reticular dysgenesis

Cellular metabolism is highly dynamic during hematopoiesis, yet the regulatory networks that maintain metabolic homeostasis during differentiation are incompletely understood. Herein, we have studied the grave immunodeficiency syndrome reticular dysgenesis ...

Inhibition of CERS1 in skeletal muscle exacerbates age-related muscle dysfunction

Johan Auwerx, Olivier Burri, Xiaoxu Li, Tanes Imamura de Lima, Giacomo Vincenzo Giorgio Von Alvensleben, Martin Rainer Wohlwend, Pirkka-Pekka Untamo Laurila, Ludger Jan Elzuë Goeminne, Amélia Lalou, Barbara Moreira Crisol

Age-related muscle wasting and dysfunction render the elderly population vulnerable and incapacitated, while underlying mechanisms are poorly understood. Here, we implicate the CERS1 enzyme of the de novo sphingolipid synthesis pathway in the pathogenesis ...

The genetic background shapes the susceptibility to mitochondrial dysfunction and NASH progression

Johan Auwerx, Sandra Rodriguez Lopez, Giacomo Vincenzo Giorgio Von Alvensleben, Maroun Bou Sleiman, Ludger Jan Elzuë Goeminne, Alexis Maximilien Bachmann, Jean-David Horacio Morel

Mice from different genetic backgrounds have widely diverse responses to the same metabolic challenges. Only PWK/PhJ mice show significant mitochondrial dysfunction and progression to fibrotic NASH that resembles human NASH. The PWK/PhJ strain is a novel N ...

Gene network based analysis identifies a coexpression module involved in regulating plasma lipids with high-fat diet response

Johan Auwerx, Ludger Jan Elzuë Goeminne

Plasma lipids are modulated by gene variants and many environmental factors, including diet-associated weight gain. However, understanding how these factors jointly interact to influence molecular networks that regulate plasma lipid levels is limited. Here ...

Inhibiting de novo ceramide synthesis restores mitochondrial and protein homeostasis in muscle aging

Johan Auwerx, Xiaoxu Li, Mario Romani, Tanes Imamura de Lima, Sandra Rodriguez Lopez, Hao Li, Martin Rainer Wohlwend, Pirkka-Pekka Untamo Laurila, Ludger Jan Elzuë Goeminne, Dohyun Park

Disruption of mitochondrial function and protein homeostasis plays a central role in aging. However, how these processes interact and what governs their failure in aging remain poorly understood. Here, we showed that cer- amide biosynthesis controls the de ...

Integrative systems analysis identifies genetic and dietary modulators of bile acid homeostasis

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Xiaoxu Li, Giacomo Vincenzo Giorgio Von Alvensleben, Hao Li, Maroun Bou Sleiman, Karim Laurent Gariani, Laura Alejandra Velazquez Villegas, Ludger Jan Elzuë Goeminne

Bile acids (BAs) are complex and incompletely understood enterohepatic-derived hormones that control whole-body metabolism. Here, we profiled postprandial BAs in the liver, feces, and plasma of 360 chowor high-fat-diet-fed BXD male mice and demonstrated th ...

Inhibition of sphingolipid de novo synthesis counteracts muscular dystrophy

Johan Auwerx, Tanes Imamura de Lima, Martin Rainer Wohlwend, Peiling Luan, Pirkka-Pekka Untamo Laurila, Ludger Jan Elzuë Goeminne

Duchenne muscular dystrophy (DMD), the most common muscular dystrophy, is a severe muscle disorder, causing muscle weakness, loss of independence, and premature death. Here, we establish the link between sphingolipids and muscular dystrophy. Transcripts of ...

Evidence for a neuromuscular circuit involving hypothalamic interleukin-6 in the control of skeletal muscle metabolism

Vera Monica Lemos Da Silva, Ludger Jan Elzuë Goeminne, Barbara Moreira Crisol, Eduardo Rochete Ropelle

Hypothalamic interleukin-6 (IL6) exerts a broad metabolic control. Here, we demonstrated that IL6 activates the ERK1/2 pathway in the ventromedial hypothalamus (VMH), stimulating AMPK/ACC signaling and fatty acid oxidation in mouse skeletal muscle. Bioinfo ...

COX7A2L genetic variants determine cardiorespiratory fitness in mice and human

Johan Auwerx, Sandra Rodriguez Lopez, Maroun Bou Sleiman, Pooja Jha, Martin Rainer Wohlwend, Pirkka-Pekka Untamo Laurila, Ludger Jan Elzuë Goeminne

Benegiamo et al. identify genetic variants of the mitochondrial supercomplex assembly factor COX7A2L in the skeletal muscle of mice and humans that promote cardiorespiratory fitness. ...

The mouse metallomic landscape of aging and metabolism

Johan Auwerx, Richardus Houtkooper, Evan Graehl Williams, Pooja Jha, Ludger Jan Elzuë Goeminne, Jean-David Horacio Morel

The metallome is crucial for normal cell functioning but remains largely overlooked in mammals. Here the authors analyze the metallome and copper and zinc isotope compositions in aging mice and show networks of interactions that are organ-specific, age-dep ...
