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 ...

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 ...

Microtubule-mediated GLUT4 trafficking is disrupted in insulin-resistant skeletal muscle

Martinus Gijs, Raphaël Etienne Jean Trouillon, Martin Rainer Wohlwend

Microtubules serve as tracks for long-range intracellular trafficking of glucose transporter 4 (GLUT4), but the role of this process in skeletal muscle and insulin resistance is unclear. Here, we used fixed and live-cell imaging to study microtubule-based ...

Products and methods for promoting myogenesis

Johan Auwerx, Martin Rainer Wohlwend

The present invention relates generally to the field of long non-coding RNAs and transcription factors and modulation of their expression for use in medicine and agriculture, such as the treatment and prevention of diseases associated with muscle atrophy a ...

Sphingolipids accumulate in aged muscle, and their reduction counteracts sarcopenia

Johan Auwerx, Davide D'Amico, Tanes Imamura de Lima, Qi Wang, Sébastien Robert Victor Herzig, Maroun Bou Sleiman, Martin Rainer Wohlwend, Peiling Luan, Pirkka-Pekka Untamo Laurila, Barbara Moreira Crisol

Age-related muscle dysfunction and sarcopenia are major causes of physical incapacitation in older adults and currently lack viable treatment strategies. Here we find that sphingolipids accumulate in mouse skeletal muscle upon aging and that both genetic a ...

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 ...

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 exercise-induced long noncoding RNA CYTOR promotes fast-twitch myogenesis in aging

Johan Auwerx, Mario Romani, Tanes Imamura de Lima, Martin Rainer Wohlwend, Pirkka-Pekka Untamo Laurila

Skeletal muscle displays remarkable plasticity upon exercise and is also one of the organs most affected by aging. Despite robust evidence that aging is associated with loss of fast-twitch (type II) muscle fibers, the underlying mechanisms remain to be elu ...

Urolithin A improves muscle function by inducing mitophagy in muscular dystrophy

Johan Auwerx, Pénélope Andreux, Davide D'Amico, Hao Li, Tanes Imamura de Lima, Martin Rainer Wohlwend, Peiling Luan, Pirkka-Pekka Untamo Laurila

Duchenne muscular dystrophy (DMD) is the most common muscular dystrophy, and despite advances in genetic and pharmacological disease-modifying treatments, its management remains a major challenge. Mitochondrial dysfunction contributes to DMD, yet the mecha ...
