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 ...
AMER ASSOC ADVANCEMENT SCIENCE2023Molecular Regulation of Muscle Stem Cell Fate during Skeletal Muscle Regeneration and Aging
Muscle stem cells (MuSCs) are the primary source of myogenic progenitors during muscle repair and are essential for the long-term regenerative capacity of skeletal muscle. Following myofiber injury, MuSCs transition from a quiescent to an activated state, ...
EPFL2022Urolithin A improves muscle function by inducing mitophagy in muscular dystrophy
Johan Auwerx, Pénélope Andreux, Davide D'Amico, Hao Li, 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 ...
AMER ASSOC ADVANCEMENT SCIENCE2021CO-REGULATION OF ENDOTHELIAL AND MYOGENIC CELL FATES THROUGH INTERCELLULAR CROSSTALK IN SKELETAL MUSCLE
Skeletal muscle is one of the most dynamic organs in the human body, which has a vigorous potential to regenerate and adapt to environmental changes. Depending on environments, skeletal muscle enables essential life activities to survive by controlling mov ...
EPFL2021Towards an in vitro cardiac model: 3D environment, co-culture, alignment, and mechanical stimulation impact on cell behavior
Our aim is to develop a 3D model unit of cardiac muscle: an in-vitro analog of the trabeculae carneae found in vivo. As a base hydrogel matrix for cardiomyocyte culture in 3D, we develop a blend of decellularized extracellular matrix (dECM) and fibrin. Thi ...
EPFL2021Metabolic rescue of muscle and muscle stem cells in muscle disease
Duchenne muscular dystrophy (DMD), caused by the mutation of dystrophin gene, is an X-linked disorder that affects 1 in 3500 males, leading to progressive muscle degeneration and eventually resulting in premature death. Increasing evidence indicates that D ...
EPFL2020Bioengineering the Human Muscle Stem-Cell Niche for Therapeutic Applications
In spite of decades of research, no feasible method for obtaining sufficient numbers of uncommitted muscle stem cells (MuSCs) for therapy of degenerative muscle diseases exists. One of the most fundamental problems associated with stem cell therapy of musc ...
EPFL2019Targeting mitochondrial bioenergetics and NAD+ metabolism during sarcopenia and regeneration of skeletal muscle
The progressive decline of muscle mass and function called sarcopenia is a multi-factorial process associated to frailty, disability, and low quality of life in the elderly. The co-factor nicotinamide adenine dinucleotide (NAD+) becomes a limiting factor i ...
EPFL2019Efficient transdifferentiation of human dermal fibroblasts into skeletal muscle
Skeletal muscle holds significant regenerative potential but is incapable of restoring tissue loss caused by severe injury, congenital defects or tumour ablation. Consequently, skeletal muscle models are being developed to study human pathophysiology and r ...
WILEY2018Mitochondria! function is impaired in the skeletal muscle of pre-frail elderly
Johan Auwerx, Pénélope Andreux
Aging is accompanied by a gradual decline in both muscle mass and strength over time, which can eventually lead to pathologies, such as frailty and sarcopenia. While these two conditions are well characterized, further investigation of the early biological ...
