MetabolomicsSMN deficiency perturbs monoamine neurotransmitter metabolism in spinal muscular atrophy

Beyond motor neuron degeneration, homozygous mutations in the survival motor neuron 1 (SMN1) gene cause multiorgan and metabolic defects in patients with spinal muscular atrophy (SMA). However, the precise biochemical features of these alterations and the age of onset in the brain and peripheral ...

MetabolomicsExercise-Associated Microbial Metabolites Prevent Skeletal Muscle Atrophy in Adult Mice
We previously reported that skeletal muscle adaptation to regular exercise requires a healthy gut microbiome, contributing to growing evidence that some exercise benefits are mediated by microbiome-derived metabolites. Here, to identify such exercise-associated microbial metabolites, we transfer cec...

ProteomicsGadd45a Promotes Skeletal Muscle Atrophy by Forming a Complex with the Protein Kinase MEKK4
Skeletal muscle atrophy is a serious and highly prevalent condition that remains poorly understood at the molecular level. Previous work found that skeletal muscle atrophy involves an increase in skeletal muscle Gadd45a expression, which is necessary and sufficient for skeletal muscle fiber atrophy...

Proteomics,MultiomicsProteomic and Transcriptomic Changes in Hibernating Grizzly Bears Reveal Metabolic and Signaling Pathways that Protect against Muscle Atrophy
Muscle atrophy is a physiological response to disuse and malnutrition, but hibernating bears are largely resistant to this phenomenon. Unlike other mammals, they efficiently reabsorb amino acids from urine, periodically activate muscle contraction, and their adipocytes differentially responds to ins...

TranscriptomicsDistinct Protein Degradation Induced by Different Disuse Models of Skeletal Muscle Atrophy
Skeletal muscle atrophy is a consequence of many diseases, environmental insults, inactivity, age and injury. Atrophy is characterized by active degradation and removal of contractile proteins and a reduction in fiber size. Animal models have been extensively used to identify pathways leading to a...

TranscriptomicsInvolvement of miRNAs in the Regulation of Muscle Wasting during Catabolic Conditions.
Loss of muscle proteins and the consequent weakness has important clinical consequences in diseases such as cancer, diabetes, chronic heart failure and in ageing. In fact, excessive proteolysis causes cachexia, accelerates disease progression and worsens life expectancy. Muscle atrophy involves a co...

TranscriptomicsMolecular and phenotypic characterization of a mouse model of oculopharyngeal muscular dystrophy reveals severe muscular atrophy restricted to fast glycolytic fibres
Oculopharyngeal muscular dystrophy (OPMD) is an adult-onset disorder characterized by ptosis, dysphagia and proximal limb weakness. Autosomal-dominant OPMD is caused by a short (GCG)8–13 expansions within the first exon of the poly(A)-binding protein nuclear 1 gene (PABPN1), leading to an expanded p...
