Bioelectrical impedance vectors analysis (BIVA) in older adults according to level of physical activity and muscle strength: a comparison of classic and specific approaches

Frontiers in Aging
IndroductionBioelectrical Impedance Analysis (BIA) is a widely used method to assess body composition. Traditional BIA models use predictive equations without considering individual characteristics such as age, sex, and activity level.

Normal inflammation and regeneration of muscle following injury require osteopontin from both muscle and non-muscle cells

Skeletal Muscle, 2019
Background Osteopontin is secreted by skeletal muscle myoblasts and macrophages, and its expression is upregulated in muscle following injury. Osteopontin is present in many different structural forms, which vary in their expression patterns and effects ...

A reference single-cell transcriptomic atlas of human skeletal muscle tissue reveals bifurcated muscle stem cell populations

Skeletal Muscle, 2020
Single-cell RNA-sequencing (scRNA-seq) facilitates the unbiased reconstruction of multicellular tissue systems in health and disease. Here, we present a curated scRNA-seq dataset of human muscle samples from 10 adult donors with diverse anatomical ...

Membrane glucocorticoid receptors are localised in the extracellular matrix and signal through the MAPK pathway in mammalian skeletal muscle fibres [PDF]

, 2015
A number of studies have previously proposed the existence of glucocorticoid receptors on the plasma membrane of many cell types including skeletal muscle fibres.

Ergothioneine supplementation improves pup phenotype and survival in a murine model of spinal muscular atrophy

FEBS Letters, EarlyView.
Spinal muscular atrophy (SMA) is a genetic disease affecting motor neurons. Individuals with SMA experience mitochondrial dysfunction and oxidative stress. The aim of the study was to investigate the effect of an antioxidant and neuroprotective substance, ergothioneine (ERGO), on an SMNΔ7 mouse model of SMA.

Diversification of the muscle proteome through alternative splicing

Skeletal Muscle, 2018
Background Skeletal muscles express a highly specialized proteome that allows the metabolism of energy sources to mediate myofiber contraction. This muscle-specific proteome is partially derived through the muscle-specific transcription of a subset of ...

Oxytocin is an age-specific circulating hormone that is necessary for muscle maintenance and regeneration. [PDF]

, 2014
The regenerative capacity of skeletal muscle declines with age. Previous studies suggest that this process can be reversed by exposure to young circulation; however, systemic age-specific factors responsible for this phenomenon are largely unknown.

Imeglimin attenuates liver fibrosis by inhibiting vesicular ATP release from hepatic stellate cells

FEBS Letters, EarlyView.
Imeglimin, at clinically relevant concentrations, inhibits vesicular ATP accumulation and release from hepatic stellate cells, thereby attenuating purinergic signaling and reducing fibrogenic activation. This mechanism reveals a newly identified antifibrotic action of imeglimin beyond glycemic control.

Nicotinamide phosphoribosyltransferase (Nampt) in Lateral Hypothalamus Maintains Skeletal Muscle Functions Through Lactate‐Mediated Calcium Signalling in Male Mice

Journal of Cachexia, Sarcopenia and Muscle
Background Sarcopenia has become an urgent socioeconomic problem in rapidly aging societies. The pathogenesis of age‐associated sarcopenia is not fully understood and no effective therapeutic strategies have been developed to date.

SMCHD1 regulates a limited set of gene clusters on autosomal chromosomes

Skeletal Muscle, 2017
Background Facioscapulohumeral muscular dystrophy (FSHD) is in most cases caused by a contraction of the D4Z4 macrosatellite repeat on chromosome 4 (FSHD1) or by mutations in the SMCHD1 or DNMT3B gene (FSHD2).
