Skeletal muscle as an experimental model of choice to study tissue aging and rejuvenation. [PDF]

, 2020
Skeletal muscle is among the most age-sensitive tissues in mammal organisms. Significant changes in its resident stem cells (i.e., satellite cells, SCs), differentiated cells (i.e., myofibers), and extracellular matrix cause a decline in tissue ...

Vitamin D, a modulator of musculoskeletal health in chronic kidney disease [PDF]

, 2017
The spectrum of activity of vitamin D goes beyond calcium and bone homeostasis, and growing evidence suggests that vitamin D contributes to maintain musculoskeletal health in healthy subjects as well as in patients with chronic kidney disease (CKD ...

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 ...

Hematopoietic (stem) cells—The elixir of life?

FEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

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 ...

The role and implications of mammalian cellular circadian entrainment

FEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Complex coordination of cell plasticity by a PGC-1α-controlled transcriptional network in skeletal muscle [PDF]

, 2015
Skeletal muscle cells exhibit an enormous plastic capacity in order to adapt to external stimuli. Even though our overall understanding of the molecular mechanisms that underlie phenotypic changes in skeletal muscle cells remains poor, several factors ...

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.
