Single-nucleus RNA-seq and FISH identify coordinated transcriptional activity in mammalian myofibers

Nature Communications, 2020
Whether skeletal muscle fibre gene expression is coordinated as a whole in different nuclei in the fibre is unclear. Here, the authors use single nucleus RNAseq and ATACseq to show the transcriptome heterogeneity of muscle nuclei in the adult mouse fibre,

Respiratory muscle fibres: specialisation and plasticity [PDF]

Thorax, 2004
Skeletal muscles are composed of fibres of different types, each type being identified by the isoform of myosin heavy chain which is expressed as slow 1, fast 2A, fast 2X, and fast 2B. Slow fibres are resistant to fatigue due to their highly oxidative metabolism whereas 2X and 2B fibres are easily fatiguable and fast 2A fibres exhibit intermediate ...

Constitutive expression of Yes-associated protein (Yap) in adult skeletal muscle fibres induces muscle atrophy and myopathy.

PLoS ONE, 2013
The aim of this study was to investigate the function of the Hippo pathway member Yes-associated protein (Yap, gene name Yap1) in skeletal muscle fibres in vivo.

Dietary ractopamine supplementation of pregnant sows: what are the impacts on the neonate?

Animal, 2020
The use of additives such as ractopamine (Rac) in pregnant sows during early-mid pregnancy is an alternative to increase foetal and progeny growth and development.

The association between muscle architecture and muscle spindle abundance

Scientific Reports, 2023
Across the human body, skeletal muscles have a broad range of biomechanical roles that employ complex proprioceptive control strategies to successfully execute a desired movement.

Metabolic heterogeneity of muscle fibres [PDF]

Journal of Experimental Biology, 1985
ABSTRACTMammalian skeletal muscle is an extremely heterogeneous tissue. Its diversity results from a spectrum of fibres which are metabolically suited to a wide range of functional demands. As judged from enzyme activity analyses of single fibres, the metabolic properties of fibres belonging to the same motor unit are similar or identical. It is likely,

The influence of training status, age, and muscle fiber type on cycling efficiency and endurance performance. [PDF]

, 2013
The purpose of this study was to assess the influence of age, training status, and muscle fiber-type distribution on cycling efficiency. Forty men were recruited into one of four groups: young and old trained cyclists, and young and old untrained ...

Capillary rarefaction during bed rest is proportionally less than fibre atrophy and loss of oxidative capacity

Journal of Cachexia, Sarcopenia and Muscle, 2022
Background Muscle disuse from bed rest or spaceflight results in losses in muscle mass, strength and oxidative capacity. Capillary rarefaction may contribute to muscle atrophy and the reduction in oxidative capacity during bed rest.

Jitter in the muscle fibre. [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 1990
Direct stimulation of muscle fibres with a regular 10 Hz rate, three computer generated random rhythms and a sequence of voluntary discharges was used to quantify the interdischarge interval (IDI) dependent jitter due to velocity recovery function (VRF).

Development temperature has persistent effects on muscle growth responses in gilthead sea bream [PDF]

, 2012
Initially we characterised growth responses to altered nutritional input at the transcriptional and tissue levels in the fast skeletal muscle of juvenile gilthead sea bream.
