Physical inactivity induces insulin resistance in plantaris muscle through protein tyrosine phosphatase 1B activation in mice

Frontiers in Physiology, 2023
Inactivity causes insulin resistance in skeletal muscle and exacerbates various lifestyle-related diseases. We previously found that 24-h hindlimb cast immobilization (HCI) of the predominantly slow-twitch soleus muscle increased intramyocellular ...

Comparative analysis of the transcriptomes of EDL, psoas, and soleus muscles from mice

BMC Genomics, 2020
Background Individual skeletal muscles have evolved to perform specific tasks based on their molecular composition. In general, muscle fibers are characterized as either fast-twitch or slow-twitch based on their myosin heavy chain isoform profiles.

Histochemical Differentiation of Fibers in the Rat Slow and Fast Twitch Muscles.

The Japanese Journal of Physiology, 1991
Wistar male rats were sacrificed at 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, and 21 days, and at 5 and 10 weeks of age. The histochemical differentiation of slow twitch soleus and fast twitch plantaris muscle fibers was examined from the enzyme activities of adenosine triphosphatase (slow- or fast-contracting), succinate dehydrogenase (high- or low-oxidative)

Prediction of muscle fiber composition using multiple repetition testing

Biology of Sport, 2020
Direct determination of muscle fiber composition is invasive and expensive, with indirect methods also requiring specialist resources and expertise. Performing resistance exercises at 80% 1RM is suggested as a means of indirectly estimating muscle fiber ...

Charge Movement in a Fast Twitch Skeletal Muscle from Rat

Biophysical Journal, 1983
Voltage-dependent charge movement in the rat omohyoid muscle was investigated using the three microelectrode voltage clamp technique. The charge that moved during a depolarization from the holding potential (-90 mV) to the test potential, V, increased with increasing V, saturating around 0 mV. The charge vs.

A chronic high‐fat diet does not exacerbate muscle atrophy in fast‐twitch skeletal muscle of aged mice

Experimental Physiology, 2023
Obesity and ageing reduce muscle mass and lead to deficits in muscle maintenance, but it is not known whether obesity accelerates muscle wasting additively in the setting of ageing.

Changes in transcriptional activity of chronically stimulated fast twitch muscle [PDF]

FEBS Letters, 1983
mRNAs extracted from rabbit soleus, normal and 28‐day, indirectly stimulated tibialis anterior muscles were translated in an in vitro system. Analysis for translation products by 2‐dimensional electrophoresis showed fast myosin light chains in tibialis anterior, and slow myosin light chains in soleus muscle. The stoichiometry of the in vitro translated

Neuromuscular junction pathology is correlated with differential motor unit vulnerability in spinal and bulbar muscular atrophy

Acta Neuropathologica Communications, 2022
Spinal and bulbar muscular atrophy (SBMA) is an X-linked, neuromuscular neurodegenerative disease for which there is no cure. The disease is characterized by a selective decrease in fast-muscle power (e.g., tongue pressure, grip strength) accompanied by ...

Need for speed: Human fast-twitch mitochondria favor power over efficiency

Molecular Metabolism
Objective: Human skeletal muscle consists of a mixture of slow- and fast-twitch fibers with distinct capacities for contraction mechanics, fermentation, and oxidative phosphorylation.

Light‐Assisted 3D Printing Techniques and Photocrosslinking Strategies: Recent Advances in Musculoskeletal Tissue Engineering

Advanced Engineering Materials, EarlyView.
In this review, the current state of light‐assisted 3D printing as it pertains to engineering musculoskeletal tissues including bone, cartilage, skeletal muscle, tendon, and ligaments is summarized. Common printing techniques, photoreactive materials, and study design choices are compiled and reviewed.
