Skeletal muscle and fiber type-specific intramyocellular lipid accumulation in obese mice

Biomolecules & Biomedicine, 2021
In obesity, accumulation of lipid droplets in skeletal muscle fibers and a shift towards fast muscle fiber types can both contribute to insulin resistance.

“Biqi” Bayberry Extract Promotes Skeletal Muscle Fiber Type Remodeling by Increasing Fast Myofiber Formation via the Akt/FoxO1 Pathway in Mice

Foods, 2023
Bayberry is known to be a rich source of natural flavonoids and has been reported to have various health-promoting abilities. However, its function on regulating skeletal muscle fiber type remains unclear.

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 ...

Cycling Cross-Bridges Contribute to Thin Filament Activation in Human Slow-Twitch Fibers

Frontiers in Physiology, 2020
It has been shown that not only calcium but also strong binding myosin heads contribute to thin filament activation in isometrically contracting animal fast-twitch and cardiac muscle preparations. This behavior has not been studied in human muscle fibers

Expression of aquaporin-4 in fast-twitch fibers of mammalian skeletal muscle. [PDF]

Journal of Clinical Investigation, 1998
In this study we analyzed the expression of aquaporin-4 (AQP4) in mammalian skeletal muscle. Immunohistochemical experiments revealed that affinity-purified AQP4 antibodies stained selectively the sarcolemma of fast-twitch fibers. By immunogold electron microscopy, little or no intracellular labeling was detected.

Size and Proportions of Slow-Twitch and Fast-Twitch Muscle Fibers in Human Costal Diaphragm [PDF]

BioMed Research International, 2016
Smaller diaphragmatic motor unit potentials (MUPs) compared to MUPs of limb muscles lead to the hypothesis that diaphragmatic muscle fibers, being the generators of MUPs, might be also smaller. We compared autopsy samples of costal diaphragm and vastus lateralis of healthy men with respect to fibers’ size and expression of slow myosin heavy chain ...

DNA methylation assessment from human slow- and fast-twitch skeletal muscle fibers [PDF]

Journal of Applied Physiology, 2017
A new application of the reduced representation bisulfite sequencing method was developed using low-DNA input to investigate the epigenetic profile of human slow- and fast-twitch skeletal muscle fibers. Successful library construction was completed with as little as 15 ng of DNA, and high-quality sequencing data were obtained with 32 ng of DNA ...

Molecular mechanisms underlying the impact of muscle fiber types on meat quality in livestock and poultry

Frontiers in Veterinary Science, 2023
In the past, the primary emphasis of livestock and poultry breeding was mainly on improving the growth rate, meat production efficiency and disease resistance.

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)

LncRNA-FKBP1C regulates muscle fiber type switching by affecting the stability of MYH1B

Cell Death Discovery, 2021
Long non-coding RNAs (lncRNAs) are well-known to participate in a variety of important regulatory processes in myogenesis. In our previous RNA-seq study (accession number GSE58755), we found that lncRNA-FKBP1C was differentially expressed between White ...
