Frontiers in Genetics, 2022 MicroRNAs (miRNAs) might play critical roles in skeletal myofiber specification. In a previous study, we found that chicken miR-499-5p is specifically expressed in slow-twitch muscle and that its potential target gene is SOX6. In this study, we performed

Cell Communication and Signaling, 2023 Background Skeletal muscle is comprised of heterogeneous myofibers that differ in their physiological and metabolic parameters. Of these, slow-twitch (type I; oxidative) myofibers have more myoglobin, more mitochondria, and higher activity of oxidative ...

Regulation of skeletal muscle plasticity by the transcriptional coregulators PGC-1α and NCoR1 [PDF]
, 2013 Skeletal muscle plasticity is regulated by a wide range of factors, among which environmental stimuli such as exercise play a central role. Importantly, changes in skeletal muscle phenotype exert a direct impact on health and risk to premature death.

Quantitative analysis of dystrophin in fast‐ and slow‐twitch mammalian skeletal muscle [PDF]
FEBS Letters, 1992 The relative tissue content of dystrophin has been evaluated in the slow‐twitch soleus (primarily type I fibers) and fast‐twitch vastus lateralis (primarily type IIb filbers) muscles of the rat and mouse, as well as in human biopsy samples from the vastus lateralis and gluteus maximus muscles, using a sensitive immunochemical assay.

Characterization of RyR1-slow, a ryanodine receptor specific to slow-twitch skeletal muscle [PDF]
, 2000 Two distinct skeletal muscle ryanodine receptors (RyR1s) are expressed in a fiber type–specific manner in fish skeletal muscle (11). In this study, we compare [3H]ryanodine binding and single channel activity of RyR1-slow from fish slow-twitch skeletal ...

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.

EXERCISE MYOPATHY: CHANGES IN MYOFIBRILS OF FAST-TWITCH MUSCLE FIBRES [PDF]
, 2014 The purpose of the present study was to determine the relationships between the changes of myofibrils in fast-twitch oxidative-glycolytic (type IIA) fibres and fast-twitch glycolytic (type IIB) muscle fibres, protein synthesis and degradation rate in ...
