Skeletal Fiber Type in Muscle Pain and Dysfunction [PDF]
BiomedicinesDifferent types of skeletal muscle fibers display marked heterogeneity in metabolic, mechanical, and regenerative properties. However, their role in chronic musculoskeletal pain remains insufficiently integrated into clinical models.

Specification of vertebrate slow-twitch muscle fiber fate by the transcriptional regulator Blimp1
Developmental Biology, 2008 Skeletal muscles of vertebrates are typically composed of slow- and fast-twitch fibers that differ in their morphology, gene expression profiles, contraction speeds, metabolic properties and patterns of innervation. During myogenesis, how muscle precursors are induced to mature into distinct slow- or fast-twitch fiber-types is inadequately understood ...

Characterization of Fiber-Type Composition and Phosphoproteins of Fast- and Slow-Growing Broilers [PDF]
AnimalsMuscle fibers exhibit high plasticity: both the fast-twitch fiber type and slow-twitch fiber type can mutually transform under the regulation of phosphorylation.

Mitochondrial dynamics define muscle fiber type by modulating cellular metabolic pathways
Cell Reports, 2023 Summary: Skeletal muscle is highly developed after birth, consisting of glycolytic fast-twitch and oxidative slow-twitch fibers; however, the mechanisms of fiber-type-specific differentiation are poorly understood.

Measurement of Myoplasmic Calcium Transients in Mouse Slow-Twitch Muscle Fibers [PDF]
Biophysical Journal, 2012 Bundles of intact fibers from soleus muscles of adult mice were isolated by dissection and one fiber within a bundle was micro-injected with either furaptra or mag-fluo-4, two low-affinity rapidly-responding Ca2+ indicators. Fibers were activated by action potentials to elicit changes in indicator fluorescence (dF), a monitor of the myoplasmic free Ca2+

Life, 2023 The ratio of fast- and slow-twitch fibers in human skeletal muscle is variable and largely determined by genetic factors. In this study, we investigated the contribution of microRNA (miRNA) in skeletal muscle fiber type composition.

Slow-Twitch Fiber Proportion in Skeletal Muscle Correlates With Insulin Responsiveness [PDF]
The Journal of Clinical Endocrinology & Metabolism, 2013 The metabolic syndrome, characterized by central obesity with dyslipidemia, hypertension, and hyperglycemia, identifies people at high risk for type 2 diabetes.Our objective was to determine how the insulin resistance of the metabolic syndrome is related to muscle fiber composition.Thirty-nine sedentary men and women (including 22 with the metabolic ...

Coexistence of two calsequestrin isoforms in rabbit slow‐twitch skeletal muscle fibers [PDF]
FEBS Letters, 1992 The cardiac and skeletal muscle isoforms of calsequestrin (CS), the low affinity, high capacity Ca2+ binding protein localized in the lumen of sarcoplasmic reticulum, are the products of two different genes (Fliegel, L., Leberer, E., Green, N.M. and MacLennan, D.H. (1982) FEBS Lett.
