Frontiers in Aging Neuroscience, 2019 In addition to driving contraction of skeletal muscles, acetylcholine (ACh) acts as an anti-synaptogenic agent at neuromuscular junctions (NMJs). Previous studies suggest that aging is accompanied by increases in cholinergic activity at the NMJ, which ...

The significance of lipoprotein lipase in rat skeletal muscles
Journal of Lipid Research, 1977 Lipoprotein lipase was assayed in extracts of acetone-ether powders of rat skeletal muscles. Enzyme activity in soleus had typical characteristics of lipoprotein lipase in other tissues: inhibition by molar NaCl and protamine sulfate and activation by ...

Skeletal Muscle Fiber Size and Capillarity
Experimental Biology and Medicine, 1978 SummaryThe ATPase technique following preincubation in an acid medium (pH 3.8–4.0) was used to visualize capillaries. After preincubation at a pH of 4.5, in combination with the DPNH tetrazolium reductase, it was used to identify fiber types. A positive correlation has been demonstrated between fiber cross sectional area and C:F, indicating that large ...

Tropomyosin 3 (TPM3) function in skeletal muscle and in myopathy
Skeletal Muscle, 2023 The tropomyosin genes (TPM1-4) contribute to the functional diversity of skeletal muscle fibers. Since its discovery in 1988, the TPM3 gene has been recognized as an indispensable regulator of muscle contraction in slow muscle fibers.

Microtubule-mediated GLUT4 trafficking is disrupted in insulin-resistant skeletal muscle
eLife, 2023 Microtubules serve as tracks for long-range intracellular trafficking of glucose transporter 4 (GLUT4), but the role of this process in skeletal muscle and insulin resistance is unclear.

Obestatin controls skeletal muscle fiber-type determination [PDF]
Scientific Reports, 2017 AbstractObestatin/GPR39 signaling stimulates skeletal muscle growth and repair by inducing both G-protein-dependent and -independent mechanisms linking the activated GPR39 receptor with distinct sets of accessory and effector proteins. In this work, we describe a new level of activity where obestatin signaling plays a role in the formation, contractile

Influence of skeletal muscle heterogeneity on autophagic signaling and response
Autophagy ReportsSkeletal muscle is a heterogeneous tissue composed of fibers with distinct contractile, metabolic, and molecular characteristics. This intrinsic heterogeneity influences how individual fibers respond to physiological stimuli, pathological stress, and ...
