Location of endoplasmic reticulum relative to sarcoplasmic reticulum in cultured chick myotubes

Biochemical Society Transactions, 1997
Calcium plays a major role as a second messenger modulating a wide range of cellular processes (1). Endoplasmic and sarcoplasmic reticulum calcium pumps (SERCAs) play a major role in controlling the levels of cytoplasmic calcium but the way in which these pumps are targeted to and maintained in specific cellular compartments is unclear.

Calcitonin gene-related peptide increases the expression of acetylcholinesterase in cultured chick myotubes

Neuroscience Letters, 1996
Calcitonin gene-related peptide (CGRP), a neuropeptide may play a role in the formation of neuromuscular junctions is synthesized by the motor neurons and is able to stimulate the expression of acetylcholine receptor (AChR) in cultured myotubes.

Chick myotubes in culture express high-affinity receptors for calcitonin gene-related peptide

Brain Research, 1989
Calcitonin gene-related peptide (CGRP) is a 37-amino acid neuropeptide that is expressed by many neurons of the vertebrate nervous system, including motoneurons of many species. It has been detected immunohistochemically in both cell bodies and motor terminals of motoneurons, suggesting that it may play a role at the neuromuscular junction.

The cAMP-dependent protein kinase mediates the expression of AChE in chick myotubes

NeuroReport, 2000
Calcitonin gene-related peptide (CGRP), a neuropeptide synthesized by motor neurons, stimulates the expression of AChR and AChE at the vertebrate neuromuscular junctions. The signaling mechanism of CGRP-induced AChE expression in muscle was determined both in vitro and in vivo. In cultured chick myotubes, the intracellular cAMP-dependent protein kinase

[3H]-nitrendipine binding in chick myotubes developing in culture.

Pharmacology, 1988
Binding studies with the [3H]-nitrendipine were performed in homogenates of chick skeletal myotubes developing in culture. The specific binding data suggested two classes of binding sites with high and low affinities for nitrendipine. No significant changes in the dissociation constants of both high- and low-affinity sites could be detected over the ...

Characterization of resting membrane potential and its electrogenic pump component in cultured chick myotubes

International Journal of Developmental Neuroscience, 1989
AbstractThe role of the electrogenic Na+‐K+ pump in the determination of the level of the resting membrane potential in cultured chick limb muscle was investigated. Transmembrane resting potential and ouabain‐sensitive86Rb‐uptake were measured in myotubes at different ages in culture from 2 to 10 daysin vitro. Inhibition of the Na+‐K+ pump with ouabain

Isolation and purification of myotube and myoblast nuclei from cultures of embryonic chick skeletal muscle

Experimental Cell Research, 1978
Abstract Methods are described for the preparation of purified myotubes from embryonic chick skeletal muscle cultures and the preparation of purified nuclei from both myotubes and myoblasts. Myotubes are released from the culture dish by digestion of their collagen substratum with collagenase, and purified by sucrose density gradient sedimentation ...

[In vivo evidence for bispecific myotubes containing chick and quail nuclei (author's transl)].

Archives d'anatomie microscopique et de morphologie experimentale, 1979
The nuclear specificity of 12 day embryonic skeletal muscle cells has been studied in ectopic limbs that developed after implantation of quail limb somatopleural mesoderm into chick hosts. In eleven cases, the nuclearity of the myotubes was homospecifically of chick type.
