In striated muscle, adenosine-5'-triphosphate (ATP) potentiates the responses to acetylcholine. The underlying biochemical events are unknown. Here we report that ATP, externally applied to chick myotubes, induces a rapid, dose-dependent accumulation of intracellular inositol triphosphate which is correlated with a decrease in phosphatidyl 4,5 ...

Caffeine contracture in the cultured chick myotube
Journal of Cellular Physiology, 1986AbstractA possible function of Ca store site in cultured chick myotubes was examined by recording contraction of the myotube with special reference to the effect of caffeine. Caffeine at low concentrations (below 1 mM), applied focally on the myotube through a micropipette with a pressure pulse, elicited focal contraction without membrane potential ...

Trifluoperazine Stimulates Acetylcholine Receptor Synthesis in Cultured Chick Myotubes
Journal of Neurochemistry, 1984Abstract: Acetylcholine receptor appearance rate in the presence of the phenothiazines trifluoperazine and chlorpromazine was measured in cultured embryonic chick myotubes by means of 125I‐α‐bungarotoxin. At drug concentrations of 5 to 10 × 10−6M, receptor appearance rate was significantly enhanced while receptor half‐life, cellular protein, net ...

Microwave effects on acetylcholine‐induced channels in cultured chick myotubes
Bioelectromagnetics, 1988AbstractThe behavior of cultured myotubes from chick embryos exposed to microwaves has been experimentally analyzed. Recordings of acetylcholine‐induced currents have been obtained via patch‐clamp techniques using both cell‐attached (single‐channel current recording) and whole‐cell (total current recording) configurations.

Effects of Serum Deprivation on Myofibrillar Proteolysis in Chick Myotube Cultures
Bioscience, Biotechnology, and Biochemistry, 2003We examined the effects of serum deprivation on myofibrillar proteolysis in chick myotubes. Myotubes were incubated with serum-free medium for 24 hours. N(tau)-methylhistidine release, as an index of myofibrillar proteolysis, as well as protease activities such as calpain, proteasome, and cathepsins (B+L and D) activities were increased by serum ...

Chick embryo myotubes contain transferrin receptors and internalize and recycle transferrin
Journal of Neuroscience Research, 1986AbstractEmbryonic chick skeletal myotubes grown in cell culture require transferrin to provide iron for proliferation and differentiation. We demonstrate here that cultured myotubes contain transferrin receptors as demonstrated by the finding of specific, saturable, and reversible high‐affinity binding sites.

Evidence for a functional role of acetylcholinesterase in cultured chick myotubes
Brain Research, 1983This study was undertaken in order to assess the functional role of acetylcholinesterase (AChE) in cultures of chick skeletal muscle cells. Cultures of skeletal myotubes were prepared by mechanical dissociation of limb muscle removed from 11-day-old chick embryos and plating at a concentration of 0.8 X 10(6) cells/ml.

Some characteristics of myotubes cultured from slow and fast chick muscles
Journal of Cellular Physiology, 1974AbstractExplant cultures were prepared from the slow anterior latissimus dorsi muscle and the fast posterior latissimus dorsi muscle of 15 day chick embryos. The morphology and growth pattern of myotubes from the two types of muscle were very similar. Intracellular microelectrode studies did not reveal consistent differences between the myotube types ...

Block of single acetylcholine-activated channels in chick myotubes by alkylguanidines
Pfl�gers Archiv European Journal of Physiology, 1986The mechanism of block of single acetylcholine-activated channels by alkylguanidines was studied by means of the gigaohm seal, patch clamp technique on chick myotubes. The single channel current-voltage relationship in symmetrical Cs solutions was linear over membrane potentials from -100 mV to +100 mV with the reversal potential close to 0 mV.
