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.

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.

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 ...

[ 3 H]-Nitrendipine Binding in Chick Myotubes Developing in Culture
Pharmacology, 2008Binding 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 ...

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 ...

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.

Location of endoplasmic reticulum relative to sarcoplasmic reticulum in cultured chick myotubes
Biochemical Society Transactions, 1997Calcium 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.

Journal of Comparative Neurology, 1986
AbstractA study has been made of the development of muscle nerves to primary myotube clusters destined to become the flexor carpi ulnaris (fcu) and flexordigitorum profundus (fdp) muscles in the avian forelimb. Myotubes and nerves were identified by immunofluorescent techniques using antibodies to the heavy and light subunits of myosin and ...

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 ...
