Dystrophic mouse myotubes exhibit reduced acetylcholine sensitivity and alpha-bungarotoxin binding in vitro, suggesting altered receptor function in muscle disease.
Acetylcholine (ACh) sensitivity in cultured myotubes from normal or dystrophic mice was investigated using conventional techniques. Dystrophic multinucleate myotubes were found to be less responsive to the ACh with respect to the control preparation. Such a reduced sensitivity to ACh in dystrophic myotubes was accompanied by a reduced binding to 125I-alpha-bungarotoxin. The possible biological significance of these results on the muscle disease is discussed.

Cossu et al. (1984) studied Muscular dystrophy. Dystrophic mutation vs. Normal myotubes was evaluated on Acetylcholine (ACh) sensitivity and binding to 125I-alpha-bungarotoxin. Dystrophic multinucleate myotubes demonstrated reduced sensitivity to acetylcholine and reduced binding to 125I-alpha-bungarotoxin compared to control preparations.
