May mark failed maturation in dystrophy models; leaves open translational relevance to human muscle disease.
Feit et al. (1982) studied Avian muscular dystrophy. Dystrophic avian pectoral muscle vs. Normal avian pectoral muscle was evaluated on Isotype pattern of tropomyosin. Avian dystrophic pectoral muscle showed persistent expression of the beta-subunit of tropomyosin, unlike normal adult pectoral muscle which contains only the alpha-subunit.
