We have developed a novel technique to incorporate and stably express foreign genes in adult rat skeletal muscle in vivo. Endogeneous satellite cells in skeletal muscle regenerating from bupivacaine damage were infected with an injected retrovirus containing the Escherichia coli beta-galactosidase gene under the promoter control of the Moloney murine leukemia virus long-terminal repeat. Constitutive and stable expression of beta-galactosidase activity was observed in muscle fibers after 6 days and 1 mo of muscle regeneration. Two patterns of expression were observed, diffuse expression within fibers and focal expression associated with the sarcolemma. This technique will allow future experiments with muscle-specific genes and promoters to study the physiological regulation of skeletal muscle gene expression in the intact adult mammal. Furthermore, the technique of stimulating stem cell proliferation to allow retroviral-mediated gene transfer may be generally applicable to other tissues.

Caveolin-3, a muscle-specific member of the caveolin family, is strongly localized to the neuromuscular junction (NMJ) in adult rat muscle fibers, where it co-localizes with α-bungarotoxin staining. In 24-month-old rats, less distinct staining corresponds with the normal aging changes in the NMJ. After denervation, the pattern and intensity of staining begin to break up as early as 3 days, and by 10 days little staining remains. The functional implications of this concentration of caveolin-3 at the NMJ remain obscure, but it is possible that its absence could account for some of the phenotypic characteristics of individuals with caveolin-3 mutations.
