  • Title: Role of cell division in differentiation of myoblasts infected with a temperature-sensitive mutant of Rous sarcoma virus.
    Author: Falcone G, Boettiger D, Alemà S, Tatò F.
    Journal: EMBO J; 1984 Jun; 3(6):1327-31. PubMed ID: 6086316.
    Abstract:
    The relationship between a potential requirement for cell DNA synthesis and the expression of differentiated muscle cell functions was investigated using primary chicken embryo myoblasts infected with a temperature-sensitive mutant of Rous sarcoma virus (RSV). Under optimized conditions, transformed myoblasts growing at the permissive temperature could differentiate into multinucleated myotubes, express muscle-specific myosin, desmin and acetylcholine receptors in the absence of DNA synthesis and cell division following a shift to the non-permissive temperature. Furthermore, the experiments demonstrate that individual RSV-infected myoblasts have two options: either to divide and express the transformed phenotype or to withdraw from the cell cycle and differentiate into myotubes. The choice between these options appears to depend on the protein-kinase activity of pp60src, the src gene product.
