RESUMO

Low passage Fischer rat embryo cultures, which are normally very resistant to transformation by 3-methylcholanthrene but are highly susceptible when chronically infected with the Rauscher murine leukemia virus, were completely protected from transformation by methylcholanthrene when treated with neutralizing antibody specific for the leukemia virus prior to and during treatment with methylcholanthrene. Sister cultures were not protected by neutralizing antibody specific for the B-tropic radiation leukemia virus. This demonstrates clearly a definite type specific role for Rauscher murine leukemia virus in the 2-methylcholanthrene transformation system in rat cells.
