title: Transformation of hamster kidney cells by BK papovavirus DNA.
abstract: Supercoiled BK papovavirus DNA was shown to transform hamster kidney cells using the calcium phosphate co-precipitation technique. The transformed cells contained intranuclear T-antigen(s) and rescuable virus and produced progressively growing tumors when inoculated into hamsters. A novel finding was the production in tumor-bearing animals of antinuclear antibody, which reacted against normal, untransformed cells; in addition, tumor serum contained antibody against virus-specific T-antigen(s).
