title: Chromosome abnormalities in bovine papillomavirus type 1-transformed Syrian hamster cells before and after tumor formation.
abstract: Syrian hamster embryonic fibroblasts transformed by infection with bovine papillomavirus type 1 cause tumors when inoculated into hamsters. Chromosome examinations revealed several abnormal clones in the transformed fibroblasts and a variety of additional markers in three tumors. Only one aberration, trisomy 11, was present in each cell. The extra chromosome #11, thus, is considered to be essential for tumor formation in this model system.
