title: [Identification of the transforming Ha-ras gene in human melanoma, neuroblastoma and breast cancer cells].
abstract: Preparations of DNA isolated from malignant melanoma (Ja heterotransplant), neuroblastoma (L-AN-1 cell line) and breast cancer (SK-BR-3 cell line) induced a high incidence of transformation of recipient NIH 3T3 cells in two consecutive cycles of transfection. Transformed NIH 3T3 cells appeared to be highly tumorigenic in newborn BALB/c mice. The analysis of DNA samples isolated from primary and secondary NIH 3T3 transformants identified Alu-repetitive DNA sequences of human genome as well as additional sequences homologous to ras-family oncogene. Transforming c-Ha-ras I gene was identified for the first time in NIH 3T3 cells transformed by preparations of DNA isolated from human malignant melanoma, neuroblastoma and breast cancer.
