title: Activated c-K-ras and c-N-ras oncogenes in 3-methylcholanthrene-induced BALB/c fibrosarcomas.
abstract: DNAs from fourteen fibrosarcomas induced by 3-methylcholanthrene (MCA) in BALB/c mice were analyzed for the presence of transforming oncogenes following transfection on NIH3T3 cells. Six transfection-positive DNAs contained an activated ras gene: four c-K-ras and two c-N-ras. These results demonstrate that c-K-ras is not the only oncogene of the ras family activated in MCA-induced murine fibrosarcomas as was previously indicated.
