title: High frequency of c-K-ras activation in 3-methylcholanthrene-induced mouse thymomas.
abstract: Thymic lymphomas were induced in RJF mice by percutaneous application of 3-methylcholanthrene (MCA). DNAs from 83% of the tumors analyzed contained a transforming c-K-ras gene. The high frequency of c-K-ras oncogene activation in response to MCA seems to favor the concept that the activation of c-K-ras is related to the specificity of the mutagenic effect of MCA.
