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.
对由3-甲基胆蒽(MCA)诱导BALB/c小鼠产生的14个纤维肉瘤的DNA进行分析,以检测转染至NIH3T3细胞后转化癌基因的存在情况。6个转染阳性的DNA含有激活的ras基因:4个c-K-ras和2个c-N-ras。这些结果表明,c-K-ras并非如之前所指出的那样,是MCA诱导的小鼠纤维肉瘤中唯一被激活的ras家族癌基因。
