人肺癌PR 310和PR 371含有激活的c-K-ras癌基因。发现PR 371的癌基因在第一编码外显子的密码子12处存在突变,其在编码的p21蛋白中将甘氨酸替换为半胱氨酸。我们在这里报告,PR 310肿瘤的转化基因包含在第二个编码外显子的突变。密码子61处的A→T转换导致c-K-ras基因产物中组氨酸而不是谷氨酰胺的掺入。通过构建c-K-ras/c-H-ras嵌合基因,我们表明,这种点突变是足以赋予潜在的转化torasgenes,和hybridrasgene编码的蛋白质突变体在两个密码子12和61也能够转化NIH 3 T3细胞。分析了ras基因突变体编码的p21蛋白在密码子12、61或两者的相对转化能力。我们的研究还表明,包括第四个在内的ras基因的编码外显子可以互换,并且嵌合p21 ras蛋白在正常啮齿动物建立的细胞系中保留了其致癌能力。
The human lung carcinomas PR310 and PR371 contain activated c-K-rasoncogenes. The oncogene of PR371 was found to present a mutation at codon 12 of the first coding exon which substitutes cysteine for glycine in the encoded p21 protein. We report here that the transforming gene of PR310 tumor contains a mutation in the second coding exon. An A→T transverslon at codon 61 results in the incorporation of histidine instead of glutamine in the c-K-rasgene product. By constructing c-K-ras/c-H-raschimeric genes we show that this point mutation is sufficient to confer transforming potential torasgenes, and that a hybridrasgene coding for a protein mutant at both codons 12 and 61 is also capable of transforming NIH3T3 cells. The relative transforming potency of p21 proteins encoded byrasgenes mutant at codons 12, 61 or both has been analyzed. Our studies also show that the coding exons ofrasgenes, including the fourth, can be interchanged and the chimeric p21rasproteins retain their oncogenic ability in normal rodent established cell lines.
