1、About 30 percent of human lung cancer patients have mutations in Kras.───大约30%的人类肺癌病人有Kras突变。
2、The KRAS proto-oncogene product lies downstream of EGFR, and the mutation frees the receptor from normal regulation in cell-growth control.───原癌基因KRAS是表皮生长因子受体下游产物，它的突变使其不受在细胞生长控制中正常调节的受体影响。
3、The other patients with the normal, or wild-type, KRAS genes are likely to respond to these drugs, he said.───他表示，其他病患是正常的野生型KRAS基因，对这些药物比较可能有反应。
4、About 40% of these patients have a KRAS gene mutation, and respond poorly to such antibodies.───约40%患者有KRAS基因突变而对这类抗体反应很差。
5、A few years ago, several groups of scientists began to seek out new cancer drugs by targeting a protein called KRAS.───几年前，几组科学家开始把目标投向一种叫KRAS的蛋白，以寻找新的抗癌药物。
6、KRAS mutations detected, 17% were outside of codons 12 and 13.───KRAS的基因突变中，我们检测到17%是位于12号和13号密码子以外的。
7、The KRAS protein transmits signals received on the outside of a cell to its interior and is therefore crucial for regulating cell growth.───KRAS蛋白将细胞外部获得的信号传导至细胞内部，因此对控制细胞生长有重要作用。
8、Kras gene, one of the oncogene, is frequently mutated in tumors.───Kras基因是一种癌基因，在肿瘤中的突变率较高。
9、The researchers said the wild type of KRAS is found in around 65 per cent of colorectal cancer patients.───研究者说大约65%的直肠癌患者的KRAS基因是野生型的。
