美国马萨诸塞州理工学院Robert Wein-berg和美国国立癌症研究所MBarbacid领导下的两个研究小组对于人癌基因有了新的发现,即人癌基因与相应的正常细胞基因仅有一个核苷酸之差。美国哈佛大学的JonothanLogan和John Cairns把这一发现称做是对癌症进行的长期而艰难曲折的探索过程中迄今最为惊人的发现之一。上述两个研究小组是分别而各自独立进行研究的,但他们的发现却是相同的。他们的发现,其要点如下: 膀胱癌细胞中的一个基因与相应的正常基因所不同者,仅仅是DNA中一个特定的鸟嘌 Two research groups under the leadership of Robert Weinberg of the Massachusetts Institute of Technology and MBarbacid of the National Cancer Institute of the United States have made new discoveries in the human oncogene, that is, the human oncogene is only one nucleotide away from the corresponding normal cellular gene. difference. Jonothan Logan and John Cairns of Harvard University in the United States called the discovery one of the most amazing discoveries in the long-term and painstaking exploration of cancer. The above two research groups conducted separate and independent research, but their findings were the same. The main points of their discovery are as follows: A gene in a bladder cancer cell is different from the corresponding normal gene and is only a specific bird in the DNA.
