Peter Newmark文章:大约一年以前,人们发现,人膀胱癌细胞株的转化基因(致癌基因)与正常细胞相应的非转化基因之间只有一个核苷酸(和一个氨基酸)之差。此后Feiberg等人曾致力于寻找同一突变的其他例证,但没有获得成功。最近Yuasa等人却 Peter Newmark Article: About a year ago, it was discovered that there was only one nucleotide (and one amino acid) difference between a transforming gene (oncogene) in a human bladder cancer cell line and a non-transformed gene corresponding to a normal cell. Since then, Feiberg et al. have devoted themselves to finding other examples of the same mutation but have not been successful. Recently Yuasa et al.
