科学家最近指出,一个新的突变基因可能在许多种常见癌症(包括肺癌和乳腺癌)的发生中起作用。伦敦大学医学院及其他研究所的研究人员在一个患有胃B细胞淋巴瘤的病人体内发现了突变的肿瘤基因,他们称其为Bc110。随后他们在其他肿瘤标本中发现了同样突变了的肿瘤基因,这些癌包括乳腺癌、肺癌和结肠癌。该研究组负责人Martin Dyer指出,这是第二个被发现与如此大量的癌症有关的基因。第一个基因是P53,P53在大约50％的各种癌中是异常的。初步结果表明,Bc110至 Scientists recently pointed out that a new mutant gene may play a role in the occurrence of many common cancers, including lung cancer and breast cancer. Researchers at the University of London School of Medicine and other institutes discovered a mutated tumor gene in a patient with gastric B-cell lymphoma that they called Bc110. Then they found the same mutated tumor genes in other tumor specimens, including breast cancer, lung cancer, and colon cancer. Martin Dyer, head of the research group, pointed out that this is the second gene that has been found to be associated with such a large number of cancers. The first gene is P53, which is abnormal in about 50% of all cancers. Preliminary results show that Bc110 to
