肿瘤,是机体内某一类细胞的不正常增生,肿瘤发生的根源在机体自身的基因里,当致癌因子破坏了特定细胞中某一关键靶基因的DNA时,往往就会引起细胞的突变。突变细胞无限制地增生,最终形成越来越大的细胞团块,这就是肿瘤,在对肿瘤发生奥秘的探索中,致癌基因与抗致癌基因的发现,使“征服癌症”有了实现的可能,本文作者从一个全新的角度对此作了论述。 Tumors are abnormal proliferations of certain types of cells in the body. The origin of tumors is in the body’s own genes. When carcinogenic factors destroy the DNA of a key target gene in a specific cell, they often cause mutations in the cells. The mutant cells proliferate indefinitely, eventually forming larger and larger cell clumps. This is the tumor. In the exploration of the mystery of tumorigenesis, the discovery of oncogenes and anti-oncogenes has enabled the realization of “conquering cancers.” Probably, this article discusses this from a completely new perspective.
