癌基因即 Oncogene,也有称为致癌基因、肿瘤基因等。这种基因不仅具有致癌作用,而且能使细胞维持癌的性质。一、癌基因研究的初期六十年代,在细胞水平上开始进行了致癌机理的研究。当时曾推测:癌细胞之所以那样活跃地反复分裂、增殖,甚至转移后,仍具有癌的性质,可能是由于癌的遗传信息在起作用。要对此进行研究,最适宜的材料 The Oncogene, an oncogene, is also known as an oncogene, an oncogene, and the like. This gene not only has a carcinogenic effect, but also enables the cell to maintain its cancerous properties. First, in the early 1960s, oncogene research began to investigate the mechanism of carcinogenesis at the cellular level. At that time, it was speculated that the reason why cancer cells repeatedly divide, proliferate, and even metastasize after they have become cancerous, may be due to the genetic information of the cancer. To study this, the most suitable material
