癌基因原是指某些可以引起肿瘤的病毒(肿瘤病毒)核酸所携带的可致癌的片段,即病毒癌基因(V-oncogene).由于基因工程和基因转移技术的发展和建立,人们已经在正常人的体细胞中分离了多种不同的癌基因,即细胞癌基因(C-oncogene).这些基因平时不活动(即不表达)或活动甚微,但一旦被激活,就大量表达,产生大量的特异性蛋白,从而发生癌变.为了表彰意大利生物化学家Rita Levj- Oncogene originally refers to a carcinogenic fragment carried by certain tumor-causing virus (tumor virus) nucleic acids, namely the viral oncogene (V-oncogene). Because of the development and establishment of genetic engineering and gene transfer technology, people have Normal human somatic cells are isolated from many different oncogenes, the cell oncogenes (C-oncogene). These genes are usually inactive (ie, not expressed) or have little activity, but once activated, they are expressed in large quantities. A large number of specific proteins that can become cancerous. In recognition of Italian biochemist Rita Levj-
