细胞癌基因结构与功能的发现是近年来舯瘤研究的重大突破。目前,至少在脊椎动物细胞中确定了32种与逆转录酶病毒癌基因同源的细胞癌基因,其中有20种已大体在人基因组中定位。最近,有人按癌基因的结构、基因产物及其功能相似性将癌基因分为五大癌基因家族。癌基因家族的分类为了 The discovery of the structure and function of the oncogene is a major breakthrough in the study of the tumor in recent years. Currently, at least 32 types of oncogenes that are homologous to the retroviral oncogene have been identified in vertebrate cells, of which 20 have been roughly mapped in the human genome. Recently, some people have classified oncogenes into five oncogenes by oncogene structure, gene products and their functional similarities. Classification of oncogene families in order
