基因重复是生物进化的重要来源,在此基础上可产生基因倒转、移位、替换、缺失等基因重排,为原始基因保留在高等生物基因库中提供了可能。早期胚胎发育的基因控制和真核细胞的起源,反映基因重复在基因进化的历程肿瘤形成过程中,原始基因在特定的微环境作用下,被激活表达,而形成肿瘤。我们认为癌症是基因的返祖现象。 Gene duplication is an important source of biological evolution, on the basis of gene rearrangement, translocation, replacement, deletion and other gene rearrangement, the original gene retained in the higher biological gene pool provides the possibility. Gene Control of Early Embryonic Development and Origin of Eukaryotic Cells, Reflecting Gene Repetitions During the course of gene evolution, the tumor is formed by the activation of the original gene under the action of a specific microenvironment. We think cancer is the ancestral phenomenon of genes.
