基因的多效性 癌细胞不正常行为的特点是不受控制的生长;在不正常的范围内依赖厌氧代谢以及膜具有特异性肿瘤抗原。 也许一个单独的主要作用细胞成分被打开,然后在表现型上它能同时引出大量的变化。 Marguerite Vogt等首次使用多瘤病毒在体外感染地鼠胚胎纤维母细胞,得到了转化细胞。当转化细胞注入幼龄大鼠时,即可生成肿瘤。 Gene Pleiotropicity The abnormal behavior of cancer cells is characterized by uncontrolled growth; in an abnormal range reliance on anaerobic metabolism and membrane-specific tumor antigens. Perhaps a single major cell component of action is turned on, and then it can simultaneously elicit a large number of changes in phenotype. For the first time, Marguerite Vogt et al. used a polyomavirus to infect hamster embryonic fibroblasts in vitro to obtain transformed cells. Tumors can be generated when transformed cells are injected into young rats.
