肿瘤的遗传因素影响肿瘤发生的体内因素,首先是与调节控制细胞繁殖、识别邻近组织和合成特异性蛋白质等特性的遗传物质有关,也就是与细胞核内组成整套染色体的脱氧核糖核酸和蛋白质有关;其次就是可以影响肿瘤生长的机体内环境,这包括激素水平、代谢、免疫、神经精神因素等。这些因素以及机体对营养物质的摄取和利用能力,在一定程度上也是由遗传决定的。因此认为:遗传物质的改变是肿瘤发生的关键之一,也是分子遗传学中最迫切需要了解的课题。一、肿瘤的遗传问题为了研究肿瘤的遗传问题,世界上培育
Tumor genetic factors affecting tumor in vivo factors, first and regulation of cell proliferation control, identification of neighboring tissues and synthesis of specific proteins and other genetic material related to that is, with the nucleus to form the entire set of chromosome DNA and protein; The second is that the body can affect the growth of tumors in the environment, including hormone levels, metabolism, immune, neuropsychiatric factors. These factors, as well as the body’s ability to ingest and utilize nutrients, are also genetically determined to a certain extent. So that: genetic material changes is one of the key tumor, but also the most urgent need to understand the topics of molecular genetics. First, the genetic problems of cancer In order to study the genetic problems of cancer, the world nurtured
