癌基因目前认为是一类控制正常细胞生长发育的基因,普遍存在于正常动物细胞中,可在多种理化因素的诱导下,发生结构和功能的改变,从而使细胞发生恶变。生长因子一般认为是一种多肽分子,能与靶细胞膜上的高亲和性受体特异结合,刺激细胞合成DNA,使细胞增殖。近几年来,由于分子生物学的迅猛发展,已将某些癌基因与生长因子有机地联系起来了。已发现有些癌基因编码生长因子、生长因子受体或介导生长因子作用的因子。胶质瘤是一种常见的脑部肿瘤。在对它 Oncogene is currently considered as a type of gene that controls the growth and development of normal cells. It is ubiquitous in normal animal cells. Under the induction of various physical and chemical factors, structural and functional changes can occur, resulting in malignant transformation of cells. Growth factors are generally considered to be a polypeptide molecule that can specifically bind to a high-affinity receptor on the target cell membrane, stimulate the cells to synthesize DNA, and make cells proliferate. In recent years, due to the rapid development of molecular biology, certain oncogenes have been organically linked to growth factors. Some oncogenes have been found to encode growth factors, growth factor receptors, or factors that mediate the action of growth factors. Gliomas are a common brain tumor. In it
