1引言1.1肿瘤发生与细胞受损及功能异常密切相关病因学研究表明,外在化学、物理、生物等因素均可能使机体细胞受到损害;内环境紊乱、免疫功能下降等则使机体抗肿瘤能力降低内外因素共同作用致基因突变,突变细胞降低生长因子需求表现出肿瘤细胞的不死性特点。细胞膜葡萄糖转运增强 1 Introduction 1.1 Tumor occurrence and cell damage and dysfunction are closely related to etiology studies have shown that external chemical, physical, biological and other factors may damage the body cells; internal environment disorders, decreased immune function so that the body’s anti-tumor ability Reduce the combined effect of internal and external factors caused by gene mutations, mutant cells to reduce the demand for growth factors showed the characteristics of tumor cells of the undead. Cell membrane glucose transport increased
