肿瘤特异性启动子可驱动目的 基因在肿瘤细胞中高效特异性表达,目前常用的有甲胎蛋白启动子、癌胚抗原启动子、前列腺特异性抗原启动子、人端粒酶逆转录酶启动子和多药耐药基因启动子等.利用双启动子、增强子、调控元件或其他物化因素对启动子进行修饰或改造,可增强目的 基因在肿瘤细胞中的表达和定位.肿瘤特异性启动子可耦联自杀基因、抑癌基因、反义核酸、细胞凋亡基因和BNA干扰等,在肿瘤基因靶向治疗中发挥重要作用.
腫瘤特異性啟動子可驅動目的 基因在腫瘤細胞中高效特異性錶達,目前常用的有甲胎蛋白啟動子、癌胚抗原啟動子、前列腺特異性抗原啟動子、人耑粒酶逆轉錄酶啟動子和多藥耐藥基因啟動子等.利用雙啟動子、增彊子、調控元件或其他物化因素對啟動子進行脩飾或改造,可增彊目的 基因在腫瘤細胞中的錶達和定位.腫瘤特異性啟動子可耦聯自殺基因、抑癌基因、反義覈痠、細胞凋亡基因和BNA榦擾等,在腫瘤基因靶嚮治療中髮揮重要作用.

Tumor-specific promoters can induce high-efficiency and specific expression of exogenous genes in tumor cells. At present, commonly used promoters include alpha-fetoprotein promoter, carcinoembryonic antigen promoter,prostate specific antigen promoter,human telomerase reverse transcriptase promoter and multidrug resistance gene promoter and etc. Dual promoters, enhancer, regulatory element and other physical or chem-ical factors could be used to reconstruct or modify promoters to increase the expression and location of exogenous genes in tumor cells. Tumor-specific promoters play an important role in cancer gene targeted therapy by cou-pling with suicide gene, anti- oncogene, antiseuse nucleic acid, apoptosis gene and RNA interference.
