目的:包装已成功构建的受Ⅰ型单纯疱疹病毒(HerpessimplexvirusⅠ,HSV-Ⅰ)晚期表达基因-UL38启动子调控的、嗜肿瘤单纯疱疹病毒介导的,长臂猿白血病病毒致融性外膜糖蛋白(Gibbon ape leukemia virus membrance fusion glycopratein,GALV.fus)基因质粒(HSV-UL38P-GALV.fus),无肿瘤特异性巨细胞病毒启动子(Cytomegalovirus promoter,CMVP)GALV.fus质粒(HSV-CMVP-GALV.fus),GALV.fus基因片段被增强型绿色荧光蛋白(Enhanced green fluorescent protein,EGFP)基因片段所取代的治疗对照质粒(HSV-CMVP-EGFP),分别命名为Synco-2、Synco-1、Baco-1。方法:扩增已成功构建的HSV-UL38P-GALV.fus、HSV-CMVP-GALV.fus、HSV-CMVP-EGFP质粒,然后分别在Vero细胞用脂质体转染、包装成重组嗜肿瘤单纯疱疹病毒。重组单纯疱疹病毒的扩增及纯化采用Vero细胞及氯化铯纯化常规方法,病...
【英文摘要】
Objective:Package of constructed recombinant tumor-selective type I Herpes simplex virus vector plasmid containing UL38 and CMV promoter and GALV.fus gene (HSV-UL38P-GALV.fus、HSV-CMVP-GALV.fus),GALV.fus gene was replaced by EGFP in control plasmid (HSV-CMVP-EGFP). The three recombinant viruses were named Synco-2、Synco-1 and Baco-1 respectively。Methods: At first the three constructed plasmids were amplificated in coliform bacterium and transfected into Vero cells by using lipofectamine respectively. Then,the...
