摘要:
目的  探讨特异性启动子控制下嗜肿瘤Ⅰ型单纯疱疹病毒(HSV-Ⅰ)载体介导的长臂猿白血病病毒致融性外膜糖蛋白(GALV.fus)基因转导肺腺癌细胞的抗肿瘤作用。 方法  将重组HSV-Ⅰ载体质粒通过脂质体导入非洲绿猴肾细胞(Vero)中包装制备重组HSV-Ⅰ病毒,用来转染肺腺癌细胞(A549)和正常人胚胎成纤维细胞(HFL-Ⅰ GNHu 5)及裸鼠皮下肺癌转移模型,观察其体外及体内抗肿瘤作用及细胞毒性作用。统计学方法采用t-检验。 结果  成功包装重组HSV-Ⅰ病毒, BALB/c 裸鼠皮下接种A549细胞2周后均有肿瘤生长,成瘤率为100%。重组单纯疱疹病毒能特异性转染A549细胞,治疗组及对照组细胞存活率分别为20%及70%,病毒对A549细胞有明显的杀灭作用且对裸鼠皮下肺癌转移灶抑制明显。  结论  GALV.fus基因对肺癌细胞有强效的抗肿瘤作用,为临床肺癌治疗探索出一种新型基因治疗方法。
Abstract:
Objective    To investigate the antitumor effect of special promoter-controlled Gibbon ape leukemia virus membrane fusion glycoprotein (GALV.fus) mediated by type Ⅰ herpes simplex virus (HSV-Ⅰ) on lung adenocarcinoma.     Methods    Recombinant HSV-Ⅰ plasmids encoding GALV.fus was introduced into green monkey kidney cells(Vero)by liposome to amplify the virus, and then the virus was transfected into lung adenocarcinoma (A549), human fetal fibroblasts (HFL-Ⅰ GNHu 5) and human lung adenocarcinoma xenografts which were established in nude mice subcutaneously to observe antitumor and cytotoxic effect in vitro and in vivo; Recombined cytomegalovirus (CMV) containing GALV.fus or enhanced green fluorescence protein were served as control.     Results    Recombinant HSV-Ⅰ virus were packed successfully. Heterotransplantative tumourigenicity of the tumour was 100% in nude mice after A549 cells were inoculated. Recombinant HSV-Ⅰvirus exerted obvious antitumor effects in vitro, with relative survival rate of 23%, while for CMV virus containing GALV. fus, the rate was 20%, and for CMV virus encoding EGFP, the rate was 68%. Recombinant HSV-Ⅰvirus also showed striking antitumor effect on the implanted tumor.     Conclusion    GALV.fus has powerful effect against lung cancer in vitro and in vivo and maybe a promising candidate for gene therapy.
