当腺病毒与条件复制腺病毒(CRAd)联合感染同一癌细胞时,可以改善腺病毒介导的基因转移到肿瘤肿块中。我们研究了两种腺病毒(Ads),一种表达E2F-1 (AdE2F-1),另一种表达缺乏反活化结构域的E2F-1的截短形式(AdE2Ftr),当与溶瘤性Adhz60联合使用时,增强转基因表达的效率和杀死癌症的有效性。我们发现,Adhz60的AdE2F-1实际上通过抑制周期蛋白e启动子和降低病毒复制所需的早期和晚期结构蛋白的表达来降低E2F-1的表达和病毒复制。相比之下,AdE2Ftr与Adhz60在体外和体内均导致E2Ftr表达增加、AdE2Ftr复制增加和癌细胞死亡。这些结果表明,AdE2Ftr与CRAd偶联可增强AdE2Ftr介导的癌细胞死亡。
Adenovirus-mediated gene transfer into a tumor mass can be improved by combining it with conditionally-replicating adenovirus (CRAd) when both vectors co-infect the same cancer cell. We investigated the efficiency of enhancing transgene expression and effectiveness of cancer killing of two advenoviruses (Ads), one expressing E2F-1 (AdE2F-1) and another expressing a truncated form of E2F-1 that lacks the transactivation domain (AdE2Ftr), when combined with oncolytic Adhz60. We found that AdE2F-1 with Adhz60 actually decreased E2F-1 expression and viral replication through a mechanism apparently involving repression of the cyclin-E promoter and decreased expression of early and late structural proteins necessary for viral replication. In contrast, AdE2Ftr with Adhz60 resulted in increased E2Ftr expression, AdE2Ftr replication, and cancer cell death both in vitro and in vivo. These results indicate that AdE2Ftr coupled with a CRAd enhances AdE2Ftr-mediated cancer cell death.
