摘要
腺病毒载体是目前肿瘤临床试验中使用最为广泛的载体之一。在过去的十几年里,随着人们对腺病毒活动周期的逐步了解,已经开发出了一系列专门针对恶性肿瘤细胞的靶向腺病毒载体。这些载体可以在特定的细胞中表达治疗性基因或进行自主复制,显示了其在肿瘤治疗方面的独特优势。但目前对腺病毒进行的各种改进方式都存在不同程度的缺陷,因此仍需进一步研究。文章讨论腺病毒载体用于肿瘤基因治疗方面的一些基本情况及其在临床应用的潜力。
Adenoviral vectors are one of the most popular vehicles for gene transfer currently being used in worldwide clinical trails for cancer, Over the past decade our knowledge of the adenoviral life cycle has permitted the targeting of adenoviral vectors to specific tumors, it can be manipulated to express therapeutic genes or to replicate specifically in certain cells. A variety of virus vectors have been employed to deliver genes to cells to provide either transient or permanent transgenes expression and each approach has its own advantages and disadvantages. This review discuss the basic concepts behind the use of adenoviral vectors for cancer gene therapy and their potential for clinical application.
