从逆转录病毒载体用于基因治疗应用的早期阶段开始,人们就担心重组载体可能通过改变基因组整合位点附近的细胞原癌基因或肿瘤抑制基因的表达来诱导细胞转化(图6.1)。这种现象被称为插入突变,被描述为野生型伽玛逆转录病毒(以前称为小鼠肿瘤逆转录病毒)的一种特性,野生型伽玛逆转录病毒是本章描述的大多数临床试验中使用的重组载体的衍生原型病毒(见[178])。野生型逆转录病毒根据其转化特性分为两类:慢转化逆转录病毒和急性转化逆转录病毒。
From an early stage in the development of retroviral vectors for gene therapy applications, there has been a concern that recombinant vectors could elicit cellular transformation by altering expression of either cellular proto-oncogenes or tumor suppressor genes that are proximal to the genomic integration site (Fig. 6.1). This phenomenon, referred to as insertional mutagenesis, was characterized as a property of wild type gammaretroviral viruses (previously known as murine oncoretroviral viruses) which are the prototype virus from which the recombinant vectors used in the majority of the clinical trials described in this chapter were derived (reviewed in [178]). Wild type retroviruses fall into two categories with regards to their transforming properties: Slow transforming and acute transforming retroviruses.
