A Burkitt lymphoma cell line infected in vitro with a transformation-defective mutant recombinant Epstein-Barr virus (EBV) was used to attempt marker rescue of transformation competence by transfection with cloned wild-type DNA. EBV replication was induced in the transfected cells, and wild-type EBV DNA recombined via flanking homologous sequences adjacent to the deletion, resulting in a virus which transformed primary B lymphocytes in vitro. This strategy should be useful for molecular genetic analysis of the role of part or all of any gene in cell growth transformation.
用一种体外感染了转化缺陷型突变重组爱泼斯坦-巴尔病毒(EBV)的伯基特淋巴瘤细胞系,通过用克隆的野生型DNA转染来尝试挽救转化能力标记。在转染细胞中诱导EBV复制,野生型EBV DNA通过缺失侧翼的同源序列进行重组,产生一种能在体外转化原代B淋巴细胞的病毒。该策略对于分析任何基因的部分或全部在细胞生长转化中的作用的分子遗传学研究应是有用的。
