  1. In our laboratory, a unique mutation detection system using a shuttle vector plasmid has been established to demonstrate that a low concentration of mnng ( 0. 2 m ) can induce nontargeted mutation in mammalian cells : the mammalian cells were exposed to 0. 2m mnng for 2. 5h, then a shuttle plasmid pz189 carrying supf trna gene was transfected into cells after 24h culture. we found a 5 - fold higher mutation frequency of the plasmid replicated in pretreated cells than the spontaneous mutation frequency of the plasmid replicated in control cells. this kind of mutation did not occur immediately after mnng exposure

    我們室曾用一特殊的突變檢測系統,直接證明dna損傷劑可在哺乳動物細胞誘發非定標性突變:首先用低濃度( 0 . 2 m )的壽烷化劑mnng (半壽為1 . 1hr )處理細胞2 . 5h后,繼續培養24h ,將重組有用作突變檢測的靶基因supftrna基因的穿梭質粒pz189轉入細胞復制,發現在未受物直接攻擊的穿梭質粒中有較自發突變率高5倍以上的靶基因突變。
