%0 Journal Article %T Isolating the cDNA fragment inhibiting nontargeted mutagenesis in vero cell by antisense technology %A Wenwei Hu %A Yingnian Yu %A Xingruo Chen %A Tao Song %A Haiyang Xie %J Chinese Science Bulletin %@ 1861-9541 %D 1999 %I %R 10.1007/BF02885542 %X Among the expressed sequence tags (ESTs) which were isolated from genetically instable monkey kidney vero cells induced by N-methyl-N¡ä-nitro-N-nitrosoguanidine (MNNG), a fragment 9 was isolated. When the expression of fragment 9 was blocked through transcripting antisense RNA, MNNG-induced nontargeted mutation frequency enhanced significantly compared with control (P< 0.05). The result showed that the relevant gene of fragment 9 might participate in maintaining cellular genetic stability and be involved in inhibition of nontargeted mutagenesis. %K antisense RNA %K mutation %K nontargeted %K genetic instability %U http://link.springer.com/article/10.1007/BF02885542
