We molecularly cloned and analyzed an N-tropic ecotropic retrovirus induced with iododeoxyuridine from RFM/Un mouse cell cultures. Based on the restriction map, the RFM/Un virus appears to be indistinguishable from other induced N-tropic retroviruses. A nucleotide sequence analysis of the long terminal repeat of an infectious clone revealed structural features characteristic of murine type C retrovirus long terminal repeats. The U3 region of the RFM/Un virus long terminal repeat, however, contained no short sequence duplication or insertion found in other murine leukemia virus isolates.
我们从RFM/Un小鼠细胞培养物中,通过碘脱氧尿苷诱导分子克隆并分析了一种N-嗜性亲嗜性逆转录病毒。根据限制酶切图谱,RFM/Un病毒似乎与其他诱导的N-嗜性逆转录病毒没有区别。对一个感染性克隆的长末端重复序列进行核苷酸序列分析,揭示了鼠C型逆转录病毒长末端重复序列的结构特征。然而,RFM/Un病毒长末端重复序列的U3区域,在其他鼠白血病病毒分离株中未发现短序列重复或插入。
