摘要:

为探究鸡J亚群禽白血病病毒(ALV-J)的致病机理,采用PCR方法分4段分别扩增出J亚群禽白血病病毒安徽分离株AH-J11的前病毒cDNAPCR产物经克隆鉴定,酶切后顺次连接,获得含有完整ALV-J AH-J11株前病毒cDNA的重组质粒,命名为pSK-AH-J11。将AH-J11株全基因序列克隆至pBluescript SK(+)载体中,得到重组质粒pBl-AH-J11,并将其转染鸡胚成纤维细胞(CEF)。通过间接免疫荧光试验,RT-PCRWestern blot检测,并经测序验证比对拯救前后病毒的gp85基因序列,结果均表明拯救出了1株重组J亚群禽白血病病毒(rALV-J)。本研究成功构建了鸡ALV-J的感染性克隆并救获了其重组病毒,为研究禽白血病的致病机理提供了良好的反向遗传操作技术平台。

Abstract:

In order to explore the pathogenesis of subgroup J avian leukosis virus(ALV-J), a full-length infectious clone of ALV-J (pSK-AH-J11) was constructed by combining of four fragments using PCR method from AH-J11 isolated from broiler in Anhui province, then the complete genome was cloned into pBluescript SK(+) vector. The recombinant plasmid pBl-AH-J11 was transfected into chicken embryo fibroblast (CEF) cells and the recombinant ALV-J was rescued. The rescued ALV-J (rALV-J) was identified by RT-PCR, Western blot, indirect immunofluorescence assay and sequence comparision of gp85 gene with AH-J11strain, respectively. The results showed that the recombinant rALV-J was rescued in CEF. This study provides a useful platform for investigation of the pathogenesis and molecular biology of ALV-J.
