| 摘 要： | 为了分析猪源新城疫病毒F和HN基因对BHK-21细胞膜的融合作用,采用RT-PCR方法从猪源新城疫病毒JL01株中扩增获得了F蛋白基因,并根据GenBank上登录的猪源新城疫病毒HN基因序列,合成了HN基因,分别将F和HN基因克隆到pKS载体上。又从大肠杆菌BL21（DE3）中扩增得到T7RNA聚合酶基因,将报告基因EGFP与T7RNA聚合酶基因一起定向克隆到痘苗病毒转移载体pSTK上。再将pKS-F、pKS-HN与pSTK-T7-EGFP共转染BHK-21细胞,转染后16h,用Giemsa染液进行染色,可见明显的细胞融合现象。该研究证明猪源新城疫病毒JL01株的F和HN蛋白共同作用于BHK-21细胞使细胞膜融合。 |

| Abstract: | To investigate the effect of expressing F and HN genes of swine Newcastle disease virus JL01 strain on BHK-21 cell fusion,we got F gene from swine Newcastle disease virus by RT-PCR,and synthesized HN gene according to swine Newcastle disease virus HN gene sequence from the GenBank.And then the F and HN genes were inserted into the pKS vector,respectively.T7 RNAP gene was amplified from E.coli BL21(DE3),and along with the EGFP gene was inserted into pSTK vector to construct recombinant plasmid pSTK-T7-EGFP.pKS-F,pKS-HN and pSTK-T7-EGFP were co-transfected into BHK-21 cells.16 h after transfection,the transfected cells showed significant cell fusion by Giemsa staining.This study laid a foundation for study on F and HN gene of swine Newcastle disease virus. |
