| 4 | High Level Expression of Grass Carp Reovirus VP7 Protein in Prokaryotic Cells显示文摘Sequences analysis revealed Grass carp reovirus (GCRV) s10 was 909 nucleotides coding a 34 kDa protein denoted as VP7, which was determined to be a viral outer capsid protein (OCP). To obtain expressed OCP in vitro, a full length VP7 gene was produced by RT-PCR amplification, and the amplified fragment was cloned into T7 promoted prokaryotic expression vector pRSET. The recombinant plasmid,which was named as pR/GCRV-VP7,was then transformed into E.coli BL21 host cells. The data indicated that the expressed recombinant was in frame with the N-terminal fusion peptide. The over-expressed fusion protein was produced by inducing with IPTG, and its molecular weight was about 37kDa, which was consistent with its predicted size. In addition, the fusion protein was produced in the form of the inclusion body with their yield remaining steady at more than 60% of total bacterial protein. Moreover,the expressed protein was able to bind immunologically to anti-his-tag monoclonal antibody (mouse) and anti-GCRV serum (rabbit). This work provides a research basis for further structure and function studies of GCRV during entry into cells. | Lan-lan ZHANG Jin-yu SHEN Cheng-feng LEI Xiao-ming LI Qin FANG | 2008 | Virologica Sinica2008，23，1： | 14 |

| 12 | Antigenic analysis of grass carp reovirus using single-chain variable fragment antibody against IgM from Ctenopharyngodon idella显示文摘Grass carp (Ctenopharyngodon idella) is an important species of freshwater aquaculture fish in China. However, grass carp reovirus (GCRV) can cause fatal hemorrhagic disease in yearling populations. Until now, a strategy to define the antigenic capacity of the virus's structural proteins for preparing an effective vaccine has not been available. In this study, some single-chain variable fragment antibodies (scFv), which could specifically recognize grass carp IgM, were selected from a constructed mouse na ve antibody phage display cDNA library. The identified scFv C1B3 clone was shown to possess relatively higher specific binding activity to grass carp IgM. Furthermore, ELISA analysis indicated that the IgM level in serum from virus-infected grass carp was more than two times higher than that of the control group at 5-7 days post infection. Moreover, Western blot analysis demonstrated that the outer capsid protein VP7 has a specific immuno-binding-reaction with the serum IgM from virus-infected grass carp. Our results suggest that VP7 can induce a stronger immune response in grass carp than the other GCRV structural proteins, which implies that VP7 protein could be used as a preferred immunogen for vaccine design. | CHEN CongLin SUN XiaoYun LIAO LanJie LUO ShaoXiang LI ZhouQuan ZHANG XiaoHua WANG YaPing GUO QionLin FANG Qin DAI HePing | 2013 | Science China(Life Sciences)2013，56，1： | 6 |

| 15 | Expression of Outer Capsid Protein VP5 of Grass Carp Reovirus in E.coli and Analysis of its Immunogenicity显示文摘Grass carp reovirus (GCRV) is a tentative member of the Aquareovirus genus in the family Reoviridae. The mature virion comprises 11 dsRNA genomes enclosed by two concentric icosahedral proteins shells that is comprised of five core proteins and two outer capsid proteins. The genome sequence and 3D structure demonstrate there is a higher level of sequence homology in structural proteins between GCRV and mammalian orthoreoviruses (MRV) compared to other members of the family. To understand the pathogenesis of GCRV infection, the outer capsid protein VP5, a homology of the μ1 protein of MRV, was expressed in E.coli. It was found that the recombinant VP5 was highly expressed, and the expressed His-tag fusion protein was involved in the formation of the inclusion body. Additionally, specific anti-VP5 serum was prepared from purified protein and western blot demonstrated that the expressed protein was able to bind immunologically to rabbit anti GCRV particle serum and the immunogenicity was determined by ELISA assay. Additional experiments in investigating the functional properties of VP5 will further elucidate the role of the GCRV outer capsid protein VP5 during entry into host cells, and its interaction among viral proteins and host cells during the infection process. | Lan-lan ZHANG Jin-yu SHEN Cheng-feng LEI Chao FAN Gui-jie HAO Qin FANG | 2009 | Virologica Sinica2009，24，6： | 5 |
| 16 | The VP2 protein of grass carp reovirus(GCRV) expressed in a baculovirus exhibits RNA polymerase activity显示文摘The double-shelled grass carp reovirus(GCRV) is capable of endogenous RNA transcription and processing. Genome sequence analysis has revealed that the protein VP2, encoded by gene seg-ment 2(S2), is the putative RNA-dependent RNA polymerase(RdRp). In previous work, we have ex-pressed the functional region of VP2 that is associated with RNA polymerase activity(denoted as rVP2390-900) in E. coli and have prepared a polyclonal antibody against VP2. To characterize the GCRV RNA polymerase, a recombinant full-length VP2(rVP2) was first constructed and expressed in a baculovirus system, as a fusion protein with an attached His-tag. Immunofluorescence(IF) assays, together with immunoblot(IB) analyses from both expressed cell extracts and purified His-tagged rVP2, showed that rVP2 was successfully expressed in Sf9 cells. Further characterization of the replicase activity showed that purified rVP2 and GCRV particles exhibited poly(C)-dependent poly(G) polymerase activity. The RNA enzymatic activity required the divalent cation Mg2+, and was optimal at 28 °C. The results provide a foundation for further studies on the RNA polymerases of aquareoviruses during viral transcription and replication. | Liming Yan Huan Liu Xiaoming Li Qin Fang | 2014 | Virologica Sinica2014，29，2： | 4 |

| 18 | Expression and Identification of Inclusion Forming-related Domain of NS80 Nonstructural Protein of Grass Carp Reovirus显示文摘Grass carp reovirus(GCRV),a double stranded RNA virus that infects aquatic animals,often with disastrous effects,belongs to the genus Aquareovirus and family Reoviridea. Similar to other reoviruses,genome replication of GCRV in infected cells occurs in cytoplasmic inclusion bodies,also called viral factories. Sequences analysis revealed the nonstructural protein NS80,encoded by GCRV segment 4,has a high similarity with μNS in MRV(Mammalian orthoreoviruses) ,which may be associated with viral factory formation. To understand the function of the μNS80 protein in virus replication,the initial expression and identification of the immunogenicity of the GCRV NS80 protein inclusion forming-related region(335-742) was investigated in this study. It is shown that the over-expressed fusion protein was produced by inducing with IPTG at 28oC. In addition,serum specific rabbit antibody was obtained by using super purified recombinant NS80(335-742) protein as antigen. Moreover,the expressed protein was able to bind to anti-his-tag monoclonal antibody(mouse) and NS80(335-742) specific rabbit antibody. Further western blot analysis indicates that the antiserum could detect NS80 or NS80C protein expression in GCRV infected cells. This data provides a foundation for further investigation of the role of NS80 in viral inclusion formation and virion assembly. | Chao FAN Lan-lan ZHANG Cheng-feng LEI Qin FANG | 2009 | Virologica Sinica2009，24，3： | 4 |
