Establishment of a low-tumorigenic MDCK cell line and study of differential molecular networks.

Influenza is an acute respiratory infection caused by the influenza virus, and vaccination against influenza is considered the best way to prevent the onset and spread. MDCK (Madin-Darby canine kidney) cells are typically used to isolate the influenza virus, however, their high tumorigenicity is the main controversy in the production of influenza vaccines. Here, MDCK-C09 and MDCK-C35 monoclonal cell lines were established, which were proven to be low in tumorigenicity.

[Tandem expression of the major epitope domains of the Moschus chrysogaster hemorrhagic disease virus VP60 and its protective efficacy to rabbits].

Moschus chrysogaster (sifanicus) viral hemorrhagic disease (McVHD) is an acute and highly lethal infectious disease caused by Moschus chrysogaster hemorrhagic disease virus (McHDV) whose genome sequence is highly homologous with rabbit hemorrhagic disease virus. To screen the protective antigen of McHDV and set the basis for study of McVHD vaccine, the antigen epitope of major structural protein VP60 of McHDV was analyzed, and the specific primers were designed to obtain three amplified DNA sequences encoding the main antigen epitope of VP60 from McHDV by using RT-PCR. Then the three DNA fragments were sequenced and cloned to prokaryotic expression vector with pET-28a(+) by using overlap extension PCR, and finally the prokaryotic expression plasmid pET-truncated-VP60 was constructed.
