Abstract

Based on the NSP4 sequence of bovine rotavirus (BRV), the shRNA was designed and synthesized, and a shRNA recombinant lenti-virus vector RNAi-H1-89 was constructed. The recombinant RNAi-H1-89 Lenti-virus was packaged by transfecting the 293T cell with the recombinant vector RNAi-H1-89 and two helper plasmids using lipofectamine, and then used to infect MA104 cells. The MA104 cells were further infected with BRV strain G6 24h post-infection, with the LacZ shRNA recombinant lenti-virus as control. Thirty-six hours later, the CPE of the infected cells was observed under microscope, shRNA of NSP4 gene inhibited CPE in MA104 cell; the shRNA against NSP4 gene also inhibited NSP4 gene expression by RT-PCR, The virus titer in the cell culture supernatant was significant lower compared with the control group. The above results showed that RNAi-H1-89 against NSP4 gene could specifically silence NSP4 gene expression, and inhibit the proliferation of BRV.
