BACKGROUND: Influenza virus infection is a major threat to human health. Small
interfering RNA (siRNA) is a promising approach for the prevention and treatment
of viral infections. In this study, we constructed a series of DNA vector-based
short hairpin RNAs (shRNAs) that target various genes of the influenza A virus
using the polymerase III U6-RNA promoter to prevent influenza virus infection in
vitro and in a mouse model. RESULTS: Three sets of DNA vector-based shRNA, two
targeting genes encoding the polymerase acidic protein (PA) and one targeting
polymerase basic protein 2 (PB2), efficiently inhibited the replication of
influenza virus A/WSN/33(H1N1) in vitro. We also successfully prevented influenza
virus A/WSN/33(H1N1) infection in a C57BL/6 mouse model by intratracheal delivery
of anti-PB2 shRNA. CONCLUSIONS: Our findings suggest that the PB2-targeting shRNA
plasmid showed potential for use as an RNAi-based therapeutic for influenza virus
infection.
