Antiviral activity of IFITM1 induced by H9N2 virus infection in HUVECs and BEAS-2Bs. HUVECs and BEAS-2Bs were infected with H9N2 virus at MOI of 5 and incubated for 1 h, then cells were transfected with control siRNA or IFITM1 specific siRNA for 36 h. Virus titer in each group was detected using plaque assay at 36 h postinfection. The effect of IFIMT1 specific siRNA on IFITM1 expression was detected using western blot. a IFITM1 protein level after transfected with siRNA in HUVECs. b IFITM1 protein level after transfected with siRNA in BEAS-2Bs. c Virus titers in HUVECs transfected with control siRNA or IFITM1 specific siRNA. Compared to virus group (control siRNA), the virus titer in virus + siRNA group (IFITM1 specific siRNA) was increased by 13.1 ± 2.4% (P > 0.05, t-test). d Virus titers in BEAS-2Bs transfected with control siRNA or IFITM1 specific siRNA. Compared to virus group (control siRNA), the virus titer in virus + siRNA group (specific siRNA) was increased by 9.7% ± 3.8% (P > 0.05, t-test)
