Overexpression of IFITM1 significantly reduced virus titers in HUVECs and BEAS-2Bs. HUVECs and BEAS-2Bs were transfected with control plasmid (Control) or IFITM1 CRISPR activation plasmid (plasmid) for 36 h, then cells were infected with H9N2 virus at MOI of 5. Virus titer of each group was detected by plaque assay at 36 h postinfection. The overexpression of IFIMT1 was detected by western blot. a IFITM1 protein level after transfected with plasmid in BEAS-2Bs. b IFITM1 protein level after transfected with plasmid in HUVECs. c Virus titers in BEAS-2Bs transfected with control plasmid or IFITM1 CRISPR activation plasmid. Compared to control group (control plasmid), the virus titer in plasmid group (IFITM1 CRISPR activation plasmid) was decreased by 55.72.5 ± 7.53% (P < 0.01, t-test). d Virus titers in HUVECs transfected with control plasmid or IFITM1 CRISPR activation plasmid. Compared to control group (control plasmid), the virus titer in plasmid group (IFITM1 CRISPR activation plasmid) was decreased by 52.76 ± 1.02% (P < 0.01, t-test). * means control group compared with plasmid group (**, P < 0.01, t-test)
