Enhancement of PRRSV replication by ILF2 knockdown in MARC-145 cells. a MARC-145 cells were transfected with different concentrations of siRNAs targeting ILF2 (SiILF2) and the silencing efficiency of ILF2 was examined by western blotting with an anti-ILF2 mAb. The quantity of β-actin was used for normalization of the amount of ILF2 expression. The optical density ratios of ILF2/β-actin are shown with graphs. MARC-145 cells transfected with SiILF2 or negative control siRNA (SiNC), and normal MARC-145 cells, were infected with PRRSV JXwn06 at a MOI of 0.01. The silencing efficiency (b) and the virus titers were examined (c) at the indicated time points post-infection. Data are expressed as means ± SD of three independent experiments (*p < 0.05; ** p < 0.01; *** p < 0.001; ns, no significant)
