Figure 7From: Nuclear localization of Newcastle disease virus matrix protein promotes virus replication by affecting viral RNA synthesis and transcription and inhibiting host cell transcriptionEffect of AHR knockdown on the viral RNA synthesis and viral replication. The expression levels of AHR protein in BSR-T7/5 cells infected with rSS1GFP and rSS1GFP-M/NLSm (A) or transfected with pCI-M and pCI-M/NLSm (B) were examined by Western blotting. The relative levels of the AHR protein were compared with the control GAPDH expression. C Effect of the AHR siRNA or control siRNA on the expression of endogenous AHR in BSR-T7/5 cells. D AHR siRNA- or control siRNA-treated BSR-T7/5 cells were infected with rSS1GFP and rSS1GFP-M/NLSm, and viral RNA synthesis corresponding to the NP and P genes were detected by qRT-PCR. E The growth kinetics of rSS1GFP and rSS1GFP-M/NLSm were compared using multicycle growth curves in AHR siRNA- or control siRNA-treated cells. Error bars represent standard deviations (mean ± SD) (*P < 0.05; **P < 0.01; ***P < 0.001 compared to the value of rSS1GFP-M/NLSm).Back to article page
