The influence of inhibitors sunitinib and erlotinib on NDV F, AP1M1, and AP2M1 protein expression. (a and b) Viral F mRNA expression of cells infected with an NDV containing a wildtype (rSG10*) or mutated (rSG10*-F/Y524A, rSG10*-F/Y527A, or rSG10*-F/Y524AY527A) YLMY motif and treated with sunitinib (a) or erlotinib (b). The cells were infected with NDV at 37 ℃ for 1 h, and then the cells were treated with 1 µm sunitinib or 10 µm erlotinib; DMSO was used as a negative control. The p-values were calculated by a two-way ANOVA; *p <0.05; **p <0.01; ***p <0.001; n = 3. (c and d) the F, AP1M1, and AP2M1 protein expression at 24 hpi (c) or 36 hpi (d) in cells infected with an NDV containing a wildtype (rSG10*) or mutated (rSG10*-F/Y524A, rSG10*-F/Y527A, or rSG10*-F/Y524AY527A) YLMY motif and treated with sunitinib or erlotinib. (e) Quantitative analysis of the viral F and host AP1M1 and AP2M1 protein expression by treatment group (sunitinib, erlotinib, or DMSO). (f) Quantitative analysis of the viral F and host AP1M1 and AP2M1 protein expression by NDV strain (rSG10*, rSG10*-F/Y524A, rSG10*-F/Y527A, or rSG10*-F/Y524AY527A). (g) Virus titre of each treatment group (sunitinib, erlotinib, or DMSO). The virus titer was measured as the tissue culture infective dose by inoculating naive cells with supernatants from infected cells. (h) Virus titer of each NDV strain (rSG10*, rSG10*-F/Y524A, rSG10*-F/Y527A, or rSG10*-F/Y524AY527A). The p-values were calculated by a two-way ANOVA; *p <0.05; **p <0.01; ***p <0.001; n = 3.
