Validation of the microarray data by qRT-PCR analyses. The genes of TAP1, SAA2, C4, CD2, IRG6, TCN1, ISG20, PR39, PMAP23 and NPG4 were up regulated in SwIV infected pigs compared with normal controls; TGFB2, VEGFA, TLR5 were down regulated. Fold change is calculated based on the mean intensity value from 3 pigs by using the comparative Ct method. Significant levels were analyzed by T-test.
