After transfection with either GADD45A‐RNAi or Control‐RNAi and subsequent PPRV infection, we found that GADD45A knockdown led to reduced levels of PPRV N protein (Figure 1H; p < 0.05), lower genome copy numbers (Figure 1I; p < 0.01), and decreased viral titers (Figure 1J; p < 0.01). This evidence concerns the gene GADD45A and infection.
