PRV infection activated the MAPK signaling in porcine granulosa cells. The expression of three major MAPKs family members-ERK, p38 and JNK was detected in porcine granulosa cells following PRV infection with PRV at titers 5, 10, 50 TCID₅₀ by Western blot analysis. Representative blot images and quantification for p-p38/p38 (A), p-JNK/JNK (B) and p-ERK/ERK (C). Data were shown as mean ± SEM values of three independent experiments. Significant differences between Mock- and PRV-infection are indicated by * P < 0.05, ** P < 0.01
