PEDV infection results in the activation of Caspase-3 and Caspase-8,but not Caspase-9. The activation of Caspase-3, Caspase-8 and Caspase-9 were detected by the Caspase activity assay kits. The relative fold change (OD405nm) of Caspase-3, − 8 and − 9 activities are shown with graphs. Data are represented as mean + /− SD, n = 3.(***, p < 0.001;ns,no significant)
