In
addition, 12 differentially expressed genes (DEGs) were validated by quantitative PCR. These DEGs were
involved in many pathways of viral pathogenesis. Further analysis of the major DEGs genes involved in
the RLRs and apoptosis pathways revealed some interesting findings. In the RLRs pathway, ISKNV
infection inhibited the activation of NF-kB via over expression of the IKKB-a and IKKB-b and lessened
expression of interleukin-1 receptor-associated kinase 4 (IRAK4). In the apoptosis pathway, ISKNV
infection could induce apoptosis mainly via tumor necrosis factor (TNF) mediated extrinsic pathway. The
cellular apoptosis induced by ISKNV infection was confirmed using annexinV-FITC/PI and DAPI staining
methods.
