Gene expression profiling, pathway analysis and IPA analysis by comparison of with PNCK-depleted NPC cells with its wild-type cells revealed that hundreds of genes were significantly altered after PNCK knockdown, especially the signaling pathways (i.e., PI3K/AKT/mTOR, IL-1 and integrin signaling) and biological events (i.e., cell deaths and survival, apoptosis, cancer pathogenesis, cellular development). Here, AKT1 is linked to nasopharyngeal carcinoma.
