Measuring the expression of latent EBV genes in NPC and normal nasopharyngeal tissue samples, it was shown that deregulation of key proteins involving in apoptosis (bcl-2 related protein A1 and Fas apoptotic inhibitory molecule), cell cycle checkpoints (AKIP, SCYL1 and NIN) and metastasis (matrix metalloproteinase 1) were closely correlated with the levels of EBV gene expression in NPC [77]. The gene discussed is AURKAIP1; the disease is nasopharyngeal carcinoma.
