In most if not all NPC tumors, EBV displays type II latency, where EBV-encoded small RNA (EBER), EBV-associated nuclear antigen-1 (EBNA1), latent membrane protein 1/2 (LMP1 and LMP2), and BamHI A rightward transcript (BART)-microRNAs are expressed3,7, while EBV in EBVaGC is found to have latency I or II5. This evidence concerns the gene PDLIM7 and nasopharyngeal carcinoma.
