NPC tumors express three EBV latency type II gene products (LMP-1, LMP-2, EBNA-1), which are found in EBV implicated epithelial cancers, in addition to the expression of viral encoded small RNAs such as EBER and microRNAs (miRNAs) 22, 100, 160. This evidence concerns the gene PDLIM7 and nasopharyngeal carcinoma.
