Nasopharyngeal carcinoma (NPC) is a squamous carcinoma, and recent research indicates that EBV in NPC cells exhibits a type II latency infection that expresses viral membrane proteins, such as LMP1, and EBV exists in NPC cells in the form of extrachromosomal circular DNA [34]. The gene discussed is PDLIM7; the disease is nasopharyngeal carcinoma.
