Subsequently, the expression of the viral genome in non-keratinising NPC has been studied extensively in areas with NPC epidemic [14], [16], [27] and major types of viral expression proteins have been found, e.g., EBNA1 [28]–[30], LMP1 [15], [31]–[34] and LMP2A [31]. The gene discussed is PDLIM7; the disease is nasopharyngeal carcinoma.
