PDLIM7 and nasopharyngeal carcinoma: Since this gene set consists of cellular genes that are more down-regulated in NPC tumors with high-level LMP1 compared to NPC tumors with low level or no LMP1 expression [38], this result suggests that a number of the down-regulated cellular genes in EBV-infected versus uninfected NOKs cells may be due to LMP1 expression.
