In the present study, it was observed that the EBV-LMP1 expression intensity and EBER-1 hybridization in the renal tissue samples were weaker than those in the NPC tissues (the positive controls) under the same experimental conditions, which suggested that the number of copies of EBV in the renal tissues was lower than that in the NPC tissues. The gene discussed is PDLIM7; the disease is nasopharyngeal carcinoma.
