Several reports have demonstrated that BARF1 is expressed in the tissues of various EBV-associated epithelioid malignancies. However,BARF1 is thought to be a lytic gene, since its expression is induced upon induction of the lytic cycle in Burkitt's lymphoma cell lines. Therefore, the possibility cannot be excluded that BARF1 expression in EBV-associated epithelioid malignancies reflects spontaneous induction of the lytic cycle in carcinoma cells. The present study aimed to clarify whether BARF1 was expressed as a latent gene or a lytic gene in epithelioid malignancies. Quantitative real-time RT-PCR assay revealed that BARF1 was highly expressed in nasopharyngeal carcinoma (NPC) and EBV-positive gastric carcinoma tissues in the absence of expression of lytic genes. On the other hand, BARF1 protein was detectable only in two of seven NPC tissue samples by immunoblot analysis. Analysis of BARF1-transfected CNE1 cells revealed that BARF1 was quickly secreted into culture medium and was hardly detectable in the cell lysate, which would account for why some NPC tissues were negative for BARF1 protein expression even though they were strongly positive forBARF1 expression at the transcriptional level. The present findings indicate that BARF1 is expressed in NPC and EBV-positive gastric carcinoma tissues as a latent gene and suggest that BARF1 plays a role in the pathogenesis of these malignancies."xsd:string |
