For exploring transcriptional expression of viral genes in the EBV-positive malignancies, we focused on the CST/BART, LF3/IR4 and BARF1 genes – since these were often found expressed with high frequency in EBV-associated carcinomas (Hitt et al, 1989; Xue et al, 2000) – and the membrane functions, LMP1 and 2A, expressed in some of these malignancies, as well as the gene for the nuclear antigen, EBNA1, essential for the maintenance of EBV in cells (IARC, 1997), but expressed at low levels. This evidence concerns the gene PDLIM7 and carcinoma.
