We investigated expression of Epstein-Barr virus (EBV) encoded genes and potentially oncogenic cellular proteins in 38 nasopharyngeal carcinomapatients. 26 subjects were from Sapporo Medical University, and 12 from China Medical University, Shenyang, China. Presence of EBV was determined by in situ hybridization of EBER1. ZEBRA, LMP1, p53, Bcl-2, and c-Myc expressions which were deter-mined by immunohistochemical staining. Positive rates were as follows;EBER1 (87%), ZEBRA (11%), LMP1 (42%), Bc1-2 (63%), p53 (68%), and c-Myc (42%). We compared the positive rate in Sapporo cases with those in Shenyang cases, and discussed about the relationship between the expres-sion of these EBV-encoded genes and cellular pro-teins.
