PSMB9 and nasopharyngeal carcinoma: Thus, in latency type 0, only EBERs are synthesized; in type I, only EBERs and EBNA1 (Burkitt lymphoma and gastric carcinoma) are synthesized; in type II, EBERs, EBNA1, LMP1 and LMP2 genes (some types of Hodgkin’s lymphoma, NPC, CAEBV and T/NK lymphomas) are expressed; and in type III, all genes of type II and additionally EBNA2, EBNA3 and EBNA-LP (most cases of PTLD or lymphoblastoid cell lines (LCLs)) are expressed.
