PDLIM7 and diffuse large B-cell lymphoma: 1994). The main EBV gene products include EBV nuclear antigen (EBNA), latent membrane protein (LMP) and EBV with small RNA (EBER). Most of them are closely associated with the EBV replication, and few gene products are related to the transformation and immortalization of EBV (Geng and Wang 2015; Grywalska and Rolinski 2015). During the latent state, all the gene products have a carcinogenic effect. LMP1, LMP2A, LMP2B and EBNA1 induce malignant transformation of cells and lead to the occurrence of diffuse large B-cell lymphoma (Brown et al. 2001).
