Objective To study the effect of Epstein-Barr virus(EBV) latent membrane protein 1 (LMP1) gene on proliferation of human nasopharyngeal carcinoma (NPC) cell line CNE1.Methods EBV-LMP1 eukaryotic expression plasmid carried the green fluorescent protein(GFP) report gene and control plasrnid were transfected into CNE1 cells line,respectively,by using electroporation.The proliferation changes of transfectants were measured by cellular proliferation assay.The expression of EBV-LMP1 was detected by immunohistoche...
