| Research Abstract |
Association of Epstein-Barr virus (EBV) with nasopharyngela carcinoma is know. However, mechanism of nasopharyngeal carcinogenesis is not clarified yet. In the present study, we showed that EBV latent membrane protein 1 (LMP1), a viral oncoprotein, induced a cellular morphorogical change as well as epithelial-mesenchymal transition through transcription factors including Twist and snail in nasopharyngeal epithelial cells. Furthermore, comparison of expression of ABCG2, Nanog, Nestin, Oct4, KLF4 and c-Myc between cells with and without LMP1 expression revealed that LMP1 induced cancer stem/progenitor-like cells in nasopharyngeal epithelial cell lines.
