Abstract: Objective To study the gene expression profile of human polymeric immunoglobulin receptor gene (hpIgR)-transfected mouse nasopharyngeal epithelial cells transformed with n, n’-dinitrosoperazine (TMNE) before and after EBV infection using cDNA array and investigate the role of Epstein-Barr virus (EBV) infection in the tumorigenesis of nasopharyngeal carcinoma (NPC). Methods The total RNAs of hpIgR-transfected TMNE cells before and after EBV infection were extracted, reversely transcribed, and labeled with α-32P-dATP. The cDNA probes were hybridized to the AtlasTM mouse cancer array 1.2, and the signals analyzed by AtlasImageTM software. Results Twenty-five genes differentially expressed in cells before and after EBV infection, including 23 up-regulated genes and 2 down-regulated genes. Conclusions The gene expression profile of hpIgR-transfected TMNE cells may change after EBV infection, suggesting that these genes are probably involved in the tumorigenesis and progression of NPC.
