[Construction of nasopharyngeal carcinoma CNE-2 cell lines expressing stable fusion suicide gene CD/UPRT. UL49].

OBJECTIVE: To construct nasopharyngeal carcinoma CNE-2 cell lines expressing stable fusion suicide gene CD/UPRT. UL49. METHOD: The plasmids of pcDNA3.1 (-)E6. BARF1p. CD/UPRT. UL49 was transfected into CNE-2 cells through lipofectamine, and the transfected CNE-2 cells were selected by G418 and prodrugs for getting the cells expressing fusion CD/UPRT. UL49 gene. The protein produced by the suicide gene was tested by Western-blotting in CNE-2 cells. RESULT: Suicide genes were expressed stably in CNE-2 cells. CONCLUSION: We constructed nasopharyngeal carcinoma cell lines CNE-2 expressing stable suicide gene through lipofectamine.
