Establishment of nasopharyngeal carcinoma (NPC) cell lines stable expressing NPC-derived LMP1

目的 :建立稳定表达鼻咽癌 (NPC)来源潜伏膜蛋白 1(LMP1)的鼻咽癌细胞系。方法 :利用基因重组技术构建NPC来源LMP1的一般性真核表达载体及上皮特异性表达载体 ,并将其转染鼻咽癌细胞系CNE - 2 ,用PCR、RT -PCR及蛋白印迹等检测N -LMP1在CNE - 2中的整合和表达。结果 :①成功构建了N -LMP1的一般性和上皮特异性表达载体。②N -LMP1基因在CNE - 2细胞中获得了正确表达。结论 :成功建立了稳定表达NPC来源LMP1的鼻咽癌细胞系 ,为进一步研究LMP1在鼻咽癌细胞中的作用机制奠定基础。

AIM: To establish nasopharyngeal carcinoma(NPC) cell lines stable expressing NPC-derived latent membrane protein 1(LMP1) gene. METHODS: General expression vector and epithelium-specific expression vector of NPC-derived LMP1 gene were constructed by using recombinant techniques, then transfected these vectors into a poor differentiated NPC cell line named CNE-2 ,integration and expression of N-LMP1 in CNE-2 cells were detected by PCR,RT-PCR and Western blot. RESULTS: (1) General expression vector and epithelium-specific expression vector of NPC-derived LMP1 gene were constructed successfully.(2) It showed that N-LMP1 gene expressed in CNE-2 cells correctly. CONCLUSION: The first NPC cell lines which stable express NPC-LMP1 were established. The cell lines obtained will provide important basis for exploring the role of NPC-LMP1 in nasopharynx carcinogenesis.
