目的:分析原癌基因 Pim-1在鼻咽癌(nasopharyneal carcinoma,NPC)细胞增殖和迁移中的作用。方法通过 RT-PCR、Western blotting、免疫荧光法检测 NPC 细胞 CNE1、CNE-GL、CNE-2Z、C666-1中 Pim-1的表达,用不同浓度的 Pim-1特异性抑制剂---六羟黄酮(quercetagetin)处理 CNE1、CNE1-GL、C666-1细胞系,检测细胞的活力、克隆形成率、迁移能力。结果高分化的 CNE1细胞中 Pim-1的表达为阴性,低分化的 CNE-2Z 细胞为弱阳性,而未分化的 C666-1细胞为强阳性。CNE1-GL 细胞和 C666-1细胞在用六羟黄酮处理后显著抑制了细胞的活力、克隆形成率、迁移能力。CNE1-GL 细胞来源于 CNE1细胞,用 EP 病毒潜在膜蛋白-1(LMP-1)过表达质粒转染后,显著促进了Pim-1的表达,过表达而 CNE1细胞未受到抑制。结论这些结果表明,Pim-1的表达是反应 NPC 的增殖和迁移的一种重要标志物,靶向与 Pim-1的药物或许可以用于治疗 Pim-1过表达的 NPC 患者。
目的:分析原癌基因 Pim-1在鼻嚥癌(nasopharyneal carcinoma,NPC)細胞增殖和遷移中的作用。方法通過 RT-PCR、Western blotting、免疫熒光法檢測 NPC 細胞 CNE1、CNE-GL、CNE-2Z、C666-1中 Pim-1的錶達,用不同濃度的 Pim-1特異性抑製劑---六羥黃酮(quercetagetin)處理 CNE1、CNE1-GL、C666-1細胞繫,檢測細胞的活力、剋隆形成率、遷移能力。結果高分化的 CNE1細胞中 Pim-1的錶達為陰性,低分化的 CNE-2Z 細胞為弱暘性,而未分化的 C666-1細胞為彊暘性。CNE1-GL 細胞和 C666-1細胞在用六羥黃酮處理後顯著抑製瞭細胞的活力、剋隆形成率、遷移能力。CNE1-GL 細胞來源于 CNE1細胞,用 EP 病毒潛在膜蛋白-1(LMP-1)過錶達質粒轉染後,顯著促進瞭Pim-1的錶達,過錶達而 CNE1細胞未受到抑製。結論這些結果錶明,Pim-1的錶達是反應 NPC 的增殖和遷移的一種重要標誌物,靶嚮與 Pim-1的藥物或許可以用于治療 Pim-1過錶達的 NPC 患者。

Objective To study the effection of proto oncogene Pim-1 in nasopharyngeal carcinoma cells (Naso-pharyneal,carcinoma,NPC)in the proliferation and migration in vitro.Methods To detection the expression of Pim in NPC cell CNE1,CNE-GL,CNE-2Z,C666-1,Pim-1 RT-PCR,by Western blotting,immunofluorescence.CNE1,CNE1-GL,C666-1 cell line,cell viability,clone formation rate,migration was measured by Using six different concentrations of quercetin (quercetagetin)Pim-1 specific inhibitor-treatment.Results the expression of Pim-1 in the high differentiation in CNE1 cells were negative,low differentiated CNE-2Z cells were weakly positive,and undifferentiated C666-1 cells were strong positive.In the CNE1-GL cells and C666-1 cells six quercetin treatment significantly inhibited the cell via-bility,colony formation rate,migration.CNE1-GL cells derived from CNE1 cells,with EP virus latent membrane protein-1 (LMP-1)expression plasmid transfected,significantly promote the expression of Pim-1,expression of CNE1 cells is not inhibited.Conclusion These results indicate that,the expression of Pim-1 is an important marker of proliferation and migration in NPC,drug targeting and Pim-1 may be used for the treatment of Pim-1 over expression of NPC pa-tients.
