摘要 目的 :研究尿激酶型纤溶酶原激活剂 (urokinase typeplasminogenactivator ,uPA)和它的受体 (uPAR)、抑制剂 (PAI- 1)在具有不同转移率的鼻咽癌细胞系CNE 2Z(2 0 %淋巴道转移 )、CNE 2Z H5 (40 %淋巴道转移 )、CNE 2Z H5 9(90 %淋巴道转移 )中的表达。方法 :应用逆转录聚合酶反应 (RT PCR)方法检测uPA ,uPAR ,PAI 1在基因转录水平的表达。结果 :uPA ,uPARmRNA在CNE 2Z H5 9中表达最高 ,在CNE 2Z中表达最低 ;PAI 1mRNA在CNE 2Z H5 9中无表达 ,在CNE 2Z ,CNE 2Z H5有表达 ,但差异无显著性。结论 :uPA、uPAR可能促进鼻咽癌细胞侵袭、转移 ,PAI 1可能起抑制作用。 Purpose:To study the expression of uPA, uPAR ,PAI 1 in 3 nasopharyngeal carcinoma cell lines CEN 2Z,CEN 2Z H5,CEN 2Z H5 9,with different ability to metastasize through lymph.Methods:RT PCR was used to detect expression of uPA,uPAR,PAI 1 at levels of mRNA.Results:mRNA expression of uPA,uPAR was the highest in CNE 2Z H5 9,whereas the lowest in CNE 2Z;mRNA expression of PAI 1was detected in CNE 2Z and CNE 2Z H5, but revealed no differences,but not in CNE 2Z H5 9.Conclusions:uPA?uPAR may promote the metastasis and invasion of NPC,whereas PAI 1 maybe inhibit it
