Abstract:
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
