ABSTRACT
OBJECTIVE@#To compare the proteome difference of nasopharyngeal carcinoma (NPC) cell lines 5-8F and 6-10B, and to screen these proteins associated with NPC metastasis.@*METHODS@#Two-dimensional gel electrophoresis (2-DE) was used to separate the total proteins from NPC cell lines 5-8F and 6-10B with different metastatic potentials and same genetic background, respectively. PDQuest software was applied to analyze 2-DE images, and the differentially expressed protein spots between 5-8F and 6-10B were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The expression levels of partial identified proteins in the 2 cell lines were detected by Western blot.@*RESULTS@#2-DE maps of total proteins from 5-8F and 6-10B were established. A total of 65 differential protein spots in the 2 cell lines were found, and 15 non-redundant differential expression proteins were identified by MALDI-TOF-MS. Western blot showed that Annexin A1 and 14-3-3 protein sigma were differential expression proteins in 5-8F and 6-10B, which was consistent with the Results from the comparative proteomic analysis.@*CONCLUSION@#Fifteen non-redundant differential expression proteins are useful for studying the metastatic mechanism of NPC.
