ABSTRACT
ObjectiveTo understand the possible role of some proteins expressed by human synovial fibroblasts(SFs)in the pathogenesis of rheumatoid arthritis.MethodsThe expression difference of synovial fibroblast proteins between rheumatoid arthritis(RA)patients and healthy controls was analyzed by 2-DE.The differential expression spots were identified by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry(MALDI-TOF-MS),followed by bioinformatics analysis,some of which were validated by Western blot.ResultsUsing 12% SDS-PAGE following pH 4-7 IPG strips in IEF,averagely 837 and 852 protein spots were detected in RA patients and normal subjects,respectively.Gel image analysis revealed that there were 49 differential protein spots.By peptide mass fingerprinting strategy,we identified 40 protein spots derived from gels of SFs in RA patients among differential spots and 23 valid proteins were obtained.Western blot analysis showed that expressions of Enolase ?,Annexin I,Cathepsin D,SOD2,Peroxiredoxin 2 were significantly higher in SFs from RA patients than those from normal subjects,which was consistent with proteome analysis.ConclusionThe differential proteins might be involved in inflammation of synovitis in RA.
