Proteomic Analysis of Differential Protein Expression in Fibroblast-like Synoviocytes of Pig

Proteomic Analysis of Differential Protein Expression in Fibroblast-like Synoviocytes of Pig

The innermost structures of synovium consist of one to three layers of cells generally identified as synovial lining cells(SLC). The present studies were initiated to determine the protein expression patterns of fibroblast-like synovial(FLS) cells derived from the synovia of rheumatoid arthritis. Post-traumatic arthritis(PTA) is one of the most common causes of secondary osteoarthritis, and usually affects younger people. The proteins were separated by two-dimensional polyacrylamide gel electrophoresis and RNA expression investigated by RT-PCR Proteome analyses led to the identification of more than 1,500 protein spots and of 11 differently expressed protein spots among them. Six proteins were down-regulated, and five proteins were up-regulated in ACL-transected synovial tissue. Among these, spots 3 and 8 were identified as cofilin-1 and smooth muscle protein 22-α, respectively, Therefore, the proteome analysis of synovial tissue is a useful approach to investigate a joint after an injury and can be used to understand the pathogenesis of PTA.
