Abstract:
Objective To investigate the effect of high mobility group box chromosomal protein 1 (HMGB-1) on the proliferation and inflammatory phenotype of human fibroblast like synoviocytes (FLS).Methods FLSs were isolated from the synovial tissues of rheumatoid arthritis (RA) patients undergoing joint replacement surgery.All the experiments described here utilize the FLSs between the third and sixth passages.FLS were incubated with HMGB1 at (100,500,2 000 ng/ml) or interleukin (IL)-1β (0.5 ng/ml) or lipopolysaccharide (LPS) (100 ng/ml) alone or HMGB1/IL-1β complexes or HMGB1/LPS complexes.Cell proliferation assay were used by CCK-8,IL-6,IL-8 and matrix metalloproteinase-3 (MMP-3) in culture supernatants were measured using enzyme-linked immunosorbent assays.The measurement data were compared with single factor analysis of variance.Results Stimulation with all concentrations of HMGB1,IL-1β and LPS alone did not affect the cell proliferation of FLS.HMGB1/IL-1β complexes and HMGB1/LPS complexes did not affect the cell proliferation of FLS,neither (F=0.415.P=0.915).Except high concentration of HMGB1 (2 000 ng/ml) could significantly stimulate the secretion of IL-6 from FLS [(23.0±1.1) ng/ml],HMGB1,IL-1β and LPS alone did not affect the production of IL-6,IL-8 and MMP-3.However,HMGB1/IL-1β complexes and HMGB1/LPS complexes increased IL-6,IL-8 and MMP-3 production from FLS (F=97.804,117.383,70.179,P=0.000).Conclusion Neither HMGB1,IL-1β,LPS alone nor HMGB1/IL-1β complexes or HMGB1/LPS complexes affect the cell proliferation of FLS.HMGB1 in complex with LPS or IL-1β boost IL-6,IL-8 and MMP-3 production in synovial fibroblasts from RA patients.
