Abstract

We investigated the expression and localization of heme oxygenase-1 (HO-1) in synovial fluid and synovial tissue, and examined the stimulation of HO-1 production in rheumatoid synovial fibroblasts (RASFs). Synovial fluid samples were obtained from knee joints of 20 rheumatoid arthritis (RA) and 20 osteoarthritis (OA) patients, and concentration of HO-1 and matrix metalloproteinase-3 (MMP-3) were measured by enzyme-linked immunosorbent assay (ELISA). Synovial tissues obtained from RA or OA patients during total knee arthroplasty (TKA) were used for immunohistochemical analysis of HO-1. HO-1 production by RASFs in response to various cytokines was examined by ELISA. HO-1 levels in synovial fluid were higher in the RA group than in the OA group with significant difference (P
