Abstract:

BACKGROUND: Matrix metalloproteinase-3 and galectin-3 play important roles in the pathological process of osteoarthritis. There may be some potential relationship between them, but has not been reported.
OBJECTIVE: To detect the expression levels of matrix metalloproteinase-3 and galectin-3 in the synovial tissue of osteoarthritis, and to investigate the roles and relationship between matrix metalloproteinase-3 and galectin-3 in the pathogenesis of osteoarthritis.
METHODS: Synovial tissues were obtained from the 60 patients undergoing total knee arthroplasty or knee arthroscopic treatment surgery and 20 healthy patients suffering from amputation caused by trauma or meniscus or knee ligament injuries caused by acute injury. The informed consents were obtained from all patients, and the study was approved by the Ethics Committee of First Affiliated Hospital of Medical College of Shihezi University. According to the Western Ontario and McMaster Universities Osteoarthritis Index, the osteoarthritis observation group was divided into three groups: mild, moderate, and severe groups, with 20 cases in each group. The expression levels of matrix metalloproteinase-3 and galectin-3 in the synovial tissues were detected by immunohistochemistry, and Pearson correlation analysis was conducted.
RESULTS AND CONCLUSION: (1) Immunohistochemistry results showed that matrix metalloproteinase-3 was positive in 2 (10%) in the non-osteoarthritis group, positive in 7 (35%) samples in the mild-osteoarthritis group, positive in 13 (65%) samples in the medium-osteoarthritis group and positive in 18 (90%) samples in the severe-osteoarthritis group. (2) Galectin-3 was positive in 1 (5%) sample in the non-osteoarthritis group, positive in 6 (30%) samples in the mild-osteoarthritis group, positive in 12 (60%) samples in the medium-osteoarthritis group and positive in 17 (85%) samples in the severe-osteoarthritis group. (3) The expression levels of matrix metalloproteinase-3 and galectin-3 in the synovial tissues presented a positive correlation (r=0.926, P < 0.001), and the levels increased with joint degeneration becoming severe. (4) These results imply that there is a significant increase in the expression levels of matrix metalloproteinase-3 and galectin-3 in the synovial tissues of osteoarthritis compared with the non-osteoarthritis group, and both exert effect in osteoarthritis. Matrix metalloproteinase-3 and galectin-3 play important roles in regulating the process of osteoarthritis and related mutually, thus providing new theoretical direction and experimental basis for targeted gene therapy of osteoarthritis.
