Osteoarthritis (OA) is a chronic joint-degeneration disease and accounts for the most frequent arthritis in aging people. OA is characterized by the degeneration of articular cartilage, subchondral bone sclerosis and synovitis. Inflammation as an important role in OA progression, in that anti-inflammatory agents could effectively inhibit the development of OA with minimal side effects, therefore developing a nature anti-inflammatory compound will be a promising therapy for treating OA.We treated patient-derived chondrocytes and mouse models of OA with astragaloside, an effective component of, and measured its effect on pro-inflammatory cytokines and OA progression in mice., astragaloside induced a dose-dependent inhibition of IL-1β-induced the production of inflammatory factors, including interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), nitric oxide (NO), prostaglandin E2 (PGE2), expression of MMP 13 and ADAMTS-5, and the activation of NF-κB signaling., astragaloside ameliorate the degeneration of cartilage in mouse model of OA.Astragaloside potentially serve as a promising and effective therapeutic agent for treating OA patients.
