ABSTRACT
BACKGROUND/OBJECTIVES: We investigated the anti-osteoarthritic effects of deer bone extract on the gene expressions of matrix metalloproteinases (MMPs) and collagen type II (COL2) in interleukin-1β-induced osteoarthritis (OA) chondrocytes. MATERIALS/METHODS: Primary rabbit chondrocytes were treated as follows: CON (PBS treatment), NC (IL-1β treatment), PC (IL-1β + 100 µg/mL glucosamine sulphate/chondroitin sulphate mixture), and DB (IL-1β + 100 µg/mL deer bone extract). RESULTS: The results of the cell viability assay indicated that deer bone extract at doses ranging from 100 to 500 µg/mL inhibits cell death in chondrocytes induced by IL-1β. Deer bone extract was able to significantly recover the mRNA expression of COL2 that was down-regulated by IL-1β (NC: 0.79 vs. DB: 0.87, P < 0.05) and significantly decrease the mRNA expression of MMP-3 (NC: 2.24 vs. DB: 1.75) and -13 (NC: 1.28 vs. DB: 0.89) in OA chondrocytes (P < 0.05). CONCLUSIONS: We concluded that deer bone extract induces accumulation of COL2 through the down-regulation of MMPs in IL-1β-induced OA chondrocytes. Our results suggest that deer bone extract, which contains various components related to OA, including chondroitin sulphate, may possess anti-osteoarthritic properties and be of value in inhibiting the pathogenesis of OA.
