Outline of Final Research Achievements |
In this study, we focused on the EMC-degrading enzymes that are important for osteoarthritis, and sought to find compounds that can inhibit the destruction of cartilage matrix by inhibiting the synthesis of EMC-degrading enzymes. We screened 400 kinds of pilot libraries provided by RIKEN. Results of examining the effect of suppressing the expression of ECM-degrading enzymes compound X significantly suppressed the mRNA expression of four extracellular matrix degrading enzymes such as MMP3, MMP13, ADAMTS4, and ADAMTS9, which were induced by inflammation caused by the inflammatory cytokine IL-1β. It also significantly suppressed the expression of the enzyme COX2, which has a role in promoting inflammation. It was considered that compound X may be effective in treating OA.

Academic Significance and Societal Importance of the Research Achievements |
変形性関節症(OA)は過度の力学的ストレスや加齢変化によって,関節破壊が生じる慢性炎症性疾患である。軟骨が消失することで疼痛や可動域制限等が生じ,患者の生活の質を著しく低下させるため,社会的にも重要な課題である。しかし,有力な治療法に乏しく,痛み止めなどの対症療法にとどまっている。今本研究では400の化合物ライブラリーをOUMS-27(軟骨肉腫)に添加し、細胞外基質分解酵素のMMP-13及びADAMTS4.9, COX-2のmRNA発現量をリアルタイム定量PCR法及びwestern blot法にて検討した。スクリーニング検索を行った結果、有力な候補化合物を3つ決定した。
