Abstract
依據臨床發現,退化性關節炎病人口服葡萄糖胺 (glucosamine HCl) 最後到達血液濃度並不如in vitro實驗研究的有效濃度,卻仍對病人的疼痛及關節修復有一定的效果,因此本實驗使用葡萄糖胺glucosamine HCl來觀察其對於IL-1β誘發chondrosarcoma SW1353細胞間質水解酵素 (Matrix Metallo- proteinase)的影響,發現高劑量的glucosamine HCl可以抑制低濃度IL-1β所引起的MMPs的mRNA及蛋白質表現,也可以抑制IL-8的mRNA表現,並且使用低劑量的glucosamine HCl則可以抑制高濃度IL-1β引起的發炎反應,實驗結果與臨床應用glucosmaine HCl治療關節炎的現象相符。另外,為了更接近關節環境,本實驗另進行正常氧氣濃度與低氧環境的對照,我們發現除了低氧環境會誘導低氧誘導因子 (HIF-1α) 蛋白表現之外,在低氧環境下單純使用IL-1β誘導的MMPs蛋白表現會降低,而且glucosamine HCl抑制MMPs的效果也會更明顯,同時我們也發現軟骨細胞受到IL-1β及低氧環境的誘導,葡萄糖轉移子 (GLUT-1) 表現量上升,依上述結果推論,HIF-1α及GLUT-1可能是glucosamine治療退化性關節炎的重要機制。
