| 内容記述 | Keratan sulfate is the specific molecule in glycosaminoglycan, which is the matrix of articular cartilage, and is produced by chondrocytes. There is evidence that levels of serum keratan sulfate might reflect turnover of articular cartilage in vivo. To gain more insight into related events, the effects of cytokines and growth factors (interleukin-1, interleukin-6, tumor necrosis factor alfa, transforming growth factor beta (TGF-β), platelet derived growth factor, and insulin like growth factor) on keratan sulfate release in vitro were investigated. All cytokines inhibited keratan sulfate release, whereas growth factors stimulated keratan sulfate release. TGF-β exhibited the most striking effect on keratan sulfate release in the chondrocytes and, this effect was receptor mediated since pretreatment with TGF-β reduced the effect (down-regulation). Actionomycin D and cycloheximide completely blocked the TGF-β mediated keratan sulfate increase. TGF-β enhanced the expression of core protein mRNA. Thus, TGF-β probably enhances keratan sulfate through de novo synthesis. Cytokines and growth factors do appear to regulate keratan sulfate release. With its effects on synthesis of matrix proteins, TGF-β may promote repair in diseased articular cartilage. Moreover, our study indicates that the levels of keratan sulfate in the blood of healthy subjects and in subjects with disease (rheumatoid arthritis, rapidly destructive coxarthropathy and osteoarthritis) may reflect turnover of articular cartilage. | |||||||||
