The Effect of Heparin on Gene Expression of Collagen, MMP, TGF-β Isoforms Using Cultured Fibroblast from Transverse Carpal Ligament of Carpal Tunnel Syndrome

Purpose: Noninflammatory synovial fibrosis has been noted for main causal factor of carpal tunnel syndrome (CTS). Recently, there are some reports that heparin have not only anti-coagulative effect but also anti-inflammatory and anti-fibrotic potential and have an effect on interstitial pulmonary fiborosis. Authors examined whether heparin affects pathogenesis of CTS. Methods: First, heparin was administered to fibroblast that was cultured from patient's transverse carpal ligament. Secondly, we evaluated the expression from genes of type I, III collagen, TGF ${\beta}$ isoforms and MMP. Fibroblasts were isolated and cultured from transverse carpal ligaments of 5 patients with CTS. Heparin (0, 1, 10,$100{\mu}g/ml$) was administered to cultured fibroblast and reverse transcription PCR for mRNA expression of type I, III collagen, TGF-${\beta}$ isoforms and MMP was done. Results: Heparin suppressed gene expression of type I, III collagen and TGF-${\beta}1$, ${\beta}3$ but promoted gene expression of TGF-${\beta}2$ and MMP-2. Conclusion: Heparin directly suppress gene expression of type I, III collagen. But, It is undetermined that heparin can present it's effect mediated by TGF ${\beta}$ isoforms or MMP.
