Abstract

Background/aims Scarring and contraction of the conjunctiva are common complications of many ocular diseases. We investigated the effects of all-trans-retinoic acid (ATRA) on the contractility of human Tenon's capsule fibroblasts (HTFs) cultured in a three-dimensional collagen gel. Methods HTFs were cultured in a three-dimensional gel of type I collagen and in the absence or presence of transforming growth factor (TGF)-ß, ATRA, or an inhibitor of matrix metalloproteinases (MMPs). Collagen gel contraction was evaluated by measurement of gel diameter. The release of MMPs and tissue inhibitors of metalloproteinases (TIMPs) into culture supernatants was assessed by immunoblot analysis and gelatin zymography. The release of lactate dehydrogenase activity from HTFs was measured with a colorimetric assay kit. Results ATRA inhibited TGF-ß-induced collagen gel contraction mediated by HTFs in a concentration-and timedependent manner. TGF-ß induced the release of MMP-1, MMP-2 and MMP-3 by HTFs, and ATRA inhibited these effects of TGF-ß on MMP-1 and MMP-3 release. ATRA also stimulated TIMP-1 release from HTFs in the presence of TGF-ß. Furthermore, TGF-ß-induced collagen gel contraction was blocked by the MMP inhibitor GM6001. ATRA did not exhibit cytotoxicity for HTFs. Conclusions ATRA inhibited TGF-ß-induced collagen gel contraction mediated by HTFs, likely in part by attenuating the production of MMP-1 and MMP-3 and by stimulating the production of TIMP-1. ATRA may therefore prove to be of clinical value.
