Type: article
Abstract: Purpose: To investigate the role of Gremlin-1, which is an endogenous antagonist of the bone morphogenetic protein (BMP) signaling pathway, in inducing epithelium-mesenchymal transition (EMT) in fetal RPE cells after repeated wounds. Methods: . Finally, LDN193189, which is a type of pan-inhibitor of BMP receptors, was used to verify whether complete blocking of the BMP pathway interferes with the redifferentiation in low-passage fetal cells, even if the cells were treated with transforming growth factor beta 1 (TGF-β) inhibitors. Results: was subsequently upregulated. Conclusions: silencing has no effects on the TGF-β pathway. Thus, Gremlin-1 may serve as a novel target to treat proliferative vitreoretinopathy (PVR) and inhibit subretinal fibrosis, which is a risk factor for influencing the therapeutic effects of anti-vascular endothelial growth factor (anti-VEGF) on neovascular age-related macular degeneration (nAMD).
