PG - 5147-5161 LID - 10.1002/jcp.30221 [doi] AB - Endothelial-to-mesenchymal transition (EndMT) and fibroblast-to-myofibroblast (FibroMF) differentiation are frequently reported in organ fibrosis. Stromelysin1, a matrix metalloprotease-3 (MMP3) has been indicated in vascular pathologies and organ injuries that often lead to fibrosis. In the current study, we investigated the role of stromelysin1 in EndMT and FibroMF differentiation, which is currently unknown. In our results, whereas TGFbeta2 treatment of endothelial cells (ECs) induced EndMT associated with increased expression of stromelysin1 and mesenchymal markers such as alpha-smooth muscle actin (alphaSMA), N-cadherin, and activin linked kinase-5 (ALK5), inhibition of stromelysin1 blunted TGFbeta2-induced EndMT. In contrast, treatment of NIH-3T3 fibroblasts with TGFbeta1 promoted FibroMF differentiation accompanied by increased expression of alphaSMA, N-cadherin, and ALK5. Intriguingly, stromelysin1 inhibition in TGFbeta1-stimulated myofibroblasts further exacerbated fibroproliferation with increased FibroMF marker expression. Gene Expression Omnibus (GEO) data analysis indicated increased stromelysin1 expression associated with EndMT and decreased stromelysin1 expression in human pulmonary fibrosis fibroblasts. In conclusion, our study has identified that EndMT and FibroMF differentiation are reciprocally regulated by stromelysin1. CI - (c) 2020 Wiley Periodicals LLC.
