Gene expression profiles of the JIA and control FLS were obtained using the Affymetrix platform, with application of Ingenuity Pathway Analysis and Gene Set Enrichment Analysis software to define gene sets in dysregulated pathways and networks of potential pathologic relevance in this disease. Biologically relevant differentially expressed genes were confirmed by RNA and protein analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Exploration of global gene expression profiles of the JIA FLS revealed important dysregulated pathways, including the transforming growth factor \u03b2 (TGF\u03b2) signaling, as well as endochondral bone formation, cartilage formation, and \u03b2\u2010catenin networks. Importantly, bone morphogenetic protein 4 (BMP\u20104) was significantly overexpressed in the JIA FLS. FLS from patients with oligoarticular JIA exhibit a chondrocyte phenotype, as evidenced by expression of type II collagen and aggrecan.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Dysregulation of the pathways involved in the pathogenesis of oligoarticular JIA were revealed through gene expression profiling. JIA FLS displayed dysregulated TGF\u03b2 signaling and exhibited a hypertrophic chondrocyte phenotype. These characteristics, along with contributions from the \u03b2\u2010catenin network may have implications for endochondral bone formation and local growth disturbances in oligoarticular JIA. Overexpression of BMP\u20104 in FLS from patients with oligoarticular JIA in particular may play an important role in disease pathogenesis, with a direct effect on functional outcome and with implications for future treatment.<\/jats:p><\/jats:sec>","DOI":"10.1002\/art.38336","type":"journal-article","created":{"date-parts":[[2013,12,24]],"date-time":"2013-12-24T08:20:55Z","timestamp":1387873255000},"page":"1352-1362","source":"Crossref","is-referenced-by-count":32,"title":["The Role of Transforming Growth Factor \u03b2 Signaling in Fibroblast\u2010like Synoviocytes From Patients With Oligoarticular Juvenile Idiopathic Arthritis: Dysregulation of Transforming Growth Factor \u03b2 Signaling, Including Overexpression of Bone Morphogenetic Protein 4, May Lead to a Chondrocyte Phenotype and May Contribute to Bony Hypertrophy"],"prefix":"10.1002","volume":"66","author":[{"given":"AnneMarie C.","family":"Brescia","sequence":"first","affiliation":[{"name":"Thomas Jefferson University, Philadelphia, Pennsylvania, and Nemours\/A.
