Open Access Abstract Genome-wide gene expression was comparatively investigated in early-passage rheumatoid arthritis RA and osteoarthritis OA synovial fibroblasts SFBs n 6 each using oligonucleotide microarrays mRNA protein data were validated by quantitative PCR qPCR and western blotting and immunohistochemistry respectively. Gene set enrichment analysis GSEA of the microarray data suggested constitutive upregulation of components of the transforming growth factor TGF -p pathway in RA SFBs with 2 hits in the top 30 regulated pathways. The growth factor TGF-p1 its receptor TGFBR1 the TGF-p binding proteins LTBP1 2 the TGF-p-releasing .
