Prostaglandin E2 (PGE2) inhibits fibroblast proliferation and collagen synthesis. In this study, we compared lung fibroblasts isolated from patients with idiopathic pulmonary fibrosis (F-IPF) and from patients undergoing resectional surgery for lung cancer (F-nl) with respect to their capacity for PGE2 synthesis and their expression and regulation of(More)
The selective induction of PGE(2) synthesis in inflammation suggests that a PGE synthase may be linked to an inducible pathway for PG synthesis. We examined the expression of the recently cloned inducible microsomal PGE synthase (mPGES) in synoviocytes from patients with rheumatoid arthritis, its modulation by cytokines and dexamethasone, and its linkage to(More)
The activity of the [-831; +103] promoter of the human cyclooxygenase-2 gene in cultured rabbit chondrocytes is stimulated 2.9 +/- 0.3-fold by interleukin-1beta and this stimulation depends on [-132; -124] C/EBP binding-and [-223; -214] NF-kappaB binding-sites. The C/EBPbeta and C/EBPdelta factors bind to the [-132; -124] sequence. The [-61; -53] sequence(More)
