Induction of mitogen-inducible nuclear orphan receptor by interleukin 1 in human synovial and gingival fibroblasts.
High levels of interleukin 1 (IL-1) found in inflammatory diseases such as rheumatoid arthritis and periodontitis act on the local fibroblasts, resulting in an altered phenotype characterized by hyperplasia and the production of inflammatory mediators and destructive enzymes. The goal of this study was to identify genes induced as an early response to IL-1 in synovial and gingival fibroblasts which might play a regulatory role in the cascade of events leading to their activation. Using the technique of mRNA differential display, we have identified the mitogen-inducible nuclear orphan receptor (MINOR) as a gene up-regulated by IL-1 in human synovial and gingival fibroblasts. The rapid induction of both mRNA and DNA binding activity suggests that MINOR may play an important early role in regulating the response of fibroblasts to inflammation.
