Abstract/OtherAbstract:
Matrix metalloproteinases are secreted enzymes important in inflammation and tumor invasion. Earlier, we demonstrated that in normal human FS-4 fibroblasts, collagenase and stromelysin mRNA levels are increased not only after treatment with known matrix metalloproteinase inducers such as tumor necrosis factor (TNF), interleukin-1, and 12-O-tetradecanoylphorbol-13-acetate, but also with interferon-beta (IFN-beta). In this study, we compared the regulation of these matrix metalloproteinase genes by TNF and IFN-beta. We show that both TNF and IFN-beta increase steady-state levels of collagenase and stromelysin mRNAs with similar slow kinetics. The glucocorticoid dexamethasone blocked matrix metalloproteinase induction by both cytokines. The protein synthesis inhibitor cycloheximide inhibited collagenase mRNA induction by TNF or IFN-beta, suggesting that induction by both agents is indirect. Consistent with these observations, both TNF and IFN-beta increased c-fos and c-jun mRNA levels. Furthermore, treatment with TNF or IFN-beta increased the transcriptional activity of activator protein-1-responsive chloramphenicol acetyltransferase reporter gene constructs, including a native collagenase promoter-driven chloramphenicol acetyltransferase construct. These findings show that regulation of matrix metalloproteinase gene expression by both TNF and IFN-beta involves the transcription factor activator protein-1 and demonstrate a novel indirect mechanism of type I IFN-induced gene expression.
