Nuclear receptors inhibit synthesis of collagenase-1 (matrix metalloproeinase-1; MMP-1), an enzyme that degrades interstitial collagens and contributes to joint pathology in rheumatoid arthritis. SMRT (Silencing Mediator for Retinoid and Thyroid hormone receptors) mediates the repressive effect of nuclear receptors at hormone responsive elements (HREs), prompting us to investigate whether this co-repressor could also regulate transcription of MMP-1, which lacks any known HREs. We find that primary synovial fibroblasts express SMRT. When over-expressed by transient transfection, SMRT inhibits MMP-1 promoter activity induced by interleukin-1 (IL-1), phorbol phorbol myristate acetate (PMA) or v-Src. SMRT apparently inhibits MMP-1 gene expression by interfering with one or more transcriptional elements clustered in a region between −321 and +63. We conclude that SMRT negatively regulates MMP-1 synthesis through a novel, HRE-independent mechanism that involves proximal regions of the MMP-1 promoter.
