TGF-β1, which has a stimulatory effect on dermal wound healing, has been implicated as the primary causative agent of fibrosis. Glucocorticoids such as dexamethasone normally inhibit wound healing and are capable of antagonizing the fibrotic effect of TGF-β1. Our data indicate the presence of a putative regulatory element responsive to glucocorticoids. Computer sequence analysis of the promoter region of the human TGF-β1 gene (Genbank Accession # J04431) revealed a consensus glucocorticoid response element, GRE (5′-AGAACA) located from (−1081) to (−1086) base pairs from the transcription start site. An oligonucleotide containing this site was obtained and labeled for use in gel mobility shift assays. The labeled oligonucleotide was found to bind both fetal rat skin nuclear extracts and purified recombinant glucocorticoid receptor. Unlabeled oligonucleotides containing a GRE from the rat procollagen type 1 promoter or a commercially supplied GRE competed effectively with the32P-labeled GRE from the TGF-β1 promoter for binding to nuclear extracts. Addition of anti-glucocorticoid receptor revealed a supershifting of the labeled oligonucleotide-nuclear protein complex. These results indicate the presence of a putative GRE in the promoter region of the human TGF-β1 gene.
