Negative regulation of gene expression by TGF-beta.


Stromelysin gene expression is transcriptionally activated by a number of growth factors (e.g., EGF and PDGF), tumor promoters (e.g., TPA), and oncogenes (e.g., ras, src) through an AP-1-dependent mechanism. TGF-beta repression of stromelysin induction is mediated at the level of transcription by an element located at position -709 in the rat stromelysin… (More)
