Cell-specific Induction of Distinct Oncogenes of the Jun Family Is Responsible for Differential Regulation of Collagenase Gene Expression by Transforming Growth Factor-β in Fibroblasts and Keratinocytes

Abstract excerpt

Transforming growth factor-beta (TGF-beta) plays a major role in regulating connective tissue deposition by controlling both extracellular matrix production and degradation. In this study, we show that TGF-beta transcriptionally represses both basal and tumor necrosis factor-alpha-induced collagenase (matrix metalloprotease-1) gene expression in dermal fibroblasts in culture, whereas it activates its expression...
