Transforming-growth-factor-β activation elements in the distal promoter regions of the rat α1 type I collagen gene
15 Nov 1991
Abstract excerpt
We have located a cis-acting element (alpha 1-TAE) within the promoter sequences of the rat collagen alpha 1(I) gene (COL1A1) 1600 bases upstream of the transcription start site which mediates transcriptional activation by transforming growth factor beta (TGF-beta). The functional significance of this region was established by (1) deletion analysis of the alpha 1(I) promoter cloned upstream of the bacterial...
