Mobility Shift

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 chloramphenicol acetyltransferase (CAT) gene and (2) by co-transfection of promoter constructs with double-stranded oligonucleotides. DNA-mobility-shift assays with radiolabelled alpha 1-TAE demonstrated increased nuclear binding activity after TGF-beta stimulation. Oligonucleotides encoding the alpha 1-TAE, additional upstream regions within the alpha 1(I) promoter, as well as consensus nuclear-factor-1 (NF-1) sequences, competed with the alpha 1-TAE sequence. The two collagen type I genes are stimulated by TGF-beta through different regions of their promoters.
