In a previous report (Marigo, V., Volpin, D., and Bressan, G. M. (1993) Biochim. Biophys. Acta 1172, 31-36) it was shown that the elastin promoter contains a region mediating transcriptional activation by TGF-beta in aorta cells, but not in tendon fibroblasts from chick embryos. In this paper we have identified the sequence responsible for this effect by a combination of CAT assays with mutant constructs, DNase I footprinting and electrophoretic mobility shift assays. This TGF-beta responsive element binds different nuclear proteins in chick embryo aorta and tendon cells. Whereas association of the aorta protein(s) to the element is necessary for TGF-beta activation, binding of the tendon protein(s) has apparently no effect on promoter stimulation by the cytokine.
