Tyrosine hydroxylase (TH) is expressed specifically in catecholaminergic cells. We have identified a novel regulatory sequence in the upstream region of the bovine TH gene promoter formed by a dyad symmetry element (DSE1;-352/-307 bp). DSE1 supports TH promoter activity in TH-expressing bovine adrenal medulla chromaffin (BAMC) cells and inhibits promoter(More)
The cis elements mediating activation of the tyrosine hydroxylase gene by angiotensin II were examined by transfecting tyrosine hydroxylase promoter-luciferase constructs into cultured bone adrenal medullary cells. Angiotensin II-responsive elements are located within -54/+25-bp and -269/-55-bp promoter regions and were identified, respectively, as cyclic(More)
