Thyroid hormone-responsive elements of the prolactin gene: evidence for both positive and negative regulation.


To analyze the regulation of PRL gene expression by thyroid hormone (T3), fusion gene constructs containing various lengths of the rat PRL gene 5'-flanking sequence linked to the bacterial chloramphenicol acetyltransferase (CAT) gene were transfected into the GH3 cell line. Thyroid hormone had no effect on basal or cAMP-stimulated CAT expression in… (More)
