1 Estrogens have been implicated in the regulation of prolactin gene expression in man, although previous studies have not defined the molecular mechanism whereby estradiol activates the human prolactin gene promoter (hPrl). Estradiol prolactin Homo sapiens
2 We found that estradiol induced a reproducible 1.8-fold activation of the hPrl gene promoter, using pituitary GH3 cells stably transfected with a 5000-bp hPrl promoter fragment linked to luciferase reporter gene. Estradiol prolactin Homo sapiens
3 We found that estradiol induced a reproducible 1.8-fold activation of the hPrl gene promoter, using pituitary GH3 cells stably transfected with a 5000-bp hPrl promoter fragment linked to luciferase reporter gene. Estradiol prolactin Homo sapiens
4 When cells were treated with both estradiol and TNFalpha, we observed synergistic activation of the hPrl promoter, which was mediated by the -1189-bp ERE. Estradiol prolactin Homo sapiens
