WebPit-1 is a transcription factor that binds to several sites in the promoter of the PRL gene to allow for synthesis of PRL in the anterior pituitary. Most extrapituitary production of PRL is controlled by a superdistal promoter [3]. Neurosecretory dopamine neurons inhibit PRL secretion via D2 receptors. WebThe pituitary intermediate lobe normally contains only Tpit-expressing melanotrophs. Inactivation of the Tpit gene results in almost complete loss of POMC-expressing cells in this tissue, which now has a large number of gonadotrophs and a few clusters of Pit-1-independent thyrotrophs. The role of Tpit as a negative regulator of gonadotroph ...
