Sex steroids are major regulators of PRL receptor expression in rat liver. Using a probe encoding the rat PRL receptor we have studied receptor mRNA levels in female rat liver during ontogeny and in response to estrogen treatment. Steady state mRNA levels were determined by Northern blot and densitometric analysis. Messenger RNA levels have been compared to the number of binding sites, which was assessed by Scatchard analysis of [125I]ovine PRL binding in membrane preparations. Our results show that steady state mRNA and binding levels of PRL receptors are both regulated by development and estrogens, but that binding does not exactly parallel mRNA levels. From the developmental stages of prepuberty to adult, receptor numbers increase 8-fold, whereas mRNA levels increase 3-fold. Estrogen treatment stimulates receptor levels 6-fold, but mRNA levels are only increased 3-fold. These results suggest that PRL receptor gene expression in rat liver is regulated at the transcriptional or posttranscriptional level as well as at the translational level.
