Prolactin induction of nuclear pSTAT5 in neuroendocrine dopaminergic neurons of the arcuate nucleus. Representative images of vehicle (A), 10 ng (B,B′), 500 ng (C), and 5 μg icv prolactin dose-treated brains (D,D′), showing the distribution of nuclear pSTAT5 (blue/black) and cytoplasmic tyrosine hydroxylase (brown) staining in arcuate nucleus sections. The percentage of TH-positive neurons displaying nuclear pSTAT5 in response to 10 ng (n = 7), 500 ng (n = 7), or 5 μg (n = 6) prolactin icv, or vehicle (n = 6) in the dorsomedial and ventrolateral divisions of the arcuate nucleus is summarized in E,F, respectively. Bars with different letters are significantly different compared with vehicle (P < 0.05). Scale bars = 100 μm in A–D; 25 μm in B′,D′.
