Prolactin signalling in murine hair growth
Although prolactin has been shown to entrain hair growth cycles in seasonally responsive mammals, no comparable role has been identified in the age-dependent pelage replacement of rodents. Prolactin binds to dimerised membrane-associated prolactin receptors (PRLR) on target organs and initiates …

Neuroanatomical specificity of prolactin-induced hyperphagia and expression of fos-like immunoreactivity following central administration of prolactin
… understanding of the orexigenic properties of prolactin (PRL) in female rats. PRL is known to increase food intake in virgin female rats when injected intracerebroventricularly (icv) but it is not known where in the brain PRL acts to promote feeding behavior. The first series of studies …

The Role of Prolactin in CCL28 Regulation
… whether CCL28 expression is regulated by prolactin signaling.

Transcriptional regulation of the prolactin gene in turkeys
… with the onset of incubation behavior. Prolactin (Prl) is involved in the induction and maintenance of incubation behavior in birds, and understanding the regulatory mechanism(s) of Prl gene expression will provide fundamental information to manipulate Prl production for better …

Central mechanisms of prolactin-releasing peptides orexigenic effect in chickens
Prolactin-releasing peptide (PrRP) is an endogenous hypothalamic neuropeptide that when exogenously injected increases food intake in chickens, but decreases it in rodents and goldfish. We designed three sets of experiments to elucidate the mechanisms of PrRP's orexigenic effect in chicks. In …

Progesterone and Prolactin Profiles of the Female Asian Elephant (Elephas Maximus)
Serum progesterone and prolactin concentrations were determined daily (around estrus), weekly (throughout the estrous cycle), and bimonthly (during gestation) in 8 female Asian elephants. A total of 18 estrous cycles with 4 resulting in conception are described. Early gestational values are shown …

Investigation of prolactin-related vasoinhibin in sera from patients with diabetic retinopathy
… N-terminalen 14,15, 16, 17 und 18 kDa-Fragmente (prolactin-related vasoinhibin, PRL-V) des menschlichen Prolaktins natürliche Inhibitoren der Neovaskularisation in der Retina sind. Diese N-terminalen PRL-Fragmente gehören zur Familie der Vasoinhibine, einer Gruppe von Peptiden, die aufgrund ihrer …

The Role of Prolactin in the Cellular Response to DNA Damaging Agents
High serum levels of the peptide hormone prolactin are associated with increased breast cancer risk and poor prognosis. Prolactin is also involved in breast cancer resistance to different chemotherapeutics. The overall goal of this project is to investigate potential pathways involved in prolactin …

Modulation of humoral immunity in the rat by 17beta-estradiol and prolactin
… than do the males. Many studies have shown that prolactin (PRL) and estradiol (E$\sb2$) augment immunity. Given that E$\sb2$ is a potent physiologic stimulus for the release of PRL from the pituitary, it is plausible that PRL mediates the influence of E$\sb2$ upon the immune system. To test this …

The Mapping of Transcription Factor Binding Sites in the Turkey Prolactin Gene
… labor intensive. The anterior pituitary hormone prolactin (PRL) is involved in the onset of incubation in the turkey hen. Levels of circulating PRL and PRL mRNA are 10X greater in photostimulated hens than in photorefractory hens, 20X greater in laying hens, and 100X greater in incubating hens. …

Delineating the role of prolactin-inducible protein (Pip) in breast cancer lung metastasis
… remains a major challenge for patients. The prolactin-inducible protein (PIP) is a highly breast specific gene product of BC. Because of such relevant attributes, it is considered a valuable BC biomarker frequently used in the clinic to determine the origin of an unknown metastatic carcinoma. …

The effects of incubation manipulation on prolactin secretion in Adélie penguins (Pygoscelis adeliae)

The control of prolactin secretion and the role of gonadotrophin releasing hormone in the production of concordant secretory spikes of luteinizing hormone and prolactin in the luteal phase of the menstrual cycle
The control of prolactin secretion is a complex interaction of peptides and neurotransmitters acting either in an inhibitory or stimulating way to effect final secretion of this hormone from the lactotrope cell in the anterior hypothalamus. These factors may act either directly on the lactotrope …

The use of free tryptophan and prolactin as peripheral indices of brain serotoninergic activity
… namely venous concentrations of f-Trp and prolactin (PRL), under three different experimental conditions. It was hypothesised that the changes in venous concentrations of f-Trp and PRL would exhibit similar patterns. Plasma f-Trp concentration increased by 110% after 2 h of cycling in …

Changes in behaviour and prolactin secretion in bantam hens (gallus domesticus) during extended incubation
