Galanin regulates prolactin release and lactotroph proliferation.
The neuropeptide galanin is predominantly expressed by the lactotrophs (the prolactin secreting cell type) in the rodent anterior pituitary and in the median eminence and paraventricular nucleus of the hypothalamus. Prolactin and galanin colocalize in the same secretory granule, the expression of both proteins is extremely sensitive to the estrogen status of the animal. The administration of es...
متن کاملInvestigation of Leptin, Leukemia Inhibitory Factor (LIF), and IL-6 Serum Levels in Myeloid Leukemia
Background: Leptin has been implicated in the differentiation and proliferation of hematopoietic cells. Leukemia inhibitory factor (LIF) may play an important role, along with Interleukin-6 (IL-6) and granulocyte colony stimulating factor (G- CSF), in the regulation of early hematopoietic stem cells. The aim of the study was to evaluate serum level of leptin, LIF, and IL-6 in myeloid leukemia p...
متن کاملMale gonadal function, prolactin secretion and lactotroph population in an experimental model of cirrhosis.
Liver cirrhosis, a highly prevalent chronic disease, is frequently associated with endocrine dysfunctions, notably in the gonadal axis. We evaluated lactotroph population by immunohistochemistry, gonadotropins and prolactin by immunoradiometric assay and testosterone and estradiol by radioimmunoassay in adult male Wistar rats with cirrhosis induced by carbon tetrachloride. No significant differ...
متن کاملPhotoperiodic regulation of prolactin secretion: changes in intra-pituitary signalling and lactotroph heterogeneity.
Many mammalian species utilise day-length (photoperiod) to adapt their physiology to seasonal changes in environmental conditions, via secretion of pineal melatonin. Photoperiodic regulation of prolactin secretion is believed to occur via melatonin-mediated changes in the secretion of a putative prolactin secretagogue, tuberalin, from the pituitary pars tuberalis. Despite the in vivo and in vit...
متن کاملThe effect of clozapine on prolactin secretion at the level of the lactotroph.
Clozapine is an antipsychotic drug which is unusual in that it has no dopamine receptor-blocking activity. Previous studies gave conflicting results whether administration of clozapine induces hyperprolactinemia. In the present study it was shown that a wide concentration range of clozapine does not interfere with dopamine-mediated inhibition of prolactin (PRL) secretion by normal cultured rat ...
