Thyrotropin-releasing hormone (TRH; pyroGlu-His-Pro-NH 2 ), the first hypotha-lamic hypophysiotropic neuropeptide hormone structurally elucidated, stimulates the secretion of TSH and prolactin in vivo and in vitro (1,2). Under certain conditions, TRH has also been suggested to modulate GH ...
hormone (TRH) is a tripeptide hormone secreted by the hypothalamus that stimulates the release of thyrotropin. This tripeptide is involved in the regulation of the hypothalamic pituitary-thyroid axis; it stimulates the synthesis and release from the anterior pituitary of thyrotropin (TSH) and ...
The discovery of TRH led quickly to the discovery of other small peptides that regulate the secretion by the anterior pituitary of its tropic hormones. Such regulation is usually accomplished by increasing or decreasing stimulation. However, growth hormone appears mainly to be regulated by increasing ...
A test of pituitary response to injection of thyrotropin-releasing hormone, which normally stimulates pituitary secretion of thyroid-stimulating hormone (TSH, thyrotropin); used primarily to distinguish pituitary from hypothalamic causes of thyroid disorders; TSH does not rise in cases of pituitary dysfunc...

TRH stimulates the transcription of TSH and α-glycoprotein subunit genes or prolactin genes via the PKC and MEK/ERK signaling pathways, respectively [145], [146]. A recent study showed that TRH regulates the transcription of several hundred genes, with the majority of genes being downregulated ...
Thyrotropin-releasing hormone (TRH) is a hormone produced in the hypothalamus. It stimulates the release of TSH, which then increases thyroid hormones. Thus, TRH controls [1]:energy balance (homeostasis) eating patterns thermogenesis (heat production) autonomic regulation (the unconscious control of ...
TRH (Thyrotropin Releasing Hormone) was isolated as the first hypothalamic hypophysiotropic hormone and identified as the tripeptideamide pyroGlu-His-ProNH 2 . As a neuropeptide hormone TRH not only stimulates the secretion of thyrotropin, but also the secretion of prolactin. In brain, TRH content...

In addition, the pyloric region of the stomach secretes gastrin, a hormone that increases the secretion of hydroc...
