Thyrotropin-releasing hormone receptors -- similarities and differences [PDF]
Thyrotropin-releasing hormone (TRH) initiates its effects by interacting with cell-surface membrane receptors. Two G protein-coupled receptors for TRH, TRH receptor type 1 (TRH-R1) and TRH receptor type 2 (TRH-R2), have been cloned from mammals. In this review, we compare TRH-R1 and TRH-R2 with regard to their tIssue distribution, binding affinities ...

Distinct and histone-specific modifications mediate positive versus negative transcriptional regulation of TSHalpha promoter. [PDF]
Hormonally-regulated histone modifications that govern positive versus negative transcription of target genes are poorly characterized despite their importance for normal and pathological endocrine function.

Dysregulation of the preovulatory surge (PS) leads to lowered egg production. The hypothalamo–pituitary–thyroid (HPT) axis has been shown to influence plasma progesterone levels and follicle ovulation.

Cloning and Characterization of the Chicken Thyrotropin-Releasing Hormone Receptor* [PDF]
We report on the cloning of the full-length complementary DNA for the chicken TRH receptor. Although the TRH receptor has been cloned from several mammalian species, this is the first report from another vertebrate class. The ligand binding pocket, which is situated in the transmembrane helices of the mouse and rat TRH receptors, is completely ...

Impact of One-Week Administration of Dihydrotestosterone in Rat Anterior Pituitary Gland
Hyperandrogenism causes dysfunction of the hypothalamic–pituitary–gonadal (HPG) axis in reproductive women. In this study, we examined the effects of dihydrotestosterone (DHT) on characteristic changes in rat anterior pituitary gland samples.

Taltirelin is a superagonist at the human thyrotropin-releasing hormone receptor [PDF]
Taltirelin (TAL) is a thyrotropin-releasing hormone (TRH) analog that is approved for use in humans in Japan. In this study, we characterized TAL binding to and signaling by the human TRH receptor (TRH-R) in a model cell system. We found that TAL exhibited lower binding affinities than TRH and lower signaling potency via the inositol-1,4,5 ...

Liver X receptor regulation of thyrotropin-releasing hormone transcription in mouse hypothalamus is dependent on thyroid status. [PDF]
Reversing the escalating rate of obesity requires increased knowledge of the molecular mechanisms controlling energy balance. Liver X receptors (LXRs) and thyroid hormone receptors (TRs) are key physiological regulators of energetic metabolism. Analysing

Dimerization of the thyrotropin-releasing hormone receptor potentiates hormone-dependent receptor phosphorylation [PDF]
The G protein-coupled thyrotropin (TSH)-releasing hormone (TRH) receptor forms homodimers. Regulated receptor dimerization increases TRH-induced receptor endocytosis. These studies test whether dimerization increases receptor phosphorylation, which could potentiate internalization.
