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.

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.

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.

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

Thyrotropin-releasing hormone receptors in GtoPdb v.2023.1
Thyrotropin-releasing hormone (TRH) receptors (provisional nomenclature as recommended by NC-IUPHAR [14]) are activated by the endogenous tripeptide TRH (pGlu-His-ProNH2). TRH and TRH analogues fail to distinguish TRH1 and TRH2 receptors [29]. [3H]TRH (human, mouse, rat) is able to label both TRH1 and TRH2 receptors with Kd values of 13 and 9 nM ...

Whether leptin acts in the paraventricular nucleus (PVN) to increase sympathetic nerve activity (SNA) is unclear, since PVN leptin receptors (LepR) are sparse.

Intrauterine Zn deficiency favors thyrotropin-releasing hormone-increasing effects on thyrotropin serum levels and induces subclinical hypothyroidism in weaned rats [PDF]
Individuals who consume a diet deficient in zinc (Zn-deficient) develop alterations in hypothalamic-pituitary-thyroid axis function, i.e., a low metabolic rate and cold insensitivity.

Glycosylation in the thyroid gland : vital aspects of glycoprotein function in thyrocyte physiology and thyroid disorders [PDF]
The key proteins responsible for hormone synthesis in the thyroid are glycosylated. Oligosaccharides strongly affect the function of glycosylated proteins.

Large-Scale Combinatorial Deorphanization of Platynereis Neuropeptide GPCRs
Neuropeptides, representing the largest class of neuromodulators, commonly signal by G-protein-coupled receptors (GPCRs). While the neuropeptide repertoire of several metazoans has been characterized, many GPCRs are orphans.
