Thyrotropin-releasing hormone (TRH) causes a variety of thyroidal and non-thyroidal effects, the best known being the feedback regulation of thyroid hormone levels. This was employed in the TRH stimulation test, which is currently little used. The role of TRH as a cancer biomarker is minor, but exaggerated responses to TSH and prolactin levels in breast cancer led to the hypothesis of a potential role for TRH in the pathogenesis of this disease. TRH is a rapidly degraded peptide with multiple targets, limiting its suitability as a biomarker and drug candidate. Although some studies reported efficacy in neural diseases (depression, spinal cord injury, amyotrophic lateral sclerosis, etc.), therapeutic use of TRH is presently restricted to spinocerebellar degenerative disease. Regulation of TRH production in the hypothalamus, patterns of expression of TRH and its receptor in the body, its role in energy metabolism and in prolactin secretion are addressed in this review.

Fluoxetine (FLX), a typical selective serotonin reuptake inhibitors, has been frequently detected in aquatic environment and wild fish. However, little is known about its effect on thyroid endocrine system. In the present study, zebrafish (Danio rerio) embryos were exposed to 1, 3, 10, and 30 μg/L of FLX for 6 days.

Hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI) is a novel class of orally administered medications for renal anemia in patients with end-stage renal disease (ESRD). Roxadustat, a HIF-PHI, has a structure similar to that of triiodothyronine and may work as an agonist for thyroid hormone receptor-beta in the pituitary gland and/or hypothalamus. Therefore, roxadustat may cause central hypothyroidism due to suppressing thyroid-stimulating hormone (TSH) release in the pituitary gland and/or thyrotropin-releasing hormone release in the hypothalamus.

Graves' disease is caused by overactivation of the thyroid-stimulating hormone receptor (TSHR). One approach for its treatment may be the use of negative allosteric modulators (NAM) of TSHR, which normalize TSHR activity and do not cause thyroid hormone (TH) deficiency. The aim of the work was to study the effect of a new compound 5-amino-4-(4-bromophenyl)-2-(methylthio)thieno[2,3-d]pyrimidine-6-carboxylic acid N-tert-butylamide (TPY4) on the basal and TSH-stimulated TH production in cultured FRTL-5 thyrocytes and on basal and thyrotropin-releasing hormone (TRH)-stimulated TH levels in the blood of rats.

Feeding behavior is regulated by a complex network of endogenous neuropeptides. In chordates, this role is suggested to be under the control of diverse factors including thyrotropin-releasing hormone (TRH). However, whether this regulatory activity of TRH is functionally conserved in non-chordate metazoans, and to what extent this process is underpinned by interactions of TRH with other neuropeptides such as cholecystokinin (CCK, known as a satiety signal), remain unclear.
