Molecular Biology of Thyrotropin
Endocrine Reviews, 1989Introduction THE pituitary glycoprotein hormone TSH is synthesized and secreted by the thyrotropes in the anterior pituitary. TSH acts on the thyroid gland to increase the production of the thyroid hormones T3 and T4, which then act on organs throughout the body to modulate growth and various metabolic processes.

Hypothalamic Thyrotropin-Releasing Hormone and Thyrotropin Biological Activity
Thyroid, 1998Hypothalamic thyrotropin-releasing hormone (TRH) is the main positive regulator of thyrotropin (TSH) secretion. TRH action and the negative feedback of thyroid hormone are integrated in order to guarantee appropriate thyroid stimulation. TRH action affects various steps of the biosynthetic process within thyrotrophs, with major effects on the ...

Thyrotropin Pituitary Adenomas
World Neurosurgery, 2014irkman et al., by reporting on their experience at National Hospital for Neurology and Neurosurgery of London K with thyrotropin (TSH)-expressing pituitary adenomas, have contributed an important and welcomed addition to the literature about pituitary tumors.

The effect of synthetic thyrotropin releasing hormone (TRH) on serum thyrotropin (hTSH), prolactin (hPRL), chorionic thyrotropin (hCT), and placental lactogen (hPL) was investigated in 13 normal pregnant women who had therapeutic abortions at 8–22 weeks of gestation. Five hundred μg TRH injected iv increased serum hTSH consistently in all subjects. The

The thyrotropin response to thyrotropin-releasing hormone in endogenous depression
Psychoneuroendocrinology, 1981Abstract The maximal response of thyrotropin (TSH) to thyrotropin-releasing hormone (TRH) (Δ max TSH) is reduced in endogenous depression (ED). In the majority of studies Δ max TSH was reduced to the same degree in unipolar and bipolar depression, as well as in manic patients.

Clinical studies of thyrotropin and thyrotropin-releasing-hormone
Pharmacology & Therapeutics. Part C: Clinical Pharmacology and Therapeutics, 1977Summary Most clinical studies with thyrotropin have utilized bovine TSH since human TSH has not been available, but more general use of the latter may be possible in the near future. The use of BTSH has been limited to stimulation testing of thyroid function, and the compound has shown lesser, but occasional, usefulness in the treatment of metastatic

Thyrotropin Response to Thyrotropin Releasing Hormone in Normal Subjects
European Journal of Clinical Investigation, 1974Abstract. 200 (ig of synthetic thyrotropin releasing hormone (TRH) was administered intravenously to six normal men and six normal women on two occasions. A positive correlation between the basal TSH level and maximal serum TSH after TRH was found. The TSH responses in the mid‐follicular and mid‐luteal phase were similar.

Thyrotropin-releasing hormone and thyrotropin secretion.
The Journal of laboratory and clinical medicine, 1987Thyrotropin (TSH) secretion is regulated primarily by thyroid hormones and thyrotropin-releasing hormone (TRH). Normally, TSH secretion is exquisitely sensitive to small increases and decreases in serum thyroid hormone concentrations when they occur as a result of alterations in thyroid secretion.
