Thyrotropin
Based on 1 publication(s) in Google Scholar
Thyrotropin (TSH, Pretiron) is a thyroid-stimulating hormone produced by thyrotrope cells in the anterior pituitary gland. Thyrotropin regulates the endocrine function of the thyroid. Thyrotropin induces transcriptional regulation of TH-gatekeeper genes in tanycytes through the Tshr/Gαq/PKC pathway. Thyrotropin prevents Apoptosis. Thyrotropin has an association of low levels with increased bone remodeling, reduced bone mass and a high fracture risk in mice. Thyrotropin is promising for research of skeletal remodeling, hyperthyroidism.

Activité biologique
Thyrotropin (rhTSH, 0.1-10 nM, 2-3 weeks) enhances human T-cell development[8].
Thyrotropin (bovine thyrotropin, 100 milliunits per mL, the first 24 to 48 h after trypsinization) develops follicle-like structures in dog, human, and bovine thyroid cells[10].
Thyrotropin (1 nM) promotes proliferation of FRTL-5 cells[11].
Thyrotropin regulates thyroid cell proliferation and differentiation[12].
Thyrotropin (10 mU/mL, up to 72 h) prevents apoptosis by promoting cell adhesion and cell cycle progression in FRTL-5 cells[13].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:FRTL-5
-
Concentration:10 mU/mL
-
Incubation Time:up to 72 h
-
Result:Maintained the viability of FRTL-5 cells during the first 48 h.
Showed apparent increase in cell viability at 72 h.
Thyrotropin (i.p.) stimulates thyroid hormone into the circulation in wild-type and heterozygous mice[6].
Thyrotropin (rhTSH, 0.1 μg/g, i.p.) more readily replaces endogenous TSH in mice than in rat thyroid TSH receptors[7].
Thyrotropin (0.05 USP unit twice daily, i.p., 6 days) causes an increase in the weight of the thyroid but no increase in body weight in hereditary dwarf mice[9].
