General description

Research area: Cell Signaling

Thyrotropic hormone or thyroid stimulating hormone (TSH) belongs to the glycoprotein hormone family.[1] Thyrotroph cells of the anterior pituitary gland produces TSH and is stored in the secretory granules. It comprises a heterodimer of two noncovalently linked subunits, α and β.[2]

Application

Thyrotropic hormone from human pituitary has been used as a supplement in the fetal thyroid organoid culture medium for stimulating maturation.[3] It has also been used as a medium supplement for primary cell culture, and is used further to study the molecular mechanisms of estrogen-mediated growth stimulation of human thyroid tumor cells.[4]

Biochem/physiol Actions

In children, thyroid hormones are very much essential for the normal cognition and neurodevelopment.[5] Thyroid-stimulating hormone (TSH) test is mainly used to diagnose thyroid function.[6]
The product can enhance vascular endothelial growth factor (VEGF) secretion and angiogenesis in thyroid cancer celllines.[7]TSHR activated by TSH activates both the adenosine 3′,5′-cyclic monophosphate (cAMP) pathway (via Gsa) and the phosphoinositol/calcium (IP/Ca2+; via Gq) second messenger signaling pathway by interacting with Gs and Gq G-proteins.[8] In mature adipocytes, TSH aids in lipid metabolism by inhibiting fatty acid synthase (FASN) expression via, activating protein kinase A (PKA)-dependent phosphorylation of extracellular signal-regulated kinases/p42/p44 (ERK1/2), and c-Jun N-terminal kinase (JNK).[9]
Two-chain glycoprotein hormone. The α-chain is not active, biological specificity attributed rather to the β-chain. Activates adenylate cyclase in the thyroid gland, stimulating iodine uptake, thyroxine synthesis and release. Goitrogenic.
