TSH Receptor

Thyrotropin receptor; Thyroid-stimulating hormone Receptor

The TSH receptor (TSHR) is a member of the glycoprotein hormone receptors, a subfamily of family A G protein-coupled receptors. The TSH receptor (TSHR) undergoes complex post –translational modifications including intramolecular cleavage and receptor multimerization. TSHR and its endogenous ligand thyrotropin (TSH) are of essential importance for growth and function of the thyroid gland and proper function of the TSH/TSHR system is pivotal for production and release of thyroid hormones.

The TSHR activates different G-protein subtypes and signaling pathways, whereby Gs- and Gq-induced signaling are probably of highest importance. TSH and its receptor are required for thyroid hormone synthesis and release in the thyroid gland. Dysfunctions of the TSHR are the underlying cause of various gain- or loss-of-function phenotypes associated with thyroid malfunction. It has been suggested that the TSHR is involved in the development and mechanisms of ophthalmopathy. TSHR is also a major autoantigen for autoimmune diseases of the thyroid gland. In addition, TSHR has been proposed to be a potent target against thyroid cancer with several experimental compounds under development.

    Pentacosafluorotridecanoic Acid
    Perfluorotridecanoic acid (PFTrDA) is a perfluoroalkyl substance (PFAS). Embryo larval exposure of PFTrDA induces yolk sac edema and increases mRNA expression of thyroid hormone synthesis genes, including tshβ, in zebrafish when used at concentrations of 0.1 and 0.3 mg/L, respectively. PFTrDA (10 mg/kg) decreases serum testosterone and luteinizing hormone levels, testis palmitic acid, linoleic acid, and oleic acid levels, and the number of Leydig cells in rats in late puberty. Maternal plasma levels of PFTrDA during gestation are positively associated with the development of eczema in female, but not male, infants, and liver levels of PFTrDA are higher in cancerous human livers compared with non-cancerous human livers. It has been found in marine mammals.
