Analysis of human sodium iodide symporter immunoreactivity in human exocrine glands.
The human sodium iodide symporter (hNIS) is an intrinsic transmembrane protein that mediates the active transport of iodide across the basolateral membrane of thyroid follicular cells. In addition to normally functioning thyroid tissue, various extrathyroidal tissues, including salivary gland, lacrimal gland, gastric mucosa, choroid plexus, and lactating mammary gland, have been demonstrated to...
متن کاملExpression of sodium iodide symporter in human breast tissues.
PURPOSE Sodium iodide symporter (NIS) expression in breast cancer (BC) tissues suggests the possibility of using radioiodine for diagnostic and therapeutic purposes. This study evaluated NIS protein expression in primary BC samples and its association with BC prognostic markers and thyroid functional parameters. METHODS Fifty-six breast tissue samples from 52 operated women (41 BC, 11 benign ...
متن کاملSodium iodide symporter in health and disease.
Radioiodine-concentrating activity in thyroid tissues has allowed the use of radioiodine as a diagnostic and therapeutic agent for patients with thyroid disorders such as well-differentiated thyroid cancer. However, some extrathyroidal tissues also take up radioiodine, contributing to unwanted side effects of radioiodine therapy. Now that the molecule that mediates radioiodine uptake, the sodiu...

idase (TPO) and incorporation into tyrosyl residues along the thyroglobulin (Tg) backbone. The thyroid hormones T3 and T4 are synthesized by coupling of two iodotyrosine residues and stored in the colloid. All of these steps are stimulated by pituitary-derived thyroid stimulating hormone (TSH), which interacts with the TSH receptor at the basolateral membrane of thyroidal cells, through the cAM...
متن کاملThe sodium iodide symporter and thyroid disease.
The movement of a variety of species from the iodine-rich environment of the sea to the relatively iodine-deficient land has necessitated the development of mechanisms which will trap more efficiently inorganic iodide (I – ) necessary for the formation of thyroid hormones (Venturi et al. , 2000). In man as in other mammals iodide uptake by the thyroid is mediated via a TSHdependent transmembran...
