The 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...
متن کاملThe sodium iodide symporter: its emerging relevance to clinical thyroidology.
The sodium iodide symporter (NIS), an integral basolateral cell membrane protein of thyroid follicular cells, is responsible for active accumulation of iodide within the thyroid gland, a critical step in the biosynthesis of thyroid hormones. After cloning of rat NIS cDNA and of its human counterpart (hNIS), molecular characterization of the human NIS gene has revealed that the hNIS coding regio...

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 کاملA perspective view of sodium iodide symporter research and its clinical implications.
The sodium iodide symporter (NIS) is an intrinsic plasma membrane protein that mediates active iodide transport into the thyroid gland and into several extrathyroidal tissues, in particular the lactating mammary gland. Cloning and molecular characterization of the NIS have allowed the investigation of its key role in thyroid physiology as well as its potential pathophysiological and therapeutic...
متن کاملCONTINUING EDUCATION Sodium Iodide Symporter: Its Role in Nuclear Medicine*
Thyroid iodide uptake is basic to the clinical applications of radioiodine. Iodide uptake occurs across the membrane of the thyroid follicular cells through an active transporter process mediated by the sodium iodide symporter (NIS). The recent cloning of the NIS gene enabled the better characterization of the molecular mechanisms underlying iodide transport, thus opening the way to the clarifi...
