Immunoanalysis indicates that the sodium iodide symporter is not overexpressed in intracellular compartments in thyroid and breast cancers.
OBJECTIVE The active transport of iodide into thyroid cells is mediated by the Na(+)/I(-) symporter (NIS) located in the basolateral membrane. Strong intracellular staining with anti-NIS antibodies has been reported in thyroid and breast cancers. Our initial objective was to screen tumour samples for intracellular NIS staining and then to study the mechanisms underlying the altered subcellular ...
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...

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 کاملMinireview: The sodium-iodide symporter NIS and pendrin in iodide homeostasis of the thyroid.
Thyroid hormones are essential for normal development and metabolism. Thyroid hormone biosynthesis requires iodide uptake into the thyrocytes and efflux into the follicular lumen, where it is organified on selected tyrosyls of thyroglobulin. Uptake of iodide into the thyrocytes is mediated by an intrinsic membrane glycoprotein, the sodium-iodide symporter (NIS), which actively cotransports two ...
متن کاملRadioiodide uptake and sodium iodide symporter expression in breast carcinoma.
Breast cancer is a common malignancy in women all over the world and novel therapeutic approaches are required for the treatment of patients who become refractory to conventional therapies. Thyroid cancer is being treated successfully with radioiodine since many years. The iodide is transported inside the thyroid epithelial cell via sodium iodide symporter (NIS) which is a trans-membrane protei...
