6-[124I]Iodo-9-pentylpurine for imaging the activity of the sodium iodide symporter in the brain.

Journal of Medicinal Chemistry, 2020
Iodide homeostasis and thyroid hormone metabolism in the brain are potentially related to changes in activity of the sodium iodide symporter (NIS). No radiotracers are currently available for imaging brain NIS activity.

Implications of the molecular characterization of the sodium-iodide symporter (NIS)

Experimental and Clinical Endocrinology & Diabetes, 2009
The recently cloned sodium-iodide symporter (NIS) represents a key molecule for thyroid function by efficiently accumulating iodide from the circulation into the thyrocyte against an electrochemical gradient. This uptake requires energy, is coupled to the action of Na+/K+-ATPase, and stimulated by TSH, the main hormone regulating thyroid-specific ...

Regulation of the sodium/iodide symporter by retinoids - a review

Experimental and Clinical Endocrinology & Diabetes, 2001
Decrease or loss of iodide uptake, due to impaired expression and/or function of the sodium/iodide-symporter (NIS), is a major obstacle to the treatment of advanced thyroid carcinomas by radioiodide therapy. Several approaches are being evaluated to optimise or restore sufficient iodide transport in those cases, among them retinoid therapy.

Gene therapy with sodium/iodide symporter in hepatocarcinoma

Experimental and Clinical Endocrinology & Diabetes, 2001
The ability of thyroid cells to accumulate iodide is a prerequisite for successful radioiodide therapy of benign thyroid diseases and differentiated thyroid carcinoma. The transport of iodide across the cell membrane is mediated by the sodium iodide symporter (hNIS). Employing a bicistronic retroviral vector for the transfer of the hNIS coding sequence

Small‐Molecule Inhibitors of Sodium Iodide Symporter Function

ChemBioChem, 2008
AbstractThe Na+/I− symporter (NIS) mediates iodide uptake into thyroid follicular cells. Although NIS has been cloned and thoroughly studied at the molecular level, the biochemical processes involved in post‐translational regulation of NIS are still unknown. The purpose of this study was to identify and characterize inhibitors of NIS function.

In vivo imaging and tumor therapy with the sodium iodide symporter

Journal of Cellular Biochemistry, 2003
AbstractThere has been great progress in the design of vectors for cancer gene therapy. However, it has been difficult to translate success in the laboratory into clinical practice. A major hurdle in understanding these failures has been the relative difficulty in monitoring repeatedly and non‐invasively the biodistribution, gene expression and ...

Characterization of the upstream enhancer of the rat sodium/iodide symporter gene

Experimental and Clinical Endocrinology & Diabetes, 2001
We previously demonstrated the presence of an enhancer that is located between nucleotides - 2264 and - 2495 in the 5' flanking region of the rat sodium/iodide symporter (NIS) gene (Ohno et al., 1999). When attached to NIS or heterologous promoters, this 232 bp fragment, which we call NUE, is able to stimulate transcription in a thyroid-specific and ...

A systematic evaluation of sorting motifs in the sodium–iodide symporter (NIS)

Biochemical Journal, 2016
The sodium–iodide symporter (NIS) is an integral membrane protein that plays a crucial role in iodide accumulation, especially in the thyroid. As for many other membrane proteins, its intracellular sorting and distribution have a tremendous effect on its function, and constitute an important aspect of its regulation.

Novel Sodium/Iodide Symporter Compound Heterozygous Pathogenic Variants Causing Dyshormonogenic Congenital Hypothyroidism.

Thyroid, 2019
BACKGROUND Iodide transport defect (ITD) is an autosomal recessive disorder caused by deficient iodide accumulation into the thyroid follicular cell. ITD is an uncommon cause of dyshormonogenetic congenital hypothyroidism that results from inactivating ...
