Sodium-iodide symporter mediates iodide secretion in rat gastric mucosa in vitro

In vivo studies on rats have demonstrated that considerable amounts of iodide are transported from the bloodstream into the gastric lumen. The mechanisms for and functional significance of this transport are poorly understood. Active (driven by Na+/K+-ATPase) iodide transport into thyroid follicular cells is mediated by the sodium-iodide symporter (NIS), which is also abundantly expressed in gastric mucosa. We aimed to further investigate the iodide transport in gastric mucosa and the possible role of NIS in this transport process. Iodide transport in rat gastric mucosa was studied in vitro in an Ussing chamber system using I-125 as a marker. The system allows measurements in both directions over a mucosal specimen. A considerable transport of iodide (from the serosal to the mucosal side) was established across the gastric mucosa, whereas in the opposite direction (mucosa to serosa), iodide transport was negligible. Sodium perchlorate (NaClO4), a competitive inhibitor of NIS, and ouabain, an inhibitor of the Na+/K+-ATPase, both attenuated gastric iodide transport from the serosal to the mucosal side. To investigate a possible neuroendocrine regulation of the iodide transport identified to occur from the serosal to the mucosal side of the stomach, thyroid-stimulating hormone (TSH), thyrotropin-releasing hormone (TRH), vasoactive intestinal peptide (VIP), histamine, or nitric oxide donor S-nitroso-N-acetyl-D,L-penicillamine (SNAP) was added. None of these substances influenced the iodide transport. We conclude that iodide is actively transported into the gastric lumen and that this transport is at least partly mediated by NIS. Additional investigations are needed to understand the regulation and significance of this transport.

SEQUENTIAL FLOW-INJECTION POTENTIOMETRIC DETERMINATION OF IODIDE AND IODINE IN POVIDONE-IODINE PHARMACEUTICALS

A potentiometric sensor-based flow-injection system for determining iodide is described. The system utilizes a flow-through sandwich cell and incorporates iron (II)-tris bathophenanthroline iodide ion pair complex as an exchange site in a PVC matrix membrane. The sensor displays a fast response for 10(-1) to 10(-6) M iodide ion with an anionic slope of 59.1 +/- 0.3 mV/concentration decade over the pH range 1 to 11. The experimental setup offers a precise, sensitive, selective and high sample throughput technique for determining iodide and iodine over a wide range of concentration. The limit of detection is 0.5 ppm iodide in a 20 muL sample. The average recovery is 99.8%, and the mean standard deviation is 0.5%. Sequential flow-injection determination of iodide and iodine in some pharmaceutical preparations containing povidone iodine is performed by sample injection in a sodium sulfate-ascorbic acid stream and monitoring of the total iodide equivalent to I- and I2. This is followed by injection of a second sample in an alkaline resorcinol stream and measuring of the iodide equivalent to I- and 1/2 I2. Iodine and iodide concentrations are calculated from the consecutive signals. The method gives results in good agreement with those obtained by the United States Pharmacopeia.

Minireview: 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 sodium cations per each iodide anion. NIS-mediated transport of iodide is driven by the electrochemical sodium gradient generated by the Na+/K+-ATPase. NIS is expressed in the thyroid, the salivary glands, gastric mucosa, and the lactating mammary gland. TSH and iodide regulate iodide accumulation by modulating NIS activity via transcriptional and posttranscriptional mechanisms. Biallelic mutations in the NIS gene lead to a congenital iodide transport defect, an autosomal recessive condition characterized by hypothyroidism, goiter, low thyroid iodide uptake, and a low saliva/plasma iodide ratio. Pendrin is an anion transporter that is predominantly expressed in the inner ear, the thyroid, and the kidney. Biallelic mutations in the SLC26A4 gene lead to Pendred syndrome, an autosomal recessive disorder characterized by sensorineural deafness, goiter, and impaired iodide organification. In thyroid follicular cells, pendrin is expressed at the apical membrane. Functional in vitro data and the impaired iodide organification observed in patients with Pendred syndrome support a role of pendrin as an apical iodide transporter.

Iodide handling by the thyroid epithelial cell

Iodination of thyroglobulin, the key event in the synthesis of thyroid hormone, is an extracellular process that takes place inside the thyroid follicles at the apical membrane surface that faces the follicular lumen. The supply of iodide involves two steps of TSH-regulated transport, basolateral uptake and apical efflux, that imprint the polarized phenotype of the thyroid cell. Iodide uptake is generated by the sodium/iodide symporter present in the basolateral plasma membrane. A candidate for the apical iodide-permeating mechanism is pendrin, a chloride/iodide transporting protein recently identified in the apical membrane. In physiological conditions, transepithelial iodide transport occurs without intracellular iodination, despite the presence of large amounts of thyroglobulin and thyroperoxidase inside the cells. The reason is that hydrogen peroxide, serving as electron acceptor in iodide-protein binding and normally produced at the apical cell surface, is rapidly degraded by cytosolic glutathione peroxidase once it enters the cells. Iodinated thyroglobulin in the lumen stores not only thyroid hormone but iodine incorporated in iodotyrosine residues as well. After endocytic uptake and degradation of thyroglobulin, intracellular deiodination provides a mechanism for recycling of iodide to participate in the synthesis of new thyroid hormone at the apical cell surface.

Histidine residue at position 226 is critical for iodide uptake activity of human sodium/iodide symporter

The sodium/iodide symporter (SLC5A5; also known as NIS), a transamembrane glycoprotein principally in the thyroid gland, is responsible for the accumulation of iodide necessary for thyroid hormones. Our previous study indicated that a novel exon 6 deletion (residues 233-280) in SLC5A5 loses the iodide uptake activity. Herein we characterized the role of His-226 in iodide transport of SLC5A5. His-226, a highly conserved extracellular residue among SLC5A5 homologs, was replaced with alanine, aspartic acid, glutamic acid, or lysine. All the SLC5A5 mutants were expressed normally in the cells and targeted correctly to the plasma membrane. However, all of the mutants displayed severe defects in iodide uptake, suggesting that His-226 was critical for iodide uptake. Kinetic analysis further showed that mutation at His-226 led to a dramatic decrease in These findings suggested that the decreased levels of iodide uptake activity of SLC5A5 mutants resulted from lower catalytic rates. In Conclusion, our-data first identified the involvement of extracellular charged amino acid residue in the iodide uptake ability of SLC5A5.

Acyl iodides in organic synthesis: IV. Reaction of acetyl iodide with carboxylic acids

In contrast to acyl chlorides, reactions of acetyl iodide with monocarboxylic acids follow the exchange pattern to give the corresponding acyl iodides and acetic acid. The reaction attracts interest from the preparative viewpoint as a simple and convenient route to acyl iodides. Acetyl iodide reacts with phthalic acid, yielding acetic acid and phthalic anhydride, while the reaction of acetyl iodide with oxalic acid leads to formation of acetic acid, carbon(II) oxide, and molecular iodine.

The use of trimethylsilyl iodide as a synthon in coordination chemistry

Trimethylsilyl iodide is shown to be an efficient metathetical reagent for preparing transition-metal iodides from the corresponding chlorides. though often complications can cause problems. These include reduction of the starting metal chloride when its oxidation state is high, due to the reaction of iodide, and even oxidation of low-oxidation-state compounds, presumably by incipient silyl cations. Finally, some very inert chlorides, such as of iridium(III), react too slowly with the iodide under the experimental conditions, and simple reaction with solvent becomes predominant.
