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.

SPONTANEOUS RAMAN-SPECTRA OF THE CYANINE DYE DODCI AND ITS 6 ANALOGS USING TITANIUM-SAPPHIRE LASER EXCITATION

The infrared and spontaneous Raman spectra of the cyanine dye 3,3-diethyloxadicarbocyanine iodide (DODCI) and its six analogues, 3,3′-diethylthiacarbocyanine iodide (DTCI), 3,3′-diethyl-9-methylthiacarbocyanine iodide (MDTCI), 3,3′-diethylthiadicarbocyanine iodide (DTDCI), 3,3′-diethylselenacarbocyanine iodide (DSCI), 3,3′-diethyloxacarbocyanine iodide (DOCI), and 3,3′-diethyloxatricarbocyanine iodide (DOTCI), have been measured.

Dietary flavonoids and iodine metabolism

Flavonoids have inhibiting effects on the proliferation of cancer cells, including thyroidal ones. In the treatment of thyroid cancer the uptake of iodide is essential. Flavonoids are known to interfere with iodide organification ill vitro, and to cause goiter. The influence of flavonoids on iodine metabolism was studied in a human thyroid cancer cell line (FTC-133) transfected with the human sodium/iodide transporter (NIS). All flavonoids inhibited growth, and iodide uptake was decreased in most cells. NIS mRNA expression was affected during the early hours after treatment, indicating that these flavonoids can act on NIS. Pendrin mRNA expression did not change after treatment. Only myricetin increased iodide uptake. Apeginin, luteolin, kaempferol and F21388 increased the efflux of iodide, leading to a decreased retention of iodide. Instead myricetin increased the retention of iodide; this could be of use in the radioiodide treatment of thyroid cancer.

THE INFLUENCE OF LEAD IODIDE AEROSOL DISPERSITY ON ITS ICE-FORMING ACTIVITY

Lead iodide aerosol ice-forming activity obtained by thermocondensation in a cloud chamber has been studied. Lead iodide aerosols have been found to yield a maximum number of 2 x 10(18) kg-1 of ice crystals at 253 K. At 263 K the maximum output amounts to 3 x 10(16) kg-1 and at 268 K lead iodide aerosols are generally inert. Ice-forming characteristics of the lead iodide are inferior to those of silver iodide and copper acetylacetonate, but are better than those of phloroglucinol and copper sulphide. The possibility of producing ice-forming nuclei with 10-fold reduced lead iodide content is considered by coating inert nuclei with small quantities of active substance. The activity of such coated nuclei is estimated.

IODIDE BUFFER SYSTEMS FOR THE CALIBRATION OF IODIDE-SELECTIVE ELECTRODES

A new approach to the creation of anion buffer systems is proposed, which extends the linear range. The new iodide buffer systems, containing (1) HgI2 precipitate, CaEDTA(2-), Ca2+, HgEDTA(2-), and (2) HgI2 precipitate, chloride complexes of Hg2+ and excess of Cl- ions, are proposed for the calibration of iodide-selective electrodes at pI > 5. It is shown with the help of these buffers, that a solid-state Orion 94-53 iodide-selective electrode keeps linear Nemstian response up to pI = 7.5. Iodide buffer systems are used for the estimation of the reliability of literature data on selectivity coefficients of iodide-selective electrodes with respect to Cl- ions.

Efficacy of methyl iodide and synergy with chloropicrin for control of fungi

Efficacy of soil fumigation with methyl bromide and methyl iodide against Botrytis cinerea, Colletotrichum gloeosporioides, Fusarium oxysporum, Gliocladium virens, Phytophthora citricola, Phytophthora citrophthora, Pythium ultimum, Rhizoctonia solani and Verticillium dahliae was determined in laboratory experiments in closed fumigation chambers. Pythium ultimum was the most sensitive fungal species with EC50 values for methyl bromide and methyl iodide of 15.5 and 8.6 mu M, respectively. R solani was the least sensitive with EC50 values of 253.4 and 161.4 mu M for methyl bromide and methyl iodide, respectively. Relative potency ([methyl bromide]/[methyl iodide]) values ranged from 5.2 for P citricola to 1.5 for F oxysporum. Methyl iodide was 2.7 more efficacious than methyl bromide averaged over all fungal species. Methyl bromide/chloropicrin and methyl iodide/chloropicrin applied jointly were 2.2 and 2.8 times more efficacious, respectively, against F oxysporum than when the compounds were applied singly. Combining methyl bromide and methyl iodide with chloropicrin resulted in a significant synergistic increase in activity against F oxysporum. (C) 2000 Society of Chemical Industry.

Differential gene expression analysis of iodide-treated rat thyroid follicular cell line PCCl3

The inhibitory effect of supraphysiological iodide concentrations on thyroid hormone synthesis (Wolff – Chaikoff effect) and on thyrocyte proliferation is largely known as iodine autoregulation. However, the molecular mechanisms by which iodide modulates thyroid function remain unclear. In this paper, we analyze the transcriptome profile of the rat follicular cell lineage PCCl3 under untreated and treated conditions with 10 (- 3) M sodium iodide (NaI). Serial analysis of gene expression (SAGE) revealed 84 transcripts differentially expressed in response to iodide (p <= 0.001). We also showed that iodide excess inhibits the expression of essential genes for thyroid differentiation: Tshr, Nis, Tg, and Tpo. Relative expression of 14 of 20 transcripts selected by SAGE was confirmed by real-time PCR. Considering the key role of iodide organification in thyroid physiology, we also observed that both the oxidized form of iodide and iodide per se are responsible for gene expression modulation in response to iodide excess.
