Congenital goitrous hypothyroidism is caused by dysfunction of the iodide transporter SLC26A7

Iodide transport and storage in the thyroid follicles is crucial for thyroid hormone synthesis. Pendrin, the iodide exporter that transports iodide to thyroid follicles, is responsible for Pendred syndrome, a disorder characterized by congenital hypothyroidism and hearing loss. However, thyroid hormone levels are basically normal in patients with Pendred syndrome, indicating the presence of another unknown iodide transporter. Here, we show that SLC26A7 is a novel iodide transporter in the thyroid. We observe that SLC26A7 is specifically expressed in normal thyroid tissues and demonstrate its function in iodide transport. Using whole-exome sequencing, we also find a homozygous nonsense mutation in SLC26A7 (c.1498 C > T; p.Gln500Ter) in two siblings with congenital goitrous hypothyroidism. The mutated SLC26A7 protein shows an abnormal cytoplasmic localisation and lacks the iodide transport function. These results reveal that SLC26A7 functions as a novel iodide transporter in the thyroid and its dysfunction affects thyroid hormonogenesis in humans and causes congenital goitrous hypothyroidism.

Acyl Iodides in Organic Synthesis. Reaction of Acetyl Iodide with Thiols

The direction of reactions of acetyl iodide with aliphatic, aromatic, and heterocyclic thiols is determined by the thiol acidity and steric factors. Acetyl iodide reacted with aliphatic thiols, including trialkylsilyl-substituted derivatives R(CH2)(n)SH (R = Me, n = 3; R = Me3Si, n = 3; R = Et3Si, n = 2), to give the corresponding ethanethioates R(CH2)(n)SCOMe. Benzenethiol was oxidized with acetyl iodide to diphenyl disulfide. The reaction of acetyl iodide with 2-sulfanylethanol afforded 2-(2-iodoethyldisulfanyl)ethyl acetate as a result of three consecutive-parallel processes: acylation, iodination, and oxidation of the initial compound. 1,3-Benzothiazole-2-thiol reacted with acetyl iodide only at the nitrogen atom to give quaternary salt, whereas the SH group remained intact.

Iodide transport in lactating rat mammary tissue via a pathway independent from the Na+/I- cotransporter: Evidence for sulfate/iodide exchange

Although it is beyond doubt that mammary cells accumulate iodide via a Na+-dependent transport mechanism, it is not clear if this is the only pathway for iodide transport in mammary tissue. In view of this, experiments were designed to test for the presence of an anion-exchange pathway which could mediate the transport of iodide into mammary cells; thus, the effect of external iodide on sulfate efflux from rat mammary tissue has keen investigated. Iodide trans-stimulated sulfate efflux from mammary tissue explants in a dose-dependent manner: 0.1, 1.0 and 10.0 mM iodide stimulated the fractional release of iodide by 56 +/- 2,2, 166.5 +/- 17.5, and 302.9 +/- 29.8%, respectively. The stimulation of sulfate efflux by external iodide was completely inhibited by DIDS (4.4′-diisothiocyanatostilbene 2,2′-disulfonic acid). Perchlorate (1 mM) also trans-stimulated sulfate efflux in a manner that was inhibited by DIDS, Furthermore, iodide trans-accelerated sulfate efflux from rat mammary acini via a DIDS-sensitive mechanism. The results are consistent with the presence of a DIDS-sensitive anion-exchange mechanism which can accept iodide as a substrate. It appears that the iodide-sulfate exchange mechanism is independent from the sodium-dependent iodide transporter given that sulfate is not a substrate of the latter system. The iodide-sulfate exchanger may operate in parallel with the sodium-dependent iodide transporter to mediate iodide uptake into mammary cells. (C) 2001 Academic Press.

Glycosyl iodides are highly efficient donors under neutral conditions

Glycosyl iodides have been prepared and subjected to glycosylation under neutral conditions. The reactions are highly efficient, giving alpha glycosides even with sterically demanding glycosyl accepters. Glucosyl iodides react with allyl alcohol slowest and require refluxing conditions. Galactosyl iodides are intermediate in reactivity, providing the allyl glycoside in 3 h at room temperature, whereas glycosylation of fucosyl iodides occurs in less than 1 h under similar conditions. The scope and limitations of the reactions were demonstrated with a variety of accepters, including an anomeric hydroxyl group, to give trehalose analogs, beta-Selective glycosylation of glucosyl iodides, in the absence of C-2 participation, could be achieved by simply changing the solvent from benzene to acetonitrile.

CLINICAL-EVALUATION OF THE IODIDE CREATININE RATIO OF CASUAL URINE SAMPLES AS AN INDEX OF DAILY IODIDE EXCRETION IN A POPULATION STUDY

To assess the daily iodine intake in a population study, we have compared the validity and degree of reliability of the urine iodide/creatinine ratios and iodide concentrations of casual samples as a representative index of daily urine iodide excretion. The morning urine samples were obtained from apparently healthy 2,956 men and 1,182 women residing in Sapporo, Japan, and urine iodide was measured by an iodide selective electrode. The iodide/creatinine ratio was higher in women than in men, increasing more steeply with age in women than in men, due to a concomitant decrease in the urine creatinine level with age. The iodide concentration showed no age-related change. Similarly the daily urine iodide excretion measured in 22 control subjects by collecting 24-h urine specimens did not vary with age, while the iodide/creatinine ratio of these subjects increased with age. The correlation coefficient(r) of the iodide concentration with daily iodide excretion in the 95 observations of the 22 subjects was 0.832 (P<0.001), higher than that of iodide/creatinine ratio with daily iodide excretion (0.699, P<0.001). The 95% range of the iodide concentration in morning urine samples in the population (n=4,138) was 9.0-70.3 mumol/L with a mean of 27.1 mumol/L. These results indicate that in a population with a large difference in age, an age-associated decrease in the urine creatinine concentration should be considered for the evaluation of the iodide/creatinine ratio and the measurement of the iodide concentration in morning spot urine sample may also be useful for the estimation of daily iodide excretion, and that the Japanese subjects here have a high iodine intake, with considerable variation.

Determination of iodide and iodate by ion chromatography with postcolumn reaction and UV/visible detection

Iodide and iodate can be determined by two new methods using anion-exchange chromatography with postcolumn reaction and UV/visible detection. Iodide is determined as IBr2- at 249 mn. Iodate is determined as I-3(-) at 288 nm. The analyses can be run completely automatically and do not require any sample pretreatment, The detection limits for iodide and iodate are 0.1 mu g/L. The methods have been successfully applied to determine iodide and iodate in several mineral waters and in drinking water as well as for the determination of iodide in table salt.

Oxidative Addition of Alkenyl and Alkynyl Iodides to a Au-I Complex

The first isolated examples of intermolecular oxidative addition of alkenyl and alkynyl iodides to Au-I are reported. Using a 5,5 ‘-difluoro-2,2 ‘-bipyridyl ligated complex, oxidative addition of geometrically defined alkenyl iodides occurs readily, reversibly and stereospecifically to give alkenyl-Au-III complexes. Conversely, reversible alkynyl iodide oxidative addition generates bimetallic complexes containing both Au-III and Au-I centers. Stoichiometric studies show that both new initiation modes can form the basis for the development of C-C bond forming cross-couplings.

Anodic differential pulse voltammetric analysis of iodide with a cinchonine-modified carbon paste electrode

The stripping voltammetric determination of iodide ions has been completed using a cinchonine modified carbon paste electrode. Iodide ions were deposited onto a carbon paste electrode containing cinchonine via the ion pairing reaction in an acidic medium. The oxidation peak potential of the iodide ion is +0.65 V. The analytical conditions for the determination of the iodide ion were optimized by cyclic voltammetry. The optimal composition of CMCPE and pH of the solution on the deposition of iodide are 40% (w/w) and 2.15, respectively. Differential pulse voltammetry was applied to determine the calibration plot and detection limit. The detection limit was 8.0 x 10(-8) M for 20 min of deposition time and relative standard deviation (5 determinations) was +/- 4.2% at a 7.0 x 10(-7) M iodide solution. The interferences of anions anions and cations were investigated. The thiosulfate ion interferes with the oxidation current of the iodide ion by about 12%. Cl-, Br-, SCN-, C2O42-, ClO4-, NO3-, Co2+, Fe(CN)(6)(3-), Ni2+, Cu2+, Cd2+, Pb2+, and Hg2+ do not interfere with the determination for the iodide ion. The applicability of the CMCPE: tcs the determination of iodide in a disinfectant has also been investigated.

Prolactin stimulation of iodide uptake into mouse mammary gland explants

These studies show that prolactin (PRL) stimulates iodide accumulation in cultured mouse mammary tissues. This effect of PRL likely causes the elevated concentration of iodide that occurs in the milk of a number of species. In time course studies, an initial effect of PRL occurred after 4 h, whereas a maximum two- to threefold increase was observed after 24 h. In dose-response studies, 1 ng/ml PRL elicited a significant response, whereas PRL concentrations >5 ng/ml stimulated maximum responses. Other lactogenic hormones, including human growth hormone (GH) and human placental lactogens, also stimulated iodide uptake, whereas nonlactogenic substances, including bovine GH, bovine serum albumin, and thyroid-stimulating hormone, were without effect. PRL had no effect on iodide uptake into fat cells. In further studies it was shown that PRL stimulates iodide incorporation into macromolecules in a 10% trichloroacetic acid precipitable tissue fraction as well as in a pH 4.6 isoelectric precipitate. The findings from these studies suggest that PRL may stimulate both the accumulation of free iodide in milk and iodide incorporation into milk proteins.
