Effect of insulin on iodide uptake in mouse mammary gland explants

Studies were carried out primarily to assess the role of insulin in regulating iodide uptake in the mammary gland. Using cultured mammary gland explants from virgin and pregnant mice (12-14 days into gestation), insulin (1 mug/ml) was shown to stimulate iodide uptake after a 2-day exposure period. The effect of insulin was manifested by itself, as well as in the presence of cortisol and prolactin. Optimal iodide uptake was observed when tissues were treated with all three lactogenic hormones (insulin, cortisol, and prolactin). In a time-course experiment, the effect of insulin alone was initially observed after a 10-hr treatment; the effect was maintained for 30 hr. In dose-response studies, 1 ng/ml insulin elicited a significant effect after 24 hr in culture; a maximal effect was achieved with 50-100 ng/ml insulin. The optimal cortisol concentration for a maximum stimulation of iodide uptake was 10(-7)M. In a quantitative Western blot analysis employing an antibody to the sodium-iodide symporter, insulin stimulated an upregulation of the transporter protein after a 4-, 8-, or 20-hr treatment with insulin. Perchlorate and thiocyanate abolished the insulin effect on iodide uptake, further suggesting that the insulin response occurs via a stimulation of the sodium-iodide symporter. Clearly, insulin is an important and essential hormone in the lactogenic hormone complex for regulating iodide uptake in the mammary gland, but maximal expression of iodide uptake is only expressed when all three lactogenic hormones are present.

Synthesis of new nitrogen-containing perfluoroalkyl iodides

Perfluoro(dimethylamino)-, perfluoro(diethylamino)-, perfluoro(1-pyrrolidinyl)-, perfluoromorpholino-, perfluoropiperidino- and perfluoropropoxy-substituted perfluoroalkyl iodides were synthesized directly by the reaction of the corresponding perfluoroacyl fluorides with lithium iodide in high yield. Under controlled reaction conditions, it was possible to synthesize either iodo-perfluoroacyl fluorides or perfluoroalkylidene diiodides by the reaction of perfluoro (alkanedioyl) difluorides with lithium iodide. Perfluoro(alpha-alkylamino-substituted alkyl) iodides may be good candidates for the media of solar-pumped lasers. (C) 1997 Elsevier Science S.A.

Rhodium-Catalyzed Generation of Anhydrous Hydrogen Iodide: An Effective Method for the Preparation of lodoalkanes

The preparation of anhydrous hydrogen iodide directly from molecular hydrogen and iodine using a rhodium catalyst is reported for the first time. The anhydrous hydrogen iodide generated was proven to be highly active in the transformations of alkenes, phenyl aldehydes, alcohols, and cyclic ethers to the corresponding iodoalkanes. Therefore, the present methodology not only has provided convenient access to anhydrous hydrogen iodide but also offers a practical preparation method for various iodoalkanes in excellent atom economy.

Formation of methyl iodide in the radiolysis of aqueous cesium iodide and acetic acid solutions

Volatile compounds of radioactive iodine, including methyl iodide, are released into the environment in the cases of serious accidents at nuclear power plants. The aim of this study was to find a conceivable mechanism of the radiation-chemical formation of methyl iodide in aerated aqueous solutions of cesium iodide and acetic acid. This provides the basis for subsequent investigations aimed at preventing the formation of methyl iodide. The radiation-chemical yield of methyl iodide formation in 10(-3) M CsI solutions containing CH3COOH (0.1 mol/l) decreased with increasing the pH. This fact is primarily explained by a decrease in the steady-state concentration of molecular iodine with increasing the pH. An increase in the pH of irradiated solutions up to pH greater than or equal to 9 was found not only to prevent the formation of methyl iodide but also to enhance its radiation-chemical degradation.

Growth Stimulation of Iodide-Oxidizing alpha-Proteobacteria in Iodide-Rich Environments

alpha-Proteobacteria that can oxidize iodide (I-) to molecular iodine (I-2) have only been isolated from iodide-rich natural and artificial environments, i.e., natural gas brine waters and seawaters supplemented with iodide, respectively. To understand the growth characteristics of such iodide-oxidizing bacteria (IOB) under iodide-rich environments, microcosms comprising natural seawater and 1 mM iodide were prepared, and the succession of microbial communities was monitored by culture-independent techniques. PCR-denaturing gradient gel electrophoresis and 16S rRNA gene sequence analysis showed that bacteria closely related with known IOB were predominant in the microcosms after several weeks of incubation. Quantitative PCR analysis targeting specific 16S rRNA gene regions of IOB showed that the relative abundance of IOB in the microcosms was 6-76% of the total bacterial population, whereas that in natural seawater was less than 1%. When 10(3) cells mL(-1) of IOB were inoculated into natural seawater supplemented with 0.1-1 mM iodide, significant growth (cell densities, 10(5)-10(6) cells mL-1) and I-2 production (6-32 mu M) were observed. Interestingly, similar growth stimulation occurred when 12-44 mu M of I-2 was added to seawater, instead of iodide. IOB were found to be more I-2 tolerant than the other heterotrophic bacteria in seawater. These results suggest that I-2 plays a key role in the growth stimulation of IOB in seawater. IOB could potentially attack other bacteria with I-2 to occupy their ecological niche in iodide-rich environments.

Iodide sensitizes genetically modified non-small cell lung cancer cells to ionizing radiation

While external ionizing radiation has been used for treating non-small cell lung cancer (NSCLC), improved efficacy of this modality would be an important advance. Ectopic expression of the sodium iodide symporter (NIS) and thyroperoxidase (TPO) genes in NSCLC cells facilitated concentration of iodide in NSCLC cells, which markedly induced apoptosis in vitro and in vivo. Preincubation of the NIS/TPO-modified NSCLC cells in iodide followed by ionizing radiation generates bystander tumoricidal effects and potently enhances tumor cell killing. This iodide-induced bystander effect is associated with enhanced gap junction intercellular communication (GJIC) activity and increased connexin-43 (Cx43) expression. Thus, iodide may serve as an enhancer to markedly improve the efficacy of radiation therapy in combined therapeutic modalities.
