Comparison of effects of Iodine-deficiency and perchlorate on thyroid

ABSTRACT: Perchlorate, which is a ubiquitous and persistent ion, competitively interferes with iodide accumulation in the thyroid, causing iodine deficiency, which may result in reduced thyroid hormone synthesis and secretion. Human studies suggest that perchlorate presents very little risk in healthy individuals; however, the precautionary principle demands that the sensitive populations of iodine deficient adults and mothers require extra consideration. In an attempt to determine if the effects on gene expression were similar, we compared the thyroidal effects of perchlorate (10 mg/kg) treatment for 14 days in drinking water with those caused by 8 weeks of Iodine-deficiency in rats. The thyroids were collected (N=3 each group) and total mRNA was analyzed using the Affymetrix Rat Genome 230 2.0 Gen
