The Effects of Perchlorate on Thyroidal Gene Expression are Different from the Effects of Iodide Deficiency

Perchlorate (ClO4 −), which is a ubiquitous and persistent ion, competitively interferes with iodide (I) accumulation in the thyroid, producing I deficiency (ID), which may result in reduced thyroid hormone synthesis and secretion. Human studies suggest that ClO4 − presents little risk in healthy individuals; however, the precautionary principle demands that the sensitive populations of ID adults and mothers require extra consideration. In an...
