This dataset was generated to support parameterization of a larval amphibian thyroid axis computational model. Specifically, plasma iodine levels were determined not only to inform a concentration value for model parameter specification in the model, but also to support the notion that aquatic and terrestrial species should be considered substantially different with regard to circulating iodide levels. Other computational model physical parameters were informed by evaluating Xenopus laevis thyroid gland histological images for morphological features including thyroid follicular cell numbers and areas.

This data set is a dose response analysis of two thyroid hormone synthesis disruptors in adult male rats. Data included serum and thyroid gland concentrations of the two chemicals tested, propylthiouracil and methimazole, as well as serum and thyroid gland hormone concentrations. These data were critical for developing a model linking highthroughput assay data on synthesis inhibition to make predictions of thyroid hormone in serum.

The objective of this study was to develop a medium-throughput organotypic screening assay comprised of reconstructed human thyroid microtissues to quantitatively evaluate the disruptive effects of chemicals on TH production and secretion. Primary human thyroid cells procured from qualified euthyroid donors were analyzed for retention of NK2 homeobox 1 (NKX2-1), Keratin 7 (KRT7), and Thyroglobulin (TG) expression by high-content image analysis to verify enrichment of follicular epithelial cells. A direct comparison of two-dimensional (2D) and three-dimensional (3D) 96-well culture formats was employed to characterize the morphology, differential gene expression, TG production, and TH synthesis over the course of 20 days.
