Cross-species toxicogenomic analyses and phenotypic anchoring in response to groundwater low-level pollution.

Background: Comparison of toxicogenomic data facilitates the identification of deregulated gene patterns and maximizes health risk prediction in human.

Results: Here, we performed phenotypic anchoring on the effects of acute exposure to low-grade polluted groundwater using mouse and zebrafish. Also, we evaluated two windows of chronic exposure in mouse, starting in utero and at the end of lactation.

Bisphenol A interferes with thyroid specific gene expression.

Bisphenol A (BPA) is an endocrine-disrupting chemical that leads to low-dose human exposure due to its ability to leach from chemically derived products, as polycarbonate plastics and epoxy resin. In addition to its known xeno-endocrine action, BPA exerts a wide range of metabolic effects. Despite the documented BPA exposure outcomes on synthesis of thyroid hormones, there are not any data available on its actions on the thyroid follicular cells, site of synthesis of the thyroid hormones.
