Epidermal Growth Factor Receptor Signaling Disruption by Endocrine and Metabolic Disrupting Chemicals.

ABSTRACT: The purpose of this study is to identify an environmentally relevant shared receptor target for endocrine and metabolism disrupting chemical pollutants. A feature of the tested chemicals was that they induced Cyp2b10 in vivo implicating activation of the constitutive androstane receptor (CAR). Recent studies suggest that these compounds could be indirect CAR activators via epidermal growth factor receptor (EGFR) inhibition. Assays included a CAR activity reporter assay, EGF endocytosis assay, and EGFR phosphorylation assay. Docking simulations were used to identify putative binding sites for environmental chemicals on the EGFR. Whole-weight and lipid-adjusted serum mean pollutant exposures were determined using data from the National Health and Examination Survey (NHANES) and compared with
