In animal studies, Bisphenol A (BPA) adversely impacts development through multiple pathways; yet little is known about mechanisms in humans. We propose to address this gap in our knowledge by using an in vitro cell model system for studying the effects of BPA on human embryonic development. Using a microarray approach, we will measure changes in global gene expression induced by environmentally-relevant BPA doses in a cell colony observed over multiple time points. We will conduct a parallel experiment with physiologically-relevant doses of 17beta-estradiol (E2) to understand to what degree effects are estrogen-dependent.Expected Results:
By identifying and then validating the specific molecular targets altered by BPA exposure at the protein level and in partially-differentiated embryoid bodies, we will gain important information about the mechanisms that underlie BPA induced interference with the earliest events in human development. This information could be used in a tutorial targeted to community groups, clinicians and patients intended to educate and raise awareness on the prevention of harmful chemical exposures during pregnancy.Supplemental Keywords:
