Next Generation Sequencing to assess pesticides capacity in vitro to act as agonists/antagonists of the thyroid hormone nuclear receptors


ABSTRACT: We combined in vitro tests to fully assess the capacity of pesticides to act as thyroid hormone disruptors (THD). Pesticides which were active in these tests were selected for a transcriptome analysis of neural cells. We took advantage of this technique to decipher what were the transcriptomic effects of these chemical in vitro. We also compared the expression of thyroid hormone responsive genes in presence or absence of the pesticides to determine if the transcriptomic changes could impact thyroid hormone receptor signaling. Although some pesticides elicit a cellular response, which sometimes interferes with thyroid hormone signaling, we found no evidence that they can act as TRα1 agonists or antagonists. We conclude that their neurodevelopmental toxicity in mammals is not explained by an alteration of the neural cell response to thyroid hormone.
