Transcriptomic modifications of the thyroid gland upon exposure to phytosanitary-grade fipronil: Evidence for the activation of compensatory pathways

, 2020
International audienceFipronil is a phenylpyrazole insecticide used for the control of a variety of pest for domestic, veterinary and agricultural uses. Fipronil exposure is associated to thyroid disruption in the rat.

Fipronil-induced disruption of thyroid function in rats is mediated by increased total and free thyroxine clearances concomitantly to increased activity of hepatic enzymes

, 2009
Fipronil is a widely used phytosanitary product and insecticide for pets. In the rat, fipronil can disrupt thyroid function by decreasing plasma concentrations of total thyroxine (T4) likely through increased T4 clearance.

Glucocorticoid-like pathogenic mechanisms of fipronil metabolites and parthenolide-based intervention strategies

Ecotoxicology and Environmental Safety
Fipronil (FIP), a widely used phenylpyrazole insecticide, biotransforms into metabolites (FIP-desulfinyl, FIP-sulfone, FIP-sulfide) with enhanced toxicity, persistence, and bioaccumulation potential that pose substantial human health risks.
