Perfluorooctanesulfonic acid (PFOS) disrupts cadherin-16 in the developing rat thyroid gland.

Perfluorooctanesulfonic acid (PFOS) can disrupt the thyroid hormone (TH) system in rodents, potentially affecting perinatal growth and neurodevelopment. Some studies also suggest that gestational exposure to PFOS can lead to lower TH levels throughout life, indicating that PFOS may compromise thyroid gland development. To address this question, we utilized a rat thyroid gland culture system to study direct effects of PFOS on the developing thyroid.
