Perfluorooctane Sulfonate Induces Neuronal Vulnerability by Decreasing GluR2 Expression

Abstract

Perfluorooctane sulfonate (PFOS) is a persistent environmental contaminant. Although studies have described PFOS-induced neurotoxicity in animal brains and neuronal cells, the molecular mechanisms of PFOS-induced neurotoxicity based on the distribution properties, especially during developmental periods, have not been clarified. To clarify the mechanisms of PFOS-induced neuronal vulnerability during developmental periods, we examined changes in glutamate receptor 2 (GluR2) expression and related neurotoxicity in PFOS-treated primary cortical neurons and neonatal rat brains. Exposure of cortical neurons to 1 μM PFOS for 9 days resulted in decreased α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunit GluR2 expression, which subsequently enhanced vulnerability to glutamate by increasing intracellular Ca 2+ concentrations. The brain-plasma ratio of PFOS in pups was approximately five times higher than that in dams, although there were no differences in liver-plasma ratio between dams and pups. GluR2 expression in pup cerebral cortex decreased after exposure to 2.0 mg/kg PFOS, and kainic acid induced histopathological abnormalities in PFOS-exposed pups. Our findings suggest that decreased neuronal GluR2 expression is involved in PFOS-induced neurotoxicity, especially during the fetal and neonatal periods.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
