More Signs of Neurotoxicity of Surfactants and Flame Retardants - Neonatal PFOS and PBDE 99 Cause Transcriptional Alterations in Cholinergic Genes in the Mouse CNS

Hallgren, Stefan, Fredriksson, Anders, Viberg, Henrik·2015·Environmental Toxicology and Pharmacology

Abstract

Maternally and lactionally transferred persistent organic pollutants may interfere with CNS development. Here, 10-day-old male mice were exposed to single oral doses of PFOS (perflourooctanosulphonate) or PBDE 99 (2,2',4,4',5-penta-bromodiphenyl ether), and examined for changes in cholinergic gene transcription in the CNS 24h and 7 weeks later. 24h after exposure qPCR analyses revealed decreased transcription of nAChR-β2 and AChE in cortex, and increased mAChR-5 in hippocampus of PFOS treated mice. Neonatal PFOS treatment altered spontaneous behaviour at 2 months of age but did not affect gene transcription in adults. At 2 months of age neonatally PBDE 99 treated mice had altered spontaneous behaviour, and cortical transcription of AChE, nAChR-α4, nAChR-β2 and mAChR-5 were elevated. Our results indicate that PFOS and PBDE 99 affects the developing central cholinergic system by altering gene transcription in cortex and hippocampus, which may in part account for mechanisms causing changes in spontaneous behaviour.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Hallgren et al. (2015) found that PFOS decreased transcription of genes encoding proteins essential to cholinergic system functioning in the brain, including acetylcholinesterase (AchE), nicotinic acetylcholine receptor β2 (nAChR-β2), and muscarinic acetylcholine receptor m5 (mAChR-5).

    “In conjunction with altered spontaneous motor activity, Hallgren et al. (2015) found that PFOS decreased transcription of genes encoding proteins essential to cholinergic system functioning in the brain, including acetylcholinesterase (AchE), nicotinic acetylcholine receptor β2 (nAChR-β2), and muscarinic acetylcholine receptor m5 (mAChR-5).”
  • Decreased habituation was observed in mice after exposure to 8.7 mg/kg PFOA or 11.3 mg/kg PFOS, whereas altered spontaneous behavior was observed after exposure to 0.58 mg/kg PFOA or 0.75 mg/kg PFOS.

    “Decreased habituation was observed in the mice after exposure to 8.7 mg/kg PFOA or 11.3 mg/kg PFOS, whereas altered spontaneous behavior was observed after exposure to 0.58 mg/kg PFOA or 0.75 mg/kg PFOS (Johansson et al., 2008; Hallgren et al., 2015).”
  • In inbred male NMRI mice, a single oral exposure of PFOA or PFOS at PND 10 caused a long-lasting hyperactive phenotype at 2 and 4 months of age, characterized by decreased habituation and altered spontaneous behavior.

  • PFAS exposure has been shown to disrupt glutamate, GABA, dopamine, acetylcholine, and serotonin levels.

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.
