Perfluoroalkylated Compounds Induce Cell Death and Formation of Reactive Oxygen Species in Cultured Cerebellar Granule Cells

Abstract

The present communication investigates the effects of different perfluoroalkylated compounds (PFCs) on formation of reactive oxygen species (ROS) and cell death in cultured cerebellar granule cells. This allows direct comparison with similar effects found for other environmental contaminants like polychlorinated biphenyls and brominated flame-retardants. The increase in ROS formation and cell death was assayed using the fluorescent probe 2,7-dichlorofluorescin diacetate (DCFH-DA) and the trypan blue exclusion assay. The effects of the PFCs were structure dependent. Cell death was induced at relatively low concentrations by perfluorooctyl sulfonate (PFOS), perfluorooctane sulfonylamide (PFOSA) and the fluorotelomer alcohol 1H, 1H, 2H, 2H-perfluorodecanol (FTOH 8:2) with EC(50)-values of 62 ± 7.6, 13 ± 1.8 and 15 ± 4.2 μM (mean ± SD) respectively. PFOS, perfluorooctanoic acid (PFOA) and PFOSA induced a concentration dependent increase in ROS formation with EC(50)-values of 27 ± 9.0, 25 ± 11 and 57 ± 19μM respectively. Reduced cell viability and ROS formation were observed at concentration level close to what is found in serum of occupationally exposed workers. The effect of PFCs on ROS formation and cell viability was compared with other halogenated compounds and future investigations should emphasize effects of mixtures and how physical chemical properties of the compounds influence their toxicity.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Although actin filament remodeling has only been demonstrated in response to PFOS exposure, several other in vitro studies have demonstrated the ability of PFOS, PFOA, and PFOSA to generate reactive oxygen species in neurons and astrocytes.

    “Whereas this actin filament remodeling has only been demonstrated in response to PFOS exposure, several other in vitro studies have also demonstrated the ability of PFOS, PFOA, and PFOSA, to generate ROS in neurons and astrocytes (Lee et al., 2012; Reistad et al., 2013; Chen et al., 2014; Li Z. et al., 2017).”

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.
