    Low-dose exposure to PFAS alters cellular metabolism despite minimal intracellular accumulation.

  • 2

    The study utilized a long-term cell culture model to assess the effects of PFOA and PFOS on human epithelial cells.

  • 3

    PFOS levels increased rapidly within 24 hours but stabilized, while PFOA remained below detection limits throughout.

  • 4

    Transcriptomic and lipidomic analyses revealed changes in oxidative stress pathways and lipid metabolism due to PFAS exposure.

  • 5

    PFAS toxicity may arise from interactions with cellular membranes rather than sustained intracellular accumulation.

The Missing Piece in the Dark Metabolome Puzzle?

Microdroplets formed during electrospray ionization may trigger chemical reactions that help explain a substantial portion of the “dark metabolome” – though some researchers question their relevance under typical metabolomics conditions
