1) Impact of PFOA, PFOS, replacement PFAS, and human-relevant PFAS mixtures on cholesterol homeostasis by using human hepatocyte cell models. 2) A broad set of in vitro bioassays will be employed to identify effects of PFAS on cholesterol synthesis and metabolism including relevant molecular and cellular endpoints such as nuclear receptor activation, gene expression analysis, activity of relevant cholesterol and bile acid transporters, and determination of cholesterol and relevant metabolites. 3) Link the in vitro data to results of ESR9 regarding gene expression and metabolomic profiles altered by PFAS in human blood samples.
VU/Hamers, Leonards (M13, 4w) to get trained in metabolomic techniques. KI/Håkansson (M31, 4w) to integrate in vitro toxicity profiles into AOPs. 1-day visits to a local wastewater treatment facility (Svenskt Vatten; M12 after ATC3) and UFZ/Berger (after ATC6 in M24).
