      Kvitne, Kine Eide; Hole, Kristine; Krogstad, Veronica; Wollmann, Birgit Malene Tovik; Wegler, Christine; Johnson, Line Kristin; Hertel, Jens Kristoffer; Artursson, Per; Karlsson, Cecilia; Andersson, Shalini; Andersson, Tommy B.; Sandbu, Rune; Hjelmesæth, Jøran Sture; Skovlund, Eva; Christensen, Hege; Jansson-Löfmark, Rasmus; Åsberg, Anders; Molden, Espen; Robertsen, Ida (European Journal of Clinical Pharmacology;Volume 78, issue 8, Peer reviewed; Journal article, 2022-06-01)
      Purpose Variability in cytochrome P450 3A4 (CYP3A4) metabolism is mainly caused by non-genetic factors, hence providing a need for accurate phenotype biomarkers. Although 4β-hydroxycholesterol (4βOHC) is a promising ...
