Correlations between 4β-hydroxycholesterol and hepatic and intestinal CYP3A4: protein expression, microsomal ex vivo activity, and in vivo activity in patients with a wide body weight range
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 ... -
Effects of a Novel UGT2B Haplotype and UGT1A4*3 Allele Variants on Glucuronidation of Clozapine In vivo
Smith, Robert Løvsletten; Wollmann, Birgit Malene Tovik; Kausberg, Marianne; Mæland, Sondre; Tveito, Marit; O'Connell, Kevin Sean; Molden, Espen; Kringen, Marianne K. (Current drug metabolism;Volume 23, Issue 1, Peer reviewed; Journal article, 2022)Background: Glucuronidation is an important metabolic pathway of clozapine (CLZ), but the impact of various uridine 5'diphospho-glucuronosyltransferases (UGT) polymorphisms on the exposure and metabolism of CLZ in vivo is ... -
Evidence for solanidine as a dietary CYP2D6 biomarker: Significant correlation with risperidone metabolism
Wollmann, Birgit Malene Tovik; Smith, Robert Løvsletten; Kringen, Marianne K.; Ingelman-Sundberg, Magnus; Molden, Espen; Størset, Elisabet (Peer reviewed; Journal article, 2023)Aims: The extensive variability in cytochrome P450 2D6 (CYP2D6) metabolism is mainly caused by genetic polymorphisms. However, there is large, unexplained variability in CYP2D6 metabolism within CYP2D6 genotype subgroups. ... -
Prediction of CYP2D6 poor metabolizers by measurements of solanidine and metabolites—a study in 839 patients with known CYP2D6 genotype
Wollmann, Birgit Malene Tovik; Størset, Elisabet; Kringen, Marianne K.; Molden, Espen; Smith, Robert Løvsletten (Peer reviewed; Journal article, 2023)Purpose Poor metabolizers (PMs) of the highly polymorphic enzyme CYP2D6 are usually at high risk of adverse effects during standard recommended dosing of CYP2D6-metabolized drugs. We studied if the metabolism of solanidine, ...
