    • 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 (Journal article; Peer reviewed, 2022)
      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 ...

    • Digoxin Pharmacokinetics in Patients with Obesity Before and After a Gastric Bypass or a Strict Diet Compared with Normal Weight Individuals 

      Kvitne, Kine Eide; Hovd, Markus; Johnsen, Line Kristin; Wegler, Christine; Karlsson, Cecilia; Artursson, Per; Andersson, Shalini; Sandbu, Rune; Hjelmesæth, Jøran Sture; Skovlund, Eva; Jansson-Löfmark, Rasmus; Christensen, Hege; Åsberg, Anders; Robertsen, Ida (Journal article; Peer reviewed, 2023)
      Background and Objective Several drugs on the market are substrates for P-glycoprotein (P-gp), an efflux transporter highly expressed in barrier tissues such as the intestine. Body weight, weight loss, and a Roux-en-Y ...

    • Gastric Bypass vs Diet and Cardiovascular Risk FactorsA Nonrandomized Controlled Trial 

      Karlsson, Cecilia; Johnsen, Line Kristin; Greasley, Peter; Retterstøl, Kjetil; Hedberg, Jonatan; Hall, Martin; Hawker, Noele; Robertsen, Ida; Havsol, Jesper; Hertel, Jens Kristoffer; Sandbu, Rune; Skovlund, Eva; Olsen, Thomas; Christensen, Hege; Jansson-Löfmark, Rasmus; Andersson, Shalini; Åsberg, Anders; Hjelmesæth, Jøran Sture (Journal article; Peer reviewed, 2024)
      Importance Roux-en-Y gastric bypass (RYGB) is associated with reduced cardiovascular (CV) risk factors, morbidity, and mortality. Whether these effects are specifically induced by the surgical procedure or the weight loss ...

    • Impact of body weight, low energy diet and gastric bypass on drug bioavailability, cardiovascular risk factors and metabolic biomarkers: protocol for an open, non-randomised, three-armed single centre study (COCKTAIL) 

      Hjelmesæth, Jøran; Åsberg, Anders; Andersson, Shalini; Sandbu, Rune; Robertsen, Ida; Johnson, Line Kristin; Angeles, Philip Carlo Soriano; Hertel, Jens Kristoffer; Skovlund, Eva; Heijer, Maria; Ek, Anna-Lena; Krogstad, Veronica; Karlsen, Tor-Ivar; Christensen, Hege Staaland; Andersson, Tommy B; Karlsson, Cecilia (Journal article; Peer reviewed, 2018)
      Introduction: Roux-en-Y gastric bypass (GBP) is associated with changes in cardiometabolic risk factors and bioavailability of drugs, but whether these changes are induced by calorie restriction, the weight loss or surgery ...

    • Impact of type 2 diabetes on in vivo activities and protein expressions of cytochrome P450 in patients with obesity 

      Kvitne, Kine Eide; Åsberg, Anders; Johnson, Line Kristin; Wegler, Christine; Hertel, Jens Kristoffer; Artursson, Per; Karlsson, Cecilia Elisabeth; Andersson, Shalini; Sandbu, Rune; Skovlund, Eva; Christensen, Hege; Jansson-Löfmark, Rasmus; Hjelmesæth, Jøran Sture; Robertsen, Ida (Peer reviewed; Journal article, 2022)
      Previous studies have not accounted for the close link between type 2 diabetes mellitus (T2DM) and obesity when investigating the impact of T2DM on cytochrome P450 (CYP) activities. The aim was to investigate the effect ...

    • Neither Gastric Bypass Surgery Nor Diet-Induced Weight-Loss Affect OATP1B1 Activity as Measured by Rosuvastatin Oral Clearance 

      Hovd, Markus Herberg; Robertsen, Ida; Johnson, Line Kristin; Krogstad, Veronica; Wegler, Christine; Kvitne, Kine Eide; Kringen, Marianne K.; Skovlund, Eva; Karlsson, Cecilia; Andersson, Shalini; Artursson, Per; Sandbu, Rune; Hjelmesæth, Jøran Sture; Åsberg, Anders; Jansson-Löfmark, Rasmus; Christensen, Hege (Peer reviewed; Journal article, 2023)
      Introduction Rosuvastatin pharmacokinetics is mainly dependent on the activity of hepatic uptake transporter OATP1B1. In this study, we aimed to investigate and disentangle the effect of Roux-en-Y gastric bypass (RYGB) and ...

    • Short- and long-term effects of body weight loss following calorie restriction and gastric bypass on CYP3A-activity – a non-randomized three-armed controlled trial 

      Kvitne, Kine Eide; Robertsen, Ida; Skovlund, Eva; Christensen, Hege Staaland; Krogstad, Veronica; Wegler, Christine; Angeles, Philip Carlo Soriano; Wollmann, Birgit Malene Tovik; Hole, Kristine; Sandbu, Rune; Artursson, Per; Karlsson, Cecilia; Andersson, Shalini; Andersson, Tommy B.; Hjelmesæth, Jøran; Jansson-Löfmark, Rasmus; Åsberg, Anders (Journal article; Peer reviewed, 2021)
      It remains uncertain whether pharmacokinetic changes following Roux-en-Y gastric bypass (RYGB) can be attributed to surgery-induced gastrointestinal alterations per se and/or the subsequent weight loss. The aim was to ...
