The pharmacological management of MetS often involves polypharmacy, making it essential to understand how drug-metabolising enzymes, transporters, transcription factors and other proteins involved are affected under different metabolic conditions. This study investigated the relative mRNA expression of key hepatic and intestinal genes involved in drug metabolism, including <i>Cyp1a2</i>, <i>Cyp3a23</i>, <i>Cyp2d1</i>, <i>Cyp2c11</i>, <i>Cyp2c6</i>, <i>Cyp2e1</i>, <i>Cyp7a1</i>, <i>Cyp2b1</i>, <i>Cyp2a1</i>, <i>Abcg5</i>, <i>Abcg8</i>, <i>Abcb1</i>, <i>Nr1i3</i>, <i>Nr1i2</i>, <i>Ahr</i>, <i>Gsta1</i> and <i>Comt</i>, in four nonobese rat models of MetS: hereditary hypertriglyceridaemic (HHTg), spontaneously hypertensive rat (SHR), SHR expressing transgenic human C-reactive protein (SHR-CRP), and bilaterally ovariectomised Wistar (W-OVX), compared to Wistar controls. Gene expression was quantified by RT–PCR with data normalised using the <sup>ΔΔ</sup>Ct method. Between the models studied, measurements showed significant differences in the liver. The upregulation of <i>Cyp2c6</i> and <i>Cyp3a23</i> was observed only in SHR; upregulated <i>Cyp2d1</i> was found in SHR as well as in HHTg rats. The downregulated <i>Cyp1a2</i> was measured in a condition of hypertriglyceridemia, postmenopause or hypertension. These findings highlight model-specific alterations in gene expression that may affect drug metabolism and interactions. The HHTg may be, in particular, a suitable model for preclinical studies focusing on intestinal drug–drug interactions in MetS-related conditions.</p>","PeriodicalId":8733,"journal":{"name":"Basic & Clinical Pharmacology & Toxicology","volume":"137 2","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/bcpt.70075","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
