1 A role for the pregnane X receptor in flucloxacillin-induced liver injury. Floxacillin nuclear receptor subfamily 1 group I member 2 Homo sapiens
2 There is some evidence that flucloxacillin is a human pregnane X receptor (PXR) agonist. Floxacillin nuclear receptor subfamily 1 group I member 2 Homo sapiens
3 There is some evidence that flucloxacillin is a human pregnane X receptor (PXR) agonist. Floxacillin nuclear receptor subfamily 1 group I member 2 Homo sapiens
4 This study was designed to investigate the relevance of PXR to flucloxacillin toxicity and to identify genes changing in expression in response to flucloxacillin. Floxacillin nuclear receptor subfamily 1 group I member 2 Homo sapiens
5 The ability of flucloxacillin to act as a PXR agonist was investigated with reporter gene experiments. Floxacillin nuclear receptor subfamily 1 group I member 2 Homo sapiens
6 Using a luciferase-everted repeat separated by 6 base pairs element construct, we confirmed that flucloxacillin was a PXR agonist. Floxacillin nuclear receptor subfamily 1 group I member 2 Homo sapiens
7 We found a difference in the distribution of a PXR polymorphism (rs3814055; C-25385T) between flucloxacillin DILI cases and controls with the CC genotype associated with an increased risk of disease (odds ratio = 3.37, 95% confidence interval = 1.55-7.30, P = 0.0023). Floxacillin nuclear receptor subfamily 1 group I member 2 Homo sapiens
8 CONCLUSION: Flucloxacillin is a PXR agonist at pharmacologically relevant concentrations, and a functionally significant upstream PXR polymorphism is a risk factor for flucloxacillin-induced DILI. Floxacillin nuclear receptor subfamily 1 group I member 2 Homo sapiens
9 CONCLUSION: Flucloxacillin is a PXR agonist at pharmacologically relevant concentrations, and a functionally significant upstream PXR polymorphism is a risk factor for flucloxacillin-induced DILI. Floxacillin nuclear receptor subfamily 1 group I member 2 Homo sapiens
