Développement de méthodes de référence pour les biomarqueurs du bilan lipidique : application au contrôle qualité en biologie clinique
2013
Reliable measurements in medical biology are essential for early screening and appropriate follow-up of patients. Ensuring metrological traceability of clinical measurements to higher order reference methods or certified reference materials enables to obtain comparable results over time and between different laboratories that could use different methods to quantify the same biomarker.In this study, reference methods were developed and validated for lipid profile biomarkers (total cholesterol, triglycerides, HDL-C, and LDL-C). Their value added in proficiency testing schemes was demonstrated against consensus mean. They were also used to characterize a certified reference material (CRM) that…
Etude du rôle du récepteur nucléaire CAR, Constitutive Androstane Receptor, dans le métabolisme des lipides et la susceptibilité à l'athérosclérose
2011
The Constitutive Androstane Receptor (CAR) belongs to the subfamily of nuclear receptors NR1. Initially described as an orphan receptor, CAR is activated by a large number of exogenous molecules and acts as a xenosensor. The activation of CAR by these ligands stimulates transcription of phase I, II and III enzymes required for the detoxification and elimination of xenobiotics. Furthermore CAR is also involved in the metabolism of endogenous molecules such as bile acids, bilirubin or thyroid hormones. CAR has recently been the subject of numerous independent studies that have highlighted his involvement in major metabolic pathways including gluconeogenesis, lipogenesis and lipoprotein metabo…
