Regulation of drug transporter gene expression by nuclear receptors.
Pregnane X receptor (PXR) and constitutive androstane receptor (CAR) are key regulators of xenobiotic-inducible cytochrome P450 gene expression. Whereas much is known about their role in regulating drug metabolism, little is known regarding their role in regulating drug transport in vivo. Wild-type mice and mice lacking PXR (PXR-KO) were used to examine the inducible expression of two drug tran...
متن کاملMetabolic Regulation by Nuclear Receptors
Howard Hughes Medical Institute, Salk Institute for Biological Studies, 10010 North Torrey Pines Road, La Jolla, CA 92037, USA e-mail: [email protected] Abstract Nuclear receptors (NRs) are a large family of ligand-dependent transcriptional regulators that control development, reproduction, metabolism, and inflammation. Cognate ligands include fatty acids, bile acids, steroids, vitamins A and D, a...
متن کاملNuclear receptors as targets for drug development: regulation of cholesterol and bile acid metabolism by nuclear receptors.
Nuclear receptors are ligand-dependent transcription factors that recently have been shown to play important roles in the metabolism of cholesterol and bile acids. Cholesterol homeostasis is maintained by de novo synthesis, absorption from diet, catabolism to bile acids and other steroids, and excretion into bile. Dysregulation of this mechanism leads to atherosclerosis and its life-threatening...
متن کاملNuclear receptors as drug targets: new developments in coregulators, orphan receptors and major therapeutic areas.
Nuclear receptors (NRs) are ideal targets for drug discovery. Not only do they control a myriad of biological and disease processes, but they are also regulated by small lipophilic molecules that can be easily exchanged with a drug of choice. All 48 of the NR genes in the human genome have been identified, many of their structures have been solved and their ligands identified. Their mechanism o...
متن کاملMolecular mechanisms of transcriptional regulation by nuclear receptors. Perspectives for therapeutic implications.
Nuclear receptors are ligand-regulated transcription factors that evolved from an ancestral orphan receptor into a highly diverse family present throughout the entire animal kingdom. They encompass receptors for steroid and non-steroid hormones, vitamins and metabolic intermediates. These receptors signal through endocrine, paracrine, autocrine and intracrine networks to regulate multiple aspec...
