Pregnane X receptor and human malignancy. [PDF]

, 2013
Pregnane X Receptor (PXR) is a member of the nuclear receptor superfamily, expressed in liver, intestine and other tissues. PXR exerts transcriptional regulation by binding to its DNA response elements as an heterodimer with Retinoid X Receptor (RXR ...

Deficiency of PXR decreases atherosclerosis in apoE-deficient mice

Journal of Lipid Research, 2011
The pregnane X receptor (PXR, also known as SXR) is a nuclear hormone receptor activated by xenobiotics as well as diverse sterols and their metabolites.

Effect of carbamazepine on the pharmacokinetics of vepdegestrant, a PROteolysis TArgeting Chimera estrogen receptor degrader, in healthy adults

British Journal of Clinical Pharmacology, Volume 92, Issue 7, Page 2183-2192, July 2026.
Aim To evaluate the effects of carbamazepine, a strong cytochrome P450 (CYP)3A4 inducer, on the pharmacokinetics and safety of vepdegestrant, a PROteolysis TArgeting Chimera estrogen receptor degrader. Methods This was a phase 1, open‐label, fixed‐sequence, two‐period study in healthy adult participants.

Garcinoic Acid Is a Natural and Selective Agonist of Pregnane X Receptor

, 2019
Pregnane X receptor (PXR) is a master xenobiotic-sensing transcription factor with a key role in drug metabolism and disposition. Its activity regulates a number of physiological processes in the liver and intestine, and it is now a validated target for ...

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, Volume 20, Issue 6, Page 1494-1512, June 2026.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Crossroads between drug and energy metabolism : role of constitutive androstane receptor and AMP-activated kinase [PDF]

, 2010
Phenobarbital (PB) is a prototype inducer of genes encoding drug metabolizing enzymes including the cytochromes P450 (CYPs). Additionally, phenobarbital was found to repress genes that encode enzymes involved in gluconeogenesis such as ...

Induction of cytochrome P450 2C9 and P‐glycoprotein activity by antiseizure medications: A systematic review and network meta‐analysis

Epileptic Disorders, Volume 28, Issue 3, Page 855-867, June 2026.
Abstract Objectives Antiseizure medications (ASMs) can induce the activity of drug‐metabolizing enzymes and drug transporters, including cytochrome P450 (CYP)2C9 and P‐glycoprotein (P‐gp). Our objective was to comparatively assess the effects of ASMs on exposure to clinical CYP2C9 and P‐gp substrates.

The pregnane X receptor drives sexually dimorphic hepatic changes in lipid and xenobiotic metabolism in response to gut microbiota in mice

Microbiome, 2021
Background The gut microbiota–intestine–liver relationship is emerging as an important factor in multiple hepatic pathologies, but the hepatic sensors and effectors of microbial signals are not well defined.

Bile acid metabolism and sleep: Mechanistic interplay and clinical implications of the gut–liver–brain axis

Sleep Research, Volume 3, Issue 2, Page 170-179, June 2026.
Abstract The bidirectional interplay between sleep and metabolic homeostasis is fundamental to physiological health. While the roles of glucose and lipid metabolism in sleep regulation have been extensively characterized, bile acids (BAs), which are traditionally viewed as digestive surfactants, are emerging as critical metabolic messengers with ...

Synthetic drugs and natural products as modulators of constitutive androstane receptor (CAR) and pregnane X receptor (PXR). Drug Metab [PDF]

, 2006
Constitutive androstane receptor (CAR) and pregnane X receptor (PXR) are members of the nuclear receptor superfamily. These transcription factors are predominantly expressed in the liver, where they are activated by structurally diverse compounds ...
