Regulation of CAR and PXR Expression in Health and Disease

Cells, 2020
Pregnane X receptor (PXR, NR1I2) and constitutive androstane receptor (CAR, NR1I3) are members of the nuclear receptor superfamily that mainly act as ligand-activated transcription factors. Their functions have long been associated with the regulation of

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 ...

DNA elements for constitutive androstane receptor- and pregnane X receptor-mediated regulation of bovine CYP3A28 gene.

PLoS ONE, 2019
The regulation of cytochrome P450 3A (CYP3A) enzymes is established in humans, but molecular mechanisms of its basal and xenobiotic-mediated regulation in cattle are still unknown.

The ALS‐associated E425K mutation uncouples DNAJC7 from the Hsp70 chaperone cycle

The FEBS Journal, Volume 293, Issue 12, Page 3485-3501, June 2026.
DNAJC7 is a J‐domain protein that plays a key role in protein quality control by regulating Hsp70 activity and preventing protein aggregation. We find that the ALS‐associated E425K mutation in DNAJC7 disrupts productive interaction and activation of Hsp70, thereby blocking the transfer and refolding of client proteins such as TDP‐43.

Bilirubin as a Modulator of WNK1 Protein Signaling: Implications for Neuroinflammatory Diseases

Advanced Science, Volume 13, Issue 27, 13 May 2026.
ABSTRACT Previously regarded merely as a potentially harmful waste product of heme catabolism, bilirubin has now emerged as a pleiotropic molecule with potent antioxidant, anti‐inflammatory, and hormone‐like properties. Recent findings have revealed protective effects against cardiovascular, metabolic, autoimmune, and neoplastic diseases, as well as ...

Probing the Biological Plausibility of Fluoride as an Endocrine Disruptor

Birth Defects Research, Volume 118, Issue 5, May 2026.
ABSTRACT Background Fluoride has come under recent scrutiny regarding concerns over potential neurodevelopmental and endocrine‐related toxicities, with recent reviews by the National Toxicology Program (NTP) and European Food Safety Authority (EFSA) concluding with moderate or reasonable confidence, respectively, that exposure to drinking water having ...

Dexamethasone‐Mediated Regulation of CYP3A4 and UGTs in Human Hepatoma HuH‐7 Cells

Fundamental &Clinical Pharmacology, Volume 40, Issue 3, May 2026.
ABSTRACT Background The application of human hepatic cell lines to early drug discovery and development instead of human primary hepatocytes (HPHs) has been limited because of the low level of drug‐metabolizing enzymes (DMEs). Objective The study aimed to evaluate the effects of dexamethasone (DEX) treatment on DME expression, activities, and ...

The Decrease in Farnesoid X Receptor, Pregnane X Receptor and Constitutive Androstane Receptor in the Liver after Intestinal Ischemia-Reperfusion

Journal of Pharmacy & Pharmaceutical Sciences, 2012
Purpose. Intestinal ischemia-reperfusion (I/R) damages remote organs, including the liver, and promotes multi-organ failure (MOF). However, the molecular mechanisms underlying acute liver injury after intestinal I/R have not been completely elucidated ...

Activation of PXR, CAR and PPARα by pyrethroid pesticides and the effect of metabolism by rat liver microsomes

Heliyon, 2019
In this study, we used reporter gene assays in COS-1 cells to examine the activation of rat pregnane X receptor (PXR), rat constitutive androstane receptor (CAR) and rat peroxisome-proliferator activated receptor (PPAR)α by pyrethroid pesticides, and to ...
