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 ...

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 ...

Targeting the pregnane X receptor using microbial metabolite mimicry

EMBO Molecular Medicine, 2020
The human PXR (pregnane X receptor), a master regulator of drug metabolism, has essential roles in intestinal homeostasis and abrogating inflammation. Existing PXR ligands have substantial off‐target toxicity.

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 ...

Lactiplantibacillus plantarum CQPC03 Reduces Carrageenan‐Induced Thrombosis in Mice via Controlling the Flora in the Gut

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Lactiplantibacillus plantarum CQPC03 could reduce carrageenan‐induced thrombosis in mice. ABSTRACT This investigation reports the effects of Lactiplantibacillus plantarum CQPC03 (LP‐CQPC03) on preventing thrombus formation and reducing intestinal oxidative stress and inflammation in a carrageenan‐induced mouse thrombosis model. High‐throughput 16S rRNA

Perturbations métaboliques hépatiques : implication des xénosenseurs CAR (Constitutive Androstane Receptor) et PXR (Pregnane X Receptor) et d'un perturbateur endocrinien, le Bisphénol A

, 2012
L'exposition à des contaminants environnementaux est suspectée de perturber les fonctions endocrino-métaboliques des organismes et contribuer au développement de pathologies métaboliques comme le diabète et la stéatose hépatique non alcoolique.

Non-genomic effects of the Pregnane X Receptor (PXR) and Retinoid X Receptor (RXR) in platelets [PDF]

Background: The pregnane X receptor (PXR) is a nuclear receptor (NR) involved in the detoxification of xenobiotic compounds via upregulation of cytochrome P450 enzyme expression. Recently, the presence of PXR was reported in the human vasculature and its

Liver Fibrosis: Molecular Pathogenesis and Therapeutic Interventions

MedComm, Volume 7, Issue 5, May 2026.
We systematically summarized the etiologies, diagnostic approaches, and pathogenic mechanisms of liver fibrosis. Also, the therapeutic interventions for liver fibrosis were systematically classified into two main categories: etiological treatment and mechanism‐based antifibrotic therapies.

Marine and Semi-Synthetic Hydroxysteroids as New Scaffolds for Pregnane X Receptor Modulation

Marine Drugs, 2014
In recent years many sterols with unusual structures and promising biological profiles have been identified from marine sources. Here we report the isolation of a series of 24-alkylated-hydroxysteroids from the soft coral Sinularia kavarattiensis, acting
