Synthetic epoxy-pregnan steroids: effects on anxiety behavior in rats [PDF]

open access: yes, 2016
Neurosteroids like 3α-OH-5α-pregnan-20-one (allopregnanolone) and 3α-OH-5β-pregnan-20-one (pregnanolone) modulate the γ-aminobutyric acid-A (GABAA) receptor function and produce several effects that can be considered for therapeutical pruposes like ...

Vitamin C Alleviates Oxidative Stress in Silver Carp (Hypophthalmichthys molitrix) Fingerlings Exposed to Toxicity Induced by Temephos and Buprofezin

open access: yesAquaculture Research, Volume 2026, Issue 1, 2026.
Context Organophosphates and chitin synthesis inhibitor pesticides pose a significant indirect threat to fish populations, necessitating effective remedial measures. Objective Supplementation with vitamin C (Vit C) in fish feed as a counteracting strategy to mitigate pesticides effect was explored in silver carp (Hypophthalmichthys molitrix ...

Pregnane X receptor knockout mice display aging-dependent wearing of articular cartilage.

open access: yesPLoS ONE, 2015
Steroid and xenobiotic receptor (SXR) and its murine ortholog, pregnane X receptor (PXR), are nuclear receptors that are expressed at high levels in the liver and the intestine where they function as xenobiotic sensors that induce expression of genes ...

Novel plant inducers of PXR-dependent cytochrome P450 3A4 expression in HepG2 cells

open access: yesSaudi Pharmaceutical Journal, 2018
The cytochrome P450 3A4 (CYP3A4) is the most abundant CYP450 enzyme involved in the metabolism of endogenous products and xenobiotics, including prescription drugs and herbals.

Regulation of cytochrome P450 mRNA expression in primary porcine hepatocytes by selected secondary plant metabolites from chicory (Cichorium intybus L.) [PDF]

open access: yes, 2013
Chicory (Cichorium intybus) has been shown to induce enzymes of pharmacokinetic relevance (cytochrome P450; CYP). The aim of this study was to investigate the effects of selected secondary plant metabolites with a global extract of chicory root, on the ...

FBXO44 Regulates FOXP1 Degradation Through AURKA‐Dependent Phosphorylation to Promote Colorectal Cancer Progression

open access: yesAdvanced Science, Volume 12, Issue 47, December 18, 2025.
FBXO44 promotes colorectal cancer progression by targeting FOXP1 for ubiquitin‐mediated degradation. This study reveals a phosphorylation‐dependent mechanism involving AURKA and highlights the FBXO44/FOXP1/Cyclin E2 axis as a potential therapeutic target in colorectal cancer.

Regulation of xenobiotic and bile acid metabolism by the nuclear pregnane X receptor

open access: yesJournal of Lipid Research, 2002
The nuclear pregnane X receptor (PXR; NR1I2) is an integral component of the body's defense mechanism against chemical insult (chemoprotection). PXR is activated by a diverse array of lipophilic chemicals, including xenobiotics and endogenous substances,

Temporal and spatial expression patterns of pregnane X receptor and vitamin K epoxide reductase genes, two core molecular players on fish vitamin K homeostasis and skeletal development. [PDF]

open access: yes, 2012
Vitamin K (VK) is a liposoluble vitamin known to be essential for bone metabolism by two different pathways: (i) by its role as a coenzyme in the gamma-carboxylation of some skeletal proteins (e.g.

Realising the therapeutic potential of neuroactive steroid modulators of the GABAA receptor [PDF]

open access: yes, 2020
In the 1980s particular endogenous metabolites of progesterone and of deoxycorticosterone were revealed to be potent, efficacious, positive allosteric modulators (PAMs) of the GABAA receptor (GABAAR).
