Pancreatic exocrine microcirculation exhibits sexual dimorphism arising from steroid–genetic interactions. Laser Doppler flowmetry combined with wavelet analysis identifies a male passive coupling phenotype aligned with systemic pressure and a female active vasomotion phenotype driven by ERβ‐mediated, NO‐dependent oscillations.

Origin and diversification of steroids: Co-evolution of enzymes and nuclear receptors [PDF]
Recent sequencing of amphioxus and sea urchin genomes has provided important data for understanding the origins of enzymes that synthesize adrenal and sex steroids and the receptors that mediate physiological response to these vertebrate steroids ...

Pregnane X receptor polymorphisms associated with human diseases
Pregnane X receptor (PXR) belongs to the nuclear hormone receptor superfamily and is mostly expressed in liver and intestine. PXR is activated by a wide range of compounds, including drugs, and regulates the transcription of numerous metabolic enzymes implicated in cellular response to xenobiotics. Genetic variation in the PXR gene may influence a wide

The Structural Basis of Pregnane X Receptor Binding Promiscuity [PDF]
The steroid and xenobiotic-responsive human pregnane X receptor (PXR) binds a broad range of structurally diverse compounds. The structures of the apo and ligand-bound forms of PXR are very similar, in contrast to most promiscuous proteins that generally adapt their shape to different ligands. We investigated the structural origins of PXR's recognition

Microbiome‐based clustering investigated possible glycemic control‐related endotypes in youth with recent‐onset T1D, and found a potential role of Bacteroides and skatole production in glycemic control. This study offers novel perspectives on the influence of intestinal microbes and its metabolites in T1D heterogeneity and lays a foundation for future ...

Background Intestinal dysbiosis is believed to be one of the factors inducing neonatal necrotizing enterocolitis (NEC). Probiotics have been employed to treat NEC in a number of animal experiments and clinical trials, and some significant benefits of ...

Expression, localization and polymorphisms of the nuclear receptor PXR in Barrett's esophagus and esophageal adenocarcinoma [PDF]
Background: The continuous exposure of esophageal epithelium to refluxate may induce ectopic expression of bile-responsive genes and contribute to the development of Barrett's esophagus (BE) and esophageal adenocarcinoma. In normal physiology of the

The Nuclear Pregnane X Receptor Regulates Xenobiotic Detoxification [PDF]
The pregnane X receptor (PXR), which is a member of the nuclear receptor family of ligand-activated transcription factors, is an integral component of the body's defense mechanism against toxic xenobiotics. PXR is activated by a broad spectrum of lipophilic xenobiotics including prescription drugs, herbs, pesticides, endocrine disruptors and other ...

Pregnane X receptor promotes ethanol-induced hepatosteatosis in mice [PDF]
The pregnane X receptor (PXR, NR1I2) is a xenobiotic-sensing nuclear receptor that modulates the metabolic response to drugs and toxic agents. Both PXR activation and deficiency promote hepatic triglyceride accumulation, a hallmark feature of alcoholic liver disease.

ABSTRACT The coevolutionary radiation of 27 species of Tetraopes longhorned beetles and their Asclepias milkweed hosts represents a classic example of adaptive evolution driven by plant chemical defences and herbivore counteradaptations. Investigations to date, however, have focused on a single species, Tetraopes tetrophthalmus, which feeds on the ...
