It has long been appreciated that inflammation and infection reduce drug metabolism and that exposure to drug metabolism-inducing xenobiotics can impair immune function. A new study reveals the mutual repression between the xenobiotic nuclear receptor PXR/SXR and NF-kappaB signaling pathways, providing a molecular mechanism linking xenobiotic metabolism and inflammation (Zhou et al.,).

In women globally, breast cancer ranks as the second most frequent cause of cancer-related deaths, making up about 25% of female cancer cases, which is pretty standard in affluent countries. Breast cancer is divided into subtypes based on aggressive, genetic and stage. The precise cause of the problem is still unknown.

Objective: He Shi Yu Lin Formula (HSYLF) is a clinically proven prescription for treating premature ovarian insufficiency (POI), and has shown a good curative effect. However, its molecular mechanisms are unclear. This study aimed to investigate the molecular mechanisms of HSYLF and clarify how network pharmacology analysis guides the design of animal experiments, including the selection of effective treatment doses and key targets, to ensure the relevance of the experimental results.

Background: Cytochromes P450 (CYPs) are heme-containing oxidoreductase enzymes with mono-oxygenase activity. Human CYPs catalyze the oxidation of a great variety of chemicals, including xenobiotics, steroid hormones, vitamins, bile acids, procarcinogens, and drugs.
Findings: In our review article, we discuss recent data evidencing that the same CYP isoform can be involved in both bioactivation and detoxification reactions and convert the same substrate to different products.

Interactions between plants and herbivores promote evolutionary change. Studying the evolution of herbivore mechanisms aimed to cope with different host plant species is a critical intersection between evolutionary biology and sustainable pest management. Generalist herbivores are of particular interest, as hybridization between genetically distinct populations can increase the standing genetic variation and therefore the adaptive potential of the species.

Alcoholic steatohepatitis (ASH) is a liver disease characterized by steatosis, inflammation, and necrosis of the liver tissue as a result of excessive alcohol consumption. Pregnane X receptor (PXR) is a xenobiotic nuclear receptor best known for its function in the transcriptional regulation of drug metabolism and disposition. Clinical reports suggested that the antibiotic rifampicin, a potent human PXR activator, is a contraindication in alcoholics, but the mechanism was unclear.
