GenomicsHigh-resolution genome-wide mapping of AHR and ARNT binding sites by ChIP-Seq
The aryl hydrocarbon receptor (AHR) and AHR nuclear translocator (ARNT) activated complex regulates genes in response to the environmental contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). AHR has also emerged as a potential therapeutic target for the treatment of human diseases and different ...

TranscriptomicsTryptamine Serves As a Proligand of the AhR Transcriptional Pathway, and the Activation Is Dependent of Monoamine Oxidases
In this study we show that physiological concentrations of tryptamine (TA) lead to induction of cytochrome P4501A1 transcription through an AhR-dependent mechanism. In addition, we show that activation of the AhR by TA requires a functional monoamino oxidase system, suggesting that TA acts as an AhR...

MetabolomicsGut microbiota-derived 3-indoleacrylic acid mediates ferulic acid protection against aflatoxin B1 hepatotoxicity via AhR-ferroptosis inhibition

Aflatoxin B1 (AFB1)-induced hepatic inflammation poses severe global health burdens with limited interventions. Here, we demonstrated that ferulic acid (FA), a cereal-derived polyphenol, alleviated AFB1 hepatotoxicity by remodeling gut microbiota and activating microbial tryptopha...

MetabolomicsGut microbiota-derived 3-indoleacrylic acid mediates ferulic acid protection against aflatoxin B1 hepatotoxicity via AhR-ferroptosis inhibition

Given that Aflatoxin B1 exposure drives 5% to 28% of global hepatocellular carcinoma cases, the critical paucity of effective interventions for Aflatoxin B1-induced liver injury represents an urgent need. Here, we discover that a cereal-derived polyph...

MetabolomicsGermacrone Protects Against DSS Induced Colitis Through a Gut Microbiota Derived Indole-3-Carboxylic Acid-AhR-ILC3/IL-22 Axis
Ulcerative colitis (UC) is a chronic recurrent inflammatory bowel disease, which is characterized by intestinal microbiota dysbiosis, intestinal barrier and mucosal immune dysfunction. Given the limited effect of biological agents for UC, there is an urgent need to develop more effective pharmacolog...

TranscriptomicsDifferential gene expression in ahr-1 mutants compared to wild-type C. elegans
The aryl hydrocarbon receptor (AHR) functions in higher organisims in development, metabolism and toxic responses. Its Caenorhabditis elegans (C. elegans) ortholog, AHR-1, facilitates neuronal development, growth and movement. We investigated the effect of AHR mutation on the transcriptional profile...

TranscriptomicsMicro-RNAs levels in wildtype vs. Ahr-null adult mouse liver constitutively and in response to doxin treatment.
Dioxin-like chemicals are well-known for their ability to upregulate expression of numerous genes via the AH receptor (AHR). However, recent transcriptomic analyses in several laboratories indicate that dioxin-like chemicals or AHR genotype itself also can downregulate levels of mRNAs encoded by nu...

TranscriptomicsAhR activation by TCDD in the ET, cortical epithelial cell line
Over activation of the aryl hydrocarbon receptor (AhR) by TCDD results ampng other phenotypes in severe thymic atrophy accompanied by immunosuppression. The link between thymic atrophy, skewed thymocyte differntiation and immunosuppression is still not fully resolved. This study investigates the TCD...

MetabolomicsTryptophan Metabolism and AHR Signaling in the Intraocular Fluid of Uveitis: An Exploratory Study Integrating Metabolomics, Single-Cell Transcriptomics, Molecular Docking, and Mendelian Randomization within a Gut–Eye Axis Framework
Uveitis is a highly heterogeneous intraocular inflammatory disease, and recurrent attacks can lead to irreversible visual impairment. Gut microbiota may contribute to its pathogenesis through metabolic products and immune modulation, but existing evidence is largely derived from cross-sectional asso...

MetabolomicsEngineered Bacillus subtilis WB600/ZD reduces post-weaning diarrhea in piglets by modulating gut microbiota and aryl hydrocarbon receptor (AHR) signaling

Post-weaning diarrhea (PWD) causes significant economic losses to the pig farming industry. Our previous study demonstrated that the engineered Bacillus subtilis WB600/ZD (an engineered Bacillus subtilis strain expressing the antimicrobial defensin peptide from Zophobas atratus), alleviates intes...
