Aryl hydrocarbon receptor and colitis

Seminars in Immunopathology, 2013
The aryl hydrocarbon receptor (AhR), a transcription factor activated by a large variety of natural and synthetic ligands, has recently become the object of great interest among researchers since it represents an important link between environment and immune-mediated pathologies.

Sorafenib is an antagonist of the aryl hydrocarbon receptor

Toxicology, 2022
Sorafenib is an orally administered inhibitor of several tyrosine protein kinases. Treatment with sorafenib induces autophagy, which may suppress the growth of hepatocellular carcinoma (HCC) and other cancers. Aryl hydrocarbon receptor (AhR) is activated by xenbiotics and is involved in detoxification, but also plays other physiological roles.

The aryl hydrocarbon receptor in immunity

Trends in Immunology, 2009
Low-molecular-weight chemicals or xenobiotics might contribute to the increasing prevalence of allergies and autoimmunity. Certain chemicals can alter immune responses via their action on the cytosolic transcription factor aryl hydrocarbon receptor (AhR).

Recombinant aryl hydrocarbon receptors for bioassay of aryl hydrocarbon receptor ligands in transgenic tobacco plants [PDF]

Plant Biotechnology Journal, 2009
SummaryDioxin residues widely contaminate soil and agricultural products at low concentrations and may accumulate in organisms at the top of food chains owing to their physicochemical properties. In this study, we have developed novel, dioxin‐inducible, reporter gene expression systems regulated by recombinant aryl hydrocarbon receptors (AhRs).

The aryl hydrocarbon receptor and light

Biological Chemistry, 2006
The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that has been intensively studied with respect to the toxicity of xenobiotics. However, its function in response to light has never been summarized. Here, we provide an overview of AhR activation by light with a focus on the role of tryptophan in light-induced AhR activation.

Nucleocytoplasmic Shuttling of the Aryl Hydrocarbon Receptor

Journal of Biochemistry, 2000
The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that acts in concert with the AhR nuclear translocator (ARNT), and alters gene expression in response to environmental contaminants such as 2,3,7, 8-tetrachlorodibenzo-p-dioxin (TCDD).

The Aryl Hydrocarbon Receptor Complex

Annual Review of Pharmacology and Toxicology, 1995
The heteromeric unliganded aryl hydrocarbon receptor complex (AHRC) contains the aryl hydrocarbon receptor monomer (AHR). Binding of polycyclic or halogenated aromatic hydrocarbon (PAH and HAH) ligand causes release of AHR, which then associates with the AHR nuclear translocator protein (ARNT) to generate the heterodimeric "transformed" AHRC.
