Aryl hydrocarbon receptor ligand effects in RBL2H3 cells

Aryl Hydrocarbon Receptor and Stem Cells

From the biochemical point of view, the aryl hydrocarbon receptor (AHR) is a highly conserved, developmentally regulated, and ligand-activated member of the bHLH/PAS family of transcription factors. The AHR was originally discovered because of the human and animal toxicity of its most potent and persistent ligand, 2,3,7,8-tetrachlorodibenzo-pdioxin, usually just referred to as “dioxin.” The can...

A ligand for the aryl hydrocarbon receptor isolated from lung.

The aryl hydrocarbon receptor (AHR) is a ligand-inducible transcription factor that is best known because it mediates the actions of polycyclic and halogenated aromatic hydrocarbon environmental toxicants such as 3-methylcholanthrene and 2,3,7,8-tetrachlorodibenzo-p-dioxin. We report here the successful identification of an endogenous ligand for this receptor; approximately 20 microg was isolat...

tert-Butylhydroquinone is a novel aryl hydrocarbon receptor ligand.

In contrast to the beneficial effects of tert-butylhydroquinone (tBHQ) as a food antioxidant, a number of studies have shown that chronic exposure to tBHQ may induce carcinogenicity. Therefore, we examined the ability of tBHQ to induce the cytochrome P450 1a1 (Cyp1a1), an enzyme known to play an important role in the chemical activation of xenobiotics to carcinogenic derivatives. A significant ...

Aryl Hydrocarbon Receptor Activation

Aryl hydrocarbon receptor exogenous ligand 3-methylchoranthrene inhibited endometrial cancer cells proliferation.

OBJECTIVE Endometrial cancer (EC) is the most prevalent gynecologic malignancy among women worldwide. Increasing evidence has disclosed the potential role of aryl hydrocarbon receptor (AhR) in the cancer development; however, little is known about its roles in the EC development. In the present study, we evaluated AhR expression in EC tissues as well as cell lines, and investigated the effects ...
