Widespread contamination of aquatic systems with polycyclic aromatic hydrocarbons (PAHs) has led to concern about effects of PAHs on aquatic life. Some PAHs have been shown to cause deformities in early life stages of fish that resemble those elicited by planar halogeuated aromatic hydrocarbons (pHAHs) that are agonists for the aryl hydrocarbon receptor (AHR). Previous studies have suggested that activity of cytochrome P4501A, a member of the AHR gene battery, is important to the t...

Flavonoids as aryl hydrocarbon receptor agonists/antagonists: effects of structure and cell context.(Research)
Environmental Health Perspectives ; Chemoprotective phytochemicals exhibit multiple activities and interact with several cellular receptors, including the aryl hydrocarbon (Ah) receptor (AhR). In this study we investigated the AhR agonist/antagonist activities of the following flavonoids: chrysin, phloretin, kaempferol, galangin,

Induction and regulation of the carcinogen-metabolizing enzyme CYP1A1 by marijuana smoke (delta)(9)-tetrahydrocannabinol
American Journal of Respiratory Cell and Molecular Biology ; Induction of the carcinogen-metabolizing enzyme cytochrome P4501A1 (CYP1A1) is a key step in the development of tobacco-related cancers. To determine if marijuana smoke activates CYP1A1, a murine hepatoma cell line expressing an inducible CYP1A1 gene (Hepa-1) was exposed in vitro to tar extracts

In addition to the natural retinoids such as
Did evolution really anticipate dioxin? (aryl hydrocarbon receptor studied)(Brief Article)
Science News ; Most, if not all, mammalian cells possess a clump of proteins that will bind to dioxin, polychlorinated biphenyls (PCBs), and many other toxic pollutants. Once this pairing occurs, the complex travels as a unit to the cell's nucleus, where it can wreak havoc with DNA's normal, genetically
