Flavonoids as aryl hydrocarbon receptor agonists/antagonists: effects of structure and cell context.

abstract：BACKGROUND:Hexavalent chromium [Cr(VI)] is recognized as a human carcinogen via inhalation. However, the molecular mechanisms by which Cr(VI) causes cancers are not well understood. OBJECTIVES:We evaluated cyclooxygenase-2 (COX-2) expression and the signaling pathway leading to this induction due to Cr(VI) exposure in...
