F M.-A,R Pohjanvirta,J Tuomisto,AB Okey 摘要: The aryl hydrocarbon receptor (AHR) mediates toxicity of 2,3,7,8-tetrachlorodibenzo--dioxin (TCDD) and regulates expression of several genes such as CYP1A1. Little is known about what regulates expression of the AHR itself. We tested the ...
1976). TCDD is a planar hydrophobic rectangular molecule with a Kd of ∼0.5 nmol l−1 for the mouse AHR. A considerable number of structure–activity studies have been performed with dioxin congeners. These studies established the optimal structural requirements to yield a high-affinity binding...
