CYTOCHROME P450 1A1 EXPRESSION IN CETACEAN INTEGUMENT: IMPLICATIONS FOR DETECTING CONTAMINANT EXPOSURE AND EFFECTS

A bstract Contaminant related health risks to marine mammals are typically inferred from the levels of contaminants measured in blubber. Such measurements alone are insufficient to indicate the likelihood of biological effects from contaminant exposure, especially for contaminants that do not bioaccumulate. Cytochrome P450 1A1 (CYP1A1) in mammals is induced by, and involved in, the metabolism of planar halogenated aromatic hydrocarbons and …
