Induction of Cetacean Cytochrome P4501A1 by b-Naphthoflavone Exposure of Skin Biopsy Slices
Marine mammals can accumulate environmental contaminants in their blubber at concentrations harmful to laboratory animals. Induction of the cytochrome P450 1A1 (CYP1A1) enzyme is widely used as a biomarker of exposure and molecular effects in animal species, yet the validity of this biomarker has not been established in marine mammals. In vivo studies are generally precluded in these protected ...

متن کاملInduction of cytochrome P4501A1.
Cytochrome P4501A1 is a substrate-inducible microsomal enzyme that oxygenates polycyclic aromatic hydrocarbons, such as the carcinogen benzo(a)pyrene, as the initial step in their metabolic processing to water-soluble derivatives. Enzyme induction reflects increased transcription of the cognate CYP1A1 gene. The environmental toxicant 2,3,7,8-tetrachlorodibenzo-p-dioxin is the most potent known ...
متن کاملEffects of Beta-Naphthoflavone and 3-Methylcholantheren on Biochemical Markers in Sturgeon Fish, Huso huso
Background: Polycyclic aromatic hydrocarbons (PAHs) are a predominant group of contaminants that have been shown to accumulate and persist in marine organisms. We evaluated the dose-dependent induction of the cytochrome P4501A (CYP1A) system in the Sturgeon fish, Huso huso after after exposure to PAHs, beta-naphthoflavone (BNF) and 3- methylcholantheren. Methods: The fish were treated by i.p...
