The cytochrome P450 enzyme system is responsible for the metabolism and clearance of a wide array of drugs, toxins and endogenous substrates. The family is involved in metabolism of 70 – 80% of drugs, nutrients, endogenous substances and environmental toxins. Studies concerning Cytochrome P450 polymorphism, expression and regulation have received very little attention in veterinary species (e.g. cattle, swine, poultry), compared to man and laboratory animals. These species are often exposed to drugs, pesticides or pollutants potentially harmfulenAnimal BiotechnologyAnalysisThesis
