Abstract:
The cytochrome P450 (CYP) enzymes, involved in the metabolism of therapeutic drugs, are the major determinants of drug half-life. From a drug industry perspective, variability in drug response owing to CYP polymorphisms makes CYP profiling a commercially interesting option for diagnosis, prognosis and predicting response to drug treatment. Recent studies highlighting microRNA-mediated regulation of CYP genes represents a major advance in our understanding of variations in individual drug responses. Herein we review new perspectives on the molecular mechanisms of CYP regulation and genotyping technologies. Together, these developments present novel therapeutic opportunities and help to explain the integrated response of cells to xenobiotic drug metabolism.

Factors Affecting Drug Biotransformation: Biological
Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...
