Effects of Gender, age and Ethnicity on Human Cytochrome P450 Activity

The expression of CYP enzymes is influenced by both endogenous and exogenous factors. The aim of this analysis was to evaluate whether the age, gender, or ethnicity of the donor should influence the selection of human liver microsomes for drug metabolism studies, as well as whether cigarette smoking and alcohol consumption are reliable indicators of elevated CYP1A2 and CYP2E1 activity, respectively.
