Background: Glucuronidation is a major pathway that enhances the elimination of lipophilic xenobiotics and endobiotics to more more water soluble compounds for excretion (1,2). The UDP-glucuronosyltransferase (UGT) superfamily catalyzes the glucuronidation of the glycosyl group of a nucleotide sugar to a variety of endogenous and exogenous compounds. Over 100 UGT mammalian gene products have been described and have been divided into subfamilies based on sequence identities (3). The UGT1 subfamily consists of a number of gene products resulting from alternative splicing. These UGT products can differ in tissue expression and substrate specificity. Also, marked differences in the individual expression of UGT isoforms can account for differences in drug metabolism.

Background: Cytochrome P450, subfamily 3A, polypeptide 4 (CYP3A4) is a mono-oxygenase enzyme (1) found in the endoplasmic reticulum membrane of liver and prostate microsomes. It is an important enzyme in drug metabolism; it catalyzes phase I oxidation reactions in approximately 50% of drugs in the modern market, as well as steroids, fatty acids, and some carcinogens (2). It is also involved in steroid and cholesterol synthesis (3,4). Expression of CYP3A4 can be induced by glucocorticoids, carcinogens, pesticides, and drugs, which can lead to drug interactions and toxicity (5).

Background: Cytochrome P450 (CYP) is a family of enzymes that contain a heme group (1). These enzymes, when reduced and bound by carbon monoxide, maximally absorb light of 450 nm (1). Type I cytochrome P450s are found in mitochondria and function in the biosynthesis of essential molecules (1). Type II cytochrome P450s are found in endoplasmic reticulum (1). Some type II cytochrome P450s play a role in the biosynthesis of essential molecules whereas others metabolize xenobiotics (1). Research studies show that cytochrome P450s form various heteromeric complexes with other members of the P450 family influencing their catalytic activities (2-4). CYP1A2 is in the endoplasmic reticulum of hepatocytes and responsible for the breakdown of a variety of xenobiotic substances and bioactivation of carcinogens (2, 5). CYP1 enzymes, including CYP1A2, have been implicated in smoking-related osteoporosis (6). A meta-analysis shows that a particular polymorphism in CYP1A2 is potentially linked to increased cancer risk (5).

Background: Cytochrome P450 2D6 (CYP2D6) is a member of the cytochrome P450 superfamily of enzymes. CYP2D6 is located in the endoplasmic reticulum where it oxidizes substrates such as drugs and environmental chemicals (1,2). CYP2D6 metabolizes more than 25% of current commonly used drugs including antidepressants, antipsychotics, analgesics, beta-adrenergic blocking agents, antiarrythmics, and antiemetics. The CYP2D6 gene is highly polymorphic in humans, resulting in phenotypes that vary from poor metabolizer to super metabolizer. A patient's CYP2D6 genotype was shown to be a good predictor of drug response and side effects and is thus used to guide treatments (3-5). Although abundantly expressed in liver, CYP2D6 is also expressed in other organs including brain. In brain, CYP2D6 and other CYP family members are expressed in a cell-specific, region-specific manner (6-8). CYP2D6 functions as a neuroprotective enzyme that increases with age and is induced by nicotine and alcohol (9,10).
