Human cytochromes P450 in health and disease.
There are 18 mammalian cytochrome P450 (CYP) families, which encode 57 genes in the human genome. CYP2, CYP3 and CYP4 families contain far more genes than the other 15 families; these three families are also the ones that are dramatically larger in rodent genomes. Most (if not all) genes in the CYP1, CYP2, CYP3 and CYP4 families encode enzymes involved in eicosanoid metabolism and are inducible...
متن کاملCytochromes P450 in the bioactivation of chemicals.
The initial view that the cytochrome P450 enzyme system functions simply in the deactivation of xenobiotics is anachronistic on the face of mounting evidence that this system can also transform many innocuous chemicals to toxic products. However, not all xenobiotic-metabolising cytochrome P450 subfamilies show the same propensity in the bioactivation of chemicals. For example, the CYP2C, 2B and...
متن کاملThe roles of cytochromes P450 in vascular biology and cardiovascular homeostasis
Cardiovascular disease and atherosclerosis are human health crises that remain the leading cause of death worldwide. The cytochromes P450 (CYPs) are key metabolizing enzymes of both xenobiotics and endobiotics. Many CYP enzymes have been identified in the heart, kidneys, endothelium, and smooth muscle of blood vessels. Furthermore, mounting evidence points to the role of endogenous CYP-dependen...
متن کاملThe Role of Cytochromes P450 in Infection
Cytochromes are expressed in many different tissues of the human body. They are found mostly in intestinal and hepatic tissues. Cytochromes P450 (CYPs) are enzymes that oxidize substances using iron and are able to metabolize a large variety of xenobiotic substances. CYP enzymes are linked to a wide array of reactions including and O-dealkylation, S-oxidation, epoxidation, and hydroxylation. Th...
متن کاملWhichCyp: prediction of cytochromes P450 inhibition
SUMMARY In this work we present WhichCyp, a tool for prediction of which cytochromes P450 isoforms (among 1A2, 2C9, 2C19, 2D6 and 3A4) a given molecule is likely to inhibit. The models are built from experimental high-throughput data using support vector machines and molecular signatures. AVAILABILITY The WhichCyp server is freely available for use on the web at http://drug.ku.dk/whichcyp, wh...
