P450 superfamily: update on new sequences, gene mapping, accession numbers and nomenclature.
TLDR
This revision supersedes the four previous updates in which a nomenclature system, based on divergent evolution of the P450 superfamily has been described and is similar to that proposed in the previous updates. Expand
Role of Aryl Hydrocarbon Receptor-mediated Induction of the CYP1 Enzymes in Environmental Toxicity and Cancer*
TLDR
Differences in AHR affinity between inbred mouse strains reflect variations in CYP1 inducibility and clearly have been shown to be associated with differences in risk of toxicity or cancer caused by PAHs and arylamines. Expand
The UDP glycosyltransferase gene superfamily: recommended nomenclature update based on evolutionary divergence.
TLDR
This review represents an update of the nomenclature system for the UDP glucuronosyltransferase gene superfamily, which is based on divergent evolution and is anticipated that this UGT gene nomenClature system will require updating on a regular basis. Expand
Nomenclature update for the mammalian UDP glycosyltransferase (UGT) gene superfamily.
TLDR
The UGT nomenclature is updated to include new genes identified in the human, mouse and rat genomes and in other mammalian species to prevent confusion when the same gene is given different names. Expand
Clinical importance of the cytochromes P450
The human cytochrome P450 (CYP) superfamily comprises 57 genes. These genes code for enzymes that can have a role in: metabolism of drugs, foreign chemicals, arachidonic acid and eicosanoids;Expand
Comparison of cytochrome P450 (CYP) genes from the mouse and human genomes, including nomenclature recommendations for genes, pseudogenes and alternative-splice variants.
TLDR
The cytochrome P450 (CYP) gene superfamily is summarized and complete identification of all pseudogene sequences is likely to be clinically important, because some of these highly similar exons can interfere with PCR-based genotyping assays. Expand
Role of the aromatic hydrocarbon receptor and [Ah] gene battery in the oxidative stress response, cell cycle control, and apoptosis.
TLDR
The proposed endogenous functions of the AHR and [Ah] enzymes are, of course, in addition to the frequently described functions of "metabolic potentiation" and "detoxification" of various foreign chemicals. Expand
The role of cytochrome P450 enzymes in endogenous signalling pathways and environmental carcinogenesis
TLDR
A two-tiered system to predict an overall inter-individual risk of tumorigenesis based on DNA variants in certain 'early defence' CYP genes, combined with polymorphisms in various downstream target genes is suggested. Expand
P450 genes: structure, evolution, and regulation.
Oral exposure to benzo[a]pyrene in the mouse: detoxication by inducible cytochrome P450 is more important than metabolic activation.
TLDR
The present data indicate that, in the intact animal, inducible CYP1A1 is extremely important in detoxication and protection against oral BaP toxicity. Expand
