Identification of functional genetic variants in cyclooxygenase-2 and their association with risk of esophageal cancer.
BACKGROUND & AIMS Overexpression of cyclooxygenase-2 (COX-2) is implicated in many steps of cancer development. Single nucleotide polymorphisms (SNPs) in the COX-2 promoter might contribute toExpand

Human cytochrome P-450PA (P-450IA2), the phenacetin O-deethylase, is primarily responsible for the hepatic 3-demethylation of caffeine and N-oxidation of carcinogenic arylamines.
Aromatic amines are well known as occupational carcinogens and are found in cooked foods, tobacco smoke, synthetic fuels, and agricultural chemicals. For the primary arylamines, metabolic N-oxidationExpand

BACKGROUND The p53 tumor suppressor protein is important in cell-cycle control, apoptosis, and DNA repair. Mutations in p53 have been associated with inherited cancer susceptibility. Because there isExpand

Genotype/phenotype discordance for human arylamine N-acetyltransferase (NAT2) reveals a new slow-acetylator allele common in African-Americans.
Carcinogenic arylamines are acetylated by the hepatic N-acetyltransferase. This enzyme is polymorphic in humans and in some epidemiological studies, the slow-acetylator phenotype has been associatedExpand

Association of genetic variation in tamoxifen-metabolizing enzymes with overall survival and recurrence of disease in breast cancer patients
SummaryTamoxifen has been a mainstay of adjuvant therapy for breast cancer for many years. We sought to determine if genetic variability in the tamoxifen metabolic pathway influenced overall survivalExpand

Susceptibility to esophageal cancer and genetic polymorphisms in glutathione S-transferases T1, P1, and M1 and cytochrome P450 2E1.
Genetic polymorphisms in enzymes involved in carcinogen metabolism have been shown to influence susceptibility to cancer. Cytochrome P450 2E1 (CYP2E1) is primarily responsible for the bioactivationExpand

Distribution and concordance of N-acetyltransferase genotype and phenotype in an American population.
Polymorphic arylamine N-acetyltransferase 2 (NAT2) status varies widely between individuals and ethnic groups and has been associated with susceptibility to several cancers. Few studies have reportedExpand

Determination of CYP1A2 and NAT2 phenotypes in human populations by analysis of caffeine urinary metabolites.
The wide variations in urinary bladder and colo-rectal cancer incidence in humans have been attributed in part to metabolic factors associated with exposure to carcinogenic aromatic and heterocyclicExpand

Genetic polymorphisms in catechol-O-methyltransferase, menopausal status, and breast cancer risk.
Polymorphic catechol-O-methyltransferase (COMT) catalyzes the O-methylation of estrogen catechols. In a case-control study, we evaluated the association of the low-activity allele (COMT(Met)) withExpand
