Abstract excerpt
Estrogens are critical for breast cancer initiation and development. Sulfotransferase 1A1 (SULT1A1) and UDP-glucuronosyltransferase 1A1 (UGT1A1) conjugate and inactivate both estrogens and their metabolites, thus preventing estrogen-mediated mitosis and mutagenesis. SULT1A1 and UGT1A1 genes are both polymorphic, and different alleles encode functionally different allozymes. We hypothesize that low activity...
