Potential genoprotective role for UDP-glucuronosyltransferases in chemical carcinogenesis: initiation of micronuclei by benzo(a)pyrene and benzo(e)pyrene in UDP-glucuronosyltransferase-deficient cultured rat skin fibroblasts.

UDP-glucuronosyltransferases (UGTs) are cytoprotective and may also be genoprotective. Since over 10% of the population have hereditary deficiencies in UGTs, this family of enzymes could constitute an important determinant of susceptibility to chemical carcinogenesis, teratogenesis, and neurodegeneration. Fibroblasts contain Phase I and II drug-metabolizing… CONTINUE READING
