Y-family DNA-polymerases have larger active sites that can accommodate bulky DNA adducts allowing them to bypass these lesions during replication. One member, polymerase eta (pol eta), is specialized for the bypass of UV-induced thymidine-thymidine d

To test the hypothesis that DNA polymerase ζ participates in Ig hypermutation, we generated two mouse models of Pol ζ function: a B cell-specific conditional knockout and a knock-in strain with a Pol ζ mutagenesis-enhancing mutation. Pol ζ-defici

Heterocyclic amine carcinogens such as 2-amino-1-methyl-6-phenylimidazo [4,5-b] pyridine (PhIP) are present in diet and cigarette smoke. Bioactivation in humans includes N-hydroxylation catalyzed by cytochrome P4501A2 possibly followed by O-acetylati

Mutations in DNA are generally considered to have an etiologic role in the development of cancer. If so, it follows that reducing the frequency of such mutations will reduce the incidence of cancer induced by mutagens. Recent advances in elucidating

The discovery of G-rich oligonucleotides (GROs) that have non-antisense antiproliferative activity against a number of cancer cell lines has been recently described. This biological activity of GROs was found to be associated with their ability to fo

Cells that have been irradiated with ultraviolet light (UV) suffer damage to their DNA, primarily in the form of covalent linkage between adjacent pyrimidines. Such photoproducts represent blocks to RNA and DNA polymerases and are potentially mutagen

Xeroderma pigmentosum (XP) is a rare genetic disease characterized by a greatly increased susceptibility to sunlight-induced skin cancer. Cells from the majority of patients are defective in nucleotide excision repair. However, cells from one set of

The cytotoxic and mutagenic effect of 1-nitrosopyrene (1-NOP) and N -acetoxy-2-acetylaminofluorene (N-AcO-AAF) were compared with that of (±)-7β,8α-dihydroxy-9α,10-epoxy-7,8,9,10-tetrahydrobenzo[ a ]pyrene (BPDE) as a function of the initial freq

Xeroderma pigmentosum (XP) variant patients are genetically predisposed to sunlight-induced skin cancer. Fibroblasts from such patients are extremely sensitive to mutations induced by UV radiation, and the spectrum of mutations induced in their hypox
