DNA Damage, Mutagenesis and Cancer.
A large number of chemicals and several physical agents, such as UV light and γ-radiation, have been associated with the etiology of human cancer. Generation of DNA damage (also known as DNA adducts or lesions) induced by these agents is an important first step in the process of carcinogenesis. Evolutionary processes gave rise to DNA repair tools that are efficient in repairing damaged DNA; yet...
متن کاملDNA Damage, Mutagenesis, and DNA Repair
This special issue of the Journal of Nucleic Acids is dedicated to DNA damage and two important biological consequences provoked by such damage: lesion repair and lesion-induced mutagenesis. These phenomena have attracted broad interest among a large community of scientists that cross disciplines frommathematics, physics, chemistry, and biology to clinical scientists. The importance of DNA dama...
متن کاملRole of Nicotinamide in DNA Damage, Mutagenesis, and DNA Repair
Nicotinamide is a water-soluble amide form of niacin (nicotinic acid or vitamin B3). Both niacin and nicotinamide are widely available in plant and animal foods, and niacin can also be endogenously synthesized in the liver from dietary tryptophan. Nicotinamide is also commercially available in vitamin supplements and in a range of cosmetic, hair, and skin preparations. Nicotinamide is the prima...
متن کاملDNA polymerase kappa, implicated in spontaneous and DNA damage-induced mutagenesis, is overexpressed in lung cancer.
DNA polymerase kappa (Pol kappa) is a newly identified low-fidelity polymerase implicated in spontaneous and DNA damage-induced mutagenesis. As an initial study to investigate its possible involvement in tumorigenesis, we compared the expression level of Pol kappa in tumors and adjacent nontumorous tissues by Northern blot, semiquantitative RT-PCR, and Western blot analyses. In this study, pair...
متن کاملNeutrophils and respiratory tract DNA damage and mutagenesis: a review.
Inflammation has been recognized as an important factor in cancer development. For the lung, experimental studies with rats, as well as molecular epidemiological studies in humans, have provided evidence that the influx of neutrophils into the airways may be an important process linking inflammation with carcinogenesis. Currently it is believed that the genotoxic capacity of neutrophils is a cr...
