Inhibition of DNA repair is one proposed mechanism for the co-mutagenicity/co-carcinogenicity of arsenic. This review summarizes the current literature on the effects of arsenic compounds on nucleotide excision repair (NER). Several possible mechanisms for the observed NER inhibition have been proposed. Modulation of the expression of NER proteins has been considered to be one possibility of impairing...
Human DNA is exposed to a variety of endogenous and environmental agents that may induce a wide range of damage. The critical role of DNA damage in cancer development makes it essential to develop highly sensitive and specific assays for DNA lesions. We describe here ultrasensitive assays for DNA damage, which incorporate immuno-affinity with capillary electrophoresis (CE) separation and laser induced...
