While XP patients are generally deficient in NER, those with CS are specifically defective in TCR and are characterized by dwarfism and severe developmental abnormalities. The role of TCR in human health will be discussed with specific consideration of t

The indirect effects of metals on DNA may involve inhibition of 8-oxo-dGTPases, a class of enzymes preventing incorpo

It was recently found that mutation in endonuclease V lead to an increase frequency in the expansion of CAG repeats in DNA, a phenoty

Mechanistic studies of carcinogenesis indicate animportant role of this type of damage to DNA. There is al

Results of some markers of exposure and cytogenetic biomarkers (sister chromatid exchange, micronucleus assay and comet assay) has been assessed in the above mentioned occupational groups.

In yeast, a mode of NER which is apparently coupled to transcription requires the activity of Rad26 protein, while transcription-independent NER requires the activity of the Rad7 and Rad 16 proteins. Defects in transcription-dependent NER are associated with the human hereditary disorder Cockayne syndrome (CS).

Prepurification of the targeted base damage prior to derivatization and enzymatic phosphorylation is a requisite to prevent artifactual oxidation to occur in the two former assays. Finally insight is provided on the specificity of repair by DNA-glycosylases using site specific modified oligonucleotides
