The use of human adenovirus 2 in the study of the xeroderma DNA-repair defect
Abstract:
Ultraviolet-irradiated adenovirus 2 assayed by counting plaques on monolayers of human fibroblast strains is up to 30-fold more sensitive than normal if the strains used as viral hosts are prepared from persons having xeroderma pigmentosum. This plaque assay has been used as an extremely discriminating technique in the study of the xeroderma repair defect. With this assay, every xeroderma fibroblast strain tested has been found to exhibit a DNA-repair defect, including those previously judged by other methods to have normal DNA repair.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
