This could be an explanation for the extreme sensitivity of these cells to UV light. In the present study, we confirm the immediate DNA breakage following UV irradiation also for CS group B (CS-B) fibroblasts by DNA migration in the \u201ccomet assay\u201d and extend these findings to other lesions such as 8-oxodeoxyguanosine (8-oxodG), selectively induced by KBrO&lt;sub&gt;3&lt;\/sub&gt; treatment. In contrast, X-ray exposure does not induce differential DNA breakage. This indicates that additional lesions other than the UV-induced photoproducts (cyclobutane pyrimidine dimers, CPD, and 6-pyrimidine-4-pyrimidone products, 6-4 PP), such as 8-oxodG, specifically induced by KBrO&lt;sub&gt;3&lt;\/sub&gt;, are likely to trigger \u201cuncontrolled\u201d DNA breakage in the undamaged genomic DNA in the CS-B fibroblasts, thus accounting for some of the clinical features of these patients.\u00a0\u00a0\u00a0<\/jats:p>","DOI":"10.1159\/000077485","type":"journal-article","created":{"date-parts":[[2004,5,28]],"date-time":"2004-05-28T08:45:10Z","timestamp":1085733910000},"page":"178-181","source":"Crossref","is-referenced-by-count":6,"title":["Potassium bromate but not X-rays cause unexpectedly elevated levels of DNA breakage similar to those induced by ultraviolet light in Cockayne syndrome (CS-B) fibroblasts"],"prefix":"10.1159","volume":"104","author":[{"given":"P.","family":"Mosesso","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Penna","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Pepe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Lorenti-Garcia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Palitti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2004,6,15]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-1119(00)00172-4"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1093\/emboj\/19.5.1157"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1126\/science.275.5302.990"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/S1568-7864(02)00116-7"}],"container-title":["Cytogenetic and Genome Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/77485","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/77485","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T04:22:01Z","timestamp":1745468521000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000077485"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004]]},"references-count":4,"journal-issue":{"issue":"1-4","published-online":{"date-parts":[[2004,5,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000077485","archive":["Portico"],"relation":{},"ISSN":["1424-8581","1424-859X"],"issn-type":[{"value":"1424-8581","type":"print"},{"value":"1424-859X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004]]}}}
