[Repaired and unrepaired DNA damage induced by x-irradiation of nonproliferating rat hepatocytes]
Abstract:
An effective system of repair of double-strand DNA breaks was found in the stock culture of rat hepatocytes by the method of elastoviscosimetry. The inhibitors of DNA resynthesis, hydroxyurea and arabinosyl cytosine, which transformed single-strand breaks into double-strand ones were used to estimate the level of spontaneous affection of the hepatocyte genome. With a reference to this level the authors have demonstrated that after a dose of 2 Gy and 6-24-hour repair, the additional number of lesions was registered. These lesions were shown to be incised by nucleases similar to those involved into the conventional repair process.

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...
