So in nuclear and mitochondrial DNA, guanine hydroxylation to 8-position gives 8­hydroxy­2'­deoxyguanosine (8­OH­dG) and 8­oxo­7,8­dihydro­2'­deoxyguanosine (8­oxo­dG). These substances are one of the predominant products of free radical­induced oxidative damages. They are usually been applied as biomarkers of oxidative stress and carcinogenesis. The direct oxidation of guanine or incorrect inclusion of 8-oxo-dGTP from the nucleotide pool by polymerases, lead to a lack of specificity of the base pairing in DNA, favoring mutagenesis. Firstly 8-oxo-dG has been described by H. Kasai and S. Nishimura in 1983. Since then, this damage has been widely measured in various tissues and body fluids as blood, urine, brain, liver, and others. Today 8-oxo-dG is already used not only as a marker of oxidative stress, but also as a tool for prognosis of diseases and results of applied therapy. Now many efforts are focused on developing the procedure of measurement of 8-oxo-dG content in tissues and body fluids. In this paper we also discuss the role of the 8-oxo-dG as a biomarker of oxidative stress and a predictor of diseases and results of the applied therapy.</p></abstract><trans-abstract xml:lang="ru"><p>8-Оксо-2’-дезоксигуанозин (8-oxo-dG) является преобладающей формой свободнорадикального повреждения ДНК. C момента его обнаружения в 1983 году, это соединение определяют в различных тканях и жидкостях организма: в крови, моче, мозге, печени и др. В данном обзоре рассматривается роль 8-oxo-dG в качестве биомаркера окислительного стресса, предиктора течения заболевания и успеха применяемой терапии у больных, а также методы, с помощью которых он сегодня детектируется в биологических образцах.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>8-оксо-2'-дезоксигуанозин</kwd><kwd>окислительный стресс</kwd><kwd>биомаркеры окислительного стресса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>: 8-oxo-2’-deoxyguanosine</kwd><kwd>oxidative stress</kwd><kwd>biomarker of oxidative stress.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cadet J., Douki T., Ravanat J.-L.
