Были обследованы шахтеры угольных шахт Кузбасса (n=507), сотрудники угольных ТЭЦ (n=455) и жители той же местности, не занятые в промышленном производстве (n=798). Оценивали частоту структурных хромосомных аберраций (ХА), проводили микроядерный (МЯ) тест на лимфоцитах крови с цитохалазиновым блоком, изучали частоту гиперметилирования промоторов ключевых генов репарации (XRCC1, XRCC2, XRCC3, XRCC4, ERCC2, ERCC5) с использованием метил-специфической полимеразной цепной реакции. Установлено, что у всех угольщиков повышены частота цитогенетических маркеров повреждений ДНК (ХА, МЯ, мостов, протрузий) и частота встречаемости гиперметилированного и метилированного статусов промоторов изученных генов.</p></abstract><trans-abstract xml:lang="en"><p>It is known that increased concentration of coal dust in the air of the working area of enterprises leads not only to the development of inflammatory diseases of the respiratory system, but also to increased genomic instability in the cells of the immune system, which can have extremely unfavorable consequences. Miners of coal mines of Kuzbass (n = 507), employees of coal thermal power plants (n = 455) and residents of the same area not engaged in industrial production (n = 798) were examined. The frequency of structural chromosomal aberrations (CA) was assessed, a micronucleus (MN) test was performed on blood lymphocytes with a cytochalasin block, the frequency of hypermethylation of promoters of key repair genes (XRCC1, XRCC2, XRCC3, XRCC4, ERCC2, ERCC5) was studied using methyl-specific polymerase chain reaction. It was found that all workers had an increased frequency of CA, MN, bridges, protrusions. An increase in the frequency of occurrence of hypermethylated and methylated statuses of promoters of the studied genes was noted.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>угольные предприятия</kwd><kwd>генотоксические эффекты</kwd><kwd>микроядра</kwd><kwd>хромосомные аберрации</kwd><kwd>метилирование ДНК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coal enterprises</kwd><kwd>genotoxic effects</kwd><kwd>micronuclei</kwd><kwd>chromosomal aberrations</kwd><kwd>DNA methylation</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">Hossain M.N., Paul S.K., Hasan M.M.
