Особый интерес представляет изучение эпигенетических модификаций, в частности, метилирования ДНК у пациентов при сочетанном течении аневризмы восходящей аорты и атеросклероза. В работе был выполнен поиск дифференциально метилированных генов, вовлеченных в развитие изолированной и коморбидной с атеросклерозом патологии аорты в крови, коже и тканях аорты пациентов с несиндромальными формами аневризмы восходящей аорты. Установлены различия уровня метилирования гена некодирующей РНК (нкРНК) NR2F1-AS1 при изолированных и сочетанных формах аневризмы и атеросклероза восходящей аорты: гипометилирование в дилатированной области и атеросклеротической бляшке аорты у пациентов с аневризмой, гиперметилирование в области атеросклеротической бляшки при атеросклерозе аорты без аневризмы. Полученные в данной работе результаты свидетельствуют о разнонаправленном изменении уровня метилирования в области гена нкРНК NR2F1-AS1 при аневризме и атеросклерозе восходящей аорты, что подтверждает важность нкРНК при формировании данных патологий.</p></abstract><trans-abstract xml:lang="en"><p>The contradictory findings regarding the comorbidity of thoracic aortic aneurysm and atherosclerosis underscore the need to identify shared and distinct molecular genetic factors underlying the relationship between these pathologies. Particular interest lies in investigating epigenetic modifications, specifically DNA methylation, in patients with concurrent thoracic aortic aneurysm and atherosclerosis. This study aimed to identify differentially methylated genes involved in both isolated and atherosclerosis-comorbid aortic pathology across aortic tissue, blood, and skin samples from patients with non-syndromic forms of thoracic aortic aneurysm. Differential methylation patterns of the non-coding RNA gene NR2F1-AS1 were identified between isolated and comorbid forms of aortic aneurysm and atherosclerosis: hypomethylation was observed in the dilated aortic region and atherosclerotic plaques of thoracic aortic aneurysm patients, whereas hypermethylation was detected in atherosclerotic plaques from patients with atherosclerosis without aneurysm. The results demonstrate bidirectional alterations in methylation levels within the non-coding RNA gene NR2F1-AS1 in both thoracic aortic aneurysm and aortic atherosclerosis, highlighting the significant role of non-coding RNAs in the pathogenesis of these conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аневризма восходящей аорты</kwd><kwd>атеросклероз</kwd><kwd>метилирование</kwd><kwd>некодирующие РНК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thoracic aortic aneurysm</kwd><kwd>atherosclerosis</kwd><kwd>methylation</kwd><kwd>non-coding RNA</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта Российского научного фонда № 22-25-00701.</funding-statement><funding-statement xml:lang="en">The work is supported by the grant of the Russian Science Foundation No. 22-25-00701.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Huhta A., Paavonen T., Mennander A., et al.
