Оценить влияние длительного хранения биобанкированных образцов плазмы крови на профиль циркулирующих малых некодирующих молекул рибонуклеиновой кислоты (микроРНК).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование были включены парные аликвоты плазмы крови 10 пациентов из коллекции биобанка ФГБУ "НМИЦ ТПМ" Минздрава России. Контрольную группу составили образцы микроРНК, выделенные через 1,5 года после получения плазмы и хранившиеся далее в водном растворе 3,5 года. В группе с длительным хранением плазмы микроРНК была выделена из второй аликвоты плазмы через 5 лет. Все образцы хранились при -70 оС. Секвенирование было выполнено для обеих групп одновременно на платформе NextSeq 550 (Illumina, США) по протоколу High Output 1×75 п.н.</p></sec><sec><title>Результаты</title><p>Результаты. Анализ главных компонент на основании данных об уровне экспрессии генов микроРНК человека (версия ENCODE v47) показал разнородность изучаемых групп. В группе с длительным хранением плазмы по сравнению с контролем было выявлено статистически значимое снижение концентрации и размера библиотек, а также более чем двукратное повышение уровня экспрессии для 31 микроРНК.</p></sec><sec><title>Заключение</title><p>Заключение. Циркулирующие микроРНК показали более высокую стабильность при хранении в плазме крови, чем в водном растворе. Полученные результаты указывают на необходимость учета времени хранения выделенной микроРНК наряду с другими преаналитическими факторами для повышения воспроизводимости исследований микроРНК.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To assess the impact of long-term storage of biobanked plasma samples on the profile of circulating small non-coding ribonucleic acids (microRNAs).</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included paired plasma aliquots from 10 patients from the biobank collection of the National Medical Research Center for Therapy and Preventive Medicine. The control group consisted of microRNA samples isolated 1,5 years after plasma collection and then stored in aqueous solution for 3,5 years. In the long-term plasma storage group, microRNA was isolated from a second plasma aliquot after 5 years. All samples were stored at -70 оC. Se­quen­cing was performed for both groups simultaneously on the NextSeq 550 platform (Illumina, USA) using the High Output 1×75 bp protocol.</p></sec><sec><title>Results</title><p>Results. Principal component analysis based on human microRNA gene expression data (ENCODE v47) revealed heterogeneity between the study groups. In the long-term plasma storage group, compared to the control group, a significant decrease in library concentration and size was observed, as well as a more than twofold increase in expression levels for 31 microRNAs.</p></sec><sec><title>Conclusion</title><p>Conclusion. Circulating microRNAs demonstrated higher stability du­ring storage in plasma than in aqueous solution. The obtained results in­di­cate the need to consider the storage time of isolated microRNA, along with other preanalytical factors, to improve the reproducibility of micro­RNA studies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>микроРНК</kwd><kwd>малые некодирующие РНК</kwd><kwd>плазма</kwd><kwd>хранение</kwd><kwd>секвенирование следующего поколения</kwd><kwd>стандартизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microRNA</kwd><kwd>small non-coding RNA</kwd><kwd>plasma</kwd><kwd>storage</kwd><kwd>next-generation sequencing</kwd><kwd>standardization</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Государственное задание "Сво­бод­но циркулирующие микроРНК плазмы крови как диагностические и прогностические биомаркеры ИБС"</funding-statement><funding-statement xml:lang="en">State assignment "Circulating Micro­RNAs in Plasma as Diagnostic and Prognostic Biomarkers of CAD"</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">Matias-­Garcia PR, Wilson R, Mussack V, et al.
