При изучении патологий часто используют гистологические и молекулярно-генетические методы исследования. Для предотвращения загрязнения элементами крови гистологических препаратов проводят перфузию микроциркуляторного русла раствором гепарина, что ведет к его накоплению в ткани образца. Известно, что гепарин является ингибитором полимеразной цепной реакции (ПЦР) за счет блокирования сайтов связывания ДНК-полимеразы с ДНК-мишенью.</p></sec><sec><title>   Цель</title><p>   Цель. Изучить возможность предотвращения влияния нефракционированного гепарина (НФГ), используемого при перфузии органов, на результат оценки уровня экспрессии генов в образцах легких крыс методом ОТ-ПЦР за счет предварительной обработки гепариназой препаратов РНК.</p></sec><sec><title>   Материалы и методы</title><p>   Материалы и методы. Перфузию сосудистого русла крыс проводили НФГ в концентрациях 50 МЕ/мл (n = 3) и 500 МЕ/мл (n = 3) либо раствором хлорида натрия (n = 3) в качестве контроля. Тотальную РНК выделяли из образцов левого легкого крыс, после чего обрабатывали гепариназой. Оценку уровня относительной экспрессии пяти генов: s18, HPRT, Actinβ, GAPDH, Vim до и после обработки гепариназой препаратов выделенной РНК проводили на основе абсолютного значения порогового цикла (Ct), полученного методом ОТ-ПЦР.</p></sec><sec><title>   Результаты</title><p>   Результаты. Данные показали, что НФГ повышает уровень порогового цикла в ОТ-ПЦР. Обработка образцов гепариназой не оказывает воздействие на количество и качество РНК, при этом статистически значимо снижает уровень порогового цикла по сравнению с необработанными гепариназой образцами.</p></sec><sec><title>   Заключение</title><p>   Заключение. При планировании исследования необходимо учитывать искажения результатов генетического исследования, возникающие из-за перфузии органа раствором гепарина. Использование гепариназы эффективно устраняет гепарин-ассоциированное ингибирование ОТ-ПЦР, не влияя на качество и количество исходной РНК.</p></sec></abstract><trans-abstract xml:lang="en"><p>   Background. Histological and genetic methods are often used in the study of pathologies. To prevent contamination of histological preparations with blood, the microvasculature is perfused with a heparin, which leads to its accumulation in the tissue. Heparin is an inhibitor of the polymerase chain reaction (PCR).   Objective. To study the possibility of preventing the influence of unfractionated heparin (UFH), used in perfusion, on the result of gene expression in rat lung samples using RT-PCR by pretreatment RNA with heparinase.   Design and methods. Perfusion of the rats’ vasculature was performed with UFH at concentrations of 50 IU/mL (n = 3) and 500 IU/mL (n = 3), or with a sodium chloride (n = 3) as a control. RNA was isolated from left lung samples and treated with heparinase. The relative expression of five genes (s18, HPRT, Actinβ, GAPDH, Vim) before and after heparinase treatment of isolated RNA preparations was assessed based on the absolute value of the threshold cycle (Ct) obtained by RT-PCR.   Results. UFH increases the threshold cycle level. Treatment of samples with heparinase does not affect the quantity and quality of RNA, but reduce the Ct compared to samples not treated with heparinase.   Conclusion. While planning a study, it is necessary to consider alterations in the results of genetic research that arise due to organ perfusion with a heparin solution. The use of heparinase effectively eliminates heparin-associated RT-PCR inhibition.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гепарин</kwd><kwd>ОТ-ПЦР</kwd><kwd>перфузия тканей</kwd><kwd>РНК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heparin</kwd><kwd>RNA</kwd><kwd>RT-PCR</kwd><kwd>tissue perfusion</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 23-75-10122, https://rscf.ru/project/23-75-10122</funding-statement><funding-statement xml:lang="en">The research was carried out at the expense of a grant from the Russian Science Foundation No. 23-75-10122, https://rscf.ru/ project/23-75-10122</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">Mullis KB.
