Поиск потенциально маркерных молекул микроРНК в материале узловых образований поджелудочной железы.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование были включены образцы ткани очаговых образований поджелудочной железы с гистологическим заключением: хронический панкреатит (n = 23), интраэпителиальная неоплазия low grade /PanIN‑1/2 (n = 19) и high grade степени /PanIN‑3 (n = 8), инвазивная протоковая карцинома (n = 26). В рамках работы был проведен широкий профайлинг пулов образцов разных гистологических типов, выбор потенциально маркерных микроРНК, анализ экспрессии выбранных молекул микроРНК во всех образцах, включенных в исследование, поиск статистически значимых различий между группами образцов, апробация нового алгоритма интерпретации полученных результатов путем вычисления соотношений концентраций «реципрокных пар» микроРНК. Метод анализа: обратная транскрипция с последующей количественной ПЦР в режиме реального времени.</p></sec><sec><title>Результаты</title><p>Результаты. Уровень экспрессии молекул miR‑216a и miR‑217 снижается в ряду: PanIN‑1/2 &gt; PanIN‑3 &gt; протоковая карцинома ПЖ. Также в клетках инвазивной протоковой карциномы поджелудочной железы повышена экспрессия miR‑375 и снижена экспрессия miR‑143. Высокая точность дифференциальной диагностики (AUC &gt; 0,95) очагов хронического панкреатита и инвазивной протоковой карциномы ПЖ может быть обеспечена с помощью панели из четырех молекул miR‑216a, miR‑217, miR‑1246 и let‑7a.</p></sec><sec><title>Заключение</title><p>Заключение. Оценка экспрессии молекул микроРНК в материале очаговых образований ПЖ с целью дифференциальной диагностики протоковой карциномы имеет диагностический потенциал, но метод требует валидации с использованием большей коллекции биологических образцов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. Identification of potential miRNA markers in material of focal pancreatic lesions.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Samples of focal pancreatic lesions after histological evaluation were enrolled in the study including chronic pancreatitis (ChP) (n = 23), low-grade pancreatic intraepithelial neoplasia /PanIN‑1/2 (n = 19), high-grade pancreatic intraepithelial neoplasia /PanIN‑3 (n = 8), and invasive pancreatic ductal adenocarcinoma PDAC (n = 26). Workflow of research included the profiling of cancer-associated miRNA in pooled samples, the selection of potential marker miRNAs, the assessment of selected miRNAs expression in total collection of specimens, the identification of differentially expressed miRNAs, and the approbation of new algorithm of data interpretation via ratio of “reciprocal miRNA pair”. Consequent reactions of revers transcription and quantitative teal-time PCR were used.</p></sec><sec><title>Results</title><p>Results. The expression levels of miR‑216a and miR‑217 were decreased in the following order: PanIN‑1/2 &gt; PanIN‑3 &gt; PDAC. Moreover, miR‑375 was up-regulated while miR‑143 was down-regulated in the PDAC. Differential diagnostics of PDAC versus focal chronic pancreatitis might be performed with high accuracy (AUC &gt; 0.95) by assessment panel of four molecules: miR‑216a, miR‑217, miR‑1246 and Let‑7a.</p></sec><sec><title>Conclusion</title><p>Conclusion. The assessment of microRNAs in pancreatic lesions is a promising approach for the differential diagnosis of PDAC, but this technology requires further validation with an increase in the number of samples.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>микроРНК</kwd><kwd>рак поджелудочной железы</kwd><kwd>протоковая неоплазия</kwd><kwd>хронический панкреатит</kwd><kwd>ОТ-ПЦР</kwd><kwd>диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microRNA</kwd><kwd>pancreatic cancer</kwd><kwd>ductal neoplasia</kwd><kwd>chronic pancreatitis</kwd><kwd>RT-PCR</kwd><kwd>diagnostics</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">исследование выполнено в рамках государственного задания Министерства Здравоохранения Российской Федерации «Разработка и клиническая апробация методов диагностики и прогнозирования эффекта терапии онкологических заболеваний на основе анализа микроРНК в биопсийном материале» (№ 121032300206-4) 2021–2023 гг. и в рамках проекта по соглашению № 075-15-2021-709, уникальный (идентификатор проекта RF-2296.61321X0037), финансируемого Министерством науки и высшего образования Российской федерации.</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">Злокачественные новообразования в России в 2020 году (заболеваемость и смертность).
