Операционный материал от 44 пациентов с протоковой аденокарциномой поджелудочной железы подвергался морфологическому анализу с молекулярно-генетическим исследованием. В обнаруженных участках анапластического компонента выявляли суммарную РНК с помощью набора RNeasy Mini Kit (Qiagen, Германия). Для молекулярно-генетического исследования эпителиальномезенхимального перехода (ЭМП) использовали 5 генов-маркеров: ZEB1, ZEB2, CDH1, VIM, SNAIL1 (SLUG). Измерение экспрессии генов проводили в 3 разовом повторении, используя интеркалирующий краситель EvaGreen. На серийных парафиновых срезах с применением технологии tissue microarrays, проводили иммуногистохимическое выявление р63, гладкомышечного актина, общего цитокератина, цитокератина 7, виментина, Е-кадгерина (Ventana).</p></sec><sec><title>Результаты</title><p>Результаты. В результате проведенного исследования в клетках анапластического компонента выявлена положительная реакция с мезенхимальными маркерами (виментин, р63, гладкомышечный актин), в отличие от железистого компонента. При молекулярном исследовании анапластического компонента изменения экспрессии генов характеризовались как ЭМП-положительные.</p></sec><sec><title>Заключение</title><p>Заключение. Гетерогенность протокового рака проявляется в появлении анапластического (саркомоподобного) компонента, в котором прослеживается способность эпителиальных опухолевых клеток приобретать свойство мезенхимальных клеток, не требующих стромы и обладающих агрессивным злокачественным потенциалом, влияющем на выживаемость больных.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the research was to study the expression of marker genes for the epithelial-mesenchymal transition in the ductal adenocarcinoma of the pancreas.</p><sec><title>Material and methods</title><p>Material and methods. Surgical material from 44 patients with ductal adenocarcinoma of the pancreas was subjected to morphological analysis with molecular genetic research. Total RNA was detected in the detected sections of the anaplastic component using the RNeasy Mini Kit (Qiagen, Germany). 5 marker genes were used for molecular genetic studies of the epithelial-mesenchymal transition (EMT): ZEB1, ZEB2, CDH1, VIM, SNAIL1 (SLUG). Gene expression was measured in triplicate using an EvaGreen intercalating dye. On serial paraffin sections using tissue microarrays technology, immunohistochemical detection of p63, smooth muscle actin, total cytokeratin, cytokeratin 7, vimentin, E-cadherin (Ventana) was performed.</p></sec><sec><title>Results</title><p>Results. As a result of the study, a positive reaction with mesenchymal markers (vimentin, p63, smooth muscle actin) was detected in the cells of the anaplastic component, in contrast to the glandular component. In a molecular study of the anaplastic component, changes in gene expression were characterized as EMT-positive.</p></sec><sec><title>Conclusion</title><p>Conclusion. The heterogeneity of ductal cancer is manifested in the appearance of an anaplastic (sarcomalike) component, in which the ability of epithelial tumor cells to acquire the property of mesenchymal cells that do not require stroma and have aggressive malignant potential that affects the survival of patients is traced.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кератин-7</kwd><kwd>виментин</kwd><kwd>эпителиально-мезенхимальный переход</kwd><kwd>кератины</kwd><kwd>актины</kwd><kwd>CDH1 протеин</kwd><kwd>кадгерины</kwd><kwd>протоковая карцинома</kwd><kwd>РНК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>keratin-7</kwd><kwd>vimentin</kwd><kwd>epithelial-mesenchymal transition</kwd><kwd>ceratins</kwd><kwd>actins</kwd><kwd>CDH1 protein</kwd><kwd>cadherins</kwd><kwd>carcinoma ductal</kwd><kwd>RNA</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">Паклина О.В., Сетдикова Г.Р.
