Цель исследования – разработать способ оценки результатов иммуногистохимической окраски белка PDCD4. Материал и методы. Материалом для исследования служили 49 образцов ткани аденокарциномы желудка человека и 80 случаев эндоскопического биопсийного исследования слизистой оболочки желудка пациентов с диспептическими жалобами. Морфологические изменения в биоптатах соответствовали хроническому гастриту с разной степенью выраженности воспаления. Для выявления белка PDCD4 иммуногистохимическим методом использовали кроличьи моноклональные анти-PDCD4 антителами (клон EP 102, «abcam», США) и систему детекции («Diagnostic BioSystems», США). Результаты. В рамках представленной работы был разработан метод полуколичественной визуальной оценки синтеза регуляторного белка PDCD4 в гистологических срезах ткани иммуногистохимическим методом с определением его в ядре и цитоплазме. Для этого рассчитывают индекс экспрессии PDCD4 в тканях при суммировании экспрессии в ядрах и в цитоплазме. Ядерная экспрессия представляет собой перемножение частоты окрашивания ядер (0–3 балла) и полуколичественной визуальной оценки интенсивности окрашивания ядер (0–3 балла). Цитоплазматическая экспрессия представляет собой полуколичественную визуальную оценку интенсивности окрашивания цитоплазмы (0–3 балла). Заключение. Предложенный метод позволяет с большей чувствительностью и специфичностью оценить синтез регуляторного белка PDCD4 в тканях, что дает возможность обнаруживать нарушение экспрессии PDCD4 в эпителиальных клетках на ранних этапах опухолевой трансформации клетки. </p></abstract><trans-abstract xml:lang="en"><p>The participation of PDCD4 protein in molecular mechanisms of key importance in carcinogenesis makes the assessment of the level of its synthesis in tissues important for assessing the early diagnosis of malignant tumors. The aim of the presented study was to develop a method for evaluation of the results of immunohistochemical staining of the PDCD4 protein. Material and methods. The material for the study included 49 samples of human gastric adenocarcinoma tissue and 80 cases of endoscopic biopsy examination of the gastric mucosa of patients with dyspeptic complaints. Morphological changes in biopsies corresponded to chronic gastritis with varying degrees of inflammation. Rabbit monoclonal anti-PDCD4 antibodies (clone EP 102, abcam, USA) and a detection system (Diagnostic BioSystems, USA) were used to detect PDCD4 protein by immunohistochemical method. Results. The developed can be used for semi-quantitative visual assessment of synthesis of regulatory protein PDCD4 in histological sections of tissue by immunohistochemical method with detection in nucleus and cytoplasma. That is ensured by calculating an expression index of PDCD4 in tissues when summing up the nuclei expression and cytoplasm expression. Nuclear expression represents a product of staining frequency of nuclei (0–3 points) and semi-quantitative visual assessment of intensity of coloring nuclei (0–3 points). Cytoplasmic expression represents semi-quantitative visual assessment of intensity of cytoplasm (0–3 points). Conclusion. The proposed method makes it possible to evaluate the synthesis of the PDCD4 regulatory protein in tissues with greater sensitivity and specificity, which makes it possible to detect a violation of PDCD4 expression in epithelial cells at the early stages of tumor cell transformation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>белок PDCD4</kwd><kwd>иммуногистохимический метод</kwd><kwd>канцерогенез</kwd></kwd-group><kwd-group xml:lang="en"><kwd>protein PDCD4</kwd><kwd>immunohistochemical method</kwd><kwd>carcinogenesis</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">Мозговой С.И., Кононов А.В., Рубцов В.А., Грищенко Р.К., Парыгина М.Н., Керученко М.А. и др.
