Squamous cell carcinoma of the tongue is an aggressive form and has a clinically unpredictable prognosis. Currently, there are several histological subtypes of this disease. And the search for new prognostic factors that could reflect the actual state of tumor progression and give an objective prognosis of disease development is an important research area in molecular oncology. Such factors may be certain transcriptomic characteristics of tumors, which determine the features of pathogenesis in each specific case.</p><p><bold>Aim.</bold> To research genes transcriptional activity features in various histological subtypes of tongue squamous cell carcinoma using bioinformatic and molecular approaches.</p><p><bold>Materials and methods.</bold> The stage of screening bioinformatics analysis was performed using an interactive web server for analyzing data on messenger RNA expression of 9736 tumors and 8587 normal samples from the The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) projects using a standard processing pipeline (GEPIA). The main (validation) stage of the study was performed on 300 patients with locally advanced malignant tumors of the tongue. The quantitative real-time polymerase chain reaction method was used to determine the values of the relative expression of genes identified at the stage of bioinformatic analysis.</p><p><bold>Results. </bold>Bioinformatic analysis identified 1488 genes that increase expression and 589 genes that decrease expression in tongue squamous cell carcinoma. Of these 2077 genes, 23 genetic loci were selected that most strongly alter expression in tumor tissue relative to normal tissue of the tongue. Of these, when validated by polymerase chain reaction, only 14 changed their transcriptional profile in tumor tissue relative to normal: MMP1, MMP11, CA9, PTHLH, MMP9, LAMC2, MMP3, ANXA1, MT-ND6, CRNN, MAL, TGM3, IL1RN and CLU. The analysis of polymerase chain reaction data revealed significant heterogeneity in a number of biological samples studied. Cluster analysis made it possible to divide the total sample of 300 patients into 3 groups differing in gene expression: cluster 1 (n = 90), cluster 2 (n = 101) and cluster 3 (n = 109), corresponding to the basaloid, acantholytic and usual histological subtypes. Thus, the study made it possible to identify a number of molecular markers of tongue squamous cell carcinoma (MMP1, MMP11, CA9, PTHLH, MMP9, LAMC2, MMP3, ANXA1, MT-ND6, CRNN, MAL, TGM3, IL1RN and CLU), as well as to reveal the transcriptional features of various histological subtypes of this disease.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>На протяжении последнего десятилетия рак языка сохраняет лидирующие позиции в общей структуре заболеваемости злокачественными опухолями головы и шеи. Плоскоклеточный тип рака языка является агрессивной формой и имеет клинически непредсказуемый прогноз. В настоящее время выделяют несколько гистологических подтипов этой патологии. Поиск новых прогностических факторов, которые могли бы отражать фактическое состояние опухолевой прогрессии и давать объективный прогноз развития болезни, является актуальным направлением исследований в молекулярной онкологии. Такими факторами могут выступать определенные транскриптомные характеристики опухолей, определяющие особенности патогенеза в каждом конкретном случае.</p><p><bold>Цель исследования</bold> – изучение особенностей транскрипционной активности генов в различных гистологических подтипах плоскоклеточного рака языка с применением биоинформационных и молекулярных подходов.</p><p><bold>Материалы и методы.</bold> Этап скринингового биоинформационного анализа выполнен с использованием интерактивного веб-сервера анализа данных по экспрессии матричной РНК 9736 образцов опухолей и 8587 образцов нормальной ткани из проектов Атлас ракового генома (The Cancer Genome Atlas, TCGA) и Genotype-Tissue Expression (GTEx) с применением стандартного конвейера обработки Gene Expression Profiling Interactive Analysis (GEPIA). В ходе основного (валидационного) этапа исследования анализировались данные 300 больных с местно-распространенными злокачественными опухолями языка. Уровень относительной экспрессии генов, выявленных на этапе биоинформационного анализа, определяли методом количественной полимеразной цепной реакции в режиме реального времени.</p><p><bold>Результаты.</bold> В ходе биоинформационного анализа выделены 1488 генов, увеличивающих экспрессию, и 589 генов, уменьшающих экспрессию, при плоскоклеточном раке языка. Из этих 2077 генов были выбраны 23 генетических локуса, наиболее сильно изменяющих экспрессию в опухолевой ткани относительно нормальной ткани языка. Из них при валидации методом полимеразной цепной реакции только 14 изменяли свой транскрипционный профиль в опухолевой ткани относительно нормальной: MMP1, MMP11, CA9, PTHLH, MMP9, LAMC2, MMP3, ANXA1, MT-ND6, CRNN, MAL, TGM3, IL1RN и CLU. При анализе данных с помощью полимеразной цепной реакции выявлена значительная гетерогенность в ряде исследованных биологических образцов. Кластерный анализ позволил разделить общую выборку из 300 пациентов на 3 группы, различающиеся по экспрессии генов: кластер 1 (n = 90), кластер 2 (n = 101) и кластер 3 (n = 109), соответствующие базалоидному, акантолитическому и обычному гистологическим подтипам.</p><p><bold>Заключение.</bold> Таким образом, в ходе исследования выявлен ряд молекулярных маркеров плоскоклеточного рака языка (MMP1, MMP11, CA9, PTHLH, MMP9, LAMC2, MMP3, ANXA1, MT-ND6, CRNN, MAL, TGM3, IL1RN и CLU), а также транскрипционные особенности различных гистологических подтипов этого заболевания.</p></trans-abstract><kwd-group xml:lang="en"><kwd>gene expression</kwd><kwd>tongue squamous cell carcinoma</kwd><kwd>signaling pathways</kwd><kwd>histological subtypes</kwd><kwd>metalloproteinases</kwd><kwd>osteopontin</kwd><kwd>NADH-ubiquinone oxidoreductase</kwd><kwd>keratinocyte differentiation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>экспрессия генов</kwd><kwd>плоскоклеточный рак языка</kwd><kwd>сигнальные пути</kwd><kwd>гистологические подтипы</kwd><kwd>металлопротеиназы</kwd><kwd>остеопонтин</kwd><kwd>NADH-убихиноноксидоредуктаза</kwd><kwd>дифференцировка кератиноцитов</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Льянова А.А., Владимирова Л.Ю., Франциянц Е.М. и др.
