Aim to study the expression and variants of coexpression of transcription factors NeuroD1, Prox1, FoxM1, somatostatin receptors of the 2nd and 5th type, CD38 and CXCR4 receptors in glioblastoma. The methods included an immunohistochemicalstudy with antibodies to Neuro1l, CXCR4, Prox1, FoxM1, CD38, SSTR2, SSTR5and morphometric analysis of glioblastoma fragments from 22 patients (surgical material). Results. A high level of expression (&gt;50% of the cells) of FoxM1 was detected in 85,7% of glioblastomas samples. The average expression level of FoxM1 accouned of 82,8±5,5%. NeuroD1 was expressed in the nuclei of glioblastoma cells in l00% of cases, the average level of its expression was 95,4±0,7%. High levels of CXCR4 expression were detected in l6 tumors (76,2%). The average expression level of CXCR4 was 76,2±6,1%. Proxl was expressed in 57,l% of cases with an average expression level of 58,4±7,0%. All of the above proteins were found in the tumor cells and the walls of its vessels. SSTRs of the 2nd and 5th types were expressed in the cells of the vascular walls in all cases, the expression level was 2,2±1,1 and 6,7±1,2%, respectively. Marked expression of CD38 was observed in only 9,5% of cases. The average level of expression of CD38 - l0,8±3,4%. When analyzing combinations of marker expression, FoxM1+/NeuroD1+/Prox1-/CXCR4+/ CD38- immunophenotype was most often found (in 38,1% of cases). Conclusion. As a result of the study, the expression of CD38 was detected for the first time in glioblastoma cells. High levels of expression of the studied proteins were recorded in the tumor cells and in walls of its vessels. The immunophenotypic heterogeneity of glioblastoma was determined, the most common variant of protein combination in one tumor, FoxM1+/NeuroD1+/Prox1-/CXCR4+/CD38-, was revealed. According to the data obtained, a new personalized approach to treatment is required with the definition of targets for exposure and the corresponding spectrum of drugs in each individual case.</p></abstract><trans-abstract xml:lang="ru"><p>Глиобластома - крайне злокачественная опухоль, для лечения которой в настоящее время относительно эффективен только темозоломид. Цель: изучение экспрессии и вариантов коэкспрессии транскрипционных факторов NeuroD1, Prox1, FoxM1, соматостатиновых рецепторов 2-го и 5-го типа, CD38- и СХСR4-рецепторов в глиобластоме. Методы включали иммуногистохимическое исследование с антителами к NeuroD1, CXCR4, Prox1, FoxM1, CD38, SSTR2, SSTR5 и морфометрический анализ фрагментов глиобластомы от 22 пациентов (операционный материал). Результаты: высокий уровень экспрессии (&gt;50% клеток) FoxM1 был обнаружен в 85,7% глиобластом. Средний уровень экспрести FoxM1 составил 82,8±5,5%. NeuroD1 экспрессировался в ядрах клеток глиобластомы в l00% случаев, средний уровень его экспрести составил 95,4±0,7%. Высокий уровень экспрессии CXCR4 был обнаружен в l6 (76,2%) опухолях. Средний уровень экспрессии CXCR4 составил 76,2±6,l%. Prox1 экспрессировался в 57,1% случаев со средним уровнем экспрессии 58,4+7,0%. Все перечисленные белки были обнаружены в клетках опухоли и стенках ее сосудов. SSTR 2-го и 5-го типов экспрессировались в клетках сосудистых стенок во всех наблюдениях, уровень экспрессии составил соответственно 2,2±1,1 и 6,7±1,2% Заметная экспрессия CD38 наблюдалась всего в 9,5% случаев. Средний уровень экспрессии CD38 составил l0,8±3,4%. При анализе сочетаний экспрессии маркеров наиболее часто (в 38,1% наблюдений) встречался иммунофенотип FoxM1+/NeuroD1+/Prox1-/CXCR4+/CD38-. Заключение: в результате исследования впервые в клетках глиобластомы была обнаружена экспрессия CD38. Высокие уровни экспрессии исследуемых белков зарегистрированы в клетках опухоли и в стенках ее сосудов. Была определена иммунофенотипическая неоднородность глиобластомы, выявлен самый частый вариант сочетания белков в одной опухоли - FoxM1+/ NeuroD1+/Pro1l-/CXCR4+/CD38-. Согласно полученным данным, требуется новый персонифицированный подход к лечению с определением мишеней для воздействия и соответствующего спектра препаратов в каждом индивидуальном случае.</p></trans-abstract><kwd-group xml:lang="en"><kwd>FoxM1</kwd><kwd>CXCR4</kwd><kwd>glioblastoma</kwd><kwd>immunohistochemical study</kwd><kwd>transcription factors</kwd><kwd>FoxM1</kwd><kwd>CXCR4</kwd><kwd>targeted therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>глиобластома</kwd><kwd>иммуногистохимическое исследование</kwd><kwd>факторы транскрипции</kwd><kwd>таргетная терапия</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Thakkar J.P., Dolecek T.A., Horbinski C., Ostrom Q.T., Lightner D.D., Barnholtz-Sloan J.S. and Villano J.L.
