Стандартные схемы лечения не всегда эффективны при этом заболевании, поэтому разработка новых подходов терапии и поиск предиктивных маркеров представляется актуальной научной задачей. Перспективными терапевтическими мишенями при злокачественных новообразованиях являются иммунные контрольные точки (ИКТ). Для понимания патогенеза и оптимизации терапии активно исследуется вклад ИКТ в процессы опухолевой прогрессии. В данном исследовании навыборке пациентов с микросателлитно стабильным фенотипом опухоли РЖ были изучены уровни экспрессии генов ИКТ и их коэкспрессия с генами, вовлеченными в эпителиально-мезенхимальный переход. Проведена оценка ассоциации экспрессии этих генов с клиническими характеристиками РЖ. Показано, что для низкодифференцированных опухолей характерно понижение экспрессии генов CD276 и PVR (p&lt;0,05). Также обнаружено, что развитие метастазов ассоциировано с повышением уровня экспрессии гена TDO2. В случае неметастатического РЖ была выявлена корреляционная связь между уровнями экспрессии генов CD44 и CD276. В группе метастатического РЖ корреляционная связь уровней экспрессии выявлена между генами ADAM17, PVR, CD276 и генами CD44, SNAI1. Полученные данные дополняют представление о молекулярно-генетических механизмах, регулирующих прогрессию опухоли, и могут внести вклад в разработку новых терапевтических подходов, предполагающих совместное ингибирование генов, коэкспрессия которых является особенностью данной нозологии.</p></abstract><trans-abstract xml:lang="en"><p>Gastric cancer (GC) is an aggressive tumor that is one of the leading causes of death from cancer. Treatment regimens are not often effective for this disease, so the development of new approaches to therapy and the search for predictive markers seems to be an urgent scientific task. Immune checkpoints (ICs) are promising therapeutic targets for malignant neoplasms. To understand the pathogenesis and optimize therapy, the role of ICs in tumor progression is being actively studied. In this study, IC gene expression levels and their co-expression with epithelial-mesenchymal transition-related genes were examined in a sample of patients with a microsatellite stable GC tumor phenotype. The association of the expression of these genes with the clinical characteristics of GC was assessed. It was found that the expression of the CD276 and PVR genes was reduced in low-differentiated tumors (p &lt; 0.05). The development of metastases is associated with an increased level of TDO2 gene expression. In non-metastatic GC, a correlation was found between the expression levels of the CD44 and CD276 genes. In metastatic GC, a correlation of expression levels was found between the ADAM17, PVR, CD276 genes and the CD44, SNAI1 genes. The findings add to the understanding of the molecular genetic mechanisms that regulate tumor progression and may contribute to the development of new therapeutic approaches involving mutual inhibition of genes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ген</kwd><kwd>экспрессия</kwd><kwd>рак желудка</kwd><kwd>иммунные контрольные точки</kwd><kwd>эпителиально-мезенхимальный переход</kwd><kwd>микросателлитная нестабильность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gene</kwd><kwd>expression</kwd><kwd>gastric cancer</kwd><kwd>immune checkpoint</kwd><kwd>epithelial-mesenchymal transition</kwd><kwd>microsatellite instability</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Минобрнауки России для ФГБНУ «Медико-генетический научный центр имени академика Н.П.
