Nowadays, hematology is a dynamically developing science due to the in-depth study of the molecular mechanisms of a particular disease. A better understanding of oncohematological diseases biology makes it possible to synthesize new targeted drugs, which have a favorable therapeutic effect. In particular, in multiple myeloma, after the introduction of proteasome inhibitors and immunomodulatory drugs into clinical practice, an improvement in overall survival was observed. However, characteristics of the mechanisms of transformation normal plasma cells into malignant ones are still difficult; therefore, the study of the pathobiological basis of multiple myeloma is currently an urgent task.<bold>The objective</bold>: to evaluate the possible influence of <italic>MAGE-C1</italic> gene expression and the presence of mage-c1 protein in patients with newly diagnosed multiple myeloma on the anti-tumor response after bortezomib-containing therapy.<bold>Materials and methods</bold>. A prospective study included 33 multiple myeloma patients. The diagnosis was established according to International Myeloma Working Group criteria (IMWG, 2014). In 32 patients the induction therapy included bortezomib-containing courses, in one patient lenalidomide was included in the first-line regimens. The <italic>MAGE-C1</italic> gene expression by real-time polymerase chain reaction and mage-c1 protein by immunohistochemistry in plasma cells bone marrow, were determined for all patients at the debut of multiple myeloma. As a control group was examined the bone marrow material of healthy donors.<bold>Results</bold>. When assessment the statistical relationship between the expression of <italic>MAGE-C1</italic> gene and mage-c1 protein, it was found that there was no high expression of mage-c1 protein at low values of <italic>MAGE-C1</italic> gene expression. At the same time, high expression of the gene was always associated with protein expression above normal values. The analysis aimed at finding the relationship between <italic>MAGE-C1</italic> gene and mage-c1 protein detection and the degree of antitumor response after 6 courses of induction therapy showed that high expression of the studied parameters was associated with a worse response to bortezomib-containing treatment.<bold>Conclusion</bold>. We confirmed that the results of the two methods were comparable. Single factor analysis showed that patients with decreased <italic>MAGE-C1</italic> gene and mage-c1 protein expression levels achieved a significantly higher antitumor response to bortezomib-containing regimens, while high expression was accompanied by refractoriness to bortezomib.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. В настоящее время гематология является динамично развивающейся наукой ввиду углубленного изучения молекулярных механизмов той или иной болезни. Благодаря лучшему пониманию биологии онкогематологических заболеваний удается синтезировать новые препараты с таргетным механизмом действия, что благоприятно сказывается на лечении пациентов. В частности, при множественной миеломе после введения в клиническую практику ингибиторов протеасом, иммуномодулирующих препаратов отмечено улучшение показателей общей выживаемости. Однако характеристика механизмов, ответственных за трансформацию нормальных плазматических клеток в злокачественные, все также затруднена, в связи с чем изучение патобиологических основ множественной миеломы на сегодняшний день является актуальной задачей.<bold>Цель исследования</bold> – оценить возможное влияние экспрессии гена <italic>MAGE-C1</italic> и наличия белка mage-c1 у больных с впервые выявленной множественной миеломой на противоопухолевый ответ бортезомибсодержащей терапии.<bold>Материалы и методы</bold>. В проспективное исследование были включены 33 больных множественной миеломой. Диагноз устанавливали в соответствии с критериями Международной рабочей группы по изучению ММ (IMWG, 2014). У 32 больных индукционный этап терапии состоял из бортезомибсодержащих курсов, 1 больной в схемы 1-й линии был включен леналидомид. Всем больным в дебюте заболевания определяли экспрессию гена <italic>MAGE-C1</italic> методом полимеразной цепной реакции в реальном времени в плазматических клетках пунктата костного мозга и белка mage-c1, определенного иммуногистохимическим методом в трепанобиоптате костного мозга. В качестве контроля исследовали материал костного мозга здоровых доноров.<bold>Результаты</bold>. При оценке статистической взаимосвязи экспрессии гена <italic>MAGE-C1</italic> и белка mage-c1 выявлено, что при низких значениях экспрессии гена <italic>MAGE-C1</italic> не наблюдалось высокой экспрессии белка mage-c1. При этом высокая экспрессия исследуемого гена всегда ассоциировалась с экспрессией белка выше нормальных значений. Анализ, направленный на поиск взаимосвязи между детекцией гена <italic>MAGE-C1</italic> и белка mage-c1 и степенью противоопухолевого ответа после 6 курсов индукционной терапии показал, что наличие высокой экспрессии изучаемых параметров ассоциировалось с худшим ответом на бортезомибсодержащее лечение.<bold>Заключение</bold>. В рамках проведенного анализа удалось подтвердить, что результаты 2 методов сопоставимы. Однофакторный анализ продемонстрировал, что у больных со сниженными показателями экспрессии гена <italic>MAGE-C1</italic> и белка mage-c1 достижение противоопухолевого ответа на бортезомибсодержащие схемы достоверно выше, в то время как высокая экспрессия сопровождается рефрактерностью к бортезомибу.</p></trans-abstract><kwd-group xml:lang="en"><kwd>multiple myeloma</kwd><kwd><italic>MAGE-C1</italic> gene</kwd><kwd>mage-c1 protein</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>множественная миелома</kwd><kwd>ген <italic>MAGE-C1</italic></kwd><kwd>белок mage-c1</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">1.
