Examination of the expression of genes responsible for hypoxia-dependent control of transcription, neoangiogenesis, and apoptosis in tumor tissue of the prostate, in patients with localized prostate cancer (РС) with biochemical recurrence (BR) and without recurrences after radical prostatectomy (RPE).</p><p>Materials and methods. The main group included 56 patients with localized PC who had been diagnosed with BR within two years after RP. 60 patients with localized PC who did not relapse had a comparative group. 55 patients in whom operative biopsy specimens of the prostate gland were taken within healthy tissues with the removal of benign prostatic hyperplasia were combined into a control group. Determination of the expression level of the BAX, BCL2, VEGFA and HIF1α genes in tumor tissue was performed by real-time polymerase chain reaction.</p><p>Results. In patients with localized PC after RPE, development of BR is associated with an increase in the expression of BCL2, VEGFA and HIF1α genes and a decrease in the expression of the BAX gene. In patients with localized PC and early recurrence of tumor tissue through a hypoxia-dependent factor that enhances transcritical processes in tumor cells, neoangiogenesis is activated, which is associated with inhibition of apoptosis of tumor cells by enhancing the expression of the antiapoptotic gene BCL2.</p><p>Conclusion. Determination of the expression of BAX, BCL2, VEGFA and HIF1α genes in tumor tissue with localized PC allows further assessment of the risk of disease progression after surgical treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования – изучение экспрессии генов, ответственных за гипоксиязависимый контроль транскрипции, неоангиогенез, а также апоптоз в опухолевой ткани предстательной железы, у больных локализованным раком предстательной железы (РПЖ) с биохимическими рецидивами (БР) и без рецидивов после радикальной простатэктомии (РПЭ).</p><p>Материалы и методы. В основную группу были включены 56 пациентов с локализованным РПЖ, у которых в течение 2 лет после РПЭ выявлен БР. Группу сравнения составили 60 больных локализованным РПЖ, у которых рецидив не наблюдался. В контрольную группу были объединены 55 пациентов, у которых операционные биоптаты предстательной железы взяты в пределах здоровых тканей при удалении доброкачественной гиперплазии предстательной железы. Определение уровня экспрессии генов BAX, BCL2, VEGFA, HIF1α в ткани опухоли проводили методом полимеразной цепной реакции в реальном времени.</p><p>Результаты. У больных локализованным РПЖ после РПЭ развитие БР ассоциировано с повышением экспрессии генов BCL2, VEGFА и HIF1α и снижением экспрессии гена BAX. У больных локализованным РПЖ и с ранним рецидивированием в ткани опухоли, вероятно, через гипоксиязависимый фактор, усиливающий транскрипционные процессы в опухолевых клетках, активируется неоангиогенез, сопряженный с угнетением апоптоза опухолевых клеток за счет усиления экспрессии антиапоптического гена BCL2.</p><p>Заключение. Определение экспрессии генов BAX, BCL2, VEGFA и HIF1α в ткани опухоли при локализованном РПЖ позволяет дополнительно оценить риск прогрессирования заболевания после хирургического лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>prostate cancer</kwd><kwd>biochemical relapse</kwd><kwd>hypoxia-dependent factor</kwd><kwd>angiogenesis</kwd><kwd>apoptosis</kwd><kwd>gene expression</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак предстательной железы</kwd><kwd>биохимический рецидив</kwd><kwd>гипоксиязависимый фактор</kwd><kwd>ангиогенез</kwd><kwd>апоптоз</kwd><kwd>экспрессия генов</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">Sergeeva N.S., Skachkova T.E., Marshutina N.V. et al.
