Существует необходимость поиска новых более информативных показателей для эффективной диагностики ранних стадий РПЖ высокой степени злокачественности. Из области эпигенетики представляет интерес обнаружение гиперметилирования ДНК, которое может служить биомаркером РПЖ, поскольку встречается достаточно часто и способно индуцировать стабильное выключение соответствующего гена, приводя к значительным изменениям в клетке. Целью работы было проведение анализа взаимосвязи метилирования генов APC, GSTP1 и RASSF1A с содержанием ПСА общего и индексом здоровья простаты (PHI) при РПЖ. Материал и методы. В исследование вошли 54 пациента с подозрением на РПЖ, младше 75 лет, с уровнем инициального ПСА общего от 2,5 до 10 нг/мл. Для расчета PHI проводили измерение концентрации ПСА общего, ПСА свободного и предшественника ПСА ([–2]проПСА) в сыворотке крови методом иммунохемилюминесценции. Результаты и их обсуждение. Степень метилирования в образцах плазмы крови и биопсийном материале только гена GSTP1 статистически значимо коррелировала с ПСА-ассоциированными маркерами. Показано повышение величины сопряженности показателей при увеличении степени злокачественности по шкале Глисона. Заключение. В результате выполнения настоящей работы выявлены статистически значимые прямые корреляционные связи изменения паттернов метилирования промоторной области гена GSTP1 и PHI, что позволяет рассматривать их как потенциальных кандидатов для включения в диагностическую панель более эффективного раннего выявления рака предстательной железы.</p></abstract><trans-abstract xml:lang="en"><p>Despite the improvement of prostate cancer (PCa) diagnostic methods and the introduction of prostate-specific antigen (PSA) monitoring, the incidence of advanced PCa in Russia remains high. New more informative variables are needed for the effective diagnosis of early stage and high-grade PCa. In the field of epigenetics of special interest is the detection of DNA hypermethylation, which can serve as a PCa biomarker, since it is common to find and may induce a stable appropriate gene silencing, leading to significant cell changes. Aim of the study was to analyze the relationship between methylation of the APC, GSTP1 and RASSF1A genes and total PSA and prostate health index (PHI) in PCa. Material and methods. The present study included 54 patients with suspicion of PCa, up to 75-years old, who had an initial total PSA level from 2.5 to 10 ng/ml. To calculate PHI value the concentrations of total PSA, free PSA and pre-mature form of PSA ([–2]proPSA) in blood serum were measured by chemiluminescence immunoassay. Results and discussion. The study has revealed the statistically significant correlation between the degree of methylation in blood plasma samples and biopsy material of only the GSTP1 gene and PSA-associated markers. We found an increase of parameters contingency as Gleason score increased. Conclusions. As a result of this work, statistically significant direct correlations were identified between changes in methylation patterns of the promoter region of the GSTP1 gene and PHI, which allows us to consider them as potential candidates for inclusion in a diagnostic panel for more effective early detection of prostate cancer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак предстательной железы</kwd><kwd>шкала Глисона</kwd><kwd>метилирование гена</kwd><kwd>индекс здоровья простаты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>prostate cancer</kwd><kwd>Gleason score</kwd><kwd>gene methylation</kwd><kwd>prostate health index</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Tolkach Y., Kristiansen G.
