Вспомогательные репродуктивные технологии (ВРТ) являются перспективными методами лечения бесплодия. Персонализированный подход позволяет повысить их эффективность. Одним из таких подходов является разработка методов оценки качества эмбриона для переноса. Качество эмбриона, во многом определяющее успешность процедуры переноса, в значительной мере зависит от качества гамет, участвовавших в оплодотворении. Поэтому разработка неинвазивных методов оценки качества ооцитов востребована для развития персонализированных ВРТ. Молекулярно-биологическая характеристика клеток кумулюса может быть использована для оценки качества ооцитов и прогнозирования успешности имплантации перенесенного эмбриона. Цель исследования: оценка уровня экспрессии потенциальных генов — маркеров качества ооцита (AREG, STAR, PTGS2, HAS2 и SCD5) в кумулюсных клетках здоровых доноров и пациенток с первичным и вторичным типами бесплодия. Материалы и методы. В исследовании участвовало 9 здоровых доноров и 19 доноров из числа лиц, проходящих лечение бесплодия с применением методов ВРТ. Из клеток кумулюса, полученных при подготовке ооцитов к оплодотворению, выделяли РНК и синтезировали кДНК, которую использовали в качестве матрицы для ПЦР в режиме реального времени с праймерами к указанным выше генам интереса. Результаты. Обнаружены достоверные различия в уровне экспрессии гена AREG между клетками кумулюса ооцитов с успешным (процедура закончилась родами) и неудачным исходами ЭКО. Для генов STAR, HAS2, PTGS2 и SCD5 различия не выявлены. Заключение. Метод определения уровня экспрессии генов-маркеров с помощью ПЦР в режиме реального времени является перспективным для оценки качества ооцитов. Ген AREG является одним из возможных генов-маркеров.</p></abstract><trans-abstract xml:lang="en"><sec><title> </title><p> </p></sec><sec><title>Background</title><p>Background. Assisted reproductive technologies (ART) represent the most promising and successful methods of infertility treatment. A personalized approach may enhance its efficacy. One such approach is the development of reliable methods for assessing the quality and selection of embryos for transfer. The quality of the embryo is largely contingent upon the quality of the gametes involved in fertilization; thus, the development of non-invasive methods to assess oocyte quality represents a crucial step in the advancement of personalized ART. It is proposed that molecular and biological characterization of cumulus cells can be utilized to assess oocyte quality and predict the success of implantation of transferred embryos. The aim of the study was to evaluate the expression levels of potential oocyte quality marker genes (AREG, STAR, PTGS2, HAS2 and SCD5) in cumulus cells from healthy donors and patients with primary and secondary infertility. Materials and Methods. Nine donors and 19 patients were enrolled in the study. RNA was isolated from cumulus cells obtained during oocyte preparation for fertilization, and cDNA was synthesized. The cDNA was used as a matrix for real-time PCR with primers for the above-mentioned genes of interest. Results. Significant difference in AREG gene expression was observed between patients with successful (i.e. ended with birth) outcome and with IVF failure. No difference was found for the STAR, HAS2, PTGS2 and SCD5 genes. Conclusion. The method of assessing the expression level of marker genes in cumulus cells by real-time PCR shows considerable promise for the assessment of oocyte quality. The AREG gene is a potential candidate for use as a marker of oocyte quality.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>амфирегулин</kwd><kwd>ооцит-кумулюсный комплекс</kwd><kwd>созревание ооцита</kwd><kwd>экстракорпоральное оплодотворение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>amphiregulin</kwd><kwd>in vitro fertilization</kwd><kwd>oocyte-cumulus complex</kwd><kwd>oocyte maturation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского научного фонда (грант № 24-24-00533).</funding-statement><funding-statement xml:lang="en">This work was financially supported by the Russian Science Foundation (Grantee № 24-24-00533).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zegers-Hochschild F, Adamson GD, Dyer S, et al.
