To comparatively analyze the data of key molecular pharmacological and biochemical parameters in patients to reveal a potential marker for the risk of endometrial glandular dilatation (EGD) during therapy with mifepristone for its use in the individual choice of therapy for a specific female patient. Subjects and methods. The investigation enrolled 50 late reproductive-aged patients with myoma of the uterus, which corresponded to the size of that of 6-12-week pregnancy and the interstitial and interstitial-subserous sites of myomatous nodules. Peripheral blood mononuclear cells served as a material for molecular genetic tests; the expression of the sex steroid receptor genes in the mononuclear cell fraction was studied by RT-PCR. Results. EGD was detected in 11 (22%) of the 50 patients treated with mifepristone. The androgen receptor (AR) gene expression in the patients with EGD was shown to be 4 times lower than that in the patients without endometrial changes. Conclusion. Comparison of the expression of the AR gene and the presence of EGD in mifepristone-treated patients could reveal a negative correlation between these indicators. ROC analysis has shown the value of mRNA of the AR gene, the excess of which suggests that there is a low risk for mifepristone-induced EGD. A potential marker for the risk of EGD during mifepristone therapy has been revealed.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования. Сравнительный анализ данных ключевых молекулярно-фармакологических и биохимических параметров пациенток с выявлением потенциального маркера риска развития железистой дилатации эндометрия на фоне терапии мифепристоном, для использования его в индивидуальном подборе терапии конкретной пациентки. Материал и методы. В обследование были включены 50 пациенток позднего репродуктивного возраста с миомой матки, соответствующей по величине от 6- до 12-недельной беременности с интерстициальной и интерстициально-субсерозной локализацией миоматозных узлов. Материалом для молекулярно-генетических исследований служили мононуклеарные клетки периферической крови, уровень экспрессии генов рецепторов половых стероидов в МНФК изучали при помощи метода RT-PCR. Результаты. Железистая дилатация эндометрия обнаружена у 11 из 50 (22%) пациенток, получавших лечение мифепристоном. Показано, что у пациенток с ЖДЭ экспрессия гена андрогенового рецептора (AR) ниже в 4 раза по сравнению с аналогичным параметром у пациенток без изменений в эндометрии. Заключение. Сравнение уровня экспрессии гена AR и наличия ЖДЭ у пациенток на фоне терапии мифепристоном позволило выявить отрицательную корреляцию между данными параметрами. С помощью ROC-анализа показано значение мРНК гена AR, превышение которого свидетельствует о низкой вероятности развития мифепристон-индуцированной ЖДЭ. Выявлен потенциальный маркер риска развития железистой дилатации эндометрия на фоне терапии мифепристоном.</p></trans-abstract><kwd-group xml:lang="en"><kwd>uterine myoma</kwd><kwd>mifepristone</kwd><kwd>gynestril</kwd><kwd>endometrial glandular dilatation</kwd><kwd>progesterone receptor modulator therapy-associated endometrial changes</kwd><kwd>selective progesterone receptor modulators</kwd><kwd>mononuclear cell fraction</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>миома матки</kwd><kwd>мифепристон</kwd><kwd>гинестрил</kwd><kwd>железистая дилатация эндометрия</kwd><kwd>изменения эндометрия</kwd><kwd>ассоциированные с терапией модуляторами рецепторов прогестерона</kwd><kwd>селективные модуляторы рецепторов прогестерона</kwd><kwd>МНФК</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Rein M.S., Barbieri R.L., Friedman A.J.
