Регуляция данного процесса может быть обусловлена изменениями экспрессии представителями семейства костных морфогенетических белков (BMP), однако изменение их экспрессии при развитии EndMT остаётся недостаточно изученной. Целью исследования было изучение динамики экспрессии генов BMP2 и BMP7 при моделировании эндотелиально-мезенхимального перехода в культуре эндотелиальных клеток пупочной вены человека (HUVEC). Исследование выполнено на первичной культуре HUVEC 3 пассажа. EndMT индуцировали воздействием рекомбинантного TGF-β1 (0,5 нг/мл). Функциональные изменения клеток оценивали методом «заживления царапины». Экспрессию генов BMP2, BMP7, α-SMA и TGF-β определяли методом количественной ПЦР в реальном времени. Статистический анализ проводили с использованием непараметрических критериев Манна — Уитни и Краскела — Уоллиса. Было установлено, что добавление TGF-β1 приводило к значительному снижению миграционной активности эндотелиальных клеток. Развитие EndMT сопровождалось постепенным повышением экспрессии BMP2 и α-SMA с выраженным подавлением экспрессии BMP7. Наиболее выраженные молекулярные изменения наблюдались через 48 часов и достигали максимума к 7 суткам. Полученные результаты свидетельствуют о разнонаправленной регуляции BMP2 и BMP7 в процессе EndMT и указывают на участие изменения экспрессии генов BMP в формировании мезенхимального фенотипа клеток.</p></abstract><trans-abstract xml:lang="en"><p>Endothelial-to-mesenchymal transition (EndMT) represents one of the key mechanisms underlying endothelial cell transformation and contributes to the development of pulmonary fibrotic remodeling. The regulation of this process may involve alterations in the expression of bone morphogenetic proteins (BMPs); however, the expression dynamics of BMP family members during EndMT remain insufficiently characterized. The aim of this study was to investigate the temporal changes in BMP2 and BMP7 gene expression during the induction of endothelial-to-mesenchymal transition in human umbilical vein endothelial cells (HUVEC). The study was performed using primary HUVEC cultures at passage 3. EndMT was induced by treatment with recombinant TGF-β1 (0,5 ng/mL). Functional alterations in cell behavior were assessed using the scratch wound healing assay. The expression levels of BMP2, BMP7, α-SMA, and TGF-β genes were determined by quantitative real-time polymerase chain reaction (qRT-PCR). Statistical analysis was performed using the nonparametric Mann–Whitney U test and Kruskal–Wallis test. TGF-β1 stimulation resulted in a significant reduction in endothelial cell migratory activity. The progression of EndMT was accompanied by a gradual increase in BMP2 and α-SMA expression, along with a pronounced suppression of BMP7 expression. The most prominent molecular changes were observed after 48 h of stimulation and reached their maximum intensity by day 7. These findings demonstrate the differential regulation of BMP2 and BMP7 during EndMT and suggest that an imbalance in BMP gene expression contributes to the acquisition of a mesenchymal phenotype by endothelial cells.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эндотелиально-мезенхимальный переход</kwd><kwd>HUVEC</kwd><kwd>TGF-β1</kwd><kwd>BMP2</kwd><kwd>BMP7</kwd><kwd>α-SMA</kwd><kwd>миофибробласты</kwd><kwd>фиброз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endothelial-to-mesenchymal transition</kwd><kwd>HUVEC</kwd><kwd>TGF-β1</kwd><kwd>BMP2</kwd><kwd>BMP7</kwd><kwd>α-SMA</kwd><kwd>myofibroblasts</kwd><kwd>fibrosis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках ГПНИ Экспериментальная медицина и медицинские биотехнологии, подпрограммы» подпрограммы 11.1 «Экспериментальная физиология и биомедицина»: «Изучение роли костных морфогенетических белков в эндотелиально-мезенхимальном переходе при фиброзе легких» № ГР 20251360 от 16.09.2025</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">Interstitial lung diseases / M.
