We used modern transcriptomic technologies to comprehensively characterize the whole genome gene expression profile of human placental syncytiotrophoblast cells (STB) in physiological pregnancy and preeclampsia (PE). As a result of our analysis, we identified 26 differentially expressed genes (DEGs) in the STB cells between healthy and diseased states. The cluster of DEGs contains not only well-known candidate genes identified earlier in many foreign whole genome studies of the placenta (for example, <italic>LEP, INHBA</italic> and <italic>FLT1</italic>), but also new genes (<italic>AC098613.1, AC087857.1, FCRLB, TENM4, PTP4A1P7, LINC01225</italic>, etc.) that can be considered as new biological markers of PE and are of interest for further study. Functional enrichment annotation indicated that most of the DEGs were implicated in the signaling pathways of regulation of hormonal secretion, MAPK cascade, ERK1 and ERK2 cascade, positive regulation of cell adhesion and proliferation of endothelial cells. These processes may be associated with the development of PE at the STB cells level. Additionally, we revealed that alternative splicing of the <italic>FLT1</italic> gene indicate the important role of this RNA processing mechanism in the pathogenetics of PE due to a significant increase in the transcriptional diversity of genes in STB cells. The expression level of the transcript encoding the protein isoform FLT-1 e15a was significantly increased in patients with PE compared to the control group. This study expands understanding of the molecular mechanisms involved in PE and can serve as a basis for developing of preventive, prognostic and therapeutic strategies in the field of personalized obstetrics.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45257552978816">На сегодняшний день транскриптомика – одна из самых быстро развивающихся областей молекулярной биологии, позволяющая получить детальную информацию о функциональной активности генома как в норме, так и при патологии. В представленной работе мы использовали современные транскриптомные технологии для всесторонней характеристики полногеномного профиля экспрессии генов клеток синцитиотрофобласта (СТБ) плаценты человека при физиологической и осложненной преэклампсией (ПЭ) беременности. В результате проведенного нами анализа выявлены 26 генов, экспрессия которых статистически значимо различается в клетках СТБ женщин с ПЭ и физиологическим течением беременности. Кластер дифференциально-экспрессирующихся генов (ДЭГ) содержит не только известные гены-кандидаты, выявленные ранее во многих зарубежных полногеномных исследованиях плаценты (к примеру, <italic>LEP, INHBA</italic> и <italic>FLT1</italic>), но и новые гены (<italic>AC098613.1, AC087857.1, FCRLB, TENM4, PTP4A1P7, LINC01225</italic> и др.), которые могут рассматриваться в качестве новых биологических маркеров ПЭ и представляют интерес для дальнейшего изучения. Результаты функциональной аннотации ДЭГ показывают, что с развитием ПЭ на уровне СТБ могут быть связаны сигнальные пути регуляции гормональной секреции, MAPK-каскада, ERK1 и ERK2 каскада, положительной регуляции клеточной адгезии и пролиферации эндотелиальных клеток. Полученные результаты анализа альтернативного сплайсинга гена <italic>FLT1</italic> свидетельствуют о важной роли в патогенетике ПЭ данного механизма процессинга РНК за счет существенного увеличения транскрипционного разнообразия генов в клетках СТБ. Уровень экспрессии транскрипта, кодирующего белковую изоформу FLT-1 e15a, был значительно повышен у пациенток с ПЭ по сравнению с контрольной группой. Это исследование расширяет представление о задействованных в ПЭ молекулярных механизмах и может служить основой для разработки профилактических, прогностических и терапевтических стратегий в области персонифицированного акушерства.</p></trans-abstract><kwd-group xml:lang="en"><kwd>whole transcriptome sequencing</kwd><kwd>placenta</kwd><kwd>syncytiotrophoblast</kwd><kwd>gene</kwd><kwd>sFlt-1</kwd><kwd>alternative splicing</kwd><kwd>MAPK cascade.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>полнотранскриптомное секвенирование</kwd><kwd>плацента</kwd><kwd>синцитиотрофобласт</kwd><kwd>ген</kwd><kwd>sFlt-1</kwd><kwd>альтернативный сплайсинг</kwd><kwd>MAPK-каскад.</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Gong S., Gaccioli F., Dopierala J. et al.
