Считается, что основная причина ПЭ - это нарушение этапов формирования плаценты, а регуляции экспрессии генов является значимым механизмом развития плацентарной патологии. Классический подход в транскриптомных исследованиях экспрессии основан на поиске дифференциально-экспрессирующихся генов при заболевании, однако такой подход рассматривает гены изолированно, не учитывая их возможные взаимодействия. Более перспективным подходом является анализ коэкспрессии, который описывает гены, вовлеченные в единые биологические пути патологического процесса, а также позволяет выделять в каждом из кластеров наиболее функционально значимый ген в сети - центральный (hub gene).</p></abstract><trans-abstract xml:lang="en"><p>The problem of prevention and early diagnosis of preeclampsia continues to be one of the leading in obstetrics. It`s a major problem that contributes substantially to maternal and perinatal morbidity and mortality worldwide . Gene expression contributes significantly to the pathogenesis of placental diseases. Traditional methods of studying gene expression are based on the search of differentially expressed genes in a disease, but this approach considers genes in isolation. Coexpression analysis describes the genes involved in the unified biological pathways of the pathological process and also allows you to select in each of the clusters the most functionally significant gene in the network - the hub gene.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коэкспрессия</kwd><kwd>транскриптом</kwd><kwd>плацента</kwd><kwd>преэклампсия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coexpression</kwd><kwd>transcriptome</kwd><kwd>placenta</kwd><kwd>preeclampsia</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">Gene Expression Omnibus.
