        <p>Изменение экспрессии генов, участвующих в сверочных точках клеточного цикла и запуске апоптоза оказывает влияние на жизнеспособность эмбриона. Проведено исследование уровней экспрессии генов системы репарации и контроля клеточного цикла: APEX1 (MIM*107748), XPD (MIM*126340), СНЕК2 (MIM*604373), P53 (MIM*191170). Уровень экспрессии исследуемых генов в децидуальной и хорионической ткани при физиологически протекающей беременности и при невынашивании беременности первого триместра был проанализирован с помощью RT-qPCR метода. Уровень экспрессии всех исследованных нами генов в децидуальной ткани несколько выше по сравнению с хорионической как в норме, так и при неразвивающейся беременности (р = 0,01). В результате исследования выявлено повышение уровня экспрессии гена XPD в децидуальной ткани при невынашивании беременности по сравнению с нормально протекающей беременностью (р = 0,003). При невынашивании беременности в клетках децидуальной ткани уровень экспрессии СНЕК2 ниже по сравнению с соответствующими образцами хорионической ткани (р = 0,039).</p>

        <p>The early stages of embryonic development are based on the mechanisms that underlie the functioning of several functional groups of proteins and genes encoding them. However, these mechanisms are not studied sufficiently, which significantly complicates the understanding of the laws of interaction of different cell types, individual body systems and the formation of his reactions. During the first trimester of pregnancy, there is an active cell division and fetal cytotrophoblast. Alterations in the expression of genes, involved in the checkpoints and apoptosis, effect on the embryo viability. In this study, we assessed the distribution of repair (APEX1 (MIM*107748), XPD (MIM*126340) and cell cycle control system СНЕК2 (MIM*604373), P53 (MIM*191170). Estimation of expression level of analyzed genes was performed by RT-qPCR method. In the issue of chorionic tissue analysis decreasing of XPD gene expression level was revealed in comparison to normal pregnancy course (р = 0,003). In miscarriage decidual cells in tissue level expression СНЕК2 lower compared with corresponding samples of chorionic tissue (p = 0,039). Expression level of analyzed genes is lower in the decidua then in the chorion both normal and pathological pregnancy (р = 0,01).</p>
