The model of the placental barrier based on the human choriocarcinoma cell line BeWo b30 allows studying the effect of hypoxia on trophoblast cells. The effect of the oxyquinoline derivative inhibiting HIF-prolyl hydroxylases was studied on this model. Inhibition of these enzymes leads to an increase in the HIF-1α subunit in the cytoplasm, mimicking the cell response to hypoxia. Incubation of the cells with the drug at a concentration of 10 uM for 24 h did not affect the paracellular transport, but reduced the transport of glucose through the cell barrier. The transcriptome analysis after the exposure with oxyquinoline derivative revealed a decreased expression of the KIAA1217 gene and its intronic gene MIR603, which encodes microRNA hsa-miR-603. The expression of the target gene of this miRNA, CCND1 encoding cyclin D1, after oxyquinoline derivative exposition increased significantly, which may indicate a potential microRNA-mRNA regulatory mechanism in the response of trophoblast cells to hypoxia. BeWo b30, placenta, hypoxia, oxyquinoline, barrier, microRNA, cyclin The study was performed with the equipment of the «Postgenomic and Metabolomic Methods of Study in Molecular Biology» Common Use Center (BioClinicum Scientific and Technical Center). The study was supported by the Ministry of Education and Science of the Russian Federation in the framework of the Federal Targeted Program for Research and Development in Priority Areas of Advancement of the Russian Scientific and Technological Complex for 2014-2020 (Project no. RFMEFI58817X0007).

A human choriocarcinoma cell line BeWo b30 imitates cytotrophoblast cells and thus allows to model the placental barrier. Since these cells can form multilayered structures, a method to control the number of cells based on the MTS test has been developed. It was found that during the cell growth on a laminin-521-containing extracellular matrix a significant change in the transepithelial electrical resistance (TEER) and the electrical capacitance of the cell monolayer is observed as compared to the cultivation without the extracellular matrix. The transcriptome analysis of the cells revealed that in the presence of laminin-521, the expression of the ZNF708 gene decreases and that of the SNAI1 and progranuline gene GRN increases as compared to the data obtained without the extracellular matrix. This may indicate that in the first case the cells were prepared to fuse into syncytiotrophoblast. A change in the expression of five microRNA genes and one snoRNA gene was also observed. The above mentioned effects can be associated with the used laminin.

A method to assess the apoptosis level in cell models based on the analysis of the expression of micRNAs located in introns of apoptosis genes has been developed. Bioinformation analysis identified 536 genes associated with apoptosis; 30 of them contained 38 pre-microRNAs encoding 41 mature microRNAs. A significant change in the expression of hsa-miR-1244 and hsa-miR-4479 in response to apoptosis induction in the MCF-7 breast cancer cell line was revealed. A correlation was also found between the expression level of these miRNAs and the size of the primary tumor (process stage) in patients with breast cancer. apoptosis, microRNA, MCF7, breast cancer This work was supported by the Ministry of Education and Science of the Russian Federation (Project no. RFMEFI61618X0092).

The article presents an analysis of the results of monitoring to determine the need to increase the level of competence of specialists of guardianship and guardianship (OOP) (2020), provided by the Department of State Policy in the field of Protection of Children’s Rights of the Ministry of Education of the Russian Federation. In the context of the constant expansion of the powers of PLO specialists, the importance of special professional and methodological training of specialists of guardianship and guardianship authorities in relation to minors in accordance with the requirements of the professional standard and interdisciplinary competencies is evident. 406 specialists of guardianship and guardianship authorities of 85 subjects of the Russian Federation took part in the study. The analysis of 406 questionnaires of PLO specialists with different work experience in the guardianship and guardianship authorities was carried out. The average age of the PLO specialists who took part in the survey is 40 years. The gender composition of respondents is mainly represented by female specialists (92.2% of women with less than 1 year of work experience and 98.3% with more than 5 years of work experience). Representatives of executive authorities in the field of guardianship and guardianship note the need to update the existing professional standard of a specialist of guardianship and guardianship authorities in accordance with changes in state policy in the field of protection of the rights of minors. The most popular forms of receiving methodological assistance are: participation in training seminars, conferences, round tables, webinars; online consultations with experts. PLO specialists prefer to receive methodological support through telephone consultations, through various Internet resources; in the form of methodological recommendations; supervisors, business games, trainings, advanced training courses. The problem area remains the modern content of training programs, a multidisciplinary approach, and the constant expansion of the competencies necessary for the work of specialists. It is shown that for specialists with different work experience, their own principle of building advanced training programs with different volume and content of training for these categories of specialists should be implemented with the obligatory reliance on the case study.
