Among these factors, non-coding RNAs and microRNAs (miRNAs) have been intensively studied in recent years. MiRNAs play an important role in many processes, particularly in cell reprogramming. In this study, we investigated the reprogramming of rat fibroblasts with a deleted locus encoding a cluster comprising 14 miRNAs (from miR-743a to miR-465). The deletion of this locus was demonstrated to decrease significantly the efficiency of the cell reprogramming. In addition, the cells produced by the reprogramming differed from rat embryonic and induced pluripotent stem cells, which was an indication that reprogramming in these cells had not been completed. We suggest that this miRNA cluster or some of its members are involved in regulating the reprogramming of rat cells to a pluripotent state.</p></abstract><trans-abstract xml:lang="ru"><p>Репрограммирование соматических клеток к плюрипотентному состоянию - сложный, много этапный процесс, в регуляции которого участвует множество факторов, в том числе активно изучаемые в последнее время некодирующие РНК, в частности микроРНК. МикроРНК играют важную роль во многих процессах, включая и репрограммирование клеток. Нами изучена возможность репрограммирования фибробластов крысы с делецией участка ДНК, кодирующего кластер из 14 микроРНК (начиная с miR-743a и до miR-465). Показано, что делеция этого участка значительно снижает эффективность репрограммирования клеток. Клетки, полученные в ходе репрограммирования, отличаются от эмбриональных и индуцированных плюрипотентных стволовых клеток крысы, что свидетельствует о незавершенности процесса репрограммирования. Таким образом, можно предположить, что данный кластер микроРНК либо отдельные его представители участвуют в регуляции процесса репрограммирования клеток крысы к плюрипотентному состоянию.</p></trans-abstract><kwd-group xml:lang="en"><kwd>microRNA</kwd><kwd>pluripotent stem cells</kwd><kwd>reprogramming</kwd><kwd>CRISPR/Cas9</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This study was supported by a grant of the Russian Science Foundation No. 16-14-10084.</funding-statement><funding-statement xml:lang="ru">Работа поддержана грантом РНФ № 16-14-10084.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>[1] Takahashi K., Yamanaka S. // Cell. 2006, V.126, №4, P.663-676</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>[2] Greve T.S., Judson R.L., Blelloch R. // Annu.
