Human and mouse lncRNA (DEANR1 and LL35/Falcor, respectively) located in the genomic environment in close proximity to the Foxa2 transcription factor were discovered earlier. In this work, tissue-specific expression of LL35/Falcor lncRNA has been shown in mouse liver and lungs. The use of antisense oligonucleotides allowed us to achieve LL35/Falcor lncRNA downregulation by 90%. As a result, the level of Foxa2 mRNA and protein dropped, which confirms the involvement of LL35/Falcor lncRNA in the regulation of transcription factor Foxa2. We have shown a decrease in the expression of LL35 lncRNA in liver fibrosis, which correlates with the previously published data for mRNA Foxa2. Thus, lncRNA LL35 regulates Foxa2 expression in the liver not only in normal conditions, but also during development of fibrosis, which allows one to consider lncRNA a biomarker of this pathological process.</p></abstract><trans-abstract xml:lang="ru"><p>Длинные некодирующие РНК (днРНК) играют важную роль в регуляции транскрипции, сплайсинга, трансляции и других процессов в клетке. Ранее у человека и мыши были обнаружены днРНК (DEANR1 и LL35/Falcor соответственно), расположенные в геномном окружении в непосредственной близости от транскрипционного фактора Foxa2. В данной работе показана тканеспецифическая экспрессия днРНК LL35/Falcor в печени и легких мыши. Применение антисмысловых олигонуклеотидов позволило на 90% подавить экспрессию днРНК LL35/Falcor. При этом уменьшилось количество мРНК и белка Foxa2, что подтверждает участие днРНК LL35/Falcor в регуляции фактора транскрипции Foxa2. Нами показано снижение экспрессии днРНК LL35 при фиброзе печени, что коррелирует с выявленным ранее уменьшением количества мРНК фактора Foxa2. Таким образом, днРНК LL35 регулирует экспрессию Foxa2 в печени не только в норме, но и при фиброзе, что позволяет рассматривать эту днРНК в качестве биомаркера этого патологического процесса.</p></trans-abstract><kwd-group xml:lang="en"><kwd>non-coding RNA</kwd><kwd>transcription factor Foxa2</kwd><kwd>regulation</kwd><kwd>liver</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>некодирующие РНК</kwd><kwd>печень</kwd><kwd>транскрипционный фактор Foxa2</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was supported by the Russian Science Foundation (grant No. 17-74-10140).</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке РНФ (грант № 17-74-10140).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
