The use of histone deacetylase inhibitor - valproic acid is a promising approach to increasing the differentiation efficiency of various cell types. In this paper we investigate the ability of mouse submandibular salivary gland cells to differentiate into the hepatic direction and the effect of valproic acid on the efficiency of this differentiation. It was shown that the gene expression levels of hepatocyte markers (Aat, Afp, G6p, Pepck, Tat, Cyp3a13) and liver-enriched transcription factors (Hnf-3α, Hnf-3β, Hnf-4α, Hnf-6) were increased after differentiation in salivary gland cells. Valproic acid increases the specificity of hepatic differentiation, reducing the expression levels of the ductal (Krt19, Hhex1, Cyp7a1) and acinar (Ptf1a) markers. After valproic acid exposure, the efficiency of hepatic differentiation also increases, as evidenced by the increase in the gene expression level of Alb and Tdo, and increase in urea production by differentiated cells. No change was found in DNA methylation of the promoter regions of the genes; however, valproic acid treatment and subsequent hepatic differentiation largely affected the histone H3 methylation of liver-enriched genes. Thus, mouse submandibular salivary gland cells are capable of effective differentiation in the hepatic direction. Valproic acid increases the specificity and efficiency of the hepatic differentiation of these cells.</p></abstract><trans-abstract xml:lang="ru"><p>Изучение фенотипической пластичности и дифференцировочных способностей клеток является важной задачей клеточной биологии. В представленной работе исследована способность клеток поднижнечелюстной слюнной железы мыши к дифференцировке в гепатоцитарном направлении, а также проанализировано влияние вальпроевой кислоты, ингибитора гистон-деацетилаз, на эффективность дифференцировки. Показано, что после дифференцировки в клетках слюнной железы возрастает экспрессия генов гепатоцитарных маркеров (Aat, Afp, G6p, Pepck, Tat, Cyp3a13) и факторов транскрипции (Hnf-3α, Hnf-3β, Hnf-4α, Hnf-6). Вальпроевая кислота увеличивает специфичность гепатоцитарной дифференцировки, снижая экспрессию протоковых (Krt19, Hhex1, Cyp7a1) и ацинарных (Ptf1a) маркеров. После воздействия вальпроевой кислоты усиливается также эффективность гепатоцитарной дифференцировки, о чем говорит повышение уровня Alb и Tdo2 и увеличение секреции мочевины дифференцированными клетками. Изменений в характере метилирования промоторных областей генов не обнаружено, однако обработка вальпроевой кислотой и гепатоцитарная дифференцировка в значительной степени затрагивают метилирование гистона H3, ассоциированного с генами, ключевыми для гепатоцитарной дифференцировки. Таким образом, клетки поднижнечелюстной слюнной железы мыши способны к дифференцировке в гепатоцитарном направлении, а вальпроевая кислота увеличивает специфичность и эффективность их дифференцировки.</p></trans-abstract><kwd-group xml:lang="en"><kwd>gene expression</kwd><kwd>hepatic differentiation</kwd><kwd>submandibular salivary gland cells</kwd><kwd>valproic acid</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вальпроевая кислота</kwd><kwd>гепатоцитарная дифференцировка</kwd><kwd>клетки поднижнечелюстной слюнной железы</kwd><kwd>экспрессия генов</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was carried out with a grant from the Russian Science Foundation (project No. 14-50-00029).</funding-statement><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда (проект № 14-50-00029).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>[1] Snykers S., Henkens T., De Rop E., Vinken M., Fraczek J., De Kock J., De Prins E., Geerts A., Rogiers V., Vanhaecke T. // J.
