Показано, что фенофибрат не изменял показатели 5-метилцитозина в ФСК, генистеин и адеметионин их увеличивали на 35% а гидралазин в два раза уменьшал. Выявлена спонтанная продукция IL-6, IL-17, IL- 18 и IL-10 культурах ФСК, добавление ИЛ - 1β значительно усиливало синтез цитокинов. Донаторы метилирования ДНК снижали содержание IL-6 в культурах ФСК. Адеметионин, в максимальной концентрации, в отличие от гидралазина и генистеина снижал продукцию IL-18. Уровень   IL-17 уменьшался при действии модуляторов в малых дозах, а продукция IL-10 практически не менялась. Заключается, что действие модуляторов метилирования на синтез провоспалительных и противовоспалительных цитокинов ФСК связано не только с их влиянием на метилирование ДНК, но и опосредовано другими эпигенетическими механизмами.   Культуры ФСК могут быть использованы как инструмент для доклинической оценки новых модуляторов метилирования ДНК.</p></abstract><trans-abstract xml:lang="en"><p>The effects DNA methylation modulators on  pro- and anti-inflammatory cytokine production by fibroblast-like synoviocytes (FLS) were evaluated using FLS obtained from synovial tissues of 8 patients with active RA and cultivated for 3-7 passages in vitro. </p><p>It was shown that fenofibrate did not change levels of 5-methylcytosine (5-MeC) in FLS,  genistein and ademetionine increased 5-MeC concentrations  by 35%, and hydralazine resulted in twofold decrease of 5-MeC levels.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фибробластоподобные синовиальные клетки</kwd><kwd>ревматоидный артрит</kwd><kwd>метилирование ДНК</kwd><kwd>цитокины</kwd><kwd>генистеин</kwd><kwd>гидралазин</kwd><kwd>адеметионин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fibroblast-like synovial cells</kwd><kwd>rheumatoid arthritis</kwd><kwd>DNA methylation</kwd><kwd>cytokines</kwd><kwd>genistein</kwd><kwd>hydralazine</kwd><kwd>ademethionine</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Шнайдер М.А., Ширинский В.С., Ширинский И.В.
