</bold>The study of the molecular mechanisms of skin aging is one of the key problems of dermatocosmetology. Inflamaging is a chronic low–level inflammation that occurs with age. This condition is characterized by a change in the expression of proteins involved in the processes of aging and skin regeneration. Hyaluronic acid preparations containing metals have shown their geroprotective effect in the conditions of inflamaging.</p> <p><bold>The aim</bold> of the studyto identify key biomarkers of cell aging (the development of inflamaging), as well as to study the effect of a hyaluronic acid-based drug with the presence of magnesium in chelated form (Magniderm-09) on human skin fibroblasts in an inflamaging model to assess its possible geroprotective effect.</p> <p><bold>Material and methods. </bold>The study was performed on a culture of skin fibroblasts in a model of inflamaging induced by genotoxic stress. To assess the expression of molecular markers, immunohistochemical analysis of levels of Ki-67, collagen I, III and IV, LOX, ubiquitin, CCN1, IL-8, MMP-3, NF-kB, SIRT1, CD44 was performed.</p> <p><bold>Results.</bold> The modeling of inflamaging revealed a decrease in the expression of Ki-67, all types of collagen, LOX, CCN1, SIRT1, CD44, as well as an increase in proinflammatory cytokines – IL-8, NF-kB, MMP-3 and ubiquitin. Administration of the drug "Magniderm-09" returned expression levels to normal values, which indicates its geroprotective effect.</p> <p><bold>Conclusion.</bold> A correlation has been revealed between the chemical composition of a hyaluronic acid-based hydrogel preparation with the presence of magnesium in chelated form and the molecular biological changes accompanying the process of cellular aging.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Исследование молекулярных механизмов старения кожи являются одной из ключевых проблем дерматокосметологии. Инфламэйджинг – хроническое низкоуровневое воспаление, возникающее с возрастом. Данное состояние характеризуется изменением экспрессии белков, участвующих в процессах старения и регенерации кожи. Препараты гиалуроновой кислоты (ГК) с содержанием металловпоказали свое геропротекторное действие в условиях инфламэйджинга.</p> <p><bold>Цель</bold> исследования – выявление ключевых биомаркеров старения клеток (развития инфламэйджинга), а также изучение эффекта воздействия препарата на основе ГК с присутствием магния в хелатной форме (Магнидерм-09) на фибробласты кожи человека в модели инфламэйджинга для оценки его возможного геропротекторного действия.</p> <p><bold>Материал и методы.</bold> Исследование проводили на культуре фибробластов кожи в модели инфламэйджинга, индуцированного генотоксическим стрессом. Для оценки экспрессии молекулярных маркеров проводили иммуногистохимический анализ уровней Ki-67, коллагена I, III и IV, LOX, убиквитинa, CCN1, IL-8, MMP-3, NF-κB, SIRT1, CD44.</p> <p><bold>Результаты.</bold> При моделировании инфламэйджинга выявлено понижение экспрессии Ki-67, всех типов коллагена, LOX, CCN1, SIRT1, CD44, а также повышение провоспалительных цитокинов – IL-8, NF-κB, MMP-3 и убиквитина. Введение препарата «Магнидерм-09» возвращало уровни экспрессии к нормальным значениям, что свидетельствует о его геропротекторном действии.</p> <p><bold>Заключение.</bold> Выявлена корреляция между химическим составом гидрогелевого препарата на основе ГК с присутствием магния в хелатной форме и молекулярно-биологическими изменениями, сопровождающими процесс клеточного старения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>skin aging</kwd><kwd>neuroimmunoendocrinology</kwd><kwd>inflamaging</kwd><kwd>magniderm-09</kwd><kwd>genotoxic stress</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>старение кожи</kwd><kwd>нейроиммуноэндокринология</kwd><kwd>инфламэйджинг</kwd><kwd>магнидерм-09</kwd><kwd>генотоксический стресс</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Franceschi C., Campisi J.
