Hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) and DL-butyonine sulfoximine (BSO) were added to cells at concentrations of 0.1–100 μM s and 1–500 microns, respectively, at the confluence of 3, 24 and 72 hours.

The concentration of H<sub>2</sub>O<sub>2</sub> 100 μM and BSO 500 μM are toxic to the Caco-2 cell line. The incubation period of 3 hours does not cause the development of OS.</p> <p><bold>Conclusion.</bold> Hydrogen peroxide at concentrations of 5-50 μM, BSO – 10; 50; 100 μM and exposure time of 24 and 72 hours cause the development of compensated oxidative stress (eustress), and H<sub>2</sub>O<sub>2</sub> at concentrations of 100 μM and BSO – 500 μM are toxic to cells of the Caco-2 line.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.</bold> Влияние прооксидантов на клетку может вызывать разные эффекты в зависимости от дозы и длительности воздействия, поэтому для изучения данных процессов необходимы адекватные экспериментальные модели окислительного стресса (ОС) <italic>in vitro</italic>.</p> <p><bold>Цель исследования</bold> – изучить динамику развития ОС при эндогенной и экзогенной его моделях <italic>in vitro.</italic></p> <p><bold>Материал и методы. </bold>Исследование выполнено на линии клеток Сасо-2. Пероксид водорода (Н<sub>2</sub>О<sub>2</sub>) и DL-бутионин-сульфоксимин (БСО) добавляли к клеткам в концентрациях 0,1-100 мкМ и 1-500 мкМ соответственно в течение 3, 24 и 72 ч. По окончании экспозиции определяли процент жизнеспособных клеток (МТТ-тест), уровень активных форм кислорода (MitoTracker Red CM-H2 XRos), количество ядерного фактора эритроидного происхождения (Nrf2) и глутатионпероксидазы (ИФА), концентрацию карбонильных производных белков (фотометрический метод).</p> <p><bold>Результаты.</bold> Показано, что Н<sub>2</sub>О<sub>2</sub> в концентрациях 5, 10, 50 мкМ и БСО – 10, 50, 100 мкМ вызывают повышение уровня карбонильных производных белков, уровня транскрипционого фактора Nrf2 и антиоксидантного фермента – глутатионпероксидазы при сроке воздействия 24 и 72 ч. Концентрации Н<sub>2</sub>О<sub>2 </sub>100 мкМ и БСО 500 мкМ являются токсичными для линии клеток Caco-2. Срок инкубации 3 ч не вызывает развитие ОС.</p> <p><bold>Выводы.</bold> Пероксид водорода в концентрациях 5, 10, 50 мкМ и БСО – 10, 50, 100 мкМ при сроках воздействия 24 и 72 ч вызывают развитие компенсированного окислительного стресса (эустресса), а Н<sub>2</sub>О<sub>2</sub> в концентрации 100 мкМ и БСО – 500 мкМ являются токсичными для клеток линии Сасо-2 (дистресс).</p></trans-abstract><kwd-group xml:lang="en"><kwd>oxidative stress</kwd><kwd>hydrogen peroxide</kwd><kwd>D</kwd><kwd>L-butyonine sulfoximine</kwd><kwd>glutathione peroxidase</kwd><kwd>Nrf-2</kwd><kwd>carbonyl derivatives of proteins</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>окислительный стресс</kwd><kwd>пероксид водорода</kwd><kwd>D</kwd><kwd>L-бутионинсульфоксимин</kwd><kwd>глутатионпероксидаза</kwd><kwd>Nrf-2</kwd><kwd>карбонильные производные белков</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sies H.
