The enzyme hemoxygenase-I (НO-1), a molecular marker of OS, is a key participant in the system of protection and adaptation of tumor cells under stress.</p><p><bold>Objective.</bold> To find out whether the sensitivity of human melanoma tumor cells to OS depends on the basal and modulator-induced levels of НO-1 expression</p><p><bold>Material and methods.</bold> Human melanoma cell lines were used in the study. The expression of mRNA НO-1 in cells was studied by real-time RT-PCR, the reactive oxygen species content in cells – by flow cytometry and the cytotoxicity of drugs – by MTT assay.</p><p><bold>Results.</bold> According to our data, human melanoma cells have different basal levels of HO-1 transcription: high (3.0–3.5 o. u.) in lines MelIL, MelP, medium (1.5 o. u.) in lines MeWo, MelZ, MelIbr and low (0.5 o. e.) – MelMe, A375).There is no direct correlation between the level of basal cell expression of HO-1 and their sensitivity to the OS inducer – Н<sub>2</sub>О<sub>2</sub>. The hemin-induced increase in HO-1 expression in cells is accompanied by doubled resistance to Н<sub>2</sub>О<sub>2</sub>. It was found that HO-1 repression in the presence of apigenin was registered in melanoma cells with different basal levels, but sensitization to Н<sub>2</sub>О<sub>2</sub> (2–4 times) was observed only for cells with medium (MeWo) and low (A375) levels of basal HO-1 expression. It was found that the decrease in basal expression of HO-1 induced by apigenin is accompanied by an increase in the reactive oxygen species content in cells.</p><p><bold>Conclusions.</bold> The results of our research allow us to recommend natural flavon apigenin, a modulator of HO-1 expression, for inclusion in the chemotherapy and PDT regimens to increase the effectiveness of human melanoma treatment.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Молекулярная основа механизма действия радио- и фотодинамической терапии, а также ряда противоопухолевых химиопрепаратов – окислительный стресс (ОS). Фермент гемоксигеназа-1 (НО-1), молекулярный маркер ОS – ключевой участник системы защиты и адаптации опухолевых клеток в условиях стресса.</p><p><bold>Цель исследования</bold> – выяснить, зависит ли чувствительность опухолевых клеток меланомы человека к ОS от базального и индуцированного модуляторами уровня экспрессии гена НО-1.</p><p><bold>Материалы и методы</bold>. В работе были использованы опухолевые клетки меланомы человека разных линий. Экспрессию мРНК НО-1 в клетках изучали методом полимеразной цепной реакции с обратной транскрипцией в реальном времени, содержание активных форм кислорода в клетках – методом проточной цитометрии, цитотоксичность препаратов – с применением МТТ-метода.</p><p><bold>Результаты.</bold> По нашим данным, клетки меланомы человека имеют разные по величине базальные уровни транскрипции НО-1: высокий (3,0–3,5 o. е.) у линий MelIL, MelP, средний (1,5 о. е.) у линий MeWo, MelZ, MelIbr и низкий (0,5 о. e.) у MelMе, A375). Установлено, что чувствительность клеток к Н<sub>2</sub>О<sub>2</sub>, индуктору OS, не зависит от величины базальной экспрессии НО-1. Гемининдуцированное увеличение базальной экспрессии НО-1 обнаружено только в клетках меланомы со средним (MeWo) и низким (А375) уровнями этого параметра и сопровождается увеличением их устойчивости к Н<sub>2</sub>О<sub>2</sub> (в 2 раза). Определено, что репрессия НО-1 в присутствии апигенина регистрируется в клетках меланомы с разным базальным уровнем, однако сенситизация к Н<sub>2</sub>О<sub>2</sub> (2–4 раза) наблюдалась только для клеток со средним (MeWo) и низким (А375) уровнями базальной экспрессии НО-1. Выявлено, что снижение базальной экспрессии НО-1, индуцированное апигенином, сопровождается увеличением содержания активных форм кислорода в клетках и вносит вклад в увеличение чувствительности их к Н<sub>2</sub>О<sub>2</sub>.</p><p><bold>Заключение.</bold> Результаты нашего исследования показывают значение природного флавона апигенина в качестве модулятора экспрессии HO-1.</p></trans-abstract><kwd-group xml:lang="en"><kwd>HUMAN MELANOMA CELL LINES</kwd><kwd>HEMOXYGENASE-1</kwd><kwd>HEMIN</kwd><kwd>APIGENIN</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>МЕЛАНОМА ЧЕЛОВЕКА</kwd><kwd>ГЕМОКСИГЕНАЗА-1</kwd><kwd>ГЕМИН</kwd><kwd>АПИГЕНИН</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was performed within the framework of NIOKTR No AAAA-A20-120021490101-1 ‶Development of new integrated approaches to the study of mechanisms of malignant cell transformation, progression and metastasis of tumors .</funding-statement><funding-statement xml:lang="ru">Работа выполнена в рамках НИОКТР № АААА-А20-120021490101-1 «Разработка новых комплексных подходов к изучению механизмов злокачественной трансформации клеток, прогрессии и метастазирования опухолей».</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>MacKie R.M., Hauschild A., Eggermont A.M.
