Медь играет важную роль в метаболизме мозга, однако частицы меди нанометрового диапазона могут проявлять нейротоксические свойства и вызывать нарушения работы клеток мозга. </p></sec><sec><title>Материал и методы</title><p>Материал и методы. В течение 6 нед 3 раза в неделю внутрибрюшинно животным вводили суспензию НЧ оксида меди.

Определено статистически достоверное снижение уровня экспрессии генов, кодирующих белки рецептора NMDA, при воздействии наночастиц CuO 0,5 мг/мл (ΔCt(GRIN1) = 0,813; ΔCt(GRIN2A) = 3,477; ΔCt(GRIN2B) = 1,37) в сравнении с контрольной группой (ΔCt(GRIN1) = 6,301; ΔCt(GRIN2A) = 7,823; ΔCt(GRIN2B) = 4,747). </p></sec><sec><title>Заключение</title><p>Заключение. Оценка уровня экспрессии генов рецептора NMDA может быть использована в качестве генетического маркера для определения токсического действия наночастиц оксида меди, однако необходимы дальнейшие исследования, включающие проведение поведенческих тестов, которые позволили бы подтвердить наличие клинических проявлений нейродегенеративных расстройств.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Copper plays an important role in the metabolism of the brain, but particles of copper, in the nanometer range, exhibit neurotoxic properties and cause malfunctioning of brain cells.</p></sec><sec><title>Material and methods</title><p>Material and methods. For 6 weeks, 3 times a week, the animals were injected with a suspension of NPs of copper oxide. The determination of the expression of the genes GRIN1, GRIN2a, and GRIN2b, encoding the proteins GluN1, GluN2a, and GluN2b, respectively, was carried out by real-time PCR with probes.</p></sec><sec><title>Results</title><p>Results. A statistically significant decrease in the expression level of genes encoding NMDA receptor proteins was determined when exposed to 0.5 mg/ml CuO nanoparticles (ΔCt(GRIN1) = 0.813; ΔCt(GRIN2A) = 3.477; ΔCt(GRIN2B) = 1.37) in comparison with control group (ΔCt(GRIN1) = 6.301; ΔCt(GRIN2A) = 7.823; ΔCt(GRIN2B) = 4.747).</p></sec><sec><title>Conclusion</title><p>Conclusion. Evaluation of gene expression of the NMDA receptor may be present in a genetic marker to determine the toxic effect of copper oxide nanoparticles; however, further studies are needed, including behavioral tests to confirm the clinical manifestations of neurodegenerative disorders.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>наночастицы</kwd><kwd>оксид меди</kwd><kwd>экспрессия генов</kwd><kwd>рецепторы NMDA</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanoparticles</kwd><kwd>copper oxide</kwd><kwd>gene expression</kwd><kwd>NMDA receptors</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">Уланова Т.С., Антипьева М.В., Забирова М.И., Волкова М.В.
