На модели полуторачасовой окклюзии средней мозговой артерии крыс был проведен анализ влияния пептида на экспрессию ряда генов и белков, вовлеченных в сигнальные пути, приводящие к воспалению и гибели клеток в условиях ишемии-реперфузии. Показано, что пептид через 24 ч от начала окклюзии снижает повышенный при ишемии уровень экспрессии в ишемизированной ткани мозга крыс мРНК провоспалительных цитокинов и хемокинов IL-1α, IL-1β, IL-6, TNF-α, Cxcl2 и Ccl3. Пептид снижал повышенные при ишемии уровни экспрессии белков металлопротеиназы ММР-9, транскрипционного фактора c-Fos, активных JNK киназ и предотвращал ишемическое снижение уровня активного транскрипционного фактора CREB.</p></abstract><trans-abstract xml:lang="en"><p>The synthetic peptide ACTH (4-7) PGP accelerates the regression of neurological disorders in ischemic stroke, but the molecular mechanisms of its action are not completely known. On the model of an hour and a half occlusion of the rat middle cerebral artery, an analysis was made of the effect of the peptide on the expression of a number of genes and proteins involved in signaling pathways leading to inflammation and cell death under conditions of ischemia-reperfusion. It was shown that the peptide 24 hours after the onset of occlusion reduces the level of expression of mRNA of pro-inflammatory cytokines and chemokines IL-1α, IL-1β, IL-6, TNF-α, Cxcl2 and Ccl3 in ischemic brain tissue. The peptide decreased the levels of expression of proteins metalloproteinase MMP-9, transcription factor c-Fos, active JNK kinases wich were increased under ischemia, and prevented ischemic decrease in the level of active transcription factor CREB.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>семакс</kwd><kwd>ишемия</kwd><kwd>инсульт</kwd><kwd>экспрессия генов</kwd><kwd>semax</kwd><kwd>ischemia</kwd><kwd>stroke</kwd><kwd>gene expression</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
