Мышам проведена трансплантация культивированных изогенных клеток костного мозга (ККМ) от гетерозиготных db/+ доноров. Реципиенты были разделены на группы по разным стадиям развития МС — ранняя и выраженная. Проанализирована экспрессия гена Lep на 3-и, 8-е и 14-е сут после введения стволовых ККМ в клетках головного мозга, печени и поджелудочной железы методом полимеразной цепной реакции (ПЦР) в режиме реального времени. Экспрессию гена Lep оценивали в количестве копий кДНК. Согласно данным нашей лаборатории, лептин является полноценным регулятором обменных процессов за счет своего влияния на гипоталамус, который, в свою очередь, совместно с гиппокампом, контролирует продукцию ацетилхолина и инсулина в мозге. Нами доказана роль Lep гена как количественного оценочного критерия эффективности клеточной терапии при МС.</p></abstract><trans-abstract xml:lang="en"><p>It is shown that the level of the Lep gene expression is a marker for B/Ks-Leprᵈᵇ/+ mice, which line serves as an optimal model for describing metabolic syndrome (MS) in preclinical studies. Mice were transplanted with cultured isogenic bone marrow cells (BMC) from heterozygous db/+ donors. The recipients were divided into two groups according to an early or advanced stage of MS development. We analyzed the expression of the Lep gene on the 3rd, 8th and 14th day following the administration of stem BMCs in the brain, liver and pancreas cells by polymerase chain reaction (PCR) in real time. The Lep gene expression was evaluated in terms of the number of cDNA copies. According to our data, leptin is a complete regulator of metabolic processes due to its effect on the hypothalamus, which, together with the hippocampus, controls the production of acetylcholine and insulin in the brain. We have proven the role of the Lep gene as a quantitative criterion for evaluating the effi cacy of a cell therapy in MS.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кДНК</kwd><kwd>метаболический синдром (МС)</kwd><kwd>мыши линии B/Ks-Leprᵈᵇ/+</kwd><kwd>экспрессия гена</kwd><kwd>ген лептина Lep</kwd><kwd>стволовые клетки костного мозга (СККМ)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cDNA</kwd><kwd>metabolic syndrome (MS)</kwd><kwd>B/Ks-Leprᵈᵇ/+ mice</kwd><kwd>gene expression</kwd><kwd>Lep leptin gene</kwd><kwd>bone marrow stem cells (BMSC)</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Автор выражает благодарность научному руководителю — директору ФГБУН «Научный центр биомедицинских технологий Федерального медико-биологического агентства России», д. м. н., проф.
