Установлены тканеспецифические особенности экспрессии генов (TFAM, Drp1, MFN2, SOD, BAX), числа копий мтДНК в исследуемых депо у больных ожирением. Доказано, что изменение (снижение) числа копий мтДНК в инсулинзависимых тканях может оказывать протекторное действие на митохондрии, в условиях повышенного окислительного стресса.</p><p>Выявлено, что у больных без СД 2-го типа повышение продукции химерина способствует активации антиоксидатной системы в висцеральной жировой ткани, но не в печени. Напротив, у всех больных ожирением с СД 2 типа регистрировалось снижение (в сравнении с больными без СД 2 типа) плазменного уровня химерина.</p><p>Таким образом, низкое содержание химерина в плазме крови у больных с СД 2-го типа опосредует формирование дисфунции митохондрий в инсулинзависимых тканях (жировая ткань, печень). </p></abstract><trans-abstract xml:lang="en"><p>In obese patients, the relationship between the content of chemerin in blood plasma and the expression of genes TFAM, Drp1, MFN2, SOD, BAX, responsible for quality control of mitochondria, in insulin-dependent tissues (adipose tissue, liver) was revealed. The tissue-specific features of gene expression (TFAM, Drp1, MFN2, SOD, BAX), the number of mtDNA copies in the studied depots in obese patients were established. It has been proven that a change (decrease) in the number of mtDNA copies in insulin-dependent tissues can have a protective effect on mitochondria under conditions of increased oxidative stress. It was found that in patients without type 2 diabetes, an increase in chemerin production promotes the activation of the antioxidant system in the visceral adipose tissue but not in the liver. On the contrary, all obese patients with type 2 diabetes showed a decrease (compared with patients without type 2 diabetes) in the plasma level of chemerin. Thus, the low content of chemerin in the blood plasma in patients with type 2 diabetes mediates the formation of mitochondrial dysfunction in insulin-dependent tissues (adipose tissue, liver). </p></trans-abstract><kwd-group xml:lang="ru"><kwd>ожирение</kwd><kwd>СД 2 типа</kwd><kwd>митохондрии</kwd><kwd>химерин</kwd><kwd>печень</kwd><kwd>жировая ткань</kwd><kwd>мтДНК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>obesity</kwd><kwd>T2DM</kwd><kwd>mitochondria</kwd><kwd>chemerin</kwd><kwd>liver</kwd><kwd>adipose tissue</kwd><kwd>mtDNA</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The research was supported by the Russian Foundation for Basic Research and Kaliningrad Region (No. 19-415-393004-r_mol_a to Daria Skuratovskaia, 19-44-390005-r_a to Daria Skuratovskaia); State assignment in the field of scientific activity (No. FZWM-2020-0010 to Larisa Litvinova); State Support of Leading Scientific Schools of the Russian Federation (No. 2495.2020.7 to Larisa Litvinova).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Begriche K., Massart J., Robin M.A., Bonnet F., Fromenty B.
