Перегрузка β-окисления жирных кислот, цикла трикарбоновых кислот и окислительного фосфорилирования приводит к снижению уровня АТФ и повышению образования активных форм кислорода. В норме, митохондрии способны эффективно удалять повышенный уровень активных форм кислорода с помощью антиоксидантной системы и метаболической адаптации клетки к измененным условиям. Целью данного исследования явилось изучение роли печеночной экспрессии SOD в патогенезе НАЖБП при ожирении. Было выявлено, что уровень экспрессии SOD1 в печени у больных ожирением с и без СД 2 типа с ИМТ &gt; 40 кг/м2 был ниже, чем у здоровых доноров. Число копий митохондриальной ДНК (мтДНК) в печени у всех больных ожирением было ниже более чем в два раза относительно значений контрольной группы. В печени у больных ожирением без СД 2 типа уровень белка SOD1 и число копий мтДНК были взаимосвязаны между собой и отрицательно коррелировали с площадью жировых включений. Таким образом, у больных ожирением снижение антиоксидантной защиты в печени приводит к уязвимости митохондрий, что, в свою очередь, способствует прогрессированию стеатоза и инсулинорезистентности. </p></abstract><trans-abstract xml:lang="en"><p>Steatosis in the liver in obesity increases the work of mitochondria to utilize excess lipids. An overload of β-oxidation of fatty acids, the tricarboxylic acid cycle, and oxidative phosphorylation leads to a decrease in ATP and an increase in the formation of reactive oxygen species. Normally, mitochondria can efficiently remove elevated levels of reactive oxygen species using the cell's antioxidant system and metabolic adaptation to altered conditions. This study aimed to investigate the role of hepatic SOD expression in the pathogenesis of NAFLD in obesity. It was found that the level of SOD1 expression in the liver in obese patients with and without type 2 diabetes with a BMI &gt; 40 kg/m2 was lower than in healthy donors. The copy number of mitochondrial DNA (mtDNA) in the liver in all obese patients was more than two times lower than in the control group. In the liver of obese patients without type 2 diabetes, the SOD1 protein level and the mtDNA copy number were interrelated and negatively correlated with the area of fatty inclusions. Thus, in obese patients, a decrease in antioxidant defense in the liver leads to the vulnerability of mitochondria, which, in turn, contributes to the progression of steatosis and insulin resistance.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ожирение</kwd><kwd>СД 2 типа</kwd><kwd>супероксиддисмутаза</kwd><kwd>мтДНК</kwd><kwd>печень</kwd><kwd>стеатоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>obesity</kwd><kwd>T2DM</kwd><kwd>superoxide dismutase</kwd><kwd>mtDNA</kwd><kwd>liver</kwd><kwd>steatosis</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, No. 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">Ferramosca A., Di Giacomo M., Zara V.
