Дисбаланс в секреции адипокинов жировой тканью при ожирении может играть роль в развитии сердечно-сосудистых заболеваний. Нами было проведено исследование уровня экспрессии генов адипонектина и оментина-1 в жировой ткани у лиц с ожирением и ишемической болезнью сердца (ИБС). Показано, что сниженные концентрация в сыворотке крови и экспрессия гена адипонектина в подкожной жировой ткани могут вносить вклад в развитие ИБС при ожирении. ИБС ассоциирована с низкой концентрация оментина-1 в сыворотке крови. Imbalance in the secretion of adipose tissue adipokines may play a role in the development of cardiovascular diseases associated with obesity. Investigation of adiponectin and omentin-1 genes expression levels in adipose tissue was conducted in patients with obesity and coronary artery disease (CAD). Our study has shown that reduced adiponectin serum concentration and subcutaneous adipose tissue gene expression may contribute to CAD development. CAD is associated with a low serum omentin-1 concentration.

Abstract Background Psoriasis is a common chronic inflammatory condition associated with an increased risk of obesity and higher coronary atherosclerosis burden by coronary computed tomography angiography (CCTA). Prior studies have shown that the ability to expand subcutaneous adipose tissue (SAT) may serve to identify individuals at a lower risk of atherosclerotic cardiovascular disease. However, the relationship between abdominal SAT and high-risk subclinical coronary artery disease requires exploration. Purpose To characterize the relationship between abdominal SAT volume measured on low-dose computed tomography, and coronary artery disease assessed as noncalcified and lipid-rich necrotic core burden by CCTA in psoriasis. Methods We performed a cross-sectional study of 232 participants with psoriasis and without known cardiovascular disease. All participants underwent CCTA to characterize coronary artery disease burden and low dose abdominal computed tomography to quantify subcutaneous adipose tissue volumes. Fat depot volumes were first adjusted in a sex specific manner for each participant's body mass index in a linear regression model. The residual values from the sex stratified linear regression models were used for analyses. Coronary artery disease burden was quantified in the three main coronary arteries (QAngio, Medis, The Netherlands) and averaged. Analyses were performed with StataIC 16 (Stata Corp., College Station, TX, USA). Results Of the 232 participants, 92 (40%) were women and the average age was 50 years. In women, there was a positive correlation between abdominal SAT and systemic inflammation as assessed by hs-CRP (r=0.30; p=0.004) and GlycA (r=0.29; p=0.007) as well as total cholesterol (r=0.24; p=0.02) and LDL cholesterol (r=0.22; p=0.04). In men, abdominal SAT correlated with hs-CRP (r=0.18; p=0.04) and insulin resistance as assessed by the homeostatic model for insulin resistance (r=0.17; p=0.04). In models fully adjusted for traditional cardiovascular risk factors, abdominal SAT volume negatively associated with noncalcified and lipid-rich necrotic core burden in men (β=−0.17; p=0.03, β=−0.21; p=0.02, respectively), but not women (β=−0.04; p=0.72, β=0.05; p=0.68, respectively) with psoriasis (Table). Conclusions In psoriasis, for a given body mass index, abdominal SAT negatively associated with coronary atherosclerosis burden in men. The observed sex-specific effects on subclinical coronary artery disease warrant further study of abdominal SAT in states of chronic inflammation.

Background: The prevous studies has showed that serum retinol binding protein 4 (RBP4) levels increased in metobolic disorders which are closely associated with cardiovascular dieases (CVD).  However the human studies investigating the role of RBP4 in CVD are conflicted. Therefore, we aimed to evaluate the relationship between RBP4 and the presence and the severity of coronary artery disease (CAD) in this study. Methods: 55 patients with presenting acute coronary syndrome (ACS) and 43 control subjects who had various cardiovascular risk factors with normal coronary artery on coronary angiography were included in this study.The serum RBP4 concentrations were measured using ELISA method and clinically and anatomically score models were used to asses the severity of coronary lesion. Results: Serum RBP4 level was significantly higher in patients with ACS compared to the controls (68.40 ± 47.94 mg/L vs. 49.46 ± 13.64 mg/L; p = 0.014).  RBP4 was correlated with GENSINI and SYNTAX I score (r = 0,286 p=0,034; r = 0.403 p = 0.002 respectively). However, there was no relationship between RBP4 and GRACE score. Conclusion: Patients with ACS had increased serum RBP4 levels and its high levels were correlated with CAD severity.

Дисбаланс в секреции адипокинов жировой тканью может играть роль в развитии сердечно-сосудистой патологии при ожирении. Оментин-1, один из адипокинов жировой ткани, обладает противовоспалительным, антиоксидантным, антиатерогенным эффектами. Снижение концентрации оментина-1 в сыворотке крови может рассматриваться как биомаркер сердечно-сосудистых заболеваний. Цель работы - исследование экспрессии гена оментина-1 (ITLN1) в подкожной жировой ткани (ПЖТ) у пациентов с ишемической болезнью сердца (ИБС) и в группе сравнения, включающее сравнительный анализ уровня мРНК и белка в ПЖТ, концентрации оментина-1 в сыворотке крови, а также оценку корреляции экспрессии гена ITLN1 и гена ключевого транскрипционного регулятора адипогенеза - рецептора, активируемого пероксисомным пролифератором, гамма (PPARG). Были исследованы образцы ПЖТ и сыворотки крови 74 пациентов с ИБС, перенесших операцию коронарного шунтирования, и 16 пациентов (группа сравнения), оперированных по поводу клапанных пороков сердца. Уровень мРНК генов ITLN1 и PPARG в ПЖТ оценивали методом ПЦР в реальном времени. Уровень белка оментина-1 в ПЖТ определяли методом вестерн-блот. Концентрацию оментина-1 в сыворотке крови измеряли методом ИФА. Концентрация оментина-1 в сыворотке крови была ниже в группе пациентов с ИБС, чем у обследованных из группы сравнения (р<0,01), и отрицательно коррелировала с окружностью талии у всех обследованных (r=-0,307, p<0,01). Не было выявлено различий в содержании мРНК гена ITLN1 и белка оментина-1 в ПЖТ между исследуемыми группами. Уровень мРНК гена ITLN1 коррелировал с уровнем белка оментина-1 в ПЖТ (r=0,373, р<0,05). Более высокий уровень белка оментина-1 в ПЖТ был выявлен у мужчин по сравнению с этим показателем у женщин (р<0,05), однако у женщин концентрация оментина-1 в сыворотке крови была выше, чем у мужчин (р<0,05). Уровень мРНК гена PPARG в ПЖТ был ниже у пациентов с ИБС (р<0,05). Концентрация оментина-1 в сыворотке крови положительно коррелировала с уровнем мРНК гена PPARG в ПЖТ (r=0,338, p<0,05). Среди всех обследованных уровень мРНК гена ITLN1 и уровень белка оментина-1 в ПЖТ отрицательно коррелировали с мРНК гена PPARG в ПЖТ (r=-0,444, p<0,01 и r=-0,475, p<0,01, соответственно). Аналогичные корреляции сохранялись для подгруппы мужчин (r= -0,422, p<0,05 и r= -0,609, p<0,01, соответственно). ИБС, ожирение и мужской пол ассоциированы со снижением концентрации оментина-1 в сыворотке крови. Установлены гендерные особенности регуляции экспрессии гена оментина-1 в ПЖТ. Imbalance in secretion of adipose tissue adipokines may play a role in the development of cardiovascular pathology associated with obesity. Omentin-1 is an adipokine with antiinflammatory, antioxidant and antiatherogenic properties, therefore it’s serum concentration is considered as a biomarker of cardiovascular diseases. Objective: Investigation of omentin-1 gene (ITLN1) expression in SAT in coronary artery disease (CAD) patients and in the control group, including сomparative analysis of ITLN1 mRNA and protein levels in SAT, omentin-1 serum concentration, as well as an assessment of the correlation of the ITLN1 gene expression with the mRNA level of PPARG gene encoding peroxisome proliferator-activated receptor gamma as the key regulator of adipogenesis. Subcutaneous adipose tissue (SAT) biopsies and serum samples from 74 patients with CAD, undergoing coronary artery bypass grafting, and 16 persons of the control group, were included in the study. ITLN1 and PPARG mRNA levels were detected by quantitative real-time PCR. Omentin-1 protein level in SAT was measured by western-blot. Serum omentin-1 concentration was determined by ELISA. Serum omentin-1 concentration was decreased in the CAD group compared to controls (p<0,01), and inversely correlated with waist circumference among all examined individuals (r = -0.307, p <0.01). No differences were found in the ITLN1 mRNA and omentin-1 protein levels in SAT between the studied groups. The ITLN1 mRNA and omentin-1 protein levels in SAT were positively correlated (r=0,373, p<0.05). A higher level of omentin-1 protein in SAT was detected in men compared with women (p <0.05), however, omentin-1 serum concentration was higher in women (p <0.05). The PPARG mRNA level in SAT was lower in patients with CAD (p <0.05). Omentin-1 serum concentration was positively correlated with the PPARG mRNA level in SAT (r =0.338, p <0.05). The ITLN1 mRNA and omentin-1 protein levels were negatively correlated with the PPARG mRNA in SAT among all examined individuals (r = -0.444, p <0.01 and r = -0.475, p <0.01, respectively). These correlations persisted only in men subgroup when men and women were analyzed separately (r= -0,422, p<0,05 and r= -0,609, p<0,01, respectively). CAD, adiposity and male gender are associated with reduced omentin-1 serum concentration. Gender differences of omentin-1 gene expression regulation in SAT were demonstrated.
