CIDE-A gene and the genes of LRP group play a key role in the regulation of the body weight and lipid metabolism in mammals. CIDE-A is defined as a potential human obesity gene and the LRP1 gene is associated with the development of abdominal aortic aneurysm (AAA). The aim of the study was to define the role of CIDE-A gene in patients with dyslipidemia and asymptomatic AAA. Material and methods. The study group consisted of 38 subjects, including 27 men and 11 women qualified for endovascular aneurysm repair (EVAR). The subjects with abdominal aortic aneurysm were enrolled in the study group, depending on the body mass index (BMI); in obese patients (BMI > 30). The control group (n = 16) included subjects without lipid disorders. One-step isolation of RNA from lymphocytes and adipose tissue cells was performed using the modified TRI method by Chomc-zynski and Sacchi, and then the gene expression was tested by real-time PCR. Results. The highest mean relative of the gene expression for CIDE-A was reported in subjects with the normal body weight. The lowest mean relative of the gene expression for CIDE-A was observed in the group of obese patients with aortic aneurysm and lipid disorders. A high negative correlation (r = -0.7101) in the gene expression for CIDE-A was observed in the group of obese patients with aortic aneurysm, depending on the BMI. Conclusions. Due to the important role of the CIDE-A gene and Cide-A protein in the development of metabolic syndrome, obesity and the accompanying vascular lesions such as abdominal aortic an-eurysm, seen in this context, the tested gene and protein Cide-A represent a potential therapeutic target in these diseases.

According to the latest data, CIDE -A gene plays a key role in the regulation of body weight in both humans and mice, and therefore it is regarded a potential candidate gene for human obesity. The aim of the study was to define the role of CIDEA gene in patients with dyslipidemia and symptomatic limb ischemia. Material and methods. The study group contained 28 patients, including 17 men and 11 women. Patients were enrolled in the study group, depending on the value of body mass index (BMI); there was BMI>30 for obese patients. The group included untreated patients (n=14) and patients (n=14) receiving atorvastatin 20 mg/day for at least three months prior to the initiation of the study. The control group (n=16) contained patients with no lipid disorders. A one-step isolation of RNA from lymphocytes and adipose tissue cells was carried out using the TRI method modified by Chomczyński and Sacchi. Next, gene expression was tested using real-time PCR. Results. The highest mean relative expression of CIDE -A gene occurred in patients with normal body weight. The lowest mean relative expression of CIDE-A gene was observed in obese patients with lipid disorders. A high negative correlation (r=-0.7919) of CIDE -A gene expression, depending on BMI, was reported in the group of obese patients with lipid disorders. Conclusions. Due to an important role of Cide-A protein demonstrated in the development of metabolic diseases such as obesity, metabolic syndrome, type 2 diabetes and their vascular complications, CIDE -A gene and protein are potential therapeutic targets in the case of these diseases.
