The level of fasting plasma glucose and triacylglycerol (TAG) were measured using calorimetric assay. Blood pressure was measured using mercuric sphygmomanometer. Anthropometric measurements were done to each individual. Furthermore, MetS patients were defined according to the criteria proposed by the American Heart Association and divided into three groups according to MetS index.Results: The study was performed on three groups and a control group defined as follows: group 1: 15 MetS patients who fulfilled all diagnostic criteria of MetS; group 2: 20 MetS patients with normal blood pressure; group 3: 20 MetS patients with normal TAG levels.The levels of miRs are expressed as [median (IQR)]. miR-486-5-p and miR-497 expression were elevated in group 1 [31.9(49), p˂0.0001; 73.1(42.5), p˂0.0001], group 2 [36.4(15.7), p˂0.0001; 68.3(54.8), p˂0.0001], and group (3) [10.8(18.9), p=0.0014; 27.5(39.7), p=0.0012]. MiR-509-5p was elevated in groups 1 and 2 [501(468), p=0.0001], [309(436), p=0.0006], respectively, while normally expressed in group 3 [0.93(0.077), p=0.0001]. miR-605 was elevated in groups 1 and 3 [25.4(20.0), p=0.0018], [54.8(65.8), p˂0.0001], while normally expressed in group 2 [0.84(0.67), p˂0.0001].Conclusion: miRs (486-5p, 497, 509-5p, and 605) serum levels were higher in MetS patients than in healthy control subjects; therefore, these serum miRs can serve as early biomarkers and can be used to follow-up the prognosis of MetS.Keywords: metabolic syndrome (MetS), miR-486-5p, miR-497, miR509-5p, miR-605, metabolic syndrome index (MSI)
