According to RETN +62G>A polymorphism, carriers with the A allele (GA/AA) had significantly increased resistin levels than subjects with the GG genotype, consequently, the RETN +62G>A polymorphism was found to be related to MS, biochemical parameters and anthropometric variables.
Several of these activities, together with the effect of ellagic acid on insulin, glycogen, phosphatases, aldose reductase, sorbitol accumulation, advanced glycation end-product formation, and resistin secretion, may explain its effects on metabolic syndrome and diabetes.
The present results point that high leptin, resistin and ghrelin levels may be involved in the early pathophysiological process which can lead to later obesity and MeS in patients with bipolar disorder.
A concentration of leptin > 52.18 pg/ml (AUC = 0.81, <i>p</i> < 0.0001) and resistin > 4419.27 ng/ml (AUC = 0.67, <i>p</i> = 0.049) had a good predictive value for improvement of the LVEF in the patients without MeS.
Increased resistin in TJA+MetS, but not in TJA-MetS, compared to normal, suggests that while elevated resistin levels may be associated with the osteoarthritic process, levels are further attenuated by MetS, which is highly prevalent in this population.
Obesity was associated with higher adiponectin-resistin index value in sera (P < 0.0001) and decreased in subcutaneous adipose tissue (P < 0.001), but only adiponectin-resistin index measured in sera was significantly higher in obese with the metabolic syndrome (P = 0.04).
Although the associations between adiponectin, leptin, resistin and metabolic abnormalities in our paediatric population were similar to those in adults, correlations of FGF21 levels with obesity, IR and MetS were the inverse of those found in adults.
Therefore, we conducted a genome-wide association study (GWAS) to identify quantitative trait loci associated with resistin levels and investigated whether these variants were prospectively associated with the development of metabolic syndrome (MetS) and T2DM in an independent community-based cohort, the CardioVascular Disease risk FACtors Two-township Study (CVDFACTS).
Present study shows that 420C/G polymorphism of resistin gene directly correlated to its high circulating level and metabolic risk factors, specifically markers of obesity and atherosclerosis, so it may have an important role in the development of metabolic syndrome and cardio metabolic diseases.
Glucose metabolism was assessed by static (glucose, insulin, adiponectin, leptin and resistin plasma concentrations) and dynamic (disposition index, insulin sensitivity index, HOMA-IR and acute insulin response to glucose) indices, performed at baseline and after 12 weeks of 4 dietary interventions (high saturated fatty acid (SFA), high monounsaturated fatty acid (MUFA), low-fat and low-fat-high-n3 polyunsaturated fatty acid (PUFA)) in 486 subjects with MetS.
Our data suggest that the presence of the -420C/G SNP of the resistin gene is associated with increased obesity and metabolic syndrome, although it is not different in subjects at high cardiovascular risk such as patients with myocardial infarction or patients with renal dysfunction compared with controls.
