Porcine Visceral adipose Tissue Derived Serine Protease Inhibitor ELISA Kit

Gestational diabetes mellitus (GDM) is considered to be one of the most frequent medical complication observed among pregnant women. The role of adipokines in the pathogenesis of GDM remains strictly unknown. Different adipokines have been studied throughout gestation, and they have been proposed as biomarkers of GDM and other pregnancy-related complications; however, there is no biomarker reported for GDM screening at present. The aim of this study was to evaluate serum nesfatin-1 and vaspin levels in GDM and non-GDM women, to characterize the correlation between these adipokines, and to assess the potential role of circulating adipokines in the prediction of risk of gestational diabetes mellitus. Serum concentrations of nesfatin-1 and vaspin were measured in 153 women with GDM, and in 84 patients with uncomplicated pregnancy by enzyme-linked immunosorbent assay (ELISA) kits, according to the manufacturer's instructions. Circulating levels of nesfatin-1 and vaspin were significantly lower in the GDM group than in the control group. Nesfatin-1 levels were negatively correlated with vaspin levels. The results of this study point out the possible role of nesfatin-1 and vaspin as potential novel biomarkers for the prediction and early diagnosis of GDM. Further studies are necessary to evaluate the influence of nesfatin-1 and vaspin on glucose metabolism in the early stages of GDM.

Vaspin has recently been identified as novel adipokine with high expression in adipose tissue of obese and type 2 diabetic subjects and with potentially insulin-sensitising properties. However, the impact of vaspin gene variants on the risk of type 2 diabetes mellitus (T2DM) has not been determined yet. Therefore, the aim of our study was to investigate the association of vaspin single nucleotide polymorphisms (SNPs) with T2DM and obesity. We analysed the association between 25 vaspin SNPs and T2DM in initially healthy 35-84 year-old individuals of the population-based, cross-sectional German KORA F3 study and assessed the association with measures of obesity. Genotyping was carried out with matrix-assisted laser desorption/ionisation-time of flight mass spectrometry of allele-dependent primer extension products and associations with T2DM and obesity were analysed by logistic regression analysis. Our results demonstrate a significant association of vaspin SNP rs2236242 with T2DM in the KORA F3 study with the AA genotype bearing an increased risk (adjusted OR 2.35 [1.59; 3.46] versus AT/TT). This association appears to be independent of obesity. Our finding corroborates previous studies that suggested a link between the novel adipokine vaspin and glucose metabolism.
