    ABSTRACT: Background: Visceral adipose tissue-derived serine protease inhibitor (vaspin) is a recently identified adipokine. Studies suggest it is involved in many diseases such as obesity, diabetes and coronary artery disease (CAD). This study is to investigate the association of single nucleotide polymorphisms (SNPs) in vaspin with CAD and its potential mechanisms. Methods: A total of 1570 consecutive patients undergoing coronary angiography were enrolled and the genotypes were determined by TaqMan allelic discrimination. Serum vaspin concentrations and mRNA expression levels were determined by ELISA and RT-PCR, respectively. Reporter gene assay was performed to investigate the effect of polymorphism on vaspin promoter function. Results: After multivariate analysis, allele A of rs2236242 was found as an independent determinant of CAD (OR=1.32, p=0.004). Rs35262691 in vaspin promoter was associated with serum vaspin concentration and mRNA expression in peripheral blood mononuclear cells (PBMC) though no association had been found with CAD. Reporter gene assay further confirmed that CC genotype of rs35262691 had 2.1±0.4-fold higher activities than TT genotype in facilitating gene expression. Conclusions: Our results show that the variants of vaspin gene are associated with serum vaspin levels and risk for CAD in Chinese population.

    ABSTRACT: Vaspin was a recently identified adipokine, playing a protective role in many metabolic diseases. The present study aimed to investigate the association between vaspin plasma level and stable angina pectoris (SAP) and unstable angina pectoris (UAP). A total of 88 patients with angiographically-proved coronary artery disease (CAD) (SAP 47, UAP 41) and 103 control subjects without cardiovascular diseases were enrolled in this study. Circulating vaspin, mRNA expression of vaspin in peripheral blood mononuclear cells (PBMC), clinical parameters, lipid profile and high-sensitivity C-reactive protein (hsCRP) were assayed. The severity of CAD was also assessed according to the number of vessels diseased. There are significant differences in circulating vaspin levels and mRNA levels of PBMC between SAP and UAP groups (SAP 0.91±0.95 ng/mL and UAP 0.43±0.38 ng/mL, p<0.01 in circulating vaspin level; SAP 1.19±0.85 and UAP 0.82±0.56, p<0.05 in mRNA level of PBMC). An inverse correlation between the number of diseased vessels and plasma vaspin concentration was observed (r=-0.350, p<0.01) in the CAD group. Construction of receiver operating characteristic curves confirmed that vaspin plasma concentrations significantly differentiated CAD patients (area under the curve=0.684, p<0.001), as well as UAP (area under the curve=0.640, p<0.05). Decreased vaspin plasma levels and mRNA levels in PBMC were observed in patients with UAP. Low vaspin concentrations correlate with CAD severity. The findings suggested that vaspin could serve as a novel biomarker of CAD as well as UAP.

    ABSTRACT: Myeloid-related protein 8/14 (MRP8/14) is a stable heterodimer formed by two different calcium-binding proteins (MRP8 and MRP14). Studies have identified that MRP8/14 regulates vascular inflammation and serves as a novel marker of acute coronary syndrome. In this study, we evaluated the correlation between serum levels of MRP8/14, hsCRP, endogenous secretory receptor for advanced glycation end-products (esRAGE) and the occurrence of coronary artery disease (CAD), or carotid intima-media thickness (IMT) when CAD was not yet developed in diabetic patients. Serum levels of MRP8/14, esRAGE and hsCRP were measured in 375 diabetic patients. Then the results of those who had CAD were compared against who had not. Also, we investigated the associations between above-mentioned indicators and IMT of subjects without CAD in both diabetic group and non-diabetic one. Serum MRP8/14 was significantly higher in CAD than in non-CAD group (9.7 ± 3.6 ug/ml vs. 8.2 ± 3.0 ug/ml, P < 0.001). It was associated with severity of CAD (r = 0.16, P = 0.026). In non-CAD group, MRP8/14 was associated with IMT in patients with (r = 0.30, P < 0.001) or without diabetes (r = 0.26, P = 0.015). The areas under the curves of receiver operating characteristic for CAD were 0.63 (95% CI 0.57-0.68) for MRP8/14, 0.76 (95% CI 0.71-0.81) for hsCRP and 0.62 (95% CI 0.56 -0.67) for esRAGE. In summary, we report that diabetic patients with CAD had elevated plasma MRP8/14 levels which were also positively correlated with the severity of CAD and carotid IMT in patients without clinically overt CAD.
