Abstract
Background Adipokine chemerin was proven to be associated with coronary artery disease (CAD), but its prognostic implications in CAD remain unclear. Methods This study consists of two parts, one is a basic study and the other is a clinical cohort study. First, we investigated the differential expression of six adipokines in the atherosclerotic mice model compared to mice with milder degrees of atherosclerosis and mice without atherosclerosis using microarray data. We then examined the potential of chemerin as a diagnostic and prognostic indicator in a CAD cohort. A total of 152 patients were enrolled in our study, including 77 patients with angiographically proven CAD and 75 control subjects without cardiovascular disease. Plasma adipokine chemerin levels were measured in all patients, and major adverse cardiovascular events (MACEs) were followed up, including ischemic stroke, non-fatal myocardial infarction, revascularization, and cardiovascular death. Results In the aortas of atherosclerotic mice, chemerin expression was up-regulated compared to control mice. The plasma chemerin levels of CAD patients were higher than those of non-CAD patients (128.93 ± 37.06 vs. 109.85 ± 27.47 mmol/L, respectively, P < 0.001). High chemerin levels were an independent predictor of CAD (β = 2.702, 95% CI, 1.344–5.431, P = 0.001). We followed up with patients for a median duration of 5.5 years (3.9–5.6). The Kaplan–Meier curves showed that patients in the high chemerin group had a significantly higher risk of MACEs than the low chemerin group in patients with CAD (log-rank P = 0.003), not with non-CAD (Log-rank P = 0.120). Furthermore, Cox multivariate analysis revealed that high chemerin levels were an independent predictor of MACEs (HR 2.267; 95% CI, 1.139–4.515; P = 0.020). Finally, the cellular study showed that chemerin is predominantly expressed in PBMC-derived macrophages. Conclusion Plasma chemerin levels were increased in the CAD patients, and a high chemerin level increased the risk of MACEs in CAD patients.

Vaspin in atherosclerotic disease and cardiovascular risk in axial spondyloarthritis: a genetic and serological study. Arthritis Res Ther 2021; 23:111. [PMID: 33849644 PMCID: PMC8042971 DOI: 10.1186/s13075-021-02499-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 03/31/2021] [Indexed: 12/16/2022] Open
Abstract
Background Vaspin is a novel anti-inflammatory adipokine associated with cardiovascular (CV) disease and inflammation in chronic inflammatory conditions different from axial spondyloarthritis (axSpA). Given the high incidence of CV disease (mainly due to accelerated atherosclerosis) exhibited by axSpA patients, we wondered if vaspin could also be a key molecule in this process. However, data on the role of vaspin regarding atherosclerotic disease in the context of axSpA is scarce. For this reason, we aimed to evaluate the implication of vaspin, at the genetic and serological level, in subclinical atherosclerosis and CV risk in axSpA. Methods This study included 510 patients diagnosed with axSpA. Carotid ultrasound (US) was performed to evaluate the presence of subclinical atherosclerosis. Three vaspin gene variants (rs2236242, rs7159023, and rs35262691) were genotyped by TaqMan probes. Serum vaspin levels were assessed by enzyme-linked immunosorbent assay. Statistical analysis was performed using STATA® v.11.1. Results Serum vaspin levels were significantly higher in female patients than in males and also in obese patients when compared to those with normal weight (p < 0.05). At the genetic level, we disclosed that the minor allele of rs2236242 (A) was associated with lower serum vaspin levels in axSpA, while the rs7159023 minor allele (A) was linked to higher serum levels (p < 0.05). When the three polymorphisms assessed were combined conforming haplotypes, we disclosed that the TGC haplotype related to high serum levels of vaspin (p = 0.01). However, no statistically significant association was observed between vaspin and markers of subclinical atherosclerosis, both at the genetic and serological level. Conclusions Our results revealed that vaspin is linked to CV risk factors that may influence on the atherosclerotic process in axSpA. Additionally, we disclosed that serum vaspin concentration is genetically modulated in a large cohort of patients with axSpA.

Abstract
BACKGROUND In recent years, the role of vaspin as an insulin-sensitizer has been studied widely. This is the investigation that examined the association of vaspin polymorphism rs2236242 on the vaspin level and the risk of type 2 diabetes and insulin-resistant Iranian pre-diabetic/diabetic population. METHODS A case-control study was conducted on 160 participants includes 80 participants holding (FBG) fasting blood glucose 3.88-5.55 (mmol/L) in the normal group, and 80 participants holding FBG≥5.55 (mmol/L) in a diabetic/pre-diabetic group. The serum vaspin and insulin were determined with ELISA (enzyme-linked assay) and biochemical variables by standard method. Tetra arms amplification system for the vaspin gene was performed. Statistical analysis was done using SPSS software version 20. RESULTS The means of age, body mass index (BMI), waist circumference (WC), hip circumference (HC), FBG, and vaspin were significantly different between normal and type 2 diabetic/impaired fasting blood group (P-value<0.05). rs2236242 showed association with Hip circumference (P-value<0.05). A significant association between allele A of rs2236242 with type 2 diabetes was seen (P-value<0.001). The vaspin levels showed a negative correlation with FBG (r =-0.296, P=0.001). CONCLUSIONS Allele A of rs2236242 is a protective risk for type 2 diabetes, but no association of rs2236242 with insulin resistance was seen. The lower level of vaspin is a predictor for the progression of type 2 diabetes.

Abstract
Coronary artery disease (CAD) is the primary cause of death worldwide. Vaspin was a recently described adipokine, playing a protective role in many metabolic and cardiovascular diseases. This study aimed to assess the relation of serum vaspin levels and vaspin rs2236242 polymorphisms with CAD. The study included 105 healthy subjects and 105 CAD patients. Serum vaspin concentrations and vaspin rs2236242 polymorphisms were determined by enzyme-linked immunosorbent assay and polymerase chain reaction, respectively. There was a statistically significant difference between the genotypes of CAD patients (TT 26.7%, TA 71.4%, and AA 1.9%) and controls (TT 70.5%, TA 28.6%, and AA 1%; χ2 = 40.3; df = 2; p = .000). The TA genotype increased the risk of CAD (odds ratio [OR] = 6.60; 95% confidence interval [CI] = 3.60-12.1; p = .000) as compared to the TT genotype. There was a statistically significant difference between the allelic distribution of CAD patients (T 62.4% and A 37.6%) and controls (T 84.8% and A 15.2%; χ2 = 27.0; df = 1; p = .000). Those carrying the A allele had a higher risk of CAD compared to those with the T allele (OR = 3.35; 95% CI = 2.10-5.36; p = .000). The serum vaspin concentrations of the patients with TT, TA, and AA genotypes were 30.4 ± 1.72, 28.4 ± 2.89, and 36.4 ± 6.38 pg/ml, respectively, and there was no significant difference between the serum vaspin levels and vaspin genotypes (p = .696). All of the above suggested that the vaspin rs2236242 polymorphism was associated with CAD in the Turkish population.

Abstract
Purpose/Aim: So far no research concerning the omentin-1 (ITLN1) rs2274907 and vaspin (SERPINA12) rs2236242 polymorphisms has been carried out in a healthy pediatric population. We analyzed associations of these polymorphisms with anthropometric parameters, lipid profile, as well as adiponectin, leptin and soluble leptin receptor (sOB-R) levels in prepubertal healthy children, to search for their possible role in the risk of obesity and obesity-related disorders.Materials and Methods: Frequencies of these polymorphisms were analyzed by the restriction fragment length polymorphism in 89 normal-weight children. The body composition was measured by dual-energy X-ray absorptiometry. Serum levels of adipokines were measured using ELISA methods.Results: We observed differences in values of HDL-cholesterol (p = 0.002) and triglycerides (p = 0.039) in children carrying different genotypes of the ITLN1 rs2274907 polymorphism. In children carrying different genotypes of the SERPINA12 rs2236242 polymorphism differences in BMI (p =0.025) and BMI Z-score (p = 0.01) values were found. Significant relations between anthropometric parameters and levels of HDL-cholesterol and triglycerides were associated with minor alleles of the studied polymorphisms. In addition, leptin/sOB-R ratio was related to HDL-cholesterol (p = 0.004) and triglycerides (p = 0.03) levels in children carrying minor allele of the SERPINA12 rs2236242 SNP.Conclusions: We suggest that both ITLN1 rs2274907 and SERPINA12 rs2236242 polymorphisms influence body composition and lipid profile in prepubertal healthy children. Relations between anthropometric parameters, lipid and adipokine levels may be associated with minor alleles of the studied polymorphisms. The possible role of these polymorphisms in the modulation of the risk of obesity and obesity-related disorders in the later life might be considered.

Abstract
Vaspin, an insulin-sensitizing adipokine, has been associated with type 2 diabetes (T2D). The present study aimed to investigate the distribution of genotypes and high-risk alleles of vaspin genetic variants (rs77060950 G/T and rs2236242 A/T), in Gujarat subpopulation (India). Genomic DNA isolated from PBMCs was used to genotype vaspin polymorphisms by PCR-RFLP and ARMS-PCR from 502 controls and 478 patients. RNA isolated from visceral adipose tissue (VAT) of 22 controls and 20 patients was used to assess vaspin transcript levels by qPCR while the vaspin titre of the subjects was assayed using ELISA. Phenotypic characteristics of Fasting Blood Glucose (FBG), BMI and plasma lipid profile were estimated and analyzed for the genotype-phenotype correlation. We identified a significant association of rs2236242 A/T with T2D as the TT genotype conferred a 3.087-fold increased risk. The TT genotype showed association with increased FBG, BMI and Triglycerides levels. Increased GA, GT and TA haplotype frequencies, decreased VAT transcript and vaspin protein levels in T2D patients was observed, which were further negatively correlated with FBG and BMI. In conclusion, rs2274907 A/T polymorphism is strongly associated with reduced vaspin transcript and protein levels, and related metabolic alterations that may play a role in the advancement of T2D.

Abstract
The relationship between serum vaspin levels and metabolic or coronary artery disease is currently of interest for researchers. Although adipokine concentrations have been shown to be increased significantly in atherosclerotic lesions, the role adipokines in the atherosclerotic process
remains to be elucidated. Vaspin is a new biological marker associated with obesity and impaired insulin sensitivity. Plasma vaspin concentration has been shown to correlate with the severity of coronary artery disease. Vascular inflammation triggered by vaspin inhibits atherogenesis by suppressing
macrophage foam cell formation and vascular smooth muscle cell migration and proliferation. Vaspin also contributes to plaque stabilization by increasing collagen content and reducing the intraplaque macrophage to vascular smooth muscle cell ratio. The therapeutic goal concerning vaspin is
to fight atherosclerosis and related diseases, as well as to maintain vascular health.

Abstract
AIM Vaspin is an adipokine separated from visceral fat tissues of obese diabetic rats. This study was to investigate the association between vaspin rs2236242 gene polymorphism and type 2 diabetes mellitus (T2DM) or obesity in a Chinese population. MATERIALS AND METHODS T2DM patients and nondiabetic controls were recruited from Qingpu Branch of Zhongshan Hospital Affiliated to Fudan University (Shanghai, China) from May 1, 2015 to June 30, 2017. Clinicopathologic characteristics were recorded and their blood samples were collected. Serum vaspin levels were detected by enzyme-linked immunosorbent assay and vaspin rs2236242 genotypes by tetra-amplification refractory mutation system-polymerase chain reaction. RESULTS Two hundred and ninety-nine patients with T2DM and 311 controls were recruited at last. The vaspin genotypes of diabetic patients were distinct from nondiabetic controls (χ 2 = 54.611, p < 0.0001). Genotyping revealed that T2DM patients have a greater prevalence of A allele compared with controls (61.9% vs. 42.1%, p < 0.0001). A allele was associated with an increased risk of T2DM (odds ratio = 2.23, 95% confidence interval = 1.773-2.804, p < 0.0001) compared with T allele. The genotype distribution did not differ among nondiabetic subjects with or without obesity. The serum vaspin levels were higher in T2DM patients and obese controls than the nonobese controls, however, the rs2236242 was not found to be significantly related to serum vaspin levels. CONCLUSIONS Our findings showed the association between vaspin rs2236242 gene variants with obesity and T2DM in a Chinese population. People with rs2236242 A allele had a 2.23-fold increased risk of T2DM. These findings suggest that vaspin rs2236242 may serve as a potential diagnostic and/or therapeutic targets for T2DM.

Abstract
BACKGROUND Our study aims to explore the association of rs7025486 single-nucleotide polymorphisms (SNP) in DAB2IP and rs1333049 on chromosome 9p21.3 with the coronary artery disease in Chinese population. METHODS All patients came from the east China area and underwent coronary angiography. Rs7025486 and rs1333049 polymorphism were genotyped in 555 patients with CAD and in 480 healthy controls that underwent coronary angiography. RESULTS In Chinese population, the rs7025486 genotype in the case group was no significant different than the control group (P = 0.531).Meanwhile, the rs1333049 SNP has statistically significant (P = 0.006), which was the independent risk factors for CAD (OR1.252, P = 0.039), and consistent with the past studies conclusion. CONCLUSION Genotype of rs1333049 on chromosome 9p21, but not rs7025486 on chromosome 9q33, is an independent determinant of the incidence of CAD in Chinese population.

Vaspin regulates the osteogenic differentiation of MC3T3-E1 through the PI3K-Akt/miR-34c loop. Sci Rep 2016; 6:25578.

Abstract
Vaspin (visceral adipose tissue-derived serine protease inhibitor) is a newly discovered adipokine that widely participates in diabetes mellitus, polycystic ovarian syndrome and other disorders of metabolism. However, the effect of vaspin on the regulation of osteogenesis and the mechanism responsible are still unclear. Here, we found that vaspin can attenuate the osteogenic differentiation of the preosteoblast cell line MC3T3-E1 in a dose-dependent way; also, during this process, the expression of miRNA-34c (miR-34c) was significantly increased. Down-regulation of the expression of miR-34c in MC3T3-E1 diminished the osteogenic inhibitory effect of vaspin, while the up-regulation of miR-34c increased this effect through its target gene Runx2. Meanwhile, we found that vaspin could also activate the PI3K-Akt signalling pathway. Blocking the PI3K-Akt signalling pathway with specific inhibitors could decrease the osteogenic inhibitory effect of vaspin as well as the expression level of miR-34c. Furthermore, knock-down of miR-34c could promote the activation of Akt, which was probably realised by targeting c-met expression. Thus, PI3K-Akt and miR-34c constituted a modulation loop and controlled the expression of each other. Taken together, our study showed that vaspin could inhibit the osteogenic differentiation in vitro, and the PI3K-Akt/miR-34c loop might be the underlying mechanism.
