Adipokine chemerin overexpression in trophoblasts leads to dyslipidemia in pregnant mice: implications for preeclampsia. Lipids Health Dis 2023; 22:12. [PMID: 36698175 PMCID: PMC9875463 DOI: 10.1186/s12944-023-01777-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Accepted: 01/17/2023] [Indexed: 01/26/2023] Open
Abstract
BACKGROUND The adipokine chemerin regulates adipogenesis and the metabolic function of both adipocytes and liver. Chemerin is elevated in preeclamptic women, and overexpression of chemerin in placental trophoblasts induces preeclampsia-like symptoms in mice. Preeclampsia is known to be accompanied by dyslipidemia, albeit via unknown mechanisms. Here, we hypothesized that chemerin might be a contributor to dyslipidemia. METHODS Serum lipid fractions as well as lipid-related genes and proteins were determined in pregnant mice with chemerin overexpression in placental trophoblasts and chemerin-overexpressing human trophoblasts. In addition, a phospholipidomics analysis was performed in chemerin-overexpressing trophoblasts. RESULTS Overexpression of chemerin in trophoblasts increased the circulating and placental levels of cholesterol rather than triglycerides. It also increased the serum levels of lysophosphatidic acid, high-density lipoprotein cholesterol (HDL-C), and and low-density lipoprotein cholesterol (LDL-C), and induced placental lipid accumulation. Mechanistically, chemerin upregulated the levels of peroxisome proliferator-activated receptor g, fatty acid-binding protein 4, adiponectin, sterol regulatory element-binding protein 1 and 2, and the ratio of phosphorylated extracellular signal-regulated protein kinase (ERK)1/2 / total ERK1/2 in the placenta of mice and human trophoblasts. Furthermore, chemerin overexpression in human trophoblasts increased the production of lysophospholipids and phospholipids, particularly lysophosphatidylethanolamine. CONCLUSIONS Overexpression of placental chemerin production disrupts trophoblast lipid metabolism, thereby potentially contributing to dyslipidemia in preeclampsia.

Abstract
(1) Background: Obesity is closely connected to the pathophysiology of cardiovascular diseases (CVDs). Excess fat accumulation is associated with metabolic malfunctions that disrupt cardiovascular homeostasis by activating inflammatory processes that recruit immune cells to the site of injury and reduce nitric oxide levels, resulting in increased blood pressure, endothelial cell migration, proliferation, and apoptosis. Adipose tissue produces adipokines, such as chemerin, that may alter immune responses, lipid metabolism, vascular homeostasis, and angiogenesis. (2) Methods: We performed PubMed and MEDLINE searches for articles with English abstracts published between 1997 (when the first report on chemerin identification was published) and 2022. The search retrieved original peer-reviewed articles analyzed in the context of the role of chemerin in CVDs, explicitly focusing on the most recent findings published in the past five years. (3) Results: This review summarizes up-to-date findings related to mechanisms of chemerin action, its role in the development and progression of CVDs, and novel strategies for developing chemerin-targeting therapeutic agents for treating CVDs. (4) Conclusions: Extensive evidence points to chemerin's role in vascular inflammation, angiogenesis, and blood pressure modulation, which opens up exciting perspectives for developing chemerin-targeting therapeutic agents for the treatment of CVDs.

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.

Abstract
Fundamentos A L-carnitina (LC) tem muitos efeitos benéficos em animais diabéticos e humanos, mas seu efeito regulatório sobre a quemerina como uma citocina inflamatória e seu receptor no estado diabético são desconhecidos. Objetivos O presente estudo teve como objetivo investigar o efeito regulatório da LC na expressão do receptor semelhante ao de quimiocina 1 e quemerina (CMKLRI) em tecidos adiposo e cardíaco de camundongos diabéticos. Métodos Sessenta camundongos NMARI foram divididos em quatro grupos, incluindo controle, diabético, diabético + suplementação com LC e controle + suplementação com LC. O diabetes foi induzido pela alimentação dos animais com dieta hipercalórica por 5 semanas e injeção de estreptozotocina. Os animais foram tratados com 300 mg/kg de LC por 28 dias. Nos dias 7, 14 e 28 após o tratamento, os níveis de mRNA e proteína da quemerina e CMKLRI nos tecidos cardíacos e adiposos de animais foram determinados utilizando análise por qPCR e ELISA. Os índices de resistência à insulina também foram medidos em todos os grupos experimentais. A diferença com p<0,05 foi considerada significativa. Resultados A expressão de quemerina e CMKLRI aumentou nos tecidos cardíaco e adiposo de camundongos diabéticos nos dias 14 e 28 após a indução do diabetes, concomitantemente com a incidência de resistência à insulina e níveis aumentados de quemerina circulante (p<0,05). O tratamento com LC causou uma diminuição significativa na expressão de ambos os genes nos tecidos estudados e redução dos sintomas de resistência à insulina e dos níveis séricos de quemerina (p<0,05). Conclusão Os resultados sugerem que o tratamento com LC pode diminuir a expressão de quemerina e CKLR1 em tecidos cardíacos e adiposos de animais experimentais obesos e diabéticos.

Abstract
Recent studies have revealed that fatty tissue, so far considered an energy storage organ, is also the source of many substances called adipokines, including chemerin which plays many important functions in the body. Chemerin stimulates adipocytes maturation and differentiation, as well as acts as a chemoattractant, which stimulates innate and acquired immunity. This adipokine participates in the early stages of acute inflammation as well as its suppression by reacting with the CMKLR1 receptor. In various diseases associated with inflammatory processes, the level of chemerin in the serum increases. It is also considered a marker for benign and malignant tumors. Explanation of the pathomechanisms involving this adipokine is of a high importance and may contribute to the development of new possibilities in the treatment of many diseases. The article presents the latest information on the role of chemerin in various pathological states, particularly in psoriasis.

Abstract
Background: Chemerin is an adipokine and a chemoattractant for leukocytes. Increased chemerin levels were observed in patients with coronary artery disease (CAD). We investigated associations between chemerin and biochemical measurements or body composition in CAD patients. Methods: In the study, we included patients with stable CAD who had undergone percutaneous coronary intervention (PCI) in the past. All patients had routine blood tests, and their insulin and chemerin serum levels were routinely measured. Body composition was assessed with the DEXA method. Results: The study group comprised 163 patients (mean age 59.8 ± years, 26% of females, n = 43). There was no significant difference in serum chemerin concentrations between patients with diabetes and the remaining ones: 306.8 ± 121 vs. 274.15 ± 109 pg/mL, p = 0.1. Chemerin correlated positively with the white blood cell (WBC) count, the neutrophil to lymphocyte ratio, hsCRP, all fractions of cholesterol, triglycerides, platelet count, fasting insulin, and c-peptide. Chemerin levels were also correlated with total fat mass but only in a subgroup with normal glucose metabolism. Conclusion: In patients with CAD, serum chemerin levels are correlated with inflammation markers, insulin resistance, and an unfavorable lipid profile. Correlation with fat mass is dependent on glucose metabolism status. Depending on the presence of diabetes/prediabetes, the mechanisms regulating chemerin secretion may be different.

Abstract
Atherosclerosis (AS), a chronic arterial disease, is characterized by endothelial dysfunction, inflammatory reactions and lipid accumulation in parallel with aberrant angiogenesis and vascular smooth muscle cell (VSMC) proliferation. Adipose tissue has been suggested to have an integral influence on metabolism and endocrine secretion, while there have been increasing concerns about the possible involvement of adipokines in cardiovascular diseases, including AS. Here, we focused on chemerin, an adipokine highly expressed in adipose tissue, with strong evidence of an association with inflammation, endothelial dysfunction, metabolic disorder, aberrant angiogenesis, VSMC proliferation and calcification. In this review, we discuss chemerin and its receptors in the pathogenesis of AS. However, the existing data assign various, even contradictory, roles to chemerin in atherosclerosis, such as inhibiting vascular calcification and impairing endothelial function. Current studies focusing on its anti- and pro-atherogenic effects have pinpointed its distinct role in specific cell types and contexts in the pathogenesis of atherosclerosis. Therefore, the gaps in current knowledge regarding the specific role played by chemerin in the etiology of AS require additional future studies. It seems reasonable to suggest that targeted chemerin therapy can be developed as an innovative approach for treating AS.

Abstract
Obesity is associated with a series of health problems. Adipocytes are a huge repository of energy as well as an important source of many adipokines. In obesity, adipocytes are dysfunctional with excessive production and secretion of pro-inflammatory adipokines, such as tumor necrosis factor α (TNF-α), leptin, and chemerin. Recent studies have revealed that chemerin plays an important role in modulating physiologic as well as pathophysiologic processes. For example, chemerin stimulates maturation and differentiation of pre-adipocytes, acts as a chemoattractant and facilitates innate and acquired immunity. Furthermore, chemerin participates in the early stage of acute inflammation by reacting with the ChemR23 receptor. In various inflammatory diseases, the serum chemerin is significantly increased. Additionally, chemerin is also considered as an important biomarker for benign and malignant tumors. Thus, elucidating the pathologic mechanisms of chemerin action may facilitate the development of new therapeutic modalities to treat diverse inflammatory diseases. In this review, we summarize current knowledge of chemerin and its role as an important regulator in modulating various inflammatory diseases. Mechanisms underlying chemerin function in diverse diseases are explored to better understand its biochemistry and mechanisms of action.

The adipokine chemerin retinoic acid receptor responder protein 2 (RARRES2) has been associated with insulin resistance, type II diabetes mellitus (T2DM), obesity, and metabolic syndrome (MetS). The impact of RARRES2 rs17173608 gene polymorphism on MetS and chemerin levels is not completely elucidated. This study included 100 patients with MetS and 68 healthy subjects (non-MetS group). The RARRES2 rs17173608 gene variant was analyzed by tetra amplification refractory mutation system polymerase chain reaction (T-ARMS-PCR). Circulating chemerin levels were determined by ELISA. Serum urea, creatinine, fasting blood glucose, glycated hemoglobin, and traditional lipid profile were measured by colorimetric methods. The estimated glomerular filtration rate (eGFR) and non-traditional lipid parameters were calculated.
Results
Serum chemerin levels were significantly higher in MetS than in non-MetS subjects, type II diabetics (T2DM) than non-diabetics, and overweight compared to lean subjects, but it did not differ significantly between patients with and without hypertension. Strikingly, newly diagnosed diabetic patients had significantly higher serum chermerin levels. Correlation and multiple linear regression analysis showed that serum chemerin levels and non-traditional lipid parameters were correlated significantly with the clinical criteria of MetS. Genotyping and allelic frequency distribution of RARRES2 rs17173608 gene polymorphism showed its significant association with MetS. The TT genotype of RARRES2 rs17173608 SNP was more distributed in T2DM in comparison with non-diabetics, and it was associated significantly with higher serum chemerin and higher glycated hemoglobin levels. RARRES2 rs17173608 GG genotype and G allele frequency were less distributed in T2DM patients than in non-diabetic patients.
Conclusions
The RARRES2 rs17173608 SNP might have an impact on chemerin levels and lipid parameters. The GG genotype and G allele may have a protective role towards the risk of T2DM but not for MetS. Serum chemerin and non-traditional lipid profile are significantly associated with MetS.

Abstract
Supplemental Digital Content is available in the text. Objective— Chemerin has been shown to be associated with inflammation and metabolic syndrome, which are in turn leading risk factors for atherosclerosis. A few clinical studies have concentrated on the role of chemerin in atherosclerosis but revealed divergent findings. Therefore, we aimed to investigate the association of plasma chemerin levels with different subclinical measurements of atherosclerosis in a population-based sample. Approach and Results— Linear and logistic regression models with different atherosclerotic parameters as subclinical outcomes were applied to analyze data from 4003 subjects of the SHIP (Study of Health in Pomerania). After adjustment for metabolic and inflammatory parameters, these models revealed no association of chemerin with carotid intima-media thickness, carotid plaque, or carotid stenosis but a significant inverse association between chemerin and ankle-brachial index. In detail, logistic regression analysis showed that a 25-ng/mL increase in chemerin was associated with a 30% higher odd (95% confidence interval, 1.20–1.41) of having an ankle-brachial index value below the 25th age- and sex-specific quartile. Conclusions— Our analyses revealed a modest inverse association between chemerin and ankle-brachial index that remained consistent after adjustment for metabolic and inflammatory parameters. The association of chemerin with carotid intima-media thickness, carotid plaque, or carotid stenosis was not significant after adjustment for the same confounder set. The investigated subclinical atherosclerotic parameters are representative for the atherosclerotic burden of different arterial regions and different disease stages. Thus, our results might suggest that the value of chemerin as a marker of higher atherosclerotic risk differs depending on the affected arterial region and disease stage.

Abstract
BACKGROUND IL-17A plays an important role in inflammatory responses in myocardial infarction (MI). IL-17A signals through its receptor, for which, Act1 (TRAF3IP2) functions as a key upstream adaptor in the pathway. AIM To compare frequencies of functional polymorphisms of TRAF3IP2 (rs13210247, rs33980500) between patients with MI and healthy controls. METHODS The selected SNPs were studied in 201 Iranian MI patients and 201 healthy blood donors from Fars Province by PCR-RFLP in association with clinicopathologic criteria of patients. CXCL1 plasma levels in 126 MI patients and 50 normal subjects were measured by ELISA. RESULTS A significant increase in the mutant (T) allele of TRAF3IP2 rs33980500 in patients with diastolic dysfunction of the heart (P = .01) was observed. The highest correlation, however, was observed between the TRAF3IP2 rs33980500 TT genotype and T allele with left main coronary artery stenosis (P = .01, P < .001; OR = 31.03). T allele of TRAF3IP2 rs33980500 was also associated with female gender, family history of cardiovascular disease, and mechanical complications of heart (P = .04, P = .02, and P = .01, respectively). Moreover, TRAF3IP2 rs13210247 (G) correlated with mechanical complications of the heart (P = .01). A significant increase in the plasma levels of CXCL1 chemokine in patients (P = .0006) associated with TT genotype of TRAF3IP2 (rs33980500) was observed (P = .04). CONCLUSION The gene variants of Act1 adaptor are associated with correlates of poor outcome in patients with MI and plasma CXCL1 levels.

Abstract
BACKGROUND The aim of this study was to investigate the effect of a six-week-long exercise program using outdoor exercise equipment on fitness, insulin resistance and adipocytokines among Korean elderly. METHODS A total of 47 participants were randomized into one of the following three groups; control, resistance exercise or combined exercise (aerobic and resistance exercise). The resistance exercise group completed three resistance types of exercise. The combined exercise group completed five exercises, including three resistance types of exercise and two aerobic types of exercise. Participants' body composition, fitness level, homeostasis model assessment of insulin resistance (HOMA-IR), and adipocytokines were measured at baseline and at the end of six weeks. RESULTS After six weeks of exercise training, participants in the combined exercise group exhibited significant reduction in insulin, HOMA-IR and chemerin levels, while significant reduction was observed in HOMA-IR only in the resistance exercise group compared with the control group. Meanwhile, six weeks of exercise training, whether resistance exercise alone or combined, significantly improved upper body muscular strength/endurance and physical function compared to the control group. CONCLUSIONS Six weeks of combined exercise using outdoor exercise equipment was effective in improving fitness, HOMA-IR, circulating chemerin levels, and other known risk factors of chronic diseases.

Abstract
Cardiovascular diseases (CVD) are the leading cause of death in the diabetic population. Obesity is a serious problem that has been linked with CVD and diabetes via a variety of adipokines. The aims of this study were to evaluate and correlate circulating chemerin, apelin, vaspin, and omentin-1 levels in obese type 2 diabetic Egyptian patients with coronary artery stenosis (CAS), and to assess their usefulness as noninvasive diagnostic biomarkers. Chemerin, apelin, vaspin, and omentin-1 levels were determined by enzyme immunoassay in coronary artery disease (CAD) I patients (45 non-obese, nondiabetic with CAS), CAD II patients (45 obese, diabetic with CAS), and 30 controls. Patients in CAD I and CAD II groups exhibited higher levels of chemerin and apelin together with lower levels of vaspin and omentin-1 than in controls. These alterations were more significant in CAD II than in CAD I patients. Additionally, adipokine levels were individually correlated with each other and with certain biochemical variables. Moreover, chemerin and vaspin levels could differentiate CAD II patients from CAD I and controls. Alterations of these adipokines may play a crucial role in the pathogenesis of CAS in obese type 2 diabetic Egyptian patients. Chemerin and vaspin could be used as markers to support diagnosis of CAS.

Abstract
PURPOSE Chemerin has been suggested to be linked to insulin resistance and type 2 diabetes mellitus (T2DM). However, the relationship between visceral adiposity and chemerin levels remains unclear in subjects with T2DM. In this study, we investigated the relationship between serum chemerin levels and visceral adiposity. MATERIALS AND METHODS This study included 102 subjects newly diagnosed with T2DM. The relationships between serum chemerin levels and clinical and biochemical parameters were examined. Multiple linear regression analysis was performed to determine the predictable factors of serum chemerin levels. RESULTS Serum chemerin levels showed significant positive correlations with body mass index (BMI), waist circumference (WC), visceral fat thickness (VFT), insulin levels, the homeostasis model assessment of insulin resistance, and levels of triglycerides (log-transformed) and high-sensitivity C-reactive protein, while showing significant negative correlations with high-density lipoprotein cholesterol. After adjusting for BMI and WC, VFT showed a significant relationship with serum chemerin levels (r=0.222, p=0.027). Moreover, VFT was an independent predictive factor of serum chemerin levels (β=0.242, p=0.041). CONCLUSION We demonstrated that chemerin is linked to metabolic syndrome components. Moreover, serum chemerin levels were associated significantly with obesity, especially visceral adipose tissue, in subjects with T2DM.

Abstract
The aims of this prospective study were to detect maternal serum chemerin level in patients with preeclampsia and investigate its association with disease severity and neonatal outcomes. Maternal serum chemerin levels were significantly elevated in severe preeclamptic women (394.72 ± 100.01 ng/ml) compared to mild preeclamptic women (322.11 ± 37.60 ng/ml) and healthy pregnant women (199.96 ± 28.05 ng/ml) (p = .001). Maternal serum chemerin levels were positively correlated with systolic and diastolic blood pressure, C-reactive protein levels, homeostasis model assessment of insulin resistance, proteinuria, AST, ALT, and duration of hospitalisation. Gestational week at delivery, birthweight, and APGAR scores at 1 and 5 min were negatively correlated with maternal serum chemerin level. A maternal serum chemerin level of >252.0 ng/ml indicated preeclampsia with 95.5% sensitivity and 95.7% specificity. There was a positive correlation between maternal serum chemerin level and severity of preeclampsia. Additionally, adverse neonatal outcomes were significantly associated with high maternal serum chemerin levels.

Abstract
Currently, coronary artery disease (CAD) is considered a major ailment in humans with widespread prevalence. CAD also accounts for high mortality rates around the world that involves several known risk factors. Chemerin is a novel adipokinine that is associated with inflammation and adipogenesis. Furthermore, experimental and clinical data indicate that localized as well as circulating chemerin expression and activation are elevated in numerous metabolic and inflammatory diseases including psoriasis, obesity, type 2 diabetes, metabolic syndrome and cardiovascular disease. Chemerin is accepted as being a strong marker because the serum chemerin levels are increased in a CAD condition. However, the chimeric characteristics of chemerin have not been fully investigated. Although chemerin is known to be responsible for CAD development among other factors, authors still investigate it at the marker level. This review focuses on chemerin expression, processing, biological function and relevance to human diseases, and on the role of chemerin in the maintenance of a cardiovascular disease.

Abstract
AIMS The growing prevalence of obesity and its related metabolic disorders in adolescents shows the necessity of urgent focus on the related factors. Adipocytes secretions and their pro- or anti-inflammatory roles play effective roles in adipocytes metabolism. We assessed the relation between adiponectin, chemerin and lipid profile in hit phase of life. METHODS This case-control study conducted on 78 adolescent girls, divided based on BMI percentile. Serum chemerin, adiponectin, lipid profile and body fat mass were measured. Data were analyzed using Pearson correlation test. The interactive relation between these variables was assessed using Structural Equation Modeling (SEM). Data were analyzed using SPSS software and AMOS software. RESULTS Chemerin were correlated significantly with triglyceride (r=0.584 versus r=0.319), HDL-cholestrol (r=-0.323 versus r=-0.335), LDL-cholestrol (r=0.368 versus r=0.327) and fat mass (r=0.372 versus r=0.357) in obese versus non-obese girls; while the mentioned correlation were non-significant with total cholesterol in obese group (r=0.233 versus r=0.336). Furthermore, there were significant association between adiponectin and triglyceride (r=-0.404 versus r=-0.317), HDL-cholesterol (r=0.332 versus r=0.316) and fat mass (r=-0.529 versus r=-0.346) in obese versus non-obese girls, respectively. CONCLUSION There were positive associations between lipid profile components and serum chemerin levels. Adiponectin levels were in positive correlation with HDL-cholesterol concentrations. Chemerin showed positive correlations with potent health threatening components of lipid profile including triglyceride and cholesterol levels in adolescents.

Abstract
OBJECTIVE Chemerin is a novel adipokine that is correlated with adipocyte differentiation, glucose metabolism, and inflammation. We aimed to investigate the relation between serum chemerin level and subclinical atherosclerosis markers as exemplified by brachial artery pulse wave velocity (baPWV), carotid intima-media thickness (CIMT), epicardial fat thickness (EFT), and carotid plaque presence in diabetes and prediabetes. METHODS Age-, body mass index (BMI)-, and gender-matched patients with type 2 DM (n=30), prediabetes (n=25), and normal glucose tolerance (n=25) were included in this cross-sectional study. Serum chemerin level, lipid parameters, glucose metabolism marker, baPWV, CIMT, EFT, and anthropometric were recorded. The independent risk factors for atherosclerosis markers were determined by linear and/or multiple logistic regression analysis. RESULTS baPWV and carotid plaque presence were higher in the diabetes group than in prediabetes and control groups (p=0.039 and p=0.035 respectively), whereas serum chemerin levels were similar among groups (p=0.338). Chemerin levels were not correlated with PWV, CIMT, and epicardial fat thickness overall or in the subgroups. Overall and in the diabetes group, chemerin levels were positively correlated with the key components of metabolic syndrome as BMI, total body fat percentage, waist circumference, triglyceride, and systolic and diastolic blood pressure (BP). After adjusting for age, gender, and BMI, only the association between chemerin and systolic BP remained significant. Chemerin was not found as an independent risk factor for predicting atherosclerosis in diabetes and prediabetes. CONCLUSION Chemerin is not a predictive marker for atherosclerosis in diabetes and prediabetes, but correlates well with key aspects of the metabolic syndrome particularly in diabetes.

Abstract
The novel adipokine chemerin, encoded by the RARRES2 gene, has been suggested to be linked to insulin resistance and to the metabolic syndrome (MetS). However, no well-defined cardiovascular profile has been reported and the association with coronary artery disease (CAD) is a matter of debate. Because there is a relation between renal dysfunction and CAD, we analyzed plasma chemerin levels and the estimated glomerular filtration rate (eGFR) in 495 patients undergoing coronary angiography for the evaluation of established or suspected stable CAD. Chemerin levels were higher in patients with Type 2 diabetes mellitus (T2DM, n=111) and the metabolic syndrome (MetS, n=147) than in subjects without T2DM (191.5±72.9 vs. 169.7±64.7ng/ml, p=0.001) or the MetS (201.2±71.0 vs. 163,1ng/ml, p<0.001), but did not differ significantly between patients with significant CAD (n=247) and those without significant CAD (177.1±67.0 vs. 171.7±67.2ng/ml, p=0.193). Analysis of covariance using age, sex, and BMI as covariates showed that chemerin was significantly and independently associated with eGFR (F=49.6, p<0.001). After an 8-year follow-up period, patients with high chemerin levels were more often affected by cardiovascular events (HR=1.72 [95% CI 1.19-2.47], p=0.004), even after appropriate adjustment for age, gender, BMI, as well as eGFR (adjusted HR 1.51 [95% CI 1.03-2.23], p=0.037). Given the cardiometabolic role of chemerin, we also applied a Cardio-Metabo Chip analysis and revealed a genome-wide significant association with SNPs (rs55709438, rs2444030, and rs3098423) located at chromosomal region 15q15-23, which were associated with metabolic traits and eGFR. This study for the first time demonstrates that high chemerin concentrations are significantly associated with renal impairment and predictive of cardiovascular events and that 15q15-23 might have an impact on chemerin levels beyond common genetic variations in RARRES2.

Endocrine 2015; 48:299-308.

Abstract
The aim of this study was to determine chemerin levels in preeclampsia and to assess the effects of this anti-inflammatory factor on endothelial nitric oxide synthase (eNOS), nuclear factor (NF)-κB, and vascular cell adhesion molecule (VCAM) expression in human umbilical vein endothelial cells (HUVECs). Serum chemerin and eNOS levels were measured by enzyme-linked immunosorbent assays, while chemerin mRNA and protein levels were measured by fluorescent quantitative polymerase chain reaction and Western blotting, respectively. Nitric oxide (NO) concentrations were determined with a colorimetric method. Akt and eNOS phosphorylation were assessed by Western blotting. We also tested the effects of the phosphoinositide 3-kinase inhibitor LY294002 and the eNOS inhibitor L-NAME. NF-κB p65 and VCAM-1 phosphorylation were assessed by Western blotting to investigate the role of chemerin in tumor necrosis factor (TNF)-α-induced HUVEC injury. Serum chemerin levels were increased in preeclampsia, while eNOS was decreased. Chemerin mRNA and protein were both increased in placentae from patients with preeclampsia. Furthermore, chemerin serum level positively correlated with blood pressure, body mass index, and serum insulin and was negatively correlated with serum eNOS. Chemerin dose-dependently increased NO concentrations in supernatants. Chemerin can increase eNOS and Akt levels in HUVECs, and these results could be partly blocked by LY294002 and L-NAME. Chemerin significantly decreased TNF-α-induced NF-κB and VCAM-1 in HUVECs, and these changes were partly inhibited by LY294002 and L-NAME. Chemerin may play a protective role by regulating NO signaling. Future studies should assess the role of chemerin in preeclampsia and other vascular diseases.

Abstract
BACKGROUND Obesity is a low-grade chronic inflammation. This epidemic is growing in different age groups including adolescents. It is accompanied with a decrease in the age for incidence of obesity-related disorders. Chemerin, as a chemokine and stimulator of anti-inflammatory adiponectin, links immune system, adipose tissue and inflammation. It may be useful in predicting obesity in the hit phase of life. This study aims to assess serum chemerin and adiponectin in relation to the inflammation and obesity indices. METHODS This case-control study was conducted on 82 adolescent girls, aged12-18 years. They were categorized based on the percentiles of the body mass index (BMI).Serum chemerin, adiponectin, high-sensitive C-reactive protein (Hs-CRP), body fat mass and its percent, waist circumference (WC) ,hip circumference (HC) were measured; BMI and waist-to-hip ratio (WHR)were calculated. Data were analyzed by independent Student's t-test and Pearson correlation; path analysis was conducted, as well. RESULTS We found a negative significant association between chemerin and adiponectin levels in both obese and non-obese groups(r =-0.387, P = 0.014 vs. r = 0.362, respectively, P = 0.018). Serum chemerin was higher in obese than in non-obese adolescents (441.83 ± 47.79 vs. 409.30 ± 66.12 µg /l, respectively, P = 0.012), whereas mean adiponectin level was lower in obese participants than in the other group (4.79 ± 0.94 versus 5.2 ± 0.53µg/ml, respectively, P = 0.016). Chemerin concentrations had significant positive correlation with Hs-CRP levels, BMI, WC, HC, WHR, body fat mass and its percent (P < 0.05). CONCLUSION Chemerin concentrations were associated with and adiponectin levels in obese girl adolescents, negatively. Hs-CRP, BMI, WC, HC, WHR, body fat mass and its' percent were in positive relation with chemerin levels, and inverse association with serum adiponectin concentrations. Our findings suggest that chemerin can be considered as an early marker of the inflammatory process in obesity.

Abstract
OBJECTIVES The newly identified adipokine chemerin has been shown to be associated with the components of MetS, inflammation and insulin resistance. In this study, the relationship between serum chemerin levels and the presence and severity of coronary artery disease (CAD) was evaluated in patients with MetS. METHODS The study population consisted of 84 MetS patients (43 patients with CAD and 41 without CAD), who had coronary angiography for suspected coronary artery disease, and 46 healthy individuals as a control group. Angiographic CAD was defined as ≥ 50% luminal diameter stenosis of at least one major epicardial coronary artery. The severity of CAD was determined by the Gensini score. Serum chemerin levels were measured with enzyme linked immunosorbent assay (ELISA). RESULTS Serum chemerin levels were significantly higher in patients with MetS (n=84) than those in the control group (120.47±25.32 vs. 90.4±11.4 ng/ml P < 0.001). In addition, MetS patients with CAD had higher chemerin levels than MetS patients without CAD (128.7±26.6 vs. 115.7±15.2 ng/ml, P < 0.001). Serum chemerin levels had a significant positive correlation with the Gensini score (r=0.58, P < 0.001). Multivariate logistic regression demonstrated that serum high-density lipoprotein cholesterol (HDL-C) and chemerin levels were significant and independent predictors for determining the presence of angiographic CAD (OR=1.009, 95% CI: 0.972-1.057; P=0.003 and OR=0.925, 95% CI: 0.896-0.922; P < 0.001, respectively). CONCLUSION This study demonstrated that in patients with MetS, chemerin levels were higher in patients with CAD than patients without CAD and also showed a significant positive correlation with CAD severity.

Abstract
Chemerin is a novel adipokine linked to inflammation. The cross-sectional studies have reported that maternal chemerin serum concentrations are significantly increased in pre-eclampsia. However, limited data are available regarding the cause-effect relationship between chemerin and pre-eclampsia. The aim of this prospective observational study was to evaluate predictive significance of the first-trimester maternal serum chemerin levels for pre-eclampsia and to further confirm the hypothesis that chemerin is an important causative factor in the pathogenesis of pre-eclampsia. 518 pregnancy women were recruited. The first-trimester maternal serum chemerin levels were determined using enzyme-linked immunosorbent assay. The first-trimester maternal serum chemerin levels were statistically significantly elevated in women with pre-eclampsia compared with those without pre-eclampsia and in severe pre-eclampsia women compared with mild pre-eclampsia women. Serum chemerin levels remained positively associated with plasma C-reactive protein levels using a linear regression model. A logistic-regression analysis demonstrated that body mass index and serum chemerin levels appeared to be the independent predictors of pre-eclampsia. A receiver–operating characteristic curve analysis identified that serum chemerin levels predicted pre-eclampsia with high predictive value. The predictive value of the chemerin concentrations was similar to that of body mass index. Chemerin improved the predictive value of body mass index statistically significantly. Thus, our results suggest that high serum chemerin levels are associated with inflammation and pre-eclampsia independently, as well as chemerin may play a role as predictive biomarker for pre-eclampsia and be an important causative factor in the pathogenesis of pre-eclampsia.

Abstract
OBJECTIVES To compare serum chemerin levels between women with classic hyperandrogenic PCOS, euandrogenic PCOS and matched control subjects. RESEARCH DESIGN AND METHODS This study was carried out at the Second XiangYa Hospital between July 2012 and April 2013. Sixty-seven women with PCOS and 20 controls were included. Blood pressure, body mass index (BMI), waist to hip ratio (WHR), fasting insulin, fasting plasma glucose and blood serum hormone and blood lipid were measured. Transvaginal ultrasound was performed. Serum chemerin was measured by ELISA. RESULTS Serum chemerin was significantly higher in classic hyperandrogenic PCOS compared with euandrogenic PCOS and controls (311.07 ± 141.87 ng/mL versus 228.03 ± 119.66 ng/mL and 225.87 ± 86.44 ng/mL, p < 0.05). Serum chemerin was positively related to follicle count, ovarian volume, the level of testosterone, luteinizing hormone/follicle-stimulating hormone, low-density lipoprotein, triglycerides, fasting blood insulin, insulin resistance by homeostasis model assessment, WHR and BMI, while negatively related to the level of high-density lipoprotein. Multiple linear regression analyses revealed ovarian volumes and WHR were the significant influencing factors of chemerin (p < 0.05). The area under the receiver operating characteristic curve for chemerin reached a value of 0.684 (0.572-0.796, 95% confidence interval). The best compromise between sensitivity (80.0%) and specificity (47.6%) was obtained with a cutoff value of 200.94 ng/mL. CONCLUSIONS Serum chemerin level was increased in Chinese women with classic hyperandrogenic PCOS. Serum chemerin measurement offers a relatively moderate diagnostic potency with a sensitivity of 80.0% and a specificity of 47.6% at 200.94 ng/mL. This suggested that chemerin may be involved in the development of the metabolic syndrome of classic PCOS.

Abstract
OBJECTIVE Chemerin is a recently identified adipocytokine that has been positively correlated with the presence and severity of coronary artery disease (CAD). However, no studies have examined circulating chemerin levels as a predictor of acute coronary syndrome (ACS). The purpose of this study is to evaluate whether chemerin levels predict the onset of ACS. MATERIALS/METHODS We studied 90 men whose serum had been collected at least 2 years before the development of ACS, and 162 controls matched with the cases in a 1:2 fashion for age and year of collection. The mean age of the cohort was 66.3±9.6 years (range 34-84 years). Serum chemerin levels were measured with a commercially available enzyme-linked immunosorbent assay. RESULTS Age was positively associated with chemerin levels (r=0.39, p<0.001). Logistic regression analysis, adjusting for years since blood collection, demonstrated a null association between chemerin levels and the odds ratio for development of ACS (OR: 0.99, 95% CI [0.99-1.001]). This association remained null after adjusting for age (OR: 0.99 95% CI [0.99-1.001]). CONCLUSIONS Although cross-sectional and case-control studies suggest a positive association between chemerin levels and CAD, we demonstrate that chemerin levels do not predict the development of ACS.

Chemerin reduces vascular nitric oxide/cGMP signalling in rat aorta: a link to vascular dysfunction in obesity? Clin Sci (Lond) 2014; 127:111-22.

Abstract
The adipokine chemerin has been implicated in cardiovascular complications associated with obesity and the metabolic syndrome. Chemerin has direct effects on the vasculature, augmenting vascular responses to contractile stimuli. As NO/cGMP signalling plays a role in vascular dysfunction associated with obesity and the metabolic syndrome, we hypothesized that chemerin induces vascular dysfunction by decreasing NO/cGMP signalling. Aortic rings from male Wistar rats (10-12 weeks of age) were incubated with chemerin (0.5 or 5 ng/ml for 1 h) or vehicle and isometric tension was recorded. Vasorelaxation in response to ACh (acetylcholine), SNP (sodium nitroprusside) and BAY 412272 [an sGC (soluble guanylate cyclase) stimulator] were decreased in chemerin-treated vessels. The NOS (NO synthase) cofactor BH4 (tetrahydrobiopterin), an O2- (superoxide anion) scavenger (tiron) and a SOD (superoxide dismutase) mimetic (tempol) abolished the effects of chemerin on ACh-induced vasodilation. eNOS (endothelial NOS) phosphorylation, determined by Western blotting, was increased in chemerin-treated vessels; however, the enzyme was mainly in the monomeric form, with decreased eNOS dimer/monomer ratio. Chemerin decreased the mRNA levels of the rate-limiting enzyme for BH4 biosynthesis GTP cyclohydrolase I. Chemerin-incubated vessels displayed decreased NO production, along with increased ROS (reactive oxygen species) generation. These effects were abrogated by BH4, tempol and L-NAME (NG-nitro-L-arginine methyl ester). sGC protein expression and cGMP levels were decreased in chemerin-incubated vessels. These results demonstrate that chemerin reduces NO production, enhances NO breakdown and also decreases NO-dependent cGMP signalling, thereby reducing vascular relaxation. Potential mechanisms mediating the effects of chemerin in the vasculature include eNOS uncoupling, increased O2- generation and reduced GC activity.

Abstract
Objective Coronary artery disease (CAD) is associated with abdominal obesity and metabolic syndrome. Adipocytes secrete adipokines, including the newly discovered adipocyte fatty acid binding protein (A-FABP) and chemerin. Adipokines contribute to the pathogenesis of CAD. In patients with CAD, the presence of significant ischemia predicts adverse outcomes. It is unknown whether adipokines can be better predictors of the presence of significant myocardial ischemia than conventional risk factors. This study aimed to compare adipokines with clinical risk factors and abdominal obesity as predictive factors for significant myocardial ischemia. Methods One hundred and ninety-six adults with suspected, but unproven, CAD were consecutively enrolled. The main measures were clinical and biochemical parameters and stress myocardial perfusion imaging with gated myocardial perfusion single-photon emission computed tomography (SPECT), with computed tomography (CT) attenuation correction. The abdominal visceral fat area was examined using a hybrid SPECT/CT scanner. Serum levels of high-sensitivity C-reactive protein (hs-CRP) and adipokines (adiponectin, A-FABP, and chemerin) were evaluated. Results A-FABP levels correlated significantly with adiponectin, hs-CRP, body mass index, waist circumference, and visceral fat area. A-FABP was significantly associated with metabolic syndrome (OR 3.2, 95% CI 1.6–6.4, p = 0.001), significant myocardial ischemia (OR 1.9, 95% CI 1.0–3.4, p = 0.05), and stress lung-to-heart ratio (β = 0.03, p = 0.03) on SPECT. Chemerin was significantly associated with serum triglyceride levels but not with metabolic syndrome, significant ischemia, or stress lung-to-heart ratio on SPECT. A-FABP was better at detecting significant inducible ischemia than other biomarkers, although this was a modest improvement (area under ROC curve 0.579, 95% CI 0.46–0.69). Conclusions Serum A-FABP concentrations correlate significantly with visceral fat area, metabolic syndrome, and predicted significant myocardial ischemia on SPECT. This may help to more accurately assess CAD risk, especially in patients with metabolic syndrome.

Abstract
BACKGROUND Chemerin is a novel adipokine that plays a role in inflammation and atherosclerosis. Although there are several correlations between hypertension and the inflammatory system, there is still insufficient information about the relationship between blood pressure variability and inflammatory markers. In this study, we aimed to determine whether chemerin levels are elevated in non-dipper patients compared with dippers and healthy controls. MATERIAL AND METHODS This study was composed of a group of 90 patients: 60 hypertensive patients and 30 healthy control subjects (12 males, mean age 53.2 ± 15.4 years). Ambulatory blood pressure monitoring devices (ABPM) were connected to all patients. Using data from the ABPM, hypertensive patients were divided into 2 groups: 30 dipper patients (12 males, mean age 52.5 ± 15.1 years) and 30 non-dipper patients (11 males, mean age 54.6 ± 13.0 years). Complete blood count and biochemistry were measured by standard methods and plasma chemerin concentrations were quantified by ELISA. RESULTS Non-dipper patients demonstrated higher chemerin levels compared to dippers and normotensives (219.7 ± 16.3 vs. 182.4 ± 21.4 ng/ml; 219.7 ± 16.3 vs. 85.4 ± 38.1 ng/ml, respectively, p<0.001 for both comparisons). A receiver operating characteristic curve analysis revealed that the optimal cut-off value for chemerin to predict a non-dipping pattern was 201.4, with 90% sensitivity and 90% specificity. There was a positive correlation between chemerin levels and all ambulatory blood pressure values in all hypertensive patients. CONCLUSIONS Chemerin, which plays a role in inflammation and atherosclerosis, was higher in non-dippers compared to dippers and normotensives. Additionally, chemerin shows positive correlations with blood pressure.

Abstract
Chemerin is an adipocyte-secreted protein with autocrine/paracrine roles on adipose development and function as well as endocrine roles in metabolism and immunity. Following prochemerin secretion, protease-mediated generation of chemerin isoforms with a range of biological activities is a key regulatory mechanism controlling local, context-specific chemerin bioactivity. Together, experimental and clinical data indicate that localized and/or circulating chemerin expression and activation are elevated in numerous metabolic and inflammatory diseases including psoriasis, obesity, type 2 diabetes, metabolic syndrome and cardiovascular disease. These elevations are positively correlated with deleterious changes in glucose, lipid, and cytokine homeostasis, and may serve as a link between obesity, inflammation and other metabolic disorders. This review highlights the current state of knowledge regarding chemerin expression, processing, biological function and relevance to human disease, particularly with respect to adipose tissue development, inflammation, glucose homeostasis and cardiovascular disease. Furthermore, it discusses study variability, deficiencies in current measurement, and questions concerning chemerin function in disease, with a special emphasis on techniques and tools used to properly assess chemerin biology. An integration of basic and clinical research is key to understanding how chemerin influences disease pathobiology, and whether modulation of chemerin levels and/or activity may serve as a potential method to prevent and treat metabolic diseases.

Abstract
Chemerin is a novel protein linked to adipocyte differentiation and the development of metabolic imbalances. We sought to examine the relationship of chemerin with metabolic syndrome disturbances including body fat percentage, serum lipid, glucose, insulin levels and body fat percentage in lean and obese volunteers. A cross-sectional study of 90 randomly selected healthy males from Pakistan were divided into three groups as per Body Mass Index (BMI) criteria for South Asian Population. Anthropometric measurements were taken for BMI, waist circumference, hip circumference and body fat percentage, while serum analyses were performed for fasting blood glucose, fasting insulin, fasting lipid profile and serum chemerin. Associations between serum chemerin levels and body fat and other metabolic syndrome parameters were performed using ANOVA and multiple regression analyses. Data was presented as Mean±SD. In all statistical analyses p-values <0.05 were considered significant. Circulating chemerin levels were significantly higher in obese subjects with BMI greater than 25 kg/m2 compared with those with a BMI below 25 kg/m2 (P = 0.001). Serum chemerin levels were found to be independently and significantly associated with serum levels of cholesterol (P = 0.0160; r = 0.255), fasting glucose (P = 0.002; r = 0.323), HOMA-IR (P = 0.004; r = 0.300) and hip circumference (P = 0.021; r = 0.246). This demonstrates that chemerin levels are associated with obesity and dyslipidemia and may play a role in the development of insulin resistance. This data suggests that chemerin may serve as an independent marker in diagnosing these conditions even before they become clinically symptomatic.

Abstract
Chemerin is a leukocyte chemoattractant and adipokine with important immune and metabolic roles. Chemerin, secreted in an inactive form prochemerin, undergoes C-terminal proteolytic cleavage to generate active chemerin, a ligand for the chemokine-like receptor-1 (CMKLR1). We previously identified that adipocytes secrete and activate chemerin. Following treatment with the obesity-associated inflammatory mediator TNFα, unknown adipocyte mechanisms are altered resulting in an increased ratio of active to total chemerin production. Based on these findings we hypothesized adipocytes produce proteases capable of modifying chemerin and its ability to activate CMKRL1. 3T3-L1 adipocytes expressed mRNA of immunocyte and fibrinolytic proteases known to activate chemerin in vitro. Following treatment with a general protease inhibitor cocktail (PIC), the TNFα-stimulated increase in apparent active chemerin concentration in adipocyte media was amplified 10-fold, as measured by CMKLR1 activation. When the components of the PIC were investigated individually, aprotinin, a serine protease inhibitor, blocked 90% of the TNFα-associated increase in active chemerin. The serine proteases, elastase and tryptase were elevated in adipocyte media following treatment with TNFα and their targeted neutralization recapitulated the aprotinin-mediated effects. In contrast, bestatin, an aminopeptidase inhibitor, further elevated the TNFα-associated increase in active chemerin. Our results support that adipocytes regulate chemerin by serine protease-mediated activation pathways and aminopeptidase deactivation pathways. Following TNFα treatment, increased elastase and tryptase modify the balance between activation and deactivation, elevating active chemerin concentration in adipocyte media and subsequent CMKLR1 activation.

Abstract
Obesity and type 2 diabetes have reached epidemic levels and account for a substantial portion of the annual health expenditures of developed nations. While there is an abundance of epidemiological evidence demonstrating that obesity is a primary risk factor for developing type 2 diabetes, the mechanism(s) underlying this linkage are not completely understood. Given the enormous impact of these disorders on global health, considerable research effort has been devoted to elucidate the pathophysiological relationship between these two disorders. Two factors believed to contribute to the causal link between obesity and type 2 diabetes are chronic inflammation and altered secretion of adipose-derived signaling molecules (adipokines). Independent lines of investigation have implicated the novel adipokine chemerin as a regulator of adipogenesis, inflammation, and glucose metabolism through interactions with the cognate cell surface receptor chemokine-like receptor 1. Increased levels of chemerin that occur with obesity are hypothesized to be a causal factor in the development of type 2 diabetes as a consequence of dysregulation of the key physiological processes regulated by this adipokine. This review summarizes current research on the biological roles of chemerin and chemokine-like receptor 1, and highlights key questions to guide future research on the role of this adipokine in mediating obesity and the development of type 2 diabetes.

Potential association between coronary artery disease and the inflammatory biomarker YKL-40 in asymptomatic patients with type 2 diabetes mellitus. Cardiovasc Diabetol 2012; 11:84.

Abstract
Background Inflammation plays an important role in coronary artery disease from the initiation of endothelial dysfunction to plaque formation to final rupture of the plaque. In this study, we investigated the potential pathophysiological and clinical relevance of novel cytokines secreted from various cells including adipocytes, endothelial cells, and inflammatory cells, in predicting coronary artery disease (CAD) in asymptomatic subjects with type 2 diabetes mellitus. Methods We enrolled a total of 70 asymptomatic type 2 diabetic patients without a documented history of cardiovascular disease, and determined serum levels of chemerin, omentin-1, YKL-40, and sCD26. We performed coronary computed tomographic angiography (cCTA) in all subjects, and defined coronary artery stenosis ≥ 50 % as significant CAD in this study. Results Subjects were classified into two groups: patients with suspected coronary artery stenosis on cCTA (group I, n = 41) and patients without any evidence of stenosis on cCTA (group II, n = 29). Group I showed significantly higher YLK-40 levels and lower HDL-C levels than group II (p = 0.038, 0.036, respectively). Levels of chemerin, omentin-1, and sCD26 were not significantly different between the two groups. Serum YKL-40 levels were positively correlated with systolic/diastolic BP, fasting/postprandial triglyceride levels, and Framingham risk score. Furthermore, YKL-40 levels showed moderate correlation with the degree of coronary artery stenosis and the coronary artery calcium score determined from cCTA. In multivariate logistic analysis, after adjusting for age, gender, smoking history, hypertension, and LDL-cholesterol, YLK-40 levels showed only borderline significance. Conclusions YKL-40, which is secreted primarily from inflammatory cells, was associated with several CVD risk factors and was elevated in type 2 diabetic patients with suspected coronary artery stensosis on cCTA. These results suggest the possibility that the inflammatory biomarker YKL-40 might be associated with coronary artery disease in asymptomatic patients with type 2 diabetes mellitus.

Abstract
Chemerin is a newly discovered adipokine which has been found closely associated with obesity, metabolic syndrome (MetS), and inflammatory status. This study will investigate whether serum chemerin levels are associated with coronary artery disease (CAD) independently of other cardiovascular risk factors. This study included a total of 430 subjects (239 with CAD and 191 with non-CAD) who underwent coronary angiography. Anthropometric measurements were performed and chemerin, glucose, lipid profiles, and other biochemical characteristics were measured. The severity of coronary atherosclerosis was estimated by the total number of diseased vessels and Gensini score. Serum chemerin levels were significantly higher in the CAD group than in the non-CAD group (P = 0.011). The odds ratios (95% CI) of CAD across increasing quartiles of serum chemerin were 1.04 (0.61-1.78), 1.08 (0.63-1.83), and 1.87 (1.07-3.24), (P = 0.386, 0.508, and 0.012, respectively). Adjusting for age, sex, and other conventional risk factors for CAD did not appreciably alter the results. Serum chemerin levels were significantly increased with an increasing of number of diseased vessels (P = 0.024). In conditional linear regression models, chemerin levels were positively related to Gensini score even after established cardiovascular risk factors (β = 0.13, P = 0.019). Correlation analysis showed serum chemerin levels were significantly associated with TG levels, TC levels, fasting serum insulin, HOMA-IR and MetS (all P < 0.05). Higher serum chemerin levels were associated with increased risk of CAD and metabolic parameters in Chinese adults. Chemerin may represent a novel link between metabolic signals and atherosclerosis.

Abstract
The prevalence of diabetes in Korea has increased six- to sevenfold over the past 40 years with its complications becoming major causes of morbidity and mortality. The rate of death among patients with diabetes is about twice as high as that among persons without diabetes and the most common cause of death is cardiovascular disease (30.6%). Despite the seriousness of diabetic complications, 30 to 70% of patients receive inadequate care, and only 40% of treated diabetic patients achieve the optimal control with HbA1c level <7% in Korea. In 2006, over 30 to 40% of patients with diabetes have microvascular complications and around 10% of them have macrovascular complications from our national data. Despite there are some debates about intensive glycemic control resulting in the deterioration of macrovascular complication, multifactorial treatment approaches including proper glycemic control are important to prevent diabetic complications. There have been needs for finding proper biomarkers for predicting diabetic complications properly but we still need more longitudinal studies to find this correlation with causal relationship. In this article, we wanted to review the recent status of micro- and macrovascular complications of type 2 diabetes in Korea from integration of many epidemiologic studies.
