Poult Sci 2024; 103:103927. [PMID: 38917607 PMCID: PMC11255896 DOI: 10.1016/j.psj.2024.103927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 03/01/2024] [Accepted: 05/29/2024] [Indexed: 06/27/2024] Open
Abstract
Goose creates important economic value depending on their enrich nutrients of meat. Our previous study investigates potential candidate genes associated with variations in meat quality between Xianghai Flying (XHF) Goose and Zi Goose through genomic and transcriptome integrated analysis. Screening of 5 differential expression candidate genes related to muscle development identified by the FST, XP-EHH and RNA-seq in breast muscle from various geese. Among them, C1QTNF1 (C1q and TNF related protein 1), a gene of unknown function in goose, which observed mutations in coding sequence regions in sequencing data. Its function was explored after overexpression and knockdown which designed depending on the genetic sequence of the goose, respectively. Results showed that over-expression of C1QTNF1 significantly enhances cell proliferation and viability. In addition, the expression levels of the fusion marker gene Myomaker and the differentiation marker gene MyoD are significantly upregulated in cells. Knock-down C1QTNF1 leads to down regulated Myomaker and MyoD which involved muscle formation. But, the expression level of muscle atrophy marker MuRF is not significantly changed among different transfection groups. Since protein structures and interactions are closely related to their functions, we further analyzed the C1QTNF1 for physicochemical properties, structural predictions, protein interactions and homology. It can be reasonably inferred that C1QTNF1 has a similar effect to collagen, which may affect muscle development. In summary, we first speculate that C1QTNF1 may play an important regulatory role in muscle growth and development and thereby contributes to the further understanding of the genetic mechanisms that underlie meat quality traits of goose.

Abstract
PURPOSE To investigate the effect of azilsartan on myocardial remodeling after acute myocardial infarction (AMI). METHODS A total of 200 AMI patients under percutaneous coronary intervention (PCI) were selected from the Affiliated Huaian No.1 People's Hospital of Nanjing Medical University from Jan 2021 to Dec 2021. The subjects were randomly divided to take either azilsartan or benazepril. Serum C1q tumor necrosis factor-associated protein 1 (CTRP1) levels were detected in all subjects after admission, and the indices of left ventricular end-diastolic volume (LVEDV), left ventricular end-diastolic diameter (LVEDD), and left ventricular ejection fraction (LVEF) were measured by using echocardiography. At the follow-up of 6 months and 1 year after PCI, the differences in CTRP1 and echocardiogram indices between the two groups were compared, and the influencing factors of myocardial remodeling after acute myocardial infarction were analyzed. RESULTS The levels of LVEDV and CTRP1 in all subjects at 6 months and 1 year after PCI were lower than those before discharge, and the LVEDV in the azilsartan group at 6 months and 1 year after PCI was lower than that in the benazepril group. An improvement in myocardial remodeling was obviously observed within 6 months after PCI, but the effect declined over time. CONCLUSIONS Azilsartan can improve myocardial remodeling after acute myocardial infarction. CTRP1 may become an effective target for the prevention and treatment of myocardial remodeling after acute myocardial infarction.

Int J Mol Sci 2023; 24:ijms24076839. [PMID: 37047812 PMCID: PMC10095411 DOI: 10.3390/ijms24076839] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 03/21/2023] [Accepted: 03/31/2023] [Indexed: 04/14/2023] Open
Abstract
Inadequate wound healing of ocular surface injuries can lead to permanent visual impairment. The relaxin ligand-receptor system has been demonstrated to promote corneal wound healing through increased cell migration and modulation of extracellular matrix formation. Recently, C1q/tumor necrosis factor-related protein (CTRP) 8 was identified as a novel interaction partner of relaxin receptor RXFP1. Additional data also suggest a role for CTRP1 and CTRP6 in RXFP1-mediated cAMP signaling. However, the role of CTRP1, CTRP6 and CTRP8 at the ocular surface remains unclear. In this study, we investigated the effects of CTRP1, CTRP6, and CTRP8 on epithelial ocular surface wound closure and their dependence on the RXFP1 receptor pathway. CTRP1, CTRP6, and CTRP8 expression was analyzed by RT-PCR and immunohistochemistry in human tissues and cell lines derived from the ocular surface and lacrimal apparatus. In vitro ocular surface wound modeling was performed using scratch assays. We analyzed the effects of recombinant CTRP1, CTRP6, and CTRP8 on cell proliferation and migration in human corneal and conjunctival epithelial cell lines. Dependence on RXFP1 signaling was established by inhibiting ligand binding to RXFP1 using a specific anti-RXFP1 antibody. We detected the expression of CTRP1, CTRP6, and CTRP8 in human tissue samples of the cornea, conjunctiva, meibomian gland, efferent tear ducts, and lacrimal gland, as well as in human corneal, conjunctival, and meibomian gland epithelial cell lines. Scratch assays revealed a dose-dependent increase in the closure rate of surface defects in human corneal epithelial cells after treatment with CTRP1, CTRP6, and CTRP8, but not in conjunctival epithelial cells. Inhibition of RXFP1 fully attenuated the effect of CTRP8 on the closure rate of surface defects in human corneal epithelial cells, whereas the CTRP1 and CTRP6 effects were not completely suppressed. Conclusions: Our findings demonstrate a novel role for CTRP1, CTRP6, and CTRP8 in corneal epithelial wound closure and suggest an involvement of the relaxin receptor RXFP1 signaling pathway. This could be a first step toward new approaches for pharmacological and therapeutic intervention.

Abstract
C1q/tumor necrosis factor (TNF) related proteins (CTRPs) is a newly discovered adipokine family with conservative structure and ubiquitous distribution and is secreted by adipose tissues. Recently, CTRPs have attracted increasing attention due to the its wide-ranging effects upon inflammation and metabolism. To-date, 15 members of CTRPs (CTRP1-15) with the characteristic C1q domain have been characterized. Earlier in-depth phenotypic analyses of mouse models of CTRPs deficiency have also unveiled ample function of CTRPs in inflammation and metabolism. This review focuses on the rise of CTRPs, with a special emphasis on the latest discoveries with regards to the effects of the CTRP family on inflammation and metabolism as well as related diseases. We first introduced the structure of characteristic domain and polymerization of CTRPs to reveal its pleiotropic biological functions. Next, intimate association of CTRP family with inflammation and metabolism, as well as the involvement of CTRPs as nodes in complex molecular networks, were elaborated. With expanding membership of CTRP family, the information presented here provides new perspectives for therapeutic strategies to improve inflammatory and metabolic abnormalities.

Abstract
Cardiovascular diseases (CVDs) are a series of diseases induced by inflammation and lipid metabolism disorders, among others. Metabolic diseases can cause inflammation and abnormal lipid metabolism. C1q/TNF-related proteins 1 (CTRP1) is a paralog of adiponectin that belongs to the CTRP subfamily. CTRP1 is expressed and secreted in adipocytes, macrophages, cardiomyocytes, and other cells. It promotes lipid and glucose metabolism but has bidirectional effects on the regulation of inflammation. Inflammation can also inversely stimulate CTRP1 production. A vicious circle may exist between the two. This article introduces CTRP1 from the structure, expression, and different roles of CTRP1 in CVDs and metabolic diseases, to summarize the role of CTRP1 pleiotropy. Moreover, the proteins which may interact with CTRP1 are predicted through GeneCards and STRING, speculating their effects, to provide new ideas for the study of CTRP1.

Abstract
Aerobic exercise is an effective therapeutic strategy to manage metabolic disorders. However, the mechanisms of aerobic exercise-induced improvements in metabolic diseases are not completely understood. Complement C1q/tumor necrosis factor-related protein (CTRP) 1, CTRP3, CTRP5, and CTRP9 have important roles in improving metabolic disorders via the adenosine monophosphate-activated protein kinase signaling pathway. In this study, we investigated the effects of acute aerobic exercise on circulating CTRP1, CTRP3, CTRP5, and CTRP9 levels in human participants. Eight healthy males with an age of 20.4 ± 0.2 years, height 173.1 ± 1.7 cm, body mass 68.0 ± 1.8 kg, body mass index 22.7 ± 0.7 kg/m2, and maximal oxygen uptake (VO2max) 51.3 ± 2.5 mL/kg/min performed acute aerobic cycling exercise at 75 % of their VO2max for 30 min (data are mean ± standard error). Blood samples were obtained before; immediately after; and 30, 60, and 120 min after exercising. Serum concentrations of CTRP1, CTRP3, CTRP5, CTRP9, tumor necrosis factor-α (TNF-α), and insulin were measured. The CTRP1 concentration significantly increased immediately after exercising and remained elevated for up to 120 min (p < 0.01). The CTRP3 concentration significantly increased at 60 min after exercise (p < 0.05), and the increasing trend continued until at least 120 min after exercise (p < 0.01). The CTRP5, CTRP9, TNF-α, and insulin concentrations significantly increased immediately after exercise (p < 0.05, p < 0.01, p < 0.05, and p < 0.05, respectively) and decreased thereafter. A significant correlation was observed between the peak post-exercise concentrations of CTRP1 and TNF-α (p < 0.05); however, no correlation was observed between the peak post-exercise concentrations of CTRP3 and insulin. The results of this study indicate that acute aerobic exercise may enhance the secretion of CTRP1, CTRP3, CTRP5, and CTRP9 in healthy adults.

Abstract
BACKGROUND C1q/tumor necrosis factor-related protein 1 (CTRP1) is an adipokine secreted by adipose tissue, related to chondrocyte proliferation, inflammation, and glucose homeostasis. However, the therapeutic effects on metabolic disorders and the underlying mechanism were unclear. Here, we investigated the functions and mechanisms of CTRP1 in treating obesity and diabetes. METHODS The plasmid containing human CTRP1 was delivered to mice by hydrodynamic injection, which sustained expression of CTRP1 in the liver and high protein level in the blood. High-fat diet (HFD) fed mice and STZ-induced diabetes model were used to study the effects of CTRP1 on obesity, glucose homeostasis, insulin resistance, and hepatic lipid accumulation. The lipid accumulation in liver and adipose tissue, glucose tolerance, insulin sensitivity, food intake, and energy expenditure were detected by H&E staining, Oil-Red O staining, glucose tolerance test, insulin tolerance test, and metabolic cage, respectively. The metabolic-related genes and signal pathways were determined using qPCR and western blotting. RESULTS With high blood circulation, CTRP1 prevented obesity, hyperglycemia, insulin resistance, and fatty liver in HFD-fed mice. CTRP1 also improved glucose metabolism and insulin resistance in obese and STZ-induced diabetic mice. The metabolic cage study revealed that CTRP1 reduced food intake and enhanced energy expenditure. The mechanistic study demonstrated that CTRP1 upregulated the protein level of leptin in blood, thermogenic gene expression in brown adipose tissue, and the gene expression responsible for lipolysis and glycolysis in white adipose tissue (WAT). CTRP1 also downregulated the expression of inflammatory genes in WAT. Overexpression of CTRP1 activated AMPK and PI3K/Akt signaling pathways and inhibited ERK signaling pathway. CONCLUSION These results demonstrate that CTRP1 could improve glucose homeostasis and prevent HFD-induced obesity and fatty liver through upregulating the energy expenditure and reducing food intake, suggesting CTRP1 may serve as a promising target for treating metabolic diseases.

Abstract
Simple Summary CTRP1 belongs to the C1q and TNF-related protein family, and we generated CTRP1 knockout cells to examine the role of CTRP1 in tumor progression. CTRP1 knockout attenuates cell growth, invasion and tumor growth in mice, suggesting that CTRP1 expression promotes tumor progression. Abstract C1q and TNF-related 1 (C1QTNF1/CTRP1) is an adiponectin-associated protein belonging to the C1q/TNF-related protein family. Recent studies have shown that the C1q and TNF-related protein (CTRP) family is involved in cancer progression; however, the specific role of CTRP1 in tumor progression has not yet been elucidated. To examine the role of CTRP1 in tumor progression, we generated CTRP1 knockout A549 and HCT116 cell lines, which reduced the expression levels of nuclear factor (NF)-κB-dependent and metastasis-promoting transcripts. We demonstrated that CTRP1 knockout inhibited the cell proliferation and invasion and tumor growth. Finally, database analysis showed that CTRP1 expression was upregulated in metastatic cancers and elevated levels of CTRP1 were associated with poor prognosis. These results suggest that CTRP1 expression contributes to NF-κB signaling and promotes tumor progression.

METHODS This cross-sectional study included 202 subjects categorized into MetS and No-MetS according to Harmonizing Adult Treatment Panel III. RESULTS Subjects with MetS showed higher levels of proinflammatory molecules but significantly lower adiponectin levels than subjects with No-MetS. Among the studied adipocytokines, plasminogen activator inhibitor-1 (PAI-1) and adiponectin showed the strongest associations with most MetS components. PAI-1 was associated with MetS (odds ratio (OR) 1.107 (1.065-1.151), P < 0.0001), whereas adiponectin was inversely associated with MetS (OR 0.710 (0.610-0.825), P < 0.0001). Following adjustment by sex, age, body mass index, and 24-hour urinary sodium excretion in a multivariate analysis, the association of PAI-1 (OR 1.090 (1.044-1.137), P < 0.0001) and adiponectin (OR 0.634 (0.519-0.775), P < 0.0001) with MetS remained significant. Multivariate analyses supported a model in which systolic blood pressure (BP) could be predicted by PAI-1, hs-CRP, and matrix metalloproteinase 2 (R2 = 0.125; P = 0.04); diastolic BP (R2 = 0.218; P = 0.0001) and glucose (R2 = 0.074; P = 0.0001) could be predicted by PAI-1; waist circumference could be predicted by PAI-1 and hs-CRP (R2 = 0.28; P = 0.016). Receiver operating characteristic curve analysis showed that a PAI-1 concentration had the best sensitivity and specificity for discriminating subjects with MetS. CONCLUSION PAI-1 and adiponectin rendered the most robust associations with MetS components in a general population, indicating that unfavorable adipose tissue performance is a key contributor to these metabolic anomalies. Further prospective analyses should allow establishing whether these adipocytokines can anticipate the progress of MetS and cardiovascular risk.

Abstract
Human aging is a complex phenomenon characterized by a wide spectrum of biological changes which impact on behavioral and social aspects. Age-related changes are accompanied by a decline in biological function and increased vulnerability leading to frailty, thereby advanced age is identified among the major risk factors of the main chronic human diseases. Aging is characterized by a state of chronic low-grade inflammation, also referred as inflammaging. It recognizes a multifactorial pathogenesis with a prominent role of the innate immune system activation, resulting in tissue degeneration and contributing to adverse outcomes. It is widely recognized that inflammation plays a central role in the development and progression of numerous chronic and cardiovascular diseases. In particular, low-grade inflammation, through an increased risk of atherosclerosis and insulin resistance, promote cardiovascular diseases in the elderly. Low-grade inflammation is also promoted by visceral adiposity, whose accumulation is paralleled by an increased inflammatory status. Aging is associated to increase in epicardial adipose tissue (EAT), the visceral fat depot of the heart. Structural and functional changes in EAT have been shown to be associated with several heart diseases, including coronary artery disease, aortic stenosis, atrial fibrillation, and heart failure. EAT increase is associated with a greater production and secretion of pro-inflammatory mediators and neuro-hormones, so that thickened EAT can pathologically influence, in a paracrine and vasocrine manner, the structure and function of the heart and is associated to a worse cardiovascular outcome. In this review, we will discuss the evidence underlying the interplay between inflammaging, EAT accumulation and cardiovascular diseases. We will examine and discuss the importance of EAT quantification, its characteristics and changes with age and its clinical implication.

Abstract
INTRODUCTION Autism spectrum disorders (ASDs) are neurodevelopmental diseases characterized by communication inabilities, social interaction impairment, repetitive behavior, as well as learning problems. Although the exact mechanism underlying this disease is still obscure, researchers believe that several factors play a significant role in its development and pathogenesis. Some authors have reported an association between adipokines family and autism. C1q/TNF-related protein-1 (CTRP1) is a member of the adipokines family, and we hypothesized that this adipokine might have an influential role in the pathogenesis of ASDs. Since there is no specific marker for screening the disease, we evaluated CTRP1 as a potential marker for achieving this purpose. METHODS Blood samples were collected from 82 (41 ASDs boys, 41 healthy boys as controls) children aged 5-7 years old. CTRP1 gene expression and CTRP1 serum level were measured by quantitative realtime-PCR and enzyme-linked immunosorbent assay methods, respectively. RESULTS It was found that CTRP1 is significantly elevated in autistic children in comparison to healthy controls, both at the gene expression level, as well as at the serum level; demonstrating a good diagnostic value with a good range of sensitivity and specificity for detecting ASDs. CONCLUSION CTRP1 expression is elevated in ASDs boys aged 5-7 years old, suggesting a role for this adipokine in ASDs pathophysiology. Also, receiver operating characteristic curve analyses revealed that this adipokine could be utilized as a diagnostic biomarker for differentiating ASDs patients from healthy individuals along with other recently proposed biomarkers.

Abstract
ABSTRACT Atherosclerosis serves as the pathological basis of most cardiovascular and cerebrovascular diseases. C1q tumor necrosis factor-related protein (CTRP1) is a 35-kDa glycoprotein synthesized by various tissues and cells, such as adipose tissue and macrophages. As an adiponectin paralog, CTRP1 signals through adiponectin receptor 1 (AdipoR1) and participates in a variety of pathophysiological processes. Circulating CTRP1 levels are significantly increased in patients with coronary artery disease. Importantly, CTRP1 was shown to accelerate the development of atherosclerosis by promoting vascular inflammation, macrophage foam cell formation and endothelial barrier dysfunction. This review focused on recent advances regarding the role of CTRP1 in atherogenesis with an emphasis on its potential as a novel biomarker and a promising therapeutic target for atherosclerosis-related diseases.

Abstract
Cerebral ischemic stroke is one of the leading causes of death worldwide. Previous studies have shown that circulating levels of CTRP1 are upregulated in patients with acute ischemic stroke. However, the function of CTRP1 in neurons remains unclear. The purpose of this study was to explore the role of CTRP1 in cerebral ischemia reperfusion injury (CIRI) and to elucidate the underlying mechanism. Middle cerebral artery occlusion/reperfusion (MCAO/R) and oxygen-glucose deprivation/reoxygenation (OGD/R) models were used to simulate cerebral ischemic stroke in vivo and in vitro, respectively. CTRP1 overexpression lentivirus and CTRP1 siRNA were used to observe the effect of CTRP1 expression, and the PERK selective activator CCT020312 was used to activate the PERK signaling pathway. We found the decreased expression of CTRP1 in the cortex of MCAO/R-treated rats and OGD/R-treated primary cortical neurons. CTRP1 overexpression attenuated CIRI, accompanied by the reduction of apoptosis and suppression of the PERK signaling pathway. Interference with CTRP1 expression in vitro aggravated apoptotic activity and increased the expression of proteins involved in the PERK signaling pathway. Moreover, activating the PERK signaling pathway abolished the protective effects of CTRP1 on neuron injury induced by CIRI in vivo and in vitro. In conclusion, CTRP1 protects against CIRI by reducing apoptosis and endoplasmic reticulum stress (ERS) through inhibiting the PERK-dependent signaling pathway, suggesting that CTRP1 plays a crucial role in the pathogenesis of CIRI.

Elevated Levels of CTRP1 in Obesity Contribute to Tumor Progression in a p53-Dependent Manner. Cancers (Basel) 2021; 13:cancers13143619.

Abstract
Simple Summary Obesity is regarded as a risk factor for various cancers. However, the molecular mechanisms linking obesity with cancer remain primarily uncharacterized. In this study, we demonstrate that CTRP1, an adiponectin paralogue, promotes tumor growth in a p53-dependent manner. Obese mice on a high-fat diet showed a higher level of CTRP1 protein in serum. It is also known that CTRP1 treatment contributes to tumor growth and cell migration. These results indicate that an elevated level of CTRP1 in obesity promotes tumor progression. Abstract Mounting evidence supports the relationship between obesity and cancer. However, the molecular mechanisms linking obesity with cancer remain largely uninvestigated. In this study, we demonstrate that the expression of C1q/TNF-related protein 1 (CTRP1), an adiponectin paralogue, contributes to tumor growth by regulating the tumor suppressor p53. In our study, obese mice on a high-fat diet showed higher serum CTRP1 levels. Through in vitro experiments, we showed that the secreted form of CTRP1 in the culture medium decreased p53 expression and p53-dependent transcription in the cells. Moreover, CTRP1 treatment enhanced colony formation and cell migration. These results collectively suggest that elevated levels of CTRP1 in obesity significantly contribute to tumor progression.

Abstract
Obesity and type 2 diabetes are rapidly increasing in the adolescent population. We sought to determine whether adipokines, specifically leptin, C1q/TNF-related proteins 1 (CTRP1) and CTRP9, and the hepatokine fibroblast growth factor 21 (FGF21), are associated with obesity and hyperglycemia in a cohort of lean and obese adolescents, across the spectrum of glycemia. In an observational, longitudinal study of lean and obese adolescents, we measured fasting laboratory tests, oral glucose tolerance tests, and adipokines including leptin, CTRP1, CTRP9, and FGF21. Participants completed baseline and 2-year follow-up study visits and were categorized as lean (LC, lean control; n = 30), obese normoglycemic (ONG; n = 61), and obese hyperglycemic (OHG; n = 31) adolescents at baseline and lean (n = 8), ONG (n = 18), and OHG (n = 4) at follow-up. Groups were compared using ANOVA and regression analysis, and linear mixed effects modeling was used to test for differences in adipokine levels across baseline and follow-up visits. Results showed that at baseline, leptin was higher in all obese groups (P < 0.001) compared with LC. FGF21 was higher in OHG participants compared with LC (P < 0.001) and ONG (P < 0.001) and positively associated with fasting glucose (P < 0.001), fasting insulin (P < 0.001), Homeostasis Model Assessment-Insulin Resistance Index (HOMA-IR; P < 0.001), and hemoglobin A1c (HbA1c; P = 0.01). CTRP1 was higher in OHG compared with ONG (P = 0.03). CTRP9 was not associated with obesity or hyperglycemia in this pediatric cohort. At 2 years, leptin decreased in ONG (P = 0.003) and FGF21 increased in OHG (P = 0.02), relative to lean controls. Altered adipokine levels are associated with the inflammatory milieu in obese youth with and without hyperglycemia. In adolescence, the novel adipokine CTRP1 was elevated with hyperglycemia, whereas CTRP9 was unchanged in this cohort.NEW & NOTEWORTHY Leptin is higher in obese adolescents and FGF21 is higher in obese hyperglycemic adolescents. The novel adipokine CTRP1 is higher in obese hyperglycemic adolescents, whereas CTRP9 was unchanged in this adolescent cohort.

Abstract
C1q/TNF-related protein 1 (CTRP1) is an endocrine factor with metabolic, cardiovascular, and renal functions. We previously showed that aged Ctrp1-knockout (KO) mice fed a control low-fat diet develop renal hypertrophy and dysfunction. Since aging and obesity adversely affect various organ systems, we hypothesized that aging, in combination with obesity induced by chronic high-fat feeding, would further exacerbate renal dysfunction in CTRP1-deficient animals. To test this, we fed wild-type and Ctrp1-KO mice a high-fat diet for 8 mo or longer. Contrary to our expectation, no differences were observed in blood pressure, heart function, or vascular stiffness between genotypes. Loss of CTRP1, however, resulted in an approximately twofold renal enlargement (relative to body weight), ∼60% increase in urinary total protein content, and elevated pH, and changes in renal gene expression affecting metabolism, signaling, transcription, cell adhesion, solute and metabolite transport, and inflammation. Assessment of glomerular integrity, the extent of podocyte foot process effacement, as well as renal response to water restriction and salt loading did not reveal significant differences between genotypes. Interestingly, blood platelet, white blood cell, neutrophil, lymphocyte, and eosinophil counts were significantly elevated, whereas mean corpuscular volume and hemoglobin were reduced in Ctrp1-KO mice. Cytokine profiling revealed increased circulating levels of CCL17 and TIMP-1 in KO mice. Compared with our previous study, current data suggest that chronic high-fat feeding affects renal phenotypes differently than similarly aged mice fed a control low-fat diet, highlighting a diet-dependent contribution of CTRP1 deficiency to age-related changes in renal structure and function.

Abstract
Metabolic inflexibility, defined as the inability to respond or adapt to metabolic demand, is now recognised as a driving factor behind many pathologies associated with obesity and the metabolic syndrome. Adipose tissue plays a pivotal role in the ability of an organism to sense, adapt to and counteract environmental changes. It provides a buffer in times of nutrient excess, a fuel reserve during starvation and the ability to resist cold-stress through non-shivering thermogenesis. Recent advances in single-cell RNA sequencing combined with lineage tracing, transcriptomic and proteomic analyses have identified novel adipocyte progenitors that give rise to specialised adipocytes with diverse functions, some of which have the potential to be exploited therapeutically. This review will highlight the common and distinct functions of well-known adipocyte populations with respect to their lineage and plasticity, as well as introducing the most recent members of the adipocyte family and their roles in whole organism energy homeostasis. Finally, this article will outline some of the more preliminary findings from large data sets generated by single-cell transcriptomics of mouse and human adipose tissue and their implications for the field, both for discovery and for therapy.

This study explored whether those with subjective sleepiness have increased plasma tumour necrosis factor-related protein 1 (C1qTNF1), a novel adipose-derived hormone (adipokine), and 24-h ambulatory blood pressure (ABP) compared to those without sleepiness in newly diagnosed, treatment-naïve participants with obstructive sleep apnoea. Methods Overall, 94 participants were included in the analysis. Participants completed the Epworth Sleepiness Scale (ESS), 24-h ABP was monitored, and plasma C1qTNF1 was measured. Sleepy participants were defined as ESS≥10 and nonsleepy as ESS<10. Multiple linear regression was used to explore differences in C1qTNF1, and 24-h mean arterial pressure (MAP) between sleepy and nonsleepy participants, adjusting for age, sex, body mass index, apnoea–hypopnoea index, and smoking status. Results C1qTNF1 was significantly higher in sleepy participants (n=57) compared to nonsleepy participants (n=37) (β=0.41 NPX, 95% CI 0.02, 0.80; p=0.04). The 24-h MAP was significantly higher in sleepy participants compared to nonsleepy participants (β=4.06 mmHg, 95% CI 0.36, 7.77; p=0.03). Conclusions Our findings show that sleepiness is associated with inflammation and higher 24-h MAP in sleep apnoea. Excessive sleepiness experienced by treatment-naïve patients with obstructive sleep apnoea is associated with inflammation, higher daily systolic ambulatory blood pressure and higher 24 h mean arterial pressurehttps://bit.ly/3goeqGD

Abstract
The present review aimed to present the research highlights on C1q/TNF-related protein 1 (CTRP1), a member of the recently discovered family of highly conserved adiponectin paralog proteins, C1q tumor necrosis factor-related proteins. CTRP1 plays an important role in regulating body energy homeostasis and sensitivity to insulin. Studies on animal models have shown that it lowers the concentration of glucose. Elevated concentrations of CTRP1 reduce weight gain and diet-induced insulin resistance. CTRP1 limits the extent of ischemia-reperfusion injury in acute myocardial infarction. It inhibits platelet aggregation by blocking von Willebrand factor binding to collagen. In patients with chronic kidney disease, an increase in CTRP1 levels is associated with a lesser degree of disease progression. CTRP1 stimulates aldosterone synthesis in the adrenal cortex by affecting aldosterone synthase expression. In dehydration, an increase in CTRP1 concentration helps to maintain normotension. It participates in processes related to the proliferation and maturation of chondrocytes. It also promotes atherosclerosis, and a surge in its concentration is correlated with a higher cardiovascular risk in patients with coronary atherosclerosis. In vascular smooth muscle cells, it induces the expression of proinflammatory cytokines. An increase in CTRP1 levels is correlated with the progression of the neoplastic process in patients with glioblastoma.

Abstract
C1q/tumor necrosis factor-related protein 1 (CTRP1) has recently been identified as a key regulator of cardio-metabolic diseases. It has been reported that CTRP1 could inhibit the hypertrophic response in mice. However, the effect of CTRP1 on sepsis-induced cardiomyopathy remains completely unknown. Cardiomyocyte-specific CTRP1 overexpression was achieved using an adeno associated virus system in mice. CTRP1 deficiency mice were also subjected to lipopolysaccharide (LPS) injection. We found that CTRP1 overexpression improved survival rate and cardiac function, and suppressed myocardial inflammation, oxidative damage and apoptosis without affecting metabolic disturbance in LPS-treated mice. CTRP1 depletion further decreased survival rate and cardiac function, and promoting myocardial inflammation, oxidative damage and apoptosis in sepsis mice. In addition, we showed that CTRP1 provided protection against LPS-induced cell injury in vitro. CTRP1 activated sirtuin 1 (Sirt1) signaling pathway, and Sirt1 inhibition or deficiency blocked CTRP1-mediated cardioprotective effects in vivo and in vitro. More importantly, our study found that recombinant human globular domain of CTRP1 infusion was also capable of blocking sepsis-induced cardiomyopathy in mice. In conclusion, CTRP1 improved survival rate and attenuated LPS-induced cardiac injury via activating Sirt1 signaling pathway.

Abstract
BACKGROUND Kawasaki disease (KD) is characterized as a self-limited systemic vasculitis. C1q/tumor necrosis factor-related protein-1 (CTRP1) had been associated with the occurrence of vasculitis in KD. Methylation at the promoter region of certain genes was reported to be involved in the development process of KD. This study aims to investigate the methylation levels of CTRP1 in KD, as well as, its potential to predict coronary artery aneurysms (CAAs). METHODS 31 patients with KD and 14 healthy controls (HCs) were recruited into this study. The KD group was further divided into KD with CAA (KD-CAAs) group and KD without NCAAs (KD-NCAAs) group. Methylation levels of CpG sites were determined by MethylTarget sequencing, a method that uses multiple targeted CpG methylation analysis. RESULTS The methylation levels of CTRP1 promoter region in the KD group were lower than that in the HC group at all predicted CpG sites, especially at sites 34, 51, 69, 79, 176 and 206. Compared with KD-CAAs group, the methylation levels of almost every CpG sites of CTRP1 were increased in the KD-NCAAs group, with site 69 and 154 found to be strongly related to the occurrence of CAAs. CONCLUSIONS The difference in methylation levels of CTRP1 promoter may be involved in the development process of KD, and may be a potential predictive marker for the occurrence of CAAs.

Abstract
AIMS/INTRODUCTION As a member of the tumor necrosis factor-α-related protein family, complement-1q tumor necrosis factor-α-related protein isoform 5 (CTRP5) has been found to be associated with obesity and insulin resistance (IR). Previous studies in humans and animals have reported contradictory results related to the association between CTRP5 and IR. The purpose of the present study was to explore the relationship between CTRP5 and IR through a cross-sectional study and drug intervention study of type 2 diabetes patients. MATERIALS AND METHODS A cross-sectional study was carried out with 118 newly diagnosed patients with type 2 diabetes and 116 healthy adults. In an interventional study, 78 individuals with newly diagnosed type 2 diabetes received sodium-glucose cotransporter 2 inhibitor (dapagliflozin) treatment for 3 months. Circulating CTRP5 concentrations were measured by enzyme-linked immunosorbent assay. RESULTS Serum CTRP5 concentrations were markedly reduced in patients with type 2 diabetes when compared with those of healthy individuals (P < 0.01). When considering the study population as a whole, individuals with IR (homeostasis model of assessment of IR ≥2.78) had lower CTRP5 concentrations than the individuals without IR (homeostasis model of assessment of IR <2.78; P < 0.01). Serum CTRP5 negatively correlated with age, body mass index, waist-to-hip ratio, Systolic blood pressure, triglyceride, total cholesterol, glycated hemoglobin, fasting blood glucose, 2-h blood glucose, fasting insulin and homeostasis model of assessment of IR. After 12 weeks of sodium-glucose cotransporter 2 inhibitor treatment, serum CTRP5 levels in type 2 diabetes patients were significantly reduced accompanied with ameliorated glycometabolism and IR compared with before treatment (P < 0.01). CONCLUSIONS CTRP5 is likely a marker for type 2 diabetes in humans.

Abstract
This study aimed to investigate the correlation between complement C1q tumor necrosis factor-related protein 1 (CTRP1) and subclinical target organ damage (STOD) in essential hypertension (EH). 720 patients were enrolled in this study, including 360 healthy subjects and 360 patients with EH. The EH group included 183 patients complicated with STOD and 177 patients without STOD. In the STOD group, there were 87 patients with left ventricular hypertrophy (LVH), 32 patients with microalbuminuria (MAU), and 58 patients with complication of LVH and MAU. Enzyme-linked immunosorbent assay (ELISA) was used to detect the CTRP1, adiponectin (APN), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). We found that CTRP1 levels were higher in patients with EH than those in healthy subjects; moreover, the level of CTRP1 of patients in the group complicated with EH and STOD was increased compared with EH patients without STOD. CTRP1 levels in the group complicated with LVH and MAU were significantly higher than those in the LVH group and the MAU group. Furthermore, APN, CTRP1, and IL-6 were three factors that influenced the STOD of EH patients, among which CTRP1 and IL6 were positively related with the complication of hypertension and STOD. In conclusion, CTRP1 levels are increased and associated with the STOD (heart and kidney) in essential hypertension, which can be regarded as a novel biomarker in the prediction of prognosis for patients with essential hypertension.

Abstract
Objective Complement C1q tumor necrosis factor-related proteins (CTRPs), belonging to the CTRP superfamily, are extensively involved in regulating metabolism and the immune-inflammatory response. The inflammatory process is linked to the pathogenesis of coronary artery disease (CAD). Here, we investigated the association of serum levels of CTRP1 with CAD. Methods Study participants were divided into two groups according to the results of coronary angiography: a control group (n = 63) and a CAD group (n = 76). The concentrations of serum CTRP1 and inflammatory cytokines were determined by enzyme-linked immunosorbent assay. Further analysis of CTRP1 levels in individuals with different severities of CAD was conducted. The CAD severity was assessed by Gensini score. Results Serum levels of CTRP1 were significantly higher in CAD patients than in controls (17.24 ± 1.07 versus 9.31 ± 0.56 ng/mL), and CTRP1 levels increased with increasing severity of CAD. CTRP1 levels were positively correlated with concentrations of tumor necrosis factor-α and interleukin-6. Multiple logistic regression analysis showed that CTRP1 was significantly associated with CAD. Conclusions Our data showed close associations of serum CTRP1 levels with the prevalence and severity of CAD, indicating that CTRP1 can be regarded as a novel and valuable biomarker for CAD.

Abstract
High-intensity interval training (HIIT) is known to be an effective exercise training regimen to improve energy substrate metabolism and insulin sensitivity. However, the underlying mechanisms of improvement in insulin sensitivity due to HIIT have not yet been fully clarified. C1q/tumor necrosis factor-related protein (CTRP) 1 and CTRP9, which are adiponectin paralogs and novel adipokines, have favorable effects on energy substrate metabolism and insulin sensitivity. The purpose of this study was to investigate the effects of a single bout of HIIT on CTRP1 and CTRP9 secretions in healthy men. Eight healthy male subjects (mean ± SE: age, 23.4 ± 1.1 years; height, 172.1 ± 1.7 cm; body mass, 68.0 ± 2.0 kg; body mass index, 22.9 ± 0.5 kg/m2) participated in this study. They performed a single bout of HIIT consisted of four 30-s maximal cycling bouts with 4 min of rest between bouts using a cycle ergometer. Blood samples were collected before the exercise, at 0 (immediately after the exercise), 15, 30, and 120 min after the single bout of HIIT. Serum CTRP1, CTRP9, and high-molecular-weight (HMW) adiponectin concentrations were measured using enzyme-linked immunosolvent assay kits. CTRP1 concentration significantly increased at 120 min after the HIIT. CTRP9 concentration also significantly increased immediately after the single bout of HIIT. In contrast, there were no significant differences in HMW adiponectin concentration before and after the acute HIIT. These findings suggest that a single bout of HIIT may stimulate CTRP1 and CTRP9 secretions in healthy men.

Abstract
Objective: Metabolic changes and inflammation are involved in the pathogenesis of preeclampsia. Complement C1q tumor necrosis factor-related protein-1 (CTRP-1) is a pleiotropic molecule that possesses insulin-sensitizing effects and is also involved in lipid metabolism and inflammatory responses. The aim of the study was to investigate CTRP-1 levels in pregnancies with preeclampsia.Material and methods: Serum concentrations of CTRP-1 were measured in 29 pregnant women with early-onset preeclampsia (EOPE), 24 pregnant women with late-onset preeclampsia (LOPE), and 26 women with uncomplicated pregnancies using an enzyme-linked immunosorbent assay method.Results: Patients with both EOPE and LOPE had significantly higher serum concentrations of CTRP-1 compared to the healthy controls (p < .001). However, no significant difference was found between the EOPE and LOPE groups regarding CTRP-1 levels (p = 1.000). Correlation analysis showed that CTRP-1 levels were positively correlated with systolic blood pressure (p < .001), diastolic blood pressure (p < .001), and mean UtA PI (p < .001) but negatively correlated with gestational age at delivery (p = .001) and birth weight (p < .001).Conclusions: Serum CTRP-1 levels were significantly higher in patients with both EOPE and LOPE than in healthy pregnant women.

Abstract
RATIONALE Complement C1q tumor necrosis factor related proteins (C1QTNFs) have been reported to have diverse biological influence on the cardiovascular system. C1QTNF1 is a member of the CTRP superfamily. C1QTNF1 is expressed in the myocardium; however, its function in myocytes has not yet been investigated. OBJECTIVE To systematically investigate the roles of C1QTNF1 in angiotensin II (Ang II)-induced cardiac hypertrophy. METHODS AND RESULTS C1QTNF1 knock-out mice were used with the aim of determining the role of C1QTNF1 in cardiac hypertrophy in the adult heart. Data from experiments showed that C1QTNF1 was up-regulated during cardiac hypertrophic processes, which were triggered by increased reactive oxygen species. C1QTNF1 deficiency accelerated cardiac hypertrophy, fibrosis, inflammation responses, and oxidative stress with deteriorating cardiac dysfunction in the Ang II-induced cardiac hypertrophy mouse model. We identified C1QTNF1 as a negative regulator of cardiomyocyte hypertrophy in Ang II-stimulated neonatal rat cardiomyocytes using the recombinant human globular domain of C1QTNF1 and C1QTNF1 siRNA. Injection of the recombinant human globular domain of C1QTNF1 also suppressed the Ang II-induced cardiac hypertrophic response in vivo. The anti-hypertrophic effects of C1QTNF1 rely on AMPKa activation, which inhibits mTOR P70S6K phosphorylation. An AMPKa inhibitor abrogated the anti-hypertrophic effects of the recombinant human globular domain of C1QTNF1 both in vivo and vitro. Moreover, C1QTNF1-mediated AMPKa activation was triggered by the inhibition of PDE1-4, which subsequently activated the cAMP/PKA/LKB1 pathway. CONCLUSION Our results demonstrated that C1QTNF1 improves cardiac function and inhibits cardiac hypertrophy and fibrosis by increasing and activating AMPKa, suggesting that C1QTNF1 could be a therapeutic target for cardiac hypertrophy and heart failure.

Abstract
BackgroundTo investigate the serum C1q/tumor necrosis factor-related protein-1 (CTRP1) levels in children with acute Kawasaki disease (KD), as well as the relationship between CTRP1 levels and laboratory variables.MethodsEighty-seven children with KD and 38 healthy controls (HCs) were included in this study. General characteristics were obtained from all subjects. Serum CTRP1 levels in all subjects and serum tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) levels in KD patients were measured using enzyme-linked immunosorbent assay.ResultsCompared with the HC group, serum CTRP1 levels were significantly elevated in the KD group. Significantly higher serum TNF-α, IL-1β, IL-6, and CTRP1 levels were observed in patients with KD with coronary artery lesions (KD-CALs) than in patients with KD without CALs (KD-NCALs). Serum CTRP1 levels were positively correlated with white blood cell counts (WBC), percentage of neutrophils (N%), thrombin time (TT), procalcitonin (Pct), TNF-α, IL-1β, and IL-6 levels. Meanwhile, CTRP1 levels were negatively correlated with the percentage of leukomonocytes (L%) in KD patients. Furthermore, serum CTRP1 levels were positively correlated with the time point of intravenous immunoglobulin (IVIG), WBC, N%, TNF-α, IL-1β, and IL-6 levels in the KD-CAL group.ConclusionCTRP1 may participate in the process of vasculitis and blood coagulation during the acute phase of KD.

Abstract
Peroxisome-proliferator-activated-receptor-gamma (PPAR-γ) is implicated, in some capacity, in the pathogenesis of pulmonary arterial hypertension (PAH). Rosiglitazone, an oral antidiabetic and PPAR-γ agonist, has the potential to dilate pulmonary arteries and to attenuate arterial remodeling in PAH. Here, we sought to test the hypothesis that rosiglitazone can be repurposed as inhaled formulation for the treatment of PAH. We have tested this conjecture by preparing and optimizing poly(lactic-co-glycolic) acid (PLGA) based particles of rosiglitazone, assessing the drug particles for pulmonary absorption, investigating the efficacy of the plain versus particulate drug formulation in improving the respiratory hemodynamics in PAH animals, and finally studying the effect of the drug in regulating the molecular markers associated with PAH pathogenesis. The optimized particles were slightly porous and spherical, and released 87.9% ± 6.7% of the drug in 24 h. The elimination half-life of the drug formulated in PLGA particles was 2.5-fold greater than that of the plain drug administered via the same route at the same dose. The optimized formulation, given via the pulmonary route, produced pulmonary selective vasodilation in PAH animals, but oral rosiglitazone had no effect in pulmonary hemodynamics. Rosiglitazone ameliorates the pathogenesis of PAH by balancing the molecular regulators involved in the vasoconstriction and vasodilation of human pulmonary arterial smooth muscle cells. All in all, data generated using intact animal and cellular models point to the conclusion that PLGA particles of an antidiabetic drug can be used for the treatment of a different disease, PAH.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease occurs in significant percentage of general population. NAFLD is closely associated with entire spectrum of metabolic-related disorders including diabetes, obesity, and cardiovascular diseases. Considering several similar pathways underpinning metabolic disorders, presence of common molecular mediators contributing to pathomechanism of these disorders is expected. Mounting evidence has demonstrated important role of adipokines in the context of NAFLD. Adipokines produced by different tissues, mainly adipose, modulate numerous pathways including glucose and fatty acid metabolism and inflammation. CTRPs (C1q/TNF-related proteins) are a recently identified family of adipokines in which adiponectin is the most well-known ones. CTRP1 is a member of this family which has captured attention in recent years. CTRP1 enhances glucose and fatty acid oxidation, improves insulin sensitivity, attenuates plaque formation, and increases aldosterone production. Hence, various roles in metabolic pathways can link CTRP1 to NAFLD pathogenesis.

Adipocyte C1QTNF5 expression is BMI-dependently related to early adipose tissue dysfunction and systemic CTRP5 serum levels in obese children. Int J Obes (Lond) 2016; 41:955-963. [PMID: 28239164 DOI: 10.1038/ijo.2017.54] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2016] [Revised: 01/29/2017] [Accepted: 02/19/2017] [Indexed: 12/30/2022]
Abstract
BACKGROUND/OBJECTIVES The recently identified adipocytokine C1QTNF5 (encodes for CTRP5) has been demonstrated to inhibit pro-metabolic insulin signaling in adipocytes. We hypothesized that adipocyte C1QTNF5 expression in subcutaneous (sc) adipose tissue (AT) would correlate with the degree of obesity, systemic CTRP5 serum levels, and early AT and metabolic dysfunction in children. SUBJECTS/METHODS Sc AT samples were obtained from 33 healthy Caucasian lean children aged 10.06±4.84 years and 42 overweight and obese children aged 13.34±3.12 years. C1QTNF5 expression in sc AT as well as in investigated cell lines was assessed by quantitative real-time PCR. Systemic CTRP5 levels were assessed by ELISA. RESULTS C1QTNF5 expression in sc adipocytes increased with body mass index (BMI) standard deviation score (SDS; R=0.48, P<0.001), body fat percentage (R=0.4, P=0.004), adipocyte number (R=0.69, P<0.001) and systemic CTRP5 serum levels (R=0.28, P=0.025) whereas expression in the stromal vascular fraction (SVF) was inversely correlated with BMI SDS (R=-0.24, P=0.04). Multiple regression analysis confirmed that BMI SDS was the strongest independent predictor for C1QTNF5 expression in sc adipocytes. SVF C1QTNF5 levels strongly correlated with SVF CD31 expression (R=0.54, P<0.001) indicating expression by endothelial cells. Primary human endothelial cells demonstrated stronger expression compared with human Simpson-Golahbi-Behmel syndrome pre-adipocytes and adipocytes. Adipocyte C1QTNF5 expression levels were BMI-dependently related to fasting insulin (R=0.3, P=0.03) and leptin serum levels (R=0.5, P<0.001). Sc AT samples containing crown-like structures (CLS) demonstrated increased adipocyte C1QTNF5 expression compared to CLS-negative samples (P=0.03). Functionally, tumor necrosis factor (TNF)α caused a fourfold induction of C1QTNF5 in human adipocytes (P<0.001) and a 50% reduction in primary human endothelial cells (P<0.001). CONCLUSIONS In children adipocyte C1QTNF5 expression is already strongly related to the degree of obesity and is associated with obesity-related AT alterations, systemic CTRP5 serum levels as well as circulating markers of metabolic disease and is positively regulated by TNFα in vitro.

Abstract
C1q/TNF-related protein 1 (CTRP1) is a conserved plasma protein of the C1q family with notable metabolic and cardiovascular functions. We have previously shown that CTRP1 infusion lowers blood glucose and that transgenic mice with elevated circulating CTRP1 are protected from diet-induced obesity and insulin resistance. Here, we used a genetic loss-of-function mouse model to address the requirement of CTRP1 for metabolic homeostasis. Despite similar body weight, food intake, and energy expenditure, Ctrp1 knockout (KO) mice fed a low-fat diet developed insulin resistance and hepatic steatosis. Impaired glucose metabolism in Ctrp1 KO mice was associated with increased hepatic gluconeogenic gene expression and decreased skeletal muscle glucose transporter glucose transporter 4 levels and AMP-activated protein kinase activation. Loss of CTRP1 enhanced the clearance of orally administered lipids but did not affect intestinal lipid absorption, hepatic VLDL-triglyceride export, or lipoprotein lipase activity. In contrast to triglycerides, hepatic cholesterol levels were reduced in Ctrp1 KO mice, paralleling the reduced expression of cholesterol synthesis genes. Contrary to expectations, when challenged with a high-fat diet to induce obesity, Ctrp1 KO mice had increased physical activity and reduced body weight, adiposity, and expression of lipid synthesis and fibrotic genes in adipose tissue; these phenotypes were linked to elevated FGF-21 levels. Due in part to increased hepatic AMP-activated protein kinase activation and reduced expression of lipid synthesis genes, Ctrp1 KO mice fed a high-fat diet also had reduced liver and serum triglyceride and cholesterol levels. Taken together, these results provide genetic evidence to establish the significance of CTRP1 to systemic energy metabolism in different metabolic and dietary contexts.

Abstract
Understanding the mechanisms linking obesity with hypertension is important in the current obesity epidemic as it may improve therapeutic interventions. Plasma aldosterone levels are positively correlated with body mass index and weight loss in obese patients is reported to be accompanied by decreased aldosterone levels. This suggests a relationship between adipose tissue and the production/secretion of aldosterone. Aldosterone is synthesized principally by the adrenal glands, but its production may be regulated by many factors, including factors secreted by adipocytes. In addition, studies have reported local synthesis of aldosterone in extra-adrenal tissues, including adipose tissue. Experimental studies have highlighted a role for adipocyte-secreted aldosterone in the pathogenesis of obesity-related cardiovascular complications via the mineralocorticoid receptor. This review focuses on how aldosterone secretion may be influenced by adipose tissue and the importance of these mechanisms in the context of obesity-related hypertension.

Abstract
Background Complement C1q tumor necrosis factor related proteins (CTRPs) have been proved to have diverse biological influences on cardiovascular system. CTRP 1 is a member of the CTRP superfamily, however, the relevance with coronary artery disease (CAD) are seldom explored. This study was designed to investigate the correlation between serum levels of CTRP 1 and CAD. Methods CTRP 1 levels of 150 CAD patients and 50 non-CAD subjects were determined by enzymelinked immunosorbent assay. Further analysis of CTRP 1 levels in different stages and lesion vessels of CAD were conducted. Results Serum levels of CTRP 1 in CAD patients were significantly elevated, and it was increased with the severity of CAD. CTRP 1 level in acute myocardial infarction group was much higher than that in stable/unstable angina and non-CAD groups. And significant differences of CTRP 1 were also found between single-vessel disease and triple-vessel disease. Multiple logistic regression analysis showed that CTRP 1 was an independent risk factor of the occurrence of myocardial infarction. Conclusions Increased serum CTRP 1 levels were closely associated with the prevalence and severity of CAD, it might be regarded as a marker for myocardial infarction.

Abstract
Obese subjects often have hypertension and related cardiovascular and renal diseases, and this has become a serious worldwide health problem. In obese subjects, impaired renal-pressure natriuresis causes sodium retention, leading to the development of salt-sensitive hypertension. Physical compression of the kidneys by visceral fat and activation of the sympathetic nervous system, renin-angiotensin systems (RAS), and aldosterone/mineralocorticoid receptor (MR) system are involved in this mechanism. Obese subjects often exhibit hyperaldosteronism, with increased salt sensitivity of blood pressure (BP). Adipose tissue excretes aldosterone-releasing factors, thereby stimulating aldosterone secretion independently of the systemic RAS, and aldosterone/MR activation plays a key role in the development of hypertension and organ damage in obesity. In obese subjects, both salt sensitivity of BP, enhanced by obesity-related metabolic disorders including aldosterone excess, and increased dietary sodium intake are closely related to the incidence of hypertension. Some salt sensitivity-related gene variants affect the risk of obesity, and together with salt intake, its combination is possibly associated with the development of hypertension in obese subjects. With high salt levels common in modern diets, salt restriction and weight control are undoubtedly important. However, not only MR blockade but also new diagnostic modalities and therapies targeting and modifying genes that are related to salt sensitivity, obesity, or RAS regulation are expected to prevent obesity and obesity-related hypertension.

Abstract
The goal of this study was to investigate whether circulating C1q/TNF-α-related protein 1 (CTRP1) levels are associated with diabetes. In addition, relationships between CTRP1 and other diabetes-related cytokines were elucidated, including adiponectin and fibroblast growth factor 21 (FGF21). A total of 178 subjects (78 men and 100 women) aged 29-70 years (mean age, 46.1 years) were randomly selected. The sera from a normal glucose tolerance group (n = 68) and a prediabetes/type 2 diabetes group (n = 110) were collected; then, circulating levels of CTRP1, adiponectin, and FGF21 were determined via enzyme-linked immunosorbent assay in all sera. Subjects with either prediabetes or diabetes exhibited higher circulating CTRP1 levels than healthy subjects. Sera analysis revealed that CTRP1 was positively correlated with age, body mass index, fasting blood glucose, and circulating FGF21 levels. However, CTRP1 was negatively correlated with total cholesterol and total circulating adiponectin levels in univariate analysis. In addition, multivariate analysis found that CTRP1 was independently associated with age, fasting blood glucose, and circulating FGF21 levels. CTRP1 was correlated with homeostasis model assessment-β (HOMA-β), but no correlation was observed with HOMA-insulin resistance. In conclusion, circulating CTRP1 levels are increased in subjects with type 2 diabetes and are positively associated with circulating FGF21 levels.

METHODS AND RESULTS We analysed CTRP1 levels in sera of CAD patients (n = 451) and non-CAD controls (n = 686), and in coronary endarterectomy specimens (n = 32), non-atherosclerotic internal mammary arteries (n = 26), aortic atherosclerotic plaques (n = 15), and non-atherosclerotic aortic samples (n = 10). C1q/TNF-related protein-levels were higher in sera, endarterectomy specimens, aortic atherosclerotic plaques, and peripheral blood mononuclear cells (PBMCs) from CAD patients compared with controls, and were related to CAD severity. The production of CTRP1 was profusely induced by inflammatory cytokines and itself caused a concentration-dependent expression of adhesion molecules and inflammatory markers in human endothelial cells, human peripheral blood monocytes, and THP-1 cells. C1q/TNF-related protein-1 induced p38-dependent monocyte-endothelium adhesion in vitro and the recruitment of leucocytes to mesenteric venules in C57BL/6 mice. Immunohistochemistry of atherosclerotic femoral arteries exhibited CD68 and VE-cadherin loci-associated increased CTRP1 expression in plaques. Compared with saline, intraperitoneal injection of recombinant CTRP1 protein (200 μg/kg) every other day promoted atherogenesis in apoE(-/-) mice at 24 weeks. However, pro-atherogenic effects were significantly attenuated in CTRP1(-/-)/apoE(-/-) double-knockout mice compared with apoE(-/-) mice, with a consistent decrease in vascular adhesion molecule, phospho-p38 and TNF-α expression and macrophage infiltration in plaque in CTRP1(-/-) and double-knockout mice. Tumour necrosis factor-α-induced expression of adhesion molecules and cytokines were lower in primary endothelial cells and macrophages from CTRP(-/-) mice than in those from C57BL/6 mice. CONCLUSION C1q/TNF-related protein-1 is a marker of atherosclerosis in humans and promotes atherogenesis in mice.

Abstract
Obesity is associated with an increased risk of cardiovascular disease. C1q/TNF-related protein (CTRP)-1 is a poorly characterized adipokine that is up-regulated in association with ischemic heart disease. We investigated the role of CTRP1 in myocardial ischemia injury. CTRP1-knockout mice showed increased myocardial infarct size, cardiomyocyte apoptosis, and proinflammatory gene expression after I/R compared with wild-type (WT) mice. In contrast, systemic delivery of CTRP1 attenuated myocardial damage after I/R in WT mice. Treatment of cardiomyocytes with CTRP1 led to reduction of hypoxia-reoxygenation-induced apoptosis and lipopolysaccharide-stimulated expression of proinflammatory cytokines, which was reversed by inhibition of sphingosine-1-phosphate (S1P) signaling. Treatment of cardiomyocytes with CTRP1 also resulted in the increased production of cAMP, which was blocked by suppression of S1P signaling. The antiapoptotic and anti-inflammatory actions of CTRP1 were cancelled by inhibition of adenylyl cyclase or knockdown of adiponectin receptor 1. Furthermore, blockade of S1P signaling reversed CTRP1-mediated inhibition of myocardial infarct size, apoptosis, and inflammation after I/R in vivo. These data indicate that CTRP1 protects against myocardial ischemic injury by reducing apoptosis and inflammatory response through activation of the S1P/cAMP signaling pathways in cardiomyocytes, suggesting that CTRP1 plays a crucial role in the pathogenesis of ischemic heart disease.

Circulating level of CTRP1 in patients with nonalcoholic fatty liver disease (NAFLD): is it through insulin resistance? PLoS One 2015; 10:e0118650. [PMID: 25767880 PMCID: PMC4358971 DOI: 10.1371/journal.pone.0118650] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2014] [Accepted: 01/08/2015] [Indexed: 01/01/2023] Open
Abstract
Nonalcoholic fatty liver disease (NAFLD) is considered as one of the most common liver diseases. It is robustly linked to obesity and insulin resistance and is regarded as hepatic manifestation of metabolic syndrome (MetS). Adipokines are involved in the pathophysiology of liver diseases. The aim of this study was to evaluate the plasma concentrations of CTRP1 (complement-C1q TNF-related protein 1) in 22 patients with NAFLD, 22 patients with type 2 diabetes mellitus (T2DM), 22 patients with NAFLD+T2DM and 21 healthy controls, as well as their correlation with the level of metabolic and hepatic parameters. Plasma concentration of CTRP1 was measured with ELISA method. Plasma concentration of CTRP1 in patients with NAFLD, T2DM and NAFLD+T2DM were significantly higher than healthy subjects (p<0.0001). Moreover, we observed significant positive correlations between plasma level of CTRP1 and fasting blood glucose (FBG) (p<0.001), homeostasis model assessment of insulin resistance (HOMA-IR) (p<0.001), body mass index (BMI) (p = 0.001), alanine amino transferase (ALT) (p = 0.002), gamma glutamyl transferase (γ-GT) (p<0.001) and liver stiffness (LS) (p<0.001). Our results indicate the strong association of CTRP1 with insulin resistance in NAFLD. Also, it seems that CTRP1 can be considered as an emerging biomarker for NAFLD, however, more studies are necessary to unravel the role of CTRP1 in NAFLD pathogenesis.

Abstract
OBJECTIVE Obesity is a major risk factor for cardiovascular disease. Recent evidence demonstrates that dysregulation of fat-derived hormones, also known as adipokines, is linked with the pathogenesis of obesity-related disorders including coronary artery disease (CAD). Here, we investigated whether circulating level of an adipokine C1q/TNF-related protein (CTRP) 1 is associated with the prevalence of CAD. METHODS AND RESULTS Consecutive 76 male CAD patients were enrolled from inpatients that underwent coronary angiography. Sixty four healthy male subjects served as controls. Plasma CTRP1 concentration was determined by enzyme-linked immunosorbent assay. CTRP1 levels were correlated positively with systolic blood pressure (BP) and triglyceride levels, and negatively with HDL cholesterol levels in all subjects. Plasma levels of CTRP1 were significantly higher in CAD patients than in control subjects (CAD: 443.3±18.6 ng/ml, control: 307.8±21.5 ng/ml, p<0.001). Multiple logistic regression analysis with body mass index, systolic BP, glucose, total cholesterol, HDL cholesterol, triglyceride, adiponectin and CTRP1 revealed that CTRP1 levels, together with systolic BP and HDL cholesterol, correlated with CAD. CONCLUSIONS Our data indicate the close association of high CTRP1 levels with CAD prevalence, suggesting that CTRP1 represents a novel biomarker for CAD.

Abstract
Background Complement-C1q TNF-related protein 1 (CTRP1), a member of the CTRP superfamily, possesses anti-inflammatory and anti-diabetic effects in mice. However, the clinical relevance of CTRP1 has been seldom explored. The current study aimed to investigate the association of circulating CTRP1 and type 2 diabetes mellitus (T2DM) in a Chinese population. Design and Methods Serum CTRP1 and adiponectin levels of 96 T2DM patients and 85 healthy subjects were determined by ELISA, and their associations with adiposity, glucose and lipid profiles were studied. In a subgroup of this study, the 75-g oral glucose tolerance test (OGTT) was performed in 20 healthy and 20 T2DM subjects to evaluate the relationship among serum levels of CTRP1 and adiponectin, insulin secretion and insulin sensitivity. Results Serum CTRP1 levels were significantly increased in patients with T2DM, compared with healthy controls (p<0.001). Similar to adiponectin, serum levels of CTRP1 were significantly correlated to several parameters involved in glucose metabolism and insulin resistance, and independently associated with fasting glucose levels (p<0.05) after BMI and gender adjustments. Furthermore, CTRP1 levels were positively correlated to insulin secretion, while negatively to insulin sensitivity, as measured by OGTT. Conclusion CTRP1 is a novel adipokine associated with T2DM in humans. The paradoxical increase of serum CTRP1 levels in T2DM subjects may be due to a compensatory response to the adverse glucose and lipid metabolism, which warrants further investigation.
