Adipokines and cardiovascular disease

Background: Oncostatin M, a novel adipokine, plays a role in oogenesis, lipogenesis, and inflammation and may contribute to polycystic ovary syndrome pathogenesis and related metabolic problems. Adipokines are believed to contribute to developing polycystic ovary syndrome and its accompanying metabolic parameters, such as dyslipidemia, insulin resistance, and cardiovascular diseases. Methods: In this case-control study, the patients were grouped in a 1:1 ratio into either the polycystic ovary syndrome ( n = 32) or the control group ( n = 32)...

Cornelian cherry ( Cornus mas L.) fruits, abundant in iridoids and anthocyanins, are natural products with proven beneficial impacts on the functions of the cardiovascular system and the liver. This study aims to assess and compare whether and to what extent two different doses of resin-purified cornelian cherry extract (10 mg/kg b.w. or 50 mg/kg b.w.) applied in a cholesterol-rich diet rabbit model affect the levels of sterol regulatory element-binding protein 1c (SREBP-1c) and CCAAT/enhancer binding protein α (C/EBPα), and various liver X receptor-α (LXR-α), peroxisome proliferator-activated receptor-α (PPAR-α), and peroxisome proliferator-activated receptor-γ (PPAR-γ) target genes...

Vascular remodeling plays a vital role in hypertensive diseases and is an important target for hypertension treatment. Irisin, a newly discovered myokine and adipokine, has been found to have beneficial effects on various cardiovascular diseases. However, the pharmacological effect of irisin in antagonizing hypertension-induced vascular remodeling is not well understood. In the present study, we investigated the protection and mechanisms of irisin against hypertension and vascular remodeling induced by angiotensin II (Ang II)...

UNLABELLED: Cardiovascular disease (CVD) in type 1 diabetes mellitus (T1DM) is preceded by asymptomatic changes in the geometry of the heart. The only symptoms of the beginning of cardiac remodeling and concomitant predictors of an unfavorable cardiovascular prognosis are: thickening of epicardial fat (EAT), secreting a number of adipokines, and cardiospecific miRNAs. To improve the effectiveness of prevention of CVD in young patients with DM1, a search was made for structural-functional and epigenetic markers...

OBJECTIVE: Excessive obesity can lead to dysfunction in adipose tissue, which contributes to the development of comorbidities associated with obesity, such as type 2 diabetes (T2D), cardiovascular and cerebrovascular disease, among others. Previous research has mainly focused on the Vanin family in systemic inflammatory diseases or predicting its role in tumor prognosis, while neglecting its role as a secretory protein in adipose tissue inflammation and metabolism. The objective of this study was to compare the changes in Vanin-2 levels in the circulating blood of normal and obese individuals, and to assess its correlation with inflammatory factors in vivo ...

This review provides an overview of the key role played by perivascular adipose tissue (PVAT) in the protection of cardiovascular health. PVAT is a specific type of adipose tissue that wraps around blood vessels and has recently emerged as a critical factor for maintenance of vascular health. Through a profound exploration of existing research, this review sheds light on the intricate structural composition and cellular origins of PVAT, with a particular emphasis on combining its regulatory functions for vascular tone, inflammation, oxidative stress, and endothelial function...

BACKGROUND: Neuregulin-4 (Nrg4), a novel brown fat-enriched factor, has been reported to play a crucial role in developing metabolic disorders. The current case-control study aimed to investigate the association between serum Nrg4 and coronary artery disease (CAD). METHODS: This study enrolled 43 patients with CAD and 43 subjects with normal coronary arteries diagnosed by coronary angiography. Anthropometric and biochemical parameters were measured and recorded...

BACKGROUND AND AIMS: Obesity predisposes to metabolic and cardiovascular diseases. Adipose tissue inflammation and systemic inflammation contribute to these complications. There are strong sex differences in adipose tissue distribution and in systemic inflammation. Women have more subcutaneous adipose tissue (SAT) and less visceral adipose tissue (VAT) than men. We explored the sex differences in the association between the different adipose compartments and inflammatory markers that are important in cardiometabolic disease pathophysiology...

Adipsin is an adipokine predominantly synthesized in adipose tissues and released into circulation. It is also known as complement factor-D (CFD), acting as the rate-limiting factor in the alternative complement pathway and exerting essential functions on the activation of complement system. The deficiency of CFD in humans is a very rare condition. However, complement overactivation has been implicated in the etiology of numerous disorders, including cardiovascular disease (CVD). Increased circulating level of adipsin has been reported to promote vascular derangements, systemic inflammation, and endothelial dysfunction...

PURPOSE OF REVIEW: Among subtypes of cardiovascular disease, obesity has a potent and unique association with heart failure (HF) that is unexplained by traditional cardiovascular risk mediators. The concomitant rise in the prevalence of obesity and HF necessitates better understanding of their relationship to develop effective prevention and treatment strategies. The purpose of this review is to provide mechanistic insight regarding the link between obesity and HF by elucidating the direct and indirect pathways linking the two conditions...

BACKGROUND: To analyze the association of serum Asprosin concentrations with heart failure (HF). METHODS: A total of 103 patients with HF were included in the HF group, and 103 patients with health checkups were included in the non-HF group. The serum Asprosin levels of the two groups were measured, and relevant clinical data were collected for statistical analysis. RESULTS: Compared with the non-HF group, the serum Asprosin concentration was significantly higher in the HF group, and the difference was statistically significant (P < 0...

Perivascular adipose tissue (PVAT), a fat layer that provides structural support to the blood vessels, is a cushion protecting the vessel wall from neighbouring tissues during contraction and relaxation. PVAT actively regulates vascular tone by secreting vasoactive (vasodilatory and vasoconstrictive) factors (e.g., adipokines, batokines, and lipokines) or microRNA (miRNA)-containing exosomes to reduce the hyperreactivity induced by obesity. Of particular interest are adipocyte-derived exosomal miRNAs, which act as crucial regulators, counteracting the detrimental effects of obesity on cardiovascular well-being...

BACKGROUND: The assessment of obesity-related health risks has traditionally relied on the Body Mass Index and waist circumference, but their limitations have propelled the need for a more comprehensive approach. The differentiation between visceral (VIS) and subcutaneous (SC) fat provides a finer-grained understanding of these risks, yet practical assessment methods are lacking. We hypothesized that combining the SC-VIS fat ratio with non-invasive biomarkers could create a valuable tool for obesity-related risk assessment...

Cushing syndrome (CS), characterised by endogenous or exogenous glucocorticoid hormone excess, is associated with several systemic complications, including impaired glucose metabolism, which often becomes clinically manifest as diabetes mellitus (DM). In addition, CS can harm the arterial wall because of hyperglycaemia, dyslipidaemia, hepatic steatosis, and central obesity. These metabolic disorders promote atherosclerosis by synthesising adipokines, leptin, and proinflammatory cytokines. Lower limb arterial complications in CS are common and significantly impact morbidity and mortality...

Heart failure (HF) is a clinical syndrome characterized by myocardial dysfunction leading to inefficient blood filling or ejection. Regardless of the etiology, various mechanisms, including adipokine hypersecretion, proinflammatory cytokines, stem cell proliferation, oxidative stress, hyperglycemic toxicity, and autonomic nervous system dysregulation in the pericardial fat (PCF), contribute to the development of HF. PCF has been directly associated with cardiovascular disease, and an increased PCF volume is associated with HF...

Omentin (intelectin) was first detected in the visceral omental adipose tissue. It has mainly two isoforms, omentin-1 and -2, with isoform-1 being the main form in human blood. It possesses insulin-sensitizing, anti-inflammatory, anti-atherogenic, cardio-protective, and oxidative stress-decreasing effects. Omentin's cardiovascular protective actions are caused by the improved endothelial cell survival and function, increased endothelial nitric oxide synthase (eNOS) and nitric oxide (NO) bioavailability, enhanced vascular smooth muscle cells (VSMCs) relaxation with reduced proliferation, decreased inflammation, and suppressed oxidative stress...

OBJECTIVE: The study aims to investigate whether patients with ST-elevation myocardial infarction (STEMI)-related periodontitis will experience any changes in asprosin levels. BACKGROUND: Periodontitis is a common, chronic infection of the periodontium that is epidemiologically associated with cardiovascular disease. Although asprosin, a hormone released from adipose tissue, is a protective role in cardiovascular diseases, its effectiveness in periodontitis is unknown...

Obesity is one of the main risk factors for cardiovascular diseases, type II diabetes, hypertension, and certain cancers. Obesity in women at the reproductive stage adversely affects contraception, fertility, maternal well-being, and the health of their offspring. Being a major protein component in chylomicrons and high-density lipoproteins, apolipoprotein A-IV (apoA-IV) is involved in lipid metabolism, food intake, glucose homeostasis, prevention against atherosclerosis, and platelet aggregation. The goal of the present study is to determine the impact of apoA-IV deficiency on metabolic functions in 129X1/SvJ female mouse strain...

Understanding the complex interactions between metabolism and the immune system ("metaflammation") is crucial for the identification of key immunomodulatory factors as potential therapeutic targets in obesity and in cardiovascular diseases. Cathelicidin antimicrobial peptide (CAMP) is an important factor of innate immunity and is expressed in adipocytes. CAMP, therefore, might play a role as an adipokine in metaflammation and adipose inflammation. TNFα, cell-free nucleic acids (cfDNA), and toll-like receptor (TLR) 9 are components of the innate immune system and are functionally active in adipose tissue...

BACKGROUND: Omentin-1 is a novel adipokine and is associated with chronic inflammation and cardiovascular diseases. However, it remains unclear whether omentin-1 levels are associated with diagnostic significance in elderly patients with heart failure with preserved ejection fraction (HFpEF). This study aimed to investigate the correlation between omentin-1 and HFpEF in Chinese elderly patients. HYPOTHESIS: Omentin-1 may be invovled in HFpEF and there may be a difference of omentin-1 levels between HFpEF and control...
