Abstract
BACKGROUND Cardiovascular events and poor quality of life are frequently observed in patients with coronary slow flow phenomenon (CSFP). This trial evaluated the effect of nano-curcumin supplement containing curcuminoids, as multifunctional nutraceuticals, on angina status, and some traditional and novel cardiovascular risk factors in overweight or obese patients with CSFP. METHODS In this double-blind, randomized, placebo-controlled clinical trial, 42 overweight or obese patients with CSFP received either 80 mg/day of nano-curcumin or placebo for 12 weeks. Seattle angina questionnaire (SAQ) as a clinical measure of angina status, circulating endocan, adropin, homocysteine, lipid profile, and the novel scores of visceral adiposity index (VAI) and waist-triglyceride index (WTI) were assessed before and after the intervention. The independent samples t-test, Mann-Whitney test, analysis of covariance, Chi-square, and Fisher's exact tests were used where appropriate. RESULTS All domains of SAQ including physical limitation, angina stability, angina frequency-severity, treatment satisfaction, and disease perception and quality of life improved significantly in the nano-curcumin compared with the placebo group. No significant changes were observed in serum endocan, adropin, and homocysteine following the intervention. Triglycerides, triglyceride/high-density lipoprotein cholesterol ratio, WTI and VAI values improved significantly only within the nano-curcumin group. CONCLUSIONS Supplementation with 80 mg/day nano-curcumin (containing curcuminoids) for 12 weeks significantly improved clinically important disease-specific aspects of health in patients with CSFP. Some traditional and novel cardiovascular risk factors improved significantly only compared with the baseline values, which need further investigation. TRIAL REGISTRATION This study was approved by the Ethics Committee of Tehran University of Medical Sciences (IR.TUMS.VCR.REC.1398.794). The study protocol was registered at Iranian Registry of Clinical Trials by IRCT20131125015536N8 registration ID at 19.06.2019.

Abstract
Atherosclerosis, a multifaceted and persistent inflammatory condition, significantly contributes to the progression of cardiocerebrovascular disorders, such as myocardial infarctions and cerebrovascular accidents. It involves the accumulation of cholesterol, fatty deposits, calcium and cellular debris in the walls of arteries, leading to the formation of plaques. Our aim is to investigate the potential of sinomenine to counteract atherosclerosis in mice lacking Apolipoprotein E (ApoE-/-) Mice. We employed the high-fat diet-induced method to induce atherosclerosis in ApoE-/- mice, and the mice were treated with sinomenine (5, 10, and 15 mg/kg) and simvastatin (0.5 mg/kg) for 12 weeks. Body weight, water intake, and food intake were assessed. Lipid parameters, oxidative stress, inflammatory cytokines, and mRNA levels were estimated. Sinomenine treatment remarkably (P < 0.001) suppressed body weight, along with food and water intake. Sinomenine altered the levels of total cholesterol (TC), high-density lipoprotein (HDL), triglyceride (TG), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL), which were modulated in the atherosclerosis group. Sinomenine treatment also altered the levels of oxidative stress parameters such as glutathione peroxidase (GPx), catalase (CAT), malonaldehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH). In addition, it modulated cardiac parameters like C-reactive protein (CRP), endothelin-1 (ET-1), thromboxane B2 (TXB2), nitric oxide (NO), cardiac troponin I (cTnI), lactate dehydrogenase (LDH), and creatinine kinase isoenzymes (CK-MB). Inflammatory cytokines interleukin (IL)-1α, IL-1β, TNF-α, IL-6, and IL-10 were also affected. Sinomenine further suppressed the mRNA expression of IL-6, IL-17, IL-10, tumor necrosis factor-α (TNF-α), Il-1β, monocyte chemoattractant protein-1 (MCP-1), MCP-2, MCP-3, transforming Growth Factor-1β (TGF-1β), vascular cell adhesion molecule 1 (VCAM-1), and intercellular adhesion molecule-1 (ICAM-1). The results suggest that sinomenine remarkably suppressed the development of atherosclerosis in the early stage.

Elevated Circulating Endocan Levels Are Associated with Increased Levels of Endothelial and Inflammation Factors in Postprandial Lipemia. J Clin Med 2023; 12:jcm12041267. [PMID: 36835804 PMCID: PMC9966245 DOI: 10.3390/jcm12041267] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 01/16/2023] [Accepted: 02/01/2023] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Postprandial lipemia (PPL) causes endothelial dysfunction by causing endothelial damage to lipoproteins that remain rich in triglycerides. Endocan is a proteoglycan with increased tissue expression, endothelial activation, and neovascularization. The aim of the study was to examine circulating endocan levels in PPL subjects by considering the degree of PPL response according to a high-fat test meal. The other aim was to determine the association between endocan levels and endothelial and inflammatory factors. METHOD Fifty-four hyperlipidemic subjects and 28 normolipidemic subjects consumed the high-fat meal. Endocan, sICAM-1, sVCAM-1, and VEGFA as endothelial factors and IL-6 and LFA-1α as inflammatory factors were evaluated. RESULTS Fasting serum endocan, VEGFA, sICAM-1, sVCAM-1 IL-6, and LFA-1α levels were increased in the PPL group compared to the control group. The PPL group was divided into tertiles based on mean AUC levels. Endocan levels in tertile 3 were at the highest and were increased significantly compared to tertiles 1 and 2. AUC and endocan levels were positively correlated with other endothelial and inflammation factors. ROC analysis showed endocan levels to be one of the highest values. CONCLUSIONS Circulating endocan is seen at significantly higher levels and independently associated with endothelial and inflammatory factors in postprandial lipemia and dyslipidemia.

Abstract
Cerebral small vessel disease (CSVD) poses a serious socio-economic burden due to its high prevalence and severe impact on the quality of life of elderly patients. Pathological changes in CSVD mainly influence small cerebral arteries, microarteries, capillaries, and small veins, which are usually caused by multiple vascular risk factors. CSVD is often identified on brain magnetic resonance imaging (MRI) by recent small subcortical infarcts, white matter hyperintensities, lacune, cerebral microbleeds (CMBs), enlarged perivascular spaces (ePVSs), and brain atrophy. Endothelial cell (EC) dysfunction is earlier than clinical symptoms. Immune activation, inflammation, and oxidative stress may be potential mechanisms of EC injury. ECs of the blood–brain–barrier (BBB) are the most important part of the neurovascular unit (NVU) that ensures constant blood flow to the brain. Impaired cerebral vascular autoregulation and disrupted BBB cause cumulative brain damage. This review will focus on the role of EC injury in CSVD. Furthermore, several specific biomarkers will be discussed, which may be useful for us to assess the endothelial dysfunction and explore new therapeutic directions.

Abstract
Statins have been reported to suppress vascular remodeling in rats with spontaneous hypertension. However, the possible effects of the statin pitavastatin on hypertension-induced endothelial inflammation and injury remain to be fully elucidated. The present study aimed to evaluate the effects of pitavastatin on HUVEC injury and inflammation. HUVECs were exposed to angiotensin (Ang) II with or without pitavastatin co-treatment, after which MAPK7 expression was detected via reverse transcription-quantitative PCR and western blotting. MAPK7 expression was additionally silenced in HUVECs via transfection with short hairpin RNA, followed by Ang II treatment with or without pitavastatin. Cell viability, inflammation, reactive oxygen species (ROS) production, nitric oxide (NO) production and cell apoptosis were then measured by using Cell Conting Kit-8, ELISA, commercial corresponding kits and TUNEL staining, respectively. Western blotting was also used to determine the protein expression of endothelial NO synthase and endothelin 1, and the proteins involved in apoptosis. Results of the present study demonstrated that the expression levels of MAPK7 in Ang II-induced endothelial cells were decreased, which was reversed following treatment with pitavastatin. Pitavastatin reversed the Ang II-induced reduction in cell viability and reversed the Ang II-induced increase in inflammatory factor and ROS levels and apoptosis in HUVECs by activating MAPK7. Treatment with pitavastatin also increased the production of NO in addition to increasing the expression of endothelial NO synthase and endothelin-1 in Ang II-induced HUVECs through MAPK7 activation. Collectively, results from the present study demonstrated that treatment with pitavastatin preserves MAPK7 expression to alleviate Ang II-induced vascular endothelial cell inflammation and injury. Therefore, findings of the present study may help to elucidate the mechanisms underlying the effects of pitavastatin on vascular endothelial cell inflammation and injury.

Abstract
The review analyzes the role of assessing the state of the endothelium in the onset and progression of cardiovascular diseases, stratification of their risks, since endothelial dysfunction (ED) is a crucial predictor of this pathologies. In this regard, this paper presents the modern understanding of the methods for assessing ED, presents the advantages and disadvantages of various techniques. Despite the fact that flow-mediated dilation is widely used as a classical method for studying endothelial function, this technique depends on the physiological state of sensory nerves and calcium-activated potassium channels, cardiac output. This review focuses on new biomarkers for ED such as endothelial microparticles, endoglin and endocan, and discusses the relevance of the criteria for their use in clinical practice. Based on current scientific advances, the authors concluded that among these three newest biomarkers, today, endocan can be considered a more informative and reliable cellular marker of ED. Moreover, the authors have shown that when measured separately, many of the studied classical circulating biomarkers do not provide reliable information about the state of the endothelium, since the endothelial function has a complex physiological nature which therefore raises the question of the advisability of considering a combination of classical and new biomarkers for improving the assessment of the endothelial state.

Abstract
Atherosclerosis is a chronic vascular inflammatory disease, and is associated with oxidative stress and endothelial dysfunction. Homocysteine (HCY) can cause damage to endothelial cells via the enhancement of the endoplasmic reticulum stress (ERS) pathway. Propofol has a protective effect on endothelial injury and can suppress inflammation and oxidation. The purpose of the present study was to investigate the protective effect of propofol on HCY-induced inflammation and apoptosis of human umbilical vein endothelial cells (HUVECs). HCY was used to establish the endothelial injury model. Cell Counting Kit-8 assays and flow cytometry were used to detect cell viability and apoptosis, respectively. Then, ELISA was performed to examine the expression levels of inflammatory cytokines, and the expression levels of proteins related to inflammation, apoptosis and ERS were determined via western blotting. Results showed that propofol increased cell viability, suppressed NF-κB signaling pathway activation and decreased the expression levels of inflammatory factors in HUVECs induced by HCY. Moreover, propofol could inhibit the expression of proteins involved in ERS, including ER chaperone BiP (Bip), C/EBP-homologous protein, protein kinase R-like ER kinase and inositol-requiring 1α, and reduce cell apoptosis of HCY-induced HUVECs. However, the overexpression of Bip could reactivate ERS and the NF-κB signaling pathway, as well as promote inflammation and cell apoptosis, when compared with HCY-treated groups. In conclusion, propofol can ameliorate inflammation and cell apoptosis of HUVECs induced by HCY via inhibiting ERS, which may provide a novel insight into the treatment of atherosclerosis.

Abstract
Theaflavin (TF) in black tea has been shown to have significant antioxidant and anti-inflammatory capacity; however, the effects and the underlying mechanism of TF on atherosclerosis (AS) remain unclear. Herein, we investigated the effects and the potential mechanism of TF on AS progression in vivo and in vitro. ApoE-/- mice were administrated with high fat diet (HFD) or HFD + TF (5 or 10 mg, i.g.) for 12 weeks. The results indicated that TF administration effectively decreases the serum lipid levels and the production of MDA in HFD-fed mice. Meanwhile, TF promotes the activities of antioxidant enzymes (SOD, CAT, and GSH-Px) and inhibits the formation of atherosclerotic plaque and the process of histological alterations in the aorta. In vitro, TF pretreatment could protect against cholesterol-induced oxidative injuries in HUVEC cells, decreasing the level of ROS and MDA, maintaining the activities of antioxidant enzymes. Further study revealed that TF upregulates Nrf2/HO-1 signaling pathway in vascular endothelial cells. Moreover, TF increases the level of microRNA-24 (miR-24), and miR-24 inhibition markedly compromises TF-induced Nrf2 activation and protective effects. In conclusion, the present study indicated that theaflavins may achieve the anti-atherosclerotic effect via activating miR-24-mediated Nrf2/HO-1 signaling pathway.

Abstract
The role of Hsa_circ_0001445 in oxidation Low Lipoprotein (ox-LDL) induced HUVEC inflammatory damage remains poorly characterized. The present study investigated the performance of the circRNA Hsa_circ_0001445 on ox-LDL-induced HUVEC inflammatory damage. ox-LDL was employed to treat HUVECs and the expression of Hsa_circ_0001445 in cells were detected by qRT-PCR. Then, the overexpression plasmid of circ_0001445 was transfected into HUVECs. The Cell Counting Kit-8 assay was performed to detect cell viability, and the expression of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-6 in treatment cells were measured using ELISAs. Furthermore, the oxidative stress kit was used to detect the levels of malondialdehyde, superoxide dismutase and glutathione peroxidase in treatment cells. Flow cytometry assay was applied to measure cell apoptosis, and the expressions of apoptosis-related protein were measured by western blot. The luciferase reporter assay was applied to confirm the target binding between Hsa_circ_0001445 and micro-RNA-640 (miRNA-640). Next, miRNA-640 mimic was transfected into ox-LDL-induced HUVECs, and then cell proliferation, expression level of inflammatory factors, oxidative stress and apoptosis level in treatment cells were assessed, with the expression of related proteins measured. The results revealed that the expression of Hsa_circ_0001445 was obviously downregulated in ox-LDL-induced HUVECs. Overexpression of Hsa_circ_0001445 promoted cell proliferation, inhibited ox-LDL-induced HUVEC inflammatory response, downregulate the expression of TNF-α, IL-1β and IL-16, overexpression of Hsa_circ_0001445 inhibited cell apoptosis. miRNA-640 was confirmed as a direct target of Hsa_circ_0001445, and miRNA-640 mimic reversed the effects of Hsa_circ_0001445 overexpression on ox-LDL-induced HUVECs. Our findings concluded that Hsa_circ_0001445 inhibits ox-LDL-induced HUVEC inflammation, oxidative stress and apoptosis by regulating miRNA-640.

Abstract
The vascular endothelium is a dynamic, functionally complex organ, modulating multiple biological processes, including vascular tone and permeability, inflammatory responses, thrombosis, and angiogenesis. Endothelial dysfunction is a threat to the integrity of the vascular system, and it is pivotal in the pathogenesis of atherosclerosis and cardiovascular disease. Reduced nitric oxide (NO) bioavailability is a hallmark of chronic kidney disease (CKD), with this disturbance being almost universal in patients who reach the most advanced phase of CKD, end-stage kidney disease (ESKD). Low NO bioavailability in CKD depends on several mechanisms affecting the expression and the activity of endothelial NO synthase (eNOS). Accumulation of endogenous inhibitors of eNOS, inflammation and oxidative stress, advanced glycosylation products (AGEs), bone mineral balance disorders encompassing hyperphosphatemia, high levels of the phosphaturic hormone fibroblast growth factor 23 (FGF23), and low levels of the active form of vitamin D (1,25 vitamin D) and the anti-ageing vasculoprotective factor Klotho all impinge upon NO bioavailability and are critical to endothelial dysfunction in CKD. Wide-ranging multivariate interventions are needed to counter endothelial dysfunction in CKD, an alteration triggering arterial disease and cardiovascular complications in this high-risk population.

Abstract
Endothelial dysfunction is one of the earliest indicators of cardiovascular (CV) dysfunction, and its evaluation would be of considerable importance to stratify CV risk of many diseases and to assess the efficacy of atheroprotective treatments. Flow-mediated dilation is the most widely used method to study endothelial function. However, it is operator-dependent and can be influenced by physiological variations. Circulating biomarkers are a promising alternative. Due to the complexity of endothelial function, many of the biomarkers studied do not provide consistent information about the endothelium when measured alone. New circulating markers are being explored and some of them are thought to be suitable for the clinical setting. In this review, we focus on novel biomarkers of endothelial dysfunction, particularly endothelial microparticles, endocan, and endoglin, and discuss whether they fulfill the criteria to be applied in clinical practice.

Abstract
Objective This study investigated changes in urotensin-II (U-II) and endocan levels which can be used as an early biological marker of endothelial injury in the episode and remission phases of bipolar affective disorder (BAD). Methods We compared endocan and U-II levels, which has been shown to be closely associated with neurotransmitter systems in addition to continuity of endothelial structure and inflammatory response, in patients with BAD in remission for at least one year (n=42) and in patients still in manic or depressive episodes (n=16) with healthy controls (n=30). Results Both endocan and U-II levels were significantly higher in the bipolar patients than in the controls. Endocan and U-II levels were also significantly correlated with one another (p=0.000, r=0.833). Both endocan (p=0.000) and U-II levels (p=0.000) were significantly higher in the bipolar attack group compared to the subjects in remission, and in the remission group compared to the controls. Conclusion In this study we determined significantly higher endocan and U-II levels in BAD compared to the controls, while serum endocan and U-II levels of patients undergoing attacks were also significantly higher than those of the controls and also those of patients in remission.

Abstract
Endothelial dysfunction and monocyte adhesion to vascular endothelial cells are two critical steps in atherosclerosis development, and emerging evidence suggests that protein sialylation is involved in these processes. However, the mechanism underlying this phenomenon remains incompletely elucidated. In this study, we demonstrated that treatment with the proinflammatory cytokine TNF-α disrupted vascular endothelial cell-cell tight junctions and promoted monocyte endothelial cell adhesion. Western blotting and Sambucus nigra lectin (SNA) blotting analyses revealed that TNF-α treatment decreased α-2, 6-sialic acid transferase 1 (ST6Gal-I) levels and downregulated VE-Cadherin α-2, 6 sialylation. Further analysis demonstrated that TNF-α treatment upregulated β-site amyloid precursor protein enzyme 1 (BACE1) expression, thus resulting in sequential ST6Gal-I proteolytic degradation. Furthermore, our results revealed that PKC signaling cascades were involved in TNF-α-induced BACE1 upregulation. Together, these results indicated that the proinflammatory cytokine TNF-α impairs endothelial tight junctions and promotes monocyte-endothelial cell adhesion by upregulating BACE1 expression through activating PKC signaling and sequentially cleaving ST6Gal-I. Thus, inhibition of BACE1 expression may be a new approach for treating atherosclerosis.
