Abstract
Dietary modifications can help prevent many cardiovascular disease (CVD) events. Endothelial progenitor cells (EPCs) actively contribute to cardiovascular system maintenance and could function as surrogate markers for evaluating improvement in cardiovascular health resulting from nutritional interventions. This review summarizes the latest research progress on the impact of food and nutrients on EPCs, drawing on evidence from human, animal, and in vitro studies. Additionally, current trends and challenges faced in the field are highlighted. Findings from studies examining cells as EPCs are generally consistent, demonstrating that a healthy diet, such as the Mediterranean diet or a supervised diet for overweight people, specific foods like olive oil, fruit, vegetables, red wine, tea, chia, and nutraceuticals, and certain nutrients such as polyphenols, unsaturated fats, inorganic nitrate, and vitamins, generally promote higher EPC numbers and enhanced EPC function. Conversely, an unhealthy diet, such as one high in sugar substitutes, salt, or fructose, impairs EPC function. Research on outgrowth EPCs has revealed that various pathways are involved in the modulation effects of food and nutrients. The potential of EPCs as a biomarker for assessing the effectiveness of nutritional interventions in preventing CVDs is immense, while further clarification on definition and characterization of EPCs is required.

Abstract
Treatment with icosapent ethyl 4 g/day, a highly purified and stable ethyl ester of eicosapentaenoic acid (EPA), demonstrated a significant reduction in atherosclerotic cardiovascular disease (ASCVD) events and death in REDUCE-IT. However, analyses of REDUCE-IT and meta-analyses have suggested that this clinical benefit is greater than can be achieved by triglyceride reduction alone. EPA therefore may have additional pleiotropic effects, including anti-inflammatory and anti-aggregatory mechanisms. EPA competes with arachidonic acid for cyclooxygenase and lipoxygenase, producing anti-inflammatory and anti-aggregatory metabolites rather than the more deleterious metabolites associated with arachidonic acid. Changing the EPA:arachidonic acid ratio may shift metabolic status from pro-inflammatory/pro-aggregatory to anti-inflammatory/anti-aggregatory. EPA also has antioxidant effects and increases synthesis of nitric oxide. Incorporation of EPA into phospholipid bilayers influences membrane structure and may help to prevent cardiac arrhythmias. Clinically, this may translate into improved vascular health, including regression of atherosclerotic plaque. Overall, EPA has a range of pleiotropic effects that contribute to a reduction in ASCVD.

Abstract
Background: The endothelium plays an important role in cardiovascular regulation, from blood flow to platelet aggregation, immune cell infiltration and demargination. A dysfunctional endo-thelium leads to the onset and progression of Cardiovascular Disease (CVD). The aging endothelium displays significant alterations in function, such as reduced vasomotor functions and reduced angio-genic capabilities. This could be partly due to elevated levels of oxidative stress and reduced endothe-lial cell turnover. Circulating angiogenic cells, such as Endothelial Progenitor Cells (EPCs) play a significant role in maintaining endothelial health and function, by supporting endothelial cell prolifera-tion, or via incorporation into the vasculature and differentiation into mature endothelial cells. Howev-er, these cells are reduced in number and function with age, which may contribute to the elevated CVD risk in this population. However, lifestyle factors, such as exercise, physical activity obesity, and dietary intake of omega-3 polyunsaturated fatty acids, nitrates, and antioxidants, significantly af-fect the number and function of these circulating angiogenic cells. Conclusion: This review will discuss the effects of advancing age on endothelial health and vascular regenerative capacity, as well as the influence of diet, exercise, and obesity on these cells, the mecha-nistic links and the subsequent impact on cardiovascular health

Docosahexaenoic acid reversed atherosclerotic changes in human endothelial cells induced by palmitic acid in vitro. Cell Biochem Funct 2018; 36:203-211. [PMID: 29653462 DOI: 10.1002/cbf.3332] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Revised: 02/14/2018] [Accepted: 03/08/2018] [Indexed: 12/25/2022]
Abstract
Abnormal activity of atherosclerotic endothelial cells paving luminal surface of blood vessels has been described in many diseases. It has been reported that natural polyunsaturated fatty acids such as docosahexaenoic acid exert therapeutic effects in atherosclerotic condition. Human umbilical vein endothelial cells were treated with 1mM palmitic acid for 48 hours and exposed to 40μM docosahexaenoic acid for the next 24 hours. Real-time polymerase chain reaction analysis was used to measure the expression of PTX3, iNOS, and eNOS. The level of nitric oxide was detected by Griess reagent. The transcription level of genes participating in coagulation and blood pressure was studied by polymerase chain reaction array. Docosahexaenoic acid improved the survival rate by reducing apoptosis rate (P < .05). Compared with that of the group given palmitic acid, attenuation of proinflammatory status was indicated by reduced interleukin-6 (P < .05) and prostaglandin E2 levels. All genes PTX3, iNOS, and eNOS were down-regulated after being exposed to docosahexaenoic acid. Nitric oxide contents were not changed in cells exposed to docosahexaenoic acid. Polymerase chain reaction array confirmed the reduction of LPA, PDGFβ, ITGA2, SERPINE1, and FGA after exposure to docosahexaenoic acid for 24 hours (P < .05). Docosahexaenoic acid had potential to blunt atherosclerotic changes in the modulation of genes controlling blood coagulation, pressure, and platelet function. SIGNIFICANCE OF THE STUDY The current experiment showed that docosahexaenoic acid could reverse atherosclerotic changes in human endothelial cells induced by palmitic acid. The increased levels of interleukin-6 and prostaglandin E2 in atherosclerotic cells were returned to near-to-normal status. Gene expression analysis showed a reduced activity of genes participating in atherosclerotic endothelial cells treated by docosahexaenoic acid. The expression of genes related to cell clotting activity was also similar to that of normal cells.

Abstract
BACKGROUND AND AIMS Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) found in fish oil are postulated to have favourable effects on platelet, endothelial and vascular function. We investigated whether EPA has differential effects on in vivo platelet aggregation and other markers of cardiovascular risk compared to DHA. METHODS AND RESULTS Following a 2 wk run-in taking encapsulated refined olive oil, 48 healthy young men were randomly allocated using a parallel design to receive EPA-rich (3.1 g EPA/d) or DHA-rich (2.9 g DHA/d) triglyceride concentrates or refined olive oil (placebo), for a total supplementary lipid intake of 5 g/d. The specified primary outcome was change in platelet monocyte aggregates (PMA); secondary outcomes were capillary density, augmentation index, digital pulse volume measurements, 24 h ambulatory BP, plasma 8-isoprostanes-F2α. Changes in the proportions of DHA and EPA in erythrocytes and non-esterified fatty acid composition indicated compliance to the intervention. There was no significant treatment effect on PMA (P = 0.382); mean changes (%) (95% CI) were placebo -0.5 (-2.0, 1.04), EPA 0.4 (-0.8, 1.6), DHA 0.3 (-1.5, 2.0). R-QUICKI, an index of insulin sensitivity, was greater following EPA compared to placebo (P < 0.05). No other significant differences were noted. CONCLUSION Neither EPA- nor DHA-rich fish oil supplementation influence platelet-monocyte aggregation or several markers of vascular function after 6 wk in healthy young males. This trial was registered at clinicaltrials.gov as NCT01735357.

Abstract
OBJECTIVES Circulating endothelial progenitor cells (EPCs), which have the ability to differentiate into mature endothelial cells, can elicit angiogenesis, vasculogenesis and vessel repair in cardiac ischemia and vascular injuries caused by endothelial damage. Serum 1,5-anhydro-d-glucitol (1,5-AG), which is a useful clinical marker of postprandial hyperglycemia, eicosapentaenoic acid (EPA), and arachidonic acid (AA) are newly identified risk factors for coronary artery disease (CAD). However, no previous study has reported the associations between EPCs and 1,5-AG, EPA, and AA levels in CAD patients with type 2 diabetes mellitus (DM). METHODS Peripheral EPCs, assessed as CD34+ cells co-expressing CD133 and vascular endothelial growth factor receptor-2, were studied in 76 CAD patients (mean age, 69.2±11.3years) with DM. Serum 1,5-AG, EPA, and AA levels were measured. RESULTS EPC numbers showed a significant association with 1,5-AG and HbA1c (r=0.290; p=0.037 and r=-0.328; p=0.011, respectively). In addition, there were significant associations between EPC numbers and EPA and body mass index (BMI) (r=0.354; p=0.027 and r=-0.402; p=0.002, respectively). In multiple linear regression analysis, HbA1c, BMI, and EPA values had significant associations with EPC numbers (β=-0.316, 95% confidence interval (CI) -0.256 to -0.008, p=0.037; β=-0.413, 95% CI -0.099 to -0.017, p=0.007; and β=0.400, 95% CI 0.004 to 0.002, p=0.010, respectively). CONCLUSIONS EPC number is associated with HbA1c, 1,5-AG, EPA, and BMI values, suggesting that postprandial hyperglycemia and n-3 polyunsaturated fatty acids contribute to EPC recruitment in CAD patients with type 2 DM.

Abstract
Scope High intakes of n-3 fatty acids exert anti-inflammatory effects and cardiovascular protection, but the underlying molecular basis is incompletely defined. By genome-wide analysis we searched for novel effects of docosahexaenoic acid (DHA) on gene expression and pathways in human vascular endothelium under pro-inflammatory conditions. Methods and Results Human umbilical vein endothelial cells were treated with DHA and then stimulated with interleukin(IL)-1β. Total RNA was extracted, and gene expression examined by DNA microarray. DHA alone altered the expression of 188 genes, decreasing 92 and increasing 96. IL-1β changed the expression of 2031 genes, decreasing 997 and increasing 1034. Treatment with DHA before stimulation significantly affected the expression of 116 IL-1β-deregulated genes, counter-regulating the expression of 55 genes among those decreased and of 61 among those increased. Functional and network analyses identified immunological, inflammatory and metabolic pathways as the most affected. Newly identified DHA-regulated genes are involved in stemness, cellular growth, cardiovascular system function and cancer, and included cytochrome p450 4F2(CYP4F2), transforming growth factor(TGF)-β2, Cluster of Differentiation (CD)47, caspase recruitment domain(CARD)11 and phosphodiesterase(PDE)5α. Conclusions Endothelial exposure to DHA regulates novel genes and related pathways. Such unbiased identification should increase our understanding of mechanisms by which n-3 fatty acids affect human diseases.

Abstract
Postprandial dysmetabolism in type 2 diabetes (T2D) is known to impact the progression and evolution of this complex disease process. However, the underlying pathogenetic mechanisms still require full elucidation to provide guidance for disease prevention and treatment. This review focuses on the marked redox changes and inflammatory stimuli provoked by the spike in blood glucose and lipids in T2D individuals after meals. All the causes of exacerbated postprandial oxidative stress in T2D were analyzed, also considering the consequence of enhanced inflammation on vascular damage. Based on this in-depth analysis, current strategies of prevention and pharmacologic management of T2D were critically reexamined with particular emphasis on their potential redox-related rationale.

Abstract
BACKGROUND AND AIMS Recent data suggest that n-3 PUFA exert beneficial effects on endothelial progenitor cell (EPC) biology. We sought to investigate whether these effects might be mediated by enhanced EPC in vitro function and/or in vivo bioavailability. METHODS AND RESULTS CACs and late-outgrowth EPCs were isolated from peripheral blood mononuclear cells obtained from 12 donor buffy-coats. The effect of n-3 PUFA (EPA:DHA = 0.9:1.5; 9 μM EPA plus 15 μM DHA) was tested on CAC/EPC viability, function (tube-formation) and pro-inflammatory molecule expression. Circulating EPC (cells positive for CD34, CD133 and kinase insert domain receptor - KDR cell-surface antigens by flow cytometry) number was evaluated in 20 healthy subjects (10 F/10 M, 32 ± 5 years), randomized to receive 4 mackerel or sardine portions per week for 6 weeks followed by a 6 week free-diet period. N-3 PUFA improved CAC and late-outgrowth EPC viability (p < 0.05) and the capacity to form tube-like structures in CACs (+38%; p < 0.05) and late-outgrowth EPCs (+15%; p < 0.05). ICAM-1 expression was reduced in both CACs (p < 0.05) and late-outgrowth EPCs (p < 0.05) and VCAM-1 in late-outgrowth EPCs (p < 0.005). N-3 PUFA significantly decreased TNF-α and MCP-1 expression in CACs and IL-8, TNF-α and MCP-1 in late-outgrowth EPCs (p < 0.05). Circulating EPC number significantly improved after 6 weeks of a fish-enriched diet (p < 0.01) and returned to baseline levels after a 6 week free-diet period (p < 0.01). Plasma EPA levels were independently and positively associated with EPC levels (p < 0.005). CONCLUSION Our findings support the case of a beneficiary role played by n-3 PUFA in EPC function and bioavailability.

Abstract
BACKGROUND Emerging cellular markers of endothelial damage and repair include endothelial microparticles (EMPs) and endothelial progenitor cells (EPCs), respectively. Effects of long-chain (LC) n-3 (omega-3) polyunsaturated fatty acids (PUFAs) and the influence of genetic background on these markers are not known. OBJECTIVE We investigated effects of fish-oil supplementation on both classical and novel markers of endothelial function in subjects prospectively genotyped for the Asp298 endothelial nitric oxide synthase (eNOS) polymorphism and at moderate risk of cardiovascular disease (CVD). DESIGN A total of 84 subjects with moderate risk of CVD (GG: n = 40; GT/TT: n = 44) completed a randomized, double-blind, placebo-controlled, 8-wk crossover trial of fish-oil supplementation that provided 1.5 g LC n-3 PUFAs/d. Effects of genotype and fish-oil supplementation on the blood lipid profile, inflammatory markers, vascular function (by using peripheral artery tonometry), and numbers of circulating EPCs and EMPs (by using flow cytometry) were assessed. RESULTS There was no significant effect of fish-oil supplementation on blood pressure, plasma lipids, or plasma glucose, although there was a trend (P = 0.069) toward a decrease in the plasma triglyceride concentration after fish-oil supplementation compared with placebo treatment. GT/TT subjects tended to have higher concentrations of total cholesterol and low-density lipoprotein cholesterol, but vascular function was not affected by either treatment or eNOS genotype. Biochemical markers of endothelial function were also unaffected by treatment and eNOS genotype. In contrast, there was a significant effect of fish-oil supplementation on cellular markers of endothelial function. Fish-oil supplementation increased numbers of EPCs and reduced numbers of EMPs relative to those with placebo treatment, which potentially favored the maintenance of endothelial integrity. There was no influence of genotype for any cellular markers of endothelial function, which indicated that effects of fish-oil supplementation were independent of eNOS genotype. CONCLUSION Emerging cellular markers of endothelial damage, integrity, and repair appear to be sensitive to potentially beneficial modification by dietary n-3 PUFAs. This trial was registered at www.controlled-trials.com/isrctn as ISRCTN76272133.

Eicosapentaenoic acid protects against palmitic acid-induced endothelial dysfunction via activation of the AMPK/eNOS pathway. Int J Mol Sci 2014; 15:10334-49. [PMID: 24918290 PMCID: PMC4100154 DOI: 10.3390/ijms150610334] [Citation(s) in RCA: 64] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2014] [Revised: 05/12/2014] [Accepted: 05/22/2014] [Indexed: 02/08/2023] Open
Abstract
Recent studies have shown that free fatty acids are associated with chronic inflammation, which may be involved in vascular injury. The intake of eicosapentaenoic acid (EPA) can decrease cardiovascular disease risks, but the protective mechanisms of EPA on endothelial cells remain unclear. In this study, primary human umbilical vein endothelial cells (HUVECs) treated with palmitic acid (PA) were used to explore the protective effects of EPA. The results revealed that EPA attenuated PA-induced cell death and activation of apoptosis-related proteins, such as caspase-3, p53 and Bax. Additionally, EPA reduced the PA-induced increase in the generation of reactive oxygen species, the activation of NADPH oxidase, and the upregulation of inducible nitric oxide synthase (iNOS). EPA also restored the PA-mediated reduction of endothelial nitric oxide synthase (eNOS) and AMP-activated protein kinase (AMPK) phosphorylation. Using AMPK siRNA and the specific inhibitor compound C, we found that EPA restored the PA-mediated inhibitions of eNOS and AKT activities via activation of AMPK. Furthermore, the NF-κB signals that are mediated by p38 mitogen-activated protein kinase (MAPK) were involved in protective effects of EPA. In summary, these results provide new insight into the possible molecular mechanisms by which EPA protects against atherogenesis via the AMPK/eNOS-related pathway.
