BACKGROUND AND AIMS: Several studies have demonstrated that both native glucagon-like peptide-1 (GLP-1) and GLP-1 receptor agonists suppress the progression of atherosclerosis in animal models. METHODS: We investigated whether liraglutide, a GLP-1 analogue, could prevent the development of atherosclerosis in apolipoprotein E knockout mice (ApoE(-/-)) on a high-fat diet. We also examined the influence of liraglutide on angiotensin II-induced proliferation of rat vascular smooth muscle cells (VSMCs) via enhancement of AMP-activated protein kinase (AMPK) signaling and regulation of cell cycle progression...

The role of estrogen receptor alpha (ERα) signaling in the vasculature of females has been described under different experimental conditions and our group recently reported that lack of endothelial ERα in female mice fed a Western diet (WD) results in amelioration of vascular stiffness. Conversely, the role of ERα in the male vasculature in this setting has not been explored. In conditions of over-nutrition and insulin resistance, augmented arterial stiffness, endothelial dysfunction and arterial remodeling contribute to the development of cardiovascular disease...

Background: The consumption of a Mediterranean diet (MedDiet) is associated with a lower risk of cardiovascular disease. However, its impact on blood pressure and endothelial function is not clear.Objective: We sought to determine the effects of adhering to the consumption of a MedDiet for 6 mo on blood pressure and endothelial function in older, healthy Australians.Design: A total of 166 men and women aged >64 y were allocated via minimization to consume either a MedDiet (n = 85) or their habitual diet (HabDiet; control: n = 81) for 6 mo...

Similar to neoplastic tissues, growth and development of adipose tissue are thought to be angiogenesis-dependent. Since visceral adipose tissue (VAT) is associated with development and progression of nonalcoholic fatty liver disease (NAFLD), we hypothesized that angiogenesis inhibition would attenuate obesity-induced NAFLD. We fed C57BL/6J mice a low-fat diet (LFD, chow 10% kcal fat), a high-fat diet (HFD, 45% kcal fat) or HFD supplemented with the lemon-balm extract ALS-L1023 (HFD-ALS) for 15 weeks. ALS-L1023 reduced endothelial cell-tube formation in vitro...

BACKGROUND: Disturbances in coronary microcirculatory function, such as the endothelial glycocalyx, are early hallmarks in the development of obesity and insulin resistance. Accordingly, in the present study myocardial microcirculatory perfusion during rest and stress was assessed following metformin or sulodexide therapy in a rat model of diet-induced obesity. Additionally, the effect of degradation of the glycocalyx on myocardial perfusion was assessed in chow-fed rats. METHODS: Rats were fed a high fat diet (HFD) for 8 weeks and were divided into a group without therapy, and groups that received the anti-diabetic drug metformin or the glycocalyx-stabilizing drug sulodexide in their drinking water during the last 4 weeks of the feeding period...

Low-density lipoprotein receptor-related protein 1 (LRP1) regulates lipid and glucose metabolism in liver and adipose tissue. It is also involved in central nervous system regulation of food intake and leptin signalling. Here we demonstrate that endothelial Lrp1 regulates systemic energy homeostasis. Mice with endothelial-specific Lrp1 deletion display improved glucose sensitivity and lipid profiles combined with increased oxygen consumption during high-fat-diet-induced obesity. We show that the intracellular domain of Lrp1 interacts with the nuclear receptor Pparγ, a central regulator of lipid and glucose metabolism, acting as its transcriptional co-activator in endothelial cells...

BACKGROUND: While obesity is a leading risk factor for preeclampsia, the mechanisms whereby obese women are more susceptible to pregnancy-induced hypertension are unclear. As high-fat diet (HFD) is an important contributor to the development of obesity, we tested the hypothesis that pregnant rats on HFD have hypertension and endothelial dysfunction due to reduced nitric oxide synthase (NOS). METHODS: Twelve-week-old Sprague-Dawley female rats were fed normal diet (ND, 13% fat kcal) or HFD (40% fat kcal) for 9 weeks...

A soluble form of endoglin (sEng) released into the circulation was suggested to be a direct inducer of endothelial dysfunction, inflammation and contributed to the development of hypertension by interfering with TGF-β signaling in cardiovascular pathologies. In the present study, we assessed the hypothesis that high sEng level-induced hypertension via a possible sEng interference with TGF-β signaling pathways may result in inflammatory, structural or fibrotic changes in hearts of Sol-Eng+ mice (mice with high levels of soluble endoglin) fed either chow or high-fat diet...

REVIEW
Junji Terao
Nowadays dietary flavonoids attract much attention in the prevention of chronic diseases. Epidemiological and intervention studies strongly suggest that flavonoid intake has beneficial effects on vascular health. It is unlikely that flavonoids act as direct antioxidants, although oxidative stress profoundly contributes to vascular impairment leading to cardiovascular diseases. Instead, flavonoids may exert their function by tuning the cellular redox state to an adaptive response or tolerable stress. However, the optimum intake of flavonoids from supplements or diet has not been clarified yet, because a number of exogenous and endogenous factors modulating their bioavailability affect their vascular function...

Surgical repair of caustic esophageal injuries with autologous gastrointestinal segments is often associated with dysmotility, dysphagia, and donor site morbidity and therefore alternative graft options are needed. Bi-layer silk fibroin (BLSF) scaffolds were assessed for their ability to support functional restoration of damaged esophageal tissues in a rat model of onlay esophagoplasty. Transient exposure of isolated esophageal segments with 40% NaOH led to corrosive esophagitis and a 91% reduction in the luminal cross-sectional area of damaged sites...

Impaired PPARγ activity in endothelial cells causes oxidative stress and endothelial dysfunction which causes a predisposition to hypertension, but the identity of key PPARγ target genes that protect the endothelium remain unclear. Retinol-binding protein 7 (RBP7) is a PPARγ target gene that is essentially endothelium specific. Whereas RBP7-deficient mice exhibit normal endothelial function at baseline, they exhibit severe endothelial dysfunction in response to cardiovascular stressors, including high-fat diet and subpressor angiotensin II...

Background -The angiogenic function of endothelial cells is regulated by numerous mechanisms but the impact of long noncoding RNAs (lncRNAs) has hardly been studied. We set out to identify novel and functionally important endothelial lncRNAs. Methods -Epigenetically controlled lncRNAs in human umbilical vein endothelial cells (HUVEC) were searched by exon-array analysis after knockdown of the histone demethylase JARID1B. Molecular mechanisms were investigated by RNA Pulldown and Immunoprecipitation, Mass spectrometry, Micro-array, several knockdown approaches, CRIPSR-Cas9, Assay for Transposase-Accessible Chromatin-Sequencing and chromatin immunoprecipitation in HUVEC...

This study aims to identify both endothelia-specific/enriched and senescence-associated miRNAs as well as their functions. The rats were fed on high-fat diet to establish a hyperlipidemic model, which showed an increase in plasma lipids and acceleration in endothelial senescence and endothelial dysfunction, accompanied by alterations in 7 endothelia-specific/enriched and senescence-associated miRNAs. Among the 7 selected miRNAs, miR-21-5p and miR-203a-3p were significantly up-regulated in a human umbilical vein endothelial cells (HUVECs) senescent model induced by ox-LDL, consistent with their changes in the hyperlipidemic rats...

The antioxidant function of edible flowers have attracted increasing interest. However, information is lacking on the impact of edible flowers on oxidative injury including hypoxia-re-oxygenation and hyperlipidemia. The antioxidant activities of aqueous extracts from 12 Chinese edible flowers were assessed in four different antioxidant models, including total antioxidant capacity (TAC), oxygen radical absorbance capacity (ORAC), scavenging hydroxyl radical capacity (SHRC) and scavenging superoxide anion radical capacity (SSARC)...

In response to salt loading, Na(+) and Cl(-) accumulate in the skin in excess of water, stimulating skin lymphangiogenesis via activation of the mononuclear phagocyte system cell-derived vascular endothelial growth factor-C-vascular endothelial growth factor type 3 receptor signaling pathway. Inhibition of this pathway results in salt-sensitive hypertension. Sunitinib is an antiangiogenic, anticancer agent that blocks all 3 vascular endothelial growth factor receptors and increases blood pressure. We explored the salt dependency of sunitinib-induced hypertension and whether impairment of skin lymphangiogenesis is an underlying mechanism...

Our recent studies have indicated that nucleolin, as a multifunctional RNA-binding protein, exerts protective effects in the myocardial cells and endothelial cells under the condition of oxidative stress. However, the function of nucleolin and its potential mechanism in macrophage-derived foam cell formation remain largely unexplored. ApoE-/- mice were fed with a high-fat diet (HFD) for 10-24 weeks. Protein expression was measured by western blotting or immunofluorescence, and gene expression at the mRNA level was detected by qRT-PCR...

Obesity promotes infiltration of inflammatory cells into various tissues, leading to parenchymal and stromal cell interaction and development of cellular and organ dysfunction. Liver sinusoidal endothelial cells (LSECs) are the first cells that contact portal blood cells and substances in the liver, but their functions in the development of obesity-associated glucose metabolism remain unclear. Here, we find that LSECs are involved in obesity-associated accumulation of myeloid cells via VLA-4-dependent cell-cell adhesion...

The purpose of the present study is to explore the effects of a lipid-lowering drug atorvastatin, a three-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor, in the treatment of erectile dysfunction (ED) in a rat model of atherosclerosis (AS) and the possible mechanisms underneath. A high-cholesterol diet was administrated to Sprague-Dawley rats in an attempt to induce an ASED model, which was later confirmed by abdominal aorta histopathology and erectile function evaluation. ASED rats were further assigned to non-treatment group, atorvastatin low-dose treatment group (5 mg kg(-1)  day(-1) ), high-dose group (10 mg kg(-1)  day(-1) ) and sildenafil (1...
