Recent experimental and human studies have shown that hyperuricemia is associated with hypertension, systemic inflammation, and cardiovascular disease mediated by endothelial dysfunction and pathologic vascular remodeling. Elevated levels of C-reactive protein (CRP) have emerged as one of the most powerful independent predictors of cardiovascular disease. In addition to being a marker of inflam...

Previous studies showed that several members of the S100A family are involved in neovascularization and tumor development. This study checked whether low concentrations of S100A8 or S100A9 has any effect on the behaviour of vascular endothelial cells. A human umbilical vascular endothelial cell (HUVEC) line was used to measure vascular endothelial cell bioactivity related to angiogenesis, such ...

Cytokine release from inflammatory (CD14(+)) cells is reduced after repeated stimulation with lipopolysaccharide (LPS; LPS tolerance). However, it is not known whether LPS tolerance can be induced in CD14(-) cells. The aim of the present study was to determine whether endothelial cells [human umbilical vein endothelial cells (HUVEC)] could be rendered tolerant to LPS with respect to LPS-induced...

This paper presents a microfluidic model for studying the sequential steps of the cancer extravasation process, in which cancer cells exit capillaries and enter organs. We demonstrate the functionality of this model by co-culturing and observing the adhesion of SK-Mel-28 (Malignant Melanoma) cells to a Human Umbilical Vein Endothelial Cell (HUVEC) monolayer, followed by their migration through ...

Abstract Background As a large capillary network, the human placenta plays an important role throughout pregnancy. Placental vascular development is complex and delicate involves many types of placental cells, such as trophoblasts, mesenchymal stem cells. There has been no systematic, comparative study on roles these two groups cells whole tissue in angiogenesis. In this study, primary cytotrop...

Background: Atherosclerosis is a chronic inflammation that interferes with blood arteries functions due to the accumulation of low density lipids and cholesterol. Objective: To investigate the effect of aqueous extract and saponin fraction of Tribulus terrestris L. (TT) on the proteome and expression of intracellular adhesion molecule-1 (ICAM-1), vascu...

We examined whether the presence of the cell cortex might explain, in part, why previous studies using atomic force microscopy (AFM) to measure cell modulus (E) gave higher values with sharp tips than for larger spherical tips. We confirmed these AFM findings in human umbilical vein endothelial cells (HUVEC) and Schlemm's canal (SC) endothelial cells with AFM indentation ≤ 400 nm, two cell type...

BACKGROUND The presence of anti-endothelial cell antibodies and pathogenic T cells may reflect an autoimmune component in the pathogenesis of emphysema. Whether immune modulatory strategies can protect against the development of emphysema is not known. METHODS Sprague Dawley rats were immunized with human umbilical vein endothelial cells (HUVEC) to induce autoimmune emphysema and treated with...

Cilengitide is a high-affinity cyclic pentapeptdic alphaV integrin antagonist previously reported to suppress angiogenesis by inducing anoikis of endothelial cells adhering through alphaVbeta3/alphaVbeta5 integrins. Angiogenic endothelial cells express multiple integrins, in particular those of the beta1 family, and little is known on the effect of cilengitide on endothelial cells expressing al...

BACKGROUND Histamine is established as a potent inflammatory mediator and it is known to increased endothelial permeability by promoting gap formation between endothelial cells. Previous studies have shown that aqueous extract of Bixa orellana leaves (AEBO) exhibits antihistamine activity in vivo, yet the mechanism of its action on endothelial barrier function remains unclear. Therefore, the cu...
