Hepatocyte growth factor (HGF)/scatter factor (SF) is a cytokine exerting a wide range of biological functions on many cell types, including vascular endothelial cells. HGF/SF increases migration, motility, and dissociation of human umbilical vascular endothelial cells (HUVECs). This study demonstrated that such action of HGF/SF on HUVECs was achieved by regulation of the endothelial cell-speci...

Background Myricetin has been shown to possess potential antiangiogenic effects in endothelial cells. However, the underlying mechanisms are not fully understood. Therefore, we evaluated its antiangiogenic effects in human umbilical vascular endothelial cells (HUVECs). Methods HUVECs were cultured in endothelial cell growth medium-2 to induce proliferation and angiogenesis and treated with di...

Angiotensin converting enzyme inhibitors (ACE-I) are able to reduce the formation of the potent vasoconstrictor endothelin-1 and increase nitric oxide bioavailability in human vascular endothelial cells (HUVECs). We tested the effects of two sulfhydryl-containing ACE-I, zofenoprilat, and captopril, and two nonsulfhydryl containing ACE-I, enalaprilat and lisinopril, on endothelin-1/nitric oxide ...

Morphology and changes in gene expression of vascular endothelium are mainly due to shear stress and inflammation. Cell phenotype modulation has been clearly demonstrated to be controlled by small noncoding micro-RNAs (miRNAs). This study focused on the effect of laminar shear stress (LSS) on human endothelial cells (HUVECs), with an emphasis on the role of miRNA-126 (miR-126). Exposure of HUVE...

BACKGROUND African American ethnicity is an independent risk factor for exaggerated oxidative stress, which is related to inflammation, hypertension, and cardiovascular disease. Recently, we reported that in vitro oxidative stress and inflammation levels differ between African American and Caucasian human umbilical vein endothelial cells (HUVECs), African American HUVECs having higher levels of...

BACKGROUND AND OBJECTIVES   Vascular endothelium injury caused by reactive oxygen species (ROS) plays an initial role in the pathogenesis of atherosclerosis. Resveratrol, a natural polyphenolic compound, is well known to possess a variety of cardioprotective activities. In this study we first investigated the effects of resveratrol against apoptosis of human umbilical vein endothelial cells (HU...

Hesperetin has been shown to possess a potential anti-angiogenic effect, including vascular formation by endothelial cells. However, the mechanisms underlying the potential anti-angiogenic activity of hesperetin are not fully understood. In the present study, we evaluated whether hesperetin has anti-angiogenic effects in human umbilical vascular endothelial cells (HUVECs). HUVECs were treated w...

The aim of this study was to investigate the inhibition capacity of telmisartan to endothelial inflammation induced by homocysteine (Hcy) and discuss the proposed mechanism in vitro. Human umbilical vein endothelial cells (HUVECs) were prepared by collagenase digestion and cultured in vitro. An increase in monocyte chemoattractant protein-1 (MCP-1) and vascular cell adhesion molecule-1 (VCAM-1)...

Atherosclerosis is well established as a chronic inflammatory disorder, and Chlamydia pneumoniae is considered to be a risk factor for atherosclerotic development. Endothelial dysfunction, caused by oxidized low‐density lipoprotein (ox‐LDL) is an early atherosclerotic marker. However, the effect of C. pneumoniae on lipid metabolism in vascular endothelial cells is yet to be elucidated. The aim ...

Objective: Advanced age is associated with impaired angiogenesis in part because of mitochondrial dysfunction. We have recently reported that leonurine exerts protective effects in neuron via regulation of mitochondrial function. The aim of this study was to explore whether leonurine is able to attenuate mitochondrial dysfunction and to enhance angiogenesis in old rats with hindlimb ischemia. M...
