We showed previously that terbinafine, an allylamine with fungicidal activity, could inhibit angiogenesis by suppressing the endothelial cell proliferation. In the present study, we further showed that terbinafine (0-120 micromol/L) dose dependently inhibited the adhesion and migration of human umbilical vascular endothelial cells (HUVEC). Western blot analysis showed that terbinafine decreased...

Chronic lymphocytic leukemia (CLL) cell migration into lymphoid tissues is an important aspect of the pathobiology of this disease. Here, we investigated the role of ephrin-A4 (EFNA4) in the transendothelial migration (TEM) capacity of CLL and normal B cells through interacting with endothelial EphA2 (erythropoietin-producing hepatocellular carcinoma). CLL cells showed a remarkable impairment i...

Vascular endothelial cells, providing a nonthrombogenic surface to the lumenal aspect of blood vessels, are anchored to matrix adhesion molecules in the subendothelium through their respective receptors belonging to a superfamily of integrins. We analyzed the reactivity of synthetic peptide analogs of adhesive proteins toward human umbilical vein endothelial cells (HUVEC), assaying their detach...

SCOPE Selenium (Se) is incorporated into selenoproteins as selenocysteine, which requires structures in the 3'-untranslated region (3'-UTR) of selenoprotein mRNAs. The functional consequences of a single nucleotide polymorphism (SNP) within the 3'-UTR of the selenoprotein GPX4 gene (GPX4c718t) was assessed in human umbilical vein endothelial cells (HUVECs) and monocytes from human volunteers. ...

High-content screening of kinase inhibitors is important in order to identify biogenesis and function mechanisms of subcellular organelles. Here, we present a human kinome siRNA high-content screen on primary human umbilical vein endothelial cells, that were transfected by electroporation. The data descriptor contains a confocal fluorescence, microscopic image dataset. We also describe an open ...

Objective: Envenomation by heamotoxic snakes constituted a critical health occurrence in the world. Bleeding is the most sever consequence following snake bite with viperid and crothalid snakes. It is believed that the degradation of vascular membrane caused hemorrhage; in contrast, some suggested that direct cytotoxicity has role in endothelial cell disturbances. This study was to evaluate the...

Reactive oxygen species (ROS) superoxide anion (O(2)()) and hydrogen peroxide (H(2)O(2)) produced by activated leukocytes and endothelial cells in sites of inflammation or ischemia cause endothelial barrier dysfunction that may lead to tissue edema. Antioxidant enzymes (AOEs) catalase and superoxide dismutase (SOD) conjugated with antibodies to platelet-endothelial cell adhesion molecule-1 (PEC...

Changes in endothelial cell (EC) phenotype are central to the function of endothelium in inflammation. Although these events mainly occur in the microvasculature, previous studies have predominantly used large-vessel EC. Using enzyme-linked immunosorbent and flow cytometric assays, we compared the responses of human umbilical vein endothelial cells (HUVEC) and dermal microvascular endothelial c...

Homocysteine- (Hcy-) induced endothelial cell apoptosis has been suggested as a cause of Hcy-dependent vascular injury, while the proposed molecular pathways underlying this process are unclear. In this study, we investigated the adverse effects of Hcy on human umbilical vein endothelial cells (HUVEC) and the underlying mechanisms. Our results demonstrated that moderate-dose Hcy treatment induc...

Large for gestational age infants have increased risk of developing the metabolic syndrome and cardiovascular disease in child- and adulthood. The vascular endothelium is a target site in the pathogenesis of many cardiovascular disorders. The matrix metalloproteinases (MMP) are important modulators of the extracellular matrix and serve as markers of these disorders. Here, we asked whether umbil...
