BACKGROUND Hyperglycemia has been confirmed to damage endothelial function of vascular and microvascular. The regulation of zinc finger E-box binding protein 2 (ZEB2) on vascular endothelial cells (VECs) is reported rarely. Our study investigates the role of ZEB2 on the apoptosis of VECs induced by high glucose through MAPK pathway. MATERIAL AND METHODS Downregulated and upregulated expression ...
In this study, we investigated the effects of ionizing radiation (IR) on human umbilical vein endothelial cells (HUVECs) in the context of senescence. HUVECs at passage number (PN)1, PN2 and PN3 were exposed to irradiation (2 Gy). The growth rate of the HUVECS was measured by proliferation assay and senescence-associated β-galactosidase assay was used to measure the number of senescent cells. T...
BACKGROUND High mortality rate of critically-ill patients could be induced by sepsis and septic shock, which is the extremely life threatening. The purpose of this work is to identify and evaluate the potential regulatory mechanism of LPS-induced inflammation associated with miR-6835 and lipid rafts in HUVECs. METHODS The 3' UTR luciferase activity of AdipoR1 was detected, which was predicted...
AIMS Recent studies suggested that human umbilical vein endothelial cells (HUVECs) transdifferentiate into cardiomyocytes and smooth muscle cells in vitro. To test the functional relevance of this observation, we examined the transdifferentiation potential of HUVECs in vivo after intracoronary cell application in Wistar rats. METHODS AND RESULTS SPECT measurements (single photon emission comp...
Dental pulp is a highly vascularized tissue requiring adequate blood supply for successful regeneration. In this study, we investigated the functional role of stem cells from human exfoliated deciduous teeth (SHEDs) as a perivascular source for in vivo formation of vessel-like structures. Primarily isolated SHEDs showed mesenchymal stem cell (MSC)-like characteristics including the expression o...
Endothelial cell dysfunction is considered to be a major cause of vascular complications in diabetes. In the present study, we investigated the protective effect of a baechu kimchi added Ecklonia cava extract (BKE) against high glucose induced oxidative damage in human umbilical vein endothelial cells (HUVECs). Treatment with a high concentration of glucose (30 mM) induced cytotoxicity, whereas...
Exposing human umbilical vein endothelial cells (HUVECs) to anoxia/reoxygenation (A/R) results in an increase in polymorphonuclear leukocyte (PMN) adhesion to HUVECs. This A/R-induced hyperadhesion is completely prevented by a previous (24 hours earlier) exposure of HUVECs to A/R. This phenomenon has been termed “A/R tolerance.” Exposing HUVECs to A/R induces an increase in nuclear factor kB (N...
Objective—The objective of the present study was to identify and characterize the cell-surface receptors on human umbilical vein endothelial cells (HUVECs) that transduce calcium transients elicited by cysteinyl leukotrienes (CysLTs), potent spasmogenic and proinflammatory agents with profound effects on the cardiovascular system. Methods and Results—Using quantitative reverse transcription–pol...
melissa officinalis l. is a medicinal plant with a large variety of pharmacological effects and traditional applications. this study aimed to evaluate the protective and antioxidant activities of the extract of m. officinalis aerial parts on human umbilical vein endothelial cells (huvecs) under oxidative stress induced by h 2 o 2 . cells were incubated with h 2 o 2 (0.5 mm, 2 h) after pretreatm...
BACKGROUND Advanced glycation end products (AGEs), senescent macroprotein derivatives formed during a normal aging process and acceleratedly under diabetic conditions, play a role in atherosclerotic cardiovascular disease. AGEs cause endothelial cell (EC) damage, an initial trigger for atherosclerosis through the interaction with a receptor for AGEs (RAGE). We have previously shown that n-butan...
