Ginkgolide B Inhibits JAM-A, Cx43, and VE-Cadherin Expression and Reduces Monocyte Transmigration in Oxidized LDL-Stimulated Human Umbilical Vein Endothelial Cells
AIM To investigate the effect of ginkgolide B on junction proteins and the reduction of monocyte migration in oxidized low-density lipoprotein- (ox-LDL-) treated endothelial cells. METHODS Human umbilical vein endothelial cells (HUVECs) were used in the present study. Immunofluorescence and Western blot were performed to determine the expression of junctional adhesion molecule-A (JAM-A), conn...
متن کاملGinkgolide B Reduces LOX-1 Expression by Inhibiting Akt Phosphorylation and Increasing Sirt1 Expression in Oxidized LDL-Stimulated Human Umbilical Vein Endothelial Cells
Oxidized low-density lipoprotein (ox-LDL) is an important risk factor in the development of atherosclerosis. LOX-1, a lectin-like receptor for ox-LDL, is present primarily on endothelial cells and upregulated by ox-LDL, tumor necrosis factor a, shear stress, and cytokines in atherosclerosis. Recent studies demonstrated that ginkgolide B, a platelet-activating factor receptor antagonist, has ant...
متن کاملHyperglycemia- Induced NF-κB Activation Increases microRNA-146a Expression in Human Umbilical Vein Endothelial Cells
Background & objectives: Nuclear Factor kappa B (NF-κB), a master switch transcription factor, plays a critical role in the progression and development of hyperglycemia-induced microangiopathy. Hyperglycemia activates NF-κB, and subsequently increases pro-inflammatory cytokines such as TNF-α, IL-6 and IL-1β leading to development of inflammation. Some new studies have revealed the involvement o...
متن کاملGreen tea polyphenols inhibit oxidized LDL-induced NF-KB activation in human umbilical vein endothelial cells.
AIM To examine the anti-inflammatory effects of green tea polyphenols on oxLDL-mediated TNFalpha expression and NF-KB activation in the human umbilical vein endothelial cells (HUVECs). METHODS We postulate that green tea polyphenols regulate TNF-alpha gene expression by modulating NF-KB activation through their inhibition effect on IKB Kinase (IKK) activity and as scavenger of free radicals. ...
متن کاملOxidized LDL induces proliferation and hypertrophy in human umbilical vein endothelial cells via regulation of p27Kip1 expression: role of RhoA.
Oxidized LDL (OxLDL) induces proliferation in human umbilical vein endothelial cells (HUVEC). The influence of OxLDL on the cyclin-dependent kinase inhibitor p27(Kip1), on the activity of the small GTPase RhoA as a known regulator of p27(Kip1), and on resulting cell proliferation and hypertrophy was studied. HUVEC were stimulated with OxLDL (1 to 50 mug/ml). Proliferation was quantified by (3)H...
