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(More)
Ginkgolide B is a herbal constituent extracted from leaves of the ginkgo biloba tree. Previous studies have shown that ginkgolide B is a specific platelet activating factor (PAF) receptor antagonist, and it suppresses PAF-mediated platelet activation via competitive binding. In this study, the effect of ginkgolide B on nicotinamide adenine dinucleotide(More)
Apelin, a novel adipokine, is the specific endogenous ligand of G protein-coupled receptor APJ. Consistent with its putative role as an adipokine, apelin has been linked to states of insulin resistance. However, the function of apelin in hepatic insulin resistance, a vital part of insulin resistance, and its underlying mechanisms still remains unclear. Here(More)
To know whether thioredoxin 1 (Trx1) works for an antioxidant defense mechanism in atherosclerosis, the effect of Trx1 on the release of monocyte chemoattractant protein-1 (MCP-1), a potent chemoattractant for recruitment and accumulation of monocytes/macrophages in the intima of artery vessel, was investigated in human endothelial-like EA.hy 926 cells. It(More)
INTRODUCTION Atherosclerosis is a chronic vascular inflammatory disease. Platelets play a critic role in the initiation of vascular inflammation in atherosclerosis. In the present study, we investigated the effects of ginkgolide B on the inhibition of platelet release and the potential mechanisms. METHODS Experiments were performed in freshly human(More)
Atherosclerosis is a chronic inflammation disease that is initiated by endothelial cell injury. Oxidized low-density lipoprotein (ox-LDL) is directly associated with chronic vascular inflammation. To understand whether thioredoxin1 (Trx1) participates in an antiinflammatory defense mechanism in atherosclerosis, we investigated the effect of Trx1 on the(More)
Atherosclerosis is a complex inflammatory arterial disease. Oxidized low-density lipoprotein (ox-LDL) is directly associated with chronic vascular inflammation. In the current study, we tested the hypothesis that ginkgolide B, a component of traditional Chinese herbal medicine for heart disorder, may affect ox-LDL-induced inflammatory responses in human(More)
AIMS To investigate whether ginkgolide B (a platelet-activating factor inhibitor) affects vascular inflammation in atherosclerosis-prone apolipoprotein E-deficient (ApoE(-/-)) mice. METHODS AND RESULTS Human platelets were used to evaluate the effects of ginkgolide B on platelet aggregation and signal transduction. Ginkgolide B attenuated platelet(More)
BACKGROUND Atherosclerosis is a chronic inflammation disease which is initiated by endothelial cell injury Oxidized low-density lipoprotein (ox-LDL) is directly associated with chronic vascular inflammation. Many transcription factors take part in the initiation and progression of atherosclerosis. As a transcription factor mainly expressed in cardiovascular(More)
Reverse transcription quantitative-polymerase chain reaction (RT-qPCR) is a routine method for gene expression analysis, and reliable results depend on proper normalization by stable reference genes. Caloric restriction (CR) is a robust lifestyle intervention to slow aging and delay onset of age-associated diseases via inducing global changes in gene(More)
