The migration of vascular smooth muscle cells (VSMCs) plays an essential role during the development of atherosclerosis and restenosis. Extensive studies have implicated the importance of extracellular matrix (ECM)-degrading proteinases in VSMC migration. A recently described family of proteinases, a disintegrin and metalloproteinase with thrombospondin(More)
OBJECTIVE Homocysteine (Hcy) is epidemiologically related to insulin resistance, which has been speculated to be a low-grade systemic inflammatory condition. Resistin acts as a critical mediator of insulin resistance associated with inflammatory conditions. We aimed to determine whether Hcy can induce insulin resistance by directly regulating the expression(More)
Hyperlipidemia is one of the major features of nephrotic syndrome (NS). Although many factors have been implicated in the pathogenesis of NS-related dyslipidemia, the underlying mechanisms remain largely uncharacterized. The present study was designed to examine the gene profile associated with lipid metabolism in the livers of nephrotic rats. NS was(More)
OBJECTIVE Vascular endothelial cells (ECs) confer atheroprotection at locations of the arterial tree where pulsatile laminar flow (PS) exists with a high shear stress and a large net forward direction. We investigated whether the PS-induced expression of the transcription factor Krüppel-Like Factor 2 (KLF2) in cultured ECs and its expression in the mouse(More)
BACKGROUND Hyperhomocysteinemia (HHcy) is an independent risk factor for liver diseases, such as fatty liver and hepatic fibrosis. However, the mechanisms underlying this pro-oxidative effect of homocysteine (Hcy) in hepatocytes remain largely unknown. Thus, we investigated the effect of Hcy on the gene expression of heme oxygenase-1 (HO-1), the primary(More)
OBJECTIVE A decreased plasma level of adiponectin is associated with obesity and metabolic syndrome and correlated with endothelial dysfunction. This study aimed to investigate the regulated expression of the newly identified adiponectin receptors (AdipoR1 and 2) and their roles in the endothelial expression of intercellular adhesion molecule-1 (ICAM-1) in(More)
Rationale: Phenotypic modulation of smooth muscle cells (SMCs), which are located in close proximity to endothelial cells (ECs), is critical in regulating vascular function. The role of flow-induced shear stress in the modulation of SMC phenotype has not been well defined. Key Words: endothelial cell Ⅲ peroxisome proliferator-activated receptor Ⅲ(More)
Niemann-Pick C1-Like 1 (NPC1L1) mediates intestinal absorption of dietary and biliary cholesterol. Ezetimibe, by inhibiting NPC1L1 function, is widely used to treat hypercholesterolemia in humans. Interestingly, ezetimibe treatment appears to attenuate hepatic steatosis in rodents and humans without a defined mechanism. Over-consumption of a high-fat diet(More)
OBJECTIVE ATP-binding cassette transporter-1 (ABCA1) mediates the active efflux of cholesterol and phospholipids, playing an important role in cholesterol homeostasis and atherogenesis. Oxidized low density lipoprotein (oxLDL) is an atherogenic molecule associated with the vascular endothelial dysfunction and development of atherosclerotic plaque. This(More)
