Apolipoprotein CIII links hyperlipidemia with vascular endothelial cell dysfunction.
BACKGROUND Apolipoprotein CIII (apoCIII) is a component of some triglyceride-rich very-low-density and low-density lipoprotein and is elevated in dyslipidemia with insulin resistance and the metabolic syndrome. We previously reported that apoCIII directly activates proinflammatory and atherogenic signaling in vascular endothelial cells through protein kinase C-beta (PKCbeta). Because PKCbeta im...
متن کاملApolipoprotein CIII links islet insulin resistance to β-cell failure in diabetes.
Insulin resistance and β-cell failure are the major defects in type 2 diabetes mellitus. However, the molecular mechanisms linking these two defects remain unknown. Elevated levels of apolipoprotein CIII (apoCIII) are associated not only with insulin resistance but also with cardiovascular disorders and inflammation. We now demonstrate that local apoCIII production is connected to pancreatic is...
متن کاملSstI Polymorphism of the Apolipoprotein CIII Gene in Iranian Hyperlipidemic Patients: A Study in Semnan Province
Objective(s) The Sst-I polymorphic site on the 3' untranslated region of the apo CIII gene, has been previously reported to be associated with hypertriglyceridemia. The aim of the present study was to explore the association between Sst-I polymorphism with plasma lipid and lipoprotein levels in hyperlipidemic (HLP) patients from Semnan province, Iran. Materials and Methods Genomic DNA was pr...
متن کاملChylomicronemia due to apolipoprotein CIII overexpression in apolipoprotein E-null mice. Apolipoprotein CIII-induced hypertriglyceridemia is not mediated by effects on apolipoprotein E.
The mechanism of apolipoprotein (apo) CIII-induced hypertriglyceridemia remains uncertain. We crossed apoCIII transgenic and apoE gene knockout (apoE0) mice, and observed severe hypertriglyceridemia with plasma triglyceride levels of 4,521+/-6, 394 mg/dl vs. 423+/-106 mg/dl in apoE0 mice, P < 0.00001 for log(triglycerides [TG]). Cholesterols were 1,181+/-487 mg/dl vs. 658+/-151 mg/dl, P < 0.000...
متن کاملImpact of Magnesium Deficiency on Pancreatic β-Cell Function in Type 2 Diabetic Nigerians
Objective: Pancreatic b-cell dysfunction is described to be present at the diagnosis of type 2 diabetes mellitus (T2DM) and progressively deteriorated with disease duration. However, its progression is variable and potentially influenced by several factors. The Magnesium (Mg) deficiency mediates insulin resistance but reports regarding its role in pancreatic β-cell dysfunction are scarce and co...
