OBJECTIVE Whereas the anti-inflammatory effects of high-density lipoprotein (HDL) on endothelial cells are well described, such effects on monocytes are less studied. METHODS AND RESULTS Human monocytes were isolated from whole blood followed by assessment of CD11b activation/expression and cell adhesion under shear-flow. HDL caused a dose-dependent(More)
Humans and mice infected with different Plasmodium strains are known to produce microvesicles derived from the infected red blood cells (RBCs), denoted RMVs. Studies in mice have shown that RMVs are elevated during infection and have proinflammatory activity. Here we present a detailed characterization of RMV composition and function in the human malaria(More)
We aimed to distinguish between the effects of mutations in apoA-I on the requirements for the secondary structure and a specific amino acid sequence for lecithin:cholesterol acyltransferase (LCAT) activation. Several mutants were constructed targeting region 140-150: (i) two mutations affecting alpha-helical structure, deletion of amino acids 140-150 and(More)
Adhesion-independent growth is a neoplastic phenotype that is inducible in Rat 1a fibroblasts by enforced MYC expression. The c-Myc protein has been well characterized as a transcription factor, yet the molecular basis of c-Myc-induced neoplastic transformation has remained elusive. In this report, we demonstrate a link between ectopic MYC expression,(More)
The c-Myc protein is a transcription factor with an N-terminal transcriptional regulatory domain and C-terminal oligomerization and DNA-binding motifs. Previous studies have demonstrated that p107, a protein related to the retinoblastoma protein, binds to the c-Myc transcriptional activation domain and suppresses its activity. We sought to characterize the(More)
This paper surveys public domain supervised machine learning algorithms and performs accuracy (error rate) analysis of their classiication performance on unseen instances for twenty-nine of the University California Irvine machine learning datasets. The learning algorithms represent three types of classiier: decision trees, neural networks and rule-based(More)
AIMS/HYPOTHESIS AGE contribute to the pathogenesis of diabetic complications, including dyslipidaemia and atherosclerosis. However, the precise mechanisms remain to be established. In the present study, we examined whether AGE modification of apolipoprotein A-I (apoA-I) affects its functionality, thus altering its cardioprotective profile. MATERIALS AND(More)
OBJECTIVES Our aim was to investigate the effects of reconstituted high-density lipoprotein (rHDL) infusions on plasma high-density lipoprotein (HDL) anti-inflammatory properties and ex vivo cholesterol efflux in patients with type 2 diabetes. BACKGROUND The anti-inflammatory effects of HDL contribute to protection from cardiovascular events. Individuals(More)
The involvement of c-Myc in cellular proliferation or apoptosis has been linked to differential cyclin gene expression. We observed that in both proliferating cells and cells undergoing apoptosis, cyclin A (but not B, C, D1, and E) mRNA level was elevated in unsynchronized Myc-overexpressing cells when compared with parental Rat1a fibroblasts. We further(More)
BACKGROUND Low plasma concentration of high-density lipoprotein (HDL) cholesterol is a risk factor for cardiovascular disease and a feature of the metabolic syndrome. Rosuvastatin has been shown to increase HDL cholesterol concentration, but the mechanisms remain unclear. METHODS AND RESULTS Twelve men with the metabolic syndrome were studied in a(More)
