OBJECTIVE GPIHBP1 is an endothelial cell protein that binds lipoprotein lipase (LPL) and chylomicrons. Because GPIHBP1 deficiency causes chylomicronemia in mice, we sought to determine whether some cases of chylomicronemia in humans could be attributable to defective GPIHBP1 proteins. METHODS AND RESULTS Patients with severe hypertriglyceridemia (n=60, with plasma triglycerides above the 95th...
BACKGROUND Signal transducer and activator of transcription 1 (Stat1) potently regulates gene expression after stimulation by certain cytokines involved in tumorigenesis and host defenses. The present study investigated a novel role for Stat1 in foam cell formation and atherosclerosis. METHODS AND RESULTS Inhibition of Stat1 activity by a Stat1-specific DNA "decoy" oligomer transfected into d...
Functional similarities between colipase and apolipoprotein C-II (apoC-II) in activating lipases suggest that apoC-II may, like colipase, preferentially interact with interfaces containing the substrates and products of lipolysis. To test this hypothesis, the binding of a peptide comprising residues of the cofactor implicated in lipid binding, apolipoprotein C-II(13-56), and, to a lesser extent...
Major Histocompatibility Complex class II (MHC-II) deficiency is a disease of gene regulation that provides a unique opportunity for the genetic dissection of the molecular mechanisms controlling transcription of MHC-II genes. Cell lines from MHC-II deficiency patients have been assigned to three complementation groups (A, B and C) believed to reflect the existence of distinct essential MHC-II ...
High density lipoproteins (HDL) from 14 patients with obstructive jaundice were examined by gradient gel electrophoresis to determine the effect of obstruction on particle size distribution. HDL from 7 of these patients were fractionated by gel permeation chromatography and further characterized by electron microscopy, SDS gel electrophoresis, apolipoprotein A-I and apolipoprotein A-II immunotu...
Ten murine monoclonal antibodies have been produced that are specific for bovine milk lipoprotein lipase. One monoclonal antibody, bLPL-mAb-7, inhibited completely the apolipoprotein C-II (apo-C-II)-dependent enzymic hydrolysis of trioleoylglycerol in a phospholipid-stabilized emulsion, but had no effect on the hydrolysis of the water-soluble substrate p-nitro-phenylacetate. Four times more bLP...
Background: Apolipoprotein A2 (APOA2) is the second major apolipoprotein of the high-density lipoprotein cholesterol (HDL-C). The study aim was to identify APOA2 gene variation in individuals within two extreme tails of HDL-C levels and its relationship with HDL-C level. Methods: This cross-sectional survey was conducted on participants from Tehran Glucose and Lipid Study (TLGS) at Research Ins...
