Defining the atherogenicity of large and small lipoproteins containing apolipoprotein B100.
Apo-E-deficient apo-B100-only mice (APOE:(-/-)APOB:(100/100)) and LDL receptor-deficient apo-B100-only mice (LDLR:(-/-)APOB:(100/100)) have similar total plasma cholesterol levels, but nearly all of the plasma cholesterol in the former animals is packaged in VLDL particles, whereas, in the latter, plasma cholesterol is found in smaller LDL particles. We compared the apo-B100-containing lipoprot...
متن کاملApo B100-containing lipoproteins are secreted by the heart.
The apo B gene is expressed in the human heart and in the hearts of human apo B transgenic mice generated with large genomic clones spanning the human apo B gene. [35S]Methionine metabolic labeling experiments demonstrated that apo B100-containing lipoproteins are secreted by human heart tissue and by human apo B transgenic and nontransgenic mouse heart tissue. Density gradient analysis reveale...
متن کاملRole of Apolipoprotein E-containing Lipoproteins
Received for publication 16 November 1981 and in revised form 18 August 1982. human fibroblasts. The binding activity of plasma from patients (per milligram of protein) was about half that of plasma from normal volunteers. All binding activity in the patients' plasma was found to reside in the HDL fraction. The binding activity of the patients' HDL (on a total protein basis) was intermediate be...
متن کاملCarboxyl-terminal truncation impairs lipid recruitment by apolipoprotein B100 but does not affect secretion of the truncated apolipoprotein B-containing lipoproteins.
Human apolipoprotein (apo) B plays an obligatory role in the assembly and secretion of hepatic triglyceride-rich lipoproteins. Investigation of the truncated human apoB variants associated with hypobetalipoproteinemia has suggested that both size and secretion of apoB-containing lipoproteins may be reduced by carboxyl-terminal truncation. To examine the role of the carboxyl terminus of apoB in ...
متن کاملIntimal retention of cholesterol derived from apolipoprotein B100- and apolipoprotein B48-containing lipoproteins in carotid arteries of Watanabe heritable hyperlipidemic rabbits.
OBJECTIVE The arterial retention of apolipoprotein (apo) B100- and apoB48-containing lipoproteins was simultaneously determined in a rabbit model of human hypercholesterolemia using 3D confocal microscopy. METHODS AND RESULTS Lipoproteins containing apoB100 (LDL) and apoB48 (chylomicron remnants) were differentially conjugated with fluorophores and simultaneously perfused at equivalent concen...
