The plasma concentration of human lipoprotein[a], Lp[a], is highly correlated with coronary artery disease. The protein moiety of Lp[a], apoLp[a], consists of two apoproteins, apo[a] and apoB-100, linked by one or more disulfide bonds(s). Apo[a], the protein unique to Lp[a], exists in polymorphic forms that exhibit different apparent molecular weights (Mr).(More)
We have measured intracisternal A-particle (IAP) RNA levels during development and aging in C57BL/6J mouse tissues to determine possible age-dependent changes in gene expression of these retrovirus-like sequences. Total RNA was isolated from tissues of embryonic and new born mice and mice ranging in age from 2 months to 32 months of age. RNA samples were(More)
Changes in lipoprotein distribution and in apolipoprotein E metabolism were studied in rabbits fed a diet containing 1% cholesterol. Lipoprotein distribution was monitored by rate zonal ultracentrifugation, gel filtration chromatography, and electrophoretic techniques. Normolipidemic rabbit plasma contained VLDL, IDL, LDL, and HDL. Within 1 week on the 1%(More)
A quantitiative electroimmunodiffusion (EID) assay was developed for apolipoprotein B (apoB), the major apoprotein of human plasma low density lipoproteins (LDL) and very low density lipoproteins (VLDL). Specificity, sensitivity (30-200 ng) and reproducibility (11%) were established. We used this system to determine the amount of buffer-soluble apoB in(More)
APO low density lipoprotein (apoB), the major protein in plasma low (LDL) and very low (VLDL) density lipoproteins, was localized in extracranial and intracranial arteries from normolipoproteinemics and hyperlipoproteinemics to determine if apoB extensiveness and localization varied with plasma lipoprotein profile. Specimens of carotid bifureation, internal(More)
