Rates of removal and degradation of chylomicron remnants by isolated perfused rat liver.
Chylomicron remnants are removed intact by isolated perfused rat livers and their lipid components are metabolized by the liver (Biochim. Biophys. Acta 488: 464, 1977). The present study provides quantitative information regarding these processes. When the lipoprotein concentration of the perfusate was constant, the removal of chylomicron remnants increases lineraly for 17 min. The rate of remn...
متن کاملLipoprotein lipase enhances removal of chylomicrons and chylomicron remnants by the perfused rat liver.
Lipoprotein lipase has been found to efficiently mediate binding of lipoproteins to cell surfaces and to the low density lipoprotein (LDL) receptor-related protein (LRP) under cell culture conditions (Beisiegel et al. 1991. Proc. Natl. Acad. Sci. USA. 88: 8242-8346). This supports the previously proposed idea that the lipase could have a role in receptor-mediated uptake of chylomicron remnants ...

متن کاملDegradation of serum amyloid A by isolated perfused rat liver.
Degradation of serum amyloid A (SAA) was studied in the isolated perfused rat liver. Radioiodinated SAA was reconstituted with high density lipoproteins (HDL) and administered to rats. Plasma was taken 1 h later, and the HDL were isolated for use as tracer. HDL-bound 125I-SAA was cleared from the plasma of intact animals at a rate similar to SAA in native human HDL. Catabolism of SAA and HDL ap...
متن کاملComparison of the metabolism of chylomicrons and chylomicron remnants by the perfused liver.
1. The hepatic metabolism of chylomicrons and chylomicron remnants was compared after adding approximately equal numbers of each lipoprotein particle to the perfusate of isolated livers. 2. At least 40% of the added remnants were metabolized by the liver compared with less than 3% for chylomicrons. 3. There was significantly more net removal of labelled remnants than of chylomicrons by the live...
