Lipid metabolism in chylomicron and VLDL were examined in daunomycin-induced nephrotic rats. 1) There was no difference in intestinal cholesterogenesis between the control rats and daunomycin-induced nephrotic rats. 2) The apoprotein content of chylomicron and VLDL increased in daunomycin-induced nephrotic rats. 3) Daunomycin-induced nephrotic rats showed increases in the content of apo B-48 and C-III, and a decrease in that of apo E in chylomicron. The apoprotein composition of VLDL in daunomycin-induced nephrotic rats showed increased apo B and decreased apo E. These results suggest that increased chylomicron-cholesterol is not due to increased intestinal cholesterogenesis, but to decreased chylomicron catabolism in daunomycin-induced nephrotic rats. Increased apoprotein in VLDL may contribute to the decreased catabolism by reducing LPL activity in the plasma and increased secretion from the liver of daunomycin induced nephrotic rats.

UI MeSH Term Description Entries
D008079 Lipoproteins, VLDL A class of lipoproteins of very light (0.93-1.006 g/ml) large size (30-80 nm) particles with a core composed mainly of TRIGLYCERIDES and a surface monolayer of PHOSPHOLIPIDS and CHOLESTEROL into which are imbedded the apolipoproteins B, E, and C. VLDL facilitates the transport of endogenously made triglycerides to extrahepatic tissues. As triglycerides and Apo C are removed, VLDL is converted to INTERMEDIATE-DENSITY LIPOPROTEINS, then to LOW-DENSITY LIPOPROTEINS from which cholesterol is delivered to the extrahepatic tissues.

D009404 Nephrotic Syndrome A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
