26. Apolipoprotein B variant derived from rat intestine.
A variant of apolipoprotein B has been observed in the lymph lipoproteins [chylomicrons, very low density lipoproteins (VLDL), and low density lipoproteins (LDL)] of rats, in the plasma VLDL of fed rats, and in the plasma VLDL and LDL of rats fed a high-fat, high-cholesterol diet. It is the sole apolipoprotein B in the chylomicrons and VLDL of lymph. It diff

28. Heterogeneity of apolipoprotein B: isolation of a new species from human chylomicrons.
Low density lipoproteins and the triglyceride-rich lipoproteins of human serum each contain proteins of high molecular weight termed apolipoprotein B, which have previously been thought to be identical. We have isolated four species of apolipoprotein B with unique molecular weights and amino acid compositions. We have assigned numerical designations to these

32. Very low density lipoproteins in intestinal lymph: origin, composition, and role in lipid transport in the fasting state
The transport of endogenous lipids in the lipoproteins of mesenteric lymph was studied in fasting rats with mesenteric lymph fistulas. The lymph was found to contain, in addition to chylomicrons (Sf >400), a significant amount of another, more dense, triglyceride-rich fraction, the very low density lipoproteins (VLDL), which showed a peak Sf of 102. The VLDL

33. Human very low density lipoproteins and chylomicrons can protect against endotoxin-induced death in mice.
Endotoxemia stimulates many physiologic responses including disturbances in lipid metabolism. We hypothesized that this lipemia may be part of a defensive mechanism by which the body combats the toxic effects of circulating endotoxin. We tested the effects of mixtures of endotoxin, lipoproteins, and lipoprotein-free plasma and determined the ability of varyi

34. Characterization of remnants produced during the metabolism of triglyceride-rich lipoproteins of blood plasma and intestinal lymph in the rat.
The metabolism of intravenously injected large and small chylomicrons from intestinal lymph and of very low density lipoproteins from blood plasma was studied in functionally eviscerated "supradiaphragmetic" rats. For studies with lymph lipoproteins, recipient animals were injected with 4-amino-pyrazolopyrimidine 18 h before injection of lipoprotein to preve

35. Evidence for the chylomicron origin of lipids accumulating in diabetic eruptive xanthomas: a correlative lipid biochemical, histochemical, and electron microscopic study
Plasma lipoprotein alterations in nine insulin-dependent diabetics with hyperlipemia have been related to the lipid accumulating in eruptive xanthomas evolving in these patients. Histochemical and electron microscopic examination of xanthomas have been correlated with the lipid analyses in order to obtain additional evidence regarding the lipoprotein origin

36. Lipoprotein lipase enhances the binding of chylomicrons to low density lipoprotein receptor-related protein.
Chylomicron catabolism is known to be initiated by the enzyme lipoprotein lipase (triacylglycero-protein acylhydrolase, EC 3.1.1.34). Chylomicron remnants, produced by lipolysis, are rapidly taken up by the liver via an apolipoprotein E (apoE)-mediated, receptor-dependent process. The low density lipoprotein (LDL) receptor-related protein (LRP) has been sugg
