Saturated and unsaturated fatty acids independently regulate low density lipoprotein receptor activity and production rate.
These studies examine the regulation of plasma low density lipoprotein (LDL)-cholesterol levels by varying quantities of dietary saturated and polyunsaturated triacylglycerols. At a constant load of 0.12% cholesterol and 20% triacylglycerol, substitution of polyunsaturated for saturated triacylglycerols caused LDL receptor activity to increase from 25% to 80% of control and reduced the LDL-chol...
متن کاملDifferential effects of saturated fatty acids on low density lipoprotein metabolism in the guinea pig.
Studies have shown that dietary fat saturation affects guinea pig plasma low density lipoprotein (LDL) levels by altering both LDL receptor-mediated catabolism and flux rates of LDL (Fernandez et al. 1992. J. Lipid Res. 33: 97-109). The present studies investigated whether saturated fatty acids of varying chain lengths have differential effects on LDL metabolism. Guinea pigs were fed 15% (w/w, ...
متن کاملLow density lipoprotein receptor related protein 1 variant interacts with saturated fatty acids in Puerto Ricans
OBJECTIVE Low-density lipoprotein receptor-related protein 1 (LRP1) is a multifunctional endocytic receptor that is highly expressed in adipocytes and the hypothalamus. Animal models and in vitro studies support a role for LRP1 in adipocyte metabolism and leptin signaling, but genetic polymorphisms have not been evaluated for obesity in people. DESIGN AND METHODS We examined whether dietary f...
متن کاملEnhanced macrophage degradation of biologically modified low density lipoprotein.
Low density lipoprotein (LDL) conditioned by incubation in the presence of rabbit aortic or human umbilical vein endothelial cells (endothelial cell-modified LDL) was degraded by macrophages three to five times more rapidly than LDL incubated in the absence of cells (control LDL). This enhanced degradation occurred mostly via a high affinity, saturable pathway related to the pathway for macroph...
متن کاملEndothelial lipase releases saturated and unsaturated fatty acids of high density lipoprotein phosphatidylcholine.
We assessed the ability of endothelial lipase (EL) to hydrolyze the sn-1 and sn-2 fatty acids (FAs) from HDL phosphatidylcholine. For this purpose, reconstituted discoidal HDLs (rHDLs) that contained free cholesterol, apolipoprotein A-I, and either 1-palmitoyl-2-oleoylphosphatidylcholine, 1-palmitoyl-2-linoleoylphosphatidylcholine, or 1-palmitoyl-2-arachidonylphosphatidylcholine were incubated ...
