Is hypertriglyceridemic very low density lipoprotein a precursor of normal low density lipoprotein?
The precursor-product relationship of very low density (VLDL) and low density lipoproteins (LDL) was studied. VLDL obtained from normal (NTG) and hypertriglyceridemic (HTG) subjects was fractionated by zonal ultracentrifugation and subjected to in vitro lipolysis. The individual subfractions and their isolated lipolysis products, as well as IDL and LDL, were rigorously characterized. A striking...
متن کاملAbnormal composition of hypertriglyceridemic very low density lipoprotein determines abnormal cell metabolism.
The metabolism of very low density lipoprotein (VLDL) from normolipemic (NTG) subjects, hypertriglyceridemic (HTG) subjects, and hypertriglyceridemic subjects treated with bezafibrate (BZ) was studied in cultured human skin fibroblasts. The binding, cell association, and proteolytic degradation of 125I-labeled lipoproteins and the capacity to regulate cellular sterol synthesis was determined wi...
متن کاملHypertriglyceridemic very low density lipoproteins induce triglyceride synthesis and accumulation in mouse peritoneal macrophages.
Triglyceride-rich lipoproteins may be responsible for the lipid accumulation in macrophages that can occur in hypertriglyceridemia. Chylomicrons and very low density lipoproteins (VLDL, total and with flotation constant [S(f)] 100-400) from fasting hypertriglyceridemic subjects induced a massive accumulation of oil red O-positive inclusions in unstimulated peritoneal macrophages. Cell viability...

متن کاملFenofibrate reduces low density lipoprotein catabolism in hypertriglyceridemic subjects.
This study examines the kinetic basis for the increment in plasma low density lipoprotein (LDL) levels that accompanies the fenofibrate treatment of severely hypertriglyceridemic (HTG) patients. Seven HTG men with a mean plasma triglyceride level of 1470 mg/dl were treated for 6 weeks. During treatment, their plasma triglyceride level fell by 77% and their cholesterol level by 41%. The fall in ...
