background : many types of cancer cells require a supply of fatty acids (fa) for growth and survival, lpl, in the presence of triglyceride-rich lipoproteins, accelerates the growth of these cells. recent evidence shows that lpl plays important roles in inflammation and obesity, implies that it is an appropriate general target for chemo preventive and chemotherapeutic agents. thus, we reported l...

background: familial chylomicronemia syndrome is a rare disorder of lipoprotein metabolism due to familial lipoprotein lipase or apolipoprotein c-ii deficiency or the presence of inhibitors to lipoprotein lipase. it manifests as eruptive xanthomas, acute pancreatitis, and lipaemic plasma due to marked elevation of triglyceride and chylomicrons levels. case presentation: we report a rare case of...

Excessive circulating triglycerides due to reduction or loss of lipoprotein lipase activity contribute to hypertriglyceridemia and increased risk for pancreatitis. The only gene therapy treatment for lipoprotein lipase deficiency decreases pancreatitis but minimally reduces hypertriglyceridemia. Synthesized in multiple tissues including striated muscle and adipose tissue, lipoprotein lipase is ...

Lipoprotein lipase synthesis in adipose tissue was greater in rats fed ad libitum or refed than in fasted rats. Insulin alone and together with dexamethasone increased lipoprotein lipase synthesis in adipose tissue incubated in vitro. The changes in relative lipoprotein lipase synthesis (immunoprecipitable 35S-labelled lipoprotein lipase as a fraction of general [35S]protein after pulse-labelli...

Addition of heparin to isolated fat cells incubated at 23” resulted in a 3-fold increase in release of lipoprotein lipase activity into the incubation medium. This increase in medium lipoprotein lipase activity was not due to enhancement or stabilization of lipase activity present in the medium. The maximum increase in lipoprotein lipase activity was obtained on addition of 0.1 unit of heparin ...

Lipoprotein lipase activity in adipose tissue responds rapidly to changes in the physiological state. To study what mechanisms are involved in the regulation, guinea pigs were fasted and the decrease in adipose-tissue lipoprotein lipase activity was compared with the decreases in mRNA and lipase synthesis. The mRNA pattern (three species) did not change. There was a close parallelism between th...

there are no adequate data that evaluate the safety and effectiveness of lowering triglyceride levels in infants. the authors report a neonate affected by familial hyperchylomicronemia, while being investigated for sepsis the serum sample obtained for blood counts was discovered to be lipaemic and the case was subsequently investigated for dyslipidemia. based on this very abnormal lipid profile...

It has been postulated that lipoprotein lipase, an enzyme important in the uptake of fatty acids into tissues, is bound to the vascular endothelial cell surface and that this binding occurs through attachment to heparinlike glycosaminoglycans. Furthermore, it is thought that heparin releases the enzyme from its attachment to the endothelium into the circulation. These hypotheses have never been...

The molecular defects resulting in a deficiency of lipoprotein lipase activity in a patient with the familial hyperchylomicronemia syndrome have been identified. Increased lipoprotein lipase mass but undetectable lipoprotein lipase activity in the patient's post-heparin plasma indicate the presence of an inactive enzyme. No major gene rearrangements were identified by Southern blot analysis of ...
