Human lipoprotein lipase(LPL)ELISA Kit

Key enzyme in triglyceride metabolism. Catalyzes the hydrolysis of triglycerides from circulating chylomicrons and very low density lipoproteins (VLDL), and thereby plays an important role in lipid clearance from the blood stream, lipid utilization and storage. Although it has both phospholipase and triglyceride lipase activities it is primarily a triglyceride lipase with low but detectable phospholipase activity. Mediates margination of triglyceride-rich lipoprotein particles in capillaries. Recruited to its site of action on the luminal surface of vascular endothelium by binding to GPIHBP1 and cell surface heparan sulfate proteoglycans.

2. the negatively charged IDR of GPIHBP1 traverses a vast space, facilitating capture of LPL by capillary endothelial cells and simultaneously contributing to GPIHBP1's ability to preserve LPL structure and activity. PMID: 29899144
3. nder optimal conditions, the electrochemical DNA biosensor exhibited desirable performance for the determination of rs1801177 (of the lipoprotein lipase )with a wide linearity ranging from 10 fM to 10nM and a relatively low detection limit of 3.33 fM (S/N=3). PMID: 29175215

5. Pvu II restriction fragment length polymorphism associated with an elevated risk of hypertriglyceridemia [meta-analysis] PMID: 28502159
6. When her TG levels normalized after incidental use of prednisone, an autoimmune mechanism was suspected. Immunoblot analyses showed the presence of autoantibodies to LPL in the patient's plasma. Autoantibodies to LPL decreased by 37% while patient was on prednisone, and by 68% as she subsequently transitioned to hydroxychloroquine monotherapy PMID: 28916403
7. Updated LPL structural models were generated by combining disulfide mapping, computational modeling, and data derived from single-molecule Forster resonance energy transfer. New computational suggest that LPL may dimerize using an interface that is different from the dimerization interface suggested by crystal packing contacts seen in structures of pancreatic lipase. PMID: 29303250

15. mutation of a conserved cysteine in GPIHBP1 abolishes the ability of GPIHBP1 to bind LPL PMID: 28476858

17. The expression of COBLL1, LPL, and ZAP70 corresponded to patient prognosis and to IGHV mutational status, although not absolutely. When we combined all three markers together and performed the ROC analysis, AUC increased compared to the AUC of individual gene expression. PMID: 27185377

19. The s now show: (1) that ANGPTL4 inactivates LPL by catalyzing the unfolding of its hydrolase domain; (2) that binding to GPIHBP1 renders LPL largely refractory to this inhibition; and (3) that both the LU domain and the intrinsically disordered acidic domain of GPIHBP1 are required for this protective effect. PMID: 27929370
20. Carrier status for the two common LPL variants: 447Ter (low TG/high HDL-C) and 291Ser (high TG/low HDL-C) was determined. Compared with the reference variant, the prevalence of metabolic syndrome was lower in carriers of the 447Ter variant (11.2% vs. 17.9%, P < 0.001) but with no difference in carriers of the 291Ser variant (18.4% vs. 16.5%, P = 0.59). PMID: 27676127
21. A rare variant in APOC3(rs138326449) has been associated with triglyceride, very low-density lipoprotein, and high-density lipoprotein levels, as well as risk of coronary heart disease. Effects are unlikely to be solely predictable by the action of APOC3 through LPL. PMID: 27114411
22. LPL gene polymorphisms are not genetic markers for the development of stroke in the Colombian sample used. PMID: 28293042
23. Acute hypoxia strongly inhibits lipoprotein lipase activity in differentiated human preadipocytes. PMID: 27421877
24. novel mutations cause type 1 hyperlipoproteinemia by inducing a loss or reduction in LPL secretion accompanied by a loss of LPL enzymatic activity PMID: 27578112
25. LPL HindIII polymorphism was significantly associated with the risk of coronary artery disease (CAD); for Ser447X polymorphism, it was found that only XX genotype was significantly associated with CAD risk; PvuII polymorphism had no significant association with CAD risk; LPL HindIII polymorphism might serve as a potential biomarker for CAD risk PMID: 28275220

WAT apoC-I secretion may inhibit WAT LPL activity and promote delayed chylomicron clearance in overweight and obese subjects PMID: 27040450
28. isothermal titration calorimetry (ITC) can be used for quantitative measurements of LPL activity and interactions under in vivo-like conditions, for comparisons of the properties of plasma samples from patients and control subjects as substrates for LPL, as well as for testing of drug candidates developed with the aim to affect the LPL system. PMID: 27845686
29. mAbs RE3 and RG3 bound with reduced affinity to a mutant GPIHBP1 containing an Ly6 domain mutation (W109S) that abolishes LPL binding. Immunohistochemistry studies with the GPIHBP1 mAbs revealed that human GPIHBP1 is expressed only in capillary endothelial cells. Finally, we created an ELISA that detects GPIHBP1 in human plasma. PMID: 27875259
