The status of lipoprotein lipase (LPL) has been examined in different cell types (adipose, skeletal muscle, and heart muscle cells) and different tissues (adipose, muscle, and cardiac tissues) from mouse, rat, and human. Cell and secreted activities were compared in cycloheximide-, heparin-treated cells present in culture. A gross underestimation of cell LPL activity was found; excess of LPL ov...
Lipoprotein lipase (LIPL or LPL; E.C.3.1.1.34) serves a dual function as a triglyceride lipase of circulating chylomicrons and very-low-density lipoproteins (VLDL) and facilitates receptor-mediated lipoprotein uptake into heart, muscle and adipose tissue. Comparative LPL amino acid sequences and protein structures and LPL gene locations were examined using data from several vertebrate genome pr...
The effects of insulin on lipoprotein lipase (LPL) messenger RNA (mRNA) were studied in mammary glands from virgin and late-pregnant rats. Virgin and pregnant rats (at 17 days of gestation) were subjected to a continuous infusion (35 ml/day) with 50% glucose for 72 h to produce a prolonged hyperinsulinemic-euglycemic condition. Gestation causes a 4-fold increase in LPL mRNA accompanied by a 3- ...
UNLABELLED While reviewing chronic lymphocytic leukemia (CLL) bone marrow slides, we identified cytoplasmic lipid vacuoles in CLL cells but not in normal B cells. Because lipoprotein lipase (LPL), which catalyzes hydrolysis of triglycerides into free fatty acids (FFA), is aberrantly expressed in CLL, we investigated whether LPL regulates the oxidative metabolic capacity of CLL cells. We found t...
OBJECTIVE Lipoprotein lipase (LPL) is a principal enzyme in lipoprotein metabolism, tissue lipid utilization, and energy metabolism. LPL is synthesized by parenchymal cells in adipose, heart, and muscle tissues followed by secretion to extracellular sites, where lipolyic function is exerted. The catalytic activity of LPL is attained during posttranslational maturation, which involves glycosylat...
Lipoprotein lipase (LPL) is a rate-limiting enzyme that hydrolyzes circulating triglyceride-rich lipoprotein such as very low density lipoproteins and chylomicrons. A decrease in LPL activity is associated with an increase in plasma triglycerides (TG) and decrease in high density lipoprotein (HDL) cholesterol. The increase in plasma TG and decrease in HDL cholesterol are risk factors of coronar...
زمینه و هدف: لیپوپروتین لیپاز یکی از مهمترین آنزیم های مرتبط با کنترل لیپیدهای پلاسما می باشد. تری اسیل گلیسرول، شیلومیکرون ها و VLDL به وسیله آنزیم لیپوپروتئین لیپاز (LPL) هیدرولیز می شوند. عوامل بسیاری همچون ApoCI، ApoCII، ApoCIII، ApoA5، ApoE، ANGPTL3، ANGPTL4 و ANGPTL5 در کنترل فعالیت این آنزیم دخالت دارند. بنابراین هدف مطالعه حاضر، مرور مطالعاتی بود که نقش های آنزیم لیپوپروتئین لیپاز را بر...
Background & Aims: Lipoprotein lipase (LPL) is one of the key enzymes regulating the metabolism of triglycerides (TG) and HDL cholesterol. The lipoprotein lipase (LPL) gene polymorphisms are possibly involved in the pathophysiology of dyslipidemia. Hind III polymorphism is one of the most common polymorphisms in LPL gene. In some studies, association of Hind III polymorphism with dyslipidemia h...
Engagement of TCRs induces actin rearrangements, which are critical for T cell activation. T cell responses require new actin polymerization, but the significance of higher-order actin structures, such as microfilament bundles, is unknown. To determine the role of the actin-bundling protein leukocyte-plastin (L-plastin; LPL) in this process, T cells from LPL(-/-) mice were studied. LPL(-/-) T c...
