Human angiopoietin-like protein 3,ANGPTL3 ELISA Kit

    ANGPTL3是一种新发现的蛋白质，主要与脂质代谢和心血管疾病有关。最近的研究发现，ANGPTL3的缺失可以导致高密度脂蛋白胆固醇（HDL-C）升高和低密度脂蛋白胆固醇（LDL-C）降低，从而降低心血管疾病风险。因此，ANGPTL3可能成为治疗高胆固醇血症和心血管疾病的新靶点。

Acts in part as a hepatokine that is involved in regulation of lipid and glucose metabolism. Proposed to play a role in the trafficking of energy substrates to either storage or oxidative tissues in response to food intake. Has a stimulatory effect on plasma triglycerides (TG), which is achieved by suppressing plasma TG clearance via inhibition of LPL activity. The inhibition of LPL activity appears to be an indirect mechanism involving recruitment of proprotein convertases PCSK6 and FURIN to LPL leading to cleavage and dissociation of LPL from the cell surface; the function does not require ANGPTL3 proteolytic cleavage but seems to be mediated by the N-terminal domain, and is not inhibited by GPIHBP1. Can inhibit endothelial lipase, causing increased plasma levels of high density lipoprotein (HDL) cholesterol and phospholipids. Can bind to adipocytes to activate lipolysis, releasing free fatty acids and glycerol. Suppresses LPL specifically in oxidative tissues which is required to route very low density lipoprotein (VLDL)-TG to white adipose tissue (WAT) for storage in response to food; the function may involve cooperation with circulating, liver-derived ANGPTL8 and ANGPTL4 expression in WAT. Contributes to lower plasma levels of low density lipoprotein (LDL)-cholesterol by a mechanism that is independent of the canonical pathway implicating APOE and LDLR. May stimulate hypothalamic LPL activity.; In vitro inhibits LPL activity; not effective on GPIHBP1-stabilized LPL.; Involved in angiogenesis. Binds to endothelial cells via integrin alpha-V/beta-3 (ITGAV:ITGB3), activates FAK, MAPK and Akt signaling pathways and induces cell adhesion and cell migration. Secreted from podocytes, may modulate properties of glomerular endothelial cells involving integrin alpha-V/beta-3 and Akt signaling. May increase the motility of podocytes. May induce actin filament rearrangements in podocytes implicating integrin alpha-V/beta-3 and Rac1 activation. Binds to hematopoietic stem cells (HSC) and is involved in the regulation of HSC activity probably implicating down-regulation of IKZF1/IKAROS.

8. Our findings demonstrate that complete ANGPTL3 deficiency associates with highly reduced postprandial lipemia probably due to faster catabolism of intestinally derived lipoproteins, larger expansion of the postprandial FFA pool, and decreased influx of dietary-derived fatty acids into the liver. These results add information on mechanisms underlying hypolipidemia in familial combined hypolipidemia (FHBL2). PMID: 27040449

15. An ANGPTL3-4-8 model was proposed to explain the variations of lipoprotein lipase (LPL) activity during the fed-fast cycle. Feeding induces ANGPTL8, activating the ANGPTL8-ANGPTL3 pathway, which inhibits LPL in cardiac and skeletal muscles to direct circulating triglycerides (TG) to white adipose tissue; the reverse is true during fasting, which suppresses ANGPTL8 but induces ANGPTL4, thereby directing TG to muscles.
