They inhibit the enzyme lipoprotein lipase, which plays a key role in the intravascular lipolysis of triglycerides present in some lipoprotein classes. This review focuses on the role of ANGPTL3 as emerged from the study of genetic variants of Angptl3 gene in mice and humans. Both loss of function genetic variants and inactivation of Angptl3 gene in mice are associated with a marked reduction of plasma levels of triglyceride and cholesterol and an increased activity of lipoprotein lipase and endothelial lipase. In humans with ANGPTL3 deficiency, caused by homozygous loss of function(LOF) variants of Angptl3 gene, the levels of all plasma lipoproteins are greatly reduced. This plasma lipid disorder referred to as familial combined hypolipidemia(FHBL2) does not appear to be associated with distinct pathological manifestations. Heterozygous carriers of LOF variants have reduced plasma levels of total cholesterol and triglycerides and are at lower risk of developing atherosclerotic cardiovascular disease, as compared to non-carriers. These observations have paved the way to the development of strategies to reduce the plasma level of atherogenic lipoproteins in man by the inactivation of ANGPTL3, using either a specific monoclonal antibody or anti-sense oligonucleotides.展开更多

Recent investigations have found that angiopoietin-like protein 3 （ANGPTL3） can contribute to disorder of carbohydrate and lipid metabolism. The present study was conducted to investigate the change of ANGPTL3 expression during pregnancy toxemia, We firstly cloned the full-length cDNA of ANGPTL3 in Liuyang Black goats, revealing that goat ANGPTL3 had the typical structure of the angiopoietin-like family, and its mRNA was exclusively expressed in liver. Pregnancy toxemia of pregnant goat does with twins during late gestation was induced by being fasted for 72 h, and then they were recovered after 5 d ofrefeeding. Hepatic ANGPTL3 gene expression was significantly down-regulated concomitantly with decreased serum glucose concentration, elevated serum β-hydroxybutyrate and free fatty acid levels in pregnant toxemic goats, and these changes were reversed after refeeding. These results suggest ANGPTL3 may play a certain role in the development of pregnancy toxemia in goats.展开更多

文摘目的：探讨代谢综合征患者血清脂联素和血管生成素样蛋白3（angiopoietin-like protein3,Angptl3）水平的变化及其意义。方法：对111例代谢综合征患者和152例健康对照,采用单克隆抗体双夹心酶联免疫法测定血清Angptl3及脂联素水平,分析血清脂联素、Angptl3与脂代谢和胰岛素抵抗的关系。结果：代谢综合征组血清脂联素水平为4.22（1.01-23.29）μg/mL,低于对照组5.41（0.97-22.27）μg/mL（P〈0.05）,Angptl3在2组间差异无统计学意义。Angptl3与脂联素正相关（P〈0.001）;脂联素与高密度脂蛋白胆固醇（HDL-C）正相关（P〈0.001）,与体质量指数（BMI）、腰围（WC）、腰臀比（WHR）、甘油三酯（TG）、空腹血糖（FPG）、空腹胰岛素（FINS）、稳态模型评估的胰岛素抵抗指数（home-ostatic model assessment method-insulin resistance,HOMA-IR）均呈负相关（P〈0.001）。多元回归分析显示,脂联素是Angptl3的独立决定因素（b′=0.256,P〈0.001）。脂联素与TG,HOMA-IR呈负相关（分别b′=-0.234,b′=-0.145,P〈0.001）。结论：代谢综合征患者血清脂联素水平降低,可能与Angptl3水平降低有关。
