Lack of Angiopoietin-Like-2 Expression Limits the Metabolic Stress Induced by a High-Fat Diet and Maintains Endothelial Function in Mice

Angiopoietin-like-2 (angptl2) is produced by several cell types including endothelial cells, adipocytes and macrophages, and contributes to the inflammatory process in cardiovascular diseases. We hypothesized that angptl2 impairs endothelial function, and that lowering angptl2 levels protects the endothelium against high-fat diet (HFD)-induced fat accumulation and hypercholesterolemia. Acute recombinant angptl2 reduced (P<0.05) acetylcholine-mediated vasodilation of isolated […]

Cloning, expression and purification of functionally active human angiopoietin-like protein

Angiopoietin-like protein 2 (Angptl2) is a secreted glycoprotein that has been implicated in angiogenesis, inflammation and atherosclerosis as well as enhancing the survival of human hematopoietic stem cells. Glycosylation of Angptl2 is required for biological activity and studies of angiopoietin-like protein 2 have been hindered by the lack of a source for the mature form […]
