Organism Comment Expression
Homo sapiens heparanase is up-regulated in essentially all human tumors examined. Oxidized lipid- or angiotensin-induced expression of heparanase in macrophages may be a primary mechanism increasing heparanase in atherosclerotic plaques up

General Information

General Information Comment Organism
physiological function heparanase, the sole mammalian endoglycosidase degrading heparan sulfate, is causally involved in cancer metastasis, angiogenesis, inflammation and kidney dysfunction. Involvement of heparanase in atherosclerosis and other vessel wall pathologies, overview. Heparanase promotes thrombosis after vascular injury and contributes to a pro-coagulant state in human carotid atherosclerosis. Heparanase emerges as a regulator of vulnerable lesion development and potential target for therapeutic intervention in atherosclerosis and related vessel wall complications. The enzyme plays a direct role of heparanase in tumor metastasis. heparanase promotes gene expression (i.e., VEGF, tissue factor, HGF, RANKL, TNFalpha) and signaling pathways (i.e., phosphorylation of Akt, Src, Erk, EGF-receptor, insulin receptor) of which some are mediated by its C-terminus domain, devoid of heparanase enzymatic activity. Heparanase activates macrophages via Toll-like receptor similar to the marked increase of TNFalpha and IL-1 following addition of heparanase to monocytes isolated from human peripheral blood. Molecular mechanism underlying cytokine induction by heparanase, overview. Heparanase alters arterial structure and repair following endovascular stenting. The enzyme is a potent regulator of vascular remodeling, both on the level of paracrine regulation of vascular homeostasis and as an effector molecule in vascular response to injury Homo sapiens
