Gene ID: , updated on Mar Summary The protein encoded by this gene is an antagonist of angiopoietin 1 Ang-1 , and both Ang-1 and Ang-2 are ligands for the endothelial tyrosine kinase receptor Tie2.
These two ligands affect angiogenesis during embryogenesis and tumorigenesis. The encoded protein disrupts the vascular remodeling ability of Ang-1 and may induce endothelial cell apoptosis. Three transcript variants encoding three different isoforms have been found for this gene. Investigated serum levels of Endothelin-1 ET-1 , angiopoietin 2 Ang-2 , and endothelial cell-specific receptor tyrosine kinase Tie-2 levels in adult Crimean-Congo hemorrhagic fever CCHF patients with significant endothelial and vascular damage.
Elevated Ang-2 highlights the role of angiogenesis in the pathophysiology of SCD and may be considered a promising marker for screening of patients at risk of sickle retinopathy and vascular dysfunction. Serum Angpt-2 showed close association with valvular calcification, atherosclerosis, inflammation and malnutrition, having significant independent prognostic value and is useful for cardiovascular event stratification in chronic peritoneal dialysis patients.

The relation between angiopoietin-2 and assessed parameters of vascular structure in type 1 diabetes reflects a state of endothelial injury and highlights the role of disturbed angiogenesis and vascular inflammation in the occurrence of diabetic complications. ANG2 did not affect apoptosis or the cell cycle. In contrast, in the in vivo system, overexpression of ANG2 increased tumor growth. When Tie2 becomes inactivated, important molecular brakes are released in the endothelium, which in turn potentiate inflammation and vascular leakage.
The ligands of Tie2, Angiopoietin-1 and Angiopoietin-2, regulate its activation status. For the very first time, a novel cytokine profile associated with cancer metastasis to the paratracheal lymph nodes were reported.

The impairment of this system underlies POAG-associated pathogenesis, supporting the possibility that Tie2 agonists could be a therapeutic option for glaucoma. Our novel noninvasive liver fibrosis model, based on serum angiopoietin-2 levels, outperforms other indices and should help substantially in managing CHC and monitoring long-term follow-up prognosis Tie1 directly interacts with Tie2 to promote ANG-induced vascular responses under noninflammatory conditions, whereas in inflammation, Tie1 cleavage contributes to loss of ANG2 agonist activity and vascular stability This systematic review and meta-analysis suggested that serum Ang-2 levels might be a potential predictor for staging, and were associated with prognosis of lung cancer.
