PURPOSE Vascular inflammation and leakage in sepsis is mediated by Angiopoietin-1 (Ang-1) and Angiopoietin-2 (Ang-2) and their phosphorylation of the endothelial Tie-2 receptor. This study investigates levels of Ang-1 and Ang-2 in newborns to gain insight in the vascular pathophysiology of early onset sepsis (EOS) within 72 h after birth. METHODS A prospective cohort study was performed among...

Angiopoietins and angiopoietin-related proteins (ARPs) have been shown to regulate angiogenesis, a process essential for various neovascular diseases including tumors. Here, we identify ARP4/fasting-induced adipose factor/peroxisome proliferator-activated receptor gamma angiopoietin-related as a novel antiangiogenic modulatory factor. We hypothesized that ARP4 may regulate angiogenesis. In vitr...
Angiopoietin-2 is an important mediator of angiogenesis, and we hypothesized that genetic variants of ANGPT2 (the gene encoding angiopoietin-2) would result in abnormal angiogenesis and contribute to stroke susceptibility. To test our hypothesis, we investigated the association of variants in the promoter of ANGPT2 with stroke in a multi-centre case-control study. We found that the C allele of ...
Multiple classes of factors contribute to angiogenesis. In past years, the primary focus has been to understand the functions of individual classes of angiogenic factors. However, few studies have focused on the combinatorial roles of multiple classes of factors in angiogenesis. In this report, we have investigated the in vivo angiogenic processes regulated by two major classes of angiogenic fa...
Angiopoietin-2 (Ang2) appears to be a naturally occurring antagonist of the endothelial receptor tyrosine kinase Tie2, an important regulator of vascular stability. Destabilization of the endothelium by Ang2 is believed to potentiate the actions of proangiogenic growth factors. To investigate the specific role of Ang2 in the adult vasculature, we generated a nuclease-resistant RNA aptamer that ...
