BACKGROUND There is an unmet need for proangiogenic therapeutic molecules for the treatment of tissue ischemia in cardiovascular diseases. However, major inducers of angiogenesis such as vascular endothelial growth factor (VEGF/VEGF-A) have side effects that limit their therapeutic utility in vivo, especially at high concentrations. Angiopoietin-1 has been considered to be a blood vessel stabil...
Continuous efforts have been made to find an effective treatment to improve oncologic outcomes for patients with colorectal cancer. These efforts have accomplished a noticeable achievement by using biomarker-based approaches. Antiangiogenic drugs that target the vascular endothelial growth factor (VEGF) signaling pathway have successfully expanded clinical treatment options for many cancer type...
Recruitment of various stem and progenitor cells is crucial for the regeneration of an injured organ. Levels of uric acid, one of the prototypical "alarm signals," surge after ischemia-reperfusion injury. Exogenous uric acid rapidly mobilizes endothelial progenitor cells and hematopoietic stem cells and protects the kidney from ischemia. The relatively fast responses to uric acid suggest that p...
Endothelial cell leakiness is regulated by mediators such as thrombin, which promotes endothelial permeability, and anti-inflammatory agents, such as angiopoietin-1. Here we define a new pathway involved in thrombin-induced permeability that involves the atypical protein kinase C isoform, PKCzeta. Chemical inhibitor studies implicated the involvement of an atypical PKC isoform in thrombin-induc...
To define a role for the angiopoietin/Tie2 system in astrocytoma angiogenesis, we examined the expression of angiopoietin-1 (Ang1) and angiopoietin-2 (Ang2) in these tumors by immunohistochemistry and in situ hybridization. Furthermore, we studied in vitro the effects elicited by glioblastoma cell-secreted Ang1 or by recombinant Ang1 on functions of endothelial cells (ECs). Our observations of ...
