Anti-angiogenesis and anti-tumor effects of AdNT4-anginex

Anginex is a novel artificial peptide that can inhibit angiogenesis. AdNT4-anginex was constructed by inserting the artificial anginex gene into a recombinant adenoviral vector. We demonstrated that AdNT4-anginex inhibited migration of human endothelial cells, angiogenesis and tumor growth in in vitro and in vivo studies. Tumor growth of human H22 hepatoma in mice was inhibited after AdNT4-anginex treatment for 4 weeks, and a significant decrease in tumor size was observed as compared with the control group. Overall, these studies indicate that AdNT4-anginex is an effective anti-tumor agent, and deserves more attention and research. (C) 2009 Elsevier Ireland Ltd. All rights reserved.
