The anti-angiogenic peptide anginex greatly enhances Galectin-1 binding affinity for glycoproteins
Angiogenesis is a key event in cancer progression and therefore a promising target in cancer treatment. Galectin-1, a β-galactoside binding lectin, is up-regulated in the endothelium of tumors of different origin and has been shown to be the target for anginex, a powerful anti-angiogenic peptide with anti-tumor activity. Here we show that when bound to anginex, galectin-1 binds various glycoprotei
