Another example of peptide-based galectin ligand for cancer treatment is Anginex (29, Table 3), a 33-mer synthetic peptide originally designed to reproduce the β-sheet structure of antiangiogenic proteins like platelet factor 4 (PF4), interleukin (IL)-8, and bactericidal/permeability-increasing protein (BPI) (155, 156). The gene discussed is PF4; the disease is cancer.
