膜联蛋白A1(Annexin A1,Anxa1)是一种高度特异性的肿瘤血管表面标志物。我们使用肽展示噬菌体技术鉴定了一种碳水化合物配体模拟7聚体肽IFLLWQR(IF7),它可以靶向肿瘤血管系统中的Anxa1。在这里,我们描述了碳水化合物与Anxa1的结合活性,Anxa1与硫酸乙酰肝素的结合活性,以及IF7与抗癌药物结合在肿瘤靶向中的治疗潜力。
Annexin A1 (Anxa1) is a highly specific surface marker of tumor vasculature. We used peptide-displaying phage technology to identify a carbohydrate ligand-mimicking 7-mer peptide, IFLLWQR (IF7), which can target Anxa1 in tumor vasculature. Here, we describe the binding activity of carbohydrate to Anxa1, Anxa1 to heparan sulfates, and the therapeutic potential of IF7 conjugated with anticancer drugs in tumor targeting.
