abstract：:Many reports have suggested that NRP-1 acts as a co-receptor for VEGF-A165 and boosts tumour growth and metastasis. This NRP-1, due to its important role in tumour progression, triggered interest in the design of new molecules able to significantly inhibit NRP-1/VEGF-A165 interaction to suppress pathological angiogene...
