    Abstract: A tumor tissue-penetrating peptide specifically binding to neuropilin, or a fusion protein, a small molecule drug, a nanoparticle, or a liposome having the peptide fused therein is provided, as well as a method for preparing the same and a pharmaceutical composition comprising the same for treating, diagnosing, or preventing cancer or angiogenesis-related diseases. The tumor tissue-penetrating peptide is fused to the C-terminus of an anticancer antibody heavy-chain constant region (Fc) and the fused antibody specifically binds to neuropilin, and specifically accumulates in tumor tissue, widens intercellular gaps between tumor vascular endothelial cells, promotes extravasation, increases infiltration within tumor tissue, and shows a remarkably increased in vivo tumor-suppressing activity. Furthermore, the tumor tissue-penetrating peptide is fused into a fusion protein and inhibits the angiogenic function of neuropilin coreceptors resulting from targeting of neuropilin, and is expected to have an alleviating effect on angiogenesis-related diseases.
