Peptide having an angiogenesis inhibitory activity and a use of the peptide, related to the treatment or prevention of excessive angiogenesis-related diseases. Particularly, a novel peptide that binds, in competition with vascular endothelial growth factors (VEGF), to VEGF receptors and can significantly inhibit the proliferation, migration and differentiation of vascular endothelial cells, thereby being effectively usable as an active ingredient of a composition or a health functional food for preventing or treating diseases, such as macular degeneration, a tumor, arthritis or psoriasis, caused by excessive angiogenesis.

Mitochondria modified by a targeting protein, according to one embodiment of the present invention, can be effectively delivered to a target. In addition, when a protein of interest bound to the modified mitochondria is delivered into a cell, various activities can be exhibited. The modified mitochondria can effectively cause cancer tissue death, and thus can also be used as an anticancer agent. Furthermore, various activities are exhibited according to a protein of interest loaded on modified mitochondria, and thus the modified mitochondria can be applied in the treatment of various diseases. Additionally, a fusion protein comprising a protein of interest and a fusion protein comprising a targeting protein, according to one embodiment of the present invention, can be used in order to modify mitochondria. Moreover, mitochondria modified with the fusion proteins exhibits various effects in a target cell.

Provided herein are agents that inhibit the function (e.g., the ability to repress Tsp-1) of Protease, Serine 2 (PRSS2) by inhibiting the binding of PRSS2 to LRP1. Further provided herein are agents that bind to binding domain I of LRP1 and mimic the activity of prosaposin in stimulating Tsp-1 Methods of using these agents in treating cancer are also provided.
