  • Patent number: 9050301
    Abstract: Provided is a pharmaceutical composition for treating corneal endothelium wounds, the composition including angiogenin as an effective ingredient. The present invention relates to a new topical therapeutic use of angiogenin for treatment of corneal endothelium wounds, wherein the angiogenin that is generally known to be involved in angiogenesis activates a PI3K/Akt/eNOS pathway thereof in ocular corneal endothelium to increase migration and proliferation of corneal endothelial cells that are not capable of self-proliferation and to promote prevention and treatment of corneal endothelial cell wounds.
    Type: Grant

  • Patent number: 7604982
    Abstract: The present invention relates to the screening method of antagonistic material of integrin using the protein chip and useful peptides screened thereby. The protein chip used in the present invention is unique substrate coated with new material, calixarene derivative, which can keep uniform and high activities of proteins. Integrin receptor protein is arrayed high densely on the chip, and materials (protein, peptide, small molecules and so on) specifically inhibiting the binding of ligand can be screened therewith. The integrins used in the present invention are integrin av f3 3 and integrin a1, b j3 3, and new antagonistic peptides screened from peptide library have high binding affinity.

  • Patent number: 6770457
    Abstract: The present invention relates to process of purifying the angiogensis inhibitor proteins expressed in E. coli and to the use of recombinant kringle 1-3 (; greenstatin) purified by the above process as a angiogenesis inhibitor and an anticancer agent. Particularly, according to the process of purifying the protein, the angiogenesis inhibitor proteins overexpressed are solubilized, refolded, and purified as a pure and active form. The greenstatin purified by the process specifically suppresses endothelial cell proliferation, anaiogenesis, and the growth of lung cancer, skin cancer, and brain tumor. Therefore, the process of this invention is applicable to the mass-production of angiogenesis inhibitor proteins such as greenstatin which is useful for the treatment of glaucoma, retinopathy, and cancers.
