  • Patent number: 7750133
    Abstract: This invention discloses two new VEGI isoforms named VEGI-192a and VEGI-192b consisting of 192 amino acid residues. These isoforms show endothelial cell-specific expression and share a C-terminal 151-residues segment with the previously described VEGI-174 and VEGI-251. Methods of using these isoforms of VEGI in diagnosing, screening agonist and antagonist of the isoforms, and treating various angiogenesis-related diseases are also disclosed.
    Type: Grant
    Filed: December 6, 2007
    Date of Patent: July 6, 2010
    Assignee: Georgetown University
    Inventors: Luyuan Li, Hongguang Pan

  • Patent number: 5491220
    Abstract: Structural analogues of fibroblast growth factors have an amino acid sequence replacement in the ninth or tenth .beta.-strand of the factor, or the sequence that corresponds to the surface loop that connects the ninth and tenth .beta.-strands, such that the folding of the molecule is not significantly perturbed. Preferred analogues have the amino acid sequence replacement in the surface loop that extends from the ninth .beta.-strand to the tenth .beta.-strand and have the overall secondary and tertiary structure of the original factor, and bind to heparin and a member or members of the fibroblast growth factor receptor family with high affinity. In some embodiments, the analogues are prepared by replacing the surface loop sequence that connects the ninth and tenth .beta.-strand with another amino acid sequence such as a loop sequence from another structurally related fibroblast growth factor or an interleukin.
