Abstract:
PROBLEM TO BE SOLVED: To provide a compound useful for the treatment of angiogenic diseases of mammals, especially safe in therapeutic use, and usable as an antiangiogenic agent exhibiting selective toxicity to pathological symptoms e.g. by the selective inhibition of the proliferation of endothelial cells without or scarcely developing toxicity to normal (non-cancer) cells. SOLUTION: Mammalian kringle 5 fragments and kringle 5 fusion proteins are disclosed as compounds for treating angiogenic diseases. Methods and compounds for inhibiting angiogenic diseases are also disclosed. The kringle fragment is expressed by structure formula A-B-C-X-Y (in the formula, A is absent or a nitrogen-protective group; Y is absent or a carboxylic acid protective group; B is a natural amino acid residue; C is expressed by formula R 1 -R 2 -R 3 -R 4 (the groups are lysyl, leucyl or arginyl, tyrosyl, etc., and aspartyl, respectively); and X is absent or a natural amino acid residue or the like).

Abstract:
PROBLEM TO BE SOLVED: To provide a composition for inhibition of angiogenic diseases such as cancer, arthritis, macular degeneration, diabetic retinopathy, primary and metastatic solid tumors, cancerous tumor, sarcoma, lymphoma, psoriasis and vascular neoplasm. SOLUTION: The composition contains a kringle peptide fragment complex composed of mPEG-SLLPD-K5 or mPEG-SEED-K5, however, mPEG-SLLPD-K5 represents a peptide containing a specific 450-543 amino acid sequence combined with methoxypolyethylene glycol and serine to the N-terminal of the amino acid sequence and mPEG-SEED-K5 represents a peptide containing a specific 458-543 amino acid sequence combined with methoxypolyethylene glycol to the N-terminal of the amino acid sequence.

Abstract:
The subject invention relates to uses of a receptor referred to as GRP78 and to other endothelial cell receptors which bind to the kringle 5 region of mammalian plasminogen. More specifically, identification of the functional properties of this receptor and other such receptors allows for the development and screening of agents which, for example, mimic K5 (i.e, mimetics) and therefore inhibit angiogenesis.

Abstract:
The present invention relates to the discovery of the role of tyrosine kinase orphan receptor-1 (ROR-1) and its interactions with glucose-regulated protein 78 (GRP78) and Wnt in processes such as angiogenesis and apoptosis. The invention provides diagnostic methods based on ROR-1 and GRP78, as well as methods of modulating ROR-1, antibodies specific for ROR-1, GRP78, and Wnt, and related screening methods.
Abstract:
