Compositions comprising semaphorins for the treatment of angiogenesis related diseases and methods of selection thereof
View Patent ↗A method of selecting a semaphorin for treating cancer in a subject is disclosed. The method comprises determining an expression of a semaphorin receptor on tumor cells of a tumor sample of the subject wherein an amount of the semaphorin receptor is indicative of the semaphorin suitable for treating the cancer in the subject. Methods of treating angiogenesis, kits for treating cancer and pharmaceutical compositions comprising semaphorins are also disclosed.
1. A method of treating a disease associated with pathological angiogenesis in a subject in need thereof, the method comprising administering to the subject a therapeutically effective amount of Sema3E wherein the Sema3E comprises the amino acid sequence as set forth in SEQ ID NO: 30 or a pro-protein convertase resistant Sema3E, wherein the pro-protein convertase resistant Sema3E comprises the amino acid sequence as set forth in SEQ ID NO: 37, thereby treating the disease associated with pathological angiogenesis.
2. The method of claim 1 , comprising administering a pro-protein convertase resistant SemaE comprising the amino acid sequence as set forth in SEQ ID NO: 37.
3. The method of claim 1 , comprising administering sema3E comprising the amino acid sequence set forth in SEQ ID NO: 30.
4. The method of claim 1 , wherein the disease associated with pathological angiogenesis is macular degeneration.
5. The method of claim 1 , wherein said administering comprises systemic administration.
6. The method of claim 1 , wherein said administering comprises local administration.
7. The method of claim 1 , wherein said SemaE or protein convertase resistant Sema3E is attached to a sustained-release enhancing agent.
8. The method of claim 7 , wherein said sustained-release enhancing agent is selected from the group consisting of hyaluronic acid (HA), alginic acid (AA), polyhydroxyethyl methacrylate (Poly-HEMA), polyethylene glycol (PEG), glyme and polyisopropylacrylamide.
