Methods and compositions to inhibit metastasis and to treat fibrosis and to enhance wound healing
View Patent ↗Methods and compositions are provided for inhibiting or treating metastasis based on discoveries regarding Kif19 and Cep192. Methods and compositions are provided for enhancing wound healing, treating fibrosis, reducing scarring and treating nerve pain.
1. A method of treating metastasis or inhibiting metastasis in a subject having osteosarcoma comprising administering to the subject an amount of an siRNA or shRNA inhibitor of KIF19 effective to treat metastasis or inhibit metastasis of osteosarcoma.
2. The method of claim 1 , wherein the KIF19 is human KIF19.
3. The method of claim 1 , wherein the siRNA directed to KIF19 is administered.
4. The method of claim 1 , wherein the shRNA directed to KIF19 is administered.
5. The method of claim 3 , wherein the siRNA is administered as a composition comprising the siRNA encapsulated completely or partially by a nanoparticle.
6. The method of claim 4 , wherein the shRNA is administered as a composition comprising the shRNA encapsulated completely or partially by a nanoparticle.
7. The method of claim 5 , wherein the nanoparticle is a liposomal nanoparticle.
8. The method of claim 6 , wherein the nanoparticle is a liposomal nanoparticle.
9. The method of claim 5 , wherein the nanoparticle is pegylated.
10. The method of claim 6 , wherein the nanoparticle is pegylated.
11. The method of claim 3 , wherein the siRNA is administered as a viral vector.
12. The method of claim 4 , wherein the shRNA is administered as a viral vector.
13. The method of claim 3 , wherein the siRNA is modified at a 2 position of a sugar of at least one nucleotide thereof of at least one strand thereof.
14. The method of claim 13 , wherein the siRNA is modified with a 2′-OMe.
15. The method of claim 3 , wherein the siRNA is administered as a composition comprising the siRNA encapsulated in a nanoparticle.
16. The method of claim 4 , wherein the shRNA is administered as a composition comprising the shRNA encapsulated in a nanoparticle.
17. The method of claim 3 wherein the siRNA is selected from SEQ ID NO:5 and SEQ ID NO:6.
18. The method of claim 4 , wherein the shRNA is modified at a 2 position of a sugar of at least nucleotide thereof of at least one strand thereof.
19. The method of claim 18 , wherein the shRNA is modified with a 2′-OMe.
