Treatment of B-cell lymphoma with microRNA
The invention relates to microRNA-34a and related microRNAs for use in the treatment of B-cell lymphoma. Likewise it relates to microRNA-34a for use in the preparation of a medicament for the treatment of B-cell lymphoma, and for a method of treatment of B-cell lymphoma comprising administering microRNA-34a. These claims are based on the observation that microRNA-34a shows strong anti-proliferative effects when overexpressed in diffuse large B-cell lymphoma (gDLBCL) cell lines, or when delivered intratumorally or systemically in xenograft models of DLBCL.
1. A method of treating a B-cell lymphoma, the method comprising administering to a patient a therapeutically effective amount of a microRNA, wherein the B cell lymphoma is diffuse large B-cell lymphoma and wherein the microRNA is a member of the miR-34 family.
2. The method of claim 1 , wherein the gastric B-cell lymphoma is high-grade gastric diffuse large B-cell lymphoma.
3. The method of claim 1 , wherein the microRNA is miR-34a, miR-34b, miR-34c-5p or miR-34c-3p.
4. The method of claim 1 , further comprising administering another active ingredient selected from cyclophosphamide, hydroxydaunorubicin, vincristine, prednisone/prednisolone, rituximab, or combinations thereof.
5. A method of treating gastric B-cell lymphoma or diffuse large B-cell lymphoma, the method comprising administering a therapeutically effective amount of a microRNA which is a member of the miR-34 family.
6. The method of claim 5 , wherein the microRNA is miR-34a.
7. A method of treating a diffuse large B-cell lymphoma, comprising administering a therapeutically effective amount of a microRNA, wherein the diffuse large B-cell lymphoma is characterized by an over-expression of FoxP1, and wherein the microRNA is a member of the miR-34 family.
8. The method of claim 7 , wherein the B-cell lymphoma is diffuse large B-cell lymphoma.
9. The method of claim 7 , wherein the B-cell lymphoma is gastric B-cell lymphoma.
10. The method of claim 7 , wherein the microRNA is miR-34a, miR-34b, miR-34c-5p or miR-34c-3p.
11. The method of claim 7 , further comprising administering another active ingredient selected from cyclophosphamide, hydroxydaunorubicin, vincristine, prednisone/prednisolone, rituximab, or combinations thereof.
12. A method of treating gastric B-cell lymphoma or diffuse large B-cell lymphoma, the method comprising administering a therapeutically effective amount of a microRNA which is a member of the miR-34 family.
13. The method of claim 12 , wherein the microRNA is miR-34a.
14. The method of claim 7 , wherein the microRNA is miR-34a and the B-cell lymphoma is diffuse large B-cell lymphoma.
15. The method of claim 12 , wherein the microRNA is miR-34a and the B-cell lymphoma is diffuse large B-cell lymphoma.
16. The method of claim 1 , wherein the microRNA is miR-34a.
17. The method of claim 7 , wherein the microRNA is miR-34a.
18. The method of claim 1 , wherein the diffuse large B-cell lymphoma is gastric diffuse large B-cell lymphoma.
19. The method of claim 5 , wherein the diffuse large B-cell lymphoma is gastric diffuse large B-cell lymphoma.
