miR-150 for the treatment of blood disorders
The invention provides methods of treating certain blood related disorders, in particular, thrombocytopenia and anemia comprising increasing miR-150 expression or inhibiting miR-150 in progenitor cells respectively.
1. A method of treating anemia in a host in need thereof, the method comprising administering an effective amount of an agent that inhibits miR-150 in a cell to a host, wherein the agent is a nucleic acid sequence that is at least 90% identical to SEQ. ID. No. 3.
2. The method of claim 1 , wherein the cell is a progenitor cell.
3. The method of claim 2 , wherein the progenitor cell is a hematopoietic progenitor cell.
4. The method of claim 1 , wherein the agent is an antagomir of miR-150, an anti-miR-150 oligonucleotide, an antisense oligonucleotide to miR-150 or a locked nucleic acid that anneals to miR-150.
5. A method of treating anemia in a host in need thereof, the method comprising:
a. obtaining a sample of hematopoietic progenitor cells from said host;
b. contacting the hematopoietic progenitor cells with a vector comprising a nucleic acid sequence that is at least 90% identical to SEQ. ID. No. 3; and
c. introducing the cell from step b into the same host.
