Compositions and methods for treating cancer

1. A method of treating cancer in a human subject, comprising:

administering an agent that blocks the expression or activity of human THOR to a human subject diagnosed with cancer under conditions such that a sign or symptom of said cancer is reduced.

2. The method of claim 1 , wherein said agent is a nucleic acid that inhibits expression of THOR.

3. The method of claim 1 , wherein said nucleic acid is selected from the group consisting of an siRNA, miRNA, an antisense nucleic acid, and an shRNA.

4. The method of claim 1 , wherein said cancer is lung cancer or melanoma.

5. The method of claim 1 , wherein said cancer expresses THOR.

6. The method of claim 5 , wherein THOR is overexpressed in said cancer relative to the level of expression in non-cancerous cells.

7. The method of claim 1 , wherein said method further comprises the step of assaying a sample of said cancer for the level of expression of THOR.

8. A method, comprising:

a) assaying a sample from a human subject diagnosed with cancer, wherein said sample comprises cancer tissue or cells for the level of expression of human THOR; and

b) administering an agent that blocks the expression or activity of said human THOR when expression of said human THOR is present in said sample.

9. The method of claim 8 , wherein said agent is a nucleic acid that inhibits expression of THOR.

10. The method of claim 8 , wherein said nucleic acid is selected from the group consisting of an siRNA, miRNA, an antisense nucleic acid, and an shRNA.

11. The method of claim 8 , wherein said cancer is lung cancer or melanoma.
