THERAPEUTIC AND DIAGNOSTIC TARGET GENE IN ACUTE MYELOID LEUKEMIA
Methods are provided for treating a cancer in a subject comprising administering to the subject an agent which inhibits expression of an HLX gene in the subject, or an agent which inhibits activity of an expression product of the HLX gene, and also for diagnosing a subject as likely to develop a cancer comprising determining whether a stem cell obtained from the subject expresses a HLX gene at a level in excess of predetermined control level. Kits therefor are also provided.
1 . A method of treating a preleukemia or a hematological cancer in a subject comprising administering to the subject an agent which inhibits expression of a PAK1 gene or an agent which inhibits activity of an expression product of a PAK1 gene, so as to thereby treat the preleukemia or hematological cancer.
2 . The method of claim 1 , wherein the agent inhibits expression of a PAK1 gene.
3 . The method of claim 1 , wherein the agent a small organic molecule of less than 2000 daltons, or an antibody directed against PAK1 or a fragment of said antibody.
4 . The method of claim 2 , wherein the agent is a nucleic acid molecule that effects RNAi and is directed to the PAK1 gene.
5 . The method of claim 2 , wherein the agent is an siRNA or an shRNA directed to the PAK1 gene.
6 . The method of claim 1 , wherein the method is for treating the preleukemia.
7 . The method of claim 6 , wherein the preleukemia is myelodysplastic syndrome.
8 . The method of claim 1 , wherein the hematological cancer is a leukemia.
9 . The method of claim 8 , wherein the leukemia is Acute Myeloid Leukemia.
