Title:
DIAGNOSIS AND TREATMENT OF DRUG RESISTANT LEUKEMIA
Document Type and Number:
WIPO Patent Application WO2005118865
Kind Code:
A3
Abstract:
The present invention encompasses methods and compositions useful in the diagnosis and treatment of drug resistant leukemia. The invention provides a number of genes that are differentially expressed between drug resistant and drug sensitive acute lymphoblastic leukemia (ALL). These genes act as biomarkers for drug resistant leukemia, and further serve as molecular targets for drugs useful in treating drug resistant leukemia. Accordingly, the invention provides methods of diagnosing drug resistant leukemia and methods of selecting a therapy for subjects affected by drug-resistant leukemia. The invention also provides methods for screening for compounds for treating drug-resistant leukemia, and improved methods for treating drug-resistant leukemia. Compositions of the invention include arrays, computer readable media, and kits for use in the methods of the invention.
