Title:	Methods and compositions for the treatment of proliferative disorders
Abstract:	The invention features methods of treating a proliferative disorder characterized by elevated Pin1 marker levels and/or reduced Pin1 Ser71 phosphorylation in a subject by administering a retinoic acid compound. Additionally, the invention features methods of treating proliferative disorders (e.g., proliferative disorders characterized by elevated Pin1 marker levels) by administering a retinoic acid compound in combination with another anti-proliferative compound. Finally, the invention also features methods including high-throughput screens for discovering and validating Pin1 inhibitors.

Patent Claims:	1. A method of treating a cancer in a subject with the cancer, said method comprising: (a) performing an assay to identify the subject as having an elevated level of Pin1 in the cells of the cancer relative to non-cancerous cells of the same tissue type; and (b) administering a retinoic acid compound to said subject, wherein the retinoic acid compound is administered to the subject as the sole Pin1 inhibitor and in an amount that reduces Pin1 activity in the cells of the cancer by 30% or more relative to a subject not administered the retinoic acid compound. 2. The method of claim 1, further comprising the administration of a second anti-proliferative compound. 3. The method of claim 1, further comprising determining Pin1 activity levels in a sample after said administration of said retinoic acid compound. 4. The method of claim 1, wherein said retinoic acid compound is selected from the group consisting of 13-cis-retinoic acid and all-trans-retinoic acid. 5. The method of claim 1, wherein said retinoic acid compound is selected from any one of the compounds in FIGS. 2A, 2B, 10A, 10D, and Table 1. 6. The method of claim 1, wherein said retinoic acid compound is deuterated. 7. The method of claim 3, wherein said sample is selected from the group consisting of a tumor sample, blood, urine, a biopsy, lymph, saliva, phlegm, and pus. 8. The method of claim 1, wherein said elevated Pin1 activity level is due to an inherited trait or a somatic mutation. 9. The method of claim 2, wherein said second anti-proliferative compound is selected from the group consisting of microtubule inhibitors, topoisomerase inhibitors, platins, alkylating agents, and anti-metabolites. 10. The method of claim 2, wherein said second anti-proliferative compound is selected from the group consisting of paclitaxel, gemcitabine, doxorubicin, vinblastine, etoposide, 5-fluorouracil, carboplatin, altretamine, aminoglutethimide, amsacrine, anastrozole, azacitidine, bleomycin, busulfan, carmustine, chlorambucil, 2-chlorodeoxyadenosine, cisplatin, colchicine, cyclophosphamide, cytarabine, cytoxan, dacarbazine, dactinomycin, daunorubicin, docetaxel, estramustine phosphate, floxuridine, fludarabine, gentuzumab, hexamethylmelamine, hydroxyurea, ifosfamide, imatinib, interferon, irinotecan, lomustine, mechlorethamine, melphalen, 6-mercaptopurine, methotrexate, mitomycin, mitotane, mitoxantrone, pentostatin, procarbazine, rituximab, streptozocin, tamoxifen, temozolomide, teniposide, 6-thioguanine, topotecan, trastuzumab, vincristine, vindesine, and vinorelbine. 11. The method of claim 2, wherein said anti-proliferative compound is administered at a low dosage or said anti-proliferative compound and said retinoic acid compound are administered at different times. 12. The method of claim 2, wherein said anti-proliferative compound is formulated as a liposomal formulation or a controlled release formulation. 13. The method of claim 2, wherein said retinoic acid compound and said anti-proliferative compound are formulated together. 14. The method of claim 1, wherein said cancer is selected from the group consisting of a leukemia[s], polycythemia vera, a lymphoma[s], Waldenstrom's macroglobulinemia, a heavy chain disease, and a solid tumor[s]. 15. The method of claim 14, wherein said cancer is selected from the group consisting of acute leukemia, acute lymphocytic leukemia, acute myelocytic leukemia, acute myeloblastic leukemia, acute promyelocytic leukemia, acute myelomonocytic leukemia, acute monocytic leukemia, acute erythroleukemia, chronic leukemia, chronic myelocytic leukemia, chronic lymphocytic leukemia, Hodgkin's disease, non-Hodgkin's disease, fibrosarcoma, myxosarcoma, liposarcoma, chondrosarcoma, osteogenic sarcoma, chordoma, angiosarcoma, endotheliosarcoma, lymphangiosarcoma, lymphangioendotheliosarcoma, synovioma, mesothelioma, Ewing's tumor, leiomyosarcoma, rhabdomyosarcoma, colon carcinoma, pancreatic cancer, breast cancer, ovarian cancer, prostate cancer, squamous cell carcinoma, basal cell carcinoma, adenocarcinoma, sweat gland carcinoma, sebaceous gland carcinoma, papillary carcinoma, papillary adenocarcinomas, cystadenocarcinoma, medullary carcinoma, bronchogenic carcinoma, renal cell carcinoma, hepatoma, bile duct carcinoma, choriocarcinoma, seminoma, embryonal carcinoma, Wilm's tumor, cervical cancer, uterine cancer, testicular cancer, lung carcinoma, small cell lung carcinoma, bladder carcinoma, epithelial carcinoma, glioma, astrocytoma, medulloblastoma, craniopharyngioma, ependymoma, pinealoma, hemangioblastoma, acoustic neuroma, oligodenroglioma, schwannoma, meningioma, melanoma, neuroblastoma, and retinoblastoma. 16. The method of claim 1, wherein said retinoic acid compound is administered in an amount sufficient to reduce the Pin1 activity in the cells of said cancer by 50% or more relative to a subject not administered said retinoic acid compound. 17. The method of claim 16, wherein said retinoic acid compound is administered in an amount sufficient to reduce the Pin1 activity in the cells of said cancer by 90% or more relative to a subject not administered said retinoic acid compound.
