The present invention relates to a method for diagnosing leukemia, pre-leukemia or aleukemic malignant blood diseases, a method of discriminating leukemia from pre-leukemia or aleukemic malignant blood diseases, a method of discriminating aplastic anemia from myelodysplastic syndrome, a method of diagnosing delayed engraftment of the hematopoietic stem cells after transplantation of the hematopoietic stem cells, and a method of diagnosing the graft versus host disease, each of said methods comprising quantifying stem cell growth factor (SCGF). The present invention also makes it possible to provide an agent for diagnosing leukemia, pre-leukemia or aleukemic malignant blood diseases and an agent for diagnosing delayed engraftment of the hematopoietic stem cells after transplantation of the hematopoietic stem cells or an agent for diagnosing graft versus host disease (GVHD), each containing as an active ingredient an antibody reacting with stem cell growth factor (SCGF).

Myelodysplastic syndromes display both hematological and biological heterogeneity with variable leukemia potential. To determine whether microRNAs expression offers diagnostic discrimination or influences malignant potential in MDS, bone marrow miRNA expression was investigated from prognostically distinct MDS subsets using a microarray platform. After background subtraction and normalization, data were analyzed indicating thirteen miRNA signature with statistically significant differential expression, including down-regulation of members of a leukemia associated miRNA family. A unique signature consisting of 10 miRNAs was closely associated with International Prognostic Scoring System risk category permitting discrimination between lower and higher risk disease. Selective overexpression of miRNA-181 family members was detected in higher risk MDS, indicating pathogenetic overlap with acute myeloid leukemia. Analysis of miRNA expression profile offers diagnostic utility, and provides pathogenetic and prognostic discimination in MDS.

Methods, systems and kits are provided for the clinical staging of blood disorders including myelodysplastic syndrome, myeloproliferative diseases and leukemias by differential analysis of hematologic samples for the distribution of one or more hematopoietic stem or progenitor cell subsets. Additional functional, genetic, gene expression, proteomic or other molecular analyses of the hematopoietic stem and progenitor cells from the patients can also be employed in the staging methods of the invention.

Substituted bicyclic heteroaryls having the general formulaand compositions containing them, for the treatment of general inflammation, arthritis, rheumatic diseases, osteoarthritis, inflammatory bowel disorders, inflammatory eye disorders, inflammatory or unstable bladder disorders, psoriasis, skin complaints with inflammatory components, chronic inflammatory conditions, including but not restricted to autoimmune diseases such as systemic lupus erythematosis (SLE), myestenia gravis, rheumatoid arthritis, acute disseminated encephalomyelitis, idiopathic thrombocytopenic purpura, multiples sclerosis, Sjoegren's syndrome and autoimmune hemolytic anemia, allergic conditions including all forms of hypersensitivity, The present invention also enables methods for treating cancers that are mediated, dependent on or associated with p110δ activity, including but not restricted to leukemias, such as Acute Myeloid leukaemia (AML) Myelo-dysplastic syndrome (MDS) myelo-proliferative diseases (MPD) Chronic Myeloid Leukemia (CML) T-cell Acute Lymphoblastic leukaemia (T-ALL) B-cell Acute Lymphoblastic leukaemia (B-ALL) Non Hodgkins Lymphoma (NHL) B-cell lymphoma and solid tumors, such as breast cancer.

Methods of treating MDS, or ameliorating a symptom thereof, are disclosed. Specific methods encompass the administration of one or more vitamin D compounds, or a pharmaceutically acceptable salt, solvate, hydrate, stereoisomer, clathrate, or prodrug thereof, alone or in combination with one or more additional active agents. Other methods include intermittent administration of a high dose of one or more vitamin D compounds, or a pharmaceutically acceptable salt, solvate, hydrate, stereoisomer, clathrate, or prodrug thereof, alone or in combination with one or more additional active agents. Such intermittent administration allows high doses of the vitamin D compounds to be administered while minimizing or eliminating hypercalcemia.

The present invention provides antigen binding proteins that specifically bind to Wilms' tumor protein (WT1), including humanized, chimeric and fully human antibodies against WT1, antibody fragments, chimeric antigen receptors (CARs), fusion proteins, and conjugates thereof. The antigen binding proteins and antibodies bind to HLA-A0201-restricted WT1 peptide. Such antibodies, fragments, fusion proteins and conjugates thereof are useful for the treatment of WT1 associated cancers, including for example, breast cancer, ovarian cancer, prostate cancer, chronic myelocytic leukemia, multiple myeloma, acute lymphoblastic leukemia (ALL), acute myeloid / myelogenous leukemia (AML) and myelodysplastic syndrome (MDS). In more particular embodiments, the anti-WT1 / A antibodies may comprise one or more framework region amino acid substitutions designed to improve protein stability, antibody binding and / or expression levels.

The invention encompasses 7-amido-isoindolyl compounds and methods of using these compounds and compositions in mammals for treatment, prevention or management of various diseases and disorders. Examples inlcude, but are not limited to, cancer, inflammatory bowel disease and myelodysplastic syndrome.

Methods are provided for treating hematological disorders by inhibition of DNA hypomethylation and histone deacetylase. Such disorders include, for example, acute promyelocytic leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, myelodysplastic syndromes, and sickle cell anemia. The methods comprise: administering to a patient suffering from the disease a therapeutically effective amount of a DNA methylation inhibitor such as a cysteine analog such as decitabine, in combination with an effective amount of histone deacetylase inhibitor such as hydroxamic acid, cyclic peptide, benzamide, butyrate, and depudecin.
