The present invention is directed to methods for establishing a composite marker profile for a sample derived from an individual suspected having a neoplastic condition. A composite marker profile of the invention allows for identification of prognostically and therapeutically relevant subgroups of neoplastic conditions and prediction of the clinical course of an individual. The methods of the invention provide tools useful in choosing a therapy for an individual afflicted with a neoplastic condition, including methods for assigning a risk group, methods of predicting an increased risk of relapse, methods of predicting an increased risk of developing secondary complications, methods of choosing a therapy for an individual, methods of determining the efficacy of a therapy in an individual, and methods of determining the prognosis for an individual. In particular, the method of the present invention discloses a method for establishing a composite marker profile that can serve as a prognostic indicator to predict whether the course of a neoplastic condition in a individual will be aggressive or indolent, thereby aiding the clinician in managing the patient and evaluating the modality of treatment to be used. In particular embodiments disclosed herein, the methods of the invention are directed to establishing a composite marker profile for a leukemia selected from the group consisting of Chronic Lymphocytic Leukemia (CLL), Acute Myelogenous Leukemia (AML), Chronic Myelogenous Leukemia (CML), and Acute Lymphocytic Leukemia (ALL).

The present invention relates to methods of treating cancers, e.g., leukemia. More specifically, the present invention relates to methods of treating acute and chronic leukemias including Acute Lymphocytic Leukemia (ALL), Acute Myeloid Leukemia (AML), Chronic Lymphocytic leukemia (CLL), Chronic myeloid leukemia (CML) and Hairy Cell Leukemia, by administration of pharmaceutical compositions comprising HDAC inhibitors, e.g., suberoylanilide hydroxamic acid (SAHA). The oral formulations of the pharmaceutical compositions have favorable pharmacokinetic profiles such as high bioavailability and surprisingly give rise to high blood levels of the active compounds over an extended period of time. The present invention further provides a safe, daily dosing regimen of these pharmaceutical compositions, which is easy to follow, and which results in a therapeutically effective amount of the HDAC inhibitors in vivo.

Antibodies, humanized antibodies, resurfaced antibodies, antibody fragments, derivatized antibodies, and conjugates of same with cytotoxic agents, which specifically bind to CD38, are capable of killing CD38+ cells by apoptosis, antibody-dependent cell-mediated cytotoxicity (ADCC), and / or complement-dependent cytotoxicity (CDC). Said antibodies and fragments thereof may be used in the treatment of tumors that express CD38 protein, such as multiple myeloma, chronic lymphocytic leukemia, chronic myelogenous leukemia, acute myelogenous leukemia, or acute lymphocytic leukemia, or the treatment of autoimmune and inflammatory diseases such as systemic lupus, rheumatoid arthritis, multiple sclerosis, erythematosus, and asthma. Said derivatized antibodies may be used in the diagnosis and imaging of tumors that express elevated levels of CD38. Also provided are cytotoxic conjugates comprising a cell binding agent and a cytotoxic agent, therapeutic compositions comprising the conjugate, methods for using the conjugates in the inhibition of cell growth and the treatment of disease, and a kit comprising the cytotoxic conjugate. In particular, the cell binding agent is a monoclonal antibody, and epitope-binding fragments thereof, that recognizes and binds the CD38 protein.

Methods of screening for modulators of TRIM24 (also known as TIF1-ALPHA) expression and / or biological activity are described. In particular, methods of screening of screening for modulators of TRIM24 E3 ligase activity, and specifically an E3 ligase activity directed at p53 as the target polypeptide are also described. Modulators of TRIM24 expression and activity are provided and their use in treatment of cancer, particularly in breast, colon, prostate, renal cancers and in acute lymphoblastic leukaemia. Suitable modulators of TRIM24 expression include siRNA and shRNA and can be used in the treatment of cancer and for targeting cancer stem cells.

The present invention relates to combination therapies with anti-CD38 antibodies.

The invention discloses an siRNA of humanized interleukin 6, a recombination expression carrier CAR-T and a construction method and application of the recombination expression carrier CAR-T. An IL-6 knock-down siRNA expression cassette and an siRNA expression product not only can be applied to eliminating or alleviating of CRS symptoms in treatment of B lineage acute lymphoblastic leukemia (ALL) through CAR19-T, but also can be applied to alleviating of CRS symptoms caused in treatment of all types of tumors like B lymphoma, pancreatic cancer, brain glioma and myeloma through CAR-T, and is even applied to alleviating of CRS caused by other types of treatment.

The present invention relates to combination therapies with anti-CD38 antibodies.

The present invention is directed to pharmaceutical compositions and methods of using combination therapies containing 4-(cyclopropylamino)-2-(4-(4-(ethylsulfonyl)piperazin-1-yl)phenylamino)pyrimidine-5-carboxamide, or a pharmaceutically acceptable salt thereof, and fludarabine for the treatment of cell proliferative disorders, such as undesired acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), non-Hodgkin lymphoma (NHL), including diffuse large B cell lymphoma (DLBCL); mantle cell lymphoma, acute lymphocytic leukemia (ALL), follicular lymphoma, Burkitt's lymphoma, small Lymphocytic Lymphoma (SLL) and multiple myeloma.

The invention discloses a method for promoting cell proliferation and activation of peripheral blood CD4+T lymphocyte and suppressing cell proliferation and migration of acute lymphocytic leukemia (ALL) Jurkat T cells by using red cassia tree lectin. The separation and purification of red cassia tree lectin from red cassia tree seeds can be carried out at the temperature of 1-5 DEG C during the entire process, the proliferation and activation of the peripheral blood T lymphocyte CD4 subgroup can be promoted by the red cassia tree lectin through the verifications of an MTT (3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide) experiment, a DNA (deoxyribonucleic acid) analysis and an FCM (flow cytometry), and the red cassia tree lectin is CD4+T lymphocyte mitogen more efficient than PHA (Phytohaemagglutinin) and provides a new and effective way for anti-virus infection and vaccine intensifier development; through the verifications of CCK-8 (Cell Counting Kit-8) experiment, DNA analysis, cell apoptosis analysis, ELISA (enzyme-linked immuno sorbent assay) experiments and migration assay, the red cassia tree lectin can obviously suppress the proliferation and migration of the Jurkat T lymphocyte, is a growth inhibitor more efficient for the ALL cells and provides a new and effective supplementary means for treating the hematological malignancies.

The invention belongs to the field of microbial animal cell lines, and relates to a new human acute B lymphocytic leukemia cell strain CHH-1. The in vitro isolate of the mononuclear cell of the marrow of a patient with firstly-diagnosed acute B lymphocytic leukemia undergoes cell primary culture to obtain the highly aggressive human acute B lymphocytic leukemia cell strain with add(11)(q23) chromosome abnormality, the preservation number of the cell strain is CGMCC No.11797, and the highly aggressive human acute B lymphocytic leukemia cell strain with add(11)(q23) chromosome abnormality is named as human acute B lymphocytic leukemia cell strain CHH-1, has a same clone source with patient's leukemia cells, can be infinitely and stably passed in vitro, and has the characteristics of clonality add(11)(q23) genetic abnormality, high tumorigenicity and high aggressiveness. The new human acute B lymphocytic leukemia cell strain CHH-1 provides a new good cell model for researches of human acute lymphocytic leukemia with No.11 chromosome long arm structure abnormality and development of biomedicines, and has wide prospect and great practical values in revelation of the pathogenesis of the human acute lymphocytic leukemia and development of medicines.
