Methods and compositions are provided for the identification of stem cells and cancer stem cells. β-catenin is also identified as a target for the development of therapeutic moieties against hematopoietic tumors, i.e. leukemia and lymphoma cells, which may include screening assays directed at β-catenin, or members of the β-catenin signaling pathway. Cellular proliferation in hematopoietic cells can be altered by introducing stabilized β-catenin into a hematopoietic cell that is altered in its ability to undergo apoptosis but which is not fully transformed. The immortalized cells are useful in screening assays, and in the analysis of pathways by which hematopoietic cells undergo transformation.

An inducing agent or enhancing agent, for the expression of HM1.24 antigen in hematopoietic tumor cells, comprising interferon α, interferon γ, or the IRF-2 protein as an active ingredient, as well as an anti-tumor agent for hematopoietic tumors which comprises a combination of said inducing agent or enhancing agent and an antibody against HM1.24.

The invention relates to a kit for detecting an expression index of mRNA (messager Ribose Nucleic Acid) of a WT1 (Wilms Tumor 1) gene, and belongs to the field of biotechnology. The kit comprises detection primers, a fluorescent probe, a cDNA (complementary Deoxyribose Nucleic Acid) first strand synthesis reagent, a fluorescent quantitative PCR (Polymerase Chain Reaction) mixed solution, negative reference and positive reference, wherein the detection primers and the fluorescent probe comprise a WT1 gene primer, an internal reference gene ABL primer and a Taqman fluorescent probe. The WT1 gene is related with hematopoietic tumor incidence, is of over-expression in about 80% of patients with newly diagnosed acute myelocytic leukemia and acute lymphocytic leukemia, is recognized as a leukemia marker gene, and can serve as an independent minimal residue disease monitoring and prognosis prompting index. The level of the mRNA of the WT1 gene is detected by adopting a fluorescent quantitative PCR technology with higher sensitivity and specificity, and both the specificity and the sensitivity of a detection result are remarkably improved. The kit provides a brand-new quick, simple and convenient gene diagnosis technology for prognosing the acute myelocytic leukemia and the acute lymphocytic leukemia and confirming chemotherapy regimens.

Disclosed are methods for detecting adriamycin resistance in a test neoplastic cell from a non-hematological cancer. The methods include detecting a level of p16 expression in the test neoplastic cell of a given origin or cell type, and comparing the level of p16 expression detected in the test neoplastic cell to the level of p16 expression in a nonresistant neoplastic cell of the same origin or cell type, wherein the test neoplastic cell is adriamycin resistant if the level of p16 expression is greater than the level of p16 expression in the nonresistant neoplastic cell of the same origin or cell type. Also disclosed are therapeutic compositions comprising an agent that inhibits p16 and a pharmaceutically acceptable carrier.

An inducing agent or enhancing agent, for the expression of HM1.24 antigen in hematopoietic tumor cells, comprising interferon α, interferon γ, or the IRF-2 protein as an active ingredient, as well as an anti-tumor agent for hematopoietic tumors which comprises a combination of said inducing agent or enhancing agent and an antibody against HM1.24.

A therapeutic and / or prophylactic agent for a hematopoietic tumor, which comprises a thiadiazoline derivative represented by the general formula (I), or a pharmaceutically acceptable salt thereof:[Formula 1][wherein, n represents an integer of 1 to 3, R1 represents a hydrogen atom, R2 represents lower alkyl, or R1 and R2 are combined together to represent alkylene, R3 represents lower alkyl, R4 represents NHSO2R6 (wherein R6 represents hydroxy or the like) or the like, and R5 represents aryl or the like] and the like are provided.

The diagnostic markers that provide novel diagnostic criteria to blastic plasmacytoid dendritic cell neoplasm (BPDCN) has been searched, and the presence of immunoblastoid cytomorphology, 8q24 rearrangement, and MYC expression were established as novel markers for subtyping BPDCN. It has been further found that the inhibitors which directly or indirectly inhibit the expression, functions, or signaling pathways of MYC, such as BET bromodomain-selective inhibitors or aurora kinase inhibitors, are effective in MYC-positive BPDCN, and HDAC inhibitors or BCL2 family protein inhibitors are effective as therapeutic drugs for BPDCN.

The present invention relates to a method for the diagnosis of low overall survival acute promyelocytic leukemia and / or of predicting and / or monitoring the response and / or the efficacy of a therapy for acute promyelocytic leukemia or to identify a subject to be treated with an inhibitor of HAT and / or an inhibitor of EZH2 by determining the acetylation or methylation status of specific relevant regions and relative kit and microarray. The invention also refers to histone acetyl transferase (HAT) inhibitor for use in the treatment of a solid or hematopoietic tumor.

Specifically, provided were the followings: an agent for preventing and / or treating hematologic malignancies comprising as an active ingredient at least one peptide having an amino acid sequence selected from any one of SEQ ID NOs: 1 to 10 in the sequence listing; the agent for preventing and / or treating hematologic malignancies further comprising an adjuvant; and the preventing and / or treating agent to use as a cancer vaccine for hematologic malignancies, which allowed prevention and / or treatment of hematologic malignancies such as an HLA-A24 positive hematologic malignancies or the hematologic malignancies that are HLA-A24 positive and express a protein containing the peptide.

The invention provides an application of lappaconitine or 12-epi-lappaconitine in preparation of a medicine for treating leukemia, which belongs to the field of medicines. Researches of the inventor and find that both lappaconitine and 12-epitope-lappaconitine can effectively inhibit the proliferation of leukemia cells, can also promote the apoptosis of leukemia cells, and particularly have a moreremarkable effect on myeloid leukemia cells. Therefore, both lappaconitine and 12-epi-lappaconitine have anti-leukemia and anti-hematopoietic tumor activity, can be independently or jointly used as amedicine for treating anti-leukemia and anti-hematopoietic tumors, and are wide in application prospect.
