Abstract: An object of the present invention is to provide a method for determining whether a subject suffers from malignant lymphoma or leukemia and an agent for treating and/or preventing the disease. The present invention relates to a method for assisting in determining whether a subject suffers from, or is likely to suffer from malignant lymphoma or leukemia, comprising: a detection step of detecting at least one of a fusion mutation of a DUX4 gene, an overexpression of a DUX4 gene, and a fusion mutation of an MEF2D gene; and a determination step of determining that the subject suffers from or is likely to suffer from the disease when at least one of the fusion mutations or the overexpression is detected. Moreover, the present invention relates to a pharmaceutical composition comprising a DUX4 inhibitor as an active ingredient, for treating and/or preventing malignant lymphoma or leukemia in a subject having a fusion mutation of a DUX4 gene and an IGH or IGL gene and/or overexpression of a DUX4 gene.

Abstract: The invention is intended to further improve the operability, economic efficiency and safety in the preparation of antigen-specific CTLs. The invention provides a preparation kit used for a method for preparing antigen-specific cytotoxic T lymphocytes, the method comprising: a first step for inducing antigen-specific cytotoxic T lymphocytes, wherein the components of the first step include a culture medium contained in an injection vessel, a hermetically scaled culture vessel, and the like; a second step for preparing an activated T cell for antigen presentation, wherein the components of the second step include a culture medium contained in an injection vessel, a hermetically sealed culture vessel, and the like.; and a third step for proliferating antigen-specific cytotoxic T lymphocytes, wherein the components of the third step include a culture medium contained in an injection vessel, a hermetically sealed separation vessel, a hermetically sealed culture vessel, and the like.

Abstract: It is intended to provide a tool, a procedure and so on which are useful in developing a therapeutic strategy efficacious in inhibiting or overcoming the resistance against a CD20-directed molecular-targeted drug. Thus, a CD20-negatively converted B-cell malignant lymphocyte cell line is provided. Also, a model animal indicating the pathological conditions of CD20-negatively converted B-cell malignant lymphocyte is provided. Further, a method of screening a substance, which is efficacious against CD20-positive B-cell malignant lymphocyte or CD20-negatively converted B cell malignant lymphocyte, is provided. Furthermore, a drug against CD20-positive B-cell malignant lymphocyte or CD20-negatively converted B-cell malignant lymphocyte, which is characterized by being used together with a CD20-directed molecular-targeted drug, is provided. In one embodiment, a DNA methylase inhibitor or a histone deacetylase inhibitor is employed as the active ingredient.

Abstract: Investigation on the frequency of FLT3/ITD found in various blood cancers has revealed that the frequency is high in acute myeloblastic leukemia in particular. Studies on the effects of FLT3/ITD in the blood cell lines revealed that the tyrosine residues in FLT3/ITD is constitutively phosphorylated in these cell lines and that blood cells into which FLT3/ITD is introduced show IL-3 independent proliferation. Moreover, the blood cells into which FLT3/ITD is introduced are found to be capable of forming tumors and inhibit cell differentiation. The inventors have found that it is possible to screen for pharmaceutical compounds against tumors by using inhibition of these FLT3/ITD functions as an index.
