  • Publication number: 20200385812
    Abstract: The FGFR-encoding gene was studied extensively with regard to its expression, hyperamplification, mutation, translocation, or such in various cancer cells. As a result, novel fusion polypeptides in which the FGFR3 polypeptide is fused with a different polypeptide were identified and isolated from several types of bladder cancer-derived cells and lung cancer cells. The use of a fusion polypeptide of the present invention as a biomarker in FGFR inhibitor-based cancer therapy enables one to avoid side effects in cancer therapy and control the therapeutic condition to produce the best therapeutic effect, thereby enabling individualized medicine.

  • Publication number: 20200385686
    Abstract: The purpose of the present invention is to provide: a cancer stem cell mass from which cells incapable of forming cancer are substantially removed and which has a characteristic property of reproducing a layered structure of a cancer tissue; a process for producing the cancer stem cell mass; and use of the cancer stem cell mass. For achieving the purpose, the present inventors grew a human cancer tissue repeatedly in a NOG mouse, separated cancer cells from the grown cancer tissue, and made a comparison of various cancer cell culture processes with each other. As a result, a cancer stem cell composition which is homogeneous and is substantially free of the coexistence of cells capable of forming cancer and cells incapable of forming cancer in a mixed state can be produced successively by employing an attached culture process using a serum-free stem cell culture medium rather than a generally employed floating culture process, and consequently the present invention has been accomplished.

  • Patent number: 10815489
    Abstract: The present invention provides modified aminoacyl-tRNA synthetases (ARSs) having increased reactivity with N-methyl amino acids compared to natural aminoacyl-tRNA synthetases. The modified aminoacyl-tRNA synthetases according to the present invention can aminoacylate tRNAs with their corresponding N-methyl-substituted amino acids such as N-methyl-phenylalanine, N-methyl-valine, N-methyl-serine, N-methyl-threonine, N-methyl-tryptophan, and N-methyl-leucine more efficiently than natural aminoacyl-tRNA synthetases. The present invention enables a more efficient production of polypeptides containing N-methyl amino acids.

  • Publication number: 20200332001
    Abstract: The present inventors have successfully prepared an antigen-binding molecule comprising an antibody variable region that has binding activity against a molecule expressed on the surface of a T cell and a molecule expressed on the surface of any other immunocyte, but does not bind to these molecules at the same time. The present invention allows the preparation of an antigen-binding molecule capable of circumventing adverse reactions that may be caused by the cross-linking of T cells to other immunocytes, and provides an antigen-binding molecule suitable as a drug.

  • Publication number: 20200325222
    Abstract: An objective of the present invention is to obtain two types of substantively homogeneous cancer stem cell populations which can be characterized using the cell surface marker Lgr5, and to provide cancer therapeutics using an antibody against a cell membrane molecule specifically expressed in these cancer stem cells by identifying said cell membrane molecule. A further objective is to provide, using an antibody against a cell membrane molecule specifically expressed in cancer stem cells, a reagent for detecting cancer stem cells, and a method for diagnosing and sorting cancer patients. The present inventors discovered that highly pure large intestine cancer stem cells (CSC) can be obtained in a large quantity, and identified the two types of conditions of large intestine CSCs distinguishable through Lgr5 expression. Moreover, the present inventors discovered that an antibody against a cell membrane molecule specifically expressed in said cancer stem cells can damage said cells.

  • Publication number: 20200317790
    Abstract: The antibodies of the present invention have specific binding activity to HLA-DQ2.5 and may have binding activity to HLA-DQ2.2 and/or HLA-DQ7.5, but substantially no binding activity to HLA-DQ8, HLA-DQ5.1, HLA-DQ6.3, HLA-DQ7.3, HLA-DR, HLA-DP, or a complex of the invariant chain (CD74) and HLA-DQ2.5. The antibodies bind to HLA-DQ2.5 in the presence of a gluten peptide such as gliadin, i.e., bind to HLA-DQ2.5 forming a complex with the gluten peptide. The antibodies have neutralizing activity against the binding between HLA-DQ2.5 and TCR, and thus block the interaction between HLA-DQ2.5 and an HLA-DQ2.5-restricted CD4+ T cell. The antibodies do not undergo rapid internalization mediated by the invariant chain.

  • Patent number: 10782300
    Abstract: The present invention discloses a method for determining the efficacy of GPC3-targeting drug therapy for cancer in a patient before the start of GPC3-targeting drug therapy or a patient or determining the continuation of GPC3-targeting drug therapy for a patient, including monitoring a concentration of free GPC3 in a biological sample isolated from the patient before the start of GPC3-targeting drug therapy and/or the patient treated with the GPC3-targeting drug therapy, wherein when the concentration of free GPC3 is a predetermined value, the efficacy of the GPC3-targeting drug therapy is determined or the continuation of the GPC3-targeting drug therapy is determined. The present invention also discloses a GPC3-targeting drug or a preparation which is to be further administered to a patient for which the efficacy of the GPC3-targeting drug therapy has been determined or the continuation of the GPC3-targeting drug therapy has been determined.

  • Patent number: 10782290
    Abstract: According to the present invention, the amount of a plasmablast (PB) in a sample of a relapsing-remitting multiple sclerosis (RRMS) patient can be measured, thereby predicting the therapeutic effect of interferon beta (IFN-?) or predicting a RRMS case for which the continuous administration of IFN-? is difficult due to the manifestation of a serious adverse reaction or the aggravation of concomitant immune disorder. In addition, the amount of PB in a sample of a RRMS patient can also be measured, thereby predicting the therapeutic effect of an IL-6 inhibitor in the treatment of RRMS. As a result, a treatment method effective for patients not suitable for IFN-? in the treatment of RRMS can be provided.
