Abstract: The present invention aims to elucidate a polynucleotide as a novel responsible gene for cancer and aims to thus provide a method for detecting the polynucleotide and a polypeptide encoded by the polynucleotide and a detection kit, a probe set, and a primer set for the detection. The present invention also aims to provide a pharmaceutical composition for treating cancer. The method detects a fusion gene composed of a portion of an FGFR3 gene and a portion of a TACC3 gene or a fusion protein encoded by the fusion gene. The primer set, the probe set, or the detection kit comprises a sense primer and a probe set designed from the portion encoding FGFR3 and an antisense primer and a probe set designed from the portion encoding TACC3. Since an inhibitor of the polypeptide exhibits antitumor effect, a pharmaceutical composition for treating cancer which is positive for either the fusion gene or the polypeptide is provided.

Abstract: [Problem] To provide an anti-human PAI-1 antibody for preventing or treating pulmonary fibrosis by binding to active human PAI-1 and inhibiting effects mediated by the active human PAI-1. [Means for Solution] The present inventors have investigated anti-PAI-1 antibodies and consequently have provided an anti-human PAI-1 antibody comprising a heavy chain variable region consisting of the amino acid sequence of amino acid numbers 1 to 118 of SEQ ID NO: 2 and a light chain variable region consisting of the amino acid sequence of amino acid numbers 1 to 108 of SEQ ID NO: 4.

Abstract: Novel anti-human CTGF antibodies having excellent binding activity and/or neutralizing activity, as compared with conventional anti-human CTGF antibodies, are useful for treating various diseases in which human CTGF is involved in pathogenesis, including renal diseases such as chronic kidney disease and diabetic nephropathy.

Abstract: [Problem] An object of the present invention is to provide an anti-human CTGF antibody having excellent binding activity and/or neutralizing activity, as compared with conventional anti-human CTGF antibodies, and means for preventing or treating various diseases in which human CTGF is involved in pathogenesis, including renal diseases such as chronic kidney disease and diabetic nephropathy, using the anti-human CTGF antibody. [Means for Solution] An anti-human CTGF antibody includes: a heavy-chain variable region consisting of the amino acid sequence shown by SEQ ID NO: 10; and a light-chain variable region consisting of the amino acid sequence shown by SEQ ID NO: 4.

Abstract: A method of screening for an antidiabetic agent comprising (1) bringing a test substance into contact with a cell which overexpresses a polypeptide exhibiting an activity of suppressing insulin secretion under a high glucose concentration by an overexpression of the polypeptide in pancreatic ? cells, and comprising an amino acid sequence of SOCS-2 or a modified or homologous amino acid sequence thereof, under a high glucose concentration, and (2) measuring an amount of insulin secreted from the cell, or (1) bringing a test substance into contact with a cell transformed with a DNA fragment comprising a human SOCS-2 promoter sequence or a modified sequence thereof, (2) measuring an amount of expressed SOCS-2, and (3) selecting a substance which suppresses the amount of expressed SOCS-2, is disclosed.
