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.

Methods for treating cancer by inhibiting FGFR3/TACC3 fusion protein

[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.

Anti-human PAI-1 antibody

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.
