  • Publication number: 20230192890
    Abstract: Provided are anti-PAD4 antibodies having excellent properties and an excellent method for treatment of RA. Used are anti-PAD4 antibodies that specifically bind to an epitope containing positions 345, 347, and 348 of PAD4. These anti-PAD4 antibodies may inhibit the citrullination activity of PAD4. In addition, these anti-PAD4 antibodies may have a KD (M) of 9.0×10?9 or less. Optionally, the anti-PAD4 antibody and a TNF? inhibitor are used in combination.

  • Publication number: 20210340275
    Abstract: The present invention relates to an esophageal cancer marker and application thereof. The present invention relates to: a marker that includes Glypican-1 or an expression product thereof, or a fragment or derivative thereof, and serves to identify esophageal cancer; a detection agent that includes a substance that binds to Glypican-1 or an expression product thereof; and a composition that includes a Glypican-1 inhibitor and serves to prevent or treat esophageal cancer. Herein, Glypican-1 can be SEQ ID NO: 1 (nucleic acid sequence) or SEQ ID NO: 2 (amino acid sequence), or an equivalent thereof.

  • Publication number: 20170051056
    Abstract: The present invention makes it possible to obtain a novel therapeutic drug for malignant tumors. Specifically, the present invention provides a therapeutic drug for malignant tumors, said drug including an anti-LSR (lipolysis stimulated lipoprotein receptor) antibody or an antigen-binding fragment thereof, or a functional equivalent thereof, or an LSR inhibitor such as a nucleic acid. Said inhibitor uses a therapeutic drug for malignant tumors, said drug including an anti-LSR antibody, or an antigen-binding fragment thereof or a functional equivalent thereof. The inhibitor may also be an LSR antagonist. The abovementioned therapeutic drug may be administered to patients in whom the onset of an LSR-positive malignant tumor is judged to have occurred.
