Abstract: The present invention relates to a novel tumor-specific polypeptide and use thereof. In particular, the present invention relates to a tumor-specific polypeptide having high affinity for HLA-A0201 and having cytotoxic T lymphocyte inducing ability, and its use for diagnosing, preventing and treating diseases (especially cancer) associated with high expression of the TWISTNB gene or mutation(s) in the TWISTNB gene.

Abstract: Provided are a tumour antigen polypeptide having the amino acid sequence as shown in SEQ ID NO: 2 or a variant thereof; a nucleic acid encoding same; a nucleic acid construct, an expression vector, and a host cell comprising the encoding nucleic acid; and an antigen presenting cell presenting the tumour antigen polypeptide on the cell surface and an immune effector cell thereof. Also provided is the use of the polypeptide, nucleic acid, antigen presenting cell or immune effector cell in the diagnosis, prevention and treatment of cancers.

Abstract: Provided are a polypeptide and nucleic acid for encoding the polypeptide, a nucleic-acid construct, an expression vector, and a host cell containing the nucleic acid, an antigen-presenting cell presenting the polypeptide on the surface of the cell, and immune effector cell thereof, a pharmaceutical composition containing the polypeptide, a vaccine containing the nucleic acid, the nucleic acid construct, the expression vector, the host cell, the antigen-presenting cell, and the immune effector cell, and an antibody recognizing the polypeptide. Also provided is a therapeutic method using the polypeptide, the nucleic acid, the pharmaceutical composition, the vaccine, and the antibody. Also provided are a diagnosis method and diagnosis apparatus for detecting the described polypeptide. Also provided is an application of the polypeptide in preparing a vaccine, a tumor diagnosis kit, or a pharmaceutical composition, and an application of the polypeptide or the nucleic acid as a test target in tumor diagnosis.
