Abstract: An objective of the present invention is to provide a means for enabling cancer immunotherapy that targets approximately 30% of various cancer patients that highly express forkhead box M1 (FOXM1) among the Japanese, by identifying FOXM1-derived peptides that can activate cancer cell-damaging human killer T cells by binding to HLA-A2. The present invention provides a peptide of (A) or (B) below: (A) a peptide including the amino acid sequence of any one of SEQ ID NOs: 1 to 3; (B) a peptide which includes the amino acid sequence of any one of SEQ ID NOs: 1 to 3, wherein one, two, or several amino acid(s) are substituted, deleted, inserted, and/or added, and wherein the peptide shows cytotoxic (killer) T cell-inducing activity.

Abstract: The present invention provides a peptide of the following (A) or (B): (A) a peptide including an amino acid sequence of SEQ ID NO: 1 or 2; (B) a peptide including an amino acid sequence of SEQ ID NO 1 or 2, wherein one, two, or several amino acid(s) are substituted, deleted, inserted, and/or added, and wherein the peptide has an activity to induce killer T cells.

Abstract: The present invention provides the peptide of (A) or (B) below, and methods of using the peptide: (A) a peptide including the amino acid sequence of SEQ ID NO: 1 or 2, (B) a peptide which includes the amino acid sequence of SEQ ID NO: 1 or 2, wherein one, two, or several amino acid(s) are substituted, deleted, inserted, and/or added, and wherein the peptide shows killer T cell-inducing activity.

Abstract: An object of the present invention is to provide a novel and clinically useful diagnostic agent for malignant melanoma. The present invention provides a diagnostic agent for malignant melanoma, which comprises an antibody against GPC3, or a probe or a primer capable of detecting GPC3 expression.

Abstract: It is an objective of the present invention to identify SPARC protein-derived peptides that are able to induce human killer T cells and helper T cells having cytotoxic activity to tumors, and to provide a means for carrying out a tumor immunotherapy of patients with various types of cancers overexpressing SPARC. The present invention provides a peptide of any of the following: (A) a peptide which consists of the amino acid sequence as shown in any one of SEQ ID NOS: 1 to 3; or (B) a peptide which consists of an amino acid sequence comprising a substitution or addition of one or several amino acids with respect to the peptide consisting of the amino acid sequence as shown in any one of SEQ ID NOS: 1 to 3, and which has capacity to induce cytotoxic (killer) T cells.

Abstract: It is an object of the present invention to identify a glypican-3-derived peptide which can bind to HLA-A2 and activate human killer T cells, so as to provide a means for carrying out an immunotherapy which is able to target approximately 40% of Japanese patients suffering from several types of cancers, which express GPC3 at a high level. The present invention provides a peptide of any of the following (A) or (B): (A) a peptide, which has the amino acid sequence as shown in any one of SEQ ID NOS: 1 to 3; or (B) a peptide, which has an amino acid sequence comprising a substitution or addition of one or two amino acids with respect to the amino acid sequence as shown in any one of SEQ ID NOS: 1 to 3, and which has ability to induce killer T cells.

Abstract: The object of the present invention is to find out another tumor marker which is useful for early diagnosis of melanoma, and provide a diagnostic kit and diagnostic method for malignant melanoma using such marker. The present invention provides a diagnostic kit for malignant melanoma, which comprises an antibody against SPARC and an antibody against GPC3.

Abstract: An object of the present invention to provide: a human pancreatic cancer antigen and/or a human colon cancer antigen that can be applied to the diagnosis and/or treatment of various types of cancers or tumors including pancreatic cancer and colon cancer as representative examples; a gene encoding the same; an anti-cancer vaccine using the same; or the like. The present invention provides a cancer antigen comprising a protein having the amino acid sequence shown in SEQ ID NO: 1; a peptide comprising a portion of said protein and having immune-stimulating activity; an anti-cancer vaccine comprising said peptide; a DNA having the nucleotide sequence shown in SEQ ID NO: 2, or its complementary sequence or a part or full length of these sequence; an anti-cancer vaccine comprising said DNA; and use thereof.
