Abstract:
Isolated CDCA1-derived epitope peptides having Th1 cell inducibility are disclosed herein. Such peptides can be recognized by MHC class II molecules and induce Th1 cells. In preferred embodiments, such a peptide of the present invention can promiscuously bind to MHC class II molecules and induce CDCA1-specific cytotoxic T lymphocytes (CTLs) in addition to Th1 cells. Such peptides are thus suitable for use in enhancing immune response in a subject, and accordingly find use in cancer immunotherapy, in particular, as cancer vaccines. Also disclosed herein are polynucleotides that encode any of the aforementioned peptides, APCs and Th1 cells induced by such peptides and methods of induction associated therewith. Pharmaceutical compositions that comprise any of the aforementioned components as active ingredients find use in the treatment and/or prevention of cancers or tumors.

Abstract:
According to the present invention, peptides having the amino acid sequence of SEQ ID NOs: 14, 21, 23, 27, 36, 46, 57, 60 and 62 were demonstrated to have cytotoxic T lymphocyte (CTL) inducibility. Therefore, the present invention provides a peptide having the amino acid sequence selected from among SEQ ID NOs: 14, 21, 23, 27, 36, 46, 57, 60 and 62. The peptide can include one, two, or several amino acid substitutions, deletions, insertions, or additions so long as its CTL inducibility is retained. Furthermore, the present invention provides pharmaceutical agents for the treatment and/or prophylaxis of cancers, and/or prevention of postoperative recurrence thereof, which contain any of these peptides. Pharmaceutical agents of this invention include vaccines.

Abstract:
The present application provides novel human genes A7322, whose expression is markedly elevated in breast cancer. The present application also provides human genes F3374 whose expression is markedly elevated in breast cancer. These genes and polypeptides encoded thereby can be used, for example, in the diagnosis of breast cancer, and as target molecules for developing drugs against breast cancer. The invention features methods of screening for modulators of the kinase activity of PBK/TOPK. The invention further provides methods of screening for agents to prevent or treat cancer, such as breast cancer.
