Foxm1 peptides and vaccines containing the same

Abstract

The present invention provides isolated peptides having the amino acid sequence of SEQ ID NO: 34 or fragments thereof, which bind to HLA antigen and induce cytotoxic T lymphocyte (CTL). The present invention further provides peptides which include one, two, or several amino acid insertions, substitution or addition to the aforementioned peptides or fragments, but still have the cytotoxic T cell inducibility. Further provided are nucleic acids encoding any of these aforementioned peptides as well as pharmaceutical substances or compositions including any of the aforementioned peptides or nucleic acids. The peptides, nucleic acids, pharmaceutical substances or compositions of the present invention may be used for treating cancer or tumor.

Description

technical field [0001] priority [0002] This application claims the benefit of US Provisional Application No. 61 / 153,408, filed February 18, 2009, the entire contents of which are incorporated herein by reference. [0003] The present invention relates to the field of biological sciences, more specifically to the field of cancer treatment. Specifically, the present invention relates to novel peptides that are extremely effective as cancer vaccines, and drugs for treating and preventing tumors. Background technique [0004] It has been demonstrated that CD8-positive CTLs can recognize epitope peptides derived from tumor-associated antigens (TAAs) on major histocompatibility complex (MHC) class I molecules, and then kill tumor cells. Since the discovery of the first example of TAA, the melanoma antigen (MAGE) family, many other TAAs have been discovered by immunological means (NPL 1: Boon T, Int J Cancer 1993 May 8, 54(2): 177 -80; NPL2: Boon T & van der Bruggen P, J Exp ...
