摘要:
A molecular marker for detecting a cancer stem cell in a cell mass which is a subject of interest, wherein the molecular marker can be detected in a cancer stem cell contained in the subject of interest but cannot be detected in a normal cell and a cancer cell that is different from a cancer stem cell; a method for determining the presence or absence of a cancer stem cell in a subject of interest by using the molecular marker as an measure; a kit for determining the presence or absence of a cancer stem cell, which comprises at least a reagent for detecting the molecular marker; a polypeptide encoded by the molecular marker; an antibody capable of recognizing an epitope of an expression product of a gene derived from the molecular marker; a nucleic acid capable of inhibiting the expression of the molecular marker; and a nucleic acid vaccine comprising a gene derived from the molecular marker.
摘要:
The purpose of the present invention is to provide: a detection agent for specifically detecting a cancer stem cell; a tumor antigen peptide specifically presented by cancer stem cells; a medicinal composition useful in preventing and/or treating cancer, said medicinal composition comprising the aforementioned tumor antigen peptide as an active ingredient; a method for screening the tumor antigen peptide; etc. To achieve the above-mentioned purpose, provided are: peptides represented by Y o -X o -Z o ; a polyepitope peptide consisting of a plurality of epitope peptides connected together, said polyepitope peptide containing at least one of the above-mentioned peptides as one of the epitope peptides; a polynucleotide encoding the aforementioned peptides and/or polyepitope peptide; a medicinal composition comprising the same as an active ingredient; a prophylactic and/or therapeutic agent for cancer characterized by inducing CTL; etc.
