Compositions and methods for preventing or treating cancer
The present invention relates to a MUC1 cytoplasmic tail peptide or portion thereof. These peptides are useful for inducing an immune response to MUC1-expressing tumor cells and thus for preventing or treating cancer.
1. A composition comprising a MUC1 cytoplasmic tail peptide, wherein said MUC1 cytoplasmic tail peptide consists of a 9 to 15 amino acid portion of SEQ ID NO: 48, and wherein said MUC1 cytoplasmic tail peptide comprises a sequence selected from the group consisting of SEQ ID NO: 22, SEQ ID NO: 24, SEQ ID NO: 42, SEQ ID NO: 45, and SEQ ID NO: 46.
2. The composition of claim 1 , further comprising at least one additional MUC1 cytoplasmic tail peptide consisting of a 9 to 15 amino acid portion of SEQ ID NO: 1.
3. The composition of claim 2 , wherein said additional MUC1 cytoplasmic tail peptide consists of a 9 to 15 amino acid portion of SEQ ID NO: 47.
4. The composition of claim 2 , wherein said additional MUC1 cytoplasmic tail peptide consists of a 9 to 15 amino acid portion of SEQ ID NO: 49.
5. The composition of claim 1 , wherein said composition comprises more than one of said MUC1 cytoplasmic tail peptides.
6. The composition of claim 1 further comprising a carrier protein.
