Compositions and methods for the detection and therapy of breast cancer are
disclosed. The compounds provided include nucleotide sequences that are
preferentially expressed in breast tumor tissue, as well as polypeptides
encoded by such nucleotide sequences. Vaccines and pharmaceutical
compositions comprising such compounds are also provided and may be used,
for example, for the prevention and treatment of breast cancer. The
polypeptides may also be used for the production of antibodies, which are
useful for diagnosing and monitoring the progression of breast cancer in a
patient.
