1. A method of determining the likelihood of prostate cancer recurrence in a subject comprising,
providing a biological sample from the subject comprising prostate cancer cells characterized as having a Gleason score of 6 to 7; and
determining the percentage of prostate cancer cells expressing detectable levels of Pin1 polypeptide in the sample by detecting the binding of an antibody that specifically binds to a Pin1 polypeptide consisting of the amino acid sequence set forth in SEQ ID NO: 1, or an antigen binding fragment thereof,
wherein the percentage of prostate cancer cells in the sample positive for antibody binding is indicative of the likelihood of prostate cancer recurrence in the subject.
