The present invention relates to phosphodiesterase 9A (PDE9A) for use as a marker for prostate cancer, and the use of PDE9A as a marker for diagnosing, detecting, monitoring or prognosticating prostate cancer or the progression of prostate cancer. The present invention also relates to a composition for diagnosing, detecting, monitoring or prognosticating prostate cancer or the progression of prostate cancer, a corresponding method and immunoassay, a method for diagnosing, monitoring or prognosticating hormone-resistant prostate cancer vs. hormone-sensitive prostate cancer, a corresponding immunoassay, a method of data acquisition, an immunoassay for diagnosing, detecting, monitoring or prognosticating prostate cancer or the progression of prostate cancer, a method of identifying an individual for eligibility for prostate cancer therapy, an immunoassay for stratifying an individual or cohort of individuals with a prostate cancer disease, an immunoassay for stratifying an individual with prostate cancer. The present invention further envisages pharmaceutical compositions and their use for the treatment of prostate cancer, in particular hormone-resistant prostate cancer.

Phosphodiesterase 9A as prostate cancer marker

The present invention relates to phosphodiesterase 4D7 (PDE4D7) for use as a marker for malignant, hormone-sensitive prostate cancer, wherein the expression of the marker is increased when comparing the expression in malignant, hormone-sensitive prostate cancer tissue, to the expression in normal tissue or benign prostate tumor tissue, and the use of PDE4D7 as a diagnostic marker for malignant, hormone-sensitive prostate cancer. The present invention also relates to a composition for diagnosing, detecting, monitoring or prognosticating malignant, hormone-sensitive prostate cancer, a corresponding detection method, a method allowing to discriminate between a benign and malignant hormone-sensitive prostate cancer and a method of data acquisition, as well as corresponding immunoassays. The present invention also relates to a method of identifying an individual for eligibility for malignant, hormone-sensitive prostate cancer as well as an immunoassay for stratifying an individual with such prostate cancer. The present invention further envisages pharmaceutical compositions and their use for the treatment of malignant, hormone-sensitive prostate cancer.
