In a mouse model of prostate cancer it is found that that the TGF-β signalling pathway limits tumour progression and metastasis. Using markers of this pathway and other biologically relevant factors, a four-gene signature is identified that is associated with poorer clinical outcome and metastatic progression in several prostate cancer cohorts, especially in combination with other clinical parameters. This signature may prove useful for the development of a better prognostic test for those cases of prostate cancer in which deciding on the right treatment regime while avoiding over-treatment constitutes an important clinical challenge.
