Role of Wnt signalling in advanced prostate cancer.

Recent next-generation sequencing studies demonstrate that multiple pathways are often deregulated in advanced and metastatic prostate cancer (PC). In a recent issue of The Journal of Pathology, an elegant study by Jefferies et al used in vivo modelling to demonstrate how activation of the PI3K, WNT, and MAPK pathway converges on mTORC1 signalling to drive aggressive disease. The study also highlights that approaches to target advanced PC require intelligent combination of agents to target single/multiple signalling pathways in combination with androgen receptor (AR) blockade.
