It is unclear how specific signalling pathways are coordinated to generate pathologically activated cancer associated fibroblasts (CAFs). Here, Ferrari et al show that stromal expression of Dickkopf-3 (DKK3) associates with aggressive tumours. DKK3 is a HSF-1 effector that activates β-catenin and YAP/TAZ, and DKK3-driven YAP/TAZ activation regulates the pro-tumorigenic behaviour of CAFs.
