Prostate stromal cells can contribute to prostate tumorigenesis. Here the authors show that the loss of androgen receptor signalling in Gli1-lineage stromal cells diminishes prostate epithelial oncogenic transformation and tumor growth in mouse models and this is due to insulin-like growth factor binding protein 3-mediated inhibiting IGF1 and Wnt/β-catenin signalling activation.
