Aberrant androgen action in prostatic progenitor cells induces oncogenesis and tumor development through IGF1 and Wnt axes

Activation of the androgen receptor (AR) through androgen binding is essential for prostate tumorigenesis. Here the authors show that AR activation in a subpopulation of prostatic progenitor cells can initiate prostatic intraepithelial neoplasia formation and promotes prostate cancer development through activation of IGF1 and Wnt/β-catenin signalling pathways.
