This explains why prostate tumors subjected to androgen ablation experience an increase in Akt phosphorylation, and suggest that the tumor compensates for the loss of one pathway with another. Different modes of interaction between the two pathways, including direct interaction, or regulation via downstream intermediates, such as the wnt/GSK-3beta/beta-catenin pathway, NF-kappaB, and the FOXO family of transcription factors, will be discussed.
