Figure 1 IKKα and Maspin in Prostate Cancer Metastasis
The metastasis suppressor gene maspin is highly expressed in early prostate tumor cells. Following infiltration of RANKL-producing immune cells, RANK phosphorylates and activates IKKα, inducing its nuclear translocation and interaction with the maspin promoter causing its transient repression. This gene is then silenced by methylation, committing prostate cancers to a metastatic fate. Activation of RANK on prostate cancer cells requires either close contact with RANKL-expressing immune cells, cleavage of the RANKL extracellular domain by proteases such as MMP-7, or alternatively, immune cell expression of a secreted form of RANKL.
