Nuclear cytokine-activated IKKα controls prostate cancer metastasis by repressing Maspin

Nuclear cytokine-activated IKKα controls prostate cancer metastasis by repressing Maspin Experiments in a mouse prostate cancer model have identified a signalling pathway that stimulates the formation of metastases. The pathway is initiated when a protein ligand occupies a receptor known as RANK (receptor activator of nuclear factor κB), and is dependent on the activation and nuclear translocation of IKKα (IκB kinase α). Once in the nucleus, activated IKKα represses maspin gene transcription, whose product is well established as an inhibitor of cell migration and invasion in prostate and breast cancer. RANK may therefore be a general promoter of metastatic behaviour in prostate or mammary carcinoma cells. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nature Springer Journals

Abstract

Experiments in a mouse prostate cancer model have identified a signalling pathway that stimulates the formation of metastases. The pathway is initiated when a protein ligand occupies a receptor known as RANK (receptor activator of nuclear factor κB), and is dependent on the activation and nuclear translocation of IKKα (IκB kinase α). Once in the nucleus, activated IKKα represses maspin gene transcription, whose product is well established as an inhibitor of cell migration and invasion in prostate and breast cancer. RANK may therefore be a general promoter of metastatic behaviour in prostate or mammary carcinoma cells.
