Anti-Depressant Therapy Brightens the Outlook for Prostate Cancer Bone Metastases

Abstract

In this issue of Cancer Cell, Wu et al. identify MAOA as a key mediator of osteolytic bone responses that involve complex paracrine interactions between tumor cells, osteoblasts, and osteoclasts. Pharmacological inhibition of MAOA enzymatic activity effectively interrupted osteolysis and metastatic progression in preclinical models, suggesting a new treatment opportunity.
