A recent Cell publication demonstrates that the secreted antagonist of transforming growth factor-beta ligands, Coco, can re-activate previously dormant metastatic breast cancer cells specifically in the lung by inhibiting bone morphogenetic protein (BMP) signaling. The authors provided evidence for a connection between Coco/BMP signaling and molecular and cellular traits of cancer stem cells. Their findings represent a significant advance in our understanding of metastatic dormancy, an extremely important clinical issue that remains understudied. Equally as important, this study also opens interesting avenues for future research.
