Classically known for its indispensible role in embryonic development, the Notch signalling pathway is gaining recognition for its regulation of adult tissue homoeostasis and aberrant activation in disease pathogenesis. The pathway has been implicated in cancer initiation and development, as well as early stages of cancer progression by regulating conserved cellular programs such as the epithelial-to-mesenchymal transition. We recently extended the role of Notch signalling to late stages of tumour progression by elucidating a stroma-dependent mechanism for the pathway in osteolytic bone metastasis. Of clinical significance, disrupting the Notch pathway and associated molecular mediators of Notch-dependent bone metastasis may provide novel therapeutic strategies to combat aggressive bone metastatic disease.
