Aggressive types of breast cancer often exhibit constitutive activation of the pro-inflammatory transcription factor NF-κB. Here, Yamamoto et al. show that, in basal-like breast cancer, NF-κB upregulates the Notch receptor ligand JAG1 in non-cancer stem cells and thereby induces proliferation of breast cancer stem cells.
