Abstract: Disclosed herein is a novel gene signature of metastatic cancer cells and a novel three-dimensional (3D) culture system for use in improved methods of predicting metastasis or prognosis in cancer. Accordingly, described herein are methods of determining a risk of metastasis, methods of predicting prognosis for cancer patients, methods of treating a cancer patient identified at high risk of metastasis, methods of treating a cancer patient identified as having poorer prognosis, methods for determining the migration capacity of a tumor, methods of screening a tumor for sensitivity to a drug, and kits for use in performing these methods.

Abstract: Methods of treating cancer, including methods that administer to a patient an agent that may be an inducer of cancer stem cell differentiation and mesenchymal to epithelial transition (MET) in multiple tumor cell lines in a 3D culture model that recapitulates clinically relevant tumor cell states in vitro. The differentiating activity of the agents in cancer stem cells may occur through over-activation, rather than inhibition, of the Notch pathway. Methods of screening agents, and pharmaceutical compositions.
