The cellular and molecular basis of stromal cell recruitment, activation and crosstalk in carcinomas is poorly understood, limiting the development of targeted anti-stromal therapies. In mouse models of triple negative breast cancer (TNBC), Hedgehog ligand produced by neoplastic cells reprograms cancer-associated fibroblast (CAF) to provide a supportive niche for the acquisition of a chemo-resistant, cancer stem cell (CSC) phenotype via FGF5 expression and production ...

A current challenge in cancer therapeutics is incomplete response to treatment and emergence of therapy-resistant disease. Androgen deprivation therapy (ADT), the standard treatment for advanced prostate cancer, and effectively reduces the tumour burden in most patients. Yet, residual tumour cells that withstand ADT eventually develop lethal castration-resistance. Eliminating these castrate-tolerant cells, by combining ADT with other treatments, might delay or even prevent cas...
