Targeting extracellular matrix (ECM) remodelling is a feasible avenue to prevent cancer aggressiveness and metastasis. In this study, Kay et al. show that metabolic flux in cancer-associated fibroblasts is coupled to enhanced proline synthesis by PYCR1 to support elevated production of collagen-rich ECM, thus contributing to cancer spreading.
