Recent work by Fernandez-Sanchez and coworkers examining the impact of applied pressure on the malignant phenotype of murine colon tissue in vivo revealed that mechanical perturbations can drive malignant behavior in genetically normal cells. Their findings build upon an existing understanding of how the mechanical cues experienced by cells within a tissue become progressively modified as the tissue transforms. Using magnetically stimulated ultra-magnetic liposomes to mimic tumor growth -induced solid stress, Fernandez-Sanchez and coworkers were able to stimulate beta-catenin to promote the cancerous behavior of both a normal and genetically modified colon epithelium. In this perspective, we discuss their findings in the context of what is currently known regarding the role of the mechanical landscape in cancer progression and beta-catenin as a mechanotransducer. We review data that suggest that mechanically regulated activation of beta-catenin fosters development of a malignant phenotype in tissue and predict that mechanical cues may contribute to tumor heterogeneity.
