Mechanobiology of Cancer Cell Metastasis

The mechanobiology of cancer cell metastasis examines how physical forces and the mechanical properties of cells and their microenvironment govern each step of the metastatic cascade. Tumour cells respond to extracellular matrix rigidity, fluid shear stress and interstitial pressure by activating mechanotransduction pathways that influence adhesion, migration, survival and invasion. Integrin‐mediated adhesion complexes and actomyosin contractility enable cells to sense matrix stiffness and generate traction forces, driving invasion through three-dimensional interstitial spaces. Circulating tumour cells are exposed to haemodynamic shear forces that selectively trigger adaptive responses or cell death, while interactions with the endothelium and subendothelial extracellular matrix determine arrest, transendothelial migration and organ tropism. Within secondary sites, mechanical cues such as tissue stiffness and stromal architecture further shape colonisation and outgrowth. Key mechanosensors—including focal adhesion kinases, ion channels and transcriptional regulators—translate force into biochemical signals, coordinating cytoskeletal remodelling, gene expression and metabolic changes. A detailed understanding of these processes offers new avenues for therapeutic intervention, from matrix‐targeted agents that normalise tissue mechanics to microfluidic platforms for circulating tumour cell capture and characterisation.

Research from Nature Portfolio

Recent studies have identified the transcriptional co-activator YAP1 as a critical fluid mechanosensor in circulating tumour cells. Exposure to physiologically relevant shear stress enhances YAP1 nuclear localisation and drives a gene programme that promotes invasion, chemotaxis and adhesion downstream of the ROCK–LIMK–cofilin axis; disruption of the YAP1–TEAD interface attenuates force-induced motility. Complementary microfluidic models replicating exercise-level shear stresses have revealed that high‐magnitude shear preferentially induces necrosis and apoptosis in highly metastatic cells, while sparing non-malignant cells. These foundational insights demonstrate that mechanical forces can both enhance metastatic potential via mechanotransduction and impose biophysical restraints on circulating tumour cell survival.

Mechanotransduction: The conversion of mechanical stimuli into intracellular biochemical signals that regulate cell behaviour.

YAP1: A transcriptional co-activator that translocates to the nucleus in response to mechanical cues and regulates gene expression programmes linked to growth and migration.
