PIEZO1 and cancer: These mechanical signals are transmitted through mechanosensitive pathways, with the Piezo channel family (Piezo1/Piezo2) serving as a core mediator.With their propeller-like trimeric structure, Piezo channels sense membrane tension, mediate calcium influx, and activate downstream signaling pathways (e.g., MAPK, PI3K/AKT/mTOR, YAP/TAZ), thereby regulating tumor cell proliferation, migration, immune microenvironment remodeling, and cancer stem cell-like transformation.
