Hippo/yes-associated protein signaling functions as a mechanotransducer in regulating vascular homeostasis.

Cells are constantly exposed to various mechanical forces, including hydrostatic pressure, cyclic stretch, fluid shear stress, and extracellular matrix stiffness. Mechanical cues can be translated into the cell-specific transcriptional process by a cellular mechanic-transducer. Evidence suggests that mechanical signals assist activated intracellular signal transduction pathways and the relative phenotypic adaptation to coordinate cell behavior and disease appropriately. The Hippo/yes-associated protein (YAP) signaling pathway is regulated in response to numerous mechanical stimuli. It plays an important role in the mechanotransduction mechanism, which converts mechanical forces to cascades of molecular signaling to modulate gene expression. This review summarizes the recent findings relevant to the Hippo/YAP pathway-based mechanotransduction in cell behavior and maintaining blood vessels, as well as cardiovascular disease. • How the mechanical cues are sensed and transduced at the molecular level to regulate gene expression remained elusive. • Hippo/YAP functioned as a mechanotransduction switch of mechanical forces, and translated them into transcriptional process. • Hippo/YAP function as a mechanotransducer in cell behavior, blood vessels maintenance, and cardiovascular diseases.
