Outline of Final Research Achievements

In this study, we found 11 Rho-GEFs, which are upstream activator of Rho family small GTPases, involved in cyclic stretch-induced cell orientation in vascular endothelial cells. We focused on Solo, which is one of those Rho-GEFs, and found that Solo is required to orient the cells in response to the force derived from cadherin-based cell-cell adhesion. We also showed that Solo is required to activate RhoA and the formation of stress fibers by tensile-force application in epithelial cells.
