Insulin induces glucose transporter 4 (GLUT4) translocation to the muscle cell surface. As fagopyritol has insulin-like effects, the effects of fagopyritol on GLUT4 translocation and filamentous (F) actin remodeling in L6-GLUT4myc skeletal muscle cells were investigated. Fagopyritol significantly increased plasma membrane GLUT4 levels compared with the basal control in L6-GLUT4myc myoblast cells. Phosphatidylinositol (PI) 3-kinase inhibitor (LY294002) treatment prevented GLUT4 translocation to

In addition, fagopyritol treatment induced GLUT4 translocation and F-actin remodeling in myotubes. Taken together, these results suggest that fagopyritol promotes GLUT4 translocation and F-actin remodeling by activating the PI 3-kinase-dependent signaling pathway.
