Rho is known to be involved in cell motility, cell adhesion, and cytokinesis through actin cytoskeleton reorganization. The GTP-bound form of Rho interacts with its specific downstream target, triggering intracellular signaling cascades. Rho effectors such as Rho-kinases have been isolated on the basis of their selective binding to the GTP-bound form of Rho. Rho-kinase is thought to have an important role in the pathogenesis of a variety of neurological diseases because activation of the Rho/Rho-kinase pathway has been observed in various central nervous system disorders. Previous histochemical studies have shown multiple molecular mechanisms for the regulation of Rho-kinase. Neuroimaging of Rho/Rho-kinase has rarely been studied because of a lack of appropriate radiotracers. Recently, N-[(11)C]methyl-hydroxyfasudil, a new radiotracer for positron emission tomography (PET), has been introduced to measure Rho-kinase activity. In this study, the regional distribution and kinetics of N-[(11)C]methyl-hydroxyfasudil were investigated in the brains of mice.}, pages = {395--402}, title = {Evaluation of Rho-Kinase Activity in Mice Brain Using N-[(11)C]Methyl-hydroxyfasudil with Positron Emission Tomography.}, volume = {16}, year = {2013} }
