Here, we investigate the involvement of metabolite extrusion by organic anion transporter 3 (OAT3), which is highly expressed at the blood-brain barrier in mice, in this species difference. The efflux rate of radioactivity in the cerebrum of Oat3(-/-) mice at later phase was 20% of that of control mice. Thus, organic anion transporters in mouse brain would be involved in the low brain retention of radioactivity after (99m)Tc-ECD administration.}, pages = {585--588}, title = {OAT3-mediated extrusion of the (99m)Tc-ECD metabolite in the mouse brain.}, volume = {34}, year = {2014} }
