title: Isoforms of glucose transporter in the iris-ciliary body.
abstract: Isoforms of the facilitated glucose transporter (GLUT) were identified in the iris-ciliary body. Western blot analysis showed that GLUT1 and GLUT4 proteins were expressed in the rat iris-ciliary body. In addition, the content of GLUT proteins in the rabbit iris-ciliary body was estimated by specific [3H]cytochalasin B binding assay. The content of GLUT proteins was found to be more abundant in the iris-ciliary body than in the cerebral cortex. The utilization of glucose in the iris-ciliary body and the transport of glucose into the aqueous humor are suggested to be mediated by GLUT1 and GLUT4 proteins.
