title: Postnatal changes in glucose transporter 3 expression in the dentate gyrus of the C57BL/6 mouse model.
abstract: In this study, we observed the ontogenetic changes in glucose transporter 3 (GLUT3) immunoreactivity, a major neuronal GLUT, in the dentate gyrus of mouse brains at various ages: postnatal day (P) 1, 7, 14, 28, and 56. At P1, cresyl violet staining showed abundant neurons in the dentate gyrus, whereas the granule cell layer was ill-defined. At P7, the granule cell layer was observed, and cresyl violet-positive cells were dispersed throughout the polymorphic layer. At P14, the granule cell layer was well-defined, and cresyl violet positive cells were detected abundantly in the polymorphic layer. At P28 and P56, cresyl violet-positive cells were observed in the granule cell layer, as well as in the polymorphic layer. At P1, GLUT3 immunoreactivity was detected in the dentate gyrus. At P7, GLUT3 immunoreactive cells were scattered in the polymorphic and molecular layer. However, at P14, GLUT3 immunoreactivity was observed in the polymorphic layer as well as subgranular zone of the dentate gyrus. At P28, GLUT3 immunoreactivity was detected in the polymorphic layer of the dentate gyrus. At P56, GLUT3 immunoreactivity was observed predominantly in the subgranular zone of the dentate gyrus. GLUT3 immunoreactive cells were mainly colocalized with doublecortin, which is a marker for differentiated neuroblasts, in the polymorphic layer and subgranular zone of dentate gyrus at P14 and P56. These results suggest that the expression of GLUT3 is closely associated with postnatal development of the dentate gyrus and adult neurogenesis.
