Abstract
Cyclic AMP (cAMP) response element-binding protein (CREB) is involved in memory, learning, and synaptic transmission. In this study, we observed changes of phosphorylated CREB (pCREB) immunoreactivity and its protein levels as well as brain-derived neurotrophic factor (BDNF) levels in the hippocampal dentate gyrus at postnatal (P) 1, 7, 14, and 21 in mice. In addition, we also investigated pCREB expression in doublecortin (DCX, a marker for neuronal progenitors) immunoreactive neuroblasts at P21. pCREB immunoreaction at P1 was detected in most of cells in the dentate gyrus, thereafter pCREB immunoreactivity was decreased in all the layers of the dentate gyrus with time, however, strong pCREB immunoreactivity was shown in cells confined to the subgranular zone of the dentate gyrus at P21. In this group, many pCREB immunoreactive cells were co-localized with DCX immunoreactive neuroblasts. In addition, pCREB protein levels were decreased with age, showing that their levels were very low at P21, while BDNF protein levels were increased with age. These results suggest that pCREB may play important roles in functional maturity of granule cells in mice.
