BACKGROUND: The marginal division, a new sub-region in rat brain striatum discovered in recent decades, has been found to closely relate to learning and memory function of the brain. The immediate-early genes such as c-fos and c-jun participate in the signal transduction of learning and memory in the marginal division. But what other intermediate events are initiated in the marginal division in the process of learning and memory?Cyclic adenosine monophosphate (cAMP) response element-binding protein (CREBP) is an molecule essential for the formation of long-term memory,and investigation of the expression and distribution of phosphorylated CREBP in the striatum may help understand the signal transduction mechanism in the striatum during learning and memory at the molecular level.OBJECTIVE: To investigate the expression of phosphorylated CREBP in rat brain stratum during learning and memory process.DESIGN: Completely randomized controlled study.SETTING: Institute of Neurosciences, Zhujiang Hospital of the First Military Medical University of Chinese PLA.MATERIALS: This experiment was conducted in the Institute of Neurosciences, Zhujiang Hospital of the First Military Medical University of Chinese PLA between April and August 2003. Totally 48 normal male adult SD rats were provided from the Experimental Animal Center of First Military Medical University, and after two Y-maze tests, 40 rats were selected for this study (MG-2 type, Sanshengxing electricity company).METHODS: The 40 SD rats were randomized into 4 equal groups. The rats in the first group were subjected to training to acquire dark avoidance reflex in a Y maze, those in the second group underwent sham training with only light stimulation in the Y maze without electricity on the floor.The rats in the third group were trained in the Y maze with electricity on the floor but not light stimulations, with the rest 10 rats serving as the control group subjected to sham training in the Y maze without either electric or light stimulations. After the training in the Y maze, the rats were sacrificed immunohistochemical detection of phosphorylated CREBP expression in the brain striatum.MAIN OUTCOME MEASURES: Expression of phosphorylated CREBPin rat brain striatum.RESULTS: All the 40 rats enrolled in this study were examined for phosphorylated CREBP expression. Positive expression of phosphorylated CREBP was observed in the medial marginal division of the brain striatum after the rats were trained in the Y maze with electric stimulation, but no obvious expression was seen in rats in the sham training or control groups.Massive expression of phosphorylated CREBP could be observed, typically,in the hippocampus, front prefrontal lobe cortex and cingulate gyrus of the rat brain.CONCLUSION: The transcriptional factor phosphorylated CREBP in the marginal division of the striatum participates in the signal transduction for learning and memory in rats receiving Y maze training to acquire dark avoidance reflex.
