摘要:

以四血管阻断法制备脑缺血再灌注损伤大鼠,海马CA1区神经元形态受损,神经元数量减少,海马组织cAMP反应元件结合蛋白、CCAAT/增强子结合蛋白的DNA结合活性降低,大鼠学习和记忆能力下降。提示cAMP反应元件结合蛋白和CCAAT/增强子结合蛋白的DNA结合活性下降,可能参与脑缺血再灌注损伤引起的神经元损伤和学习记忆能力下降。

Abstract:

The present study established a rat model of cerebral ischemia/reperfusion injury using four-vessel occlusion and found that hippocampal CA1 neuronal morphology was damaged, and that there were reductions in hippocampal neuron number and DNA-binding activity of cAMP response element binding protein and CCAAT/enhancer binding protein, accompanied by decreased learning and memory ability. These findings indicate that decline of hippocampal cAMP response element binding protein and CCAAT/enhancer binding protein DNA-binding activities may contribute to neuronal injury and learning and memory ability reduction induced by cerebral ischemia/reperfusion injury.

Key words: neural regeneration, brain injury, cerebral ischemia/reperfusion, hippocampus, cAMP response element binding protein, CCAAT/enhancer binding protein, DNA-binding activity, brain, grants-supported paper, neuroregeneration
