摘要:




文题释义:
跑台实验:一种广泛用于医学生物研究的实验方法,利用动物趋利避害的习性,在跑步机中安装有轻微电击的电极以此来刺激动物前进,主要用于评估实验动物的运动能力、心肺功能、耐力以及运动相关疾病等方面的应用。
小鼠学习记忆行为:指小鼠通过学习获取新信息或技能,并通过记忆保持和回忆这些信息或技能的行为过程,与神经科学、心理学等研究有密切联系。评估小鼠学习记忆行为,有助于学习、记忆相关疾病神经机制及药物研发的研究。

背景:目前学习记忆行为学检测是阿尔茨海默病药物研发和发病机制探索的重要技术手段,然而动物行为容易受到外界及自身器官、细胞功能、心理等影响因素的干扰,因此,研发合适且可有效反映动物认知行为的实验方法是探究阿尔茨海默病致病机制及防治的重要前提。
目的:利用两种动物模型验证跑台实验是一种评估小鼠学习记忆的新方法,通过水迷宫实验对比跑台测试小鼠学习和记忆能力的优劣。
方法:利用聚合酶链式反应和硫磺素S染色检测APP/PS1转基因小鼠(阿尔茨海默病组,n=8)与同窝对照野生型小鼠(对照组,n=8)的基因型以及脑内β-淀粉样蛋白病理特征。选取11月龄APP/PS1转基因小鼠(阿尔茨海默病组,n=8)及其同窝野生型小鼠(对照组,n=8)进行跑台实验。选取8月龄3×Tg-AD小鼠(阿尔茨海默病组,n=8)和野生型对照小鼠(对照组,n=8),分别进行跑台和水迷宫实验。
结果与结论:①聚合酶链式反应结果显示APP/PS1转基因小鼠的APP和PSEN1基因表达高于对照组(P <  0.001),硫磺素S染色显示APP/PS1转基因小鼠脑内海马区的β-淀粉样蛋白斑块多于对照组(P <  0.001);跑台实验结果显示,APP/PS1转基因小鼠总电击次数及总电击时间均高于对照组(P < 0.05)。②跑台实验结果显示,3×Tg-AD小鼠的总电击次数及总电击时间均高于对照组(P < 0.05);水迷宫实验结果显示,3×Tg-AD
小鼠从定位航行阶段的第4天开始逃避潜伏期长于对照组(P < 0.05)。③结果表明跑台实验可以有效反映小鼠学习记忆功能,可能成为一种衡量小鼠认知行为的实验手段。

Abstract: BACKGROUND: Currently, behavioral tests for assessing learning and memory are important technical methods for the drug development and exploration of the pathogenesis of Alzheimer's disease. However, animal behavior is easily influenced by various factors, including external conditions, the function of internal organs and cells, and psychological states. Therefore, developing appropriate experimental methods that can effectively reflect animal cognitive behavior is an important prerequisite for exploring the pathogenic mechanism and prevention and treatment of Alzheimer’s disease.
OBJECTIVE: To verify that the treadmill test is a new method using two different mouse models and to explore the advantages and disadvantages of the treadmill test in evaluating the learning and memory ability of mice in comparison with the Morris water maze.
METHODS: The genotypes of APP/PS1 transgenic mice (Alzheimer’s disease group, n=8) and littermate wild-type mice (control group, n=8) and the pathological features of β-amyloid in the brain were identified using polymerase chain reaction and thioflavin S staining. Subsequently, 11-month-old APP/PS1 transgenic mice (Alzheimer’s disease group, n=8) and their littermates of wild-type mice (control group, n=8) were subjected to a treadmill test. At the same time, 8-month-old 3×Tg-AD mice (Alzheimer’s disease group, n=8) and wild-type control mice (control group, n=8) were subjected to treadmill and water maze tests sequentially.
RESULTS AND CONCLUSION: (1) The polymerase chain reaction results showed that the expression of APP and PSEN1 genes in APP/PS1 transgenic mice was higher than that in the control group (P < 0.001), and thioflavin S staining showed that there were more β-amyloid plaques in the hippocampus of APP/PS1 transgenic mice than in the control group (P < 0.001). The results of the treadmill test showed that the total number and duration of electric shocks in APP/PS1 transgenic mice were higher than those in the control group (P < 0.05). (2) The results of the treadmill test showed that the total number and duration of electric shocks in 3×Tg AD mice were higher than those in the control group (P < 0.05). The results of the water maze test showed that the escape latency of 3×Tg AD mice was longer than that of the control group from the 4th day of the localization navigation phase (P < 0.05). To conclude, the treadmill test can effectively reflect the learning and memory function of mice, and may become an experimental method for measuring mouse cognitive behaviors.
