The cyclic AMP response element-binding protein (CREB) and nerve growth factor (NGF) have been proposed as key modulators of brain health and are involved in synaptic plasticity. The study investigates how combined water-based training affects hippocampal neuron plasticity and memory function in old rats.
16 Wistar male rats 24-month-old were randomly divided into two groups: combined training (n = 8) and control (n = 8). Four sessions were performed per week for 10 weeks, and consisted of resistance and endurance training in water. The control group was placed in a water container during training for 30 minutes to be homogenized in terms of the stress conditions. The.NGF and CREB genes in the hippocampus were evaluated and the working memory was measured using real-time PCR and Y-maze tests. The SPSS 26 software was utilized in which independent t-tests were used to analyze the genes and the Mann-Whitney U test was used to analyze functional memory with a significant level of (P < 0.05).
The combined training resulted in a significant rise in NGF and CREB gene expression in the hippocampus tissue of elderly rats compared to the control group (P < 0.05); however, there was no notable difference in the Y maze performance test between the two groups (P < 0.05).
These findings suggest that water-based combined training has beneficial effects on gene expression of NGF and CREB; however, it is necessary to conduct more studies to comprehend the effects of combined training on memory function.
环磷酸腺苷反应元件结合蛋白(CREB)和神经生长因子(NGF)被认为是脑健康的关键调节因子,且参与突触可塑性。本研究调查了联合水基训练如何影响老年大鼠海马神经元可塑性和记忆功能。
将16只24月龄的雄性Wistar大鼠随机分为两组:联合训练组(n = 8)和对照组(n = 8)。每周进行4次训练,共10周,训练包括水中的阻力训练和耐力训练。对照组在训练期间置于水容器中30分钟,以使其在应激条件方面达到均衡。采用实时定量聚合酶链反应(real-time PCR)和Y迷宫测试评估海马中的NGF和CREB基因,并测量工作记忆。使用SPSS 26软件,其中独立样本t检验用于分析基因,曼-惠特尼U检验用于分析功能记忆,显著性水平为(P < 0.05)。
与对照组相比,联合训练导致老年大鼠海马组织中NGF和CREB基因表达显著升高(P < 0.05);然而,两组在Y迷宫性能测试中没有显著差异(P < 0.05)。
这些发现表明,联合水基训练对NGF和CREB的基因表达有有益影响;然而,有必要进行更多研究以了解联合训练对记忆功能的影响。
