摘要:
目的:采用慢性温和不可预知应激法制作小鼠抑郁模型,探究金郁欢治疗抑郁小鼠所涉及的相关机制。方法:将60只ICR小鼠进行随机分配,设立以下五个组别:对照组、模型组、低剂量金郁欢处理组、高剂量金郁欢处理组以及氟西汀治疗组,每组12只。悬尾实验观察动物抑郁样行为; 尼氏染色检测小鼠海马CA3区尼氏小体平均黑度; 免疫组织化学法、Western blotting检测Wnt1和GSK-3β蛋白水平; RT-PCR检测Wnt1和GSK-3β mRNA表达情况。结果:相较于对照组,模型组小鼠在悬尾测试中的静止持续时间出现了明显的延长,尼氏小体平均黑度值降低,Wnt1、Wnt1 mRNA表达减少,GSK-3β、GSK-3β mRNA表达增多。与模型组相比,金郁欢组悬尾静止时间缩短,尼氏小体平均黑度值升高,Wnt1、Wnt1 mRNA表达增多,GSK-3β、GSK-3β mRNA表达减少。结论:金郁欢可有效改善抑郁症小鼠抑郁样行为,通过改变Wnt1、GSK-3β蛋白表达,发挥抗抑郁作用。
Abstract:
Objective:A chronic mild unpredictable stress method was used to create a mouse model of depression and exploring the relevant mechanisms involved in the treatment of depressed mouse with Jin Yuhuan(JYH).Methods:Sixty ICR mice were randomly divided into control group,model group,JYH low-dose group,JYH high-dose group,and fluoxetine group,12 mice in each group.Tail suspension test was used to observe the depression-like behavior of the animals; Nissl staining was used to detect the average blackness of Nissl body in the CA3 region of the mice hippocampus.Immunohistochemistry and Western blotting were used to detect the protein levels of Wnt1 and GSK-3β; and RT-PCR was used to detect the expression of Wnt1 and GSK-3β mRNA.Results:Compared with the control group,mice in the model group had a significantly increased tail suspension test time,a decreased average blackness value of Nissl body,a decreased expression of Wnt1 and Wnt1 mRNA,and an increased expression of GSK-3β and GSK-3β mRNA.Compared with the model group,the tail suspension time was shortened in the JYH group,the average blackness value of Nissl body was increased,the expression of Wnt1,Wnt1 mRNA was increased,and the expression of GSK-3β,GSK-3β mRNA was decreased.Conclusion:JYH can effectively improve depressive-like behavior in depressed mice and exert antidepressant effects by altering Wnt1 and GSK-3β protein expression.
