目的:
2
基于网络药理学方法研究海蓬子(SE)的药效物质基础、作用机制及靶向性疾病
并通过药理学试验验证海蓬子提取物的抗抑郁作用.
方法:
2
利用中药(CM)、PubMed、PharmMapper、MAS 3.0、Cytoscape等检索工具
搜索海蓬子的成分
预测其靶点及相关治疗疾病
构建海蓬子治疗中枢神经系统疾病的 "成分-靶点-通路" 网络. 进一步地
通过分析蛋白-蛋白交互网络及抗抑郁靶点的KEGG和GO功能注释来预测海蓬子的抗抑郁作用机制. 采用慢性不可预知温和应激 (CUMS) 方法建立具有抑郁症状的小鼠模型. 动物被随机分为6组
包括对照组 (无应激刺激且给予蒸馏水) 、模型组 (给予CUMS模型小鼠蒸馏水) 、文拉法辛组 (给予CUMS模型小鼠9.38 mg/kg文拉法辛) 、海蓬子高
中
低剂量组 (分别给予CUMS模型小鼠1.8
1.35
0.9 g/kg海蓬子) . 通过强迫游泳实验 (FST) 、悬尾实验 (TST) 和旷场实验 (OFT) 对相关指标进行了实验验证. 采用酶联免疫吸附法 (ELISA) 和免疫印迹法 (WB) 分别检测海马、大脑皮层中多巴胺(DA)的浓度
血液中白细胞介素-2 (IL-2) 和皮质醇 (CORT) 的水平
以及小鼠的核因子E2相关因子2 (Nrf2)
甲藻样环氧氯丙烷相关蛋白1 (Keap1)

Objective:
2
To investigate the pharmacodynamic material basis
mechanism of actions and targeted diseases of
Salicornia europaea
L. (SE) based on the network pharmacology method
and to verify the antidepressant-like effect of the SE extract by pharmacological experiments.
Methods:
2
Retrieval tools including Chinese medicine (CM)
PubMed
PharmMapper
MAS 3.0 and Cytoscape were used to search the components of SE
predict its targets and related therapeutic diseases
and construct the "Component-Target- Pathway" network of SE for central nervous system (CNS) diseases. Further
protein-protein interaction (PPI) network
Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) function annotation of depression-related targets were analyzed to predict the antidepressant mechanism of SE. Chronic unpredictable mild stress (CUMS) model was used to construct a mouse model with depression-like symptoms. And the animals were randomly divided into 6 groups (
n
=10) including the normal group (nonstressed mice administered with distilled water)
the CUMS group (CUMS mice administered with distilled water)
the venlafaxine group (CUMS mice administered with venlafaxine 9.38 mg/kg)
SE high-
medium-
and low-dose groups (CUMS mice administered with SE 1.8
1.35 and 0.9 g/kg
respectively). Then some relevant indicators were determined for experimental verification by the forced swim test (FST)
the tail suspension test (TST) and open-field test (OFT). Dopamine (DA) concentration in hippocampus and cerebral cortex
IL-2 and corticosterone (CORT) levels in blood
and nuclear factor E2 related factor 2 (Nrf2)
kelch-like epichlorohydrin related protein 1 (Keap1)
NAD(P) H dehydrogenase [quinone] 1 (NQO1) and heme oxygenase-1 (HO-1) levels in mice were measured by enzyme linked immunosorbent assay (ELISA) and Western blot respectively to explore the possible mechanisms.
Results:
2
The "target-disease" network diagram predicted by network pharmacology
showed that the potential target of SE involves a variety of CNS diseases
among which depression accounts for the majority. The experimental results showed that SE (1.8
1.35 g/kg) significantly decreased the immobility period
compared with the CUMS group in FST and TST in mice after 3-week treatment
while SE exhibited no significant effect on exploratory behavior in OFT in mice. Compared with CUMS group
the SE group (0.9 g/kg) showed significant differences (
P
<
0.05) in DA levels in the hippocampus and cerebral cortex. In addition
compared with CUMS control group
SE (1.8 g/kg) group showed a significant effect on decreasing the activities of CORT (
P
<
0.05)
and serum IL-2 level with no statistical significance. Finally
Western blot results showed that compared with the model group
Nrf2
Keap1
NQO1 and HO-1 protein expressions in SE group (1.8 g/kg) were up-regulated (all
P
<
0.01).
Conclusion:
2
The SE extract may have an antidepressant effect
which appeared to regulate Nrf2-ARE pathway and increased levels of DA and CORT in the hippocampus and cortex.
