摘要:

文题释义:

转录组测序:近年来,基于转录组学的研究方法为深入了解中医药干预脑缺血的分子机制和治疗靶点提供了新的途径,转录组测序可以帮助确定在缺血性脑卒中过程中基因表达的全貌。
黄连总碱:为黄连中的生物碱,文献报道其能减轻缺血再灌注损伤大鼠的炎症反应,降低肿瘤坏死因子α、单核细胞趋化蛋白1和白细胞介素1β表达水平。

摘要
背景:黄连清热燥湿、泻火解毒,黄连及其成分对脑缺血有显著的保护作用,基于网络药理学和转录组测序探究黄连总碱抗脑缺血的作用机制。
目的:在明确黄连总碱对脑缺血大鼠保护作用的基础上,基于网络药理学和转录组测序技术探讨黄连总碱干预脑缺血的作用机制。
方法:将SD大鼠随机分为假手术组、缺血再灌注组、阳性药物组和黄连总碱组,后3组采用改良线栓法制备大脑中动脉阻塞的缺血再灌注模型,假手术组不插入线栓,其余手术操作相同。通过TTC染色、Longa 5神经功能缺损评分、苏木精-伊红染色、尼氏染色评价黄连总碱对脑缺血再灌注模型大鼠的脑保护作用。对假手术组、缺血再灌注组、黄连总碱组大鼠脑组织进行转录组测序,通过差异表达基因筛选、基因本体论分析、京都基因与基因组百科全书分析以及转录组学与网络药理学关联分析,阐明黄连总碱干预脑缺血的作用特点,最后通过ELISA检测及免疫荧光染色对黄连总碱干预脑缺血的关键靶点进行验证。

结果与结论:①黄连总碱可降低缺血再灌注模型大鼠Longa 5神经功能缺损评分及脑梗死面积,增加神经元、尼氏小体数目;②黄连总碱治疗后差异表达基因的基因本体论功能富集分析包括炎症反应、分裂原活化蛋白激酶级联的正调控等生物学过程;京都基因与基因组百科全书通路富集分析主要涉及白细胞介素17信号通路、神经活性配体-受体相互作用、环磷腺苷信号通路等通路;③转录组分析发现黄连总碱主要调控的基因有前列腺素内过氧化物合酶2、脑源性神经营养因子、瞬间受体电位A1等;④采用网络药理学分析发现,黄连总碱中9个成分可能通过87个成分靶点关联到过氧化物合酶2、脑源性神经营养因子及瞬间受体电位A1而发挥作用;⑤ ELISA检测及免疫荧光染色结果进一步证实,黄连总碱调控脑缺血再灌注模型大鼠过氧化物合酶2、脑源性神经营养因子和瞬间受体电位A1的表达;⑥提示黄连总碱能明显改善脑缺血再灌注模型大鼠损伤,可能通过调控过氧化物合酶2、脑源性神经营养因子和瞬间受体电位A1而发挥作用。

Abstract: BACKGROUND: Coptis chinensis can clear heat, dry dampness, relieve fire, and detoxify. Coptis chinensis and its components have a significant protective effect on cerebral ischemia. The action mechanism of anti-cerebral ischemia of Coptidis Rhizoma Alkaloids was explored based on network pharmacology and transcriptome sequencing.
OBJECTIVE: Based on the study of the protective effects of Coptidis Rhizoma Alkaloids on cerebral ischemia of rats, the action mechanism of Coptidis Rhizoma Alkaloids intervention in cerebral ischemia was investigated by using network pharmacology and transcriptome sequencing technology. 
METHODS: The SD rats were randomly divided into sham operation group, ischemia/reperfusion group, positive drug group, and Coptidis Rhizoma Alkaloids group. The ischemia/reperfusion model of middle cerebral artery occlusion was prepared by modified thread method in the latter three groups. No thread was inserted and the other operations were the same in the sham operation group. TTC staining, Longa 5 neurological deficient score, hematoxylin and eosin staining, and Nissl staining were used to evaluate the protective effect of Coptidis Rhizoma Alkaloids on ischemia/reperfusion model rats. Transcriptome sequencing was performed on the brain tissues of rats in sham operation group, ischemia/reperfusion group, and Coptidis Rhizoma Alkaloids group. Differentially expressed genes, gene Ontology analysis, Kyoto encyclopedia of genes and genomes analysis, and Correlation Analysis of Transcriptomics and Network Pharmacology were used to elucidate the effect of Coptidis Rhizoma Alkaloids on cerebral ischemia. Finally, ELISA and immunofluorescence staining were used to verify the key targets of Coptidis Rhizoma Alkaloids in the intervention of cerebral ischemia.
RESULTS AND CONCLUSION: (1) Coptidis Rhizoma Alkaloids treatment decreased the Longa 5 neurological deficit scores and cerebral infarction area of ischemia/reperfusion model rats, increased the number of neurons and Nissl bodies. (2) Differentially expressed gene after Coptidis Rhizoma Alkaloids treatment analyzed by functional enrichment analysis of gene ontology includes biological processes such as inflammatory reaction and positive regulation of mitogen-activated protein kinase cascade. The enrichment analysis of Kyoto gene and genome encyclopedia analysis pathway mainly involves interleukin-17 signaling pathway, neuroactive ligand-receptor interaction, cyclic adenosine-3′,5′-mconophosphate signaling pathway and so on. (3) Analysis of transcriptomics showed that the main genes regulated by Coptidis Rhizoma Alkaloids were prostaglandin endoperoxide synthase 2, brain derived neurotrophic factor, and transient receptor potential A1. (4) Network pharmacology analysis revealed that nine components in Coptidis Rhizoma Alkaloids may exert their effects by associating with 87 targets related to prostaglandin endoperoxide synthase 2, brain derived neurotrophic factor, and transient receptor potential A1. (5) ELISA and immunofluorescence staining results further confirmed that Coptidis Rhizoma Alkaloids regulated the expression of prostaglandin endoperoxide synthase 2, brain derived neurotrophic factor, and transient receptor potential A1. (6) It is concluded that Coptidis Rhizoma Alkaloids treatment can significantly improve the injury in ischemia/reperfusion model rats, possibly by regulating prostaglandin endoperoxide synthase 2, brain derived neurotrophic factor, and transient receptor potential A1. 

Key words: Coptidis Rhizoma Alkaloids, cerebral ischemia, transcriptome sequencing, prostaglandin endoperoxide synthase 2, brain derived neurotrophic factor, transient receptor potential A1
