摘要: 目的 明确卵巢衰老(OVA)加剧缺血性脑卒中(IS)损伤的病理机制,及基于病理靶点筛选的姜黄素对该类脑卒中损伤的作用机制。方法 挖掘GEO数据库中OVA(GSE81579)与IS(GSE16561)相关数据集,经差异表达分析、GSEA富集及Venn分析筛选核心交集基因,结合David数据库进行KEGG/GO富集分析;通过Coremine Medicine数据库筛选相关中药,并结合文献筛选活性成分;以雌性SD大鼠构建大脑中动脉阻塞/再灌注(MCAO/R)模型,分为假手术(Sham)组、MCAO/R组、卵巢切除+MCAO/R(M&OVA)组、卵巢切除+MCAO/R+姜黄素治疗(M&OVA&Cur)组和卵巢切除+MCAO/R+姜黄素治疗+烟酰胺(M&OVA&Cur&Nico)组,采用神经功能评分、TTC染色、HE染色、免疫荧光、透射电镜及蛋白质免疫印迹实验验证姜黄素的作用。结果 OVA与IS核心基因有80个交集,富集于炎症反应、C-X3-C趋化因子结合和NOD样受体信号通路等;筛选出中药姜黄及其活性成分姜黄素。动物实验显示,相较于MCAO/R组,M&OVA组大鼠脑损伤程度显著增加;200 mg/(kg·d)姜黄素可缓解M&OVA大鼠神经功能损伤,减小脑梗死体积并抑制NLRP3炎性小体活性。SIRT1抑制剂烟酰胺处理后,姜黄素保护作用减弱。结论 卵巢衰老通过激活炎症反应进一步加剧缺血性脑卒中的损伤,姜黄素可通过调控SIRT1-NLRP3轴减轻这一损伤。

Abstract: Objective To explore the pathological mechanism underlying the exacerbation of ischemic stroke(IS)injury by ovarian aging(OVA),and to elucidate the therapeutic mechanism of curcumin screened based on pathological targets against OVA-aggravated IS injury.Methods Datasets of OVA(GSE81579)and IS(GSE16561)were retrieved from the Gene Expression Omnibus(GEO)database.Core intersecting genes were screened through differential expression analysis,Gene Set Enrichment Analysis(GSEA),and Venn analysis.The Database for Annotation,Visualization and Integrated Discovery(David)was used for Kyoto Encyclopedia of Genes and Genomes(KEGG)and Gene Ontology(GO)enrichment analyses.Potential traditional Chinese medicines(TCMs)were screened via the Coremine Medicine database,and their active ingredients were further identified through literature review.A middle cerebral artery occlusion/reperfusion(MCAO/R)model was established in female Sprague-Dawley(SD)rats.The rats were randomly divided into five groups:the sham operation(Sham)group,MCAO/R model group,ovariectomy combined with MCAO/R(M&OVA)group,ovariectomy+MCAO/R+curcumin treatment(M&OVA&Cur)group,and ovariectomy+MCAO/R+curcumin+nicotinamide intervention(M&OVA&Cur&Nico)group.Multiple detection methods including neurological function scoring,2,3,5-triphenyltetrazolium chloride(TTC)staining,hematoxylin-eosin(H&E)staining,immunofluorescence assay,transmission electron microscopy(TEM),and Western blot were adopted to verify the protective effect and mechanism of curcumin.Results A total of 80 core intersecting genes were identified between OVA and IS,which were mainly enriched in the inflammatory response,C-X3-C chemokine binding,and NOD-like receptor signaling pathways.Curcuma longa and its active ingredient curcumin were finally screened as the targeted therapeutic agent.In vivo animal experiments demonstrated that rats in the M&OVA group exhibited significantly aggravated cerebral injury compared with those in the sole MCAO/R group.Treatment with curcumin at the dose of 200 mg/kg per day remarkably alleviated neurological deficits,reduced cerebral infarct volume,and inhibited the activation of NLRP3 inflammasome in M&OVA rats.Moreover,the neuroprotective effects of curcumin were markedly abrogated after intervention with nicotinamide,a specific SIRT1 inhibitor.Conclusion Ovarian aging aggravates ischemic stroke injury by activating inflammatory responses.Curcumin can attenuate OVA-aggravated cerebral ischemic injury via regulating the SIRT1-NLRP3 signaling axis,which provides a reliable theoretical basis for the clinical treatment of OVA-complicated ischemic stroke.
