摘要:

基于液相色谱-质谱联用仪(LC-MS)技术、网络药理学和动物实验探讨新加苁蓉菟丝汤(XJCRTST)通过颗粒细胞线粒体自噬途径促卵泡发育的分子生物学机制。通过LC-MS和网络药理学筛选出XJCRTST的主要成分、其治疗卵巢功能减退疾病靶点及通路。选取雌性SD大鼠分为模型组,西药组,XJCRTST高、中、低剂量组共5组。HE染色观测卵巢形态学变化;透射电镜观察卵巢颗粒细胞中线粒体结构形态及线粒体自噬体。结果表明,LC-MS技术鉴定出XJCRTST化合物共252个,其治疗卵巢功能减退类疾病潜在作用靶点42个,GO功能富集过程中主要涉及BP(1 168项)、CC(45项)和MF(59项),KEGG通路富集显示参与的通路有AGE-RAGE、Prolactin及TNF信号通路等,Mitophagy-animal过程中共富集了3个靶基因:Parkin/PINK1HIF1AMAPK8。动物实验表明,中药治疗组大鼠卵泡数量增多,闭锁卵泡减少。电镜观察中发现中药组线粒体肿胀减轻、线粒体自噬情况减少。综上得出XJCRTST治疗卵巢功能减退可能通过调节卵巢颗粒细胞中线粒体功能和线粒体自噬相关通路发挥其治疗作用。

Abstract:

Using light chromatography-mass spectrometry (LC-MS), network pharmacology, and animal experiments, we explored the molecular mechanism by which Xinjia Cistanche Tusi Decoction (XJCRTST) promotes follicular development through granulosa cell mitophagy. LC-MS and network pharmacology were used to screen for the main components of XJCRTST and its therapeutic targets and pathways related to hypoovarianism. Female Sprague-Dawley rats were divided into five groups: model group, western medicine group, and XJCRTST high dose, medium dose, and low dose groups. The morphological changes of the ovary were observed through hematoxylin and eosin staining, and the structure and morphology of mitochondria and mitophagosomes in ovarian granulosa cells were observed through transmission electron microscopy. Two hundred and fifty-two compounds were identified in XJCRTST, with 42 potential targets for treating hypoovarianism, and the Gene Ontology enrichment mainly involved biological process (1 168 items), cell composition(45 items), and molecular function(59 items). KEGG pathway enrichment showed that the pathways involved were AGE-RAGE, Prolactin and TNF signaling pathways. Three target genes Parkin/PINK1, HIF1A and MAPK8 were enriched in the Mitophagy-animal process.Animal experiments showed that the number of follicles increased and the atretic follicles decreased in the Chinese medicine treatment group. Electron microscopy found that mitochondrial swelling and mitophagy decreased in the Chinese medicine group. XJCRTST may play a therapeutic role in treating hypoovarianism by regulating mitochondrial function and mitophagy-related pathways in ovarian granulosa cells.
