Methods: From TCMSP, OMIM, Drugbank, GeneCards and PharmGkb databases, the potential active components, target sites and differential genes of the disease were determined, and the intersection of the two was selected. Cytoscape 3.9.0 software was used to construct the regulatory network diagram of “Traditional Chinese Medicine, active ingredient, intersection target-disease”, and PPI network of ovulatory dysfunction infertility was constructed with string data. Functional enrichment analysis of GO and KEGG was performed using R packets. Results: Eighteen compound components and 59 drug targets were determined by TCMSP database.

不孕症是妇科常见的难治性疾病,近年来不孕症患病率逐渐上升,已经成为影响女性生殖健康的重要疾病,其中排卵障碍型不孕症约占女性不孕症的20%~30% [
蛇床子是传统医学中常用的攻毒、杀虫、止痒类药物,其温肾助阳的功效常被忽略,《本草崇原》记载:“蛇床子,不独助男子,且有益妇人,乃世人舍此而求补药于远域,且近时但用为疮药,惜哉。”国医大师何成瑶教授将蛇床子作为治疗排卵障碍型不孕的核心用药之一,取得了良好的临床疗效,但其具体作用机制尚不清楚 [
采用TCMSP数据库及查阅相关文献筛选蛇床子的有效成分及药物靶点。有效成分筛选标准为:口服生物利用度(Oral bioavailability, OB) ≥ 30%,类药性(Drug likeness, DL) ≥ 0.18。
基于TCMSP 2.3,将蛇床子的多个活性成分与潜在作用靶点逐个配对,筛选结束后,把蛇床子活性成分作用的蛋白质通过UniProt蛋白数据库(https://www.uniprot.org)进行标准化,继而得到靶点蛋白的官方名称,以此可以预测蛇床子活性的作用靶点。
用“Anovulatory infertility”作为关键词,在人类孟德尔遗传数据库Drugbank、GeneCards、OMIM、PharmGkb数据库中检索,得到排卵障碍型不孕症的相关靶点。与上述蛇床子的活性成分预测作用靶点取交集,得到蛇床子治疗排卵障碍型不孕症的作用靶点。
使用Cytoscape 3.9.0软件构建“中药–活性成分–交集靶点–疾病”调控网络图,并进行拓扑分析,通过Cytoscape 3.9.0软件中计算连接度(Degree)参数来评判药效成分与靶点的重要性。
将蛇床子治疗排卵障碍型不孕症的潜在作用靶点输入STRING数据库(https://string-db.org/),物种设定为“Homo sapiens”,获得蛋白与蛋白之间的相互作用关系,将数据保存为TSV格式,获得PPI网络信息,将信息导入Cytoscape 3.9.0,绘制PPI网络并进行拓扑分析。
为了研究与潜在目标相关的生物学功能,我们通过“clusterProfiler”R包进行了基因本体论(GO)和京都基因和基因组百科全书(KEGG)通路富集分析。“clusterProfiler”R包作为一种富集工具,具有基于多种资源的集成基因聚类分析。GO富集分析从三个维度对基因进行解释和注释,包括细胞成分(CC)、分子功能(MF)和生物过程(BP)分析。KEGG数据库主要用于通路分析。P ≤ 0.05被认为具有统计学意义。
蛇床子有18个化合成分,59个药物靶标。其中,beta-sitosterol、Stigmasterol、o-Isovaleryl columbianetin、O-Acetylcolumbianetin、Xanthoxylin N等物质是蛇床子中含有排卵障碍型不孕症靶点较多的成分。
1618个疾病靶点与59个药物靶标取交集后,共获得21个差异基因(见图1)。

使用Cytoscape 3.9.0绘制蛇床子有效成分治疗排卵障碍型不孕症的基因网络图(图2)。基于蛇床子活性成分与排卵障碍型不孕症疾病靶点的相互作用,采用Cytoscape软件构建“药物–活性成分–交集靶点–疾病”网络,结果见图2。图中39个节点分别代表药物、疾病、交集靶点、活性成分等,79个线代表两节点之间的互作关系。结果显示,其中度值前五的药物分别是beta-sitosterol、Stigmasterol、o-Isovaleryl columbianetin、O-Acetylcolumbianetin、Xanthoxylin N。度值前五的靶点是PTGS2、PTGS1、HSP90AA1、NCOA2、ADRB2。
结果见图3。AR、CASP3、MET、PGR、HSP90AA1、PTGS2、ESR1、NCOA2、NCOA1、BAX、CASP9、BCL2、KDR、NOS2、PLAU、OPRM1、PTGS1可能是在蛇床子治疗排卵障碍型不孕症中发挥重要作用的核心靶点。
基因本体(GO)分析结果显示(图4),生物过程(BP)涉及类固醇激素反应、生殖腺发育、排卵周期、生殖结构发育、生殖系统发育、节律过程、细胞对药物的反应、细胞对类固醇激素刺激的反应、细胞内类固醇激素受体信号通路。细胞成分(CC)涉及孔隙复合体、薄膜筏、膜微区、膜区、髓磷脂鞘、核染色质、枝晶末端、神经元细胞体、内吞囊腔、转录活性染色质、高密度脂蛋白颗粒、蛋白质–脂质复合物。分子功能(MF)涉及半胱氨酸型内肽酶活性与凋亡过程、肾上腺素能受体活性、类固醇结合、RNA聚合酶II通用转录起始因子结合、儿茶酚胺结合、核受体结合、四吡咯结合、雌激素受体结合、一般转录起始因子结合、激素受体结合。

基因组百科全书(KEGG)分析结果表明(图5),蛇床子治疗排卵障碍型不孕症的信号通路包括雌激素信号通路、细胞凋亡、p53信号通路、甲状腺激素信号通路、VEGF信号通路、PI3K-Akt信号通路、IL-17信号通路、内分泌抵抗、NF-κB信号通路、钙信号通路、血清素能突触、内质网中的蛋白质加工、花生四烯酸代谢、孕激素介导的卵母细胞成熟、HIF-1信号通路、TNF信号通路、MAPK信号通路、鞘磷脂信号通路、神经营养素信号通路、卵母细胞减数分裂、精氨酸生物合成。
排卵障碍是女性不孕症的重要原因之一,约占女性不孕症的20%~30%。现代医学认为排卵障碍的发生主要涉及下丘脑–垂体–卵巢轴病变及其他一些内分泌病变 [
本研究表明,beta-sitosterol、Stigmasterol、o-Isovaleryl columbianetin、O-Acetylcolumbianetin、Xanthoxylin N等物质是蛇床子中含有排卵障碍型不孕症靶点较多的成分。其中,β-谷甾醇(beta-sitosterol)是一种植物甾醇类雌激素,研究表明,β-谷甾醇(beta-sitosterol)具有雌激素活性,可作用于卵巢颗粒细胞促进其产生E2,E2能够维持卵泡的生长发育 [
PPI结果显示,AR、CASP3、PGR、PTGS2、ESR1等关键靶点参与了排卵障碍型不孕症的发展,且能被蛇床子所干预。AR是一种类固醇受体蛋白,Takeda [
KEGG结果表明,蛇床子对排卵障碍型不孕症患者雌激素信号通路、细胞凋亡、VEGF信号通路、PI3K-Akt信号通路、IL-17信号通路等信号传导途径起到主要调控作用。大量研究证明,雌激素信号通路与卵母细胞的生长发育及排卵过程密切相关。雌激素通过两种信号通路介导其细胞作用,这两种信号通路被分为“核起始的雌激素信号通路”和“膜起始的雌激素信号通路” [
