方法:在中药系统药理学数据库与分析平台(TCMSP)中查找浙贝母和山慈菇这两味中药的活性成分,检索有效活性成分的作用靶点,利用Uniprot将各作用靶点转换成基因通用名。
在OMIM、GeneCards数据库中分别筛选和甲状腺癌有关的靶点,通过Cytoscape3.7.1软件把得到的结果进行可视化,绘制药物 成分 靶点网络图及核心靶点的蛋白质 蛋白质相互作用网络,将药物作用靶点与疾病靶点采用Metascape在线数据库进行京都基因与基因组百科全书(KEGG)及基因本体(GO)功能富集分析。
结果:浙贝母 山慈菇药对调治甲状腺癌的核心成分有10种,其潜在的作用靶点有75个;数据库筛选出与甲状腺癌相关的疾病作用靶点2357个,甲状腺癌疾病核心靶点96个,其中NPM1、HSPA5、HDAC5等基因较为关键。
GO功能富集分析细胞组分主要与核糖核蛋白复合物有关,分子功能主要与组蛋白脱乙酰酶结合有关,生物过程主要与调节细胞对压力的反应有关。
KEGG信号通路富集主要包括新型冠状病毒感染、细胞凋亡、剪接体及缺氧诱导因子 1(HIF 1)信号通路和细胞周期等信号通路有关。
结论:浙贝母 山慈菇药对干预甲状腺癌的机制包含多靶点、多通路,可为后续临床应用及药物开发提供理论依据和方向。
