摘要(Abstract):
目的 探索中药干预DNA高甲基化的物质基础及用药规律。方法 首先,整合GeneCards、OMIM、GenCLip 3等数据库,从中获取可作用于DNA高甲基化的相关靶点,然后利用中药系统药理学数据库与分析平台(TCMSP)筛选出类药性≥0.18的靶点,并收集其相关化合物及中药,构建靶点-化合物、靶点-化合物-中药网络,分析靶点、化合物、中药之间的相关性。另外,匹配中药的性味归经等信息,分析用药规律。最后,将网络中核心靶点与化合物进行分子对接,以验证预测结果及进一步挖掘潜在的化合物靶点组合。结果 共得到189个可作用于DNA高甲基化的靶点,其中有35个靶点可匹配到候选化合物且类药性≥0.18,匹配到1 188个候选化合物,共408味中药。频数统计结果显示,干预DNA高甲基化的中药药味以苦、辛、甘为主,药性以温居多,主要归肝、肺二经。结论 本研究通过系统探讨中药干预DNA高甲基化的物质基础及用药规律,可为中药去甲基化的理论研究及临床应用提供新思路。
