Traditional Chinese Medicine (TCM) has received increasing attention as a complementary approach or alternative to modern medicine. However, experimental methods for identifying novel targets of TCM herbs heavily relied on the current available herb-compound-target relationships. In this work, we present an Herb-Target Interaction Network (HTINet) approach, a novel network integration pipeline for herb-target prediction mainly relying on the symptom related associations. HTINet focuses on capturing the low-dimensional feature vectors for both herbs and proteins by network embedding, which incorporate the topological properties of nodes across multi-layered heterogeneous network, and then performs supervised learning based on these low-dimensional feature representations. HTINet obtains performance improvement over a well-established random walk based herb-target prediction method. Furthermore, we have manually validated several predicted herb-target interactions from independent literatures. These results indicate that HTINet can be used to integrate heterogeneous information to predict novel herb-target interactions.
作为现代医学的补充方法或替代方法，传统中医（TCM）受到了越来越多的关注。然而，识别中药新药靶点的实验方法严重依赖于当前可用的草药-化合物-靶点关系。在这项工作中，我们提出了一种草药-靶点相互作用网络（HTINet）方法，这是一种主要依赖于症状相关关联的用于草药-靶点预测的新型网络集成管道。HTINet专注于通过网络嵌入捕获草药和蛋白质的低维特征向量，该方法整合了跨多层异构网络的节点拓扑属性，然后基于这些低维特征表示进行监督学习。与一种成熟的基于随机游走的草药-靶点预测方法相比，HTINet的性能有所提高。此外，我们从独立文献中人工验证了几个预测的草药-靶点相互作用。这些结果表明，HTINet可用于整合异构信息以预测新的草药-靶点相互作用。
