In recent years, many experiments have proved that microRNAs (miRNAs) play a variety of important regulatory roles in cells, and their abnormal expression can lead to the emergence of specific diseases. Therefore, it is greatly valuable to do research on the association between miRNAs and diseases, which can effectively help prevent and treat miRNA-related diseases. At present, effective computational methods still need to be developed to better identify potential miRNA-disease associations. Inspired by graph convolutional networks, in this study, we propose a new method based on Attention aware Multi-view similarity networks and Hypergraph learning for MiRNA-Disease Associations identification (AMHMDA). First, we construct multiple similarity networks for miRNAs and diseases, and exploit the graph convolutional networks fusion attention mechanism to obtain the important information from different views. Then, in order to obtain high-quality links and richer nodes information, we introduce a kind of virtual nodes called hypernodes to construct heterogeneous hypergraph of miRNAs and diseases. Finally, we employ the attention mechanism to fuse the outputs of graph convolutional networks, predicting miRNA-disease associations. To verify the effectiveness of this method, we carry out a series of experiments on the Human MicroRNA Disease Database (HMDD v3.2). The experimental results show that AMHMDA has good performance compared with other methods. In addition, the case study results also fully demonstrate the reliable predictive performance of AMHMDA.
近年来,许多实验证明,微小RNA(miRNA)在细胞中发挥着多种重要的调控作用,其异常表达会导致特定疾病的出现。因此,研究miRNA与疾病之间的关联具有重要价值,这有助于有效预防和治疗与miRNA相关的疾病。目前,仍需开发有效的计算方法,以更好地识别潜在的miRNA-疾病关联。受图卷积网络的启发,在本研究中,我们提出了一种基于注意力感知多视图相似性网络和超图学习的miRNA-疾病关联识别新方法(AMHMDA)。首先,我们构建了多个miRNA和疾病的相似性网络,并利用图卷积网络融合注意力机制从不同视图中获取重要信息。然后,为了获得高质量的链接和更丰富的节点信息,我们引入了一种称为超节点的虚拟节点来构建miRNA和疾病的异构超图。最后,我们采用注意力机制融合图卷积网络的输出,预测miRNA-疾病关联。为了验证该方法的有效性,我们在人类微小RNA疾病数据库(HMDD v3.2)上进行了一系列实验。实验结果表明,与其他方法相比,AMHMDA具有良好的性能。此外,案例研究结果也充分证明了AMHMDA可靠的预测性能。
